Placebo-controlled treatment trial of depression in elderly physically ill patients.
OBJECTIVE
To determine the response of physically ill elderly depressed patients to treatment.


METHODS
Acute geriatric medical inpatients with depression, randomly assigned to an 8-week double-blind placebo-controlled trial of fluoxetine.


METHODS
Response rate as defined by the 17-item Hamilton Depression Rating Scale.


RESULTS
Eighty-two patients entered the trial; 62 patients (all those who had completed at least 3 weeks of treatment) were included in the efficacy analysis. Forty-two completed the full 8 weeks (21 in each group) with response rates of 67% in the fluoxetine group and 38% in the placebo group. No significant difference was found between the responses of the two groups (p = 0.12). There was a trend for results in the fluoxetine group to continue to improve with time. On secondary analysis those patients with serious physical illness who completed 5 or more weeks (N = 37) showed a significant improvement in mood if treated with fluoxetine (p = 0.02).


CONCLUSIONS
The main benefit of antidepressants is to approximately double the chances of recovery. This trial showed the response rate of the fluoxetine treated group was increased by a factor of 1.8 over the placebo group in an 8-week period. The presence of physical illness, often severe and/or multiple, did not reduce the effectiveness of the medication, which was well tolerated overall. Those with serious physical disease responded significantly better to drug treatment; this will require further work. Psychological support was also considered to be important.
