Operative and Nonoperative Outcomes of Emergency General Surgery Conditions: An Observational Study Using a Novel Instrumental Variable.

ABSTRACT:

Objective

To determine the effect of operative versus nonoperative management of emergency general surgery conditions on short-term and long-term outcomes.

Background

Many emergency general surgery conditions can be managed either operatively or nonoperatively, but high-quality evidence to guide management decisions is scarce.

Methods

We included 507,677 Medicare patients treated for an emergency general surgery condition between July 1, 2015, and June 30, 2018.

Outcomes were mortality, complications, and readmissions.

Results
