Information about the data
This indicator reports unintentional hazardous substances-related hospital discharges using data from 2001 onwards. This indicator is an analysis of the most recent data available from the National Minimum Dataset. Data has been pooled to give sufficient numbers for analysis where appropriate. For more information on the list of ICD-10 that are covered in this analysis, see metadata.
Most hazardous substances injuries are considered acute (short-term, intense exposure) rather than chronic (prolonged low intensity exposure) events. Chronic harm from hazardous substances is hard to measure because it is often difficult to determine what caused the harm. This means that data on chronic harm is hard to find and likely to underestimate the number of people affected.
