Appropriate hospital-to-home transitional care has been recognized for its positive impact on health care usage and health outcomes in patients with COPD. However, there is limited research assessing its effects on patient-centered outcomes, focusing on patient symptoms and experiences. This single-blind randomized controlled trial included subjects diagnosed with COPD at one of 2 university hospitals in South Korea. The study included 179 subjects (transitional care group [transitional care], 87; usual care group [usual care], 92). The transitional care received transitional care comprising post-discharge care planning, personalized education, breathing exercises, telephone counseling, home visits, and referral to social services. We analyzed the effects of these interventions by comparing breathing symptoms and various patient-centered outcomes between the 2 groups. The Modified Medical Research Council scores (mean [SD], transitional care 1.3 [1.06], usual care 1.82 [1.1], P = .002) and COPD Assessment Test scores (transitional care 6.32 [5.5], usual care 9.43 [7.16], P = .001) in the intervention group demonstrated more significant improvement than did those in the usual care. Following intervention, the subjects exhibited enhanced awareness of their disease, an increased frequency of inhaler use (transitional care 49.69 [1.67], usual care 46.86 [7.92], P = .002), and lower depression and anxiety scores. Additionally, the transitional care outperformed the usual care in the domain of subject experience during hospitalization (transitional care 39.34 [6.14], usual care 37.5 [5.61], P = .036), preparedness before discharge (transitional care 34.54 [4.96], usual care 32.3 [5.09], P = .003), and post-discharge management (transitional care 34.72 [4.36], usual care 30.29 [4.26], P = .003). Evidence-based transitional care services can exert positive effects on patient-centered indices. Our findings can be used as evidence of the need to establish patient-centered transitional care as a form of universal care for patients with COPD.
