Assessing the consequences of stigma for tuberculosis patients in urban zambia

Background Stigma is one of the many factors hindering tuberculosis (TB) control by negatively affecting hospital delay and treatment compliance. In Zambia, the morbidity and mortality due to TB remains high, despite extended public health attempts to control the epidemic and to diminish stigma. Study Aim To enhance understanding of TB-related stigmatizing perceptions and to describe TB patients’ experiences of stigma in order to point out recommendations to improve TB policy. Methods We conducted a mixed method study at Kanyama clinic and surrounding areas, in Lusaka, Zambia; structured interviews with 300 TB patients, multiple in-depth interviews with 30 TB patients and 10 biomedical health workers, 3 focus group discussions with TB patients and treatment supporters, complemented by participant observation and policy analysis of the TB control program. Predictors of stigma were identified by use of multivariate regression analyses; qualitative analysis of the in-depth interviews, focus group discussions and participant observation was used for triangulation of the study findings. Results We focused on the 138/300 patients that described TB-related perceptions and attitudes, of whom 113 (82%) reported stigma. Stigma provoking TB conceptions were associated with human immunodeficiency virus (HIV)-infection, alleged immoral behaviour, (perceived) incurability, and (traditional) myths about TB aetiology. Consequences of stigma prevailed both among children and adults and included low self-esteem, insults, ridicule, discrimination, social exclusion, and isolation leading to a decreased quality of life and social status, non-disclosure, and/or difficulties with treatment compliance and adherence. Women had significantly more stigma-related problems than men. Conclusions The findings illustrate that many TB patients faced stigma-related issues, often hindering effective TB control and suggesting that current efforts to reduce stigma are not yet optimal. The content and implementation of sensitization programs should be improved and more emphasis needs to be placed on women and children.

Effectiveness of interventions for diagnosis and treatment of tuberculosis in hard-to-reach populations in countries of low and medium tuberculosis incidence: a systematic review

Tuberculosis is over-represented in hard-to-reach (underserved) populations in high-income countries of low tuberculosis incidence. The mainstay of tuberculosis care is early detection of active tuberculosis (case finding), contact tracing, and treatment completion. We did a systematic review with a scoping component of relevant studies published between 1990 and 2015 to update and extend previous National Institute for Health and Care Excellence (NICE) reviews on the effectiveness of interventions for identifying and managing tuberculosis in hard-to-reach populations. The analyses showed that tuberculosis screening by (mobile) chest radiography improved screening coverage and tuberculosis identification, reduced diagnostic delay, and was cost-effective among several hard-to-reach populations. Sputum culture for pre-migration screening and active referral to a tuberculosis clinic improved identification. Furthermore, monetary incentives improved tuberculosis identification and management among drug users and homeless people. Enhanced case management, good cooperation between services, and directly observed therapy improved treatment outcome and compliance. Strong conclusions cannot be drawn because of the heterogeneity of evidence with regard to study population, methodology, and quality.

Barriers and facilitators to the uptake of tuberculosis diagnostic and treatment services by hard-to-reach populations in countries of low and medium tuberculosis incidence: a systematic review of qualitative literature

Tuberculosis disproportionately affects hard-to-reach populations, such as homeless people, migrants, refugees, prisoners, or drug users. These people often face challenges in accessing quality health care. We did a systematic review of the qualitative literature to identify barriers and facilitators to the uptake of tuberculosis diagnostic and treatment services by people from hard-to-reach populations in all European Union (EU), European Economic Area, EU candidate, and Organisation for Economic Co-operation and Development countries. The 12 studies included in this review mainly focused on migrants. Views on perceived susceptibility to and severity of tuberculosis varied widely and included many misconceptions. Stigma and challenges regarding access to health care were identified as barriers to tuberculosis diagnosis and treatment uptake, whereas support from nurses, family, and friends was a facilitator for treatment adherence. Further studies are required to identify barriers and facilitators to the improved identification and management of tuberculosis in hard-to-reach populations to inform recommendations for more effective tuberculosis control programmes.

Perceptions, health care seeking behaviour and implementation of a tuberculosis control programme in Lambarene Gabon

SETTING Lambaréné, Gabon. OBJECTIVES To describe patient perceptions of tuberculosis (TB) and to determine factors that influence health care seeking behaviour to gain insight into the management of multidrug-resistant TB. DESIGN Participant observation, in-depth semi-structured interviews and focus group discussions were conducted with 30 TB patients, 36 relatives, 11 health care providers and 18 traditional/spiritual healers. Recruitment of patients was linked to the PanEpi study and took place at the Albert Schweitzer Hospital, the General Hospital and the TB-HIV (human immunodeficiency virus) clinic. RESULTS Patients generally described TB as a natural and/or magical disease. The majority of the patients combined treatment at the hospital with (herbal) self-treatment and traditional/spiritual healing. Despite the free availability of anti-tuberculosis treatment in principle, patient adherence was problematic, hindering effective TB control. Most patients delayed or defaulted from treatment due to financial constraints, stigmatisation, ignorance about treatment, change of health care service or use of non-prescribed antibiotics. The situation was occasionally complicated by drug stockouts. CONCLUSION There is an urgent need to bridge the gap between patients and the hospital by avoiding drug shortages, intensifying culturally sensitive TB health education, embedding TB care into the cultural context and enhancing cooperation between hospitals, patients, traditional healers and communities.

Factors Associated with Retention to Care in an HIV Clinic in Gabon, Central Africa.

Background Retention to HIV care is vital for patients’ survival, to prevent onward transmission and emergence of drug resistance. Travelling to receive care might influence adherence. Data on the functioning of and retention to HIV care in the Central African region are limited. Methods This retrospective study reports outcomes and factors associated with retention to HIV care at a primary HIV clinic in Lambaréné, Gabon. Adult patients who presented to this clinic between January 2010 and January 2012 were included. Outcomes were retention in care (defined as documented show-up for clinical visits, regardless of delay) or LTFU (defined as a patient not retained in care; on ART or ART naïve, not returning to care during the study period with a patient delay for scheduled visits of more than 6 months), and mortality. Cox regression analysis was used to assess factors associated with respective outcomes. Qualitative data on reasons for LTFU were obtained from focus-group discussions. Results Of 223 patients included, 67.3% were female. The mean age was 40.5 (standard deviation 11.4) years and the median CD4 count 275 (interquartile range 100.5–449.5) cells/μL. In total, 34.1% were lost to follow up and 8.1% died. Documented tuberculosis was associated with increased risk of being LTFU (adjusted hazard ratio (aHR) 1.80, 95% confidence interval (95% CI) 1.05–3.11, P = 0.03), whereas early starting anti-retroviral therapy (ART) was associated with a decreased risk of LTFU (aHR 0.43, 95%CI 0.24–0.76, P = 0.004), as was confirmed by qualitative data. Conclusions Retention to HIV care in a primary clinic in Gabon is relatively poor and interventions to address this should be prioritized in the HIV program. Early initiation of ART might improve retention in care.

Echinococcosis in Tambool, Central Sudan: a knowledge, attitude and practice (KAP) study

Introduction In Sudan, echinococcosis (EC) is a chronic neglected zoonotic parasitic disease caused by Echinococcus granulosus. Studies have shown high prevalence rates in dogs (50-70%), camels (35%) and sheep, goats and cattle (10-11%). In total, 0.3-1.0% of humans in Central and South Sudan are infected with the G6 camel strain. This strain is almost exclusively the cause of human infections. The objective of this study was to explore knowledge, attitudes and practices (KAP) regarding the disease among people living around Tambool city, Central Sudan. Methods A cross-sectional survey was conducted in three villages around the city of Tambool in Central Sudan. Three-hundred-and-twelve households were selected from the administrative unit of the area for participation in the study, of which 300 agreed to partake. A standardized questionnaire was designed to collect data on EC in animals, humans and the environment. The questionnaire domains were socio-demographic characteristics, KAP regarding echinococcosis. Results The population surveyed showed that 68.7% (206/300) had never heard of the disease, while 31.3% (94/300) had heard about it. The level of knowledge among the 31.3% of those that had heard about the disease was excellent (69/94; 73.4%); so were their attitudes (76/94; 80.9%). However, the majority of the participants (64/94; 68%) showed poor practice regarding this disease, enhancing the odds for further propagation of parasite circulation in the animal and human populations at risk. Knowledge was found to be significantly associated with marital status. Practice was found to be significantly associated with occupation. Conclusions There is a need for the implementation of a multidisciplinary program using the One Health approach to effectively control and prevent EC.

Effectiveness of service models and organisational structures supporting tuberculosis identification and management in hard-to-reach populations in countries of low and medium tuberculosis incidence: a systematic review

Objective To determine which service models and organisational structures are effective and cost-effective for delivering tuberculosis (TB) services to hard-to-reach populations. Design Embase and MEDLINE (1990–2017) were searched in order to update and extend the 2011 systematic review commissioned by National Institute for Health and Care Excellence (NICE), discussing interventions targeting service models and organisational structures for the identification and management of TB in hard-to-reach populations. The NICE and Cochrane Collaboration standards were followed. Setting European Union, European Economic Area, European Union candidate countries and Organisation for Economic Co-operation and Development countries. Participants Hard-to-reach populations, including migrants, homeless people, drug users, prisoners, sex workers, people living with HIV and children within vulnerable and hard-to-reach populations. Primary and secondary outcome measures Effectiveness and cost-effectiveness of the interventions. Results From the 19 720 citations found, five new studies were identified, in addition to the six discussed in the NICE review. Community health workers from the same migrant community, street teams and peers improved TB screening uptake by providing health education, promoting TB screening and organising contact tracing. Mobile TB clinics, specialised TB clinics and improved cooperation between healthcare services can be effective at identifying and treating active TB cases and are likely to be cost-effective. No difference in treatment outcome was detected when directly observed therapy was delivered at a health clinic or at a convenient location in the community. Conclusions Although evidence is limited due to the lack of high-quality studies, interventions using peers and community health workers, mobile TB services, specialised TB clinics and improved cooperation between health services can be effective to control TB in hard-to-reach populations. Future studies should evaluate the (cost-)effectiveness of interventions on TB identification and management in hard-to-reach populations and countries should be urged to publish the outcomes of their TB control systems.

Knowledge, attitudes and practices regarding malaria in people living with HIV in rural and urban Ghana

BACKGROUND One of the malaria vulnerable groups is people living with HIV. This study investigated knowledge, attitude and practices (KAP) towards malaria in people living with HIV attending anti-retroviral therapy (ART) clinics in rural and urban Ghana. METHODS In this descriptive cross-sectional study patients attending the ART clinics in Atibie (rural area) and Accra (urban area) were interviewed on their knowledge, attitude and practices regarding malaria. Finger-prick capillary blood was tested for Plasmodium spp. with rapid diagnostic tests. Multivariate regression analysis was used to determine the influence of KAP on malaria prevalence. RESULTS Parasitemia was generally more frequent among HIV positive individuals in the rural area (29/116; 25%) in the rural area than in the urban area (35/350; 10%). Inaccurate knowledge of cause of malaria and prevention methods were associated with increased odds of malaria parasitemia; [OR = 1.51 (CI: 1.29-5.12); p < .05] and [OR = 2.59 (CI: 2.53-4.75); p < .05], respectively. There were disparities in socio-economic factors. For instance, low level of education was higher in the rural area (45/116; 38.8%) compared to the urban area (121/350; 34.6%). CONCLUSIONS Malaria control efforts may yield further results when the knowledge and socio-economic gap between rural and urban areas is closed.
