Aims: Sufficient consultation time is important for establishing good doctor-patient relationship. We examined the factors that affect consultation length in Japanese diabetes practice.
Methods: This was a cross-sectional study performed at a diabetes clinic in central Tokyo, Japan. Regular diabetes consultations of 1197 patients with 22 physicians were analyzed. Consultation time and clinical characteristics were obtained from the electronic records. A negative binomial model, which included patient and physician characteristics, was constructed to examine the association of the variables with consultation length.
Results: Of the 1197 patients (mean age, 66; women, 25%; type 1 diabetes, 10%), the mean consultation time was 10.1min. In the multivariate model, longer consultation time was recorded in patients with type 1 diabetes, higher glycated hemoglobin (HbA1c), use of insulin injections, and use of hypnotics/anxiolytics. The consultation time was longer in patients with HbA1c of ⩾7.0 to <8.0% (⩾53 to <64mmol/mol), ⩾8.0 to <9.0% (⩾64 to <75mmol/mol) and ⩾9.0% (⩾75mmol/mol), compared to those with HbA1c of <7.0% (<53mmol/mol) with the ratios of 1.03 (95% confidence interval (CI)=0.96-1.10), 1.16 (95% CI=1.07-1.26) and 1.17 (95% CI=1.06-1.29), respectively. Body mass index was also associated with long consultation. Older and female physicians provided longer consultation.
Conclusions: Clinical consultation length in diabetes practice was associated with certain patient and physician characteristics. The findings can be used for making diabetes consultation more efficacious, which could eventually lead to the provision of the most appropriate consultation time for individual patients.
