Contrasting patterns of mortality and hospital admissions during hot weather and heat waves in Greater London, UK

摘要: Background: Epidemiological research has shown that mortality increases during hot weather and heat waves, but little is known about the effect on non-fatal outcomes in UK. Aims Methods: The effects of waves emergency hospital admissions were investigated Greater London, UK, for a range causes age groups. Time series analyses conducted daily admissions, 1 April 1994 to 31 March 2000, using autoregressive Poisson models with adjustment long term trend, season, day week, public holidays, Christmas period, influenza, relative humidity, air pollution (ozone, PM 10 ), overdispersion. modelled average mean temperature over index previous two days. Results: There was no clear evidence relation between total high ambient temperatures, although there related respiratory renal disease, children under 5, disease 75+ group. During wave 29 July 3 August 1995, showed small non-significant increase: 2.6% (95% CI −2.2 7.6), while rose by 10.8% 2.8 19.3) after adjusting time varying confounders. Conclusions: impact not paralleled similar magnitude which supports hypothesis many deaths occur people before they come medical attention. This evident implications health, merits further enquiry.
