RESUMO
OBJECTIVE: This article aimed to report a temporal series of respiratory distress syndrome (RDS)-associated neonatal mortality rates in preterm live births in São Paulo state, Brazil, and to identify social, maternal, and neonatal characteristics associated with these deaths. STUDY DESIGN: This is a population-based study of all live births with gestational age (GA) between 22 and 36 weeks, birth weight ≥400 g, without congenital anomalies from mothers living in São Paulo state during 2004 to 2015. RDS-associated neonatal mortality was defined as death up to 27 days after birth with ICD-10 codes P22.0 or P28.0. RDS-associated neonatal mortality rate (annual percent change [APC] with 95% confidence intervals [95% CIs]) was analyzed by Prais-Winsten. Kaplan-Meier estimator identified the time after birth that the RDS-associated neonatal death occurred. Poisson's regression model compared social maternal and neonatal characteristics between preterm live births that survived the neonatal period and those with RDS-associated neonatal deaths, with results expressed in incidence rate ratio and 95% CI. RESULTS: A total of 645,276 preterm live births were included in the study, of which 612,110 survived and 11,078 had RDS-associated neonatal deaths. RDS-associated neonatal mortality rate was 17.17 per thousand preterm live births, with a decreasing annual trend (APC: -6.50%; 95% CI: -9.11 to -3.82%). The median time of these deaths was 48 hours after birth. The following risk factors for RDS-associated neonatal death were identified: maternal schooling ≤7 years (1.18; 1.09-1.29), zero to three prenatal care visits (1.25; 1.18-1.32), multiple pregnancy (1.24; 1.16-1.33), vaginal delivery (1.29; 1.22-1.36), GA 22 to 27 weeks (106.35; 98.36-114.98), GA 28 to 31 weeks (20.12; 18.62-21.73), male sex (1.16; 1.10-1.22), and 5-minute Apgar scores of 0 to 3 (6.74; 6.08-7.47) and 4 to 6 (3.97; 3.72-4.23). CONCLUSION: During the study period, RDS-associated neonatal mortality rates showed significant reduction. The relationship between RDS-associated neonatal deaths and social, maternal, and neonatal factors suggests the need for perinatal strategies to reduce prematurity and to improve the initial management of preterm infants. KEY POINTS: · RDS is associated with preterm live births.. · Impact of RDS-associated neonatal mortality in middle-income countries is scarce.. · Qualified perinatal care can reduce RDS-associated neonatal mortality..
RESUMO
OBJECTIVE: Many newborns are investigated and empirically treated for suspected early-onset sepsis (EOS). This study aimed to describe neonatologists' self-identified risk thresholds for investigating and treating EOS and assess the consistency of these thresholds with clinical decisions. STUDY DESIGN: Voluntary online survey, available in two randomized versions, sent to neonatologists from 20 centers of the Brazilian Network on Neonatal Research. The surveys included questions about thresholds for investigating and treating EOS and presented four clinical scenarios with varying calculated risks. In survey version A, only the scenarios were presented, and participants were asked if they would order a blood test or start antibiotics. Survey version B presented the same scenarios and the risk of sepsis. Clinical decisions were compared between survey versions using chi-square tests and agreement between thresholds and clinical decisions were investigated using Kappa coefficients. RESULTS: In total, 293 surveys were completed (145 survey version A and 148 survey version B). The median risk thresholds for blood test and antibiotic treatment were 1:100 and 1:25, respectively. In the high-risk scenario, there was no difference in the proportion choosing antibiotic therapy between the groups. In the moderate-risk scenarios, both tests and antibiotics were chosen more frequently when the calculated risks were included (survey version B). In the low-risk scenario, there was no difference between survey versions. There was poor agreement between the self-described thresholds and clinical decisions. CONCLUSION: Neonatologists overestimate the risk of EOS and underestimate their risk thresholds. Knowledge of calculated risk may increase laboratory investigation and antibiotic use in infants at moderate risk for EOS. KEY POINTS: · Neonatologists overestimate the risk of EOS.. · There is wide variation in diagnostic/treatment thresholds for EOS.. · Clinical decision on EOS is not consistent with risk thresholds.. · Knowledge of risk may increase investigation and treatment of EOS..

AIMS: To determine the infant mortality of newborns with 1- and 5-min Apgar scores of 0-3. RESULTS: Population cohort study with neonates with birth weight ≥400 g, gestational age ≥22 weeks and 1- and 5-min Apgar scores of 0-3, without malformations, born in São Paulo State (Brazil) from January 2006 to December 2007. Apgar scores were confirmed in the original certificates of live births and/or medical records. During this period, among 1,027,132 live births, 1640 met the study criteria, with an incidence of 1.6 per 1000 live births. When the 5-min Apgar score was 0, 1, 2 and 3, the infant mortality rate was 97%, 94%, 64% and 47%, respectively. Risk factors associated with infant deaths were 5-min Apgar score of 0 or 1 [odds ratio (OR) 16.6, 95% confidence interval (CI) 11.1-24.8], birth weight <2500 g (OR 7.5, 95% CI 5.7-9.8), birth at hospitals outside the state capital (OR 1.7, 95% CI 1.3-2.3), in private or charitable hospitals (OR 1.6, 95% CI 1.2-2.0), and during the night shift (OR 1.3, 95% CI 1.0-1.7). CONCLUSIONS: For infants with 1- and 5-min Apgar scores of 0-3, the infant mortality is high. Besides the biological variables associated with the chance of dying, the organization of the perinatal care influences the outcome.

BACKGROUND: In Brazil, the prevalence of prematurity has increased in recent years and it is a major cause of death in the neonatal period. Therefore, this study aims at assessing perinatal factors associated with early neonatal deaths in very low birth weight preterm infants born in a region of Brazil with low Human Development Index. METHODS: Prospective cohort study of inborns with gestational age 23(0/7)-31(6/7) weeks and birthweight 500-1499 g without malformations in 19 public reference hospitals of the state capitals of Brazil's Northeast Region. Perinatal variables associated with early neonatal death were determined by Cox regression analysis. RESULT: Among 627 neonates, 179 (29%) died with 0-6 days after birth. Early death was associated to: absence of antenatal steroids (HR 1.59; 95% CI 1.11-2.27), multiple gestation (1.95; 1.28-3.00), male sex (2.01; 1.40-2.86), 5th minute Apgar <7 (2.93; 2.03-4.21), birthweight <1000 g (2.58; 1.70-3.88), gestational age <28 weeks (2.07; 1.42-3.02), use of surfactant (1.65; 1.04-2.59), and non-use of a pain scale (1.89; 1.24-2.89). CONCLUSION: Biological variables and factors related to the quality of perinatal care were associated with the high chance of early death of preterm infants born in reference hospitals of Northeast Brazil.

OBJECTIVES: This pre/post-intervention study aimed to evaluate neonatal outcomes after the implementation of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics. METHOD: This interventional study was conducted across five secondary healthcare regions that supported 62 cities in the southwestern mesoregion of Piauí. It included 431 healthcare professionals responsible for neonatal care in the study region. The participants were trained in neonatal resuscitation through the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics. Delivery room structuring, healthcare professionals' knowledge, and neonatal care outcomes were analyzed immediately before and after intervention and after 12 months between February 2018 and March 2019, and healthcare professionals were evaluated. RESULTS: Training was conducted for over 106 courses. As a participant could take multiple courses, 700 training sessions were conducted. Regarding delivery room structuring, the acquisition of materials required for resuscitation increased from 28.4 to 80.6% immediately after the intervention and to 83.3% after 12 months. Knowledge retention was significant in the post-training period, with a 95.5% approval rate, and knowledge acquisition was satisfactory after 12 months. The number of newborns transferred during the study period increased significantly. A 72.6% reduction in mortality at birth was recorded, and 479 newborns were resuscitated. CONCLUSION: Following the implementation of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics, structural improvements in delivery rooms, adequate knowledge retention regarding neonatal resuscitation, and a consequent reduction in neonatal mortality were observed.

OBJECTIVE: This study was carried out to understand the disparities in mortality and survival without major morbidities among very premature and very low birth weight infants between participating Neonatal Intensive Care Units (NICUs) from the Brazilian Network on Neonatal Research (RBPN) and the Neonatal Research Network of Japan (NRNJ). METHODS: Secondary data analysis of surveys by the RBPN and NRNJ was performed. The surveys were conducted in 2014 and 2015 and included 187 NICUs. Primary outcome was mortality or survival without any major morbidity. Logistic regression analysis adjustment for confounding factors was used. RESULTS: The study population consisted of 6,406 infants from the NRNJ and 2,319 from the RBPN. Controlling for various confounders, infants from RBPN had 9.06 times higher adjusted odds of mortality (95%CI 7.30-11.29), and lower odds of survival without major morbidities (AOR 0.36; 95%CI 0.32-0.41) compared with those from the NRNJ. Factors associated with higher odds of mortality among Brazilian NICUs included: Air Leak Syndrome (AOR 4.73; 95%CI 1.26-15.27), Necrotizing Enterocolitis (AOR 3.25; 95%CI 1.38-7.26), and Late Onset Sepsis (LOS) (AOR 4.86; 95%CI 2.25-10.97). CONCLUSIONS: Very premature and very low birth weight infants from Brazil had significantly higher odds for mortality and lower odds for survival without major morbidities in comparison to those from Japan. Additionally, we identified the factors that increased the odds of in-hospital neonatal death in Brazil, most of which was related to LOS.

BACKGROUND: Infant mortality rate is a measure of population health and neonatal mortality account for great proportion of these deaths. Underdevelopment might be associated to higher neonatal mortality risk due to assistant related factors. Spatial and temporal distribution of mortality help identifying and developing strategies for interventions. OBJECTIVE: To investigate the cluster areas of asphyxia-associated neonatal mortality and to explore its association with per capita gross domestic product (GDP) in São Paulo State (SP), Brazil. METHODS: Ecological study including live births residents in SP from 2004-2013. Neonatal deaths (0-27 days) with perinatal asphyxia were defined as intrauterine hypoxia, birth asphyxia or meconium aspiration syndrome written in any line of the Death Certificate. Geoprocessing analytical approach included detection of first order effects through quintiles and spatial moving average maps, followed by second order effects by global and local spatial autocorrelation (Moran and LISA, respectively) before and after smoothing with local Bayesian estimates. Finally, Spearman correlation was applied between asphyxia-associated neonatal mortality and mean per capita GDP rates for the municipalities with significant LISA. RESULTS: There were 6,713 asphyxia-associated neonatal deaths among 5,949,267 live births (rate: 1.13/1000) in SP. Spatial moving average maps showed a non-random distribution among municipalities, with presence of clusters (I = 0.048; p = 0.023). LISA map identified clusters of asphyxia-associated neonatal mortality in the south, southeast and northwest. After applying local Bayes estimates, clusters were more pronounced (I = 0.589; p = 0.001). There was a partial overlap of the areas of higher asphyxia-associated neonatal mortality and lower mean per capita GDP. CONCLUSIONS: Spatial analysis identified cluster areas of high asphyxia-associated neonatal mortality and low per capita GDP rates, with a significant negative correlation. This optimized, structured, and hierarchical approach to identify high-risk areas of cause-specific neonatal mortality may be helpful for guiding public health efforts to decrease neonatal mortality.

OBJECTIVE: To evaluate perinatal factors associated with early neonatal death in preterm infants with birth weights (BW) of 400-1,500 g. METHODS: A multicenter prospective cohort study of all infants with BW of 400-1,500 g and 23-33 weeks of gestational age (GA), without malformations, who were born alive at eight public university tertiary hospitals in Brazil between June of 2004 and May of 2005. Infants who died within their first 6 days of life were compared with those who did not regarding maternal and neonatal characteristics and morbidity during the first 72 hours of life. Variables associated with the early deaths were identified by stepwise logistic regression. RESULTS: A total of 579 live births met the inclusion criteria. Early deaths occurred in 92 (16%) cases, varying between centers from 5 to 31%, and these differences persisted after controlling for newborn illness severity and mortality risk score (SNAPPE-II). According to the multivariate analysis, the following factors were associated with early intrahospital neonatal deaths: gestational age of 23-27 weeks (odds ratio - OR = 5.0; 95%CI 2.7-9.4), absence of maternal hypertension (OR = 1.9; 95%CI 1.0-3.7), 5th minute Apgar 0-6 (OR = 2.8; 95%CI 1.4-5.4), presence of respiratory distress syndrome (OR = 3.1; 95%CI 1.4-6.6), and network center of birth. CONCLUSION: Important perinatal factors that are associated with early neonatal deaths in very low birth weight preterm infants can be modified by interventions such as improving fetal vitality at birth and reducing the incidence and severity of respiratory distress syndrome. The heterogeneity of early neonatal rates across the different centers studied indicates that best clinical practices should be identified and disseminated throughout the country.

RESUMO Objetivo: Este estudo foi realizado para compreender as disparidades na mortalidade e sobrevivência sem as principais morbidades entre recém-nascidos muito prematuros e de muito baixo peso entre Unidades de Terapia Intensiva Neonatal (UTINs) participantes da Rede Brasileira de Pesquisas Neonatais (RBPN) e Rede de Pesquisa Neonatal do Japão (NRNJ). Métodos: Foi realizada uma análise dos dados secundários dos bancos de dados da RBPN e da NRNJ. As pesquisas foram realizadas em 2014 e 2015 e incluíram 187 UTINs. O desfecho primário foi mortalidade ou sobrevida sem qualquer morbidade importante. Utilizou-se a análise de regressão logística com ajuste para os fatores de confusão. Resultados: A população do estudo foi composta por 6.406 recém-nascidos do NRNJ e 2.319 do RBPN. Ajustando para diversos fatores de confusão, os prematuros da RBPN tiveram 9,06 vezes maiores chances de mortalidade (IC95% 7,30-11,29) e menores chances de sobrevivência sem morbidades importantes (AOR 0,36; IC95% 0,32-0,41) em comparação com os da NRNJ. Fatores associados a maiores chances de mortalidade entre as UTINs brasileiras incluíram: síndrome de escape de ar (AOR 4,73; IC95% 1,26-15,27), enterocolite necrosante (AOR 3,25; IC95% 1,38-7,26) e sepse de início tardio (AOR 4,86; IC95% 2,25-10,97). Conclusões: Os recém-nascidos muito prematuros e de muito baixo peso do Brasil apresentaram chances significativamente maiores de mortalidade e menores chances de sobrevivência sem as principais morbidades em comparação aos do Japão. Além disso, identificamos os fatores que aumentam as chances da morte neonatal no Brasil, sendo a maioria relacionada à sepse tardia.
RESUMO
OBJECTIVE: To assess the annual burden of early neonatal deaths associated with perinatal asphyxia in infants weighing ≥2500g in Brazil from 2005 to 2010. METHODS: The population study enrolled all live births of infants with birth weight ≥2500g and without malformations who died up to six days after birth with perinatal asphyxia, defined as intrauterine hypoxia, asphyxia at birth, or meconium aspiration syndrome. The cause of death was written in any field of the death certificate, according to International Classification of Diseases, 10th Revision (P20.0, P21.0, and P24.0). An active search was performed in 27 Brazilian federative units. The chi-squared test for trend was applied to analyze early neonatal mortality ratios associated with perinatal asphyxia by study year. RESULTS: A total of 10,675 infants weighing ≥2500g without malformations died within six days after birth with perinatal asphyxia. Deaths occurred in the first 24h after birth in 71% of the infants. Meconium aspiration syndrome was reported in 4076 (38%) of these deaths. The asphyxia-specific early neonatal mortality ratio decreased from 0.81 in 2005 to 0.65 per 1000 live births in 2010 in Brazil (p<0.001); the meconium aspiration syndrome-specific early neonatal mortality ratio remained between 0.20 and 0.29 per 1000 live births during the study period. CONCLUSIONS: Despite the decreasing rates in Brazil from 2005 to 2010, early neonatal mortality rates associated with perinatal asphyxia in infants in the better spectrum of birth weight and without congenital malformations are still high, and meconium aspiration syndrome plays a major role.

OBJECTIVE: The goal of the present study was to examine the decisions of pediatricians who teach neonatal resuscitation in Brazil, particularly those who start resuscitation in the delivery room for newborns born at 23-26 gestational weeks. METHODS: The present study was a cross-sectional study that used electronic questionnaires (Dec/11-Sep/13) sent to instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics. The primary outcome was the gestational age at which the respondent said that he/she would initiate positive pressure ventilation in the delivery room. Latent class analysis was used to identify the major profiles of these instructors, and logistic regression was used to identify variables associated with belonging to one of the derived classes. RESULTS: Of 685 instructors, 82% agreed to participate. Two latent classes were identified: 'pro-resuscitation' (instructors with a high probability of performing ventilation on infants born at 23-26 weeks) and 'pro-limitation' (instructors with a high probability of starting ventilation only for infants born at 25-26 weeks). In the multivariate model, compared with the 'pro-limitation' class, 'pro-resuscitation' pediatricians were more likely to be board-certified neonatologists and less likely to base their decision on the probability of the infant's death or on moral/religious considerations. CONCLUSION: The pediatricians in the most aggressive group were more likely to be specialists in neonatology and to use less subjective criteria to make delivery room decisions.

OBJECTIVE: To estimate the costs of hospitalization in premature infants exposed or not to antenatal corticosteroids (ACS). METHOD: Retrospective cohort analysis of premature infants with gestational age of 26-32 weeks without congenital malformations, born between January of 2006 and December of 2009 in a tertiary, public university hospital. Maternal and neonatal demographic data, neonatal morbidities, and hospital inpatient services during the hospitalization were collected. The costs were analyzed using the microcosting technique. RESULTS: Of 220 patients that met the inclusion criteria, 211 (96%) charts were reviewed: 170 newborns received at least one dose of antenatal corticosteroid and 41 did not receive the antenatal medication. There was a 14-37% reduction of the different cost components in infants exposed to ACS when the entire population was analyzed, without statistical significance. Regarding premature infants who were discharged alive, there was a 24-47% reduction of the components of the hospital services costs for the ACS group, with a significant decrease in the length of stay in the neonatal intensive care unit (NICU). In very-low birth weight infants, considering only the survivors, ACS promoted a 30-50% reduction of all elements of the costs, with a 36% decrease in the total cost (p=0.008). The survivors with gestational age <30 weeks showed a decrease in the total cost of 38% (p=0.008) and a 49% reduction of NICU length of stay (p=0.011). CONCLUSION: ACS reduces the costs of hospitalization of premature infants who are discharged alive, especially those with very low birth weight and <30 weeks of gestational age.

OBJECTIVE: To analyze the teaching of neonatal resuscitation offered by Brazilian public hospitals to undergraduate doctors and nurses, pediatric residents and neonatal fellows. METHODS: This cross-sectional multicenter study included 36 hospitals in 20 Brazilian State capitals during June/2003. Local coordinators collected data regarding what the institutions offer to undergraduate doctors and nurses, pediatric residents and neonatal fellows in terms of neonatal resuscitation training and practical activities in neonatal delivery room care. Descriptive analysis was performed. RESULTS: Twenty-three of the 36 institutions had undergraduate doctors: at 13 of them students had clinical activities in the delivery room, 12 offered neonatal resuscitation training, and at two of the 13 hospitals, interns cared for neonates in the delivery room without specific training. Twenty-three of the 36 hospitals had undergraduate nurses: at eight of them students had clinical activities in the delivery room and at seven of them nursing students cared for neonates in the delivery room without specific training. Twenty-seven of the 36 institutions had pediatric residence programs: at all of them, trained residents cared for neonates in the delivery room, but the training was heterogeneous: theoretical training (2-3 hours) at four institutions and theoretical and practical training (4-64 hours) at 23. Additionally, 15 had neonatal fellowship programs: at all of these, trained fellows cared for neonates in the delivery room, but the training was heterogeneous: theoretical training (2 hours) at one hospital and theoretical and practical training (3-68 hours) at 14. CONCLUSION: Formal neonatal resuscitation training is insufficient during medical and nursing graduation and heterogeneously offered to pediatric residents and neonatal fellows.

Resumo Objetivo: Avaliar a taxa anual de óbitos neonatais precoces associados à asfixia perinatal em neonatos de peso ≥ 2.500 g no Brasil de 2005 a 2010. Métodos: A população do estudo envolveu todos os nascidos vivos de neonatos com peso ao nascer ≥ 2.500 g e sem malformações que morreram até seis dias após o nascimento por asfixia perinatal, definida como hipóxia intrauterina, asfixia no nascimento ou síndrome de aspiração de mecônio. A causa do óbito foi escrita em qualquer linha do atestado de óbito, de acordo com a Classificação Internacional de Doenças, 10a Revisão (P20.0, P21.0 e P24.0). Foi feita uma pesquisa ativa em 27 unidades federativas brasileiras. O teste qui-quadrado de tendência foi aplicado para analisar os índices de mortalidade neonatal associados a asfixia perinatal até o ano do estudo. Resultados: Morreram 10.675 neonatos com peso ≥ 2.500 g sem malformações até 0-6 dias após o nascimento por asfixia perinatal. Os óbitos ocorreram nas primeiras 24 horas após o nascimento em 71% dos neonatos. A síndrome de aspiração de mecônio foi relatada em 4.076 (38%) dos óbitos. O índice de mortalidade neonatal precoce relacionada à asfixia caiu de 0,81 em 2005 para 0,65 por 1.000 nascidos vivos em 2010 no Brasil (p < 0,001); o índice de mortalidade neonatal precoce relacionada a síndrome de aspiração de mecônio permaneceu entre 0,20-0,29 por 1.000 nascidos vivos durante o período do estudo. Conclusões: Apesar da redução nas taxas no Brasil de 2005 a 2010, as taxas de mortalidade neonatal precoce associadas à asfixia perinatal em neonatos no melhor espectro de peso ao nascer e sem malformações congênitas ainda são altas e a síndrome de aspiração de mecônio desempenha um importante papel.

OBJECTIVE: The goal of the present study was to examine the decisions of pediatricians who teach neonatal resuscitation in Brazil, particularly those who start resuscitation in the delivery room for newborns born at 23-26 gestational weeks. METHODS: The present study was a cross-sectional study that used electronic questionnaires (Dec/11-Sep/13) sent to instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics. The primary outcome was the gestational age at which the respondent said that he/she would initiate positive pressure ventilation in the delivery room. Latent class analysis was used to identify the major profiles of these instructors, and logistic regression was used to identify variables associated with belonging to one of the derived classes. RESULTS: Of 685 instructors, 82% agreed to participate. Two latent classes were identified: ‘pro-resuscitation’ (instructors with a high probability of performing ventilation on infants born at 23-26 weeks) and ‘pro-limitation’ (instructors with a high probability of starting ventilation only for infants born at 25-26 weeks). In the multivariate model, compared with the ‘pro-limitation’ class, ‘pro-resuscitation’ pediatricians were more likely to be board-certified neonatologists and less likely to base their decision on the probability of the infant’s death or on moral/religious considerations. CONCLUSION: The pediatricians in the most aggressive group were more likely to be specialists in neonatology and to use less subjective criteria to make delivery room decisions.

Abstract Objective: To describe the opinions of pediatricians who teach resuscitation in Brazil on initiating and limiting the delivery room resuscitation of extremely preterm infants. Method: Cross-sectional study with electronic questionnaire (Dec/2011-Sep/2013) sent to pediatricians who are instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics, containing three hypothetical clinical cases: (1) decision to start the delivery room resuscitation; (2) limitation of neonatal intensive care after delivery room resuscitation; (3) limitation of advanced resuscitation in the delivery room. For each case, it was requested that the instructor indicate the best management for each gestational age between 23 and 26 weeks. A descriptive analysis was performed. Results: 560 (82%) instructors agreed to participate. Only 9% of the instructors reported the existence of written guidelines at their hospital regarding limitations of delivery room resuscitation. At 23 weeks, 50% of the instructors would initiate delivery room resuscitation procedures. At 26 weeks, 2% would decide based on birth weight and/or presence of fused eyelids. Among the participants, 38% would re-evaluate their delivery room decision and limit the care for 23-week neonates in the neonatal intensive care unit. As for advanced resuscitation, 45% and 4% of the respondents, at 23 and 26 weeks, respectively, would not apply chest compressions and/or medications. Conclusion: Difficulty can be observed regarding the decision to not resuscitate a preterm infant with 23 weeks of gestational age. At the same time, a small percentage of pediatricians would not resuscitate neonates of unquestionable viability at 26 weeks of gestational age in the delivery room.
Resumo Objetivo: Descrever opiniões dos pediatras que ensinam reanimação no Brasil a respeito de iniciar e limitar a reanimação em sala de parto de neonatos pré-termo extremos. Método: Estudo transversal com questionário eletrônico (dez/11-set/13) enviado aos instrutores do Programa de Reanimação Neonatal da Sociedade Brasileira de Pediatria com três casos clínicos hipotéticos: 1) decisão de iniciar ou não a reanimação; 2) limitação ou não dos cuidados intensivos após a reanimação em sala de parto; 3) limitação ou não da reanimação avançada em sala de parto. Para cada caso foi solicitada a indicação da conduta para cada idade gestacional entre 23-26 semanas. A análise foi descritiva por meio da frequência das respostas. Resultados: Consentiram em participar 560 (82%) instrutores. Apenas 9% afirmaram existir em seu hospital norma escrita sobre quando não iniciar a reanimação em sala de parto. Com 23 semanas, 50% dos instrutores fariam a reanimação em sala de parto e com 26 semanas 2% baseariam sua decisão no peso ao nascer e/ou na abertura da fenda palpebral. Dos entrevistados, 38% reavaliariam sua decisão e limitariam o cuidado na UTI a medidas de conforto para nascidos de 23 semanas reanimados na sala de parto. Quanto aos procedimentos de reanimação avançada, 45% e 4% com 23 e 26 semanas, respectivamente, não indicariam tais manobras. Conclusão: Observa-se dificuldade na opção de não reanimar neonatos com 23 semanas de gestação e, ao mesmo tempo, um pequeno percentual de pediatras não reanima, na sala de parto, neonatos cuja viabilidade não é questionada (26 semanas).

ABSTRACT OBJECTIVE: To estimate the costs of hospitalization in premature infants exposed or not to antenatal corticosteroids (ACS). METHOD: Retrospective cohort analysis of premature infants with gestational age of 26-32 weeks without congenital malformations, born between January of 2006 and December of 2009 in a tertiary, public university hospital. Maternal and neonatal demographic data, neonatal morbidities, and hospital inpatient services during the hospitalization were collected. The costs were analyzed using the microcosting technique. RESULTS: Of 220 patients that met the inclusion criteria, 211 (96%) charts were reviewed: 170 newborns received at least one dose of antenatal corticosteroid and 41 did not receive the antenatal medication. There was a 14-37% reduction of the different cost components in infants exposed to ACS when the entire population was analyzed, without statistical significance. Regarding premature infants who were discharged alive, there was a 24-47% reduction of the components of the hospital services costs for the ACS group, with a significant decrease in the length of stay in the neonatal intensive care unit (NICU). In very-low birth weight infants, considering only the survivors, ACS promoted a 30-50% reduction of all elements of the costs, with a 36% decrease in the total cost (p = 0.008). The survivors with gestational age <30 weeks showed a decrease in the total cost of 38% (p = 0.008) and a 49% reduction of NICU length of stay (p = 0.011). CONCLUSION: ACS reduces the costs of hospitalization of premature infants who are discharged alive, especially those with very low birth weight and <30 weeks of gestational age.
RESUMO OBJETIVO: Estimar os custos da internação hospitalar de prematuros cujas mães receberam ou não corticoide antenatal (CEA). MÉTODO: Coorte retrospectiva de prematuros sem malformações congênitas com idade gestacional de 26 a 32 semanas, nascidos entre janeiro/2006 e dezembro/2009, em hospital público, terciário e universitário brasileiro. Coletaram-se dados demográficos maternos e dos recém-nascidos (RN), a morbidade neonatal e o uso de recursos de saúde durante a internação hospitalar. Os custos foram analisados pela técnica de microcosting. RESULTADOS: Dos 220 nascidos que obedeciam a critérios de inclusão, 211 (96%) prontuários foram revisados: 170 receberam CEA e 41 não receberam a medicação. Analisando-se toda a população, houve redução de 14-37% entre os diferentes componentes do custo nos pacientes expostos ao CEA, sem significância estatística. Na análise de prematuros que receberam alta hospitalar vivos, o grupo com CEA teve redução de 24-47% nos vários componentes dos custos hospitalares, com diminuição significativa dos dias de internação em terapia intensiva. Os nascidos com peso < 1.500 g, considerando-se somente os sobreviventes, são aqueles que mais se beneficiaram da administração do CEA, com redução significativa de todos os componentes dos custos em 30-50%, diminuição de 36% no custo total (p = 0,008). Para o grupo com idade gestacional < 30 semanas, também sobreviventes, houve diminuição do custo total de 38% (p = 0,008) e redução de 49% dos dias de internação em UTI neonatal (p = 0,011). CONCLUSÕES: O CEA reduz o custo hospitalar de prematuros que sobrevivem à internação após o parto, principalmente naqueles abaixo de 1.500 g e 30 semanas de idade gestacional.

OBJECTIVE: To develop and validate a predictive score for clinical complications during intra-hospital transport of infants treated in neonatal units. METHODS: This was a cross-sectional study nested in a prospective cohort of infants transported within a public university hospital from January 2001 to December 2008. Transports during even (n=301) and odd (n = 394) years were compared to develop and validate a predictive score. The points attributed to each score variable were derived from multiple logistic regression analysis. The predictive performance and the score calibration were analyzed by a receiver operating characteristic (ROC) curve and Hosmer-Lemeshow test, respectively. RESULTS: Infants with a mean gestational age of 35 ± 4 weeks and a birth weight of 2457 ± 841 g were studied. In the derivation cohort, clinical complications occurred in 74 (24.6%) transports. Logistic regression analysis identified five variables associated with these complications and assigned corresponding point values: gestation at birth [<28 weeks (6 pts); 28-34 weeks (3 pts); >34 weeks (2 pts)]; pre-transport temperature [<36.3°Cor >37°C(3pts); 36.3-37.0°C (2 pts)]; underlying pathological condition [CNS malformation (4 pts); other (2 pts)]; transport destination [surgery (5 pts); magnetic resonance or computed tomography imaging (3 pts); other (2 pts)]; and pre-transport respiratory support [mechanical ventilation (8 pts); supplemental oxygen (7 pts); no oxygen (2 pts)]. For the derivation and validation cohorts, the areas under the ROC curve were 0.770 and 0.712, respectively. Expected and observed frequencies of complications were similar between the two cohorts. CONCLUSION: The predictive score developed and validated in this study presented adequate discriminative power and calibration. This score can help identify infants at risk of clinical complications during intra-hospital transports.

Objetivo: Analisar resultados desfavoráveis ââna alta hospitalar de prematuros nascidos em centros universitários públicos brasileiros. Métodos: Coorte prospectiva de 2646 recém-nascidos com idade gestacional de 23 a 33 semanas e peso ao nascer de 400 a 1499 g, sem malformações, nascidos em 20 centros no período de 2012 a 2013. O desfecho desfavorável foi definido como morte ou sobrevida hospitalar na alta hospitalar com ≥1 morbidades principais: displasia broncopulmonar (DBP) em 36 semanas corrigidas, hemorragia intraventricular (IVH) graus 3-4, leucomalácia periventricular (PVL) ou retinopatia tratada cirurgicamente prematuridade (ROP). Resultados: Entre 2646 crianças, 1390 (53%) morreram ou sobreviveram com as principais morbidades: 793 (30%) morreram; 497 (19%) tinham DBP; 358 (13%) tinham IVH 3-4 ou PVL; e 84 (3%) apresentaram ROP. A regressão logística ajustada pelo centro mostrou associação de desfecho desfavorável com: esteroides pré-natais (OR 0,70; IC 95% 0,55-0,88), cesariana (0,72; 0,58-0,90), idade gestacional <30 (4,00; 3,16-5,07), sendo masculino (1,44; 1,19-1,75), pequeno para a idade gestacional (2,19; 1,72-2,78), Apgar no quinto minuto <7 (3,89; 2,88-5,26), temperatura na admissão na UTIN <36,0 ° C (1,42; 1,15-1,76) , síndrome do desconforto respiratório (3,87; 2,995,01), sepse tardia comprovada (1,33; 1,051,69), enterocolite necrosante (3,10; 2,094,60) e persistência do canal arterial (1,69; 1,372,09). Conclusões: Mais da metade dos RNPT que nasceram em hospitais públicos estaduais de nível universitário 3 morrem ou sobrevivem com grandes morbidades.
