Impact of Appointment Reminder Strategies on Smoking Cessation Clinic Attendance

The goal of this clinical trial is to learn whether different appointment reminder methods can improve attendance at an anti-smoking (smoking cessation) clinic among adult smokers.

The main question it aims to answer is:

"Which reminder method helps participants come to their scheduled smoking cessation clinic appointments most often?" Researchers will compare different appointment reminder methods with standard appointment scheduling to see if they help participants attend their clinic visits more often.

Participants will:

* Receive appointment reminders using different methods * Come to their scheduled visits at a smoking cessation (anti-nicotine) clinic

Treatment and study plan

Standard phone call

Behavioral

Participants will receive a phone call from a trained staff member 1-5 days before the appointment. The conversation will follow a strictly standardized script limited solely to confirming the appointment date, without any motivational or therapeutic elements.

phone call with MINDSPACE elements

Behavioral

Participants will receive a phone call 1-5 days before their appointment. The conversation will follow a standardized script incorporating behavioral intervention (nudging) elements based on the MINDSPACE framework. Key components of the script include:

  • Messenger (Sender): Emphasizing that the information comes from the medical team.
  • Norms (Social Norms): Referring to success statistics for regular visits.
  • Commitment: Encouraging verbal confirmation of attendance.
  • Affect (Emotions): Providing short messages reinforcing a sense of support.

Other names: MINDSPACE

Primary outcomes

  1. Patient attendance at scheduled follow-up visit

    Time frame: At the second scheduled visit at the Nicotine Cessation Clinic (2-8 weeks after baseline).

    Primary Outcome: The primary outcome measure is a binary assessment of patient attendance (Present/Absent) at the scheduled second visit, which takes place 2-8 weeks after the initial visit, as determined by the physician's individual assessment. Attendance will be verified on the day of the scheduled visit based on objective data recorded in the "CliniNET" hospital system.

Secondary outcomes

  1. Impact of sociodemographic and clinical factors on patient attendance

    Time frame: at baseline and 2 to 8 weeks after enrollment

    Secondary Outcomes: Secondary analyses will include an assessment of the impact of sociodemographic and clinical factors based on tests routinely performed as part of a medical visit (age, sex, level of dependence according to the Fagerström Test for Nicotine Dependence (FTND)).
