  1. Gillian Frost, Epidemiologist, HSL Health, Safety and Risk Management Network 2016 The SSHeW study: Stopping Slips among Healthcare Workers

  2. Outline • Background and motivation • Study design • Participant journey • Timeline

  3. Why slips at work? Kinds of specified injury to employees, 2014/15p (RIDDOR) Source: Health & Safety Executive 42% Over-seven-day injuries to employees, by kind of injury, 2014/15p (RIDDOR) Source: Health & Safety Executive 24%

  4. Impact Source: Health & Safety Executive

  5. Why healthcare? Numbers and rates of specified injuries due to slips and trips, by industry, 2014/15p (RIDDOR) Over-7-day injuries to employees, due to slipping, tripping, by industry sector, 2014/15p (RIDDOR) Source: Health & Safety Executive

  6. The problem Flooring? • Perceptions of hygiene • Cost • Logistics and disruption • Some people need to shuffle Source: Health & Safety Executive • Community workers

  7. The solution Slip Resistant Footwear! (but where’s the evidence?)

  8. Previous research • An observational study in the USA found that restaurant workers who wore slip resistant shoes were 54% less likely to slip • A before and after study among fishermen suggested slip resistant boots led to a reduction in slips • A cluster randomised controlled trial of food service employees in the USA found a 64% reduction in slips

  9. Which shoes are ‘slip resistant’? • Performance of ‘slip resistant’ footwear can vary widely

  10. GRIP rating scheme • Based on HSL’s ramp test

  11. GRIP rating scheme For more information visit: www.hsl.gov.uk/products

  12. GRIP case studies • Utilities companies reduced lost time incidents from 74 to 1 • Supermarket invested £600,000 and saved £1m in claims alone in the first year • Pet food manufacturer eliminated slips and saved £12,000 within the 6 month trial period • Oil company changed their footwear and slips increased dramatically. They now only buy footwear if it’s been tested by HSL.

  13. Aim To confirm, in a large pragmatic trial, that GRIP-rated slip resistant footwear can reduce slips among healthcare workers (+ economic analysis)

  14. Study design • Randomised controlled trial – gold standard, best evidence • Recruit individuals and randomly allocate them to either • Intervention: Receive a pair of GRIP-rated slip resistant footwear • Control: Continue to wear their usual shoes

  15. Study population • NHS employees • UK’s largest employer • Has a high number of slip injuries • Flooring where slip resistant footwear performs well • Range of occupations – for example, nurses, kitchen staff, porters, community workers • 4,400 employees across 4/5 trusts • Trusts will run one after the other

  16. Data collection • 16/18 week duration • Primary outcome • Slips (whether or not they lead to a fall/injury) • Collected by weekly text message • Paper diary to aid recall

  17. Data collection: Secondary outcomes • Consequence/injury; reason for slip; location • Follow-up texts? • Follow-up telephone calls? • Collect diaries? • Questionnaire at the end? • Compliance • Monthly texts • Questionnaire at the end • Telephone/face-to-face interviews

  18. Data collection: Secondary outcomes • Footwear testing • To assess the typical service life of the GRIP rated footwear • 15 pairs tested at 6, 9 and 12 months (45 pairs in total) • Cost effectiveness

  19. Participant timeline Week 0 Week 6 Week 18 Recruitment Run-in period Main study period Run-in Randomise Distribute • Stalls • Emails • Posters • Twitter • Informed consent • Baseline questionnaire • Assess eligibility • Slip diary • Weekly texts begin • Systems check • Baseline data • Compliance check • Weekly texts continue • Follow-up of slips • Monthly compliance texts(footwear group only) • Compliance questionnaire /interviews (footwear grouponly) • Footwear for control group

  20. Trust timeline 1 year The plan Trust 1 Trust 2 Trust 3 Trust 4 The reality Trust 1 Trust 2 Trust 3 Trust 4 Trust 5…

  21. Internal pilot • Will involve 2 trusts and 800 participants • Objectives: • To test and refine the recruitment strategy • To check the sample size calculations • To check loss to follow-up • To address and explore any issues regarding footwear compliance • Will have defined stop/go criteria

  22. Right now… • Early stages (started October 2016) but progressing quickly • Putting together study protocol and related documentation • In talks with various trusts • Hoping to start the pilot in the New Year • Due to complete April 2019

  23. Summary • Slips are the main source of injury in the workplace • They can have serious consequences for the individual and result in large cost to industry • Particular problem in healthcare

  24. Summary • This study will provide high quality evidence on the effectiveness and cost-effectiveness of slip resistant footwear at preventing slips in healthcare • Other industries could use this evidence when considering use of slip resistant footwear

  25. Thank you for listening Do you know a trust that may be interested in taking part or would you like more information? Gillian Frost, Epidemiologist, HSLGillian.Frost@hsl.gsi.gov.uk Mark Liddle, Falls Prevention Specialist, HSLMark.Liddle@hsl.gsi.gov.uk Any questions?
