Quick question: in this data, did you include patients who went to hospitals outside of HPN after seeing physicians in HPN? (I.e. patients went to a HPN physician office, for example, in the end of Y1 and in the beginning of Y2 and then went to the hospital outside of HPN)
I.e., for example, patients went to a Cleveland Clinic for a complicated heart surgery after seeing HPN physicians in Y1 and Y2. Are those patient included in the database?
Moreover, what if these patients continued going to the non-HPN inpatient hospitals in Y3 and Y4 (i.e. HospitalDays were outside of the HPN network)?
Local California patients could potentially go to Kaiser or other California hospitals after seeing physician form HPN.
If there is a Leakage in the database (i.e. patients do go to the hospitals outside of the database), is it possible to know the size of the leakage (i.e. % of cases when patients go to hospitals outside of HPN)?
Thank you for the clarification,
