Background: Improving the comprehension and communication of patient education materials could augment patient participation in shared clinical decision making. Inadequate healthcare-oriented educational resources for patients with a newly diagnosed complex disease, such as a cerebral aneurysm, can lead to an insufficient understanding of their ailment. As such, we hypothesized that a PowerPoint-style educational intervention with grade-conscious (i.e., sixth grade level) written material accompanied by visual graphics would help improve patient health literacy and satisfaction.
Methods: A randomized prospective pilot study was conducted during a 1-year period in 2018. Preclinic encounter knowledge assessment surveys were administered to 52 patients with brain aneurysms (newly diagnosed or during follow-up) presenting for their neurosurgery outpatient clinic visit. The patients were assigned to 1 of 2 cohorts, with 26 each in the educational intervention group and control group, using a quasi-randomization method of alternating the assigned group for each successive patient. At the conclusion of their clinic encounter, all the patients completed a postclinic encounter knowledge assessment and satisfaction survey. Differences in covariates such as gender distribution, age, and family history of aneurysms were analyzed between the control and intervention groups.
Results: The overall study cohort had a high baseline knowledge about cerebral aneurysms with an average preclinic encounter score of 5.37 on the 7-question survey. The educational intervention resulted in an upward trend in the patient knowledge scores. No statistically significant difference was detected in the patient satisfaction scores between the intervention and control groups. However, most of the patients receiving the educational intervention reported that the educational material was easy to understand (95.7%), helpful (86.9%), and relevant (87%) to their clinic visit.
Conclusion: Overall, in the present prospective study, the use of a multimedia-based educational intervention resulted in an upward trend in knowledge without a statistically significant difference in patient satisfaction scores compared with the control patients. To better measure the effectiveness of multimedia-based patient education interventions, future studies should account for the patients' baseline education level, preexisting educational resources available to study patients, socioeconomic factors, and emotional state.
