Temporal changes in survival after cardiac surgery are associated with the thirty-day mortality benchmark.

ABSTRACT:

Objective

To assess the hypothesis that postoperative survival exhibits heterogeneity associated with the timing of quality metrics.

Data sources

Retrospective observational study using the Nationwide Inpatient Sample from 2005 through 2009.

Study design

Survival analysis was performed on all admission records with a procedure code for major cardiac surgery (n = 595,089). The day-by-day hazard function for all-cause in-hospital mortality at 1-day intervals was analyzed using joinpoint regression (a data-driven method of testing for changes in hazard).

Data extraction methods

A comprehensive analysis of a publicly available national administrative database was performed.

Principal findings

Statistically significant shifts in the pattern of postoperative m
