  • + Notes

    Perpetrator type is identified using the fifth character subdivisions in the first external cause code (see codes tab for more detail). The total includes a small number of records for assault not requiring a five character external cause code. The records without the fifth character are code Y87.1 - sequelae of assault.

    Only NSW residents are included. Rehabilitation episodes are excluded. Figures are based on where a person resides, rather than where they are treated. Hospital separations were classified using ICD-10-AM. Rates were age-adjusted using the Australian population as at 30 June 2001.

    Records relating to acute hospital transfer and statistical discharge were excluded.

    Patients treated solely within the emergency department are excluded from this indicator report due to a policy change (PD2017_015). Please note that a minority of patients being managed in short stay areas of emergency departments are still included. Further information is found in a paper in the HealthStatsPLUS Methods tab on this website.

    Numbers for recent years include an estimate of the small number of hospitalisations of NSW residents in interstate public hospitals, data for which were unavailable at the time of production. Further details can be found in the Methods tab in the following HealthStats NSW indicator:

    LL/UL 95%CI = lower and upper limits of the 95% confidence interval for the point estimate.

  • + Commentary

    Hospitalisations for interpersonal violence include injuries from assaults inflicted by another person with intent to injure by any means, including bodily force (such as punching, pushing or submersion), weapons, objects or substances. Both perpetrators (ie those with intent to injure) and victims (ie those who are the target of the assault or are uninvolved bystanders) may be hospitalised for injuries related to interpersonal violence.

    It is important to note that these hospitalisations include only those patients sustaining injuries severe enough to be admitted to hospital. These figures do not include those patients treated in hospital emergency departments and discharged without admission.

      This indicator uses the first external cause code.

      All records are included for NSW residents only. Rehabilitation records are excluded, unless otherwise stated. 

      Codes refer to the type of assault: firearm discharge, knife, blunt object etc

      Perpetrator not available 0= spouse or domestic partner; 1= parent; 2= other family member; 3= carer; 4= acquaintance or friend; 5= official authorities; 6= person unknown to the victim; 7= multiple persons unknown to the victim; 8= other specified person; 9= unspecified person.

      Fifth character subdivisions used with the codes X85-Y09. For example: X95.20 is Assault by shotgun discharge by spouse or domestic partner; X95.40 is Assault by large calibre rifle discharge by spouse or domestic partner;Y00.00 is Assault by blunt object by spouse or domestic partner.

    • Key points: Injury and poisoning

      • There were around 3,000 injury-related deaths in 2017 and 188,103 injury-related hospitalisations in 2018-19 in NSW.

      • Injury and poisoning is the leading cause of death among people aged 5 to 44 years.

      • Males have much higher rates of death and hospitalisation than females for all major injury causes, except for falls among older people.

      • The rate of hospitalisation for injury and poisoning in Aboriginal people was 1.7 times that of non-Aboriginal people in NSW in 2018-19.

      • Rates of death and hospitalisation from injury and poisoning are higher in remote and regional areas than in metropolitan areas.

    • Introduction: Injury and poisoning

      Definition and classification systems

      Injury can be described by the single or multiple body regions which are affected by the injury, by the type of injury itself or by an agency which caused the injury.

      Examples of the injuries described by body regions are: injuries to the head, injuries to the hip and thigh or injuries involving multiple body regions.

      Types of injury are: superficial injury (such as abrasion, contusion, insect bite), open wound (animal bite, cut, laceration, puncture wound), fracture (closed or open, which refers to the surface of skin), dislocation, sprain or strain, injury to nerves and spinal cord, injury to blood vessels, injury to muscles, fascia and tendon, crushing injury, traumatic amputation, injury to internal organs.

      Examples of environmental events and circumstances causing injury, poisoning or other adverse events are: transport accidents, falls, exposure to electrical current, exposure to forces of nature, assaults, intentional self-harm, complications of medical and surgical care. This classification of injury and poisoning is the most important in prevention planning. These events are also known as 'external causes' of the injury.

      Injury and poisoning burden of disease in Australia

      Injury has a major, but often preventable, influence on Australia’s health. It affects Australians of all ages and is the greatest cause of death in the first half of life. It leaves many with serious disability or long-term conditions. Injury was estimated to account for 8.5% of the burden of disease in 2015.

      For each person who dies of injuries there are several thousand individuals who survive and are left with permanent disabilities. Hospitalisation data provide an indication of the incidence of the more severe injuries.

    • Interventions: Injury and poisoning

      Injury prevention involves the collaboration of governments, the private sector and communities in order to create safer environments and cultures.

      Effective injury prevention strategies have been developed for a wide range of potential causes of injury. For example, balance and strength training is effective in reducing falls in older people, fencing around private swimming pools has reduced childhood drownings, and seat-belt and drinking-driving legislation together with measures relating to vehicle and road design have greatly increased road safety.
