Injuries are a serious public health concern in Wales resulting in around 1102 deaths, 41,817 hospital admissions, 444,274 ED attendances, 59,177 Disability Adjusted Life Years (DALYs – a summary measure for the number of years lost due to poor health, disability or early death) and costs to the Welsh economy of around £1.8 billion each year.

A key resource to support the reduction of injuries in Wales is the All Wales Injury Surveillance System (AWISS).  AWISS is a population-based, multisource injury surveillance system, which collects and analyses data on injury risk factors, severity, outcomes and costs, to empower injury prevention practitioners and policy makers, to make evidence based informed decisions.  For example, AWISS data can be used to identify groups at high risk of injury and to support the planning and evaluation of injury related interventions and policies.

Up until 2008, AWISS was solely based on ED data from only major ED departments.  However the development of the ‘Secure Anonymised Information Linkage’ (SAIL) databank at Swansea University in which the AWISS system operates, opened up opportunities to include additional datasets in AWISS, including: inpatient and outpatient data from the Patient Episode Database for Wales, data from over 80% of general practices in Wales, mortality data from the Office of National Statistics, data on the treatment of burns from the Welsh Burns Centre, and demographic data from the Welsh Demographic Service.


AWISS is funded by Public Health Wales, a NHS organisation providing professionally independent public health advice and services to protect and improve the health and wellbeing of the population of Wales. Although this website was funded by Public Health Wales, the views expressed are entirely those of the AWISS and should not be assumed to be the same as those of Public Health Wales.
