Revitalising primary health care (PHC) and the need to reach MDG targets requires developing countries to adapt current evidence about effective health systems to their local context. Timor-Leste in one of the world’s newest developing nations, with high maternal and child mortality rates, malaria, TB and malnutrition. Mountainous terrain and lack of transport pose serious challenges for accessing health services and implementing preventive health strategies.
We conducted a non-systematic review of the literature and identified six components of an effective PHC system. These were mapped onto three countries’ PHC systems and present a case study from Timor-Leste’s Servisu Integrado du Saude Comunidade (SISCa) focussing on MDGs. Some of the challenges of implementing these into practice are shown through locally collected health system data.
An effective PHC system comprises 1) Strong leadership and government in human rights for health; 2) Prioritisation of cost-effective interventions; 3) Establishing an interactive and integrated culture of community engagement; 4) Providing an integrated continuum of care at the community level; 5) Supporting skilled and equipped health workers at all levels of the health system; 6) Creating a systems cycle of feedback using data to inform health care. The implementation case study from Timor-Leste (population 1 million) shows that in its third year, limited country-wide data had been collected and the SISCa program provided over half a million health interactions at the village level. However, only half of SISCa clinics were functional across the country. Attendances included not only pregnant women and children, but also adults and older community members. Development partners have played a key role in supporting this implementation process.
The SISCa program is a PHC model implementing current best practice to reach remote communities in a new developing country. Despite limited resources, village level healthcare and engagement can be achieved but takes a long-term commitment and partnership.
The thirty-year anniversary of the 1978 Alma-Ata declaration called for the revitalisation of Primary Health Care as “a set of guiding values for health development, a set of principles for the organisation of health services, and a range of approaches for addressing priority health needs and the fundamental determinants of health” . The World Health Report in that same year was careful to make the distinction between the service-delivery-focused ‘primary care’ and ‘primary health care’ which more broadly mobilises societies to transform health systems driven by values such as equity, solidarity and participation .
Whilst the Alma-Ata Declaration did not see the achievement of health for all by 2000, the rebirth of many of these ideals within the broader cross-sectoral development agenda in the Millennium Development Goals (MDGs) has continued a level of commitment, arguably at a greater level. However, as the world sits a few years away from the MDG target date of 2015, there has been patchy achievement, particularly in the health-related goals MDG 4,5 and 6 worldwide  and the focus in many countries continues to be on vertically-driven, selective programs and donor-driven agendas.
Current thinking advocates for integration, a continuum of care approach and closer linkage of health to development . This has been accompanied by a growing body of knowledge about what has worked and what has not. Encouragingly, the evidence supports a number of the principles and components which were part of the original Alma-Ata Declaration but the challenges of implementation remain. In this paper we summarise the evidence-base for six core principles and components of effective primary health care and provide a case example from Timor-Leste of how they have been implemented.
We conducted a non-systematic review of the literature using key words primary healthcare, health outcome and systematic review in Medline, the Cochrane Database of Systematic Reviews, DARE and Health Technology Assessment. To try and capture reports in the grey literature we also search Google and key international development agency websites. We used a series of articles published in the Lancet for the 30-year anniversary of the Alma Ata Declaration as a core set of papers and hand-searched the bibliographies of these and related articles. Articles were included if they provided some level of systematic review of evidence relating to PHC in low or middle-income countries. This case study does not include any experimental research, nor any research carried out on humans or animals and as such did not require ethics committee approval.
Six components of an effective primary health care system
1. Strong leadership, partnership and government in human rights for health
The World Health Organisation’s constitution states that “the enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being”. The protection of human rights for health can only be achieved through inter-sectoral action requiring a ‘whole of government’ commitment . Social development and good governance are linked to strong comprehensive primary health care systems . These require leadership and commitment to appropriate strategies and funding by national governments. A review showed that of the fourteen countries furthest along the path of progress towards a comprehensive and equitable primary health care system, almost all have benefited from strong government commitment to an agreed national essential health package with defined priorities and links to the not-for-profit sector, non-government organisations and other service providers in the system .
2. Prioritisation of cost-effective interventions
There is a growing body of evidence for cost-effective interventions which can be implemented at the primary care level in developing countries. A pragmatic coverage of these interventions in the maternal, neonatal and child health area, would prevent 20-30% of maternal deaths, 20-21% neonatal deaths and 29-40% of post-neonatal deaths . If 99% coverage of this package is achieved, their model predicts that this would increase to 67.3% of maternal deaths, 45% neonatal and 79% of post-neonatal deaths averted.

-*Active case identification of TB in households and treatment with DOTs
3. Establishing an interactive and integrated culture of community engagement
Community engagement goes to the heart of the principles of Alma Ata and yet, has often been the component of primary health care that has been most neglected. Within this construct of ‘community engagement’ it’s important to distinguish between ‘participation', ‘mobilisation’ and ‘empowerment’. Participation can either be active or passive involvement whereas ‘mobilisation’ usually refers to communities responding to directives from health professionals to improve their health. More recently, there has been an important return to ‘empowerment’ strategies that have health workers acting as facilitators with communities to identify strategies and make decisions that impact on the ‘process’ of health improvement [7, 8].
Community-mediated interventions can improve health outcomes although many of these have been top-down strategies through training community health workers and less often through bottom-up or interactive models of community engagement. A Cochrane review of eighteen trials showed that community-based interventions did not show any reduction in maternal mortality (RR 0.77; 95% CI 0.59 to 1.02) but did significantly reduce maternal morbidity (RR 0.75; 95% CI 0.61 to 0.92), neonatal mortality (RR 0.76; 95% CI 0.68 to 0.84), stillbirths (RR 0.84; 95% CI 0.74 to 0.97), and perinatal mortality (RR 0.80; 95% CI 0.71 to 0.91). It also increased the referrals to health facilities for pregnancy-related complications by 40% (RR 1.40; 95% CI 1.19 to 1.65), and improved the rates of early breastfeeding by 94% (RR 1.94; 95% CI 1.56 to 2.42) . A separate review by Bhutta et al. found the pooled effect of community-based interventions resulted in a 31% reduction in neonatal mortality (RR = 0.69, 95%CI 0.61-0.77), a 29% reduction in peri-natal mortality (RR = 0.71, 95% CI 0.61-0.84) and 29% reduction in maternal morbidity (RR = 0.71, 95% CI 0.53-0.94) .
Unfortunately, early evidence for the effectiveness of community empowerment strategies was largely replaced by an exclusive focus on evidence-based cost-effective interventions whose effects could be more easily quantified in the 1990s and early 2000’s . The research and global health community needs to embrace new research methodologies which measure the processes of decision-making and empowerment in communities. Such strategies have the potential to not only improve health literacy, but also to address local cultural issues and health beliefs as well as geographic and health challenges specific to that community . Studies which develop and evaluate complex interventions to facilitate informed decision-making for communities in developing country settings may help to improve understanding of this in the future .
4. Providing an integrated continuum of care at the community level
Several important analyses have recently looked at what has worked and what has not. Rohde et al. took life expectancy against gross national income (GNI) and identified that the top thirty low and middle income countries could be categorised as having one of three types of primary health care systems - selective primary health care, primary health care in transition, or comprehensive primary health care . Selective primary health care systems focussed on specific interventions delivered vertically but at the community level. Comprehensive primary health care systems on the other hand, have a strong focus on community health workers, good referral systems to the district level, equitable access to services for all, including the poorest communities and those geographically isolated and the use of data for decision-making. These countries were more likely to have more skilled birth attendances, lower maternal and child mortality, higher contraceptive prevalence, better immunisation coverage and inter-sectoral outcomes such as access to safe drinking water, school attendance by girls and adult literacy levels . They are also associated with improved effectiveness, equity and efficiency .
Comprehensive primary health care systems should be best placed to implement a ‘continuum of care’ across the lifecycle. Maternal and child health advocates have recently described how this might look in practice by aiming for universal coverage with integrated essential care packages across the maternal and child health lifecycle and alongside other strategies such as malaria, TB, water and sanitation programs . Whilst the association between better health and comprehensive primary health care is encouraging, a separate review comparing the effect of integrated services against fragmented services was inconclusive and unable to find enough experimental evidence to infer causality .
5. Supporting skilled and equipped health workers at all levels of the health system
There are many challenges in retaining and supporting health workers which can threaten emerging primary health care systems. Efficient systems and good governance must ensure appropriate financing and distribution of essential medications and equipment in a sustainable system. Effective and clear referral pathways must be available for serious clinical cases.
However, developed world experience shows that simply having staff and systems in place does not necessarily translate evidence into practice. Cost-effective interventions exist and a number of international protocols have been translated and adapted for country-specific contexts. However, the real challenge lies with the effective implementation of such interventions, guidelines and protocols. A review of four randomised and six non-randomised controlled studies in developing countries looking at the effect of education and training on health professional behaviour. These showed an improvement in compliance with guidelines but the effect was not sustained. A range of educational formats, including locally adapted and facilitated sessions were used but none were compared head-to-head. There is insufficient evidence to assess the effectiveness of educational outreach, local opinion leaders, use of mass media, and reminders. Educational materials alone are unlikely to influence change . Creating effective ways of keeping health professionals up-to-date in developing countries is an important item for the future research agenda.
6. Creating a systems cycle of feedback using data to inform health care
Feedback with data to communities and to health professionals is likely to improve the implementation of effective strategies into practice . In fact, this is the only strategy that has been shown to have such an effect in developing countries through one randomised and three non-randomised controlled studies (all hospital-based). Several of the studies highlighted that sustainability can be limited by organisational barriers. One suggested framework for the implementation of an integrated primary health care strategy puts data collection and feedback as a vital part of an effective health system. This requires governments to support their district managers to implement, monitor and evaluate their health services and to disseminate the results. At the central and district health sector level, the use of data in the process of planning and monitoring policy and service delivery is challenging but has the potential to focus limited resources on identified gaps and to highlight areas of success. At the service provision and community level it can also be used for audit and feedback for quality improvement for health providers and for empowerment of communities .
Implementing the core components of PHC revitalisation in practice: A case study from Timor-Leste
Timor-Leste (formerly known as East Timor) lies on the eastern side of the island of Timor, with the western half being part of Indonesia. It is located to the north of Australia and west of Papua. The total population is approximately one million, with the majority of people living in remote villages (sucos and aldeias) in rugged mountain terrain, often cut-off by landslides and flooded rivers during the wet season. From the 16th century onwards, Timor-Leste was a Portuguese colony, occupied briefly by Japan in World War II and defended by Australian and Dutch forces. There was a brief period of semi-independence in mid-November 1975 but Timor-Leste was invaded by Indonesia on 7 December 1975 and occupied until the UN took over in 1999 and subsequently became a formally independent nation on May 20, 2002 after UN-supervised elections in 2001. The stability of Timor-Leste in the first few years of democracy was fragile with a serious conflict breaking out in 2006 and many people being internally displaced. Only since 2007 has there been a period of stability and economic progress. Timor-Leste has oil and gas reserves managed in trust by the World Bank which provide a regulated income source for the nation.
Structure of the overall health system and health-seeking behaviour
Most effort has been on the establishment of core infrastructure, human resource planning and placement across the health system. There are currently 2.2 nurses per 1,000 population and 0.1 doctors per 1,000 population . The medical workforce was instantly supplied in 2004 by the Cuban government through a bilateral agreement supplying several hundred Cuban doctors to Timor-Leste and the training of one thousand Timorese doctors, initially in Cuba and now at the National University of Timor-Leste (UNTL). These Timorese graduates are now starting to work within the Timorese health system. International technical advisors in the Ministry of Health are gradually being phased out and local policy development is exemplified by the recent development of the new National Health Strategy of Timorese Policymakers.
The 2003 Timor-Leste Demographic Health Survey reported that one-quarter of the population reported that it took more than two hours to reach their usual health provider and 86% walked to their nearest health facility. By 2008 a national study of health-seeking behaviour reiterated that participants still described long and difficult journeys to seek assistance for illness, using locally available traditional remedies as an alternative with limited capacity to engage in preventive health behaviours . Although the Ministry of Health established one community health centre (CHC) with moderate in-patient facilities in each of the thirteen districts, and one CHC with no in-patient capacity in each sub-district, there was not the capacity to reach one health post in every village cluster (suco) with only 198 of the planned 442 established. One of the key reasons for developing the SISCa program was to address this shortfall at the community level, improving uptake of preventive healthcare and access to basic medical services.

There are six components (tables) within the SISCa structure.
Table one: Registration
Family registration (Registo Saude Familiar): Each suco should have a register of all households to be used to monitor key health indicators nationally and locally. The data include names and ages of all household members, number of pregnant women, chronic diseases, children with malnutrition, immunisations, TB cases, recent births and any deaths in the household. It forms the denominator for the ‘library of registers’ which are an important functional component of the SISCa program (described later in this article). Once the family register is completed it can be updated every month by the local health team who should be aware of new pregnancies, births, illnesses and deaths.
Table two: Nutrition assistance and child health promotion
Malnutrition is a significant problem in Timor-Leste with almost half of children under five years stunted, underweight or malnourished. Mothers are encouraged to bring all children under-five to be weighed and have their mid-upper-arm circumference measured. Counselling and referral for under-nutrition is integrated with this service. Exclusive breastfeeding and good maternal nutrition is encouraged. Children are offered Vitamin A and de-worming treatment every six months and childhood immunisations are administered. Potential agricultural solutions to food insecurity should be explored and mothers taught how to cook healthy meals for young children using local foods through meetings with the local leaders, cooking demonstrations and posters or flyers with pictures of healthy food options. Food supplements and supplies can be distributed to families at risk. Inter-sectoral collaboration with agriculture can be facilitated through the SISCa program’s community engagement and surveillance.
Timor-Leste has seen infant mortality fall from 68 per 1,000 live births in the period 1999–2003  to 44 per 1,000 live births in 2004–2009 . The MDG4 target for under-five mortality by 2015 is 53 per 1,000 live births and the 2010 Demographic Health Survey (DHS) reported it is currently 64 per 1,000 live births. There has also been an almost threefold increase in the number of children 12–23 months considered by the WHO to be “fully immunized”, from 18 percent in 2003 to 53 percent in 2009  and a recent report by the UNDP goes so far as to suggest that these improvements could be attributable, at least in part, to the SISCa program . Ministry of Health routinely collected data in 2010 suggests this immunisation coverage may have risen further to around 66 per cent . Routinely collected data also shows that the proportion of children under five being weighed has increased from 14.1 per cent in 2008 to 21.2 per cent in 2010 . The SISCa program is providing a platform for a more assertive effort to address this problem.
Table three: Maternal health and family spacing
The MDG5 target for reduced maternal mortality may not be achieved by 2015 with a maternal mortality ratio of 557 per 100,000  and the Ministry of Health reporting 450 per 100,000 live births . Midwives are in attendance if possible, and a register is maintained of all pregnancies. The first half of the patient held record book (LISIO) is completed for pregnant mothers and the second half is for the infant and child. A proactive approach is taken to identifying pregnant women within the community and encouraging them to attend the SISCa for antenatal care. The health team also actively seeks out women who may have delivered recently and require a postnatal check which may involve home visits. A range of family spacing options are available alongside health promotion videos and other resources which seek to facilitate informed choice in family spacing.
The proportion of women having at least one antenatal care increased from 61 percent in 2003 to 86 percent in 2009 and there has been an increase in skilled birth attendance from 18.4 per cent in 2003 to 29.9 per cent [20, 24]. The proportion of women receiving postnatal care has also increased from 14.6 per cent to 32 per cent in the same period, fertility rates have fallen from 7.8 to 5.5 and contraceptive coverage has increased from 10 per cent to 22.3 percent.
Table four: Hygiene, sanitation and malaria prevention
Health promotion staff, community health workers (PSFs), NGOs and others work with communities on personal hygiene, bed-net promotion, vector control and water and sanitation strategies. Hand-washing demonstrations and bed-net distribution to all households of pregnant women and children under five are important responsibilities of this table. Community health workers are also asked to complete a household survey (called Kubasa) on water, sanitation and hygiene prior to the SISCa. As with the other surveys and registers these form a ‘library’ or virtual database for each community.
Access to clean drinking water and adequate sanitation remains a major problem for Timor-Leste. The number of households using an improved water source only increased from 53 per cent to 63 per cent between 2003 and 2009 and household with inadequate sanitation reduced from 70 per cent to 57.1 per cent [20, 24]. The number of children under five sleeping under a bed-net has increased from 21.2 per cent in 2007 to 45.5% in 2009 .
Table five: Ambulatory primary care
A doctor or nurse is available to assess sick children and adults and can prescribe basic treatments or refer to secondary care services as required. Treatment of childhood respiratory disease, gastroenteritis, implementation of IMCI, case detection of malaria and TB including spot sputum collection and rapid-tests for malaria and the commencement of treatment or referral can occur. Active case detection of TB and malaria has seen the national case detection rates increase from 76 per cent in 2005 to 84 per cent and cohort cure rates rise from 61 per cent in 2005 to 73 per cent in 2008 . Ministry of Health data also suggests that malaria incidence has reduced with 132.9 cases per 1,000 in 2008 and 104.2 per 1,000 in 2010 .
Table six: Health promotion activities
Activities may include showing films, using flipcharts, group discussions or one-to-one counselling on issues that are relevant to the community (eg good child nutrition, malaria prevention, management of gastroenteritis in children, birth spacing methods, promoting birth at health facilities etc.).
SISCA Functional elements (A ‘library’ of registers for each community, Health care and delivery Audit and feedback for quality improvement)
The collection of registers for each community provides a rich dataset to inform health planning and services. Timor-Leste has poor or non-existent internet coverage in most districts, necessitating manual book registers for the moment. It is hoped that eventually this ‘library of registers’ will become electronic linking peripheral centres with each other the central facilities.
SISCa participation rates and evaluations can be fed back to health workers and communities affording an opportunity to change and improve service quality and respond to community needs. For example, local teams may identify poor child nutrition rates as a significant local issue allowing discussion about local solutions and ongoing monitoring of the impact. These functional elements have been amongst the most challenging to implement in a low tech environment with limited staff and community workers with lower levels if numeracy and literacy. It will take time to instil a culture of audit and feedback and to empower communities and local health teams in this way.
SISCa coverage and impact on health-seeking behaviour
Implementing the six components of effective primary health care
During the first few years of implementation of the SISCa program, some of the components of effective primary health care have been easier to achieve than others. Strong leadership and the inclusion of health as a human right in the country’s constitution have been fundamental in getting the program started and sustained. The SISCa program has remained as a core component in the new 20 year National Strategic Development Plan. The framework of SISCa allows for the prioritisation of many of the cost-effective interventions listed in Table 1, although not everything on this list is part of national protocols and, like most countries, there are substantial variations in the implementation of these. Engagement with communities has been reflected in the attendance rates shown in Figure 4 but the role and sustainability of community volunteers continues to need strengthening. Integrated healthcare is at the core of the SISCa program and has been more widely achieved than other components through the structural components of SISCa. The health workforce in Timor-Leste continues to expand and up-skill with strengthened referral pathways and supply chains being identified as a priority in the new strategic plan. Data systems and feedback cycles will likely be the most challenging component of the system to implement (Figure 3 and 4).
This paper has identified six core components of an effective PHC revitalisation. It has described how Timor-Leste has extended their primary health care system to integrate basic health service package delivery with active health promotion in community outreach. Although it is not possible to infer causality, the current improvements in health service utilisation, immunisation coverage and reduction in TB and malaria are encouraging and serve to illustrate how the SISCa concept aims to reach remote mountainous communities with targeted and effective interventions. The recently published UN Human Development Report for Timor shows the country is on track for many of the health MDGs with the need for a more concerted effort in measles vaccine coverage, maternal mortality, HIV/AIDS education and malaria control. Strengthening the current system will hopefully help to achieve these targets which will be a major achievement for one of the world’s youngest independent nations.
