Functional status and financial barriers to medical care among the poor.

We compared the functional status of 94 poor patients with financial barriers to recommended medical care with that of 94 poor control patients without such barriers in a university-affiliated community clinic. Financial barriers existed when an insured patient's health insurance failed to cover recommended care or when an uninsured patient could not afford recommended care. Patients with financial barriers scored significantly lower than control subjects on the psychologic function/mental health component of the functional status questionnaire and tended to score lower on all other functional status measures. The results suggest that poor patients with financial barriers to recommended medical care may be sicker than other poor patients.
