Real-time, evidence-based medicine instruction: a randomized controlled trial in a neonatal intensive care unit. Educational workshop improved information-seeking skills, knowledge, attitudes and the search outcome of hospital clinicians: a randomised controlled trial. Effectiveness and efficiency of a literature search strategy to answer questions on the etiology of occupational diseases: a controlled trial.
The study assesses potential for improving residents' evidence-based medicine searching skills in MEDLINE through real-time librarian instruction.
                Ten residents on a rotation in a neonatal intensive care unit participated.
                Residents were randomized into an instruction and a non-instruction group. Residents generated questions from rounds and searched MEDLINE for answers. Data were collected through observation, search strategy analysis, and surveys. Librarians observed searches and collected data on questions, searching skills, search problems, and the test group's instruction topics. Participants performed standardized searches before, after, and six-months after intervention and were scored using a search strategy analysis tool (1 representing highest score and 5 representing lowest score). Residents completed pre- and post-intervention surveys to measure opinions about MEDLINE and search satisfaction.
                Post-intervention, the test group formulated better questions, used limits more effectively, and reported greater confidence in using MEDLINE. The control group expressed less satisfaction with retrieval and demonstrated more errors when limiting. The test and control groups had the following average search scores respectively: 3.0 and 3.5 (pre-intervention), 3.3 and 3.4 (post-intervention), and 2.0 and 3.8 (six-month post-intervention).
                Data suggest that measurable learning outcomes were achieved. Residents receiving instruction improved and retained searching skills six-months after intervention. A double-blind randomised controlled trial was conducted on a group of Hong Kong hospital clinicians. The objective was to test if a three-hour educational workshop (with supervised hands-on practice) is more effective (than no training) to improve clinical question formulation, information-seeking skills, knowledge, attitudes, and search outcomes. The design was a post-test-only control group; recruitment by stratified randomization (by profession), blocked at 800. End-user training was more effective than no training in improving clinical question formulation, in raising awareness, knowledge, confidence and use of databases, but had made no impact on preference for secondary databases. It changed the attitude of clinicians to become more positive towards the use of electronic information services (EIS). Participants had higher search performance and outcomes (satisfaction with information obtained (NNT = 3), EIS satisfaction (NNT = 3) and success in problem solving (NNT = 4)). The workshop improved knowledge and skills in evidence-based searching, but this effect gradually eroded with time. Search logs confirmed that follow-up is required if effects are to be sustained. Longer effects on search behaviours appear to be positive. A randomised controlled trial is valuable in identifying cause-and-effect relations and to quantify the magnitude of the effects for management decision-making. To evaluate the effectiveness and efficiency of a search strategy to find evidence-based answers to questions related to the possible occupational etiology of diseases.
                A controlled trial of 70 occupational health physicians and 55 insurance physicians who were asked to answer one out of four 'occupational disease case-vignettes' following the steps of evidence-based medicine (EBM). The intervention group were given the search strategy as a tool.
                The intervention group scored significantly better than the control group in answering the main question of the case-vignette correctly (57% versus 37%) using more adequate search terms. The intervention group scored significantly better regarding satisfaction with the applied search strategy (28% very satisfied versus 8%). We found no differences in time spent in solving the case or in the intention of future practice of EBM.
                The introduction and application of specific search strategies can have a positive effect on the effectiveness of searching literature. Future initiatives for developing and testing specific search strategies in the field of occupational health should be encouraged.
Evidence from our review suggests that interventions to increase the quality of questions formulated in practice produce mixed results at both short- (immediately following intervention), and moderate-term follow up (up to nine months), comparatively. Although three studies reported effectiveness estimates of an educational intervention for increasing the quality of question formulation within the short term, only one study examined the effectiveness in the longer term (one year) and revealed that search skills had eroded over time. Data suggests that sustainability of effects from educational interventions for question formulation are unknown.
