Abstract
AIMS/INTRODUCTION: It is a reality that there are still many diabetic subjects who suffer from serious complications, but there are few statistics of severe eye complications such as vitrectomy or blindness and diabetic foot including amputations in Japan. MATERIALS AND METHODS: To determine the status of medical examination, consultation, and the actual practice for diabetic foot, retinopathy, and nephropathy, we conducted two surveys on diabetic subjects under treatment by the local physicians in Asahikawa area or in the nationwide diabetes-specialized facilities, respectively. RESULTS: A total of 3649 diabetic subjects responded to the questionnaire from 35 clinics/hospitals in Asahikawa area. Sixty-five percent of the subjects had a routine eye examination at least once a year, but 29% of them interrupted or never attended eye examination. Besides, only 37.2% of subjects had received ankle-brachial index (ABI) test as a useful screening for diabetic foot. The nationwide survey found that 1,273,103 diabetic subjects were undergoing treatment in 472 diabetes-specialized facilities. There, lower extremity amputations accounted for 0.23% and revascularization accounted for 0.64% of the subjects. However, outpatient foot care and dialysis preventive outpatient services were offered only in 77.3% and 66.5% of the facilities, respectively. Furthermore, we found a lower availability of ophthalmologic treatments even in some of the specialized facilities. CONCLUSION: We considered that interruption and non-attendance of eye examinations were a barrier to prevent severe retinopathy. Our results also suggested that some of the specialized facilities may be inadequate in their efforts to detect and prevent these complications.
