(ABC) — Does your doctor’s mental health and well-being affect the care you receive? A new study says yes — burnout, fatigue and depression may affect major medical errors.

Medical errors contribute to an estimated 100,000 to 200,000 deaths per year, according to the Institute of Medicine. Burnout — defined as emotional exhaustion or depersonalization — occurs in more than half of doctors, according to the study.

Researchers surveyed physicians across the country to understand the relationship between burnout and major medical errors in their careers.
