Geographic Information System-based Screening for TB, HIV, and Syphilis (GIS-THIS): A Cross-Sectional Study

Objective To determine the feasibility and case detection rate of a geographic information systems (GIS)-based integrated community screening strategy for tuberculosis, syphilis, and human immunodeficiency virus (HIV). Design Prospective cross-sectional study of all participants presenting to geographic hot spot screenings in Wake County, North Carolina. Methods The residences of tuberculosis, HIV, and syphilis cases incident between 1/1/05–12/31/07 were mapped. Areas with high densities of all 3 diseases were designated “hot spots.” Combined screening for tuberculosis, HIV, and syphilis were conducted at the hot spots; participants with positive tests were referred to the health department. Results and Conclusions Participants (N = 247) reported high-risk characteristics: 67% previously incarcerated, 40% had lived in a homeless shelter, and 29% had a history of crack cocaine use. However, 34% reported never having been tested for HIV, and 41% did not recall prior tuberculin skin testing. Screening identified 3% (8/240) of participants with HIV infection, 1% (3/239) with untreated syphilis, and 15% (36/234) with latent tuberculosis infection. Of the eight persons with HIV, one was newly diagnosed and co-infected with latent tuberculosis; he was treated for latent TB and linked to an HIV provider. Two other HIV-positive persons had fallen out of care, and as a result of the study were linked back into HIV clinics. Of 27 persons with latent tuberculosis offered therapy, nine initiated and three completed treatment. GIS-based screening can effectively penetrate populations with high disease burden and poor healthcare access. Linkage to care remains challenging and will require creative interventions to impact morbidity.

Overcoming Obstacles To Enable Access To Medicines For Noncommunicable Diseases In Poor Countries

The modern access-to-medicines movement grew largely out of the civil-society reaction to the HIV/AIDS pandemic three decades ago. While the movement was successful with regard to HIV/AIDS medications, the increasingly urgent challenge to address access to medicines for noncommunicable diseases has lagged behind-and, in some cases, has been forgotten. In this article we first ask what causes the access gap with respect to lifesaving essential noncommunicable disease medicines and then what can be done to close the gap. Using the example of the push for access to antiretrovirals for HIV/AIDS patients for comparison, we highlight the problems of inadequate global financing and procurement for noncommunicable disease medications, intellectual property barriers and concerns raised by the pharmaceutical industry, and challenges to building stronger civil-society organizations and a patient and humanitarian response from the bottom up to demand treatment. We provide targeted policy recommendations, specific to the public sector, the private sector, and civil society, with the goal of improving access to noncommunicable disease medications globally.

Improving Diabetes Management and Cardiovascular Risk Factors Through Peer-Led Self-management Support Groups in Western Kenya

In sub-Saharan Africa, projections anticipate a 110% rise in the number of people with diabetes mellitus (DM) from 19.8 million to 41.5 million by 2035 (1). This growth is attributed primarily to the multiple downstream ramifications of urbanization and westernization. Poor access to medications, finances, transportation, and skilled health care providers trained in DM management is a barrier that contributes to poor outcomes for patients with DM (2). As a result, patients are often forced to rely on self-management without guidance from the formal health care sector. To combat this barrier, diabetes self-management support (DSMS) programs sustain psychosocial support and education by incorporating lay DM patients as peer support group leaders at the community level (3,4). Limited data exist for DSMS outcomes in low- and middle-income countries (LMICs). The imminent rise of DM and the logistical challenges of health delivery in …

Public health costs for tuberculosis suspects in Wake County, North Carolina, United States.

SETTING As the incidence of tuberculosis (TB) declines in high-income countries, resources to control TB are also declining. A portion of these resources are utilized for the evaluation and treatment of persons initially suspected of, but who do not actually have, TB (TB suspects). OBJECTIVE To describe the cost of TB suspects to public health departments, and determine whether part of this cost can be averted using improved diagnostic tools. DESIGN We evaluated resource utilization for all TB suspects as well as a random sample of TB cases managed at the Wake County public health clinic during 2008-2010. The proportion of total health department costs attributable to TB suspects was estimated. A sensitivity analysis assessed the potential impact of a rapid, accurate diagnostic test to avert suspect-associated costs. RESULTS Of 135 patients evaluated for TB, 36 (27%) were suspects, accounting for 14% (US5,885) of the total estimated costs for managing all patients. A perfect diagnostic test with a 3-day turnaround would have averted US27,975 (53%) of the costs attributable to suspects. CONCLUSION A substantial proportion of public health resources is utilized to manage persons whose final diagnosis is not TB. Efficient implementation of novel rapid tests could avert substantial public health costs.

Increasing access to the MDR-TB surveillance programme through a collaborative model in western Kenya.

Objective  Kenya, like many resource‐constrained countries, has a single mycobacterial laboratory, centrally located in Nairobi, with capacity for drug‐susceptibility testing (DST) – the gold standard in diagnosing drug‐resistant tuberculosis. We describe and evaluate a novel operational design that attempts to overcome diagnostic delivery barriers.

Increasing global access to cancer care: models of care with non-oncologists as primary providers

1000 www.thelancet.com/oncology Vol 18 August 2017 not occurring at random at the population level. Risk calculated at the tissue or organ level should not lead to population-level assumptions. In conclusion, the idea that cancers are caused by bad luck is misleading and dangerous if it leads to policy makers and the public thinking that there is nothing to be done to prevent cancers. Although tumour-cell production might have an inherent stochastic nature, this is just one component of an interaction between complex systems at the individual and population level, which are eminently not random. Medicine and public health need to persist in finding areas of cancer prevention moving above and beyond classic risk factors, taking whole systems—both social and biological—into account.

Cost of Providing Quality Cancer Care at the Butaro Cancer Center of Excellence in Rwanda

Purpose The cost of providing cancer care in low-income countries remains largely unknown, which creates a significant barrier to effective planning and resource allocation. This study examines the cost of providing comprehensive cancer care at the Butaro Cancer Center of Excellence (BCCOE) in Rwanda. Methods A retrospective costing analysis was conducted from the provider perspective by using secondary data from the administrative systems of the BCCOE. We identified the start-up funds necessary to begin initial implementation and determined the fiscal year 2013-2014 operating cost of the cancer program, including capital expenditures and fixed and variable costs. Results A total of

Access to Hemoglobin A1c in Rural Africa: A Difficult Reality with Severe Consequences

556,105 US dollars was assessed as necessary start-up funding to implement the program. The annual operating cost of the cancer program was found to be

A Clinical Mentorship and Quality Improvement Program to Support Health Center Nurses Manage Type 2 Diabetes in Rural Rwanda

957,203 US dollars. Radiotherapy, labor, and chemotherapy were the most significant cost drivers. Radiotherapy services, which require sending patients out of country because there are no radiation units in Rwanda, comprised 25% of program costs, labor accounted for 21%, and chemotherapy, supportive medications, and consumables accounted for 15%. Overhead, training, computed tomography scans, surgeries, blood products, pathology, and social services accounted for less than 10% of the total. Conclusion This study is one of the first to examine operating costs for implementing a cancer center in a low-income country. Having a strong commitment to cancer care, adapting clinical protocols to the local setting, shifting tasks, and creating collaborative partnerships make it possible for BCCOE to provide quality cancer care at a fraction of the cost seen in middle- and high-income countries, which has saved many lives and improved survival. Not all therapies, though, were available because of limited financial resources.
