Sustainability, or “the extent to which an evidence-based intervention is able to deliver its intended benefits after external support from a donor agency is terminated” , should be the end goal of most donor-funded global health interventions. Sustainability planning aims to facilitate the transition and may employ a specific transition plan for that purpose, leading to the formal handover of a donor-funded programme to a local partner. Although sustainability planning has been promoted in global health programmes, and, more recently, incorporated into strategies to strengthen countries’ self-reliance , it has historically received limited resources because funding is focused on programme planning, implementation, monitoring, and evaluation. Nonetheless, the sustainability of positive health outcomes continues to gain importance in the current global context, with reduced funding for development programmes and increasing recognition of the need for processes to transition them to country ownership [3-5]. In addition, a drive towards universal health coverage means that capitalizing on integrated health services and decreasing redundant or parallel efforts in health programming is paramount.
Integrated community case management (iCCM) of childhood pneumonia, diarrhoea, and malaria has increased access to treatment for children under five years of age, and notably reduced mortality in areas of limited health services . A hallmark feature of iCCM programmes is the use of trained community health workers (CHWs) that can deliver diagnostic and treatment services for multiple childhood illnesses [7,8]. As a health care service delivery strategy, iCCM includes the training, supplying, and supervising of CHWs to treat children for diarrhoea using oral rehydration salts (ORS), to treat children for suspected pneumonia using oral antibiotics, and to administer rapid diagnostic tests and treat children for malaria using artemisinin-based combination therapy .
Given the focus of the Sustainable Development Goals (SDG), particularly SDG 3.2 (ending preventable deaths of newborns and children under 5 years of age) and SDG 3.8 (achieving universal health coverage), more countries are scaling-up iCCM to strategically increase access to essential health services. Understanding how iCCM has been implemented is therefore imperative to sustain and scale achievements in iCCM service delivery [10,11]. Questions around feasibility of sustainability in the long-term persist, particularly in light of donor-funded programmes [11-16]. Except for a few countries, iCCM programmes have been mainly funded by donors, putting the sustainability of such programmes at risk due to reliance on external funding.
Substantial research on the critical elements required for sustainable health programmes already exist, in particular, for HIV/AIDS programmes. The US President’s Emergency Plan for AIDS Relief (known as PEPFAR) 3.0 presided over a shift in HIV/AIDS programming to a more sustainable and country-owned approach, with a focus on countries and key populations with high disease burden . This focus on transition has provided examples of implementation of key elements required for sustainability, some of which are generalisable to other health areas, including: leadership and management capacity, political and economic factors, supportive policies, alternative funding sources, integration of programmes into the wider health system, institutionalization of processes, the strength of procurement and supply chain management, and identification of staffing and training needs, amongst others . Analyses have indicated that current spending on AIDS is not sufficient to sustain achievements, necessitating a strategic approach to programme and sustainability planning, so that low-income countries can reliably manage HIV programming .
Lessons from transitioning large-scale HIV/AIDS programmes parallel those derived from iCCM programme research. George et al.  emphasises the importance of iCCM policy analyses to identify and understand factors that pose challenges to achieving and sustaining scale, and others advocate for including local perspectives and evidence [19,20]. Government support and political will, stable funding of financial support, organisational and contextual factors, community support, commodities and supplies, and human resources including management capacity are also identified as critical elements of sustaining the health gains made through iCCM [12-14,21-23]. Like sustained health behavior change, programme sustainability is multidimensional, with both internal and external factors affecting it .
WHO’s Rapid Access Expansion (RAcE) Programme increased access to treatment for malaria, pneumonia, and diarrhoeal disease among children under five years of age through iCCM in five countries: the Democratic Republic of the Congo (DRC), Malawi, Mozambique, Niger, and Nigeria, as part of WHO’s Global Malaria Programme, with funding from Global Affairs Canada (Table 1). The RAcE programme also aimed to strengthen the capacity of national and local health authorities to manage and implement iCCM activities in all five countries. WHO recognized that a systematic and inclusive process to plan for the sustainability and transition of iCCM interventions was crucial to sustain the achievements in reducing child mortality in each of the RAcE project areas. WHO contracted experts in 2016 to facilitate a planning process by providing technical assistance to national, state, and local health authorities, communities, and other key stakeholders to develop a sustainability strategy. The main documents produced included a roadmap consistent with national priorities and the many guidelines for the health system, particularly child and community health, and a plan to transition management and service delivery of RAcE activities to national structures. The purpose of this article is to describe the sustainability planning process for the iCCM programmes and its outputs, and to examine progress against the roadmap to transition iCCM programmes in RAcE countries.

This article describes a programme planning process and examines progress made against that plan; it is not research involving human subjects, so we did not seek ethics approval. We approached the challenge of sustaining iCCM programmes by incorporating recommended themes of adaptation and a learning health care system  in an established dynamic sustainability planning process . We utilised a sustainability framework focused on six components, to facilitate a series of defined steps to coordinate the local system of people and institutions managing, providing, and influencing iCCM services in each RAcE programme area. This awareness of health system dynamics and interactions within a local system, where people and institutions naturally and strategically adapt to one another and change in capacity in a nonlinear fashion , underscores the importance of coordinating and collaborating with both national and local stakeholders.
Creating a sustainability framework for iCCM services
We drafted a sustainability framework to guide the planning, identifying themes and components incorporated in previous work with sustainability planning for maternal and child health programmes  and literature pertinent to iCCM programmes . The framework draft depicted six components, each comprising several elements. We presented the draft framework for discussion and validation to key RAcE project stakeholders (MOH, WHO, and NGO grantee staff) from the DRC, Malawi, Mozambique, Niger, and Abia and Niger States, Nigeria at the June 2016 inception meeting held in Abuja, Nigeria and subsequently refined the framework with feedback obtained at that meeting. We validated this framework with a larger group of stakeholders at workshops in each RAcE project area to create the final guiding framework for this sustainability planning initiative (Figure 1 and Appendix S1 in Online Supplementary Document).
We organized and facilitated sustainability planning workshops in each country with support from NGO grantees and WHO country offices. The three-day workshops had two objectives: to draft a roadmap for institutionalising iCCM, and to draft a transition plan in support of the roadmap to guide activities during the last year of RAcE support. During the workshops, key stakeholders, including MOH, WHO, and NGO grantee staff, along with other influential government, academic, donor, and civil society actors, created a statement describing the national vision for the iCCM programme (Appendix S2 in Online Supplementary Document). To create a vision statement, facilitators prompted participants to form small groups and create a narrative or picture of what a sustained iCCM programme would look like two years after the end of the RAcE project, taking on the role of a post-project evaluation team conducting an evaluation on how well aspects of the iCCM programme had been sustained. Small groups then presented their visions to the full group. Facilitators and participants mapped commonalities and discussed differences to reach consensus on the vision statement.
At the workshop, participants also validated the sustainability framework and included points to contextualize it to their particular setting in the roadmap and transition plans (sample workshop agenda in Appendix S3 in Online Supplementary Document). For this purpose, roadmaps were conceptualized as documenting both the current state of sustainability of the iCCM programmes and the milestones or benchmarks that, if achieved, would enhance sustainability. We created a roadmap template to guide participants’ discussions and work (Appendix S4 in Online Supplementary Document). Participants worked in small groups to identify issues, next steps, and timelines related to one or more components of the sustainability framework. These groups also drafted detailed transition plans to guide activities during the next year. Transition plans typically aligned with the first year of activities articulated in the roadmaps. In each programme area, state or national authorities approved the roadmaps.
Monitoring progress towards sustainability
We monitored the status of activities through progress update meetings with NGO grantees and related reports for three months for all project areas except Mozambique, where the project ended after the roadmap was completed, and then analyzed progress by synthesizing information from key informants and monitoring reports. We produced a synthesis report for each RAcE project area and co-facilitated dissemination meetings for participants to discuss the findings presented in the reports and to update the roadmaps.
For this analysis, we compared priorities identified in roadmaps across RAcE project sites and examined progress against roadmaps during the monitoring period and recommendations based on roadmap priorities that were unaddressed or needed further attention.
This section presents the main outputs of the processes undertaken: the sustainability framework for iCCM, vision statements, and roadmap priorities; and, synthesizes information about progress made against the roadmaps and future priorities for all RAcE sites. We present the planning process for Niger State, Nigeria as a detailed case study in Appendix S5 in Online Supplementary Document.
Sustainability framework for iCCM
The validated sustainability framework for iCCM comprises six components: health outcomes, high-quality health services and data, MOH capacity, civil society capacity, community capacity, and the political and ecological environment. Each component is supported by several elements (Figure 1). Health outcomes, at the center, are affected by interactions among high-quality health services and data, MOH capacity, community capacity and civil society capacity, which operate within a political and ecological environment that directly affects the iCCM programme and its sustainability but is only indirectly affected by it. The same framework guided planning in all of the project areas except Malawi, where the team proposed minor adaptations (Appendix S1 in Online Supplementary Document). Stakeholders in Malawi wanted to encircle the health outcomes with high-quality health services, supported by MOH capacity, civil society capacity, and community capacity. In addition, they included culture and communication in the political and ecological environment. The components and elements in the sustainability framework guided the planning reflected in the roadmaps.
Comparative analysis of roadmap priorities
We compared roadmap priorities (Table 2) and identified a few patterns among the prioritised elements in different project areas. Overall, every project area identified priorities related to policy and coordination of external stakeholders including funders; supply chain management; service delivery and referral system; and communication and social mobilisation, indicating that these factors have persisted despite programme maturity, and are also of concern to new programmes. Four programme areas identified internal planning and coordination; supervision; and, quality assurance for services as priorities. Countries with either a mature iCCM programme (Malawi) or mature CHW programme (Mozambique) did not identify general human resource issues, including training, capacity building and recruitment, as a priority, which emerged as a priority for the other programme locations. However, stakeholders in Malawi identified specific human resource issues pertaining to CHW deployment, and internal planning and coordination remains a challenge in Mozambique. Data management, including data use, was identified as a priority for the newer iCCM programmes, including the programmes in Niger, and Abia and Niger States in Nigeria.

Synthesis of progress and recommendations
Table 3 reports the vision statements and summarizes progress in RAcE project sites and recommendations for sustaining iCCM programmes. Each vision statement articulates a “big picture” goal for child health. The team in Malawi, which works with the most mature iCCM programme among RAcE project sites, outlined the most specific vision, calling out critical elements of iCCM programmes including personnel, supplies, and system supports.

Community engagement, supply management, data processes, government leadership, and CHW remuneration or retention were recurrent themes in most project areas during the transition period and some examples are presented here. Social mobilisation activities were conducted with RAcE support in Niger State, but some Village Development Committees had yet to be established in Abia State and social mobilisation was carried out by a local NGO (Gracodev). In most areas, the RAcE project was still procuring and distributing supplies, although discussions with governments about taking over those tasks were under way. Some trainings in data collection and management had occurred, eg, in Niger State and in Malawi. In addition, health zones in DRC had tools to compile data. The Provincial MOH took over M&E activities in DRC and local government worked with the RAcE project to jointly mentor and coach CHWs in Niger State. However, a lack of district interest was noted in Malawi, and the national strategic plan for iCCM had not yet been adopted in Niger. Community support for CHWs was deemed important, but progress was uneven. In Niger State, some communities provided support through food and other incentives, while others did not. Community leadership did not move beyond verbal commitment in Niger. The RAcE project was still retaining ReCos in DRC. Although we could not monitor the transition in Mozambique due to the project ending, persistent threats to the APE programme in Mozambique have been noted, including donor-dependent funding for monthly incentives  and heavy workloads. In addition, stakeholders noted that MISAU has a limited capacity to manage, implement, and finance the iCCM programme.
Two recommendations for all project areas are to use the iCCM roadmap to guide future investments and efforts, and to update it regularly as the programmes mature. Table 3 lists other recommendations addressing the common themes of community engagement, supply management, data processes, government leadership, and CHW remuneration or retention. Specifically, identifying champions and creating structures within the government to support iCCM programmes emerged as an important step in the immediate term to sustain the programmes. For example, given that iCCM was recently introduced in Abia State, focused advocacy efforts will be needed to ensure state ownership of the programme. Other strategies for engaging communities, improving data management, strengthening supply chains and supporting CHWs were also made.
In this paper we reported the process and outputs of a sustainability planning initiative for RAcE project sites. We also compared roadmap priorities, progress against roadmaps, and recommendations among the project sites. We found that every project area identified priorities related to policy and coordination of external stakeholders including funders; supply chain management; service delivery and referral system; and communication and social mobilisation. Moreover, community engagement, supply management, data processes, government leadership, and CHW remuneration or retention were recurrent themes in most project areas during the transition period. Identifying champions and creating structures within the government to support iCCM programmes emerged as an important step in the immediate term to sustain the programmes.
Sustaining iCCM programmes can be crucial to sustaining improvements in child and community health outcomes in some settings, and is an emerging priority [8,11]. The framework we created incorporates the elements of a health system approach , while expanding service planning and delivery to include civil society partners and a broader consideration of the political and ecological environmental context. Identifying programme priorities and documenting them in a roadmap, along with deliberately planning for transition from an external implementer to a national system, may facilitate positive sustainability efforts and outcomes. These processes incorporate policy history and context, which have been deemed critical for national iCCM programme support , through the engagement of stakeholders at multiple levels and through multiple sectors. Although this approach should be formally tested, we have shown that adapting and using it in different contexts creates an inclusive and expansive (ie, multi-level and multisectoral) dialogue about systemic factors that influence the sustainability of a health service or programme.
The process of designing roadmaps included working with practical tools and guidance that facilitated thinking about specific issues related to implementing iCCM. This process included identifying critical challenges, involving multiple stakeholders, thinking across multiple sectors beyond the health system, establishing timeframes for achieving benchmarks, and building on established country or state strengths. Technical Working Groups (TWGs) formed at the conclusion of each workshop continued to advise roadmap updates in programme areas. Ideally, this group will be able to continually update the roadmap so that it is contextually current and responsive, a critical feature of working toward sustainability within a changing environment . The feasibility of full transition from externally guided implementation to autonomous implementation in each project setting was variable, and in most countries it was evident that limited resources would not allow for the same level of iCCM services without donor funding. All RAcE projects were able to transition some roles, responsibilities, and activities for iCCM to the MOH and other local partners. Common aspects of programme implementation that were transitioned included monitoring and evaluation activities, supervision, training, and data management. It should be noted that, as LMIC economies grow, they may be able to assume a greater role in the administration of programmes currently funded by donors, although poorer countries are more susceptible to political corruption and violent conflict which undermine progress . In addition, the fluctuations of global markets create uncertainty about sustained capacity to implement health and other programmes. Further, climate change has a disproportionate impact on LMIC .
Although the transition experienced some successes, a longer transition period would have been beneficial, meaning that planning for sustainability at the beginning of a project may have afforded a stronger “end game” for transition. Ideally, a sustainability framework should be used during programme planning to ensure that a programme is designed to be sustained . This approach offers the advantage of providing an opportunity to build the capacity of national and local stakeholders in a measured and deliberate manner. In addition, convening key stakeholders to establish a TWG early in programme implementation would enable that group to exercise an important role in coordination and planning throughout programme implementation.
Finally, this process seeks to address practical realities to sustaining iCCM programmes through country-specific dialogue and solutions. While there is ongoing global dialogue about the best ways to finance iCCM programmes  and retain CHWs , countries and donors continue to grapple with how to ensure smooth transitions from external to internal funding and management. These discussions within countries naturally require multi-level and multisectoral conversations, which this sustainability planning process supports. But donors, too, could participate in sustainability planning dialogues and serve countries better by aligning investments with roadmap priorities, to ultimately move programmes closer to sustainment.
There are some limitations to this analysis. It was both comparative and summative; it was infeasible to analyze every roadmap element in detail. This approach necessarily tends toward superficiality; however, it is useful to look across programmes to review the emerging priorities for iCCM sustainability. Although limited conclusions can be drawn from the comparative analysis, and priorities and challenges are specific to context, the process and tools we described could be adapted for other settings, and should be formally tested. As iCCM grows as a health care delivery strategy in many countries, engaging stakeholders in processes to create TWGs and produce roadmaps could assist programme implementers with identifying and addressing the challenges that their programmes face, and ultimately sustaining health gains. In addition, our definition of sustainability is limited here to programme sustainability. The framework omits some relevant factors such as antimicrobial resistance and does not specify elements such as climate change, which is becoming increasingly important for health service planning. Further, future studies may consider power dynamics among stakeholders to elucidate relevant factors affecting sustainability [46,47], and macro-level factors that can counteract system strengthening efforts, such as competing priorities and the hierarchical structure of personnel roles in a system . Global reviews of iCCM implementation will continue to inform sustainability planning by identifying emerging factors to incorporate in relevant frameworks .
In conclusion, the expectation for the sustainability of a health service is that the local system that produces health (inclusive of policy makers, programme implementers and service providers, and community members) is robust and resilient enough to maintain health coverage and outcome gains while adapting to changing conditions. Embarking on a process to plan for the sustainability of iCCM services optimizes investments in the programme by ensuring that life-saving curative services will continue to be available to children in hard-to-reach areas when funding and other conditions change. Areas where work remains to increase the likelihood of iCCM programme sustainability included political leadership; supply chain management; human resource capacity, supervision and retention; data management; and, community engagement. Future investments in iCCM programmes should assist country teams to address these issues.
