Current status of remote collaborative care for hypertension in medically underserved areas

Abstract

Background: Remote collaborative care (ReCC) is a legally recognized form of telehealth that facilitates communication between physicians. This study aimed to analyze the effectiveness of ReCC services and establish a foundation for the usefulness and effectiveness of ReCC. Methods: This retrospective cohort study utilized data from the Digital Healthcare Information System (DHIS) managed by the Korea Social Security Information Service. We extracted data on patients who were registered from January 2017 through September 2023 to investigate the effects of various factors. Results: A total of 10,407 individuals participated in the remote collaborative consultation service provided by the DHIS. Of these participants, those aged ≥80 years represented 39.2% (4,085 patients), while those aged 70 to 79 years comprised 36.9% (3,838 patients). The conditions treated included hypertension, affecting 69.2% (7,203 patients), and diabetes, affecting 21.1% (2,201 patients). Although various measurement items were recorded, most data beyond blood pressure readings were missing, posing a challenge for analysis. Notably, there was a significant reduction in blood pressure that was sustained at follow-up intervals of 1, 3, 6, and 12 months post-baseline (all P<0.05). Conclusions: Owing to the lack of data, follow-up assessments for conditions other than hypertension proved to be challenging. Medical staff should increase their focus on and engagement with the system. Remote consultations have demonstrated efficacy in managing hypertension in medically underserved areas, where access to healthcare services is often limited. This suggests the potential for expanded use of remote chronic care in the future.
