A multidisciplinary perioperative medicine clinic to improve high-risk patient outcomes: A service evaluation audit

Various perioperative interventions have been demonstrated to improve outcomes for high-risk patients undergoing surgery. This audit assessed the impact of introducing a multidisciplinary perioperative medicine clinic on postoperative outcomes and resource usage amongst high-risk patients. Between January 2019 and March 2020, our institution piloted a Comprehensive High-Risk Surgical Patient Clinic. Surgical patients were eligible for referral when exhibiting criteria known to increase perioperative risk. The patient's decision whether to proceed with surgery was recorded; for those proceeding with surgery, perioperative outcomes and bed occupancy were recorded and compared against a similar surgical population identified as high-risk at our institution in 2017. Of 23 Comprehensive High-Risk Surgical Patient Clinic referrals, 11 did not proceed with the original planned surgery. Comprehensive High-Risk Surgical patients undergoing original planned surgery, as compared to high-risk patients from 2017, experienced reduced unplanned intensive care unit admission (8% versus 19%, respectively), 30-day mortality (0% versus 13%) and 30-day re-admission to hospital (0% versus 20%); had shorter postoperative lengths of stay (median (range) 8 (7-14) days versus 10.5 (5-28)) and spent more days alive outside of hospital at 30 days (median (range) 18 (0- 25) versus 21 (16-23)). Cumulatively, the Comprehensive High-Risk Surgical patient cohort compared to the 2017 cohort (both n1/423) occupied fewer postoperative intensive care (total 13 versus 24) and hospital bed-days (total 106 versus 212). The results of our Comprehensive High-Risk Surgical Patient pilot project audit suggest improved individual outcomes for high-risk patients proceeding with surgery. In addition, the results support potential resource savings through more appropriate patient selection.
