Public Health Progress in Haiti.

Although the attention of the Haitian public and international community has understandably turned to the recurrent political challenges facing the country and recovery from Hurricane Mathew, it is important that public health stakeholders take stock of progress made, remaining gaps, and fundamental public health priorities. In the past year, the global community has assessed progress toward the Millennium Development Goals (MDGs) and established new health targets under the Sustainable Development Goals framework.[1] Haiti has made progress toward the MDGs and many of the objectives established in the aftermath of the earthquake.[1-7] Important lessons regarding the association between various global health emergency responses, such as to human immunodeficiency virus (HIV), tuberculosis (TB), Ebola (Haitian public health professionals deployed to Guinea), and health sector resiliency have been identified.[8,9] Yet much remains to be done to increase health service access and to reduce morbidity and mortality from preventable causes in the country. Although the public health system in Haiti has been improved since the earthquake, emergency response and health recovery funding has largely focused on new and acute threats such as Zika virus.[10] Moreover, the health-care delivery infrastructure remains fragile, with limited coverage of primary care services, suboptimal health-care performance, and excessive health risk and vulnerability for the Haitian population. It is in this context that the Supplement, entitled “Public Health Progress in Haiti,” was developed. The reports enclosed span HIV, TB, malaria, cholera, immunizations, rabies, water, sanitation and hygiene, and lymphatic filariasis, and also address notifiable disease surveillance reporting and national laboratory capacity.[11-20] Collectively, they appraise some of the key programs and services that have been the focus of postearthquake response and recovery planning and which have central roles informing current and future strengthening and prioritization within the health sector.

The notifiable disease surveillance system has been expanded and strengthened, facilitated by an improved public health workforce.[11] Public health laboratory capacity has been broadened and sustained, benefitting both disease surveillance and response, and clinical services.[12] TB case notification and detection rates have increased, in part due to expansion of TB laboratory diagnostics and other case detection efforts.[13] HIV clinical surveillance efforts have advanced, leveraging national patient-level information systems to enable robust analyses of the clinical cascade, including retention on HIV antiretroviral treatment—an unprecedented achievement for a country facing a generalized epidemic.[14] Collaborative research in lymphatic filariasis and malaria has enabled progress toward and underpinned commitments to elimination goals on both fronts.[15,16] The national immunization program has advanced specific elimination goals while introducing new vaccines and strengthening surveillance and response for vaccine-preventable diseases.[17] Novel rabies surveillance efforts have better defined burden of disease and enabled prevention services in the country.[18] Targeted research on and innovative collaboration promoting access to safe water has informed national strategic planning for control of cholera and other diarrheal diseases.[19] Finally, efforts to expand coverage of the oral cholera vaccine in a targeted manner have contributed to ongoing national cholera elimination efforts in the face of challenges recently heightened by Hurricane Mathew[20,21] (Table 1).

There are several relevant frameworks for considering the current status of health services and public health programs in Haiti, including those used by the Pan American Health Organization and the World Health Organization, as well as the essential public health services which have been developed to serve as a complementary paradigm with a more explicit focus on public health aspects.[22-25] The Government of Haiti’s (GOH) health sector strategic plan, and the assessments and prioritization exercises that were performed during the early phases of emergency response planning, all remain key reference points and will be touched on throughout the various articles presented herein.[26] Although broad and diverse, these reports do not address all important aspects of public health, such as maternal and child health, in depth. However, our hope is that, taken together, these reports will help to illuminate some of the tremendous public health gains made, and lessons learned, through the leadership of the GOH in close partnership with national and international partners.

Two issues remain central to the challenges and opportunities facing Haiti’s health sector today: financing and governance. As official data from the national health accounts vividly portray, as recently as 2004, the GOH allocated > 15% of total national expenditures to health.[27] However, from 2005 to present, and coinciding both with the introduction of major global health financing initiatives from the Global Fund to Fight AIDS, Tuberculosis and Malaria and the U.S. President’s Emergency Plan for AIDS Relief, as well as the earthquake and cholera epidemic in 2010, there is evidence of substantial displacement of host government financing of the health sector due to external financial support, as well as the slow recovery of GOH revenues postearthquake.[28] In the past few years, while total health spending has increased, GOH health allocations have decreased to < 5% of the national budget,[28] despite the efforts of the Ministry of Public Health and Population (MSPP) to seek and advocate for increased health financing across other GOH institutions. Even during recent stretches of Haitian history with similar political difficulties, health allocations by the GOH remained closer to the 15% international benchmark,[29] suggesting greater effort is needed from within the GOH, civil society, and the international community to increase emphasis on the importance of increasing and sustaining health allocations. The 2015 health financing conference convened by MSPP and health donors was a step in this direction, but the creative proposals developed need to be carried forth by the new government.[2]

Governance is another crucial public health functional domain which, although hard to define and measure, is essential to long-term public health progress. Governance and health financing are integrally intertwined, as stable financial support to hire and retain adequate human resources for health at all levels is a prerequisite for institutional capacity building and stepwise gains in sustainability. Entire units and programs within MSPP remain dependent on external donor financing to sustain adequate staffing levels and to prevent the loss of skilled workforce (“brain drain”).[30] Such limitations can be addressed systematically with preservice educational capacity, novel health financing, and robust governance capacity within the public health sector. Only in this manner will the reputed “Republic of NGO’s”[31] be able to establish health services and programs with a public sector backbone to promote stability and continuity, and, above all, support national efforts to provide universal access to health care. Only this will improve the health of Haitians who continue to face the worst health metrics in the Western Hemisphere.[32]

Although addressing country ownership for financing and governance is critical for ensuring that progress across public health programs in postearthquake Haiti is sustained, stronger partnerships between international and indigenous organizations are still needed to solve the greatest public health challenges. These include increasing access to clean water and improved sanitation; eliminating cholera; achieving and sustaining 90% immunization coverage for all routinely administered childhood vaccines; and ensuring supply chain for HIV antiretroviral treatment, essential cholera response commodities-like oral rehydration solution, and robust second-line drug regimens for treatment of multidrug-resistant TB.

The global health community is developing new initiatives to more effectively prepare for emerging public health threats and emergencies.[33] Haiti’s recent experiences should both inform these efforts in other countries and regions, and ensure ongoing and legitimate partnership in the years ahead. The public health progress characterized by the reports in this Supplement should be cause for confidence and for hope that such critical efforts can and will continue even without the extraordinary impetus of disasters and emergencies, even as Haiti continues its recovery from yet another devastating storm. Given the existing and longstanding socioeconomic realities, the GOH and international donor community must be pragmatic and incremental in considering the issue of sustainability in this context.[34,35] Focus on maintaining essential public health services, with emphasis on surveillance, laboratory capabilities, workforce capacity development, and emergency preparedness and response, while shoring up key health system building blocks such as health financing and governance, will define a pathway to maintain the hard-won momentum that has been achieved, and which should not be squandered.
