Trial Outcomes & Findings for The Personal Patient Profile Decision Support for Patients With Bladder Cancer (NCT NCT05033067)

After obtaining IRB approval for the feasibility study, we approached 114 patients for recruitment into The Personal Patient Profile Decision Support for Patients with Bladder Cancer (P3-BC) study. Of these, 24 patients consented to participate. Common reasons for declining included disease and treatment burden, limited time, and lack of confidence in using technology independently.

Among those who consented, 4 participants were lost to follow-up prior to participation, leaving 20 participants (83%) who engaged with the web-based tool's survey. Of these, 5 participants did not complete sufficient baseline survey engagement (i.e., completing the tool's survey that precedes the randomization step) with the tool and were therefore not assigned to a study group. The remaining 15 participants were randomized, with 10 assigned to the intervention group and 5 to the usual care.

The Personal Patient Profile Decision Support for Patients With Bladder Cancer

Percentage of participants who agreed with the statements taken from the Survey-based Acceptability Measure Acceptability is assessed with the 13-item web-based scale in addition to items designed by the research team for the 1-month follow-up to evaluate acceptability. The acceptability is defined as 80% acceptable ratings. Using well-established feasibility criteria to assess: 1) retention/drop-out rates, and 2) duration and completion rate of study assessments. The scale uses a 5-point response scale for each item (1=not acceptable, 5=highly acceptable). Responses were categorized to agree (scores 1-2 strongly agree/agree), or disagree (scores 3-5; strongly disagree, disagree, I don't know.

A 1-month follow-up questionnaire included 11 additional items assessing participants' perceptions of study procedures, acceptance of the intervention, and satisfaction with the decision aid. Responses were categorized to agree (scores 1-2 strongly agree/agree), or disagree (scores 3-5; strongly disagree, disagree, I don't know).

Investigator-designed 12-items instrument to evaluate intervention participants' opinions and acceptance of study procedures and their satisfaction with the decisional aid. Responses for each item range from strongly agree (1) to strongly disagree (4), with higher scores indicating greater dissatisfaction with the intervention. Original responses (1-5 visual analogue scale) were categorized as Low (scores 1-2), Neutral (score 3), or High (scores 4-5). with higher scores indicating greater dissatisfaction with the intervention.

Shared decision making (SDM) was assessed by the SDMQ-9. The 9 items are rated on a 6-point Likert scale ranging from 0 (completely disagree) to 5 (completely agree). Final scores are sum of rating, which ranges between 0 and 45, higher score indicates more positive attitude towards SDM.

Consists of 16 item scale measuring effectiveness on decision making. Items are given a score value of 0 = strongly agree, 1 = agree, 2 = neither agree nor disagree, 3= disagree, and 4 = disagree, full scale from 0 - 64 with higher total scores indicating higher decisional conflict.

Brief Symptom Index (BSI-18) was used psychological to assess distress. BSI-18 is a self-report 18-item instrument. Index full scale is scored .00 to 0.94 with higher scores indicating more distress.

The Decisional Regret Scale consists of 5 item scale assessing regret of treatment decisions made. Each item scored from 1 to 5. Full scale is scored 1-25. Higher score indicates higher regret of treatment decisions.

The Cancer Rehabilitation Evaluation System (CARES-MIS) - Medical Interaction Subscale was used to assess perceived problems with communication with providers. The CARES - Medical Interaction Subscale includes 11 items rated on 5-point scale, where 0 represents "not at all" and 4 represents that problem occurred "very much". Total scores range from 0-44 for The CARES-MIS. 5 items were selected from The CARES-MIS, total subscale score range is 0-20, with higher scores indicating poorer perceived communication

A 14 investigator-designed items evaluating patients' knowledge about bladder cancer. Scores range from 1 (Completely certain that is true) to 5 (Completely certain that is false). After recording the items to 1 (true) and 0 (false) total sum score of this scale range from 0 -14, with higher scores indicating more knowledge about bladder cancer.
