Abstract
Objectives
To identify reasons for neonatal admission and death with the aim of determining areas needing improvement.
Method
A retrospective chart review was conducted on records for neonates admitted to Mulago National Referral Hospital Special Care Baby Unit (SCBU) from 1st November 2013 to 31st January 2014. Final diagnosis was generated after analyzing sequence of clinical course by 2 paediatricians.
Results
A total of 1192 neonates were admitted. Majority 83.3% were in-born. Main reasons for admissions were prematurity (37.7%) and low APGAR (27.9%).Overall mortality was 22.1% (Out-born 33.6%; in born 19.8%). Half (52%) of these deaths occurred in the first 24 hours of admission. Major contributors to mortality were prematurity with hypothermia and respiratory distress (33.7%) followed by birth asphyxia with HIE grade III (24.6%) and presumed sepsis (8.7%). Majority of stable at risk neonates 318/330 (i.e. low APGAR or prematurity without comorbidity) survived. Factors independently associated with death included gestational age <30 weeks (p 0.002), birth weight <1500g (p 0.007) and a 5 minute APGAR score of < 7 (p 0.001). Neither place of birth nor delayed and after hour admissions were independently associated with mortality.
Conclusion and recommendations
Mortality rate in SCBU is high. Prematurity and its complications were major contributors to mortality. The management of hypothermia and respiratory distress needs scaling up. A step down unit for monitoring stable at risk neonates is needed in order to decongest SCBU.

Background
Globally an estimated 6.3 million children under 5 years die annually with 44% of these deaths occurring during the first month of life1,2. Ninety eight percent of the global neonatal deaths occur in developing countries2,3. Sub-Saharan Africa accounts for 39.3% of all these deaths2. Whereas most developing countries have made strides towards reducing under five mortality, further reduction has become challenging and the slow decline in neonatal mortality rate has been identified as the major obstacle to further reduction of under-five mortality2,4,5. Many community based interventions designed to address neonatal mortality in developing countries may have contributed to some decline in neonatal deaths6 but further reduction in neonatal deaths in the developing countries will need scaling up care in health facilities.
In Uganda, neonatal mortality contributes 26% of under-five mortality. Like most developing countries; decline in neonatal mortality rate in Uganda at 2.2% per annum has not been significant7. With intensive effort in addressing maternal and neonatal mortality in the community6,8 there has been an increase in health facility deliveries (57%) but the total number of neonates dying annually has reduced decimally7,9. Previously, global data was used by local policy makers in Uganda to develop newborn survival priorities, local data is very crucial but still very scanty7.
The Special Care baby Unit (SCBU) of Mulago National Referral Hospital is the busiest neonatal Unit in Uganda and largest training unit for doctors and other health workers with respect to neonatal care. Being the busiest neonatal unit it can be used as a model for the other referral units in Uganda. The last study conducted in SCBU to describe outcome of babies was in 1989 when the admission rate was about 133 neonates per month and it revealed neonatal mortality of 18.0%10. Currently the SCBU admits 400 neonates per month yet with respect to space, equipment's and staffing there has been no change. Being a major referral unit, understanding current trend in admission and outcome in SCBU is important in identifying areas that need improvement but equally important in planning facility based newborn care service in Uganda at large.
Method
Study setting and population
Mulago National Referral Hospital is situated in Kampala (the capital city of Uganda) serving the urban and peri-urban communities. It is a teaching institution for Makerere University College of Health Sciences and other health training schools. The hospital has over 33,000 births annually.
The Mulago SCBU receives in-born and out-born babies. At full capacity, the unit has 49 cots/incubators plus 6 adult beds for rooming-in (Kangaroo care) but admits sometimes up to thrice its capacity with neonates sharing incubators. Approximately 400 sick babies are admitted every month.
The unit is staffed with 3 paediatricians and 16 nurses. The nurses work in 8 hour shifts and on average each shift has 3 nurses. The unit also has 2 intern doctors and 2–4 paediatric resident doctors on rotational basis. At night the unit is covered by 2 nurses and 1 intern doctor. The unit has 3 sections (a preterm, term and Kangaroo section) each measuring about 10×6 meters. The preterm section has 19 incubators and 2 radiant warmers while term section has 20 baby cots and 3 incubators. There is hardly space between incubators and cots. There is no demarcated area for critically ill babies.
The unit functions at level II but receives critically ill neonates in need of advanced respiratory and cardiovascular support. Services offered in the unit include provision of intravenous antibiotics, intravenous fluids mainly as boluses, phototherapy and nasal tube feeding. Maximum respiratory support available is with fixed expiratory valve Continuous Positive Airway Pressure (CPAP) using fisher and pykel setup without heating or blending oxygen and Hudson's nasal prong. Mothers/caregivers feed their babies on a two hourly basis.
Continuous vital monitoring is not readily available. Servo-control temperature regulation for babies is out of reach. CPAP is provided using cold non blended oxygen. Initiation and discontinuation of phototherapy is entirely on clinical grounds. Laboratory guidance of care is seldom used as specimen containers are not readily available, laboratory cannot run all tests and results not given promptly.
Study design, sample selection and data collection
A retrospective descriptive study was conducted including all neonates admitted to the SCBU of Mulago Hospital in the months of November 2012 to January 2013. All files for neonates admitted during the study period were retrieved from records. All relevant data were captured and missing data noted.
A list of diagnoses / problems was generated (low APGAR score, prematurity, Prematurity + hypothermia, Prematurity + Hypothermia + Respiratory Distress Syndrome (RDS), Prematurity + RDS, Asphyxia + Hypoxic ischemic Encephalopathy (HIE) I, Asphyxia + HIE II, Asphyxia + HIE III, presumed sepsis, Transient Tachypnea of the newborn (TTN), Jaundice, Fever + Dehydration, Hemorrhagic disease of the newborn (HDN), birth defect, birth injury, Meconium aspiration syndrome (MAS), Others). Although some babies might have had more than one problem the most important was considered. For any contradiction in terms of diagnosis two Paediatricians analyzed the sequence of events and determine the most likely final diagnosis.
Term neonates delivered by Caesarean section with respiratory distress that settled within 24 hours were categorized as having TTN. Preterm neonates with distress needing CPAP were categorized as RDS. Term neonates with low 5 minute APGAR Score or stated as low APGAR Score but non-quantified who were encephalopathic (abnormal posture, unconscious, abnormal tone or seizures) were given a diagnosis of asphyxia. Hypoxic ischemic Encephalopathy (HIE) was graded according to the Sarnat grading11. Term neonates admitted with non-quantified APGAR score but documented as ‘low’ and who were not encephalopathic were considered as admitted for “low APGAR Score”.
Neonates admitted one hour after birth who had indication for admission (APGAR score <7 at 5minutes and Very Low Birth Weight) were labeled as delayed admission. Neonates admitted >12 hrs of age who had no initial indication for admission were labeled as >12 hrs but not delayed. All babies weighing less than 2000g had estimated gestational age through New Ballard score12.
Admission temperature of <36.0°C was hypothermia. Babies delivered to mothers with offensive liquor, prolonged rupture of membranes >24 hrs, or maternal chorioamnionitis and those febrile with a temperature >38.0°C while not dehydrated were given a diagnosis of presumed sepsis. Babies who were admitted between 5:00 pm and 8:00 am were termed ‘after-hours admissions’ and those admitted between 8am and 5pm were termed ‘in-hours’ admissions.
Data analysis
Relevant data of the study population were entered into STATA and imported to SPSS 12.0.1 for analysis. The analysis of patient demographics and baseline outcome variables were summarized using descriptive summary measures: expressed as mean (standard deviation) or median (range) for continuous variables and percent for categorical variables.
All statistical tests were performed using two-sided tests at the 0.05 level of significance. For the regression model, the results were expressed as effect (or odds ratios for binary outcomes), corresponding two-sided 95% confidence intervals and associated p values. The p-values were reported to three decimal places with values less than 0.001 reported as <0.001.
Permission was obtained from the hospital management and the institutional ethics review committee to utilize the neonatal records for this study.

Discussion
The overall mortality of 22.1% observed in the Mulago SCBU during the three months was higher than that observed in the same unit in the early 90's10 and higher than that observed in the other developing countries13–15. This can be attributed to the high number of babies admitted to the Mulago SCBU unit with inadequate services and personnel.
Whereas initiatives to reduce neonatal mortality in the community are being implemented, a concurrent scaling up of care in the health facilities where referrals of difficult cases are envisaged is not taking place. Improvement in public health systems has been highlighted as a necessary component to achieving reduction in neonatal and under 5 mortality16–18.
Majority of deaths (52%) occurred within the first 24 hours, this finding is similar to that observed in neonatal units in other developing countries3,14,15. Out born babies had higher mortality 33.6% compared to inborn 19.8%, this trend is also similar to that observed in other settings14,15,20 but place of birth was not independently associated with mortality. This finding only suggest that place of birth is not the problem but the immediate care babies receive needs to be improved.
Whereas facility newborn care is viewed as necessary in reducing neonatal deaths, factors that have been identified in enabling this to occur included regionalization of perinatal care, strengthening of lower level units, in-born status and adequate nursing staff19. The admission rates to SCBU has almost tripled yet the staffing and facilities have remained same. For SCBU to realize reduction in neonatal mortality there is need for more staffing, space and equipment. It is also clear that out-born neonates had higher mortality whether delivered at home or in health facility. This observation calls for strengthening of lower level centers
The main contributors to mortality were prematurity with hypothermia and RDS 33.7%, asphyxia with HIE grade III 24.6%, presumed sepsis 8.7%, prematurity with RDS 8.3% and prematurity with hypothermia 7.6%. This finding is not in keeping with patterns observed in the unit in early 80's10 and that observed in health facilities in the other developing countries where asphyxia is the main contributor to mortality13–15. This observation can be explained by the fact that Mulago SCBU being a tertiary centre has a high preterm birth burden; 449 (37.7%) of the babies admitted during the study period were preterm and the unit is not well facilitated to handle these numbers.
From the analysis low APGAR score non-quantified without associated encephalopathy was the main indication for admission of babies in to the SCBU (15%). Although this did not contribute significantly to mortality (OR 0.16); APGAR score <7 at 5 minutes was independently associated with mortality with an Odds of 2.23 and p > 0.001 in the multivariate analysis. Whereas it is a good practice to admit babies who score poorly at birth21 since low APGAR score of less than 7 at 5minutes has been shown to be associated with asphyxia, poor neuro-developmental outcome and even death22; more objective admission criteria like APGAR score less than 7 at 5 minutes would reduce unnecessary admissions into the Mulago SCBU.
The other main indication for admission of babies into the SCBU was prematurity (12.6%) without any other co-morbidity. Admission with diagnosis of prematurity alone was protective against death OR (0.247 p>0.00). Birth weight of <1500g was a better predictor of mortality than maturity, and odds of death increased with reducing birth weight. This is in keeping with findings from the other centers14,15,20. Admitting babies based on birth weight rather than maturity status using 1500g and below as an admission criteria would reduce number of babies admitted to the unit.
Although using birth weight of ≤1500g and APGAR Score of <7 at 5 minutes as an admission criteria would reduce admissions to SCBU, a step down level where at risk babies are admitted for close monitoring is essential to ensure that these babies are safely discharged home. This calls for more space, personnel, monitoring equipment and guidelines for discharge or escalation of care. The third leading indication for admission was prematurity and hypothermia (11.5%), this was not associated with mortality (OR 0.568), whereas it is well known that hypothermia is an independent predictor of death, from this data it wasn't the case. This again calls for functional step down level where Kangaroo mother care (KMC) can be instituted promptly with early initiation of breast feeding to prevent hypothermia and SCBU admission among low birth weight stable babies. KMC on low birth weight babies has been associated with reduced morbidity and mortality23.
Respiratory distress was the other major indication for admission, TTN 9.7% and RDS of prematurity 13.6%. RDS of prematurity was significantly associated with death. Prematurity with RDS was associated with death (OR 8.66, p 0.03) while the association between Prematurity with RDS and hypothermia with death was even higher (OR 33, p <0.00). From this data it is evident that preventing hypothermia should reduce mortality among preterm neonates with RDS. The European guideline on management of RDS in preterm neonates evokes the need for good thermal regulation as necessity in improving outcome of preterm neonates with RDS24. The use of plastic bags at birth and during transportation of preterm babies need be advocated for25. More heat sources including radiant warmers and incubators need to be put in place in order to stop the practice of sharing heat source and to encourage servo control thermoregulation for preterm neonates. It is also necessary that oxygen given is heated up as this can be a cause for hypothermia. For these to be instituted more space and personnel are necessary.
Out of 46 babies admitted with prematurity and RDS without hypothermia, 22 (47.8%) died despite receiving CPAP since this was the only intervention available for RDS. It is imperative that SCBU scales up care with respect to RDS care. Advocacy for antenatal steroid and designing protocol on care for RDS including when surfactant should be given is critical. Surfactant is an expensive medicine, it is important for us to appreciate that more than 50% of these babies survived with just CPAP, so clear criteria on who to give surfactant is vital for the unit not to throw away expensive resource and at the same time reduce mortality. There is mounting evidence that early CPAP reduces need for surfactant, mechanical ventilation and broncho pulmonary dysplasia26. Provision of fully functional CPAP with capacity to heat and humidify air and using oxygen blenders should help the unit identify babies who qualify for surfactant and those who fail CPAP therapy needing more advanced respiratory support.
Birth asphyxia with grade III HIE was significantly associated with death OR 77.8, p<0.00. It is well known grade III HIE is significantly associated with mortality and morbidity even in highly sophisticated settings27. Eight neonates with grade III HIE and 40 with grade II HIE survived but the quality of their life is questionable. These 48 neonates would be categorized as missed opportunity. To improve quality of life of HIE survivors it is necessary that the SCBU develops capacity to provide standard therapeutic hypothermia for these babies28. Research is also needed in the field of asphyxia in low resource setting in order to identify cheaper modalities of care.
Presumed sepsis was another major contributor to mortality among neonates admitted to the SCBU, out of 64 babies admitted with diagnosis of presumed sepsis, 23 died. Currently SCBU babies are managed clinically for sepsis. No standard work up is done; choice of antibiotic is based on old studies and text book literature. New study to ascertain pathogens and sensitivity pattern is necessary if deaths from sepsis are to be reduced in the unit.
Conclusion
Mortality rate in SCBU is high. Prematurity and its complications were major contributors to mortality. The management of hypothermia and respiratory distress needs scaling up. In order to decongest SCBU a revision of admission criteria and a step down unit for monitoring stable at risk neonates is needed.
Study limitations
This was a retrospective chart review. Some relevant information might have not been captured. Most diagnoses were made on clinical grounds, no investigations were done. Direct cause of death could not be ascertained since investigations were not carried out, and postmortems not done.
What is already known? Major causes of death in low resource settings are asphyxia, prematurity and infection What this study adds: Admission and mortality rates are increasing. It is clear from this study that prematurity with other co-morbidities are the major contributors of death. It is also clear that a good proportion of babies with asphyxia survive.
