Clinically Significant Infections in Surgical Mortality

Area of Science:

• Medical research
• Surgical outcomes
• Infection control

Background:

• Clinically significant infections (CSIs) are a major factor in surgical mortality, leading to extended hospital stays and increased death risk.
• Understanding the burden and contributing factors of CSIs in surgical deaths is crucial for improving patient outcomes.

Purpose of the Study:

• To examine the prevalence of CSIs in surgical deaths within the Australian Capital Territory.
• To identify factors associated with CSIs and explore opportunities for enhancing surgical care.

Main Methods:

• Utilized data from the Australian Capital Territory Audit of Surgical Mortality (ACTASM) from January 1, 2015, to December 31, 2024.
• Compared surgical mortality cases with and without CSIs to analyze differences in patient characteristics and outcomes.

Main Results:

• Out of 1089 cases, 363 involved CSIs. Patients with CSIs had more comorbidities, longer hospital stays, and fewer procedures.
• Infections acquired during admission (pneumonia) were more common than those acquired before admission (sepsis). General surgery had the most CSIs, while urology had the highest proportion.
• CSIs were associated with higher rates of unplanned readmissions, critical care admissions, returns to the operating theatre, and postoperative complications.

Conclusions:

• Surgical patients with CSIs who died presented with more comorbidities and longer hospitalizations, undergoing fewer operations compared to those without CSIs.
• Unplanned adverse events were significantly higher in patients with CSIs, highlighting their detrimental impact on surgical patient outcomes.
• Effective preventive strategies and prompt management of CSIs are essential for optimizing patient outcomes in surgical settings.
