Abstract
Frequent emergency department (ED) visits occur after esophagectomy. We aimed to identify the incidence of and risk factors for conversion from ED visit to inpatient admission.
A retrospective cohort study was performed of consecutive esophagectomies at a tertiary Canadian center (1999 to 2014). Multivariable regression analyses identified factors associated with conversion from ED visit to admission.
There were 520 esophagectomies with 6% inhospital mortality (n = 31). Of those discharged, 29.7% (n = 145) had one or more emergency visit and 43.4% (n = 63) of these patients were readmitted to the hospital. First-time ED visits resulted in inpatient conversion 23.4% of the time (n = 34); successive ED visits resulted in increasing conversion. On multivariable analysis, anastomotic leak (adjusted odds ratio 2.45; 95% confidence interval, 1 to 6.01; P = .05) was independently associated with higher odds of conversion to admission. Sensitivity analysis using Poisson regression to model conversion as a rate identified that living in regions further away was associated with lower conversion rate to admission (risk ratio 0.35; 95% confidence interval, 0.13 to 0.94; P = .04).
Although postesophagectomy ED utilization is high, the majority of visits do not convert to admission. With each increasing ED visit, likelihood of converting to admission increases. Anastomotic leakage was associated with higher odds of conversion to admission, possibly related to development of strictures. Access to urgent outpatient endoscopy may help reduce the incidence of ED visits and admission. Although living in regions further away is associated with lower conversion rates to admission at the index hospital, that may be due to patients utilizing closer local hospitals.
