56
Q

central challenges

A
  • plethora of disconnected, inherited systems:
  • accounting
  • planning and logistics
  • pt administration
  • x-ray, lab systems, MR systems…
  • low degree of information flow between organizations and service providers:
  • a pt will roam between organizations and between doctors, with different illnesses and problems
  • do we have the necessary means of communication to provide the pt with effective health services?
  • get a SECOND opinion! -> too much information -> doctors may have different opinions
  • relevant clinical information is not available for the right person at the right time and place
  • relevant clinical knowledge is not available in the health information systems
  • leads to people doing the same tests over again
  • low quality of information: inconsistencies and errors
  • the pt is not a part of the information flow: no control or participation
57
Q

key elements of informatics

A
  • acquisition- gain information, capture data taking care to strive for quality (accurate, timely, reliable, complete)
  • storage- save data so that it can be retrieved (trash bin will store data but its hard to retrieve) -> cloud
  • communication- Data needs to be moved from point of collection to storage, for analysis, and finally to point of use (this may a very short distance and time where data is used near collection point or may be widely separated points.)
  • manipulation- data usually needs to be manipulated in some way, combined with other data, aggregated, or compared -> makes the data useful
  • display- How can the data be best displayed so that it can be easily understood and acted upon?
58
Q

decisions determine data

A
  • understanding diseases and their treatment
  • develop and test treatments
  • ensure right pts receive right intervention
  • service delivery, performance assessment
  • this all ties into health records - how is it doing what its supposed to do, how does it benefit the doctors
