RT Journal Article SR Electronic T1 Physician extenders on surgical services: the need for a systems perspective JF Canadian Journal of Surgery JO CAN J SURG FD Canadian Medical Association SP 80 OP 81 DO 10.1503/cjs.011117 VO 61 IS 2 A1 Smith, Heather A1 Kuziemsky, Craig A1 Champion, Caitlin YR 2018 UL http://canjsurg.ca/content/61/2/80.abstract AB Adding physician extenders (PEs) to surgical teams has the potential to affect care delivery in multiple ways. To develop evidence-based recommendations on integrating PEs into surgical teams, we must recognize that patient care is a complex, adaptive system and requires a health systems perspective to understand how changes will affect outcomes. It is the best method of assessing the system adaptations and trade-offs of adding PEs prior to implementation. Such work would help to optimize research and management of limited health care resources.
