Brief summary

The goal of this observational study is to assess the effect of functional status on bariatric surgical thirty-day outcomes. The main questions it aims to answer are: * Is functional status associated with higher incidence of 30-day unplanned resource utilization? * Is functional status associated with higher incidences of secondary adverse events? Participants will be sampled from the 2015-2019 American College of Surgeons National Surgical Quality Improvement Program

Interventions

PROCEDUREBariatric surgery

Current Procedural Terminology (CPT) codes: 43644, 43645, 43770, 43775, 43842, 43843, 43845, 43846, 43847.

DRUGGeneral anesthetic

Cases were required to have a documented general anesthesia anesthetic technique. Administered drugs were otherwise indeterminate under the current study design (observational study of a deidentified database).

DEVICEIndeterminate

Devices were indeterminate under the current study design (observational study of a deidentified database).

Design outcomes

Primary

Measure	Time frame	Description
Unplanned resource utilization (composite)	30 days	A composite binary outcome comprising unplanned readmission, return to the operating room, or prolonged (≥ 30 day) length of stay.

Secondary

Measure	Time frame	Description
Composite organ system complications	30 days	Cardiac complications included cardiac arrest and myocardial infarction. The only neurologic complication that was captured was stroke/cerebrovascular accident. Respiratory complications included reintubation, prolonged ventilatory wean, and pneumonia. Hematologic/infectious complications included superficial surgical site infection (SSI), deep incisional SSI, organ space SSI, wound dehiscence, bleeding, sepsis, septic shock, deep venous thrombosis, and pulmonary embolism. Renal complications included progressive renal insufficiency and acute kidney injury.
Mortality	30 days	Mortality
