Abstract
BACKGROUND
After a first large-scale study on multi-drug resistant organisms (MDRO) in rehabilitation facilities in 2014, the Rhine-Main network on MDRO carried out another investigation in 2019. With regard to the recently published KRINKO recommendations on multidrug resistant enterococci, now vancomycin -resistant enterococci (VRE) and multi-drug resistant gram-negative pathogens (3MRGN and 4MRGN, i. e. gramnegative organisms resistant against 3 resp. 4 groups of antiinfectiva) were investigated.
MATERIAL AND METHODS
A total of 16 hospitals took part, including one clinic for early neurological rehabilitation (ENR). Patient participation was voluntary. Rectal swabs were analyzed in a medical-microbiological laboratory (certified according to DIN ISO 15189) using standard methods (including MALDI-TOF-MS and VITEK 2 resistance testing according to EUCAST). By using the standardized questionnaire of the Europe-wide HALT examination (healthcare associated infections in long-term care facilities), patient characteristics (age, gender, hospital, surgical and MDRO medical history, Medical devices, current antibiotic therapy etc.) were collected.
RESULTS
928 patients took part in the study, 895 from general rehabilitation facilities (GR) and 33 from early neurological rehabilitation (ENR). 65% of GR patients (ENR 100%) had been hospitalized in the previous 6 months, 29% (ENR 100%) of the patients had been admitted directly from a hospital, 22% (ENR 64%) had received antibiotic therapy in the last 3 months. Medical devices were rarely used in GR patients with 1% overall, but often in the ENR with 61% urinary catheters and 36% vascular catheters. 2.2% (ENR 33.3%) of GR patients were colonized with VRE and 6.7% (ENR 18.2%) with 3MRGN; one patient exhibited a 4MRGN (ENR 0).
DISCUSSION
Compared to our previous study, there were no significant changes in the patient characteristics. The VRE prevalence was low at 3.3%, the prevalence of 3MRGN was higher compared to 2014 (7.1% vs. 3.6%). Risk factors for VRE and 3MRGN colonization (significant increased odds ratio) were: history of hospital treatment and an increased need for care due to restricted mobility, incontinence and disorientation. In addition, previous antibiotic treatment and skin barrier injuries due to Medical devices or wounds were detected as further risk factors for VRE colonization.
