چکیده انگلیسی

An ideal computer keyboard for clinical use would be easily cleanable and cleaned by staff, meet acceptable levels of usability, and not attract hospital bacteria. Methods In vitro studies were performed to demonstrate bacterial transfer between keyboard surfaces and gloves. This was followed by a usability study and a controlled trial of keyboard contamination in an intensive care unit both with and without an alarm to indicate the need for cleaning. Eight cleanable keyboards were placed at random beds and compared with standard keyboards. Results Bacteria were most easily removed from a flat silicone-coated surface. The total viable count on flat keyboards with an alarm was lower than that on standard or other cleanable keyboards (median, 19 colony-forming units [cfu] (interquartile range, 7 to 40 cfu), n = 34; 65 cfu (33 to 140 cfu), n = 50; and 40 cfu (21 to 57 cfu), n = 80). Compliance with hand hygiene before touching the standard keyboard was 27%, but the alarmed keyboard was cleaned on 87% of occasions on which the alarm was triggered. The usability study found the flat profile of the cleanable keyboard did not interfere with routine use, except for touch-typing. Conclusion The flat keyboard with an alarm is easy to clean, and it use is associated with better cleaning compliance. With the advent of electronic patient records, the numbers of computer keyboards and mice in use in clinical areas are on the increase. Caregivers frequently touch keyboards immediately after patient-related procedures without first performing hand hygiene.1 They then touch other keyboards without disinfecting their hands, possibly passing bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), to other patients. Domestic workers do not clean electronic equipment, and compliance with cleaning by nurses is poor (9.3%).1 Up to 25% of computer keyboards in wards are contaminated with MRSA and other pathogens, regardless of their design. 1, 2 and 3 The hands of staff are believed to be the main vector for transfer of pathogens.3 The aim of this study was to develop a user-friendly computer keyboard to which bacteria are not readily transferred (and can be easily removed) and that can be easily cleaned.

The flat keyboard with an alarm is easy to clean, and it use is associated with better cleaning compliance. With the advent of electronic patient records, the numbers of computer keyboards and mice in use in clinical areas are on the increase. Caregivers frequently touch keyboards immediately after patient-related procedures without first performing hand hygiene.1 They then touch other keyboards without disinfecting their hands, possibly passing bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), to other patients. Domestic workers do not clean electronic equipment, and compliance with cleaning by nurses is poor (9.3%).1 Up to 25% of computer keyboards in wards are contaminated with MRSA and other pathogens, regardless of their design. 1, 2 and 3 The hands of staff are believed to be the main vector for transfer of pathogens.3 The aim of this study was to develop a user-friendly computer keyboard to which bacteria are not readily transferred (and can be easily removed) and that can be easily cleaned.
