You're right, I missed the "have HAD". The correct query would of course be 
"all patients with an EVALUATION.problem_diagnosis with one of a defined set of 
codes for ‘hypertension’".

A doctor making and recording a conclusion that a measurement of some kind is 
too high or too low, IS a diagnosis. A similar example using lab results would 
be a measured serum sodium level of 105 mmol/L, with the attached (from the 
lab) reference range of 115-160 mmol/L. The fact that the measurement is 
outside the reference range is an indication to the doctor that something is 
wrong, but their conclusion would be recorded as a diagnosis of hyponatremia. 
When the patient at a later point is better and a subsequent sodium result is 
back within the reference range, the hyponatremia diagnosis would be set as 
resolved.

Silje

It would not be.

Because the two assertions are not equivalent.
