The aim of the study was to measure the effect of colder winters compared to warmer winters on hospital admission rates in Suffolk County.
The setting of this study was Suffolk County in eastern England. The period of the study was financial years 2003/04-2012/13. The study was an analytic ecological study. Analysis involved calculation of rate ratios of hospital admission rates in colder winters compared to warmer winters, in all persons and the elderly.
The main finding of the study was that all rate ratios for hospital admission rates in colder winters compared to warmer winters were significantly raised with effects of 2-5%. Rate ratios for all admissions in persons of all ages and persons aged 65 years and over were, respectively, 1.02 (99% confidence interval (CI): 1.01, 1.03; P < 0.001) and 1.02 (99% CI: 1.01, 1.04; P < 0.001). Rate ratios for emergency admissions in persons of all ages and persons aged 65 years and over were, respectively, 1.05 (99% CI: 1.03, 1.06; P < 0.001) and 1.04 (99% CI: 1.01, 1.06; P < 0.001).
In Suffolk County, hospital admission rates are significantly raised in colder winters compared to warmer winters. This evidence may be useful in planning hospital services.
本研究旨在测量与温暖冬季相比，寒冷冬季对萨福克郡住院率的影响。
本研究的地点为英格兰东部的萨福克郡。研究期间为 2003/04 财年至 2012/13 财年。本研究为分析性生态学研究。分析包括计算寒冷冬季与温暖冬季相比，所有人群和老年人的住院率的比率比。
本研究的主要发现是，与温暖冬季相比，寒冷冬季的所有住院率比率均显著升高，增幅为 2-5%。所有年龄段人群和 65 岁及以上人群的所有入院率比率分别为 1.02（99%置信区间（CI）：1.01，1.03；P < 0.001）和 1.02（99% CI：1.01，1.04；P < 0.001）。所有年龄段人群和 65 岁及以上人群的急诊入院率比率分别为 1.05（99% CI：1.03，1.06；P < 0.001）和 1.04（99% CI：1.01，1.06；P < 0.001）。
在萨福克郡，与温暖冬季相比，寒冷冬季的住院率显著升高。这一证据可能有助于规划医院服务。
