Norovirus has been associated with excess deaths. A retrospective study of mortality following norovirus enteritis (NVE) was undertaken. All hospitalized adult patients with a stool sample positive for norovirus genogroup II on polymerase chain reaction, treated at Sahlgrenska University Hospital, Gothenburg, Sweden between August 2008 and June 2009, were included as cases (N = 598, aged 18-101 years). ⋯ In cases aged > 80 years, mortality was higher in those with community-onset NVE (N = 64) compared with hospital-onset NVE (N = 305) (81.2% vs 90.2% alive at Day 30, respectively; P < 0.05), and compared with controls (N = 128) (81.2% vs 91.4% alive at Day 30, respectively; P < 0.05). Median length of hospital stay was 20 [interquartile range (IQR) 12-29] days for cases with hospital-onset NVE, and seven (IQR 2-13) days for controls (P < 0.001). In conclusion, community-onset NVE requiring hospitalization was associated with higher mortality compared with hospital-onset NVE and matched controls in hospitalized elderly patients.

Multicenter Study
Ventilator-associated pneumonia in intensive care units in Hubei Province, China: a multicentre prospective cohort survey.
A multicentre prospective cohort study was performed in 17 intensive care units (ICUs) in tertiary care hospitals in Hubei Province, China. Ventilator-associated pneumonia (VAP) was defined according to modified criteria from the published literature. Among 4155 ventilated patients, the crude incidence and incidence rate of VAP were 20.9% and 28.9 cases per 1000 ventilator-days. ⋯ Of all Staphylococcus aureus isolates, 45.7% were meticillin resistant. Rates, risk factors and causal pathogens of VAP in ICUs in Hubei differ from those reported from developed countries. These data show the need for more effective infection control interventions in Hubei, China.

We report an evaluation of the utility of serum procalcitonin (PCT) measurement as an additional diagnostic tool to support initiating or withholding antibiotics in clinical situations where there is a clinical suspicion of infection but the diagnosis is uncertain. During a six-month period, 99 patients on the medical admission unit (MAU) with suspected infection, and 42 patients on the intensive care unit (ICU) with clinical signs or physiological parameters suggesting possible new infection, had serum PCT concentration measured with the result available within 90min of the request. The test was initiated by the microbiology/infection team during clinical consultations to support the antibiotic decision. ⋯ Without the PCT value it is likely that all of these patients would have received empirical antibiotics. Reduction in unnecessary antibiotic usage was made without any adverse effects on these patients and there was a clear reduction in antibiotic prescribing with cost reduction implications. PCT has the potential to become a valuable tool in antibiotic management.
