    Patient and caregiver assessment of the benefits from the clinical use of amyloid PET imaging
    (Wolters Kluwer, 2018-01) Mustafa, Rafid; Brosch, Jared R.; Rabinovici, Gil D.; Dickerson, Brad; Carrillo, Maria C.; Glazier, Brad; Gao, Sujuan; Tierney, Martha; Fargo, Keith N.; Austrom, Mary G.; De Santi, Susan; Clark, David G.; Apostolova, Liana; Neurology, School of Medicine
    INTRODUCTION: Few studies to date have explored patient and caregiver views on the clinical use of amyloid positron emission tomography (PET). METHODS: A 7-item questionnaire assessing patient and caregiver views (510 total respondents) toward amyloid PET imaging was advertised broadly through alz.org/trialmatch. RESULTS: We received 510 unique responses from 48 US states, 2 Canadian provinces, the Dominican Republic, and Greece. Both patients and caregivers indicated that they would want to receive amyloid imaging if offered the opportunity. Over 88% of respondents had a positive response (∼10% with neutral and 2% with negative responses) to whether amyloid PET should be offered routinely and be reimbursed. Such information was felt to be useful for long-term legal, financial, and health care planning. Respondents identifying with early age cognitive decline (younger than 65 y) were more likely to explore options for disability insurance (P=0.03). Responders from the Midwest were more likely to utilize information from amyloid imaging for legal planning (P=0.02), disability insurance (P=0.02), and life insurance (P=0.04) than other US regions. DISCUSSION: Patients and caregivers supported the use of amyloid PET imaging in clinical practice and felt that the information would provide significant benefits particularly in terms of future planning.

    Response to depression treatment in the Aging Brain Care Medical Home model
    (Dove Medical Press, 2016) LaMantia, Michael A.; Perkins, Anthony J.; Gao, Sujuan; Austrom, Mary G.; Alder, Cathy A.; French, Dustin D.; Litzelman, Debra K.; Cottingham, Ann H.; Boustani, Malaz A.; Department of Biostatistics, School of Public Health
    OBJECTIVE: To evaluate the effect of the Aging Brain Care (ABC) Medical Home program's depression module on patients' depression severity measurement over time. DESIGN: Retrospective chart review. SETTING: Public hospital system. PARTICIPANTS: Patients enrolled in the ABC Medical Home program between October 1, 2012 and March 31, 2014. METHODS: The response of 773 enrolled patients who had multiple patient health questionnaire-9 (PHQ-9) scores recorded in the ABC Medical Home program's depression care protocol was evaluated. Repeatedly measured PHQ-9 change scores were the dependent variables in the mixed effects models, and demographic and comorbid medical conditions were tested as potential independent variables while including random effects for time and intercept. RESULTS: Among those patients with baseline PHQ-9 scores >10, there was a significant decrease in PHQ-9 scores over time (P<0.001); however, the effect differed by gender (P=0.015). On average, women's scores (4.5 point drop at 1 month) improved faster than men's scores (1 point drop at 1 month). Moreover, both men and women had a predicted drop of 7 points (>50% decline from baseline) on the PHQ-9 at 6 months. CONCLUSION: These analyses demonstrate evidence for the sustained effectiveness of the ABC Medical Home program at inducing depression remission outcomes while employing clinical staff who required less formal training than earlier clinical trials.

    Targeting Functional Decline: Results from the Alzheimer’s Disease Multiple Intervention Trial
    (ACP, 2017-02-07) Callahan, Christopher M.; Boustani, Malaz A.; Schmid, Arlene A.; LaMantia, Michael A.; Austrom, Mary G.; Miller, Douglas K.; Gao, Sujuan; Ferguson, Denisha Y.; Lane, Kathleen A.; Hendrie, Hugh C.; Psychiatry, School of Medicine
    Background Alzheimer’s disease (AD) results in progressive functional decline leading to loss of independence Objective To determine whether collaborative care plus two years of home-based occupational therapy delays functional decline Design Randomized controlled clinical trial Setting Urban public health system Patients 180 community-dwelling subjects who were diagnosed with AD and their informal caregivers Interventions All subjects received collaborative care for dementia. Intervention patients also received in-home occupational therapy delivered in 24 sessions over 2 years. Measurements The primary outcome measures was the Alzheimer’s Disease Cooperative Studies Group Activities of Daily Living Scale (ADCS ADL); performance based measures included the Short Physical Performance Battery (SPPB) and Short Portable Sarcopenia Measure (SPSM) Results At baseline, there were no significant between group differences in clinical characteristics; the mean MMSE for both groups was 19 (SD=7). The intervention group received a median of 18 home visits from the study occupational therapists. Both groups declined in ADCS ADL scores over 24 months. At the primary endpoint of 24 months, there were no between group differences in ADCS ADL scores (mean difference 2.34, 95% CI −5.27, 9.96). We were also unable to definitively demonstrate between-group differences in the mean SPPB or SPSM. Limitations The results of this trial are indeterminate and do not rule out potentially clinically important effects of the intervention. Conclusions We were unable to definitively demonstrate whether the addition of two years of in-home occupational therapy to a collaborative care management model slows the rate of functional decline among persons with AD. This trial underscores the burden undertaken by family caregivers as they provide care for persons with AD and the difficulty in slowing functional decline.
