Significant increases in NEC mortality and EHAs were observed during heatwaves in Brisbane where people are well accustomed to hot summer weather. The most vulnerable were the elderly and people with cardiovascular, renal or diabetic disease.

IntroductionPharmacists are uniquely placed in the community to be of assistance to disaster-affected patients. However, the roles undertaken by pharmacists in disasters are identified based on their own experiences and networks. There is currently no definition or acknowledgment of pharmacists’ roles in disasters.ObjectiveTo acquire consensus from an expert panel of key opinion leaders within the field of disaster health on pharmacists’ roles in disasters throughout the four disaster phases—prevention, preparedness, response, and recovery.MethodsA Delphi study consisting of three rounds of online surveys was utilised. Twenty-four key opinion leaders were contacted, with 15 completing all three rounds. The 15 expert panellists were presented with 46 roles identified in the literature and asked to rank their opinions on a 5-point Likert scale. This study used an international, all-hazard, and multijurisdictional approach. Consensus was benchmarked at 80% and any role which did not reach consensus was re-queried in the subsequent round. The third round provided the results of the Delphi study and sought commentary on the acceptance or rejection of the roles.ResultsOf the 46 roles provided to the expert panel, 43 roles were accepted as roles pharmacists are capable of undertaking in a disaster. There were five roles for the prevention phase, nine for the preparedness phase, 21 for the response phase, and eight for the recovery phase. The experts were asked to prioritise the top five roles for each of the disaster phases. The three roles which did not make consensus were deemed to be specialised roles for disaster pharmacists and not generalisable to the broader pharmacy profession.ConclusionThis study identifies pharmacists’ roles in disasters which have been accepted by the international disaster health community. The international key opinion leaders recommended that pharmacists could be undertaking 43 roles in a disaster, however, this is dependent on individual jurisdiction considerations. Pharmacy professional associations need to advocate to policymakers for legislative support and to ensure pharmacists are equipped with the training and education required to undertake these roles within specific jurisdictions.

Various biometeorological indices and temperature measures have been used to assess heat-related health risks. Composite indices are expected to assess human comfort more accurately than do temperature measures alone. The performances of several common biometeorological indices and temperature measures in evaluating the heat-related mortality in Brisbane, Australia-a city with a subtropical climate-were compared. Daily counts of deaths from organic causes [International Statistical Classification of Diseases and Related Health Problems, 9th Revision, (ICD9) codes 001-799 and ICD, 10th Revision, (ICD10) codes A00-R99] during the period from 1 January 1996 to 30 November 2004 were used. Several composite biometeorological indices were considered, such as apparent temperature, relative strain index, Thom discomfort index, the humidex, and wetbulb globe temperature. Hot days were defined as those days falling into the 95th percentile of each thermal stress indicator. Case-crossover analysis was applied to estimate the relationship between exposure to heat and mortality. The performances of various biometeorological indices and temperature measures were compared using the jackknife resampling method. The results show that more deaths were likely to occur on hot days than on other (i.e., control) days regardless of the temperature measure or biometeorological index that is considered. The magnitude of the odds ratios varied with temperature indicators, between 1.08 [95% confidence interval (CI): 1.02-1.14] and 1.41 (95% CI: 1.22-1.64) after adjusting for air pollutants (particulate matter with aerodynamic diameter less than 10 mm and ozone). Average temperature performed similarly to the composite indices, but minimum and maximum temperatures performed relatively poorer. Thus, average temperature may be suitable for the development of weather-health warning systems if the findings presented herein are confirmed in different locations.

This growth in demand exceeds general population growth, and the variability between states both in utilization rates and overall trends defies immediate explanation. The growth in demand for ED services is a partial contributor to the crowding being experienced in EDs across Australia. There is a need for more detailed study, including qualitative analysis of patient motivations in order to identify the factors driving this growth in demand.

Although this pilot programme had support from all levels of management as well as from the service providers, it did not translate into actual referrals. Several explanations are provided for these preliminary findings.
