NCT06581250

Brief Summary

The goal of this study is to compare different no-show interventions in dental clinics serving underserved populations. The main question it seeks to answer is

  • How do different no-show intervention methods compare in reducing no-shows? Participants will be asked to
  • Implement different interventions
  • Report a limited set of data to researchers

Outcome Measures

Primary Outcomes (1)

  • Change in proportion of scheduled appointments for which the patient attends, pre-to-post intervention

    To test the efficacy of motivation-enhanced communication, reminder messaging, and walk-in visits as compared to treatment as usual For each of the three interventions, the pre-to-post intervention change in show rates. Show rate is defined as the proportion of scheduled appointments for which the patient attends their scheduled clinic appointment. Appointments cancelled or rescheduled more than 24 hours in advance are not included in the calculation. Outcome will be measured by data exported from the clinical electronic health records monthly.

    6 months pre-intervention to 12 months post-intervention

Secondary Outcomes (3)

  • Organizational Change Manager (OCM) Score

    Survey will be administered at 3 months

  • Statistical Comparison of Interventions for Effectiveness Analysis

    6 months pre-intervention to 12 months post-intervention

  • Statistical Comparison of Combining Multiple Interventions for Interaction Analysis

Interventions

Dental clinic staff will use scripts to contact patients 24 and 48 hours before appointments. These scripts will guide staff in confirming the patient will appear for their appointment.

Walk-in VisitsBEHAVIORAL

When contacting patients to schedule an appointment (by phone, email, text, or other methods), dental clinic staff will notify patients of times during which patients can walk-in for a dental visit, if convenient for them; otherwise, a regular appointment will be arranged. Scheduled appointments will continue to be available in addition to the walk-in hours.

Participating clinic site staff will be trained in motivation-enhanced communication techniques using the guide for dental clinic sites and coaching. Topics to be included in the motivation-enhanced communication training are a) to determine what patients hope to gain from their dental care, steps needed to succeed, how the agency and client will work together to attain the goals, and b) to identify patient barriers to attending their visit (e.g., transportation, payment, do not understand need for visit, etc.), and what the agency and patient will do to overcome those barriers. Staff will be instructed to use these techniques with patients at every contact about an upcoming appointment.

Intervention Model
FACTORIAL
Model Details: The study uses a 2x2x2 factorial cluster-randomized design The unit of intervention and randomization will be dental clinic sites (clusters). Forty clinics will be randomized between eight possible combinations of receiving or not receiving the three study interventions. The factorial structure of the design ensures that 20 clinic sites receive each intervention, and 20 do not. Five clinic sites will receive none of the interventions, five clinics will receive all three interventions, and 30 clinic sites will receive a different combination of 2 of the 3 interventions.
