Automated AI Voice Calls for Postoperative Orthopedic Follow-up: A Randomized Trial of SMS Pre-notification and Blinded Validation of PROM Capture.

Institut de Chirurgie Reparatrice Locomoteur et Sports·interventional·Posted Jul 22, 2021·Updated Feb 20, 2026

In Brief

A clinical study evaluating SMS Pre-notification and No Pre-notification for Shoulder Instability. Completed, enrolled 310 participants across 1 site.

Detailed Summary

This prospective, single-center randomized clinical trial evaluates the technical efficacy, accuracy, and operational performance of an automated conversational artificial intelligence (AI) voice agent for postoperative follow-up after arthroscopic shoulder instability surgery. The study examines whether SMS pre-notification improves survey completion during the first automated outbound call and assesses the accuracy of AI-captured patient-reported outcomes compared with blinded human review.
