Difference in access to health care for newly arrived refugees in Germany: a natural quasi-experiment
Abstract Background Providing quantitative evidence on structural access barriers to health care for newly arrived refugees constitutes a challenge due to a lack of suitable data. The coexistence of two different local access models in Germany allows for a comparative analysis of the association between access policies and realized access. Our study compares these two models to establish whether they lead to differences in access to care among refugees. Methods Municipalities in Germany’s largest federal state of North Rhine-Westphalia (NRW) have implemented different access models to which refugees are quasi-randomly assigned. We recruited 6 municipalities of which 3 decided to implement the health care voucher (HcV) model and 3 the electronic health card model (eHC) in a natural quasi-experimental study design. Analyses were based on claims data collected from the welfare offices or the statutory health insurance. We compared standardized incidence rates (SIR) based on 3 indicators: emergency service, ambulatory sensitive hospitalization and use of specialized care. Results We included data on health care use of all recently assigned refugees in the 6 municipalities over a period of 7 quarters (2016/17). The average quarterly sample size is n = 9,077 which corresponds to 6.5% of the population of recently assigned refugees in NRW at that time. We find differences in realized access between the models. For emergency care, the SIR differ significantly between municipalities using the HcV model (SIR:1.88; 95%-CI: 1.62-2.18) and eHC model (SIR:1.33; 95%-CI: 1.14-1.55). Conclusions Local decisions regarding the organization of access to health care are associated with differences in realized access to health care of refugees in NRW. The implementation of the eHC model may contribute to a decrease of emergency service. Further analyses should attempt to reduce a possible (self-)selection bias of municipalities which might have led to an underestimation of the difference between models. Key messages The organization of health care for newly arrived refugees on the local level is decisive for their access to care. Local policy makers may use their scope for action to remove access barriers for newly arrived refugees.
