4.1 Functional Requirements of Hospital Digital Record System

4.1.1 The software must allow input of patient data from the patient and the Physician.

                         Note. A web-based system can allow initial patient information to be gathered by a dumb terminal in office or from patient’s own computer upon Email appointment verification hyperlinked to input screen.

4.1.2 The software must request username and password for access to data, only after authentication the system will allow access.  

4.1.3 The software must require high levels of error correction and input validation.

Note. Message box prompts would require a second entry of key data fields including name, DOB, Social Security Number, medications and allergies. Doctor’s inputs will similarly prompt proper code sets for diagnosis.

4.1.4 The software must allow browsing by the physician of historical medical information of his/her patients only.

4.1.5 The software must identify the patient by a unique numeric identifier derived from a function performed on the patient’s birth date.

Note. Algorithm will be simply TODAY-BIRTHDAY = NUM & Doctor Key & Increment

(Increment will be added if duplicate number found in Database.)
