Dear Experts,
I want to explore if whether a patient was given a medication or not varies depending on their individual characteristics (level 1) and those of their general practice (level 2). Level 1 covariates will be for e.g. education and age while level 2 covaraites will be practice size and urban/rural location.
I anticipate that medication use will vary depending on whether it was a nurse or GP who prescribed the medication. Ideally, I would include the GPs and Nurses as level 2 nested under their practice at level 3. However, the data I am allowed to access does not include individual prescriber id's. Instead, I will just know it was a GP or Nurse who prescribed the medication. With this limited data I cannot include the GP/Nurse prescriber as a level as GP and Nurse are the only 2 options for prescribers (not a random selection of all the possible prescribers.)
Is there any way for me to include the Nurse/GP prescriber information in my model? For each practice there will be Nurses and GPs prescribing medicatons.
