Optimal surgeon and hospital volume thresholds to reduce mortality and length of stay for CABG.

ABSTRACT:

Objective

We used nationwide population-based data to identify optimal hospital and surgeon volume thresholds and to discover the effects of these volume thresholds on operative mortality and length of stay (LOS) for coronary artery bypass surgery (CABG).

Design

Retrospective cohort study.

Setting

General acute care hospitals throughout Taiwan.

Participants

A total of 12,892 CABG patients admitted between 2011 and 2015 were extracted from Taiwan National Health Insurance claims data.

Main outcome measures

Operative mortality and LOS. Restricted cubic splines were applied to discover the optimal hospital and surgeon volume thresholds needed to reduce operative mortality. Generalized estimating equation regression modeling, Cox proportional-hazards modelin
