Table 2. Additional psychometric properties of patient-reported outcomes supporting their use in routine clinical care. KCCQ: Kansas City Cardiomyopathy Questionnaire; SAQ: Seattle Angina Questionnaire; SF: short form.

Actionability	When information from the designated measure is useful in informing how to modify treatment.	While largely a consequence of the interpretability of a PRO, a key advantage of disease-specific PROs is that by directly measuring the severity of symptoms or limitations from a particular disease, there are often treatments than can be offered (or care escalated) for either severe symptoms/limitations or acute worsening. For example, worsening symptoms in heart failure might trigger better blood pressure control or more diuresis, whereas worsening angina might support more aggressive antianginal therapy or coronary revascularization.
Feasibility	To be practical to use in clinical care, it is essential that the PROs be as brief as possible while still maintaining the requisite psychometric properties outlined above.	Example(s): Efforts to reduce PROs—such as the SF-36 to 12 items, the SAQ from 19 to 7 items, or the KCCQ from 23 to 12 items—are intended to capture as much psychometrically sound information as possible in as few items as are necessary.
