Factors predicting mortality in emergency abdominal surgery in the elderly

Area of Science:

• Geriatric Surgery
• Abdominal Emergency Medicine
• Surgical Outcomes Research

Background:

• Elderly patients (≥80 years) undergoing emergency abdominal surgery present unique clinical challenges.
• High morbidity and mortality rates are associated with acute abdominal conditions in this demographic.
• Identifying predictive factors for mortality is crucial for improving patient management and outcomes.

Purpose of the Study:

• To investigate the clinical features of emergency abdominal surgery in elderly patients.
• To determine factors that predict mortality in this patient population.

Main Methods:

• Retrospective analysis of 94 patients (≥80 years) undergoing emergency abdominal surgery (2000-2010).
• Evaluation of patient demographics, comorbidities, surgical indications, and performance status.
• Analysis of outcomes including morbidity, mortality, and use of scoring systems (APACHE II, POSSUM).
• Prognostic factors for mortality assessed using univariate and multivariate logistic regression analyses.

Main Results:

• 75.5% of patients had pre-existing medical conditions, most commonly hypertension.
• Acute cholecystitis (24.5%) and intestinal obstruction (19.1%) were the most frequent indications.
• Complications included surgical site infection (22.3%) and pneumonia (12.8%).
• Overall mortality was 16%, with sepsis and pneumonia being leading causes of death.
• Time to hospital admission and POSSUM scores were identified as significant prognostic factors for mortality.

Conclusions:

• Mortality in elderly patients undergoing emergency abdominal surgery is predictable.
• The POSSUM scoring system and delayed hospital admission are key prognostic indicators.
• These findings can inform clinical decision-making and resource allocation for high-risk elderly surgical patients.
