Preoperative immobility significantly impacts the risk of postoperative complications in bariatric surgery patients

      Abstract

      Background

      Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes.

      Objectives

      The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes.

      Setting

      This study took place at a university hospital in the United States.

      Methods

      The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications.

      Results

      There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, P<.001) and greater operative times, length of stay, reoperation rates, and readmissions. Immobile patients had a greater risk of multiple complications, including acute renal failure (OR 6.42, P<.001), pulmonary embolism (OR 2.44, P = .01), cardiac arrest (OR 2.81, P = .05), and septic shock (OR 2.78, P = .02). Regardless of procedure type, immobile patients had a higher incidence of perioperative morbidity compared with ambulatory patients.

      Conclusions

      This study is the first to specifically assess the impact of immobility on 30-day bariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery.
