Abstract

The full effects of meteorological variables on mortality have not yet been elucidated. This study’s aim was to investigate whether 30-day in-hospital mortality in emergency hospital admissions for non-respiratory diseases were sensitive to the effects of humidity and ambient temperature on the day of admission. We studied all emergency medical admissions to St. James’s Hospital, Dublin, during 2002-2018 (n=113,807) and investigated temperature and humidity on day of admission. We employed multivariable logistic regression to identify temperature and humidity mortality predictors, adjusting for underlying comorbidities. Lower temperatures on day of admission predicted higher 30-day in-hospital mortality (adjusted OR: 1.12, 95% CI: 1.06-1.17), but lower humidity levels did not (adjusted OR: 0.97, 95% CI: 0.91-1.03). There was no interaction between meteorological variables and comorbidities on mortality. In conclusion, temperature may be a more significant predictor of in-hospital mortality than humidity for non-respiratory patients.
