简要总结

This study evaluates the effectiveness of price discounts in encouraging patients to schedule dental check-ups. Patients will be randomized to receive WhatsApp messages offering a preventive dental check-up at different price levels with or without a discount coupon for future dental treatments.

详细描述

Patients in this trial will be randomized to either one Holdout condition, where patients do not receive any WhatsApp message or communications about dental check-ups, or to one of three treatment conditions where patients receive one WhatsApp message encouraging them to get preventive dental check-ups, offered by their hospital. The three treatment conditions differ in the price of the check-up stated in the message and the inclusion of a discount coupon.

  1. Large price discount condition: Patients receive an offer to get a preventive dental check-up for $4,990 CLP.
  2. Intermediate price discount condition: Patients receive an offer to get a preventive dental check-up for $9,990 CLP.
  3. Intermediate price discount plus coupon condition: Patients receive an offer to get a preventive dental check-up for $9,990 CLP plus a discount coupon for future treatments. The coupon value is CLP 20,000 for treatments costing over CLP 150,000 and is subject to additional terms and conditions by the hospital.

The original price of the preventive dental check-up is $24,990 CLP.

Randomization to study conditions will be stratified by whether patients are from Group 1 or 2 (see participation criteria).

The investigators ask the following research questions:
