Open Patient-0.xml in any text editor. What is the HL7 data standard for this file?

Load a file using first three steps from Usage instructions from https://www.npmjs.com/package/blue-button :

Patient-0.xml. Use command doc.data.demographics and provide a screen shot of the information displayed.

Patient-1.xml. What is the code and code system used to encode the first vital sign? Use doc.data.vitals[0] and look at properties within vital.

Answer the following questions by parsing all 100 files. We strongly recommend you write a programming script to automate this (otherwise it could be very tedious):

How many patient problems are there in total across the 100 files? Use doc.data.problems.length to count number of problems of each document.

How many are receiving the medication lisinopril (code = 314076)

How many of patients are receiving lisinopril and have a problem of essential hypertension (code = 59621000)

Consider that the administration of lisinopril as a predictor of having essential hypertension. If you divide the count from c by b, what statistical measures have you calculated?
