Child deaths caused by Klebsiella pneumoniae in sub-Saharan Africa and south Asia: a secondary analysis of Child Health and Mortality Prevention Surveillance (CHAMPS) data.

BACKGROUND: Klebsiella pneumoniae is an important cause of nosocomial and community-acquired pneumonia and sepsis in children, and antibiotic-resistant K pneumoniae is a growing public health threat. We aimed to characterise child mortality associated with this pathogen in seven high-mortality settings. METHODS: We analysed Child Health and Mortality Prevention Surveillance (CHAMPS) data on the causes of deaths in children younger than 5 years and stillbirths in sites located in seven countries across sub-Saharan Africa (Ethiopia, Kenya, Mali, Mozambique, Sierra Leone, and South Africa) and south Asia (Bangladesh) from Dec 9, 2016, to Dec 31, 2021. CHAMPS sites conduct active surveillance for deaths in catchment populations and following reporting of an eligible death or stillbirth seek consent for minimally invasive tissue sampling followed by extensive aetiological testing (microbiological, molecular, and pathological); cases are reviewed by expert panels to assign immediate, intermediate, and underlying causes of death. We reported on susceptibility to antibiotics for which at least 30 isolates had been tested, and excluded data on antibiotics for which susceptibility testing is not recommended for Klebsiella spp due to lack of clinical activity (eg, penicillin and ampicillin). FINDINGS: Among 2352 child deaths with cause of death assigned, 497 (21%, 95% CI 20-23) had K pneumoniae in the causal chain of death; 100 (20%, 17-24) had K pneumoniae as the underlying cause. The frequency of K pneumoniae in the causal chain was highest in children aged 1-11 months (30%, 95% CI 26-34; 144 of 485 deaths) and 12-23 months (28%, 22-34; 63 of 225 deaths); frequency by site ranged from 6% (95% CI 3-11; 11 of 184 deaths) in Bangladesh to 52% (44-61; 71 of 136 deaths) in Ethiopia. K pneumoniae was in the causal chain for 450 (22%, 95% CI 20-24) of 2023 deaths that occurred in health facilities and 47 (14%, 11-19) of 329 deaths in the community. The most common clinical syndromes among deaths with K pneumoniae in the causal chain were sepsis (44%, 95% CI 40-49; 221 of 2352 deaths), sepsis in conjunction with pneumonia (19%, 16-23; 94 of 2352 deaths), and pneumonia (16%, 13-20; 80 of 2352 deaths). Among K pneumoniae isolates tested, 121 (84%) of 144 were resistant to ceftriaxone and 80 (75%) of 106 to gentamicin. INTERPRETATION: K pneumoniae substantially contributed to deaths in the first 2 years of life across multiple high-mortality settings, and resistance to antibiotics used for sepsis treatment was common. Improved strategies are needed to rapidly identify and appropriately treat children who might be infected with this pathogen. These data suggest a potential impact of developing and using effective K pneumoniae vaccines in reducing neonatal, infant, and child deaths globally. FUNDING: Bill & Melinda Gates Foundation.

Prevalence and Missed Cases of Respiratory Distress Syndrome Disease Amongst Neonatal Deaths Enrolled in the Kenya Child Health and Mortality Prevention Surveillance Network (CHAMPS) Program Between 2017 and 2021.

Objectives. To describe RDS in neonatal deaths at the CHAMPS-Kenya site between 2017 and 2021. Methods. We included 165 neonatal deaths whose their Causes of death (COD) were determined by a panel of experts using data from post-mortem conducted through minimally invasive tissue specimen testing, clinical records, and verbal autopsy. Results. Twenty-six percent (43/165) of neonatal deaths were attributable to RDS. Most cases occurred in low birthweight and preterm neonates. From these cases, less than half of the hospitalizations were diagnosed with RDS before death, and essential diagnostic tests were not performed in most cases. Most cases received suboptimal levels of supplemental oxygen, and critical interventions like surfactant replacement therapy and mechanical ventilation were not adequately utilized when available. Conclusion. The study highlights the urgent need for improved diagnosis and management of RDS, emphasizing the importance of increasing clinical suspicion and enhancing training in its clinical management to reduce mortality rates.

Not just surveys and indicators: narratives capture what really matters for health system strengthening.

Health system strengthening remains elusive and challenging. Health systems in many countries in sub-Saharan Africa are frequently characterised as weak, with inadequate management and accountability mechanisms, and poor human and financial resources. Putting patients and staff at the heart of health systems is an essential step towards strengthening them. As one of the three pillars of quality in health care, understanding patient experiences is key to moving towards people-centred care. Yet patient experiences are not a singular concept. Patient narratives can convey individual experiences of illness and health care, which complement and augment epidemiological and public health evidence. These narratives, gathered with rigorous, interview-based research and shared with digital tools (audio and video), can generate persuasive evidence. This evidence has important potential for influencing policy and practice, and for supporting people-centred care, but has not been tested systematically in low-income countries. In the Kenyan context of newborn health, work under way is generating evidence to show the transformative potential of patient narratives.

Developing and testing a clinical care bundle incorporating caffeine citrate to manage apnoea of prematurity in a resource-constrained setting: a mixed methods clinical feasibility study protocol.

BACKGROUND: Apnoea of prematurity (AOP) is a common condition among preterm infants. Methylxanthines, such as caffeine and aminophylline/theophylline, can help prevent and treat AOP. Due to its physiological benefits and fewer side effects, caffeine citrate is recommended for the prevention and treatment of AOP. However, caffeine citrate is not available in most resource-constrained settings (RCS) due to its high cost. Challenges in RCS using caffeine citrate to prevent AOP include identifying eligible preterm infants where gestational age is not always known and the capability for continuous monitoring of vital signs to readily identify apnoea. We aim to develop an evidence-based care bundle that includes caffeine citrate to prevent and manage AOP in tertiary healthcare facilities in Kenya. METHODS: This protocol details a prospective mixed-methods clinical feasibility study on using caffeine citrate to manage apnoea of prematurity in a single facility tertiary-care newborn unit (NBU) in Nairobi, Kenya. This study will include a 4-month formative research phase followed by the development of an AOP clinical-care-bundle prototype over 2 months. In the subsequent 4 months, implementation and improvement of the clinical-care-bundle prototype will be undertaken. The baseline data will provide contextualised insights on care practices within the NBU that will inform the development of a context-sensitive AOP clinical-care-bundle prototype. The clinical care bundle will be tested and refined further during an implementation phase of the quality improvement initiative using a PDSA framework underpinned by quantitative and qualitative clinical audits and stakeholders' engagement. The quantitative component will include all neonates born at gestation age < 34 weeks and any neonate prescribed aminophylline or caffeine citrate admitted to the NBU during the study period. DISCUSSION: There is a need to develop evidence-based and context-sensitive clinical practice guidelines to standardise and improve the management of AOP in RCS. Concerns requiring resolution in implementing such guidelines include diagnosis of apnoea, optimal timing, dosing and administration of caffeine citrate, standardisation of monitoring devices and alarm limits, and discharge protocols. We aim to provide a feasible standardised clinical care bundle for managing AOP in low and middle-income settings.

Prevalence and factors associated with low birth weight among newborns in South Sudan.

Background: WHO estimates that that 13% of babies are delivered low birth weight in Sub-Saharan Africa. Infants with LBW have a twenty times greater risk of dying than infants weighing more than 2500 grams. The neonatal mortality rates in South Sudan is 40 per 1000 live births. LBW significantly contributes to neonatal mortality rates. Objectives: The study aimed at determining the prevalence and factors associated with LBW among newborns. Methods: This was a cross-sectional descriptive study conducted at three hospitals. Completed data on all live births was collected using a structured questionnaire. Univariate and multivariate logistic regression analysis was applied for factors associated with LBW. Adjusted odds ratio with 95% confidence interval was applied and a P value <0.05 was considered statistically significant. Results: We retrieved records of 11845 birth cohorts. The prevalence of LBW among newborns was 11.4%. The prevalence of LBW at Aweil, Juba and Bor was 13.3%, 9.8% and 8.8% respectively. Maternal age less than 20 years and 35 years and above, multigravidity, GA <37 weeks, male sex and multiple pregnancy were significantly associated with LBW. Conclusion: The prevalence of LBW in infants was 11.4%. Associated factors were, maternal age, GA <37 weeks, multigravidity, male sex and multiple pregnancy.

A survey of barriers and facilitators to caffeine use for apnoea of prematurity in low- and middle-income countries.

BACKGROUND: Despite its associated benefits which include better long-term pulmonary and neurodevelopmental outcome, the use of caffeine for apnoea of prematurity (AoP) has been limited in low- and middle-income countries (LMIC). AIM: To better understand current caffeine use, the barriers and facilitators to its use and perceptions and practices in LMIC which have a disproportionately high burden of prematurity. METHODS: An anonymous online global survey was conducted, targeting healthcare providers working and training in paediatrics and/or neonatology in LMIC. RESULTS: A total of 181 respondents in 16 LMIC were included in the analysis; most were physicians working in publicly-funded urban tertiary hospitals. Most had received training in the use of caffeine for AoP (77%), reported expertise (70%) and confidence (96%) in its use, and had access to caffeine (65%). Caffeine availability was reported to be the greatest barrier (48%) and the greatest facilitator (37%). Other common barriers included cost (31%), access (7%) and policies or guidelines on caffeine use (7%); other common facilitators included policies or guidelines on caffeine use (11%), access (10%), staff/other providers' acceptance of caffeine as an appropriate treatment (9%) and the availability of staff to administer caffeine (8%). Most (79%) noted that access to caffeine was important, 92% agreed that caffeine improves quality of care, and 95% agreed that caffeine improves patient outcome. CONCLUSION: Improving availability and access to low-cost caffeine will be key to increasing caffeine use in LMIC.

'Sometimes you are forced to play God ': a qualitative study of healthcare worker experiences of using continuous positive airway pressure in newborn care in Kenya.

​OBJECTIVE: To explore the experiences of using continuous positive airway pressure (CPAP) in newborn care among healthcare workers in Kenya, and to identify factors that would promote successful scale-up. ​DESIGN AND SETTING: A qualitative study using key informant interviews and focus group discussions, based at secondary and tertiary level hospitals in Kenya. ​PARTICIPANTS: Healthcare workers in the newborn units providing CPAP. ​PRIMARY AND SECONDARY OUTCOME MEASURE: Facilitators and barriers of CPAP use in newborn care in Kenya. ​RESULTS: 16 key informant interviews and 15 focus group discussions were conducted across 19 hospitals from September 2017 to February 2018. Main barriers reported were: (1) inadequate infrastructure to support the effective delivery of CPAP, (2) shortage of skilled staff rendering it difficult for the available staff to initiate or monitor infants on CPAP and (3) inadequate knowledge and training of staff that inhibited the safe care of infants on CPAP. Key facilitators reported were positive patient outcomes after CPAP use that increased staff confidence and partnership with caregivers in the management of newborns on CPAP. Healthcare workers in private/mission hospitals had more positive experiences of using CPAP in newborn care as the relevant support and infrastructure were available. ​CONCLUSION: CPAP use in newborn care is valued by healthcare workers in Kenya. However, we identified key challenges that threaten its safe use and sustainability. Further scale-up of CPAP in newborn care should ensure that staff members have ready access to optimal training on CPAP and that there are enough resources and infrastructure to support its use. ETHICS: This study was approved through the appropriate ethics committees in Kenya and the UK (see in text) with written informed consent for each participant.

Effective training-of-trainers model for the introduction of continuous positive airway pressure for neonatal and paediatric patients in Kenya.

Background: Continuous positive airway pressure (CPAP) is a relatively low-cost technology which can improve outcome in neonatal and paediatric patients with respiratory distress. Prior work in a lower middle-income country demonstrated degradation of CPAP skills and knowledge after the initial training. Aims: To determine if a training-of-trainers (ToT) curriculum can decrease gaps in skills and knowledge between first-generation (trained by a United States physician and nurse) and second-generation healthcare providers (trained by local trainers) in Kenya, and to describe the usage pattern, outcome and safety in patients who received CPAP following the trainings. Methods: The first day of training entailed didactic and simulation sessions. On the second day participants were taught how to train others to use CPAP. First- and second-generation healthcare providers were tested on their skills and knowledge. Unpaired t-tests were used to test for equivalence. Prospective data on CPAP usage was collected following the initial trainings. Results: 37 first-generation healthcare providers (16 nurses; 21 physicians, medical/clinical officers) were trained as trainers and 40 second-generation healthcare providers (19 nurses, 21 physicians, medical/clinical officers) trained by first-generation healthcare providers were available for skills and knowledge testing. There were no statistically significant differences between first- and second-generation healthcare providers' skills (90%, 95% CI 87-93 vs 89%, 95% CI 86-92) or knowledge scores (91%, 95% CI 88-93 vs 90%, 95% CI 88-93). A total of 1111 patients were placed on CPAP mostly by nurses (61%), prematurity/acute respiratory distress syndrome was the most common indication, nasal injury/bleeding (2%) was the most common reported adverse event, and the overall mortality rate was 24%. Conclusion: The ToT model was successful, nurses initiated CPAP most commonly, prematurity with acute respiratory distress syndrome was the most common indication, and adverse events were uncommon.

Retinopathy of prematurity in Kenya: prevalence and risk factors in a hospital with advanced neonatal care.

INTRODUCTION: Increased survival of preterm babies in sub-saharan Africa has held to an increasing prevalence of Retinopathy of prematurity (ROP). This study was done to determine the ROP prevalence in a hospital with advanced neonatal care in urban Kenya. METHODS: A hospital-based retrospective review of the records of premature infants screened for ROP between January 2010 and December 2015. Records of all premature infants screened for ROP in the neonatal unit and outpatient eye clinic were extracted. Information on Birth weights, Gestational age, Maternal risk factors (mode of delivery, pre-eclampsia/eclampsia) and Neonatal risk factors (neonatal sepsis, days on oxygen, blood transfusion) was recorded in a questionnaire then analysed. RESULTS: 103 infants were included in the study. Mean gestational age was 29.9 ± 2.2 weeks and the mean birth weight was 1280.1 ± 333.0 grams. Forty-three infants were diagnosed with ROP, a prevalence of 41.7%. Majority of these had Stage 1 or 2 ROP in Zone II, which spontaneously regressed with follow up. Nine infants were diagnosed with vision-threatening ROP (any Zone I disease or Stage 2/3 disease in Zone II with plus disease), a prevalence of 20.9%. All of these underwent laser treatment in the neonatal unit. The most significant risk factor was low gestational age. Other risk factors identified were: low birth weight and blood transfusions. CONCLUSION: ROP prevalence in sub-saharan Africa will match those in middle-income and high income countries in neonatal units with advanced care and low mortality.

Breast-feeding and human immunodeficiency virus infection: assessment of knowledge among clinicians in Kenya.

In Kenya, human immunodeficiency virus (HIV) prevalence ranks among the highest in the world. Approximately 60 000 infections yearly are attributed to vertical transmission including the process of labour and breast-feeding. The vast of the population affected is in the developing world. Clinical officers and nurses play an important role in provision of primary health care to antenatal and postnatal mothers. There are a few studies that have explored the clinicians' knowledge on breast-feeding in the face of HIV and in relation to vertical transmission this being a vital component in prevention of maternal-to-child transmission. The aim of this study was to evaluate clinicians' knowledge on HIV in relation to breast-feeding in Kenya. A cross-sectional survey was conducted to assess knowledge of 161 clinical officers and nurses serving in the maternity and children' wards in various hospitals in Kenya. The participants were derived from all district and provincial referral facilities in Kenya. A preformatted questionnaire containing a series of questions on HIV and breast-feeding was administered to clinicians who were then scored and analyzed. All the 161 participants responded. Majority of clinicians (92%) were knowledgeable regarding prevention of mother-to-child transmission. Regarding HIV and breast-feeding, 49.7% thought expressed breast milk from HIV-positive mothers should be heated before being given. Majority (78.3%) thought breast milk should be given regardless of availability of alternatives. According to 74.5% of the participants, exclusive breast-feeding increased chances of HIV transmission. Two-thirds (66.5%) would recommend breast-feeding for mothers who do not know their HIV status (66.5%). This study observes that a majority of the clinicians have inadequate knowledge on breast-feeding in the face of HIV. There is need to promote training programmes on breast-feeding and transmission of HIV from mother to child. This can be done as in-service training, continuous medical education and as part of the formal training within medical institutions.

Assessment of knowledge on neonatal resuscitation amongst health care providers in Kenya.

INTRODUCTION: Competence in neonatal resuscitation, which represents the most urgent pediatric clinical situation, is critical in delivery rooms to ensure safety and health of newly born infants. The challenges experienced by health care providers during this procedure are unique due to different causes of cardio respiratory arrest. This study aimed at assessing the knowledge of health providers on neonatal resuscitation. METHODS: Data were gathered among 192 health providers drawn from all counties of Kenya. The clinicians were asked to complete questionnaires which were in two parts as; demographic information and assessment of their knowledge by different scenarios which were formatted in the multiple choice questions. Data were analyzed using SPSS version 15.0 for windows. The results are presented using tables. RESULTS: All the participants were aged 23 years and above with at least a certificate training. Most medical providers had heard of neonatal resuscitation (85.4%) with only 23 receiving formal training. The average duration of neonatal training was 3 hours with 50% having missed out on practical exposure. When asked on steps of resuscitation, only 68 (35.4%) of the participants scored above 85%. More than 70% of them considered their knowledge about neonatal resuscitation inadequate and blamed it on inadequate medical training programs. CONCLUSION: Health providers, as the key personnel in the management of neonatal resuscitation, in this survey seem to have inadequate training and knowledge on this subject. Increasing the duration and quality of formal training should be considered during the pre-service medical education to ensure acceptable neonatal outcome.

Interpreting positive cultures of endotracheal aspirates: factors associated with treatment decisions in ventilated neonates.

AIMS: Diagnosis of ventilator-associated pneumonia in newborns is challenging because of ease of colonisation, non-specific chest radiograph changes and lack of a consensus definition. The aims of this study were to review treatment decisions in neonates with culture-positive endotracheal aspirate and to assess impact on respiratory outcomes using blinded review of radiological studies. METHODS: Charts from all very low birthweight neonates ventilated for >48 h and with positive culture were assessed. Chest radiographs were reviewed by a radiologist masked to the grouping of the episode (treated/not treated). Clinical, investigational and radiological features used in practice were assessed on impact on treatment decisions. Association between treatment and outcomes was assessed. RESULTS: Seventy-four episodes of culture-positive endotracheal aspirate were analysed in 38 babies. Fifty-eight episodes were treated with antibiotics. Gestational age at birth and birthweight in both groups (treated vs. non-treated) were statistically comparable (25.5 ± 3.1 vs. 27.2 ± 2.3 weeks and 809 ± 302 vs. 870 ± 262 g). Comparative chest radiographs were available in 51 of 58 treated episodes; deterioration was noted in 42 (82.3%). Ventilatory parameters were significantly higher in the treatment group and showed a significant improvement after antibiotics. Twenty-three babies developed chronic lung disease. Odds ratio (of having chronic lung disease when treatment is initiated) was 4.5 (95% confidence interval = 0.97-20.8, P= 0.06). CONCLUSIONS: Treated culture-positive aspirate episodes were accompanied by higher ventilatory requirements, increased symptoms and elevated septic markers. Need for treatment was associated with greater likelihood of developing chronic lung disease.

Predicting perinatal outcome through changes in umbilical artery Doppler studies after antenatal corticosteroids in the growth-restricted fetus.

OBJECTIVE: To investigate whether persistently absent umbilical artery end-diastolic flow in the intrauterine growth-restricted fetus after betamethasone administration is associated with altered perinatal outcomes. METHODS: This is a retrospective cohort study of 92 pregnancies complicated by intrauterine growth restriction (IUGR) and absent end-diastolic flow in which antenatal betamethasone was given. Predefined maternal outcomes (maternal age, gestational age at diagnosis of absent end-diastolic flow, gestational age at delivery, preexisting medical conditions) and neonatal outcomes (including birth weight; perinatal mortality; duration of neonatal intensive care unit admission; requirement for intubation, assisted ventilation, inotropic support; duration of supplemental oxygen, assisted ventilation; respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage) were analyzed. RESULTS: Betamethasone administration was associated with a transient return of end-diastolic umbilical artery flow in 58 pregnancies (63%) and persistent absent end-diastolic flow in 34 (37%). Persistent absent end-diastolic flow was seen more frequently in women with prepregnancy medical disorders (59% compared with 24%, P<.001). Neonates from the persistent absent end-diastolic flow subgroup were more likely to require assisted ventilation (93.1% compared with 73.5%, P=.03) and to have longer durations of assisted ventilation (median time 30 days compared with 4 days, P=.03) and supplemental oxygen (median time 45 days compared with 4 days, P=.04). CONCLUSION: Betamethasone administration is associated with a transient return of end-diastolic flow in two thirds of pregnancies complicated by IUGR and umbilical artery absent end-diastolic flow. Persistent absent end-diastolic flow in the umbilical artery after betamethasone administration may identify a subgroup of fetuses with IUGR at further heightened perinatal risk that, as neonates, are more likely to require assisted ventilation and a longer duration of ventilation and supplemental oxygen.
