Digital Health Platform Blood Pressure Management Study

Reduction in Systolic and Diastolic Blood Pressure at 6 Months by Home Blood Pressure Monitoring

Change in average systolic and diastolic blood pressure (SBP and DBP) from baseline to 6 months, measured using validated automated home blood pressure monitors. Participants will follow the 722 protocol (2 readings per occasion, twice daily, over 7 consecutive days). Data are collected via the digital health platform and automatically uploaded. Outcome is calculated as the difference in mean SBP between baseline and 6-month readings. \[Unit of Measure: mmHg\]; \[Method of Assessment: Home blood pressure monitoring (HBPM) using certified devices (certified by Taiwan FDA)\]

Reduction in Systolic and Diastolic Blood Pressure at 12 Months by Home Blood Pressure Monitoring

Change in average systolic and diastolic blood pressure (SBP and DBP) from baseline to 12 months, measured using validated automated home blood pressure monitors. Participants will follow the 722 protocol (2 readings per occasion, twice daily, over 7 consecutive days). Data are collected via the digital health platform and automatically uploaded. Outcome is calculated as the difference in mean SBP between baseline and 6-month readings. \[Unit of Measure: mmHg\]; \[Method of Assessment: Home blood pressure monitoring (HBPM) using certified devices (certified by Taiwan FDA)\]

Improvement in Hypertension Knowledge, Attitudes, and Behaviors (KAB)

Change in participants' scores on a validated Hypertension Knowledge, Attitudes, and Behaviors (KAB) questionnaire between baseline and 6-month follow-up. The questionnaire assesses understanding of blood pressure management, behavioral intentions, and lifestyle practices. Statistical evaluation using Wilcoxon Signed-Rank Test. \[Unit of Measure: Score on KAB questionnaire\]; \[Method of Assessment: Structured questionnaire administered digitally before and after intervention\]

Adherence to 722 Blood Pressure Monitoring Protocol and Medication Compliance

Proportion of participants who complete home blood pressure monitoring in accordance with the 722 protocol and demonstrate adherence to their prescribed antihypertensive medication regimen. * BP Monitoring Adherence: At least 2 measurements per occasion, twice daily (morning and evening), for 7 consecutive days. * Medication Compliance: Taking prescribed antihypertensive medication(s) as directed (correct dosage and frequency) over the same monitoring periods. Adherence is defined as meeting both criteria at baseline and again at 6 months. This measure reflects participants' engagement with blood pressure self-monitoring behaviors and their consistency in following prescribed treatment. \[Unit of Measure: Percentage of participants\]; \[Method of Assessment: * App-based log review of BP measurements synced from devices. * Medication adherence assessed via app-based self-reports.\]

Change in Time in Therapeutic Range (TTR) for Systolic Blood Pressure

Change in the proportion of days during which a participant's home systolic blood pressure readings are within the target range (110-130 mmHg) over a 7-day observation period at baseline and at 6 months. TTR is calculated as the number of days with SBP within target range divided by total valid measurement days (minimum of 4 valid days required per observation period). Improvement in TTR reflects better blood pressure stability. \[Unit of Measure: Percentage of days in target range\]; \[Method of Assessment: Home blood pressure monitor data uploaded via app and analyzed based on Taiwan Hypertension Society's TTR definition\]
