Acceptability of Active Case Finding with a Seed-and-Recruit Model to Improve Tuberculosis Case Detection and Linkage to Treatment in Cambodia: A Qualitative Study

Background With support of the national tuberculosis (TB) program, KHANA (a local non-governmental organization in Cambodia) has implemented an innovative approach using a seed-and-recruit model to actively find TB cases in the community. The model engaged community members including TB survivors as seed and newly diagnosed people with TB as recruiters to recruit presumptive TB cases in their social network in a snowball approach for screening and linkage to treatment. This study aimed to explore the acceptability of the active case finding with the seed-and-recruit model in detecting new TB cases and determine the characteristics of successful seeds. Methods This qualitative study was conducted in four provinces (Banteay Meanchey, Kampong Chhnang, Siem Reap, and Takeo) in Cambodia in 2017. Fifty-six in-depth interviews and ten focus group discussions (with a total of 64 participants) were conducted with selected beneficiaries and key stakeholders at different levels to gain insights into the acceptability, strengths, and challenges in implementing the model and the characteristics of successful seeds. Transcripts were coded and content analyses were performed. Results The seed-and-recruit active case finding model was generally well-received by the study participants. They saw the benefits of engaging TB survivors and utilizing their social network to find new TB cases in the community. The social embeddedness of the model within the local community was one of the major strengths. The success of the model also hinges on the integration with existing health facilities. Having an extensive social network, being motivated, and having good knowledge about TB were important characteristics of successful seeds. Study participants reported challenges in motivating the presumptive TB cases for screening, logistic capacities, and high workload during the implementation. However, there was a general consensus that the model ought to be expanded. Conclusions These findings indicate that the seed-and-recruit model is well-accepted by the beneficiaries and key stakeholders. Further studies are needed to more comprehensively evaluate the impacts and cost-effectiveness of the model for future expansion in Cambodia as well as in other resource-limited settings

Market penetration of Xpert MTB/RIF in high tuberculosis burden countries: A trend analysis from 2014 - 2016 [version 1; referees: 4 approved]

Background: Xpert® MTB/RIF, a rapid tuberculosis (TB) molecular test, was endorsed by the World Health Organization in 2010. Since then, 34.4 million cartridges have been procured under concessional pricing. Although the roll out of this diagnostic is promising, previous studies showed low market penetration. Methods: To assess 3-year trends of market penetration of Xpert MTB/RIF in the public sector, smear and Xpert MTB/RIF volumes for the year 2016 were assessed and policies from 2014-2016 within 22 high-burden countries (HBCs) were studied. A structured questionnaire was sent to representatives of 22 HBCs. The questionnaires assessed the total smear and Xpert MTB/RIF volumes, number of modules and days of operation of GeneXpert machines in National TB Programs (NTPs). Data regarding the use of NTP GeneXpert machines for other diseases and GeneXpert procurement by other disease control programs were collected. Market penetration was estimated by the ratio of total sputum smear volume for initial diagnosis divided by the number of Xpert MTB/RIF tests procured in the public sector. Results: The survey response rate was 21/22 (95%). Smear/Xpert ratios decreased in 17/21 countries and increased in four countries, since 2014. The median ratio decreased from 32.6 (Q1:14.3, Q3: 58.9) in 2014 to 6.0 (Q1: 1.6, Q3: 17.0) in 2016. Nineteen countries (19/19; 100%) were not using GeneXpert machines to their full capacity, however seven countries (7/19; 37%) were running tests for other diseases on their NTP-procured GeneXpert systems in 2017, such as HIV, hepatitis-C virus (HCV), Chlamydia trachomatis, and Neisseria gonorrhoeae. Five (5/15; 33%) countries reported GeneXpert procurement by HIV or HCV programs in 2016 and/or 2017. Conclusions: Our results show a positive trend for Xpert MTB/RIF market penetration in 21 HBC public sectors. However, GeneXpert machines were under-utilized for TB, and inadequately exploited as a multi disease technology

Building the health-economic case for scaling up the WHO-HEARTS hypertension control package in low- and middle-income countries

Generally, hypertension control programs are cost-effective, including in low- and middle-income countries, but country governments and civil society are not likely to support hypertension control programs unless value is demonstrated in terms of public health benefits, budget impact, and value-for-investment for the individual country context. The World Health Organization (WHO) and the Pan American Health Organization (PAHO) established a standard, simplified Global HEARTS approach to hypertension control, including preferred antihypertensive medicines and blood pressure measurement devices. The objective of this study is to report on health economic studies of HEARTS hypertension control package cost (especially medication costs), cost-effectiveness, and budget impact and describe mathematical models designed to translate hypertension control program data into the optimal approach to hypertension care service delivery and financing, especially in lowand middle-income countries. Early results suggest that HEARTS hypertension control interventions are either cost-saving or cost-effective, that the HEARTS package is affordable at between US$18-44 per person treated per year, and that antihypertensive medicines could be priced low enough to reach a global standard of an average <US$ 5 per patient per year in the public sector. This health economic evidence will make a compelling case for government ownership and financial support for national scale hypertension control programs

Regionalization and the Closure of 52 Hospitals in Rural Saskatchewan

In the early 1990s Canada was in a recession and the government of Saskatchewan felt the pressure of a growing deficit. In 1992, the provincial government decided to reduce the health care budget by 3.3%. The following year, the government undertook regionalization of health care services through the Health Districts Act, with a focus on promoting preventative health care rather than solely treatment-based care. The budget cuts resulted in the closure of 52 rural hospitals, leading to a public outcry. Evaluations of the reform were not able to show a definite detrimental effect on health outcomes in the corresponding communities. Community members expressed increased caregiver burden, travel costs and travel time to the next nearest hospital, and potential inequalities in access to care. When undertaking reform, it is important that government consider the voices of local communities in the decision-making process. Au début des années 90, le Canada était en récession et, en Saskatchewan, le déficit budgétaire posait un problème pressant au gouvernement provincial. Celui-ci décida de réduire le budget de la santé de 3,3% en 1992. L’année suivante, le gouvernement mit en place une régionalisation des services de santé fondée sur la Loi sur les Districts de Santé, avec comme objectif de favoriser la prévention par rapport aux soins purement curatifs. 52 hôpitaux ruraux durent fermer à cause des coupes budgétaires, entraînant une réaction de rejet de la part du public. Les évaluations de la réforme n’ont pas pu établir avec certitude une détérioration de la santé dans les communautés concernées. Les habitants des communautés concernées ont exprimé une charge accrue pour les aidants, des coûts et temps de transports plus élevés pour se rendre à l’hôpital le plus proche, et d’éventuelles inégalités d’accès aux soins. Les voix des populations concernées devraient être écoutées lors de la prise de décision sur de telles réformes

Quality of tuberculosis care in high burden countries: the urgent need to address gaps in the care cascade

SummaryDespite the high coverage of directly observed treatment (DOTS), tuberculosis (TB) continues to affect 10.4 million people each year, and kills 1.8 million. High TB mortality, the large number of missing TB cases, the emergence of severe forms of drug resistance, and the slow decline in TB incidence indicate that merely expanding the coverage of TB services is insufficient to end the epidemic. In the era of the End TB Strategy, we need to think beyond coverage and start focusing on the quality of the TB care that is routinely offered to patients in high burden countries, in both public and private sectors. In this review, current evidence on the quality of TB care in high burden countries, major gaps in the quality of care, and some novel efforts to measure and improve the quality of care are described. Based on systematic reviews on the quality of TB care or surrogates of quality (e.g., TB diagnostic delays), analyses of TB care cascades, and newer studies that directly measure quality of care, it is shown that the quality of care in both the public and private sector falls short of international standards and urgently needs improvement. National TB programs will therefore need to systematically measure and improve quality of TB care and invest in quality improvement programs
