ObjectivesThis study examined the relationship between claims-based and patient-reported continuity of care (COC) measures and investigated the effects of the 2 types of COC measures on subjective and objective health care outcomes.Study DesignA prospective, cross-sectional, correlational survey design was used. A nationwide face-to-face interview survey of community-dwelling older adults was conducted, and the survey participants' health claims records were retrieved and linked under the universal health insurance system of Taiwan in 2018.MethodsHealth care outcomes were measured subjectively (patient satisfaction and perceived lack of coordination) and objectively (likelihood of hospital admissions and emergency department [ED] visits). COC was measured using claims-based and multidimensional patient-reported COC. Ordered logit and logit models were used to examine the relationship between the 2 types of COC measures, and health care outcomes were measured subjectively and objectively. Average marginal effects with bootstrapped SEs were computed for health care outcomes.ResultsThis study demonstrated that the correlations of claims-based and patient-reported COC measures were quite low and mainly insignificant. A higher claims-based COC was significantly associated with a lower likelihood of hospital admissions, ED visits, and perceived lack of coordination. No significant relationship was identified between claims-based COC and patient satisfaction. Participants reporting higher COC had better patient satisfaction and less perceived lack of coordination. However, no relationship was identified between patient-reported COC and the likelihood of hospital admissions and ED visits.ConclusionsThe correlation between claims-based and patient-reported COC measures is low, and claims-based and patient-reported COC measures are associated with different subjective and objective health care outcomes. We suggest that claims-based COC indicators representing the pattern of physician visits might be considered a unique dimension of COC.
