Evaluation of the Personal Health Record Pilot for Medicare Fee-For Service Enrollees from South Carolina. Usage Over Time.


As noted earlier in the methods section, two dependent variables were considered.  The first dependent variable categorized registrants by a threshold of total number of logins:  never, once, or more than once.  The second dependent variable was the total number of months during the pilot in which registrants (i.e., users) logged in to MyPHRSC.  More than half of all registrants only logged in to MyPHRSC during one calendar month of the pilot.  Although these users may have logged in more than once during that single month, for the purpose of examining usage over time, one or more logins in a particular calendar month is reported simply as activity during that month.  Only 21 percent of users (n=852) accessed MyPHRSC in at least two separate months of the pilot.

Figure 5 displays the number of users who logged in at least once during each number of months.  A small number of users accessed MyPHRSC in 6 or more separate months, but no single user accessed MyPHRSC in all 12 months of the study.
