The dual burden of tuberculosis (TB) and diabetes mellitus (DM) has become a major global public health concern. There is mounting evidence from different countries on the burden of TB and DM comorbidity. The objective of this systematic review was to summarize the existing evidence on prevalence and associated/risk factors of TBDM comorbidity at global and regional levels.
Ovid Medline, Embase, Global health, Cochrane library, Web of science and Scopus Elsevier databases were searched to identify eligible articles for the systematic review. Data were extracted using standardized excel form and pilot tested. Median with interquartile range (IQR) was used to estimate prevalence of TBDM comorbidity. Associated/risk factors that were identified from individual studies were thematically analyzed and described.
The prevalence of DM among TB patients ranged from 1.9% to 45%. The overall median global prevalence was 16% (IQR 9.0%-25.3%) Similarly, the prevalence of TB among DM patients ranged from 0.38% to 14% and the overall median global prevalence was 4.1% (IQR 1.8%-6.2%). The highest prevalence of DM among TB patients is observed in the studied countries of Asia, North America and Oceania. On the contrary, the prevalence of TB among DM patients is low globally, but relatively higher in the studied countries of Asia and the African continents. Sex, older age, urban residence, tobacco smoking, sedentary lifestyle, poor glycemic control, having family history of DM and TB illness were among the variables identified as associated/risk factors for TBDM comorbidity.
This systematic review revealed that there is a high burden of DM among TB patients at global level. On the contrary, the global prevalence of TB among DM patients is low. Assessing the magnitude and risk/associated factors of TBDM comorbidity at country/local level is crucial before making decisions to undertake TBDM integrated services.

Tuberculosis (TB) remains a foremost global public health threat. Active TB control needs geographically accessible health facilities that have quality diagnostics, equipment, supplies, medicines, and staff.
This study aimed at assessing the geographic distribution, physical accessibility, readiness and barriers of health facilities for TB services in East Gojjam zone, Ethiopia.
A convergent parallel design was applied using health facility and geographic data. Data on facility attributes, service availability and readiness were collected by inteviewing TB officers, laboratory heads and onsite facility visits. Coordinates of health facilities and kebele centroids were collected by GPS. We used ArcGIS 10.6 to measure Euclidean distance from each kebele centroids to the nearest health facility. Descriptive statistics were computed by using SPSS version 25. Barriers to TB service readiness were explored by in-depth interviews. NVivo12 was used to thematically analyze the qualitative data.
The overall TB health service coverage (THSC) was 23% (ranging: 10-85%). The mean distance from the nearest health facility was 8km (ranging: 0.5-16km). About 132 (32%) kebeles had poor geographic accessibility to TB services (over 10km distance from the nearest health facility) and had poor facility readiness. Although 114 (95%) health facilities offered at least one TB service, 44 (38.6%) of them had no sputum smear microscopy. The overall TB readiness index was 63.5%: first-line anti-TB drugs (97%), diagnostics (63%), trained staffs, diagnostic and treatment guidelines (53%) and laboratory supplies (41%). Lack of health workers (laboratory personnel), inadequate budget, poor management practice and TB program support, inadequate TB commodity suppliers, and less accessible geographic locations of health facilities were identified as barriers to TB service readiness distribution.
Considerable proportion of the population in the study area have poor access to quality TB diagnostic services due to low THSC and poor facility readiness. Barriers to TB service availability and readiness were health system related. Regular refresher training of health workers on TB, creating mechanisms to attract laboratory personnel to work in the study area and scaling up of sputum smear microscopy services, establishing an efficient mechanism for procurement, distribution, utilization and reporting of TB commodity supplies, and good management practices are crucial to enhance TB service readiness in the study zone.

Delays in diagnosis and treatment of tuberculosis (TB) increases severity of illness and continued transmission of TB in the community. Understanding the magnitude and factors associated with total delay is imperative to expedite case detection and treatment of TB. The aim of this study was to determine the length and analyze factors associated with total delay.
Analytic cross-sectional study was conducted in Jimma Zone, Southwest Ethiopia. All newly diagnosed TB patients > 15 years of age were included from randomly selected eight districts and one town in the study area. A structured questionnaire was applied to collect socio-demographic and clinical data. The median total delay was used to dichotomize the sample into delayed and non-delayed patient categories. Logistic regression analysis was used to analyse the association between independent and outcome variables. A p-value < 0.05 were considered statistically significant.
A total of 1,161 patients were included in this study. The median total delay was 35 days. Patients who had swelling or wound in the neck region were more likely to be delayed than their counterpart [adjusted odds ratio (AOR) = 3.02, 95% confidence interval (CI): 1.62, 5.62]. Women were more likely to experience longer total delay (AOR = 1.46, 95% CI:1.00, 2.14) compared to men. Patients who had poor knowledge of TB were more likely to be delayed compared to those who had good knowledge (AOR = 3.92, 95% CI: 2.65, 5.80).
The present study showed long total delay in diagnosis and treatment of TB. Targeted interventions that enhance TB knowledge and practice, expedite early suspect identification, referral and management of all forms of TB is imperative to reduce total delay in diagnosis and treatment of TB.

Determinants of an unfavorable treatment outcome among tuberculosis patients in the Jimma Zone, Southwest Ethiopia
2024
Background
Tuberculosis (TB) is a major public health challenge in Ethiopia. TB treatment outcomes were suboptimal compared to the expected target of the national TB control Program. The provision of standard anti-TB treatment is the primary component of the directly observed treatment, short-course strategy. The aim of this study was to assess the TB treatment outcomes and the determinants of an unfavorable treatment outcome. The study used a cross-sectional study design at baseline and record review to identify treatment outcomes. A total of 1,161 TB patients were recruited from eight randomly selected districts and one town administration in the Jimma Zone, Ethiopia. Treatment outcomes were grouped into favorable and unfavorable. Of the total participants, 86.9% had a favorable treatment outcome, and 5.7% an unfavorable treatment outcome. The rest were transferred out and not recorded cases. Women were more likely to experience an unfavorable treatment outcome [adjusted odds ratio (AOR) = 1.96, 95% CI 1.06, 3.64]. Patients who were perceived to not be stigmatized were less likely to have an unfavorable treatment outcome (AOR = 0.32, 95% CI 0.15, 0.73). Patients who had a monthly income of > 3,500 Ethiopian
birr
were less likely to have an unfavorable outcome than patients who did not have a regular income (AOR = 0.04, 95% CI 0.01, 0.45). The observed treatment success rate is lower than the World Health Organization’s target of successfully treating > 90% of detected TB cases. It is imperative to ensure that information, education and communication/behavior change communication strategies consider the needs of women and patients with perceived TB stigma. Furthermore, designing locally acceptable and affordable interventions may help to address the financial challenges of TB treatment adherence.

Ethiopia is one of the countries with a high burden of tuberculosis (TB). Jimma Zone has the lowest TB case notification rate compared to the national and World Health Organization's (WHO) targets. The aim of the present study was to identify barriers, and explore the origin of these barriers in relation to TB case finding.
A qualitative study was conducted by using different data collection methods and sources. Sixty in-depth interviews with TB treatment providers, program managers and TB patients were included. In addition, 42 governmental health facilities were observed for availability of resources. Data obtained from the in-depth interviews were transcribed, coded, categorized and thematized. Atlas.ti version 7.1 software was used for the data coding and categorizing.
Inadequate resources for TB case finding, such as a shortage of health-care providers, inadequate basic infrastructure, and inadequate diagnostic equipment and supplies, as well as limited access to TB diagnostic services such as an absence of nearby health facilities providing TB diagnostic services and health system delays in the diagnostic process, were identified as barriers for TB case finding. We identified the absence of trained laboratory professionals in 11, the absence of clean water supply in 13 and the electricity in seven health facilities. Furthermore, we found that difficult topography, the absence of proper roads, an inadequate collaboration with other sectors (such as education), a turnover of laboratory professionals, and a low community mobilization, as the origin of some of these barriers.
Inadequate resources for TB case finding, and a limited access to diagnostic services, were major challenges affecting TB case finding. The optimal application of the directly observed treatment short course (Stop TB) strategy is crucial to increase the current low TB case notification rate. Practical strategies need to be designed to attract and retain health professionals in the health system.

The association between diabetes mellitus (DM) and tuberculosis (TB) is re-emerging worldwide. Recently, the prevalence of DM is increasing in resource poor countries where TB is of high burden. The objective of the current study was to determine the prevalence and analyze associated factors of TB and DM comorbidity in South-Eastern Amhara Region, Ethiopia.
This was a facility based cross-sectional study. All newly diagnosed TB patients attending selected health facilities in the study area were consecutively screened for DM. DM was diagnosed based on the World Health Organization diagnostic criteria. A pre-tested semi-structured questionnaire was used to collect socio-demographic, lifestyles and clinical data. Logistic regression analysis was performed to identify factors associated with TB and DM comorbidity.
Among a total of 1314 patients who participated in the study, the prevalence of DM was estimated at 109 (8.3%). Being female [odds ratio (OR) 1.70; 95% confidence interval (CI) (1.10-2.62)], patients age [41-64 years (OR 3.35; 95% CI (2.01-5.57), 65-89 years (OR 3.18; 95% CI (1.52-6.64)], being a pulmonary TB case [(OR 1.69; 95% CI 1.09-2.63)] and having a family history of DM [(OR 4.54; 95% CI (2.36-8.73)] were associated factors identified with TB and DM comorbidity.
The prevalence of DM among TB patients in South-Eastern Amahra Region is high. Routine screening of TB patients for DM is recommended in the study area.

Tuberculosis (TB) remains a key health menace in Ethiopia and its districts. This study aimed to assess the spatial-temporal clustering of notified pulmonary TB (PTB) cases in East Gojjam Zone, Northwest Ethiopia.
A retrospective study was conducted among all PTB cases reported from 2013-2019. Case notification rates (CNRs) of PTB cases at Kebele (the lowest administrative unit), woreda, and zone levels were estimated. The PTB clustering was done using global Moran's I statistics on Arc GIS 10.6. We used Kulldorff SaTScan 9.6 with a discrete Poisson model to identify statistically significant spatial-temporal clustering of PTB cases at Kebele level. Similarly, a negative binomial regression analysis was used to identify factors associated with the incidence of PTB cases at kebele level.
A total of 5340 (52%) smear-positive and 4928 (48%) smear-negative PTB cases were analyzed. The overall mean CNR of PTB cases at zone, woreda and Kebele levels were 58(47-69), 82(56-204), and 69(36-347) per 100,000 population, respectively. The purely spatial cluster analysis identified eight most likely clusters (one for overall and one per year for seven reporting years) and 47 secondary clusters. Similarly, the space-time scan analysis identified one most likely and seven secondary clusters. The purely temporal analysis also detected one most likely cluster from 2013-2015. Rural residence, distance from the nearest health facility, and poor TB service readiness were factors (p-value <0.05) to PTB incidence at kebele level.
The distribution of PTB cases was clustered. The PTB CNR was low and showed a decreasing trend during the reporting periods. Rural residence, distance from the health facilities, and poor facility readiness were factors of PTB incidence. Improving accessibility and readiness of health facilities mainly to rural and hotspot areas is vital to increase case detection and reduce TB transmission.

Drug-resistant tuberculosis (DR-TB) remains a major health security threat worldwide. The effectiveness of implementation of DR-TB control strategies has been a subject of research and controversy. In resource-limited settings, using conventional medicine as the only framework to explain DR-TB gives a rather incomplete picture of the disease. This study intended to explore the perceptions and experiences of healthcare workers on the management and control of DR-TB in Addis Ababa, Ethiopia.
The study employed a qualitative methodology with an inductive approach and a thematic analysis. It involved in-depth interviews with healthcare workers providing clinical services to DR-TB patients in 10 public healthcare facilities in Addis Ababa, Ethiopia.
A total of 18 healthcare workers participated until data saturation, which included 12 clinical nurses, four health officers and two medical laboratory technicians. The findings show that healthcare workers perceive DR-TB as a growing public health threat in Ethiopia, due to factors such as poverty, poor nutrition, crowded settings, healthcare worker and general public awareness of DR-TB, lack of good governance and culture.
The perspectives drawn from the healthcare workers shed more light on the image of DR-TB in a developing country context. It has been shown that understanding DR-TB is not confined to what can be drawn from the sphere of biomedicine. There are also interconnected barriers, which predict a dystopia in the epidemiology of DR-TB. Bringing DR-TB under control requires taking a step back from an overwhelming focus on the biomedical facets of the disease, and employ critical thinking on the wider social and structural forces as equally important targets.

delay in diagnosis and treatment of tuberculosis (TB) may worsen the disease, increase mortality and enhance transmission in the community. This study aimed at assessing the association between total delay and unfavorable treatment outcome among newly diagnosed pulmonary TB (PTB) patients.
A prospective cohort study was conducted in West Gojjam Zone, Amhara Region of Ethiopia from October 2013 to May 2015. Newly diagnosed PTB patients who were ≥15 years of age were consecutively enrolled in the study from 30 randomly selected public health facilities. Total delay (the time period from onset of TB symptoms to first start of anti-TB treatment) was measured. Median total delay was calculated. Mixed effect logistics regression was used to analyze factors associated with unfavorable treatment outcome.
Seven hundred six patients were enrolled in the study. The median total delay was 60 days. Patients with total delay of > 60 days were more likely to have unfavorable TB treatment outcome than patients with total delay of ≤ 60 days (adjusted odds ratio [AOR], 2.33; 95% confidence interval [CI], 1.04-5.26). Human immunodeficiency virus (HIV) positive TB patients were 8.46 times more likely to experience unfavorable treatment outcome than HIV negative TB patients (AOR, 8.46; 95% CI, 3.14-22.79).
Long total delay and TB/HIV coinfection were associated with unfavorable treatment outcome. Targeted interventions that can reduce delay in diagnosis and treatment of TB, and early comprehensive management of TB/HIV coinfection are needed to reduce increased risk of unfavorable treatment outcome.

Objectives: Existing evidence suggests that drug-resistant tuberculosis (DR-TB) remains a huge public health threat in high-burden TB countries such as Ethiopia. The purpose of this qualitative study was to explore the challenges of healthcare workers (HCWs) involved in providing DR-TB care in Addis Ababa, Ethiopia. Methods: We conducted in-depth interviews with 18 HCWs purposively selected from 10 healthcare facilities in Addis Ababa, Ethiopia. We then transcribed the audiotaped interviews, and thematically analysed the transcripts using Braun and Clark’s reflexive thematic analysis framework. Results: We identified five major themes: 1) inadequate training and provision of information on DR-TB to HCWs assigned to work in DR-TB services, 2) fear of DR-TB infection, 3) risk of contracting DR-TB, 4) a heavy workload, and 5) resource limitations. Conclusion: Our findings highlight major human resource constraints that current DR-TB care policies need to foresee and accommodate. New evidence and best practices on what works in DR-TB care in such resource-limited countries are needed in order to address implementation gaps and to meet global TB strategies.
