A comparison of heatwave response plans from Australia, Canada, the UK, and the USA Benjamin Okwuofu-Thomas Department of Environment and Geography Outline Background: Heatwave mortality impacts in aged care facilities (ACFs) Aim Methods Results Conclusions Background Heatwaves result in significant excess mortality, particularly amongst the elderly in ACFs, and pose formidable health care challenges. Garssen et al. (2005); Stafoggia et al. (2006) In Germany for example, in August 2003, over 400 excess heatwave mortalities were recorded in residents of ACFs. Klenk et al.

Background Climate change results in increases in heatwave frequency, duration, spatial extent and intensity, making heatwave impacts on human health an increasing risk into the future. IPCC, AR5, WGI, SPM (2013) Heatwave response plans are government documents detailing preparation for and response to heatwaves, and are a key adaptation measure. Victorian Government (2010) Aim This presentation examines 23 heatwave response plans with particular focus on specific responses aimed at residents of aged care facilities. Methods Heatwave response plans were sourced via the internet and direct from the national, state/ provincial, and municipal health departments. A total of 23 heatwave response plans dated from December 2004- January 2013 were obtained. 15 heatwave response plans from Australia. 3 heatwave response plans from Canada. 3 heatwave response plans from the UK. 2 heatwave response plans from the USA. All countries are developed and high income nations; and experiencing demographic transition of the ageing populations. Methods This presentation focusses on three aspects of the analysis: Heat stress prevention strategies; Inclusion of Aged Care Facilities; Heatwave response communication. Results Frequency of heat stress prevention strategies from the 23 heatwave response plans.

Cold bath or body wash No fans on humidity Rest breaks Results Only three of the 23 plans included specific heatwave response guidance for ACFs. These were: Victoria’s Residential Aged Care Services Heatwave Ready Resource; Canada’s Extreme Heat Events Guidelines: Technical Guide For Health Care Workers; and UK’s Supporting Vulnerable People Before and During A Heatwave: Advice for Care Home Managers and Staff. Results Frequency of communication strategies in the 23 heatwave response plans. Conclusions Inconsistency in plans and projected increases in severity and frequency of heatwaves in coming decades underline the need for governments to implement effective guidelines that include specific provisions for ACF.
