Top 20 Research Studies of 2019 for Primary Care Physicians.

This article summarizes the clinical questions and bottom-line answers from the top 20 POEMs of 2019. Taking blood pressure medications at night results in a large mortality reduction over six years compared with morning dosing. Automated devices are the best way to measure blood pressure. Nonfasting lipid profiles are preferred over fasting lipid profiles, and nonfasting and fasting lipid profiles are equally effective at predicting risk. The benefit of statins for primary prevention in people 75 years and older is uncertain at best. Aspirin has no net benefit for primary prevention of cardiovascular disease and has no effect on cancer outcomes. An Italian study found fecal immunochemical testing over five biennial screening cycles has a similar colorectal cancer yield as screening colonoscopy, whereas a meta-analysis found that taking aspirin, an anticoagulant, or a nonsteroidal anti-inflammatory drug has no impact on the positive predictive value of fecal immunochemical testing. Regarding infections, a meta-analysis showed that patients presenting with symptoms of acute respiratory tract infection are unlikely to have pneumonia if vital signs and the lung examination findings are normal. For streptococcal pharyngitis (strep throat), penicillin V at a dosage of 800 mg four times a day for five days is at least as effective as a dosage of 1,000 mg three times a day for 10 days. A primary care study in the United Kingdom reinforced that clinicians should counsel parents of ch...
