Economic evaluation of antibiotic therapy versus appendicectomy for the treatment of uncomplicated acute appendicitis from the APPAC randomized clinical trial
Abstract
BACKGROUND: An increasing amount of evidence supports antibiotic therapy for treating uncomplicated acute appendicitis. The objective of this study was to compare the costs of antibiotics alone versus appendicectomy in treating uncomplicated acute appendicitis within the randomized controlled APPAC (APPendicitis ACuta) trial.
METHODS: The APPAC multicentre, non-inferiority RCT was conducted on patients with CT-confirmed uncomplicated acute appendicitis. Patients were assigned randomly to appendicectomy or antibiotic treatment. All costs were recorded, whether generated by the initial visit and subsequent treatment or possible recurrent appendicitis during the 1-year follow-up. The cost estimates were based on cost levels for the year 2012.
RESULTS: Some 273 patients were assigned to the appendicectomy group and 257 to antibiotic treatment. Most patients randomized to antibiotic treatment did not require appendicectomy during the 1-year follow-up. In the operative group, overall societal costs (€5989·2, 95 per cent c.i. 5787·3 to 6191·1) were 1·6 times higher (€2244·8, 1940·5 to 2549·1) than those in the antibiotic group (€3744·4, 3514·6 to 3974·2). In both groups, productivity losses represented a slightly higher proportion of overall societal costs than all treatment costs together, with diagnostics and medicines having a minor role. Those in the operative group were prescribed significantly more sick leave than those in the antibiotic group (mean(s.d.) 17·0(8·3) (95 per…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 273 participants or records.
