Laura O. Wray, PhD, Director of Education, VA Center for Integrated HealthcareDavid A. Hunsinger, MD, MSHA, Medical Director, Binghamton VA Outpatient Clinic
Collaborative Family Healthcare Association 13th Annual ConferenceOctober 27-29, 2011 Philadelphia, Pennsylvania U.S.A.
Session #F4 - 20October 29, 201110:50 AM
Faculty Disclosure
We have not had any relevant financial relationships during the past 12 months.
Need/Practice Gap & Supporting Resources
• Costs of care for patients with dementia are significantly greater than costs for similarly aged
• Significant impairment in medical adherence can occur long before dementia is recognized
• Rates of detection of dementia in primary care are low• Undiagnosed dementia is a missed opportunity to improve
quality of care and quality of life for our older patients• First step in improving care is to increase recognition
Objectives
• Describe the experience of VA Upstate New York Veteran’s Integrated Health Care System (VISN 2) in using an electronic
medical record based system to identify Veterans to be screened for dementia
• Review guidelines for recognition of dementia• Discuss how medical and behavioral health providers can
work collaboratively to address this challenge
Expected Outcome
Attendees will be able to discuss how common risk factors can be used to improve the detection of dementia in primary care
Dementia Recognition in Primary Care (PC)
USPSTF: “Insufficient evidence to recommend for or against screening”
25-40% cases recognized: typically when moderately impairedWhat delays dementia diagnosis?`
Provider• Time constraints
• Absence of family informant• Provider attitudes: Dementia is
untreatable
Patient• Agnosagnosia
• Acceptability of screening• Family discomfort with raising
concerns
Highlights of American Academy of Neurology Guidelines
Know and Share the 10 Warning Signs
Be alert to cognitive impairment– Know and use a
brief mental status measure (example: Mini-Cog Borson S, et al. Int J Geriatr Psychiatry. 2000; 15: 1021-1027.)
Clinical Criteria for AD are reliable
Include routine evaluation of:– CBC– Glucose– Depression Screening– Thyroid Function– Serum electolytes– BUN/creatine– Serum B12– Liver function
Ten Warning Signs of AD1. Memory loss that affects job skills
2. Difficulty with familiar tasks
3. Problems with language
4. Disorientation to time and place
5. Poor or decreased judgment
6. Problems with abstract thinking
7. Misplacing things
8. Changes in mood or behavior
9. Changes in personality
10. Loss of initiative
VISN 2 RAPID* Goals:
Promote early recognition of cognitive impairment and diagnosis of dementia
Provide access to comprehensive assessment for Veterans who screen positive for cognitive assessment
Offer education and support to caregivers
Provide access to dementia care management
*RAPID = Recognizing and Assessing Progression of cognitive Impairment and Dementia

RAPID Case Finding Approach:Use of Dementia Red Flags1. Electronic Medical Record:
– Age (Over 70)*– And one or more of the following:
2 or More ER visits in past yearHistory of CVA Taking more than 1 anticholinergic medication
2. Behavioral Health Assessment Center (BHAC) performs cognitive screen
3. Dementia Care Manager calls veteran and family informant and reviews medical record– Medication adherence problems– More than 7 prescribed medications– Agitation– Multiple falls in past year– More than 2 hospitalizations– Attending office visit with caregiver– More than 2 missed appointments in past year– DX of Diabetes + hypertension + CAD + hyperlipidemia
Adapted from the work of Callahan, Boustani, Unverzagt et al., Ann of Int Med (2006)
RAPID Screening CallsMonthly call lists – clinical reminder technology– Adaptable to adjust # of patients to be
screened
Blessed Orientation Memory and Concentration Test (BOMC)– Validated for use over the phone– Routinely used as part of BHL software– New introduction script created– Score = Total Errors; Range = 0 - 28– ≥10 is suggestive of dementia
RAPID Case-Finding StrategyCall List Criteria– Primary Care appointment within the coming month– No prior dementia diagnosis– Veterans 70* years and older
And Either– One or more anticholinergic medication
OR– History of CVA
OR– Two or more ER visits in last year
BHAC calls veteran– Positive BOMC (11 or greater) referred to DCM– Negative BOMC healthy brain questions and feedback about
preserving memory via lifestyle
Program Evaluation Methods - Sample
All VISN 2 Veterans aged 70 and over
At least 1 appointment at any VISN 2 medical center primary care FY07 - FY09
Exclusions:– Diagnosis of dementia in FY05 – FY07– Prescription for Cholinesterase Inhibitor of
NMDA receptor antagonist– Missing any data for any risk factor
Example: PHQ-2 (2,881 Veterans)
Program Evaluation Methods - Sample
Sample Categorization– RAPID Eligible Veterans
70 yrs and older and any of the following:– 2 or more ER Visits– History of CVA– 1 or more anticholinergic medications
Within RAPID Eligible:– BOMC + Veterans: Score 10 or greater– BOMC – Veterans: Score of less than 10– Unscreened Veterans: no evidence of a RAPID
screening call in EMR
Program Evaluation Methods
Index Date: to track time to diagnosis– Unscreened Group: first medical appointment
after 10/1/07– Screened Group: date of the RAPID call
Incidence of New Dementia Diagnosis– 1st occurrence of visit encounter coded for
dementia following Index Date
Within RAPID Eligible Veterans, is a BOMC+ associated with a new dementia diagnosis?

Tobacco
Alcohol Use (Audit-C)
Depression (PHQ-2)

Risk Model for Incidence of New Dementia Diagnosis
SummaryAge, ER use, and History of CVA continue to be strong risk factors.
Depression is also an important predictor– Older adults with PHQ+ or in MH treatment
should be considered for dementia screening
Program activities following a BOMC+ associated with a 5x increase in new dx–Supporting identification of dementia
can improve PC recognition rates
