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

ABSTRACT: 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.

Project description:BackgroundThe high burden of chronic communicable diseases such as HIV/AIDS, and an escalating rise of non-communicable diseases (NCDs) in Malawi and other sub-Saharan African countries, calls for a shift in how health care services are designed and delivered. Patient-centred care and patient self-management are critical elements in chronic care, and are advocated as universal strategies. In sub-Saharan Africa, there is need for more evidence around the practice of patient self-management, and how to best support patients with chronic conditions in the African context. Our study explored self-management practices of patients with different chronic conditions, and their strategies to overcome care challenges in a resource-constrained setting in Malawi.MethodsThis is primarily a qualitative study, involving patients with different chronic conditions from one rural district in Malawi. Data are drawn from semi-structured questions of a survey with 129 patients (from the third of four-part data collection series), 14 in-depth interviews, and four focus-group discussions with patients (n = 31 respondents). A framework approach was used for qualitative analysis, and descriptive statistical analysis was performed on survey data.ResultsPatients demonstrated ability to self-manage their conditions, though this varied between conditions, and was influenced by individual and external factors. Factors included: 1) ability to acquire appropriate disease knowledge; 2) poverty level; 3) the presence of support from family caregivers and community-based support initiatives; 4) the nature of one's social relations; and 5) the ability to deal with stressors and stigma. NCD and HIV comorbid patients were more disadvantaged in their access to care, as they experienced frequent drug stock-outs and incurred additional costs when referred. These barriers contributed to delayed care, poorer treatment adherence, and likelihood of poorer treatment outcomes. Patients proved resourceful and made adjustments in the face of (multiple) care challenges.ConclusionOur findings complement other research on self-management experiences in chronically ill patients with its analysis on factors and barriers that influence patient self-management capacity in a resource-constrained setting. We recommend expanding current peer-patient and support group initiatives to patients with NCDs, and further investments in the decentralisation of integrated health services to primary care level in Malawi.

Project description:BACKGROUND:The differential sensitivity of cough to antitussive therapies implies the existence of heterogeneity in cough hypersensitivity, but how such heterogeneity is expressed across individual patients is poorly understood. We investigated the phenotypes of cough hypersensitivity by examining transient receptor potential ankyrin 1 (TRPA1)- and transient receptor potential vanilloid 1 (TRPV1)-mediated cough sensitivity in patients with chronic refractory cough. METHODS:Using a selective TRPA1 agonist, allyl isothiocyanate (AITC), we established an AITC cough challenge as a measure of TRPA1-mediated cough sensitivity. The AITC cough challenge and the widely used capsaicin (a selective TRPV1 agonist) cough challenge were performed with 250 patients with chronic refractory cough and 56 healthy subjects. The concentration of AITC or capsaicin solution causing at least two (C2) and five coughs (C5) was recorded. Cough sensitivity was expressed as the mean (95% confidence interval) of log C5, and cough hypersensitivity was defined as a log C5 value lower than that of healthy subjects. RESULTS:A distinct concentration-response effect of inhaled AITC was identified both in patients with chronic refractory cough and in healthy subjects. Cough sensitivity to AITC and capsaicin was significantly higher in patients than in healthy subjects (AITC: 2.42 [2.37-2.48] vs 2.72 [2.66-2.78] mM, p?=?0.001; capsaicin: 1.87 [1.75-1.98] vs 2.53 [2.36-2.70] ?M, p?=?0.001) and was higher in females than in males for both healthy subjects and patients (all p?<?0.05). Among the 234 patients who completed both challenges, 25 (10.7%) exhibited hypersensitivity to both AITC and capsaicin, 44 (18.8%) showed hypersensitivity to AITC only, 28 (11.9%) showed hypersensitivity to capsaicin only, and 137 (58.6%) exhibited hypersensitivity to neither. Those with TRPA1- and/or TRPV1-mediated hypersensitivity were predominantly female, while those without TRPA1- and TRPV1-mediated hypersensitivity were mainly male. CONCLUSIONS:Four phenotypes of cough hypersensitivity were identified by the activation of TRPV1 and TRPA1 channels, which supports the existence of heterogeneity in cough pathways and provides a new direction for personalized management of chronic refractory cough.
