  1. The control of hyperendemic glycopeptide-resistant Enterococcus spp. on a haematology unit by changing antibiotic usage.

    Article - En anglais

    The rectal carriage of glycopeptide-resistant Enterococcus spp. (GRE) had been established at approximately 50% in a series of prevalence studies on a busy haematological malignancy unit.

    The aim of this study was to reduce the chance of patients acquiring GRE.

    A prospective three-phase sequential study was performed.

    In Phase 1, the acquisition rate of GRE detectable by rectal swab was measured without any intervention for a period of 4 months.

    For the following 8 months (Phase 2), the first-line treatment for febrile neutropenic episodes was changed from monotherapy with ceftazidime to piperacillin/tazobactam.

    In addition, an intense education programme was introduced to improve hygiene to reduce the risk of case-to-case spread.

    In the final 4 months (Phase 3), ceftazidime was again used as the first-line antimicrobial, while continuing the same level of training in relation to hygiene.

    The carriage of GRE was measured from rectal swabs done weekly.

    During the initial 4 months, at any time, 40-50% of patients in the unit were colonized with GRE, and 43 of 75 (57%) new patients initially negative for GRE acquired it within 6 weeks of their admission.

    In Phase 2,25 patients out of 129 (19%) acquired GRE, with the acquisition rate falling progressively so that in the last 3 months, only one new patient acquired GRE (logrank comparison of probabilities for cohort 1 vs cohort 2b : P<0.0001). (...)
