Description

Age-standardized rate of hospitalization in a general hospital due to self-injury, per 100,000 population.

For further details, please see the General Methodology Notes.

Interpretation

Lower rates are desirable.

Using the available data sources, capturing intention is difficult. This indicator cannot distinguish whether or not the self-injury was intended to result in death (self-harming or suicidal behaviour). In addition, this indicator might provide biased estimates of the true number of hospitalizations for self-injury, due to the manner in which intent is captured in the data sources available. For example, poisoning can be coded as "unintentional"—an overdose—or "undetermined"—reflecting an uncertainty between unintentional and intentional motives. Neither unintentional nor undetermined injuries were included in this indicator, even though it is assumed that a small number of these cases were, in fact, intentional.

Inclusions:
1. Self-injury is identified by the following external cause of injury codes with a diagnosis type of 9: ICD-10-CA X60 to X84
Exclusions:
1. Cases of self-injury involving outpatient treatment in hospital emergency departments or other medical facilities or completed suicide prior to hospital admission

<div role="button" class="expandableTitle" aria-controls="backgroundRegion">Background, Interpretation and Benchmarks</div>
Rationale

Self-injury is defined as a deliberate bodily injury that may or may not result in death. This type of injury is the result of either suicidal or self-harming behaviours, or both. Self-injury can be prevented, in many cases, by early recognition, intervention and treatment of mental illnesses. While some risk factors for self-injury are beyond the control of the health system, high rates of self-injury hospitalization can be interpreted as the result of a failure of the system to prevent self-injuries that are severe enough to require hospitalization.

Interpretation

Lower rates are desirable.

Using the available data sources, capturing intention is difficult. This indicator cannot distinguish whether or not the self-injury was intended to result in death (self-harming or suicidal behaviour).

Caveats and Limitations

This indicator does not include cases of self-injury involving outpatient treatment in hospital emergency departments or other medical facilities or completed suicide prior to hospital admission. Thus this indicator cannot be used to estimate the prevalence of self-injury in the general population. Also not included are patients who were institutionalized in a psychiatric hospital and were self-injured during their stay but did not require admission to a general hospital. For a broader estimate of self-injury, please refer to the In Focus section of Health Indicators 2012.

Trending Issues

Weyburn Mental Health Centre in Saskatchewan is not included in all mental health–related indicators as requested by the facility. As a result, rates for Sun Country Health Region (4701) in 2009 are not comparable with those reported in subsequent years.

Brant Community Healthcare System: Brantford General Hospital did not submit its 2009–2010 data to the Ontario Mental Health Reporting System as of the reporting deadline; therefore, it is not included in the indicator calculation. Rates for North East Local Health Integration Network (3513) are not comparable with those reported in subsequent years.
