Country-level governance of global health initiatives: an evaluation of immunization coordination mechanisms in five countries of Asia

Grundy, J. — Thu, 19 Nov 2009 04:34:19 PST

Background In recent years there have been innovations in immunization financing and new technologies, and the scaling up of investment by the Global Alliance for Vaccines and Immunization (GAVI) in the Asia region. The main mechanism for coordination of this global health initiative (GHI) investment is country-level ‘Inter-Agency Coordination Committees’ (ICCs).

Aim The aim of the evaluation was to determine the utility and future perspectives of stakeholders regarding the role of ICCs in improving immunization services in the Asian Region.

Methods A literature review, documentary analysis and semi-structured interviews (n = 65) were undertaken in five countries (India, Bangladesh, Nepal, Sri Lanka and Indonesia), with senior level members of Ministries of Health and the GAVI partnership.

Results The evaluation has identified that there have been significant changes recently in the strategic environment for immunization, including developments in new vaccines, increasing GAVI investment, trends towards health system integration and decentralization, and institutional development of the non-government sector. This evaluation found that ICCs are functioning well in relation to information sharing and GAVI application processes. However, they are performing less well in the areas of evaluation, strategic gap analysis and coordination of immunization technical co-operation.

Conclusions There are high levels of institutional and contextual complexity at country level that require a more focused global response by GAVI to the governance challenges of institutions and partners implementing GHIs at the country level. ICCs should be maintained and strengthened in the more pluralistic context of an ‘immunization coordination system’ that is represented by the wider health sector, regulatory authorities, and civil society and private sector interests. Managing through systems, rather than being over-reliant on committees, will broaden participation in implementation and, in doing so, expand the reach of immunization and maternal and child health care services in developing countries.

The rise and fall of supervision in a project designed to strengthen supervision of Integrated Management of Childhood Illness in Benin

Rowe, A. K, Onikpo, F., Lama, M., Deming, M. S — Wed, 18 Nov 2009 07:28:59 PST

Objective In developing countries, supervision is a widely recognized strategy for improving health worker performance; and anecdotally, maintaining regular, high-quality supervision is difficult. However, remarkably little research has explored in depth why supervision is so challenging.

Methods In the context of a trial to improve health worker adherence to Integrated Management of Childhood Illness (IMCI) guidelines and strengthen supervision in southeastern Benin, we used record reviews, focus group discussions, key informant interviews, and cross-sectional surveys to examine the supervision process.

Findings Initially, little IMCI supervision occurred. The frequency increased substantially after implementing a series of workshops, but then deteriorated. Quantitative and qualitative data revealed obstacles to supervision at multiple levels of the health system. Based on supervisors’ opinions, the main problems were: poor coordination; inadequate management skills and ineffective management teams; a lack of motivation; problems related to decentralization; health workers sometimes resisting IMCI implementation; and less priority given to IMCI supervision because of incentives for non-supervision activities, a lack of leadership, and an expectation of integrated supervision. To this list, based on our observations, we add: the increasing supervision workload, time required for non-supervision activities, project interventions not always being implemented as planned, and the loss of particularly effective supervisors. In terms of correctly completing steps of the supervision process, the quality of supervision was generally good.

Conclusions Managers should monitor supervision, understand the evolving influences on supervision, and use their resources and authority to both promote supervision and remove impediments to supervision. Support from leaders can be crucial, thus donors and politicians should help make supervision a true priority. As with front-line clinicians, supervisors are health workers who need support. We emphasize the importance of research to identify effective and affordable strategies for improving supervision frequency and quality. (ClinicalTrials.gov number NCT00510679.)

A medication-estimated health status measure for predicting primary care visits: the Long-Term Therapeutic Groups Index

Dhabali, A. A H, Awang, R. — Wed, 18 Nov 2009 07:28:58 PST

Background Managed care is one of the means advocated for health care reforms. The Malaysian government has proposed managed care for its citizens. In the Malaysian private health care sector, managed care is practised on a small scale with crude risk adjustment. The main determinant of an individual's health service utilization is their health status (HS). HS is used as a risk adjuster for capitation payment. Prescribed medications represent a useful source for HS estimation. We aimed to develop and validate a medication-based HS estimate and to incorporate it in the Andersen model of health service utilization. This is a preparatory step in studying the feasibility of developing a model for risk assessment in the Malaysian context.

Methods Data were collected retrospectively from an academic year from computerized databases in University Sains Malaysia (USM) about users of USM primary care services. A user is a USM health scheme beneficiary who made at least one visit in the academic year to USM-assigned primary care providers. Socio-demographic variables, enrolment period, medications prescribed and number of visits were also collected. Chronic illness medications and some non-chronic illness medications were used to calculate the Long-Term Therapeutic Groups Index (LTTGI) which is an estimate of the HS of users. Using a random 50% of users, weighted least square methods were used to develop a model that predicts a user's number of visits. The other 50% were used for validation.

Results Socio-demographic variables explained 15% of variability in number of primary care visits among users. Adding the LTTGI improved the explanatory power of the model to 36% (P < 0.001). A similar contribution of the LTTGI was noted in the validation.

Conclusions The Long-Term Therapeutic Groups Index was successfully developed. Variability in number of primary care visits can be predicted by LTTGI-based models.

Integration of targeted health interventions into health systems: a conceptual framework for analysis

Atun, R., de Jongh, T., Secci, F., Ohiri, K., Adeyi, O. — Mon, 16 Nov 2009 07:57:34 PST

The benefits of integrating programmes that emphasize specific interventions into health systems to improve health outcomes have been widely debated. This debate has been driven by narrow binary considerations of integrated (horizontal) versus non-integrated (vertical) programmes, and characterized by polarization of views with protagonists for and against integration arguing the relative merits of each approach. The presence of both integrated and non-integrated programmes in many countries suggests benefits to each approach.

While the terms ‘vertical’ and ‘integrated’ are widely used, they each describe a range of phenomena. In practice the dichotomy between vertical and horizontal is not rigid and the extent of verticality or integration varies between programmes. However, systematic analysis of the relative merits of integration in various contexts and for different interventions is complicated as there is no commonly accepted definition of ‘integration’—a term loosely used to describe a variety of organizational arrangements for a range of programmes in different settings.

We present an analytical framework which enables deconstruction of the term integration into multiple facets, each corresponding to a critical health system function.

Our conceptual framework builds on theoretical propositions and empirical research in innovation studies, and in particular adoption and diffusion of innovations within health systems, and builds on our own earlier empirical research. It brings together the critical elements that affect adoption, diffusion and assimilation of a health intervention, and in doing so enables systematic and holistic exploration of the extent to which different interventions are integrated in varied settings and the reasons for the variation. The conceptual framework and the analytical approach we propose are intended to facilitate analysis in evaluative and formative studies of—and policies on—integration, for use in systematically comparing and contrasting health interventions in a country or in different settings to generate meaningful evidence to inform policy.

Health care utilization in Ecuador: a multilevel analysis of socio-economic determinants and inequality issues

Lopez-Cevallos, D. F, Chi, C. — Mon, 16 Nov 2009 07:57:33 PST

This article examines socio-economic determinants and inequality of health care utilization in Ecuador. Despite health reform efforts in Latin America, drastic socio-economic inequalities persist across the region, including Ecuador. Almost a third of Ecuador's population lack regular access to health services, while more than two-thirds have no health insurance and insufficient resources to pay for health care services. Using Andersen's model of health care utilization behaviour, relevant variables were selected from the 2004 National Demographic and Maternal & Child Health Survey (ENDEMAIN) household survey. Four outcomes were assessed: use of preventive services, number of curative visits, hospitalization, and use of antiparasitic medicines. Adjusting for various predisposing, enabling and need factors, a significant negative relationship was found between household economic status (as measured by assets and consumption quintiles) and utilization of preventive and curative services. The same was true for use of antiparasitic medicines. Further, indigenous ethnicity was found to be a significant negative predictor of health care utilization, regardless of economic status. These socio-economic inequalities in the use of health care services suggest the need for health care reform in Ecuador to address these issues more systematically. It is necessary for public health authorities to move forward on a reform that will expand coverage, particularly to indigenous and low- and middle-income households

From public to private and back again: sustaining a high service-delivery level during transition of management authority: a Cambodia case study

Jacobs, B., Thome, J.-M., Overtoom, R., Sam, S. O., Indermuhle, L., Price, N. — Mon, 16 Nov 2009 07:57:32 PST

Contracting non-governmental organizations (NGOs) has been shown to increase health service delivery output considerably over relatively short time frames in low-income countries, especially when applying performance-related pay as a stimulus. A key concern is how to manage the transition back to government-operated systems while maintaining health service delivery output levels. In this paper we describe and analyse the transition from NGO-managed to government-managed health services over a 3-year period in a health district in Cambodia with a focus on the level of health service delivery. Data are derived from four sources, including cross-sectional surveys and health management and financial information systems. The transition was achieved by focusing on all the building blocks of the health care system and ensuring an acceptable financial remuneration for the staff members of contracted health facilities. The latter was attained through performance subsidies derived from financial commitment by the central government, and revenue from user fees. Performance management had a crucial role in the gradual handover of responsibilities. Not all responsibilities were handed back to government over the case study period—notably the development of performance indicators and targets and the performance monitoring.

Household surveillance of severe neonatal illness by community health workers in Mirzapur, Bangladesh: coverage and compliance with referral

Mon, 16 Nov 2009 07:57:31 PST

Background Effective and scalable community-based strategies are needed for identification and management of serious neonatal illness.

Methods As part of a community-based, cluster-randomized controlled trial of the impact of a package of maternal-neonatal health care, community health workers (CHWs) were trained to conduct household surveillance and to identify and refer sick newborns according to a clinical algorithm. Assessments of newborns by CHWs at home were linked to hospital-based assessments by physicians, and factors impacting referral, referral compliance and outcome were evaluated.

Results Seventy-three per cent (7310/10 006) of live-born neonates enrolled in the study were assessed by CHWs at least once; 54% were assessed within 2 days of birth, but only 15% were attended at delivery. Among assessments for which referral was recommended, compliance was verified in 54% (495/919). Referrals recommended to young neonates 0–6 days old were 30% less likely to be complied with compared to older neonates. Compliance was positively associated with having very severe disease and selected clinical signs, including respiratory rate ≥70/minute; weak, abnormal or absent cry; lethargic or less than normal movement; and feeding problem. Among 239 neonates who died, only 38% were assessed by a CHW before death.

Conclusions Despite rigorous programmatic effort, reaching neonates within the first 2 days after birth remained a challenge, and parental compliance with referral recommendation was limited, particularly among young neonates. To optimize potential impact, community postnatal surveillance must be coupled with skilled attendance at delivery, and/or a worker skilled in recognition of neonatal illness must be placed in close proximity to the community to allow for rapid case management to avert early deaths.

Willingness to pay for community-based health insurance in Nigeria: do economic status and place of residence matter?

Onwujekwe, O., Okereke, E., Onoka, C., Uzochukwu, B., Kirigia, J., Petu, A. — Mon, 26 Oct 2009 01:05:53 PDT

Objective We examine socio-economic status (SES) and geographic differences in willingness of respondents to pay for community-based health insurance (CBHI).

Methods The study took place in Anambra and Enugu states, south-east Nigeria. It involved a rural, an urban and a semi-urban community in each of the two states. A pre-tested interviewer-administered questionnaire was used to collect information from a total of 3070 households selected by simple random sampling. Contingent valuation was used to elicit willingness to pay (WTP) using the bidding game format. Data were examined for correlation between SES and geographic locations with WTP. Log ordinary least squares (OLS) was used to examine the construct validity of elicited WTP.

Results Generally, less than 40% of the respondents were willing to pay for CBHI membership for themselves or other household members. The proportions of people who were willing to pay were much lower in the rural communities, at less than 7%. The average that respondents were willing to pay as a monthly premium for themselves ranged from 250 Naira (US$1.7) in a rural community to 343 Naira (US$2.9) in an urban community. The higher the SES group, the higher the stated WTP amount. Similarly, the urbanites stated higher WTP compared with peri-urban and rural dwellers. Males and people with more education stated higher WTP values than females and those with less education. Log OLS also showed that previously paying out-of-pocket for health care was negatively related to WTP. Previously paying for health care using any health insurance mechanism was positively related to WTP.

Conclusion Economic status and place of residence amongst other factors matter in peoples’ WTP for CBHI membership. Consumer awareness has to be created about the benefits of CBHI, especially in rural areas, and the amount to be paid has to be augmented with other means of financing (e.g. government and/or donor subsidies) to ensure success and sustainability of CBHI schemes.

Contracting for health and curative care use in Afghanistan between 2004 and 2005

Thu, 22 Oct 2009 06:31:17 PDT

Afghanistan has used several approaches to contracting as part of its national strategy to increase access to basic health services. This study compares changes in the utilization of outpatient curative services from 2004 to 2005 between the different approaches for contracting-out services to non-governmental service providers, contracting-in technical assistance at public sector facilities, and public sector facilities that did not use contracting.

We find that both contracting-in and contracting-out approaches are associated with substantial double difference increases in service use from 2004 to 2005 compared with non-contracted facilities. The double difference increase in contracting-out facilities for outpatient visits is 29% (P < 0.01), while outpatient visits from female patients increased 41% (P < 0.01), use by the poorest quintile increased 68% (P < 0.01) and use by children aged under 5 years increased 27% (P < 0.05). Comparing the individual contracting-out approaches, we find similar increases in outpatient visits when contracts are managed directly by the Ministry of Public Health compared with when contracts are managed by an experienced international non-profit organization. Finally, contracting-in facilities show even larger increases in all the measures of utilization other than visits from children under 5.

Although there are minor differences in the results between contracting-out approaches, these differences cannot be attributed to a specific contracting-out approach because of factors limiting the comparability of the groups. It is nonetheless clear that the government was able to manage contracts effectively despite early concerns about their lack of experience, and that contracting has helped to improve utilization of basic health services.

Community health insurance in Gudalur, India, increases access to hospital care

Tue, 20 Oct 2009 08:20:25 PDT

Background To reduce the burden of out-of-pocket payments on households in India, the government has introduced community health insurance (CHI) as part of its National Rural Health Mission. Indian CHI schemes have been shown to provide financial protection and have the potential to improve quality of care, but do not seem to improve access. This study examines this dimension of CHI performance and explores conditions under which a CHI scheme can improve access to hospital care for the poor.

Methods We conducted a panel survey at the ACCORD-AMS-ASHWINI (AAA) CHI scheme in India. The AAA CHI scheme protects the poorest sections of society against hospitalization expenses. 297 insured and 248 matched uninsured households were observed by village volunteers on a weekly basis for 12 months. Any patient presenting with a ‘major ailment’ in these households was interviewed using a structured questionnaire. Outcomes measured were utilization of hospital services, cost of treatment and quality of treatment received.

Results The two cohorts were similar regarding demographic, social and economic parameters. More insured than uninsured households expressed trust in the CHI scheme organizers. Both groups had similar levels of minor ailments, but the insured had higher incidence of chronic and major ailments. Insured patients had a hospital admission rate 2.2 times higher than uninsured patients, independent of confounding factors. This higher rate among the insured was also found in children and those with pre-existing conditions. Vulnerable sections of the insured population—children, pregnant women, the poorest—had the highest admission rates. Most admissions, in both cohorts, took place in the ASHWINI hospital. Credible and trustworthy organizers, effective providers, low co-payments, and low indirect costs contributed to this result.

Conclusions A well-designed CHI scheme has the potential to improve access to hospital care, even for vulnerable sections of the community—the poorest, individuals with pre-existing conditions like diabetes and hypertension, and pregnant women.

Medicine prices in urban Mozambique: a public health and economic study of pharmaceutical markets and price determinants in low-income settings

Russo, G., McPake, B. — Tue, 20 Oct 2009 08:20:23 PDT

It has been suggested that medicines are unaffordable in low-income countries and that world manufacturing and trade policies are responsible for high prices. This research investigates medicine prices in urban Mozambique with the objective of understanding how prices are formed and with what public health implications. The study adopts an economic framework and uses a combination of quantitative and qualitative methods to analyse local pharmaceutical prices and markets. The research findings suggest that: (a) local mark-ups are responsible for up to two-thirds of drugs’ final prices in private pharmacies; (b) statutory profit and cost ceilings are applied unevenly, due to lack of government control and collusion among suppliers; and (c) the local market appears to respond effectively to the urban population's diverse needs through its low-cost and high-cost segments, although uncertainty around the quality of generics may be inducing consumers to purchase less affordable drugs. We conclude that local markets play a larger than expected role in the determination of prices in Mozambique, and that more research is needed to address the complex issue of affordability of medicines in low-income countries. We also argue that price controls may not be the most effective way to influence access to medicines in low-income countries, and managing demand and supply towards cheaper effective drugs appears a more suitable policy option.

Comparative cost analysis of insecticide-treated net delivery strategies: sales supported by social marketing and free distribution through antenatal care

Mon, 14 Sep 2009 08:38:16 PDT

Insecticide-treated nets (ITNs) are effective in substantially reducing malaria transmission. Still, ITN coverage in sub-Saharan Africa (SSA) remains extremely low. Policy makers are concerned with identifying the most suitable delivery mechanism to achieve rapid yet sustainable increases in ITN coverage. Little is known, however, on the comparative costs of alternative ITN distribution strategies. This paper aimed to fill this gap in knowledge by developing such a comparative cost analysis, looking at the cost per ITN distributed for two alternative interventions: subsidized sales supported by social marketing and free distribution to pregnant women through antenatal care (ANC). The study was conducted in rural Burkina Faso, where the two interventions were carried out alongside one another in 2006/07. Cost information was collected prospectively to derive both a financial analysis adopting a provider's perspective and an economic analysis adopting a societal perspective. The average financial cost per ITN distributed was US$8.08 and US$7.21 for sales supported by social marketing and free distribution through ANC, respectively. The average economic cost per ITN distributed was US$4.81 for both interventions. Contrary to common belief, costs did not differ substantially between the two interventions. Due to the district's ability to rely fully on the use of existing resources, financial costs associated with free ITN distribution through ANC were in fact even lower than those associated with the social marketing campaign. This represents an encouraging finding for SSA governments and points to the possibility to invest in programmes to favour free ITN distribution through existing health facilities. Given restricted budgets, however, free distribution programmes are unlikely to be feasible.

Child immunization coverage in urban slums of Bangladesh: impact of an intervention package

Uddin, M. J., Larson, C. P, Oliveras, E., Khan, A I, Quaiyum, M A, Saha, N. C. — Fri, 11 Sep 2009 07:02:03 PDT

The study assessed the impact of an EPI (Expanded Programme on Immunization) intervention package, implemented within the existing service-delivery system, to improve the child immunization coverage in urban slums of Dhaka, Bangladesh. This intervention trial used a pre- and post-test design. An intervention package was tested from September 2006 to August 2007 in two urban slums. The intervention package included: (a) an extended EPI service schedule; (b) training for service providers on valid doses and management of side-effects; (c) a screening tool to identify immunization needs among clinic attendants; and (d) an EPI support group for social mobilization. Data were obtained from random sample surveys, service statistics and qualitative interviews. Analysis of quantitative data was based on a ‘before and after’ assessment of selected immunization-coverage indicators. Qualitative data were analysed using content analysis. Ninety-nine per cent of the children were fully immunized after implementation of the interventions compared with only 43% before implementation. Antigen-wise coverage after implementation was also significantly higher compared with before implementation. Only 1% drop-out was observed after implementation of the interventions while it was 33% before implementation. At baseline, a significantly higher proportion of children of non-working mothers (75%) were fully immunized compared with children of working mothers (14%). Although the proportion of fully immunized children of both non-working and working mothers was significantly higher at endline, fully immunized children of working mothers dramatically improved at endline (99%) compared with baseline (14%). The findings suggest the effectiveness of a ‘package of interventions’ in improving child immunization coverage in urban slums. However, further research is needed to fully assess the effectiveness of the package, to assess the individual components in order to identify those that make the biggest contribution to coverage, and to assess the sustainability of this package within the existing service delivery system, particularly on a wider scale.

Learning from international policies on trans fatty acids to reduce cardiovascular disease in low- and middle-income countries, using Mexico as a case study

Perez-Ferrer, C., Lock, K., Rivera, J. A — Wed, 09 Sep 2009 08:22:19 PDT

Trans fatty acids (TFA) are a major risk factor for cardiovascular disease (CVD), and are consumed in large quantities in low- and middle-income countries as they are used to produce low cost, commonly eaten processed food products. International organizations agree that evidence linking TFA and CVD is strong enough to warrant public health action.

This study investigates barriers and opportunities that exist for TFA policy development in low- and middle-income countries, through a literature review of international TFA policy and stakeholder analysis. Previous national policy responses have mostly been in developed countries. Voluntary reduction of TFA by the food industry, following food labelling and/or consumer lobbying, has been the approach in several countries but with varying levels of success, and resulting in major differences in formulation of products between countries. Canada and New York have now moved from voluntary to mandatory approaches. Only three countries have regulated the TFA content of food. Common factors for successful TFA reduction include increased consumer and political awareness of the health impacts of TFA and the need for champion consumer organizations.

A stakeholder analysis, using the Mexican policy context as a case study, explored contextual issues influencing implementation of TFA regulation in low- or middle-income countries. Although the public health context seemed to be appropriate to promote TFA policy, the issue is not on the political agenda because it lacks legitimacy and support as a health or regulatory issue. The food industry and government resist the need for regulation, and there is no organized health or consumer lobby to counter this. This is likely to be the case in other middle- and low-income countries.

"This body does not want free medicines": South African consumer perceptions of drug quality

Patel, A., Gauld, R., Norris, P., Rades, T. — Wed, 02 Sep 2009 07:09:46 PDT

Objectives Like many other developing countries, South Africa provides free medicines through its public health care facilities. Recent policies encourage generic substitution in the private sector. This study explored South African consumer perceptions of drug quality and whether these perceptions influenced how people procured and used their medicines.

Methods The study was undertaken in Durban, Cape Town and Johannesburg in South Africa between December 2005 and January 2006. A combination of purposive and snowball sampling was used to recruit participants from low and middle socio-economic groups as well as the elderly and teenagers. Data were collected through 12 focus group discussions involving a total of 73 participants. Interviews were tape-recorded. Thematic analysis was performed on the transcripts.

Results Irrespective of socio-economic status, respondents described medicine quality in terms of the effect the medicine produced on felt symptoms. Generic medicines, as well as medicines supplied without charge by the state, were considered to be poor quality and treated with suspicion. Respondents obtained medicines from three sources: public sector hospitals and/or clinics, dispensing doctors and community pharmacies. Cost, avoidance of feeling ‘second-class’, receiving individualized care and choice in drug selection were the main determinants influencing their procurement behaviour. Selection of over-the-counter medicines was influenced by prior knowledge of products, through advertising and previous use. Participants perceived that they had limited influence on selection of prescription medicines. Generic substitution would be supported if the doctor, rather than the pharmacist, recommended it.

Conclusions Our findings emphasize the importance of meaningful consumer involvement in the development of national medicines policies, and strategic campaigns targeting consumers and prescribers regarding the quality of generic and essential medicines. Where consumers perceive free or generic medicines as inferior, this could significantly undermine attempts to implement national medicines policies aimed to improve access to medicines.
