Preoperative Internal Medicine Evaluation Reduces 30-Day Postoperative Mortality Risk in Patients with Cancer


 Background

The effect of preoperative internal medicine evaluations on cancer patients undergoing surgery is uncertain.
Methods

We conducted a retrospective cohort study of cancer patients who had been included in the National Surgery Quality Improvement Program from 2011–2014 to determine the effect of an Internal Medicine Perioperative Assessment Center (IMPAC) evaluation on the risk of 30-day mortality compared to that of patients who proceeded directly to surgery.
Results

Of the 11,577 participants, 3589 underwent an IMPAC evaluation. Among the propensity score-matched cohorts, the odds ratio (OR) of 30-day mortality was .39 (95% CI = .18-.84).
Conclusions

Our findings demonstrate that a preoperative internal medicine evaluation was associated with lower 30-day mortality.
