A Novel Strategy for Understanding What Patients Value Most in Informed Consent Before Surgery

TL;DR

This study identifies patient expectations and communication strategies that reduce anxiety during the informed consent process before surgery.

Contribution

A conjoint-based experimental design was used to uncover distinct patient mindsets and effective verbal communication messages in the informed consent process.

Findings

Three verbal communication messages significantly decreased pre-operative anxiety for all patients.

Three distinct patient mindsets were identified based on their expectations for surgeon communication.

Mindset 3 patients felt anxious due to insufficient time or unclear purpose of signing the consent form.

Abstract

Background/Objectives: To map and analyze patient expectations regarding communication in IC and identify communication that both heightens anxiety in the IC process and reduces anxiety in the IC process before surgery. Methods: Ethics approval was granted. A power analysis indicated a required sample of 90 patients. A conjoint-based experimental design was performed, post-discharge, overcoming typical biases of surveys. Results: The sample comprised 104 patients who underwent surgery in the last year. Three verbal communication messages were perceived as significantly decreasing pre-operative anxiety for the total sample. Mathematical clustering yielded three distinct mindsets. Post hoc ANOVA indices indicated that the mindsets were significantly different. Patients belonging to each mindset differed from patients belonging to other mindsets in their expectations from the dialogue with surgeons to mitigate their anxiety. Mindset 1 (70% of the sample) comprised patients who expected information that was tailored to their specific situation. To feel safer, they needed to know that nothing unexpected would happen. Mindset 2 (13%) comprised patients who expected providers to talk with them about benefits and risks at the clinic, not at the hospital, and have a dialogue with them. Mindset 3 (17%) comprised patients who perceived a lack of information regarding the purpose of signing the informed consent and lack of sufficient time to thoroughly read the form or signing the form minutes before the procedure as elements that would heighten their anxiety. Conclusions: Three verbal communication messages in the IC dialogue were thought to decrease pre-operative anxiety for all patients, as follows. “I want to make sure you read and understand the consent form entirely” “Everything is provided in clear and simple terms”. The surgeon says, “Let’s go over the entire form”.
