Abstract

Background

Inappropriate admission and hospitalization are types of overuse that impose a financial burden on all health systems, especially in hospitals.

Objective

To analyze the evidence on the inappropriateness of admission and hospitalization in Iranian hospitals.

Methods

This study was conducted using PubMed, Embase, Scopus, and Web of Science, as well as Persian databases, including Magiran and Scientific Information Database up to May 2018. Two researchers extracted result of the included studies, independently. We used Cohen’s κ statistic for measuring inter-rater agreement. The meta-analyses were conducted based on pooled effect estimates for the rate of admission and hospitalization using the DerSimonian-Laird random-effects model with 95% confidence intervals (CI).

Results

Seventeen articles met the inclusion criteria. The inter-rater agreement was very good for abstracts and full-texts screening (κ 0.86 and 98, respectively). The overall inappropriate rate was 12.3% (95% CI, 8.4-17.5) and 11.9% (95% CI, 7.7-18.1) for admission and hospitalization, respectively. The inappropriate rate of admission was significantly higher before the Health Sector Evolution Plan (HSEP) than after HSEP (14.6%, 95% CI, 8.6-23.6 before HSEP and 10%, 95% CI, 5.5-17.3 after HSEP), and the inappropriate rate of hospitalization was significantly higher after HSEP than before HESP (9.5%, 95% CI, 5.2-16.7 before HSEP and 16.9%, 95% CI, 8.2-31.7 after HSEP).

Conclusions

Adoption standard measures of admission and hospitalization, treating patients in appropriate care centers, and establishing a referral system is essential to reduce the inappropriate admission and hospitalization in Iranian hospitals. Such interventions can lead to a reduction in personnel costs and workload and ultimately increase the productivity of the hospital.
