
“CENTRICITY” = Centralized records
Many kinds of records = integration
Faster access to records
Support diagnoses
Reduce errors, save lives
Control information explosion, save
$$$
Trends





Aging population and poor diet
Need for skilled nurses/doctors
Improved IT / Information explosion
Centralization
Security and privacy
Insurance/Legal/Gov’t regulations
Budgets becoming thin
I/P/O/F/S analysis: INPUTS
 Prescriptions, allergies
 x-ray and EKG results
 Patient data:
 family history, tests, visits, insurance,
billing
 IV pump data, temperature
 Heart rate, etc.
PROCESSING
 System sign-in, analyze patient
history
 Find test results (searching,
organizing)
 Integrated system (workflow)
 admit to treat to discharge.
 Monitor patient
 Check for prescription side effects
 Insurance benefit and Cost analysis
OUTPUT






Patient info screens
Treatment DECISIONS
Screens for each function, reports
Bills
Print or display test results
Transmit data/tests to other
organizations?
FEEDBACK
 Beat national standards:
 time to perform angioplasty
 Average length of stay
 Number of errors
 Performance
 Less staff
 Less legal and insurance costs
 Since nurses closer to patient: less falls
 Survey patients and system users
 Error and exception reports generated by system
 Monitor costs for ROI

Government (Medicare, Medicaid)
Insurance co’s
Legal system
Staff, patients
GE and other software providers
HMOs
Attribute Analysis:Accurate
 No errors, recorded correctly
 Scanners track medications
 Doctor enters prescription, sent to
pharmacy


Required for correct diagnoses
Should data check on input – ranges
Better than handwriting
No duplication of information
Complete
 No omissions
 Every item required for some
function/goal


Support diagnoses
Insurance and billing
Patient and family history
Medications and tests
Economical
 Save Doctor/Nurse/Staff time – fast
search
 Easy to enter or merge data into
system
 Remove paper records, file clerks
 Quicker diagnoses
 Reduce errors – less legal liability
Flexible
 Support many users/functions
Registration desk
Billing
Insurance
Easy to change/add new data types:
tests
 Adapt easy to new regulations,
enhancements
 Many kinds of devices: PDA s, terminals,
etc.

System available 24X7
Can be depended on
No glitches
Correct data displayed every time
Updated by trusted users
Relevant
 Just data to support task at hand




Billing, insurance, diagnosis
Display in correct format or detail
Don’t display other data
Clean out/archive old data
Simple
 Easy to interpret by staff for given
task
 Standard code system
 Easy to use / find info
Timely
 New data entered quickly into system
 Tests, medications, procedures
 New data available to use immediately
 System runs quickly, even with many
users
 Find patient info quickly
 Recognize adverse reactions quicker
Verifiable
 Can check with other sources
 Login Audit trail (track who made
changes)
 Maybe sign-off by two staff members
 Connect to other databases (ins. Co.)
 Compute other values (e.g., medication
doses)
 Nurse checks vital signs
Accessible
 Convenient for staff member needing
access
 Terminal stations
 Pocket PC/ PDA – wireless
 Access to outside
organizations/specialists
 No rummaging through paper files
Secure
 Access to data only as needed by
function
