In 2015, an earthquake killing 9,000 and injuring 22,000 people hit Nepal. The Tribhuvan University Teaching Hospital (TUTH), a reference tertiary hospital, was operational immediately after the earthquake. We studied the profile of earthquake victims admitted in TUTH and assessed what factors could influence hospital length of stay.
An earthquake victim dataset was created based on patient records, with information on sex, age, date of admission and discharge, diagnosis, and surgical intervention. We performed an initial descriptive overview of the earthquake victims followed by a time-to-event analysis to compare length of hospital stay in different groups, using log rank test and cox regression to calculate Hazard Ratios.
There were in total 501 admitted victims, with the peak of admissions occurring on the fifth day after the earthquake. About 89% had injury as main diagnosis, mostly in lower limbs, and 66% of all injuries were fractures. Nearly 69% of all patients underwent surgery. The median length of hospital stay was 10 days. Lower limb and trunk injuries had longer hospital stays than injuries in the head and neck (HR = 0.68, p = 0.009, and HR = 0.62 p = 0.005, respectively). Plastic surgeries had longer hospital stays than orthopaedic surgeries (HR = 0.57 p = 0.006). Having a crush injury and undergoing an amputation also increased time to discharge (HR = 0.57, p = 0.013, and HR = 0.65 p = 0.045 respectively).
Hospital stay was particularly long in this sample in comparison to other studies on earthquake victims, indirectly indicating the high burden TUTH had to bear to treat these patients. To strengthen resilience, tertiary hospitals should have preparedness plans to cope with a large influx of injured patients after a large-scale disaster, in particular for the initial days when there is limited external aid.
2015 年,一场造成 9000 人死亡、22000 人受伤的地震袭击了尼泊尔。特里布万大学教学医院(TUTH)是一家教学医院,在地震发生后立即投入运营。我们研究了在 TUTH 接受治疗的地震灾民的情况,并评估了哪些因素可能影响住院时间。
根据患者记录创建了一个地震灾民数据集,其中包括性别、年龄、入院和出院日期、诊断和手术干预信息。我们对地震灾民进行了初步描述性概述,然后进行了生存时间分析,以比较不同组的住院时间,使用对数秩检验和 Cox 回归计算危险比。
共有 501 名入院灾民,入院高峰出现在地震发生后的第 5 天。约 89%的人以损伤为主要诊断,主要发生在下肢,所有损伤中 66%为骨折。几乎 69%的患者接受了手术。住院时间中位数为 10 天。下肢和躯干损伤的住院时间长于头颈部损伤(HR = 0.68,p = 0.009 和 HR = 0.62,p = 0.005)。整形手术的住院时间长于骨科手术(HR = 0.57,p = 0.006)。挤压伤和截肢也会增加出院时间(HR = 0.57,p = 0.013 和 HR = 0.65,p = 0.045)。
与其他地震灾民研究相比,该样本的住院时间特别长,这间接表明 TUTH 在治疗这些患者方面承受了巨大的负担。为了增强弹性,三级医院应该制定应对大规模灾害后大量受伤患者涌入的准备计划,特别是在外部援助有限的最初几天。
