Frequent outpatient attendance among people on the governmental welfare programme in Japan: assessing both patient and supplier characteristics.

This study suggests that among recipients of public assistance who can access medical services without copayment, social isolation may be associated with frequent outpatient attendance. Private clinics may also be associated with this phenomenon. Interventions to prevent social isolation-by for example, providing health and social care in a more integrated manner-may thus be efficacious in reducing the healthcare demands of socially vulnerable individuals.
