RESUMEN
BACKGROUND: Multi-resistant bacteria (MRB) are an emerging problem. Early identification of patients colonized with MRB is mandatory to avoid in-hospital transmission and to target antibiotic treatment. Since most patients pass through specialized emergency departments (EDs), these departments are crucial in early identification. The Danish National Board of Health (DNBH) has developed exposure-based targeted screening tools to identify and isolate carriers of meticillin-resistant Staphylococcus aureus (MRSA) and carbapenemase-producing Enterobacteriaceae (CPE). AIM: To assess the national screening tools for detection of MRSA and CPE carriage in a cohort of acute patients. The objectives were to investigate: (i) if the colonized patients were detected; and (ii) if the colonized patients were isolated. METHODS: This was a multi-centre cross-sectional survey of adults visiting EDs. The patients answered the DNBH questions, and swabs were taken from the nose, throat and rectum. The collected samples were examined for MRSA and CPE. Screening performances were calculated. FINDINGS: Of the 5117 included patients, 16 were colonized with MRSA and four were colonized with CPE. The MRSA screening tool had sensitivity of 50% [95% confidence interval (CI) 25-75%] for carrier detection and 25% (95% CI 7-52%) for carrier isolation. The CPE screening tool had sensitivity of 25% (95% CI 1-81%) and none of the CPE carriers were isolated. CONCLUSION: The national screening tools were of limited use as the majority of MRSA and CPE carriers passed unidentified through the EDs, and many patients were isolated unnecessarily.

We investigated whether initiating a clinical pathway, that incorporated the use of an alcohol withdrawal assessment scale, would decrease length of stay (LOS) for and/or amount of benzodiazepine prescribed during uncomplicated alcohol detoxification. We retrospectively reviewed alcohol detoxification admissions on an inpatient unit: 66 admissions before, 56 after, and 75 admissions 1-year after initiation of the pathway. Admissions were grouped into completers and non-completers. Comparison of group means before and after pathway implementation demonstrated a significant decrease in LOS for completers of the detoxification service from 7.35 to 4.77 days, and from 6.67 to 4.31 days for all admissions. Similarly, total benzodiazepine exposure decreased to a third of the mg amount given per admission prior to the pathway. There were no increases in the "irregular" discharge rate or complication rate. These findings suggest that a clinical pathway, with an incorporated withdrawal assessment scale, can decrease LOS and benzodiazepine prescribing on an alcohol detoxification unit.
