2.4. Inadequate adherence cause
Patients’ reasons for inadequate adherence were classified into one or more of the following categories: economic (nonadherence due to lack of financial resources that prevented medication purchase or follow-up by the patient); forgetfulness ( failure to remember medication taking, as well as complex medication schedules); prescription loss (paper medical prescription mislead granted by an institution provider), physician-related (lack of therapy regimen explanation or inadequate information regarding treatment importance); prescription misunderstanding (patient was aware of the established medications and their importance but changed schedules, dosages, medications, or did not follow prescription by removing or adding other medications); and patient preference (inadequate adherence was the result of their decision despite having knowledge of its importance and that the physician made an adequate explanation of their treatment).
