ABSTRACT
INTRODUCTION: Successful treatment of TB requires high levels of adherence to treatment. This has been found to be below optimal with directly observed therapy (DOT), and digital adherence technologies (DATs) offer a promising approach to non-adherence to medication and improving treatment outcomes. This study explores the perception, acceptability, and challenges of DATs among healthcare workers (HCWs). METHODS: The study was conducted in eight states in Nigeria among Health Care workers involved in treating patients with TB. This was a descriptive cross-sectional study using an open questionnaire and analysed using IBM SPSS v25. RESULTS: Twenty-three HCWs (95.8%) agreed that DATs helped them provide better support and counselling to their patients. All of them would recommend DATs to their patients and found it easy to explain them. Eleven (45.8%) of them were not able to use DATs on a few occasions; their reasons were poor network (n = 9, 37.5%) and (n = 1, 4.2%) power failure. CONCLUSION: DATs help HCWs provide better support and care regarding real-time tracking of their patients' adherence to treatment and possibly reduction of attrition. This implies that DATs are a suitable alternative to DOT to help HCWs provide the best care and support to their patients towards achieving the End TB targets.
INTRODUCTION: Le traitement réussi de la TB nécessite des niveaux élevés d'observance du traitement. Cela s'est avéré inférieur à l'optimal avec le traitement sous observation directe, et les technologies d'observance numérique (DAT) offrent une approche prometteuse de la non-observance des médicaments et de l'amélioration des résultats du traitement. Cette étude explore la perception, l'acceptabilité et les défis des DAT chez les travailleurs de la santé (HCW, pour l'anglais « healthcare worker ¼). MÉTHODES: L'étude a été menée dans huit États du Nigeria auprès de travailleurs de la santé impliqués dans le traitement des patients atteints de TB. Il s'agissait d'une étude transversale descriptive utilisant un questionnaire ouvert et analysée à l'aide d'IBM SPSS v25. RÉSULTATS: Vingt-trois HCW (95,8%) ont convenu que les DAT les aidaient à fournir un meilleur soutien et des conseils à leurs patients. Tous recommandaient les fichiers DAT à leurs patients et trouvaient facile de les expliquer. Onze d'entre eux (45,8%) n'ont pas pu utiliser les fichiers DAT à quelques reprises, en raison d'une mauvaise qualité du réseau (n = 9 ; 37,5%) et d'une panne de courant (n = 1 ; 4,2%). CONCLUSION: Les DAT aident les HCW à fournir un meilleur soutien et des soins en ce qui concerne le suivi en temps réel de l'observance du traitement par leurs patients et éventuellement la réduction de l'attrition. Cela implique que les DAT sont une alternative appropriée au DOT pour aider les travailleurs de la santé à fournir les meilleurs soins et le meilleur soutien à leurs patients pour atteindre les objectifs de l'éradication de la TB.
ABSTRACT
INTRODUCTION: Poor adherence to TB treatment poses a significant public health threat to TB control programmes. The sustainability of directly observed treatment has been questioned because of its non-patient-centred approach and resource-intensive nature, and Digital Adherence Technologies (DATs) provide a suitable alternative. This study assessed the feasibility and acceptability of DATs among patients with TB. METHODS: This descriptive study was conducted in eight states in Nigeria among all patients with drug-susceptible TB. RESULT: A total of 230 patients (89.1%) own a phone that no one else uses, and 18 (7.0%) use a family phone. A higher proportion of 189 (73.3%) have airtime credit and 119 (46.1%) have internet credit on their phone. In addition, 216 (83.7%) stated that the reminders they received on their phone helped them remember to take their medicine. Only 11 (4.3%) patients missed a dose of the TB medicine. Equally, 11 (4.3%) patients had taken their TB medicine without using DAT. Of these, 7 (63.3%) did not use DATs because they forgot to text medication labels, and 3 (27.6%) did so because of poor network. Only four (1.6%) purchased additional items to support the use of DATs. CONCLUSION: DATs are acceptable in a wide variety of settings, even with reported challenges. Implementation efforts should ensure access, address technical challenges, and minimise additional cost to patients.
INTRODUCTION: La mauvaise observance du traitement antituberculeux constitue une menace importante pour la santé publique pour les programmes de lutte contre la TB. La durabilité du traitement sous observation directe a été remise en question en raison de son approche non centrée sur le patient et de sa nature gourmande en ressources, et les technologies d'observance numérique (DAT) constituent une alternative appropriée. Cette étude a évalué la faisabilité et l'acceptabilité des DAT chez les patients atteints de TB. MÉTHODES: Cette étude descriptive a été menée dans huit États du Nigeria auprès de tous les patients atteints de TB pharmacosensible. RÉSULTAT: Un total de 230 patients (89,1%) possèdent un téléphone que personne d'autre n'utilise, et 18 (7,0%) utilisent un téléphone familial. Une proportion plus élevée de 189 (73,3%) ont du crédit de temps d'antenne et 119 (46,1%) ont du crédit Internet sur leur téléphone. De plus, 216 (83,7%) ont déclaré que les rappels qu'ils ont reçus sur leur téléphone les ont aidés à se rappeler de prendre leurs médicaments. Seuls 11 patients (4,3%) ont manqué une dose du médicament antituberculeux. De même, 11 patients (4,3%) avaient pris leur médicament antituberculeux sans utiliser de DAT. De ce nombre, 7 (63,3%) n'ont pas utilisé de fichiers DAT parce qu'ils ont oublié d'envoyer des étiquettes de médicaments par texto, et 3 (27,6%) l'ont fait en raison d'un réseau médiocre. Seulement quatre (1,6%) ont acheté des articles supplémentaires pour soutenir l'utilisation des fichiers DAT. CONCLUSION: Les fichiers DAT sont acceptables dans une grande variété de contextes, même en cas de problèmes signalés. Les efforts de mise en Åuvre doivent garantir l'accès, relever les défis techniques et minimiser les coûts supplémentaires pour les patients.
ABSTRACT
SETTING: KNCV Nigeria implements seven key TB case-finding interventions. It was critical to evaluate the efficiency of these interventions in terms of TB yield to direct future prioritisation in the country. OBJECTIVES: To compare the efficiency of active case-finding (ACF) interventions for TB in Nigeria. DESIGN: Data from the 2020-2022 implementing period were analysed retrospectively. Intervention efficiencies were analysed using the number needed to screen (NNS), the number needed to test (NNT) and the true screen-positive (TSP) rate. RESULTS: Across the interventions, 21,704,669 persons were screened for TB, 1,834,447 (8.5%) were presumed to have TB (7.7% pre-diagnostic drop-out rate) and 122,452 were diagnosed with TB (TSP rate of 7.2%). The average TSP rate of interventions that used both the WHO four-symptom screen (W4SS) and portable digital X-ray (PDX) screening algorithm was significantly higher (22.6%) than those that employed the former alone (7.0%; OR 3.9, 95% CI 3.74-3.98; P < 0.001). The average NNT for interventions with W4SS/PDX screening was 4 (range: 4-5), while that of W4SS-only screening was 14 (range: 11-22). CONCLUSIONS: Interventions using the PDX in addition to W4SS for TB screening were more efficient in terms of TB case yield than interventions that used symptom-based TB screening only.
CONTEXTE: KNCV Nigeria met en Åuvre sept interventions clés de recherche de cas de TB. Il était essentiel d'évaluer l'efficacité de ces interventions en termes de rendement de la TB afin d'orienter les priorités futures dans le pays. OBJECTIFS: Comparer l'efficacité des interventions de recherche active de cas (ACF) pour la TB au Nigéria. MÉTHODE: Les données de la période de mise en Åuvre 20202022 ont été analysées, rétrospectivement. L'efficacité des interventions a été analysée à l'aide du nombre nécessaire pour dépister (NNS), du nombre nécessaire pour tester (NNT) et du taux de vrais dépistages positifs (TSP). RÉSULTATS: Sur l'ensemble des interventions, 21 704 669 personnes ont bénéficié d'un dépistage de la TB, 1 834 447 (8,5%) ont été présumées atteintes de la TB (taux d'abandon pré-diagnostic de 7,7%) et 122 452 ont reçu un diagnostic de TB (taux de TSP de 7,2%). Le taux moyen de TSP des interventions qui utilisaient à la fois le test des quatre symptômes de l'OMS (W4SS) et l'algorithme de dépistage par radiographie numérique portable (PDX) était significativement plus élevé (22,6%) que celles qui utilisaient uniquement le premier (7,0% ; OR 3,9 ; IC 95% 3,743,98 ; P < 0,001). Le NNT moyen des interventions avec dépistage W4SS/PDX était de 4 (intervalle : 45), tandis que celui du dépistage W4SS seul était de 14 (intervalle : 1122). CONCLUSIONS: Les interventions utilisant le PDX en plus du W4SS pour le dépistage de la TB ont été plus efficaces en termes de nombre de cas de TB que les interventions utilisant uniquement le dépistage de la TB basé sur les symptômes.

SETTING: This pilot project was conducted in hard-to-reach communities of two Niger Delta States in the South-South Region of Nigeria. OBJECTIVE: To assess the usefulness of portable digital X-ray, the Delft-Light Backpack (DLB) for TB active case-finding (ACF) in hard-to-reach Niger Delta communities using the WHO 3B TB screening/diagnosis algorithm. DESIGN: DLB X-ray was used to screen all consenting eligible participants during community TB screening out-reaches in all hard-to-reach communities of Akwa Ibom and Cross River States in the Niger Delta, Nigeria. Participants with a CAD4TB (computer-aided detection for TB score) ⩾60 had Xpert (sputum) and/or clinical (radiograph) assessment for TB diagnosis. Data from the project were analysed for this study. RESULTS: A total of 8,230 participants (males: 47.2%, females: 52.8%) underwent TB screening and 1,140 (13.9%) presumptive TB cases were identified. The TB prevalence among all participants and among those with presumptive TB were respectively 1.2% and 8.6%. The number needed to screen was 84. Among people with presumptive TB, the proportion of males and females with confirmed TB was respectively 12.0% and 5.6% (P < 0.001). CONCLUSION: TB screening using DLB X-ray during community-based ACF in hard-to-reach Niger Delta communities of Nigeria showed a high TB prevalence among participants. Nationwide deployment of the instrument in hard-to-reach areas is recommended.
CONTEXTE: Ce projet pilote a été réalisé auprès de communautés difficiles à atteindre des deux états du delta du Niger dans la région sud-sud du Nigéria. OBJECTIF: Évaluer l'utilité du système de radiographie DLB pour la recherche active de cas de TB (ACF) dans les communités isolées de la région du delta du Niger, en utilisant l'algorithme 3b de l'OMS pour le dépistage/diagnostic de la TB. MÉTHODES: La radiographie DLB a été utilisée pour dépister tous les participants éligibles et consentants lors d'interventions de dépistage de la TB auprès de toutes les communités isolées des États d'Akwa Ibom et de Cross River de la région du delta du Niger. Les participants avec un score CAD4TB ⩾60 ont fait l'objet d'un test Xpert (crachats) et/ou d'une évaluation clinique (radiographie) à des fins de diagnostic de la TB. Les données du projet ont été analysées aux fins de l'étude. RÉSULTATS: Un total de 8 230 participants (hommes : 47,2%, femmes : 52,8%) ont fait l'objet d'un dépistage de la TB et 1 140 (13,9%) cas suspects de TB ont été identifiés. La prévalence de la TB parmi tous les participants et parmi les cas suspects de TB était respectivement de 1,2% et 8,6%. Le nombre nécessaire au dépistage était de 84. Parmi les cas suspects de TB, la proportion d'hommes et de femmes chez qui une TB a été confirmée était respectivement de 12,0% et 5,6% (P<0,001). CONCLUSION: Le dépistage de la TB par radiographie DLB lors d'activités ACF auprès des communités isolées de la région du delta du Niger au Nigéria, a démontré une prévalence élevée de la TB chez les participants. Le déploiement national de ce système auprès des communautés isolées est recommandé.
ABSTRACT
BACKGROUND: Tuberculosis (TB) preventive therapy (TPT), including isoniazid preventive therapy (IPT), has been implemented within the Nigerian human immunodeficiency virus (HIV) programme since 2014. However, drug procurement and logistic support has remained the responsibility of the National Tuberculosis and Leprosy Control Programme. The US President's Emergency Plan for AIDS Relief-Nigeria (PEPFAR Nigeria) reviewed the key bottlenecks to TPT implementation in 2016. METHOD: The logistics of delivery of isoniazid (INH) were integrated with the antiretroviral (ARV) logistics management and information system (LMIS). Drug order and requisition forms at the facility level were revised to include INH, along with training on appropriate quantification and requisition of INH with ARVs. Support was provided for last mile delivery of INH directly to every implementing site, alongside ARV. REULTS: We observed an increasing trend in TPT uptake between the pre-and-post intervention periods: 6% in fiscal year (FY) 2015, 7% in FY2016 and 12% in FY2017. Overall, the logistical changes in the LMIS to include INH in 2016 led to a 69% increase in TPT by the end of FY2017; this was statistically significant. CONCLUSION: Addressing logistical challenges to TPT implementation will ensure that the TB and HIV programmes can tackle the increasing burden of TB infection in people living with HIV. We recommended that the provider-to-client stage of TPT implementation be driven by the HIV programme and that cross-communication between the two programmes be improved.
ABSTRACT
BACKGROUND: Active TB case finding (ACF) is a key strategy employed by the National Tuberculosis and Leprosy Control Programme (NTBLCP) to address the increasing gap in TB case finding in Nigeria. KNCV TB foundation Nigeria rolled out two high-impact ACF interventions; TB Surge and the Wellness on Wheels (WoW) campaigns from January 2020. METHOD: The TB Surge intervention supports the engagement of ad hoc staff for TB ACF. The WoW campaign employs a mobile diagnostic unit to deliver care to the doorstep of people at risk of TB. Data along the TB cascade are recorded for all clients using the CommCare app. Cochran-Armitage χ2 test for linear trend was used to assess the significance declining trends along the TB cascade. RESULTS: There was a progressive decrease of respectively 63%, 64%, 73% and 72% in clinic attendance, presumptive TB identification, TB cases detected and treatment initiation for the TB Surge ACF intervention since the emergence of coronavirus; a similar decrease was noted for the WoW intervention. Trend analysis showed a significant decline in trends for both interventions for all variables (P < 0.001). CONCLUSION: The COVID-19 epidemic has impacted negatively on TB services in Nigeria. The TB programme could leverage some resources used to combat the epidemic such as digital health technology and funds, and work towards strengthening patient-centred approach to care to limit the challenges that COVID-19 presents to TB control.
ABSTRACT
BACKGROUND: Nigeria has a high burden of HIV and tuberculosis (TB). To reduce TB-associated morbidity and mortality, the World Health Organization recommends that HIV-positive TB patients receive antiretroviral therapy (ART) within eight weeks of TB treatment initiation, or within two weeks if profoundly immunosuppressed (CD4<50 cell/µL). METHODS: TB and HIV clinical records from facilities in two Nigerian states between October 1st, 2012 and September 30th, 2013 were retrospectively reviewed to assess uptake and timing of ART initiation among HIV-positive TB patients. Healthcare workers were qualitatively interviewed to assess TB/HIV knowledge and barriers to timely ART. RESULTS: Data were abstracted from 4,810 TB patient records, of which 1,249 (26.0%) had HIV-positive or unknown HIV status documented, and the 574 (45.9%) HIV-positive TB patients were evaluated for timing of ART uptake relative to TB treatment. Among 484 (84.3%) HIV-positive TB patients not already on ART, 256 (52.9%, 95% CI: 45.0-60.8) were not initiated on ART during six months of TB treatment. 30.0% of 273 patients with a known CD4≥50cells/µL started ART within eight weeks, and 14.8% of 54 patients with a known CD4<50cells/µL started within the recommended two weeks. Only 42% of health workers interviewed reported knowing to interpret guidelines on when to initiate ART in HIV-positive TB patients based on CD4 cell count results. CD4 cell count significantly predicted timely ART uptake. CONCLUSION: A large proportion of HIV-positive TB patients were not initiated on ART early or even at all during TB treatment. Retraining of staff, and interventions to strengthen referral systems should be implemented to ensure timely provision of ART among HIV-positive TB patients in Nigeria.
ABSTRACT
Tuberculosis (TB) is the leading cause of death among people living with HIV/AIDS worldwide. HIV fuels the TB epidemic in populations such as in Nigeria where there is overlap between those infected with HIV and those infected with Mycobacterium tuberculosis. To address the enormous challenges posed by the dual TB/HIV infection; the Nigerian National Tuberculosis and Leprosy Control Programme (NTBLCP) began collaborative TB/HIV services in Gombe State with some other selected states in 2006. The study looked at 300 new sputum smear-positive acetate-free biofiltration (AFB) patients that had tested positive to HIV screening between diagnosis and second month of follow-up; and were treated between January and December 2006 in the Gombe State TB control programme. The control for the study came from the same cohort of January to December 2006 of new sputum smear-positive AFB patients (595) who had tested negative to HIV screening. The cohort analysis looked at the HIV sero-prevalence and the treatment outcomes: cure rate; failure rate; death rate; default rate; and transfer out rate among new smear pulmonary tuberculosis (PTB) patients that are dually infected with HIV and TB as compared to those not dually infected. The majority of HIV-positive and HIV-negative PTB patients studied were aged 39 years and below. There was no statistically significant difference between the mean age of patients with co-infection and those without co-infection. The majority of the co-infected patients were aged up to 30 years. There was a statistically significant difference in the mean age of males and females. Of the 300 HIV co-infected patients in the study population that were HIV positive; males accounted for 58.3compared with 41.7females. This was not statistically significance. TB patients that were HIV positive had a cure rate of 12.7; while those that were HIV negative had a cure rate of 31.8. The death rate among dually infected patients was higher compared with the HIV-negative patients. The treatment completion and default rates were higher in the HIV co-infected patient
