Relationship between having a home doctor and outpatient utilization.

While universal insurance coverage should eliminate or substantially reduce financial and certain structural barriers to medical care, inequity in utilization of care may continue to exist. We conducted a questionnaire survey of a national random sample of 4500 Japanese age 16 or over in October, 1995. Separate analyses were conducted to predict the physician visit rates for the entire respondents (N=3395) and for those with chronic conditions (N=777). Forty-three percent of the total subjects reported an ambulatory physician visit within the past three months. About 17% of subjects with one chronic condition and 14% of those with two or more chronic conditions did not have any physician visits within recent three months. The regression model demonstrated that having a home doctor, as well as comorbidity and perceived health status, is significantly associated with outpatient visit both among all subjects (p < 0.0001) and among those with chronic conditions (p < 0.01). The Japanese health system still has unevenness in outpatient resource utilization. This mainly pertains to whether they have their own regular physician. The failure of some persons with chronic diseases to be seen requires further investigation.
