Understanding unplanned return to theatre in rural South Australia general surgery: review of four major hospitals over a six-year period

BackgroundUnplanned return to theatre (URTT) is associated with longer hospital stay and higher mortality rates, placing extra burden on hospital resources. There is a lack of literature analysing causes of URTT in a rural general surgery department. This knowledge may be important to help identify patients at risk of URTT. This study aims to identify causes of URTT in rural general surgical patients. MethodsThis is a retrospective multicenter cohort involving four rural South Australian (SA) hospitals: Mount Gambier (MGH), Whyalla (WH), Port Augusta (PAH), and Port Lincoln (PLH). All general surgical inpatients admitted from February 2014 to March 2020 were analysed to identify all-cause of URTT. ResultsOf the 44 191 surgical procedures performed, there were 67 (0.15%) URTT. The most common surgical subspecialty cases that resulted in URTT were Colorectal (47.1%), General surgery (33.2%) Plastics (9.8%), and Hepatopancreatico-biliary (3.9%). The three commonest operations during URTT were washouts 22 (32.8%), interventions for haemostasis 11 (16.4%) and bowel resections 9 (13.4%). Sixteen (24%) of URTT followed emergency surgery. When comparing between elective and emergency admissions needing URTT, there were no statistical difference in age, gender, speciality type, types of surgery performed, and median number of days until URTT. ConclusionRates of URTT are low in South Australian rural hospitals when compared to our overseas counterpart. A wide range of surgery is being performed in rural centres, further supporting the need for rural surgical trainees to have a tailored curriculum encompassing subspecialities and being competent in managing any potential complications.

Automated summary

This study aims to identify the causes of unplanned return to theatre (URTT) in rural general surgical patients. The study found that the rates of URTT in South Australian rural hospitals are lower compared to overseas hospitals. The wide range of surgeries performed in rural centers highlights the need for tailored training programs for rural surgical trainees to manage potential complications.
