ABSTRACT

BACKGROUND

Patient decision aids facilitate informed decision making for medical tests and procedures that have uncertain benefits.

OBJECTIVE

To describe participants’ evaluation and utilization of print-based and web-based prostate cancer screening decision aids that were found to improve decisional outcomes in a prior randomized controlled trial.

DESIGN

Men completed brief telephone interviews at baseline, one month, and 13 months post-randomization.

PARTICIPANTS

Participants were primary care patients, 45-70 years old, who received the print-based (N = 628) or web-based decision aid (N = 625) and completed the follow-up assessments.

MAIN MEASURES

We assessed men’s baseline preference for web-based or print-based materials, time spent using the decision aids, comprehension of the overall message, and ratings of the content.

KEY RESULTS

Decision aid use was self-reported by 64.3 % (web) and 81.8 % (print) of participants. Significant predictors of decision aid use were race (white vs. non-white, OR = 2.43, 95 % CI: 1.77, 3.35), higher education (OR = 1.68, 95 % CI: 1.06, 2.70) and trial arm (print vs. web, OR = 2.78, 95 % CI: 2.03, 3.83). Multivariable analyses indicated that web-arm participants were more likely to use the website when they preferred web-based materials (OR: 1.91, CI: 1.17, 3.12), whereas use of the print materials was not significantly impacted by a preference for print-based materials (OR: 0.69, CI: 0.38, 1.25). Comprehension of the decision aid message (i.e., screening is an individual decision) did not significantly differ between arms in adjusted analyses (print: 61.9 % and web: 68.2 %, p = 0.42).

CONCLUSIONS

Decision aid use was independently influenced by race, education, and the decision aid medium, findings consistent with the ‘digital divide.’ These results suggest that when it is not possible to provide this age cohort with their preferred decision aid medium, print materials will be more highly used than web-based materials. Although there are many advantages to web-based decision aids, providing an option for print-based decision aids should be considered.
