Wayne Putnam, MD, CCFP, FCFP Karen Mann, PhD Elizabeth Lindsay, PhD David Davis, MD, CCFP, FCFP A b s t r a c t Guidelines for screening for elevated serum cholesterol have been published in both Canada and the United States. Preventive practices have been difficult to integrate into episodic care. This study was designed to test the impact of an educational intervention to increase physicians’ screening for elevated cholesterol in their practices. It was hypothesized that physicians who participated in the intervention would demonstrate higher rates of appropriate screening. A three-group randomized controlled trial of an educational intervention was conducted over 10 months in family physicians’ private offices throughout Nova Scotia. Invitation letters were mailed to full-time family physicians with 5 or more years in practice. Fifty-nine (27.2% of 217 eligible) physicians entered and 51 completed the study. The study group physicians attended a half-day workshop emphasizing information regarding, and approaches to, screening. The primary outcome measure was of physician screening in their practice. The baseline preworkshop screening rate averaged 51.7% for all groups. The groups were similar in this regard (p = .14). Physicians in the two study groups who attended the workshop had higher postworkshop screening rates than the control group (p = .08). The lack of strongly statistically significant effects of the intervention may be deceiving when the high base screening rate and the high physician within-group variability are considered. Attempts to evaluate the impact of interventions must take into account the very large amount of information directed at physicians and the public regarding elevated cholesterol.
