Using a theory of change in monitoring, evaluating and steering scale-up of a district-level health management strengthening intervention in Ghana, Malawi, and Uganda - lessons from the PERFORM2Scale consortium.

BACKGROUND: Since 2017, PERFORM2Scale, a research consortium with partners from seven countries in Africa and Europe, has steered the implementation and scale-up of a district-level health management strengthening intervention in Ghana, Malawi and Uganda. This article presents PERFORM2Scale's theory of change (ToC) and reflections upon and adaptations of the ToC over time. The article aims to contribute to understanding the benefits and challenges of using a ToC-based approach for monitoring and evaluating the scale-up of health system strengthening interventions, because there is limited documentation of this in the literature. METHODS: The consortium held annual ToC reflections that entailed multiple participatory methods, including individual scoring exercises, country and consortium-wide group discussions and visualizations. The reflections were captured in detailed annual reports, on which this article is based. RESULTS: The PERFORM2Scale ToC describes how the management strengthening intervention, which targets district health management teams, was expected to improve health workforce performance and service delivery at scale, and which assumptions were instrumental to track over time. The annual ToC reflections proved valuable in gaining a nuanced understanding of how change did (and did not) happen. This helped in strategizing on actions to further steer the scale-up the intervention. It also led to adaptations of the ToC over time. Based on the annual reflections, these actions and adaptations related to: assessing the scalability of the intervention, documentation and dissemination of evidence about the effects of the intervention, understanding power relationships between key stakeholders, the importance of developing and monitoring a scale-up strategy and identification of opportunities to integrate (parts of) the intervention into existing structures and strategies. CONCLUSIONS: PERFORM2Scale's experience provides lessons for using ToCs to monitor and evaluate the scale-up of health system strengthening interventions. ToCs can help in establishing a common vision on intervention scale-up. ToC-based approaches should include a variety of stakeholders and require their continued commitment to reflection and learning on intervention implementation and scale-up. ToC-based approaches can help in adapting interventions as well as scale-up processes to be in tune with contextual changes and stakeholders involved, to potentially increase chances for successful scale-up.

Assessing the scalability of a health management-strengthening intervention at the district level: a qualitative study in Ghana, Malawi and Uganda.

BACKGROUND: The scale-up of successfully tested public health interventions is critical to achieving universal health coverage. To ensure optimal use of resources, assessment of the scalability of an intervention is recognized as a crucial step in the scale-up process. This study assessed the scalability of a tested health management-strengthening intervention (MSI) at the district level in Ghana, Malawi and Uganda. METHODS: Qualitative interviews were conducted with intervention users (district health management teams, DHMTs) and implementers of the scale-up of the intervention (national-level actors) in Ghana, Malawi and Uganda, before and 1 year after the scale-up had started. To assess the scalability of the intervention, the CORRECT criteria from WHO/ExpandNet were used during analysis. RESULTS: The MSI was seen as credible, as regional- and national-level Ministry of Health officials were championing the intervention. While documented evidence on intervention effectiveness was limited, district- and national-level stakeholders seemed to be convinced of the value of the intervention. This was based on its observed positive results regarding management competencies, teamwork and specific aspects of health workforce performance and service delivery. The perceived need for strengthening of management capacity and service delivery showed the relevance of the intervention, and relative advantages of the intervention were its participatory and sustainable nature. Turnover within the DHMTs and limited (initial) management capacity were factors complicating implementation. The intervention was not contested and was seen as compatible with (policy) priorities at the national level. CONCLUSION: We conclude that the MSI is scalable. However, to enhance its scalability, certain aspects should be adapted to better fit the context in which the intervention is being scaled up. Greater involvement of regional and national actors alongside improved documentation of results of the intervention can facilitate scale-up. Continuous assessment of the scalability of the intervention with all stakeholders involved is necessary, as context, stakeholders and priorities may change. Therefore, adaptations of the intervention might be required. The assessment of scalability, preferably as part of the monitoring of a scale-up strategy, enables critical reflections on next steps to make the intervention more scalable and the scale-up more successful.

Access to health care for people with disabilities in rural Malawi: what are the barriers?

BACKGROUND: People with disabilities experience significant health inequalities. In Malawi, where most individuals live in low-income rural settings, many of these inequalities are exacerbated by restricted access to health care services. This qualitative study explores the barriers to health care access experienced by individuals with a mobility or sensory impairment, or both, living in rural villages in Dowa district, central Malawi. In addition, the impact of a chronic lung condition, alongside a mobility or sensory impairment, on health care accessibility is explored. METHODS: Using data from survey responses obtained through the Research for Equity And Community Health (REACH) Trust's randomised control trial in Malawi, 12 adult participants, with scores of either 3 or 4 in the Washington Group Short Set (WGSS) questions, were recruited. The WGSS questions concern a person's ability in core functional domains (including seeing, hearing and moving), and a score of 3 indicates 'a lot of difficulty' whilst 4 means 'cannot do at all'. People with cognitive impairments were not included in this study. All who were selected for the study participated in an individual in-depth interview and full recordings of these were then transcribed and translated. RESULTS: Through thematic analysis of the transcripts, three main barriers to timely and adequate health care were identified: 1) Cost of transport, drugs and services, 2) Insufficient health care resources, and 3) Dependence on others. Attitudinal factors were explored and, whilst unfavourable health seeking behaviour was found to act as an access barrier for some participants, community and health care workers' attitudes towards disability were not reported to influence health care accessibility in this study. CONCLUSIONS: This study finds that health care access for people with disabilities in rural Malawi is hindered by closely interconnected financial, practical and social barriers. There is a clear requirement for policy makers to consider the challenges identified here, and in similar studies, and to address them through improved social security systems and health system infrastructure, including outreach services, in a drive for equitable health care access and provision.

Direct costs of illness of patients with chronic cough in rural Malawi-Experiences from Dowa and Ntchisi districts.

INTRODUCTION: Chronic cough is a distressing symptom and a common reason for people to seek health care services. It is a symptom that can indicate underlying tuberculosis (TB) and/or chronic airways diseases (CAD) including asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis. In developing countries including Malawi, provision of diagnostic services and clinical management of CAD is rudimentary, so it is thought that patients make costly and unyielding repeated care-seeking visits. There is, however, a lack of information on cost of illness, both direct and indirect, to patients with chronic cough symptom. Such data are needed to inform policy-makers in making decisions on allocating resources for designing and developing the relevant health care services to address universal coverage programmes for CAD. This paper therefore explores health seeking costs associated with chronic cough and explores information on usage of the coping mechanisms which indicate financial hardship, such as borrowing and selling household assets. METHODS: This economic study was nested within a community-based, population-proportional cross-sectional survey of 15,795 individuals aged 15 years and above, in Dowa and Ntchisi districts. The study sought to identify individuals with symptoms of chronic airways disease whose health records documented at least one of the following diagnoses within the previous year: TB, Asthma, COPD, Bronchitis and Lower Respiratory Tract Infection (LRTI). We interviewed these chronic coughers to collect information on socioeconomic and socio-demographic characteristics, health care utilization, and associated costs of care in 2015. We also collected information on how they funded their health seeking costs. RESULTS: We identified 608 chronic coughers who reported costs in relation to their latest confirmed diagnosis in their hand-held health record. The mean care-seeking cost per patient was US$ 3.9 (95% CI: 3.00-5.03); 2.3 times the average per capita expenditure on health of US$ 1.69. The largest costs were due to transport (US$ 1.4), followed by drugs (US$ 1.3). The costs of non-medical inputs (US$ 2.09) was considerable (52.3%). Nearly a quarter (24.4%) of all the patients reportedly borrowed or/and sold assets/property to finance their healthcare. CCs with COPD and LRTI had 85.6% and 62.0% lower chance of incurring any costs compared with the TB patients and any patients with comorbidity had 2.9 times higher chance to incur any costs than the patients with single disease. COPD, Bronchitis and LRTI patients had 123.9%, 211.4% and 87.9% lower costs than the patients with TB. The patients with comorbidity incurred 53.9% higher costs than those with single disease. CONCLUSIONS: The costs of healthcare per chronic cougher was mainly influenced by the transport and drugs costs. Types of diseases and comorbidity led to significantly different chances of incurring costs as well as difference in magnitude of costs. The costs appeared to be unaffordable for many patients.

Health seeking for chronic lung disease in central Malawi: Adapting existing models using insights from a qualitative study.

BACKGROUND: Chronic lung diseases contribute to the growing non-communicable disease (NCD) burden and are increasing, particularly in many low and middle-income countries (LMIC) in sub-Saharan African. Early engagement with health systems in chronic lung disease management is critical to maintain quality of life and prevent further damage. Our study sought to understand health seeking behaviour in relation to chronic lung disease and TB in a rural district in Malawi. METHODS: Qualitative data was collected between March-May 2015, exploring patterns of health seeking for lung disease amongst residents of two districts in rural Malawi. Participants included those with and without lung disease, health workers and village leaders. Participants with a history of TB were included in the sample due to similarities in clinical presentation and in view of potential to cause long-term damage to lung tissue. RESULTS: Our findings are ordered around a specific model of health seeking devised by adapting previous models. The model and findings span three broad areas that were found to influence health seeking: understandings of health and disease which shaped whether, when and where to seek care; the care seeking decision which was influenced by social and structural factors; and the care seeking experience which impacted future care decisions creating 'feedback loops'. DISCUSSION: Efforts to improve effective and accessible healthcare provision for chronic lung disease need to address all the determinants of health seeking behaviour identified. This may include: enhancing the structural and financial accessibility of health services, through the strengthening of community linkages; improving communication between formal health providers, patients and communities around symptoms, diagnosis and management of chronic lung diseases; and improving the quality of diagnostic and management services through the strengthening of health systems 'hardware' (equipment availability) and 'software' (development of trusting and respectful relationships between providers and patients).

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

INTRODUCTION: The global burden of tuberculosis (TB) remains significantly high, with overreliance on biomedical interventions and inadequate exploration of the socioeconomic and cultural context of the infected population. A desired reduction in disease burden can be enhanced through a broader theoretical understanding of people's health beliefs and concerns about TB. In this qualitative study, we explore the knowledge, beliefs, and perceptions of community members and people diagnosed with TB toward TB in Ntcheu district, Malawi. METHODS: Using a qualitative phenomenological study design, data were obtained from eight focus-group discussions and 16 individual in-depth interviews. The community's experiences and perceptions of TB were captured without using any preconceived framework. Adult participants who had had or never had a diagnosis of TB were purposively selected by sex and age and enrolled for the study. Discussions and individual interviews lasting about 60 minutes each were audiotaped, transcribed, and translated into English and analyzed using MaxQDA 10 software for qualitative analysis. RESULTS: Most participants believed that TB was curable and would go for diagnosis if they had symptoms suggestive of the disease. However, based on their beliefs, individuals expressed some apprehension about the spread of TB and the social implications of being diagnosed with the disease. This perception affected participants' responses about seeking diagnosis and treatment. CONCLUSION: A supportive and collective approach consisting of a combination of mass media, interactive communication campaigns, emphasizing TB symptoms, transmission, and stigma could be useful in addressing barriers to early diagnosis and care-seeking behavior.

Community prevalence of chronic respiratory symptoms in rural Malawi: Implications for policy.

BACKGROUND: No community prevalence studies have been done on chronic respiratory symptoms of cough, wheezing and shortness of breath in adult rural populations in Malawi. Case detection rates of tuberculosis (TB) and chronic airways disease are low in resource-poor primary health care facilities. OBJECTIVE: To understand the prevalence of chronic respiratory symptoms and recorded diagnoses of TB in rural Malawian adults in order to improve case detection and management of these diseases. METHODS: A population proportional, cross-sectional study was conducted to determine the proportion of the population with chronic respiratory symptoms that had a diagnosis of tuberculosis or chronic airways disease in two rural communities in Malawi. Households were randomly selected using Google Earth Pro software. Smart phones loaded with Open Data Kit Essential software were used for data collection. Interviews were conducted with 15795 people aged 15 years and above to enquire about symptoms of chronic cough, wheeze and shortness of breath. RESULTS: Overall 3554 (22.5%) participants reported at least one of these respiratory symptoms. Cough was reported by 2933, of whom 1623 (55.3%) reported cough only and 1310 (44.7%) combined with wheeze and/or shortness of breath. Only 4.6% (164/3554) of participants with chronic respiratory symptoms had one or more of the following diagnoses in their health passports (patient held medical records): TB, asthma, bronchitis and chronic obstructive pulmonary disease). CONCLUSIONS: The high prevalence of chronic respiratory symptoms coupled with limited recorded diagnoses in patient-held medical records in these rural communities suggests a high chronic respiratory disease burden and unmet health need.

The effect of engaging unpaid informal providers on case detection and treatment initiation rates for TB and HIV in rural Malawi (Triage Plus): A cluster randomised health system intervention trial.

BACKGROUND: The poor face barriers in accessing services for tuberculosis (TB) and Human Immuno-deficiency Virus (HIV) disease. A cluster randomised trial was conducted to investigate the effectiveness of engaging unpaid informal providers (IPs) to promote access in a rural district. The intervention consisted of training unpaid IPs in TB and HIV disease recognition, sputum specimen collection, appropriate referrals, and raising community awareness. METHODS: In total, six clusters were defined in the study areas. Through a pair-matched cluster randomization process, three clusters (average cluster population = 200,714) were allocated to receive the intervention in the Early arm. Eleven months later the intervention was rolled out to the remaining three clusters (average cluster population = 209,564)-the Delayed arm. Treatment initiation rates for TB and Anti-Retroviral Therapy (ART) were the primary outcome measures. Secondary outcome measures included testing rates for TB and HIV. We report the results of the comparisons between the Early and Delayed arms over the 23 month trial period. Data were obtained from patient registers. Poisson regression models with robust standard errors were used to express the effectiveness of the intervention as incidence rate ratios (IRR). RESULTS: The Early and Delayed clusters were well matched in terms of baseline monthly mean counts and incidence rate ratios for TB and ART treatment initiation. However there were fewer testing and treatment initiation facilities in the Early clusters (TB treatment n = 2, TB testing n = 7, ART initiation n = 3, HIV testing n = 20) than in the Delayed clusters (TB treatment n = 4, TB testing n = 9, ART initiation n = 6, HIV testing n = 18). Overall there were more HIV testing and treatment centres than TB testing and treatment centres. The IRR was 1.18 (95% CI: 0.903-1.533; p = 0.112) for TB treatment initiation and 1.347 (CI:1.00-1.694; p = 0.049) for ART initiation in the first 12 months and the IRR were 0.552 (95% CI:0.397-0.767; p<0.001) and 0.924 (95% CI: 0.369-2.309, p = 0.863) for TB and ART treatment initiations respectively for the last 11 months. The IRR were 1.152 (95% CI:1.009-1.359, p = 0.003) and 1.61 (95% CI:1.385-1.869, p<0.001) for TB and HIV testing uptake respectively in the first 12 months. The IRR was 0.659 (95% CI:0.441-0.983; p = 0.023) for TB testing uptake for the last 11 months. CONCLUSIONS: We conclude that engagement of unpaid IPs increased TB and HIV testing rates and also increased ART initiation. However, for these providers to be effective in promoting TB treatment initiation, numbers of sites offering TB testing and treatment initiation in rural areas should be increased.

The economic burden of chronic non-communicable diseases in rural Malawi: an observational study.

BACKGROUND: Evidence from population-based studies on the economic burden imposed by chronic non-communicable diseases (CNCDs) is still sparse in Sub-Saharan Africa. Our study aimed to fill this existing gap in knowledge by estimating both the household direct, indirect, and total costs incurred due to CNCDs and the economic burden households bear as a result of these costs in Malawi. METHODS: The study used data from the first round of a longitudinal household health survey conducted in 2012 in three rural districts in Malawi. A cost-of-illness method was applied to estimate the economic burden of CNCDs. Indicators of catastrophic spending and impoverishment were used to estimate the economic burden imposed by CNCDs on households. RESULTS: A total 475 out of 5643 interviewed individuals reported suffering from CNCDs. Mean total costs of all reported CNCDs were 1,040.82 MWK, of which 56.8 % was contributed by direct costs. Individuals affected by chronic cardiovascular conditions and chronic neuropsychiatric conditions bore the highest levels of direct, indirect, and total costs. Using a threshold of 10 % of household non-food expenditure, 21.3 % of all households with at least one household member reporting a CNCD and seeking care for such a condition incurred catastrophic spending due to CNCDs. The poorest households were more likely to incur catastrophic spending due to CNCDs. An additional 1.7 % of households reporting a CNCD fell under the international poverty line once considering direct costs due to CNCDs. CONCLUSION: Our study showed that the economic burden of CNCDs is high, causes catastrophic spending, and aggravates poverty in rural Malawi, a country where in principle basic care for CNCDs should be offered free of charge at point of use through the provision of an Essential Health Package (EHP). Our findings further indicated that particularly high direct, indirect, and total costs were linked to specific diagnoses, although costs were high even for conditions targeted by the EHP. Our findings point at clear gaps in coverage in the current Malawian health system and call for further investments to ensure adequate affordable care for people suffering from CNCDs.

Knowledge and perception about tuberculosis among children attending primary school in Ntcheu District, Malawi.

BACKGROUND: Knowledge and perceptions about tuberculosis (TB) can influence care-seeking behavior and adherence to treatment. Previous studies in Malawi were conducted to assess knowledge and attitudes regarding TB in adults, with limited data on knowledge in children. OBJECTIVES: This study assessed knowledge and perceptions about TB in children aged 10-14 years attending primary school in Ntcheu District, Malawi. DESIGN: A cross-sectional study was conducted in four primary schools in Ntcheu District. Data on knowledge and perception of TB were collected using a structured questionnaire. Pearson chi-square test was used to determine the association between socioeconomic factors and TB knowledge and perception. A P<0.05 was considered significant. RESULTS: The study found that the learners had high knowledge regarding the cause, spread, and TB preventive measures. Almost 90% of learners knew that TB is caused by a germ, however, a lower proportion knew about TB symptoms ie, night sweats (49%) and enlarged cervical lymph nodes (40%). We found that 68% of learners did not know the duration of anti-TB treatment. No association was found between age, learners' grade, and knowledge (P>0.05). CONCLUSION: Lack of knowledge regarding TB and gaps identified, may be due to a deficiency in the content of the school curriculum or the availability of information, education, and communication materials. This is the first study to report on knowledge and perceptions of TB among primary school learners in Malawi. These results will inform the development of relevant information, education, and communication materials to enhance awareness about TB among school going children.

A household perspective on access to health care in the context of HIV and disability: a qualitative case study from Malawi.

BACKGROUND: Equitable access to health care is a challenge in many low-income countries. The most vulnerable segments of any population face increased challenges, as their vulnerability amplifies problems of the general population. This implies a heavy burden on informal care-givers in their immediate and extended households. However, research falls short of explaining the particular challenges experienced by these individuals and households. To build an evidence base from the ground, we present a single case study to explore and understand the individual experience, to honour what is distinctive about the story, but also to use the individual story to raise questions about the larger context. METHODS: We use a single qualitative case study approach to provide an in-depth, contextual and household perspective on barriers, facilitators, and consequences of care provided to persons with disability and HIV. RESULTS: The results from this study emphasise the burden that caring for an HIV positive and disabled family member places on an already impoverished household, and the need for support, not just for the HIV positive and disabled person, but for the entire household. CONCLUSIONS: Disability and HIV do not only affect the individual, but the whole household, immediate and extended. It is crucial to consider the interconnectedness of the challenges faced by an individual and a household. Issues of health (physical and mental), disability, employment, education, infrastructure (transport/terrain) and poverty are all related and interconnected, and should be addressed as a whole in order to secure equity in health.

Factors Influencing Delayed Health Care Seeking Among Pulmonary Tuberculosis Suspects in Rural Communities in Ntcheu District, Malawi.

Delayed diagnosis and treatment of tuberculosis (TB) among individuals suspected of having TB may lead to continued transmission of Mycobacterium tuberculosis in communities, higher mortality rates, and increase in government health expenditure because of prolonged illness due to late diagnosis and treatment initiation. The study explored factors leading to delayed health care seeking among individuals living in Ntcheu District, Malawi. Two key informant interviews, 16 in-depth interviews, and three focus group discussions were conducted. Participants were aged 18 years and older and never had TB. Data were analyzed using content analysis and factors were identified: inadequate knowledge about cause and transmission of TB, low self-awareness of personal risk to TB, cultural and traditional beliefs about sources of TB, stigma, and strong belief in witchcraft as a cause of illness. The TB Control Program needs to invest in social mobilization and education of communities to mitigate early health care seeking.

Informal Health Provider and Practical Approach to Lung Health interventions to improve the detection of chronic airways disease and tuberculosis at primary care level in Malawi: study protocol for a randomised controlled trial.

BACKGROUND: In developing countries like Malawi, further investigation is rare after patients with chronic cough test negative for tuberculosis. Chronic airways disease has presentations that overlap with tuberculosis. However, chronic airways disease is often unrecognised due to a lack of diagnostic services. Within developing countries, referral systems at primary health care level are weak and patients turn to unskilled informal health providers to seek health care. Delayed diagnosis and treatment of these diseases facilitates increased severity and tuberculosis transmission. The World Health Organisation developed the Practical Approach to Lung Health strategy which has been shown to improve the management of both tuberculosis and chronic airways disease. The guidelines address the need for integrated guidelines for tuberculosis and chronic airways disease. Engaging with informal health providers has been shown to be effective in improving health services uptake. However, it is not known whether engaging community informal health providers would have a positive impact in the implementation of the Practical Approach to Lung Health strategy. We will use a cluster randomised controlled trial to determine the effect of using the two interventions to improve case detection and treatment of patients with tuberculosis and chronic airways disease. METHODS: A three-arm cluster randomised trial design will be used. A primary health centre catchment population will form a cluster, which will be randomly allocated to one of the arms. The first arm personnel will receive the Practical Approach to Lung Health strategy intervention. In addition to this strategy, the second arm personnel will receive training of informal health providers. The third arm is the control. The effect of interventions will be evaluated by community surveys. Data regarding the diagnosis and management of chronic cough will be gathered from primary health centres. DISCUSSION: This trial seeks to determine the effect of Informal Health Provider and Practical Approach to Lung Health interventions on the detection and management of chronic airways disease and tuberculosis at primary care level in Malawi. TRIAL REGISTRATION: The unique identification number for the registry is PACTR201411000910192--21 November 2014.

Integrated community case management in Malawi: an analysis of innovation and institutional characteristics for policy adoption.

In 2007, Malawi became an early adopter of integrated community case management for childhood illnesses (iCCM), a policy aimed at community-level treatment for malaria, diarrhoea and pneumonia for children below 5 years. Through a retrospective case study, this article explores critical issues in implementation that arose during policy formulation through the lens of the innovation (i.e. iCCM) and of the institutions involved in the policy process. Data analysis is founded on a documentary review and 21 in-depth stakeholder interviews across institutions in Malawi. Findings indicate that the characteristics of iCCM made it a suitable policy to address persistent challenges in child mortality, namely that ill children were not interacting with health workers on a timely basis and consequently were dying in their communities. Further, iCCM was compatible with the Malawian health system due to the ability to build on an existing community health worker cadre of health surveillance assistants (HSAs) and previous experiences with treatment provision at the community level. In terms of institutions, the Ministry of Health (MoH) demonstrated leadership in the overall policy process despite early challenges of co-ordination within the MoH. WHO, United Nations Children's Fund (UNICEF) and implementing organizations played a supportive role in their position as knowledge brokers. Greater challenges were faced in the organizational capacity of the MoH. Regulatory issues around HSA training as well as concerns around supervision and overburdening of HSAs were discussed, though not fully addressed during policy development. Similarly, the financial sustainability of iCCM, including the mechanisms for channelling funding flows, also remains an unresolved issue. This analysis highlights the role of implementation questions during policy development. Despite several outstanding concerns, the compatibility between iCCM as a policy alternative and the local context laid the foundation for Malawi's road to early adoption of iCCM.

The association between multiple sources of information and risk perceptions of tuberculosis, Ntcheu district, Malawi.

BACKGROUND: Tuberculosis (TB) is one of the main causes of death in developing countries. Awareness and perception of risk of TB could influence early detection, diagnosis and care seeking at treatment centers. However, perceptions about TB are influenced by sources of information. AIM: This study aimed to determine the association between multiple sources of information, and perceptions of risk of TB among adults aged 18-49 years. METHODS: A cross-sectional study was conducted in Ntcheu district in Malawi. A total of 121 adults were sampled in a three-stage simple random sampling technique. Data were collected using a structured questionnaire. Perceptions of risk were measured using specific statements that reflected common myths and misconceptions. Low risk perception implied a person having strong belief in myths and misconceptions about TB and high risk perception meant a person having no belief in myths or misconceptions and demonstrated understanding of the disease. RESULTS: Females were more likely to have low risk perceptions about TB compared to males (67.7% vs. 32.5%, p = 0.01). The higher the household asset index the more likely an individual had higher risk perceptions about TB (p = 0.006). The perception of risk of TB was associated with sources of information (p = 0.03). Use of both interpersonal communication and mass media was 2.8 times more likely to be associated with increased perception of risk of TB (Odds Ratio [OR] = 2.8; 95% Confidence interva1[CI]: 3.1-15. 6; p = 0.01). After adjusting for sex and asset ownership, use of interpersonal communication and mass media were more likely to be associated with higher perception of risk of TB (OR, 2.0; 95% CI: 1.65-10.72; p = 0.003) compared with interpersonal communication only (OR 1.6, 95%; CI: 1.13-8.98, p = 0.027). CONCLUSION: The study found that there was association between multiple sources of information, and higher perceptions of risk of TB among adults aged 18-49 years.

Economic evaluation of the practical approach to lung health and informal provider interventions for improving the detection of tuberculosis and chronic airways disease at primary care level in Malawi: study protocol for cost-effectiveness analysis.

BACKGROUND: Chronic airway diseases pose a big challenge to health systems in most developing countries, particularly in Sub-Saharan Africa. A diagnosis for people with chronic or persistent cough is usually delayed because of individual and health system barriers. However, delayed diagnosis and treatment facilitates further transmission, severity of disease with complications and mortality. The objective of this study is to assess the cost-effectiveness of the practical approach to lung health strategy, a patient-centred approach for diagnosis and treatment of common respiratory illnesses in primary healthcare settings, as a means of strengthening health systems to improve the quality of management of respiratory diseases. METHODS/DESIGN: Economic evaluation nested in a cluster randomised controlled trial with three arms will be performed. Measures of effectiveness and costs for all arms of the study will be obtained from the cluster randomised controlled clinical trial. The main outcome measures are a combined rate of major respiratory diseases milestones and process indicators extracted from the practical approach to lung health strategy. For analysis, descriptive as well as regression techniques will be used. A cost-effectiveness analysis will be performed according to intention-to-treat principle and from a societal perspective. Cost-effectiveness ratios will be calculated using bootstrapping techniques. DISCUSSION: We hope to demonstrate the cost-effectiveness of the practical approach to lung health and informal healthcare providers, see an improvement in patients' quality of life, achieve a reduction in the duration and occurrence of episodes and the chronicity of respiratory diseases, and are able to report a decrease in the social cost. If the practical approach to lung health and informal healthcare provider's interventions are cost-effective, they could be scaled up to all primary healthcare centres.

Out-of-pocket expenditure on chronic non-communicable diseases in sub-Saharan Africa: the case of rural Malawi.

In Sub-Saharan Africa (SSA) the disease burden of chronic non-communicable diseases (CNCDs) is rising considerably. Given weaknesses in existing financial arrangements across SSA, expenditure on CNCDs is often borne directly by patients through out-of-pocket (OOP) payments. This study explored patterns and determinants of OOP expenditure on CNCDs in Malawi. We used data from the first round of a longitudinal household health survey conducted in 2012 on a sample of 1199 households in three rural districts in Malawi. We used a two-part model to analyze determinants of OOP expenditure on CNCDs. 475 respondents reported at least one CNCD. More than 60% of the 298 individuals who reported seeking care incurred OOP expenditure. The amount of OOP expenditure on CNCDs comprised 22% of their monthly per capita household expenditure. The poorer the household, the higher proportion of their monthly per capita household expenditure was spent on CNCDs. Higher severity of disease was significantly associated with an increased likelihood of incurring OOP expenditure. Use of formal care was negatively associated with the possibility of incurring OOP expenditure. The following factors were positively associated with the amount of OOP expenditure: being female, Alomwe and household head, longer duration of disease, CNCDs targeted through active screening programs, higher socio-economic status, household head being literate, using formal care, and fewer household members living with a CNCD within a household. Our study showed that, in spite of a context where care for CNCDs should in principle be available free of charge at point of use, OOP payments impose a considerable financial burden on rural households, especially among the poorest. This suggests the existence of important gaps in financial protection in the current coverage policy.

Drug resistance of Mycobacterium tuberculosis in Malawi: a cross-sectional survey.

OBJECTIVE: To document the prevalence of multidrug resistance among people newly diagnosed with - and those retreated for - tuberculosis in Malawi. METHODS: We conducted a nationally representative survey of people with sputum-smear-positive tuberculosis between 2010 and 2011. For all consenting participants, we collected demographic and clinical data, two sputum samples and tested for human immunodeficiency virus (HIV).The samples underwent resistance testing at the Central Reference Laboratory in Lilongwe, Malawi. All Mycobacterium tuberculosis isolates found to be multidrug-resistant were retested for resistance to first-line drugs - and tested for resistance to second-line drugs - at a Supranational Tuberculosis Reference Laboratory in South Africa. FINDINGS: Overall, M. tuberculosis was isolated from 1777 (83.8%) of the 2120 smear-positive tuberculosis patients. Multidrug resistance was identified in five (0.4%) of 1196 isolates from new cases and 28 (4.8%) of 581 isolates from people undergoing retreatment. Of the 31 isolates from retreatment cases who had previously failed treatment, nine (29.0%) showed multidrug resistance. Although resistance to second-line drugs was found, no cases of extensive drug-resistant tuberculosis were detected. HIV testing of people from whom M. tuberculosis isolates were obtained showed that 577 (48.2%) of people newly diagnosed and 386 (66.4%) of people undergoing retreatment were positive. CONCLUSION: The prevalence of multidrug resistance among people with smear-positive tuberculosis was low for sub-Saharan Africa - probably reflecting the strength of Malawi's tuberculosis control programme. The relatively high prevalence of such resistance observed among those with previous treatment failure may highlight a need for a change in the national policy for retreating this subgroup of people with tuberculosis.
