Immediate effects of urgent reorganisation of emergency department-based treatment pathway in nonperforated appendicitis: a retrospective study.

Background: Acute appendicitis is a global disease and a very common indication for emergency surgery worldwide. The need for hospital resources is therefore constantly high. The administration in Kanta-Häme Central Hospital, Southern Finland, called for an urgent reorganisation due to shortage of hospital beds at the department of general surgery. Postoperative treatment pathway of patients with nonperforated acute appendicitis was ordered to take place in the Emergency Department (ED). The aim of this study was to assess, whether this reorganisation was feasible and safe, i.e. did it affect the length of in-hospital stay (LOS) and the 30-day complication rate.
Methods: This is a retrospective pre- and post-intervention analysis. After the reorganisation, most patients with nonperforated appendicitis were followed postoperatively at the 24-h observation unit of the ED instead of surgical ward. Patients operated during the first 3 months after the reorganisation were compared to those operated during the 3 months before it. A case met inclusion criteria if there were no signs of appendiceal perforation during surgery. Exclusion criteria comprised age < 18 years and perforated disease.
Results: Appendicectomy was performed on 112 patients, of whom 62 were adults with nonperforated appendicitis. Twenty-seven of the included patients were treated before the reorganisation, and 35 after it. Twenty of the latter were followed only at the ED. Postoperative LOS decreased significantly after the reorganisation. Median postoperative time till discharge was 15.7 h for all patients after the reorganisation compared to 24.4 h before the reorganisation (standard error 6.2 h, 95% confidence interval 2.3-15.2 h, p < 0.01). There were no more complications in the group treated postoperatively in the ED.
Conclusions: Early discharge of patients with nonperforated appendicitis after enforced urgent reorganisation of the treatment pathway in the ED observation unit is safe and feasible. Shifting the postoperative monitoring and the discharge policy of such patients to the ED - instead of the surgical ward - occurred in the majority of the cases after the reorganisation. This change may spare resources as in our series it resulted in a significantly shorter LOS without any increase in the 30-day complication rate.
