Addressing knowledge gaps and prevention for tuberculosis-infected Indian adults: a vital part of elimination

Evaluating Treatment Outcomes and Tuberculosis Infection Risks: A Comparative Study of Centralized Hospitalization vs. Home-Based Treatment

Background: Guizhou Province in Southwest China has experimented with a centralized hospitalization (CH) treatment for active and severe cases of pulmonary tuberculosis (PTB). The objective of this study was to compare treatment outcomes of patients with tuberculosis (TB) receiving care in a CH setting with those receiving home-based (HB) care. In addition, this study aimed to assess the probability of their household contacts contracting tuberculosis infection. Method: A retrospective review of medical records was undertaken for patients with TB who completed their treatment in four counties in Guizhou, China, spanning from January 2022 to August 2023. In addition, a cross-sectional survey was conducted on the tuberculin skin test (TST) among household contacts of new patients with TB who had completed their treatment. Results: In the retrospective study, 94.8% had successful CH treatment, and 93.1% had successful HB treatment (p value = 0.70). In the prospective study, 559 and 448 household contacts of patients receiving CH treatment had 16 positive and 89 negative TST results, whereas those with HB treatment showed 26 positive and 74 negative TST results. Regarding a logistic regression analysis, the CH group was nearly two times more likely to test negative on the TST, 1.95 (95% CI: 0.98, 3.92). After adjusting for confounding variables, the odds ratio increased significantly to 4.42 (95% CI: 1.22, 16.04). Conclusions: CH for treatment of TB did not show superior success rates, but it may reduce the risk of transmitting tuberculosis infection to household contacts compared to home treatment.

How can we improve latent tuberculosis infection management using behaviour change wheel: a systematic review

BACKGROUND

To ensure the effective delivery of latent tuberculosis infection (LTBI) care, it is vital to overcome potential challenges in LTBI management. This systematic review aims to identify the barriers and interventions to improve LTBI management using the Capability, Opportunity, and Motivation-Behaviour (COM-B) model and Behaviour Change Wheel (BCW).

METHODS

A systematic literature search was performed on five electronic databases from database inception to 3 November 2021. A two-step technique was used in the data synthesis process: (i) the barriers of LTBI management were identified using the COM-B model, followed by (ii) mapping of intervention functions from BCW to address the identified barriers.

RESULTS

Forty-seven eligible articles were included in this review. The findings highlighted the need for a multifaceted approach in tackling the barriers in LTBI management across the public, provider and system levels. The barriers were summarized into suboptimal knowledge and misperception of LTBI, as well as stigma and psychosocial burden, which could be overcome with a combination of intervention functions, targeting education, environment restructuring, persuasion, modelling, training, incentivization and enablement.

CONCLUSIONS

The remedial strategies using BCW to facilitate policy reforms in LTBI management could serve as a value-added initiative in the global tuberculosis control and prevention program.

Awareness about tuberculosis and RNTCP services among rural people in Nalgonda district, Telangana

Background:

Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis discovered in ancient centuries still remains a major public health problem in India. Lack of awareness about the cause, risk factors, treatment and prevention of TB among rural people is a major challenge to be addressed to reduce disease transmission.

Aims:

To assess the knowledge of TB among rural people. To assess the awareness about RNTCP services.

Settings and Design:

Cross-sectional study was conducted in six randomly selected villages attached to a medical college.

Methods and Materials:

Houses were selected by systematic random sampling method and younger person was identified as study subject. Data were collected from a sample of 300 by predesigned pretested semi-structured questionnaire.

Statistical Analysis Used:

Data were presented in proportions with confidence interval and Chi-square test was applied to find the association between variables by using SPSS ver. 23.

Results:

The study showed that 79.6% knew that the cause of TB is bacteria. Majority of the participants 93.6% (95% CI: 90.3, 96.1) knew that TB primarily affects lungs. Subjects were aware of free diagnostic services (85.3%), free treatment services (89%) available in the govt setup.

Conclusions:

Although the awareness of symptoms, causative agent, mode of spread was reasonably good, knowledge on availability of DOTS centres, services offered through RNTCP is still poor among rural population.

The role of mass media exposure on tuberculosis knowledge and attitude among migrant and seasonal farmworkers in Northwest Ethiopia

Background

Globally, tuberculosis (TB) is the 10th leading cause of death. Despite no country achieved its target, the world health organization (WHO) proposed a 90–90-90 approach to fastening the end TB strategy. Improvement and progression of TB control need good knowledge and a favorable attitude towards the disease. However, interventions designed don’t take migrants and seasonal farmworkers into account. Therefore, this study aimed at estimating the level of knowledge and attitude on Tuberculosis among migrant and seasonal farmworkers in northwest Ethiopia.

Methods

Community-based cross-sectional study was conducted in the West Gondar zone from October to November 2018. A two-stage cluster sampling was used to select 949 migrant and seasonal farmworkers. Both bivariate and multivariable logistic regression analyses were performed. A p-value of < 0.05 was used to declare statistical significance. The goodness of fit was checked using Hosmer and Lemeshow test.

Results

In this study, (41.8%), (95% CI: 38.73, 45.01) and (50.5%), (95% CI: 47.29, 53.65) of migrants and seasonal farmworkers had good knowledge and a favorable attitude, respectively. The odds of good knowledge among mass media exposed migrants were AOR = 1.42, 95% CI: (1.02, 2.01). Moreover, urban residence and having good knowledge increase the odds of favorable attitude by 1.66, (AOR = 1.7; 95% CI: 1.05, 2.62) and 4.3 (AOR = 4.3, 95%CI: 3.26, 5.75), respectively.

Conclusion

In this study, the overall knowledge and attitude of migrant and seasonal farmworkers on TB were low. Family size and mass media exposure significantly affect knowledge of the migrants on TB. On the other hand, the attitude was affected by urban residence, health information, and having good knowledge. Health promotion interventions, focused on TB cause, mode of transmission, prevention, and treatment are important to migrant and seasonal farmworkers to improve the knowledge and attitude of migrants and seasonal farmworkers.

Solutions to improve the latent tuberculosis Cascade of Care in Ghana: a longitudinal impact assessment

Background

Loss of patients in the latent tuberculosis infection (LTBI) cascade of care is a major barrier to LTBI management. We evaluated the impact and acceptability of local solutions implemented to strengthen LTBI management of household contacts (HHCs) at an outpatient clinic in Ghana.

Methods

Local solutions to improve LTBI management were informed by a baseline evaluation of the LTBI cascade and questionnaires administered to index patients, HHCs, and health care workers at the study site in Offinso, Ghana. Solutions aimed to reduce patient costs and improve knowledge. We evaluated the impact and acceptability of the solutions. Specific objectives were to: 1) Compare the proportion of eligible HHCs completing each step in the LTBI cascade of care before and after solution implementation; 2) Compare knowledge, attitude, and practices (KAP) before and after solution implementation, based on responses of patients and health care workers (HCW) to structured questionnaires; 3) Evaluate patient and HCW acceptability of solutions using information obtained from these questionnaires.

Results

Pre and Post-Solution LTBI Cascades included 58 and 125 HHCs, respectively. Before implementation, 39% of expected < 5-year-old HHCs and 66% of ≥5-year-old HHCs were identified. None completed any further cascade steps. Post implementation, the proportion of eligible HHCs who completed identification, assessment, evaluation, and treatment initiation increased for HHCs < 5 to 94, 100, 82, 100%, respectively, and for HHCs ≥5 to 96, 69, 67, 100%, respectively. Pre and Post-Solutions questionnaires were completed by 80 and 95 respondents, respectively. Study participants most frequently mentioned financial support and education as the solutions that supported LTBI management.

Conclusion

Implementation of locally selected solutions was associated with an increase in the proportion of HHCs completing all steps in the LTBI cascade. Tuberculosis programs should consider prioritizing financial support, such as payment for chest x-rays, to support LTBI cascade completion.
