Összefoglaló szövege

Introduction: Out-of-hospital cardiac arrests (OHCA) represent a critical public health challenge, with poor survival heavily influenced by various factors.
Aims: Our objective was to investigate the relationship between environmental factors, such as extreme temperatures, solar radiation, humidity, and the frequency of OHCA in Hungary from November 1, 2018, to April 25, 2022.
Methods: We conducted an analysis of 50,589 OHCA cases using data from the Hungarian National Ambulance Service and meteorological records. For analysis and visualization Poisson regression models were applied. Extreme temperatures were categorized by percentiles, and a generalized linear model was used to analyze the impact of weather conditions on OHCA incidence.
Results: OHCA incidents increased significantly during extreme cold (below 0°C) and extreme heat (above 25°C). Low relative humidity correlated with fewer, while high humidity led to more cases (p < 0.001). OHCA frequency increased notably on days with weather front compared to non-frontal days (p < 0.001). No significant correlation was found between precipitation and OHCA cases. Higher solar radiation was linked to fewer OHCA cases, whereas lower solar radiation correlated with increased case number (p < 0.001).
Conclusion: We identified significant associations between extreme temperatures, rapid temperature changes, and the incidence of OHCA. Higher solar radiation and temperatures were linked to fewer OHCA cases, whereas lower radiation and temperatures, along with high humidity, increased the incidence. These findings underscore the intricate relationship between environmental factors and OHCA, emphasizing the necessity for targeted public health strategies to mitigate the risk during extreme weather conditions.
