The Effect of Large Versus Small Clog Size on Emergency Response Time

Netherlands50 participantsStarted 2020-02-20

Plain-language summary

In many hospitals, clogs, usually white, are provided for healthcare workers. In our hospital, health care professionals from the department of intensive care medicine may be summoned to an emergency situation on a 24/7 basis. Clogs are thought to be of importance for running. Although clogs are available in several sizes, clog size is typically left to the discretion of the individual healthcare worker. Interestingly, The primary goal of this randomized controlled trial is to assess if wearing large size clogs as compared to small size clogs results in increased running speed. Participants will be randomized to small versus large clog size using a using randomly permuted blocks stratified by gender. Following randomization, participants will wear the clogs of allocated size and complete a standardized running course. The primary endpoint is the time taken to complete the course. The enrolment of 50 subjects would provide 80% power to show a 5-second difference in the response time at an average response time of 30 seconds with a 6 second standard deviation. The ethical committee judged the study protocol exempt from extensive review.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
