Date of Birth

Date of Birth (DOB) is part of the patient demographic information that we collect.

Age

Age is part of the APACHE II score for Critical Care and MOST score used in Medicine.

We define age as

• Number of years between DOB and last birthday prior to admission.
• if someone is admitted on their birthday, do we use their previous birthday then? Boundary condition... Template:Discussion
  • an integer value is used, not a decimal value up to the admit date

The multi_search module in TMSX and MedTMS presents average age with four decimal places.

Implementation

Age is actually stored as a value in TMSX and MedTMS rather than calculated when needed. Patient data is sent from the Laptop and is uploaded to the master Critical Care or Medicine database. Calculation of age is done by the PDA uploader during appending (uploading) of sent data to master database.

When this value is generated in CCMDB.mdb e.g. for use in the Overstay project age is implemented using a floor function.

Template:CCMDB Data Integrity Checks

The minimum age allowed is 10, the maximum age allowed is 107. If the data of birth would lead to a patient age outside of this range, the CCMDB.mdb will not allow you to send.
