The cost and/or cost-effectiveness for inpatient management according to the gender of attending physicians remain to be elucidated.Hospitalization costs were extracted from the Diagnosis Procedure Combination (DPC) -based payment system. Using a dataset of 7,457 hospitalized patients with cardiovascular diseases in our hospital from 2012 to 2018, we compared the actual cost of inpatient management by female cardiologists with that by male cardiologists. Next, we estimated the cost-effectiveness of inpatient management according to the gender of the attending cardiologist. The cost of initial hospitalization per patient was similar between the patients treated by a female or male middle-grade cardiologist ($17,527 ± 14,158, versus $17,358 ± 15,183, P = 0.69). As an analysis on cost-effectiveness, the incremental cost of hospitalization managed by male middle-grade cardiologists was $67 per patient as compared with female middle-grade cardiologists. Concordantly, evaluation of the incremental cost-effectiveness ratio per quality-adjusted life year gained showed that the inpatient management by female cardiologists was dominant over that by male cardiologists.Inpatient management by female cardiologists was more cost-effective as compared with that by male cardiologists. Physician gender might have a considerable effect on medical economics.
