Background In Germany, the situation of geriatric medicine has improved sig
nificantly over the past few years. Until now, though, there was little inf
ormation available on the structure of the clinical geriatric departments.
Since this information is vital to assess whether these departments can pro
vide high-quality services, the German Federal Association of Clinical Geri
atric Departments conducted a survey among its members. The goal was to gai
n deeper insight into the structure of the geriatric acute hospitals and re
habilitation units. Methods In 1999, member institutions were mailed a stan
dardized questionnaire and all institutions (100%) returned the questionnai
re to the association's central office. To increase data quality, data were
screened and reports were generated for each institution. These reports we
re returned to the institutions which were asked to verify them. Results Th
is article shows that in 1998 acute geriatric hospitals I (n = 89), rehabil
itation units (n = 52), acute day clinics (n=45) and rehabilitation day cli
nics (n = 26) had - on average 60/60/15.3/14 beds/places and 828.15/677.3/1
64.2/125.9 patients. Occupancy rates averaged out at 88.7%/84.3%/86.4%/63.7
% and daily hospital rates at DM 401.4/322.4/293.8/243.2. Basically, all ge
riatric institutions included in this survey had a multi-professional geria
tric team. Patient-to-staff ratios for psychologists, social workers, ergo-
, physio- and speech therapists were better in day clinics than in in-patie
nt clinics and better in rehabilitation units than in acute hospitals. Geri
atric institutions mainly focused on the treatment of neurological deficits
. Most patients were admitted from other hospitals and discharged to their
private residence. Conclusions The results of this survey indicate that esp
ecially the acute hospitals are often not sufficiently staffed. Moreover, f
urther efforts are necessary to clarify the indications for and modalities
of geriatric day clinic treatment and rehabilitation. The data also show th
at a categorical distinction between geriatric acute hospitals and rehabili
tation units is not possible. However, further data collection and more det
ailed analyses are needed.
