Barriers and Facilitators of Parent Presence in the Neonatal Intensive Care Unit.

The purpose of this study was to describe system-level and personal factors influencing parent presence in the neonatal intensive care unit (NICU) and identify differences in factors by sociodemographic characteristics. In a cross-sectional national survey study using social media recruitment, participants rated the frequency of 13 potential barriers and 12 potential facilitators using a 5-point Likert scale. Experiences of discrimination and parent-staff engagement were also measured. Valid responses were analyzed from 152 participants. Uncomfortable facilities and home responsibilities were the most highly reported system-level and personal barriers, respectively. Encouragement to participate in caregiving and social support were the most highly reported system-level and personal facilitators, respectively. Participants reported low to moderate levels of discrimination and moderate levels of parent-staff engagement. Latent class analysis revealed three sociodemographic clusters. Differences in barriers, facilitators, discrimination, and engagement were found among clusters. NICU facilities are uncomfortable and may discourage parent presence. Allowing support persons to accompany parents, providing comfortable facilities, and engaging parents in caregiving may promote greater parent presence and improved parent and child outcomes. Studies of potential bias toward parents with lower education and income and effects on parent presence and infant outcomes are needed.

Risk factors and trends in neonatal mortality in NICU in a tertiary care hospital in India

Introduction: The most vulnerable period of human life is neonatal period, which accounts for most of the morbidities and mortalities. Most of them are preventable with adequate health-care facilities. Objectives: The aim of the study was to determine the trends of neonatal mortality and identify the risk factors, most of which are preventable and measure the progress of health-care services. Methods: A retrospective study was conducted in neonatal intensive care unit (NICU) of Al-Ameen Children Hospital (AMCH) Vijayapura, Karnataka, India. Data were extracted from paper medical records at AMCH of a period of 1 year and digitized. Data obtained included age, sex and birth weight, place of delivery, morbidity profile, mortality profile, diagnosis, and period of stay in NICU. Results: A total of 648 neonates were admitted in NICU during the study period of 1-year duration, between January and December 2021. A total of 382 (58.9%) infants were discharged on recovery, 65 (10.3%) were referred due to unavailability of advanced surgical intervention, 39 (6%) were discharged against medical advice, 162 (25%) died due to various reasons. Male neonatal deaths outnumbered female neonates (56.8%). Among the total neonatal deaths, 82 (50.6%) were preterm neonates, 73 (45.1%) were term neonates and 7 (4.3%) were post-term neonates. It was noticed that among neonatal deaths, 87 (54.3%) babies were out-born and 75 (46.2%) babies were inborn. In this study, it was noticed that the mortality percentage of the neonate falling in the category of 1.5–1.9 kg was high compared to other categories. In our study, respiratory distress syndrome was the main cause of mortality accounting for 19.1% (31 cases) of total cases and prematurity was the most common risk factor. Conclusion: Improving the standard of antenatal care and encouraging deliveries in institutions having good NICU facility and early identification of risk factors help to reduce the mortality and its complications.

Comparing Opioid with Opioid-free Anesthesia Technique in Neonates Undergoing Tracheoesophageal Fistula Repair.

Tracheoesophageal fistula (TEF) is a congenital disorder that presents as a surgical emergency in neonates. In regions where neonatal intensive care unit facilities and resources are inadequate and skilled personnel are scarce, not extubating neonates on table, contributes to mortality. Our aim was to assess and compare the on-table extubation rate, extubation time, and postoperative pain scores between opioid and opioid-free anesthesia techniques in neonates undergoing surgical repair of TEF. We conducted a prospective, single-blind, randomized trial over 18 months between January 2021 and June 2022 in Safdarjung Hospital, New Delhi on 60 full-term neonates scheduled for TEF surgeries randomly allocated to two groups according to the mode of analgesia administered. Group O were given fentanyl injection 1 µg/kg intravenous (IV) loading dose with IV injection. acetaminophen at 7.5 mg/kg and top-up of 0.25 µg/kg fentanyl IV si opus sit. Group NO were given pre-surgical local infiltration and intercostal block with 0.25% and 0.5% bupivacaine, respectively, with IV acetaminophen at 7.5 mg/kg. Mean age in days, gender distribution, and weight in both groups were statistically comparable. The difference in the number of neonates extubated on table was statistically significant (p =0.002) in group NO compared to group O. Lower mean extubation time was seen in group NO (9.0 min 40.0 secs±3.0 min 3.0 secs) compared to group O (16.0 min 45.0 secs±8.0 min 5.0 secs) (p < 0.001). There was a statistically significant (p =0.010) lower Neonatal Infant Pain Scale score in group NO with mean and SD as 1.8±0.8 compared with group O, 2.5±1.1 at 90 min. In neonates undergoing TEF repair, opioid-free anesthesia is a safe and effective method, providing a better extubation rate, faster time to extubation, and better postoperative pain control.

Providing value to patients and providers via a pediatric statewide antibiogram in South Carolina.

Antimicrobial stewardship has special challenges in particular populations and facilities, including pediatrics. We sought to augment the information available to antimicrobial stewardship programs (ASPs) by created a cumulative statewide antibiogram for neonatal and pediatric populations. In the Antimicrobial Stewardship Collaborative of South Carolina (ASC-SC), we created statewide antibiograms, including a separate antibiogram accounting for the pediatric and neonatal intensive care unit (NICU) populations. We collated data from the 4 pediatric and 3 NICU facilities in the state to provide a cumulative statewide antibiogram. Methicillin-susceptible Staphylococcus aureus was more prevalent than methicillin-resistant Staphylococcus aureus. Pseudomonas aeruginosa, Citrobacter koserii, and Acinetobacter baumannii were isolated in only 1 NICU. These antibiograms should improve empiric prescribing in both the inpatient and outpatient setting, providing data in some areas that historically do not have pediatric antibiogram to inform prescribing. The antibiogram alone is not sufficient independently to improve prescribing but is one important aspect of stewardship in the pediatric population of South Carolina.

A Prospective Study of Maternal and Perinatal Outcomes in Eclampsia in a Tertiary Care Centre

Background: The term eclampsia is derived from a Greek word, meaning like a flash of lightening. The onset of convulsions in a woman with pre-eclampsia that cannot be attributed to other causes is termed eclampsia. It is a major cause of maternal and fetal mortality and morbidity in our country. The management of eclampsia is still challenging to the obstetrician, requiring the greatest skill, judgement, and patience. Methods and Materials: Our study is an observational and prospective study of 58 cases admitted with eclampsia in Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sewagram. The study was extended from January 2020 to December 2021. The inclusion criteria were all the cases of eclampsia (antepartum and postpartum), primigravida and multigravida, duration of gestation&gt;20 weeks. Patients with convulsion during pregnancy or in puerperal period attributed to epilepsy or other causes were excluded from the study. Results: In our study majority of cases (58.6 %) belong to the younger age group /= 37 weeks). 55.2% had antepartum eclampsia, 36.2% postpartum and 8.6% had intrapartum eclampsia. Most common complication observed was need of blood or blood products transfusion (35 %), Hemolysis, Elevated Liver Enzymes Low Platelets (HELLP) syndrome (21%), prolonged Intensive Care Unit (ICU) admission (19%) followed by abruption, Disseminated Intravascular Coagulation (DIC), Acute Kidney Injury (AKI), Posterior Reversible Encephalopathy Syndrome (PRES), hypertensive retinopathy, pulmonary edema. Majority of patients (57%) underwent cesarean section, most common indication being poor bishop’s score with deteriorating maternal condition (54.5%). Out of 58 cases, 84.4% were live births and 15.6% were still born. 63.2% of all live births were small for gestational age, 44.8% had Neonatal Intensive Care Unit (NICU), and 8% had early neonatal death. Conclusion: Early pregnancy registration, good antenatal care and counselling about warning symptoms, early identification of pre-eclampsia and its complications, and timely intervention can reduce the incidence of eclampsia. Early identification of high-risk cases at primary healthcare facilities including severe pre-eclampsia, impending eclampsia and eclampsia and immediate referral to tertiary care centre equipped with multidisciplinary team, ICU and NICU facilities, might reduce fetal morbidities like prematurity, neonatal intensive care unit admission etc. and maternal morbidities like prolonged hospitalisation, AKI, DIC , pulmonary edema, multi organ dysfunction syndrome etc. and mortality.

BACKGROUND One of the most common complications of pregnancy is preeclampsia, characterized by abnormal placental development, leading to inadequate uteroplacental blood flow. Doppler ultrasonography can pick up these abnormalities; thus, it is a useful tool to assess fetal outcome. Objective is to calculate the role of colour Doppler (umbilical and middle cerebral artery) in predicting the perinatal outcome. We wanted to evaluate the application of Doppler ultrasound in analysing the blood flow velocity waveform. METHODS This was a cross sectional study carried out between May 2010 - November 2012 in Obstetrics Department, Yenepoya Medical College, Karnataka, among 150 pregnant women with preeclampsia. RESULTS 49.3 % of patients belonged to 25 - 30 years, 58.7 % were primigravida, and 73.3 % and 26.7 % had mild and severe preeclampsia respectively. Patients with increased resistance umbilical artery Doppler - 63.8 % had babies &lt; 2.5 Kg birth weight, 60.9 % Apgar &lt; 7 at 5 minutes of birth and 67.5 % neonatal intensive care unit (NICU) admissions; absent end diastolic flow - all had birth weight &lt; 2 Kg, 90 % Apgar &lt; 7 at 5 minutes, 1 neonatal death and all required NICU admissions; reversal end diastolic flow - 1 neonatal death, all had birth weight &lt; 2.5 Kg, an Apgar &lt; 7 at 5 minutes and required NICU admission. Patients with abnormal Doppler in middle cerebral artery, 46.2 % were low birth weight and had Apgar &lt; 7 at 5 minutes, 50 % required NICU admissions, but no perinatal mortality. CONCLUSIONS Doppler analysis helps in early detection of uteroplacental and fetoplacental changes and to take decisions for early interventions, like administration of steroids for fetal lung maturity and transferring preterm pregnancies to higher centres for better NICU facilities. Umbilical artery Doppler findings are slightly better predictors of adverse perinatal outcome than an abnormal middle cerebral artery.

Statistical Evaluation of the First Year of a Neonatal Intensive Care Unit Established in a Medical School Hospital.

There has been significant progress in reducing perinatal mortality in Japan. However, due to changes in social conditions, the total fertility rate and the number of births are decreasing, whereas the number of low birth weight infants is increasing along with the number of newborn babies that require intensive care. Further, although the number of high-level perinatal medical centers has increased, so has that of infants who need long-term hospitalization. Conversely, the number of regular obstetric facilities has decreased, thus resulting in insufficient beds for neonatal care. To fill this gap, we established a neonatal intensive care unit (NICU) at our hospital. This study aimed to evaluate our new type by comparing the data from ours with that from other facilities. The other facilities assessed were two high-level NICU facilities and two regular obstetric facilities. Data, including sex, gestational age, birth weight, Apgar scores at 1 and 5 min, delivery method, and presence of breathing disorders, were extracted from medical records. The birth weight and gestational age distributions were significantly different in the institutions, except in one facility without a NICU. The new NICU saw more infants with low birth weight and respiratory disorders than the regular obstetric facilities. The comparison of birth weight and gestational age distributions, cases of respiratory disorders, and delivery methods indicate that our new NICU is positioned as an intermediate facility between a high-level NICU and a regular obstetrics facility.

Presence of neonatal intensive care services at birth hospital and early intervention enrollment in infants ≤1500 g.

Objectives To determine whether the receipt of therapeutic services of very-low-birth-weight (VLBW; ≤1500 g) neonates inadvertently delivered at community Level 2 and 3 neonatal intensive care units (NICUs) compared with those born at a well-baby nursery (WBN; Level 1) differed. Methods This is a retrospective study of neonates who were born at Level 1 (WBN), 2, 3, and 4 NICUs and discharged from a Level 4 hospital (n = 529). All infants were evaluated at the Regional Neonatal Follow-up Program at 12 ± 1 months corrected gestational age (CA) and assessed for use of therapeutic services including: early intervention (EI), occupational therapy (OT), physical therapy (PT), speech therapy (ST), and special education (SE). Results Compared to infants born at community Level 2 and 3 NICU hospitals, those outborn at a community Level 1 WBN had significantly higher utilization of EI (90% vs. 62%) and PT (83% vs. 61%) at 12 months CA. This association persisted when controlling for covariates. Infants who required EI had significantly lower Bayley-III cognitive scores at 3 years of age. Conclusion VLBW infants outborn at WBN (Level 1) hospitals required more outpatient therapeutic services than those born at hospitals with NICU facilities. These results suggest that delivering at the appropriate community hospital level of care might be advantageous for long-term outcomes.

Prophylactic Dexamethasone for improving perinatal outcome before elective caesarean section at term pregnancy

Background and objectives: With the increase in the incidence of elective caesarean section, and the absence of onset of labour, the increase in the rate of neonatal respiratory morbidities and admissions to neonatal intensive care unit have also been observed. The objective of the study is to evaluate the role of prophylactic dexamethasone in reducing the occurrence of neonatal respiratory morbidities in term pregnancies before elective caesarean section. Methods: The study was a prospective cohort study conducted at Maternity Teaching Hospital at Erbil – Iraq from first Septem- ber 2017 till first of September 2018, 400 term pregnant ladies scheduled for elective caesarean section divided to 200 women who received prophylactic 4 doses of 6 mg dexamethasone, and 200 women who received nothing. We compare the incidence of admissions to neonatal intensive care unit, respiratory distress syndrome, transient tachypnea of newborn and early neonatal death between the two groups. Results: Dexamethasone group showed lower incidences of admissions to neonatal intensive care unit 3.5 % and transient tachypnea of newborn 2.5% than control group 10.5% and 7 % respectively with statistically significant differences between them, using Chi-square test. Respiratory distress syndrome and an early neonatal death have lower incidences in dexamethasone group 2.5% and 0% than control group 3.5% and 1% respectively, but statistically were not significant. Conclusions: The use of prophylactic antenatal corticosteroid was found significantly to reduce neonatal respiratory morbidities and admissions to neonatal intensive care unit, especially in our center with low neonatal intensive care unit facilities.

Morbidity and mortality outcomes in neonates who were transferred from home and hospitals to the only neonatal intensive care unit in Guinea: a descriptive report using routinely collected health data.

The Sustainable Development Goal (SDG) for neonatal mortality has identified its reduction as one of the main targets to be achieved by 2030. We provide a descriptive report on neonatal outcomes from the only neonatal intensive care unit (NICU) in Guinea. Data collection took place between November 2004 and May 2005 at the NICU of the Institute of Child Health in the capital, Conakry. A descriptive summary of the neonatal, maternal and intrapartum characteristics is reported. A total of 294 neonates were admitted to the NICU incubators during the study period, transferred either from hospitals (48%) or directly from their homes (52%). The most common reasons for admission were foetal distress (37.1%) and maternal-foetal infections (35.4%). Among 270 neonates with known outcome, the overall mortality among the admitted children remained high at 20.7% (56/270),with a large proportion of the deaths (71.4%, 40/56) occurring within 7 d of their admission. The mortality rate was 23.7% (31/131) among the neonates who were admitted to our NICU after home birth and 17.9% (25/139) among those who were transferred from hospitals (OR: 1.41, 95% CI: 0.75-2.67). Almost one in every five neonates who were admitted to the NICU incubator died during the study period. More hospitals equipped with NICU facilities are urgently required if Guinea is to achieve the SDG target for neonatal mortality.

Sleep-wake cycle on amplitude-integrated EEG and neuroimage outcomes in newborns.

BackgroundThe aim of this study was to evaluate the results of sleep-wake cycle monitoring using amplitude-integrated EEG (aEEG) and neuroimaging in newborn infants with a possible perinatal hypoxic insult, investigate the correlation between the findings, and determine the relevance of the findings to reasonably predict neurological outcome.MethodsaEEG was recorded among newborn infants suspected of perinatal asphyxia between November, 2014 and June, 2015 in one neonatal intensive care unit facility. Brain imaging with serial ultrasonography and MRI when available were performed, and the infants were divided into two groups according to findings and potential neurological outcome: Group I (favorable findings) and Group II (severe findings such as high grade intraventricular hemorrhage, cerebral infarction or white matter injury). Established sleep-wake cycle times after birth was compared between the two groups.ResultsAmong 107 newborn infants, 85 subjects were classified as Group I and the remaining 22 subjects as Group II. The total number of aEEG sessions was 207 and recording time was 2,796 h with a mean of 14.43 ± 13.40 h per study. Estimated times of cyclicity were earlier in Group I (113.34 h, 95 % CI 82.31–144.37) as compared to Group II (504.39 h, 95 % CI 319.91–688.88; p < 0.001).ConclusionsDelayed cyclicity on aEEG has a strong correlation with unfavorable brain neuroimages in newborns with possible perinatal asphyxia. If sleep-wake cycles do not appear during initial period after birth, follow-up aEEG studies are recommended.Trial registrationRetrospectively registeredRegistration number: BD 2015–148Name of registry: amplitude integrated EEG in neonateDate of registration: September 9, 2015

Neonatal pneumonia in sub-Saharan Africa.

Neonatal pneumonia is a devastating condition. Most deaths in sub-Saharan Africa can be attributed to preventable diseases, including pneumonia, diarrhoea and malaria, which together killed an estimated 2.2 million children under the age of 5 years in 2012, accounting for a third of all under-five deaths in this region. Some countries are making progress in reducing mortality through community-based health schemes; however, most countries in this region are far from achieving the World Health Organization Sustainable Development Goals for reducing childhood morbidity and mortality. The microorganisms causing neonatal pneumonia are well known. Both bacteria and viruses are commonly responsible, while fungal organisms occur in the context of nosocomial disease, and parasites occur in HIV-infected children. The common bacterial pathogens are group B streptococci (and other streptococcal species) and Gram-negative organisms, most notably Escherichia coli and Klebsiella spp. The viruses that predominate are the common respiratory pathogens, namely respiratory syncytial virus, human rhinovirus, and influenza virus. Viral disease is often nosocomial and transmitted to infected neonates in the neonatal intensive care unit or other neonatal facilities by infected parents and staff. Neonatal pneumonia often presents with non-specific respiratory distress in newborns. In the premature infant it is often indistinguishable from surfactant deficiency-associated respiratory distress syndrome. Therefore, diagnostic testing that is cheap and reliable is urgently sought in this region. All neonates with pneumonia must receive broad-spectrum antibiotic cover. This usually entails the combination of penicillin and an aminoglycoside. A lack of appropriate drugs and neonatal intensive care unit facilities are hampering progress in managing neonatal pneumonia.

Epidemiologic Research on Malformations Associated with Cleft Lip and Cleft Palate in Japan.

To investigate malformations associated with cleft lip and cleft palate, we conducted surveys at neonatal intensive care units (NICUs) and other non-NICU facilities and to determine whether there are differences among facilities. The regional survey investigated NICU facilities located in Oita Prefecture, including 92 patients with cleft lip and palate (CLP) or cleft palate (CP) that occurred between 2004 and 2013, and the national survey investigated oral surgery, plastic surgery, and obstetrics and gynecology facilities located in Japan, including 16,452 patients with cleft lip (CL), CLP, or CP that occurred since 2000. The incidence per 10,000 births was 4.2, 6.2, and 2.8 for CL, CLP, and CP, respectively, according to the national survey, and 6.3 and 2.9 for CLP and CP, respectively according to the regional survey. These results indicated comparable incidences between the two surveys. In contrast, when the survey results on malformations associated with CLP and CP according to the ICD-10 classification were compared between the national survey conducted at oral surgery or plastic surgery facilities and the regional survey conducted at NICU facilities, the occurrence of associated malformations was 19.8% vs. 41.3% for any types of associated malformation, 6.8% vs. 21.7% for congenital heart disease, and 0.5% vs. 16.3% for chromosomal abnormalities. These results indicated that the incidences of all of these associated malformations were significantly greater in the survey conducted at NICU facilities and similar to the findings from international epidemiological surveys. When comparing the survey conducted at obstetrics facilities vs. NICU facilities, the occurrence of associated malformations was similar results as above. The incidence of CLP and CP was not different between surveys conducted at NICU facilities vs. non-NICU facilities; however, when conducting surveys on associated malformations, it is possible to obtain accurate epidemiological data by investigating NICU facilities where detailed examinations are thoroughly performed.

Nifedipine versus atosiban in the treatment of threatened preterm labour (Assessment of Perinatal Outcome after Specific Tocolysis in Early Labour: APOSTEL III-Trial)

BackgroundPreterm birth is the most common cause of neonatal morbidity and mortality. Postponing delivery for 48 hours with tocolytics to allow for maternal steroid administration and antenatal transportation to a centre with neonatal intensive care unit facilities is the standard treatment for women with threatening preterm delivery in most centres. However, there is controversy as to which tocolytic agent is the drug of first choice. Previous trials have focused on tocolytic efficacy and side effects, and are probably underpowered to detect clinically meaningfull differences in neonatal outcome. Thus, the current evidence is inconclusive to support a balanced recommendation for clinical practice. This multicenter randomised clinical trial aims to compare nifedipine and atosiban in terms of neonatal outcome, duration of pregnancy and maternal side effects.Methods/DesignThe Apostel III trial is a nationwide multicenter randomised controlled study. Women with threatened preterm labour (gestational age 25 – 34 weeks) defined as at least 3 contractions per 30 minutes, and 1) a cervical length of ≤ 10 mm or 2) a cervical length of 11-30 mm and a positive Fibronectin test or 3) ruptured membranes will be randomly allocated to treatment with nifedipine or atosiban. Primary outcome is a composite measure of severe neonatal morbidity and mortality. Secondary outcomes will be time to delivery, gestational age at delivery, days on ventilation support, neonatal intensive care (NICU) admittance, length admission in neonatal intensive care, total days in hospital until 3 months corrected age, convulsions, apnoea, asphyxia, proven meningitis, pneumothorax, maternal side effects and costs. Furthermore, an economic evaluation of the treatment will be performed. Analysis will be by intention to treat principle. The power calculation is based on an expected 10% difference in the prevalence of adverse neonatal outcome. This implies that 500 women have to be randomised (two sided test, β 0.2 at alpha 0.05).DiscussionThis trial will provide evidence on the optimal drug of choice in acute tocolysis in threatening preterm labour.Trial registrationClinical trial registration: NTR2947, date of registration: June 20th 2011.

The Impact of Neonatal Care Resources on Regional Variation in Neonatal Mortality Among Very Low Birthweight Infants in Korea

Faced with extremely low fertility rates and increasing numbers of low-birthweight births in Korea, we examined the factors affecting the mortality of very-low-birthweight (VLBW) infants in Korea. A survey was conducted in 91 of 93 hospitals providing neonatal intensive care in Korea in 2009. Data included information on number of neonatal intensive care unit (NICU) beds, medical workforce, resources in the NICU, birth and death. There was approximately one NICU per 4888 births, one NICU bed per 355 births, one mechanical ventilator per 739 births, one incubator per 327 births and one board-certified neonatologist per 4683 births. Regional disparity existed in neonatal care resources and consequently in mortality rates. VLBW infants' mortality was related to the NICU facility level, volume of VLBW infants and geographic regions. The capital city, Seoul, has the best NICU facilities and workforce, and the least mortality. Overall mortality rates before hospital discharge for <750, 750-999 and 1000-1499 g were 44.8%, 20.4% and 6.5% respectively. There was a two to threefold difference in the mortality rates across the regions. However, following adjustments for NICU facility level and volume of VLBW infants admissions, regional difference in mortality rates was markedly reduced in the <750 g and disappeared in the larger VLBW groups. Regional disparity in mortality of VLBW infants in Korea is most marked in the lowest-birthweight group, <750 g. This disparity is primarily due to lack of resources for neonatal intensive care in most of provincial areas.

Bacterial Diversity in Two Neonatal Intensive Care Units (NICUs)

Infants in Neonatal Intensive Care Units (NICUs) are particularly susceptible to opportunistic infection. Infected infants have high mortality rates, and survivors often suffer life-long neurological disorders. The causes of many NICU infections go undiagnosed, and there is debate as to the importance of inanimate hospital environments (IHEs) in the spread of infections. We used culture-independent next-generation sequencing to survey bacterial diversity in two San Diego NICUs and to track the sources of microbes in these environments. Thirty IHE samples were collected from two Level-Three NICU facilities. We extracted DNA from these samples and amplified the bacterial small subunit (16S) ribosomal RNA gene sequence using ‘universal’ barcoded primers. The purified PCR products were pooled into a single reaction for pyrosequencing, and the data were analyzed using QIIME. On average, we detected 93+/−39 (mean +/− standard deviation) bacterial genera per sample in NICU IHEs. Many of the bacterial genera included known opportunistic pathogens, and many were skin-associated (e.g., Propionibacterium). In one NICU, we also detected fecal coliform bacteria (Enterobacteriales) in a high proportion of the surface samples. Comparison of these NICU-derived sequences to previously published high-throughput 16S rRNA amplicon studies of other indoor environments (offices, restrooms and healthcare facilities), as well as human- and soil-associated environments, found the majority of the NICU samples to be similar to typical building surface and air samples, with the notable exception of the IHEs which were dominated by Enterobacteriaceae. Our findings provide evidence that NICU IHEs harbor a high diversity of human-associated bacteria and demonstrate the potential utility of molecular methods for identifying and tracking bacterial diversity in NICUs.

Conhecimento e percepção dos profissionais a respeito do ruído na unidade neonatal

O objetivo deste estudo foi verificar o conhecimento e a percepção de profissionais de Unidade de Terapia Intensiva Neonatal (UTIN) sobre as repercussões do ruído ao neonato, família e profissionais, antes da implementação de um programa educativo. Trata-se de uma pesquisa descritiva, quantitativa, realizada em Unidade de Terapia Intensiva Neonatal de um hospital de São Paulo, com 101 profissionais. Foram utilizados: questionário para a coleta de dados, e os testes de Qui-quadrado e t de Student para a associação entre as variáveis. Os profissionais identificaram a UTIN como muito ruidosa (44,9%), perceberam os efeitos desse ruído durante e após a jornada de trabalho (67,4%) e utilizaram estratégias para amenizá-lo. Embora os profissionais desconheçam a legislação sobre o ruído no ambiente hospitalar, identificaram repercussões para si, recém-nascido e família. Os resultados apontaram para a necessidade de orientar a equipe quanto à legislação, prevenção de ruído e reorganização das práticas assistenciais e estrutura física da Unidade de Terapia Intensiva Neonatal.

Vigorous cleaning and adequate ventilation are necessary to control an outbreak in a neonatal intensive care unit

An outbreak of Bacillus cereus (B. cereus) bacteremia occurred in our neonatal intensive care unit (NICU) in July 2005. Many strains of B. cereus were cultured from patient specimens, as well as from environmental samples such as the surfaces of instruments and air in the NICU. Some of these strains were analyzed by pulsed field gel electrophoresis, and several were confirmed to be identical. We speculated that the bacterial load in the environment had initially increased and then possibly spread throughout the NICU facility via the airflow of the ventilation system. For this reason, besides maintaining standard precautions, we performed a vigorous clean of the NICU, and covered the vents to prevent dust falling from them. These protective measures ended the outbreak. In the hospital environment, adequate ventilation is important, especially in single-occupancy isolation rooms and operating theaters. However, the criteria for the adequate ventilation of multioccupancy rooms for acute care environments such as the NICU have not yet been defined. We need to pay more attention to these environmental factors in order to avoid cross contamination and infectious outbreaks.

A Comparison of Parent Satisfaction in an Open-Bay and Single-Family Room Neonatal Intensive Care Unit

The purpose of this research was to test the hypothesis that parental satisfaction with neonatal intensive care is greater in a single-family room facility as compared with a conventional open-bay neonatal intensive care unit (NICU). This investigation was a prospective cohort study comparing satisfaction survey results for parents who responded to a commercially available parent NICU satisfaction survey following the provision of NICU care in open-bay and single-family room facilities. A subset of 16 items indicative of family-centered care was also computed and compared for these two NICU facilities. Parents whose babies received care in the single-family room facility expressed significantly improved survey responses in regard to the NICU environment, overall assessment of care, and total survey score than did parents of neonates in the open-bay facility. With the exception of the section on nursing in which scores in both facilities were high, nonsignificant improvement in median scores for the sections on delivery, physicians, discharge planning, and personal issues were noted. The total median item score for family-centered care was significantly greater in the single-family room than the open-bay facility. Parental satisfaction with care in the single-family room NICU was improved in comparison with the traditional open-bay NICU. The single-family room environment appears more conducive to the provision of family-centered care. Improved parental satisfaction with care and the potential for enhanced family-centered care need to be considered in decisions made regarding the configuration of NICU facilities in the future.

The role of outpatient facilities in explaining variations in risk-adjusted readmission rates between hospitals.

Validate risk-adjusted readmission rates as a measure of inpatient quality of care after accounting for outpatient facilities, using premature infants as a test case. Surviving infants born between January 1, 1998 and December 12, 2001 at five Northern California Kaiser Permanente neonatal intensive care units (NICU) with 1-year follow-up at 32 outpatient facilities. Using a retrospective cohort of premature infants (N=898), Poisson's regression models determined the risk-adjusted variation in unplanned readmissions between 0-1 month, 0-3 months, 3-6 months, and 3-12 months after discharge attributable to patient factors, NICUs, and outpatient facilities. Prospectively collected maternal and infant hospital data were linked to inpatient, outpatient, and pharmacy databases. Medical and sociodemographic factors explained the largest amount of variation in risk-adjusted readmission rates. NICU facilities were significantly associated with readmission rates up to 1 year after discharge, but the outpatient facility where patients received outpatient care can explain much of this variation. Characteristics of outpatient facilities, not the NICUs, were associated with variations in readmission rates. Ignoring outpatient facilities leads to an overstatement of the effect of NICUs on readmissions and ignores a significant cause of variations in readmissions.
