The team adjusted pharmacotherapy for the next two weeks before referring her to our ECT service. Unfortunately, the patient completed suicide 2 days before her scheduled ECT in our service. This tragic vignette underscores the importance of not just having an ECT service but having one that can respond in a timely fashion to patient needs. While 5 of the 7 ECT services 15 in Singapore were still operational at the time of this writing, the other 2 have shut down due to lack of anaesthesia manpower while others now require case by case approval for ECT by the operating theatres. There are other inherent challenges of an ECT service in a COVID-19 environment. ECT requires general anaesthesia which involves close contact with patient oral and airway secretions and actively encouraging the patient to cough in the recovery room after ECT. Each patient contact with the team can last for several hours in a small, confined environment with recirculated air and repeated 10 to 20 times over a period of weeks to months. Patients from a wide geographical region 16 and are often kept in close contact in small rooms for several hours before and after ECT. Patients receiving ECT tend to be older 14 and have a high chance of having comorbid medical conditions like hypertension or diabetes 17 all of which increases their mortality if infected with COVID-19 7 . Further, patients receiving ECT often have poorer hygiene 18 , live in crowded wards or housing 19 and are hence less able to observe the which increases the risk of both ECT staff being infected by a large pool of high risk patients and infected ECT staff infecting other units when they rotate out of their ECT duties. Common challenges facing ECT and other medical services in an COVID-19 environment include potential shortages of personal protective equipment (PPE) like N-95 masks, face masks, protective eye goggles, gowns and hospital grade disinfectants like 70% ethanol wipes 21 . An even greater challenge is the lack of manpower to have a full backup team or allow staff to rest sufficiently. Despite these numerous challenges it is possible to maintain a safe, high volume and high quality ECT service during a COVID-19 pandemic. COVID-19 was not Singapore"s first brush with a deadly coronavirus. In 2003 Singapore was struck by SARS (Severe Acute Respiratory Syndrome) caused by a novel coronavirus resulting in 238 cases and 33 deaths, including healthcare workers 8 . We learnt the importance of screening, contact tracing and isolation of cases and contacts to effectively manage a novel coronavirus 22 outbreak. We also enhanced our institutional and national capability to deal with pandemics by establishing a national centre for infectious diseases (NCID) to provide infectious disease outbreak management and public health preparedness to strengthen Singapore's capabilities in infectious disease prevention and management. NCID became fully operational in 2018 23 . During SARS the ECT service in the Institute of Mental Health (IMH) was not prepared and had to shut down due to the need to protect staff and patients. At the time ECT nursing manpower Copyright © 2020 Wolters Kluwer Health, Inc.

Singapore first heightened its awareness of the impending COVID-19 pandemic on 2 nd Jan 2020 24 , informing all healthcare providers to be vigilant about fever or acute respiratory cases with a travel history to Wuhan. Singapore diagnosed its first COVID-19 case on 23 rd Jan 2020 with local transmission reported by 7 th Feb 2020. The Disease Outbreak Response System Condition (DORSCON) alert was raised to Orange on 7 th Feb 2020, indicating that the disease is severe and spreads easily from person to person but was not widely spreading and being contained 25 (See Table 1 for details of DORSCON). Singapore is a small nation state at the tip of the Malaysian archipelago. It has a population of admitted or assessed to lack capacity (as defined in the Mental Capacity Act 28 as the ability of the patient to understand the information, weigh up the information, remember the information, or communicate the decision) can be prescribed ECT by their treating psychiatrist. Singapore adopted a Whole-of-Government (WOG) approach with a multi-ministry task force coordinating all COVID-19 related activity. Specific measures that related to healthcare included travel restrictions placed on healthcare staff travelling to high risk areas, home quarantine for staff returning from high risk areas and restriction of practice locations to a single or limited number Copyright © 2020 Wolters Kluwer Health, Inc.

All healthcare staff were to take and document their temperature twice a day to monitor for symptoms of COVID-19 and mask fitting exercises (for N95 masks) for all clinical staff were completed in Jan 2020. All leave for healthcare staff was cancelled to facilitate business continuity plans (BCP) of having backup teams so that if a team member was infected with COVID-19, the alternative team would come to replace them while the exposed team would be put on quarantine 30 . Staff who could not get refunds for travel cancellations were reimbursed by IMH. Singapore with 1900 inpatient beds and about 40,000 outpatients and treats about 80% of the national load of psychiatric patients. In IMH, ECT is prescribed primarily for schizophrenia (47%) with schizoaffective disorder (20.3%), depression (20.4%) and mania (6.8%) being the other major indications 15 . In 2015 IMH moved from a one-size-fits-all approach (age based dosing with bitemporal electrode placement) to an individualized seizure threshold titration based approach 31,32 with a range of electrode placements (Bitemporal, Bifrontal, Right unilateral) and pulse parameters (Brief or Ultrabrief pulsewidth) using the CARE network system to collect ECT data 33 . Treatment results at IMH for ECT have been comparable with international norms [34] [35] [36] . ECT was conducted over 3.5 days a week with an average of 15 treatments per half day session.

There was a projected need to redeploy staff to man 24-hour screening centres and bolster the rosters of certain wards like the medical ward, emergency clinic, forensic ward and satellite clinics. This was to ensure enough manpower for wards to be fully independent if there was a need to stop any cross-ward movement of staff which was commonly done to optimize manpower usage. In addition, the ECT service mixed staff and patients from almost all the wards in IMH daily, creating a high-risk area for cross infection of patients and staff. However, it was recognized early in DOTF discussions that ECT was the only treatment for severe life-threatening conditions like catatonia and was a treatment commonly used to enhance patient recovery for earlier discharge. Stopping the ECT service would result in a delay of discharge for many inpatients at a time when it was even more critical to return patients to their home expeditiously rather than keep then housed with other patients and increase their risk of infection. Hence the ECT service was identified as an essential service and our BCP was The ECT team worked closely with our infection control team to determine the risks posed to staff and patients by the COVID-19 virus with our current operations. After a review of the risks Copyright © 2020 Wolters Kluwer Health, Inc. Unauthorized reproduction of this article is prohibited. ECT and in the recovery room) required full PPE (N95 masks, protective eye wear, full surgical gown, gloves) while non-clinical ECT staff interacting with patients would require a 3 ply facemask and gloves at all times when interacting with patients and that PPE would be changed between each batch of patients. It was also decided to enhance ECT room disinfection with 70% ethanol wipes between patients to minimize the chance of cross infection between patients. IMH had a small stockpile of PPE but quickly increased its holding stock after the infection control measures (i.e. full PPE) were confirmed and our projected usage of PPE would be several orders of magnitude higher than pre-COVID-19. Increased disinfectant hand rub and 70% ethanol wipes were also ordered in bulk. Decontaminating the ECT room pre-COVID-19 was done by estate management after a half-day session. The COVID-19 situation necessitated more cleaning and disinfection services. We arranged with our estates management team to have a cleaner on site during ECT operational hours to respond expeditiously to ECT room decontamination between batches of patients and ECT staff helped with cleaning their own area of work with 70% ethanol. We switched to single use Mapleson C circuits for anaesthesia for each batch of patients with disposable bite blocks, oral airways and HEPA (high efficiency particulate air) filters for each patient.

Pre-COVID-19 ECT operations emphasized efficiency and hence patients often spent a significant amount of time waiting pre/post ECT in the ECT room. There was routine mixing of patients from different wards and inpatient with outpatients. Staff were also routinely rotated with a pool of 10 different ECT practitioners, approximately 30 public and private sector anaesthetists and 30 nursing staff rotating to fill 12 staff positions (1 ECT practitioner, 1 Anaesthetist, 10 nursing staff) on any given day. The status quo operations resulted in an unacceptably high level of patient and staff interaction with correspondingly high risk of exposure to COVID-19. A decision was made to restrict the pool of staff down to just 2 ECT practitioners, 2 anaesthetists and 11 nursing staff and reduce the number of staff required at any time to 11 (down from 12). We were able to reduce the number of staff required by enlisting the ward and outpatient staff to assist with ECT patient transportation. One of the ECT nursing staff would have a new role of receiving ECT patients and conducting COVID-19 risk screening and temperature taking before letting the patient into the ECT room. This nursing staff also ensured that a maximum of 1 visitor equipped with a face mask could accompany the patient. This was on top of IMH measures of restricting all access to a single entrance operated 24/7 by a dedicated screening team using the current suspect COVID-19 case definition and temperature screening. These changes required a concerted effort from nursing and human resources to adjust contracts and staff allocation. We were also fortunate to have recently trained an advance practice nurse (APN) to be an ECT practitioner 37 which allowed for a backup ECT practitioner as 8 of the original 10 ECT practitioners were Copyright © 2020 Wolters Kluwer Health, Inc.

The alternate ECT practitioner and anaesthetist did not meet their counterparts to prevent cross team infection and 2 reserve nurses were similarly deployed outside the ECT room as alternative nursing staff. The alternative team allowed the primary team to take short local leave of up to 3 days at a stretch for staff rest and recuperation. Copyright © 2020 Wolters Kluwer Health, Inc. Unauthorized reproduction of this article is prohibited. The need to decontaminate the ECT room between batches of patients meant that we had to spread out the ECT for wards with only a few patients over different days to minimize decontamination time. This way we were able to decrease the decontamination sessions (each lasting almost 30 min) from 5-6 to 3-4 a day. Figure 1 below illustrates the large decrease in ECT capacity in the first week of DORSCON Orange but with the measures described above capacity slowly increased over the next 5 weeks. We separately increased the number of ECT sessions from 7 to 8 half-day sessions to maintain ECT capacity with plans to increase to a full 10 half-day session a week. A daily huddle was conducted before and after ECT sessions to iron out teething issues and help bolster staff morale by addressing their concern and incorporating their suggestions. ECT staff did not routinely use full PPE (see Image 2) so dedicated refresher training sessions were held by infection control staff for the ECT team on how to apply and remove PPE safely and revise disinfection protocols for equipment. It was insufficient to just teach the proper usage of PPE as its usage was cumbersome and initial staff adherence was poor. Twice daily audits of ECT staff adherence was conducted to ensure proper usage of PPE and infection control procedures. Despite our best efforts our ECT capacity would have decreased from about 115 treatments a week to only 80 to 90 treatments a week despite increasing the number of half-day sessions from Copyright © 2020 Wolters Kluwer Health, Inc.

While planning to increase the number of ECT sessions it became evident that we also need to enlist the help of our colleagues in reducing ECT demand to prevent a situation where we would have to use "wartime triage" to decide on who would be able to access lifesaving ECT akin to the situation in Italy with respirators for COVID-19 patients 39 . We started communicating with referring psychiatrists about the decreased ECT treatment capacity which would necessitate a decrease of ECT frequency from thrice a week to twice a week for most cases and had individual case discussions with clinicians about decreasing the frequency of outpatient maintenance ECT. Lastly, we used our routine pre-ECT assessments clinics to assess the severity, urgency and likelihood of response to ECT vis-à-vis the availability of ECT treatment capacity to prioritize patients for ECT. The system was tested in the third week of DORSCON Orange when a confirmed COVID-19 contact was diagnosed in an inpatient ward where there were 10 patients receiving ECT. The contact was immediately quarantined in our medical ward isolation bed and the ward "buttoned up" (i.e. no patient movement in or out of the ward). A discussion between the ECT service, infection control and NCID was conducted to assess the risk of infection to staff and patients. After a review and audit of our infection control procedures and assessing the need for ECT for the 10 patients on the ward, the collective decision was that our current infection control protocols was enough to allow for continued ECT for other patients in the ward. This was in large part due to the full PPE for staff, physical separation of patients by ward location and decontamination of the ECT room between different batches of patients from separate wards. Copyright © 2020 Wolters Kluwer Health, Inc. Unauthorized reproduction of this article is prohibited. Fortunately, the contact eventually tested negative for COVID-19 but the system was robust enough to continue providing timely ECT despite the infection risk. The WHO Director general recommended a comprehensive strategy of preparation, detection, transmission reduction and innovation to combat COVID-19 3 . The descriptions of the IMH ECT service adaptations for COVID-19 covered the first 3 points but continuous innovation was implicit in all 3 steps. As of this writing the IMH ECT service has been operating in DORCON Orange for 6 weeks and each week brings new revisions to our operations to improve safety or increase capacity. We are increasingly looking into the sustainability of our operations with the realization that the COVID-19 situation was not going to last for a few short months as initially hoped, but possibly a year or more 10 . Staff morale would be key in sustaining the fight against COVID-19 and was bolstered by strong leadership communicating a clear patient-oriented mission that staff could rally behind, balanced with staff safety and welfare. It is a time of great fear and uncertainty, but as Winston Churchill famously said, we will never surrender in this fight against an invisible and invidious enemy; our patients and families need us to win this war.
