Main Article Content
Abstract
Background and Objectives:
Mobile Telemedicine to enhance hypertension management is increasingly used in primary care in Thailand; however, Studies evaluating the efficacy of blood pressure control give contradictory findings, and efficacy in rural areas is unclear. This study aimed to assess the efficacy of mobile telemedicine for blood pressure control in hypertension patients in primary care, compared with usual care.
Design: A retrospective cohort study
Materials and Methods:
A retrospective cohort study examined the data of patients with hypertension in a telemedicine clinic and a usual care clinic between December 2019 to February 2021. One hundred twenty hypertensive patients data was sampled from both primary care clinics; eligible patients were adults (30 to 65 years old). Patients with a history of ischemic heart disease, cerebrovascular disease, chronic kidney disease stage 4 or worse, and evidence of secondary hypertension were excluded. Blood pressure, the proportion of controlled hypertensive patients, and blood pressure change were measured 6 months after the intervention.
Results:
Of the 240 patients recruited, 212 completed data collection after 6 months. Age, sex, body weight, blood pressure, and the proportion of controlled blood pressure patients were similar in both groups. After 6 months of follow-up, there were no significant differences in systolic blood pressure (134.3 mmHg vs. 132.9 mmHg, p=0.462), Systolic blood pressure change from baseline (1.7 mmHg vs. -0.1 mmHg, p=0.402), and proportion of control blood pressure patients (38.5 % vs. 49.1 %, p=0.120)
Conclusions:
The clinical outcome and blood control showed no significant difference in telemedicine and usual care groups, So mobile-based telemedicine is the one of alternative choice for management in hypertension patients; however, the long-term clinical outcome should be evaluated in the future.
