Interventions
Routine data collection on neonatal admissions
It was acknowledged that neonatal mortality was high, but as is all too often the case in LICs, accurate data were not available. Routine neonatal data collection was established prior to the implementation of level 1 care and was continued throughout the implementation of the NCP (online supplementary appendix 1). This allowed the burden of neonatal illness and the impact of the quality improvement strategy to be evaluated.
Regular monthly audit of neonatal admissions, outcomes and mortality
Recognising the importance of clinical audit, monthly joint neonatal and maternal mortality meetings were initiated.13 These meetings provided a forum for discussion and allowed ongoing identification of areas for quality improvement and continuing education of the staff.
Maternal education, involvement and empowerment (Mbale mother-centred model)
Traditionally, neonatal care requires a high nurse to patient ratio to provide effective care.14 In many LICs, this is not feasible, and in many instances, it is only a single nurse caring for all the neonates on the ward. In order to replicate one-on-one nursing, the ‘Mbale Mother-Centred Model’ was developed where mothers and attendants were empowered to undertake basic ‘nursing’ care including feeding. A maternal bed was provided adjacent to the neonatal cot to facilitate this. A trained nursing assistant gave daily teaching to the mothers to enable them to monitor axillary temperature and daily weights. The mothers were also taught about the eight danger signs, cord care, the practice and benefits of kangaroo care (KC), how to express breast milk and how to provide spoon-feeding or nasogastric tube feeding.15 Pictorial posters helped reinforce the daily teaching.
Neonates, particularly preterms, are at a high risk of hypothermia even in tropical climates, and it is a leading risk factor for neonatal mortality in LICs.16 17 The absence of continuous power, engineering support, maintenance and satisfactory disinfection makes the safe use of incubators challenging. The NNU room temperature varied from 25°C to 35°C depending on the time of day and season. There was no need therefore to warm the ambient temperature of the room, and thermoregulation was maintained by KC. KC has been proven to half the mortality of preterm infants (<2 kg) through improving thermoregulation, reducing sepsis and improving breastfeeding.18 KC also empowers mothers to care for their preterm at home, a vital tool when mothers cannot afford to spend long in hospital. The NCP focused on training neonatal staff about KC and implementing its use for preterm infants. This practice was continued for neonates on both oxygen and continuous positive airways pressure (CPAP). Mothers were encouraged to practice KC both in the hospital and after discharge.
Protocols and guidelines to aid neonatal case management
Neonatal guidelines were written to provide all staff with a simple framework to assess and manage neonates. When possible, evidence from LICs was used. If unavailable, evidence from middle-income or high-income countries (HICs) was used or adapted, but only when it was affordable, feasible and sustainable. The guidelines were separated into three main sections: emergency care, priority care and ongoing care. The priority care guidelines allowed staff to make a quick assessment of key problems and led them to the correct, immediate and lifesaving management. The ongoing care chapters provided simple but more detailed information on each diagnosis including risk factors, clinical presentation, investigations, emergency management and ongoing management.
Staff training in neonatology
Our 14 module Neonatal Care Training Course complemented the neonatal guidelines. The course was provided free of charge by the paediatrician, and procurement of teaching materials was supported by a non-governmental organisation (NGO). One 2-hour module was taught each week to minimise interference with limited staffing. Acknowledging that neonatal care needed to extend seamlessly into antenatal, perinatal and paediatric care, all staff in the hospital were invited to attend, particularly those working in areas with direct contact with neonates such as maternity and paediatrics. The course began at the inception of level 1 care, and 57 midwives, nurses and interns from MRRH attended. The training included practical sessions, interactive lectures and videos on the recognition and management of common neonatal problems: essential newborn care, neonatal resuscitation, danger signs, routine newborn examination, assessment and immediate management of the sick baby, neonatal infections, babies with difficult breathing, babies with difficult feeding, care of the small baby, care of the jaundice baby, perinatal asphyxia and case scenarios.
Guidelines and training in the administration of neonatal medications
Many medications have no specific preparation for neonates; therefore, the small doses required are often challenging to accurately achieve.19 A simplified formulary based on the British National Formulary for Children was designed for all the neonatal drugs used (figure 2, online supplementary appendix 2).20 A basic prescription chart was introduced to minimise prescription errors (online supplementary appendix 3). For all the staff attending Neonatal Care Training Course, teaching on the formulary, prescription chart, medication preparation and administration was delivered by the hospital pharmacist.

Guidelines and training in the administration of neonatal feeds and intravenous fluids
In LICs, total parenteral nutrition is rarely available, but it is still vital to provide intravenous fluids while neonates establish enteral feeds. Protocols were created for 10% dextrose and neonatal fluid (0.18% saline and 8% dextrose). The protocols also focused on the volume of fluid to be given. Although continuous administration of fluids has key benefits of glucose and blood pressure homeostasis, this can only effectively be achieved by syringe drivers, which are often unavailable in LICs. Other similar settings have used two hourly boluses of intravenous fluid, which is challenging to administer and risks undulating blood pressure and hypoglycaemia.21 The NCP therefore implemented fluid administration using burettes in six hourly volumes. A simple fluid prescription chart was introduced to aid prescription and administration of fluids and feeds (online supplementary appendix 4). Training was given on preparing, calculating and administering intravenous fluids.
Many sick and preterm neonates are unable to breastfeed, so mothers were asked to express breast milk two hourly into a clean dry cup. The cup and other equipment were stored in a clean plastic bucket to prevent contamination, and unused milk was discarded after each feed. Neonates who could suck but not safely swallow, such as preterms >1500 g, were fed using a spoon. Neonates who were unable to swallow safely, such as encephalopathic neonates and preterms <1500 g, used nasogastric tube feeding. All neonates achieved spoon-feeding before discharge.
Dedicated area for neonatal patients and improved infection control policies
During level 1, care neonates were admitted to the paediatric ward, which although common in LICs, was not ideal. Therefore, spatial delineation was made between the 16-bed neonatal area and the paediatric patients. An additional 8-bed side room was allocated for KC and was fitted with a sink for hand washing, a neonatal resuscitation area and an area for fluid and medication preparation. Vital equipment was installed on the paediatric ward; an electronic baby scale (SECA 354), digital axillary thermometers (OMRON Ecotemp Basic), tape measures, a neonatal stethoscope, a neonatal ambu-bag, size 0 and 1 face masks and penguin suction.
Neonatal follow-up clinic
Due to the financial and social constraints that are often faced in LICs, mothers are frequently unable to stay long in hospital. Services are needed to support early discharge and continuation of care as an outpatient. A weekly neonatal follow-up clinic was established to facilitate ongoing care of preterm neonates and neonates who had suffered more severe illnesses such as meningitis or hypoxic ischaemic encephalopathy (HIE). Neonates from both within and from outside the catchment area attended this clinic. Preterm infants were reviewed weekly until 1500 g and fortnightly until 2500 g. Infants were assessed for weight gain, head growth, development and signs of infection. Mothers were given ongoing support in feeding, medications, KC and immunisations, and any unwell neonates were readmitted.
Level 2 care
Dedicated NNU
Neonates, particularly preterms, are at a high risk of contracting infection. In HICs, neonates are admitted to a separate NNU, with strict infection control procedures. To address these key issues and to achieve level 2 care, a dedicated NNU was developed by partitioning off a section of the postnatal ward (figure 3). Multiple electric sockets were installed for equipment, and a power stabiliser was installed to minimise power surges and protect equipment. Sinks were fitted to facilitate hand washing and washing of equipment. A water-tank was installed to ensure a continuous water supply. The development of the NNU infrastructure costs <£2000 and was provided by the hospital administration.

NNU admission criteria were inborn and outborn patients of all gestational ages up to a corrected postnatal age of 28 days. Neonates with skin infections and diarrhoea were not admitted. Lack of space, multiple visitors, overcrowding and lack of running water are but a few factors that make infection control challenging in LICs. Creation of a dedicated NNU addressed some of these issues. Visitors were not permitted, attendants and staff removed their shoes and washed their hands before entering and personal belongings were not allowed. Staff had uniforms that were only worn on the NNU, and a small changing area allowed attendants to change into a hospital gown before entering. A dedicated neonatal assistant cleaned the NNU two times per day. In addition, alcohol sanitiser was provided to cleanse hands and instruments between patients.
Specific beds were allocated to preterms to minimise their contact with infectious cases. A 5-bed high dependency area was located adjacent to the nurse’s station, where the sickest babies were monitored continuously using pulse oximetry (LifeBox). Neonatal bassinets and adjacent maternal beds were provided for each patient to facilitate the practice of KC and the Mbale Mother-Centred Care model.
Investment in appropriate technology for neonatal care
Neonatal care typically relies on a high level of technology such as incubators, ventilators, syringe drivers and CPAP. Such equipment is prohibitively expensive and requires a high-level of healthcare worker training, engineering support, maintenance and a reliable power supply. A number of companies have focused on designing low-cost, robust and simple equipment for low-resource settings. Through stakeholder meetings, key equipment was identified.
Oxygen saturations were monitored (LifeBox) two times per day to promote the responsible use of oxygen.22 23 Three oxygen concentrators (Diamedica) were installed, and flow splitters delivered 0–2.5 L/min to individual infants using nasal cannulae. Three CPAP machines (Diamedica) were used not only for their robust and low-cost nature but also for their ability to blend oxygen and air. This was vital if retinopathy was to be minimised. Phototherapy was provided by LED phototherapy machines (Brilliance) designed for low-resource settings.
Dedicated neonatal staff including a paediatrician and neonatal nurses
The NNU had a dedicated paediatrician and a neonatal clinical officer who led daily ward-rounds. These staff were permanent and did not rotate, they were key to providing continuity and training to the rotating nursing staff. The placement of the neonatal clinical officer was supported by an NGO. In settings like this where doctors are limited, pressure often falls on nursing staff. The NNU had six dedicated nurses and midwives, working 8-hour shifts, allowing one nurse to cover the ward at any time. The neonatal nurses were government nurses/midwives allocated by the hospital administration to work on the NNU.
There is currently no specific neonatal nursing training in Uganda, so the nurses attended the aforementioned local Neonatal Care Training Course and were given on-the-job training by the paediatrician and neonatal clinical officer to help them assess neonates, make simple diagnoses and initiate emergency and immediate management. They were trained in cannulation, venepuncture, capillary blood sampling, nasogastric tube insertion and lumbar punctures. In Uganda, nurses are normally rotated through different wards on an annual basis. During this study, the NNU experienced one rotation of nursing staff at which time two neonatal nurses remained and the new nurses underwent the same training as described above. Key to the success of this project was the presence of permanent staff to provide ongoing mentorship and training.
