Objectives
• At the conclusion of this session, the participant will be able
to:
• 1. discuss the scope of polypharmacy and it's significance
to the health and quality of life of the geriatric population
• 2. discuss outcomes for inappropriate medication use in
older adults
• 3. identify barriers and facilitators to safe medication use
in older adults
• 4. identify strategies for interdisciplinary management and
safe use of medications in older adults using high alert
medications and other tools
Why Older Adults?
• Growing population----over 40% of
hospitalized patients 65 and older
• LARGEST CONSUMER OF MEDICATIONS
• More vulnerable to errors and drug-related
problems (chronic disease, aging changes)
# 1 KEEPING UP WITH NEW
DRUGS ON THE MARKET
 Internet Drug Sales
 Direct marketing to
consumers
 Are new $ drugs always
better?
 Long term effects versus
clinical trial results
 Media/marketing role (94%
of 3000 MDs reported
relationship with Pharm
industry)
# 2 INCREASED FOCUS ON ADVERSE
EVENTS CREATING TUG SAFETY/QUICK
DRUG APPROVAL
# 3 VALUE PLACED ON NONPHARMACOLOGICAL TREATMENTS
 Non-pharmacological
sleep protocols
 Supplemental pain
interventions
 Need-dementia based
model of care for
behavior problems in
persons with dementia
 Drugs should not always
be the first line of
treatment
# 4 AGING CHANGES
• Increase in body fat and
decrease in lean body mass
• Decrease in total body
water
• Decrease in GFR and CO
• Decrease plasma protein,
esp Albumin
• Decrease in liver mass and
blood flow may slow
metabolism
• Most changes lead to
increased toxicity

# 6 MEASUREMENT
CHALLENGES
•
•
•
•
•
•
Unlikeliness of an event in a given pt or disease
Absence of prodromal signs before the drug exposure
Consistency with drug properties and injury
Recurrence of event with rechallenge of drug
Event goes away with discontinuance of drug
Known relationship with underlying mechanism of drug
action
• Related toxicity seen in vitro on animal studies
# 7 ATTITUDES &
KNOWLEDGE IN AGING
• In a study of Nurse knowledge of delirium utilizing
standardized case vignettes---41% recognized hypoactive
delirium and 32% said they would call the physician to
medicate the patient (Fick, Hodo, Lawrence, & Inouye,
2007)
• Only 21% recognized delirium superimposed on dementia
and 26% said they would call for a medication
# 8 MULTIPLE PLAYERS
# 9 GERIATRIC EDUCATION
• Shortage of geriatric trained
professionals
• Reduction in geriatric funding
• Growing population of older adults
• Earlier pre-clinical diagnoses of disease
• Costs and benefits of treatments
• Consumer knowledge and literacy
# 10 APPROPRIATE

Beers Criteria
Original author Mark Beers et al 1990
Explicit criteria (and list) of
medications to AVOID in older adults.
Should have a safer alternative.
Widely cited and used medication
criteria
Loved and hated all at the same time!
Expert Panel
• 16 potential participants with national
expertise in geriatric pharmacology,
geriatric medicine, psychopharmacology,
acute and longterm care
• Our response rate was 75% (12/16) and
all that responded agreed to participate
5 Parts In Survey For Experts to
Consider
1) Old Criteria medications to avoid with
and without diagnoses
2) New drugs out since criteria last
updated
3) New evidence since last update
4) Medications added by Panelists in first
and second rounds

• anticoagulants, narcotics and opiates, insulins,
and sedatives
• Patients 65 and older more likely to be
harmed by high alert medications even when
used appropriately

METHODS
• We examined association of DRPs with
administrative data for analyzing strength of
association, specificity, temporality, and biologic
plausability of the DRPs in N=960 older adults in MCO
• Claims data were collected for three years on all
identified cases with dementia and each included age,
gender, medical diagnosis for each claim (ICD-9 code)
and prescription drugs (NDC).

RESULTS
– Over 79% of PWD in this sample were on a CNSactive medication during the three-year time period
(period prevalence).
– 62% were on a PIM as defined by 2003 Beers
criteria (Fick et al, 2003)
– 55.7% were on a COMBINATION of CNS drugs over
the 3 year period

What our data has shown so
far
1) Inappropriate medication use, CNS-active
and sedative hypnotic medications are
common in older adults and in PWD
2) Poor outcomes are associated with the use
in PWD
3) Medications are often the first line of
treatment for behavioral problems in PWD
4) Nurses and physicians often do not
recognize delirium
General Principles for Reducing Harm
from High-Alert Medications
• Hospitals and other care settings should employ
the following principles of a safe system:
• 1. Design processes to prevent errors and
harm.
• 2. Design methods to identify errors and harm
when they occur.
• 3. Design methods to mitigate the harm that
may result from the error.
Interventions for improving drug
use in older adults
• Many physician based interventions in managed
care—focus on only 1 player
• DADE project state of New York
• Challenges in addressing medication use in
acute care for older adults
• Most are based on computer alerts—must also
have culture change

CONTINUOUS FEEDBACK
Future of Drug Use In Older
Adults?
• Broader interdisciplinary view
• Drug burden scales incorporating dosages and
cumulative affect
• Genetic targeting-personalized databases
*Gurwitz et al 2006
• Interdisciplinary approach and incentives
• IT-Electronic alerts, interventions, and
education
PATIENT CARE PEARLS
• Limit the overall number of medications
• Use of non-pharmacological approaches first
• Better use of technology to reconcile meds
• Good Communication between disciplines
• Continual assessment of Mental Status and
Function
• Special care at transitions and assess HOME
• Consider problem of underuse as well
NON-PHARMACOLOGICAL
ALTERNATIVES
• Sleep protocol (see McDowell, Mion, Inouye, 1998)
• Therapeutic Activity Program---http://www.atratr.org/dementiapractice/recommendations.htm
• Mobilize early and often
• Vision and Hearing aides
• Remove and camouflage invasive devices
• HELP--http://elderlife.med.yale.edu/public/publicmain.php
TAKE HOME PEARLS
• Appropriateness as DYNAMIC concept
• We must include more older adults in
clinical trials and develop system for
reliable post market data
• Geriatric education valued and funded
• Shared incentives and communication
among players
• Organization/SYSTEM culture change
