Outcome | Participants | Data source | Analysis |
---|---|---|---|
Proportion given the PtDA | Men with localized prostate cancer | Clinical administrativea data (~n = 1000) | Proportion with 95 % confidence intervals for each case study |
Men’s outcomes: decisional conflict | Men with localized prostate cancer | Clinical administrativea data (~n = 1000) | Linear regression (decisional conflict) to compare those who were given the PtDA to those who were not |
Practitioner’s outcome: factors influencing PtDA use | Urologists, radiation oncologists, and nurses in prostate programs | Mailed survey (~n = 40) | Multivariable ordinal logistic regression analysis of practitioner’s reported use of PtDA with factors reported in the survey as covariates. Subgroup analysis will be done by types of practitioner (e.g., urologists, radiation oncologists, nurses) |
Health system outcomes: uptake of treatment (including surveillance) and practitioner consultations | All men with localized prostate cancer | Clinical administrativea data (~n = 1000) | Multinomial and binary logistic regression analysis of treatment uptake and practitioner consultations with receipt of the PtDA as main predictor, and adjusting for patient demographic and clinical characteristics. |
Factors influencing PtDA implementation | Key stakeholders in each program | Individual interviews (~n = 30–40) | Thematic analysis guided by the Knowledge to Action Framework |
