Calculating the age of a patient Download PDF
1 Age
- To derive the age from the date of informed consent and date of birth variables, the below code can be used:
var a = BRTHDAT;
var b = ICDAT;
var ret = '';
//Checking for the null conditions
if(a != null && b != null)
{
ret = 0;
//Calculating AGE
ret = b.getFullYear()-a.getFullYear();
ret--;
if(a.getMonth() < b.getMonth())
{
ret++;
}
if(b.getMonth() == a.getMonth() &&
a.getDate() <= b.getDate())
{
ret++;
}
return ret;}
