More than a half million of the elderly home health care patients received at least one psychotropic agent—.54 million patients (CI=.50–.58) or 53.52% of the elderly patients (CI=50.60–56.44). As shown in Figure 1, antidepressants were the most frequently prescribed psychotropic agents (33.51%, CI=30.71–36.31), followed by sedatives-hypnotics-anxiolytics (30.65%, CI=27.96–33.34), mood stabilizers (9.87%, CI=8.15–11.59), and antipsychotics (7.55%, CI=6.08–9.03).
