Rewriting a Rx recalculates the quantitiy even when a quantity was previously set


an existing drug in the list of medications with non parsable instructions
eg Ativan 1mg 1 po qhs sparingly M:28 R:0

Steps to Reproduce

renew the drug
the previous quantity appears briefly (28) and then gets overwritten with the parsed quantity (in this case it will calculate 0)
Ativan 1mg 1 po qhs sparingly M:0 R:0

Expected Result

Ativan 1mg 1 po qhs sparingly M:28 R:0

Observed Result

Ativan 1mg 1 po qhs sparingly M:28 R:0

Additional Comments

if the calculated quantity from parsing the instructions is 0 please do not overwrite a non zero pre-existing quantity

We just upgraded our Oscar to version 19 RC2-9~1000 and found either a change or a problem in OscarRx.

When you try to ReRx medication it used to fill in the Qty and Repeats from the previous prescription.

What we found in Oscar 19 in a small number of patients tested, that in some cases the Qty did not fill in the amount from the previous prescription, but the Repeats did. In the small testing sample, this did not happen to all ReRx attempts. However, I could not find a pattern to why some did and some didn't (or I might have missed something).

Is this a new feature of Oscar 19? If yes, what makes it appear or not.

Any information is much appreciated.

Thank you,

Luis Strauch

To clarify the EXPECTED RESULT is that the existing quantity gets reperscribed and that it never gets replaced with 0. To whit lets not reparse the script and just renew.

This is also happening when using a favourite drug as well:

I have a simple fix I am testing and will commit today if passes testing.

Better in build 1013, if you add from the prior list a single Rx renewal (or just add one at a time)

BUT its still not fixed if you add a number of Rx at the same time the recalc still triggers and gives you a 0 to replace the previous Rx’d amont
