Plain English Summary

Background and study aims
Slips and falls are the main cause of accidents in the workplace. Last year, over 100,000 people hurt themselves as a result of having a slip, trip or fall at work. This is about 40% of all of the injuries which had to be reported to the Health and Safety Executive. These injuries can have a major effect on the individual as well as on employers due to lost days at work. It has been estimated that one million days were taken off work in 2012/13 due to injuries caused by slips, trips or falls. People working in health and social care report the highest numbers of workplace slips and trips, and hospital staff are more likely to slip because of the smooth flooring they walk on, which becomes slippery when it is wet or dirty.One possible way of reducing the number of slips people have could be for them to wear slip resistant shoes. The aim of this study is to find out if slip resistant shoes can stop NHS staff from slipping, falling or hurting themselves.

Who can participate?
Staff working in NHS trusts who have to follow a workplace dress code and who have a mobile phone.

What does the study involve?
After agreeing to take part, participants fill in a questionnaire and reply to text messages reporting if they have a slip at work. Those who complete the texts are then randomly allocated to one of two groups using a computer program. Those in the first group receive one free pair of slip resistant shoes to wear at work for 14 weeks. Those in the second group are asked to wear their own work shoes for the duration of the study. These participants are offered a pair of the slip resistant shoes at the end of the study period. All participants receive a text message once a week for 14 weeks to ask if they have had a slip in the last week. The first time a participant reports a slip by text message, they are telephoned by a researcher to obtain further details of the incident. Participants are given a paper diary in which to record details of any slips, falls or injuries. Once a month people wearing the slip resistant footwear are asked how often they are wearing them via text message. Participants are also sent a paper questionnaire at 14 weeks to collect further information. Some participants are asked to return their footwear so that it can be tested to see how worn the soles are.

What are the possible benefits and risks of participating?
There are no notable benefits or risks involved with participating.

Where is the study run from?
1. Leeds Teaching Hospitals NHS Trust (UK)
2. Cheshire and Wirral Partnership NHS Foundation Trust (UK)
3. York Teaching Hospitals NHS Foundation Trust (UK)

When is the study starting and how long is it expected to run for?

Intervention

All eligible consenting participants, who return a completed baseline questionnaire, will be sent a weekly text message requesting slips data. Eligible participants who return a valid baseline questionnaire and respond to at least two of the data collection texts requesting data on slips, irrespective of whether they experienced a slip, will be randomised into the trial. Participants will be randomly allocated using the York Trials Unit secure web-based randomisation system based on an allocation sequence generated by an independent data systems manager at the York Trials Unit, who is not involved in the recruitment of participants. The randomisation will be stratified by NHS Trust, and block randomisation within Trust will be used with variable block sizes. Participants will be allocated 1:1 to either the control or intervention group.

Control group: Participants will be asked to wear their usual work footwear for 14 weeks after they are randomised into the study. At the end of this period they will be offered a free pair of slip resistant shoes provided by 'Shoes for Crews' and paid for by the Trust.

Intervention group: Participants will receive one pair of 5-star GRIP rated slip resistant footwear provided by 'Shoes for Crews' free of charge to the participant. Footwear will be selected from a trial specific catalogue.

All participants will be followed up for 14 weeks during this time they will receive a weekly text asking for slips data. Participants reporting their first slip will be phoned and further information collected. In addition the intervention group will receive a monthly text asking about footwear compliance. All participants will be sent a questionnaire 14 weeks after randomisation to collect secondary outcome data. We will evaluate the wear on the sole of the shoes. 15 consenting participant will be asked to continue wearing their intervention footwear beyond the trial period for a further 6, 9 and 12 weeks (45 in total). A qualitative study will be undertaken to explore the acceptability of the footwear, reasons for wearing or not wearing the shoes and views on the impact of the footwear.
