Operative intervention rates for acute diverticulitis: a multicentre state-wide study

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Health Services Research

Background:

• Acute colonic diverticulitis presents a growing challenge to healthcare resources.
• Regional measurement of diverticulitis incidence and outcomes is crucial for treatment optimization.
• This study leverages Australian state-level administrative data to assess current practices.

Purpose of the Study:

• To determine current practices and outcomes for acute colonic diverticulitis in major metropolitan hospitals.
• To analyze emergency admissions and operative interventions using administrative data.
• To establish a baseline for improving diverticulitis treatment strategies.

Main Methods:

• Utilized coding algorithms to enhance yield and accuracy of Victorian Admitted Episodes Dataset.
• Analyzed emergency admissions for acute diverticulitis across eight tertiary referral centers (2009-2013).
• Measured key metrics including emergency operative intervention rates.

Main Results:

• 2829 emergency admissions for acute diverticulitis were recorded over 4 years.
• 724 admissions (25.6%) were complicated, with a 10.4% overall emergency operative intervention rate.
• Hartmann's procedure was the most frequent emergency resection (72%); median length of stay was 3 days (uncomplicated) and 6 days (complicated).

Conclusions:

• Hartmann's procedure is the predominant emergency surgical intervention for acute complicated diverticulitis in Victorian metropolitan hospitals.
• Administrative data provides a meaningful method for measuring practice patterns and outcomes in diverticulitis care.
• Findings highlight the importance of standardized data collection for quality improvement initiatives.
