The effect of weather conditions on human health has been documented. However, the role of daily weather on anticipated death remains unclear. This study aimed to evaluate the relationship between daily weather conditions and death in terminally ill cancer patients.
We retrospectively searched a medical database of 935 consecutive terminally ill cancer patients who passed away in the palliative care unit from Oct 2009 to Sep 2013. We used Poisson regression to assess the relative risk (RR) of anticipated death based on various weather variables, using mean values calculated from the 10 d around the time of death.
The final study population consisted of 745 patients with a mean age of 65.9 ± 12.2 yr. The mean palliative prognostic index (PPI) score in the last week of life was 8.0 ± 3.8. After adjustment for age, sex, cancer type, and PPI score, RRs were 1.69 (95% CI, 1.17-2.46) for low temperature, 2.57 (1.77-3.77) for high diurnal temperature variation, 2.35 (1.61-3.36) for low humidity, and 1.75 (1.22-2.53) for high levels of sunlight.
Weather conditions may be a predictor of death in terminally ill cancer patients.
天气状况对人类健康的影响已有文献记载。然而，每日天气对预期死亡的作用仍不清楚。本研究旨在评估每日天气状况与晚期癌症患者死亡之间的关系。
我们回顾性检索了一个医学数据库，该数据库包含2009年10月至2013年9月在姑息治疗病房去世的935例连续晚期癌症患者。我们使用泊松回归，根据各种天气变量评估预期死亡的相对风险（RR），使用死亡时间前后10天计算的平均值。
最终研究人群包括745例患者，平均年龄为65.9±12.2岁。生命最后一周的平均姑息预后指数（PPI）评分为8.0±3.8。在调整年龄、性别、癌症类型和PPI评分后，低温的RR为1.69（95%CI，1.17-2.46），昼夜温差大的RR为2.57（1.77-3.77），低湿度的RR为2.35（1.61-3.36），高日照水平的RR为1.75（1.22-2.53）。
天气状况可能是晚期癌症患者死亡的一个预测因素。
