An armed assailant in our hospital: Are we prepared?

While armed assailant attacks are rare in the hospital setting, they pose a potential risk to healthcare staff, patients, visitors and the infrastructure. Singapore hospitals have well-developed disaster plans to respond to a mass casualty incident occurring outside the hospital. However, lack of an armed assailant incident response plan can significantly reduce the hospital's ability to appropriately respond to such an incident. The authors describe various strategies that can be adopted in the development of an armed assailant incident response plan. Regular staff training will increase staff resilience and capability to respond to a potential threat in the future. The aim of this article is to highlight the need for the emergency preparedness units of all hospitals to work together with various stakeholders to develop an armed assailant incident response plan. This will be of great benefit for keeping healthcare facilities safe, both for staff as well as for the community.

Advanced Cardiac Life Support: 2016 Singapore Guidelines

The main areas of emphasis in the Advanced Cardiac Life Support (ACLS) guidelines are: early recognition of cardiac arrest and call for help; good-quality chest compressions; early defibrillation when applicable; early administration of drugs; appropriate airway management ensuring normoventilation; and delivery of appropriate post-resuscitation care to enhance survival. Of note, it is important to monitor the quality of the various care procedures. The resuscitation team needs to reduce unnecessary interruptions to chest compressions in order to maintain adequate coronary perfusion pressure during the ACLS drill. In addition, the team needs to continually look out for reversible causes of the cardiac arrest.

Post-resuscitation care

Following return of spontaneous circulation (ROSC) after cardiac arrest, the challenge is to institute measures that ensure a higher likelihood of neurologically intact survival. Regardless of the cause of collapse, multiple organ systems may be affected secondary to post-cardiac arrest syndrome. Interventions required for post-ROSC care are bundled into a care regimen: prompt identification and treatment of the cause of cardiac arrest; and treatment of electrolyte abnormalities. It is also essential to establish definitive airway management to maintain normocapnic ventilation, prevent hyperoxia, and optimise haemodynamic management via judicious intravenous fluids and vasoactive drugs. Targeted temperature management after ROSC confers neuroprotection and leads to improved neurological outcomes. Glycaemic control of blood glucose levels at 6-10 mmol/L, adequate seizure management and measures to optimise neurological functions should be integrated into the care bundle. The interventions outlined can potentially lead to more patients being discharged from hospital alive with good neurological function.

Potential impact of early physiotherapy in the emergency department for non-traumatic neck and back pain / 世界急诊医学杂志（英文）

BACKGROUND:Musculoskeletal complaints, especially non-traumatic neck and back pain, are routinely encountered in the emergency department (ED) and lead to ED overcrowding, a burgeoning wait time for physiotherapy and outpatient orthopedic reviews. The study aimed to evaluate the impact of early physiotherapy evaluation and treatment (EPET) vs. standard care (SC) on clinical outcomes for patients presenting to the ED with non-traumatic neck and back pain. METHODS:A retrospective observational study of 125 patients who presented to the ED with non-traumatic neck and back pain with/without peripheral symptoms from July 2010 to February 2011. Neck Disability Index (NDI), Modified Oswestry Low Back Pain Disability Questionnaire (MODI) and 11-point Numeric Pain Rating Scale were used as outcome measures and compared between groups at a mean of 34 days from their initial ED visit. RESULTS:We identified a total of 125 patients. EPET group comprised 62 patients (mean age, 45 years; men, 63％) and SC group comprised 63 patients (mean age, 45 years; men, 43％). The EPET and SC groups received physiotherapy at a median of 4 and 34 days respectively from their first ED visit. EPET patients had significantly lower levels of disability (9.0％ vs. 33.4％, Welch t-test, P<0.001) and pain (median value, 1 vs. 4 points, Mann-Whitney U-test, P<0.001) compared with SC patients. CONCLUSION:Early access to physiotherapy in ED was associated with reduced pain and disability levels. EPET protocol can potentially decrease the demand on outpatient orthopedic services, thereby freeing up available resources to treat patients who are more likely to benefit from it.
