Data Management

This set of articles (still in process of being written) seeks to discuss the fundamental processes of data management.


The Hospital Information System (HIS) is designed to enable the gathering and storage of data and then make them available as information for primary and secondary use. Primary use refers to the use of data or information for performing clinical work (i.e. caring for the patient). Secondary use refers to use of data outside the scope of actual care of the patient for reasons such as audit and research. For both, data about a single patient or a group of patients are presented in raw (primary form) or derived (secondary) form. The term primary and secondary use must be differentiated from Primary (Raw) data and Secondary (derived) data.


Data management is a set of activities consisting of:

  1. Data generation
  2. Data acquisition (collection, gathering, capture)
  3. Data transfer
  4. Data storage
  5. Data extraction
  6. Data analysis
  7. Data interpretation
  8. Data presentation
  9. Data dissemination

  1. Dr. Salleh,
    This is great work for all the articles you’ve shared. Am currently studying for my MSc in Health Informatics and also got an Internship job with a hospital today. They task me to look at their HIS application and see if I can get it to work better for them. I have no experience with HIS but I think with your materials I feel very confident to have a great time with the hospital. Just to find out, do you have a Youtube channel on these lectures? Great work once again.


    1. Dear Maurice,
      I am glad you find my site useful. I am currently reviewing many of the articles that I wrote nine years ago besides introducing new articles. Appreciation from people like you is my motivation.
      It would be good if you can walk around the hospital and observe how various functions and processes (SOP, Workflow) are conducted in comparison to what I proposed in my articles. It is also good to interact by asking questions. Too often (I notice), workers in IT sit in their office and not venture out to see what is happening in the real world.
      I am thinking of putting my material on Youtube but I find the process kind of tedious. I will need to find assistance.



    1. Thanks for visiting my site and reading my articles.
      Usually presentation is made after analysis but data can also be presented without analysis as raw data with or without some sort of arrangement. Analysis involves grouping, sequencing and comparison. It usually uses of simple descriptive statistics (graphs, histograms, pie charts) or more advanced statistics. I have Powerpoint presentations I made for a course. I will share them with you after I have edited them.
