Infectious Disease Scenariofor Community Health
Info Exchange

• A three-year old presents for the first time to a
  pediatric care provider with a one-week history
  of cough without fever. The coughing occurs in
  prolonged episodes of several minutes, followed
  by vomiting on three occasions.
• Unknown to the pediatric care provider, twelve
  cases of pertussis (whooping cough) have been
  reported in the county over the past month.
• The childs guardian brought no vaccination
  record to the visit.
• (Note pertussis can be transmitted by
  respiratory spread (breathing contaminated air).
  Even previously vaccinated adults with trivial
  symptoms can be infected and infect others for up
  to three weeks unless treated.
• Contemporary public health practice is to
  routinely vaccinate all children under age 7,
  isolate known and suspect cases until treated for
  5 days and isolate contacts to known cases until
  treated for 5 days.)

QuestionsInfectious Disease Scenario

• How might a local health information exchange
  help the pediatric care provider make the right
  diagnosis?
• How might a local health information exchange
  help public health authorities learn about
  possible new cases of pertussis?
• How might a local health information exchange
  enable providers and guardians access to
  information on past immunizations?
• What information-sharing/communications
  modalities already exist that could support
  better outcomes in such cases?
• What information-sharing/communications
  modalities are on the horizon that could support
  better outcomes in such cases?
• What obstacles to such information sharing exist,
  and how could they be addressed?

Chronic Disease Management Scenariofor Community
Health Info Exchange

• Healthcare providers in the Technology Valley
  metropolitan region have completed a health
  information exchange that assembles, for each
  participating patient, historical information on
  diabetes-related laboratory information (e.g.,
  Hemoglobin A1C), prescriptions, and medical and
  surgical procedures (CPT codes).
• Local public health departments in Technology
  Valley offer community nutrition programs, home
  visiting nursing programs, and community health
  information through face-to-face groups, public
  health clinics, printed and electronic media.
• Patient information is not shared between the HIE
  and the public health client management
  information systems. Summary population data
  from the HIE (which can be displayed
  geographically and by other demographic
  characteristics) have not been shared with local
  public health agencies.
