Pseudo-outbreak of Parengyodontium album related to contaminated saline used in specimen processing in the microbiology laboratory.

We report a cluster of 9 isolates of Parengyodontium album recovered from 4 patients who had surgical tissue specimens processed after dilution with a multiuse diluent saline solution. P album was also identified from a nonclinical sample on agar prepared with the same lot number of saline solution. Our epidemiological investigation revealed this to represent a pseudo-outbreak related to contaminated saline used to process specimens in the microbiology laboratory.

Epidemiology, Infection Prevention, Testing Data, and Clinical Outcomes of COVID-19 on Five Inpatient Psychiatric Units in a large Academic Medical Center.

Inpatient psychiatric facilities can face significant challenges in containing infectious outbreaks during the COVID-19 pandemic. The main objective of this study was to characterize the epidemiology, testing data, and containment protocols of COVID-19 in a large academic medical center during the height of the COVID-19 outbreak. A retrospective cohort analysis was conducted on hospitalized individuals on five inpatient psychiatric units from March 1st to July 8th, 2020. Demographic data collected include age, race, gender, ethnicity, diagnosis, and admission status (one or multiple admissions). In addition, a Gantt chart was used to assess outbreak data and timelines for one unit. Testing data was collected for patients admitted to inpatient psychiatric units, emergency room visits, and employees. 964 individuals were hospitalized psychiatrically. The study population included ethnically diverse patients with various mental illnesses. We also describe infection prevention strategies, screening, and triage protocols utilized to safely continue patient flow during and beyond the study period with a low patient and employee infection rate. In summary, our study suggests that early implementation of triage, screening, extensive testing, and unit-specific interventions can help prevent and contain the spread of COVID-19 in inpatient psychiatric units and help facilitate safe delivery of care during a pandemic.

Oxygen nipple and nut (Christmas tree) adaptor contamination rates and decontamination with disinfecting wipes.

OBJECTIVE: Different manufacturers recommend different levels of disinfection for oxygen nipple and nut adaptors, also known as Christmas-tree adaptors (CTAs). We aimed to determine the bacterial contamination rates of CTAs before and after clinical use and whether disinfection wipes effectively eliminate bacteria from CTAs. METHODS: CTAs were swabbed for bacteria directly from the shipment box or after use in a medical intensive care unit to determine levels of contamination. CTAs were also inoculated in the laboratory with a variety of bacteria and disinfected with either 0.5% hydrogen peroxide (Oxivir 1) or 0.25% tetra-ammonium chloride with 44.50% isopropyl alcohol (Super Sani-Cloth), and the effectiveness of each wipe was determined by comparing the bacterial recovery before and after disinfection. RESULTS: CTAs exhibit low levels of bacterial burden before and after clinical use. Both disinfecting wipes were effective at removing bacteria from the CTAs. CONCLUSIONS: Low-level disinfection of CTAs is appropriate prior to redeployment in the clinical setting.
