Transition to Ambulatory Bariatric Surgery (TABS) Trial

This study will compare same day discharge and at least one night stay in the hospital after bariatric surgery. Patients undergoing bariatric surgery will be randomized (i.e. have an equal chance of either plan) to either group. The study's primary outcome is the frequency patients in the study require a visit to the emergency room within 7 days of their surgery.

About this study

This pragmatic, parallel, randomized, open-label trial aims to determine the safety and feasibility of same day discharge (SDD) for bariatric surgery including sleeve gastrectomy and gastric bypass. Investigators will investigate the frequency of 7-day emergency department visits with SDD after bariatric surgery (Aim 1). In addition, the investigators will compare total 30-day charges between participants who undergo same day discharge versus those receive post-operative hospital admission (Aim 2).

Treatment and study plan

Same day discharge

Other

Patients in the same day discharge arm will be discharged from the hospital within 6 hours of arriving to the recovery unit and without an overnight stay in the hospital.

Primary outcomes

  1. Emergency Department Visits

    Time frame: baseline to seven days

    Number of emergency room visits after surgery

Secondary outcomes

  1. Readmissions to the hospital

    Time frame: baseline to 30 days

    Study personnel will investigate the incidence of readmissions to the hospital in the post-surgical period.

  2. The number of operations or procedures

    Time frame: baseline to 30 days

    Study personnel will compare the frequency of reoperations and procedural interventions after surgery
