HASS and LASS
Home & Leisure Accident Surveillance System

Unfortunately, the web database for the Home and Leisure Accident Surveillance System (HASS/LASS), which included UK accident statistics for the years 2000 to 2002, is no longer available.

The HASS/LASS annual reports that were produced for these years, as well as for 1998 and 1999, are still accessible online.

When you are searching for information in the annual reports, it is crucial that you focus on "national estimate" figures - these were the figures produced to estimate the total number of people visiting Accident and Emergency departments across the UK as a result of home and leisure accidents. (Any figures in the annual reports that are not entitled "national estimate" only show the cases counted at the 16-18 sample hospitals that took part in the data collection process).

Please see the frequently asked questions below for more details about HASS and LASS. If you require any assistance, or more detailed figures than those contained within the annual reports, please email hasslass@rospa.com

All data in HASS/LASS was collected and collated by the former Department of Trade and Industry (DTI), and RoSPA made the data accessible under contract to the DTI. We regret that RoSPA cannot accept responsibility for the accuracy, completeness or content of the information provided in the annual reports.

Q. What are HASS and LASS?
A. HASS - the Home Accident Surveillance System - and LASS - the Leisure Accident Surveillance System - are two linked databases holding details of home and leisure accidents that caused a serious enough injury to warrant a visit to hospital. They do not include road or workplace accidents. The "national estimate" figures that can be produced using HASS/LASS estimate the total number of people who visited Accident and Emergency departments across the UK as a result of home and leisure accidents. The complete HASS/LASS databases contain more than 6.8million accident records that were collected over more than 20 years (from 1978-2002), synthesising 30 different fields of information.

Q. Why were HASS/LASS set up?
A. The aim of HASS and LASS was to gain an in-depth understanding of how and why home and leisure accidents occurred so that interventions could be put into place to prevent them happening in future.
Both HASS and LASS focus on consumer products that are involved in accidents along with a wealth of information on a wide range of behavioural factors.

Each record on the database includes the following:

The identity of accident victims is confidential and will never be released.

Q. Does HASS/LASS include every home and leisure accident that took place in the UK during the recording year?
A. No. The data was taken from a sample of 16-18 accident and emergency departments in the UK and national estimates were then calculated using multipliers set for each data year. The smaller the number of HASS/LASS cases for a particular combination of variables, the less statistical confidence we have in the national estimate derived from it.

Q. Are home and leisure accident statistics still being collected?
A. On May 2, 2003 it was announced that the Department of Trade and Industry (DTI) would no longer fund the collection and publication of HASS/LASS data. To ensure that the existing data would continue to be made available to users, a complete copy of the database was handed over to RoSPA. RoSPA's Information Centre began to answer all incoming HASS/LASS enquiries from January 1, 2004, and will continue to operate this service for the foreseeable future. RoSPA campaigns for better injury data collection. See www.rospa.com/about/currentcampaigns/injury-data/ for details. A trial of a Kiosk Injury Surveillance System (KISS) began in October 2012.

Q. Will I be able to see details of individual accidents in the HASS/LASS annual reports rather than just statistics?
A. The HASS/LASS annual reports do not allow you to read details of individual accidents. To obtain this information you would need to contact RoSPA’s Infocentre which can provide de-personalised case summaries, in accordance with the principles of the Data Protection Act.

Q. Is it possible for you to provide date-based information such as the number of accidents that take place on Christmas day each year?
A. No. Unfortunately not all of the data records contain the full date and therefore any estimates of accidents would be inaccurate. We are able to provide a breakdown of accident data by month. Please contact RoSPA’s Infocentre for further details.

Q. Can I obtain regional accident data from you?
A. No. The HASS/LASS data is derived from a sample of admissions to 16-18 hospital accident and emergency departments, so there is no way of providing regional/county data, only national estimates. For the same reason, data cannot be supplied individually for Wales, Scotland, England or Northern Ireland. Only an overall UK estimate can be provided.

Q. How are the national estimates reached from the sample data?
A. Once the sample data had been taken from the 16-18 HASS/LASS hospitals, they were converted into national figures using an equation that converted the total attendances at the sample hospitals into an estimate of the total attendances at all hospitals across the country.

The smaller the number of HASS/LASS cases for a particular combination of variables, the less statistical confidence there is in the national estimate derived from it.

Q. I would like more information. Who should I ask?
A. If you require any assistance, or more detailed figures than those contained within the annual reports, please email hasslass@rospa.com
