HST counts the number of pills to assess the medication adherence. The number of pills or doses taken were divided by the number of pills or doses prescribed, multiplied by 100 (expressed as a percentage). A good adherence is considered when the result of counting is between 80% (20% loss of doses/pills) and 110% (the patient consumes 10% more doses/pills) of doses/pills prescribed.
