Before any contact precautions can be implemented, newly identified MRSA carriers frequently have contaminated their environment with MRSA and have contamination of commonly examined skin sites. In hospitals that perform active surveillance, strategies are needed to minimize delays in screening or to preemptively identify patients at high risk for disseminating MRSA.

In a Veterans Affairs medical center, 39% of healthcare facility-onset, healthcare facility-associated Clostridium difficile infections had their onset in the affiliated long-term care facility (LTCF). Eighty-five percent of LTCF-onset patients had been transferred from the hospital within the past month. Delays in diagnosis and treatment were common for LTCF-onset patients.

In a prospective study involving 115 patients with methicillin-resistant Staphylococcus aureus nares carriage, we found that skin and environmental contamination with methicillin-resistant S. aureus was as likely among individuals whose S. aureus carriage was identified only through active surveillance as it was among those individuals whose S. aureus carriage was identified clinically, which suggests that strategies to limit transmission must address colonized patients, as well as infected patients.

Background/objective: Patients with spinal cord injury (SCI) are at risk of acquiring colonization with Clostridium difficile and vancomycin-resistant Enterococcus (VRE) due to prolonged hospitalization and frequent antimicrobial use. We examined the frequency of stool, skin, and environmental contamination with C. difficile and VRE in hospitalized patients with SCI. Methods: We performed a cross-sectional study of 22 hospitalized patients with SCI with no symptoms of C. difficile infection. Stool samples, skin, and environmental sites were cultured for C. difficile and VRE, and polymerase chain reaction ribotyping was performed for C. difficile isolates. Fisher's exact test was used to compare the proportions of skin and environmental contamination among stool carriers and non-carriers. Univariate analysis was used to assess factors associated with asymptomatic carriage of C. difficile. Results: Of 22 asymptomatic patients, 11 (50%) were asymptomatic carriers of toxigenic C. difficile and 12 (55%) were carriers of VRE. In comparison with non-carriers, asymptomatic carriers of toxigenic C. difficile had higher rates of skin (45 versus 9%) (P = 0.07) and environmental contamination (55 versus 9%) (P = 0.03) and longer length of stay (median, 57 versus 6 days; P = 0.04). A majority of skin and environmental C. difficile isolates from individuals were identical to isolates from stool. In comparison with non-carriers, patients with VRE stool colonization had non-significant trends toward more frequent skin (27 versus 9%) and environmental (18 versus 9%) contamination. Conclusion: Asymptomatic stool carriage of toxigenic C. difficile and VRE was common on an acute-care SCI unit. Asymptomatic carriers of toxigenic C. difficile had frequent skin and environmental contamination, suggesting the potential to contribute to transmission.

At a safety net hospital, patients who survived their initial sepsis hospitalization had a 30-day readmission rate to our institution of 22.6% that is comparable to rates described in prior studies. Readmission was commonly due to infection. Factors associated with readmission included multiple comorbid medical conditions, bacteremia, and being discharged with a vascular catheter. Further studies in this population are needed to determine potential modifiability of these risk factors in an attempt to reduce sepsis readmissions.
