Brief Summary

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

Conditions

Behavioral Intervention; Nicotine Addiction

Outcome Measures

Primary Outcomes (1)

• Patient attendance at scheduled follow-up visit

  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.

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

Secondary Outcomes (1)

• Impact of sociodemographic and clinical factors on patient attendance

  at baseline and 2 to 8 weeks after enrollment

Study Arms (3)

Standard of care - Text message

NO INTERVENTION

Participants will receive a standard, automated text message reminding them of their scheduled appointment. The message will be sent 1 day before the scheduled appointment. The content of the message will be limited to logistical information (date, time, and location) and instructions on how to reschedule or cancel the appointment.

Text message and standard phone call

EXPERIMENTAL

Participants will receive a text message (similar to Arm 1) one day before the appointment and, additionally, 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.

Behavioral: Standard phone call

Text message and phone call with MINDSPACE elements

EXPERIMENTAL

Participants will receive a short text message (similar to Arm 1) and 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 (Messenger, Incentives, Norms, Defaults, Salience, Priming, Affect, Commitments, Ego) 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.
