We define age as
* '''Integer Number of years between DOB and last birthday prior to ''or on'' admission.'''


The multi_search module in [[TMSX and MedTMS]] presents '''average age''' with four decimal places.
Usually used in aggregate form as "per location" and/or "per timeframe", e.g. by day/month/quarter/year x Ward/Unit x Hospital.  


=== Implementation ===
==Uses==
Age is actually stored as a value in  [[TMSX and MedTMS]] rather than calculated when needed.  Patient data is sent from the [[Laptop Setup | Laptop]] and is [[PDA Uploader | uploaded]] to the master [[TMSX | Critical Care]] or [[MedTMS | Medicine]] database. Calculation of age is done by the PDA uploader during appending (uploading) of sent data to master database.
===Critical Care===
Part of the [[APACHE_Scoring_table#Age_Points|APACHE II score]] where patient's age  falling under an age group(i.e. ≤44,45-54,55-64,65-74,≥75) has corresponding score


When this value is generated in [[CCMDB.mdb]] e.g. for use in the [[Overstay]] project age is implemented using a floor function.
===Critical Care QI domain===
[[QualityDomain::Understanding the population]] by showing  aggregate counts of patients per age group (i.e. <40,40-60,61-80,>80)


===Medicine===
Part of [[ALERT Scale]]  as Age and  AgexAge
==Sampling Plan / Procedure==
100 % of all patients admitted to Medicine or Critical Care
===Inclusion Criteria===
All
===Exclusion Criteria===
None
==Definition and Derivation==

*ACCESS
**CCMDB_Age = excel.WorksheetFunction.Floor(CInt(DateDiff("yyyy", DOB, Adm)) + Int(Format(Adm, "mmdd") < Format(DOB, "mmdd")), 1)
***where Birth = Date of Birth and R_Adm = Date of Admission
*SAS
**Age=floor((intck('month',Birth,R_Adm) - (day(R_Adm) < day(Birth))) / 12)
*Both formula yields the same AGE values.
*Both formula yields the same AGE values.
