Implementation and adaptation of the protocols according to local requirements and guidelines will ameliorate the quality of services and population's health status. Finally, enhancement of current practices will prepare health systems for future crisis. 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. 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, hosatment and an increased need for care due to restricted mobility, incontinence and disorientation. In addition, previous antibiotic treatment and skin barrier injuries due to or wounds were detected as further risk factors for VRE colonization. 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
