[Geriatrics in Bavaria-Database (GiB-DAT): Conception, structure and results of implementation (part I)].

In the year 2000, a database was implemented in Bavaria, covering the majority of geriatric clinics. Benchmarking statistics are generated in quarterly periods and scientifically analyzed. Actually, 41 of the 57 geriatric clinics in Bavaria participate in the project 'Geriatrics in Bavaria-Database' (GiB-DAT). For geriatric rehabilitation, the coverage is 82.4%. In addition, all 7 geriatric day clinics participate; thus, a total of 24,000 cases are documented each year. Therefore, GiB-DAT is the largest database for geriatric rehabilitation in Germany and Europe. To make documentation more effective and easy, new software (GERIDOCTM) has been generated which is integrated in the process of daily treatment. GiB-DAT offers good data quality, especially concerning completeness of items. This manuscript describes conception and construction of GiB-DAT and identifies differences compared to the Geriatric Minimum-Dataset (GEMIDAS), a nationwide geriatric database in Germany.
