- Patient decision aids on prostate cancer screening are associated with a small reduction in decisional conflict and a small increase in patient knowledge.
- Decision aids are not associated with screening discussion and actual screening decisions.
Why this matters
- No formal testing of decision aids is done.
- Meta-analysis of 19 eligible trials including 12,781 individuals in whom clinicians used decision aids or usual care for prostate cancer screening for deciding routine prostate cancer screening.
- Outcomes: patient knowledge regarding prostate cancer screening, decisional conflict, screening discussion, actual screening decision, and decision satisfaction.
- Funding: Academy of Finland.
- Decision aids vs usual care were associated with:
- small improvement in knowledge (risk ratio, 1.38; 95% CI, 1.09-1.73) and
- small decrease in decisional conflict (mean difference on a 100-point scale, −4.19; 95% CI, −7.06 to −1.33).
- Decision aids were not associated with:
- screening discussions between individual and their physicians (risk ratio, 1.12; 95% CI, 0.90-1.39) and
- actual screening decision (risk ratio, 0.95; 95% CI, 0.88-1.03).
- 3 studies reported satisfaction with the decision: 2 reported no association and 1 reported greater satisfaction in participants with printed material at 1 month, but no difference in satisfaction at 13 months.
- Low- to moderate-quality evidence.
