Economic evaluation of patient costs associated with tuberculosis diagnosis and care in Solomon Islands.

BACKGROUND: Tuberculosis (TB) care can be costly for patients and their families. The End TB Strategy includes a target that zero TB affected households should experience catastrophic costs associated with TB care. Costs are catastrophic when a patient spends 20% or more of their annual household income on their TB diagnosis and care. In Solomon Islands the costs of TB care are unknown. The aim of this study was to determine the costs of TB diagnosis and care, the types of costs and the proportion of patients with catastrophic costs. METHODS: This was a nationally representative cross-sectional survey of TB patients carried out between 2017 and 2019. Patients were recruited from health care facilities, from all ten provinces in Solomon Islands. During an interview they were asked about the costs of TB diagnosis and care. These data were analysed using descriptive statistics to describe the costs overall and the proportions of different types of costs. The proportion of patients with catastrophic costs was calculated and a multivariate logistic regression was undertaken to determine factors associated with catastrophic costs. RESULTS: One hundred and eighty-three TB patients participated in the survey. They spent a mean of 716 USD (inter quartile range: 348-1217 USD) on their TB diagnosis and care. Overall, 62.1% of costs were attributable to non-medical costs, while income loss and medical costs comprised 28.5 and 9.4%, respectively. Overall, 19.7% (n = 36) of patients used savings, borrowed money, or sold assets as a financial coping mechanism. Three patients (1.6%) had health insurance. A total of 92.3% (95% CI: 88.5-96.2) experienced catastrophic costs, using the output approach. Being in the first, second or third poorest wealth quintile was significantly associated with catastrophic costs (adjusted odds ratio: 67.3, 95% CI: 15.86-489.74%, p <  0.001). CONCLUSION: The costs of TB care are catastrophic for almost all patients in Solomon Islands. The provision of TB specific social and financial protection measures from the National TB and Leprosy Programme may be needed in the short term to ameliorate these costs. In the longer term, advancement of universal health coverage and other social and financial protection measures should be pursued.

The decline of leprosy in the Republic of Korea; patterns and trends 1977-2013.

BACKGROUND: Though the World Health Organization declared the 'elimination of leprosy as public health problem' in 2000, the disease remains endemic in many countries. Current trends in incidence of infection and disease are unclear. METHODS: Data on leprosy prevalence between 1977-2013 and data on new leprosy cases detected in the Republic of Korea between 1989-2013 were analysed by age, sex, clinical types, mode of detection, family history, disability grading and geographical distribution. RESULTS: Both prevalence and incidence have declined greatly. There has been a shift to an increased proportion of multibacillary disease, and older age groups, consistent with a dramatic decrease in infection transmission in recent decades. An increase in proportion of cases with family history of disease is consistent with these declines. There is evidence that declines in infection and disease have been greater in the north of the country, as revealed in patterns by place of birth over time. Cases in immigrants now form a substantial proportion of leprosy disease in the Republic of Korea. CONCLUSIONS: Leprosy has declined dramatically in the Republic of Korea in recent decades, and transmission of M. leprae may have effectively stopped. There remains a burden of care for individuals whose disease developed in the past, and there may be some additional newly detected cases among immigrants and among older individuals who acquired autochthonous infections decades ago.
