确定和评估极端高温事件对新南威尔士州（NSW）五个地区人口的健康影响。这些数据为制定旨在减少气候变化影响导致的疾病负担的政策和方案举措提供了必要的证据。采用仅病例方法分析了悉尼东部和西部、伊拉瓦拉、戈斯福德-怀昂和纽卡斯尔的1，497，655例急诊入院病例。每个地区每日最低和最高温度的分布被用来定义极端高温（千分之九十九）。我们调查了急诊入院的主要原因对极端高温的敏感性。我们还研究了基础疾病的存在作为极端高温下急诊入院的风险修正因素。主要原因：在极热的日子里，由于热相关损伤、脱水和其他液体、电解质和酸碱平衡紊乱而急诊入院的风险比其他原因入院的风险增加更多。基本条件：那些有潜在的精神和行为障碍、神经和循环系统疾病，特别是心脏病、呼吸系统疾病，特别是哮喘和慢性阻塞性肺病、肿瘤和肾脏疾病，特别是肾衰竭的人，更容易受到极端高温事件的影响。我们确定了几个主要的诊断和急诊入院的基本条件，特别是对极端高温事件敏感。这方面的知识可以直接有助于建立健康计划，有效地针对那些由于极端高温而紧急入院的相对风险较高的人。
To determine and characterise the health impacts of extreme heat events on the population in five regions of New South Wales (NSW). Such data provide evidence necessary for the development of policy and programme initiatives designed to reduce the burden of disease due to the impact of climate change.A case-only approach was used to analyse 1,497,655 emergency hospital admissions in Sydney East and West, Illawarra, Gosford-Wyong and Newcastle. The distribution of daily minimum and maximum temperatures in each region was used to define extreme heat (a parts per thousand yen99th percentile). We investigated the susceptibility of the main causes of emergency hospital admission to extreme heat. We also examined the presence of underlying conditions as a risk modifier of emergency hospital admission on extreme heat. Logistic regression model was used to estimate the effect modifications.Main causes: On days of extreme heat, the risk of emergency hospital admission due to heat-related injuries, dehydration and other disorders of fluid, electrolyte and acid-base balance increased more than the risk of admission from other causes. Underlying conditions: Those with underlying mental and behavioural disorders, diseases of nervous and circulatory system, especially cardiac, diseases of respiratory system, especially asthma and chronic obstructive pulmonary disease, neoplasms and renal disease, especially renal failure, were more susceptible to an extreme heat event.In this study, we identified several main diagnoses and underlying conditions for emergency hospital admission that are particularly susceptible to extreme heat events. This knowledge can contribute directly to establishing health programmes that would effectively target those with higher relative risk of emergency hospital admission due to extreme heat.
