Peri‐operative Mortality Following Cholecystectomy in Australia: Potential Preventability of Adverse Events

Abstract

Background Cholecystectomy is a commonly performed procedure; however, it is not without risks. It is crucial to constantly audit surgical outcomes in order to improve quality of care. The aim of this retrospective population-based cohort study is to identify preventable issues of clinical management associated with adverse occurrences in order to reduce mortality of cholecystectomy patients. Methods Data were obtained from the Australian and New Zealand Audit of Surgical Mortality (ANZASM). It encompasses peer-reviewed first and second line assessments of management of cholecystectomy patients who died from 2005 to 2015 in Australia. Clinical Management Issues (CMIs) were identified from text in assessments and grouped into communication failures, pre-operative, intra-operative and post-operative categories. These were further classified into subthemes using thematic analysis with a data-driven approach. Results There were 359 deaths in the study period. CMIs were present in 71 cases, with a reported total of 124 concerns or adverse events. Post-operative CMIs were the most prevalent issue [50% (62/124)], with the most common theme being delay to recognise complications (19/124). Pre-operative concerns were the second most common (n = 34). Decision to operate was questioned in 14 cases, and delay to surgery was reported in 12 cases. Conclusion ANZASM analysis has allowed us to identify modifiable adverse occurrences. This audit shows that delay to recognise complications is the most common assessment recorded. Preventive measures should be taken to improve outcomes and reduce peri-operative mortality, with an emphasis on post-operative management and enhancing communication between members of the multidisciplinary team.

Understanding Potentially Preventable Mortality Following Oesophago-Gastric Cancer Surgery: Analysis of a National Audit of Surgical Mortality

“…Overall, the findings from this study can inform surgical practice and training, and can be used as a basis for prioritizing quality improvement initiatives. Moreover, many of our findings can be applied to other surgical specialties, 18 – 22 and other disciplines may also benefit from a similar analysis of mortality data.…”

“…Broadly, the themes identified from our analysis of clinical management issues overlapped with other examinations of mortality following cholecystectomy, 18 neurosurgery, 19 cardiothoracic surgery, 20 pancreaticoduodenectomy 21 and hepatectomy. 22 …”

Increasing use of intraoperative cholangiogram in Australia: is it evidence‐based?

“…However, BDI in present day LC is extremely rare, with rates between 0.2% and 0.3%, and only 0.1% representing major injury or complication 4,7,10 . Of course, BDI can be a significant complication when it does occur; BDI‐associated mortality has been estimated to be approximately 3.5%, although historical reports were at 9.4% 1,3,11,12 …”
