RESUMEN
BACKGROUND: Some electronic hand hygiene (HH) monitoring systems require a benchmark of HH opportunities. To establish a benchmark, we measured rates of HH opportunities among general surgery patients at a tertiary care hospital. METHODS: Trained observers recorded HH opportunities for newly admitted patients daily for up to 5 days. We used multivariable logistic regression to assess the relationship between patient variables and the HH opportunity rate. A subset of observed HH events was compared to event data from an electronic HH monitoring system. RESULTS: We observed 2,404 HH opportunities over 677.4 care-hours for 23 patients (median 3.25 per hour; IQR 2.2-4.7, range 0-13). Rates of HH opportunities were significantly higher on admission day 1, for sessions starting before 9 AM, and for patients without roommates. HH was performed using alcohol-based hand rub from dispensers at the door to a patient's room more often than bedside or pocket dispensers (72.7% vs 20.8% or 5.1%). Electronic dispenser event counts did not match observed event counts. CONCLUSIONS: Our results provide a benchmark HH opportunity rate for general surgery patients, and highlight the importance of validating electronic HH event counts. Further research is needed to determine which patient factors affect HH opportunity rates.

A systematic appraisal of evidence suggests that male patients in hospital may be at higher risk for bacteremia following urinary catheter-associated bacteriuria than females. Other risk factors include immunosuppressant medication, red blood cell transfusion, neutropenia, malignancy, and liver disease.

The present study aimed to determine the frequency of methicillin-resistant Staphylococcus aureus (MRSA)-positive clinical culture among hospitalized adults in different risk categories of a targeted MRSA active surveillance screening program and to assess the utility of screening in guiding empiric antibiotic therapy. We completed a prospective cohort study in which all adults admitted to non-intensive-care-unit locations who had no history of MRSA colonization or infection received targeted screening for MRSA colonization upon hospital admission. Anterior nares swab specimens were obtained from all high-risk patients, defined as those who self-reported admission to a health care facility within the previous 12 months or who had an active skin infection on admission. Data were analyzed for the subcohort of patients in whom an infection was suspected, determined by (i) receipt of antibiotics within 48 h of admission and/or (ii) the result of culture of a sample for clinical analysis (clinical culture) obtained within 48 h of admission. Overall, 29,978 patients were screened and 12,080 patients had suspected infections. A total of 46.4% were deemed to be at high risk on the basis of the definition presented above, and 11.1% of these were MRSA screening positive (colonized). Among the screening-positive patients, 23.8% had a sample positive for MRSA by clinical culture. Only 2.4% of patients deemed to be at high risk but found to be screening negative had a sample positive for MRSA by clinical culture, and 1.6% of patients deemed to be at low risk had a sample positive for MRSA by clinical culture. The risk of MRSA infection was far higher in those who were deemed to be at high risk and who were surveillance culture positive. Targeted MRSA active surveillance may be beneficial in guiding empiric anti-MRSA therapy.
