Achieving universal health coverage (UHC) involves distributing resources, especially human resources for health (HRH), to match population needs. This paper explores the policy lessons on HRH from four countries that have achieved sustained improvements in UHC: Brazil, Ghana, Mexico and Thailand. Its purpose is to inform global policy and financial commitments on HRH in support of UHC. The paper reports on country experiences using an analytical framework that examines effective coverage in relation to the availability, accessibility, acceptability and quality (AAAQ) of HRH. The AAAQ dimensions make it possible to perform tracing analysis on HRH policy actions since 1990 in the four countries of interest in relation to national trends in workforce numbers and population mortality rates. The findings inform key principles for evidence-based decision-making on HRH in support of UHC. First, HRH are critical to the expansion of health service coverage and the package of benefits; second, HRH strategies in each of the AAAQ dimensions collectively support achievements in effective coverage; and third, success is achieved through partnerships involving health and non-health actors. Facing the unprecedented health and development challenges that affect all countries and transforming HRH evidence into policy and practice must be at the heart of UHC and the post-2015 development agenda. It is a political imperative requiring national commitment and leadership to maximize the impact of available financial and human resources, and improve healthy life expectancy, with the recognition that improvements in health care are enabled by a health workforce that is fit for purpose.
This paper explores the HRH policy lessons from four countries – Brazil, Ghana, Mexico and Thailand (Table 1) – purposefully selected for having achieved sustained improvements in accelerating progress towards UHC since 1990.7 Part of their success lies in the policy focus on the health workforce to expand population coverage and the health benefits package. The paper reviews the available literature on the impact of HRH policy to identify the key actions and lessons that support accelerated progress towards UHC, with special attention to “effective coverage” and equity. By effective coverage we mean the proportion of people who have received satisfactory health services relative to the number needing such services.19,20 We focus on maternal and neonatal health – areas in which comparative data are widely available, given that measuring effective coverage of UHC within and across countries is feasible by establishing “tracers” or a subset of activities indicative of overall service quality and quantity.21 GDP, gross domestic product; GNI, gross national income; PPP, purchasing power parity; THE, total health expenditure; UHC, universal health coverage. a In PPP international dollars. b Population with health-care coverage and extent to which each country had attained UHC by the year indicated.

The paper focuses on these four dimensions as they apply specifically to the health workforce: availability (e.g. stock and production); accessibility (e.g. spatial, temporal and financial dimensions); acceptability (e.g. gender and sociocultural); and quality (e.g. competencies and regulation). Dimensions of universal health coverage (UHC) pertaining to human resources for health (HRH): effective coverage Adapted from The world health report (2010),4 UN Economic and Social Council (2000)22 and Tanahashi (1978).19 The framework shifts the focus beyond the current monitoring of access to and contact with a health worker – i.e. skilled attendance at birth, or density of health professionals per 1000 population – and turns the AAAQ dimensions of the workforce into the key determining factors of the quality of care,23 represented in Fig. 1 as the “effective coverage gap”. We apply the four workforce dimensions to guide a process-tracing analysis of HRH policy actions since 1990. Process tracing is an analytical tool for exploring causal mechanisms and contributory steps in the chain of events that collectively support a desired outcome.24–26 We collated historical data (Fig. 2, Fig. 3, Fig. 4 and Fig. 5) on national trends in the number of skilled birth attendants (midwives, nurses and physicians) employed in the public sector. Subject to data availability, the figures also show the rates for maternal mortality, under-five mortality and either infant or neonatal mortality. We have disaggregated the national policy and governance steps on HRH by their respective AAAQ dimensions (Table 2).27 The respective policies are captured chronologically to explore their linkages to national trends in the health workforce and maternal, neonatal and child health outcomes.

Note: Governments provide the political leadership, resolve and resources to effectively steward the education, deployment, management, financing and performance of a health workforce that equitably serves population needs, promotes the right to health and accelerates progress towards population-specific, comprehensive universal coverage. Partners, including consumers, civil society, the private sector, professional organizations, academia, and – in those countries where it is applicable – multilateral and bilateral agencies, support and facilitate the strengthening of the health workforce through mutual respect, participation, accountability, solidarity and financial subsidy, aligned with national needs and mechanisms. Health workers, in all cadres and sectors, should be responsive to population needs and enhance the quality of health systems and services. Governments, partners and health workers collectively and individually support a transnational, coordinated effort to strengthen the health workforce. They do so by ensuring the effective implementation of applicable international and regional conventions and resolutions on the right to health, the social determinants of health, universal coverage and the health workforce, using evidence, innovation and technologies to do so.

The complexity of decision-making and the confounders influencing improved health outcomes are not discussed here. Hence, while the paper explores causal mechanisms, it is beyond its scope to express causal conclusions. Instead, we use the case studies and wider published literature to identify what appears to have worked and where and draw examples of good practice from this evidence base. Since the adoption of its current constitution in 1988, Brazil has worked progressively to achieve UHC by setting up the Sistema Único de Saúde (SUS) [Unified Health System], an integrated health service system based on the provision of community care and improved access for underserved populations. The SUS revealed the need to expand the health workforce, both in terms of adding staff and rationalizing roles and responsibilities, especially in relation to developing new skills and building management capacity at the municipal level – the locus of health service delivery. The government implemented several steps to produce more staff, improve their training, enhance working conditions and strengthen management capacity. The first major effort in the 1980s was the Programa Larga Escala [Long-term Programme], designed to qualify staff who had not received formal training. In 1987, before the SUS was created, the Capacitação em Desenvolvimento de Recursos Humanos initiative was launched to build capacity in HRH training and management. This was followed in 2006 by the establishment of the Programa de Qualificação e Estruturação da Gestão do Trabalho e da Educação no SUS (ProgeSUS) [Programme of Qualification and Structuring of the Management of Work and Education in the Unified Health System], a programme for strengthening HRH and, more generally, health service management.28 Other programmes, such as the 2003 Programa de Incentivo a Mudanças Curriculares nos Cursos de Medicina (PROMED) and the 2009 Programa de Educação pelo Trabalho para a Saúde (PET-Saúde) [Programme of Incentives for Curricular Changes in Medical Schools], have sought to improve service acceptability and quality and to bridge the gaps between HRH availability and need in the area of primary care. The family health team model, based on a multidisciplinary team of health workers oriented towards primary care, entails a re-orientation of the values and practices of health professionals towards the community29 and improvements in population health and, indirectly, in labour supply.30 The successes of these HRH policies have been made possible by strong political commitment and a sustained policy focus. Through the implementation of these policies and programmes, between 1990 and 2009 Brazil managed to increase the number of health workers – nurses by 500% and physicians by 66% – well above the 31% in population growth. Between 2002 and 2012 the number of family health teams doubled – from 15 000 to 30 000 – and in 2013 access to basic health units reached 57% of the population (i.e. 108 million people).31 Over the same period neonatal mortality decreased from 26.8 to 9.7 per 1000 live births and under-five mortality from 58 to 15.6 per 1000 live births, respectively. A 1992 constitutional amendment to ensure the right to health enhanced the political and financial commitment to a supply-driven expansion of the health workforce in Ghana. In 1996 new regulation, accompanied by administrative decentralization and the definition of HRH staffing norms, paved the way for Ghana’s Patient’s Rights Charter of 2002. The improved availability and accessibility of health workers since the turn of the millennium enabled the development of the High-Impact Rapid Delivery strategy (2005), aimed at expanding the package of essential interventions for maternal and child health and extending population coverage. The Human Resources for Health Strategic Plan (2007–2011), which integrated the accessibility, acceptability and quality dimensions, was instituted to improve deployment and retention strategies, accreditation, regulation and licensing and continuous professional development for staff. In 1990–2009, Ghana witnessed a rapid increase in its supply of professional health workers: 185% more midwives, 260% more nurses and 1300% more physicians. Approximately 14 000 additional professional health workers were trained and employed, a number representing four times the increase in population growth (240% versus 59%) over the same period. In the case of physicians, the growth in each 5-year period is fairly uniform, but in the case of midwives and nurses such growth dropped sharply towards the end of the period (2005–2009). The reduction has since been corrected, however, with the addition of more workers in 2010–12. Achieving equity in access to and use of essential services continues to be challenging.32 A large share of national health expenditure – approximately 85% – is committed to health workforce salaries and incentives, but the steps taken in 1990–2009 have reduced workforce attrition, increased the capacity of health training institutions – Ghana is now one of the largest producers of physicians in sub-Saharan Africa – and improved the number and distribution of health workers. Policies and programmes have generated large increases in the health workforce,33 beginning with the 1995 Health Sector Reform (1995–2000), which established agreements with educational institutions for the training of human resources and increased the number of health workers nationwide.34 The coverage expansion programme (PAC) initiated in 1996 to address accessibility employed thousands of workers to support health activities in underserved areas. Staff remuneration was initially covered by loans from the Inter-American Development Bank, but the health ministry committed to paying wages in subsequent phases of the programme. In 2002 the PAC was integrated into the new Programa de Calidad, Equidad y Desarrollo en Salud (PROCEDES) [Programme for Quality, Equity and Development in Health].35,36 The Sistema de Protección Social en Salud (SPSS) [System for Social Protection in Health] and the Seguro Popular de Salud (SPS) [Popular Health Insurance] were created in 2003 to pursue the goal of UHC, with encouraging results across all AAAQ domains.37 The number of nurses and physicians increased over 1990–2009. More than 250 000 additional professionals were trained and the 80% increase in nurses and the 170% increase in physicians outstripped the population growth of 30%. In the same period, infant mortality and under-five mortality more than halved: from 32.6 to 14.6 per 1000 live births and from 41 to 17.8 per 1000 live births, respectively.38–41 Maternal mortality fluctuated over the period but was reduced by more than 50% overall, according to data from 2011.42 Attrition between education and employment is an important workforce problem that remains to be addressed. According to an analysis of the 2008 Encuesta Nacional de Ocupación y Empleo (ENOE) [National Survey of Occupation and Employment], 87% of physicians are employed, but of those who are, approximately 10% work outside the health sector. Thus, nearly one in every five physicians is not participating in the health labour market, a rate that requires further scrutiny in light of the growing private sector for medical education. In 1990, only 7% of medical students were in private schools, but by 2010 the proportion had risen to 20%. Of the 27 new medical schools established during this period, five are publicly funded and the other 22 are funded by private investments.43–45 Although the HRH policy and governance milestones of 1990–2009 were clearly influential in Thailand’s success, critical decisions were also made in the 1970s. Such decisions continue to exert an influence 40 years later.46,47 Policies on the provision and financing of health services are pro-poor.48 Primary health care at the district level was made possible through a comprehensive health workforce policy developed in 1995 that centred on retention and professional satisfaction to encourage rural deployment,49 as well as through policy revisions introduced in 1997 and 2005. Several policies adopted from 1994 to 2009, emphasizing continuous reflection and improvement, have aimed to improve quality: development and strengthening of professional councils, regulation over curriculum standards and quality of training institutes, worker licensing and re-licensing. The establishment of the Healthcare Accreditation Institute in 2009 has consolidated these quality efforts. Post-service training in advanced practice for nursing cadres, such as nurse practitioners, intensive care unit nurses and anaesthesiology nurses, plays a significant task shifting role. Policy has centred on strengthening local and district health systems as a strategy to translate policy into practice and improve equity. The attention to equity is particularly important. Although in 1991–2009 the overall increase in nurses (210%) and physicians (186%) outstripped population growth (13%), the accessibility dimension improved even more. For example, the ratio of nurses to people increased from 1:7.2 to 1:3.4 in 1991–2009. Regional variations in workforce deployment between the least affluent north-eastern region and affluent areas such as Bangkok have also been substantially reduced.
