Injuries in Public Swimming Pools
• Pilot study results
![Page 12: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/12.jpg)
Background
• Most studies report drowning fatalities in public and residential swimming pools
• Little information about non-fatal drowning incidents and other major/ minor incidents in commercial aquatic facilities
• Information to help improve the defined role of the lifeguard, facility design issues and operational issues covered by the GSPO
• Study commenced 2005
![Page 13: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/13.jpg)
Aims
The aims of the pilot study were to describe: • Major and minor incidents that occur at public
swimming pools • Locations within pools where the incidents
occur • The type of medical treatment provided
![Page 14: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/14.jpg)
Methodology
• 18 facilities – 12 metro (9 year round, 3 seasonal) – 6 regional (3 year round, 3 seasonal)
• Major/ minor incident reports collected between July 1 and Dec 31 2004 – 6 months data from year round pools – Seasonal pools provided all reports within
that period in which they were open

Rate of Injury/Incidents
• Total number of incidents = 1715 • Incidence rate of 142 per 100,000 pool
visitations • Similar incidence rate in metro vs regional
pools (144 vs 128) • Greater rate of incidents at year round vs
seasonal pools (145 vs 84)

• Wound management (45%) • ICE (25%) • Combination of treatments (14%) • Referred elsewhere (4%) • Rescues (2%) • Oxygen (1.5%) • Ambulance (0.3%)

Treatment Time
• Treatment time ranged from 5-110 minutes • Average treatment time 22 minutes
![Page 23: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/23.jpg)
Discussion
• Incidence rate similar to a previous study in Vic, greater than study in WA – difficult to compare studies due to differences
in methodology • unclear from these studies how/ whether all data
collected • different time frames of data collection
![Page 24: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/24.jpg)
Discussion
• Lack of gender differences may reflect – participation rates – lack of data
• Age differences may reflect – participation rates – types of activities undertaken and behaviour
patterns
![Page 25: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/25.jpg)
Discussion
• A quarter of incidents occurred during supervised swimming lessons
• Types of incidents provide an indication of the activities of lifeguards and the time spent in these activities (distraction from other activities)
• How does this impact on training and staffing?
![Page 26: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/26.jpg)
Strengths and Limitations
• First study to provide detailed information about incidents in public swimming pools
• Missing / non-reported data due to lack of consistency in information collected on report forms
• Missing data about age and gender • Lack of information about those visiting
centre for comparisons/ better determination of incidence rate
• Only six months of data collected- missing part of the Summer period
![Page 27: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/27.jpg)
Getting the most from your data
• Decide what to collect and why? • Who is the information for and how will it be
used? • Ensure quality of data collected
– Complete forms – Key information required
• Staff training in completion of forms – Create understanding of importance of quality
data
![Page 28: Managing and Using Injury Data - Life Saving Victoria · 2018. 7. 3. · Managing and Using Injury Data . Dr Bernadette Matthews Manager Research & Injury Prevention . Injury Data](https://reader036.vdocument.in/reader036/viewer/2022071415/6110b1ec47d5701ab7462b4b/html5/thumbnails/28.jpg)
Future Directions
• State-wide facility incident database – Long-term data collection
• What data available? – Monitor trends – Standardised analysis & reporting – Industry report
• Top level findings (no individual facilities named) • Individual facility report
– Comparison to grouped state data
– Funding opportunities

Future Directions
• State-wide facility incident database – Collaboration with academic institutions – Ethics and confidentiality
• De-identified data – Collection of information from smaller facilities
