Anthony to approve his requests. Therefore, Henry sees the status “pending” while
Dr. Anthony sees two options for Henry’s request “to Approve” or “to Reject”,
along with approved request from another patient (John Smith) done earlier. If
Henry’s request is rejected, the next time he checks back into the system, he
would see the request status to go from “Pending” to “Reject”.

5.3 Access Personal Health Charts
After permission to retrieve his/her EMR from the hospital is granted by authorized
physicians, patients can then access their personal health record. To show
how the transformation was made to make the medical record easy to interpret, we
show one of the many health events retrieved visually using charts. Fig. 6 below
shows a pie chart of lab tests frequency distribution.
