Abstract
BACKGROUND: Few studies have analyzed the relationship between surgical volume and outcomes after antireflux procedures. The aim of this study was to determine the effect of surgical volume on postoperative results and costs for patients undergoing surgery for gastroesophageal reflux disease.
METHODS: We analyzed the National Inpatient Sample (period 2000-2013). Adult patients (≥18 years old) with gastroesophageal reflux disease who underwent fundoplication were included. Hospital surgical volume was determined using the 30th and 60th percentile cut points using weighted discharges and categorized as low (<10 operations/year), intermediate (10-25 operations/year), or high (>25 operations/year). We performed multivariable logistic regression models to assess the effect of surgical volume on patient outcomes.
RESULTS: The studied cohort comprised 75,544 patients who had antireflux surgery. When operations performed at low-volume hospitals, postoperative bleeding, cardiac failure, renal failure, respiratory failure, and inpatient mortality were more common. In intermediate-volume hospitals, patients were more likely to have postoperative infection, esophageal perforation, bleeding, cardiac failure, renal failure, and respiratory failure. The length of hospital stay was longer at low- and intermediate-volume hospitals (1.08 and 0.55 days longer, respectively). There was an increase in charges of 5120 dollars per patient at low-volume centers, and 4010 dollars per patient at intermediate-volume centers.
CONCLUSIONS: When antireflux surgery is performed at high-volume hospitals, morbidity is lower, length of hospital stay is shorter, and costs for the healthcare system are decreased.
