Abstract
Background Questionnaire surveys were conducted to investigate physiciansʼ and patientsʼ perceptions of informed choice(ICh)and a once-weekly oral hypoglycemic agent(OHA)in the treatment of type 2 diabetes(T2DM). Methods Patients with T2DM aged 20 years and older who were prescribed OHAs other than a once-weekly OHA were included in the questionnaire survey. Physicians treating more than 5 patients with T2DM each month were also included in the survey. The target number of questionnaires was set to 800 for the patient survey and 200 for the physician survey. Results Data from 806 patients with T2DM and 200 physicians were analyzed. Of the patients, 75.6% were male, the average age was 58.5 years and the average duration of diabetes was 12.4 years. The percentage of patients who“almost never miss a dose”was 7.5% from the physiciansʼ responses, but 55.2% from the patientsʼ responses. According to physiciansʼ responses, 51.4% practiced ICh, while the patientsʼ responses showed only 23.1% experienced ICh. Furthermore, according to the physiciansʼ responses, the average percentage of patients who wished to change to a once-weekly OHA even with just one drug was 43.0%, while the average of patientsʼ responses was 82.9%. Conclusions Physicians and patients were found to have different perceptions of various issues, such as ICh and a desire for once-weekly OHA. ICh, in which physicians share information about treatments with patients and patients choose their treatment, may reduce the cognitive gap between physicians and patients and help improve patient satisfaction in the treatment of T2DM.
