NCT02888769

Brief Summary

The study is a two-arm, parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention, including lifestyles modification, medication adherence improvement and risk factors control among coronary heart disease (CHD) patients without diabetes. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive 6 pre-designed text messages per week in addition to usual care for 6 months, while the control group will receive usual care.

Outcome Measures

Primary Outcomes (1)

  • Change in systolic blood pressure obtained in office during each interview

    The investigators will measure the change in systolic blood pressure from baseline to 6 months.

    Baseline; 6months

Secondary Outcomes (6)

  • Change in proportion of patients achieving a SBP<140mm Hg

    Baseline; 6months

  • Change in low-density lipoprotein cholesterol (LDL-C) level

    Baseline; 6months

  • Change in body mass index (BMI)

    Baseline; 6months

  • Change in medication adherence

    Baseline; 6months

  • Change in level of physical activity measured via International Physical Activity Questionnaire (IPAQ) scale

    Baseline; 6months

  • +1 more secondary outcomes

Study Arms (2)

Intervention-Text messaging

EXPERIMENTAL

Patients will receive regular semi-personalized text messages for 6 months. Each participants will receive 6 text messages per week, which will be sent at random times of the day (9.00am, 12noon, 4.00pm). Non-smokers will receive two general messages, two hypertension messages, one medication adherence message and one physical activity message per week. Smokers will receive one general message, two hypertension messages, one medication adherence message, one physical activity message and one smoking cessation message per week.

Behavioral: Text Messaging

Control

NO INTERVENTION

Participants in the control group will receive 2 thank-you messages per month and undertake routine clinical practice.

Text MessagingBEHAVIORAL

Patients will receive regular semi-personalized text messages for 6 months. Each participants will receive 6 text messages per week, which will be sent at random times of the day (9.00am, 12noon, 4.00pm). Non-smokers will receive two general messages, two hypertension messages, one medication adherence message and one physical activity message per week. Smokers will receive one general message, two hypertension messages, one medication adherence message, one physical activity message and one smoking cessation message per week. Prior to study commencement, a bank of 280 messages have been developed based on guidelines and behavior change theory (BCT), and have underwent multidisciplinary expert review and qualitative review process.
