Introduction

After its introduction in 1938 in Italy, the use of electroconvulsive therapy (ECT) expanded during the 1940s [1]. It is the oldest method of somatic treatment, long before chlorpromazine and lithium came. After the initial surge, the use of ECT declined with advent of psychotropics, however its use picked up momentum after 1980s for its utility in drug resistant cases [2,3].

Although originally used in schizophrenia, presently ECT is considered an effective and relatively safe treatment of severe psychiatric states, including major depression, mania, and schizophrenia [4,5]. In certain situations, for example, treatment-resistant schizophrenia, ECT augmentation is still the treatment of choice [6]. Overall the use in affective disorders has been the main indication of ECT [7].

ECT is being prescribed worldwide, around one million patients being treated annually [8]. ECT standards and practice vary markedly between different countries, within same country, and even within individual centers [9]. Several studies have examined the practice of ECT in Asian countries where psychotic and affective disorders predominate the list and a wide variation in usage and clinical profile [10]. Chung while reporting ECT use in Hong Kong in a 12-month period observed that major depressive disorder was the most common diagnostic indication (40%), followed by schizophrenia (23%), bipolar disorder, manic or mixed episode (19%), bipolar disorder, depressed episode (10%), and schizoaffective disorder (9%) [11].

Kashmir Valley has a special geopolitical place and the data reveals that in the conflict situation over the past two decades, there has been a phenomenal increase in psychiatric morbidity in Kashmir and so the need for psychiatric services [12]. The application of ECT has been one the main pivots of psychiatric services in Kashmir, but no study to date has systematically attempted to obtain data on all ECT treatments within such a large population base. With this overview in mind this study was conducted in the lone Institute of the Valley with ECT facility available. A methodological limitation of the study is that it is retrospective and reviewed data that was available at the institute.

Method

The study was carried at Department of Psychiatry, Government Medical College Srinagar, Jammu and Kashmir, India which is a major psychiatric facility. The hospital has a well maintained ECT case sheets which contain the basic soicodemographic and clinical details of the patients attending for ECT. The data of patients attending ECT from January 2011 to December 2013 was collected, reviewed and analysed systematically. Diagnosis was the principle diagnosis for which ECT was given.

Results

The ECT facility at Department of Psychiatry, Government Medical College Srinagar, Jammu and Kashmir, India is the only such facility catering to the needs of people of whole Kashmir Valley, Ladakh and parts of Jammu Division Comprising a population of 6,907,623 [13] spread over approximately 22,236 square kilometres [14].

Modified bilateral ECT was administered twice a week and the patients are recruited both from IPD and OPD. A formal informed consent was taken for every ECT treatment. A resident Psychiatrist administered the ECT with the aid of an anaesthesiologist and an assistant. It was supervised by a consultant psychiatrist. An indigenously manufactured brief-pulse, constant energy machine (Medicaid Systems, Chandigarh, India) was used with a constant current of 1 m A and a pulse width of one millisecond. Frequency and duration of current was adjusted as per the dose needed. Motor seizure was regularly monitored by the cuff method. Propofol and succinyl-choline was routinely used along with other pre medications, thiopental was used as a second line agent. ECT was administered in a separate ECT suite with a three bedded recovery room. In the ECT suite there was a monitor for vitals with an electrocardiogram, an anaesthetic apparatus, a defibrillator, oxygen equipment, pulse oximeter, suction apparatus, defibrillator, and the necessary emergency drugs.

From January 2011 to December 2013 there were 90 patients who received 691 ECT treatments (Table 1). The average number of treatments per patient was 7.7 (standard deviation 2.12) with the shortest course of one treatment and the longest one of twenty-six treatments. Crude ECT usage rate expressed as the number of patients treated per 100,000 resident population per annum was 0.44. Majority 64.5% (58) were males and a sizable number of patients were from rural background 58.8% (53). Majority 72.2% (65) represented the adult age group of less than 40 years. Two patients were pregnant, both in the second trimester.12 patients received more than one treatment course with one of them receiving four treatment courses during these three years.

The diagnosis of these patients varied from major depression to mutism of schizophrenia at one end and neuropsychiatric manifestations of organic syndromes like systemic lupus erythematosis at the other end. Major depression was the single individual diagnosis of these patients, 27.8% (25).The average number of treatments per patient of major depression was 8.08.

Schizophrenia and Obsessive Compulsive Disorder were represented equally, 14.5% (13). Two patients of catatonic schizophrenia also received ECT and the rest of them were mainly paranoid schizophrenia. The average number of treatments per patient of OCD was 12.2, which was highest among all. 18 Bipolar Affective Disorder (BPAD) patients received ECT, 11 of them in mania and 7 in depressive phase of the illness. The average number of treatments per patient of BPAD was 5.2, which was the lowest. 16 patients received ECT for suicidality in the form of a recent suicidal attempt, suicidal plans/wishes at the time of assessment or were the team believed that the patient had a risk of suicide. This group included the patients of intended suicide regardless of the primary diagnosis. Majority of them had depressive illness and a number of them had psychotic illnesses.

‘Others’ (5.5% N=5) included patients of SLE, Parkinsonism, non-catatonic mutism of schizophrenia and schizoaffective disorders. Overall the reasons for ECT included non-response to pharmacotherapy, the severity and urgency (suicidality) of symptoms, distress to await drug response, patient preference and previous response.

The most common side effect was memory problems, which was found in 46.7% (42) patients. Headache and muscle pain was reported by 34.5% (31) and 18.9% (17) patients respectively. Post-ictal delirium was reported in two patients. No mortality was reported.

Majority of these patients were on a combination of drugs (78.89%). Benzodiazepines were most frequent prescribed drugs, common being clonazepam, lorazepam and alprazolam. Antidepressants included a fairly equal proportion of older and newer ones. Divalprox sodium was the frequently prescribed mood-stabiliser (17 patients) while as lithium was being prescribed in 10 patients. Other mood-stabilisers included carbazepine, lamotriagine and a combination of these. Antipsychotics including both typical and atypical were prescribed in 34 patients (37.78%).

The outcome of the ECT courses could not be ascertained fully as the records didn’t reveal any specific rating scale applied except for Clinical Global Impressions (CGI) scale in case of 63 patients only. Out of this limited information it was observed that 36 out of 63 patients reported a major improvement at the end of course (read as Much Improved on CGI-I) while as 10 of them reported no improvement (No Change on CGI-I) and 8 of them read as Very Much Improved. Number of patients reporting being Minimally Improved and Minimally Worse on CGI-I was 9 and 2 respectively. Overall 44 of 63(69.84%) showed an improvement. Maximum improvement was seen in suicidality, bipolar affective disorders, major depression and the least improvement was reported in OCD and schizophrenia.

Discussion

This is the first retrospective audit study from Northern India. Since this study is carried at the only and the major Psychiatric facility in Kashmir Valley, it is likely to give a clear view of ECT practices and utilization in this part of world. Since it is more like an audit and not a simple survey, the results depicted are very near to the actual practice of ECT, although the retrospective nature of the study is a shortcoming.

Our finding of ECT usage rate of 0.44 per 10000 population in Kashmir Valley is far less than the worldwide varying rates of 1.1 in Poland to 51 in United States [15,16]. In Asia, ECT usage rate has been only reported from Thailand (11.5) and Hong Kong ranging (2.7-3.4) [11,17]. Although the ECT utilization rate has not been reported from rest of India for comparisons at the local level, our rate is still far less than the global trend. Explanations to this could be complex, ranging from the availability of services, professional beliefs concerning the efficacy and safety of ECT, the socio-cultural factors and the stigma [18]. Whatever may be the reason our finding presses for the need to develop such facilities, educate the people, and update the clinicians and to expand the already available services.

Average number of treatments was hovering around the worldwide average of 8 treatments per patient. The Asian average has been 6-8 treatments per patient [7]. The closeness of values is a rough predictor of adherence to global norms/guidelines by our institute. However the wide range of ECT treatments per patient depicts the variable clinical profile of the patients. A good number of patients had more than one treatment course, which on one hand depicts the cycling nature of illnesses and the limited time-bound effect of ECT but on the other hand points towards the belief of these patients on this neurostimulative technique. However this cannot be concluded without further research.

The predominance of males has been as per the global and the national trend [19,20]. More than seventy percent of our patients were aged less than forty years which is different than western literature [8,21]. However similar pattern of age distribution has been reported in Thailand.17 The lower age distribution may represent the different symptom profile of Asian patients. Moreover the preferences of the psychiatrist and anaesthesiologist to selectively exclude elderly with medical comorbities and the maintained family structure in this part of the world leading to less severe illnesses in elderly could be contributing for their decreased representation for ECT.

Affective disorder (unipolar/bipolar depression) was the main diagnoses in our study as has been seen in Australia and New Zealand [21-23]. Affective disorders have been also the main diagnoses in USA (72–92%) [16,24]. Main diagnostic indication in Asia overall has been schizophrenia [17]. However, in Saudi Arabia [25], Pakistan [26], and Hong Kong [27], depressive illness was the main indication (over 60%), similar to our observation. The lesser use of ECT in schizophrenia (14.5%) could be due to doubts about the co-operativity of the patient and lesser patient preference for ECT. Moreover the continuous use and free availability of long-acting antipsychotics for last four years in this institution could be reason for decreased need for ECT in schizophrenics. The encouraging results in affective disorders further might have led to deputation of more such patients for ECT.

The percentage of OCD (14.5%) was much more than what has been studied so far which delineates the overall prolonged course and refractoriness of this disorder to other therapies [10]. The over-representation of OCD in our study points towards a relatively better outcome on ECT which opens a new horizon of research in the management of OCD. Although the response was not as promising as in affective disorders but was definitely promising for further work in this area.

Sucidality being an emergency to both the clinician and the care-givers represented significantly, depicting the rapid action and acceptability of ECT in such situations. Most of these suicidal patients showed a rapid and significant change on CGI-I, depicting the underlying affective illness as observed and reported in literature [28].

The response to ECT by majority of patients is consistent, as the chunk of patients belonged to affective disorders and as would be expected from the evidence elsewhere in literature, patients with affective disorders were the major responders [29,30]. Decreased response by schizophrenics is presumed to be the effect of deputation of more severe and resistant cases for ECT. The response and percentage of OCD patients is a new horizon as already discussed. However the response to ECT can’t be contested upon as a single subjective scale was administered that too by different persons. Further there was no information about the patients who completed the treatment course and who didn’t. Further the follow-up post ECT was not available to give us a better idea of overall efficacy.

The rate of adverse event being lesser than in literature, although seems promising but the trend of underreporting can‘t be denied [31]. Also there was no use of rating scales which precisely document the expected complications.

It was heartening to find that only bilateral ECT was used, fitting well with the convincing evidence of bilateral ECT being efficacious than unilateral. Further the administration of two ECTs per week is in unison with the recommendations of Royal College of Psychiatrists [32]. Further the team approach, coordination and uniformity of protocol, well equipped and well monitored ECT suite, and use of approved brief-pulse machine was a promising sign. However administration of ECT in a bigger ECT room with application of rating scales would be warranted in future.

Conclusion

It is satisfactory to note that ECT services in this part of India are in line with global trends, although more such facilities need to come up. The very limited availability of this effective treatment modality be addressed by the state health authorities. Overall affective disorders form the chunk of patients receiving ECT, and OCD has a significant representation. The non-response to drugs and urgency/severity of symptoms are the main reasons of ECT. Moreover prospective research is needed to evaluate the efficacy of ECT in different disorders.
