The whole is more than the sum of the parts: establishing an enabling health system environment for reducing acute child malnutrition in a rural South African district

The Meso-Level in Quality Improvement: Perspectives From a Maternal-Neonatal Health Partnership in South Africa

BACKGROUND

Sustained implementation of facility-level quality improvement (QI) processes, such as plan-do-study-act cycles, requires enabling meso-level environments and supportive macro-level policies and strategies. Although this is well recognised, there is little systematic empirical evidence on roles and capacities, especially at the immediate meso-level of the system, that sustain QI strategies at the frontline.

METHODS

In this paper we report on qualitative research to characterize the elements of a quality and outcome-oriented meso-level, focused on sub/district health systems (DHSs), conducted within a multi-level initiative to improve maternal-newborn health (MNH) in three provinces of South Africa. Drawing on the embedded experience and tacit knowledge of core project partners, obtained through in-depth interviews (39) and project documentation, we analysed thematically the roles, capacities and systems required at the meso-level for sustained QI, and experiences with strengthening the meso-level.

RESULTS

Meso-level QI roles identified included establishing and supporting QI systems and strengthening delivery networks. We propose three elements of system capacity as enabling these meso-level roles: (1) leadership stability and capacity, (2) the presence of formal mechanisms to coordinate service delivery processes at sub-district and district levels (including governance, referral and outreach systems), and (3) responsive district support systems (including quality oriented human resource, information, and emergency medical services [EMS] management), embedded within supportive relational eco-systems and appropriate decision-space. While respondents reported successes with system strengthening, overall, the meso-level was regarded as poorly oriented to and even disabling of quality at the frontline.

CONCLUSION

We argue for a more explicit orientation to quality and outcomes as an essential district and sub-district function (which we refer to as meso-level stewardship), requiring appropriate structures, processes, and capacities.

Strengthening the Diagnosis and Treatment of Malnutrition Through Increased Nurse Involvement: A Quality Improvement Project From Pediatric Wards in Mozambique

BACKGROUND

Childhood acute malnutrition continues to be a serious health problem in many low-resource settings in Africa. On pediatric wards in Mozambique, missed opportunities for timely diagnosis and treatment of malnutrition may lead to poor health outcomes. To improve inpatient nutritional care, a quality improvement (QI) project was implemented that aimed to engage pediatric nurses in inpatient malnutrition diagnosis and treatment.

METHODS

In 2 Mozambican referral hospitals, for 6 months, the Plan-Do-Study-Act framework for QI was implemented to identify key drivers of the following measures: having complete anthropometric evaluation documented at admission, 3 or more weight measurements per hospitalization week, documentation of nutritional therapy for eligible patients, and documentation of referral for outpatient nutritional rehabilitation after discharge. Clinical data were abstracted from hospital charts and entered into an EpiInfo database, including a 3-month observation period after the project, and analyzed retrospectively.

RESULTS

A total of 2,208 children from wards other than malnutrition were included in the analysis. Complete anthropometric evaluation at admission improved from 24.4% 2 months before the QI project to 80.1% during and 75.2% in the 3 months after the project (P<.001). The percentage of patients with 3 or more weight measurements per hospitalization week rose from 22.3% to 82.8% during and 75.0% after the project (P<.001). Documentation of nutritional therapy increased from 58.8% before to 67.1% during and 70.6% after the project (P=.54), and documentation of referral for outpatient nutritional rehabilitation after discharge decreased from 55.9% to 54.9% during and increased to 70.6% after the project, (P<.001).

CONCLUSION

Nurse engagement may lead to important advancements in the diagnosis and treatment of acute malnutrition in pediatric wards other than malnutrition in Mozambique. Task-sharing, particularly nurse engagement, in combination with QI methodology, may be considered for wards in similar settings with a high burden of malnutrition.

Factors influencing the implementation of severe acute malnutrition guidelines within the healthcare referral systems of rural subdistricts in North West Province, South Africa

Severe acute malnutrition (SAM) is associated with 30.9% of South Africa's audited under-five children deaths regardless of available guidelines to reduce SAM at each level of a three tyre referral system. Existing research has explored and offered solutions for SAM guidelines implementation at each referral system level, but their connectedness in continuation of care is under-explored. Therefore, I examined implementation of SAM guidelines and factors influencing implementation within subdistrict referral systems. An explanatory qualitative case study design was used. The study was conducted in two subdistricts involving two district hospitals; three community health centres, four clinics, and two emergency service stations. Between February to July 2016 and 2018, data were collected using 39 in-depth interviews with clinical, emergency service and administrative personnel; 40 reviews of records of children younger than five years; appraisals of nine facilities involved in referrals and observations. Thematic content analysis was used to analyse all data except records which were aggregated to elicit whether required SAM guidelines' steps were administered per case reviewed. Record reviews revealed SAM diagnosis discrepancies demonstrated by incomplete anthropometric assessments; non-compliance to SAM management guidelines was noted through skipping some critical steps including therapeutic feeding at clinic level. Record reviews further revealed variations of referral mechanisms across subdistricts, contradictory documentation within records, and restricted continuation of care. Interviews, observations and facility appraisals revealed that factors influencing these practices included inadequate clinical skills; inconsistent supervision and monitoring; unavailability of subdistrict specific referral policies and operational structures; and suboptimal national policies on therapeutic food. SAM diagnosis, management, and referrals within subdistrict health systems need to be strengthened to curb preventable child deaths. Implementation of SAM guidelines needs to be accompanied by job aids and supervision with standardised tools; subdistrict-specific referral policies and suboptimal national policies to ensure availability and accessibility of therapeutic foods.

Health managers and community representatives' views of a system-wide intervention to strengthen public healthcare in the Free State, South Africa

Background

A system-wide health system strengthening (HSS) initiative, the Health Systems Governance and Accountability (HSGA) intervention, was developed, translated to policy, and implemented in the Free State province. This study assessed health managers (HMs) and community representatives' (CRs) views of the intervention and whether it improved integration and performance.

Method

A questionnaire survey among 147 HMs and 78 CRs and 14 focus group discussions (FGDs) with a mean of 10.3 participants and a total of 102 HMs and 42 CRs, were conducted. The questionnaire and FGD data were descriptively and thematically analysed to triangulate findings.

Results

Many HMs (44%) mostly positioned at the operational levels indicated that implementation of the HSGA intervention did contribute to integration of health services. Most CRs (54%) believed that communities were actively involved in the intervention. However, both the self-administered questionnaire and the FGD data evidenced lack of policy awareness among, especially, operational-level HMs.

Conclusion

From the perspectives of HMs and CRs, the implementation of the intervention was viewed as a step forward in strengthening public healthcare to respond to system deficiencies in the Free State province. Earlier engagement of especially operational-level HMs during reforms may be beneficial in successfully implementing HSS interventions.

The Multidimension of Malnutrition among School Children in a Rural Area, South Africa: A Mixed Methods Approach

To address childhood malnutrition, the use of multifaceted methodologies, such as mixed methods research, is required to inform effective and contextual interventions. However, this remains limited in studying malnutrition among school children in a South African context, notwithstanding its persistence. We adopted a convergent parallel mixed methods design to best understand the magnitude of malnutrition through multilevel influences in a rural area. A quantitative survey determined the magnitude of malnutrition and associated factors among school children and their mothers (n = 508), parallel to a qualitative study, which explored mothers' insights into the influences of child growth and nutrition in interviews using seven focus group discussions. Mixed methods integration was achieved through convergence of the quantitative constructs developed from measured variables for malnutrition and related factors with ten emergent qualitative themes using a joint display analysis to compare the findings and generate meta-inferences. Qualitative themes on food unavailability and affordability, poor feeding beliefs and practices, and decision to purchase foods were consistent with the quantified poor socio-demographic status of mothers. Furthermore, the qualitative data explained the high prevalence of undernutrition among children but did not corroborate the high estimated households' food security in the quantitative survey. The misperceptions of mothers on child growth agreed with limited food knowledge as well as lack of knowledge on child growth gathered during the survey. Moreover, mothers believed that their children were growing well despite the high presence of childhood undernutrition. Mothers further overrated the effectiveness of school feeding programmes in providing healthy food to children as compared to their household food. They reported high incidence of food allergies, diarrhea, and vomiting caused by food consumed at school which resulted in children not eating certain foods. This might have impacted on the nutritional status of children since mothers depended on the school feeding program to provide food for their children. The ambiguity of cultural influences in relation to child growth was evident and substantiated during qualitative interview. Mixed methods integration offered a better understanding of malnutrition from empirical findings on interrelated factors at child, maternal, household, and school levels. This study points to a need for multilevel, informed, and contextual multidimensional interventions to contribute towards addressing childhood malnutrition in South Africa.

Early Reflections on Mphatlalatsane, a Maternal and Neonatal Quality Improvement Initiative Implemented During COVID-19 in South Africa

Despite global progress in reducing maternal and neonatal mortality and stillbirths, much work remains to be done to achieve the Sustainable Development Goals. Reports indicate that coronavirus disease (COVID-19) disrupts the provision and uptake of routine maternal and neonatal health care (MNH) services and negatively impacts cumulative pre-COVID-19 achievements. We describe a multipartnered MNH quality improvement (QI) initiative called Mphatlalatsane, which was implemented in South Africa before and during the COVID-19 pandemic. The initiative aimed to reduce the maternal mortality ratio, neonatal mortality rate, and stillbirth rate by 50% between 2018 and 2022. The multifaceted design comprises QI and other intervention activities across micro-, meso-, and macrolevels, and its area-based approach facilitates patients' access to MNH services. The initiative commenced 6 months pre-COVID-19, with subsequent adaptation necessitated by COVID-19. The initial focus on a plan-do-study-act QI model shifted toward meeting the immediate needs of health care workers (HCWs), the health system, and health care managers arising from COVID-19. Examples include providing emotional support to staff and streamlining supply chain management for infection control and personal protection materials. As these needs were addressed, Mphatlalatsane gradually refocused HCWs' and managers' attention to recognize the disruptions caused by COVID-19 to routine MNH services. This gradual reprioritization included the development of a risk matrix to help staff and managers identify specific risks to service provision and uptake and develop mitigating measures. Through this approach, Mphatlalatsane led to an optimization case using existing resources rather than requesting new resources to build an investment case, with a responsive design and implementation approach as the cornerstone of the initiative. Further, Mphatlalatsane demonstrates that agile and context-specific responses to crises such as the COVID-19 pandemic can mitigate such threats and maintain interventions to improve MNH services.

Overview

BACKGROUND

South Africa (SA) faces multiple health challenges. Quantifying the contribution of modifiable risk factors can be used to identify and prioritise areas of concern for population health and opportunities for health promotion and disease prevention interventions.

OBJECTIVE

To estimate the attributable burden of 18 modifiable risk factors for 2000, 2006 and 2012.

METHODS

Comparative risk assessment (CRA), a standardised and systematic approach, was used to estimate the attributable burden of 18 risk factors. Risk exposure estimates were sourced from local data, and meta-regressions were used to model the parameters, depending on the availability of data. Risk-outcome pairs meeting the criteria for convincing or probable evidence were assessed using relative risks against a theoretical minimum risk exposure level to calculate either a potential impact fraction or population attributable fraction (PAF). Relative risks were sourced from the Global Burden of Disease, Injuries, and Risk Factors (GBD) study as well as published cohort and intervention studies. Attributable burden was calculated for each risk factor for 2000, 2006 and 2012 by applying the PAF to estimates of deaths and years of life lost from the Second South African National Burden of Disease Study (SANBD2). Uncertainty analyses were performed using Monte Carlo simulation, and age-standardised rates were calculated using the World Health Organization standard population.

RESULTS

Unsafe sex was the leading risk factor across all years, accounting for one in four DALYs (26.6%) of the estimated 20.6 million DALYs in 2012. The top five leading risk factors for males and females remained the same between 2000 and 2012. For males, the leading risks were (in order of descending rank): unsafe sex; alcohol consumption; interpersonal violence; tobacco smoking; and high systolic blood pressure; while for females the leading risks were unsafe sex; interpersonal violence; high systolic blood pressure; high body mass index; and high fasting plasma glucose. Since 2000, the attributable age-standardised death rates decreased for most risk factors. The largest decrease was for household air pollution (-41.8%). However, there was a notable increase in the age-standardised death rate for high fasting plasma glucose (44.1%), followed by ambient air pollution (7%).

CONCLUSION

This study reflects the continued dominance of unsafe sex and interpersonal violence during the study period, as well as the combined effects of poverty and underdevelopment with the emergence of cardiometabolic-related risk factors and ambient air pollution as key modifiable risk factors in SA. Despite reductions in the attributable burden of many risk factors, the study reveals significant scope for health promotion and disease prevention initiatives and provides an important tool for policy makers to influence policy and programme interventions in the country.

Estimating the changing burden of disease attributable to childhood stunting, wasting and underweight in South Africa for 2000, 2006 and 2012

Background. National estimates of childhood undernutrition display uncertainty; however, it is known that stunting is the most prevalent deficiency. Child undernutrition is manifest in poor communities but is a modifiable risk factor. The intention of the study was to quantify trends in the indicators of child undernutrition to aid policymakers. Objectives. To estimate the burden of diseases attributable to stunting, wasting and underweight and their aggregate effects in South African (SA) children under the age of 5 years during 2000, 2006 and 2012. Methods. The study applied comparative risk assessment methodology. Data sources for estimates of prevalence and population distribution of exposure in children under 5 years were the National Food Consumption surveys and the SA National Health and Nutrition Examination Survey conducted close to the target year of burden. Childhood undernutrition was estimated for stunting, wasting and underweight and their combined ‘aggregate effect’ using the World Health Organization (WHO) 2006 standard. Population-attributable fractions for the disease outcomes of diarrhoea, lower respiratory tract infections, measles and protein-energy malnutrition were applied to SA burden of disease estimates of deaths, years of life lost, years lived with a disability and disability-adjusted life years for 2000, 2006 and 2012. Results. Among children aged under 5 years between 1999 and 2012, the distribution of anthropometric measurements <‒2 standard deviations from the WHO median showed little change for stunting (28.4% v. 26.6%), wasting (2.6% v. 2.8%) and underweight (7.6% v. 6.1%). In the same age group in 2012, attributable deaths due to wasting and aggregated burden accounted for 21.4% and 33.2% of the total deaths, respectively. Attributable death rates due to wasting and aggregate effects decreased from ~310 per 100 000 in 2006 to 185 per 100 000 in 2012. Conclusion. The study shows that reduction of childhood undernutrition would have a substantial impact on child mortality. We need to understand why we are not penetrating the factors related to nutrition of children that will lead to reducing levels of stunting.

Scaling Up Improved Inpatient Treatment of Severe Malnutrition: Key Factors and Experiences From South Africa, Bolivia, Malawi, and Ghana

We report lessons learned in 4 countries from scaling up the implementation of World Health Organization guidelines on inpatient management of severe acute malnutrition within routine health services. We provide evidence that implementation is achievable at scale within different contexts and health systems.

Severe acute malnutrition (SAM) can have high mortality, especially in very ill children treated in the hospital. Many medical and nursing schools do not adequately, if at all, teach how to manage children with SAM. There is a dearth of experienced practitioners and trainers to serve as exemplars of good practice or participate in capacity development. We consider 4 country studies of scaling up implementation of WHO guidelines for improving the inpatient management of SAM within under-resourced public sector health services in South Africa, Bolivia, Malawi, and Ghana. Drawing on implementation reports, qualitative and quantitative data from our research, prospective and retrospective data collection, self-reflection, and our shared experiences, we review our capacity-building approaches for improving quality of care, implementation effectiveness, and lessons learned. These country studies provide important evidence that improved inpatient management of SAM is scalable in routine health services and scalability is achievable within different contexts and health systems. Effectiveness in reducing inpatient SAM deaths appears to be retained at scale.

The country studies show evidence of impact on mortality early in the implementation and scaling-up process. However, it took many years to build workforce capacity, establish monitoring and mentoring procedures, and institutionalize the guidelines within health systems. Key features for success included collaborations to build capacity and undertake operational research and advocacy for guideline adoption; specialist teams to mentor and build confidence and competency through supportive supervision; and political commitment and administrative policies for sustainability. For frontline staff to be confident in their ability to deliver appropriate care competently, an enabling environment and supportive policies and processes are needed at all levels of the health system.

Impact of new health care reform on enabling environment for children’s health in China: An interrupted time-series study

Background

Creating an enabling environment (EE) can help foster the development and health of children. The Chinese government implemented a new health care reform (NHR) in 2009 in a move to promote an EE for health. The purpose of this study was to evaluate the impact of the NHR on EE for children’s health.

Methods

An interrupted time-series analysis was used to evaluate the changes in the EE before and after 2009 in China. This study analysed the EE through five quantitative indicators, including policy element coverage rate (PECR), service meeting with children’s needs rate (SMCNR), multisector participation rate (MPR), and accountability mechanism clarity rate (AMCR), based on the content analysis of available public policy documents (updated as of 2019) from 31 provinces in mainland China, and the number of health care personnel of maternity and child care centres per 10 000 population (HP per 10 000 population), based on the 2002–2019 China Health Statistical Yearbook and China Statistical Yearbook.

Results

The average values of PECR, SMCNR, and MPR increased rapidly to 90.96%, 82.46%, and 81.31%, respectively, in 2019, representing a higher value compared to the AMCR (7.38%). The NHR promoted the EE, in which HP per 10 000 population showed the fastest increase (β₁ = 0.03, P < 0.01; β₃ = 0.10, P < 0.01), followed by SMCNR (β₁ = 0.94, P < 0.01; β₃ = 1.83, P < 0.01), AMCR (β₁ = 0.13, P < 0.01; β₃ = 0.24, P = 0.14), MPR (β₁ = 1.35, P < 0.01; β₃ = 2.47, P < 0.01) and PECR (β₁ = 1.43, P < 0.01; β₃ = 1.47, P < 0.01).

Conclusions

The NHR has a positive impact on the EE, especially on the human resources and service provision for children. Efforts should be intensified to improve the clarity of the accountability mechanism of the health-related sectors.

Expressions of actor power in implementation: a qualitative case study of a health service intervention in South Africa

Background

Implementation frameworks and theories acknowledge the role of power as a factor in the adoption (or not) of interventions in health services. Despite this recognition, there is a paucity of evidence on how interventions at the front line of health systems confront or shape existing power relations. This paper reports on a study of actor power in the implementation of an intervention to improve maternal, neonatal and child health care quality and outcomes in a rural district of South Africa.

Methods

A retrospective qualitative case study based on interviews with 34 actors in three ‘implementation units’ – a district hospital and surrounding primary health care services – of the district, selected as purposefully representing full, moderate and low implementation of the intervention, some three years after it was first introduced. Data are analysed using Veneklasen and Miller’s typology of the forms of power – namely ‘power over’, ‘power to’, ‘power within’ and ‘power with’.

Results

Multiple expressions of actor power were evident during implementation and played a plausible role in shaping variable implementation, while the intervention itself acted to change power relations. As expected, a degree of buy-in of managers (with power over) in implementation units was necessary for the intervention to proceed. Beyond this, the ability to mobilise collective action (power with), combined with support from champions with agency (power within) were key to successful implementation. However, local empowerment may pose a threat to hierarchical power (power over) at higher levels (district and provincial) of the system, potentially affecting sustainability.

Conclusions

A systematic approach to the analysis of power in implementation research may provide insights into the fate of interventions. Intervention designs need to consider how they shape power relations, especially where interventions seek to widen participation and responsiveness in local health systems.

Improving recognition and management of children with complicated severe acute malnutrition at a tertiary referral hospital in Malawi: a quality improvement initiative

BACKGROUND

Severe acute malnutrition (SAM) is common in low-income countries and is associated with high mortality in young children.

OBJECTIVE

To improve recognition and management of SAM in a tertiary hospital in Malawi.

METHODS

The impact of multifaceted quality improvement interventions in process measures pertaining to the identification and management of SAM was assessed. Interventions included focused training for clinical staff, reporting process measures to staff, and mobile phone-based group messaging for enhanced communication. This initiative focused on children aged 6-36 months admitted to Kamuzu Central Hospital in Malawi from September 2019 to March 2020. Before-after comparisons were made with baseline data from the year before, and process measures within this intervention period which included three plan-do-study-act (PDSA) cycles were compared.

RESULTS

During the intervention period, 418 children had SAM and in-hospital mortality was 10.8%, which was not significantly different from the baseline period. Compared with the baseline period, there was significant improvement in the documentation of full anthropometrics on admission, blood glucose test within 24 hours of admission and HIV testing results by discharge. During the intervention period, amidst increasing patient census with each PDSA cycle, three process measures were maintained (documentation of full anthropometrics, determination of nutritional status and HIV testing results), and there was significant improvement in blood glucose documentation.

CONCLUSION

Significant improvement in key quality measures represents early progress towards the larger goal of improving patient outcomes, most notably mortality, in children admitted with SAM.

Risk factors for mortality and management of children with complicated severe acute malnutrition at a tertiary referral hospital in Malawi

BACKGROUND

Severe acute malnutrition (SAM) is a major cause of childhood mortality in resource-limited settings. The relationship between clinical factors and adherence to the 'WHO 10 Steps' and mortality in children with SAM is not fully understood.

METHODS

Data from an ongoing prospective observational cohort study assessing admission characteristics, management patterns and clinical outcome in children aged 6-36 months admitted to a tertiary hospital in Malawi from September 2018 to September 2019 were analysed. Data clerks independently collected data from patients' charts. Demographics, clinical and nutritional status, identification of SAM and adherence to the 'WHO 10 Steps' were summarised. Their relationship to in-hospital mortality was assessed using multivariable logistic regression.

RESULTS

Of the 6752 patients admitted, 9.7% had SAM. Mortality was significantly higher in those with SAM (10.1% vs 3.8%, p < 0.001). Compared with independent assessment anthropometrics, clinicians appropriately documented SAM on admission in 39.5%. The following factors were independently associated with mortality: kwashiorkor [adjusted odds ratio (aOR) 5.14, 95% confidence interval (CI) 1.27-20.78], shock (aOR 18.54, 95% CI 3.87-88.90), HIV-positive (aOR 5.32, 95% CI 1.76-16.09), SAM documented on admission (aOR 2.41, 95% CI 1.11-5.22), documentation of blood glucose within 24 hrs (aOR 3.97, 95% CI 1.90-8.33) and IV fluids given without documented shock (aOR 3.13, 95% CI 1.16-8.44).

CONCLUSION

HIV infection remains an important predictor of mortality in children with SAM. IV fluids should be avoided in those without shock. Early identification of SAM by the clinical team represents a focus of future quality improvement interventions at this facility.

Action research and health system strengthening: the case of the health sector support programme in Mauritania, West Africa

Background

Access to qualitative and equitable healthcare is a major challenge in Mauritania. In order to support the country’s efforts, a health sector strengthening programme was set up with participatory action research at its core. Reinforcing a health system requires a customised and comprehensive approach to face the complexity inherent to health systems. Yet, limited knowledge is available on how policies could enhance the performance of the system and how multi-stakeholder efforts could give rise to changes in health policy. We aimed to analyse the ongoing participatory action research and, more specifically, see in how far action research as an embedded research approach could contribute to strengthening health systems.

Methods

We adopted a single-case study design, based on two subunits of analysis, i.e., two selected districts. Qualitative data were collected by analysing country and programme documents, conducting 12 semi-structured interviews and performing participatory observations. Interviewees were selected based on their current position and participation in the programme. The data analysis was designed to address the objectives of the study, but evolved according to emerging insights and through triangulation and identification of emergent and/or recurrent themes along the process.

Results

An evaluation of the progress made in the two districts indicates that continuous capacity-building and empowerment efforts through a participative approach have been key elements to enhance dialogue between, and ownership of, the actors at the local health system level. However, the strong hierarchical structure of the Mauritanian health system and its low level of decentralisation constituted substantial barriers to innovation. Other constraints were sociocultural and organisational in nature. Poor work ethics due to a weak environmental support system played an important role. While aiming for an alignment between the flexible iterative approach of action research and the prevailing national linear planning process is quite challenging, effects on policy formulation and implementation were not observed. An adequate time frame, the engagement of proactive leaders, maintenance of a sustained dialogue and a pragmatic, flexible approach could further facilitate the process of change.

Conclusion

Our study showcases that the action research approach used in Mauritania can usher local and national actors towards change within the health system strengthening programme when certain conditions are met. An inclusive, participatory approach generates dynamics of engagement that can facilitate ownership and strengthen capacity. Continuous evaluation is needed to measure how these processes can further develop and presume a possible effect at policy level.
