RESUMEN
INTRODUCTION: A decline in surgical deaths has been observed in Australia since the introduction of the Australian and New Zealand Audit of Surgical Mortality (ANZASM). The current study was conducted to determine whether the perioperative mortality rate (POMR) has also declined. METHODS: This study is a retrospective review of the POMR for surgical procedures in Australian public hospitals between July 2009 and June 2013, using data obtained from the Australian Institute of Health and Welfare. Operative procedures contained in the Australian Refined Diagnosis Related Groups were selected and the POMR was modelled using urgency of admission, age and gender as explanatory covariates. RESULTS: The POMR in Australian public hospitals reduced by 15.4 % over the 4-year period. The emergency admissions POMR dropped from 1.40 to 1.12 %, and the elective admissions POMR from 0.09 to 0.08 %. The binary logistic regression model used to predict patient mortality showed emergency admissions to have a higher POMR than elective, being more evident at older ages. For emergency admissions, the difference in POMR between females and males increased with age, from about 55 years onwards, with females being lower. For elective surgeries, the difference between males and females was of little practical importance across ages. CONCLUSIONS: The reduction in the POMR in Australia confirms the reduction in surgical deaths reported to ANZASM. Continuing to monitor POMR will be important to ensure the safest surgery in Australia. Further investigations into case-mix will allow better risk adjustment and comparison between regions and time-periods, to facilitate continuous quality improvement.

BACKGROUND: Necrotising fasciitis (NF) is a life-threatening bacterial infection with high mortality. This retrospective study aimed to investigate patient characteristics and potential areas for improvement in clinical management in NF cases in Australia. METHODS: Retrospective analysis of surgical death data from all public and private Australian hospitals in every state and territory, excluding New South Wales, collected through the Australian and New Zealand Audit of Surgical Mortality for the 9-year period, January 2009 to February 2018. RESULTS: A total of 290 NF cases were identified. Among these NF cases, obesity and diabetes mellitus were two of the most common comorbidities, with a prevalence of 26% and 41%, respectively. A total of 41 clinical management issues (CMIs) were identified among 36 NF cases. A larger proportion of NF cases had CMIs compared with non-NF surgical mortality cases. Delay in diagnosis was the leading CMI (n = 28, 68.3%), followed by delay to surgery (n = 7, 17.1%). The majority of delayed diagnoses were attributed to non-surgical clinicians in the hospital. CONCLUSION: CMIs were identified in a larger proportion of NF cases than in other non-NF surgical mortality cases, suggesting that there are areas for improvement in NF diagnosis and management in Australia. The leading potentially avoidable issue identified in NF deaths was delay in diagnosis. This highlights the importance of awareness among non-surgical clinicians that NF is a surgical emergency requiring urgent debridement.

BACKGROUND: This study aimed to identify the most common potentially avoidable factors in urology deaths, focusing on the lessons that can be learnt. METHODS: This study analysed data from a well-established and comprehensive peer review audit of surgical deaths in Australian hospitals (excluding New South Wales) from 2009 to 2015, focusing on urology cases with identified areas for improvement in patient management. Of all audited deaths, 11% (79/719) had serious clinical management issues with a total of 109 individual clinical management issues identified. These were categorized based on perioperative stage (preoperative, intraoperative or post-operative), followed by thematic analysis within each stage. RESULTS: The study found preoperative issues to be the most common (n = 48), followed by post-operative issues (n = 32) with intraoperative issues less common (n = 13). Communication issues were seen at all three stages (n = 16). Overall, the most common theme was at the preoperative stage; inadequate preoperative assessment (n = 27). More specifically, the most common preoperative assessment issues involved a failure to order necessary preoperative investigations, or to administer necessary preoperative treatment (e.g. prophylactic antibiotics). The most common communication issue was between teams and at handover, often involving failure by junior medical staff to communicate issues to the responsible surgical consultant. CONCLUSION: Urological surgical cases with potentially avoidable mortality constitute a small, but important subset of deaths. The analysis of these cases can inform various stakeholders to improve the quality and safety of urological surgical care.

BACKGROUND: Independent peer review of mortality cases has potential to identify issues in cardiothoracic surgical patients. The Australian and New Zealand Audit of Surgical Mortality aims to improve surgical care through peer-reviewed assessment of all surgical mortality. The aim of this study was to describe common clinical management issues that contribute to patient mortality in a cohort of Australian cardiothoracic surgical patients. This approach may subsequently provide a basis for quality improvement. METHODS: Cardiothoracic mortality reports to the Australian and New Zealand Audit of Surgical Mortality from February 2009 through December 2015 were reviewed. The surgeon report and assessor comments were coded to identify clinical management issues. These were divided into perioperative stages (preoperative, intraoperative, and postoperative), and at each stage a thematic analysis was performed. RESULTS: Of the 908 cases analyzed, 1371 clinical management issues were identified. Postoperative issues were the most common (n = 552), followed by preoperative (n = 378) and intraoperative issues (n = 370). Communication issues were present at all 3 stages (n = 71). Overall the most common theme was intraoperative technical issues (n = 287). Many of these issues revolved around unintentional injury to anatomic structures during surgery and inadequate myocardial protection. Communication issues commonly related to surgical handover to the intensive care unit and lack of shared decision-making. Also common were consultant surgeons being unaware of patient deterioration or significant changes in management. CONCLUSIONS: The Australian and New Zealand Audit of Surgical Mortality provides valuable insights into issues affecting mortality in cardiothoracic patients. Potentially avoidable management issues play a large role in determining the outcome of these patients. Quality improvement initiatives targeting these areas may be valuable.

BACKGROUND: Clinical decision making is a core competency of surgical practice, involving a continuous and evolving process of data interpretation and evaluation. The aim of this article is twofold. First, to recognize patient deaths where a clinical incident arose following unsatisfactory clinical decision making, determining where in the clinical decision-making process each failure occurred. Second, to discuss and explore individual incidents to provide lessons from which the surgical community can learn. METHODS: Using the Australian and New Zealand Audit of Surgical Mortality database, all deaths from 1 January 2015 to 31 December 2015 were analysed. All deaths in which the surgeon or assessor identified an aspect of patient management that was inadequate were recognized. Clinical incidents deemed by the assessor to be an area of concern or an adverse event were individually reviewed to determine if a clinical decision-making incident (CDMI) occurred. CDMIs were categorized into various themes depending on the nature of the incident. RESULTS: A total of 3422 fully audited deaths occurred throughout the study period; from these cases, 226 individual CDMIs were identified. Decision to operate was the most commonly identified CDMI (n = 99, 43.8%), followed by diagnostic error (n = 49, 21.7%). The least common CDMI identified was inadequate post-operative assessment (n = 14, 6.2%). CONCLUSION: This paper demonstrates thought-provoking examples of clinical decision-making failure implicated in patient death. Clinical decision-making failures most commonly occur around the decision to operate with increased discussion of complex cases possibly required. Further CDMI evaluation should be considered to complement more traditional methods of surgical mortality evaluation.

BACKGROUND: Appendicectomy is a safe surgical procedure with minimal risks. Low mortality rates (0.04-0.24%) have been reported from a number of countries. Appendicectomy mortality rates have not been reported in Australia in recent years. The aim of the study was to conduct an appendicectomy mortality audit, to identify clinical management issues and to calculate the mortality rate of appendicectomy in Australia. METHODS: This study analysed data from a peer review of appendicectomy deaths in Australian hospitals of all states and territories, from 2006 to 2017. Additional procedural data were obtained from the Australian Institute of Health and Welfare for the calculation of mortality rates. RESULTS: The final analysis included 82 patients of whom 62 were elderly (age >65 years) with 47 males and 35 females. Two or more comorbidities were present in 68 patients. Open operation was performed in 62 patients, with complicated appendicitis found in 50 cases. The majority of management issues were non-surgical. Of the 16 surgical management issues identified, 11 issues occurred post-operatively in the elderly, which were potentially preventable. The overall mortality was 0.02% with 0.01% in the young (age <65 years) and 0.20% in the elderly. CONCLUSION: Australia's appendicectomy mortality rate was very low and comparable to international figures. Surgical management of appendicectomy was satisfactory in general. However, post-operative care in the elderly was found to be poor at times, with room for improvement. Further research is needed whether improvements in post-operative care could alter the clinical course to death in the elderly.

BACKGROUND: Mortality rates are commonly used to evaluate the quality of surgical care; however, a large proportion of surgical deaths are unavoidable. Examination of the potentially avoidable issues in surgical deaths can provide a strong basis for quality improvement. Using data from a well-established and comprehensive national surgical mortality audit, we sought to identify the most common avoidable factors in neurosurgical deaths, focusing on the lessons that can be learnt. METHODS: This study analysed data from a peer review audit of surgical deaths in Australian hospitals (excluding New South Wales) from 2009 to 2014, focusing on neurosurgery cases with identified areas for improvement in patient management. In the 6% of neurosurgical cases that had clinical incidents, there were 193 clinical events identified. These were first categorized based on the perioperative stage (pre-, intra- or postoperative) followed by thematic analysis within each stage. RESULTS: The study found preoperative issues to be the most common (n = 107) followed by postoperative issues (n = 31) and intraoperative issues (n = 29). The most common theme was inadequate assessment (n = 65) followed by poor communication (at any stage of treatment) (n = 26). CONCLUSION: Neurosurgical cases with potentially avoidable mortality constitute a small but important subset. Avoidable contributors to mortality occurred most frequently at the preoperative stage, most commonly relating to inadequate assessment and delays. These findings can inform various stakeholders to improve the quality and safety of surgical care.

BACKGROUND: The Western Australian Audit of Surgical Mortality was established in 2002. A 10-year analysis suggested it was the primary driver in the subsequent fall in surgeon-related mortality. Between 2004 and 2010 the Royal Australasian College of Surgeons established mortality audits in other states. The aim of this study was to examine national data from the Australian Institute of Health and Welfare (AIHW) to determine if a similar fall in mortality was observed across Australia. METHOD: The AIHW collects procedure and outcome data for all surgical admissions. AIHW data from 2005/2006 to 2012/2013 was used to assess changes in surgical mortality. RESULTS: Over the 8 years surgical admissions increased by 23%, while mortality fell by 18% and the mortality per admission fell by 33% (P < 0.0001). A similar decrease was seen in all regions. The mortality reduction was overwhelmingly observed in elderly patients admitted as an emergency. CONCLUSION: The commencement of this nation-wide mortality audit was associated with a sharp decline in perioperative mortality. In the absence of any influences from other changes in clinical governance or new quality programmes it is probable it had a causal effect. The reduced mortality was most evident in high-risk patients. This study adds to the evidence that national audits are associated with improved outcomes.
