General description

Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) dataset is a national accreditation standard for bariatric surgery centers. It was obtained from the American College of Surgeons (ACS) and the American Society for Metabolic and Bariatric Surgery (ASMBS). All accredited centers report outcomes to the MBSAQIP database.

Variable categories

  • Preoperative risk factors;
  • Intraoperative variables;
  • 30-day postoperative;
  • Mortality and morbidity;
  • Some dates (hospital entry, dates of laboratory tests, and so on) have been recoded into durations (e.g., Date of Admission and Date of Discharge are recoded into Days to Discharge from Hospital Admit).

Limitations

  • Only patients over the age of 10 are available for assessment;
  • Patients over the age of 80 also have ages de-identified in the PUF (age is set to missing with an indicator variable included to identify patients over the age of 80);
  • All absolute dates have been removed, including the date of surgery;
  • Facility identifiers and geographic information regarding the origin hospital have been removed;
  • Preventive measures are not recorded, which can lead to an underestimation of the risk of certain conditions when such measures are routinely taken before surgery;
  • The data are submitted from centers participating in the MBSAQIP and do not represent a statistically representative sample for the nation;
  • Many patients do not undergo all possible preoperative laboratory tests, and therefore some of these variables have a high percentage of missing values (10% to 70%, depending on the tests).
