Abstract

Our observational study1 of patients with lower respiratory tract infection (LRTI) presenting in the primary care setting showed a decrease in hospital admissions and mortality among patients who were prescribed an antibiotic on the day of consultation compared with those who did not receive such treatment. This association remained statistically significant after other potential factors influencing the outcomes of LRTI were taken into account in a multivariate model. These factors included comorbidity and its proxies, frequent health-care utilization and prior antibiotic use.
