12 Widespread Press Pick-up 12

13 A Pennsylvania Story New Olympus colonoscope Looks similar to another model used by the hospital New model requires independent rinsing of water-jet channel with liquid chemical germicide Hospital mistakenly reprocessed like older model for four months! 13

14 March 2005 Headline: Monroeville Hospital urges 200 colonoscopy patients to get checked for hepatitis, HIV Headline: Callers flood hospital over colon tests April 2005 Headline: Suit claims negligence in hospital s colonoscopies 14

15 This Issue Has Been Covered Before February 28, 2003 Two Years Earlier! Same Problem 15

16 Safety Alerts Management: An Escalating Burden 16

17 Factors Impacting the Growing Numbers Major increase in the number of devices Increasing complexity of medical devices Higher level of regulatory attention Widespread coverage of recalls in the press More cautious approach by medical device manufacturers 17

23 Classification Confusion FDA s high risk medical devices (e.g., deep-brain stimulators and implantable cardioverter defibrillators) Class III FDA s low risk devices (e.g., stethoscopes) Class I For recalls Class I means there is a reasonable probability that use of or exposure to a violative product will cause serious adverse health consequences or death Class III recalls occur when use of or exposure to a violative product is not likely to cause adverse health consequences 23

24 Safety Surveillance FDA MAUDE database Voluntary vs. mandatory recalls Medical Device Surveillance Network (MedSun) program Field inspections Europe Reporting to member state Competent Authorities (e.g., MHRA) Less coordinated system New Eudamed database will improve coordination but currently is not fully utilized and has limited access 24

25 A New Regulatory Agency s Challenge Chinese examination gloves Snuck on the market through kitchen appliance stores Used for medical applications Limited product labeling (e.g., no OEM name, manufacturing date, lot number, or expiration dates) Can we allow them on the market? 25

26 Perspectives from Recent Analysis on Clinical Alarms Underreporting Some estimates suggest that the actual number of alarm-related deaths is ten-fold higher or more than what problem data shows Ability to do analytics on data is very limited I literally had to read every report (hundreds) in a recent problem reporting analysis Actual reports often don t have much information Typical language (paraphrased) - During use of device alarm did not sound and patient died 26

27 The New Technology Paradigm MDDS a new factor 27

28 Other Reporting Systems and Channels Various Ministries of Health and regulatory agencies State problem reporting systems (e.g., Pennsylvania Patient Safety Reporting System) Patient Safety Organizations Device registries (e.g., Kaiser Permanente Implant Registries) Voluntary systems (e.g., ECRI Institute) NY Times, Boston Globe, etc. 28

29 Ideal Hospital Processes for Managing Hazards and Recalls Capture complete and timely information Not always model specific Not limited to recalls Interpretation of alert contents (including recommendations) Information dissemination to relevant stakeholders Inventory matching Follow-through and reporting Analysis and oversight Did we miss anything? 29

30 Upcoming Unique Device Identification Coming soon from FDA for years (was required in FDA Amendments Act of 2007) New heavy pressure from US Congress Will require unique identifier for all devices likely in a phased approach starting with implants Potential for cost savings and safety improvements (e.g., from better identification of recalled products) Uncertain cost implications and nomenclature concerns Many implementation challenges 30

31 Device Approvals/Clearance Roles in Assuring Safety PMA vs. 510(k) Manufacturer testing Transparency and availability of data Rigor or lack thereof for clinical testing Product update challenges and delays (i.e., in getting a safer product to market) 31
