BackgroundInequitable allocation of resources is a widespread probleminmany health systems.Globally, health needs are diverse and require significant financial, human and other resources. These resources are however limited in many countries [33], thereby creating a distributional dilemma for policy-makers. Although the problems posed by resource inadequacy cannot be underesti- mated, particularly in developing countries, there is a commonly held view that, within countries of similar socio-economic standing, it is not how much a country spends, but rather how it spends its resources that deter-mines the health status of its population [1]. Evidencefromboth developed and developing countries suggests that inappropriate allocation of resources contribute greatly to inequities in health. In Australia, for example, although indigenous people have a life expectancy of nearly 20 years shorter than non-indigenous Australians [2,3], Deeble and others found that total expen-ditures per person for health services for indigenous Australians are notmuch higher than the rest of the population; a ratio of merely 1.22:1 [4]. In South Africans,the poorer health status of black people compared to white South African is believed to be partly the result of the historic imbalances and inequities in the resource allocation system.McIntyre observed that over 60%of health care spending in South Africa at the end of the 20th century was in the private sector [40], the main beneficiaries of which were the minority white population. In Madagascar, Castro-Leal et al. [5] found that the poorest 20% of the population consumes 12% ofpublic spending on health compared to 30% share of the total enjoyed by the richest 20%.The need to address inequity in health has received increased attention in recent years [6].This has exposed the mechanisms for allocation of public sector health resources to greater scrutiny. Inmany countries, policy-makers have come under pressure to abandon historical funding models which were widely perceived as inequitable and to develop explicit alternatives that would redress inequities within and between geographic regions. One issue that remains unresolved in the quest for more equitable resource distribution however, is the appropriate principle or set of principles that should guide resource allocation in order to bridge the existing gaps in equity. One major reason for the little consensus among scholars on this issue results from the diverse ways in which the term ‘equity’ is interpreted.Whatever interpretation one might have, equity remains a value-laden word; choosing between different definitions of equity therefore necessarily involvesmaking value judgements [7].The common interpretations of equity include‘equal expenditure per capita’, ‘equal inputs percapita’, ‘equal access for equal needs’, ‘equal utilisation for equal needs’, and ‘equal health’ [8]. Each of these definitions has its own benefits and difficulties with regards to measurement and operationalisation.‘Equal health’, for example, has been widely criticisedas being unrealistic, given the many factors that determine health including variations in genetic background and longstanding disparities in access to thewide range of resources which contribute to determining health outcomes. While some authors have argued that the ultimate aim of all definitions of equity is equality of health [34], others have suggested other objectives such as equality of access or equal access for equal needs[9]. Access, however, is a multidimensional concept and extremely difficult to measure.Most industrialised nations have adopted the ‘equality of access’ interpre-tation in their efforts to achieve fairness in distributionof services and resources [10–12].Many needs-based models for resource allocationin recent decades were developed on the basis of the equality of access principle. The best documented example is the Resource Allocation Working Party’s (RAWP) model developed in England in 1976. The RAWP model sought to allocate National Health Service (NHS) funds between geographical areas to secure equal opportunity of access for equal needs [39]. Countries such asAustralia,NewZealand,Canada and South Africa have taken the lead from the RAWP approach and developed their own needs-based systems with a similar aim of improving equity. A needs-based model has been also tried in Zambia [13] while Uganda has implemented a pro-poor resource allocation reform similar to needs-based funding [14]. However, efforts to improve equity through needs-based funding have overwhelmingly focused on broader geographic equitysuch as inter-regional or provincial equity. Equity at sub-regional levels has been virtually ignored in many countries, creating a knowledge vacuumregarding how resources are re-distributed by regional authorities.This lack of attention to equity at sub-regional levels could have profound implications for reducing general inequities in health. 2. Resource allocation in Ghana .Ghana is located on thewest coast ofAfrica, bordering Togo to the east, Cote d’lvoire to the west, BurkinaFaso to the north and the Gulf of Guinea to the south. It is a low-income country with a gross national income (GNI) per capita ofUS$ 320 [42].Over 40%of the estimated 20.5 million population lives below the poverty line. The population structure is significantly youthful, with about 40% of the total inhabitants under the age of 15. Rural residents make up around 55% of thetotal population. The infantmortality rate was about 60 per 1000 in 2003 while the overall life expectancy at birth for 2002 was nearly 58 years. Public sector health expenditure constituted about 2.8% of gross domestic product (GDP) in 2001 [41]. For administrative purposes, Ghana is divided into 10 regions and 110 districts (Fig. 1). The government has in the past few years initiated a policy to create an additional 20–30 districts.Allocation of health resources between and within the regions and districts in Ghana has been less than equitable. Generally, regions in the Northern half the country are more deprived in terms of access to health care than those in the southern sector.The ratio GhanaHealth Service (GHS) doctors per population for example is 1:16,201 in the Greater Accra region compared to 1:66,071 in the Northern region [31]. Withinindividual regions, inequities are rife, often with communities in remote locations havingmuchmore limited access to district-based health care services. Bridging inequities in access to health care is therefore one of the main national health policy goals. This is enshrined inthe mission statement of the Ministry of Health which states that:“TheMinistry ofHealthwillwork in collaborationwith all partners in the health sector to ensure that every individual, household and community is adequately informed about health and has equitable access to high quality health and related interventions” [30].Allocation of resources within the health system is in principle, designed to achieve the equality of accessgoal through the reduction of inequities between andwithin geographic regions, including the removal of financial barriers to access to services for the mos vulnerable segments of the population. The resource allocation decision-making process is decentralised.The Ghana Health Service (GHS) uses a resource allocation formula to allocate resources to regions. At the beginning of the planning season, the GHS assigns budgetary ceilings to the 10 Regional Health Adminis-trations (RHAs) in the country.This amount is allocatedin block for all districts in the region. Each RHA uses its own region-specific resource allocation formula to re-distribute this lump sum among the districts under its jurisdiction. It is on the basis of these allocations(as determined by the RHAs) that districts plan andbudget their activities. Completed activity plans and budgetary estimates of districts are collated by the RHA and returned to the MOH/GHS headquarters for approval.Once approved, theMOHdisburses the fundsdirectly to the various districts through the RHA. The RHA at this stage cannot alter what has been disbursed to individual districts.More recently, to promote inter-regional equity, the MOH has resorted to ‘top-slicing’ the GHS budget to target the four regions noted as the most deprived in the Ghana Poverty Reduction Strat-egy (GPRS) document, namely; the Northern, Upper East, Upper West and Central region [31].The use of different resource allocation criteria by the 10 regionsmeans progress towards equitymay vary from one region to another depending on the commit-ment to promoting equity and the particular criteria and strategies employed. To date, there has not been a systematic investigation to assess the allocation of resources within regions and the extent to which equity objectives are advanced (or not) through this process.This study examines the intra-regional resource allocation systems in the Ashanti and Northern regions ofGhana in order to assess and compare progress towards equity in terms of redistribution of funds in favour of the most deprived districts.For the purposes of this study, the definition ofequity embodied in the MOH mission statement, that is, equality of access to high quality care and inter-ventions was adopted. Equitable resource allocation is defined here as allocation of equal or equivalent resources for equal needs. Because of the strong association between health status and socio-economic dis-advantage in Ghana, health needs were measured in terms of relative deprivation or disadvantage. Districts with high levels of deprivation were considered to bein greater need of resources. Resource is defined in this study largely in terms of financial resources for district-level services.
