Background: We investigated whether older patients are disadvantaged compar
ed to younger patients on admission to a psychiatric clinic. Method: Using
odds ratio and Mantel-Haenszel statistics, the null hypothesis is tested of
whether patients over sixty-five years old who do not live in the sector o
f the catchment area of a psychiatric clinic have the same changes of admis
sion as patients over sixty-five who live in this sector. Results: Older se
ctor patients and younger non-sector patients are preferentially admitted c
ompared to older non-sector patients. The odds ratio of the particular grou
ps deviated highly significantly from 3.83, thus refuting the null hypothes
is. Conclusion: Younger patients are preferentially admitted by the clinica
l psychiatrist.
