Informed consent is mandatory prior to any surgical procedure in medical practice. Consent requires voluntary agreement, the capacity to consent, and proper prior information. Literature shows that traditional methods of informing patients and guardians may not provide enough understanding of all risk, benefits and expectations associated with scoliosis surgery in pediatric patients. Scoliosis is the most common spinal disorder in pediatric patients. Treatment depends on curvature size and skeletal maturity, and surgery is reserved for curvatures greater than 45 degrees. This study aims to assess the impact of introducing a co-developed multimedia tool to improve guardians’ understanding of the surgical discussion and informed consent prior to PSIF. The primary objective is to measure the effect of this intervention using the results from test and post-test. Secondary objective includes observing if this tool improves guardians’ perceived understanding. It is hypothesized that the multimedia tool will improve comprehension and perceived understanding when compared to traditional methods. Specific aims involved describing, quantifying, and comparing questionnaire results in three distinct educational times during the pre-operative process, as well as results from the patient engagement evaluation tool. A quasi-experimental, repeated measures, multi methods approach was applied to analyze the results of a multiple-choice questionnaire between two groups (Pathway A and Pathway B), about the pre-operative surgical discussion process and content. Quantitative and qualitative data were obtained from the public and patient engagement evaluation tool to assess the patient engagement strategy implemented for the co-development of the educational video tool. Seventeen participants were included in this study, eight assigned to Pathway A and nine to Pathway B. No significant difference was seen between results from Pathway A and Pathway B. However, the effect of knowledge acquisition over time was significant, indicating a substantial temporal progression on the outcome. The results demonstrate promising outcomes regarding knowledge acquisition over time when introducing a secondary information delivery method to the current consent process. Patient engagement evaluation tool findings display positive results reinforcing the efforts to ensure the CIHR guiding principles during the creation of the educational video.
