title: Predicting potentially preventable hospital readmissions following bariatric surgery.
abstract: BACKGROUND
  Using hospital readmissions as a quality of care measure predicates that some readmissions were preventable.
  
  
  OBJECTIVE
  This study identifies predictors of potentially preventable readmissions (PPR) within 30 days of bariatric surgery discharge.
  
  
  METHODS
  New York State acute care hospitals.
  
  
  METHODS
  Adult inpatient surgical discharges, during 2012, with a principal diagnosis of overweight or obesity and a principal procedure for bariatric surgery were identified. Logistic regression was used to evaluate surgical approach, sex, age, race/ethnicity, payor, body mass index, complications and co-morbidities recorded during the surgical admission.
  
  
  RESULTS
  There were 10,448 surgeries studied for readmission of which 552 were followed by a PPR, for a statewide rate of 5.3 per 100 surgeries. Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) was the most common surgical approach (46.0%), then Sleeve Gastrectomy (SG) (41.3%), Laparoscopic Adjustable Gastric Band (LAGB) (8.1%), and Open Roux-en-Y Gastric Bypass (RYGB) (4.6%). RYGB had the highest PPR rate (8.8), followed by LRYGB (6.1), SG (4.3) and LAGB (3.3). Compared to LAGB, the odds of a PPR in patients with RYGB, LRYGB, and SG increased by 2.4 fold, 1.8 fold and 1.2 fold respectively. Black, non-Hispanic patients were at a greater risk of PPR (odds-ratio 2.0, P<.0001) compared to White, non-Hispanic patients while the risk of a PPR increased by 2-fold in patients with a surgical complication.
  
  
  CONCLUSIONS
  Taking all patient risk factors into account, the most significant predictors of a PPR were surgical approach, race and the presence of a surgical complication.
