Influenza: Critique of the contemporary challenges for pandemic planning, prevention, control, and treatment in emergency health services.

The 2009 H1N1 influenza pandemic was a major challenge to health services around the world. Previous experiences with Severe Acute Respiratory Syndrome (SARS) and Avian Influenza A (H5N1) prompted initiation of formal pandemic planning. Essential and desirable features of pandemic plans include preparation for surveillance, investigation of cases, treatment modalities, prevention of community spread, maintenance of essential services, research and evaluation, and implementation, testing and revision of the plan. The experience of 2009 H1N1 influenza pandemic for emergency departments and their staff was problematic. The pace of the pandemic, coupled with untested pandemic plans, presented a unique range of challenges. In this paper, the contemporary challenges with respect to pandemic influenza prevention, control, and treatment are examined. The lessons learned are critical to our response to future pandemics, which are inevitable.

Demand for hospital emergency departments: a conceptual understanding.

BACKGROUND: Emergency departments (EDs) are critical to the management of acute illness and injury, and the provision of health system access. However, EDs have become increasingly congested due to increased demand, increased complexity of care and blocked access to ongoing care (access block). Congestion has clinical and organisational implications. This paper aims to describe the factors that appear to influence demand for ED services, and their interrelationships as the basis for further research into the role of private hospital EDs. DATA SOURCES: Multiple databases (PubMed, ProQuest, Academic Search Elite and Science Direct) and relevant journals were searched using terms related to EDs and emergency health needs. Literature pertaining to emergency department utilisation worldwide was identified, and articles selected for further examination on the basis of their relevance and significance to ED demand. RESULTS: Factors influencing ED demand can be categorized into those describing the health needs of the patients, those predisposing a patient to seeking help, and those relating to policy factors such as provision of services and insurance status. This paper describes the factors influencing ED presentations, and proposes a novel conceptual map of their interrelationship. CONCLUSION: This review has explored the factors contributing to the growing demand for ED care, the influence these factors have on ED demand, and their interrelationships depicted in the conceptual model.
