Abstract

Background: Health care systems are increasing efforts to minimize postoperative hospital stays to improve resource use. Common explanations for extended postoperative stay are baseline patient sickness, postoperative complications, or physician practice differences. However, the degree to which extended length of stay (LOS) represents patient illness or postoperative complications remains unknown. The aim is to investigate the influence of postoperative complications and elderly patient comorbidities on extended LOS after anterior cervical discectomy and fusion. Methods: This retrospective study was performed from January 1, 2008, to December 31, 2014, on data from the American College of Surgeons National Surgical Quality Improvement Program. Patient demographics, comorbidities, LOS, and inpatient complications were recorded. Multivariable logistic regression analysis was used to determine the odds ratio for risk-adjusted extended LOS. The primary outcome was the degree extended LOS represented patient illness or postoperative complications. Results: Of 4730 participants, 1351 (28.56%) had extended LOS. A minority of patients with extended LOS had a history of relevant comorbidities—diabetes (29.53%), chronic obstructive pulmonary disease (9.4%), congestive heart failure (1.04%), myocardial infarction (0.33%), acute renal failure (0.3%), and stroke (5.92%). Among patients with normal LOS, 96.8% had no complications, 2.7% had 1 complication, and 0.5% had greater than 1 complication. In patients with extended LOS, 79.4% had no complications, 14.5% had 1 complication, and 6.1% had greater than 1 complication (P < 0.0001). Conclusions: Our study suggests much of LOS variation after an anterior cervical discectomy and fusion is not attributable to baseline patient illness or complications and most likely represents differences in practice style or surgeon preference.
