Clinical Summary

BMI, sleeve gastrectomy predict length of hospital stay in bariatric surgery

Takeaway

  • Factors associated with hospital stay longer than 1 day in patients undergoing bariatric surgery were sleeve gastrectomy (SG) and a BMI >50.
  • Early discharge on post-operative day 1 appeared to be safe and was not associated with higher readmission rates.

Why this matters

  • In current UK healthcare environment, there is an increasing pressure on hospitals to reduce treatment cost and early discharge from hospital could be one of the options.
  • Moreover, early discharge would encourage early mobilisation which could lead to reduced thromboembolic and chest-related complications.

Study design

  • This retrospective study evaluated 506 patients who underwent either laparoscopic Roux Y gastric bypass (RYGB; n=407) or SG (n=99) at a single institution.
  • Funding: None disclosed.

Key results

  • 58.5% and 30.3% patients who underwent RYGB and SG, respectively, were discharged on post-operative day 1.
  • Chances of hospital stay >1 day was 3.3-fold higher in patients undergoing SG (P<.001).
  • BMI <50 was associated with early discharge (P=.030).
  • Rate of readmission was similar between patients discharged on post-operative day 1 vs those discharged later (PFisher’s=.196) or those who underwent RYGB or SG (PFisher’s=.668).
  • Type 2 diabetes mellitus (P=.959), hypertension (P=.238), age >60 years (P=.144), female sex (P=.540), ischaemic heart disease (P=.573), dyslipidaemia (P=.412) and depression (P=.139) did not influence length of stay post-operatively.

Limitations

  • Retrospective design.
  • Single-centre study.
