ABSTRACT OBJECTIVE To perform an economic cost analysis of the implementation of a short cervix screening program to reduce preterm birth in singleton pregnancies in a short-term time horizon. METHODS We performed a cost-benefit economic analysis using the P5 trial database, a randomized multicenter clinical trial for prevention of preterm birth. Data collection was conducted from July 2015 to March 2019 in 17 different Brazilian hospitals. We conducted a cost analysis for universal cervical screening in singleton pregnancies between 18 weeks and 22 weeks plus 6 days. In subjects with a cervical length ≤ 25 mm, the analysis incorporated the costs of administering 200 mg/day of vaginal progesterone prophylactically until 36 weeks gestation. These findings were subsequently compared with the economic implications of forgoing cervical screening. The time horizon comprised from birth to 10 weeks postpartum. The outcome was measured monetarily in Brazilian real (R$) from the perspective of the Unified Health System. RESULTS Among 7,844 women, 6.67% (523) had a cervix ≤ 25 mm. The cost of screening with transvaginal ultrasound and vaginal progesterone for prevention of births with < 34 weeks was estimated at R$ 383,711.36, while non-screening generated an estimated additional cost of R$ 446,501.69 (related to the 29 non-screened preterm deliveries). Thus, screening and prophylaxis would generate a final cost reduction of R$ 62,790.33, constituting a possible cost-benefit strategy. CONCLUSION Universal short cervix screening for preterm birth has lower costs compared to non-screening within a short-term time horizon, which suggests an interesting benefit-cost ratio. Future studies should consider the cost-effectiveness of prophylactic treatment using sensitivity analyses in different scenarios within the Brazilian health system, as well as analyses that consider the long-term costs associated with preterm births, to robustly justify the implementation of a short cervix screening program.

RESUMO OBJETIVO Realizar uma análise econômica de custo da implementação de um programa de rastreio de colo curto para redução da prematuridade em gestações únicas num horizonte temporal de curto prazo. MÉTODOS Realizamos uma análise econômica do tipo custo-benefício utilizando o banco de dados do P5 trial, um ensaio clínico multicêntrico randomizado para prevenção da prematuridade. A coleta de dados ocorreu de julho de 2015 a março de 2019 em 17 diferentes hospitais do Brasil. Comparamos os custos do rastreamento universal em mulheres com gestação única de 18 a 22 semanas e 6 dias associado à progesterona vaginal profilática 200 mg/dia até 36 semanas naquelas com colo ≤ 25 mm com os do não rastreamento. O horizonte temporal foi do nascimento até 10 semanas após o parto. O desfecho foi medido monetariamente em real brasileiro (R$) na perspectiva do Sistema Único de Saúde. RESULTADOS Entre 7.844 mulheres, 6,67% (523) apresentaram colo ≤ 25mm. O custo do rastreio com a ultrassonografia transvaginal mais a progesterona vaginal para prevenção de nascimentos < 34 semanas foi estimado em R$ 383.711,36, enquanto o não rastreamento gerou custo adicional estimado de R$ 446.501,69 (relacionado aos 29 partos prematuros não rastreados). Assim, o rastreamento mais a profilaxia geraria uma redução de custo final de R$ 62.790,33, apresentando-se como uma possível estratégia de custo-benefício. CONCLUSÃO O rastreamento universal de colo curto para prematuridade apresenta menores custos em relação ao não rastreamento dentro de um horizonte temporal de curto prazo, o que sugere uma interessante relação de custo versus benefício. Novos estudos que considerem a custo-efetividade do tratamento profilático utilizando-se de análises de sensibilidade em diferentes cenários dentro do sistema de saúde brasileiro, assim como análises que considerem os custos de longo prazo atrelados ao nascimento prematuro, são necessários para justificar com robustez a implementação de um programa de rastreamento.

OBJECTIVE: To evaluate the occurrence of Post-Traumatic Stress Disorder among women experiencing a severe maternal morbidity event and associated factors in comparison with those without maternal morbidity. METHODS: In a retrospective cohort study, 803 women with or without severe maternal morbidity were evaluated at 6 months to 5 years postpartum for the presence of Post-Traumatic Stress Disorder. Interviews were conducted by telephone and electronic data was stored. Data analysis was carried out by using χ2, Fisher’s Exact test, and logistic regression analysis. RESULTS: There was no significant change in the prevalence of Post-Traumatic Stress Disorder related to a previous severe maternal morbidity experience. There were also no differences in diagnostic criteria for severe maternal morbidity (hypertensive syndromes, hemorrhage, surgical intervention or intensive care unit admission required, among other management criteria). Low parity (2.5-fold risk) and increasing age were factors associated with Post-Traumatic Stress Disorder. CONCLUSIONS: A severe maternal morbidity episode is not associated with Post-Traumatic Stress Disorder symptoms within five years of the severe maternal morbidity event and birth. However, a more advanced maternal age and primiparity increased the risk of Post-Traumatic Stress Disorder. This does not imply that women who had experienced a severe maternal morbidity event did not suffer or need differentiated care.

OBJECTIVE: To assess the prevalence of pregnancy complications identified as maternal near miss (MNM) and associated factors among women using the public health care system in the Amazon and Northeast regions of Brazil. METHODS: A secondary analysis of a population-based survey conducted in 2010 was performed focusing on women self-reporting maternal complications. The main outcome was MNM, pragmatically defined as intensive care unit admission, eclampsia, hysterectomy, or blood transfusion. In addition, the risk of MNM was estimated for certain sociodemographics and characteristics of care received. Poisson regression was performed, generating adjusted prevalence ratios (PRadj) with 95% confidence intervals (95%CI). RESULTS: A total of 13 044 women (77%) who had given birth during the prior year using the public health system were interviewed. At least one complication was reported by 37.5%, with hemorrhage (28.4%) and infection (8.3%) being the most frequent. The overall MNM ratio was 31.5 per 1 000 live births, higher for the Amazon region than for the Northeast. Factors with a higher risk for developing MNM were: indigenous ethnicity (PRadj 2.77; 95% CI: 1.50-5.14), more than one hour to reach the hospital (PRadj 1.55; 95%CI: 1.06-2.25), being refused by a full hospital and having to find another one (PRadj 1.49; 95%CI: 1.03-2.16), cesarean section (PRadj 2.56; 95%CI: 1.90-3.44), and public prenatal care (PRadj 1.95; 95%CI: 1.06-3.61). CONCLUSIONS: Users of public health system in the Amazon and Northeast regions of Brazil have high MNM rates. Some characteristics of the women and of the care they received represent inequalities associated with higher risk for MNM. Specific actions are required to improve maternal health programs in these expansive areas of the country.

OBJETIVO: Evaluar la prevalencia de las complicaciones del embarazo establecidas como morbilidad materna extremadamente grave (MMEG), y los factores asociados, entre las usuarias del sistema de atención de salud pública en las zonas amazónica y noreste del Brasil. MÉTODOS:Se realizó un análisis secundario de una encuesta poblacional llevada a cabo en el 2010 y centrado en las mujeres que autonotificaban complicaciones obstétricas. El principal resultado fue la MMEG, definida a efectos prácticos como ingreso en una unidad de cuidados intensivos, eclampsia, histerectomía o transfusión de sangre. Se calculó además el riesgo de MMEG para determinadas características sociodemográficas y de la atención recibida. Se llevó a cabo una regresión de Poisson y se generaron las razones de prevalencia ajustadas (RPa) con intervalos de confianza de 95% (IC 95%). RESULTADOS:Se entrevistó a un total de 13 044 mujeres (77%) que habían dado a luz durante el año previo en el sistema de salud pública. Un 37,5% notificó como mínimo una complicación; la hemorragia (28,4%) y la infección (8,3%) fueron las más frecuentes. El índice general de MMEG fue de 31,5 por 1 000 nacidos vivos, más elevado en la región amazónica que en la noreste. Los factores que comportaron un riesgo mayor de MMEG fueron la etnicidad autóctona (RPa 2,77; IC 95% = 1,50-5,14), precisar más de una hora para llegar al hospital (RPa 1,55; IC 95% = 1,06-2,25), no ser admitida en un hospital por estar completo y tener que encontrar otro (RPa 1,49; IC 95% = 1,03-2,16), la cesárea (RPa 2,56; IC 95% = 1,90-3,44), y la asistencia prenatal pública (RPa 1,95; IC 95% = 1,06-3,61). CONCLUSIONES: Las usuarias del sistema de salud pública en las regiones amazónica y noreste del Brasil muestran tasas elevadas de morbilidad materna extremadamente grave. Algunas características de las mujeres y de la atención recibida comportan desigualdades asociadas con un riesgo mayor de morbilidad materna extremadamente grave. Se requieren acciones específicas que mejoren los programas de salud materna en estas amplias zonas del país.

OBJECTIVE: To evaluate the long-term reproductive consequences that affect women who have experienced potentially life-threatening or life-threatening (near-miss) maternal complications. INTRODUCTION: Although advances have been made in reducing maternal death, few studies have investigated the long-term repercussions of significant events such as severe maternal morbidity and maternal near-misses. These repercussions may be long-lasting and negatively affect quality of life. METHODS: A total of 382 women who had experienced a potentially life-threatening pregnancy-related condition within the last five years were analyzed in this retrospective cohort study. A control group of 188 women who gave birth without complications was also included. Trained interviewers contacted the subjects by telephone and completed a pre-coded, structured questionnaire on reproductive health. Data were analyzed using odds ratios adjusted for age. The main outcome measures were occurrence and outcome of subsequent pregnancies. RESULTS: The estimated risk of becoming infertile as a result of tubal ligation or hysterectomy was 3.5 times higher in women who experienced a maternal near-miss or severe maternal morbidity during the index pregnancy as compared to controls. Likewise, the risk of complications in subsequent pregnancies was five times greater in women who had experienced severe maternal morbidity. However, no differences were found in the occurrence or number of subsequent pregnancies or perinatal outcome. CONCLUSION: The occurrence of a life-threatening or potentially life-threatening maternal condition reduces future reproductive potential and increases the risk of complications in subsequent pregnancies.
