About this study
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.
Read the detailed description
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).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Same Day DischargeOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Same Day Discharge | Active comparator | Patients in the same day discharge will be discharged from the hospital following surgery without an overnight stay in the hospital. Receives: Other: Same Day Discharge |
| Standard of care - Hospital Admission | No intervention | Patients in the standard of care arm will be admitted to the hospital for at least one overnight stay in the hospital. |
