One year of COVID-19 and its impact on private provider engagement for TB: A rapid assessment of intermediary NGOs in seven high TB burden countries.

The COVID-19 pandemic has impacted health systems and health programs across the world. For tuberculosis (TB), it is predicted to set back progress by at least twelve years. Public private mix (PPM)has made a vital contribution to reach End TB targets with a ten-fold rise in TB notifications from private providers between 2012 and 2019. This is due in large part to the efforts of intermediary agencies, which aggregate demand from private providers. The COVID-19 pandemic has put these gains at risk over the past year. In this rapid assessment, representatives of 15 intermediary agencies from seven countries that are considered the highest priority for PPM in TB care (the Big Seven) share their views on the impact of COVID-19 on their programs, the private providers operating under their PPM schemes, and their private TB clients. All intermediaries reported a drop in TB testing and notifications, and the closure of some private practices. While travel restrictions and the fear of contracting COVID-19 were the main contributing factors, there were also unanticipated expenses for private providers, which were transferred to patients via increased prices. Intermediaries also had their routine activities disrupted and had to shift tasks and budgets to meet the new needs. However, the intermediaries and their partners rapidly adapted, including an increased use of digital tools, patient-centric services, and ancillary support for private providers. Despite many setbacks, the COVID-19 pandemic has underlined the importance of effective private sector engagement. The robust approach to fight COVID-19 has shown the possibilities for ending TB with a similar approach, augmented by the digital revolution around treatment and diagnostics and the push to decentralize health services.

Harnessing the energy of the corporate sector to end TB: BE health.

The World Health Organization (WHO) estimates that 3 million people with TB are missing' from the official information system. They remain often undiagnosed and untreated or are managed outside the national TB programme structure by various care providers (including the private for-profit sector) and are not notified. The care provided to these patients is often sub-standard, not aligned with national and international guidelines, and un-regulated. WHO has repeatedly underlined the importance of collaborating with the private sector to improve prevention, diagnosis and treatment of TB, Private organisations could join public healthcare institutions' efforts and expand their breadth of interventions to preventive interventions and play a complementary role to the public healthcare systems. Having access to a large scope of employees, customers, suppliers and other stakeholders, corporations should indeed be able to undertake prevention activities utilising their capacity to generate the necessary resources. BE Health is an example of such a private initiative. It was established to build bridges between the workplace and the local communities aiming to empower high-risk populations to address their own major killers such as TB, HIV/AIDS and malaria, within the framework and targets of the United Nations Sustainable Development Goals. In collaboration with healthcare experts, BE Health decided at first to build awareness and spread information on health at the workplace. The approach focused on training newly-formed peer health educators capable of transferring knowledge to their local community. BE Health managed to create a solid network of peer health educators (selected among skilled employees) and community health volunteers selected among slum dwellers) operating in the metropolitan areas of Bangkok and Djibouti and focused on TB and HIV prevention among local impoverished communities. Between 2013 and 2019, 51 peer Health Educators were trained, over 213 health promotion activities were organised at the workplace and more than 4,000 employees were reached through prevention activities, 730 community visits were conducted, over 1900 households were screened for TB and/or HIV with more than 22,000 people reached directly by prevention activities. Similar third party approaches need to be further assessed, harnessed and expanded to complement efforts of the public health sector.

Quality of tuberculosis care in the private health sector.

As countries move towards achieving universal health coverage, efforts to engage all care providers have gained more significance. Over a third of people estimated to have developed TB in 2018 were not detected and notified by national TB programs (NTPs). This gap is more pronounced in countries with large private sectors, especially those with a high burden of TB. Health care providers outside the scope of NTPs, including the private and informal sector, are often the first point of care for TB patients. However, these providers are not fully engaged despite evidence from country experiences and projects that demonstrate increased detection and good treatment outcomes through publicprivate mix (PPM) approaches. While there are often concerns about quality of care in public facilities, there is also increasing evidence that quality of TB care in the private sector falls short of international standards in many places and urgently needs improvement. Failure to engage the full range of health care providers for TB has serious consequences in terms of access to quality care, resulting in increased transmission as a result of delayed diagnosis and treatment; excess mortality and morbidity as a result of inappropriate treatment; and increased drug resistance as a result of incomplete treatment. Recent attention to this issue has led to significant increases in private TB notifications, especially in India, Indonesia and the Philippines, but the gap between notification and the extension of quality program services for provision of treatment and care appears to be growing.

Tools to implement the World Health Organization End TB Strategy: Addressing common challenges in high and low endemic countries.

AIM: The purpose of this viewpoint is to summarize the advantages and constraints of the tools and strategies available for reducing the annual incidence of tuberculosis (TB) by implementing the World Health Organization (WHO) End TB Strategy and the linked WHO TB Elimination Framework, with special reference to Oman. METHODS: The case-study was built based on the presentations and discussions at an international workshop on TB elimination in low incidence countries organized by the Ministry of Health, Oman, which took place from September 5 to September 7, 2019, and supported by the WHO and European Society of Clinical Microbiology and Infectious Diseases (ESCMID). RESULTS: Existing tools were reviewed, including the screening of migrants for latent TB infection (LTBI) with interferon-gamma release assays, clinical examination for active pulmonary TB (APTB) including chest X-rays, organization of laboratory services, and the existing centres for mandatory health examination of pre-arrival or arriving migrants, including examination for APTB. The need for public-private partnerships to handle the burden of screening arriving migrants for active TB was discussed at length and different models for financing were reviewed. CONCLUSIONS: In a country with a high proportion of migrants from high endemic countries, screening for LTBI is of high priority. Molecular typing and the development of public-private partnerships are needed.

Global Fund financing of public-private mix approaches for delivery of tuberculosis care.

OBJECTIVES: To map the extent and scope of public-private mix (PPM) interventions in tuberculosis (TB) control programmes supported by the Global Fund. METHODS: We reviewed the Global Fund's official documents and data to analyse the distribution, characteristics and budgets of PPM approaches within Global Fund supported TB grants in recipient countries between 2003 and 2008. We supplemented this analysis with data on contribution of PPM to TB case notifications in 14 countries reported to World Health Organization in 2009, for the preparation of the global TB control report. RESULTS: Fifty-eight of 93 countries and multi-country recipients of Global Fund-supported TB grants had PPM activities in 2008. Engagement with 'for-profit' private sector was more prevalent in South Asia while involvement of prison health services has been common in Eastern Europe and central Asia. In the Middle East and North Africa, involving non-governmental organizations seemed to be the focus. Average and median spending on PPM within grants was 10% and 5% respectively, ranging from 0.03% to 69% of the total grant budget. In China, India, Nigeria and the Philippines, PPM contributed to detecting more than 25% TB cases while maintaining high treatment success rates. CONCLUSION: In spite of evidence of cost-effectiveness, PPM constitutes only a modest part of overall TB control activities. Scaling up PPM across countries could contribute to expanding access to TB care, increasing case detection, improving treatment outcomes and help achieve the global TB control targets.
