Balancing the normal appendectomy rate with the perforated appendicitis rate: implications for quality assurance

Area of Science:

• Surgical outcomes research
• Appendicitis management

Background:

• The optimal "negative" appendectomy rate for suspected acute appendicitis remains debated.
• This controversy involves balancing risks of operating on a normal appendix versus complications of a perforated appendix.

Purpose of the Study:

• To determine an appropriate negative appendectomy rate using decision analysis.
• To evaluate the relationship between negative appendectomy and perforated appendicitis rates.

Main Methods:

• Decision analysis modeling probable outcomes.
• Review of over 10,000 appendectomy cases.
• Analysis of complication rates related to normal, acute, and perforated appendicitis.

Main Results:

• An inverse relationship exists between normal appendectomy and perforated appendicitis rates.
• Reducing perforated appendicitis rates improved overall complication rates, even with higher negative appendectomy rates.
• The perforation rate stabilized around 10%.

Conclusions:

• Surgical quality assessment should consider both normal appendectomy and perforated appendicitis rates.
• Focusing on reducing perforated appendicitis is key for improving patient outcomes in appendicitis care.
• Quality assurance should prioritize perforated appendicitis rates before evaluating normal appendectomy rates.
