Are Type 2 diabetic patients offered adequate foot care? The role of physician and patient characteristics

Abstract 

In the context of a nationwide outcomes research program on Type 2 diabetes, we investigated physician and patient practices related to foot care. Patients filled in a questionnaire investigating whether they had received information about foot care, how often they had had their feet examined in the last year, and how often they usually checked their feet. Analyses were adjusted for patient case-mix and physician-level clustering. Overall, 3564 patients were recruited by 125 diabetes outpatient clinics (DOCs) and 103 general practitioners (GPs), of whom 6.8% suffered form lower limb complications. The presence of foot complications was correlated with insulin treatment, cigarette smoking, low levels of school education, and the presence of other diabetic complications. More than 50% of the patients reported that they had not had their feet examined by their physician and 28% referred that they had not received foot education. Patients with lower levels of school education and income, as well as overweight individuals, were less likely to receive foot education. Physicians tended to perform foot examination more often in males, low-income patients, those with foot complications, and those treated with insulin, but not in patients with the highest risk of foot complications, that is, those with diabetic neuropathy or peripheral vascular disease (PVD). GPs tended to perform foot examination less frequently than diabetologists do. Foot self-examination was not performed by 33% of the patients. Those individuals who had received foot education or had had their feet examined were more likely to check their feet regularly. A substantial proportion of Type 2 diabetic patients is not offered adequate foot care, even in the presence of major risk factors for lower limb complications. Patient knowledge and practices are strongly related to physicians' attitudes.
