Audit of electroconvulsive treatment in two national health service regions.

The practice of ECT has been surveyed by visits to all 35 NHS hospitals and five private clinics where it is used in the North East Thames and East Anglian Regions, and observation of ECT administration in 29 NHS and two private clinics. Since 1981 there has been much improvement in the physical conditions in which ECT is given and in anaesthetic practice. Nursing is good or excellent in a majority. About half the clinics have the most effective Ectron constant-current series 5 apparatus; the rest have older models with which 'missed' fits and undertreatment are frequent. Stimulus-dosing is usually by habit rather than rational strategy, and routine instrument settings differ fourfold between clinics. Most hospitals have nominated consultants in charge of ECT, but few of these are closely involved and little has changed in the unsatisfactory training and supervision of those who give the treatment. The use of ECT has fallen by 55% in North East Thames Region since 1979, but has risen by 20% in the East Anglian Region. There are up to 12-fold differences in usage between districts.
