IMPACT2: Implications for Management of PET Amyloid Classification Technology in the Imaging Dementia(IDEAS) Trial
Study Details
Study Description
Brief Summary
The main purpose of this study is to build upon the evidence captured in the Imaging Dementia
- Evidence for Amyloid Scanning (IDEAS; NCT02420756) trial to include valuable information regarding patient-reported outcomes and physician confidence in diagnosis and management based on the Implications for Management of PET Amyloid Classification Technology (IMPACT; NCT number not yet assigned) trial design.

Detailed Description
The primary purpose of this prospective, observational study is to examine the benefit of amyloid positron emission tomography and computed tomography (PET/CT) scan in clinical practice for participants at our site that are enrolled in the IDEAS (NCT02420756) trial. To accomplish this, when a clinician has ordered an amyloid PET scan, the investigators will assess the impact of [18F]Flutemetamol PET/CT scans on 1) physician diagnosis and management as it relates to care practices and drug management, and 2) patient reported outcomes in patients evaluated in the Cognitive Disorders Clinic at the University of Utah and meeting Appropriate Use Criteria (AUC) for clinical amyloid PET/CT scans. A secondary purpose is to compare the semi-quantitative assessment of amyloid plaque burden using vendor supplied software and standard visual assessment of amyloid positivity.
The primary hypothesis is that, in diagnostically uncertain cases, knowledge of amyloid status as determined by amyloid PET/CT scans may alter patient diagnosis and management and lead to significant changes in patient and family reported outcomes. A secondary hypothesis is that vendor supplied semi-quantitative assessment of amyloid plaque positivity will be superior to standard visual criteria assessments.
Objectives
AIM 1: to assess the change in diagnosis and management, related to care practices and drug management of adult patients being evaluated for cognitive deficits and meeting Appropriate Use Criteria (AUC)
AIM 2: to assess the change of amyloid PET/ CT scans on patient-reported outcomes involving care partner confidence and satisfaction
AIM 3: to assess confidence increase through use of vendor supplied semi-quantitative software
AIM 4: to assess adherence to identified patient management related to care practices and drug management
