To provide perspective on how the AAFP evaluates evidence regarding the net benefit of individual preventive services in children, I recently wrote an editorial in American Family Physician that reviewed the guideline process and discussed why there is insufficient evidence to recommend screening children for autism spectrum disorders, high blood pressure, and cholesterol levels. (Note to readers: although I am a member of the Commission on the Health of the Public and Science and verified that this editorial reflects current AAFP recommendations, it should not be considered an official statement of the AAFP.) Here is the bottom line:
Time is a precious clinical resource. Clinicians who spend time delivering unproven or ineffective interventions at health maintenance visits risk “crowding out” effective services. For example, a national survey of family and internal medicine physicians regarding adult well-male examination practices found that physicians spent an average of five minutes discussing prostate-specific antigen screening, but one minute or less each on nutrition and smoking cessation counseling. Similarly, family physicians have limited time at well-child visits and therefore should prioritize preventive services that have strong evidence of net benefit.
