Introduction: Healthcare provider payment reform is a key element of strategic purchasing to improve health system efficiency, equity, and quality. Although such reforms are well documented in high-income countries, evidence in low- and middle-income countries—particularly in sub-Saharan Africa—remains limited and fragmented. This scoping review aimed to identify, map, and systematize recent literature on provider payment reform for strategic purchasing and the factors influencing these reforms in 21 African Commonwealth countries.

Methods: The review followed the scoping review methodological guidelines of Peters et al. and was reported using the PRISMA-ScR checklist. Studies were retrieved from scientific databases and supplemented with gray literature. Factors influencing the reforms were analysed using a health policy framework covering context, content, process, and actors.

Results: Thirty-five full-text publications were included (29 empirical studies, four technical reports/policy briefs, and two reviews). The evidence spans eight countries, with six focusing on performance-based financing (PBF). Reforms often added new payment methods to existing ones (62.85%, n = 22/35), replaced existing methods (typically fee-for-service (FFS) with capitation in primary care (28.57%, n = 10/35)), or adopted mixed methods (37.14%, n = 13/35), with blending FFS and capitation being the most common. Multiple factors influenced different reform dimensions. Political inattention and inadequate policy, legal, and regulatory frameworks hindered the reform context. Reform content depended on clear core elements such as performance indicators, guidelines, tariffs, financial rewards, and provider autonomy. Factors such as a lack of reform piloting, chronic underfunding, fragmented funding flows, and inadequate monitoring and evaluation mechanisms hindered the reform process. The actor dimension was impacted by a lack of a holistic approach to stakeholders and limited stakeholder capacity to implement reforms.

Discussion: Current evidence for implementing provider payment reforms remains limited—concentrated in a few countries and often focused on specific reform types or evaluations from a single perspective. Future studies could focus on more comprehensive reform evaluations, incorporating multistakeholder perspectives and links with other elements of strategic purchasing.

1 Introduction

African leaders have demonstrated a strong commitment to advancing Universal Health Coverage (UHC), as reflected in key policy documents such as the Africa Health Strategy (2007–2015, extended to 2016–2030) and the Addis Ababa Call to Action on UHC in 2019 (1). These documents highlight the continent’s collective efforts to ensure equitable access to quality healthcare services for all citizens. Despite this widespread support, numerous challenges persist in pursuing UHC within resource-limited settings (2).

Strategic purchasing is recognized as a crucial health financing policy approach aimed at optimizing the use of limited resources to progress toward UHC (2, 3). This approach directs funds to priority populations, interventions, and services on the basis of evidence and health needs. Strategic purchasers in healthcare, such as the Ministry of Health, Social Health Insurance Fund, or local authorities, make deliberate decisions on the basis of five key areas: (1) coverage—determining for whom healthcare services should be purchased; (2) benefit package—deciding which services to purchase; (3) contracting—selecting providers; (4) quality—ensuring the quality of services; and (5) provider payment—determining the payment methods and prices for providers (4).

Previous studies have assessed the progress of various aspects of strategic purchasing in some African countries purchasing, including benefit design for improving access to priority services (e.g., high-value services such as reproductive and family planning; maternal, neonatal, and child health services) and stakeholder contracting arrangements (58). However, evidence on provider payment reforms in low- and middle-income countries (LMICs)—particularly in sub-Saharan Africa—remains limited, fragmented, and largely descriptive (9). Many existing studies focus on specific schemes such as performance-based financing (PBF), often within individual country contexts (1013). Systematic analyses that explore broader patterns and influencing factors across LMICs are rare (9, 14).

In contrast, evidence from high-income countries (HICs) shows that reforming healthcare provider payment schemes is a popular policy tool used to improve efficiency, quality, accountability, and overall health system performance (1519). Payment schemes are designed to influence healthcare providers’ behaviors, thereby playing a crucial role in strategic health purchasing. Common provider payment methods include: fee-for-service (FFS), where providers are paid per individual service delivered; capitation, which pays providers a fixed amount per patient over a set period regardless of service use; and performance-based financing (PBF), which links payments to the achievement of specific quality or service indicators. Each method offers distinct incentives and trade-offs—FFS can encourage an oversupply of care, capitation incentivizes efficiency but risks underprovision, while PBF emphasizes results but may increase administrative complexity (15, 20). Nevertheless, implementing such reforms successfully is challenging and often influenced by a mix of diverse barriers and facilitators (1719).

This review aimed to identify, map, and systematize recent literature (published within the last decade) on provider payment reform for strategic purchasing and the factors influencing these reforms in 21 African Commonwealth countries (Botswana, Cameroon, Gabon, Gambia, Ghana, Kenya, Eswatini, Lesotho, Malawi, Mauritius, Mozambique, Namibia, Nigeria, Rwanda, Seychelles, Sierra Leone, South Africa, Togo, Uganda, Tanzania, and Zambia). On the basis of general objectives of the scoping method (21), we examined the breadth of existing evidence, identified potential research gaps, and formulated implications for future studies.

2 Methods

The study followed the scoping review methodological guidelines of Peters and colleagues (21, 22), which included five steps: defining review questions, identifying relevant literature, selecting evidence, extracting evidence, and analyzing data. The results were reported via the PRISMA-ScR checklist (23), and the study protocol was registered with the Open Science Framework (24).

2.1 Defining research questions

The specific questions guiding the review were as follows:

1. What type of evidence is available? (study country, publication year, study type, study objective).

2. What type of payment method was analyzed (type of method, type of change)

3. What type of healthcare providers were involved (e.g., primary care vs. hospital)?

4. What factors (obstacles and facilitators) influenced the reform?

2.2 Identifying relevant literature

Three scientific databases—PubMed, Scopus, and Web of Science—were searched for empirical studies. The search strategy was iteratively developed and conducted using multiple synonyms of “healthcare provider” AND “payment” AND “country” in titles and abstracts. Complementary searches included Google and gray literature on relevant organization websites, such as the Strategic Purchasing Africa Resource Centre (SPARC), the WHO via WHO African Region, the World Bank, Responsive and Resilient Health Systems (RESYST), and Health Finance and Governance (HFG) country publications. The reference lists of the included publications were manually searched for additional studies. Details of the search strategy and records for each data source are provided in Supplementary Tables S1–S6. The searches were conducted between June and July 2023.

2.3 Selecting evidence

The publications were selected in two stages: screening abstracts and evaluating full texts on the basis of predefined inclusion and exclusion criteria (Supplementary Table S7). Studies were included if they: (1) focused on provider payments within strategic purchasing; (2) were peer-reviewed empirical studies, policy briefs, theoretical papers, technical reports, books/chapters, or theses; (3) focused on an African Commonwealth country; (4) were published between 2013 and 2023; and (5) were available in English. Studies were excluded if they: (1) did not focus on healthcare provider payment within strategic purchasing (e.g., focused on social insurance schemes, community financing, cost recovery, medication payments, or informal caregiving); (2) were not full-text publications (e.g., conference abstracts); (3) focused on non- African Commonwealth countries; (4) were published before 2013; or (5) were in other languages.

Two independent researchers (CN and KDJ) conducted the title and abstract screening phase, achieving an agreement level above 80%. The full-text evaluation was performed by one researcher (CN) and reviewed by KDJ. Mendeley and Rayyan software were used for data management.

2.4 Data extraction

Data extraction tables were created using MS Excel and were tailored to specific research questions. A single researcher (CN) conducted the extraction, which was reviewed by another researcher (KDJ) and further by all coauthors during the draft and final manuscript review stages.

2.5 Data analysis and reporting

The study employed inductive thematic analysis to analyze qualitative data, which was then coded for quantitative summaries and tabulated. The paper types were classified into four categories: empirical studies (original, based on primary data, published in peer-reviewed journals), discussion/policy papers (published in peer-reviewed journals), literature reviews (published in peer-reviewed journals), and technical reports/policy briefs (e.g., policy briefs published by advocacy organizations). For payment methods reforms, the OECD classification (15) was used to code whether the reform modified an existing payment method, introduced an additional method, or replaced it with a new method.

Factors influencing reforms were deductively classified using the health policy framework (2527), which consists of CONTEXT (systemic factors, e.g., political, economic, and cultural influences), CONTENT (detailed elements of a reform), PROCESS (creation, communication, implementation, and evaluation of the reform), and ACTORS (participants in policymaking: individuals, organizations, groups, and the government).

3 Results

3.1 Search results

The database searches yielded 3,030 records, with 1,603 duplicates. After screening 1,427 titles and abstracts, 65 full texts were reviewed, and 30 met the inclusion criteria. Most studies (n = 19) were excluded because they did not focus on healthcare providers. Four articles from organizations and one from reference lists were included, totaling 35 publications for the final analysis. Figure 1 shows the PRISMA flowchart, and Table 1 lists all included studies by country and relevant details aligned with the study questions.

3.2 Overview of publications

The 35 studies included (1113, 2859) were from eight countries. Of these, 29 were empirical studies, four were technical reports/policy briefs (32, 48, 53, 59), and two were reviews (40, 54). One review was a scoping review mapping progress in strategic health purchasing in Cameroon (54), and the other was a narrative review assessing health purchasing reforms’ effects on equity, access, quality of care, and financial protection in Kenya (40). Empirical studies primarily evaluated specific experiences with payment reforms, notably pay-for-performance [P4P, n = 12/35, also known as results-based financing (RBF) or performance-based financing (PBF)] and capitation (n = 10/35). Studies utilized qualitative (n = 16/35), quantitative (n = 9/35), or mixed methods (n = 4/35) to assess these reforms. Reform assessment often emphasized specific stakeholders’ perspectives, including providers’ experiences, opinions, and preferences (31.42%, n = 11/35). Examples include Ghana’s capitation (30, 31, 56, 57), Kenya’s capitation and fee-for-service (FFS) (37), and PBF in Mozambique (12) and Rwanda (45). Some evaluations took a system perspective (22.85%, n = 8/35), assessing payment methods’ effectiveness in achieving broader healthcare system objectives [for example, the evaluation of PBF strategies to improve maternal health service access and utilization in Cameroon (11)]. In some cases, evaluations aimed to draw lessons from healthcare provider payment reforms for the entire health system. An example is the evaluation of capitation in primary healthcare (PHC) in Ghana, which aimed to inform a nationwide rollout (55). Evaluations could also compare achievements before and after payment reform, as observed in Tanzania’s study on technical efficiency before and after the P4P scheme (47).

3.3 Payment methods reforms

Reforms in many countries frequently centered on adding new payment methods to existing ones (62.85%, n = 22/35), with P4P being the most commonly adopted method to bolster the strategic purchasing of specific curative, preventive, and promotional services (Table 1). Many reforms concentrated particularly on maternal and child health. Primary prevention efforts prioritized vaccinations such as childhood immunizations (e.g., measles) and maternal tetanus vaccinations during prenatal care, as seen in Rwanda (46), Tanzania (13), and Cameroon (11). Prevention measures aimed at controlling infectious diseases such as HIV and tuberculosis were also noted in Mozambique (12), Cameroon (54), and Rwanda (44, 45). In 37.14% (13/35) of the studies, countries added methods with the intention of using mixed methods to pay providers, predominantly combining FFS and capitation. This approach was evident in countries such as Kenya (34, 3638), Uganda (50), Tanzania (49), and Nigeria (4143). Other reforms were implemented to completely replace existing payment methods, notably replacing FFS with capitation in PHC, prominently in Ghana (2832, 55, 56, 58, 59). Ghana introduced capitation in 2012 to contain costs, share financial risk, enhance competition, and improve efficiency and claims processing after previous methods such as FFS and diagnosis-related grouping (G-DRG) were ineffective in addressing these challenges (32, 55, 56).

3.4 Types of providers involved

Certain payment reforms targeted specific providers, such as replacing FFS with capitation in PHC. However, most reforms, such as PBF, were broadly applied across various provider categories, including PHCs, hospitals, and/or specialty care (11, 46, 48, 51, 54). Both public and nonpublic sectors were sometimes included, as seen in Kenya (37) and Tanzania (49), where capitation and FFS were applied to public, private, and charity providers, and in Cameroon (11, 48), for PBF.

3.5 Factors influencing payment reforms

In the surveyed countries, various interconnected factors impacted different reform dimensions (Table 1). The reform context was frequently shaped by political will, policies, legal frameworks, and governance structures for strategic purchasing practices. Political neglect often led to superficial endorsement of reforms without sustained commitment, resulting in inconsistent implementation (32, 42, 58). Inadequacies in legal and regulatory frameworks hindered the effective operationalization of reforms, resulting in implementation inefficiencies and gaps (13, 3436, 39, 50, 51, 54).

Reform content factors stemmed from essential elements such as guidelines, performance indicators, tariffs, financial incentives, and providers’ autonomy over finances. These were important to ensure clarity, consistency, and alignment with reform objectives. Guidelines guided reform implementors (32, 41, 43, 46, 4951). Unclear indicators hindered many reforms, but good examples were observed in countries like Rwanda (46), Cameroon (54), Ghana (32), Nigeria (41, 43), and Uganda (50, 51). Transparent tariffs provided fair incentives (33, 43, 48, 49), whereas financial autonomy allowed providers to use resources flexibly, responsively, and responsibly [e.g., PBF programs in Camerron (48, 54), Mozambique (12), and Tanzania (13)].

Several factors impacted the reform process dimension, with top barriers stemming from the absence of reform piloting, chronic underfunding, fragmented funding flows, and inadequate monitoring and evaluation mechanisms. Piloting reform helped identify implementation challenges and informed its redesign before a nationwide rollout [e.g., capitation in Ghana (55) and PBF programs in Rwanda (4446) and Tanzania (13, 47)]. Piloting proved essential for detecting and addressing potential issues early. Chronic underfunding crippled the ability to sustain long-term reform initiatives. Payment reform in various countries suffered heavy dependency on donor funds (13, 31, 32, 41, 43, 4752, 54, 56, 57, 59). Fragmented funding flows with often multiple payment systems further exacerbated these issues by creating inefficiencies and misallocations of resources (11, 36, 39, 40, 42, 43, 4749, 51, 54, 57). Inadequate monitoring and evaluation mechanisms led to a lack of accountability and transparency, impeding the ability to measure progress and make necessary adjustments (11, 34, 35, 3942, 48, 51, 54).

Finally, the reform actor dimension was frequently impacted by barriers associated with a lack of a holistic approach to stakeholders and inadequate stakeholder capacity to perform reform tasks. Reforms and involved stakeholders varied within and between countries. Frequent actors can generally be grouped into government, purchasers, healthcare providers (including provider groups), and the general public. Notably, in most reforms, the general public, such as citizens or patients and their associations, was commonly overlooked (12, 29, 3436, 41, 51, 53, 55).

4 Discussion

Evidence suggests that since 2013, only eight of the 21 African Commonwealth countries have implemented healthcare provider payment reforms. This underscores a scarcity consistent with previous findings in low-income economy countries (19). Countries typically add new payment methods to existing ones (usually P4P for different providers), replace FFS with capitation in PHC, or mix these two methods. This shift from FFS to capitation aims to contain costs, as FFS can lead to cost increases and service oversupply, jeopardizing the financial stability of purchasers (16). Capitation has been identified as a preferred approach for PHC financing in LMICs due to its potential to align incentives with population health goals (60). For instance, Thailand’s capitation-based system has helped expand comprehensive PHC coverage at the district level (60, 61). Capitation is known to promote efficiency (62), reduce costs (63, 64), generate attractive provider revenue (65), promote compliance with guidelines and policies (66), and improve provider performance and patient education (67). However, it can also affect care quality and quantity (65), may discourage providers from serving high-risk patients (68), and affect patient-provider relationships (68). Many countries have adopted mixed payment systems that combine FFS and capitation (34, 3643, 49, 50), a strategy supported by high-income country literature in PHC (16). Mixed payment models can offset the disadvantages of pure payment methods and make them attractive options for policymakers (16, 6973).

The factors influencing payment reforms in the surveyed countries are broadly consistent with those in the international literature (18, 19). Contextual factors such as political will and regulatory frameworks play crucial roles in most reforms, particularly when they coincide with other health policies and political priorities (19). We found that the success of a reform largely depended on its clarity and transparency in content elements such as performance indicators, payment rates and quality criteria as well as its potential to generate positive perceptions and interests among key stakeholders, particularly providers. Consistent with previous studies, deficiencies in these elements can lead to several problems, such as tensions between providers and reformers, which can stagnate reform efforts (19, 74). The reform process is often hindered by chronic underfunding, largely driven by donor influence in low-resource settings and further exacerbated by high fragmentation in financing and health service delivery systems, as consistently observed by previous researchers (19, 74). Conversely, piloting reforms is often considered a key process facilitator, helping countries identify implementation challenges and inform redesign before nationwide rollout. However, the selection of pilot sites must also consider political and contextual factors. In Ghana, for example, choosing a region associated with opposition political interests led to suspicion and resistance, illustrating how local dynamics can undermine the credibility of reform piloting (32, 58). Finally, we emphasize the importance of stakeholder engagement for successful reform implementation, but ensuring that stakeholders have sufficient capacity to carry out the assigned tasks is crucial. Many payment reforms were hindered by the lack of sufficient capacity of stakeholders (e.g., financial capacity, human resources, technical skills, and tools such as IT). An interesting approach is the technique observed in Ghana (32) of mapping the capacities of stakeholders and forming groups for those who are unable to implement reforms independently. Further research is needed to evaluate this practice and shed light on potential challenges and strengths or feasibility in other, particularly resource-limited, countries.

This study highlights important research gaps. In African Commonwealth countries, current evidence on provider payment reforms for strategic health purchasing is limited—not only because such reforms have been implemented in relatively few countries, but also because, where they do exist, the available evidence often focuses on specific types of reforms and/or presents evaluations from a single perspective. Our results help define indications for future studies. First, PBF is the most commonly implemented reform (studies were identified in six of the eight countries for which evidence was found). Previous studies have also shown that such outcome-based payment models have gained traction, but their scope is narrow and they focus on specific diseases or conditions (18, 75, 76). In particular, studies have reported mixed results concerning the long-term viability of P4P in similar settings (77, 78), and a review of PBF in LMICs concluded that no definitive conclusions could be drawn regarding the likely impact of PBF (79). Therefore, the effectiveness of these methods in the studied settings remains to be investigated. Second, it is worth noting that the majority of studies examining the impacts of capitation reforms focus on experiences in Ghana. While these insights are undoubtedly valuable, they may not provide a comprehensive understanding of how such payment reforms play out in other countries on the continent. Third, many of the reforms included are broad and target multiple providers at the same time. This approach often lacks the nuance needed to determine which methods are most effective for certain types of providers. Although some countries combine methods that can sometimes mitigate the unintended consequences of individual payment methods, previous research has suggested that certain methods may be more suitable for particular types of providers while proving ineffective for others (80). Examples include capitation for PHC plus FFS for priority interventions, FFS with P4P for episodic care, and DRGs with global budget (70). This practice of which methods should be blended for specific types of providers particularly needs to be investigated in the studied countries. Additionally, it is crucial to acknowledge the absence of experiences regarding other value-based payment methods, such as bundled payment methods, within the study settings. Bundled payments are crucial for effective care continuity, especially for chronic conditions (70). Future research should examine the potential of such payment initiatives in African settings and assess their feasibility. Additionally, the provider payment method defines the mechanism used to transfer funds from purchasers to providers (20) and is just one of five interrelated elements of the strategic purchasing framework (4, 5). Future studies could be aimed at a more comprehensive reform evaluation, e.g., from a multistakeholder perspective and/or in interconnection/relation with other elements of strategic purchasing. Finally, the issue of factors influencing payment reform success can be investigated via targeted original research, with a focus on developing policy recommendations for best practices to overcome specific barriers.

This review has several strengths. It is the first study to systematically synthesize provider payment reforms in African Commonwealth countries using a structured health policy framework. The search strategy included both peer-reviewed and gray literature. However, certain limitations should be noted. The review included only English-language literature. Although this is justified given that English is the common official language in Commonwealth countries, relevant local-language sources may have been excluded. Additionally, the study relied on publicly available published evidence, which may omit unpublished reform documentation or evaluations. Finally, in line with the scoping review methodology (22), we did not assess the quality of the included studies.

5 Conclusion

This study highlights a major research gap in healthcare provider payment reforms in African Commonwealth countries. The evidence shows a trend toward supplementing traditional methods with new ones, such as P4P, replacing FFS with capitation, or mixed models. Unlike high-income countries, which prioritize bundled payments for chronic diseases, African countries’ reforms often focus on specific diseases such as HIV or maternal health. Success factors in Africa are similar to those in high-income countries, but unique challenges include fragmented funding and heavy reliance on donors.
