Consumer Product Post-Market/In-Consumer Product Post-Market/In-Market SurveillanceMarket Surveillance
• What is it????
The processes whereby manufactures, regulators, health professionals, the public at large, and others monitor the performance and experience related to a given products life-cycle in the open market.

Post-Market/In-Market SurveillancePost-Market/In-Market Surveillance
• “The absence of reliable evidence of risk should not be mistaken for reliable evidence of the absence of risk”
Regulations and SafetyRegulations and Safety
The question to ask:
Are there systems or processes in place to identify safety issues through methods other than serendipitous discovery?
andHow do you acknowledge the varying levels of
quality and integrity of typical “spontaneous reports” received regarding any consumer product
Post-Market/In-Market SurveillancePost-Market/In-Market Surveillance
• Helps identify intended and unintended use patterns that may potentially contribute to Adverse Events
• Allows assessment of how the product performs by itself or in the presence of other products or substances
• Helps insure that “unique” populations are not adversely affected
• Should also help define a relative “Safety profile”

CPSC Monitoring SystemsCPSC Monitoring Systems
National Electronic Injury Surveillance System (NEISS):
• Surveys 100 ER’s selected as a nationwide probability sample of all 5,300+ U.S. Hospitals with ER’s
• Designed to provide the Commission with evidence of need for:
- a product recall- a public awareness campaign- a product safety standard

CPSC Internal Monitoring SystemsCPSC Internal Monitoring Systems
Consumer Communications: Individual Reports Involving Death or Injury
• Results in CPSC investigation into injury allegations
• May include on-site, face-to-face interviews and analysis of the product involved as well as medical records related to the injury

Adverse Event Reporting Systems Utilized Adverse Event Reporting Systems Utilized by Industry: :by Industry: :
FDA Monitoring SystemsFDA Monitoring Systems
• FDA MedWatch
- Depends on either the patient or a Healthcare Practitioner to identify an effect, identify a suspected cause, question a relationship and report it to a “governmental” body
- reporting is typically a “one-way” street (not designed to engage the caller and provide “clinical advice”)
Other External Surveillance Databases, Other External Surveillance Databases, Systems or ServicesSystems or Services
Medical Literature (human & animal)
• More in-depth reports with medical details on the injury
• Often lacking on “circumstance” info*** (focused on what was done after the exposure)
• Often serves as basis or support for “pro-active” regulation (animal or human data)
Other External Surveillance Databases, Other External Surveillance Databases, Systems or ServicesSystems or Services
• Media Clipping Service
• Surveys/reports of death or injury in the lay press that involves consumer products
• Product Liability Claims

“TESS”“TESS”
• Designed to allow documenting of all inquiries made to the poison center
• Basic set of data elements collected
• Provides a good overall picture of the “marketplace”
• Very “Sensitive” for certain types of reports but not necessarily “specific”

Minnesota Poison Prevention FindingsMinnesota Poison Prevention FindingsY2KY2K
• For all pediatric cases, 97.6% result in non-significant outcomes (<=minor effects) and 91.1% of cases result in no reported adverse effects. These outcomes are achieved with fewer than 5 patients receiving specific therapies other than decontamination.
• Of all pediatric cases, 666(3.0%) received specific decontamination therapy other than simple dilution/irrigation such as syrup of ipecac or activated charcoal. (The lack of need for specific interventions may be the result of previously cited Minnesota data reporting that more than 55% of exposures from all routes including all reasons are “taste/touch” or mucous membrane types of exposures. These types of trivial exposures represent 71% of all “ingestions”.)

• Additional Considerations
“Duration”vs.
“Intensity of clinical effects”
Evolution of the PROSAR ModelEvolution of the PROSAR Model
• Strongly influenced by national Product Stewardship efforts by Industry
- Responsible Care
- Responsible Distribution
- ProductCare
• Also influenced by evolution of “standard of care” as the model proliferated (consumer expectations)
Product StewardshipProduct Stewardship
• CSPA – ProductCare Vision
To promote the production and distribution of safe and effective formulated products that provide desirable benefits for household, commercial, institutional and industrial customers and consumers, and their families, pets and their environment.

• In-Market Support, Incident Evaluation and Follow-up
– Principle 5
• We will support dissemination of safety related product information regarding routine use of our products that is accurate, complete and in context to the inquiry or concern
• When product-related incidents occur, we will have systems in place to minimize adverse effects, assist our consumers/customers and provide needed information

Data Collection:• Information system and data collection tools based on basic
subset of information fields
• Basic subset captures both TESS data elements and EPA data elements.
• Proprietary “Case Manager” further individualizes data fields depending on the client and the Industry
• Heavily focused on documenting events surrounding the exposure, product specific details, other conditions affecting product use

PROSAR IPC Incident Monitoring SystemsPROSAR IPC Incident Monitoring Systems
Case Analysis and Incident Severity Assessments:
• Not designed to determine “relatedness”
• Based on a “consistency” rating (eg. Likelihood that based on all available factors, exposure outcome and severity appears to be either consistent, inconsistent, or indeterminable, with the known toxicologic/safety profile
• Proprietary “Case Manager” further individualizes data fields depending on the client and the Industry
PROSAR IPC Incident Monitoring SystemsPROSAR IPC Incident Monitoring Systems
Surveillance, Analysis, and Benchmarking:
• Benchmarking is provided through an automated data analysis system:
PSI (PROSAR Safety Index)
PROSAR Safety IndexPROSAR Safety Index
• Designed to help identify when to “take a closer look”
• Analytical tool to aid in identifying products that fall outside of their normal safety profile
• Based on the total number of “significant outcomes” compared against all symptomatic incidents involving a given product or class of products for a given time period
• Initially calculated at the following levels:
– Individual product
– Company
– PROSAR(also allows normalizing with product sales
data)
Future Levels of Incident EvaluationFuture Levels of Incident Evaluation
• Next level of Incident Assessment:
“Registry” approach to follow-up Product Surveillance
The SAS Initiative (Safety Assurance Surveillance)
Responding to a “serious” eventResponding to a “serious” event
• Action is typically dictated by:
- type of incident
- supporting documentation
- existing regulatory reporting requirements
- ability to investigate, verify, and add definition

Strengths/Limitations of SpontaneousStrengths/Limitations of SpontaneousReported DataReported Data
Strengths Strengths
• Monitoring for Sentinel Events:
– Critical Mass increases likelihood of discovery
• Hypothesis Generation:
– Background noise vs. emerging issue
– Aids in Design of Research?
• Generation of Safety Profile:
– Sufficient “Penetrance”?
– Insure representative sample relative intensity
LimitationsLimitations
• Outcome Severity Classifications– Some symptoms not amenable to clear-cut
classification– Indirect vs. Direct Effects– Physiologic vs. Psychologic S/S
• Assessment of Causation/Relatedness– Data does not lead to determination of “cause and
effect” relationship– At best may suggest an Epidemiological Association
• Under-reporting/Over-reporting– reporting of “real” vs. “perceived” threats– Media and promotion– Possible “link” not recognized
Limitations Limitations continuedcontinued
• Accuracy and Report Quality
– Voluntary vs. Mandatory
– Spontaneous Reports Rigorous Prospective Clinical Research
– Objective vs. Subjective Data
– Translation of layman’s symptom descriptions into complex medical terminology (i.e. paresthesias, numbness, tingling, peripheral neuropathy)
– Second hand reporting
– Hidden agenda’s
Implications for the LSRO ProjectImplications for the LSRO Project
I. Metabolife Analysis -- Outstanding Issues:
Report quality and integrityAbility to verify individual incidentsAbility to verify exact product(s) involvedLaboratory confirmationHidden Agenda’sCollection of data in a systematic formatNormalizing for product sales(eg. DEET)Independent verification of informationAbility to follow-up at this late date
Implications for the LSRO Dietary Supplement Implications for the LSRO Dietary Supplement AER ProjectAER Project
II. Advising on a appropriate model of Post-Market Surveillance for Dietary Supplements:
• Must differentiate between “ingredients” vs. “products”
• For AER/Surveillance…..No one system will suffice: All likely reporting avenues that patients, consumers, and healthcare professionals will use to request or report information must be cultivated for maximum input
• Mandatory vs. Voluntary Reporting for Manufacturers
