Knowledge, attitudes and practices of private sector providers of tuberculosis care: a scoping review

Engagement of private health care facilities in TB management in Lusaka district of Zambia: lessons learned and achievements

BACKGROUND

Globally, at least 3 million TB patients are missed every year. In Zambia, the TB treatment coverage increased from 66% in 2020 to 92% in 2022. Involvement of all levels of health care service delivery is critical to finding all the missing TB patients.

METHODS

A survey was undertaken in 15 private facilities in Lusaka district of Zambia using a structured tool administered by project team and a district health team member. Data collected during the survey was analysed and results were used to determine the type of TB services that were offered as well as barriers and enablers to TB service provision. This was followed by a set of interventions that included; training and mentorship on active case finding and systematic TB screening, increased diagnostic capacity, provision of national recording and reporting tools and provision of TB medication through linkage with the National TB program (NTP). We report findings from the baseline survey and changes in presumptive TB identification and notification following interventions.

RESULTS

Major barriers to TB service delivery were the high cost of TB diagnostic testing and treatment in facilities where services were not supported by the National TB program; the mean cost was 33 (SD 33) and 93 (SD 148) for GeneXpert testing and a full course of treatment respectively. Pre-intervention, presumptive TB identification appeared to increase monthly by 4 (P = 0.000, CI=[3.00-5.00]). The monthly trends of presumptive TB identification during the intervention period increased by 5.32 (P = 0.000, [CI 4.31-6.33. Pre-intervention, the notification of TB appeared to decrease every month by -4.0 (P = 0.114, CI=[-9.00-0.10]) followed by an immediate increase in notifications of 13.94 TB patients (P = 0.001, CI [6.51, 21.36] in the first month on intervention. The monthly trends of notification during the intervention period changed by 0.34 (P = 0.000 [CI 0.19-0.48]). Private facility contribution to TB notification increased from 3 to 7%.

CONCLUSION

Engagement and inclusion of private health facilities in TB service provision through a systems strengthening approach can increase contribution to TB notification by private health facilities.

Knowledge and Practices toward Tuberculosis Case Identification among Accredited Drug Dispensing Outlets Dispensers in Magu District, Northwestern Tanzania

Accredited Drug Dispensing Outlets dispensers (ADDO dispensers) have a crucial role in detecting and referring TB suspects. However, several studies highlight low knowledge of TB among ADDO dispensers. To facilitate this, the National TB and Leprosy Control Program trained ADDO dispensers on case identification and referral. Hence, this was a community-based cross-sectional study to determine the knowledge and practice of ADDO dispensers in the detection of active tuberculosis suspects in Magu Districts, Mwanza, Tanzania. This was a cross-sectional study that included 133 systematically selected ADDO dispensers. Out of 133 ADDO dispensers, 88 (66.9%) had attended TB training. About 108 (81%) participants had good knowledge of TB. The majority of ADDO dispensers 104 (78.4%) had poor practice toward the identification of TB cases. Attending training (AOR 4.49, CI 1.03-19.47), longer working experience (AOR 4.64, CI 1.99-10.81), and the presence of national TB guidelines (AOR 3.85, CI 1.11-13.34) was significantly associated with good self-reported TB case identification practices. Therefore, the study revealed adequate knowledge but with poor practice. Provisions to train ADDO dispensers in tuberculosis case detection and referral could yield great results.

Exploring the role of the private sector in tuberculosis detection and management in Lima, Peru: a mixed-methods patient pathway analysis

In Latin America, little is known about the involvement of private healthcare providers in TB detection and management. We sought to gain a better understanding of current and potential roles of the private sector in delivering TB services in Peru. We conducted a mixed-methods study in Lima, Peru. The quantitative component comprised a patient pathway analysis assessing the alignment of TB services with patient care-seeking behavior. The qualitative component comprised in-depth interviews with 18 private healthcare providers and 5 key informants. We estimated that 77% of patients initially sought care at a facility with TB diagnostic capacity and 59% at a facility with TB treatment capacity. The lack of TB services at initial care-seeking location was driven by the 41% of patients estimated to seek care first at a private facility. Among private facilities, 43% offered smear microscopy, 13% offered radiography, and none provided TB treatment. Among public sector facilities, 100% offered smear microscopy, 26% offered radiography, and 99% provided TB treatment. Interviews revealed that private providers believed that they offered shorter wait times and a quicker diagnosis, but they struggled with a lack of follow-up systems and communication barriers with the public sector. While expressing willingness to collaborate with public sector programs for diagnosis and referral, private providers had limited interest in treating TB. This study highlights the role of private providers in Peru as an entry point for TB care. Public-private collaboration is necessary to harness the potential of the private sector as an ally for early diagnosis.

Challenges in engaging the private sector for tuberculosis prevention and care in Nigeria: a mixed methods study

OBJECTIVES

This study aimed to assess the practices of private practitioners regarding tuberculosis (TB), and to ascertain factors related to the low contribution of private healthcare providers to TB prevention and care in Nigeria.

DESIGN

This is a mixed methods study comprising a quantitative retrospective review and qualitative study.

SETTING

Private health facilities (HF) in Oyo State and the Federal Capital Territory (FCT), Nigeria.

PARTICIPANTS

We used routinely collected data on patients with tuberculosis (TB) notified between 1 January 2017 and 31 December 2018. In-depth interviews were also conducted with the clinical staff of the facilities.

PRIMARY AND SECONDARY OUTCOME MEASURES

The study outcomes are practices of TB case notification and treatment outcome, as well as the barriers and enablers of TB notification.

RESULTS

A total of 13 (11.0%) out of 118 private HF were designated as 'engaged' TB care facilities in Oyo State and none (0%) of the 198 private HF in the FCT held this designation. From the 214 patients with presumptive TB, 75 (35%) were diagnosed with TB, 42 (56%) had a bacteriological test done, 12 (16%) had an X-ray of the chest alone and 21 (28%) had other non-specific investigations. Most patients diagnosed were referred to a public HF, while 19 (25%) patients were managed at the private HF. Among them, 2 (10.5%) patients were treated with unconventional regimens, 4 (21%) were cured, 2 (11%) died, 3 (16%) lost to follow-up and 10 (53%) were not evaluated. The general practitioners did not have up-to-date knowledge of TB with a majority not trained on TB. Most referred patients with presumptive and confirmed TB to the public sector without feedback and were unclear regarding diagnostic algorithm and relevant tests to confirm TB.

CONCLUSION

Most private facilities were not engaged to provide TB services although with knowledge and practice gaps. The study has been used to develop plans for strategic engagement of the private sector in Nigeria.

Health Care Providers' Knowledge of Tuberculosis and Diabetes Mellitus Comorbidity in Lubumbashi, Democratic Republic of the Congo (DRC)

Background

Tuberculosis-Diabetes mellitus (TB-DM) co-morbidity is a growing scourge in the world. The new approaches and interventions for TB control implemented by the Tuberculosis National Control Program (TNCP) in DRC require the involvement of health care providers for their success.

Objective

The objective of this study is to assess the knowledge of health care provider on different aspects of the management of TB-DM co-morbidity and to compare this knowledge according to the health care system, the type of providers and the number of years of experience.

Methods

Cross-sectional and analytic study was conducted in 11 health care facilities in the Lubumbashi Health District, selected by reasoned choice, and an electronic questionnaire was administered to health care providers. These providers were interviewed on the different aspects of the management of the TB-DM comorbidity. The data were presented and compared in relation to knowledge about TB, DM, and TB-DM comorbidity.

Results

A total of 113 providers were interviewed, predominantly males and physicians. Questions related to knowledge about DM were better answered. Doctors compared to paramedics; tertiary-level providers compared to secondary-level providers had better responses to the different questions. There is a statistically significant correlation between the level of knowledge of TB, DM and the type of health care provider, the number of years of experience.

Conclusion

The present study shows that there are gaps in the knowledge of our health care providers and community members on the recommendations of the DRC TB guidelines (Programme AntiTuberculeux Intégré 5: PATI 5) in general and on the management of TB-DM. It is therefore important and necessary to put in place strategies to improve this level of knowledge, which will focus on the extension of the guidelines, the awareness and the training of the stakeholders involved in the control.

What are the Tuberculosis Care Practices of Informal Healthcare Providers? A Cross-Sectional Study from Eastern India

India is the highest Tuberculosis (TB) burden country, accounting for an estimated 26 % of the global burden of disease. Systematic engagement of the private sector is a cornerstone of India's National Strategic Plan (NSP) for TB elimination (2017-2025). However, Informal Healthcare Providers (IPs), who are the first point of contact for a large number of TB patients, remain significantly underutilised in the National TB Elimination Program (NTEP) of India. Non-prioritisation of IPs has also resulted in a limited understanding of their TB care practices in the community. We, therefore, undertook a descriptive study to document IPs' TB care practices, primarily focusing on their approach to screening, diagnosis, treatment, and referral. This cross-sectional study was carried out from February to March 2020 in the Birbhum District of West Bengal, India. Interviews were conducted utilising the retrospective case study method. A total 203 IPs participated who reported seeing at least one confirmed TB patient in six months prior to the study. In that duration, IPs reported interacting with an average of five suspected TB cases, two of which were later confirmed as having TB. Antibiotic use was found to be common among IPs (highest 69% during the first visit); however, they were prescribed before the patient was suspected or confirmed as having TB. We noted the practice of prolonged treatment among IPs as patients were prescribed medicines until the second follow-up visit. Referral was the preferred TB case management approach among IPs, but delayed referral was observed, with only one-third (34%) of patients being referred to higher health facilities during their first visit. This study presents important findings on IPs' TB care practices which have consequences for achieving India's National Goal of TB elimination.

A public health intervention package for increasing tuberculosis notifications from private practitioners in Bandung, Indonesia (INSTEP2): A cluster-randomised controlled trial protocol

Background. A significant proportion of tuberculosis (TB) patients globally make their initial visit for medical care to either an informal provider or a private practitioner, and many are not formally notified. Involvement of private practitioners (PPs) in a public–private mix for TB (TB-PPM) provides an opportunity for improving TB control. However, context-specific interventions beyond public–private agreements and mandatory notification are needed. In this study we will evaluate whether a tailored intervention package can increase TB notifications from PPs in Indonesia. Methods. This is a cluster-randomized trial of a multi-component public health intervention. 36 community health centre (CHC) areas will be selected as study locations and randomly allocated to intervention and control arms (1:1). PPs in the intervention areas will be identified using a mapping exercise and recruited into the study if they are eligible and consent. They will receive a tailored intervention package including in-person education about TB management along with bimonthly electronic refreshers, context-specific selection of referral pathways, and access to a TB-reporting app developed in collaboration with the National TB programme. The primary hypothesis is that the intervention package will increase the TB notification rate. The primary outcome will be measured by collecting notification data from the CHCs in intervention and control arms at the end of a 1-year observation period and comparing with the 1-year pre-intervention. The primary analysis will be intention-to-treat at the cluster level, using a generalised mixed model with repeated measures of TB notifications for 1 year pre- and 1 year post-intervention. Discussion. The results from this study will provide evidence on whether a tailored intervention package is effective in increasing the number of TB notifications, and whether the PPs refer presumptive TB cases correctly. The study results will guide policy in the development of TB-PPM in Indonesia and similar settings.

"If I've got latent TB, I would like to get rid of it": Derivation of the CARD (Constraints, Actions, Risks, and Desires) Framework informed by South African healthcare worker perspectives on latent tuberculosis treatment

BACKGROUND

Healthcare workers (HWs) have at least twice the risk of tuberculosis (TB) compared to the general population. There is growing emphasis on latent TB infection (LTBI) in high-risk populations. Yet we know little about HWs' perspectives of LTBI testing and treatment to inform implementation in high-incidence settings. We developed a qualitative networked approach to analyze HWs' perspectives on LTBI testing and treatment.

METHODS

We conducted 22 in-depth interviews with nurse and physician stakeholders, who had been recruited as part of a larger study evaluating TB transmission risk in HWs at Tygerberg Hospital, Cape Town, South Africa. We performed open coding to identify emergent themes and selective coding to identify relevant text citations. We used thematic analysis to inductively derive the CARD (Constraints, Actions, Risks, Desires) framework.

RESULTS

All HWs desired to avoid developing TB but few felt this was actionable. Despite LTBI knowledge gaps, safety and cost concerns, most HWs reported hypothetical willingness to take LTBI treatment. The CARD framework showed that desire and action related to LTBI testing and treatment was clearly framed by the interactions between constraints, administrative action, and risk. The surprise HWs described on receiving a negative LTBI (Quantiferon-Plus) result suggests LTBI testing may recalibrate HWs' perceptions regarding the futility of actions to reduce their TB risk.

CONCLUSIONS

LTBI testing and treatment are acceptable to HWs and could counteract the perceived inevitability of occupational TB infection that currently may limit risk reduction action. This should be coupled with administrative leadership and infrastructural support. The CARD analytic framework is a helpful tool for implementation scientists to understand current practices within complex health systems. Application of CARD could facilitate the development of contextually-relevant interventions to address important public health problems such as occupational TB.

In the eye of the multiple beholders: Qualitative research perspectives on studying and encouraging quality of TB care in India

This paper outlines insights qualitative research brings to the study of quality of care. It advocates understanding care as sequential, interpersonal action aimed at improving health and documenting the networks in which care occurs. It assesses the strengths and weakness of contemporary quantitative and qualitative approaches to examining quality of care for tuberculosis (TB) before outlining three qualitative research programs aimed at understanding quality of TB in India. Three case studies focus on the diagnosis level in the cascade of TB care and use qualitative research to examine the clinical use of pharmaceuticals as diagnostics, the development of diagnostic tests, and the role of care providers in the utilization of diagnostic services. They show that 1) care must be understood as part of relationships over time, 2) the presence or absence of technologies does not always imply their expected use in care, 3) physicians' provision of care is often inflected by their perceptions of patient desires, and 4) effective care is not always perfectly aligned with global health priorities. Qualitative methods with a networked perspective on care provide novel findings that can and have been used when developing quality of care improvement interventions for TB.

Study on knowledge about associated factors of Tuberculosis (TB) and TB/HIV co-infection among young adults in two districts of South Africa

South Africa ranks third among 22 high burden countries in the world. TB which remains a leading cause of death causes one in five adult deaths in South Africa. An in-depth understanding of knowledge, attitudes and practices of young people towards TB is required to implement meaningful interventions. We analysed young men and women (18-24 years)'s TB knowledge including TB/HIV coinfections, testing rates and factors associated with them. A cross sectional cluster-based household survey was conducted in two provinces. Participants completed computer-assisted self-interviews on TB knowledge, testing history and TB/HIV coinfections. A participant was regarded as knowledgeable of TB if s/he correctly answered the WHO-adopted TB knowledge questions. We built three multivariate regression models in Stata 13.0 to assess factors associated with knowing TB alone, testing alone and both knowing and testing for TB. 1955 participants were interviewed (89.9% response rate). Their median age was 20 years (IQR19-22). Sixteen percent (16.2%) of the participants were social grant recipients, 55% were enrolled in a school/college and 5% lived in substandard houses. A total of 72% had knowledge of TB, 21% underwent screening tests for TB and 14.7% knew and tested for TB. Factors associated with TB knowledge were being female, younger, a student, social grant recipient, not transacting sex and having positive attitudes towards people living with HIV (PLWH). Factors associated with TB testing were being a student, receiving a social grant, living in OR Tambo district, HIV knowledge and having a family member with TB history. Factors associated with both TB knowledge and testing were being female, a student, using the print media, living in OR Tambo district and having a family member with a TB history. The study demonstrates the importance of demographic factors (gender, economic status, family TB history, and location) and HIV factors in explaining TB knowledge and testing. We recommend extending community TB testing services to increase testing.

Self-reported tuberculosis in India: evidence from NFHS-4

This paper reports self-reported levels and socioeconomic patterns in the distribution of tuberculosis (TB) cases in India, based on information collected under the National Family Health Survey-Round 4 (NFHS-4, 2014-2015). Based on a nationally representative sample of over 600 000 households comprising of about 2.9 million individuals, we estimate a self-reported point prevalence of 304 TB cases per 100 000 population, with a higher burden evident among households with poorer wealth status and among individuals with low educational levels. About 55% of the reported TB cases sought treatment from public services, with higher public service use observed in West Bengal, Kerala and Tamil Nadu. However, more than a third of the patients from poorest groups sought treatment from private sources. Results indicate a significant proportion of the general population, including those with completed school-level education continue to have incomplete knowledge on the routes of the spread of TB infection. Social stigma, such as reluctance to disclose about a family member being infected with the disease to others, also remains high. Imminent need for appropriate policy mechanisms for involving the private sector and raising consciousness through suitable advocacy measures is re-emphasised.

Knowledge, attitudes and practices related to tuberculosis in pharmacy workers in a cross-sectional survey in El Agustino, Peru

Introduction

Although the worldwide incidence of tuberculosis (TB) is slowly decreasing, annual infection rates in Peru remain among the highest in the Americas. Pharmacies could play an important role in facilitating early detection of TB. However, the awareness, expertise and cooperation of pharmacy workers is fundamental. This study explored the TB-related knowledge, attitudes and practices of pharmacy workers in a district with one of the highest incidences of TB in Peru.

Methods

This cross-sectional study applied a questionnaire that was administered face to face using smartphones with one pharmacy worker at each of 45 randomly selected pharmacies in the El Agustino district of Lima, Peru.

Results

Participants were primarily female (78%) and had an average age of 31.3 years old (range 18–57 years old). Only 11% of participants were pharmacists with complete university training. The pharmacy workers’ knowledge was adequate; however, workers had important knowledge gaps and myths regarding prevention of TB transmission. Most pharmacy workers (77%) reported they would send a client with a history of cough for more than two weeks to a healthcare center, while 23% reported they would offer them antitussive medication or antibiotics. Almost all workers reported talking with clients about diseases and reported respiratory symptoms as one of the most common causes for consultation (60%). Most participants expressed interest in learning more about TB and expanding their involvement in the fight against TB in their community.

Conclusion

Pharmacy workers have adequate knowledge about TB. However, we identified gaps in knowledge with respect to prevention of TB transmission. Pharmacy workers commonly see patients with respiratory symptoms and some offer recommendations, including for treatment. Pharmacy workers are willing to learn more and contribute to TB control and could be a valuable asset in the control and prevention of TB in Peru. To achieve this integration of pharmacy workers into TB control and prevention, more research is needed.

Variability in distribution and use of tuberculosis diagnostic tests in Kenya: a cross-sectional survey

Background

Globally, 40% of all tuberculosis (TB) cases, 65% paediatric cases and 75% multi-drug resistant TB (MDR-TB) cases are missed due to underreporting and/or under diagnosis. A recent Kenyan TB prevalence survey found that a significant number of TB cases are being missed here. Understanding spatial distribution and patterns of use of TB diagnostic tests as per the guidelines could potentially help improve TB case detection by identifying diagnostic gaps.

Methods

We used 2015 Kenya National TB programme data to map TB case notification rates (CNR) in different counties, linked with their capacity to perform diagnostic tests (chest x-rays, smear microscopy, Xpert MTB/RIF®, culture and line probe assay). We then ran hierarchical regression models for adults and children to specifically establish determinants of use of Xpert® (as per Kenyan guidelines) with county and facility as random effects.

Results

In 2015, 82,313 TB cases were notified and 7.8% were children. The median CNR/100,000 amongst 0-14yr olds was 37.2 (IQR 20.6, 41.0) and 267.4 (IQR 202.6, 338.1) for ≥15yr olds respectively. 4.8% of child TB cases and 12.2% of adult TB cases had an Xpert® test done, with gaps in guideline adherence. There were 2,072 microscopy sites (mean microscopy density 4.46/100,000); 129 Xpert® sites (mean 0.31/100,000); two TB culture laboratories and 304 chest X-ray facilities (mean 0.74/100,000) with variability in spatial distribution across the 47 counties. Retreatment cases (i.e. failures, relapses/recurrences, defaulters) had the highest odds of getting an Xpert® test compared to new/transfer-in patients (AOR 7.81, 95% CI 7.33-8.33). Children had reduced odds of getting an Xpert® (AOR 0.41, CI 0.36-0.47). HIV-positive individuals had nearly twice the odds of getting an Xpert® test (AOR 1.82, CI 1.73-1.92). Private sector and higher-level hospitals had a tendency towards lower odds of use of Xpert®.

Conclusions

We noted under-use and gaps in guideline adherence for Xpert® especially in children. The under-use despite considerable investment undermines cost-effectiveness of Xpert®. Further research is needed to develop strategies enhancing use of diagnostics, including innovations to improve access (e.g. specimen referral) and overcoming local barriers to adoption of guidelines and technologies.

Management of tuberculosis by healthcare practitioners in Pakistan: A systematic review

OBJECTIVE

To assess the quality of tuberculosis (TB) care in Pakistan, through determining comparison of healthcare practitioners' knowledge and practices to national and international TB care guidelines.

METHODS

Studies reporting on knowledge, attitudes and practices of public and private practitioners with TB patients were selected through searching electronic databases and grey literature.

FINDINGS

Of 1458 reports, 20 full-texts were assessed, of which 11 met the eligibility and quality criteria; all studies focused on private sector care. Heterogeneity precluded meta-analysis. In 3 of 4 studies, over 50% of practitioners correctly identified a cough as the main TB symptom. However, 4 out of 6 studies showed practitioners' compliance to be low (under 50%) for the use of sputum microscopy in diagnosis. The poorest quality care occurred in the later stages of treatment, with low compliance in prescribing practices for continuation-phase care and in monitoring and recording treatment progress, the latter of which is particularly critical for treatment success.

CONCLUSION

TB care was variable and generally inadequate, with both a lack of knowledge and a small 'know-do' gap evident-practitioners did not use methods that they know they should use. A lack of recent evidence found suggests that the quality of current practices may not be fully captured and further research is needed, especially on non-allopathic, rural and public-sector contexts. Improved training of practitioners, greater availability of recommended diagnostic tools and expansion of public-private partnerships are suggestions for improving the quality of TB care in Pakistan.

Linking private, for-profit providers to public sector services for HIV and tuberculosis co-infected patients: A systematic review

Background

Tuberculosis (TB) is the leading cause of infectious disease deaths worldwide and is the leading cause of death among people with HIV. The World Health Organization (WHO) has called for collaboration between public and private healthcare providers to maximize integration of TB/HIV services and minimize costs. We systematically reviewed published models of public-private sector diagnostic and referral services for TB/HIV co-infected patients.

Methods

We searched PubMed, the Cochrane Central Register of Controlled Trials, Google Scholar, Science Direct, CINAHL and Web of Science. We included studies that discussed programs that linked private and public providers for TB/HIV concurrent diagnostic and referral services and used Review Manager (Version 5.3, 2015) for meta-analysis.

Results

We found 1,218 unduplicated potentially relevant articles and abstracts; three met our eligibility criteria. All three described public-private TB/HIV diagnostic/referral services with varying degrees of integration. In Kenya private practitioners were able to test for both TB and HIV and offer state-subsidized TB medication, but they could not provide state-subsidized antiretroviral therapy (ART) to co-infected patients. In India private practitioners not contractually engaged with the public sector offered TB/HIV services inconsistently and on a subjective basis. Those partnered with the state, however, could test for both TB and HIV and offer state-subsidized medications. In Nigeria some private providers had access to both state-subsidized medications and diagnostic tests; others required patients to pay out-of-pocket for testing and/or treatment. In a meta-analysis of the two quantitative reports, TB patients who sought care in the public sector were almost twice as likely to have been tested for HIV than TB patients who sought care in the private sector (risk ratio [RR] 1.98, 95% confidence interval [CI] 1.88–2.08). However, HIV-infected TB patients who sought care in the public sector were marginally less likely to initiate ART than TB patients who sought care from private providers (RR 0.89, 95% CI 0.78–1.03).

Conclusion

These three studies are examples of public-private TB/HIV service delivery and can potentially serve as models for integrated TB/HIV care systems. Successful public-private diagnostic and treatment services can both improve outcomes and decrease costs for patients co-infected with HIV and TB.

Comparing tuberculosis management under public and private healthcare providers: Victoria, Australia, 2002-2015

BACKGROUND

Private healthcare providers are important to tuberculosis (TB) management globally, although internationally there are reports of suboptimal management and disparities in treatment commencement in the private sector. We compared the management of TB patients receiving private versus public healthcare in Victoria, an industrialised setting with low tuberculosis (TB) incidence.

METHODS

Retrospective cohort study: 2002-2015. Private healthcare provision was included as an independent variable in several multivariate logistic and Cox proportional hazard regression models that assessed a range of outcome variables, encompassing treatment commencement delays, management and treatment outcomes.

RESULTS

Of 5106 patients, 275 (5.4%) exclusively saw private providers, and 4714 (92.32%) public. Private care was associated with a shorter delay to presentation (HR 1.36, p = 0.065, 95% CI 1.02-2.00). Private patients were less likely to have genotypic testing (OR 0.66, p = 0.009, 95% CI 0.48-0.90), those with pulmonary involvement were less likely to have a sputum smear (OR 0.52, p = 0.011, 95% CI 0.31-0.86) and provided samples were less likely to be positive (OR 0.54, p = 0.070, 95% CI 0.27-1.05). Private patients with extrapulmonary TB were less likely to have a smear sample (OR 0.7, 95% CI 0.48-0.90, p = 0.009) and radiological abnormalities (OR 0.71, p = 0.070, 95% CI 0.27-1.05). Treatment commencement delays from presentation were comparable for cases with pulmonary involvement and extrapulmonary TB, although public extrapulmonary TB patients received radiological examinations slightly earlier than private patients (HR 0.79, p = 0.043, 95% CI 0.63-0.99) and public patients with pulmonary involvement from high burden settings commenced treatment following an abnormal CXR more promptly than their private counterparts (HR 0.41, p = 0.011, 95% CI 0.21-0.81). Private patients were more likely to receive <4 first-line medications (OR 2.17, p = 0.001, 95% CI 1.36-3.46), but treatment outcomes were comparable between sectors.

CONCLUSIONS

The differences we identified are likely to reflect differing case-mix as well as clinician practice. Sputum smear status was an important covariable in our analysis; with its addition we found no significant disparity in the health-system delay to treatment commencement between sectors. Our study highlights the importance of TB programs engaging with private providers, enabling comprehensive data collection that is necessary for thorough and true comparison of TB management and optimisation of care.

Knowledge, attitudes and practices regarding tuberculosis care among health workers in Southern Mozambique

Background

Tuberculosis (TB) control is more likely to be achieved if the level of knowledge regarding TB is increased among health workers managing high-risk groups. No formal assessments regarding knowledge, attitudes and practises of health workers about TB have been published for Mozambique, a country facing challenges in the fight against TB, with a fragile health system and considerable work overload of health personnel. The main objective of the study was to determine the level of knowledge, identify attitudes and assess practices regarding TB care and control among health care workers of the district of Manhiça.

Methods

A descriptive cross-sectional study was performed through the use of a specifically designed Knowledge, Attitudes and Practices (KAP) questionnaire in the district of Manhiça, a high tuberculosis and HIV burden rural area in Southern Mozambique. In this district, 14 health care facilities service a population of approximately 160,000 people. The questionnaire took 30–45 min to administer with external assistance not permitted. The survey contained 79 questions pertaining to four different areas: demographics, TB knowledge, attitudes and practices.

Results

The study sample included 170 health care workers. The average knowledge score was 14.89 points (SD = 3.61) out of a total possible 26 points. Less than 30% of respondents had heard of Xpert MTB/RIF®. Seventy per cent agreed there was stigma associated with TB and 48.2% believed this stigma was greater than that associated with HIV. The average practice score was 3.2 out of 9 points (35.6%, SD = 2.4).

Conclusion

Health care worker’s knowledge gaps identified in this study may result in substandard patient care. Specific deficiencies in understanding existed in terms of paediatric TB and Xpert MTB/RIF® testing. The present study provides impetus for tailored TB education among health care workers from a high TB burden rural area in Southern Mozambique.

Assessing healthcare quality using routine data: evaluating the performance of the national tuberculosis programme in South Africa

OBJECTIVE

To assess the performance of healthcare facilities by means of indicators based on guidelines for clinical care of TB, which is likely a good measure of overall facility quality.

METHODS

We assessed quality of care in all public health facilities in South Africa using graphical, correlation and locally weighted kernel regression analysis of routine TB test data.

RESULTS

Facility performance falls short of national standards of care. Only 74% of patients with TB provided a second specimen for testing, 18% received follow-up testing and 14% received drug resistance testing. Only resistance testing rates improved over time, tripling between 2004 and 2011. National awareness campaigns and changes in clinical guidelines had only a transient impact on testing rates. The poorest performing facilities remained at the bottom of the rankings over the period of study.

CONCLUSION

The optimal policy strategy requires both broad-based policies and targeted resources to poor performers. This approach to assessing facility quality of care can be adapted to other contexts and also provides a low-cost method for evaluating the effectiveness of proposed interventions. Devising targeted policies based on routine data is a cost-effective way to improve the quality of public health care provided.

Surveying the Knowledge and Practices of Health Professionals in China, India, Iran, and Mexico on Treating Tuberculosis

Research evidence continues to reveal findings important for health professionals' clinical practices, yet it is not consistently disseminated to those who can use it. The resulting deficits in knowledge and service provision may be especially pronounced in low- and middle-income countries that have greater resource constraints. Tuberculosis treatment is an important area for assessing professionals' knowledge and practices because of the effectiveness of existing treatments and recognized gaps in professionals' knowledge about treatment. This study surveyed 384 health professionals in China, India, Iran, and Mexico on their knowledge and practices related to tuberculosis treatment. Few respondents correctly answered all five knowledge questions (12%) or self-reported performing all five recommended clinical practices "often or very often" (3%). Factors associated with higher knowledge scores included clinical specialization and working with researchers. Factors associated with better practices included training in the care of tuberculosis patients, being based in a hospital, trusting systematic reviews of randomized controlled double-blind trials, and reading summaries of articles, reports, and reviews. This study highlights several strategies that may prove effective in improving health professionals' knowledge and practices related to tuberculosis treatment. Facilitating interactions with researchers and training in acquiring systematic reviews may be especially helpful.

Responding to cough presentations: an interview study with Cambodian pharmacies participating in a National Tuberculosis Referral Program

RATIONALE, AIMS AND OBJECTIVES

Asia-Pacific carries a high burden of respiratory-related mortality. Timely referral and detection of tuberculosis cases optimizes patient and public health outcomes. Registered private pharmacies in Cambodia participate in a National Tuberculosis Referral Program to refer clients with cough suggestive of tuberculosis to public sector clinics for diagnosis and care. The objective of this study was to investigate clinical intentions of pharmacy staff when presented with a hypothetical case of a client with prolonged cough suggestive of tuberculosis.

METHOD

A random sample of 180 pharmacies was selected. Trained interviewers administered a hypothetical case scenario to trained pharmacy staff. Participants provided 'yes'/'no' responses to five clinical actions presented in the scenario. Actions were not mutually exclusive. Data were tabulated and compared using chi-square tests or Fisher's exact tests.

RESULTS

Overall, 156 (92%) participants would have referred the symptomatic client in the case scenario. Participants who would have referred the client were less likely to sell a cough medicine (42% vs. 100%, P < 0.001) and less likely to sell an antibiotic (19% vs. 79%, P < 0.001) than those who would not have referred the client.

CONCLUSION

Involving pharmacies in a Referral Program may have introduced concepts of appropriate clinical care when responding to clients presenting with cough suggestive of tuberculosis. However, results showed enhancing clinical competence among all referral programme participants particularly among non-referring pharmacies and those making concurrent sales of cough-related products would optimize pharmacy-initiated referral. Further research into actual clinical practices at Referral Program pharmacies would be justified.

"When Treatment Is More Challenging than the Disease": A Qualitative Study of MDR-TB Patient Retention

Background

One-fifth of the patients on multidrug-resistant tuberculosis treatment at the Drug-Resistant-TB (DR-TB) Site in Gujarat are lost-to-follow-up(LFU).

Objective

To understand patients’ and providers' perspectives on reasons for LFU and their suggestions to improve retention-in-care.

Design

Qualitative study conducted between December 2013-March 2014, including in-depth interviews with LFU patients and DOT-providers, and a focus group discussion with DR-TB site supervisors. A thematic-network analysis approach was utilised.

Results

Three sub-themes emerged: (i) Struggle with prolonged treatment; (ii) Strive against stigma and toward support; (iii) Divergent perceptions and practices. Daily injections, pill burden, DOT, migratory work, social problems, prior TB treatment, and adverse drugs effects were reported as major barriers to treatment adherence and retention-in-care by patients and providers. Some providers felt that despite their best efforts, LFU patients remain. Patient movements between private practitioners and traditional healers further influenced LFU.

Conclusion

The study points to a need for repeated patient counselling and education, improved co-ordination between various tiers of providers engaged in DR-TB care, collaboration between the public, private and traditional practitioners, and promotion of social and economic support to help patients adhere to MDR-TB treatment and avoid LFU.

How do private general practitioners manage tuberculosis cases? A survey in eight cities in Indonesia

Background

Private practitioners (PPs) in high-burden countries often provide substandard tuberculosis (TB) treatment, leading to increased risk of drug resistance and continued transmission. TB case management among PPs in Indonesia has not been investigated in recent years, despite longstanding recognition of inadequate care and substantial investment in several initiatives. This study aimed to assess case management practices of private general practitioners (GPs) in eight major cities across Indonesia.

Methods

A cross-sectional survey of private GPs was carried out simultaneously in eight cities by trained researchers between August and December 2011. We aimed for a sample size of 627 in total, and took a simple random sample of GPs from the validated local registers of GPs. Informed consent was obtained from participants prior to interview. Diagnostic and treatment practices were evaluated based on compliance with national guidelines. Descriptive statistics are presented.

Results

Of 608 eligible GPs invited to participate during the study period, 547 (89.9 %) consented and completed the interview. A low proportion of GPs (24.6–74.3 %) had heard of the International Standards for TB care (ISTC) and only 41.2–68.9 % of these GPs had participated in ISTC training. As few as 47.3 % (90 % CI: 37.6–57.0 %) of GPs reported having seen presumptive TB. The median number of cases of presumptive TB seen per month was low (0–5). The proportion of GPs who utilized smear microscopy for diagnosing presumptive adult TB ranged from 62.3 to 84.6 %. In all cities, a substantial proportion of GPs (12.0–45.5 %) prescribed second-line anti-TB drugs for treating new adult TB cases. In nearly all cities, less than half of GPs appointed a treatment observer (13.8–52.0 %).

Conclusions

The pattern of TB case management practices among private GPs in Indonesia is still not in line with the guidelines, despite longstanding awareness of the issue and considerable trialing of various interventions.

Attitudes, knowledge and practices of healthcare workers regarding occupational exposure of pulmonary tuberculosis

Background

Healthcare-associated tuberculosis (TB) has become a major occupational hazard for healthcare workers (HCWs). HCWs are inevitably exposed to TB, due to frequent interaction with patients with undiagnosed and potentially contagious TB. Whenever there is a possibility of exposure, implementation of infection prevention and control (IPC) practices is critical.

Objective

Following a high incidence of TB among HCWs at Maluti Adventist Hospital in Lesotho, a study was carried out to assess the knowledge, attitudes and practices of HCWs regarding healthcare-associated TB infection and infection controls.

Methods

This was a cross-sectional study performed in June 2011; it involved HCWs at Maluti Adventist Hospital who were involved with patients and/or sputum. Stratified sampling of 140 HCWs was performed, of whom, 129 (92.0%) took part. A self-administered, semi-structured questionnaire was used.

Results

Most respondents (89.2%) had appropriate knowledge of transmission, diagnosis and prevention of TB; however, only 22.0% of the respondents knew the appropriate method of sputum collection. All of the respondents (100.0%) were motivated and willing to implement IPC measures. A significant proportion of participants (36.4%) reported poor infection control practices, with the majority of inappropriate practices being the administrative infection controls (> 80.0%). Only 38.8% of the participants reported to be using the appropriate N-95 respirator.

Conclusion

Poor infection control practices regarding occupational TB exposure were demonstrated, the worst being the first-line administrative infection controls. Critical knowledge gaps were identified; however, there was encouraging willingness by HCWs to adapt to recommended infection control measures. Healthcare workers are inevitably exposed to TB, due to frequent interaction with patients with undiagnosed and potentially contagious TB. Implementation of infection prevention and control practices is critical whenever there is a possibility of exposure.

A clinical decision support system for integrating tuberculosis and HIV care in Kenya: a human-centered design approach

With the aim of integrating HIV and tuberculosis care in rural Kenya, a team of researchers, clinicians, and technologists used the human-centered design approach to facilitate design, development, and deployment processes of new patient-specific TB clinical decision support system for medical providers. In Kenya, approximately 1.6 million people are living with HIV and have a 20-times higher risk of dying of tuberculosis. Although tuberculosis prevention and treatment medication is widely available, proven to save lives, and prioritized by the World Health Organization, ensuring that it reaches the most vulnerable communities remains challenging. Human-centered design, used in the fields of industrial design and information technology for decades, is an approach to improving the effectiveness and impact of innovations that has been scarcely used in the health field. Using this approach, our team followed a 3-step process, involving mixed methods assessment to (1) understand the situation through the collection and analysis of site observation sessions and key informant interviews; (2) develop a new clinical decision support system through iterative prototyping, end-user engagement, and usability testing; and, (3) implement and evaluate the system across 24 clinics in rural West Kenya. Through the application of this approach, we found that human-centered design facilitated the process of digital innovation in a complex and resource-constrained context.

Experiences of the parents caring for their children during a tuberculosis outbreak in high school: a qualitative study

Background

Tuberculosis (TB) remains a serious epidemic in China. In the past five years, the number of TB infections in high school students is rising and thus high school students are becoming a high risk group of TB. Parents of children with TB have to endure high psychological pressures from the disease itself, children’s education, employment and life. The purpose of this study was to investigate the psychological pressure of parents with high school students suffering from TB.

Methods

A total of 22 parents who have been taking care of their children suffering from TB were interviewed and a framework approach was used to analyze the interviews.

Results

In our study, 21/22 parents had low levels of understanding about TB; 22/22 were under psychological stress; and 20/22 stated that their daily life was impacted on TB.

Conclusions

Parents need to be given appropriate knowledge on TB and psychological counseling. Authorities should not only implement the therapeutic measures, but also focus on solving the psychological problems of patients and their families when a similar outbreak occurs.

How well can physicians manage tuberculosis? A public-private sector comparison from Karachi, Pakistan

Background

Tuberculosis (TB) is endemic in Pakistan which ranks fifth amongst the twenty two countries designated to be highly burdened by TB according to the World Health Organization. However, there is paucity of data regarding the knowledge of diagnosis of TB and its management amongst public and private practitioners. In this study, we endeavor to identify this gap in knowledge regarding the diagnosis and management of TB between public and private doctors and the factors affecting these knowledge scores in urban Pakistan.

Methods

This cross sectional survey was conducted between June and December 2011. Doctors from public hospitals, private hospitals and private clinics scattered in all eighteen towns of Karachi were included in the study. Qualified MBBS doctors working in any specialty were eligible to participate whereas doctors working in both the public and private sectors were excluded from the study. Vignette based clinical scenarios were given to assess the knowledge score regarding the diagnosis and management of TB.

Results

A total of 196 doctors participated in the study. There was a significant difference between private and public physicians in terms of age and years of practice (p-value <0.05). Significant differences in the proportion of knowledge scores were observed between the public and private doctors and National TB Control Program trained and untrained doctors in Karachi. Factors associated with inadequate knowledge scores were being female gender [OR: 2.76 (95% CI: 1.418-5.384)], private employment status [OR: 1.50 (95% CI: 1.258-2.439)], and not trained by NTP [OR: 2.98 (95% CI: 1.286-3.225)] on multivariate logistic regression analysis.

Conclusion

It is concluded that a knowledge gap exists between the public and private doctors in Karachi. Strengthening of currently implemented public private mix model along with improvement in the trainings of public and private practitioners is highly recommended to control TB in Pakistan.

Stakeholder Perceptions of a Pharmacy-Initiated Tuberculosis Referral Program in Cambodia, 2005-2012

Intensifying detection of tuberculosis (TB) symptomatic patients is a priority for Cambodia’s National Tuberculosis Program, in a country where two-thirds of the population has latent TB infection. In 2005, the National Tuberculosis Program initiated a public-private mix (PPM) collaborative program with external and local stakeholders to identify and refer persons with TB symptoms from private sector pharmacies to public sector clinics for diagnosis and treatment. This qualitative study conducted in-depth interviews with organizational stakeholders to assess their perceptions of PPM program collaboration and its sustainability in the long term. Results showed that stakeholders perceived that collaboration and efficient management had contributed to positive program performance. However, stakeholders expressed anxiety over program sustainability should external resources be reduced. Recent developments in pharmacy undergraduate education and recognition of pharmacy providers’ contribution to public health interventions may challenge PPM stakeholders to shift the paradigm from dependence on external agencies to confidence in local expertise and infrastructure.
