Pupillary Response as Assessment of Effective Seizure Induction by Electroconvulsive Therapy
Published on: April 11, 2019
Background:
Critics of electroconvulsive therapy (ECT) have expressed concern about variations in ECT use among consultant teams within the same hospital. The aim was to establish whether or not there was a significant variation in rates of ECT use among consultant teams in the same hospital when in-patient workload was taken into account.
Methods:
A computerised database was used to calculate annual and aggregate rates of ECT use by consultant team, expressed as the number of individual in-patients treated per 100 in-patients discharged between 1993 and 1996.
Results:
The variation in aggregate rates of ECT use varied approximately 18-fold among the 11 general adult psychiatric teams (P<0.001), and twofold among the three sector old-age psychiatric teams (P<0.05).
Conclusions:
Substantial variation in the rates of ECT use was confirmed, but only among general adult psychiatric teams.
Limitations:
The extent to which findings from one teaching hospital can be generalised was unknown. Possible explanations of the variations were not assessed.
