THE VALUE OF KNOWING A PATIENT’S AMYLOID STATUS
>60%
Patient management changed in over 60% (4159/6905) of patients with MCI 90 days after amyloid PET (compared with pre-PET plan).1
Design: The Imaging Dementia—Evidence for Amyloid Scanning (IDEAS) study: A single-group, multisite longitudinal study assessing the association between amyloid PET and subsequent changes in clinical management among Medicare patients who have MCI or dementia. Amyvid was one of three tracers used in this study.1
Objective: This study aimed to determine if amyloid PET is associated with subsequent changes in the management of patients with MCI or dementia of uncertain etiology with post hoc analyses to determine change in diagnostic confidence. The results of the reported analyses should be interpreted as exploratory.1
An additional 90-day follow-up appointment was required after the initial PET scan. At this visit, the referring specialist completed a post-PET case report to document the implemented patient management plan as well as record any changes in their diagnosis and their diagnostic confidence.1
Population: A total of 946 dementia specialists at 595 US sites enrolled 16,008 patients in the IDEAS study between February 2016 and September 2017. Of these, 11,409 had complete information and were included in the final analysis data set.1
33.3%
A negative amyloid PET scan led to cognition-specific drug discontinuation in 33.3% (n=6) of previously treated patients.2
65.6%
A positive amyloid PET scan led to 65.6% (n=61) of previously untreated patients starting cognition-specific medications.2
Design: The Incremental Diagnostic Value of Amyloid PET with [18F]-Florbetapir (INDIA-FBP) study is an open-label, multicenter study involving 18 Alzheimer's disease (AD) evaluation units from Northern Italy.2
Objective: This study aimed to investigate the incremental diagnostic value of amyloid PET with florbetapir F 18 and examine routine clinical assessments of patients being evaluated for cognitive impairment.2
Population: A total of 228 consecutive adults with cognitive impairment with prescan diagnostic confidence of AD between 15% and 85%.2
