Perfil das internações por infecções do trato geniturinário na gravidez no SUS, de 2013 a 2022

Introduction: Genitourinary tract infections in pregnancy include urinary and genital conditions and may require hospital admission. Objective: To describe admissions for genitourinary tract infections in pregnancy within the Brazilian Unified Health System and contextualize regional differences in quantitative prenatal care adequacy. Methods: This descriptive ecological study examined hospital records classified under ICD-10 category O23 from 2013 to 2022. The hospitalization proportion used all Chapter XV admissions as its denominator. Records were described by race/skin color, age and administrative fields. Prenatal care data were obtained from the Live Birth Information System for 2014–2022, when classification was available, without individual linkage to hospital records. Results: There were 318,085 O23 admissions among 23,469,487 Chapter XV admissions (1.36%). Records classified as parda accounted for 42.48%, and those aged 20–29 years accounted for 52.30%. Unspecified urinary tract infection in pregnancy accounted for 150,785 records (47.40%). In the hospital tabulation, the North had the highest regional proportion (2.11%). In the live birth data, 17,579,978 of 25,541,508 births in 2014–2022 had adequate or more than adequate prenatal care (68.83%); the North had the lowest regional percentage (50.71%). Conclusion: These findings describe the composition of hospital admissions and regional differences between indicators covering distinct populations and periods. They do not estimate individual risk or the effect of prenatal care on hospitalization.
