Abstract
Great heterogeneity seems to exist regarding diagnosis, therapy, and teaching of patients
with secondary adrenal insufficiency (SAI) across Germany resulting in different diagnosis
and treatment strategies. The aim of the work was to present the first national audit
on diagnosis, treatment, and patient teaching of SAI reflecting common clinical practice
in Germany. A self-designed questionnaire was sent via e-mail to all members of the
German Endocrine Society (approx. 120 centers). Returned questionnaires (response
rate 38.3%) were checked for duplicity of institutions and analyzed. Diagnostic testing
focuses on those patients with relevant risk for adrenal insufficiency. Basal serum
cortisol is mostly used as screening test. Short synacthen and CRH tests are the preferred
confirmatory tests, however, cut-off values vary due to different assays used. Patients
with radiation, second surgery, progressive disease or new symptoms are followed by
serial re-testing. Perioperative management and frequency of postoperative re-evaluations
differ among centers. Hydrocortisone is the preferred glucocorticoid for replacement
therapy, but daily doses vary considerably (10–30 mg/day). Some centers perform hormone
measurements for dose adjustment of glucocorticoid replacement therapy whereas others
rely on clinical judgement. Patients’ teaching is done in 84% of centers, but only
half of the centers include patients’ relatives. Homogeneity exists in patients’ teaching
regarding intercurrent illnesses (fever, diarrhoea). Recommendations regarding dose
adaptations in situations such as sport-activities, dental-procedures, or coughing
are highly variable. This first national audit reveals great heterogeneity among German
centers and could improve patients’ care in SAI, for example, by initiating new trials
and developing clinical practice guidelines.
