Kuala Lumpur train collision during the COVID-19 pandemic

Abstract

Background Two city trains collided in an underground tunnel on 24 May 2021 at the height of COVID-19 pandemic near the Petronas Towers, Kuala Lumpur, Malaysia, immediately after the evening rush hours. We aim to evaluate the management of this mass casualty incident highlighting the lessons learned to be used in preparedness for similar incidents that may occur in other major cities worldwide. Methods Information regarding incident site and hospital management response were analysed. Data on demography, triaging, injuries and hospital management of patients were collected according to a designed protocol. Challenges, difficulties and their solutions were reported. Results The train's emergency response team (ERT) has shut down train movements towards the incident site. Red zone (in the tunnel), yellow zone (the station platform) and green zone (outside the station entrance) were established. The fire and rescue team arrived and assisted the ERT in the red zone. Incident command system was established at the site. Medical base station was established at the yellow zone. Two hundred and fourteen passengers were in the trains. Sixty-four of them were injured. They had a median (range) ISS of 2 (1–43), and all were sent to Hospital Kuala Lumpur (HKL). Six (9.4%) patients were clinically triaged as red (critical), 19 (29.7%) as yellow (semi-critical) and 39 (60.9%) as green (non-critical). HKL's disaster plan was activated. All patients underwent temperature and epidemiology link assessment. Seven (10.9%) patients were admitted to the hospital (3 to the ICU, 3 to the ward and 1 to a private hospital as requested by the patient), while the rest 56 (87.5%) were discharged home. Six (9.4%) needed surgery. The COVID-19 tests were conducted on seven patients (10.9%) and were negative. There were no deaths. Conclusions The mass casualty incident was handled properly because of a clear standard operating procedure, smooth coordination between multi-agencies and the hospitals, presence of a 'binary' system for 'COVID-risk' and 'non-COVID-risk' areas, and the modifications of the existing disaster plan. Preparedness for MCIs is essential during pandemics.

Monkeypox: A current emergency global health threat

“…Management of a recent major train collision in Kuala Lumpur, Malaysia during the peak of the COVID-19 pandemic has highlighted this important point. [ 64 ] Although the two disasters were of different nature (trauma and infectious disease), occurring at the same time needed certain considerations. It is important to be flexible and innovative to address both at the same time.…”

“…This should include a strong command system which will organize all hospital activities during the pandemic, identify the required resources, define priorities of the needed supplies, and coordinate actions to be taken. [ 64 65 ] Health care providers should protect themselves by wearing N95 masks, gloves, gown, and eye protectors, when examining or treating confirmed or suspected MPXV patients. These precautions are very effective in preventing the transmission of the virus.…”

“…Public health recommendations were reminded to the public repeatedly such as adequate mask usage, encouraging regular hand washing, effective coughing and sneezing techniques, and other personal hygiene and sanitation practices. 5 Numerous data and information gaps have been detected due to the nature of the novel coronavirus. [6][7][8] The most important questions were how to prevent, diagnose, and respond to the spread of the disease acceptably and effectively and how cases should be handled in community and medical health settings.…”
