Rates of electroconvulsive therapy use in Edinburgh (1992-1997)

Electroconvulsive therapy in Hong Kong

Aims and Method

We conducted the first systematic territory-wide survey of electroconvulsive therapy (ECT) practice and utilisation in Hong Kong. All public ECT services were evaluated with a postal questionnaire, a visit and observations of ECT administration. All private ECT practitioners were surveyed using a postal questionnaire.

Results

Most practice areas at the public ECT services in Hong Kong complied with College guidelines. However, a few private practitioners were still using outdated ECT machines. The number of ECT courses completed in 1998 was 0.34 per 10 000 population, which was much lower than the rate of ECT use in Western countries.

Clinical Implications

We obtained basic information on ECT services in Hong Kong and on areas requiring immediate attention.

Electroconvulsive Therapy among Elderly patients: A study from Tertiary care centre in north India

OBJECTIVE

This retrospective study aimed to evaluate the effectiveness and safety of ECT among elderly patients receiving electroconvulsive therapy (ECT).

METHODS

During the study period of January 2008 to May 2017, 151 patients aged ≥60 years received ECT and they formed the study sample. Data on patients aged 19 to 59 years for the period of 3 years (2014-2016) was also extracted for comparison purposes.

RESULTS

The mean age of the elderly subjects was 65.8 years. In contrast to the young patients, elderly patients who received ECT more often had diagnosis of affective disorder, especially unipolar depression. Compared to young patients, elderly patients had higher prevalence of physical comorbidity with one third having more than one physical illness. The most common reason for use of ECT among elderly was poor response to medications (62.3%), followed by requirement of early response (49.6%). Four-fifth (80.8%) of the elderly patients showed ≥50% reduction in the symptoms with ECT. In terms of side effects, acute blood pressure changes were seen in 40.3% of patients during the ECT procedure and about half of the patients reported cognitive disturbances.

CONCLUSION

Present study suggests that ECT can be safely used among elderly patients, especially those with depressive disorders, not responding to medications.

Electroconvulsive Therapy in Women: A Retrospective Study from a Mental Health Hospital in Turkey

The aim was to evaluate the clinical profile and effectiveness of ECT in women. A retrospective chart review was carried out to identify female patients who had received ECT during the period September 2013-February 2015. Details regarding their sociodemographic, clinical, and treatment data were extracted from these records for the present study. The total number of patients, admitted to our psychiatry inpatient clinic during the survey period, was 802. During this period, 26 (3.24 %) female patients received ECT. Patients who received ECT were mostly in age group of 25-44 years (76.9 %). Twenty percent of patients were in the postpartum period. Psychotic disorders (46.1 %) was the most common diagnosis for which ECT was used, followed by bipolar affective disorder, current episode manic (19.2 %). At the end of ECT courses, 70 % of the patients showed good response with a CGI-I of 1 or 2, and 30 % showed minimal response with a CGI-I score of 3. The most common side effects were post-ECT confusion (15.4 %) and prolonged seizure (11.5 %). This rate of prolonged seizure was higher the rates reported in the literature. The bronchospasm related with remifentanil, post-ECT bradycardia, hypertensive crisis and oligohydramnios were also reported in one case each. ECT is a safe and effective treatment option in women with severe psychiatric disorders and disorders in the perinatal/postpartum period are a major area of ECT use. The female gender may be a contributing factor for the higher rates of prolonged seizure.

Neuromodulation therapies for geriatric depression

Depression is frequent in old age and its prognosis is poorer than in younger populations. The use of pharmacological treatments in geriatric depression is limited by specific pharmacodynamic age-related factors that can diminish tolerability and increase the risk of drug interactions. The possibility of modulating cerebral activity using brain stimulation techniques could result in treating geriatric depression more effectively while reducing systemic side effects and medication interactions. This may subsequently improve treatment adherence and overall prognosis in the older patient. Among clinically available neuromodulatory techniques, electroconvulsive therapy (ECT) remains the gold standard for the treatment of severe depression in the elderly. Studies have proven that ECT is more effective and has a faster onset of action than antidepressants in the treatment of severe, unipolar, geriatric depression and that older age is a predictor of rapid ECT response and remission. The application of novel and more tolerable forms of ECT for geriatric depression is currently being examined. Preliminary results suggest that right unilateral ultrabrief ECT (RUL-UB ECT) is a promising intervention, with similar efficacy to brief-pulse ECT and fewer adverse cognitive effects. Overall findings in repetitive transcranial magnetic stimulation (rTMS) suggest that it is a safe intervention in geriatric depression. Higher rTMS stimulation intensity and more treatments may need to be given in the elderly to achieve optimal results. There is no specific data on vagus nerve stimulation in the elderly. Transcranial direct current stimulation, magnetic seizure therapy and deep brain stimulation are currently experimental, and more data from geriatric samples is needed.

Contemporary use and practice of electroconvulsive therapy worldwide

To explore contemporary (from 1990) utilization and practice of electroconvulsive therapy (ECT) worldwide. Systematic search (limited to studies published 1990 and after) was undertaken in the databases Medline, Embase, PsycINFO, SveMed, and EBSCO/Cinahl. Primary data-based studies/surveys with reported ECT utilization and practice in psychiatric institutions internationally, nationally, and regionally; city were included. Two reviewers independently checked study titles and abstracts according to inclusion criteria, and extracted ECT utilization and practice data from those retrieved in full text. Seventy studies were included, seven from Australia and New Zealand, three Africa, 12 North and Latin America, 33 Europe, and 15 Asia. Worldwide ECT differences and trends were evident, average number ECTs administered per patient were eight; unmodified (without anesthesia) was used in Asia (over 90%), Africa, Latin America, Russia, Turkey, Spain. Worldwide preferred electrode placement was bilateral, except unilateral at some places (Europe and Australia/New Zealand). Although mainstream was brief-pulse wave, sine-wave devices were still used. Majority ECT treated were older women with depression in Western countries, versus younger men with schizophrenia in Asian countries. ECT under involuntary conditions (admissions), use of ambulatory-ECT, acute first line of treatment, as well as administered by other professions (geriatricians, nurses) were noted by some sites. General trends were only some institutions within the same country providing ECT, training inadequate, and guidelines not followed. Mandatory reporting and overall country ECT register data were sparse. Many patients are still treated with unmodified ECT today. Large global variation in ECT utilization, administration, and practice advocates a need for worldwide sharing of knowledge about ECT, reflection, and learning from each other's experiences.

Electroconvulsive therapy: a comparison of knowledge and attitudes of student nurses and staff mental health nurses at a psychiatric hospital in Nigeria

Electroconvulsive therapy (ECT) is effective in the treatment of some psychiatric disorders. Among other reasons, service users may refuse ECT when indicated due to myth and little or lack of knowledge about the procedure. The knowledge of and attitude towards ECT among nurses may reflect on patients and influence treatment choice. Previous studies, conducted in developed countries have explored knowledge and attitudes towards ECT among nurses, but none have been conducted in this part of the world. The following article compares the knowledge of and attitude towards ECT among student and staff mental health nurses at a psychiatric hospital in Nigeria. A cross sectional survey of 135 student nurses and staff mental health nurses showed that knowledge and attitude scores were more positive among staff mental health nurses compared with student mental health nurses. Additional years of experience correlated with better knowledge and positive attitudes among staff mental health nurses. Overall, the majority of the respondents felt that ECT was beneficial to patients, was overused and required guidelines for its practice in this country.

Knowledge of and attitude toward electroconvulsive therapy: a survey of Hungarian anesthesiology residents

AIM

To assess the knowledge of and attitudes toward electroconvulsive therapy (ECT) in Hungarian anesthesiology residents.

METHOD

A self-administered questionnaire comprising 39 questions compiled by the authors.

RESULTS

Of the 82 sophomore residents who completed the questionnaire, 29 have administered ECT. These residents were significantly more likely to consider ECT to be efficacious and less likely to be dangerous or lethal than the other residents (P = 0.017 and 0.004). Fifty-three residents (65%) rated their knowledge of ECT as "minimal," 26 (32%) as "moderate," and 1 (1.3%) as "considerable." In the case of severe depression, 49% of the "minimal" knowledge group would consent to be treated with ECT. The corresponding figure in the "moderate" knowledge group was 16% (P = 0.009).

CONCLUSIONS

Having previously administered ECT had a positive effect on the anesthesiology residents' attitudes toward ECT. Having a level of knowledge about ECT treatment that was perceived as "minimal" did not prejudice residents against it.

The rate of usage of electroconvulsive therapy in the city of Edinburgh, 1993-2005

BACKGROUND

In May 2003, the National Institute for Clinical Excellence published controversial clinical guidelines that intended to restrict the indications for the use of electroconvulsive therapy (ECT) in the United Kingdom.

OBJECTIVE

We investigated whether the guideline had affected the rate of usage of ECT in the City of Edinburgh and set this in the context of ECT usage in the City since 1993.

METHOD

We calculated the annual rate of ECT usage using a case register and contemporaneous and coterminous population data, reporting separately rates for young people (younger than 18 years), the general adult population, and older adults (aged 65 years of age and older).

RESULTS

No young person was treated after 1998. There were similar significant falls in the rates of usage in both the general adult and older age population (-60%). There was no suggestion that the fall had accelerated after May 2003.

CONCLUSIONS

No early effect of the guidance was found in the rate of ECT usage in the City of Edinburgh, but the passage of time will be required to assess any longer term effect.

Practice of electroconvulsive therapy at the research and training hospital in Turkey

OBJECTIVE

We sought to obtain an overview of electroconvulsive therapy (ECT) practice in Bakirkoy Research and Training Hospital for Psychiatric and Neurological Diseases, which is the biggest hospital for psychiatry in Turkey.

METHOD

From 1st January 2006 to 30th June 2007, a form enquiring about evaluation of ECT was filled retrospectively.

RESULTS

The total number of patients, admitted for psychiatry during the survey period was 265,283. A total of 1,531 patients (12.4% among inpatients and 0.58% in all psychiatric admissions) received 13,618 sessions (including multiple hospitalizations) of ECT from 12,341 psychiatric inpatients during the survey period. Ninety-eight patients had multiple hospitalizations. The male-to-female ratio was 1.26-1. Patients with bipolar affective disorder, current episode manic with or without psychotic symptoms received ECT most frequently (30.3%), followed by patients with schizophrenia (29.5%), severe depressive episode with or without psychotic symptoms (include bipolar affective disorder current episode severe depression) (15.2%), other non-organic psychotic disorders (14.4%), schizoaffective disorders (6.3%), mental and behavioral disorders due to psychoactive substance abuse with psychotic disorders (3.5%) and catatonic schizophrenia (0.7%). Patients who received ECT were in age group of 25-44 years (64.7%), followed by 45-64 years (17.7%), 18-24 years (15.4%), 65 years and older (1.4%), and younger than 18 years (0.8%). All patients received modified ECT. There were no ECT-related deaths during the survey.

CONCLUSION

The rate of ECT among all psychiatric inpatients during the survey period was 12.4%. The majority of patients who received ECT were diagnosed with bipolar affective disorder-current episode manic and schizophrenia. ECT training programs for psychiatry residents and specialists should be planned, and conducted systematically.

The use of electroconvulsive therapy in the elderly: a study from the psychiatric unit of a north Indian teaching hospital

OBJECTIVES

There are very little data on elderly patients receiving electroconvulsive therapy (ECT) in India. This study was a preliminary attempt at characterizing the clinical and demographic profile of elderly subjects (>or=60 years) who received ECT in the psychiatric department of a teaching hospital in north India.

METHODS

A retrospective case-note review was carried out to identify patients 60 years or older who had received ECT over an 8-year period at the Postgraduate Institute of Medical Education and Research, Chandigarh, India. Several details about their demographic and clinical profile, indications for ECT, response patterns, and adverse effects were extracted.

RESULTS

Over the 8 years, 373 patients received ECT, of which 56 (15%) were 60 years or older. Complete records were available for only 50 of these patients. The majority (96%) had depression. The index depressive episode for which ECT was used was severe in 91.6% of the subjects, and 68% had not responded to adequate psychotropic treatment before ECT. Comorbid medical illnesses were present in 66% of cases and were associated with significantly higher risk of cognitive side effects. However, side effects were usually mild; there were no serious untoward events caused by ECT. About 80% to 90% showed some response to treatment. Those who had received inadequate antidepressant treatment before ECT were significantly more likely to respond to ECT.

CONCLUSIONS

Elderly with depression constitute a substantial proportion of those receiving ECT in India. Use of ECT in this population seemed to be mainly restricted to those who were very severely ill and poorly responsive to medications. Electroconvulsive therapy seemed to be a safe and effective treatment in such situations. However, particular care may be required in the subgroup with comorbid physical problems that may be more vulnerable to cognitive adverse effects.

Are patients' attitudes towards and knowledge of electroconvulsive therapy transcultural? A multi-national pilot study

INTRODUCTION

Electroconvulsive therapy (ECT) is an effective, yet controversial treatment. Most patients receiving ECT have depression and it is likely that the majority having this treatment are older adults. However, attitudes towards ECT and knowledge of ECT in this population have never been studied in relation to the patients' cultural background.

OBJECTIVE

To compare the attitudes and knowledge of ECT among older adults depressed patients across three culturally different populations and to explore the relationship between culture, knowledge and attitudes.

METHODS

The study was conducted in one centre in each country. A semi-structured survey was used which included three sections: demographics characteristics, attitudes towards and knowledge of ECT.

RESULTS

A total of 75 patients were recruited in this study: 30 patients from England; 30 patients from Argentina; and 15 patients from Canada. There was a significant difference in knowledge about ECT across the three countries. No significant difference was found in terms of attitudes. Knowledge was poor in all three countries. The most influential factor shaping subjects' attitudes and knowledge of ECT differed for the three countries. A weak correlation was found between knowledge of and attitudes towards ECT across all patients from the three different countries.

CONCLUSION

Attitudes towards ECT are a very complex phenomenon. We could not find evidence that a particular cultural background affects attitudes towards ECT. Generalising the results of our study is restricted by the fact that this was a pilot study that suffered from limitations including small sample size and number of settings.

Electroconvulsive therapy: predictors and trends in utilization from 1976 to 2000

BACKGROUND

Use of electroconvulsive therapy (ECT) may have changed during the last decades due to advances in psychopharmacology and organizational changes of psychiatric care.

OBJECTIVES

To identify predictors for receiving ECT for the first time and to describe temporal trends in ECT utilization.

METHODS

A register-based case-control study. The sample included 2010 cases treated with ECT between 1976 and 2000 and 148,284 controls.

RESULTS

Predictors for receiving first ECT were unipolar affective disorders, long admissions, and no previous admissions. Significantly fewer patients with bipolar and schizoaffective disorders received the treatment in 2000 compared with 1976.

CONCLUSIONS

Unipolar affective disorders, long duration of admissions, and no history of previous admissions are strong predictors of receiving first ECT. Despite a decrease in available inpatient beds, the treatment is used in 5.5% of admissions, and during the last 15 years of the study period, ECT utilization has been remarkably stable.

Knowledge and attitudes toward electroconvulsive therapy among health care professionals and students

Widespread variations in electroconvulsive therapy (ECT) prescription between and within countries have led many researchers to study professionals' attitudes to the procedure. A questionnaire looking at knowledge and attitudes was administered to 593 medical and nursing students, psychiatrists and anesthetists, and theater and psychiatric nurses. Respondents were based in 2 Irish cities, Dublin and Cork. Poorer knowledge of ECT was found in the nursing group, and this included psychiatric nurses: a third overestimate ECT mortality, most did not know if it caused permanent brain damage, and only 1 psychiatric nurse (2.9%) expressed positive attitudes to its use. Nursing students had significantly lower knowledge and more negative attitudes than medical students, and exposure to the procedure of ECT failed to improve their attitudes. The strongest predictor of better knowledge and more positive ECT attitudes was membership of the medical group. There were direct associations between better knowledge and more positive attitudes in the medical group but not among the nursing group. Low ECT knowledge among psychiatric nurses has implications in obtaining patients' valid consent. Our failure to link exposure to ECT to better nursing attitudes is discussed along with other educational lessons.

[Electroconvulsive therapy at the Department of Psychiatry and Psychotherapy, University of Munich. Development during the years 1995-2002]

BACKGROUND

So far, electroconvulsive therapy (ECT) has been proven to be a reliable and the most effective somatic treatment of depression or schizophrenia. This holds especially true for disturbances, which are refractory to pharmacological treatments.

PATIENTS AND METHODS

We evaluated 4803 treatments in 445 patients. Main outcome criteria were efficacy and tolerability of treatment. Moreover, prospectively recorded neurophysiological parameters that might influence treatment outcome and treatment modalities and were assessed in a retrospective study design.

RESULTS

During the last 7 years developmental changes show an increasing call for ECT treatment. Despite not being able to satisfy all demands the number of treatments more than doubled during the time period investigated. According to the latest scientific knowledge, especially in unipolar ECT, higher stimulation energy has been used to provide better treatment efficacy. Nevertheless, this was accompanied by a lower incidence of cognitive side effects. Due to the better tolerability of the treatment and the prospective neurophysiological indices, it appears that treatment quality has improved in recent years. Overall treatment efficacy was not improved, but could be maintained on a stable high level. This is presumably due to a stronger negative selection of patients with more pharmacotherapy-refractory disturbances.

CONCLUSION

ECT still represents an important option in the treatment of therapy-resistant depression and schizophrenia despite recent progress in neuropsychopharmacology.

A national survey of electroconvulsive therapy use in the Russian Federation

A survey of electroconvulsive therapy (ECT) throughout Russia was undertaken to understand the range of ECT usage and knowledge. A survey form was distributed by mail to 1648 Russian doctors and institutions expected to deal with ECT. A total of 114 replies were received. They indicated that ECT is available to 22.4% of the country's population. In available regions, ECT is given to 1.43% of hospital admissions and 0.54 per 10,000 persons per year. ECT is used in Russian psychiatry, neurology, and addictionology. Outdated ECT instruments are used in more than one third of sites, and EEG and seizure quality are virtually never monitored. Fewer than 20% of ECTs are modified with anesthesia. There is no system or expectation for ECT training or privileging, there is no national organization that aims to advance ECT practice, and ECT research is haphazard. Nevertheless, most respondents are enthusiastic and positive about ECT, and most institutions are eager to adopt modern ECT methods.

Patterns of electroconvulsive therapy use in Spain

OBJECTIVE

To describe the utilization, geographical variations and adaptation of ECT in the Spanish context.

METHOD

A cross-sectional study, involving a questionnaire delivered to all hospitals with a Psychiatry Unit (PU) in Spain included in the National Hospitals Catalogue (N = 233). A descriptive analysis was made of the answers to the different questions, using an adequate denominator in each case: all PUs (n = 233), those units that prescribe and apply ECT (n = 174), or only those that apply the technology (n = 108).

RESULTS

All PUs completed the questionnaire. Fifty-nine units (25.3%) neither prescribed nor applied ECT, while 108 (46.4%) prescribed and applied the technology, and 66 PUs (28.3%) only prescribed ECT. Those units with training responsibilities for psychiatry residents or pregraduate students, and those with a larger number of beds, were more inclined to apply ECT. The estimated ECT applied in the preceding 12 months totaled 2435 with an annual rate per 10,000 inhabitants of 0.61, and a range per Spanish Autonomous Community of 0.28-16.59.

CONCLUSIONS

We now know a reliable rate and characteristics of the use of ECT in Spain, and the attitudes and opinion of PUs Spanish psychiatrists about it. We found a very important variability in ECT application rates among Autonomous Communities.

Electroconvulsive therapy in Hong Kong: rates of use, indications, and outcome

INTRODUCTION

There has been a concern about indiscriminate use of electroconvulsive therapy (ECT) in Asian countries. This study examined the rates of ECT use and the characteristics and outcomes of patients treated with ECT in Hong Kong.

METHOD

A central database of ECT treatments was used to calculate annual rates of ECT use from 1997 to 2002. We surveyed prospectively patients received ECT over 12 months by a standardized questionnaire.

RESULTS

The ECT utilization rates varied from 0.27 to 0.34 patients treated per 10,000 population and 1.34 to 1.88 patients treated per 100 inpatients discharged. There were differences in the pattern of ECT use among Hong Kong, the United States, and the United Kingdom. Only 15% of ECT recipients were 65 years old or older and 23% had schizophrenia as primary diagnosis for ECT. Ninety-five percent of patients who received ECT improved with the treatment as assessed by clinicians. No severe complications and deaths occurred, and 6% stopped ECT due to undesirable results.

CONCLUSION

The rate of ECT use in Hong Kong continues to be below that in the United States and the United Kingdom. Access to ECT is most limited to the elderly and private patients.

Epidemiological analysis of electroconvulsive therapy in Victoria, Australia

OBJECTIVE

To determine the population-based utilization rate of electroconvulsive therapy (ECT) in Victoria between 1998-1999, to examine the characteristics of the ECT treated group, and to identify patient factors independently associated with differential rates of ECT treatment.

METHOD

Electroconvulsive therapy is reported under statute in Victoria, Australia. Crude, age-adjusted and age-sex specific utilization rates were calculated using this statutory data for the 1998-1999 financial year and estimated mid-year populations from the Australian Bureau of Statistics. Descriptive characteristics of those treated with ECT were derived from the statutory data. Patient factors associated with an increased likelihood of ECT in the public sector were explored with logistic regression analysis, using non-ECT treated mental health patients from the Victorian Psychiatric Case Register as the reference population.

RESULTS

The crude treated-person and age-adjusted rates for the State (both public and private sectors) were 39.9 and 44.0 persons per 100 000 resident population per annum, respectively. The crude and age-adjusted administration rates were 330.3 and 362.6 ECT administrations per 100 000 resident population per annum, respectively. Age-sex specific rates varied by age and sex, with rates generally increasing with age and female sex. Overall, 62.8% of the treated group were women, 32.9% aged over 64, and 75.2% had depression. Diagnosis, age and sex each independently predicted ECT in the public sector, with diagnosis the most important factor, followed by age then sex.

CONCLUSIONS

Despite decades of use, the appropriate rate of ECT utilization is still unclear. Further research should be directed at exploring the factors, including provider variables, determining ECT treatment.

Electroconvulsive therapy for the depressed elderly

BACKGROUND

Depressive disorder is a common mental disorder in old age, with serious health consequences such as increased morbidity, disability, and mortality. The frailty of elderly may seriously hamper the efficacy and safety of pharmacotherapy in depressed elderly. Electroconvulsive therapy (ECT) in depressed elderly therefore may be an alternative to treatment with antidepressants.

OBJECTIVES

To assess the efficacy and safety of ECT (compared to simulated ECT or antidepressants) in depressed elderly.

SEARCH STRATEGY

We searched the CCDANCTR database, Medline 1966-2000, EMBase 1980-2000, Biological abstracts 1985-2000, Cinahl 1982-2000, Lilacs from 1982 onwards, Psyclit 1887-2000, Sigle 1980-2000. The reference lists of relevant papers were scanned for published reports. Hand searching of the Journal of ECT and the Journal of Geriatric Psychiatry was done. Based on the title of the publication and its abstract, non-eligible citations were excluded.

SELECTION CRITERIA

Data were independently extracted by at least two reviewers. Randomised, controlled trials on depressed elderly (> 60 years) with or without concomitant with conditions like cerebrovascular disease, dementia of the Alzheimer's type, vascular dementia or Parkinson's disease were included.

DATA COLLECTION AND ANALYSIS

Data were independently extracted by at least two reviewers. For continuous data weighted mean differences (WMD) between groups were calculated.

MAIN RESULTS

Randomised evidence is sparse. Only three trials could be included, one on the efficacy of real ECT versus simulated ECT (O'Leary et al 1994), one on the efficacy of unilateral versus bilateral ECT (Fraser 1980) and the other comparing the efficacy of ECT once a week with ECT three times weekly (Kellner 1992). All had major methodological shortcomings; data were mostly lacking essential information to perform a quantitative analysis. Although the O'Leary study concluded that real ECT was superior over simulated ECT, these conclusions need to be interpreted cautiously. Only results from the second trial (unilateral versus bilateral ECT) could be analysed, not convincingly showing efficacy of unilateral ECT over bilateral ECT, WMD 6.06 (CI -5.20,17.32). Randomised evidence on the efficacy and safety of ECT in depressed elderly with concomitant dementia, cerebrovascular disorders or Parkinson's disease is completely lacking. Possible side-effects could not be adequately examined because the lack of randomised evidence and the methodological shortcomings.

REVIEWER'S CONCLUSIONS

None of the objectives of this review could be adequately tested because of the lack of firm, randomised evidence. Given the specific problems in the treatment of depressed elderly, it is of importance to conduct a well designed randomised controlled trial in which the efficacy of ECT is compared to one or more antidepressants.

Barriers to the use of electroconvulsive therapy in the elderly: a European survey

A postal survey was carried out to determine the clinical and legal guidelines governing the use of electroconvulsive therapy (ECT) in the countries of the wider Europe. Respondents from 23 of the 33 countries returned completed questionnaires. Considerable variation was found in the availability of ECT, the frequency of its use and associated legal procedures. However, there was a broad consensus with regard to the clinical indications. Access to the treatment was most frequently limited by financial or other resource constraints, political or legal restrictions.

Variation in rates of electroconvulsive therapy use among consultant teams in Edinburgh (1993-1996)

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.
