Introduction: The prevalence of substance abuse in bariatric patients has been well-documented in the literature. Several studies have alerted to the development of postoperative substance abuse in a small subset of bariatric patients. However, to what degree substance abuse affects patients’ postoperative outcomes and utilization of additional surgical procedures remains unclear.
Methods: We performed a retrospective review of a large-scale, state-based longitudinal hospital claims database (SPARCS) with mandatory reporting. All patients undergoing bariatric surgery between 2004 and 2010 were collected and outcomes were followed until 2014. Patients who had a diagnosis code for substance abuse within the previous 5 years before surgery were collected. Patients with revisional surgery, age less than 18, or lack of follow-up were excluded. Rates of subsequent surgery and postoperative outcomes were analyzed. Multivariate analysis was performed to control for procedural and patient variables.
Results: A total of 40,994 non-revisional bariatric patients were identified via inpatient and outpatient records. Patients with a previous diagnosis of substance abuse were shown to have longer lengths of stay following the index bariatric surgery (2.56 v. 1.96 days, p<0.0001) and higher overall complication rate (7.45% v. 5.28%, p<0.0001). Patients with substance abusewere more likely to undergo additional surgery after all types of bariatric procedures (p<0.0001). Among all bariatric patients who underwent subsequent surgery, substance abuse patients had a shorter time interval to additional surgery (337 v. 479 days, p<0.0001). Substance abuse patients had a higher rate of subsequent laparoscopic cholecystectomy and esophagogastroduodenoscopy (EGD), but no difference in rates of diagnostic laparoscopy or hernia repairs.
Conclusion: Bariatric surgery patients with a history of previous substance abuse experience a higher risk of postoperative complications and need for additional surgery, particularly laparoscopic cholecystectomy and EGD. These patients may require additional resources should they be deemed acceptable candidates for bariatric surgery.
