About this trial
Many people with kidney disease also have heart disease. The procedures used to diagnose and treat heart disease (e.g., angiograms, angioplasty, or surgery) can improve symptoms and cardiovascular outcomes, but pose greater risks of kidney complications for people with chronic kidney disease. It's therefore important that patients with kidney disease and their health care providers understand the benefits versus risks of these procedures and use that information to make informed decisions regarding their health care.
Prior research done with patients with kidney disease and their health care providers has led to the develop of a decision aid designed to help doctors provide personalized information on the benefits versus risks of having a heart procedure, as well as help patients communicate their own values and preferences to their doctor. This information is crucial for shared decision making, as previous research has shown that preferences and values vary for individual patients with kidney diseases, and should be incorporated into the decision-making process for heart disease management. The decision aid, called "My Heart Care and CKD", supports shared decision-making between patients with kidney disease and heart their care providers. This trial will implement and evaluate this decision aid within cardiovascular care in a pilot trial in Canada.

Other interventionDecision aid for use by physicians and patients with CKD when deciding upon an invasive vs a conservative approach to management of coronary artery disease.
Treatment groups
Trial outcomes
Primary outcomes
Decisional Conflict Scale (O'Connor -8 question)
Patient's perceptions of modifiable factors contributing to uncertainty with their decision such as feeling uninformed, unclear about personal values and unsupported in decision making; and effective decision making such as feeling the choice is informed, values-based, likely to be implemented and expressing satisfaction with the choice.
Patient Nine-item Shared Decision-Making Questionnaire (SDM-Q-9)
Assessment of patient's perceived level of involvement in decision-making related to their own treatment.
Knowledge of Treatment Risks
Patient's knowledge of the risks of kidney failure versus a heart attack in the future associated with the treatment choices of invasive versus optimal medical management presented in the decision aid
Accuracy of Risk Perception
Whether a patient's perception of risk of the risk of kidney failure corresponds to the estimated risk of this outcome for a similar person receiving invasive management as presented in the decision aid
Secondary outcomes
Preferred Choice
The patient's inclination towards a preferred choice of treatment with invasive versus conservative management
Actual Choice
Whether invasive or optimal medical therapy was actually chosen by the patient and physician.
Adherence to Chosen Option
Whether the treatment received (invasive or medical therapy) remained the same as the initially chosen option
Decisional Regret Scale (O-Connor - 5 question)
Evaluation of feelings of dissatisfaction or disappointment following the decision, reflecting on whether the individual would make the same decision given the chance again
