An anonymous reader quotes a report from Ars Technica: The age of your doctor may impact the quality of the care you receive -- and even cut your chances of survival -- researchers report in the British Medical Journal. Harvard researchers looked over data on more than 700,000 hospital admissions of elderly patients cared for by nearly 19,000 physicians between 2011 and 2014. They found that mortality rates crept up in step with physician age. Patients with doctors under the age of 40 had a 30-day mortality rate of 10.8 percent. With doctors aged 40 to 49, mortality rates inched up to 11.1 percent, then to 11.3 percent with doctors 50 to 59, and 12.1 percent with doctors aged 60 or above. The stats are adjusted for a variety of variables, such as hospital mortality rates and severity of patients' illnesses. All the patients were aged 65 or older and on Medicare. Though the age-related mortality trend was significant overall, it broke down when researchers sorted doctors by caseloads. Older doctors who saw high volumes of patients didn't see their patients' mortality rates increase.
