title: Outcomes after thyroidectomy and parathyroidectomy.
abstract: BACKGROUND
  Previous reports on postoperative outcomes following thyroid and parathyroid surgery are limited by relatively small sample size. We report 30-day outcomes following thyroid and parathyroid surgery and analyze factors affecting length of stay (LOS) and postoperative adverse events (AEs).
  
  
  METHODS
  The multicenter, prospective, National Surgical Quality Improvement Program (NSQIP) datasets (2007/2008) were used. Multivariable logistic regression and analysis of covariance (ANCOVA) were performed.
  
  
  RESULTS
  Patients undergoing thyroidectomy, parathyroidectomy, or both were identified (n = 13,380, 6154, 1535, respectively). Thirty-day mortality was 0.08%, 0.16%, and 0.2%, respectively; 30-day morbidity was 3.50%, 3.02%, and 4.04%, respectively. Mean LOS values were 1.1 ± 1.4, 1.1 ± 2.1, and 1.4 ± 3.1 days, respectively. Congestive heart failure, dependent functional status, dialysis dependence, and chronic corticosteroid use were significantly associated with increased LOS and postoperative AE.
  
  
  CONCLUSIONS
  Morbidity and mortality rates following thyroid and parathyroid surgery are low. These data could be used by third-party interests, and surgeons should be aware of them to ensure their outcomes are in the national norm.
