Abstract

Objective: To evaluate understanding of pictograms on how to take oral tablets among illiterate Thai Muslim patients and to study their effects on medication compliance, recall of instruction for use and satisfaction towards drug labels of such patients. Method: The study consisted of two parts. The first focused on the evaluation of understanding of the pictograms in 126 illiterate Muslim patients. The tested pictograms reflected 10 most frequent instructions on how to take oral tablets found in Su-ngaipadi hospital. Pictograms in the study were developed by Bovornrat Angsuwattanakul and Sanguan Lerkiatbundit. The researchers showed 4 randomly selected pictograms to each subject, and interviewed his/her understanding of the pictograms. The subjects in second part of the study were illiterate Muslim patients to whom physicians prescribed new item(s) of drug. The subjects were randomly allocated into control group (n=61) with traditional labels and experimental group (n=61) with both traditional and pictogram labels for their new drug item(s). At the patients’ subsequent visit, the researchers assessed their medication compliance, recall of instruction on drug use and satisfaction towards labels. Medication compliance was assessed by pill counting. Recall and satisfaction were evaluated by interviewing the subjects. Results: In the first part of the study, more than 93.9% of the subjects correctly interpreted 10 pictograms in all aspects including number of tablets to be taken, frequency, number of times per day for drug taking and times relative to meals (before or after meals), satisfying the American National Standard Institute (ANSI) criteria for comprehensibility. The results of second part of the study showed that experimental group had a significantly higher level of compliance, recall on drug instruction and satisfaction towards received labels compared to those of control group. Conclusion: Health care institutions could apply the pictograms developed by Bovornrat Angsuwattanakul and Sanguan Lerkiatbundit to their illiterate Muslim patients. The pictorial labels are comprehensible by this group of patients and able to increase medication compliance, recall of instructions and patient satisfaction towards pictograms.
