BACKGROUND: To examine why people lack a regular source of ambulatorycare (RSAC) and explore whether this commonly used access measureaccurately identifies population subgroups at risk for barriersto continuity care. METHODS: Using data from a 1986 nationaltelephone survey, we performed a content analysis of subjects'verbatim reports as to why they lacked an RSAC (n = 5,748).RESULTS: The 16.4 percent of respondents who lacked an RSACgave the following reasons: 1) financial problems, 8 percent;2) local resource inaccessibility, 5 percent; 3) not wantinga regular source of ambulatory care, 61 percent; and 4) transitoryloss of their regular source of ambulatory care, 18 percent.However, some sociodemographic subgroups reported substantiallymore problems with access barriers, and these disparities wereoften not detected by the global measure, RSAC. The poor werenot more likely than the non-poor to lack an RSAC (odds ratio[OR] = 0.8; 95% confidence interval, [0.6, 1.1]), but were muchmore likely to lack an RSAC for financial reasons (OR = 5.2[2.6, 10.6]). Similarly, rural respondents were not more likelythan urban dwellers to lack an RSAC, but were more likely tolack an RSAC because of local resource inaccessibility (OR =5.8 [2.8, 11.9]). CONCLUSIONS: We conclude that the global measure,RSAC, is not an accurate indicator of whether population subgroupshave access barriers to obtaining a source of continuity care.
