Abstract

Objectives To establish the proportion of men who chose to include Overdiagnosis as a criterion in an online multi-criteria decision aid for the prostate cancer screening decision; and to determine the relative importance assigned to Overdiagnosis by those who included it in their personalised aid. Methods The data are from the 'Pick Your Own' arm of an Australian community panel-based trial involving men aged 40-69 years without diagnosed prostate cancer. The 720 participants were asked to choose between 1 and 10 criteria for inclusion in their aid. With only Overdiagnosis spelled out here, the criteria, all preceded by ‘Avoiding’, were: LOSS OF LIFETIME; LOSS OF HEALTH; NEEDLESS BIOPSY; OVERDIAGNOSIS (and needless treatment) as a result of a PSA test detecting a cancer that would not have affected your life or health; URINARY PROBLEMS; BOWEL PROBLEMS; SEXUAL PROBLEMS; BURDEN of TREATMENT; BURDEN to CARERS; REGRET. Participants were asked to indicate the relative importance for their selected criteria by changing bar lengths on screen with their cursor. Their weights automatically adjusted to add to 100%.
Results 77% (377) of study participants included Overdiagnosis, 57 % (131) of those who excluded at least one of the 10. If 5 criteria were selected, 47% included Overdiagnosis, as did 41% who selected 4 or 6. Average weights assigned to Overdiagnosis amongst those providing a complete set of weights increased from 9% to 19% as the included number decreased. Highest weight for Overdiagnosis was 33%.
Conclusions Overdiagnosis was prominent among the criteria selected from a menu by male members of the public participating in a trial of online multi-criteria decision aids for prostate cancer. Notably, over 40% of those who excluded 4 to 6 of the 10 criteria included Overdiagnosis in their aid. Moderate weights were attached to it, varying with the number of criteria selected.
