Burden of disease and risk factors for mortality amongst hospitalized newborns in Nigeria and Kenya.

OBJECTIVE: To describe the patient population, priority diseases and outcomes in newborns admitted <48 hours old to neonatal units in both Kenya and Nigeria. STUDY DESIGN: In a network of seven secondary and tertiary level neonatal units in Nigeria and Kenya, we captured anonymised data on all admissions <48 hours of age over a 6-month period. RESULTS: 2280 newborns were admitted. Mean birthweight was 2.3 kg (SD 0.9); 57.0% (1214/2128) infants were low birthweight (LBW; <2.5kg) and 22.6% (480/2128) were very LBW (VLBW; <1.5 kg). Median gestation was 36 weeks (interquartile range 32, 39) and 21.6% (483/2236) infants were very preterm (gestation <32 weeks). The most common morbidities were jaundice (987/2262, 43.6%), suspected sepsis (955/2280, 41.9%), respiratory conditions (817/2280, 35.8%) and birth asphyxia (547/2280, 24.0%). 18.7% (423/2262) newborns died; mortality was very high amongst VLBW (222/472, 47%) and very preterm infants (197/483, 40.8%). Factors independently associated with mortality were gestation <28 weeks (adjusted odds ratio 11.58; 95% confidence interval 4.73-28.39), VLBW (6.92; 4.06-11.79), congenital anomaly (4.93; 2.42-10.05), abdominal condition (2.86; 1.40-5.83), birth asphyxia (2.44; 1.52-3.92), respiratory condition (1.46; 1.08-2.28) and maternal antibiotics within 24 hours before or after birth (1.91; 1.28-2.85). Mortality was reduced if mothers received a partial (0.51; 0.28-0.93) or full treatment course (0.44; 0.21-0.92) of dexamethasone before preterm delivery. CONCLUSION: Greater efforts are needed to address the very high burden of illnesses and mortality in hospitalized newborns in sub-Saharan Africa. Interventions need to address priority issues during pregnancy and delivery as well as in the newborn.

Evaluating services for perinatal asphyxia and low birth weight at two hospitals in Ghana: a micro-costing analysis.

BACKGROUND: Neonatal mortality has been decreasing slowly in Ghana despite investments in maternal-newborn services. Although community-based interventions are effective in reducing newborn deaths, hospital-based services provide better health outcomes. OBJECTIVE: To examine the process and cost of hospital-based services for perinatal asphyxia and low birth weight/preterm at a district and a regional level referral hospital in Ghana. METHODS: A cross-sectional study was conducted at 2 hospitals in Greater Accra Region during May-July 2016. Term infants with perinatal asphyxia and low birth weight/preterm infants referred for special care within 24hours after birth were eligible. Time-driven activity-based costing (TDABC) approach was used to examine the process and cost of all activities in the full cycle of care from admission until discharge or death. Costs were analysed from health provider's perspective. RESULTS: Sixty-two newborns (perinatal asphyxia 27, low-birth-weight/preterm 35) were enrolled. Cost of care was proportionately related to length-of-stay. Personnel costs constituted over 95% of direct costs, and all resources including personnel, equipment and supplies were overstretched. CONCLUSION: TDABC analysis revealed gaps in the organization, process and financing of neonatal services that undermined the quality of care for hospitalized newborns. The study provides baseline cost data for future cost-effectiveness studies on neonatal services in Ghana. FUNDING: Authors received no external funding for the study.

Parental costs for in-patient neonatal services for perinatal asphyxia and low birth weight in Ghana.

The major causes of newborn deaths in sub-Saharan Africa are well-known and countries are gradually implementing evidence-based interventions and strategies to reduce these deaths. Facility-based care provides the best outcome for sick and or small babies; however, little is known about the cost and burden of hospital-based neonatal services on parents in West Africa, the sub-region with the highest global neonatal death burden. To estimate the actual costs borne by parents of newborns hospitalised with birth-associated brain injury (perinatal asphyxia) and preterm/low birth weight, this study examined economic costs using micro-costing bottom-up approach in two referral hospitals operating under the nationwide social health insurance scheme in an urban setting in Ghana. We prospectively assessed the process of care and parental economic costs for 25 out of 159 cases of perinatal asphyxia and 33 out of 337 cases of preterm/low birth weight admitted to hospital on the day of birth over a 3 month period. Results showed that medical-related costs accounted for 66.1% (IQR 49% - 81%) of out-of-pocket payments irrespective of health insurance status. On average, families spent 8.1% and 9.1% of their annual income on acute care for preterm/LBW and perinatal asphyxia respectively. The mean out-of-pocket expenditure for preterm/LBW was $147.6 (median $101.8) and for perinatal asphyxia was $132.3 (median $124). The study revealed important gaps in the financing and organization of health service delivery that may impact the quality of care for hospitalised newborns. It also provides information for reviewing complementary health financing options for newborn services and further economic evaluations.

Asphyxia in the Newborn: Evaluating the Accuracy of ICD Coding, Clinical Diagnosis and Reimbursement: Observational Study at a Swiss Tertiary Care Center on Routinely Collected Health Data from 2012-2015.

BACKGROUND: The ICD-10 categories of the diagnosis "perinatal asphyxia" are defined by clinical signs and a 1-minute Apgar score value. However, the modern conception is more complex and considers metabolic values related to the clinical state. A lack of consistency between the former clinical and the latter encoded diagnosis poses questions over the validity of the data. Our aim was to establish a refined classification which is able to distinctly separate cases according to clinical criteria and financial resource consumption. The hypothesis of the study is that outdated ICD-10 definitions result in differences between the encoded diagnosis asphyxia and the medical diagnosis referring to the clinical context. METHODS: Routinely collected health data (encoding and financial data) of the University Hospital of Bern were used. The study population was chosen by selected ICD codes, the encoded and the clinical diagnosis were analyzed and each case was reevaluated. The new method categorizes the diagnoses of perinatal asphyxia into the following groups: mild, moderate and severe asphyxia, metabolic acidosis and normal clinical findings. The differences of total costs per case were determined by using one-way analysis of variance. RESULTS: The study population included 622 cases (P20 "intrauterine hypoxia" 399, P21 "birth asphyxia" 233). By applying the new method, the diagnosis asphyxia could be ruled out with a high probability in 47% of cases and the variance of case related costs (one-way ANOVA: F (5, 616) = 55.84, p < 0.001, multiple R-squared = 0.312, p < 0.001) could be best explained. The classification of the severity of asphyxia could clearly be linked to the complexity of cases. CONCLUSION: The refined coding method provides clearly defined diagnoses groups and has the strongest effect on the distribution of costs. It improves the diagnosis accuracy of perinatal asphyxia concerning clinical practice, research and reimbursement.

Cost analysis of large-scale implementation of the 'Helping Babies Breathe' newborn resuscitation-training program in Tanzania.

BACKGROUND: Helping Babies Breathe (HBB) has become the gold standard globally for training birth-attendants in neonatal resuscitation in low-resource settings in efforts to reduce early newborn asphyxia and mortality. The purpose of this study was to do a first-ever activity-based cost-analysis of at-scale HBB program implementation and initial follow-up in a large region of Tanzania and evaluate costs of national scale-up as one component of a multi-method external evaluation of the implementation of HBB at scale in Tanzania. METHODS: We used activity-based costing to examine budget expense data during the two-month implementation and follow-up of HBB in one of the target regions. Activity-cost centers included administrative, initial training (including resuscitation equipment), and follow-up training expenses. Sensitivity analysis was utilized to project cost scenarios incurred to achieve countrywide expansion of the program across all mainland regions of Tanzania and to model costs of program maintenance over one and five years following initiation. RESULTS: Total costs for the Mbeya Region were $202,240, with the highest proportion due to initial training and equipment (45.2%), followed by central program administration (37.2%), and follow-up visits (17.6%). Within Mbeya, 49 training sessions were undertaken, involving the training of 1,341 health providers from 336 health facilities in eight districts. To similarly expand the HBB program across the 25 regions of mainland Tanzania, the total economic cost is projected to be around $4,000,000 (around $600 per facility). Following sensitivity analyses, the estimated total for all Tanzania initial rollout lies between $2,934,793 to $4,309,595. In order to maintain the program nationally under the current model, it is estimated it would cost $2,019,115 for a further one year and $5,640,794 for a further five years of ongoing program support. CONCLUSION: HBB implementation is a relatively low-cost intervention with potential for high impact on perinatal mortality in resource-poor settings. It is shown here that nationwide expansion of this program across the range of health provision levels and regions of Tanzania would be feasible. This study provides policymakers and investors with the relevant cost-estimation for national rollout of this potentially neonatal life-saving intervention.

A quantitative analysis of optimal treatment capacity for perinatal asphyxia.

OBJECTIVE: In centers electing to offer therapeutic hypothermia for treating hypoxic-ischemic encephalopathy (HIE), determining the optimal number of cooling devices is not straightforward. The authors used computer-based modeling to determine the level of service as a function of local HIE caseload and number of cooling devices available. METHODS: The authors used discrete event simulation to create a model that varied the number of HIE cases and number of cooling devices available. Outcomes of interest were percentage of HIE-affected infants not cooled, number of infants not cooled, and percentage of time that all cooling devices were in use. RESULTS: With 1 cooling device, even the smallest perinatal center did not achieve a cooling rate of 99% of eligible infants. In contrast, 2 devices ensured 99% service in centers treating as many as 20 infants annually. In centers averaging no more than 1 HIE infant monthly, the addition of a third cooling device did not result in a substantial reduction in the number of infants who would not be cooled. CONCLUSION: Centers electing to offer therapeutic hypothermia with only a single cooling device are at significant risk of being unable to provide treatment to eligible infants, whereas 2 devices appear to suffice for most institutions treating as many as 20 annual HIE cases. Three devices would rarely be needed given current caseloads seen at individual institutions. The quantitative nature of this analysis allows decision makers to determine the number of devices necessary to ensure adequate availability of therapeutic hypothermia given the HIE caseload of a particular institution.

Pilot randomized trial of therapeutic hypothermia with serial cranial ultrasound and 18-22 month follow-up for neonatal encephalopathy in a low resource hospital setting in Uganda: study protocol.

BACKGROUND: There is now convincing evidence that in industrialized countries therapeutic hypothermia for perinatal asphyxial encephalopathy increases survival with normal neurological function. However, the greatest burden of perinatal asphyxia falls in low and mid-resource settings where it is unclear whether therapeutic hypothermia is safe and effective. AIMS: Under the UCL Uganda Women's Health Initiative, a pilot randomized controlled trial in infants with perinatal asphyxia was set up in the special care baby unit in Mulago Hospital, a large public hospital with ~20,000 births in Kampala, Uganda to determine:(i) The feasibility of achieving consent, neurological assessment, randomization and whole body cooling to a core temperature 33-34°C using water bottles(ii) The temperature profile of encephalopathic infants with standard care(iii) The pattern, severity and evolution of brain tissue injury as seen on cranial ultrasound and relation with outcome(iv) The feasibility of neurodevelopmental follow-up at 18-22 months of age METHODS/DESIGN: Ethical approval was obtained from Makerere University and Mulago Hospital. All infants were in-born. Parental consent for entry into the trial was obtained. Thirty-six infants were randomized either to standard care plus cooling (target rectal temperature of 33-34°C for 72 hrs, started within 3 h of birth) or standard care alone. All other aspects of management were the same. Cooling was performed using water bottles filled with tepid tap water (25°C). Rectal, axillary, ambient and surface water bottle temperatures were monitored continuously for the first 80 h. Encephalopathy scoring was performed on days 1-4, a structured, scorable neurological examination and head circumference were performed on days 7 and 17. Cranial ultrasound was performed on days 1, 3 and 7 and scored. Griffiths developmental quotient, head circumference, neurological examination and assessment of gross motor function were obtained at 18-22 months. DISCUSSION: We will highlight differences in neonatal care and infrastructure that need to be taken into account when considering a large safety and efficacy RCT of therapeutic hypothermia in low and mid resource settings in the future. TRIAL REGISTRATION: Current controlled trials ISRCTN92213707.

Long-term impact of poor birth condition on social and economic outcomes in early adulthood.

OBJECTIVE: The goal of this study was to investigate the association of poor birth condition with long-term social and economic outcomes at 25 to 31 years of age. METHODS: This was a population-based cohort study using data derived from linkage of routinely collected Swedish data. All term infants born in Sweden between 1973 and 1979 identified from the Swedish birth registry (n = 651 615) were included in the study. Infants were categorized into 3 groups: (1) infants with a normal (>7) Apgar score at 1 or 5 minutes of age without encephalopathy; (2) infants with a low (<7) Apgar score at 1 and 5 minutes of age without encephalopathy; and (3) infants with a low (<7) Apgar score at 1 and 5 minutes with evidence of encephalopathy. The main outcome measures were achievement of a university education and participant's income in early adulthood. RESULTS: Infants with low Apgar scores who did not develop encephalopathy were less likely to have attended university (odds ratio [OR]: 1.14 [95% confidence interval (CI): 1.05-1.23]) and were more likely to have no income from work (OR: 1.19 [95% CI: 1.07-1.32]) than those born in good condition. Infants who developed encephalopathy also had greater risks of these adverse outcomes (not attended university, OR: 1.94 [95% CI: 1.13-3.33]); no income from work, OR: 3.08 [95% CI: 1.89-5.01]). CONCLUSIONS: Infants born in poor condition had worse measures of social performance than their peers, and this association was not restricted to those infants who developed obvious neurologic symptoms in the neonatal period. However, even in infants with likely encephalopathy, more than half obtained employment and one third attended university.

[Cesarean section on demand--an equivalent alternative to spontaneous delivery?]. / Die Wunschsectio--Eine gleichwertige Alternative zur Spontangeburt?

Due to advances in perioperative management, surgical techniques as well as anaesthesia, caesarean section has become a very safe intervention for mother and child. In certain high-risk situations, an early delivery by caesarean section can prevent serous morbidity and mortality of the fetus and newborn. It has been postulated that a planned caesarean section is a true alternative to vaginal birth, and in the absence of a specific medical reason the woman's demand may be an indication for the operation. A critical review of studies based on large regional perinatal datasets shows that the risk for minor as well as serious complications in the mother and the newborn is increased after planned caesarean section. Serious consequences for subsequent pregnancies like uterine rupture or placenta praevia, which may be associated with accreta or abruptio of the placenta, are of major concern. On the other hand, trauma to the pelvic floor with urinary or anal incontinence is more frequent after vaginal birth. The balance of these risks including the very rare cases of severe intrapartal asphyxia, which might be prevented by a planned caesarean section, must be carefully evaluated together with the patient on an individual basis. These risks must be carefully balanced and the final decision about the type of delivery requires a detailed informed consent.critical review of studies based on large regional perinatal datasets shows that the risk for minor as well as serious complications in the mother and the newborn is increased after planned caesarean section.
