RESUMO
AIM: To evaluate recommendations of an antibiotic stewardship (ABS) team during routine weekly visits and to analyse their implementation and reasons for non-implementation by the ward physicians. METHODS: Multiprofessional ABS Rounds (members: infectiology, microbiology, pharmacy and hospital epidemiology) were accompanied by an observer in nine intensive and peripheral wards of a university hospital (1451 beds) for eight weeks. The recommendations of the ABS team were prospectively analysed, and when these were not implemented, ward physicians in charge were asked to give reasons for non-implementation. RESULTS: A total of 262 patients were visited in the course of 359 ABS visits. A median of four physicians and one pharmacist (Q25/Q75: 4/6) participated in the ABS rounds. In 177/359 (49%) of visits, at least one recommendation for anti-infective therapy was given; the total number of recommendations made was 210. The most frequent (38%, 80/210) recommendations were related to the prescribed therapy duration. The more different the professional groups participating in the ABS rounds, the larger was the number of recommendations given (p=0.016; odds ratio=1.018 (1.003-1.033)). 62/210 (30%) of the ABS recommendations were not implemented by the ward physicians in charge. The most frequent reason (32%: 20/62) for this was the deliberate decision by the physicians to deviate from the recommended therapy. CONCLUSIONS: The high recommendation rate of 50% demonstrates the need for optimizing therapy by the ABS teams in routine practice. The larger the number of different specialists participating in single visits, the larger was the number of recommendations. Reasons for the lack of implementations need to be critically examined by both the ABS team and the ward physicians in charge.

After a single patient was transferred to Leipzig University Hospital from a hospital in Rhodes, Greece, the hospital experienced the largest outbreak due to a KPC-2-producing Klebsiella pneumoniae (KPC-2-KP) strain thus far observed in Germany. Ninety patients hospitalised between July 2010 and October 2012 were affected. In an attempt to eliminate KPC-2-KP from their digestive tracts, 14 consecutive patients (16%) were treated with a short course (7 days) of selective digestive decontamination (SDD), employing colistin (1 million units q.i.d.) and gentamicin (80 mg q.i.d.) as oral solutions, and applying colistin/gentamicin gel (0.5 g) to the oral cavity. In a retrospective analysis, these 14 SDD patients were compared with the remaining 76 patients harbouring KPC-2-KP. KPC-2-KP carrier status was followed in all 14 SDD patients by submitting stool samples to KPC-specific PCR. The mean follow-up period was 48 days (range 12-103 days). Successful elimination of KPC-2-KP was defined as a minimum of three consecutive negative PCR test results separated by ≥48 h each. Decolonisation of KPC-2-KP was achieved in 6/14 patients (43%) after a mean of 21 days (range 12-40 days), but was also observed in 23/76 (30%) of the non-SDD controls (P = 0.102). SDD treatment resulted in the development of secondary resistance to colistin (19% increase in resistance rate) and gentamicin (45% increase) in post-treatment isolates. In the control group, no secondary resistance occurred. We conclude that the SDD protocol applied in this study was not sufficiently effective for decolonisation and was associated with resistance development.
