Health-related quality of life among adults newly diagnosed with pulmonary tuberculosis in Lagos State, Nigeria: a prospective study.

PURPOSE: Tuberculosis (TB) has far-reaching effects on the social, mental, and emotional well-being of patients and consequently, their health-related quality of life (HRQOL). Few studies in Nigeria have examined changes in quality of life over the course of treatment. changes in (PTB) and factors associated with HRQOL. METHODS: A prospective cohort study was conducted with patients recruited from health facilities in Lagos State. The World Health Organization Quality of Life Instrument, Short-Form (WHOQOL-BREF) was used to assess HRQOL. A semi-structured questionnaire was also administered to elicit information on socio-demographic characteristics and the medical and social history of the respondents. Data were analysed using Statistical Package for the Social Sciences (SPSS) version 23. A repeated measures analysis of variance (ANOVA) test with polynomial contrasts was used to assess how domain scores varied over time. Multivariable analysis was conducted using generalized estimating equations (GEE) to assess change in HRQOL and its predictors. RESULTS: Two hundred and ten patients, predominantly male [108 (63.3%)] were recruited. The mean age was 36.7 ± 12.3 years. The HRQOL was impaired in all four domains at baseline. However, HRQOL scores increased over the treatment period with the largest improvement being in the 'environment' domain, where mean scores increased from 45.27 ± 14.59 to 61.28 ± 15.86. The proportion of respondents that expressed satisfaction with their health increased from 13.5% at baseline to 55.7% at the end of treatment. Low socio-economic status, delay in presentation, and an HIV-positive status were found to be significantly associated with reduced HRQOL at baseline (p < 0.05). In the multivariable longitudinal analysis, patients who were employed had higher HRQOL scores while persistent symptoms and a delay in presentation (≥ 4 weeks) were negatively associated with change in HRQOL scores over the course of treatment. CONCLUSION: The HRQOL of respondents progressively improved over the six-month treatment period. However, change in HRQOL was influenced by a delay in presentation and persistence of symptoms. The study also highlights the need for increased recognition of patient-reported outcomes as an adjunct outcome measure.

Factors affecting the readiness for hospital discharge of initially treated pulmonary tuberculosis patients in China: a phenomenological study.

BACKGROUND: Despite readiness for hospital discharge widespread popularity since readiness for hospital discharge introduction in 1979 and extensive study, readiness for hospital discharge among pulmonary tuberculosis (PTB) patients has not yet been investigated. Moreover, the factors influencing this process remain unclear. OBJECTIVE: The objective of this study was to investigate the factors influencing readiness for hospital discharge in initially treated PTB patients using the capability, opportunity, motivation-behavior (COM-B) model. METHODS: This phenomenological study was conducted from December 2023 to March 2024. Face-to-face individual interviews were conducted with 18 initially treated patients with PTB according to a semistructured interview guide developed on the basis of the COM-B model. The interview data were subjected to analysis using NVivo 14 software and Colaizzi's method. RESULTS: As a result, 6 themes and 14 subthemes were identified. Physical capability for readiness for hospital discharge (subthemes included poor health status, early acquisition of adequate knowledge about PTB, inadequate knowledge about readiness for hospital discharge), psychological capability for readiness for hospital discharge(subthemes included false perceptions about readiness for hospital discharge, high treatment adherence), physical opportunity for readiness for hospital discharge (subthemes included high continuity of transition healthcare, insufficient financial support, insufficient informational support), social opportunity for readiness for hospital discharge (subthemes included stigmatization, inadequate emotional support), reflective motivation for readiness for hospital discharge (subthemes included lack of reflection on coping with difficulties, intention to develop a readiness for hospital discharge plan), and automatic motivation for readiness for hospital discharge (subthemes included strong desire to be cured, negative emotions). CONCLUSION: We established factors related to readiness for hospital discharge in initially treated PTB patients in terms of capability, opportunity and motivation, which can inform the future development of readiness for hospital discharge plans. To improve patients' readiness for hospital discharge, patients need to be motivated to plan and desire readiness for hospital discharge, patients' knowledge and treatment adherence should be improved, and patients' transition healthcare continuity and emotional support should be focused on. Moreover, the quality of readiness for hospital discharge and discharge education should be assessed in a timely manner to identify impeding factors and provide interventions.

The correlation between the need for continuing care services, influencing factors, and social support and discharge readiness among discharged patients with pulmonary tuberculosis in China: A cross-sectional study.

OBJECTIVE: To understand the relationship between the need for continuing care services and influencing factors, social support, readiness for discharge among discharged pulmonary tuberculosis (PTB) patients. METHODS: A cross-sectional study was conducted among 170 patients from a database of discharged patients with PTB from September 2023 to January 2024. A demographic and disease characteristics questionnaire, continuing care services basic modality questionnaire, continuing care services need questionnaire, the Social Support Rating Scale (SSRS), and the Readiness for Hospital Discharge Scale (RHDS) were used for this investigation. Univariate analysis and multiple linear regression analysis were used to analyze the associated factors. RESULTS: The mean total score for the need for continuing care services among patients with PTB discharged from the hospital was (121.61 ± 22.98). The dimension with the highest score was health education guidance need. Compared to the the original hospital medical personnel, the primary source of care information after discharge was the local medical institutions was statistically significant and negatively correlated with continuing care service need (P = 0.005). Social support was positively associated with need for continuing care services (P = 0.042). CONCLUSION: Discharged PTB patients had a high degree of continuing care service need. Factors influencing the need for continuing care services are the primary source of care information after discharge was the local medical institutions, the social support. Medical staff need to provide targeted continuing care services based on relevant influencing factors to meet the discharge needs of patients.

Changes in health-related quality of life and the associated factors among Myanmar migrants with tuberculosis: a cohort study.

BACKGROUND: Migrants are known to be predominantly poor population which are predisposing to social and health problems, particularly infectious diseases including tuberculosis (TB). TB itself and effect of treatment may further result in substantial morbidity and lowering the quality of life. This study aimed to assess the changes in health-related quality of life (HRQOL) within six months of anti-TB treatment initiation, and the associated factors in Myanmar migrants under anti-TB treatment within this border area. METHODS: This was a prospective cohort study of adult Myanmar migrants with new TB who were within two months of treatment initiation in two TB clinics in Mae Sot, a Thai-Myanmar border area between September 2019 and July 2020. Eight individual domain scores of the HRQOL and Physical and Mental Component Summary (PCS and MCS) scores measured by SF-36 were calculated at month-2 (T1) as baseline, and at the month-4 (T2) and month-6 follow-up visits (T3). Generalized estimation equation models were used to assess the longitudinal changes in PCS and MCS scores of HRQOL. RESULTS: Of the 155 patients recruited, 93 (60.0%) and 65 (69.9%) completed the month-4 and month-6 follow-ups, respectively. Both the PCS (+ 6.1) and MCS (+ 6.3) scores significantly improved between T1 and T3, with the lowest scores being general health, with the least improvement in social function (+ 1.5) compared with the other domains. Migrants with ethnic origin of Burmese or other were associated with higher PCS and MCS. Those living with family and having higher numbers of initial TB symptoms were associated with lower PCS and MCS scores. Those diagnosed during routine medical checkup were positively associated with PCS scores, whereas patients diagnosed during active case findings were negatively associated with MCS scores. Patients who received residential TB care had higher PCS scores than those with OPD-based TB care. CONCLUSIONS: Continuous improvement in quality of life was found among Myanmar migrants with TB during treatment but their quality of life is still low. Patients with low mental health, especially in the social domain, requires further attention. Active screening policy and supportive strategies during treatment are essential to TB migrants.

Health-related quality of life after pulmonary tuberculosis in South Korea: analysis from the Korea National Health and Nutrition Examination Survey between 2010 and 2018.

BACKGROUND: Although several studies have reported an association between tuberculosis and health-related quality of life, the change in health-related quality of life after pulmonary tuberculosis has been rarely studied. The purpose of this study was to investigate the effect of past history of pulmonary tuberculosis on health-related quality of life using a nationwide, cross-sectional, observational study in Korea. METHODS: Among 72,751 people selected using a stratified multi-stage sampling method, 7260 Korean participants were included using propensity score matching. Past history of pulmonary tuberculosis was defined as a previous diagnosis of pulmonary tuberculosis excluding patients with active pulmonary tuberculosis. The primary outcome, health-related quality of life, was assessed by EQ-5D disutility. RESULTS: Before matching, the mean EQ-5D of individuals with pulmonary tuberculosis history was lower (0.066 vs. 0.056, p: 0.009). However, the difference was nullified after matching (0.066 vs. 0.062, p = 0.354). In multivariable Poisson regression analysis, EQ-5D disutility score was not associated with past pulmonary tuberculosis history. In subgroup analysis, past pulmonary tuberculosis history increased odds of low health-related quality of life in young (odds ratio [OR] 1.57, 95% confidence interval [CI] 1.17-2.11, p = 0.003), unmarried (OR 1.98, 95% CI 1.05-3.73, p = 0.036), or separated patients (OR 1.30, 95% CI 1.02-1.66, p = 0.032). Age and marital status were modulating factors on the effect of past pulmonary tuberculosis history on health-related quality of life. CONCLUSIONS: There was no difference in health-related quality of life between individuals with and without past pulmonary tuberculosis history. Young and unmarried groups had increased odds for low health-related quality of life after pulmonary tuberculosis due to modulating effects of age and marital status.

Implementation fidelity of hospital based directly observed therapy for tuberculosis treatment in Bhutan: mixed-method study.

BACKGROUND: Direct observed treatment (DOT) has been implemented in Bhutan since 1997 and currently, it is offered in various model of delivery including a combination of hospital based, home based DOT and ambulatory DOT. Overall, treatment success rate for tuberculosis cases is higher than the global target; however, it is still need to be improved. Evaluation to the implementation fidelity of DOT is important to identify potential rooms for improvement. This study aimed to assess two major components of the program's implementation fidelity: to assess patient's adherence to DOT and explore factors for adherence; to assess provider's compliance with DOT guideline and explore factors for compliance. METHODS: This research used a sequential explanatory mixed method. The conceptual framework of implementation fidelity was adopted to guide this study design. The cross-sectional study of TB patients was enrolled in two hospitals with highest TB load, between September to November 2017 in Bhutan. Interviewer assisted survey was conducted with 139 TB patients who visited the hospital in continuation phase. In-depth interview was then conducted with nine TB patients and four health staffs to explore the barriers and enablers of DOT. RESULTS: Total of 61.9% (86/139) of patients has received DOT at intensive phase. Proportion was higher among MDR-TB cases (100%), and smear sputum positive TB cases (84.7%). In the continuation phase, 5.8% of patients took medicine at hospital, 48.9% at home and the rest 45.3% no longer practiced DOT. More than 90% of patient received correct dosage and standard regimen of anti-TB drugs according to the guideline. The key factors affecting poor adherence to DOT as perceived by patients were; lack of willingness to visit the clinic on daily basis due to long distance, financial implications and family support. However, patient's satisfaction to the quality of TB treatment service delivery was high (98.6%). Providing incentives to the patient was most agreed enabler felt by both health workers and patients. CONCLUSION: In the selected hospital sites, the patient's adherence to DOT and provider's compliance with DOT guideline is partially implemented; the coverage and the duration of DOT is very low, therefore, need to revise and improve DOT model and structure.

Experimental Pulmonary Tuberculosis in the Absence of Detectable Brain Infection Induces Neuroinflammation and Behavioural Abnormalities in Male BALB/c Mice.

Tuberculosis (TB) is a chronic infectious disease in which prolonged, non-resolutive inflammation of the lung may lead to metabolic and neuroendocrine dysfunction. Previous studies have reported that individuals coursing pulmonary TB experience cognitive or behavioural changes; however, the pathogenic substrate of such manifestations have remained unknown. Here, using a mouse model of progressive pulmonary TB, we report that, even in the absence of brain infection, TB is associated with marked increased synthesis of both inflammatory and anti-inflammatory cytokines in discrete brain areas such as the hypothalamus, the hippocampal formation and cerebellum accompanied by substantial changes in the synthesis of neurotransmitters. Moreover, histopathological findings of neurodegeneration and neuronal death were found as infection progressed with activation of p38, JNK and reduction in the BDNF levels. Finally, we perform behavioural analysis in infected mice throughout the infection, and our data show that the cytokine and neurochemical changes were associated with a marked onset of cognitive impairment as well as depressive- and anxiety-like behaviour. Altogether, our results suggest that besides pulmonary damage, TB is accompanied by an extensive neuroinflammatory and neurodegenerative state which explains some of the behavioural abnormalities found in TB patients.

Health care seeking delay among pulmonary tuberculosis patients in North West zone of Tigrai region, North Ethiopia.

BACKGROUND: Tuberculosis (TB) is a major public health problem and it is among the top 10 causes of death worldwide. One of the challenges against attaining an effective TB control program is delay in seeking health care to diagnosis and treatment of TB patients. The aim of this study was to assess health care-seeking delay among pulmonary TB patients. METHODS: An institutional based cross-sectional study was conducted among new pulmonary tuberculosis (PTB) patients > 15 years of age who were enrolled in the intensive phase TB treatment from November 1, 2015 - January 30, 2016. Data were collected by an interviewer administered technique using a structured questionnaire. Health care seeking delay was categorized by using a median cutoff point of > 30 days as a prolonged health care seeking delay. Logistic regression analyses were employed to determine factors independently associated with the delays in health care seeking. RESULTS: A total of 422 PTB patients were included in this study. The median age of respondents was 37 years (interquartile range (IQR) =35-44). The median time of health care seeking delay was 30 days (IQR) = 21-60). Respondents occupation, knowledge about pulmonary tuberculosis, health facility visited first, seeking treatment from traditional or religious healers before visiting health facilities, reason for not seeking treatment early from health facilities, and reason for first consultation were found to be significantly associated with health care seeking delay. CONCLUSION: The study showed the magnitude of health care seeking delay among pulmonary tuberculosis patient was very long and the factors associated with health care seeking delay were: occupation, knowledge status, health facility visited first and seeking treatment from religious or traditional healer before health facilities. To overcome delay of health care seeking among tuberculosis patients, efforts should required availing tuberculosis diagnostic and treatment services at the primary health care level.

Prevalence of and Factors Influencing Anti-Tuberculosis Treatment Non-Adherence Among Patients with Pulmonary Tuberculosis: A Cross-Sectional Study in Anhui Province, Eastern China.

BACKGROUND To assess the non-adherence rate among pulmonary tuberculosis (TB) patients in Anhui Province, eastern China and to explore the influential factors, so as to identify targets for intervention. MATERIAL AND METHODS A total of 339 TB patients were recruited from TB dispensaries in 8 counties of Anhui Province, eastern China using a stratified sampling method. All study subjects were surveyed using a structured questionnaire. Differences between groups involving categorical data were analyzed using the chi-square test. RESULTS Overall, of the 339 patients, 33.63% missed medication. Divorced and widowed patients were more likely to miss medication compared with those who were married or unmarried (P<0.01). Regarding the knowledge related to topics such as transmission route, preventive measures, and suspicious symptoms, the awareness rate in the group with good medication compliance was higher than in the group with poor compliance (P<0.05). We found that compliance was not significantly associated with seeking medical treatment in professional institutions, the national free TB treatment policy, or discrimination (P>0.05). The rate of non-compliance under supervision (26.10%) was lower than that without supervision (64.18%) (P<0.001). CONCLUSIONS The anti-TB treatment non-adherence rate in TB patients is relatively high in Anhui Province, eastern China, and is associated with marital status, annual income, TB knowledge, and medical staff visits.

Association of social deprivation and outdoor air pollution with pulmonary tuberculosis in spatiotemporal analysis.

The objective of this study was to identify the association between social deprivation, outdoor air pollution, and tuberculosis (TB) incidence rate or mortality rate. The study sample comprised 25 districts in Seoul, Korea. We used two public data derived from the Community Health Survey and Seoul Statistics. The geographic information system analysis and random effects Poisson regression were applied to explore the association of social deprivation and air pollution with TB incidence and mortality. An 1 ppb increase in sulfur dioxide (SO2) concentration was significantly associated with the risk of TB incidence (risk ratio [RR] = 1.046, 95% confidence interval [CI]: 1.028, 1.065). An 1 unit increase in the deprivation index was significantly related to a6% increase in the mortality of TB (RR = 1.063, 95% CI: 1.031, 1.097). : Our results imply that social deprivation and air pollution may affect the different TB outcomes. Effective policy-making for TB control should reflect the differing outcomes between TB incidence and mortality.

Interaction between clinical and psychological changes among patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity.

OBJECTIVE: Introduction: The association of chronic obstructive pulmonary disease and pulmonary tuberculosis is an important medical and social problem with a significant burden in terms of morbidity and mortality. The course and prognosis of chronic diseases such as chronic obstructive pulmonary disease and pulmonary tuberculosis is greatly influenced not only by the clinical features but also by the psychological characteristics of the patient. The aim: To study the interaction between clinical changes and psychological characteristics considering gender differences among patients with chronic obstructive pulmonary disease in association with pulmonary tuberculosis. PATIENTS AND METHODS: Materials and methods: We studied 41patients with chronic obstructive pulmonary disease (grade 2, 3, groups А, B, С, D) and infiltrative pulmonary tuberculosis co-morbidity (11 women and 30 men). All patients underwent general clinical examination, Acid-Fast Bacillus Testing, spirometry, Spielberg anxiety scale, Beck depression scale. RESULTS: Results: Patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity with more severe symptoms (according to Assesment Test scores) were older and, regardless of it, showed elevated depression and personal anxiety scores while situational anxiety scores were significantly lower compared to those with less severe symptoms. The correlation between symptoms severity and airflow limitation or smoking history was very mild. The elevated depression and personal anxiety could cause more severe symptoms. The revealed discrepancy between the symptoms severity and low levels of situational anxiety may be due to adaptation with displacement mechanisms to illness related chronic life stressors. We also observed elevated personal anxiety and depression scores together with less severe symptoms among female versus male chronic obstructive pulmonary disease/pulmonary tuberculosis patients, possibly reflecting physically ill women's higher risk for depressive and anxiety related symptomatology relative to ill men. CONCLUSION: Conclusions: We revealed that among patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity symptoms severity was largely influenced by the patients' age, gender and psychological factors (depression and personal anxiety), but, unexpectedly, much less - by airflow limitation and smoking history. We also found higher emotional distress, namely elevated personal anxiety and depression scores, in combination with less severe symptoms among female versus male patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity.

Why tuberculosis patients under revised national tuberculosis control programme delay in health-care seeking? A mixed-methods research from Wardha District, Maharashtra.

BACKGROUND: Timely treatment of tuberculosis is imperative for its control. This can get delayed due to delay in care seeking, diagnosis or treatment initiation. OBJECTIVES: The study aims to find out the magnitude of delays in care seeking, diagnosis or treatment initiation, and understand the reasons behind these delays in Wardha district of Maharashtra, India. METHODS: A mixed methods study was conducted among 275 patients selected from those enrolled under Revised National Tuberculosis Control Programme in 2014. We collected information regarding the duration of delays and generated a free list of reasons for delays in care seeking and diagnosis. The free list items were then subjected to pile sorting. Two-dimensional scaling and hierarchical clustering analysis were performed to identify the various domains of reasons for delays. RESULTS: The median delay in initial care seeking and diagnosis was 10 days each, and that for treatment initiation was 2 days. The domains identified for delay in care seeking were negligence toward health, health conditions, facility-related issues, and household and social reasons. The domains identified for delay in diagnosis were system-related reasons; and patient-related reasons, each of them further having two subdomains. CONCLUSIONS: Interventions for reducing the knowledge gap and stigma, increasing the accessibility of services, active case finding; capacity building of providers, quality assured sputum microscopy, and communication skills will help reduce these delays.

Development and validation of the pulmonary tuberculosis scale of the system of Quality of Life Instruments for Chronic Diseases (QLICD-PT).

BACKGROUND: Generic assessments are less responsive to subtle changes due to specific diseases, making it challenging to fully understand the impact of pulmonary tuberculosis (TB) on patient's quality of life (QOL). METHODS: We applied programmed decision procedures and theories on instrument development to develop the scale. Two hundred patients with pulmonary TB participated in measuring QOL three times before and after treatments. We assessed the validity, reliability, and responsiveness of QLICD-PT using correlation analysis, factor analysis, multi-trait scaling analysis, randomized block analyses of variance with Least Significant Difference post-hoc tests. RESULTS: We composed QLICD-PT with 3 domains (28 items) for general QOL and 1 pulmonary TB specific domain (12 items). Correlation and factor analysis confirmed good structure validity and criterion-related validity when using Chinese version of the Medical Outcomes Short-Form Health Survey (SF-36) as a criterion. The internal consistency of α values were higher than 0.70. The score changes after treatment were of statistical significance for the overall scale, physical domain and specific domain with effect size ranging from 0.32 to 0.72. No floor effects but small ceiling effects were observed at domain level. CONCLUSIONS: As the first pulmonary TB-specific QOL scale developed by a module approach in Chinese, QLICD-PT has an acceptable degree of validity, reliability and responsiveness, and can be used to measure the life quality of PT patients specifically and sufficiently.

Health-related quality of life among pulmonary tuberculosis patients in Pakistan.

PURPOSE: Health-related quality of life (HRQoL) of pulmonary TB patients has not been assessed in Pakistan. We assessed self-reported HRQoL of pulmonary TB patients in Karachi, Pakistan utilizing the EQ-5D and EQ-VAS prior to, during, and after completion of TB treatment. METHODS: We enrolled 226 pulmonary TB patients in a longitudinal cohort study. Health-utility scores were estimated by the EQ-5D five dimensions and the EQ-Visual Analogue Scale (VAS) at baseline (month 0) and each monthly follow-up visit until treatment completion at month 6. Repeated-measures ANOVA was used to investigate effect of time into treatment on EQ-5D and EQ-VAS scores. RESULTS: EQ-5D health utility and EQ-VAS scores increase with treatment progression. For the enrolled TB patients, the mean EQ-5D utility scores more than doubled from 0.43 to 0.88, p < .001, effect size η2 = 0.40 from treatment initiation to treatment completion. CONCLUSION: Perceived HRQoL of TB patients improves with treatment progression. This can inform targeted treatment plans as well as TB policy and funding for high-burden countries.

Validity and reliability of the tuberculosis-related stigma scale version for Brazilian Portuguese.

BACKGROUND: Stigma associated with tuberculosis (TB) has been an object of interest in several regions of the world. The behaviour presented by patients as a result of social discrimination has contributed to delays in diagnosis and the abandonment of treatment, leading to an increase in the cases of TB and drug resistance. The identification of populations affected by stigma and its measurement can be assessed with the use of valid and reliable instruments developed or adapted to the target culture. This aim of this study was to analyse the initial psychometric properties of the Tuberculosis-Related Stigma scale in Brazil, for TB patients. METHODS: The Tuberculosis-Related Stigma scale is a specific scale for measuring stigma associated with TB, originally validated in Thailand. It presents two dimensions to be assessed, namely Community perspectives toward tuberculosis and Patient perspectives toward tuberculosis. The first has 11 items regarding the behaviour of the community in relation to TB, and the second is made up of 12 items related to feelings such as fear, guilt and sorrow in coping with the disease. A pilot test was conducted with 83 TB patients, in order to obtain the initial psychometric properties of the scale in the Brazilian Portuguese version, enabling simulation of the field study. RESULTS: As regards its psychometric properties, the scale presented acceptable internal consistency for its dimensions, with values ≥0.70, the absence of floor and ceiling effects, which is favourable for the property of scale responsiveness, satisfactory converging validity for both dimensions, with values over 0.30 for initial studies, and diverging validity, with adjustment values different from 100%. CONCLUSION: The results found show that the Tuberculosis-Related Stigma scale can be a valid and reliable instrument for the Brazilian context.

Predictors of delayed care seeking for tuberculosis in southern India: an observational study.

BACKGROUND: Reducing delay to accessing care is necessary to reduce the Tuberculosis (TB) burden in high incidence countries such as India. This study aimed to identify factors associated with delays in seeking care for TB in Southern India. METHODS: We analyzed data from newly diagnosed, smear-positive, culture-confirmed, pulmonary TB patients in the Regional Prospective Observational Research for TB (RePORT) cohort in Puducherry and Tamil Nadu, India. Data were collected on demographic characteristics, symptom duration, and TB knowledge, among other factors. Delay was defined as cough ≥4 weeks before treatment initiation. Risky alcohol use was defined by the AUDIT-C score which incorporates information about regular alcohol use and binge drinking. TB knowledge was assessed by knowing transmission mode or potential curability. RESULTS: Of 501 TB patients, 369 (73.7%) subjects delayed seeking care. In multivariable analysis, risky alcohol use was significantly associated with delay (aOR 2.20, 95% CI: 1.31, 3.68). Delay was less likely in lower versus higher income groups (<3000 versus >10,000 rupees/month, aOR 0.31, 95% CI: 0.12, 0.78). TB knowledge was not significantly associated with delay. CONCLUSIONS: Local TB programs should consider that risky alcohol users may delay seeking care for TB. Further studies will be needed to determine why patients with higher income delay in seeking care.

Perceived stigma and depression in initially diagnosed pulmonary tuberculosis patients.

AIMS AND OBJECTIVES: To investigate the status of tuberculosis stigma and depression among tuberculosis patients, to examine the relationship between demographics and tuberculosis stigma and depression among tuberculosis patients, and to identify the predictors of depression among tuberculosis patients. BACKGROUND: After the diagnosis of tuberculosis, patients suffer from disease symptoms and disease-related stigma. Depression is also a major concern in tuberculosis patients. DESIGN: A cross-sectional design was used in this study. METHODS: A total of 84 subjects, obtained through convenience sampling, enrolled in this study, which was conducted from 1 March 2013-30 December 2014. Data were collected using a structured questionnaire with a demographic component, the Tuberculosis-related Stigma Scale, and the Beck Depression Inventory-II. Data were analysed, using spss Version 20. Independent t tests, Pearson's correlation coefficient tests and analyses of variance were used for analysis of patient demographic characteristics, disease characteristics, and the correlation between stigma and depression. Multiple linear regression was used for determining the predictors of depression. RESULTS: The results showed that not disclosing one's illness to others was associated with tuberculosis stigma and depression. Multiple linear regression analysis indicated that patient-perceived tuberculosis stigma and body mass index accounted for 34% of the variation in depression. CONCLUSIONS: These results can serve as a reference for clinical healthcare providers to understand perceived stigma and depression in initially diagnosed tuberculosis patients. RELEVANCE TO CLINICAL PRACTICE: An intervention to reduce patient tuberculosis stigma, such as improving community healthcare education or offering mental health outreach, has great potential to lower the level of depression among patients with tuberculosis.

The experiences of high school students with pulmonary tuberculosis in China: a qualitative study.

BACKGROUND: Clustered tuberculosis (TB) still occurred nationally in Chinese schools every year, where high school students patients accounts for the highest proportion. These young TB patients are in a critical period of physical and psychological growth. Research on their illness experience and analysis of underlying causes remains blank. The purpose of this study is to explore the overall illness experience of Chinese high school TB patients and to investigate the individual and social causes of such experience. METHODS: Twenty-two high school TB patients in a certain county of Shaanxi province were interviewed in-depth twice when initial diagnosed and during intermediate treatment periods. Interview data were analyzed by framework approach. RESULTS: The high school TB patients worried about interruption of studies rather than the disease. They generally showed a lack of awareness of tuberculosis, were highly dependent on parents, and received assistance from teachers and students during the treatment. Most of them did not show obvious stigma. CONCLUSION: The unique education system and sociocultural factors in China are the root of special illness experience of high school TB patients. Huge pressure in college entrance examination leads sick students to worry about interruption of studies more than the disease itself. Their serious lack of awareness of TB, caused by the ignorance of school, parents and the students, becomes the biggest obstacle to timely diagnosis and treatment. Whether high dependence on parents is conducive to disease recovery varies with each individual. Meanwhile, patients' weak stigma could play a positive role in disease recovery. Educational and medical institutions should develop more effective TB control strategies based on these factors.

Health-related quality of life and its association with medication adherence in active pulmonary tuberculosis- a systematic review of global literature with focus on South Africa.

INTRODUCTION: Tuberculosis (TB) is a leading cause of morbidity and mortality in South Africa. Clinical parameters are important objective outcomes in TB; however they often are not directly correlated with subjective well-being of the patient, but can be assessed using patient-reported outcome (PRO) measures. Health-related quality of life (HRQOL) is a specific PRO generally multi-dimensional in nature and includes physical, mental and social health domains. The inclusion of HRQOL PROs in trials and clinical practice can provide additional information beyondclinical and microbiological parameters. Furthermore, HRQOL may be associated with medication adherence. This review focuses on patient-reported HRQOL and its association with medication adherence in TB patients in South Africa. METHODS: A comprehensive search strategy was developed focusing on the impact of TB on patient-reported HRQOL,the existence of a conceptual framework of TB-specific HRQOL, determinants of medication adherence and the association of HRQOL with medication adherence. Data were extracted from all identified articles and additionaldata extraction was performed by two independent reviewers with special focus on longitudinal studies in order to understand changes of HRQOL and adherence over time. Research gaps were identified with regard to patient-reported HRQOL and medication adherence. RESULTS: A total of 66 articles met the eligibility criteria. Ten HRQOL studies and one adherence study used a longitudinal design, none of these in South Africa. A variety of different generic and disease-specific HRQOL measures were identified in the articles. In South Africa four HRQOL and five adherence studies (non-longitudinal) were published. Similar factors (socio-demographic, socio-economic, disease-related, therapy-related and psycho-social aspects) affect HRQOL and adherence. Although standard TB treatment improved all health domains, psychological well-being and social functioning remained impaired in microbiologically cured patients after treatment. CONCLUSION: While evidence of TB impact on HRQOL and medication adherence and their association exists, it is verylimited for the South African situation. No valid and reliable TB-specific HRQOL measures were identified in this systematicreview. An assessment of HRQOL in TB patients in South Africa is required as this may assist with improving current disease management programmes, medication adherence and national treatment guidelines.

Serial survey shows community intervention may contribute to increase in knowledge of Tuberculosis in 30 districts of India.

BACKGROUND: Correct knowledge about Tuberculosis (TB) is essential for appropriate healthcare seeking behaviour and to accessing diagnosis and treatment services timely. There are several factors influencing knowledge about TB. The present study was conducted to assess the change in community knowledge of Tuberculosis (TB) and its association with respondent's socio-demographic characteristics in two serial knowledge-attitude-practice surveys. METHODS: Community level interventions including community meetings with youth groups, village health committees and self-help groups and through mass media activities were undertaken to create awareness and knowledge about TB and service availability. Increase in knowledge on TB and its association with respondent's socio-demographic characteristics was assessed by two serial KAP surveys in 2010-2011 (baseline) and 2012-2013 (midline) in 30 districts of India. Correct knowledge of TB was assessed by using lead questions and scores were assigned. The composite score was dichotomized into two groups (score 0-6, poor TB knowledge and score 7-13, good TB knowledge). RESULTS: In baseline and midline survey, 4562 and 4808 individuals were interviewed. The correct knowledge about TB; cough ≥2 weeks, transmission through air, 6-8 months treatment duration, and free treatment increased by 7 % (p-value <0.05), 11 % (p-value <0.05), 2 % (p-value <0.05), and 8 % (p-value <0.05) in midline compared to baseline, respectively. The knowledge on sputum smear test for diagnosis of TB was 66 % in both surveys while knowledge on availability of free treatment and that TB is curable disease decreased by 5 % and 2 % in midline (p-0.001), compared to baseline, respectively. The mean score for correct knowledge about TB increased from 60 % in baseline to 71 % in midline which is a 11 % increase (p-value <0.001). The misconception regarding on transmission of TB by- sharing of food and clothes and handshake persisted in midline. Respondents residing in northern (OR, 2.2, 95 % CI, 1.7-2.6) and western districts (OR, 3.4, 95 % CI, 2.7-4.1) of India and age groups- 25-34 years (OR, 1.3; 95 % CI, 1.1-1.6) and 45-44 years (OR, 1.4; 95 % CI, 1.1-1.7)- were independently associated with good TB knowledge. CONCLUSIONS: The knowledge about TB has increased over a period of 2 years and this may be attributable to the community intervention in 30 districts of India. The study offers valuable lesson for designing TB related awareness programmes in India and in other high burden countries.
