This is the "forest" view of the medical record, to give the physician a longitudinal perspective of a patient's health.
The Spreadsheet format allows the physician to quickly assess disease progression, patterns of illness and/or therapeutic efficacy.
Each visit is one row in the Spreadsheet.
The columns present the key information for a visit. The column "headings" are based on "characteristics" related to the primary diagnosis of the patient AND designed for the specific specialty and practice.
Custom columns specific for a particular patient may be appended to the standard columns.
