Recent research into the cleanliness of computer input devices within the health sector has revealed how bacteria can accumulate and spread within hospital wards. The studies show that keyboards and mice can play a part in the proliferation of common hospital infections.

Results from the primary research undertaken by Dr Peter Wilson at University College London Hospital conclude that caregivers frequently touch keyboards immediately after patient-related procedures without first performing hand hygiene. Staff then touch the keyboard or mouse and pass bacteria to other patients. Alarmingly, the research states that up to 25% of computer keyboards in wards are contaminated with MRSA and other pathogens, regardless of their design.

Claire Burke is a director of Keep IT Clean, a specialist IT equipment cleaning company with contracts in the health sector. "Proper cleaning of IT equipment is becoming more and more essential to the health sector, particularly as the use of keyboards and mice in clinical areas are on the increase with the introduction of electronic patient records. Research from the University of Arizona shows that 'deep cleaning' a keyboard can reduce the number of bacteria per square inch from typically more than 3,000 to just a trace."

With computer keyboards and mice representing a high contact area for all staff which can be a source of the spread of bacteria without direct patient contact, the responsibility for keyboard cleaning is often in doubt or overlooked. Other equipment including telephones can also harbour bacteria.

Whilst helping to limit the spread of infection, regular IT cleaning also extends equipment lifetime, helps to project a professional image and improves staff morale by showing that their wellbeing and that of the patients is a priority.
