Access to neonatal healthcare services: analysis of displacement networks between municipalities in the State of Paraná, Brazil

Abstract:

This study aimed to characterize hospitalizations of residents in Paraná State, Brazil, that occurred during the neonatal period in a municipality different from their place of residence from 2008 to 2019, and to describe displacement networks for the first and last biennium of the series, corresponding to periods before and after initiatives to regionalize health services in the state. Admissions of children aged from 0 to 27 days were obtained from the Hospital Information System of the Brazilian National Unified Health System (SIH-SUS) database. For each biennium and health region, the proportion of admissions that occurred outside the municipality of residence, the weighted average distance traveled, and indicators of health and service provision were calculated. Mixed models were fitted to evaluate the biennial trend of the indicators and to investigate factors associated with the neonatal mortality rate (NMR). In total, 76,438 hospitalizations were selected, ranging from 9,030 in 2008-2009 to 17,076 in 2018-2019. The comparison of the networks obtained for 2008-2009 and 2018-2019 revealed an increase in the number of frequent destinations and in the proportion of displacements within the same health region. A decreasing trend was observed for distance, the proportion of live births with 5-minute Apgar ≤ 7, and for NMR. In the adjusted analysis for NMR, besides the biennial effect (-0.64; 95%CI: -0.95; -0.28), only the proportion of live birth with gestational age < 28 weeks showed statistical significance (4.26; 95%CI: 1.29; 7.06). The demand for neonatal hospital care increased over the study period. The displacement networks suggest a positive impact of regionalization, although investment in regions with the potential to become healthcare centers is necessary.
