Objectives To assess whether Portuguese family physicians perform preventive health services in accordance with scientific evidence, based on the recommendations of the United States Preventive Services Task Force (USPSTF).
Design Cross-sectional study.
Setting Primary healthcare, Portuguese National Health Service.
Participants 255 Portuguese family physicians selected by a stratified cluster sampling design were invited to participate in a computer-assisted telephone survey.
Outcomes Prevalence of compliance with USPSTF recommendations for screening, given a male and female clinical scenario and a set of proposed medical interventions, including frequency of the intervention and performance in their own daily practice.
Results A response rate of 95.7% was obtained (n=244). 98–100% of family physicians answered according to the USPSTF recommendations in most interventions. In the male scenario, the lowest concordance was observed in the evaluation of prostate-specific antigen with 37% of family physicians answering according to the USPSTF recommendations. In the female scenario, the lowest concordance was for cholesterol testing with 2% of family physicians complying. Family physicians younger than 50 years had significantly better compliance scores than older ones (mean 77% vs 72%; p<0.001).
Conclusions We found a high degree of agreement with USPSTF recommendations among Portuguese family physicians. However, we also found results suggesting excessive use of some medical interventions, raising concerns related to possible harm associated with overdiagnosis and overtreatment.
