As the use of remote clinical management methods increases with advancements in technology and general necessity, there is a need to evaluate the efficacy of these methods to optimize patient safety and improve clinical care. Rens et al. aimed to determine the accuracy of a home-based 6-minute walk test (6MWT) as compared with a clinic-based 6MWT to evaluate frailty in patients with cardiovascular disease (CVD).

Methods: iPhones and Apple Watches (series 3) with the VascTrac research app were provided to 110 ambulatory participants scheduled for vascular or cardiac procedures at the Palo Alto VA Hospital. Participants completed the inclinic 6MWT before their medical intervention, 2...
