The outer surfaces of included charts were sampled by one experienced investigator with sterile cotton swabs rinsed with normal saline.<h4>Results</h4>For general wards and special units, the overall sampling rates were 81.8% (455/556) and 85.6% (107/125) (p = 0.316); the incidence of chart contamination was 63.5% and 83.2%, respectively (p<0.001). Except for obstetric-gynecologic charts, the incidence was significantly higher in each and in all ICUs than in corresponding wards. Coagulase-negative staphylococci was the most common contaminant in general wards (40.0%) and special units (34.6%) (p>0.05). Special units had a significantly higher incidence of bacterial contamination due to Staphylococcus aureus (17.8%), Methicillin-resistant Staphylococcus aureus (9.3%), Streptococcus viridans (9.4%), Escherichia coli (11.2%), Klebsiella pneumoniae (7.5%), and Acinetobacter baumannii (7.5%). Logistic regression analysis revealed the incidence of chart contamination was 2- to 4-fold higher in special units than in general wards [odds ratios: 1.97-4.00].<h4>Conclusions</h4>Noting that most hospital charts are contaminated, our study confirms that a hospital chart is not only a medical record but also an important source of potential infection. The plastic cover of the medical chart can harbor potential pathogens, thus acting as a vector of bacteria. Additionally, chart contamination is more common in ICUs. These findings highlight the importance of effective hand-washing before and after handling medical charts. However, managers and clinical staff should pay more attention to the issue and may consider some interventions.Kuo-Hu ChenLi-Ru ChenYing-Kuan WangPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 9, Iss 2, p e78512 (2014)
