About this study

Official title: Effect of a Behavioral Intervention Delivered Via Telegram Messenger on Smoking Cessation in Patients After Myocardial Infarction: The TELEGRAM-MI Randomized Controlled Trial

This randomized controlled trial will evaluate whether a 6-month behavioral intervention delivered via Telegram messenger increases smoking cessation rates in patients after myocardial infarction (MI).

Adult smokers hospitalized with acute MI who regularly use Telegram will be randomly assigned to either:

Read more
  • INTERVENTION GROUP: Standard care plus a 6-month Telegram chatbot program providing personalized motivational messages, cognitive-behavioral techniques for craving management, and relapse prevention support.
  • CONTROL GROUP: Standard care (routine physician advice to quit smoking) plus basic surveys via Telegram without therapeutic content.

The primary outcome is 30-day point prevalence abstinence at 6 months, verified by blinded telephone interview with participant and corroborating report from a close relative. Secondary outcomes include changes in cigarette consumption, nicotine dependence, motivation, and intervention engagement metrics.

This study addresses the critical gap in smoking cessation support after hospital discharge and could provide evidence for a scalable digital health solution in cardiac secondary prevention.

Read the detailed description

The TELEGRAM-MI trial is a multicenter, randomized, controlled, assessor-blinded superiority study testing a digital behavioral intervention for smoking cessation in post-myocardial infarction patients.

BACKGROUND: Smoking cessation is the most effective modifiable risk factor for reducing mortality after MI, yet long-term abstinence remains challenging due to limited sustained support. Digital interventions using popular messaging platforms offer a scalable solution to bridge the post-discharge support gap.

OBJECTIVES:

Primary: To determine if a 6-month Telegram chatbot intervention increases 30-day point prevalence abstinence rates at 6 months compared to standard care alone.

Secondary: To examine associations between baseline characteristics (nicotine dependence, motivation), engagement metrics, and cessation success; and to assess intervention acceptability.

METHODS: Approximately 142 participants will be recruited from inpatient cardiology departments. After providing informed consent, participants will be randomized 1:1 via the chatbot to either the intervention group (standard care plus 6-month behavioral support) or control group (standard care plus data collection only). The intervention incorporates evidence-based techniques including motivational messaging, cognitive-behavioral strategies, and relapse prevention protocols.

OUTCOMES: The primary outcome is biochemically unverified 30-day point prevalence abstinence at 6 months, assessed via blinded telephone interview with participant and relative verification. Secondary outcomes include various smoking behavior metrics collected through the chatbot platform.

ANALYSIS: Primary analysis will follow intention-to-treat principles, with missing data imputed as smoking. Statistical analyses will include chi-square tests for primary outcome and regression models for secondary outcomes.

POTENTIAL IMPACT: If effective, this intervention represents a readily implementable, low-cost strategy to enhance secondary prevention in cardiac patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Telegram-based Smoking Cessation SupportBehavioural

    A 6-month behavioral intervention delivered via a Telegram chatbot. The intervention includes personalized daily motivational messages, cognitive-behavioral techniques for craving management, access to an SOS/craving support button, weekly check-ins, and relapse prevention protocols. Content is tailored based on user responses to questionnaires (Fagerström Test, Importance/Confidence scales) and engagement metrics.

  • Standard Care (in control arm)Other

    Routine physician advice to quit smoking provided upon hospital discharge. This represents the current standard of care in the participating clinical centers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 30-day point prevalence abstinence (PPA)

    Proportion of participants who report abstinence from smoking for the past 30 days or more, verified by both participant self-report AND corroborating report from a close relative or cohabiting person during a telephone interview conducted by a blinded assessor. A positive outcome is recorded ONLY if both sources confirm abstinence. Participants with missing data (e.g., lost to follow-up) will be considered smokers in the primary analysis (intention-to-treat).

    Measured: 6 months

Secondary outcomes (7)
  1. 7-day point prevalence abstinence (7-day PPA)

    Proportion of participants who report abstinence from smoking for the past 7 days. Assessed via the Telegram bot.

    Measured: 1 month and 3 months

  2. Change in cigarette consumption

    Change from baseline in the self-reported number of cigarettes smoked per day. Assessed via the Telegram bot.

    Measured: Baseline, 1 month, 3 months, and 6 months

  3. Score on the Fagerström Test for Nicotine Dependence (FTND)

    Change in nicotine dependence measured by the FTND questionnaire (score range 0-10, higher scores indicate greater dependence). Assessed via the Telegram bot.

    Measured: Baseline and 6 months

  4. Motivation to quit (Importance and Confidence Scales)

    Scores on self-rated scales (0-10) for the importance of quitting and confidence in the ability to quit. Assessed via the Telegram bot.

    Measured: Baseline and 6 months

  5. Participant engagement with the Telegram bot

    Composite measure of engagement (dose) including: proportion of completed weekly check-ins, proportion of opened messages, number of SOS/craving button uses, number of active weeks. Metrics are automatically logged by the bot.

    Measured: 6 months

  6. Intervention acceptability and satisfaction

    Total score on a custom acceptability and satisfaction questionnaire (5-12 items) completed by participants in the intervention group via the Telegram bot. Higher scores indicate higher satisfaction.

    Measured: 6 months

  7. Time to first relapse

    Number of days from randomization to the first self-reported relapse (lapse) event. Assessed via continuous monitoring through the bot's check-in system.

    Measured: 6 months
