Where We Are Today - Repository
• Patients: 2.6 million• Visits: >10 million since 1996 with
archives going back to 1979• Visit diagnoses, locations,
procedures, providers, insurance• Lab procedures: 16 million with 130
million results (to 1989)• Radiology procedures reports: 5.7
A procedure assesses the effect of an antibiotic which disrupts aphysiologic function which is a process of an organism which has an
attribute (sensitive/resistant).

MedLEEHISTORY OF PRESENT ILLNESS: This 67 year old with a history of syncope in 1987 and 1989. She reported that she was evaluated both times and the work up was negative for any specific etiology. On the day of admission she reports having one episode of severe diarrhea and she was having increasing abdominal discomfort with flatulence and one episode of vomiting. When she returned to the bath room to move her bowels again she felt light headed and called for a family member. The family member reported that the patient was unconscious at that time and was placed in bed and recovered within 1-2 minutes. there was no history of any precipitating shortness of breath, chest pain or any seizure activity. At the time the patient was seen in the hospital she already felt fine.
