Extended scope of practice needed for Australian rural general surgeons: a review of South Australia's rural general surgical caseload and case mix.

BACKGROUND: There is a shortage of surgeons caring for the 33% of Australians residing in rural and regional areas. In order to help appreciate what rural general surgery entails and optimize training for aspiring rural surgeons, the aim of this study was to analyse the general surgical departments' procedural caseload and casemix in four rural South Australian hospitals. METHODS: This is a retrospective multi-centre study involving four rural surgical centres in South Australia (Mt Gambier, Whyalla, Port Augusta, and Port Lincoln). Surgical procedures performed from 2014-2020 were extracted from departmental audits. To identify trends of surgical procedure over time, the data was divided into three time periods (Period 1: February 2014-December 2015, Period 2: January 2016-December 2017, Period 3: January 2018-March 2020). RESULTS: A total of 44 191 surgical procedures were performed, 70.2% being day procedures. 54% were endoscopic procedures, 46% were operative procedures. 60.6% of the operative procedures were general surgery procedures. 28.5% were general surgery-based subspecialty (colorectal, hepato-pancreato-biliary, upper gastrointestinal, and breast). 10.9% were non-general surgery-based subspecialty (urology, plastics, vascular, orthopaedics, head and neck, and obstetrics and gynaecology). There were no statistically significant fluctuations in procedure caseload in all aspects (endoscopic and operative procedures) over the three time periods. CONCLUSION: The majority of a rural Australian general surgeon's procedures are endoscopic. Operative procedures are mainly general surgery based. It may be beneficial to equip aspiring rural general surgeons to manage basic non-general surgery procedures (urological, vascular, and orthopaedic).
