Family Integrated Care for Preterm Infants in China: A Cluster Randomized Controlled Trial.

OBJECTIVE: To explore whether family integrated care (FICare) is feasible and improves the outcomes of preterm infants in China. STUDY DESIGN: This was a multicenter prospective cluster-randomized controlled trial comparing FICare and standard care. The primary outcome was length of stay (LOS). Secondary outcomes were nosocomial infections, duration of supplemental oxygen, breastfeeding, and weight gain. Outcomes were compared using univariate and multivariable analyses adjusted for potential confounders and clustering. RESULTS: We enrolled 601 preterm infants from 11 neonatal intensive care units (FICare, n = 298; control, n = 303). The unadjusted LOS was 30.81 vs 30.26 days (mean ratio, 1.02; 95% CI, 0.85-1.22; P = .85). After adjustment, outcomes in the FICare group were improved compared with the control group, including LOS (28.26 vs 35.04 days; mean ratio, 0.81; 95% CI, 0.72-0.91), total medical expenditures (mean ratio, 0.69; 95% CI, 0.53-0.90), weight gain velocity (15.73 vs 10.30 g/day; mean difference, 5.43; 95% CI, 3.65-7.21), duration of supplemental oxygen (13.11 vs 21.42 days; mean difference, 0.71; 95% CI, 0.50-1.00), nosocomial infection rates (4.13 vs 5.84/1000 hospital days; mean ratio, 0.67; 95% CI, 0.47-0.96), antibiotic exposure (38.63 vs 57.32/100 hospital days; mean ratio, 0.67; 95% CI, 0.47-0.96), breastfeeding rates (87.25% vs 55.78%; OR, 5.42; 95% CI, 3.25-9.05), and rehospitalization rates (3.65% vs 7.48%; OR, 0.47; 95% CI, 0.28-0.77). At follow-up to 18 months, breastfeeding rates and weight were significantly (P < .05) higher over time in the FICare group. CONCLUSIONS: FICare was feasible in Chinese neonatal intensive care units and was associated with reduced hospital LOS, medical expenditures, and rates of adverse outcomes.

ETS1 Ameliorates Hyperoxia-Induced Alveolar Epithelial Cell Injury by Regulating the TGM2-Mediated Wnt/ß-Catenin Pathway.

PURPOSE: Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects newborns who need oxygen therapy, and high-concentration oxygen therapy may cause neonatal morbidity and mortality in newborns. E26 oncogene homologue 1 (ETS1) and transglutaminase 2 (TGM2) have been reported to be associated with lung cell injury. However, the mechanism of ETS1 in regulating BPD is still unclear. METHODS: Hyperoxia-induced A549 cells to simulate hyperoxia-induced alveolar epithelial cell injury. MTT assays and colony formation assays were performed to investigate the proliferation of A549 cells. Flow cytometry was carried out to quantify the apoptosis of A549 cells. The expression levels of ETS1 and TGM2 were quantified by qRT-PCR. The protein expression levels of ETS1, TGM2, ß-catenin, c-Jun and MET were measured by western blot. Overexpression of ETS1, overexpression of TGM2, overexpression of ETS1 with downregulation of TGM2 and overexpression of TGM2 with inhibition of Wnt/ß-catenin pathway were performed to investigate the role of ETS1, TGM2 and Wnt/ß-catenin pathways in hyperoxia-induced alveolar epithelial cell injury. RESULTS: Hyperoxia decreased the proliferation and promoted the apoptosis of cells in a time-dependent manner. Moreover, overexpression of ETS1 rescued the effect of hyperoxia on proliferation and apoptosis. In addition, overexpression of TGM2 participated in the regulation of hyperoxia-induced proliferation and apoptosis. ETS1 regulated hyperoxia-induced alveolar epithelial cell injury through the Wnt/ß-catenin pathway via TGM2. CONCLUSION: ETS1 ameliorates hyperoxia-induced alveolar epithelial cell injury through the TGM2-mediated Wnt/ß-catenin pathway.

[A multicenter survey of antibiotic use in very and extremely low birth weight infants in Hunan Province].

OBJECTIVE: To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province. METHODS: The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017. RESULTS: The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (rs=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (rs=0.196, P<0.01). CONCLUSIONS: Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

[Clinical epidemiological characteristics of neonatal respiratory failure: an analysis of 1,108 neonates].

OBJECTIVE: To investigate the clinical epidemiological characteristics of neonatal respiratory failure in 1,108 neonates, and to provide a reference for improvement in clinical treatment and multicenter clinical studies. METHODS: The clinical data of 1,108 neonates with respiratory failure were collected with questionnaires, and statistical analysis was performed for the epidemiological indices including primary diseases, clinical therapeutic methods, treatment outcome, and fatality. RESULTS: In all the neonates with respiratory failure, the median gestational age was 37 weeks+1 day, the median birth weight was 2,600 g, the median age in days on admission to neonatal intensive care unit was 0.71 days (17 hours), and the boy/girl ratio was 3.1:1. The major primary diseases were respiratory distress syndrome (30.51%), pulmonary infection/sepsis (23.55%), and wet lung (13.18%). Of all the neonates, 48.64% received nasal continuous positive airway pressure (nCPAP), 12.81% received high-frequency oscillatory ventilation, 13.45% received pulmonary surfactant, and 8.66% received nitric oxide inhalation therapy. The fatality was 24.19%. CONCLUSIONS: The major primary disease for neonatal respiratory failure is respiratory distress syndrome. Pulmonary surfactant, nCPAP, high-frequency oscillatory ventilation, and nitric oxide inhalation therapy are major therapeutic methods for neonatal respiratory failure, but neonatal respiratory failure still has a high fatality.

[Neurodevelopmental outcomes of extremely low birth weight and very low birth weight infants and related influencing factors].

OBJECTIVE: To investigate the neurodevelopmental outcomes of extremely low birth weight (ELBW) and very low birth weight (VLBW) infants at a corrected age (CA) of 18 months and related factors influencing the outcomes. METHODS: The ELBW and VLBW infants who were admitted to the neonatal intensive care unit, survived, and discharged between January 2013 June 2014 were enrolled. These infants were followed up at CAs of 40 weeks and 1, 3, 6, 12, and 18 months to evaluate the neurodevelopmental outcomes. According to the neurodevelopmental status, the infants were divided into normal and abnormal neurodevelopment groups. The differences in clinical data were compared, and the risk factors for abnormal neurodevelopment in ELBW and VLBW infants were analyzed. RESULTS: A total of 338 ELBW and VLBW infants were enrolled, and 15 died during hospitalization. At the CA of 18 months, 145 infants (44.9%) survived and had complete follow-up data, 75 (23.2%) died, and 103 (31.9%) were lost to follow-up. Of the 145 infants who survived and had complete follow-up data, 71 (49.0%) had neurodevelopmental impairment (NDI), and 3 (2.1%) had cerebral palsy. No infants experienced visual damage with blindness in one or both eyes or hearing loss with a need for hearing aid. The logistic regression analysis showed that bronchopulmonary dysplasia (BDP) (OR=3.530, P<0.001) and sepsis (OR=2.528, P=0.035) were independent risk factors for NDI in ELBW and VLBW infants, and the incidence of NDI increased with the severity of BDP. CONCLUSIONS: Sepsis and BPD, especially severe BPD, are risk factors for NDI in ELBW and VLBW infants.

Validation of the Chinese Empowerment of Parents in the Intensive Care (EMPATHIC-30) Questionnaire Among Parents in Neonatal Intensive Care Units: A Prospective Cross-Sectional Study.

Background: There are no specific validated questionnaires assessing satisfaction of family-centered care experienced by parents of infants hospitalized in Chinese Neonatal Intensive Care Units (NICU). Aim: To adapt and test the reliability and validity of the Chinese version of the EMPATHIC-30 questionnaire in NICU settings. Methods: A prospective, cross-sectional design was adopted. The EMPATHIC-30 questionnaires were completed by parents of infants admitted to one of the four NICUs at Hunan Children's Hospital, China, between November 2018 and 2019. Inclusion criteria were parents whose infants were admitted to the NICU for at least 5 days. Exclusion criteria were parents whose children were discharged within 5 days after admission or whose infants died in the NICU. Reliability was tested with Cronbach's alpha. The congruent validity was tested using Spearman's Rank correlation analysis, and the non-differential validity was tested using Cohen's d. Results: Parents of 619 infants discharged from the NICUs completed and returned the questionnaire. Most infants were male (n = 337, 54.4%) and infants' length of stay was a median of 21 days (IQR = 14-37). Mostly, mothers completed the questionnaire (n = 523, 84.5%). The Cronbach's alpha values of the five individual domains were between 0.67 and 0.95, and the alpha of the total questionnaire was.90, providing an adequate internal consistency. Congruent validity was measured by correlating the five domains with four standard satisfaction scales, documenting a weak correlation (r s -0.025-0.327). Non-differential validity showed some significant effect size between four binary variables (mechanical ventilation, unplanned admission, admission after surgery, length of stay) four of the five domains. Conclusion: The Chinese version of EMPATHIC-30 questionnaire showed acceptable psychometric properties. This instrument might be considered a suitable instrument to measure parent satisfaction among Chinese parents whose infants are admitted to an NICU. Measuring parent satisfaction with this instrument might contribute to improving family-centered care initiatives in NICUs with Chinese parents.

Predicting the developmental outcomes of very premature infants via ultrasound classification: A CONSORT - clinical study.

OBJECTIVE: This study aimed to assess the accuracy of ultrasonic grading in determining brain injury in very premature infants and analyze the affecting factors of these neonatal morbidity and mortality, and to investigate the relationship between serial cranial ultrasound (cUS) classification and Mental Developmental Index (MDI)/Psychomotor Developmental Index (PDI) in premature infants. METHODS: A total of 129 very preterm infants (Gestational Age ≤ 28 weeks) were subjected to serial cUS until 6 months or older and classified into 3 degrees in accordance with classification standards. The MDI and PDI (Bayley test) of the infants were measured until the infants reached the age of 24 months or older. The consistency between Term Equivalent Age (TEA)-cUS and TEA- magnetic resonance imaging (MRI) was calculated. Ordinal regression was performed to analyze the relationship among severe disease, early cUS classifications, psychomotor and mental development, and death. Operating characteristic curve were used to analyze the relationship between serial cUS grades and MDI/PDI scores. RESULTS: The mortality and survival rates of 129 very preterm infants were 32.8% and 67.3%, respectively. Among the 86 surviving infants, 20.9% developed mild cerebral palsy (CP) and 5.8% to 6.9% developed severe CP. The consistency between TEA-cUS and TEA-MRI was 88%. Grades 2 and 3 at first ultrasound were associated with adverse mental (OR = 3.2, OR = 3.78) and motor (OR = 2.25, OR = 2.59) development. cUS classification demonstrated high sensitivity (79%-96%). Among all cUS classifications, the specificity of the first cUS was the lowest and that of TEA-cUS was the highest (57% for PDI and 48% for MDI). CONCLUSIONS: Moderate and severe brain injury at first ultrasound is the most important factor affecting the survival rate and brain development of very premature infants. The cUS classification had high sensitivity and high specificity for the prediction of CP, especially in TEA-cUS.

Mortality and Morbidity of Infants Born Extremely Preterm at Tertiary Medical Centers in China From 2010 to 2019.

Importance: Extreme prematurity is associated with a substantial burden on health care systems worldwide. However, little is known about the prognosis of infants born extremely preterm in developing countries, such as China. Objective: To describe survival and major morbidity among infants born extremely preterm in China over the past decade. Design, Setting, and Participants: This retrospective cohort study was conducted from January 1, 2010, through December 31, 2019. Included individuals were infants with gestational age less than 28 weeks discharged from 1 of 68 neonatal intensive care units located in 31 provinces in China. Data were analyzed from August through October 2020. Exposure: Extremely preterm birth. Main Outcomes and Measures: Survival to discharge and major morbidity (ie, bronchopulmonary dysplasia, grades III-IV intraventricular hemorrhage, white matter injury, stage II-III necrotizing enterocolitis, sepsis, or severe retinopathy of prematurity) were measured. Results: Among 8514 eligible infants, 5295 (62.2%) were male and 116 infants (2.0%) were small for gestational age (SGA). Overall, 5302 infants (62.3%) survived to discharge. The survival rate was 1 of 21 infants (4.8%) at 22 weeks, 13 of 71 infants (18.3%) at 23 weeks, 144 of 408 infants (35.3%) at 24 weeks, 480 of 987 infants (48.6%) at 25 weeks, 1423 of 2331 infants (61.0%) at 26 weeks, and 3241 of 4692 infants (69.1%) at 27 weeks. Survival increased from 136 of 241 infants (56.4%; 95% CI, 50.1%-62.7%) in 2010 to 1110 of 1633 infants (68.0%; 95% CI, 65.7%-70.2%) in 2019 for infants born at 24 to 27 weeks (mean difference, 11.5%; 95% CI, 4.9%-18.2%; P < .001), without a significant change for infants born at less than 24 weeks. Major morbidity was found in 5999 of 8281 infants overall, for a rate of 72.4%, which increased from 116 of 223 infants (52.0%; 95% CI, 45.4%-58.6%) to 1363 of 1656 infants (82.3%; 95% CI, 80.5%-84.1%) from 2010 to 2019 (mean difference, 30.3%; 95% CI, 23.5%-37.1%, P < .001). Regional variations in survival were identified, with an almost 2-fold increase (1.94-fold; 95% CI, 1.66-2.27; P < .001) from 188 of 474 infants (39.7%) in northwest China to 887 of 1153 infants (76.9%) in north China. Gestational age (adjusted risk ratio [aRR], 1.084; 95% CI, 1.063-1.105; P < .001), birth weight (aRR, 1.028; 95% CI, 1.020-1.036; P < .001), premature rupture of membranes (aRR, 1.025; 95% CI, 1.002-1.048; P = .03), and antenatal steroids (aRR, 1.029; 95% CI, 1.004-1.055; P = .02) were associated with improved survival, while being born SGA (aRR, 0.801; 95% CI, 0.679-0.945; P = .01), being male (aRR, 0.975; 95% CI, 0.954-0.997; P = .02), multiple birth (aRR, 0.955; 95% CI, 0.929-0.982; P = .001), having a mother with gestational diabetes (aRR, 0.946; 95% CI, 0.913-0.981; P = .002), and low Apgar score (aRR, 0.951; 95% CI, 0.925-0.977; P < .001) were found to be risk factors associated with decreased chances of survival. Conclusions and Relevance: This study found that infants born extremely preterm were at increased risk of mortality and morbidity in China, with a survival rate that improved over time and a major morbidity rate that increased. These findings suggest that more active and effective treatment strategies are needed, especially for infants born at gestational age 25 to 27 weeks.

Attitudes and concerns of neonatologists and nurses to family-integrated-care in neonatal intensive care units in China.

BACKGROUND: Parents in China are denied visitation of their newborns in neonatal intensive care unit (NICU), leading to a prolonged period of parent-infant separation. The family-integrated care (FICare) model, which supports the integration of parents into the NICU team, is gradually being introduced in China. Considering resistance to the implementation of FICare, this study aimed to assess the attitudes and concerns of neonatologists and nurses towards FICare in China. METHODS: Using a before and after study design, a qualitative analysis was conducted to determine the perceptions and attitudes of medical professionals towards FICare in China. A total of 34 neonatologists and 94 nurses from 5 tertiary NICUs in China were enrolled. A self-developed questionnaire was used. The study steps included reading session and then survey for the first time (survey 1), a FICare getting buy-in education session (4 hours), a group discussion session, and finally repeat the questionnaire (survey 2). The surveys were completed by trained researchers regarding willingness, acceptance and concerns of implementing FICare in NICUs in China. Differences in attitudes towards FICare were compared between groups (Chi-square/correction for continuity). RESULTS: There are positive responses in neonatologists and nurses regarding the necessity (Survey 1: 58.8% and 57.4%; Survey 2: 88.2% and 67.0%), feasibility (Survey 1: 17.6% and 19.1%; Survey 2: 32.3% and 34.0%), and interest in joining FICare (Survey 1: 82.4% and 83.0%; Survey 2: 97.1% and 85.1%). A higher proportion of neonatologists indicated that FICare could promote breastfeeding in the NICU comparing to nurses (Survey 1: 47.1% vs. 19.1%; Survey 2: 61.8% and 46.8% respectively). Most of the neonatologists and nurses are not sure whether FICare can shorten the hospital stay (Survey 1: 82.3% and 68.1%; Survey 2: 85.3% and 60.6%) or improve the doctor-patient relationship (Survey 1: 58.8% and 68.1%; Survey 2: 73.5% and 69.1%). Challenges concerning the implementation of FICare were identified as inadequate ward space, lack of human resources, and potential increases in nosocomial infection. CONCLUSIONS: The getting buy-in education program in introducing new paradigms of neonatal care may help on how to design and implement more effective educational tools for FICare.

Caffeine Citrate for Apnea of Prematurity: A Prospective, Open-Label, Single-Arm Study in Chinese Neonates.

Background: Caffeine citrate has been approved in China for the management of apnea of prematurity. This clinical trial was conducted as a condition of regulatory approval. The aim was to confirm the efficacy of caffeine citrate in the treatment of recurrent intermittent hypoxia and bradycardia in preterm newborns with primary apnea. Objectives: The primary outcome was the change from baseline in the number of apnea events after loading dose administration of caffeine citrate. Secondary efficacy outcomes included the change from baseline in apnea events after 2 and 4 weeks of maintenance doses. Methods: This was a multicenter, prospective longitudinal open-label, single-arm study. Neonates who had experienced at least four apnea events during a 24 h period received a loading dose of caffeine citrate 20 mg/kg; those who required additional maintenance doses received 5 mg/kg/day (titrated up to 10 mg/kg/day in case of insufficient response). The number of apnea events was recorded for 6-12 h prior to the loading dose (baseline), and for 12 h post-dose, following the loading dose and at Weeks 2 and 4 (during maintenance). Results: A total of 247 neonates received the loading dose, who had a significant reduction from baseline of 3.9 events (p < 0.001) in the mean number of apnea events. The subset of neonates who required maintenance doses also had significant reductions in the number of events at all visits (p < 0.001 for all). A total of 79.4% of participants had at least one adverse event, but only one non-serious and no serious events were considered related to treatment. Conclusions: In this large, prospective, open-label study, premature infants with a history of apnea who received caffeine citrate were significantly less likely to experience further apnea events.

[Multicenter follow-up report of 147 premature infants with brain injuries from 6 hospitals in China].

OBJECTIVE: Sponsored by the Subspecialty Group of Neonatology of Pediatric Society, China Medical Association, more than 10 large-scale hospitals participated in the near two-year multicenter investigation for Brain Injuries in Premature Infants in China. The present study presents the follow-up results of 147 premature infants with brain injuries from 6 Third Class A Level hospitals. METHODS: All premature infants with intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL) diagnosed in the early neonatal period in the 6 hospitals were followed-up between January 2005 and August 2006. Based on the synthetic results of physical development, examination of nervous system, intelligence tests and cranial ultrasound, the premature infants with brain injuries were classified as normal development, marginal development and retarded development. RESULTS: One hundred and forty-seven premature infants with brain injuries from the 6 hospitals consisted of 141 cases of IVH and 36 cases of PVL (30 cases having IVH and PVL). Based on the synthetic follow-up results, 51.4% of premature infants with brain injuries were generally assessed as normal development, 38.4% as marginal development and 10.7% as retarded development. Among them, delayed growth in head circumference, height and weight was 13.4%; the occurrence frequency of cerebral paralysis (CP) was 7.1% in PVL grade I, 28.6% in PVL grade II and 100% in PVL grade III; 12.7% showed retarded development of intelligence; and 30% presented post-injurious changes on cranial sonography. CONCLUSIONS: The data of the multicenter follow-up can basically reflect the short-term prognosis of premature infants with brain injuries in major big cities of China. About 10% of them have retarded physical, motor-and mental developments. The long-term regular follow-up study is expected for more premature infants with brain injuries, and behavioral sequelae of brain injuries which may occur in peri-school age and adolescence should be paid particularly close attention.

Predictive Value of Cranial Ultrasound for Neurodevelopmental Outcomes of Very Preterm Infants with Brain Injury.

BACKGROUND: Compared with full-term infants, very preterm infants are more vulnerable to injury and long-term disability and are at high risk of death. The predictive value of ultrasound and imaging on the neurodevelopment is one of the hot topics. This study aimed to investigate the relationship between cranial ultrasound (cUS) variables and neurodevelopmental outcomes of very preterm infants. METHODS: Totally 129 very preterm infants (gestational age ≤28 weeks) in neonatal intensive care unit of Hunan Children's Hospital between January 2012 and November 2014 were included in this retrospective study. Serial cUS (weekly before discharge and monthly after discharge) was performed on the infants until 6 months or older. Magnetic resonance imaging (MRI) was performed on the infants at approximately the term-equivalent age. The mental developmental index (MDI) and psychomotor developmental index (PDI) were followed up until the infants were 24 months or older. The relationship between brain injury and MDI/PDI scores was analyzed. RESULTS: The consistency rate between cUS and MRI was 88%. At the first cUS, germinal matrix hemorrhage (GMH) Grades 3 and 4, hospitalization duration, and weight are significantly correlated with MDI/PDI and prognosis (MDI: odds ratio [OR] = 8.415, 0.982, and 0.042, P = 0.016, 0.000, and 0.004; PDI: OR = 7.149, 0.978, and 0.012, P = 0.025, 0.000, and 0.000, respectively). At the last cUS, gestational age, extensive cystic periventricular leukomalacia (c-PVL), and moderate and severe hydrocephaly are significantly correlated with MDI (OR = 0.292, 60.220, and 170.375, P = 0.004, 0.003, and 0.000, respectively). Extensive c-PVL and moderate and severe hydrocephaly are significantly correlated with PDI (OR = 76.861 and 116.746, P = 0.003 and 0.000, respectively). CONCLUSIONS: Very premature infants with GMH Grades 3 and 4, short hospitalization duration, and low weight have low survival rates and poorly developed brain nerves. Cerebral palsy can result from severe cerebral hemorrhage, moderate and severe hydrocephaly, and extensive c-PVL. The sustained, inhomogeneous echogenicity of white matter may suggest subtle brain injury.

Impact of family integrated care on infants' clinical outcomes in two children's hospitals in China: a pre-post intervention study.

BACKGROUND: Most Neonatal Intensive Care Units (NICUs) in China have restricted visiting policies for parents. This also implicates that parents are not involved in the care of their infant. Family Integrated Care (FIC), empowering parents in direct care delivery and decisions, is becoming the standard in NICUs in many countries and can improve quality-of-life and health outcomes of preterm infants. The aim of this study was to evaluate the impact of a FIC intervention on the clinical outcomes of preterm infants with Bronchopulmonary Dysplasia (BPD). METHODS: A pre-post intervention study was conducted at NICUs in two Chinese children's hospitals. Infants with BPD were included: pre-intervention group (n = 134) from December 2015 to September 2016, post-intervention (FIC) group (n = 115) and their parents from October 2016 to June 2017. NICU nurses were trained between July and September 2016 to deliver the FIC intervention, including parent education and support. Parents had to be present and care for their infant minimal three hours a day. The infants' outcome measures were length-of-stay, breastfeeding, weight gain, respiratory and oxygen support, and parent hospital expenses. RESULTS: Compared with control group (n = 134), the FIC group (n = 115) had significantly increased breastfeeding rates (83% versus 71%, p = 0.030), breastfeeding time (31 days versus 19 days, p < 0.001), enteral nutrition time (50 days versus 34 days, p < 0.001), weight gain (29 g/day versus 23 g/day, p = 0.002), and significantly lower respiratory support time (16 days versus 25 days, p < 0.001). Oxygen Exposure Time decreased but not significant (39 days versus 41 days p = 0.393). Parents hospital expenses in local Chinese RMB currency was not significant (84 K versus 88 K, p = 0.391). CONCLUSION: The results of our study suggests that FIC is feasible in two Chinese NICUs and might improve clinical outcomes of preterm infants with BPD. Further research is needed to include all infants admitted to NICUs and should include parent reported outcome measures. Our study may help other NICUs with limited parental access to implement FIC to enhance parental empowerment and involvement in the care of their infant.

Is family integrated care in neonatal intensive care units feasible and good for preterm infants in China: study protocol for a cluster randomized controlled trial.

BACKGROUND: By changing the paradigm of neonatal intensive care and integrating parents into the care team, the 'family integrated care' (FICare) model developed in Canada ensures that infants receive more consistent care and parents are better able to care for their infants within the neonatal intensive care unit (NICU) and at home. However, Chinese health policy dictates that parents are not allowed into the NICU during their infant's stay, which inhibits this type of parent-infant interaction and may affect infant outcomes. This project aims to demonstrate that allowing parents to care for their newborn infants in the NICU improves the medical outcomes of infants. METHODS/DESIGN: This cluster randomized controlled trial will evaluate the feasibility and efficacy of FICare in six Chinese tertiary-level NICUs in China - three 'intervention' and three 'control' NICUs. The study steps are: (1) planning and preparation; (2) staff recruitment and training; (3) pilot study in two centers; (4) interim analysis and confirmation of sample size for main study; (5) implementation of main study; (6) data analysis and preparation and publication of study reports. The primary outcome measure is duration of hospital stay from admission to discharge. Secondary outcome measures are: (1) clinical outcomes, such as nosocomial infection, (2) weight gain, (3) breastfeeding, (4) time to full feed, and (5) maternal stress. DISCUSSION: This study will assess the feasibility and cost-effectiveness of FICare in China. By establishing that FICare is a practical model of NICU care for stable preterm infants in China, this project will have a significant impact on health outcomes, medical practice and policy, and the cost of medical care. The approach used in this project could be transferable to many other areas of medical care, such as pediatrics, chronic care, and geriatrics. Data in this project can be used to inform health policy in NICUs across China so that parents are allowed to enter the NICU and be at their infant's bedside during the baby's hospitalization, and modifying the design of NICUs in China to facilitate the participation of parents in caring for their newborns.

Mortality and Morbidity of Extremely Low Birth Weight Infants in the Mainland of China: A Multi-center Study.

BACKGROUND: With the progress of perinatal medicine and neonatal technology, more and more extremely low birth weight (ELBW) survived all over the world. This study was designed to investigate the short-term outcomes of ELBW infants during their Neonatal Intensive Care Unit (NICU) stay in the mainland of China. METHODS: All infants admitted to 26 NICUs with a birth weight (BW) < l000 g were included between January l, 2011 and December 31, 2011. All the data were collected retrospectively from clinical records by a prospectively designed questionnaire. The data collected from each NICU transmitted to the main institution where the results were aggregated and analyzed. Categorical variables were performed with Pearson Chi-square test. Binary Logistic regression analysis was used to detect risk factors. RESULTS: A total of 258 ELBW infants were admitted to 26 NICUs, of whom the mean gestational age (GA) was 28.1 ± 2.2 weeks, and the mean BW was 868 ± 97 g. The overall survival rate at discharge was 50.0%. Despite aggressive treatment 60 infants (23.3%) died and another 69 infants (26.7%) died after medical care withdrawal. Furthermore, the survival rate was significantly higher in coastal areas than inland areas (53.6% vs. 35.3%, P = 0.019). BW < 750 g and GA < 28 weeks were the largest risk factors, and being small for gestational age was a protective factor related to mortality. Respiratory distress syndrome was the most common complication. The incidence of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity was 26.2%, 33.7%, 6.7%, 48.1%, and 41.4%, respectively. Ventilator associated pneumonia was the most common hospital acquired infection during hospitalization. CONCLUSIONS: Our study was the first survey that revealed the present status of ELBW infants in the mainland of China. The mortality and morbidity of ELBW infants remained high as compared to other developed countries.

[Clinical analysis of 165 extremely low birth weight infants].

OBJECTIVE: To analyze the clinical features and prognosis of extremely low birth weight infants (ELBWI). METHOD: Data of totally 165 hospitalized ELBWI between August 1st, 2008 and November 30th, 2013 in Hunan Children's Hospital were analyzed. The information of general data and births, prenatal care, delivery room stabilization, transfer information, complications, treatment, outcome and follow up were summarized. RESULT: (1) One hundred and sixty-five ELBWI were involved, their mean gestational age was (28.4±2.4) weeks, mean birth weight(910.9±93.1) g. (2) Rate of delivery in tertiary hospital was 46.7% (77/165) and prenatal steroids exposure was found in 52.1% (86/165). None of the cases were treated with continuous positive airway pressure (CPAP) in delivery room. (3) Rate of infants who were transfered to the class III b neonatal ward within 12 hours after birth was 58.8% (97/165). (4) The main complications of them included neonatal respiratory distress syndrome(NRDS, 77.0%, 127/165), bronchopulmonary dysplasia (BPD, 70.1%, 75/107), patent ductus arteriosus (PDA, 50.0%, 40/80), preterm retinopathy (ROP, 43.0%, 46/107), sepsis 39.4% (65/165), intraventricular hemorrhage (IVH, 34.8%, 49/141), necrotizing enterocolitis (NEC, 8.0%, 7/88). (5) TREATMENT: 97.6% (161/165) received oxygen therapy and 66.1% (109/165) received mechanical ventilation, 55.2% (91/165) used CPAP. 89.8% (114/127) of the NRDS used PS; 44.0% (33/75) of the BPD used low dose dexamethasone, 32.0% (24/75) used low dose nitric oxide; 60.0% (24/40) of the PDA used medication. 32.6% (15/46) of the ROP received laser photocoagulation. The average time of beginning enteral feeding was 2.0 d, the mean time to achieve full gastrointestinal feeding was 43.4 d. (6) OUTCOME: rate of survival in 165 cases with ELBWI was 51.5% (85/165), treatment was abandoned in 37.6% (62/165), total mortality was 48.5% (80/165). There were significant difference in survival rate between different birth weight group, gestational age group and admission age group (χ2=11.498, 8.789, 13.157, all P<0.05); There was significant difference in rate of giving up treatment between different birth weight and admission age groups (χ2=10.448, 8.259, all P<0.05). The primary cause of death was economic factor and worrying about prognosis. (7) Follow up: rate of neurodevelopmental impairment (NDI) in part of follow up cases was 27.9% (12/43). CONCLUSION: ELBWI have many severe complications and sequelae, which need complex treatment and long hospital stay with a low survival rate. In order to improve the level of treatment, we need to improve the rate of prenatal steroids, carry out intrauterine and postnatal, transport of ELBWI to III b neonatal ward as early and rationally as possible, give professional, sophisticated and integrated treatment technologies as far as possible.

Incidence of brain injuries in premature infants with gestational age ≤ 34 weeks in ten urban hospitals in China.

BACKGROUND: There is a large number (1.5 million per year) of premature births in China. It is necessary to obtain the authentic incidences of intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL), the common brain injuries, in Chinese premature infants. The present multicenter study aimed to investigate the incidence of brain injuries in premature infants in ten urban hospitals in China. METHODS: The research proposal was designed by the Subspecialty Group of Neonatology of Pediatric Society of the Chinese Medical Association. Ten large-scale urban hospitals voluntarily joined the multicenter investigation. All premature infants with a gestational age ≤ 34 weeks in the ten hospitals were subjected to routine cranial ultrasound within three days after birth, and then to repeated ultrasound every 3-7 days till their discharge from the hospital from January 2005 to August 2006. A uniform data collection sheet was designed to record cases of brain injuries. RESULTS: The incidences of overall IVH and severe IVH were 19.7% (305/1551) and 4.6% (72/1551), respectively with 18.4% (56/305) for grade 1, 58.0% (177/305) for grade 2, 17.7% (54/305) for grade 3 and 5.9% (18/305) for grade 4 in nine hospitals. The incidences of overall PVL and cystic PVL were 5.0% (89/1792) and 0.8% (14/1792) respectively, with 84.3% (75/89) for grade 1, 13.5% (12/89) for grade 2, and 2.2% (2/89) for grade 3 in the ten hospitals. The statistically significant risk factors that might aggravate the severity of IVH were vaginal delivery (OR=1.883, 95% CI: 1.099-3.228, P=0.020) and mechanical ventilation (OR=4.150, 95% CI: 2.384-7.223, P=0.000). The risk factors that might result in the development of cystic PVL was vaginal delivery (OR=21.094, 95% CI: 2.650-167.895, P=0.000). CONCLUSIONS: The investigative report can basically reflect the incidence of brain injuries in premature infants in major big cities of China. Since more than 60% of the Chinese population live in the rural areas of China, it is expected to undertake a further multicenter investigation covering the rural areas in the future.

Development of neonatal respiratory and intensive care: Chinese perspectives.

Recent economic improvements in China have allowed the development of perinatal-neonatal care in sub-provincial regions. However, variations in neonatal respiratory and intensive care exist, especially in regions with limited resources. We conducted a series of collaborative clinical investigations into neonatal hypoxemic respiratory failure (NRF). In the study period from 2004 to 2005, this nationwide study found an incidence of NRF of 13.4% of total admissions to neonatal intensive care units (NICUs), with a mortality of 32%. Fewer than 30% of infants with respiratory distress syndrome (RDS) received surfactant treatment. Most cases of NRF had birth weights (BWs) of 1,000-1,500 g. Approximately 60% of deaths were due to withdrawal of respiratory support because of economic restraints despite initial response to therapy. Extremely low BW or gestational age accounted for less than 2% of all NRF cases, and their survival rate was less than 50%. A prospective clinical epidemiologic study of NRF in 14 NICUs, mainly sub-provincial centers, in Hebei province was undertaken in the study period from 2007 to 2008. NRF made up 16.9% of total NICU admissions, with increased use of surfactant (>50%) and continuous positive airway pressure (>80%) in this study. However, mortality due to RDS, meconium aspiration syndrome and pulmonary infection/sepsis remained higher than 30%, in part affected by socioeconomic factors. With measures to assist hospitalized neonates from low income families in urban areas, as well as the 'new rural cooperative health care program' to subsidize families from rural areas, the quality and affordability of NICU services may be improved in the forthcoming years.
