Data  Knowledge
• Data

• Information

• Knowledge
The Healthcare Process:
      • Gather Data



    • Interpret Meaning



      • Make decision
Process of hypothesis generation and refinement
Decision Taking
• Decision taken via etiology
 diagrams, Decision trees or
 expert computer systems.

• Use of the quantifiable notion of
 ‘Utilities’.

• Quality v/s Length of Life
Medical datum and data
• Medical datum is any single
 observation of a patient, data is plural
 of datum.

• A number of datum make up data.
 BP:120/80 mm of Hg (data or datum?)

• Importance of having a sound data
 model.
4 Elements of medical datum
1) Patient in Question

2) Parameter to be observed

3) Value

4) Time of observation
Various Types of Data
•   Narrative
•   Textual
•   Numeric
•   Device inputs
•   Drawings
•   Photographs
Peculiarities of Medical data
• Typical phrases like RRR / TWNL /
 NAD

• Different meanings in different
 contexts
  eg: M.I may mean different things
 in different cases/ contexts
Weakness of Traditional Record Keeping


•No Linkage

•Difficult Chronology

•Redundant

•Inefficient
Medical Data used by
• All Stakeholders in the healthcare
  delivery in clinical settings (admin/
  physicians/ finance, etc)

• Research and analysis/ New eHealth
  Products

• helps create Guidelines for EBM

• Governments, NGOs

• Clinical research
Important Terms
•   Sensitivity
•   Specificity
•   Incidence
•   Prevalence
•   Odds, Risk
•   Likelihood ratios
Calculating decisions
                              LR= Likelihood Ratio
• LR+ = TPR/FPR

• LR- = FNR/TNR

• Predictive value of tests

• Calculating value of decision at each
 fork
Data Sources
•   Clinic records
•   Hospital records
•   Disease registers
•   Medical literature
•   Web based databases
•   Survey reports
