Among the 4,114 MyPHRSC registrants, there were 972 unique illness/condition diagnoses in the MyPHRSC data set. The ten most common diagnoses were: metabolic disorder, high blood pressure, cataract, skin lesion, disorder of soft tissue, joint pain, osteoarthritis, disorder of back, chest pain, and disorder of esophagus. Because so many unique conditions, illnesses, and symptoms existed among the beneficiaries in the sample, NORC, in conjunction with ASPE, selected eight chronic conditions for closer examination. The selected conditions were: high blood pressure, coronary artery disease, heart failure, diabetes, chronic obstructive lung disease, asthma, cataract and osteoarthritis. These eight conditions were selected because of their prevalence in the Medicare population. A 2007 Medicare Payment Advisory Commission (MedPAC) report cited high blood pressure, coronary artery disease, heart failure, diabetes and chronic obstructive lung disease as among the most prevalent conditions within the Medicare population. Two conditions--cataract and osteoarthritis--were added based on a list developed by CMS of conditions that cause high health burdens and represent the highest cost for Medicare. There was also effort to coordinate the selected conditions with those chosen for the managed care PHR evaluation, resulting in the inclusion of asthma in our analyses. Among the eight selected conditions, high blood pressure was the most common diagnosis for MyPHRSC registrants.
