Knowledge, beliefs, and perceptions of tuberculosis among community members in Ntcheu district, Malawi

Understanding the Spectrum and Management of Post-Tuberculosis Lung Disease: A Comprehensive Review

Post-tuberculosis lung disease (PTLD) poses a significant clinical challenge in regions with a high burden of tuberculosis (TB). This review provides a comprehensive overview of PTLD, encompassing its pathogenesis, clinical manifestations, diagnostic modalities, management strategies, long-term outcomes, and public health implications. PTLD arises from residual lung damage following TB treatment and is characterized by a spectrum of pathological changes, including fibrosis, bronchiectasis, and cavitation. Clinical presentation varies widely, from chronic cough and hemoptysis to recurrent respiratory infections, which are oftentimes a diagnostic dilemma. Radiological imaging, pulmonary function tests, and careful consideration of patient history play pivotal roles in diagnosis. Management strategies involve pharmacological interventions to alleviate symptoms and prevent disease progression, which are influenced by the extent of lung damage, comorbidities, and access to healthcare. Rehabilitation programs and surgical options are available for select cases. Prognosis is influenced by the extent of lung damage, comorbidities, and access to healthcare. Prevention efforts through a TB control program and early detection are crucial in reducing the burden of PTLD. This review stresses the importance of understanding and addressing PTLD to mitigate its impact on individuals and public health systems worldwide.

Determinants of intention to conceal tuberculosis status among family members: an analysis of seven Sub-Saharan African countries

BACKGROUND

Tuberculosis (TB) remains a significant public health burden in Sub-Saharan Africa (SSA), accounting for about 25% of global TB cases. In several communities, TB diagnosis, treatment, and control have become a critical challenge, largely due to the intention to conceal TB status among family members. It is therefore crucial to understand the factors associated with the intentions to conceal TB status among family members in SSA.

METHODS

This quantitative study utilised data from the most recent Demographic and Health Surveys (DHS). The objective was to examine the factors associated with the intention to conceal the TB status of family members. The sample consisted of 58,849 individuals aged 10 years or older from seven SSA countries. Binary logistic regression was employed to assess the associations between TB status concealment and various socio-demographic and economic variables.

RESULTS

The overall prevalence of TB status concealment intentions for the seven countries was 28.0% (95% CI: 27.6-28.4). Malawi and Eswatini accounted for the highest (47.3%) and lowest (3.0%) prevalence of TB concealment intentions respectively. TB status concealment intentions decreased with increasing age (p < 0.001). Living in rural areas was associated with lower odds of intending to conceal the TB of family members compared to living in urban areas (aOR = 0.92; p = 0.008). Higher education levels were associated with lower odds of TB status concealment intentions (aOR = 0.50; p < 0.001) compared to lower education levels. As participants wealth index increased, the odds of TB status concealment intentions decreased (aOR = 0.83; p < 0.001). Country of residence also showed significant associations with individuals in Ghana (aOR = 4.51; p < 0.001), Lesotho (aOR = 2.08; p < 0.001), Malawi (aOR = 4.10; p < 0.001), Namibia (aOR = 4.40; p < 0.001), and Sao-Tome and Principe (aOR = 5.56; p < 0.001) showing higher odds of TB status concealment intentions compared to Eswatini.

CONCLUSIONS

The findings conclude that several social determinants of health, including age, urbanicity, education, and wealth contribute to TB status concealment intentions for family members. Considering these factors is important for designing targeted interventions to improve TB control in the sample. In light of the unavailability of cultural variables in the dataset, future research can leverage qualitative approaches to conduct a more comprehensive exploration of the cultural factors linked to TB status concealment intentions in the population.

Development and validation of assessment instrument for the perception and attitude toward tuberculosis among the general population in Indonesia: a Rasch analysis of psychometric properties

Introduction

Tuberculosis (TB)-related knowledge is an important evaluation metric for health education interventions. Factor analysis is limited when used on ordinal scales and does not provide in-depth item function examinations, whereas Rasch analysis addresses these limitations and offers potential advantages such as generalizability, testing of unidimensionality, producing an ordered set of items, and identifying poorly functioning items. Therefore, this research aims to develop a reliable and valid measure of perception and attitude toward TB (PATT) for public application use Rasch Analysis.

Methods

A questionnaire-based survey was conducted on the Indonesian general population using the Google Form platform. Rasch analysis was then employed to examine the psychometric properties and develop the final items of PATT.

Results

Experts from across the TB community participated in the PATT development, producing an initial scale of 16 items. Up to 1,616 participants completed the PATT questionnaire, where 74.8% were female, and 5% had a TB history. The final unidimensional 16-item scale has an item reliability of 1.00 for the two components (perception and attitude), a person reliability index of 0.87 and 0.60, as well as a Cronbach's test reliability of 0.88 and 0.88 for perception and attitude, respectively.

Conclusion

The PATT is a unidimensional scale with good construct validity and internal consistency. It has the potential to be useful for the assessment of TB perception and attitude in research and clinical practice.

Tuberculosis preventive practices among treatment supporters in Lagos, Nigeria

Context

Tuberculosis (TB) treatment support is one of the recommended strategies to enhance treatment adherence and outcomes. Treatment supporters are at risk of contracting TB and adequate knowledge of TB and good preventive practices are required for their protection.

Aims

This study aimed at assessing the knowledge and preventive practices of TB treatment supporters at Directly Observed Treatment Short-course (DOTS) centers in Lagos Mainland Local Government Area of Lagos state, Nigeria.

Settings and Design

This cross-sectional study was conducted among 196 TB treatment supporters selected from five DOTS centers in Lagos.

Methods

Data were obtained using an adapted pretested questionnaire.

Statistical Analysis Used

Bivariate and multivariate analyses were performed to determine the factors associated with self-protection practices. A P < 0.05 was considered statistically significant.

Results

The mean age of the participants was 37.3 ± 12.1 years. More than half of the respondents were females (59.2%) and immediate family members (61.3%). Overall, 22.5% had good knowledge of TB, while 53.0% had positive attitudes toward TB. Only 26.0% adequately protected themselves from infection. The caregiver's level of education (P = 0.001) and their relationship to the patient (P = 0.001) were significantly associated with good preventive practices in bivariate analysis. Not being related to the patient was a predictor of adequate TB prevention practices (adjusted odds ratio = 2.852; P = 0.006; 95% confidence interval = 1.360-5.984).

Conclusions

This study revealed low levels of TB knowledge and fair preventive practices, especially among caregivers who are relatives. There is, therefore, a need to improve population literacy about TB and its prevention and a more focused orientation of relatives who volunteer as treatment supporters, through health education, with periodic monitoring during clinic visits, of how they prevent TB.

Perceptions, Attitudes, Experiences and Opinions of Tuberculosis Associated Stigma: A Qualitative Study of the Perspectives among the Bolgatanga Municipality People of Ghana

Tuberculosis (TB) is the tenth leading cause of death worldwide. About 1.3 million people die from TB each year, and most of them are in developing countries. The stigma associated with TB is a barrier to seeking treatment and adequate care. It causes a delay in treatment-seeking and diagnosis and thus decreases the likelihood of being cured and ultimately leads to death. The objective of this study was to explore the perceptions, attitudes, experiences, and opinions about stigma related to TB among adults infected with TB and adults who were not infected with TB. Our study was qualitative in nature. The study was conducted in the community of Bolgatanga municipality of the upper-east region of Ghana. Three focus group discussions (FGDs) were conducted; one with six TB-infected females, one with seven TB-infected males, and one with six non-TB-infected participants. Data were analyzed using qualitative content analysis and presented in pre-defined and/or emerging themes: perception about signs and symptoms observed by TB infected person, attitudes towards TB patients before and after diagnosis, reasons for stigmatization, perception about diagnostic testing, and taking the drugs. Transcripts of the discussions were read, and a list of meanings for units, codes, and themes was generated on the research question. We identified the existence of stigma associated with TB. TB-infected male patients had more autonomy in decision-making about receiving treatment and other family matters compared to female TB patients. TB-infected women suffered more economic vulnerability due to the loss of their work, and the stigma was worsened due to delayed diagnosis and treatment, and they were regarded as liabilities rather than assets. TB-infected patients became stigmatized because non-TB-infected community participants did not want to come into close contact with them. Our findings suggest heightening of advocacy, communication, social mobilization, and health education on TB in the community of Bolgatanga municipality is needed to allay TB-related stigma, especially for women.

Tuberculosis prevalence, knowledge of transmission and its association with vaccination of children

Background

Understanding the perceptions of patients regarding tuberculosis (TB) will enable better design of a comprehensive, client-oriented program for the disease.

Methods

This study was conducted district-wise across India in 2015-2016 as part of the National Family Health Surveys (NFHS).

Results

We discovered that the prevalence of TB remains significantly high, with quite a high percentage of people being unaware of the exact cause of disease proliferation. The majority of people believed that touching or sharing utensils can be a source of TB. This perception affected the participants' responses about seeking diagnosis and treatment. However, it is a good sign that most people knew that TB is a curable disease that can be prevented to some extent if immunization with the Bacillus Calmette-Guérin (BCG) vaccine is done at the correct stage. So, a large section of the population had their children vaccinated. In addition, they would go for diagnosis if they had symptoms suggestive of the disease.

Conclusion

Findings from this study are indicative of the fact that a large population is aware that health facilities can make a significant contribution to the treatment of tuberculosis. There is a need to further investigate how this information could potentially be used to enhance early seeking of appropriate services among TB patients.

"Their place is beyond the town's border": A qualitative exploration of stigma associated with tuberculosis in rural and urban areas of Lagos, Nigeria

Tuberculosis (TB) remains a major public health challenge in Nigeria with a minimum yield of various TB control efforts due to sociocultural determinants of health including TB-associated stigma. Therefore, to achieve the Sustainable Development Goal targets for TB control, an understanding and reduction in TB-associated stigma is necessary. The study aims to explore the perspective of community members and investigate the possible ways of mitigating TB-associated stigma in rural and urban areas in Lagos State, Nigeria. Eight focus group discussions (FGD) were conducted among eight homogenous groups of participants living in the community in rural and urban areas of Lagos state who were stratified by gender, between July and November 2017. Analysis of data was done using the modified grounded theory. A total of 86 participants took part in the FGDs. There were various stigmatising behaviours towards people infected with TB in rural and urban communities studied. This includes: Not willing to eat with people suffering from TB, withdrawal from TB patients in social gatherings, verbal abuse of TB patients and refusing to visit their houses because of their illness. There were also misconceptions about the cause of TB in our study which includes spiritual attack, ingestion of cat hair and inhalation of dust. However, participants in the study believed that mitigating the effect of TB-associated stigma will require adequate community education on TB, provision of financial and emotional support to the patients, as well as the involvement of community leaders in TB control activities and stigma reduction interventions. TB-associated stigma exists in rural and urban communities, with a lack of appropriate knowledge of TB and fear of infection as a major determinant in rural and urban areas respectively. Health education and sensitisation about TB, with community leaders as champions could help to mitigate the effect of TB-associated stigma.

'TB is a disease which hides in the body': Qualitative data on conceptualisations of tuberculosis recurrence among patients in Zambia and South Africa

The WHO estimates 58 million people experienced one or more TB disease episodes between 2000 and 2018. These 'former TB patients' are at greater risk of future TB infection and death than TB naïve people. Additionally, former TB patients experience social, psychological, and physiological difficulties after microbiological cure. Drawing on semi-structured interviews collected with 28 people from communities in Zambia (n = 8) and South Africa (n = 2) between October 2018 and March 2019, we describe their perceptions of having two or more TB episodes. Utilising a discursive analytic approach, we interrogated how participants conceptualise their risk of disease recurrence. Despite being surprised by subsequent TB episodes, participants utilised their bodily experiences of TB signs and symptoms alongside their experiential knowledge of health systems processes to procure timely diagnosis and care. Yet, many participants were unable to resume social and economic participation. Experiences of multiple TB episodes and correlating social, economic, and physiological vulnerabilities, challenged participants biomedical understanding of TBs curability. Through notions of dirt and 'staining', participants conceptualise TB as a sinister, malicious presence they are bound to encounter time and again. Health providers should discuss the risk of TB recurrence with patients and promote prevention, early detection, and diagnosis of TB disease.

The Effect of Javanese Language Videos with a Community Based Interactive Approach Method as an Educational Instrument for Knowledge, Perception, and Adherence amongst Tuberculosis Patients

The long period of tuberculosis treatment causes patients to have a high risk of forgetting or stopping the medication altogether, which increases the risk of oral anti-tuberculosis drug resistance. The patient’s knowledge and perception of the disease affect the patient’s adherence to treatment. This research objective was to determine the impact of educational videos in the local language on the level of knowledge, perception, and adherence of tuberculosis patients in the Regional General Hospital (RSUD) Bangil. This quasi-experimental study design with a one-month follow-up allocated 62 respondents in the intervention group and 60 in the control group. The pre- and post-experiment levels of knowledge and perception were measured with a validated set of questions. Adherence was measured by pill counts. The results showed that the intervention increases the level of knowledge of the intervention group higher than that of the control group (p-value < 0.05) and remained high after one month of follow-up. The perceptions domains that changed after education using Javanese (Ngoko) language videos with the Community Based Interactive Approach (CBIA) method were the timeline, personal control, illness coherence, and emotional representations (p-value < 0.05). More than 95% of respondents in the intervention group take 95% of their pill compared to 58% of respondents in the control group (p-value < 0.05). Utilization of the local languages for design a community-based interactive approach to educate and communicate is important and effective.

Determinants of self-reported correct knowledge about tuberculosis transmission among men and women in Malawi: evidence from a nationwide household survey

BACKGROUND

Correct knowledge about transmission of tuberculosis (TB) can influence better health-seeking behaviors, and in turn, it can aid TB prevention in society. Therefore, this study aimed to examine the prevalence and predictors of self-reported correct knowledge about TB transmission among adults in Malawi.

METHODS

We conducted a secondary analysis of the data obtained from the Malawi Demographic and Health Survey, 2015/16 (MDHS 2015/16). Questions regarding self-reported TB transmission were computed to evaluate the correct knowledge about TB transmission. The factors associated with the correct knowledge about Tb were assessed using univariate and multivariable logistic regression.

RESULTS

Overall, the prevalence of correct knowledge about TB transmission in the general population of Malawian adults was 61.5%. Specifically, the prevalence of correct knowledge about TB transmission was 63.6 and 60.8% in men and women, respectively. Those aged 35-44 years, having secondary or high education, belonging to the richest household, being exposed to mass media, being in professional/technical/managerial, having knowledge that "TB can be cured", and those living in urban areas were significantly associated with correct knowledge about TB transmission.

CONCLUSIONS

The findings of this study show that if appropriate strategies for TB communication and education to address the rural masses, young individuals, poor individuals, and individuals in the agriculture sector are put it place, can enhance TB prevention in Malawi.

Lived experiences of tuberculosis patients and their implications for early tuberculosis case identification and management in pastoralist community setting: a qualitative study in Borena zone, Oromia region of Ethiopia

BACKGROUND

Ethiopia has highly diversified population with notable socioeconomic and cultural differences. Regardless of the differences, short course directly observed treatment,where patients should take drugs under direct observasion of health care providers, is uniformly applied all over the country. Evidences are scarce on how well does this uniform approach fits with the pastoral community setting. The purpose of this study was to explore lived experiences of TB patients in the pastoral community under the uniform approach, and their implications to early case identification and management.

METHOD

Qualitative method with phenomenological study design was undertaken to explore lived experiences of TB patients. Patients from all levels of health care (hospital, health center and health post) were included. Experience of both drug susceptible and drug resistant TB patients were documented. Twenty one patients, who consented to in the study, were selected by a convenience sampling method. In-depth interview was conducted using a semi-structured interview guide and the interview ended subsequent to information saturation. The interview was audio recorded; and field notes were also taken. Data analysis was done concurrently with the data collection using a word processor designed for qualitative text analysis. InductiveThematic analysis was undertaken to identify key themes.

RESULTS

Twenty one patients (eight from hospitals, nine from health centers and four from health posts) were interviewed. Three of the eight hospital patients were on drug resistant tuberculosis (TB) treatment. Sixty two codes, five code categories and three themes emerged from the interviews. The three themes were health system, stigma and discrimination, and socioeconomic problem related experiences. Inaccessibility to health facilities due to scattered settlement and mobility, delay in care seeking TB symptoms, low index of suspecting TB by care providers, fear of stigma and indirect treatment related costs were some of the codes identified.

CONCLUSION

TB patients in the pastoral setting were experiencing multifaceted challenges with the current application of 'one-size-fits-all' approach which implied hampered timely case identification and compromised patient management. Therefore, designing context appropriate intervention approach is required to ensure unprejudiced services.

'They are inconveniencing us' - exploring how gaps in patient education and patient centred approaches interfere with TB treatment adherence: perspectives from patients and clinicians in the Free State Province, South Africa

BACKGROUND

Tuberculosis (TB) treatment loss to follow up (LTFU) plays an important contributory role to the staggering TB epidemic in South Africa. Reasons for treatment interruption are poorly understood. Treatment interruption appears to be the culmination of poor health literacy of patients and inadequate health education provided by clinicians. We explored clinician and patient perspectives of the gaps in TB messaging that influence TB treatment LTFU.

METHODS

We conducted semi-structured in-depth interviews between January and May 2018 with a sample of 15 clinicians managing TB and 7 patients identified as LTFU in public clinics in the Free State Province, South Africa. Thematic analysis using a mixed deductive/inductive thematic approach was used.

RESULTS

Limited occupational opportunities, fear of disclosure and stigmatization all contributed to treatment LTFU. Patients felt that the TB messaging received was inadequate. Many of the clinicians interviewed felt that improving patient's TB knowledge would reinforce adherence to treatment and thus focused on sharing information on treatment completion, side effects and infection control. However, the inability of clinicians to establish rapport with patients or to identify social support challenged TB treatment adherence by patients. Clinicians perceived this as patients not following their instructions despite what they considered lengthy TB education. Having said this, clinicians concurred that their medical management of TB lacked the psycho-social dimension to treat a social disease of this magnitude.

CONCLUSIONS

Limited occupational opportunities, fear of disclosure and stigmatization all contributed to treatment LTFU. Clinicians concurred that poor patient understanding of TB and that biomedical management lacking a psycho-social dimension further exacerbated the poor treatment outcome. TB remains a social disease, the successful management of which hinges on patient-centred care.

Tuberculosis-related stigma contributing to a 'hidden' disease at autopsy

A 29-year-old African immigrant to Australia was found dead in bed. She had no known medical history, except for recent weight loss and hip/leg pain. Autopsy examination revealed extensive tuberculous consolidation with widespread cavitation of the lungs, with multiple caseating granulomas containing large numbers of acid fast bacilli on histology. Similar granulomas were also present in lymph nodes of the porta hepatis, mediastinum and pulmonary hilum, and within the liver, spleen and mesentery. Mycobacterial polymerase chain reaction analysis confirmed tuberculous infection. Her serum was negative for human immunodeficiency virus infection. Death was due to disseminated tuberculosis. In many parts of Africa, there are negative cultural associations attached to tuberculosis, which often leads to a delay in diagnosis. The case demonstrates the extent of active disease that may be uncovered at autopsy in decedents from societies where tuberculosis is stigmatised and therefore concealed. It also emphasises the risk of infection for forensic workers.
