Physicians' factors associated with quality and costs of care

Physician spending

This study investigates the variation in spending across physicians and its association with patient outcomes. (Tsugawa et al. JAMA Intern Med, 2017)

Access the study about physician spending

A graph shows "Adjusted Physician Spending Level" dollar amounts along the X axis and "Adjusted 30-Day Mortality Rate" percentages along the Y axis.

Physician age

This study investigates whether outcomes of patients who were admitted to hospital differ between those treated by younger and older physicians. (Tsugawa et al. JAMA Intern Med, 2017)

Access the study about physician age

A graphs shows "Physicians Age" in years along the X axis and "Adjusted 30-Day Mortality Rate" percentages along the Y axis.

Surgeons' factors associated with quality and costs of care and patient outcomes, and the utilization of care

Surgeons’ age and gender

This study investigates whether patients’ mortality differs according to the age and sex of surgeons. (Tsugawa et al. BMJ, 2018)

Access the surgeons' age and gender study

A graphs shows "Age of Surgeon" in years along the X axis and "Adjusted Operative Mortality Rate" percentages along the Y axis.

Surgeons' birthday

This study investigates whether patient mortality after surgery differs between surgeries performed on surgeons’ birthdays compared with other days of the year. (Kato, Jena, Tsugawa. BMJ, 2020)

Access the surgeons' birthday study
