On January 12, 2010, a 7.0 magnitude earthquake devastated metropolitan Port au Prince and surrounding areas and resulted in widespread injury, mortality and displacement. This study aimed to estimate the injury rate among the affected population and the resulting demand of emergency medical care in the aftermath of the earthquake.
In January 2011, a cross-sectional stratified cluster (60×20 household) survey of the earthquake-affected population in metropolitan Port au Prince was conducted to assess their well-being, unmet needs and perceptions of humanitarian assistance one year post-earthquake. Mixed effects simple and multiple logistic regressions were used to measure the total unadjusted and adjusted odds of injury.
A total of 261 injuries were reported in the pre-earthquake population of 6489 individuals with reported injury status. The overall earthquake injury rate was estimated at 40.2 injuries/1000 (CI: 35.6-45.3). Individual characteristics such as age, gender, and education status were not significantly associated with risk of injury. Elevated injury rates were observed among households residing in camps at 46.7/1000 (CI: 39.7-54.5) as compared to those in neighbourhoods where the injury rate was 33.7/1000 (CI: 27.8-40.5) (p=0.018). Extrapolation of the survey injury rate to the affected population yields an estimated 124,577 earthquake injuries (range 110,048-140,033) which is substantially lower than the 300,000 reported injuries.
Estimates of the injury burden in disasters in lower- and middle-income countries is essential for disaster preparedness and response planning in future natural disasters. Given the difficulties in reporting injuries in emergencies, including both challenges of aggregating information and lack of standardized definitions and inclusion/exclusion criteria for injuries that are not severe, ascertaining the injury burden of disasters will be a persistent challenge.
2010 年 1 月 12 日，海地首都太子港及其周边地区发生 7.0 级地震，造成广泛伤亡、死亡和流离失所。本研究旨在估计受灾人群的受伤率以及地震后的紧急医疗需求。
2011 年 1 月，对太子港地震受灾人群进行了一项横断面分层聚类（60×20 户家庭）调查，以评估他们在地震一年后的福祉、未满足的需求和对人道主义援助的看法。使用混合效应简单和多项逻辑回归来衡量未经调整和调整后的总受伤几率。
在 6489 名有报告受伤状况的人群中，报告了 261 例受伤。总体地震受伤率估计为 40.2 例/1000（置信区间：35.6-45.3）。个体特征，如年龄、性别和教育程度与受伤风险无显著相关性。居住在营地的家庭的受伤率较高，为 46.7/1000（置信区间：39.7-54.5），而居住在社区的家庭的受伤率为 33.7/1000（置信区间：27.8-40.5）（p=0.018）。将调查受伤率外推到受灾人群中，估计有 124577 例地震受伤（范围 110048-140033），远低于报告的 300000 例受伤。
对中低收入国家灾害中的受伤负担进行估计，对于未来自然灾害的备灾和应对规划至关重要。鉴于在紧急情况下报告受伤存在困难，包括汇总信息的困难以及缺乏标准化的定义和严重程度以下的受伤的纳入/排除标准，确定灾害的受伤负担将是一个持续的挑战。
