Despite being a preventable cause of death, drowning is a global public health threat. Australia records an average of 288 unintentional drowning deaths per year; an estimated annual economic burden of $1.24 billion AUD ($2017). On average, a further 712 hospitalisations occur due to non-fatal drowning annually. The Australian state of New South Wales (NSW) is the most populous and accounts for 34% of the average fatal drowning burden. This study aims to explore the demographics and outcome of patients who are admitted to hospitals for drowning in NSW and also investigates prediction of patients' outcome based on accessible data.
This protocol describes a retrospective, cross-sectional data linkage study across secondary data sources for any person (adult or paediatric) who was transferred by NSW Ambulance services and/or admitted to a NSW hospital for fatal or non-fatal drowning between 1/1/2010 and 31/12/2019. The NSW Admitted Patient Data Collection will provide data on admitted patients' characteristics and provided care in NSW hospitals. In order to map patients' pathways of care, data will be linked with NSW Ambulance Data Collection and the NSW Emergency Department Data Collection. Finally patient's mortality will be assessed via linkage with NSW Mortality data, which is made up of the NSW Register of Births, Deaths and Marriages and a Cause of Death Unit Record File. Regression analyses will be used to identify predicting values of independent variables with study outcomes.
This study has been approved by the NSW Population & Health Services Research Ethics Committee. Results will be disseminated through peer-reviewed publications, mass media releases and at academic conferences. The study will provide outcome data for drowning patients across NSW and study results will provide data to deliver evidence-informed recommendations for improving patient care, including updating relevant guidelines.
尽管溺水是一种可预防的死亡原因，但它仍是全球公共卫生威胁。澳大利亚每年平均有288例意外溺水死亡；估计每年经济负担为12.4亿澳元（2017年）。平均而言，每年还有712人因非致命溺水住院治疗。澳大利亚新南威尔士州（NSW）人口最多，占溺水致死平均负担的34%。本研究旨在探讨新南威尔士州因溺水入院患者的人口统计学特征和预后情况，并根据可获取的数据调查患者预后的预测因素。
本方案描述了一项回顾性横断面数据关联研究，该研究基于二级数据源，针对2010年1月1日至2019年12月31日期间由新南威尔士州救护服务部门转运和/或因致命或非致命溺水入住新南威尔士州医院的任何人（成人或儿童）。新南威尔士州住院患者数据收集将提供新南威尔士州医院住院患者的特征和所接受治疗的数据。为了绘制患者的护理路径，数据将与新南威尔士州救护数据收集和新南威尔士州急诊科数据收集相关联。最后，通过与新南威尔士州死亡率数据（由新南威尔士州出生、死亡和婚姻登记册以及死因单位记录文件组成）关联来评估患者的死亡率。回归分析将用于确定自变量与研究结果的预测值。
本研究已获得新南威尔士州人口与健康服务研究伦理委员会的批准。研究结果将通过同行评审出版物、大众媒体发布以及学术会议进行传播。该研究将提供新南威尔士州溺水患者的预后数据，研究结果将为改善患者护理提供循证建议，包括更新相关指南。
