Use of ambulatory health services by the near poor.

Individuals in the gray area between Medicaid eligibility and sufficient income to meet the costs of health care, the near poor, utilize health services less than other groups. As part of a study of health care behavior in an inner-city area based on a household survey of three distinct populations (HMO) members, public housing project residents, and a defined geographical area), we examined this question more thoroughly. Survey results show that the near poor had lower levels of use than Medicaid recipients when other factors were controlled. Particularly among those classified as in poor health, the near poor were more likely to be non-users and less likely to make multiple visits. However, differences in use between the near poor and the Medicaid recipients are substantially and consistently smaller for the HMO users (whose costs were covered by a special contract) than for users of a hospital outpatient department. The patterns persist for regular care received for a chronic condition but not for care sought for episodes of illness. These findings point to the special disadvantage faced by low income individuals who are not receiving Medicaid.
