| 17 | Impact of the earthquake during COVID-19 lockdown on fracture admission at a tertiary trauma centre in Croatia显示文摘Purpose:To determine the impact of an earthquake during COVID-19 lockdown on fracture admission at a tertiary trauma centre in Croatia.Methods:A case-control study was performed at the tertiary trauma centre registry.Two different periods were studied.The case group included a period during COVID-19 lockdown right after the earthquakes until the end of the confinement period in Croatia.And the control group corresponded to the equivalent period in 2019.We identified all consecutive patients who were admitted due to urgent care requirements for the musculoskeletal trauma.Patient's demographic data and admitting diagnoses were assessed.Data were analyzed by statistical procedures using the program MedCalc statistical software version 16.4.3.Results:We identified 178 emergency admissions due to musculoskeletal trauma.During the COVID-19 lockdown and post-earthquake period,there was a drastic reduction in total admissions(359 vs.662;p<0.0001)with an increased proportion of trauma admissions within the emergency admissions(34.9%vs.26.5%;p=0.02926,Z=-2.1825).Furthermore,in the case group there was a significant increase in hospital admissions due to ankle/foot trauma(11 vs.2,p 0.0126)and a trend towards a decrease in the admissions due to tibia fractures(5 vs.12,p=0.0896),however without statistical significance.Also,an increased proportion of women within the group of femoral fractures in both case group(81.6%vs.52.6%,p=0.00194,Z=3.1033)and the control group(82.3%vs.60.5%,p=0.0232,Z=2.2742)was observed.In both analyzed periods,the osteoporotic hip fracture was the most common independent admitting diagnosis.Conclusion:It is crucial to understand how natural disasters like earthquakes influence the pattern of trauma admissions during a coexisting pandemic.Accordingly,healthcare systems have to be prepared for an increased influx of certain pathology,like foot and ankle trauma. | Dino Bobovec Tomislav Zigman Daniel RajacicTin Ehrenfreund Andreja Prtoric Ivan Dobric | 2022 | Chinese Journal of Traumatology2022，25，3： | 0 |
