About this study
Official title: Reducing No-Shows in High-Risk Urology Patients Through Enhanced Preoperative Outreach
This study aims to evaluate the impact of reminder call intervention on no-shows for urologic procedures in patients identified to be high risk for no-showing. Patients scheduled to undergo a urologic procedure will be randomized into two groups: the intervention group, who receives a series of reminder calls and text messages about appointment details and patient questions prior to the procedure date; and the control group, who receives standard care only. Secondary outcomes include rates of patient re-scheduling and healthcare utilization.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Preoperative OutreachBehavioural
Participants will receive enhanced preoperative outreach consisting of reminder phone calls 7 days, 3 days, 1 day, and on the day of their scheduled urologic procedure, in addition to standard care. Calls will review appointment details, address patient questions, assess barriers to attendance, provide text-based communication access, and facilitate referral to social work when appropriate.
| Study group | Role | What they receive |
|---|---|---|
| Enhanced Preoperative Outreach | Experimental | Participants receive standard care plus reminder phone calls at 7 days, 3 days, 1 day, and the day of the procedure, text messaging access, assessment of barriers to attendance, and referral to social work when appropriate. Receives: Behavioral: Preoperative Outreach |
| Standard Care | No intervention | Participants receive standard preoperative care, including procedure scheduling, preoperative anesthesia evaluation, and routine surgery center reminder calls. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Procedure No-Show Rate
Whether the participant attended their scheduled urologic procedure
Measured: From enrollment until the scheduled procedure date (up to 8 weeks)
Secondary outcomes (1)
Procedure Rescheduling Rate
Whether the participant rescheduled their procedure
Measured: From enrollment until the scheduled procedure date (up to 8 weeks)
