Abstract
Objective
To characterize patterns of secondary complications after inpatient head and neck surgery.
Study Design
Retrospective cohort study.
Setting
National Surgical Quality Improvement Program (2005-2015).
Subjects and Methods
We identified 18,584 patients who underwent inpatient otolaryngologic surgery. Four index complications were studied: pneumonia, bleeding or transfusion event (BTE), deep/organ space surgical site infection (SSI), and myocardial infarction (MI). Each patient with an index complication was matched to a control patient based on propensity for the index event and event-free days. Rates of 30-day secondary complications and mortality were compared.
Results
Index pneumonia (n = 254) was associated with several complications, including reintubation (odds ratio [OR], 11.7; 95% confidence interval [CI], 5.2-26.4), sepsis (OR, 8.8; 95% CI, 4.5-17.2), and death (OR, 5.3; 95% CI, 1.9-14.9). Index MI (n = 50) was associated with increased odds of reintubation (OR, 17.2; 95% CI, 3.5-84.1), ventilatory failure (OR, 5.8; 95% CI, 1.8-19.1), and death (OR, 24.8; 95% CI, 2.9-211.4). Index deep/organ space SSI (n = 271) was associated with dehiscence (OR, 7.2; 95% CI, 3.6-14.2) and sepsis (OR, 38.3; 95% CI, 11.6-126.4). Index BTE (n = 1009) increased the odds of cardiac arrest (OR, 3.9; 95% CI, 1.8-8.5) and death (OR, 2.9; 95% CI, 1.6-5.1).
Conclusions
Our study is the first to quantify the effect of index complications on the risk of specific secondary complications following inpatient head and neck surgery. These associations may be used to identify patients most at risk postoperatively and target specific interventions aimed to prevent or interrupt further complications.
