Health Care Utilization Profiles in Young Ukrainian Refugee Children

Understanding how Ukrainian refugee children accessed the health care system after fleeing the war is essential to inform future preparedness and resource allocation in host countries.

To use latent class analysis of registry data to identify distinct health care utilization profiles among young Ukrainian refugee children who accessed the health care system in southern Poland in 2022.

This registry-based retrospective cohort study used electronic health record data from 2022 and included Ukrainian refugee children, aged 0 to 5 years, who received health care services in facilities in Małopolska Voivodeship, Poland. Participants were followed up from February 24 through December 31, 2022. The data were analyzed from April to October 2025.

Healthcare utilization indicators among postwar displaced Ukrainian refugee children used as inputs to the latent profile analysis.

Latent profile membership of health care utilization based on health care visit types, International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) coded diagnoses, and intensity of health care use, with temporal patterns of system entry and service trajectories examined after profile identification.

The analytic sample included 9845 Ukrainian refugee children aged 0 to 5 years (4849 [49.3%] female) who received 35 199 health care services in Małopolska Voivodeship in 2022. Age at first health care contact was evenly distributed across categories (mean [SD] of 2.7 [1.6] years), 3802 children (38.6%) had a single recorded service, 1845 (18.7%) had more than 5 services, and nearly half (4505 [45.8%]) received care in the regional capital (Krakow). Based on latent class analysis, 5 pediatric patient profiles were identified: mostly primary care (5216 [53.0%]), hospitalized with infectious diseases (1539 [15.6%]), highest health care use (1329 [13.5%]), emergency care for injuries (900 [9.1%]), and dental and preventive care (861 [8.7%]), differing in visit type, diagnostic patterns, and health care utilization intensity. Temporal patterns varied across profiles with earlier system entry among children requiring hospitalization for infectious diseases or emergency care for injuries, and later entry among those using primary care or dental and preventive care.

In this cohort study of pediatric Ukrainian refugees in southern Poland, distinct health care utilization patterns were observed with early reliance on hospital and emergency care followed by greater use of primary services. These findings underscore the need for refugee-hosting countries to rapidly adapt health care resources, prioritizing inpatient and emergency care in the initial months following a crisis.
