  • Then, where is the closest defibrillator?
  • What does all this mean?-Sudden cardiac arrest is a common problem.-AEDs can improve survival rates -Philadelphia needs help-Sudden cardiac arrest is a time sensitive issue.
  • What if you weren’t here for the summer or a Penn student?What if you were in Center City?What if you were in an unfamiliar area?Would you know where to look?
  • People don’t know what AEDs are. -often had to show people a picturePeople don’t know where AEDs are even in buildings that do have them. Manufacturers don’t know where they are. -AEDs get moved
  • For places that already have AEDs, are these AEDs accessible?
  • Rural vs. urbanLow income vs. high incomeFinancial contraints
  • Draw attn to the variability in aed placement across block groups
  • Canvassing creates a gold standard
  • Locating AEDs to Improve Community Access

    1. 1. Locating AEDs to Improve Community Access By Alison Leung Mentor: Raina Merchant, MD, MS
    2. 2. If someone in this roomwere to collapse, become unresponsive and stopbreathing, what would you do?
    3. 3. Chain of Survival
    4. 4. Background: What’s an AED? AED is an automated external defibrillator Can shock and restart the heart if it stops beating normally Provide life-saving audible CPR instructions
    5. 5. Background: Why do we need AEDs? Every year, 300,000 Americans suffer from out-of- hospital cardiac arrest. One study estimates that an AED is used in 8% of out-of-hospital cardiac arrests.  In Philadelphia, an AED is used approximately 1-2% of out-of-hospital cardiac arrests. Rapid defibrillation in some cases can significantly improve chances of survival from <1% to >50%. The chance of survival decreases 7-10% each minute in cardiac arrest.
    6. 6. Where are the closest AEDs to CPC?
    7. 7. AEDs around CPC 3 3 1 1 1 1 1 2 1
    8. 8. What are the problemsregarding AED access?
    9. 9. Lack of knowledgePeople don’t know what AEDs are, nor do they know where they are.
    10. 10. AccessibilityFor places that already have AEDs, are these AEDs accessible?
    11. 11. Distribution Rural vs. Urban Low income vs. High income
    12. 12. Financial AEDs are expensive.
    13. 13. How can we address these issues? Project goals  Raise AED awareness  Find out where AEDs are and build a map for the general public and 911 dispatchers! Map for 911 Launch the Validate dispatchersCanvassing MyHeartMap Contest and Challenge Entries smartphone app
    14. 14. Methodology: Canvassing 2 teams of 2 summer students collected information in Philadelphia County about AEDs Door-to-door asking if buildings have installed AEDs Developed a survey  Type of building  Time spent in building  Number of people contacted  AED location  Has the AED ever been used?  Is the AED readily visible to visitors?
    15. 15. Where we canvassed Used block groups (U.S. Census) Canvassed 12 block groups in Philadelphia Selected block groups with the most jobs because of more public locations
    16. 16. Preliminary ResultsProcess of Canvassing No patterns regarding which buildings have them and which buildings don’t.  Many large buildings do not have them, yet some small retail businesses do have them. It often requires contacting more than one person to find out whether or not a building has an AED. Searching for AEDs is time consuming  Ranged from 1 minute to 1 hour for a building
    17. 17. Preliminary Results % of bldgs Number of bldsBlock Group #Jobs with AEDs per block group Confirmed AED use1 43655 14% 171 32 22874 32% 63 33 21847 4% 150 14 17834 9% 101 25 12456 26% 23 06 12325 5% 324 17 11824 5% 82 0Total 142815 9% 914 10

    19. 19. Upcoming Events  Release of contest rules  Release of the app  Promoting contest and AED awareness  Flashmob  Lipdub
