Objective: The authors' goals were to determine the frequency and dist
ribution of ECT for general hospital inpatients with recurrent major d
epression and to estimate the effects of prompt ECT on the length and
cost of inpatient care. Method: Data from the 1993 Healthcare Cost and
Utilization Project were analyzed to determine the rate of ECT rue fo
r adult inpatients with a principal discharge diagnosis of major depre
ssion, recurrent. Associations between prompt initial use of ECT (in t
he first 5 hospital clays) and length and cost of inpatient care were
examined before and after control for sociodemographic, diagnostic, an
d hospital organizational characteristics. Results: An estimated 9.4%
of general hospital adult inpatients with a principal diagnosis of rec
urrent major depression received ECT in the survey year. A majority (5
9.2%) of these received their initial ECT session within the first 5 d
ays after hospital admission. In univariate analyses, the likelihood o
f receiving ECT was greater for older patients, whites, privately insu
red individuals, and patients who lived in more affluent areas. Patien
ts who received ECT tended to have relatively long and costly admissio
ns. After control for several demographic, diagnostic, and hospital or
ganizational characteristics, prompt ECT (as compared with delayed ECT
or none) was associated with significantly shorter and less costly in
patient care. Conclusions: The longer stays and higher treatment costs
associated with ECT may be a consequence of patient selection. When p
atient selection is taken into account, prompt administration of ECT i
s associated with shorter and less costly, hospital stays. Nonetheless
, economically disadvantaged patients are relatively unlikely, to rece
ive this treatment.
