Fühlen sich Chirurgen gerüstet für die komplexen Fragestellungen im Umgang mit multiresistenten Erregern? - Ergebnisse der Fragebogenstudie MR2

Background At the present time, there is no evidence available as to the knowledge of general surgeons regarding multi-resistant pathogens (MRP) and the rational use of antibiotic medication (antibiotic stewardship/ABS) compared with physicians from other disciplines. Methods As part of the MR2 survey (Multiinstitutional Reconnaissance of practice with MultiResistant bacteria - a survey focussing on German hospitals), a questionnaire comprising 4 + 35 items was distributed to urologists, internists, gynaecologists and general surgeons in 18 hospitals. Multivariate regression models were applied to assess the impact of each discipline affiliation on predefined endpoints. Results 456 evaluable surveys were analysed. The response rate of surgeons (156/330; 47%) and physicians from other disciplines (300/731; 41%) did not differ significantly. Based on their self-assessment, surgeons indicated a significantly lower certainty regarding the correct choice of dose, frequency and duration of antibiotic treatment (p = 0.005), the decision between intravenous or oral application (p = 0.005), as well as the accurate interpretation of microbiological reports (p = 0.023). Both surgeons and doctors from other disciplines rated their knowledge of ABS as limited. An insignificant difference was found between surgeons and non-surgeons regarding the knowledge of E. coli resistance against Ciprofloxacin in their own hospital (27.6 vs. 35.3% estimated the correct category; p = 0.114), with 64% of surgeons underestimating the local resistance rates. Both physician groups assumed that the frequent use of broad-spectrum antibiotics is substantially responsible for the increase in MRP. However, in the given case study of a highly symptomatic female patient with uncomplicated urinary tract infection, both physician groups were almost equally likely to propose treatment with a broad-spectrum antibiotic (34.0 vs. 29.3%; p = 0.331). Based on the results of the multivariate models, there were no significant differences between surgeons and non-surgeons with regard to both the attendance of training courses related to MRP/ABS over the past 12 months and the quality of discharge summaries in their hospitals regarding the correct listing of MRP. Conclusion In due consideration of the results of the MR2 survey, mandatory ABS programs should be implemented in hospitals, including regular training of physicians regardless of their discipline.
