Determination of Unclaimed Prescriptions at an Outpatient Department, Songklanagarind Hospital
Unclaimed prescriptions are an initial indication of noncompliance. Although the patients receive the best treatment, they may fail to take their medicines. As a result, the illness may not be relieved and this can lead to hospitalization or use of emergency services. This study was conducted to determine the characteristics and reasons for unclaimed prescriptions in a 680-bed and tertiary care center from July to October 1997. Patients' data were collected from medical records and from questionnaires that asked for the reasons prescriptions were not claimed. During the four-month period, 695 unclaimed prescriptions were identified, accounting for approximately 0.67% of all prescriptions filled. Results showed that patients least likely to claim a prescription included women, those who visited the hospital during official hours, those who had chronic disease, and those who went to see internal medicine physicians. Three most common diseases were those involving respiratory system (8.6%), musculoskeletal system (6.3%), and genitourinary system (6.0%). More than half (56.5%) were treated with the essential drugs. Neuromuscular agent was the most frequent drug class of unclaimed prescriptions, followed by respiratory agent, dermatological agent, and vitamins and minerals. Of the 695 patients, 152 patients responded to the questionnaires. Sixty-one patients indicated that they had received their medications later on and, therefore, were excluded from the analysis. Thus, 61 questionnaires were analyzed. The most important reason patients did not claim their prescriptions was cost (22.0%). The next most frequently mentioned reasons were forgetfulness (12.1%), business (11.0%), and lack of communication (8.8%). These patients need to be counseled about the importance of taking their medicines. In addition, health care providers should develop strategies to improve patient compliance with their medications.
