BACKGROUND: One-third of Australia's population reside in rural and remote areas. This audit aims to describe all-causes of mortality in rural general surgical patients, and identify areas of improvement.
METHODS: This is a retrospective multi-centre study involving four South Australian hospitals (Mt Gambier, Whyalla, Port Augusta, and Port Lincoln). All general surgical inpatients admitted from June 2014 to September 2019 were analysed to identify all-cause of mortality.
RESULTS: A total of 80 mortalities were recorded out of 26 996 admissions. The overall mortality rate of 0.3% was the same as the 2020 Victorian state-wide Audit of Surgical Mortality. No mortality was secondary to trauma. Mean age was 79 ± 11 years and ASA was 3.9 ± 1. Malignancy was associated in over a third of cases (41.2%), mostly colorectal and pancreatic. Most cases were related to general surgical subspecialties: colorectal (51.3%), upper gastrointestinal (21.3%), hepatopancreaticobiliary (13.8%); however, there were also vascular (6.3%) and urology (3.8%) cases. The most common causes of mortality were large bowel obstruction (13.4%), ischemic bowel (10.4%), and small bowel obstruction (7.5%). Majority of mortality were beyond the surgeon's control (73.8%). Of the 21 potentially preventable mortalities, 42.9% were attributed to aspiration pneumonia and decompensated heart failure. Only one (1.3%) mortality case was due to pulmonary embolism.
CONCLUSION: Rural general surgical mortalities occur in older, comorbid patients. Rural surgeons should be equipped to manage basic subspeciality conditions. To further reduce mortalities, clear protocols to prevent aspiration pneumonia and resuscitation associated fluid overload are needed.
