GOAL of VA PHARMACOVIGILANCE
PROGRAM
Track and evaluate high risk and high volume agents
in veteran population
Formalize the national drug safety program with
emphasis on:
– Utilizing integrated databases as the foundation
of the VA national pharmacovigilance program
– Modernizing and enhancing spontaneous ADE
reporting
GOAL of PHARMACOVIGILANCE
PROGRAM
Track inappropriate use of therapy as part of
the national pharmacovigilance program
–
–
–
–
Polypharmacy
High Doses
Altered End Organ Function
NMEs
Conduct risk reduction efforts
Develop Active Surveillance Program
Initiate and encourage drug safety research
using national databases
VA for Pharmacovigilance/Drug
Surveillance
The VA as a resource for surveillance
and adverse event evaluation
– Older/Sicker patients
– High medication use
– Penetration of new agents is fairly rapid
– Good Information Systems
– Ongoing monitoring of outcomes in place
Adverse Drug Events in VA
Reporting, Tracking, Monitoring
Adverse Drug Event Database
– Spontaneous Reporting
– FDA MedWatch Form 3500
Allergy Reaction Tracking Package (ART Package)
– CPRS – Electronic Medical Record
– Every VA Facility
Adverse Drug Event Tracking and Evaluation Using
VA Integrated Databases
– Prescription Databases
– Inpatient/Outpatient Files
– Mortality Database
INTEGRATED DATABASES
VA National Prescription
Database
Includes data from October 1998 to present
Provides every individual Rx filled in the VA
Provides prescription days supply
Data is specific to outpatient divisions
Patient identifier is included for every Rx
Provides cost per unit for every prescription
Provides dosing instructions for each
prescription

VA Databases as a Tool
VA databases provide the mechanism for
– Medication safety projects and initiatives
– Clinical decisions
– Research
An effective tool in VA
– Monitoring exposure rate and ADEs
High risk agents
New agents
Agents with newly identified safety information
An effective tool for evaluation of appropriate use
– Safety
– Central Office and Field queries
– Other Government Agencies
Safety Evaluations
Rx databases, electronic medical record (inpatient
and outpatient files), and mortality database are
linked at patient level to monitor agents
Patients characterized by demographic, medical hx,
medication and tx variables
Patients followed for 12-24 months or greater
NME’s – tracking initiated from inception in system
and formally evaluated every 6 months
Control agent chosen
Rates of exposure and adverse outcomes assessed

Drug Safety: Lost under the street light?
A cop walking his beat one night finds a drunk on his
knees, searching for something on the street. The cop
asks the drunk, “What are you doing?” “Looking for my
car keys,” says the drunk. The cop asks, “Where did you
lose your keys?” “I don’t know,” the man answers. The
cop, a bit perplexed, asks, “Then, why are you looking
here if you don’t know where you lost your keys?”
Responds the drunk, “Because the light is better here,
under the streetlight.”
e.g. COX-2 and GI Bleeds
Where to look?
 Healthcare system that is fragmented (e.g.
Medicare, Medicaid, HMOs, PPOs).
 EU – Nationally financed healthcare
systems
 US – VHA – Integrated healthcare system
with (inpatient, outpatient, pharmacy, lab,
etc.)
Joining Data Silos for Drug Safety
What to Look For?
E.G. COX-2 GI Bleeds or Strokes and MIs
– From Case Reports
– Systems with Biological mechanisms
– Systems without Biological Mechanisms
– Proactive VS Reactive Surveillance for not
just harms but potential benefits
How to Look?
– Incidence of adverse outcomes temporally
associated with medication use (signal detection)
– More sophisticated multivariate modeling (e.g.
logistic regression, GEE, case cross-over
designs) of Medications related outcomes (drugdrug and drug-disease interactions, comorbidities
etc.)
– Expert panel review of the national Electronic
Medical Record (VISTA) of drug related cases
from signal detection phase
VHA Drug Safety Studies
PDE-5 and NION (AJO 2007)
Amantadine and CE (Cornea forthcoming)
Medication profiling (CVS, CNS, MSS) and
fractures, syncope, MI, etc. (Drugs and
Aging 2005, Br J Clin Pharm 2006, Am J
Clin Pharm 2007).
Risk Adjusted Models
(Pharmacoepidemiology and Drug Safety
2005)
When to Look? Time Frame?
IBM 3390 - 5.7 million patients, 120 million
outpatient prescriptions and outpatient care,
and perform signal detection study, short
turn around (e.g. <1 week).
Real Time Transaction Data Bases
Data Cubes and Dash Boards (SQL)
Banking Industry, Airline, etc.
Real ID ACT- The Future of Patient
Identification?
