Objective To determine the prevalence of depression and burnoutamong residents in paediatrics and to establish if a relationexists between these disorders and medication errors.

Design Prospective cohort study.

Setting Three urban freestanding children’s hospitalsin the United States.

Participants 123 residents in three paediatric residency programmes.

Main outcome measures Prevalence of depression using the Harvardnational depression screening day scale, burnout using the Maslachburnout inventory, and rate of medication errors per residentmonth.

Results 24 (20%) of the participating residents met the criteriafor depression and 92 (74%) met the criteria for burnout. Activesurveillance yielded 45 errors made by participants. Depressedresidents made 6.2 times as many medication errors per residentmonth as residents who were not depressed: 1.55 (95% confidenceinterval 0.57 to 4.22) compared with 0.25 (0.14 to 0.46, P<0.001).Burnt out residents and non-burnt out residents made similarrates of errors per resident month: 0.45 (0.20 to 0.98) comparedwith 0.53 (0.21 to 1.33, P=0.2).

Conclusions Depression and burnout are major problems amongresidents in paediatrics. Depressed residents made significantlymore medical errors than their non-depressed peers; however,burnout did not seem to correlate with an increased rate ofmedical errors.
