Background: Pakistan is classified as a high-burden country for tuberculosis, and the prescription of antibiotics and fluoroquinolones complicates the detection and treatment of the disease. The existing literature primarily relies on knowledge questionnaires and prescription analyses, which focus on healthcare providers’ knowledge rather than their actual clinical practices. Therefore, this study aimed to evaluate the quality of tuberculosis care using standardized patients. Materials and Methods: We conducted a cross-sectional study, recruiting consenting private healthcare practitioners in four cities in Punjab, Pakistan. Standardized patients were engaged from the general public to simulate four cases: two suspected tuberculosis cases (Case 1 and 2), one confirmed tuberculosis case (Case 3), and one suspected multidrug-resistant tuberculosis case (Case 4). The optimal management in Cases 1 and 2 was referral for sputum testing, chest X-ray, or referral to a public facility for directly observed treatment short-courses without dispensing antibiotics, fluoroquinolones, and steroids. In Case 3, treatment with four anti-TB medications was expected, while Case 4 should have prompted a drug-susceptibility test. Descriptive statistics using SPSS version 23 were employed to analyze disparities in referrals, ideal case management, antibiotic use, steroid administration, and the number of medications prescribed. Results: From July 2022 to May 2023, 3321 standardized cases were presented to private healthcare practitioners. Overall, 39.4% of tuberculosis cases were managed optimally, with Case 3 showing the highest rate (56.7%) and Case 4 showing the lowest (19.8%). City-specific analysis revealed that Rawalpindi had the highest management rate (55.8%), while Sialkot had the lowest (30.6%). Antibiotics were most frequently prescribed in Case 1 and least prescribed in Case 4, with a similar pattern for fluoroquinolones. Anti-TB medications were also prescribed in naïve and suspected tuberculosis cases (8.3% in Case 1 and 10.8% in Case 2). Conclusions: The quality of tuberculosis management in actual practice is suboptimal among healthcare providers in Pakistan. Furthermore, the over-prescription of antibiotics, fluoroquinolones, and anti-TB drugs presents a significant risk for the development of drug-resistant tuberculosis. Full article

Background: The number of foreign-born patients with tuberculosis (TB) has been increasing in Japan, and the number of Vietnamese patients was the highest in 2019. Tuberculosis (TB) is the second leading cause of death from infectious diseases after coronavirus disease-2019 (COVID-19). As the prevalence of TB varies widely globally, measures must be tailored to local characteristics. The Directly Observed Treatment (DOTS) short-course was introduced by the World Health Organization as a global strategy to overcome these challenges. The purpose of this study is to develop an original risk assessment for treatment interruption for Vietnamese patients with TB to be used in Directly Observed Treatment (DOTS), a tuberculosis control measure. Methods: The researchers adopted the Delphi method. Public health nurses of mid-career or above (n = 15) who had conducted DOTS for several Vietnamese patients with TB were selected and surveyed about the content and surface validities of the draft risk assessment items for treatment interruption. The survey was conducted three times. The quantification of content validity and the review and modification of responses regarding each item were analyzed by the researchers. Results: The results identified the following risk categories: “physical characteristics”, “background of life during residence”, “treatment environment”, “understanding tuberculosis and disease acceptance”, and “cultural and value trends”. Conclusions: The results suggest the need to provide support for tuberculosis recovery from various perspectives, including the living environment of Vietnamese patients with TB, their social environment in Japan, and the culture and values of their country of birth and upbringing.

(1) Background: Achieving successful tuberculosis (TB) treatment outcomes among diabetic patients is a real challenge as TB complicates control of diabetes. This study aimed to evaluate the effectiveness of an integrated dual management educational module, MID-DOTS, which uses the mmotivational interviewing (MI) technique implemented within directly observed treatment as part of a short course (DOTS) program in TB patients with diabetes (TB/DM). A randomized controlled trial was conducted in the northeastern state of Malaysia. (2) Methods: One hundred and twenty-four TB patients with diabetes received educational intervention using a MID-DOT module that used the MI technique, which was repetitively applied by TB nurses throughout a 6-month DOTS program while another 122 patients were given standard health education. Study outcomes include the proportion of patients with successful TB treatment, and changes in HbA1c and diabetic self-care scores at 6 months. (3) Results: The successful TB treatment outcome was 88% in the intervention group versus 72% in the control group (RR = 1.24; 95%CI 1.16, 1.58). A significant reduction of HbA1c (mean difference 0.82%; 95%CI 0.66, 0.98) and significantly higher diabetes self-care score (mean difference 8.49; 95%CI 7.38, 9.59) were also shown in the intervention group. (4) Conclusions: A dual TB/DM educational strategy which integrates the MI technique applied repetitively within the DOTS program is effective in increasing successful TB treatment as well as improving diabetic outcomes.

Tuberculosis (TB) is one of the oldest human diseases, and preventing treatment failure is critical. This is because TB cases pose a risk to the immediate and remote communities due to the potential for spread, particularly for multidrug-resistant (MDR) strains that have been associated with higher morbidity and mortality rates. Hence, this study looked at the factors that influence TB treatment outcomes in Southwest Nigeria. We conducted a cross-sectional study with 712 TB patients from 25 directly observed treatment short course (DOTS) centers, out of which 566 (79.49%) were new treatment cases, and 102 (14.33%) were retreatment cases. The outcome variable was computed into successful treatment where ‘Yes’ was assigned to TB treatment completed and cured, and ‘No’ was assigned to all the remaining outcomes following the standard TB definition. Independent variables included in the analysis were the patient’s socio-demographic characteristics (such as age, sex, distance from the facility, marital status, family type, education, and computed socioeconomic status from modified DHS household assets), clinical and facility parameters (such as the HIV status, facility of access to healthcare, healthcare workers attitudes, services offered at the facility, appearance of the facility, number of people seeking care and waiting time at the facility). Bivariate analysis showed that HIV status (OR: 3.53, 95% CI: 1.83–6.82; p = 0.001), healthcare worker attitude (OR: 2.13, 95% CI: 1.21–3.74; p = 0.01), services offered at the facility (OR: 0.67, 95% CI: 0.49–0.92; p = 0.01), appearance of facility (OR: 0.67, 95% CI: 0.46–0.98; p = 0.04), and number of people seeking care (OR: 2.47, 95% CI: 1.72–3.55; p = 0.001) were associated with higher odds of successful treatment outcome with statistical significance. After multivariate analysis, reactive HIV status (aOR: 3.37, 95% CI: 1.67–6.80; p = 0.001), positive attitude of healthcare workers (aOR: 2.58, 95% CI: 1.36–4.89; p = 0.04), excellent services offered at the healthcare facility (aOR: 0.53, 95% CI: 0.36–0.78; p = 0.001) and few people seeking care (aOR: 2.10, 95% CI: 1.21–3.84; p = 0.001) became independent significant determinants of successful treatment outcome. The study concluded that reactive HIV status, positive attitude of healthcare workers, few people seeking healthcare, and excellent service provided were all factors that contributed to successful treatment outcomes.

A sharp increase in migrant workers has raised concerns for TB epidemics, yet optimal TB control strategies remain unclear in Taiwan regions. This study assessed intervention efforts on reducing tuberculosis (TB) infection among migrant workers. We performed large-scale data analyses and used them to develop a control-based migrant worker-associated susceptible–latently infected–infectious–recovered (SLTR) model. We used the SLTR model to assess potential intervention strategies such as social distancing, early screening, and directly observed treatment, short-course (DOTS) for TB transmission among migrant workers and locals in three major hotspot cities from 2018 to 2023. We showed that social distancing was the best single strategy, while the best dual measure was social distancing coupled with early screening. However, the effectiveness of the triple strategy was marginally (1–3%) better than that of the dual measure. Our study provides a mechanistic framework to facilitate understanding of TB transmission dynamics between locals and migrant workers and to recommend better prevention strategies in anticipation of achieving WHO’s milestones by the next decade. Our work has implications for migrant worker-associated TB infection prevention on a global scale and provides a knowledge base for exploring how outcomes can be best implemented by alternative control measure approaches.

(1) Background: Tuberculosis is a bacterial disease mainly caused by Mycobacterium tuberculosis. It is one of the major public health problems in the world and now ranks alongside human immunodeficiency virus (HIV) as the leading infectious cause of death. The objective of this study was to investigate the potential risk factors affecting the time to death of TB patients in southwest Ethiopia using parametric shared frailty models. (2) Methods: A retrospective study design was used to collect monthly records of TB patients in three selected hospitals in southwest Ethiopia. The data used in the study were obtained from patients who took part in the directly observed treatment, short-course (DOTS) program from 1 January 2015 to 31 December 2019. The survival probability was analyzed by the Kaplan–Meier method. Log-rank tests and parametric shared frailty models were applied to investigate factors associated with death during TB treatment. (3) Results: Out of the total sample of 604 registered TB patients, 46 (7.6%) died during the study period and 558 (92.4%) were censored. It was found that the median time of death for TB patients was 5 months. Hospitals were used to assess the cluster effect of the frailty model. A Gamma shared frailty model with Weibull distribution for baseline hazard function was selected among all models considered and was used for this study. It was found that the covariates, age, initial weight, extrapulmonary type of TB patient, patient category, and HIV status of TB patient were significant risk factors associated with death status among TB patients. (4) Conclusions: The risk of death was high, especially with cases of HIV co-infected, retreated, and returned-after-treatment categories of TB patients. During the treatment period, the risk of death was high for older TB patients and patients with low baseline body weight measurements. Therefore, health professionals should focus on the identified factors to improve the survival time of TB patients. Full article

The case detection rate of childhood tuberculosis in Bangladesh is 4%, far below the World Health Organization predicted rate of 10–15% for a country with a high burden of tuberculosis. A concurrent triangulation mixed-methods study was carried out in eight urban DOTS (Directly Observed Treatment, Short-course) centres to investigate the factors contributing to the diagnosis and treatment of childhood tuberculosis. Front-line health care workers (Shasthya Shebika) (n = 111) were surveyed to understand knowledge, attitude, and practice (KAP) of the diagnosis and treatment of childhood tuberculosis. In-depth interviews were conducted with field workers (n = 32) and mothers of TB cases (n = 4). Stakeholders involved in implementing the tuberculosis program (n = 9) participated in the key informant interviews. Knowledge of Shasthya Shebika was associated with the components addressed during refresher training (p = 0.02). Government stewardship, presence of specific guidelines, knowledge and capacity building of front-line health workers were identified as the key facilitators. Frequent turnover of key managerial positions in the government, stigma, delays in seeking care, lack of diagnostic facilities, and poor engagement of private practitioners were identified as major constraints. It was identified that the government should focus on improving diagnostic capacities, conduct research on childhood tuberculosis, and produce awareness materials. Full article

We propose a new framework to improve the engagement of medical practitioners in a planned e-training platform for the successful identification and effective management of presumptive cases of tuberculosis (TB) in Pakistan. Our work is aligned with the World Health Organization’s TB-DOTS (Directly Observed Treatment Short-course) strategy for promoting the effective management of tuberculosis. We start by presenting previous work done at Mercy Corps Pakistan for training medical practitioners, then present the results of a recent survey we administered to a random sample of medical practitioners in Pakistan to learn about their requirements and readiness to embrace a new e-training platform and methodology. Informed by feedback from the survey, we formulated a detailed requirement analysis of the five key learning areas (or phases) that we believe are fundamental to the success of a TB e-training platform. Moreover, survey results revealed that an on-spot, on-demand, and competency-based learning tool can potentially improve the engagement of medical practitioners in the process. Building on the insights gained from the survey, we finally describe our initial UX (user experience) prototypes for phase 1, which corresponds to the identification of presumptive tuberculosis cases.

Tuberculosis (TB) is a global public health concern, specifically in countries which have high prevalence of HIV/AIDS, malnutrition, unhygienic conditions, etc. Some evidence has been presented that diabetes mellitus (DM) is a risk factor for TB. On the other hand, among those who have DM, TB infection enhances glucose intolerance and worsens glycemic control. The combination of TB and DM, due to immuno-compromised status of DM, can delay the healing process of TB. The focus of this paper is the World Health Organization directly observed treatment, short course (DOTS) program implemented in Gazan province, Saudi Arabia, to treat TB. The data included some patients with both TB and DM. The data has been analyzed to assess how effective the DOTS program was in managing TB. It was found that DM was not a significant factor in the outcome of TB treatment. We used the same data and observed that the non-significance of DM is due to heterogeneity of patient population, Saudis and Non-Saudis. The prevalence of DM was very high among Saudis. This is understandable in view of different lifestyles. Non-Saudis are predominantly Yemenis. For Saudis, DM was indeed found to play a role in the treatment outcome of TB, after an application of a classification tree methodology on the data. This is the main focus of the paper.

Introduction: The aim of the study was to evaluate treatment outcomes in sputum culture positive patients with tuberculosis in three Polish provinces (Warsaw, Gdansk and Siedlce Provinces) in 1995 and again in 2000. We also assessed whether the implementation of the Directly Observed Therapy Short Course (DOTS) strategy in the former Gdansk Province led to improved outcomes compared to the outcomes observed in 1995, when this strategy was not being followed. Material and methods: We started the study by reviewing microbiology registers covering the years 1995 and 2000 from all the tuberculosis laboratories in three provinces (Warsaw, Gdansk and Siedlce Provinces) and identified sputum culture positive patients. We then reviewed inpatient and outpatient medical records of patients who had been with pulmonary tuberculosis diagnosed and confirmed by bacteriology in 1995 and 2000. Treatment outcomes were evaluated in accordance with the World Health Organisation (WHO) recommendations and classified as: cure, treatment completed, default, treatment failure, death or other. Results: A total of 708 patients were included in the study: 373 diagnosed in 1995 and 335 diagnosed in 2000. According to the WHO criteria, the treatment success rate (the sum of cures and treatment completions) in 1995 and 2000 was 58.8% and 54.0%, the default rate was 15.5% and 17.9%, the failure rate was 2.4% and 2.7% and the death rate was 5.6% and 6.3%, respectively. The rate of outcomes classified as “other” was 18.2% and 22.1%, respectively. Following the implementation of the DOTS strategy in Gdansk Province, treatment outcomes in significantly improved in 2000 compared to the year 1995. The treatment success rate was 89.6% vs. 69.3% (p = 0.0037), the default rate was 0.0% vs. 14.7% (p = 0.0005) and the death rate was 0.0% vs. 9.3% (p = 0.0184). Conclusions: The treatment success rate (the rate of cures and treatment completers) in 1995 and 2000 was 58.8% and 54.0% and was lower than that recommended by WHO (at least 85%). The results demonstrated that the treatment outcomes in the former Gdansk Province in 2000, following the implementation of the DOTS strategy, were significantly better than those in 1995, when the strategy was not being followed. Treatment success was observed in 89.6% and 69.3% of the patients, respectively (p = 0.0037). Full article
