Contrasting patterns of hospital admissions and mortality during heat waves: Are deaths from circulatory disease a real excess or an artifact?

摘要: In old subjects exposed to extreme high temperature during a heat wave, studies have consistently reported an excess of death from cardio- or cerebro-vascular disease. By contrast, dehydration, stroke, acute renal insufficiency, and respiratory disease were the main causes hospital admission in two carried out elderly short spells hot weather. The circulatory by mortality studies, but not morbidity could be explained hypothesis that deaths occur rapidly isolated people before they reach hospital. Since contrasting patterns waves also due chance (random variation over time space spectrum diseases induced heat), bias (poor quality diagnosis on certificate other artifacts), it should confirmed concurrent study morbidity. Many heat-related may preventable with adequate warning appropriate response emergencies, preventive efforts are complicated interval elapse between temperatures death. Therefore, prevention programs must based around rapid identification high-risk conditions persons. effectiveness intervention measures formally evaluated. If fatal health outcomes exposure death, might useful indicator evaluating watch/warning system.
