Multi-country case studies on planning RMNCH services using WISN methodology: Bangladesh, Ghana, Kenya, Sultanate of Oman and Papua New Guinea
Human Resources for Health volume 19, Article number: 155 (2022)
Globally, many countries are adopting evidence-based workforce planning that facilitates progress towards achieving sustainable development goals for reproductive, maternal newborn and child health. We reviewed case studies on workforce planning for reproductive maternal newborn child health services at primary care level facilities using workload indicators of staffing need in five countries.
Using available workload indicators for staffing need reports from Bangladesh, Ghana, Kenya, Sultanate of Oman and Papua New Guinea, we generated descriptive statistics to explore comparable workload components and activity standards, health service delivery models with an emphasis on the primary care levels and the specific health occupations offering interventions associated with reproductive maternal, newborn and child health services.
The health services delivery models vary from one country to another. The results showed variability in the countries, in the workload components and activity standards of each regardless of facility level or occupational groups involved. All the countries have decentralized health services with emphasis on comprehensive primary care. Reproductive, maternal and new-born child health care services include antenatal, postnatal, immunization, family planning, baby wellness clinics, delivery and management of integrated minor childhood illnesses. Only Sultanate of Oman offers fertility services at primary care. Kenya has expanded interventions in the households and communities.
Since the health care services models, health services delivery contexts and the health care worker teams vary from one country to another, the study therefore concludes that activity standards cannot be adopted or adapted from one country to another despite having similar workload components. Evidence based workforce planning must be context-specific, and therefore requires that each country develop its own workload components and activity standards aligned to their local contexts.
Health workforce policies based on sound evidence is essential to ensure the provision of quality health services and to achieve the national set targets of universal health coverage (UHC) and sustainable development goals (SDGs) [1, 2]. There is an accumulating body of evidence that increased availability of skilled health workforce is linked to improved health outcomes including reproductive, maternal, newborn and child health (RMNCH) [3, 4]. However, there are significant variations in the availability, distribution and utilization of primary health care workers, services provided and time taken to undertake any given intervention . This paper focuses on evidence-based workforce planning using workload components and activity standards  at the different levels of care for the specific health occupations to achieve RMNCH services in five countries.
The Nairobi Summit on ICPD25 held in November 2019 brought together over 8300 delegates from about 170 countries and partners who made bold commitments to transform the world by ending all maternal deaths, unmet need for family planning and gender-based violence and harmful practices against women and girls by 2030 . The meeting aimed at renewing, re-energizing communities to work together to support strengthening of national health systems in order to enable accelerated delivery of key interventions for improved RMNCH outcomes along the continuum of care. This cannot be achieved without well planned adequate healthcare providers.
Primary health care (PHC) has been proven to be a highly effective and efficient way to address the leading causes and risks of poor health and well-being today, as well as handling the emerging challenges that threaten health and well-being tomorrow. It has also been shown to be a good value investment, as there is evidence that quality primary health care reduces total healthcare costs and improves efficiency . Countries that adopt health systems with strong emphasis on strengthening the primary care levels are more likely to have better and more equitable outcomes due to being more efficient and having lower costs for essential health services . This in turn, leads to improved client satisfaction than those whose systems have only a weak orientation to PHC. Universal access to reproductive, maternal, newborn and child health is one of the key components of the sustainable development goals (SDGs) . The World Health Organization (WHO) and other health partners continue to support countries to strengthen health systems and to cultivate enabling environments where skilled health professionals provide quality reproductive, maternal, newborn and child health services 
In countries like Bangladesh, Ghana, Kenya, Sultanate of Oman and Papua New Guinea, primary care is emphasized as a strategic priority for increasing access to essential services including RMNCH services [12,13,14,15,16]. As countries work towards achieving UHC and SDGs, discussions relating to evidence based workforce planning, deployment and management are progressively getting attention in many countries’ policies. Human resources for health are increasingly considered an important change factor and highly relevant to economic development .
The Global Strategy for Women’s, Children’s and Adolescents’ Health (2016–2030)  envisions a world in which every woman, child and adolescent in every setting realizes their rights to physical and mental health and well-being, has social and economic opportunities, and is able to participate fully in shaping prosperous and sustainable societies. It provides a significant opportunity to broaden government’s actions to commit financing and improve universal access to sexual and reproductive health rights as part of the universal health coverage and sustain gains made drawing on demographic diversity to drive economic growth. The Global Strategy on Human Resources for Health (GSHRH) estimates a minimum threshold of 4.45 physicians, nurses and midwives per 1000 population as necessary for making sustained progress towards the SDGs and other health goals for meeting the health needs of a country. With many primary health care models and health occupations worldwide, increased attention is being focused on human resources planning and management. Specifically, human resources are one of three principle health system inputs, with the other two major inputs being physical capital and consumables. To achieve a reasonably sized health workforce that can meet the population needs, countries, need to shape national and subnational level policies and relevant health goals . Although WISN is the most methodologically consistent and widely used evidence-based health workforce planning tool, cross-country comparisons of the service standards and contexts that drive WISN-based workforce requirements have not been scientifically documented.
This paper examines how evidence-based health workforce needs were estimated for reproductive, maternal newborn child health (RMNCH) services at primary health care level health facilities in Bangladesh, Ghana, Kenya, Sultanate of Oman and Papua New Guinea using the WISN method.
To describe the five countries’ workload components, we purposively narrowed down to those countries that had used the workload indicators of staffing need (WISN) methodology to generate evidence enabling policy changes or new initiatives in the country. We focused on primary health care facilities in service areas that offer RMNCH interventions. A total of 8 RMNCH interventions were identified, assessed and selected for this review with the specific health worker occupations that performed the interventions. Key variables chosen for this study included the workload components and activity or service standards for health service activities. This was a comparative study that involved five countries—Bangladesh, Ghana, Kenya, Sultanate of Oman and Papua New Guinea.
In each country under study, the WISN implementation was undertaken by three committees namely the Steering Committee, technical task force (TTF) and the Expert Working Groups (EWG). The committees had specific roles in the WISN process to ensure accurate implementation. The committee members were oriented with the support of WHO and other partners. Each country’s expert working groups (EWG) independently developed workload components and activity standards within their local contexts under the guidance of technical task force. The countries in the study focused on all the interventions undertaken in the health facilities however; our current study only discusses selected RMNCH services.
Cross-country analysis followed core principles of qualitative data analysis. The authors thoroughly reviewed all country reports to pick out the RMNCH services offered at primary care facilities. Thematic analysis was then completed to identify common services, occupations performing them, and the time taken to undertake the workload components.
Health service delivery models across countries
The delivery models and services packages differ from one country to another with different health workers and services for the essential RMNCH services. Papua New Guinea’s governance system is highly decentralized with each of the provinces responsible for delivery of health and other social services supported by legislative laws. There are seven levels of PNG’s health service delivery model as outlined by the National Health Services Standards (NHSS): aid posts, sub-health centres/community health posts, health centres, district hospitals, provincial hospitals, regional hospitals and the national referral hospitals.
Kenya’s healthcare system is decentralized with each of the counties responsible for health services. The community unit is the foundation of the service delivery system with both demand creation and health promotion services. The physical level of the health system is the dispensary and health centre. The County referral health services comprise all level 4 and level 5 secondary hospitals and services in the country. Finally, the national referral services comprise all tertiary level 6 referral hospitals, national reference laboratories and services, blood transfusion services, research and training institutions providing highly specialized care.
The health service delivery system in the Sultanate of Oman is divided into three levels: primary, secondary, and tertiary. The primary level comprises of health centers and extended health centers (polyclinics), secondary level to district and regional hospitals, and tertiary level to the four national hospitals. Within this system, the Ministry of Health (MoH) provides more than 80% of the health services.
Bangladesh has an extensive healthcare delivery network from the central to the rural communities. The network is divided into three levels of care i.e. primary, secondary and tertiary levels. The primary level includes health facilities built at wards (household/community) level, Union (several wards constitute a Union) level and Upazila or sub-district level (several Unions constitute an Upazila). Secondary level includes health facilities built at district cities and tertiary level facilities are built at district, divisional and capital cities.
Ghana is administratively divided into regions, districts, sub-districts and communities. The delivery of health services is operationally and administratively aligned with these structures. The public health service delivery is entrusted to semi-autonomous establishments, namely, the Ghana Health Service (GHS) for primary levels of care and Teachings Hospitals (THs) for tertiary and quaternary levels of care.
Analysing the workload components and activity standards for RMNCH services using WISN
In implementing WISN, one of the key steps is the definition of the health occupation activities that make up their daily schedule, which are termed as the workload components. The process of establishing health service activities and the activity standards in the five countries was done by the EWG based on their experiences in the health facilities and their competencies. Typically, workloads are categorised into three different workload components namely health service activities, support activities and additional activities. This multi-country study focuses on health service activities and their corresponding activity/service standards. Health service activities are all those tasks performed by all members of that staff category (an occupational group) based on their training and competencies. They have regular statistics collected on them. They involve direct provision of health services to patients or clients. Using this definition, we synthesized the workload components and activity standards for RMNCH services at the primary health care level for the five countries which cover pre-natal, pregnancy, childbirth, postnatal and childhood. Table 2 provides a summary of the RMNCH services provided at PHC level across the five countries. Further details can be found in Appendix (Tables 9, 10, 11, 12 and 13).
The results show that the five countries plan and provide these essential services differently. The results also showed differences in the countries, in the workload components and activity standards of each facility level or occupational groups involved. In Papua New Guinea health workers at all the primary care services offer ANC services for 15 min per client. In Sultanate of Oman ANC services are offered for 45 min per client, 25 min by medical doctors and 20 min by nurses. Either of the two can offer the services at any one time. Papua New Guinea and Sultanate of Oman thus plan for the same time for ANC services. Kenya estimates more time for the 1st ANC at 35 min per client and 15 min for the subsequent ANC visits. In Ghana, health workers also spent 25 min per client on the first ANC visit and 15 min for subsequent ones. In Bangladesh, health workers also spent 60 min per client on the first ANC visit and 30 min for subsequent ones. Out of the five countries under review only Sultanate of Oman provided infertility treatments as part of PHC services.
Primary care level facilities in Papua New Guinea offer RMNCH services in the aid posts, sub health centers, health centers and district hospitals. The services are provided by community health workers, nursing officers and the midwives. The services can be provided by any of the occupations at any one time. Kenya on the other hand offers primary care services in the community health units outside the health facilities, in the dispensaries and in the health centres. The types of care offered at the different levels of primary care differ based on the service and the cadres offering them at each level.
The services can be provided by any of the occupations at any one time. Sultanate of Oman offers the primary health care services in the health centres and polyclinics, where services are provided by nurses and the general medical practitioners simultaneously. Bangladesh offers primary care health services in the community clinics, union sub centers, union health family welfare clinics and upazila health complex. The services are offered by health care providers, midwives, family welfare visitors, sub assistant community medical officers, staff nurses and medical officers. Ghana offers PHC services in community-based health planning and services (CHPS) compound, health centres and district hospitals. The services are delivered by community health nurses and midwives. Appendix (Tables 9, 10, 11, 12 and 13) shows RMNCH services, the times taken and the specific occupations offering them in the five countries. Further, the health occupations that provide the RMNCH services at PHC level were mapped according to the International Standard Classification of Occupations (ISCO-08)  as shown in Table 3.
We also examined how the health workers in the primary health care facilities distributed their health service activities time for RMNCH services. This enables the understanding of how these services are offered along the continuum of care from pre-natal through pregnancy, childbirth, post-natal and to early childhood. Priority interventions show the linkages and help in contextualising services provided in the consecutive life stages. Bangladesh, Ghana and Kenya record first ANC and follow up ANC separately with different times while Oman and Papua New Guinea do not differentiate the first ANC and the follow up ANC.
Using the total time dedicated to RMNCH activities as a denominator, we analyzed the time distribution across the RMNCH services. It revealed that a substantial proportion of the health workers time is spent on offering ANC and PNC services. At the PHC level, 50% of health workers time in Bangladesh, 42% in Papua New Guinea, 40% in the Sultanate of Oman, 36% in Kenya and 33% of the health workers time in Ghana is spent on ANC and PNC interventions. Further details on baby wellness, immunizations and family planning show that countries dedicated different times for the services. Ghana primary health care workers dedicated over 50% of their time to offer family planning services, while Kenyan primary health care workers dedicated 30% of their time to the same family planning, Bangladesh and Papua New Guinea primary health care workers both dedicated 20% of their time to family planning and only 15% was dedicated for family planning by the primary health care workers of the Sultanate of Oman. Papua New Guinea health workers spent an average of 35% for child health in immunizations and baby wellness, Kenya and Bangladesh spent 30% while Ghana and Sultanate of Oman spent 15% each for immunizations and baby wellness interventions. Only Sultanate of Oman provided infertility treatment at primary care level facilities and the health care workers dedicated 21% of their time to offer this service. None of the countries had similar time distribution for RMNCH services as shown in Fig. 1.
This his paper focused on a review and synthesis of selected health services related to RMNCH health interventions offered at the primary health care facilities of five countries. The activities take up most of a health worker’s time and have annual statistics regularly collected on them. Also considered in the review was the amount of time necessary for a well-trained skilled and motivated worker to perform these activities to their professional standards in the given circumstances of the countries . These variables helped in assessing the length of professional time for each of the occupations required to execute the RMNCH services.
Increasingly, across the globe, there is emphasis on establishing integrated service delivery through the continuum of care’. This system provides a range of health services in the various life stages including the adolescence, pre-natal, childbirth and postnatal period, childhood and through reproductive age so that care can evolve with the patient over time [21, 22]. Integrated services enhance access to services by ensuring coordinated care. For example a mother can schedule to have her family planning visits together with immunizations at the same time thus benefits are extended to the patients, caregivers and the larger health care systems.
In addition, services should be available at all levels including in homes and communities, through outpatient services and hospitals with ‘inpatient’ facilities to clearly connect the services to referral-level services. This approach is based on the sound principle that the health of an individual across the life stages is interlinked . The time health workers take to offer services is also an important factor. Although the principle of equal access to medically justified treatment with the standard times has been promoted by official health policies and guidelines, practices do not completely meet these targets. Good health of both the mother and the newborn are directly linked and any health intervention to prevent mortality applies to both the mother and newborn. There is evidence that simple and timely intervention like antenatal care, skilled childbirth, post-natal and new-born care can bring about positive impact on RMNCH services [6, 24].
Examining case studies makes it evident that human resources planning based on workload components and activity standards can and does play an essential role in the primary health care system. The practices, policies and relevant competencies of health occupations are imperative in developing and improving reproductive, maternal, newborn and child health services. The implication is that further research and studies must be conducted in order to determine additional health service interventions that can be beneficial to the health sector.
First, RMNCH services remain poorly documented in electronic databases; it may therefore be possible that, despite the very careful and extensive selection and expert consultations, some relevant RMNCH interventions were not identified. Second, there are no widely accepted models of primary health care delivery models and health occupations. Though we have carefully specified the inclusion criteria, there is a need for a clear taxonomy of primary health care occupations. Nevertheless, key data were available and rigorous methods have been applied throughout, including the risk of bias assessments and evaluation of the quality of the evidence.
This comparative multi-country case study on workload components and activity standards for RMNCH serves as a configuration for health teams. This study concludes that the health care service models, health services delivery contexts, health care worker teams, workload components and their sub activities vary from one country to another. It will be therefore inappropriate to develop activity standards to be adopted or adapted from one country to another despite the seeming similarity in the defined workload components and their related sub components for RMNCH at the PHC level. Evidence based workforce planning therefore requires that each country develops its own workload components, its sub activities and activity standards aligned to their own local contexts.
