Abstract
Global Framework: The Role of the UN and WHO
The United Nations (UN) and the World Health Organisation (WHO) have long emphasised the central role of equitable and accessible healthcare in promoting social development and human well-being. Both institutions advocate that governments, regardless of their income level, should strive to ensure the provision of timely, comprehensive, and high-quality health services to all citizens within the limits of their available resources (World Health Organisation, 2010; United Nations, 2015). These recommendations are grounded in the broader principles of Universal Health Coverage (UHC), which requires that all individuals have access to essential healthcare services without facing financial hardship. For countries in the Global South, such as Tanzania, these goals are particularly challenging because of complex financing mechanisms, structural inequalities, and resource constraints that undermine the sustainability and equity of healthcare provision.
Tanzania’s Health Financing Landscape
In the Tanzanian context, healthcare financing is characterised by a highly fragmented system that draws upon multiple, often poorly coordinated, sources of revenue. Funding streams include public and private insurance schemes, allocations from government budgets, donor contributions, and significant levels of out-of-pocket expenditure by households (Ministry of Health [MoH] et al., 2022; World Bank, 2021). Among these, out-of-pocket payments remain disproportionately high, accounting for nearly half of the country’s total healthcare financing. Such reliance on direct household contributions creates inequities in service access and contributes to financial vulnerability among patients, particularly those in rural and low-income settings.
Governmental allocations to the health sector, although essential, remain limited and insufficient to meet the growing healthcare needs of the population. Donor funds, although substantial, are typically earmarked for specific vertical programs, such as HIV/AIDS, malaria, and maternal and child health, which restricts flexibility and leaves significant gaps in overall health system financing (Makene et al., 2020). This imbalance perpetuates dependence on unstable external resources, making it challenging to build a resilient, nationally driven system.
Limitations of Post-Pay Models
Another structural issue arises from the country’s reliance on "post-pay" models of healthcare financing. In this system, payments to providers are made after services are delivered, generating significant financial uncertainty for healthcare facilities and practitioners. This arrangement inadvertently fosters perverse incentives for over-servicing, since providers may increase revenue through excessive diagnostic testing, over-prescription of medications, or the administration of unnecessary procedures (Mtei & Borghi, 2010; Kapologwe et al., 2022).
While such practices may benefit providers in the short term, they contribute to inefficiencies, resource wastage, and, ultimately, sub-optimal care for patients. Furthermore, patients bear the consequences of delayed or inadequate treatment, since scarce resources are misallocated toward unnecessary interventions rather than prioritised for essential, life-saving services.
Consequences for Access and Equity
The cumulative effect of these financing challenges is the persistent exclusion of a substantial proportion of Tanzania’s population from equitable access to quality healthcare. Financial barriers, inefficiencies in resource utilisation, and dependence on fragmented funding mechanisms combine to undermine progress toward Universal Health Coverage. Consequently, health outcomes remain uneven, with vulnerable populations experiencing the most significant deprivation (Borghi et al., 2013; United Republic of Tanzania [URT], 2023). Addressing these issues requires rethinking current models of health financing to reduce waste, minimise perverse incentives, and ensure that resources are allocated efficiently and equitably across the health system.
A Prepaid Alternative Model
In light of these challenges, this thesis explores an innovative alternative financing approach designed to enhance efficiency and equity in healthcare delivery. Specifically, the research investigates a prepaid model in which healthcare providers receive payment in advance for managing the care of a dedicated pool of randomly selected members. By distributing risk across a larger group and decoupling revenue from the volume of services delivered, this system aims to counteract the perverse incentives associated with post-pay models. Instead of rewarding the quantity of services, the prepaid approach encourages providers to focus on quality and efficiency, as their financial stability is tied to maintaining the health of their assigned population, rather than to service overutilization.
Methodological Approach
To assess the feasibility and potential effectiveness of this prepaid model in Tanzania, the study employed a structured consultation process with healthcare experts. A survey was conducted using the 1000minds Multi-Criteria DecisionMaking (MCDM) software, a tool designed to facilitate systematic evaluation of complex policy alternatives (Hansen & Ombler, 2009). Through this methodology, experts were asked to weigh different aspects of healthcare financing reform, including efficiency, equity, sustainability, and practicality of implementation. Fifty-five experts in the industry systematically analysed ten models of healthcare funding with the view to validating the superiority of the Comprehensive Global Capitation Model.
Key Findings and Implications
The results indicated a strong preference for prepaid systems over the current post-pay model, highlighting the perceived potential of this approach to address systemic inefficiencies, reduce waste, and improve healthcare outcomes. The findings of this research suggest that prepaid financing mechanisms may represent a viable pathway toward strengthening Tanzania’s health system and accelerating progress toward Universal Health Coverage. By addressing structural inefficiencies and realigning provider incentives, such reforms could help ensure that limited resources are used more effectively to improve health outcomes for the population.
Ultimately, the study underscores the importance of financing innovation as a cornerstone of health system reform and provides evidence to support the adoption of prepaid models as a strategic option for Tanzania’s pursuit of equitable, sustainable, and high-quality healthcare for all citizens.
