A survey was performed to determine the frequency of unrecognized repetitive licking of fingers while reviewing hospital charts by various healthcare professionals who, by this habit, may be putting themselves at risk of acquiring a nosocomial infection. Nine of 14 charts demonstrated the presence of Staphylococci aureus, cultures obtained from three of nine charts grew methicillin-resistant S. aureus, and six grew methicillin-susceptible S. aureus. Of the 50 healthcare professionals surveyed, five (10%) admitted to habitual repetitive licking of fingers while reviewing charts. In addition, 30 (60%) of those surveyed had observed other professionals doing so. Forty-seven (94%) acknowledged that they did not routinely wash their hands after reviewing the charts, potentially placing themselves at risk of acquiring a nosocomial infection. As an immediate consequence of this study, staff members have been encouraged to wash their hands before and after reviewing a patient's chart.
