Summary

Structured data collection improved diagnostic accuracy for suspected appendicitis. The most significant gains were observed in female patients aged 13-40, while perforation rates remained unchanged.

Area of Science:

  • Medical Informatics
  • Surgical Diagnostics
  • Clinical Data Management

Background:

  • Structured preoperative data collection and computer-assisted methods are proposed to enhance diagnostic accuracy in acute abdominal pain.
  • Evaluating the impact of structured data collection on age- and sex-specific diagnostic accuracy for suspected acute appendicitis is crucial.

Purpose of the Study:

  • To assess the age- and sex-related effects of structured preoperative data collection on the diagnosis of suspected acute appendicitis.
  • To determine if structured data collection influences diagnostic accuracy and perforation rates in specific patient subgroups.

Main Methods:

  • A retrospective analysis of 1764 patients undergoing surgery for suspected appendicitis between 1989 and 1994.
  • Prospective collection of detailed symptom, clinical, and laboratory data using a structured registration form in 1990 and 1992.

  • Calculation of age- and sex-specific diagnostic accuracy and perforation rates for each study year.

    • Main Results:

    • Overall diagnostic accuracy increased by 5% with structured data collection (95% CI 1-9%).
    • A significant diagnostic accuracy increase of 16% (95% CI 8-24%) was observed in female patients aged 13-40 years.
    • No significant changes in diagnostic accuracy were noted in other patient subgroups; perforation rates remained stable.

    Conclusions:

    • Structured preoperative data collection enhances overall diagnostic accuracy for suspected acute appendicitis.
    • The most substantial improvement in diagnostic accuracy was identified in females aged 13-40 years.
    • Structured data collection did not impact the perforation rate in patients with suspected acute appendicitis.
