[BDSP. Notice produite par INIST-CNRS 7T2w5R0x. Diffusion soumise à autorisation]. in icentifying appropriate strategies for effective use of preventive services for particular settings or popurations, public health practitioners employ a systematic approach to evaluating the literature. Behavioral intervention studies that focusion prevention, however, pose special challenges for these traditional methods. Tools for synthesizing evidence on preventive interventions can improve public nealth practice The authors developed a literature abstraction tool and a classification for preventive interventions. They incorporated the tool into a PC-basec relational database and user-friendly evidence reporting system, then tested the system by reviewing pehavioral interventions for hypertension management They performed a structured literature search and reviewed 100 studies on behavioral interventions for hypertension management. They abstracted information using the abstraction tool and classified important elements of interventions for comparison across studies The authors found that many studies in their pilot project did not report sufficient information to allow for complete evaluation, comparison across studies, orreplication of the intervention. They propose that studies report ing on oreventive interventions should (a) categorize interventions into cistrete components ; (b) report sufficient participant information : and (c) report characteristics such as intervention leaders, timing, and setting so that public health professionals can compare and select the most appropriate interventions.
