RT Journal A1 Shanafelt T, Habermann T T1 MEdical residents' emotional well-being JF JAMA JO JAMA YR 2002 FD October 16 VO 288 IS 15 SP 1846 OP 1847 DO 10.1001/jama.288.15.1845 UL http://dx.doi.org/10.1001/jama.288.15.1845 AB While Bellini et al state they were unaware of previous longitudinal studies reporting on variations in mood during the course of the internship, we are aware of 2 studies that reported similar data.3- 4 Like the study by Bellini et al, one of these studies found that depression and fatigue in residents was greatest in February.3 Over the last 2 decades, the negative emotional consequences of residency training have been well documented. In an effort to improve the situation, the Accreditation Council for Graduate Medical Education (ACGME) recently published new guidelines that restrict resident work hours.5 While these regulations represent an effort toward meaningful progress, little evidence was available to guide these changes, and the extent to which they will improve emotional distress in residents remains unknown. Future studies of resident distress should focus on identifying causes and solutions for resident distress rather than just further describing the problem. More important, studies exploring how to promote residents' well-being are needed to understand not only how to eliminate the problem but also how to promote residents' emotional health.
