Abstract
BACKGROUND
National and international medical societies have published guidelines and recommendations pertaining to the diagnostics and monitoring of chronic kidney disease in patients with type 2 diabetes mellitus. Consistency and implementation in daily clinical practice are rarely reported.
OBJECTIVE
This article provides an overview on recommendations as a reflection of the global state of the art and assesses the implementation in daily practice in Germany, which was collected via a representative questionnaire.
MATERIAL AND METHODS
The current guidelines were compared with respect to the consistency of parameters, frequency of testing and recommendations for nephrological referrals. The results were then compared with the survey responses to estimate the level of their implementation in daily practice in Germany.
RESULTS
According to the recommendations the estimated glomerular filtration rate (eGFR) and the urine albumin to creatinine ratio (UACR) should be tested at least once per year in all patients with type 2 diabetes. In cases of more severe kidney impairment (above Kidney Disease:Improving Global Outcomes, KDIGO, stage 3b with eGFR < 45 ml/min/1,73 m2) or albuminuria (from stage A2), more frequent measurements and nephrological referrals are recommended; however, different threshold values and frequencies are recommended. The responses from the questionnaires indicate that eGFR is tested annually in 96.5% of all cases and albuminuria is tested in 77.2% of cases. An eGRF triggered referral to a nephrologist is implemented by 19.6% of all nonnephrological practitioners, albuminuria triggered referrals are implemented in the majority of cases.
CONCLUSION
Measurement of eGFR is the established standard in Germany. Potential improvement was found in albumin measurement, the frequency of testing and the time point for nephrological consultation. All guidelines emphasize the benefits of interdisciplinary cooperation.
