Abstract
INTRODUCTION Mothers' participation in the care of their sick newborns in Newborn Care Units (NCUs) has been linked to several advantages including earlier discharge, fewer complications, better mother-baby bonding, and an easier transition to home after discharge. This study aimed to understand mothers' perceptions and experiences while participating in the care of their sick newborns in the NCUs to inform interventions promoting mothers' participation in public health facilities in Uganda. METHODS We conducted an exploratory qualitative study comprised of 18 in-depth interviews with mothers caring for their newborns in two NCUs at a Regional Referral and General hospital in Eastern Uganda between April and May 2022. The interviews were audio-recorded and then transcribed. For analysis, we used a thematic analysis approach. RESULTS The fear of losing their baby was an overarching theme that underlay mothers' perceptions, actions, and experiences in the NCU. Mothers' confidence in the care provided to their babies was based on their baby's outcomes. For example, when mothers saw almost immediate improvement after treatment, they felt more confident in the care than when this was not the case. Furthermore, mothers considered it essential that health care providers responded quickly in an emergency. Moreover, they expressed concerns about a lack of control over their personal space in the crowded NCU. Additionally, caring for babies in these settings is physically and financially taxing, with mothers requiring the combined efforts of family members to help them cope. CONCLUSION This study shows that for mothers of sick newborns in the NCU, the baby's survival is the first concern and the basis of mothers' confidence in the quality of care provided. Efforts to improve parental participation in NCUs must focus on lowering the costs incurred by families in caring for a baby in the NCU, addressing privacy and space concerns, leveraging the family's role, and avoiding compromising the quality of care in the process of participation.

Perceptions, beliefs, and current practices regarding neonatal skin care and emollient use in eastern Uganda: a qualitative study. BMC Pediatr 2023; 23:223. [PMID: 37147698 PMCID: PMC10163695 DOI: 10.1186/s12887-023-04040-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 04/27/2023] [Indexed: 05/07/2023] Open
Abstract
BACKGROUND The skin is a major route of infection in the neonatal period, especially in low birthweight (LBW) infants. Appropriate and safe neonatal skin care practices are required to reduce this risk. The perceptions and beliefs of mothers and other caregivers towards various neonatal skin care practices in our setting have been documented. Data from Asia suggests that the application of emollient to the skin of LBW infants can promote growth, reduce serious neonatal infections, and potentially reduce mortality. This is the first study to explore the acceptability of emollients and massage as part of neonatal skin care in a low-resource setting in sub-Saharan Africa (SSA) that is representative of the majority of government health facilities in Uganda and many in SSA. OBJECTIVE To explore perceptions, beliefs, and current practices regarding neonatal skin care and emollient use in eastern Uganda. METHODS We conducted a qualitative study consisting of three focus group discussions (30 participants), eight in-depth interviews with mothers/caregivers of preterm and term neonates and 12 key informant interviews with midwives, doctors and community health workers involved in neonatal care, to explore the perceptions and practices surrounding neonatal skin care and emollient use. Data collected were transcribed and analyzed using thematic content analysis. RESULTS Mothers perceived that skin care began in utero. Skincare practices depended on the place of delivery; for deliveries in a health facility the skincare practices were mainly based on the health worker's advice. Vernix caseosa was often washed off due to its perceived undesirability and was attributed to sexual intercourse in the last trimester. Despite their deleterious attributes found in previous studies, petrolatum-based oils, petrolatum-based jellies and talcum baby powders were the most commonly reported items used in neonatal skin care. In our population, there was high acceptability of emollient therapy use; however, neonatal massage was treated with scepticism as mothers feared damaging the vulnerable neonate. Mothers suggested massage and emollient application be undertaken by health workers, if it becomes an intervention. CONCLUSIONS In eastern Uganda, the perceptions and beliefs of mothers/caregivers toward neonatal skincare influenced their practices of which some could potentially be beneficial, and others harmful. Emollient use would be easily accepted if adequate sensitisation is conducted and using the gatekeepers such as health workers.

‘They said, let’s teach you how you are going to care for the child at home…’: caregivers’ and healthcare worker’s perceptions and experiences of post-discharge preterm care in eastern Uganda. BMC Health Serv Res 2022; 22:1521. [PMCID: PMC9749343 DOI: 10.1186/s12913-022-08894-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 11/28/2022] [Indexed: 12/15/2022] Open
Abstract
Abstract
Background
Complications of prematurity are the leading cause of neonatal mortality, and the majority of these deaths occur in low and middle-income countries. Research in these settings has focused on improved outcomes for preterm infants in hospital settings, however, research into the continuation of preterm care in the home after discharge from a neonatal unit is limited. This study examines the experiences and perceptions of caregivers of preterm infants during the initial weeks following discharge from a neonatal unit in Uganda, and the views of healthcare workers (HCWs) on the ability of caregivers to cope.
Methods
This qualitative study used multiple data collection approaches, namely focus group discussions (FGDs), in-depth interviews (IDIs), field observations, and case studies to explore the perceptions and experiences of providing care to preterm infants post-discharge from a neonatal unit in eastern Uganda from the perspectives of caregivers and HCWs.
Results
We recruited 39 participants with a total of 35 separate sessions including 18 IDIs (12 caregivers and 6 HCWs), 3 FGDs (17 caregivers), and 4 case studies (14 separate IDIs over 5 weeks after discharge, three mothers, and one grandmother). IDIs and FGDs took place at the Mbale Regional Referral Hospital or in participants’ homes.
Key themes emerged; preparation for continuing care in the home, psychosocial challenges to providing preterm care in the home, barriers to continuing preterm care in the home, and suggestions for improvement of preterm care in the home. Caregivers had good knowledge and awareness about different aspects of preterm care. Following discharge, caregivers struggled to maintain quality care due to loss of continuous support from the neonatal team, feelings of anxiety and isolation, financial issues, and home responsibilities.
Conclusion
This study highlights multiple challenges to continuing preterm care in this Ugandan setting. Improved training and education for caregivers, especially in neonatal resuscitation, enhanced and continued support of the caregiver and infant in the home, and increased community involvement following discharge may all be key solutions. These findings are fundamental to improving care in the home for preterm infants in eastern Uganda and similar settings.

Abstract
OBJECTIVE To assess the impact of secondary and tertiary level neonatal interventions on neonatal mortality over a period of 11 years. DESIGN Interrupted time series analysis. SETTING Nsambya Hospital, Uganda. INTERVENTIONS Neonatal secondary interventions (phase I, 2007-2014) and tertiary level interventions (phase II, 2015-2020). PARTICIPANTS Neonates. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome: neonatal mortality. SECONDARY OUTCOME case fatality rate (CFR) for prematurity, neonatal sepsis and asphyxia. RESULTS During the study period, a total of 25 316 neonates were admitted, of which 1853 (7.3%) died. The average inpatient mortality reduced from 8.2% during phase I to 5.7% during phase II (p=0.001). The CFR for prematurity reduced from 16.2% to 9.2% (p=0.001). There was a trend in reduction for the CFR of perinatal asphyxia from 14.9% to 13.0% (p=0.34). The CFR for sepsis had a more than a twofold increase (3%-6.8% p=0.001) between phase I and phase II. CONCLUSION Implementation of secondary and tertiary neonatal care in resource-limited settings is feasible. This study shows that these interventions can significantly reduce the neonatal mortality, with the largest impact seen in the reduction of deaths from perinatal asphyxia and prematurity. An increase in sepsis related deaths was observed, suggesting emphasis on infection control is key.

Abstract
OBJECTIVE The aim of this study was to identify knowledge translation (KT) strategies aimed at improving sexual, reproductive, maternal, newborn, child and adolescent health (SRMNCAH) and well-being. DESIGN Rapid scoping review. SEARCH STRATEGY A comprehensive and peer-reviewed search strategy was developed and applied to four electronic databases: MEDLINE ALL, Embase, CINAHL and Web of Science. Additional searches of grey literature were conducted to identify KT strategies aimed at supporting SRMNCAH. KT strategies and policies published in English from January 2000 to May 2020 onwards were eligible for inclusion. RESULTS Only 4% of included 90 studies were conducted in low-income countries with the majority (52%) conducted in high-income countries. Studies primarily focused on maternal newborn or child health and well-being. Education (81%), including staff workshops and education modules, was the most commonly identified intervention component from the KT interventions. Low-income and middle-income countries were more likely to include civil society organisations, government and policymakers as stakeholders compared with high-income countries. Reported barriers to KT strategies included limited resources and time constraints, while enablers included stakeholder involvement throughout the KT process. CONCLUSION We identified a number of gaps among KT strategies for SRMNCAH policy and action, including limited focus on adolescent, sexual and reproductive health and rights and SRMNCAH financing strategies. There is a need to support stakeholder engagement in KT interventions across the continuum of SRMNCAH services. Researchers and policymakers should consider enhancing efforts to work with multisectoral stakeholders to implement future KT strategies and policies to address SRMNCAH priorities. REGISTRATION The rapid scoping review protocol was registered on Open Science Framework on 16 June 2020 (https://osf.io/xpf2k).

Abstract
Facility-based births have increased in low and middle-income countries, but babies still die due to poor care. Improving care leads to better newborn outcomes. However, data are lacking on how well facilities are prepared to support. We assessed the availability of human and material resources and barriers to delivering quality care for newborns and barriers to delivering quality care for newborns. We adapted the WHO Service Availability and Readiness Assessment tool to evaluate the resources for delivery and newborn care and barriers to delivering care, in a survey of seven hospitals in southern Malawi between January and February 2020. Data entered into a Microsoft Access database was exported to IBM SPSS 26 and Microsoft Excel for analysis. All hospitals had nursery wards with at least one staff available 24 hours, a clinical officer trained in paediatrics, at least one ambulance, intravenous cannulae, foetal scopes, weighing scales, aminophylline tablets and some basic laboratory tests. However, resources lacking some or all of the time included anticonvulsants, antibiotics, vitamin K, 50% dextrose, oxytocin, basic supplies such as cord clamps and nasal gastric tubes, laboratory tests such as bilirubin and blood culture and newborn clinical management guidelines. Staff reported that the main barriers to providing high-quality care were erratic supplies of power and water, inadequacies in the number of beds/cots, ambulances, drugs and supplies, essential laboratory tests, absence of newborn clinical protocols, and inadequate staff, including paediatric specialists, in-service training, and support from the management team. In hospitals in Malawi, quality care for deliveries and newborns was compromised by inadequacies in many human and material resources. Addressing these deficiencies would be expected to lead to better newborn outcomes.

Abstract
Introduction Globally, neonatal deaths continues to be a challenge especially to to attainment of sustainable development goal 3. About 4 million neonatal deaths per year, with 99% of the deaths occurring in low and middle resource countries, 75% of these occurring in the first week of life. Prematurity remains an indirect leading cause of mortality and morbidity. Uganda's progress on the improvement of perinatal morbidity and mortality has largely stagnated at 27 deaths per 1,000 live births from the year 2006. One of the cost-effective readily available interventions that would curtail perinatal mortality is kangaroo mother care(KMC)- a low tech four decades old intervention. However challenges about its implementation persist on in Uganda despite intensified implementation and roll-out startegies in 2010. This study, the first of its kind to the best of our knowledge in eastern Uganda sought to find the facilitators and barriers of KMC. Materials and methods This was a qualitative study using in-depth interviews(IDI) carried out at a tertiary university teaching hospital. Twenty IDIs were carried out among mothers/caretakers using the phenomena theory. After each IDI, each transcript was analyzed by two researchers working independently using NVIVO software version 11 plus (QSR International, Burlington, Massachusetts) and themes and subthemes developed. Results Majority of mothers/caretakers, were adolescents and young adults and primiparous at 55%. The major facilitators to KMC were supportive staff that facilitated positive attitude, ability to substitute provider and family support.The major barriers were lack of family support, lack of male involvement, maternal stress and poor health and multiple gender roles, infrastructural challenges, and misconceptions associated with preterm births such as early sexual intercourse and lack of herbal medicine use. Conclusion More facility leadership involvement and engagement of mothers during antenatal, community and promotion of male involvement in sexual and reproductive health matters will improve uptake of KMC. This can be spearheadded by sexual and reproductive health, and neonatal and child health care service providers.

Abstract
Large disparities in maternal and neonatal mortality exist between low- and high-income countries. Mothers and babies continue to die at high rates in many countries despite substantial increases in facility birth. One reason for this may be the current design of health systems in most low-income countries where, unlike in high-income countries, a substantial proportion of births occur in primary care facilities that cannot offer definitive care for complications. We argue that the current inequity in care for childbirth is a global double standard that limits progress on maternal and newborn survival. We propose that health systems need to be redesigned to shift all deliveries to hospitals or other advanced care facilities to bring care in line with global best practice. Health system redesign will require investing in high-quality hospitals with excellent midwifery and obstetric care, boosting quality of primary care clinics for antenatal, postnatal, and newborn care, decreasing access and financial barriers, and mobilizing populations to demand high-quality care. Redesign is a structural reform that is contingent on political leadership that envisions a health system designed to deliver high-quality, respectful care to all women giving birth. Getting redesign right will require focused investments, local design and adaptation, and robust evaluation.

Intraventricular haemorrhage in a Ugandan cohort of low birth weight neonates: the IVHU study. BMC Pediatr 2021; 21:12.

Abstract
Background Globally, 15 million neonates are born prematurely every year, over half in low income countries (LICs). Premature and low birth weight neonates have a higher risk of intraventricular haemorrhage (IVH). There are minimal data regarding IVH in sub-Saharan Africa. This study aimed to examine the incidence, severity and timing of and modifiable risk factors for IVH amongst low-birth-weight neonates in Uganda. Methods This is a prospective cohort study of neonates with birthweights of ≤2000 g admitted to a neonatal unit (NU) in a regional referral hospital in eastern Uganda. Maternal data were collected from interviews and medical records. Neonates had cranial ultrasound (cUS) scans on the day of recruitment and days 3, 7 and 28 after birth. Risk factors were tabulated and are presented alongside odds ratios (ORs) and adjusted odds ratios (aORs) for IVH incidence. Outcomes included incidence, timing and severity of IVH and 28-day survival. Results Overall, 120 neonates were recruited. IVH was reported in 34.2% of neonates; 19.2% had low grade (Papile grades 1–2) and 15% had high grade (Papile grades 3–4). Almost all IVH (90.2%) occurred by day 7, including 88.9% of high grade IVH. Of those with known outcomes, 70.4% (81/115) were alive on day 28 and survival was not associated with IVH. We found that vaginal delivery, gestational age (GA) < 32 weeks and resuscitation in the NU increased the odds of IVH. Of the 6 neonates who received 2 doses of antenatal steroids, none had IVH. Conclusion In this resource limited NU in eastern Uganda, more than a third of neonates born weighing ≤2000 g had an IVH and the majority of these occurred by day 7. We found that vaginal birth, earlier gestation and need for resuscitation after admission to the NU increased the risk of IVH. This study had a high rate of SGA neonates and the risk factors and relationship of these factors with IVH in this setting needs further investigation. The role of antenatal steroids in the prevention of IVH in LICs also needs urgent exploration.

BACKGROUND The neonatal period is the most vulnerable time in terms of a child's survival, with mortality during this period accounting for approximately half of the deaths before the age of 5 years. The Neonatal Essential Survival Technology (NEST) project is a program aiming to reduce mortality by improving the quality of neonatal care in sub-Saharan Africa. This study presents the evaluation of the first phase of the NEST intervention program at Saint Camille Hospital Ouagadougou (HOSCO), Burkina Faso, in terms of the reduction in neonatal mortality. METHODS This is a retrospective analysis, based on "pre-intervention" data collected in 2015, and "post-intervention" data collected in 2018, including all infants admitted to the neonatal unit of HOSCO. The intervention period (2016 and 2017) comprised a structured quality improvement process conducted by a multidisciplinary working group that focused on improving infrastructure, equipment, training and use of clinical protocols, team working within the neonatal unit and with other hospital departments, and communication with referring healthcare facilities. Mortality data were compared pre- vs. post-intervention using a logistic regression model. RESULTS The analysis included 1427 infants in the pre-intervention period, and 819 post-intervention. In both time periods, more than 75% of admissions were infants with low birth weight, and nearly 50% were very low birth weight. Post-intervention, while there was a decrease in overall admission, the proportion of multiple births increased from 20% to 24% (p = .01). The overall mortality rate was 44.9% (641/1427) pre-intervention, and 42.2% (346/819) post-intervention (OR 0.90, 95% confidence interval (CI) 0.76-1.07; p = .23). Adjusting for clinically relevant factors, the intervention was not associated with a change in overall mortality (OR 1.39, 95% CI 0.91-2.12; p = .13), but was associated with a reduced likelihood of mortality in outborn infants compared to inborn infants (OR 0.57, 95% CI 0.36-0.92; p = .02). CONCLUSIONS The first phase of the NEST quality improvement program was associated with a decrease in mortality in outborn infants admitted to the neonatal unit at HOSCO. Long-term assessment is expected to provide a more comprehensive evaluation of the program in a low-income setting.

Health workers' views on factors affecting caregiver engagement with bubble CPAP. BMC Pediatr 2020; 20:180.

Abstract
Background Severe respiratory distress is a leading cause of mortality among neonates in Malawi. Despite evidence on the safety, cost effectiveness and efficacy of bubble continuous positive airway pressure (CPAP) in managing the condition, its use in Malawian health facilities is limited and little is known about caregivers’ engagement with perspectives of bubble CPAP. The purpose of this study was to explore caregiver perspectives for bubble CPAP at both central and district hospitals and key factors that enable effective caregiver engagement in Malawi. Methods This was a descriptive qualitative study employing secondary analysis of 46 health care worker in-depth interviews. We interviewed the health workers about their thoughts on caregiver perspectives regarding use of bubble CPAP. We implemented the study at a tertiary facility and three district hospitals in southern Malawi. This was a part of a larger study to understand barriers and facilitators to implementing neonatal innovations in resource-constrained hospitals. Interviews were thematically analysed in NVivo 12 software (QSR International, Melbourne, Australia). Health workers were purposively selected to include nurses, clinicians and district health management involved in the use of bubble CPAP. Results Emerging issues included caregiver fears around bubble CPAP equipment as potentially harmful to their new-borns and how inadequate information provided to caregivers exacerbated knowledge gaps and was associated with refusal of care. However, good communication between health care providers and caregivers was associated with acceptance of care. Caregivers’ decision-making was influenced by relatives and peer advocates were helpful in supporting caregivers and alleviating fears or misconceptions about bubble CPAP. Conclusions Since caregivers turn to relatives and peers for support, there is need to ensure that both relatives and peers are counselled on bubble CPAP for improved understanding and uptake. Health workers need to provide simplified, accurate, up-to-date information on the intervention as per caregivers’ level of understanding. Notably, contextualised comprehensible information will help alleviate caregivers’ fear and anxieties about bubble CPAP.

BMC Pediatr 2019; 19:311. [PMID: 31484567 PMCID: PMC6724283 DOI: 10.1186/s12887-019-1698-x] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Accepted: 08/27/2019] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Complications of prematurity are the leading cause of deaths in children under the age of five. The predominant reason for these preterm deaths is respiratory distress syndrome (RDS). In low-income countries (LICs) there are limited treatment options for RDS. Due to their simplicity and affordability, low-cost bubble continuous positive airway pressure (bCPAP) devices have been introduced in neonatal units in LICs to treat RDS. This study is the first observational study from a LIC to compare outcomes of very-low-birth-weight (VLBW) neonates in pre- and post-CPAP periods. METHODS This was a retrospective study of VLBW neonates (weight < 1500 g) in Mbale Regional Referral Hospital Neonatal Unit (MRRH-NNU), a government hospital in eastern Uganda. It aimed to measure the outcome of VLBW neonates in two distinct study periods: A 14-month period beginning at the opening of MRRH-NNU and covering the period until bCPAP was introduced (pre-bCPAP) and an 18-month period following the introduction of bCPAP (post-bCPAP). After the introduction of bCPAP, it was applied to preterm neonates with RDS when clinically indicated and if a device was available. Clinical features and outcomes of all neonates < 1500 g were compared before and after the introduction of bCPAP. RESULTS The admission records of 377 VLBW neonates < 1500 g were obtained. One hundred fifty-eight were admitted in the pre-bCPAP period and 219 in the post-bCPAP period. The mortality rate in the pre- bCPAP period was 39.2% (62/158) compared with 26.5% (58/219, P = 0.012) in the post-bCPAP period. Overall, there was a 44% reduction in mortality (OR 0.56, 95%CI 0.36-0.86, P = 0.01). There were no differences in birthweight, sex, presence of signs of respiratory distress or apnoea between the two groups. CONCLUSION Specialized and resource-appropriate neonatal care, that appropriately addresses the challenges of healthcare provision in LICs, has the potential to reduce neonatal deaths. The use of a low-cost bCPAP to treat RDS in VLBW neonates resulted in a significant improvement in their survival in a neonatal unit in eastern Uganda. Since RDS is one of the leading causes of neonatal mortality, it is possible that this relatively simple and affordable intervention could have a huge impact on global neonatal mortality.

Abstract
Neonatal tetanus remains a significant, yet avoidable, cause of neonatal death. Despite the 34,000 deaths that occur globally from neonatal tetanus every year, there has been little research into the management of neonatal tetanus. Until worldwide elimination of neonatal tetanus is achieved, the case management of this devastating illness needs to be improved. We describe an improved outcome of neonatal tetanus following the introduction of a neonatal tetanus protocol including diazepam, magnesium sulphate, bubble continuous positive airway pressure and broad-spectrum antibiotics in a low-resource setting in eastern Uganda.

Abstract
Background In 2017, 2.5 million newborns died, mainly from prematurity, infections, and intrapartum events. Preventing these deaths requires health systems to provide routine and emergency care at birth, and quality inpatient care for small and sick newborns. Defined levels of emergency obstetric care (EmOC) and standardised measurement of “signal functions” has improved tracking of maternal care in low- and middle-income countries (LMICs). Levels of newborn care, particularly for small and sick newborns, and associated signal functions are still not consistently defined or tracked. Methods Between November 2016-November 2017, we conducted an online survey of professionals working in maternal and newborn health. We asked respondents to categorise 18 clinical care interventions that could act as potential signal functions for small and sick newborns to 3 levels of care they thought were appropriate for health systems in LMICs to provide: “routine care at birth”, “special care” and “intensive care”. We calculated the percentage of respondents that classified each intervention at each level of care and stratified responses to look at variation by respondent characteristics. Results Six interventions were classified to specific levels by more than 50% of respondents as “routine care at birth,” three interventions as “special care” and one as “intensive care”. Eight interventions were borderline between these care levels. Responses were more consistent for interventions with relevant WHO clinical care guidelines while more variation in respondents’ classification was observed in complex interventions that lack standards or guidelines. Respondents with experience in lower-income settings were more likely to assign a higher level of care for more complex interventions. Conclusions Results were consistent with known challenges of scaling up inpatient care in lower-income settings and underline the importance of comprehensive guidelines and standards for inpatient care. Further work is needed to develop a shortlist of newborn signal functions aligned with emergency obstetric care levels to track universal health coverage for mothers and their newborns.

Abstract
BACKGROUND Worldwide, reduction in under-five mortality has not sufficiently included neonates, who represent 45% of deaths in children of age under five years. The least progress has been observed in resource-limited settings. METHODS This mixed methods study conducted at a Cambodian non-governmental paediatric hospital described the key priorities of the ongoing neonatal service. Routinely collected data from the hospital and microbiology databases included the number of admissions, discharges and deaths and the number of cases of bacteraemias (2011-2016). Semi-structured interviews with the management staff explored the essential features of the service. RESULTS There were 2127 neonatal admissions and 247 deaths. The incidence of facility-based neonatal mortality decreased by 81%. Bacteraemic healthcare-associated infections decreased by 68%. A dedicated area for neonatal care was perceived as crucial, allowing better infection control and delivery of staff training. CONCLUSIONS In this hospital, the neonatal service prioritized basic measures, particularly, having a dedicated neonatal area. Facility-based mortality and bacteraemic healthcare-associated infections decreased.
