Adverse drug-related events are common in the elderly, and inappropriate prescribing is a preventable risk factor. Our objective was to determine whether inappropriate prescribing could be reduced when primary care physicians had computer-based access to information on all prescriptions dispensed and automated alerts for potential prescribing problems.
                We randomly assigned 107 primary care physicians with at least 100 patients aged 66 years and older (total 12 560) to a group receiving computerized decision-making support (CDS) or a control group. Physicians in the CDS group had access to information on current and past prescriptions through a dedicated computer link to the provincial seniors' drug-insurance program. When any of 159 clinically relevant prescribing problems were identified by the CDS software, the physician received an alert that identified the nature of the problem, possible consequences and alternative therapy. The rate of initiation and discontinuation of potentially inappropriate prescriptions was assessed over a 13-month period.
                In the 2 months before the study, 31.8% of the patients in the CDS group and 33.3% of those in the control group had at least 1 potentially inappropriate prescription. During the study the number of new potentially inappropriate prescriptions per 1000 visits was significantly lower (18%) in the CDS group than in the control group (relative rate [RR] 0.82, 95% confidence interval [CI] 0.69-0.98), but differences between the groups in the rate of discontinuation of potentially inappropriate prescriptions were significant only for therapeutic duplication by the study physician and another physician (RR 1.66, 95% CI 0.99-2.79) and drug interactions caused by prescriptions written by the study physician (RR 2.15, 95% CI 0.98-4.70).
                Computer-based access to complete drug profiles and alerts about potential prescribing problems reduces the rate of initiation of potentially inappropriate prescriptions but has a more selective effect on the discontinuation of such prescriptions. Poorly executed transfers of older patients from hospitals to long-term care facilities carry the risk of fragmentation of care, poor clinical outcomes, inappropriate use of emergency department services, and hospital readmission.
                This study was conducted to assess the impact of adding a pharmacist transition coordinator on evidence-based medication management and health outcomes in older adults undergoing first-time transfer from a hospital to a long-term care facility.
                This randomized, single-blind, controlled trial enrolled hospitalized older adults awaiting transfer to a long-term residential care facility for the first time. Patients were randomized either to receive the services of the pharmacist transition coordinator (intervention group) or to undergo the usual hospital discharge process (control group). The intervention included medication-management transfer summaries from hospitals, timely coordinated medication reviews by accredited community pharmacists, and case conferences with physicians and pharmacists. The primary outcome was the quality of prescribing, measured using the Medication Appropriateness Index (MAI). Secondary outcomes were emergency department visits, hospital readmissions, adverse drug events, falls, worsening mobility, worsening behaviors, increased confusion, and worsening pain.
                One hundred ten older adults (67 women, 43 men; mean [SD] age, 82.7 [6.4] years) were recruited from 3 metropolitan hospitals and assigned to 85 metropolitan long-term care facilities. Fifty-six patients were randomized to the intervention group and 54 to the control group; 44 patients in each group were evaluable at 8-week follow-up. There were no significant differences in baseline characteristics between treatment groups, with the exception of the number of medications discontinued during hospitalization: a mean of 1.1 more drugs was discontinued in the control group compared with the intervention group (P = 0.011). The majority of patients (35 [62.5%] in the intervention group, 41 [76.0%] in the control group) changed physicians as part of the transition to a long-term care facility. At 8-week follow-up, there was no change in MAI from baseline in the intervention group, whereas it had worsened in the control group (mean [95% CI], 2.5 [1.4-3.7] vs 6.5 [3.9-9.1], respectively; P = 0.007). Patients who received the intervention and were alive at follow-up exhibited a significant protective effect of the intervention against worsening pain (relative risk ratio [95% CI], 0.55 [0.32-0.94]; P = 0.023) and hospital usage (i.e., the combination of emergency department visits and hospital readmissions) (0.38 [0.15-0.99]; P = 0.035), but did not differ from control patients in terms of adverse drug events (1.05 [0.66-1.68]), falls (1.19 [0.71-1.99]), worsening mobility (0.39 [0.13-1.15]), worsening behaviors (0.52 [0.25-1.10]), or increased confusion (0.59 [0.28-1.22]). When data for patients who had died were included, the intervention had no effect on hospital usage in all patients (0.58 [0.28-1.21]).
                Older people transferring from hospital to a long-term care facility are vulnerable to fragmentation of care and adverse events. In this study, use of a pharmacist transition coordinator improved aspects of inappropriate use of medicines across health sectors. To determine if inpatient or outpatient geriatric evaluation and management, as compared with usual care, reduces adverse drug reactions and suboptimal prescribing in frail elderly patients.
                The study employed a randomized 2 x 2 factorial controlled design. Subjects were patients in 11 Veterans Affairs (VA) hospitals who were > or =65 years old and met criteria for frailty (n = 834). Inpatient geriatric unit and outpatient geriatric clinic teams evaluated and managed patients according to published guidelines and VA standards. Patients were followed for 12 months. Blinded physician-pharmacist pairs rated adverse drug reactions for causality (using Naranjo's algorithm) and seriousness. Suboptimal prescribing measures included unnecessary and inappropriate drug use (Medication Appropriateness Index), inappropriate drug use (Beers criteria), and underuse.
                For serious adverse drug reactions, there were no inpatient geriatric unit effects during the inpatient or outpatient follow-up periods. Outpatient geriatric clinic care resulted in a 35% reduction in the risk of a serious adverse drug reaction compared with usual care (adjusted relative risk = 0.65; 95% confidence interval: 0.45 to 0.93). Inpatient geriatric unit care reduced unnecessary and inappropriate drug use and underuse significantly during the inpatient period (P <0.05). Outpatient geriatric clinic care reduced the number of conditions with omitted drugs significantly during the outpatient period (P <0.05).
                Compared with usual care, outpatient geriatric evaluation and management reduces serious adverse drug reactions, and inpatient and outpatient geriatric evaluation and management reduces suboptimal prescribing, in frail elderly patients. efficient strategies are needed to provide specialist advice in nursing homes to ensure quality medical care. We describe a case conference intervention involving a multidisciplinary team of health professionals.
                to evaluate the impact of multidisciplinary case conferences on the appropriateness of medications and on patient behaviours in high-level residential aged care facilities.
                cluster-randomised controlled trial.
                ten high-level aged care facilities.
                154 residents with medication problems and/or challenging behaviours were selected for case conference by residential care staff.
                two multidisciplinary case conferences involving the resident's general practitioner, a geriatrician, a pharmacist and residential care staff were held at the nursing home for each resident.
                outcomes were assessed at baseline and 3 months. The primary outcome was the Medication Appropriateness Index (MAI). The behaviour of each resident was assessed via the Nursing Home Behaviour Problem Scale.
                45 residents died before follow-up. Medication appropriateness improved in the intervention group [MAI mean change 4.1, 95% confidence interval (CI) 2.1-6.1] compared with the control group (MAI mean change 0.4, 95% CI -0.4-1.2; P < 0.001). There was a significant reduction in the MAI for benzodiazepines (mean change control -0.38, 95% CI -1.02-0.27 versus intervention 0.73, 95% CI 0.16-1.30; P = 0.017). Resident behaviours were unchanged after the intervention and the improved medication appropriateness did not extend to other residents in the facility.
                multidisciplinary case conferences in nursing homes can improve care. Outreach specialist services can be delivered without direct patient contact and achieve improvements in prescribing. To evaluate the effect of pharmaceutical care provided in addition to acute Geriatric Evaluation and Management (GEM) care on the appropriateness of prescribing.
                Randomized, controlled trial, with the patient as unit of randomization.
                Acute GEM unit.
                Two hundred three patients aged 70 and older.
                Pharmaceutical care provided from admission to discharge by a specialist clinical pharmacist who had direct contacts with the GEM team and patients.
                Appropriateness of prescribing on admission, at discharge, and 3 months after discharge, using the Medication Appropriateness Index (MAI), Beers criteria, and Assessing Care of Vulnerable Elders (ACOVE) underuse criteria and mortality, readmission, and emergency visits up to 12 months after discharge.
                Intervention patients were significantly more likely than control patients to have an improvement in the MAI and in the ACOVE underuse criteria from admission to discharge (odds ratio (OR)=9.1, 95% confidence interval (CI)=4.2-21.6 and OR=6.1, 95% CI=2.2-17.0, respectively). The control and intervention groups had comparable improvements in the Beers criteria.
                Pharmaceutical care provided in the context of acute GEM care improved the appropriate use of medicines during the hospital stay and after discharge. This is an important finding, because only limited data exist on the effect of various strategies to improve medication use in elderly inpatients. The present approach has the potential to minimize risk and improve patient outcomes. In response to burgeoning drug costs, North Carolina (NC) Medicaid encouraged pharmacists and prescribers to develop collaborative programs to reduce drug expenditures. One of these programs, the North Carolina Polypharmacy Initiative, was a focused drug therapy management intervention aimed at reducing polypharmacy in nursing homes. This intervention targeted patients with more than 18 prescription fills in 90 days, beginning in November 2002. These patients were believed to have a high likelihood of experiencing potential drug therapy problems (PDTPs). Consultant pharmacists were asked to utilize profiles displaying alerts generated from pharmacy claims to guide interventions in addition to usual-care drug regimen reviews. The pharmacists documented their reviews, recommendations, and resulting changes in drug therapy. Our objectives were to determine (1) the persistence of PDTP alerts following interventions by consultant pharmacists and (2) the impact of these interventions on patient drug costs from a payer perspective.
                A before-after study with comparison group design was used. Medicaid prescription claims data were compared for the 90-day periods prior to the intervention (June-August 2002) and following the intervention (March-June 2003). The 90-day post-intervention period allowed for 2 to 3 follow-up prescriptions and reduced the drop-out rate. The 5 categories of potential problem alerts included potentially inappropriate medications (Beers criteria), substitution opportunity for a lower-cost drug, 16 drugs or drug classes with specific quality improvement opportunities (Clinical Initiatives list), therapeutic duplication, and length of drug therapy evaluation.
                A total of 253 nursing homes, involving 110 consultant pharmacists and 6,344 patients, were in the intervention arm, with 5,160 patients (81.3%) remaining at the end of the follow-up period. At baseline, study-group patients used an average of 9.7 prescriptions per month, costing the NC Medicaid program 517 US dollars per patient per month (PPPM). There were 6,360 recommendations offered for 3,400 patients, or an average of 1.87 recommendations per patient. Physicians concurred with 59.8% (3,801 of 6,360) of all recommendations to change drug therapy, about half involving a switch to a lower-cost drug. Two of 5 alert categories had significant (P <0.01) reductions in alert persistence: -10.8% for the study group versus -0.7% for the comparison group for the Clinical Initiatives list and -29.7% for the study group versus -14.1% in the comparison group for the drug substitution opportunity. Median drug costs per patient in the study group decreased by 12.14 US dollars (-0.92%), from 1,329.46 US dollars to 1,317.32 US dollars, and increased in the comparison group by 44.98 US dollars (3.35%), from 1,341.25 US dollars to 1,386.23 US dollars, creating a relative cost reduction of 57.12 US dollars per patient in the 3-month follow-up period, or 19.04 US dollars PPPM.
                A supplemental program of medication reviews for nursing home patients targeted by high drug utilization resulted in a reduction in the persistence of PDTP alerts and was cost beneficial based solely on drug cost savings. This intervention may be a model for future medication therapy management services provided by prescription drug plans under Medicare Part D for patients in long-term-care settings and possibly ambulatory patients. To evaluate the effect of sustained clinical pharmacist interventions involving elderly outpatients with polypharmacy and their primary physicians.
                Randomized, controlled trial of 208 patients aged 65 years or older with polypharmacy (> or = 5 chronic medications) from a general medicine clinic of a Veterans Affairs Medical Center. A clinical pharmacist met with intervention group patients during all scheduled visits to evaluate their drug regimens and make recommendations to them and their physicians. Outcome measures were prescribing appropriateness, health-related quality of life, adverse drug events, medication compliance and knowledge, number of medications, patient satisfaction, and physician receptivity.
                Inappropriate prescribing scores declined significantly more in the intervention group than in the control group by 3 months (decrease 24% versus 6%, respectively; P = 0.0006) and was sustained at 12 months (decrease 28% versus 5%, respectively; P = 0.0002). There was no difference between groups at closeout in health-related quality of life (P = 0.99). Fewer intervention than control patients (30.2%) versus 40.0%; P = 0.19) experienced adverse drug events. Measures for most other outcomes remained unchanged in both groups. Physicians were receptive to the intervention and enacted changes recommended by the clinical pharmacist more frequently than they enacted changes independently for control patients (55.1% versus 19.8%; P <0.001).
                This study demonstrates that a clinical pharmacist providing pharmaceutical care for elderly primary care patients can reduce inappropriate prescribing and possibly adverse drug effects without adversely affecting health-related quality of life. The high cost and undesirable consequences of polypharmacy are well-recognized problems among elderly long-term care (LTC) residents. Despite the implementation of the 1987 Omnibus Budget Reconciliation Act, which requires pharmacist review of drug regimens in this setting, medical and drug costs for LTC residents have continued to increase.
                This study evaluates the North Carolina Long-Term Care Polypharmacy Initiative, a large-scale medication therapy management program (MTMP) that combined drug utilization review activities with drug regimen review techniques.
                This was a prospective records-based study that used a difference-in-difference model with both historical and nonintervention group controls. To ensure equivalence among subjects, propensity scoring was used to match study subjects from participating LTC facilities with comparison subjects from nonparticipating facilities. Residents with interventions were grouped for analysis by intervention type-retrospective only, prospective only, or dual type (residents with both prospective and retrospective interventions)-and by intervention stage-review, recommendation, and drug change-plus an all-inclusive "all types" grouping that aggregated groups by intervention type, for a total of 10 total cohorts.
                In the overall population of 5255 study subjects identified, a US $21.63 per member per month drug-cost savings was observed. Although only 1 of 10 cohorts had a change in the number of drug fills, substantial reductions in 2 of 5 types of drug alerts were observed in all 10 cohorts. A reduction in the relative risk for hospitalization (0.84 [95% CI, 0.71-1.00]) was observed in the cohort of residents receiving a retrospective review.
                This Initiative suggests that an MTMP can be quickly launched in a large number of LTC facility residents to produce monetary drug-cost savings and improved health outcomes. Additionally, the evaluation of this program illustrates the utility of using propensity scoring techniques to target future intervention groups in a cost-effective manner. The effect of pharmaceutical care on the prevention, detection, and resolution of medication-related problems in high-risk patients in a rural community was studied. Adult patients who received care at clinics in a medically underserved area of Alabama and who were identified as being at high risk of medication-related adverse events were randomly assigned to a control group or an intervention group. The control group received standard medical care, and the intervention group received pharmaceutical care, including a medical record review, a medication history review, pharmacotherapeutic evaluation, and patient medication education and monitoring over a one-year period. A total of 69 patients completed the study (33 in the intervention group and 36 in the control group). The percentage of patients responding to hypertension, diabetes, dyslipidemia, and anticoagulation therapy increased significantly in the intervention group and declined in the control group. Ratings for inappropriate prescribing improved in all 10 domains evaluated in the intervention group but worsened in 5 domains in the control group. There were no significant differences between the groups at 12 months in health-related quality of life or medication misadventures. Medication compliance scores improved in the intervention group but not in the control group. Medication knowledge increased in the intervention group and decreased in the control group. Pharmaceutical care in a rural, community-based setting appeared to reduce inappropriate prescribing, enhance disease management, and improve medication compliance and knowledge without adversely affecting health-related quality of life. It has been cited that the management of congestive heart failure (CHF) requires a multidisciplinary approach; however, the role of the pharmacist has not been extensively studied. The roles for pharmacists are changing to meet the long term needs of patients in the community setting, including patients with CHF.
                To evaluate the effect of a pharmacist on the appropriateness of medications taken by patients in the heart function clinic using the Medication Appropriateness Index (MAI) and to measure the effect of a pharmacist on the patients' response to the pharmacist's interventions using the Purdue Directive Guidance (DG) scale.
                Eighty patients attending the heart function clinic at The University Health Network, Toronto General Hospital Toronto, Ontario were randomly assigned to an intervention group that received pharmacist services or a nonintervention group that received usual care from the clinic staff. Patients were assessed at baseline and at one-month follow-up.
                The change in MAI score from baseline was 0.74 and 0.49 for the intervention and nonintervention groups, respectively (P=0.605). The change in DG survey results was 9.97 and 1.00 for the intervention and nonintervention groups, respectively (P<0.001). The intervention group improved significantly in all components of the DG survey, especially those pertaining to feedback and goal setting.
                A benefit was demonstrated for 'directive guidance' of patients, in the form of education and goal setting as shown by positive survey results.
It is unclear if interventions to improve appropriate polypharmacy, such as pharmaceutical care, resulted in a clinically significant improvement; however, they appear beneficial in terms of reducing inappropriate prescribing and medication-related problems.
