Agreement between admission and discharge diagnoses: Analysis by the groups of international classification of diseases, 10th revision

Background/Aim: Analysis of the agreement between admission diagnostic groups and discharge diagnostic groups of patients in the Clinical Centre in Kragujevac in the period from 01/01/2006 to 31/12/2013 on the basis of the hospitalization report. Methods: From the basic set of reports, 5% of random samples are singled out and they contained 20.422 reports. Out of the given number of reports, 18.173 hospitalization reports were complete and they have been further analyzed in the paper. Admission diagnostic groups given by a primary care doctor are compared with the discharge diagnostic groups filled out by a practicing physician in the hospital ward from which a patient is discharged. The agreement of these two diagnostic groups represents an indication of the high-quality performance of the primary care doctor. Agreement analysis is conducted using Cohen’s Kappa statistic. Results: Agreement analysis shows that the values of the Kappa coefficient for the five leading admission diagnostic groups are in the range of k=0.61 to k=0.94. The value of the Kappa coefficient for the five most common discharge diagnostic groups is in the range of k=0.55 to k=0.81. Conclusion: Hospitalization report is a reliable individual report on inpatient care and it can be used in determining the degree of agreement between the admission diagnostic groups and discharge diagnostic groups.
