OBJECTIVES:: Since 1999, Taiwan’s National Health Insurance Administration gradually implemented 50 integrated delivery system programs (IDS programs) for people living in remote areas. These programs integrated local health care providers with outreach services provided by contracted hospital. This study aimed to assess the impact of IDS program on the residents' accessibility to and satisfaction with health care provided in remote areas. METHODS:: A questionnaire with reference to CAHPS (consumer assessment of health plan survey) was developed first, then a interview survey to test the validity and reliability in 4 IDS program was followed. A thorough telephone survey for all IDS programs was then conducted with at least 90 sample surveyed in each IDS programs. A raking weighting method was applied to ensure the distribution of sample’s characteristics is identical to the population’s. RESULTS:: The questionnaire had acceptable reliability with the Cronbach’s α of 0.74 and 0.80 in the domain of physician’s communication and accessibility, respectively. For all 6400 respondents from 50 IDS programs, more than half of respondents living in islands didn’t know IDS program at all. Nevertheless, 81.5% of respondents indicated that they can get health care within 30 minutes, and 87.4% of them were not unsatisfied with health care they received. With regards to physician’s service and health care within their residential areas, respondents gave an average score of 7.18 and 7.23 respectively in a 0-10 scale. In general, respondents resided in mountain areas appraise their health care quality higher than those resided in island areas. CONCLUSIONS:: Taiwan’s healthcare delivery model based on integration of local health service and outreach services had achieved acceptable level of accessibility to and satisfaction with health care perceived by residents in remote areas. Nevertheless, further study should explore ambulatory-care sensitive outcome such as preventable hospitalization to ascertain the effect of IDS.
