Direct and indirect costs of home healthcare in Japan: A cross‐sectional study

To tackle the rising healthcare expenditure in an ageing society in Japan, home healthcare has been promoted over the past several years. However, there is a dearth of literature on total costs incurring for home healthcare. In this study, we conducted a cross‐sectional study among patients, who received home healthcare in the month of May, 2018. Direct healthcare costs and patients’ clinical characteristics were collected from medical records and long‐term care databases (n = 166). Indirect costs were estimated using a questionnaire survey which obtained information on job absenteeism and care time from the caregiver. A total of 112 patients responded to the survey. The median age was 82 years (interquartile range: 74–88). Total per‐person per month home‐care costs averaged USD 6,163 with direct costs (USD 2,547) and indirect costs (USD 3,596) accounted for 41.3% and 58.3% of the total costs, respectively. The largest components of direct costs were long‐term care costs (48%) and medical costs (47%). Multivariable adjusted model showed that those with heavy healthcare were more likely to incur higher total as well as direct and indirect home healthcare cost (p75 years (p = .041) were less likely and those who used oxygen at home were more likely to incur direct home healthcare cost (p = .001) than their counterpart. Our study findings show that indirect cost is a major contributor to total home healthcare costs in Japan. Also for patients who need heavy healthcare, both direct and indirect costs are large burden.
