[Differences in the extent of diagnostic procedures after acute stroke in patients treated in departments of neurology, internal medicine and geriatric medicine].
OBJECTIVE
In Germany, data about variations in acute stroke treatment between different facilities are lacking. The aim of the present study was to compare the extent of diagnostic procedures for acute stroke between departments of neurology, internal medicine, and geriatric medicine.


METHODS
Stroke patients admitted to hospitals cooperating within the Westphalian Stroke Register between January 1, 2000 and December 31, 2001 were analyzed. Forty-two hospitals participated in the study including 24 departments of neurology, 13 of internal medicine, and 5 of geriatric medicine. The register is based on a standardized data assessment including sociodemographic and clinical characteristics of the patient, in the acute phase, as well as diagnostic and treatment procedures, complications, and status at discharge. The performance of brain imaging, Doppler, and echocardiography was defined as diagnostic standard for diagnosis and etiological classification of ischemic stroke.


RESULTS
A total of 12,232 stroke patients were included. Mean age was 72 years, 49 % were men. In general, diagnostic procedures were administered more often in neurological departments compared to departments of internal or geriatric medicine. In all participating hospitals, the application of diagnostic techniques was less frequent in older patients. The defined diagnostic standard was performed more often in those neurological departments providing acute stroke unit services compared to neurological departments without stroke unit services.


CONCLUSIONS
Our study detected variations in the extent of diagnostic procedures in acute stroke between different medical disciplines. However, further studies are required to clarify whether a more frequent performance of diagnostic techniques yields relevant therapeutic consequences.
