ECT for treatment-resistant schizophrenia: a response from the far East to the UK. NICE report.

BACKGROUND: There is controversy about the proper place of electroconvulsive therapy (ECT) in the management of the schizophrenic patient, and the important issues related to theory and practice remain to be resolved, especially in the context of medication-resistant schizophrenia. METHOD: We briefly summarize existing research in the field. We next use a narrative method to describe in a single article the large body of research from Thailand that, during the past decade, has systematically studied issues related to the use of ECT in medication-resistant schizophrenia. We integrate the findings of the Thai efforts with the results of other research and consider the theoretical and practical importance of the reviewed work. RESULTS: The ECT treatment data validate a BRPS cutoff of 25 as a definition of recovery in patients with treatment-refractory schizophrenia, and a cutoff of 37 as a definition of subsequent relapse or suitability for entry into a treatment protocol. A 3-week post-ECT stabilization period identifies patients who maintain improvement and who can be legitimately considered to have sustained response to ECT. Clinical characteristics of such responders and symptoms responsive to ECT are described. Higher stimulus dose hastens response to ECT but does not improve responsiveness. Continuation ECT (C-ECT) combined with maintenance-neuroleptic medication is associated with better treatment outcome than either treatment alone. The combined treatment also improves quality of life and functioning in the long-term. CONCLUSIONS: These findings convey several useful thoughts for research into and the practice of ECT for schizophrenia.

Survey of the practice of electroconvulsive therapy in teaching hospitals in India.

OBJECTIVES: We sought to obtain an overview of electroconvulsive therapy (ECT) practice in teaching hospitals in India. METHOD: From September 1, 2001, to August 31, 2002, a 29-item questionnaire enquiring about ECT practice during the past year was sent to 188 teaching institutions and psychiatric hospitals. RESULTS: Seventy-four institutions (39.4%) completed the questionnaire. ECT was available in 66 institutions. A total of 19,632 patients received 114,111 instances of ECT from 316 psychiatrists, of which 13,891 patients (70.8%) received 89,475 treatments (78.4%) from 128 psychiatrists in the psychiatric hospitals. The male-to-female ratio was 1.56 to 1. Brief-pulse device was used in 39 institutions. EEG monitoring was used routinely in only 8 institutions. Bilateral ECT was used in almost all institutions. Patients with schizophrenia received ECT most frequently (36.5%), followed by patients with major depression (33.5%), mania (17.9%), catatonia (6.2%), and dysthymia (2.8%). Patients who received ECT were in age group of 45-64 years (43.9%), followed by 25-44 years (34.5%), 65 years and older (14.7%), 18-24 years (5.6%), and younger than 18 years (1.4%). A total of 10,234 patients (52%) received unmodified ECT 52,450 treatments (46%) at 33 institutions. There was one case of ECT-related death during a survey. Continuation ECT was performed in 29 institutions and maintenance ECT in 17. CONCLUSIONS: More than 70% of ECT administrations in India were performed in the psychiatric hospitals. Approximately half of ECT use was unmodified ECT. The majority of patients who received ECT were diagnosed with schizophrenia and major depression. ECT training programs for psychiatry residents were acceptable.

ECT practice in Japan.

OBJECTIVES: We sought to determine the characteristics of electroconvulsive therapy (ECT) practice in Japan. Only by knowing practice patterns can standards of care be successfully developed and implemented. METHODS: From September 1, 2001, to August 31, 2003, a questionnaire was sent to 248 institutions. RESULTS: A total of 100 institutions (40.3%) completed the questionnaire. ECT was available in 83 institutions. A total of 1,210 patients received 11,146 ECTs from 895 psychiatrists. Brief-pulse device was used in 21 institutions. EEG monitoring was used routinely in 15 institutions. Bilateral ECT was always used. Patients who received ECT were diagnosed schizophrenia (48.9%), major depression (37.4%), catatonia (6.8%), mania (4.4%), and dysthymia (0.8%). The majority of patients who received ECT were in the age group 45-64 years (40.4%) and 65 years and older (39.3%). A total of 670 patients received a total of 6364 unmodified ECT at 60 institutions. There were no ECT-related deaths during the survey. CONCLUSION: ECT use in Japan is low. More than half of ECTs instituted were unmodified. The majority of patients who received ECT were diagnosed with schizophrenia and major depression.

Electroconvulsive therapy practice in Thailand.

OBJECTIVES: To obtain an overview of electroconvulsive therapy (ECT) practice in Thailand. METHODS: Questionnaires were sent to all institutions providing psychiatric care; data were collected from September 1, 2001, to August 31, 2002. RESULTS: Fifty-three responses were received from 67 institutions (79.1%). ECT is available in 26 hospitals. Approximately 6,914 patients received 51,565 ECT treatments, of which, 6,469 patients (93.56%) received 48,240 treatments (93.55%) in the psychiatric hospitals. The ECT utilization rate was 11.15 patients treated per 100,000. Twelve institutions used MECTA (Spectrum or SR1) or Thymatron DGx. Bilateral ECT was used exclusively in all institutions. In 2 medical schools, all patients received double ECT throughout their treatment courses. Unmodified ECT was always used in nine psychiatric hospitals and five general hospitals, and occasionally used in 2 university hospitals comprising 94.2% of all ECT usage. Patients with schizophrenia most frequently received ECT (74%), followed by mania (8%) and major depression (7%). The nurse alone administered ECT in four psychiatric hospitals. Although the death rate was estimated at 0.08%, there was no ECT-related death during the survey period. Continuation ECT was performed in 11 and maintenance ECT in 6 institutions. Five institutions had acceptable training programs for psychiatry residents but none had training syllabus, 2 institutions had teaching schedule for medical students. CONCLUSIONS: ECT use in Thailand is high. Nearly all ECTs (93.6%) were performed in the psychiatric hospital and 94.2% of all treatments were unmodified ECT. Lacking of proper training in ECT is evident.

Acute and maintenance ECT with flupenthixol in refractory schizophrenia: sustained improvements in psychopathology, quality of life, and social outcomes.

OBJECTIVE: To determine the effects of ECT combined with antipsychotic medication therapy on psychopathology, quality of life, and social functioning in patients with refractory schizophrenia. METHOD: An open acute (Phase I) and maintenance (Phase II) study of the combination of ECT and flupenthixol in the treatment of 46 schizophrenic patients who were nonresponsive to antipsychotic medication from at least two different classes. Scales used: the Brief Psychiatric Rating Scale (BPRS), the Quality of Life Scale (QLS), Social and Occupational Functioning Assessment Scale (SOFAS), Global Assessment of Functioning (GAF), and Mini-Mental State Exam (MMSE). The duration of Phase II was 1 year. RESULTS: In Phase I, there were marked reductions in the BPRS scores, and substantial increases in the QLS, SOFAS, GAF, and MMSE scores. During Phase II, the BPRS negative symptoms worsened but remained improved from baseline. Changes in other outcome measures were negligible. CONCLUSION: ECT and MECT combined with flupenthixol were effective in improving psychopathology in patients refractory to antipsychotic medication alone. Ratings of psychopathology, quality of life, and social functioning all improved in Phase I and were generally sustained during Phase II in patients who had remitted.
