Addressing the needs of people with extensively drug-resistant TB through pre-approval access to drugs and research.

Multiple therapeutic options exist for people with drug-resistant TB (DR-TB), but there is an urgent need to improve access to novel compounds and regimens for people with difficult to treat forms of TB. In additional to formal research studies and clinical trials, other mechanisms of accessing promising new TB compounds need to be introduced as soon as these drugs have shown efficacy and safety in phase II trials. Pre-approval access programs for newer TB drugs such as bedaquiline, delamanid, and pretomanid all suffered from shortcomings. These can be addressed for the next generation of new TB drugs through a series of concerted actions by stakeholders at multiple levels. In this viewpoint, we advocate for transparent, accessible pre-approval access as a core element of person-centered care for DR-TB.

Il existe de nombreuses options thérapeutiques pour les personnes atteintes de TB résistante aux médicaments (DR-TB), mais il est urgent d'améliorer l'accès aux nouvelles molécules et aux nouveaux schémas thérapeutiques pour les personnes atteintes de formes de TB difficiles à traiter. Outre les études de recherche formelles et les essais cliniques, d'autres mécanismes d'accès aux nouvelles molécules prometteuses contre la TB doivent être mis en place dès que ces médicaments ont démontré leur efficacité et leur innocuité lors des essais de phase II. Les programmes d'accès avant approbation pour les nouveaux médicaments contre la TB tels que la bédaquiline, le delamanid et le pretomanid ont tous souffert de lacunes. Ces problèmes peuvent être résolus pour la prochaine génération de nouveaux médicaments contre la TB grâce à une série d'actions concertées entre les parties prenantes à différents niveaux. Dans cette optique, nous préconisons un accès transparent et accessible avant approbation, en tant qu'élément central des soins centrés sur la personne pour la DR-TB.

One size does not fit all: community views on choices for TB treatment and prevention.

Treatment and prevention paradigms in TB have been dominated by a 'one-size-fits-all' approach, in which all persons are given the same treatment regimens. This stands in contrast to other health conditions, where differentiated models of care have been shown to be effective. In this Viewpoint, we make the case for considering multiple factors when deciding which regimens should be offered to people with TB infection and disease. Choice about which regimens to use should be made in conjunction with people who have TB and consider efficacy, safety, duration, pill burden, formulation, drug interactions, time spent in monitoring, drug susceptibility, compatibility with other areas of life, and availability of support services. Ideally, these choices should be considered within an equity framework with the most intensified services being offered to those considered most vulnerable.

Les paradigmes de traitement et de prévention de la TB ont été dominés par une approche « unique ¼, dans laquelle toutes les personnes reçoivent les mêmes schémas thérapeutiques. Cette approche contraste avec d'autres problèmes de santé, pour lesquels des modèles de soins différenciés se sont avérés efficaces. Dans ce point de vue, nous plaidons en faveur de la prise en compte de multiples facteurs au moment de décider des schémas thérapeutiques à proposer aux personnes atteintes de infection tuberculeuse et de TB maladie. Le choix des traitements doit être fait en collaboration avec les personnes atteintes de TB et tenir compte de l'efficacité, de l'innocuité, de la durée, du nombre de comprimés, de la formulation, des interactions médicamenteuses, du temps consacré à la surveillance, de la sensibilité aux médicaments, de la compatibilité avec d'autres domaines de la vie et de la disponibilité des services d'aide. Idéalement, ces choix devraient être envisagés dans un cadre d'équité, les services les plus intensifs étant proposés aux personnes considérées comme les plus vulnérables.

A feasibility study using time-driven activity-based costing as a management tool for provider cost estimation: lessons from the national TB control program in Zimbabwe in 2018.

BACKGROUND: Insufficient cost data and limited capacity constrains the understanding of the actual resources required for effective TB control. This study used process maps and time-driven activity-based costing to document TB service delivery processes. The analysis identified the resources required to sustain TB services in Zimbabwe, as well as several opportunities for more effective and efficient use of available resources. METHODS: A multi-disciplinary team applied time-driven activity-based costing (TDABC) to develop process maps and measure the cost of clinical pathways used for Drug Susceptible TB (DS-TB) at urban polyclinics, rural district and provincial hospitals, and community based targeted screening for TB (Tas4TB). The team performed interviews and observations to collect data on the time taken by health care worker-patient pairs at every stage of the treatment pathway. The personnel's practical capacity and capacity cost rates were calculated on five cost domains. An MS Excel model calculated diagnostic and treatment costs. FINDINGS: Twenty-five stages were identified in the TB care pathway across all health facilities except for community targeted screening for TB. Considerable variations were observed among the facilities in how health care professionals performed client registration, taking of vital signs, treatment follow-up, dispensing medicines and processing samples. The average cost per patient for the entire DS-TB care was USD324 with diagnosis costing USD69 and treatment costing USD255. The average cost for diagnosis and treatment was higher in clinics than in hospitals (USD392 versus USD256). Nurses in clinics were 1.6 time more expensive than in hospitals. The main cost components were personnel (USD130) and laboratory (USD119). Diagnostic cost in Tas4TB was twice that of health facility setting (USD153 vs USD69), with major cost drivers being demand creation (USD89) and sputum specimen transportation (USD5 vs USD3). CONCLUSION: TDABC is a feasible and effective costing and management tool in low-resource settings. The TDABC process maps and treatment costs revealed several opportunities for innovative improvements in the NTP under public health programme settings. Re-engineering laboratory testing processes and synchronising TB treatment follow-up with antiretroviral treatments could produce better and more uniform TB treatments at significantly lower cost in Zimbabwe.
