Background
Diabetes mellitus (DM) is a known risk factor for worse outcomes after emergency abdominal surgery (EAS). However, it is unclear if the type of diabetes treatment (insulin or oral agents) has any effect on outcomes after EAS.
Methods
Matched cohort study utilizing the ACS NSQIP database. Patients with DM undergoing EAS were divided into insulin and oral agent treatment groups. A 1:1 cohort matching of insulin-treated and oral agent-treated patients was performed (matched for sex, age, ASA score, BMI category, operative procedure, and preoperative acute renal failure, pneumonia, SIRS, sepsis, septic shock, and corticosteroid use). Outcomes of matched insulin- and oral agent-treated patients were compared with univariable and multivariable regression analysis.
Results
A total of 7401 patients with DM underwent EAS, 3182 (43 %) of which were insulin treated and 4219 (57 %) were treated with oral agents. Matching resulted in 2280 matched cases, which formed the basis of this analysis. Insulin-treated patients were more likely to have postoperative complications (OR 1.279, CI 1.119–1.462), had a higher 30-day mortality rate in patients with sepsis at hospital admission (OR 3.421, CI 1.959–5.974), and a longer total hospital length of stay (RC 1.115, CI 1.065–1.168) and postoperative LOS (RC 1.082, CI 1.031–1.135).
Conclusions
In patients with DM undergoing emergency abdominal surgery, insulin-treated patients have worse outcomes than oral agent-treated patients. Insulin-treated patients with DM therefore should be monitored and treated more intensively in anticipation of potential complications after emergency abdominal surgery.
