In their article "Early Discharge of Infected Patients Through Appropriate Antibiotic Use," Eron and Passos1 compared the mean length of stay of 2 groups of patients with mild to moderate community-acquired infections. One group was treated by one of the authors who is an infectious disease (ID) hospitalist and the other group was treated by several internal medicine (IM) hospitalists. There are many flaws in the design of this study. In addition to a lack of randomization, the fact that one of the authors is the only ID physician compounds the potential bias in the study. A comparison of one ID specialist's practice habits with that of several IM hospitalists' is questionable as well.
