  • 1. William G Flick DDS, MPH Clinical Associate Professor University of Illinois Chicago Oral Maxillofacial Surgery Public Health Implications of the Illinois Dental Anesthesia and Sedation Survey for 2006 Sponsored by the Illinois Dental Society of Anesthesiology, and the Illinois Society of Oral Maxillofacial Surgeons
  • 2. Dental Anesthesia and Sedation The Lighting Rod for Public Attention !
    • Probably the single most scrutinized area of dental practice
    • Adverse outcomes create a disproportionate amount of media attention
    • Public concern regarding the, appropriateness, regulation and even the necessity of such services.
  • 3. Example of Media Attention
  • 4. The Challenge
    • Sustain the Public’s confidence
    • Ensure public safety
    • Maintain availability of office based anesthesia and sedation services
    • Promote the cost effectiveness of office based anesthesia.
  • 5. Multi Faceted Pro Active Response
    • Governmental Sector, Regulatory Agencies
    • Input From Organized Dentistry
    • Research to Generate Data that Reflects the Scope, Utilization and Outcome
    • Continual reassessment of public health policy regarding services.
  • 6. Illinois Dental Practice Acts Regulates Practice of Anesthesia by Dentists
    • No permit required for Anxiolysis, Nitrous Oxide Analgesia
    • Permit A– Conscious Sedation, includes oral and parenteral
    • Permit B- Deep Sedation and General Anesthesia
  • 7. Illinois Dental Anesthesia and Sedation Survey for 2006
    • A follow up survey of an earlier study conducted in 1996 among all dental practitioners in Illinois with a Type A permit for conscious sedation or a Type B permit for deep sedation/general anesthesia.
    • The survey describes the scope and many aspects about the sedation and anesthesia services offered in dental offices in Illinois.
    • The information is useful to the profession, public health policy advocates and regulatory agencies.
  • 8. Issues addressed in the survey :
    • age, years in practice
    • type of practice
    • ACLS training
    • peer review, accreditation
    • staffing
    • type of sedation drugs used
    • intubation in office
    • number of cases treated
    • morbidity, mortality
    • use of capnography
    • AED use
    • Dantrolene in emergency kit
  • 9. Why an update of survey at this time?
    • 10 year anniversary
    • permit for oral sedation in Illinois
    • Anesthesia CE for license renewal
    • New inhalation agents, ie. Sevoflurane
    • Interruption of Brevital supply
    • Generic forms of Propofol and Versed
    • Mandatory AAOMS peer review
    • Dental anesthesiology specialty
    • Anecdotal reports of anesthesia related deaths in dental office
