Abstract
- Background: Patient and caregiver perspectives on amyloid positron emission tomography (PET) use are largely unexplored, particularly as compared with clinician views.<br />Methods: We surveyed clinicians, patients, caregivers, and dementia advocates on topics relating to an evidence-based guideline on amyloid PET use. Topic importance was rated on a 9-point scale. Patient stakeholder and clinician views were compared using the Mann-Whitney U test.<br />Results: Patient representatives (n=107) rated all survey topics as equal to or more important than clinicians (n=114) except 1 item discussing potential harms of false-positive diagnoses. Differences between patient representative and clinician populations were greatest when comparing the competing values of false-positive and false-negative diagnoses and the value of testing asymptomatic individuals.<br />Conclusions: Patients and caregivers emphasized the importance of having a dementia diagnosis and placed more value on testing and outcomes for asymptomatic populations than clinicians. This underscores the importance of research investigating the effect of amyloid PET results on asymptomatic individuals and the need for amyloid PET ordering and disclosure standards.
