Psychosocial stressors, physical illness and the spectrum of depression in elderly inpatients.
OBJECTIVE
To describe all elderly patients hospitalised with principal and secondary diagnoses of depression, and to determine whether a relationship can be demonstrated between psychosocial stressors, physical illness and type of depression.


METHODS
A retrospective chart review of elderly patients admitted to a general hospital psychiatry ward over a 7-year period with principal or secondary diagnoses of depression was undertaken. Four broad diagnostic categories of depression were used: major depression, psychotic depression, minor depression, and organic depression. Chief outcome measures were: number of medical diagnostic categories, presence of psychosocial stressors, global clinical improvement, and length of stay.


RESULTS
Of 228 patients admitted with depression (194 principal diagnoses and 34 secondary diagnoses), 100 had major depression, 47 psychotic depression, 48 minor depression and 33 organic depression. Psychiatric comorbidity occurred in 70%, about half of which was due to organic brain syndrome. Patients with psychotic depression had the fewest medical problems and those with organic depression the most, while patients with minor depression had the highest rate of family and marital problems, comorbid personality dysfunction and suicide attempts. Patients with psychotic depression had the longest admissions, while those with minor depression had the shortest. Overall, 89% showed significant clinical improvement.


CONCLUSIONS
Elderly inpatients have a wide spectrum of depressive disorders with different psychosocial, medical and treatment profiles. Future studies of depression in old age should include all patients with clinical depression.
