Learning Implementation of Guideline-based Decision Support System for Hypertension Treatment: Testing Alternative Antihypertensive Regimens Using ACE-Inhibitors, Calcium Channel Blockers and Diuretics (LIGHT-ACD)

Not Applicable

• Conditions: Hypertension

• Registration Number: NCT03587103
• Lead Sponsor: China National Center for Cardiovascular Diseases

Brief Summary

This trial aims to compare the efficacy of several guideline-based hypertensive medication regimens initiated with Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Blocker \[A\], Calcium Channel Blocker \[C\] and Diuretic \[D\].

Detailed Description

The LIGHT-ACD Trial is conducted based on the LIGHT trial and aims to compare the efficacy of several guideline-based hypertensive medication regimens initiated with A, C and D for BP control.

Primary Outcome Measures

Name	Time	Method
Average change in BP from first visit after the decision support system is installed to 9-month among the individuals who initiated with A, C, and D (population 1) and among those who initiated with two-drug therapy with AC, AD or CD (population 2)	Baseline; 1 year	Average change in BP from first visit after the decision support system is installed to 9-month among population 1 (SBP 140-159 mmHg, not currently taking any antihypertensive medications) who initiated with A, C, and D and among population 2 (SBP≥160 mmHg, taking 0-1 antihypertensive medications which is not B; or SBP 140-159mmHg, taking one antihypertensive medication which is not B) who initiated with two-drug therapy with AC, AD or CD, respectively.

Secondary Outcome Measures

Name	Time	Method

Baseline; 1 year	Proportion of individuals intolerant to each of the four medications among the individuals (population 1: SBP 140-159 mmHg, not currently taking any antihypertensive medications) who initiated with A, C, and D, among those (population 2: SBP≥160 mmHg, taking 0-1 antihypertensive medications which is not B; or SBP 140-159mmHg, taking one antihypertensive medication which is not B) who initiated with two-drug therapy with AC, AD or CD.
Proportion of individuals with BP<160/100 mmHg at 9 month.	Baseline; 1 year	Proportion of individuals with BP\<160/100 mmHg at 9 month among the individuals (population 1: SBP 140-159 mmHg, not currently taking any antihypertensive medications) who initiated with A, C, and D, among those (population 2: SBP≥160 mmHg, taking 0-1 antihypertensive medications which is not B; or SBP 140-159mmHg, taking one antihypertensive medication which is not B) who initiated with two-drug therapy with AC, AD or CD separately.
Proportion of individuals with BP<140/90 mmHg at 9 month.	Baseline; 1 year	Proportion of individuals with BP\<140/90 mmHg at 9 month among the individuals (population 1: SBP 140-159 mmHg, not currently taking any antihypertensive medications) who initiated with A, C, and D, among those (population 2: SBP≥160 mmHg, taking 0-1 antihypertensive medications which is not B; or SBP 140-159mmHg, taking one antihypertensive medication which is not B) who initiated with two-drug therapy with AC, AD or CD.
Proportion of individuals who received monotherapy, two-drug treatment, three-drug treatment, or referral at 9 month.	Baseline; 1 year	Proportion of individuals who received monotherapy (only in populations 1), two-drug treatment, three-drug treatment, or referral at 9 month among the individuals (population 1: SBP 140-159 mmHg, not currently taking any antihypertensive medications) who initiated with A, C, and D, among those (population 2: SBP≥160 mmHg, taking 0-1 antihypertensive medications which is not B; or SBP 140-159mmHg, taking one antihypertensive medication which is not B) who initiated with two-drug therapy with AC, AD or CD.
Proportion of individuals who switched to usual care for any reason.	Baseline; 1 year	Proportion of individuals who switched to usual care for any reason among the individuals (population 1: SBP 140-159 mmHg, not currently taking any antihypertensive medications) who initiated with A, C, and D, among those (population 2: SBP≥160 mmHg, taking 0-1 antihypertensive medications which is not B; or SBP 140-159mmHg, taking one antihypertensive medication which is not B) who initiated with two-drug therapy with AC, AD or CD.
