    Traduction en anglais : Longitudinal analysis of hospital utilisation based on claims data of the German sickness funds.


    To investigate which of the routinely collected claims data from the German « Legal sickness funds » on hospital utilisation may be used in addition to that prescribed by the legislator.


    We used claims data to study a cohort of sickness fund beneficiares who were insured during the complete year 1992 (n=81309).

    Six utilisation parameters, using the number ofcases and in hospital days overall as well as diseases specific (i.e. readmission rates, in-hospital days per person with [at least] one hospital stay) were calculated.


    There are 88 persons with (at least) one hospital stay, 116 hospital cases and a total of 1306 in-hospital days per 1000 insured persons in the study cohort.

    The average hospital days per person (14.8 days) are ca. 30% higher than the average length of stay (11.2 days).

    Hospital utilisation increases with age.

    Hospital stays associated with ICD-239 (neoplasms of unknown origin) resulted in a higher than average number of hospital days in total although the mean length of stay is not above the average.

    This is due to a high readmission rate.

    Hospital stays associated with elective surgical procedures have a high prevalence rate but a low readmission ratio and short length of stay.


    The parameters related to insured persons, cases and specifically personal parameters of hospital utilisation allow a detailed analysis of hospital care.
