Sharp decline in ECT availability and use in the U.S. general hospitals

Electroconvulsive therapy (ECT) is considered the most effective treatment option for patients with severe depression who cannot find symptom relief through antidepressant medications or psychotherapy. In a new study, researchers at Butler Hospital and Bradley Hospital in Rhode Island found a sharp decline in the availability and use of ECT in general hospitals across the U.S. The findings were published online in the journal Biological Psychiatry on October 10, 2012.

The researchers analyzed data from a nationally representative survey of US general hospitals, the Nationwide Inpatient Sample (NIS), conducted annually by the Agency for Healthcare Research and Quality (AHRQ). They took information from between five and eight million patient discharge records at 1,000 hospitals nationwide between the years 1993 through 2009 and found that the annual number of hospital stays in which ECT was administered fell 43 percent over the 17 year period, from more than 1.2 million to 720,000. Researchers also found a dramatic decline in the percentage of hospitals conducting ECT, from 55 percent to 35 percent of facilities with a psychiatric unit. The percentage of inpatients with severe, recurrent major depression treated in hospitals conducting ECT fell from 71 to 45 percent. But for depressed patients treated in hospitals that conduct ECT, the proportion who received the procedure remained stable.

"The data strongly support the impression that psychiatric units in general hospitals are discontinuing use of ECT and that this is driving the decline in the number of severely depressed inpatients receiving the procedure," said Brady Case, MD, an assistant professor of psychiatry and human behavior at Brown University and director of the Health Services Research Program at Bradley Hospital. "Growing pressures to avoid the inpatient treatment costs and length of stay associated with ECT may be one factor associated with this trend. We didn't have information on provider and patient attitudes, but as facilities cease conducting ECT, we can expect that fewer clinicians and inpatients are exposed to the option, reinforcing the turn away from ECT." Researchers also note the FDA approval of new treatment alternatives, like vagus nerve stimulation and transcranial magnetic stimulation, as possible influences.

Declines in ECT availability and use were particularly dramatic in elderly patients, a group traditionally thought to benefit most from the procedure. "Decreased availability of ECT for older patients with severe depression is of major concern, since a significant proportion of this group fails to benefit from available medication treatments. In such cases, ECT can literally be a life-saving intervention," said Lawrence Price, MD, clinical and research director at Butler Hospital and professor of psychiatry and human behavior at Brown University.
