Socioeconomic disadvantage drives avoidable hospital admissions. This review identifies effective interventions to reduce health inequalities and inform policymakers on successful strategies for reducing hospital admissions among disadvantaged populations.
Area of Science:
- Public Health
- Health Services Research
- Health Equity
Background:
- Rising hospital admissions present a global challenge, increasing healthcare costs.
- Socioeconomic disadvantage is a primary risk factor for avoidable hospital admissions, exacerbating health inequalities.
- There is a need to identify effective interventions to mitigate these disparities.
Purpose of the Study:
- To systematically review interventions aimed at reducing socioeconomic inequalities in avoidable hospital admissions.
- To identify what strategies are effective, ineffective, and where evidence gaps exist for policymakers.
- To understand the nuances of intervention implementation in diverse socioeconomic contexts.
Main Methods:
- Systematic review of studies published from 2000-2020 in OECD countries.
- Inclusion of interventions targeting socioeconomically disadvantaged populations or reporting differential effects by socioeconomic status.
- Comprehensive electronic searches (MEDLINE, Embase, CINAHL, Cochrane CENTRAL, Web of Knowledge) supplemented by citation and grey literature searches.
- Narrative synthesis and meta-analysis where feasible, examining intervention effectiveness and characteristics.
Main Results:
- The review will analyze the effectiveness of various interventions in reducing socioeconomic disparities in hospital admissions.
- Interventions will be categorized by their domain of action and approach to addressing inequalities.
- Contextual factors influencing intervention organization, implementation, and delivery will be examined.
Conclusions:
- Findings will guide policymakers in developing targeted strategies to reduce avoidable hospital admissions among disadvantaged groups.
- The review aims to inform evidence-based policymaking for improved health equity.
- Identifying successful interventions can lead to more cost-effective healthcare systems by reducing unnecessary admissions.
