The authors measured the variation in ECT utilization rates across 317 metropolitan statistical areas of the United States and determined to what degree this variation is associated with health care system characteristics, demographic factors, and the stringency of state regulation of ECT.
Data from APA's 1988-1989 Professional Activities Survey were used to estimate ECT utilization rates for the metropolitan statistical areas.
Multiple regression analysis was used to determine the relative influence ofprovider, demographic, and regulatory factors on variation in ECT use across areas.
Among the psychiatrists surveyed, 17,729 reported treating 4,398 patients with ECT during the study period.
No ECT use was reported in 115 metropolitan statistical areas.
Among the remaining 202 metropolitan statistical areas, annual ECT use varied from 0.4 to 81.2 patients per 10,000 population.
The strongest predictors of variation in ECT use across metropolitan statistical areas were the number of psychiatrists, number of primary care physicians, number of private hospital beds per capita, and stringency of state regulation of ECT.
Rates of ECT use were highly variable, higher than for most medical and surgical procedures.
In some urban areas, access to ECT appears limited.
Predictors of variation in ECT rates have implications for expanding access to the procedure.
