= NIHR !BioResource Questionnaire - frequency list =

The NIHR !BioResource questionnaire includes a section for participants to list their long-term medication.

Our initial intention was to build up a picking list for this, compiled from the answers given by participants, and add to it as the recruitment process expands.

There is a dm+d browser at http://www.ppa.org.uk/systems/pcddbrowserv2_3new/browser.jsp#product which is a good place to look up correct drug names and dose information.

Starting drop-down list should contain:

OD = omni die (every day) 
OM = omni mane (every morning) 
ON = omni nocte (every night) 
Count all the above as 1

2: BD = bis die (twice daily) 
3: TDS = ter die sumendum (to be taken three times daily) 
4: QDS = quater die sumendum (to be taken four times daily) 
5:
6: QQH = quarta quaque hora (every four hours) 

If PRN (as required) enter an estimate, such as 0.5 per day.

Since the above is quite complicated, why not just allow a number entry and present the question as "how many doses per day?"
