The Health Roundtable KEY PROBLEM  Bariatric Surgery  Treat severe obesity  Cure obesity related comorbidity  Laparoscopic Sleeve Gastrectomy offered at CMDHB  Associated with significant perioperative morbidity  Prolong convalescence  Impair surgical recovery  Enhanced Recovery After Surgery (ERAS) protocols  Multiple evidence-based perioperative care interventions to optimise and standardise perioperative care  Reduce morbidity and length of stay (LOS) in other types of surgery  Comparably less evidence in bariatric surgery 2

The Health Roundtable AIM OF THIS INNOVATION  Aim:  To investigate whether a bariatric specific ERAS protocol was effective at improving recovery after LSG  A randomised controlled trial was conducted to investigate the efficacy and safety of an ERAS protocol  Exposure arm (EG): Perioperative care according to ERAS  Control arm (CG): Standard perioperative care  Matched propensity scores used to generate an historical control group (HCG) to account for potential cross over as a result of inadequate blinding  Primary outcome: Reduction in LOS from 3 days to 1 day requiring 38 patients in each arm  Other outcomes: Postoperative complications, readmission rates, postoperative fatigue, protocol compliance, perioperative costs 3

The Health Roundtable BASELINE DATA  All procedures performed at the Manukau Surgery Centre, Auckland, New Zealand  400 patients had LSG between 2006 and 2010  Primary outcome: Reduction in LOS from 3 days to 1 day  Other outcomes: Postoperative complications, readmission rates, perioperative costs ($NZ) 4

The Health Roundtable KEY CHANGES IMPLEMENTED Exposure GroupControl Group Preoperative Standardised education Routine advice Formal goal setting Tour of the ward Intraoperative Clear oral fluids up to 2 hours pre surgery Care as per individual anaesthetist and surgeon CHO loading 8mg IV dexamethasone Standardised anaesthesia Intraperitoneal local anaesthetic Avoidance of prophylactic drains and NGTs 5

The Health Roundtable OUTCOMES SO FAR Exposure (n=40) Control (n=38) Historic (n=38) p LOS Index Admission (IQR) 1 day (1-2) a 2 days (0) b 3 days (2-4) <0.001 Readmission LOS Total (IQR) 1 day (1-3) a 2 days (1-2) b 3 days (2-4) <0.001 a Signficantly reduced in ERAS group compared to both non-ERAS and historical group b Signifcantly reduced in non-ERAS group compared to historical group 7

The Health Roundtable OUTCOMES SO FAR Exposure (n=40) Control (n=38) Historic (n=38) p Total Complications Major Complications Cost per patient (SD) $14, (13,092) a $15, (14,920) b $27, (26,976) a Significant reduction in the Exposure Group when compared to the Historical Group b Significant reduction in the Control Group when compared to the Historical Group 8

The Health Roundtable LESSONS LEARNT  A bariatric specific ERAS protocol reduced LOS after surgery and was cost effective without increasing perioperative morbidity 9
