Plain English Summary
Background and study aims
Computer keyboards in hospital wards are a potential source of cross infection between staff and patients. We helped design and introduce flat keyboards to wards with a cleaning alarm but over time the alarm is neglected. Therefore additional measures to reduce keyboard contamination are needed. This study aims to determine if a moving box on the screen to remind users to clean the keyboard is more effective than the present flashing light or whether a light-activated coating on the keyboard to kill bacteria is effective without any further prompts to cleaning.
Who can participate?
Participants will be the users of the keyboards i.e. medical, nursing and paramedical staff.
What does the study involve?
Patients are not involved. Ten keyboards will have software loaded that gives a moving box on the computer screening when cleaning has not been performed for 12 hours. This can only be turned off by cleaning the keyboards. Another ten keyboards will have a coating that kills bacteria in visible light. All will be measured daily for bacterial counts against control keyboards.
What are the possible benefits and risks of participating?
The possible benefits are reduced keyboard contamination and potentially less transmission to patients. The disadvantage would be having to clean the keyboard in order to use the computer.
Where is the study run from?
The study is run from Microbiology department at University College London Hospitals (UCLH).
When is study starting and how long is it expected to run for?
The study will start on 5th May 2012 and run for up to 3 months.
Who is funding the study?
The study is funded by the Academic Health Sciences Centre and University College London Business (UCLB).

| Scientific title | Testing software compliance management of Esterline® Medigenic® Keyboard and assessment of the microbiological efficacy of photolytic keyboards in the clinical ward environment: randomised comparisons with routine manual cleaning |
| Study hypothesis | Using of software to prompt cleaning of the keyboard or addition of a bactercidal coating reduces contamination with hospital pathogens |
| Ethics approval(s) | Not provided at time of registration |
| Condition | Hospital-acquired infection |
| Intervention | Software installed that shows a box on the screen when keyboard not cleaned for 12 hours and photolytic coating applied to other keyboards that reduces contamination when exposed to standard artificial light. All keyboards will be measured daily for bacterial counts against control keyboards. |
| Intervention type | Other |
| Primary outcome measure | Total viable count of bacteria on keyboard surface at fixed time each day during trial |
| Secondary outcome measures | Number of hospital pathogens [Methicillin-resistant Staphylococcus aureus (MRSA), coliforms, enterococci] |
| Overall study start date | 05/05/2012 |
| Overall study end date | 15/07/2012 |
| Reason abandoned (if study stopped) | Lack of staff/facilities/resources |
