Abstract: Numerous studies have investigated the relationship between continuity of care (COC) and patient satisfaction. However, COC and patient satisfaction were measured simultaneously; therefore, the direction of causality remains understudied. This study examined the effect of COC on the patient satisfaction of elderly individuals using an instrumental variable (IV) approach. Nationwide survey data acquired using a face-to-face interview were used to measure the patient-reported COC experiences of 1,715 participants. We applied an ordered logit model controlled for observed patient characteristics and a two-stage residual inclusion (2SRI) ordered logit model that accounted for unobserved confounding factors. Patient-perceived COC importance was used as an IV for patient-reported COC. The ordered logit models indicated that patients with high or intermediate patient-reported COC scores were more likely to perceive more patient satisfaction than those with low COC scores. Using the patient-perceived COC importance as an IV, we examined a strong significant association between the level of patient-reported COC and patient satisfaction. It is necessary to adjust for unobserved confounders to obtain more accurate estimates of the relationship between patient-reported COC and patient satisfaction. However, the results and policy implications of this study should be cautiously interpreted because the possibility of other bias could not be ruled out. These findings support policies aimed at improving patient-reported COC among older adults.
