Quality of type 2 diabetes management in general practice is associated with involvement of general practice nurses.

Abstract

To assess whether involvement of general practice nurses in type 2 diabetes care in Danish general practice is associated with improved adherence to national guidelines on regular type 2 diabetes monitoring, and with lower HbA1c and cholesterol levels in the type 2 diabetes population. The study was an observational study soliciting questionnaire data from 193 Danish general practices and register data on 12,960 patients with type 2 diabetes (age range 40-80 years) from a diabetes database and a laboratory database. Clustering was addressed in the analyses. Practices with well-implemented nurse-led type 2 diabetes consultations and practices with no nurse(s) employed differed according to the mean proportions of patients whose HbA1c was measured (6.4%-points: 95% CI: 1.5 to 11.4), and the mean proportions of patients whose HbA1c was ≥ 8% (-3.7%-points: 95% CI: -6.7 to -0.6). Small non-significant differences were found in the cholesterol analyses. Compared with practices with no nurse(s) employed, the quality of diabetes management was generally higher in terms of that HbA1c was measured according to the guidelines in a larger proportion of the diabetes population and the proportion of patients with an HbA1c level ≥ 8% was lower in practices with well-implemented nurse-led type 2 diabetes consultations.
