Long-term control of vancomycin-resistant Enterococcus faecium at the scale of a large multihospital institution: a seven-year experience.

Repeated outbreaks of vancomycin-resistant Enterococcus faecium (VRE) occurred between 2004 and 2010 in Assistance Publique--Hôpitaux de Paris (AP-HP), a 23,000-bed multi-hospital institution. From August 2004 to December 2005, the French guidelines for preventing cross-transmission of multiresistant bacteria were applied. Because the number of VRE cases continued to increase, an institutional control programme was implemented from January 2006 onwards: it foresees stopping transfer of VRE and contact patients, separating VRE and contact patients in distinct cohorts, intervention of a central infection control team to support local teams, and quick application of measures as soon as first VRE cases are identified. Between August 2004 and December 2010, 45 VRE outbreaks occurred in 21 of the 38 AP-HP hospitals, comprising 533 cases. Time series analysis showed that the mean number of cases increased by 0.8 cases per month (95% confidence interval (CI): 0.3 to 1.3, p=0.001) before, and decreased by 0.7 cases per month after implementation of the programme (95% CI: -0.9 to -0.5, p<0.001), resulting in a significant trend change of -1.5 cases per month (95% CI: -2.1 to -0.9, p<0.001). The number of cases per outbreak was significantly lower after implementation of the programme. A sustained and coordinated strategy can control emerging bacteria at the level of a large regional multihospital institution.

Assessing the benefit of the 72-hour antibiotic therapy reassessment documentation.

OBJECTIVES: To assess the documentation of the 72-hour antibiotic therapy reassessment in medical records. METHODS: One-day prevalence evaluation of curative antibiotic therapies≥72hours. The documentation of the reassessment was defined according to three criteria: (1) "clear" documentation (clinical or microbiological comment associated with a comment on the need to adjust the antibiotic therapy or on the lack of need); (2) "tacit" documentation (only based on a clinical or microbiological comment); (3) no documentation. RESULTS: We assessed 114 antibiotic therapies in 26 hospital departments. A clear reassessment at 72hours was observed in only 45 (39%) records and 31 (27%) records had no reassessment. The planned duration of treatment was written in 63 (55%) records. At 72hours, among the 71 antibiotic therapies with a microbiological documentation, 69 (97%) were active and 44 (62%) had a narrow spectrum. Among the 48 antibiotic therapies with a broad spectrum on day 1, only 21 (44%) benefited from a de-escalation at 72hours. A clearly recorded reassessment at 72hours was associated with de-escalation (P=0.025) and the prescription of a planned duration of treatment was associated with antibiotic therapy compliance with local or national guidelines (P=0.018). CONCLUSION: Although reassessment was observed in 73% of records, it was correctly recorded at 72hours in only 39% of cases. The documentation of the reassessment and the prescription of a planned duration were associated with a better quality of antibiotic prescription (de-escalation, compliance with guidelines) and are relevant indicators for monitoring the proper use of antibiotics.
