Patient-reported outcomes (PROs) and PRO measures (PROMs) are often used to help clinicians and researchers understand patients' personal concerns, feelings, experiences, and perspectives following the implementation of an intervention. Notably, PROs and PROMs can inform health systems, health policy, and payers on the utility of clinical genetic testing based on each patient's personal values, perspectives, and potential health behaviors subsequent to testing. In this topic synopsis, we discuss the underexplored role of and implications for PROs and PROMs following genetic testing for familial hypercholesterolemia (FH), an autosomal dominant genetic disorder of cholesterol metabolism that can lead to highly premature fatal and nonfatal myocardial infarction and stroke. We also discuss why the use and consideration of patient perspectives, via PROs and PROMs, are critical to the process of optimizing patient care across various FH treatment contexts. As expert clinician groups consider the latest evidence when establishing recommendations for FH genetic testing, there is a ripe opportunity for clinicians and researchers to explore the value and utility of PROs to inform and possibly improve care for patients diagnosed with FH.
