The aim of this study was to evaluate a possible age‐ and sex‐related effect of using structured data collection in the preoperative diagnosis of patients with suspected acute appendicitis.
Abstract
BACKGROUND: Structured preoperative data collection and computer-assisted methods are claimed to improve diagnostic accuracy in patients with acute abdominal pain. The aim of this study was to evaluate a possible age- and sex-related effect of using structured data collection in the preoperative diagnosis of patients with suspected acute appendicitis. METHODS: Between 1989 and 1994, clinical and demographic data from 1764 consecutive patients were recorded. In 1990 and 1992, various detailed symptom, clinical and laboratory data were collected prospectively on a structured registration form. Age- and sex-specific diagnostic accuracy as well as perforation rate were calculated for each year. RESULTS: Diagnostic accuracy increased significantly by 5 (95 per cent confidence interval (c.i.) 1-9) per cent when structured data registration was applied. In female patients aged between 13 and 40 years, diagnostic accuracy increased by 16 (95 per cent c.i. 8-24) per cent. Significant changes in diagnostic accuracy were not seen in other subgroups. Perforation rates remained unchanged during the entire study period. CONCLUSION: In this population-based study, diagnostic accuracy in patients operated on for suspected acute appendicitis increased for all patients when structured preoperative data collection was used. However, the only subgroup with a significant increase in diagnostic accuracy was female patients aged between 13 and 40 years. Perforation rate was unaffected by structured data collection.

It is suggested as a result of these studies that the provision of such a system to aid the clinician is both feasible in a real-time clinical setting, and likely to be of practical value, albeit in a small percentage of cases.

It is suggested that while computer-aided diagnosis is a valuable direct adjunct to the clinician dealing with the “acute abdomen,” he may also benefit in the short-term from the constant feedback he receives and from the disciplines and constraints involved in communicating with the computer.

A low diagnostic accuracy is a problem mainly at extremes of age and in females, while the perforation rate is unaffected and a conservative attitude to exploration seems justified.

Evaluation of the published data showed that the Alvarado score fulfilled all four criteria and the Lindberg, the Fenyö and the Christian scores fulfilled two criteria each, whereas the evaluation gives more realistic estimates of the routine performance in different clinical environments.

It is concluded that the early diagnosis and treatment of suspected appendicitis in girls and women of reproductive age may reduce the incidence of tubal infertility resulting from the sequelae of a ruptured appendix.

A retrospective review of 2,216 patients surgically treated for a clinical diagnosis of acute appendicitis was performed, and in 80% of cases, histologic acute appendectomy was found; 57% of these patients were male.

The long-term benefits of the system at Airedale reinforce the conclusions of the earlier short-term trials that a comparable system should probably be offered to all DGHs in the UK, not as an exercise in 'artificial intelligence' but as an effective continuing stimulus to good clinical practice.

46 Citations1992J M Wellwood, Svein I. Johannessen +1 more
Clinical data about patients with acute abdominal pain should be recorded on structured information sheets by junior doctors and early positive diagnosis should be encouraged before decisions affecting the patient's management are made, as well as improved computer support which may confer further benefits.

It is concluded that in the management of the acute abdomen a policy based on clinical decision combined with selective laparoscopy may be superior to one based on diagnostic probabilities alone.

Diagnostic laparoscopy is a useful diagnostic technique in women with suspected acute appendicitis, as it improves diagnostic accuracy, reduces the negative appendicectomy rate and avoids unnecessary laparotomy.

Substantial benefits followed the introduction of the computer-aided diagnostic support system; increased diagnostic accuracy of the whole surgical team, reduction in negative laparotomy rates, earlier surgical intervention for acute appendicitis, reduced in the number of cases of perforated appendix and more efficient use of resources.

The accuracy of diagnosis of the clinicians was superior to the accuracy of the computer diagnosis and there was no difference in diagnostic accuracy or frequency of operations or complications between patients managed by the two groups.

The difficulty in obtaining a correct pre-operative diagnosis in patients with suspected acute appendicitis is still a clinical problem of major concern and there was no correlation between time of admission and operation and accuracy of diagnosis, but a considerable variation in accuracy between different surgeons.

It can be concluded that the female sex hormones might play an important aetiological role in the development of acute appendicitis or influence the inflammatory process in the appendix.

In patients who underwent appendectomy or who were diagnosed as having periappendicular abscess during one year at a regional hospital in Denmark, the group of women in the fertile age (12-50 years) was prone to unnecessary surgery and in children, men and non-fertile women only a few patients had unnecessary surgery.
