Résumé
Appendicitis is the most common cause of acute abdominal pain requiring surgical intervention. While many studies report readmission, a meta-analysis of readmission post-appendectomy has not been published. This meta-analysis was undertaken to determine rates and predictors of hospital readmission following appendectomy and to potentially provide a metric benchmark. An ethically approved PROSPERO-registered (ID CRD42017069040) meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using databases PubMed and Scopus, was undertaken for studies published between January 2012 and June 2017. Articles relating to outcomes and readmissions after appendectomy were identified. Those scoring >15 for comparative studies and >10 for non-comparative studies, using Methodological Index for Non-Randomized Studies criteria were included in the final analysis. The odds ratios (OR) using random-effects, Mantel-Haenszel method with 95% confidence intervals (CI), were computed for each risk factor with RevMan5. A total of 1757 articles reviewed were reduced to 45 qualifying studies for a final analysis of 836 921 appendectomies. 4.3% (range 0.0-14.4%) of patients were readmitted within 30 days. Significant preoperative patient factors for increased readmission were diabetes mellitus (OR 1.93, CI 1.63-2.28, P < 0.00001), complicated appendicitis (OR 3.6, CI 2.43-5.34, P < 0.00001) and open surgical technique (OR 1.39, CI 1.08-1.79, P < 0.00001). Increased readmission was not associated with gender, obesity or paediatric versus general surgeons or centres. This meta-analysis identified that readmission is not uncommon post-appendectomy, occurring in one in 25 cases. The mean readmission rate of 4.3% may act as a quality benchmark for improving emergency surgical care. Targeting high-risk groups with diabetes or complicated appendicitis and increasing use of laparoscopic technique may help reduce readmission rates.

BACKGROUND
Appendicitis is the most common cause of acute abdominal pain requiring surgical intervention. While many studies report readmission, a meta-analysis of readmission post-appendectomy has not been published. This meta-analysis was undertaken to determine rates and predictors of hospital readmission following appendectomy and to potentially provide a metric benchmark.
METHODS
An ethically approved PROSPERO-registered (ID CRD42017069040) meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using databases PubMed and Scopus, was undertaken for studies published between January 2012 and June 2017. Articles relating to outcomes and readmissions after appendectomy were identified. Those scoring >15 for comparative studies and >10 for non-comparative studies, using Methodological Index for Non-Randomized Studies criteria were included in the final analysis. The odds ratios (OR) using random-effects, Mantel-Haenszel method with 95% confidence intervals (CI), were computed for each risk factor with RevMan5.
RESULTS
A total of 1757 articles reviewed were reduced to 45 qualifying studies for a final analysis of 836 921 appendectomies. 4.3% (range 0.0-14.4%) of patients were readmitted within 30 days. Significant preoperative patient factors for increased readmission were diabetes mellitus (OR 1.93, CI 1.63-2.28, P < 0.00001), complicated appendicitis (OR 3.6, CI 2.43-5.34, P < 0.00001) and open surgical technique (OR 1.39, CI 1.08-1.79, P < 0.00001). Increased readmission was not associated with gender, obesity or paediatric versus general surgeons or centres.
CONCLUSION
This meta-analysis identified that readmission is not uncommon post-appendectomy, occurring in one in 25 cases. The mean readmission rate of 4.3% may act as a quality benchmark for improving emergency surgical care. Targeting high-risk groups with diabetes or complicated appendicitis and increasing use of laparoscopic technique may help reduce readmission rates.
