The results of the new study will be presented today at the annual meeting of the Radiological Society of North America (RSNA).\n                                                <\/p>\n<p>                                                                                &#8220;Trauma accounts for a large portion of hospital admissions, and since polytrauma is particularly time-consuming and unpredictable, we wanted to investigate the association between weather fluctuations and the number of polytrauma CTs performed at our hospital,&#8221; said study co-author Martin Segeroth, M.D., a radiology resident in the Department of Radiology and Nuclear Medicine at the University of Basel in Switzerland.<\/p>\n<p>Patients who suffer polytrauma sustain multiple traumatic injuries at once and typically require a whole-body CT that includes at least the chest, abdomen and pelvis. The exam requires a radiologist to provide an im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>te reading and possible follow-up imaging and interpretation.<\/p>\n<p>The researchers&#8217; dataset included 4,613 polytrauma CT scans performed in the Emergency Department of the University of Basel between 2011 and 2020. The median age of patients was 57 years, and 66% were male.<\/p>\n<p>The research team collected daily weather data, including average temperature, total cloud cover, wind speed, sunshine duration and precipitation.<\/p>\n<p>Statistical analysis of the weather and imaging data revealed that hotter weather with more sunshine and UV light, less wind and fewer clouds was associated with a higher volume of polytrauma CTs. Colder, windier, cloudier days with less sunshine and less UV light correlated with fewer polytrauma CTs. More polytrauma CTs were performed at the hospital in the summer months (April through September) compared to the winter months (October through March).<\/p>\n<p>&#8220;Many hospital admission rates, most notably those for respiratory and cardiovascular disease, are linked to weather variations,&#8221; Segeroth said.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/sunny-with-a-chance-of-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/sunny-with-a-chance-of-1.jpg\" data-sub-html=\"Visual presentation of normalized number of polytrauma CTs and: (A) temperature with a positive association.
