[Study of compatibility of psychiatric diagnoses with ICD-10 diagnostic criteria using the SCAN questionnaire].
OBJECTIVE
Authors aimed at testing whether psychiatrists in their diagnostic process obeyed strict ICD-10 diagnostic criteria. Diagnoses made by psychiatrists at discharge were compared with those of SCAN ver.2.1 on admission.


METHODS
Diagnoses obtained by SCAN I-Shell program were compared with clinical diagnoses obtained by psychiatrists in the psychiatric wards according to ICD-10 criteria on 3 levels: diagnostic group (Fc), diagnostic class (Fcc), and diagnostic category (Fcc.c). Validity assessment was obtained with Cohen's Kappa coefficient, sensitivity, specificity and Yule's Y coefficient.


RESULTS
On the diagnostic group level, Cohen's kappa was 0.14-0.65, Yule's Y 0.57-0.71. Sensitivity 0.69-0.95 and specificity 0.41-0.94. In psychotic disorders group F2 kappa was 0.65, Yule's Y 0.71, sensitivity 0.69, specificity 0.94. In affective disorders group F3 kappa was 0.31, Yule's Y 0.57, sensitivity 0.95, specificity 0.41. In neurotic disorders group F4 kappa was low 0.14, Yule's Y 0.62, sensitivity 0.95, specificity 0.50.


CONCLUSIONS
The study showed a higher level of agreement between SCAN and clinical diagnoses in the group of psychotic disorders with exception of schizoaffective disorders, and lower agreement rates in the group of affective and neurotic disorders where the number of SCAN diagnoses outweighed that of the clinical ones. It could be the result of systematic faults in the coding of diagnoses.
