A Pilot Proof of Concept, Randomized Controlled, Single-Center Study of a Decision Aid Tool for Older Patients Considering LHC as Treatment for NSTEMI

The decision aid was developed by this study group based on the International Patient Decision Aid Standards Collaboration's minimum standards for quality, and the Ottawa Framework (a process by which patients' and clinicians' decision determinants are assessed, a decision aid is developed that is tailored to these needs, and the quality of the decision-making process with the aid is evaluated). The aid then underwent an iterative feedback process with a patient advisory panel. Adjustments to format, length, and readability were made. A final feedback session occurred with three patients over the age of 70, after which point the paper decision aid was digitalized. The intervention will be delivered in-person by one of the co-investigators of the study. The intervention will occur once, prior to the patient making a final decision regarding undergoing left heart catheterization as treatment for NSTEMI. The approximate duration of the intervention is 30 minutes.
