Screening and diagnosis of diabetic polyneuropathy in clinical practice: A survey among German physicians (PROTECT...

We sought to obtain detailed information on the procedures and appraisal of screening for and diagnosing diabetic sensorimotor polyneuropathy (DSPN) in clinical practice.

This cross-sectional survey included 574 physicians from 13 federal states across Germany who responded to a tripartite questionnaire.

The vast majority of the respondents reported to screen for DSPN at least once a year (87 %), while 65 % reported to examine the feet of DSPN patients at least twice a year. However, only 28 % and 20 % of the respondents used questionnaires and scores to assess the severity of neuropathic symptoms and signs, respectively. The rates of participants reporting that they do not use a standardized testing procedure were 58 % for pressure sensation, 62 % for pain sensation, and 54 % for thermal sensation. The rates of respondents reporting that they do not deploy a standardized assessment were 41 % for vibration sensation, 73 % for pressure sensation, 77 % for pain sensation, and 66 % for thermal sensation. Half of the physicians oriented themselves towards clinical guidelines when diagnosing DSPN.

Despite relatively high screening rates, the willingness to implement both standardized testing procedures and assessment and to follow guidelines is low among physicians when screening for and clinically diagnosing DSPN.
