Structured Preoperative Phone Counseling by Junior Medical Staff for Improving the Consent Process for Tonsillectomy

To assess the effectiveness of preoperative phone counseling by junior medical staff for improving the standard of informed consent for tonsillectomy.

Prospective randomized controlled trial.

District general hospital.

A total of 43 patients undergoing tonsillectomy were randomly allocated to 2 groups. Group A (n = 25) underwent the conventional consent process by the consultant ear, nose, and throat surgeon at the time of assessment (which generally takes place 6 to 12 months prior to surgery due to wait-list times). Group B (n = 18) underwent this same consent process but received a structured preoperative phone call 2 to 3 weeks prior to the day of surgery. A preoperative questionnaire assessing the knowledge of tonsillectomy, perioperative course, and risks was completed on the day of surgery.

Group B had a better recall of the risks of tonsillectomy, recalling 7.1 of the 10 most significant risks, as compared with 4.6 for group A (P = .017). Group B had a better awareness of tooth damage (78% vs 30% of patients, P ≤ .001), voice change (61 vs 19%, P = .005), and burns to lips and mouth (44% vs 8%, P = .005). Finally, 35% more patients from group B rated their understanding of tonsillectomy as good or very good (P = .017).

Preoperative phone counseling by junior medical staff closer to the time of surgery reinforces and clarifies the information previously provided by senior consultants at the time of initial consent for tonsillectomy.
