This article reports findings from a peer-delivered intervention designed to increase use of breast and cervical cancer screening.
                Twenty-six worksites were randomly assigned to the intervention or comparison group. The 16-month intervention consisted of group discussions, outreach, and educational campaigns. Data were collected from a random sample of women employees stratified by age (baseline n = 2943; final n = 2747). Cross-sectional analyses were conducted to evaluate the impact of the intervention on screening behaviors.
                Relative to comparison worksites, the intervention group experienced greater increases in the percentage of women who reported a recent mammogram (7.2% vs 5.6%), clinical breast examination (5.8% vs 2.1%), and Papanicolaou (Pap) test (4.7% vs 1.9%). After worksite cluster and age strata were controlled for, the observed increase in Pap tests was significantly greater in the intervention group (odds ratio [OR] = 1.28; 95% confidence interval [CI] = 1.01, 1.62); however, differences in mammography screening rates (OR = 1.14; 95% CI = 0.90, 1.44) and clinical breast examination (OR = 1.19; 95% CI = 0.96, 1.49) were not statistically significant.
                Intervention activities produced a modest increase in cervical cancer screening, but they did not accelerate breast cancer screening rates above the observed secular trend. Evaluation of three potential methods for increasing Pap smear use: television media, television media combined with letter based recruitment, and television media combined with general practitioner based (GP based) recruitment.
                A trial of each intervention was carried out in three postal regions in New South Wales, Australia-a rural locality (containing about 1000 women), a country town (about 3000 women), and a major rural centre (about 10,000 women). Three control regions were selected to be demographically similar to the corresponding intervention regions.
                Outcome data on regional Pap smear rates were obtained from government health insurance claims for cervical screening, and from pathology service records. Expected Pap smear rates for the three months after the intervention were predicted from 45 pre-intervention months and were compared with observed rates for this period.
                Television media alone was associated with a significant increase in attendances for screening in one of the three regions where a trial was carried out: 13.3% in the rural centre. The media/letter based campaign was associated with a significant increase in attendances in two out of three regions: 52.7% in the rural locality, 43.2% in the rural centre. The media/GP based campaign was associated with significant increases in attendances in all three regions: 50.2% in the rural locality, 80.8% in the country town, 15.7% in the rural centre. All three interventions were associated with significant increases in the number of women attending for cervical screening above those observed in the control regions. Furthermore, these increases were not restricted to women at low risk. They were also found for older women (aged 50-69 years) and women who had not had a Pap smear within the past three years. Campaigns involving sending personally addressed letters to encourage women to have Pap smears increase Pap smear rates. The aim of this study was to assess whether this effect is maintained when campaigns are repeated regularly. In October 1992, a letter reminding women of the importance of screening was mailed to all women in three New South Wales postcode regions where a similar letter had been sent three years previously. The response was compared to the response in three regions receiving no earlier letter. The number of women attending for cervical screening during the three months after distribution of the letters was assessed from Health Insurance Commission claims for cervical cytology. These attendances were compared with expected attendances based on the attendance patterns over 28 pre-intervention quarters. Significant postintervention increases in attendance were observed in all three regions receiving an initial letter. However, in one region, the increase in attendances, around 1 per cent of eligible women, was not significantly greater than the increase in the control region (z = 0.15, P = 0.88). The second letter campaign had no measurable effect on attendances. No significant increase in screenings was observed in two of the towns. A significant increase was observed in one region, but this was not significantly greater than the increase in the control region (z = -0.05, P = 0.96). These results suggest that repeated direct-mail campaigns to promote screening for cervical cancer may be of no benefit. A one-off campaign may result in an increase in screenings in the short term. To compare the effectiveness and cost-effectiveness of three methods of inviting women with a long history of non-attendance to undergo cervical screening.
                Randomized controlled trial and cost-effectiveness analysis. In all, 1140 women were identified from routine NHS screening records as having no smear for at least 15 years and randomly allocated to receive a telephone call from a nurse, a letter from a well-known celebrity (Claire Rayner) or letter from the local NHS Cervical Screening Commissioner. Uptake of screening was measured using routine data and attributed to interventions if occurring within three months. Uptake was compared with a control group. Costs of carrying out the interventions were noted from the perspective of the NHS and cost-effectiveness, as cost per additional attender, calculated.
                Uptake following all interventions was low: telephone call (1.4, 95% confidence interval [CI] 0.38-3.6%); celebrity letter (1.8, 95% CI 0.57-4.0%); commissioner letter (4.6, 95% CI 2.5-7.7%); control group (1.8, 95% CI 0.57-4.0%). There were no significant differences between groups. Telephone intervention was not possible in a quarter of women whose numbers were unlisted. Telephone intervention was the most expensive and least effective of the interventions. The commissioner letter yielded an additional attender within three months at an incremental cost of 23.21 pounds compared with taking no action.
                Neither a telephone call from a nurse nor a letter from a celebrity to encourage attendance for cervical screening were effective or cost-effective in women with a prolonged history of non-participation in the screening programme. A letter from the local cervical screening programme commissioner resulted in a small, non-significant increase in uptake. The low cost and ease of implementation of this intervention supports further research into its use in routine practice. Our objective was to evaluate the efficacy and acceptability of two interventions designed to increase opportunistic cervical cancer screening. We designed a randomized trial of two interventions additional to usual care. We recruited 17 male general practitioners selected at random from the inner metropolitan region of Sydney, Australia. The patients were 202 women, between 20 and 65 years of age, eligible for a Pap smear. We allocated minimal and maximal interactional interventions to obtain consent for a Pap smear. Our main outcome measure was women's having a Pap smear during the consultation or within one month. We also measured acceptability of interventions to practitioners and women. These were our results: minimal: 55% of women had a Pap smear; maximal: 67% of women had a Pap smear; total when both approaches are combined: 61%. We conclude that brief advice is as effective as maximal persuasion in increasing women's compliance with opportunistic screening in routine consultations. Both interventions were acceptable to women. Practitioners preferred the minimal intervention. We demonstrate opportunistic screening is an effective and acceptable way to encourage women at risk to have a Pap smear. To assess whether an organised programme of prevention including the use of a health promotion nurse noticeably improved recording and follow up of cardiovascular risk factors and cervical smears in a general practice that had access to computerised cell and recall.
                Randomised controlled trial.
                General practice in inner London.
                All 3206 men and women aged 30-64 registered with the practice.
                The intervention group had their risk factors ascertained and followed up by the health promotion nurse and the general practitioner, whereas those in the control group were managed by the general practitioner alone.
                Recording and follow up of blood pressure and cervical smears after three years. Recording of smoking, family history of ischaemic heart disease, and serum cholesterol concentrations were also examined. MEASUREMENTS and
                When the trial was stopped after two years the measurements of blood pressure in the preceding five years were 93% (1511/1620) v 73% (1160/1586) (95% confidence interval for difference 17.5 to 22.7%) for intervention and control groups respectively. For patients with hypertension the figures were 97% (104/107) v 69% (80/116) (18.2 to 38.2%). For women the proportion who had had a cervical smear in the preceding three years were 76% (606/799) v 49% (392/806) (22.5 to 31.9%). Recording of smoking, family history of ischaemic heart disease, and serum cholesterol concentrations was also higher in the intervention group compared with the control group.
                An organised programme, which includes a nurse with specific responsibility for adult prevention, is likely to make an important contribution to recording of risk factors and follow up of those patients with known risks. A randomized controlled study that evaluated a recall system and patient education material by mail in 178 asymptomatic female family practice patients aged 50 to 69 years showed no effect on the proportion of patients who had cancer screening tests (P = .20) and a significant adverse effect on the mean number of tests performed (P = .05) after 4 months. In a subgroup of previous compliers (those who had one or more tests 12 months before the study), however, there was a lower proportion of patients receiving one or more tests (P = .019) with a lower mean number of tests (P = .007) than previous compliers in the control group. Recall strategies for cancer screening tests need to be more extensively studied in the United States before they are routinely adopted in family practice. Our goal was to describe the development and implementation of an intervention on cancer prevention for Latinas in San Diego, Calif. Thirty-six lay community workers ("consejeras") were recruited and trained to conduct educational group sessions. Each consejera recruited approximately 14 peers from the community to participate in the program (total number = 512). Half of the consejeras were randomly assigned to a control group, in which they participated in an equally engaging program entitled "Community Living Skills." Implementation of the intervention was assessed by qualitative and quantitative methods. Preintervention and postintervention self-report information was obtained from project participants on access to health care services, cancer knowledge, preventive measures, and previous cancer-screening examinations. Base-line data suggest that lack of knowledge, costs of cancer-screening tests, and the lack of a regular health care provider are the major obstacles against obtaining cancer-screening tests. Predisposing factors, such as fear and embarrassment, also constitute barriers to getting regular cervical cancer screening. Preliminary analysis indicates that the Por La Vida intervention increases use of cancer-screening tests in comparison to a community living skills control group. Universal access to health care would remove some of the major financial barriers to cancer screening. The Por La Vida program attempts to overcome the substantial barriers by reaching out to low-income Latinas and by providing information regarding the availability, acceptability, and preventive nature of cancer-screening tests. To assess whether providing women with additional information on the pros and cons of screening, compared with information currently offered by the NHS, affects their intention to attend for screening.
                Randomised controlled trial. Participants were randomly assigned to receive either the control, (based on an NHS Cervical Screening Programme leaflet currently used), or the intervention leaflet (containing additional information on risks and uncertainties).
                Three general practices in Birmingham.
                300 women aged 20 to 64 attending the practices during a one month period.
                Intention to attend for screening. Main results: 283 women (94.3%) completed the study. Fewer women in the intervention (79%) than the control group (88%) expressed intention to have screening after reading the information leaflet (difference between groups 9.2%, 95% confidence intervals (CI) 3.2% to 21.7%). The crude odds ratio (OR) and 95% CI was 0.50 (0.26 to 0.97). After adjusting for other factors, the trend persisted (OR 0.60, 95% CI 0.28 to 1.29). Having a previous Pap smear was the only significant predictor of intention to have screening (adjusted OR 2.54, 95% CI 1.03 to 6.21). Subgroup analysis showed no intervention effect in intended uptake between women at higher and lower risk of cervical cancer (p=0.59).
                Providing women with evidence based information on the risks, uncertainties, and the benefits of screening, is likely to deter some, but not differentially those at higher risk. Although cervical cancer is one of the potentially most preventable malignancies, it is still fairly common. In settings with established screening programs, increased compliance is important for future reduction in cervical cancer incidence, but it is presently unclear how this can be effectively achieved.
                We conducted a randomized controlled trial including all 12,240 women invited to organized screening in Sweden. To increase compliance, three successive interventions were tested: (a) modified invitation versus the standard invitation letter, (b) reminder letter to nonattenders after the first intervention versus no reminder letter, and (c) phone reminder to nonattenders after the reminder letter versus no phone reminder. We analyzed the proportion of women attending screening after each intervention and the cumulative proportion after the interventions as well as the cumulative proportions of cytologic abnormalities.
                The modified invitation did not increase attendance compared with the standard invitation letter [difference 1.3% 95% confidence interval (CI) -0.3 to 2.9]. In contrast, a reminder letter increased the proportion of women attending with 9.2% (95% CI 7.9-10.5) compared with women who did not receive a reminder letter, and a phone reminder increased the proportion of women attending with 31.4% (95% CI 26.9-35.9). Combinations of modified invitation, written reminder, and phone reminder almost doubled attendance within 12 months, and the number of detected cytologic abnormalities was more than tripled.
                Simple reminders by mail and phone can drastically increase women's participation in Papanicolaou smear screening and increase the number of detected precursor lesions and thereby save lives. In Australia, Vietnamese women are at greater risk of cervical cancer than other Australian women. To increase their participation in cervical screening, the Vietnamese community was exposed to a media campaign about the advantages of cervical smear screening which was delivered in Vietnamese through Vietnamese newspapers and radio. In addition, 689 Vietnamese (18-67 years) were selected from the electoral roll. They were randomly assigned to either receive a personal letter written in Vietnamese promoting cervical screening, or not. We report on the effect of the letter on smear rates. Being randomised to be sent such a letter was not associated with any increase in screening (relative rate of appropriate screening in the intervention versus the control group was 0.85, 95% CI 0.55-1.3). It is important to carefully evaluate untested health promotion interventions. To determine the effectiveness of a simple call/recall system in improving compliance with cervical cancer screening among women not screened in the previous 3 years.
                Prospective randomized controlled study.
                Two family medicine clinics (1 urban, 1 rural) affiliated with Memorial University of Newfoundland, St. John's.
                A sample of women aged 18-69 years who were listed as patients of the clinics but who had not had a Papanicolaou test (Pap test) within the 3 years before the start of the study. Of 9071 women listed as patients 1360 (15.0%) had not undergone screening in the previous 3 years. A random sample of 650 were selected, 209 of whom were excluded because they had had a hysterectomy, had had a recent Pap test, had moved or had records containing clerical errors. This left 441 women for the study.
                The 221 women in the intervention group were sent a letter asking them to seek a Pap test and a reminder letter 4 weeks later. The 220 in the control group were sent no letters.
                Number of women who had a Pap test within 2 months and 6 months after the first letter was sent.
                Within 2 months, more women in the intervention group than in the control group had been screened (2.8% [5/178] and 1.9% (4/208] respectively). There was also a difference between the overall proportions at 6 months (10.7% [19/178] and 6.3% [13/208] respectively). None of the differences was statistically significant.
                A letter of invitation is not sufficient to encourage women who have never or have infrequently undergone a Pap test to come in for cervical cancer screening. The effectiveness of added recruitment methods such as opportunistic screening by physicians, follow-up by telephone and the offer of a specific appointment should be evaluated. To determine the effects of three different methods of providing health education on the uptake of cervical smear testing among Asian women, and to evaluate the acceptability of different health education materials.
                Prospective cohort study over one year of effects of written materials by post, personal visit to give written materials, and personal visit to show a video on the uptake of smear testing. Techniques included a personally administered questionnaire.
                Leicester, a city with a large Asian population.
                737 randomly selected Asian women aged 18 to 52 who were not recorded on the central cytology laboratory's computer as ever having had a cervical smear test. 159 declined to participate or were not contactable.
                Women were randomised into four groups: visited and shown a video (263), visited and shown a leaflet and fact sheet (219), posted a leaflet and fact sheet (131), not contacted at all (124).
                Cervical smear test recorded on computer within four months after intervention.
                57 (37%, 26% of group) of the women visited and given leaflets and 80 (47%, 30% of group) shown the video attended for cervical smears. Only six (5%) of those who were not contacted and 14 (11%) of those sent leaflets had a smear test during the study.
                Health education interventions increased the uptake of cervical cytology among Asian women in Leicester who had never been tested. Personal visits were most effective irrespective of the health education materials used, but there was some evidence that home viewed videos may be particularly effective in one of the most hard to reach groups: Urdu speaking, Pakistani Moslems. Written translated materials sent by post were ineffective. North American Chinese women have lower levels of Papanicolaou (Pap) testing than other population subgroups. We conducted a randomized controlled trial to evaluate the effectiveness of two alternative cervical cancer screening interventions for Chinese women living in North America.
                Four hundred and eighty-two Pap testing underutilizers were identified from community-based surveys of Chinese women conducted in Seattle, Washington, and Vancouver, British Columbia. These women were randomly assigned to one of two experimental arms or control status. Several Chinese-language materials were used in both experimental arms: an education-entertainment video, a motivational pamphlet, an educational brochure, and a fact sheet. Women in the first experimental group (outreach worker intervention) received the materials, as well as tailored counseling and logistic assistance, during home visits by trilingual, bicultural outreach workers. Those in the second experimental group (direct mail intervention) received the materials by mail. The control group received usual care. Follow-up surveys were completed 6 months after randomization to ascertain participants' Pap testing behavior. All statistical tests were two-sided.
                A total of 402 women responded to the follow-up survey (83% response rate). Of these women, 50 (39%) of the 129 women in the outreach group, 35 (25%) of the 139 women in the direct mail group, and 20 (15%) of the 134 women in the control group reported Pap testing in the interval between randomization and follow-up data collection (P<.001 for outreach worker versus control, P =.03 for direct mail versus control, and P =.02 for outreach worker versus direct mail). Intervention effects were greater in Vancouver than in Seattle.
                Culturally and linguistically appropriate interventions may improve Pap testing levels among Chinese women in North America. To assess the comparative efficacy, by randomised controlled trial, of three interventions designed to encourage "at risk" women to have a Pap smear: an educational pamphlet; letters inviting attendance at a women's health clinic; and letters from physicians.
                Subjects at risk for cervical cancer who had not been adequately screened were identified by a random community survey and randomly allocated to one of the intervention groups or a control group. Six months after intervention implementation, a follow up survey assessed subsequent screening attendance. Self report was validated by comparison with a national screening data base.
                A significantly greater proportion of women (36.9%) within the group receiving a physician letter reported screening at follow up than in any other group (P = 0.012). The variables most strongly predicting screening attendance were: age, perceived frequency of screening required, use of oral contraceptives, and allocation to receive the physician letter intervention.
                The relative efficacy of the GP letter in prompting screening attendance shows that this strategy is worthy of further investigation. There remains a need to examine the barriers to screening for older women, and to develop tailored strategies for this population. The aim was to determine what effect the offer of a cervical smear test when attending for breast screening has on the uptake of cervical and breast screening.
                The study involved randomisation to compare uptake in those women invited for cervical screening in advance with their breast screening invitation (group 1) with those invited for breast screening only and then offered a smear test upon arrival for breast screening (group 2). The main outcome measure was improvement in the uptake of cervical screening among older women without detriment to the breast screening service.
                The study took place at the Northern Hospital in North Manchester.
                Participants were 2131 women aged 50-64 years invited for breast screening at the Northern Hospital in the summer of 1990.
                Overall, 54% of the women who were eligible attended for breast screening, 52% attended from group 1 and 55% from group 2. Of those attending for breast screening, 957 were eligible for cervical screening and 193 (20%) had a smear test. There was a difference in the proportion tested from each group (p < 0.001), 28% had a smear test from group 1 and 13% from group 2. Forty five percent of the 193 had not had a cervical smear for at least five years.
                The cervical screening facility did attract some women who were overdue for a smear test and who might not normally have attended for cervical screening, and there was no evidence to suggest that it had a detrimental effect on the breast screening uptake. An advanced cervical screening invitation seemed preferable to an invitation upon arrival at the breast screening unit. To evaluate a direct mail-out campaign to increase Pap screening rates in women who have not had a test in 48 months.
                Ninety thousand under-screened women were randomised to be mailed a 48-month reminder letter to have a Pap test (n=60,000), or not to be mailed a letter (n=30,000). Differences in Pap test rates were assessed by Kaplan-Meier survival analysis, by chi2 tests of significance between Pap test rates in letter versus no-letter groups, and by proportional hazards regression modelling of predictors of a Pap test with letter versus no-letter as the main study variable. T-tests were conducted on mean time to Pap test to assess whether time to Pap test was significantly different between the intervention and control groups.
                After 90 days following each mail-out, Pap test rates in the letter group were significantly higher than in the non-letter group, by approximately two percentage points. After controlling for potential confounders, the hazard ratio of a Pap test within 90 days of a mail-out in the letter group was 1.5 compared with 1.0 in the no-letter group. Hazard ratios of having a Pap test within 90 days decreased significantly with time since last Pap test (p<0.0001); were significantly higher than 1.0 for most non-metropolitan areas of NSW compared with metropolitan areas; and increased significantly with age (p<0.0001). Pap test hazard ratios were not associated with socio-economic status of area of residence, but the hazard ratio was significantly higher than 1.0 if the reminder letter was sent after the Christmas/New Year break. No significant differences in mean time to Pap test were found between the letter and no-letter groups.
                Being sent a reminder letter is associated with higher Pap testing rates in under-screened women. In a randomized trial three ways of increasing rates of cervical screening were compared for women attending a family medicine center. Working from computerized medical records, 1,587 women aged 18 to 35 years who were overdue for a screening test were included in the study. In a control group, no formal method was used to encourage patients to attend for screening, and 13.7 percent obtained a test within the trial year. In one intervention group the physician was issued a message identifying those women visiting the center for a routine appointment who were due for screening; 16.1 percent were screened. Sending a letter to patients in a second group yielded a 25.9 percent compliance rate. In a third group the practice nurse called patients on the telephone to advise them to obtain the test, and 20.0 percent complied. Reminders issued to the physician provide a low-cost, opportunistic approach to reach women who happen to visit the practice, but this approach should be supplemented by telephoning or sending a letter to those women who do not attend regularly. Attendance level has been identified as a major determinant of cost-effectiveness of organized screening programs. We tested the effectiveness of 4 different invitation systems in the context of an organized population screening program for cervical and breast cancer.
                Women eligible for invitation--8385 for cervical and 8069 for breast cancer screening--listed in the rosters of 43 and 105 general practitioners (GP), respectively, who had accepted to collaborate in the program, were randomized to 4 invitation groups: Group A--letter signed by the GP, with a prefixed appointment; Group B--open-ended invitation, signed by the GP, prompting women to contact the screening center to arrange an appointment; Group C--letter (same as for group A), signed by the program coordinator, with a prefixed appointment; Group D--extended letter (highlighting the benefits of early cancer detection) signed by the GP, with a prefixed appointment. Assignment to the interventions was based on a randomized block design (block=GP).
                Assuming Group A as the reference, the overall compliance with cervical cancer screening was reduced by 39% in Group B (RR=0.61; 95% CI, 0.56-0.68) and by 14% in Group C (RR=0.86; 95% CI, 0.78-0.93); no difference was observed for Group D (RR=1.03; 95% CI, 0.95-1.1). The response pattern was similar for breast screening (Group B: RR=0.71; 95% CI, 0.65-0.76; Group C: RR=0.87; 95% CI, 0.81-0.94; Group D: RR=1.01; 95% CI, 0.94-1.08).
                Personal invitation letters signed by the woman's GP, with preallocated appointments, induce a significant increase in compliance with screening. Efficiency can be ensured through the adoption of overbooking, provided that attendance levels are regularly monitored. While reminders can promote cancer screening in primary care, little is known about the potential interaction between multiple reminders.
                We conducted a randomized controlled trial to compare the effect of combined Pap smear plus mammogram reminders and mammogram-only reminders among 2471 women 40 years of age or older enrolled in a health maintenance organization serving a predominantly Medicaid-eligible population. Reminders included both a mailed letter for the woman and a medical record prompt.
                Intervention assignment was unassociated with differences in rates of visitation to family medicine or internal medicine or completion of mammography during the study year. Compared to women assigned to mammogram-only reminder treatment, those assigned to the combined Pap smear plus mammogram reminder intervention were more likely to visit a gynecologist (34% compared to 29%, adjusted odds ratio = 1.33, 95% confidence interval 1.08-1.63) and to complete a Pap smear (30% compared to 23%, adjusted odds ratio = 1.39, 95% confidence interval 1.07-1.89).
                In the study setting, the addition of Pap smear to mammography reminders has a procedure-specific effect, increasing gynecology visits and Pap smear use while neither increasing nor decreasing other primary care visits or mammography. We find no evidence of reinforcement or competition between these reminders. Health risk appraisal (HRA) remains one of the most widely used health promotion tools despite only equivocal evidence for its effectiveness. Theories of behavior change predict conventional HRA's ineffectiveness because risk information alone is seldom sufficient to change complex behaviors. In this study, a randomized trial compared the effects of feedback from an enhanced HRA with a typical HRA and a control group among adult patients from eight family medicine practices. The enhanced HRA assessed behavior-specific psychosocial factors and provided patients with computer-generated, individually-tailored behavior change information in addition to typical HRA risk feedback. Changes in seven behaviors were assessed at a 6 month follow-up. Overall, patients receiving enhanced HRA feedback were 18% more likely to change at least one risk behavior than were patients receiving typical HRA feedback or no feedback (OR = 1.18, 95% CI = 1.00, 1.39). The enhanced HRA feedback appeared to promote changes in cholesterol screening, dietary fat consumption and physical activity, but not in smoking, seat belt use, mammography and Pap smears. We conclude that the addition of theory-based, individually-tailored behavior change information may improve the effectiveness of HRA. To discover whether systematic methods of call and recall are more effective than a non-systematic method and to see which of the two systematic methods was more effective.
                Prospective randomised controlled trial over a year.
                One group general practice.
                416 Women over 35 eligible for a smear test who had never had a cervical smear test or in whom a smear test was overdue (previous test more than five years before).
                One group received written invitations to have a smear taken. The second group had their notes tagged so that the doctor would remind them (when they attended for another reason) to have a smear test. No special intervention was made in the third group.
                Performance of a cervical smear test during the year of the study.
                32% (45/140) of the screened group, 27% (39/142) of the tagged group, and 15% (20/134) of the control group had a smear test during the year. The percentage of women having a smear test in the screened group was not significantly different from that in the tagged group, but the percentages in the two groups were significantly different from that in the control group. Whether a woman had had a previous smear test significantly affected the uptake of the invitation to have a smear test independently of the method of invitation.
                The systematic methods of call and recall were more effective than a non-systematic method. There was no significant difference between the two systematic methods (sending letters or tagging the notes) at one year. We sought to promote cervical cancer screening among Vietnamese American women in Santa Clara County, Calif.
                In 2001-2004, we recruited and randomized 1005 Vietnamese American women into 2 groups: lay health worker outreach plus media-based education (combined intervention) or media-based education only. Lay health workers met with the combined intervention group twice over 3 to 4 months to promote Papanicolaou (Pap) testing. We used questionnaires to measure changes in awareness, knowledge, and Pap testing.
                Testing increased among women in both the combined intervention (65.8% to 81.8%; P<.001) and media-only (70.1% to 75.5%; P<.001) groups, but significantly more in the combined intervention group (P=.001). Among women never previously screened, significantly more women in the combined intervention group (46.0%) than in the media-only group (27.1%) obtained tests (P<.001). Significantly more women in the combined intervention group obtained their first Pap test or obtained one after an interval of more than 1 year (became up-to-date; 45.7% to 67.3%, respectively; P<.001) than did those in the media-only group (50.9% to 55.7%, respectively; P=.035).
                Combined intervention motivated more Vietnamese American women to obtain their first Pap tests and to become up-to-date than did media education alone. We conducted a randomized controlled trial to determine if an in-home educational intervention conducted by lay health workers (LHWs) could increase adherence among low-income, inner-city, African-American women to breast and cervical cancer screening schedules.
                We recruited 321 African-American women from diverse inner-city sources. After baseline interviews, they were randomly assigned to either the intervention (n = 163) or the control (n = 158) group. Those in the intervention group were visited in their homes up to three times by LHWs who provided a culturally sensitive educational program that emphasized the need for screening.
                Ninety-three (93) women in the intervention group and 102 in the control group completed the postintervention interview. For Pap smears, the increase in screening was similar in both groups. For clinical breast exams (CBEs), however, there was a modest increase in the intervention group. The improvement was greatest for mammography, for which there was a 10% to 12% increase. Among women who were not on recommended schedules at baseline, the improvement was substantial and greater in the intervention group.
                LHWs' intervention appeared to improve the rate at which inner-city women obtained CBEs and mammograms, but had no effect on Pap smears. A high attrition rate weakened our ability to make conclusive statements about the exact impact of the intervention. A culturally appropriate women's health service was established at an Aboriginal community-controlled health service in Darwin in 1994. An initial file audit found that 48% of included women had ever been screened with a Pap smear and 37% of women were considered to have been adequately screened. The enhancement of opportunistic screening by file tagging had a modest effect on screening coverage over a 12-month period for women who attended the health service. The proportion of these women who were adequately screened increased from 43% to 48% and of those ever screened increased from 54% to 62%. A randomised trial of recruitment interventions including personal approach, letter and control groups was subsequently performed for women for whom Pap smears were overdue or not recorded. The impact of both interventions on the number of Pap smears performed was low, with 7% of women in the personal approach group, 2% of women in the letter group and no women in the control group having Pap smears during the three-month follow-up period. Low rates of abnormalities were observed for women having Pap smears over a two-year period. The minimal effect of a formal reminder system and letters at this urban Aboriginal health service has resulted in a re-orientation of activities towards strengthening opportunistic screening and the continued promotion of Pap smears in a range of clinic and community settings. It is important to place Pap smear screening in the context of other social, economic and health priorities for Aboriginal women and health workers. nan We conducted a 4-year randomized study in a community health center that serves primarily low income Blacks in Durham, North Carolina. Patients (1318 at baseline) were assigned randomly to one of three study groups: provider prompting intervention alone, provider prompting and tailored print materials or the previous group and tailored telephone counseling. The purpose of the study was to determine whether increasingly intensive, tailored print and telephone interventions also were increasingly effective in promoting adherence to mammograms, Pap tests and overall cancer screening compliance. Thus, the combination of tailored print interventions (print and telephone) should have been more effective than the provider prompting intervention alone, or the print intervention and prompting combination. This is one of the few studies to examine a measure of overall cancer screening compliance and to assess the benefit of combinations of tailored interventions in promoting adherence to cancer screening. Patients gave extremely high ratings to the interventions. At the bivariate level, we found a significant effect of the most intensive group (provider prompting intervention, tailored print communications and tailored telephone counseling) on Pap test compliance (P = 0.05) and borderline significance at the multivariate level (P = 0.06) as well on overall screening compliance (P = 0.06). There was not a significant effect on mammography, probably because a majority of the patients were receiving regular mammograms. We also found some important subgroup differences. For example, a larger proportion of women reported Pap tests in the tailored print and counseling group when they believed the materials were 'meant for me.' These results show that a combination of tailored interventions may have potential for reaching the women who have too often been labeled the 'hard to reach.' This study examined the effect of three interventions for encouraging women to have a Pap smear in a general practice: tagging the medical record to remind the doctor to offer a Pap smear, sending an invitation to make an appointment for a Pap smear, and sending an invitation with an appointment to attend for a Pap smear at a special screening clinic staffed by women. The study took place in a university general practice at Lockridge, near Perth. A computerised practice age-sex register provided 2139 women in the age range 36 to 69 inclusive. Of these, 757 were eligible for inclusion in the study and were allocated randomly to one of three intervention groups or a control group. In total, 177 women had a Pap smear during the study. Significantly more Pap smears were taken for the appointment-letter and letter-only groups than the control group (odds ratio (OR) 2.13, 95% confidence interval (CI) 1.34 to 3.57, and OR 1.67, CI 1.01 to 2.77 respectively), but there was no significant difference between the tagged-notes and the control groups. Women who attended the screening clinic rated the experience positively. Attendance, however, was inadequate for the clinic's viability in a private practice. The purposes of the study were (1). to assess the cost-effectiveness of three interventions to deliver breast and cervical cancer screening to women unscreened for >or=3 years and (2). to determine the relation of an invasive cervical cancer diagnosis to the interval since the last true screening test.
                In a randomized trial, women were randomly assigned to (1). usual care, (2). letter plus follow-up letter, (3). letter plus follow-up phone call, (4). phone call plus follow-up phone call. Screening within 12 weeks was the outcome. A 5-year retrospective review of cervical cancer cases and screening histories was done.
                The 8% of women not screened for >or=5 years had 62% of the invasive cervical cancer cases. Mammography outreach led to screening in 10%, 24%, 51%, and 50% of controls, letter/letter, letter/phone, and phone/phone interventions groups, respectively. Cervical cancer screening outreach led to screening in 17%, 22%, 54%, and 50% of the respective groups. Letter reminders alone produced fewer tests at substantially higher costs than did personalized telephone notification.
                For cervical cancer, only 1 person in 12 was not screened in the preceding 5 years, but these accounted for nearly two thirds of invasive cancers. Aggressive outreach to the rarely screened is an important part of screening programs. Letter reminder, followed by a telephone appointment call, was the most cost-effective approach to screening rarely screened women. Lack of accurate information on prior hysterectomy adds substantial unnecessary costs to a screening reminder program. Measures to increase attendance rate in cervical screening programmes have been suggested, but few have been evaluated in terms of value for money. The aim of this study was to describe the cost-effectiveness of a resource-intensive intervention to promote attendance at cervical screening among women with no registered cervical smear during the last 5 years. Among all 56 644 women (28-65 years) in Kalmar County, January 2004, a total of 6565 women had no registered cervical smear during the last 5 years. From this population, 400 women were randomly selected to a study group and another 400 women to a control group. The intervention was composed of a variety of efforts intended to promote attendance at cervical screening. We included, for example, all costs for identifying the women, sending out invitation letters, making phone calls and helping to make arrangements. Data on registered cervical smears at follow-up were collected from a data register within 1 year. In the study group, 118 women had a registered cervical smear compared with 74 in the control group (P=0.000). In the study group, the cost per cervical smear taken was 66.87 euro compared with 16.63 euro in the ordinary screening programme. The incremental cost per additional registered cervical smear was calculated at 151.36 euro in an area with high coverage, efforts to promote attendance at cervical screening were related to high costs per extra cervical smear gained and is not considered as reasonable from a cost-effectiveness perspective. Despite its effectiveness as a method of controlling cervical carcinoma, the use of Pap smear testing remains incomplete, and its promotion in the primary care setting provides an important opportunity for intervention.
                The authors conducted a randomized controlled trial that involved three sites of a health maintenance organization (HMO) serving an urban minority population. Their aim was to evaluate the impact of reminders given to patients and physicians on site visitation by patients and Pap smear use. Eligible women (n=5801) were randomly assigned to 1 of 4 intervention combinations (in which reminders were given to either the patient or the physician, to both, or to neither). If they were ineligible for patient reminder intervention, patients were randomized only to physician reminder intervention (the presence or absence of it). The letter of reminder mailed to the patient invited women due for Pap smears to visit the HMO site, and the reminder for physicians was a medical record notice that a Pap smear was due. Logistic and survival analyses were used to investigate the correlation of intervention status with visitation, interval of time to a visit, and Pap smear use.
                In the primary intent-to-treat analysis, there was no significant effect of either patient or physician reminder interventions on rates of visitation or Pap smear completion. The secondary efficacy analyses demonstrated no overall effect of either patient or physician reminders, but effects among subgroups of women at individual HMO sites were noted. At Site 3, there was an apparent increase in time to the next visit among the subgroup of women with a chronic illness (16 weeks with intervention vs. 9 weeks without). With the physician reminder, the odds that a Pap smear would be given during the study year were increased among women without a previous Pap smear at Site 1 (adjusted odds ratio=1.39) and those with a chronic illness at Site 2 (adjusted odds ratio=3.38).
                Reminders given to patients and physicians had a limited impact on visitation by patients to the HMO sites or Pap smear completion. Although some subgroups of women may benefit, the authors also observed a possibly unfavorable impact among other subgroups. These results emphasize the importance of identifying more effective interventions, targeting them to women most likely to benefit, and not overlooking the possibility that preventive intervention will have an unanticipated adverse effect. Despite an emerging consensus on appropriate preventive services, a minority of patients receive them. A study was undertaken to assess the impact of computer-generated reminders to adult patients, their physicians, or both patients and physicians on adherence to five recommended preventive services: cholesterol measurements, fecal occult blood testing, mammography, Papanicolaou smears, and tetanus immunization. During the academic year 1988-1989, all 7397 adult patients and their 49 physicians in a university family medicine clinical practice were randomized by practice group into one of four study groups: control, physician reminders, patient reminders, and both physician and patient reminders. Adherence was defined in community-oriented terms: the percentage of patients within each group who had received the preventive service in the recommended interval. During the study period, adherence to four of the five preventive services increased significantly, with the largest increases in the physician and patient reminder group: cholesterol measurements increased from 19.5% to 38.1%, fecal occult blood testing 9.3% to 27.0%, mammography 11.4% to 27.1%, and tetanus immunization 23.4% to 35.4% (for each increase, P less than .0001, McNemar's chi-square test). In general, increases were greater in blacks and in patients with any form of insurance coverage. Computer-based physician and patient reminder systems have great promise of improving adherence to preventive services in primary care settings. Successful cervical cancer prevention depends on reaching, screening and treating women with pre-invasive disease. We aimed to evaluate the effectiveness of two media interventions-a photo-comic and a radio-drama-in increasing cervical screening uptake. A randomized controlled trial compared a photo-comic on cervical cancer screening with a placebo comic. One month after the comics were distributed a radio-drama paralleling the photo-comic was broadcast on the community radio station and a retrospective evaluation was carried out. The trial was set in Khayelitsha, a peri-urban squatter community near Cape Town, South Africa. A random sample consisted of 658 women between the ages of 35 and 65 years, from a stratified sample of census areas. The main outcome measure was self-reported cervical screening uptake 6 months after distribution of the comics. Seven percent (18 of 269) of women who received the intervention photo-comic reported cervical screening during the 6 months follow-up, compared with 6% (25 of 389) of controls (P = 0.89). Women who recalled hearing the radio-drama were more likely to report attending screening (nine of 53, 17%) than those who did not (19 of 429, 4%; P < 0.001). We conclude that the photo-comic was ineffective in increasing cervical screening uptake in this population. The radio-drama may have had more impact, but only a minority of women recalled being exposed to it. Future research must concentrate not only on achieving high level of exposure to health messages, but also on investigating the links between exposure and action. nan In a randomized experiment, women (N = 441) watched either a loss- or gain-framed video emphasizing the prevention or detection functions of the Pap test to test the hypothesis that loss- and gain-framed messages differentially influence health behaviors depending on the risk involved in performing the behavior. As predicted, loss-framed messages emphasizing the costs of not detecting cervical cancer early (a risky behavior) and gain-framed messages emphasizing the benefits of preventing cervical cancer (a less risky behavior) were most persuasive in motivating women to obtain a Pap test.
There is evidence to support the use of invitation letters to increase the uptake of cervical screening. There is limited evidence to support educational interventions but it is unclear what format is most effective. The majority of the studies are from developed countries and so the relevance to developing countries is unclear.
