I am interested in sample data of real patient medical records (anonymized or demographics removed completely) for the purpose of running through NLP system - specifically diagnoses, admissions and progress notes - anything where medical terminology is used. I have no interest in linking data to specific patient types or categories - I just want the text of the notes
Ideally I would like a data such as:
10/4/2011 - 59 year old male admitted with right sided chest pain, reduced air entry and fever for 7 days. X-ray showed occlusion of right lower lobe consistent with community-acquired bacterial pneumonia.Non-smoker. 13/4/2011 - Reviewed by MO. Left leg swelling noted with some tenderness on extension - DVT suspected. No fever, SOB. BP 120/90. Ix to follow. U/S ordered. Heparin commenced.
Are there any free data sets with this sort of data? I have looked at various public data repositories such as http://www.healthdata.gov/ and https://www.nlm.nih.gov/hsrinfo/datasites.html without much luck.
