Background
Falling duration of psychiatric inpatient stays over the past two decades and recent recommendations to tighten federal regulation of electroconvulsive therapy (ECT) devices have focused attention on trends in ECT use, but current national data have been unavailable.
Methods
We calculated the annual number of inpatient stays involving ECT and proportion of general hospitals conducting the procedure at least once in the calendar year using a national sample of discharges from 1993–2009. We estimated adjusted probabilities that inpatients with severe recurrent major depression (N=465,646) were treated in a hospital which conducts ECT and, if so, received the procedure.
Results
The annual number of stays involving ECT fell from 12.6 to 7.2 per 100,000 adult US residents, driven by dramatic declines among the elderly, while the percentage of hospitals conducting ECT decreased from 14.8% to 10.6%. The percentage of stays for severe recurrent major depression in hospitals which conducted ECT fell from 70.5% to 44.7%, while receipt of ECT where conducted declined from 12.9% to 10.5%. For depressed inpatients, the adjusted probability that the treating hospital conducts ECT fell 34%, while probability of receiving ECT was unchanged for patients treated in facilities which conducted the procedure. Adjusted declines were greatest for the elderly. Throughout the period inpatients from poorer neighborhoods or who were publicly- or un-insured were less likely receive care from hospitals conducting ECT.
Conclusions
ECT use for severely depressed inpatients has fallen markedly, driven exclusively by a decline in the probability that their hospital conducts ECT.
