Overview
Brief Summary
This clinical trial evaluates the use of novel decision support educational materials and services using health coaches. The study includes men newly diagnosed with low-risk prostate cancer. A 160 men will be recruited. Half of the men will receive a call from a health coach before their initial consultation visit with their urologist to review their treatment concerns and questions. The other half will receive usual care provided by the urologist, such as educational materials and services provided by the urologist.
Detailed Description
A critical public health need exists for improved prognostic tools to distinguish aggressive from slow growing prostate cancer at diagnosis, and for better support systems to guide patients in decision-making regarding management options. Decision support interventions that are tailored to specific clinical conditions are known to have increased patient self-efficacy, knowledge, question-asking, and satisfaction; and decreased decisional conflict, regret, anxiety, and distress. To reduce the risk of over-treatment, our team has developed individual risk prediction models that we have now integrated into our decision support intervention (DSI). Delivering such decision support intervention should increase patient knowledge and question-asking by the patient to their doctor. The decision support intervention can be delivered by telephone and or the Internet.

Eligibility Criteria
Inclusion Criteria
- •Male \>=18 years of age and newly diagnosed prostate cancer (PCa) (within 3-months).

- •English language proficient and ability to provide informed consent
Exclusion Criteria
- •Participants will be ineligible if they:
- •have pursued any active therapy for prostate cancer will be excluded;
- •are unable to read/speak English; or

Outcomes
Primary Outcomes
Decision Quality Index (DQI) scores
Time Frame: 12 months
The DQI measures patient Knowledge, Concordance, and Decision process. For each fact about prostate cancer item, a correct response = 1 point. Missing responses=0 points. Total score is calculated for all patients who complete at least half of the items and scaled from 0-100%, with higher scores indicating greater knowledge. Patients rate their goals and concerns on an 11-point importance scale from 0 (not important at all) to 10 (extremely important). These questions + one question about patient's treatment preference can be used to calculate a concordance score. Patients are asked about whether they were offered a choice, how much pros and cons were discussed, and whether the health care provider asked for their preferences. Participants get 1 point for a response of "yes" / "a lot/some.", total points are summed, then divided by total number of items for a decision making process score from 0-100%. Higher scores indicate a more shared decision making process.
Secondary Outcomes
- Memorial Anxiety Scale for Prostate Cancer (MAX-PC) scores(12 months)
- Decision Self-Efficacy (DSE) Scores(12 months)
