Concern about the health of people who traveled onboard was raised during the COVID-19 outbreak on the Diamond Princess cruise ship. The ship’s narrow space offers an environment conducive to the virus’s spread. Close contact isolation remains one of the most critical current measures to stop the virus’s rapid spread. Contacts can be identified efficiently by detecting intelligent devices nearby. The smartphone’s Bluetooth RSSI signal is essential data for proximity detection. This paper analyzes Bluetooth RSSI signals available to the public and compares RSSI signals in two distinct poses: standing and sitting. These features can improve accuracy and provide an essential basis for creating algorithms for proximity detection. This allows for improved accuracy in identifying close contacts and can help ships sustainably manage persons onboard in the post-epidemic era.

Absract Background To describe the course and intervention of an hospital-wide IMI-Producing Enterobacter ludwigii outbreak. Methods This was an outbreak interventional study, done at a tertiary care center in Tel-Aviv, Israel. Data was collected on the course of the outbreak and the demographic and clinical characteristics of all patients involved in the outbreak. The intervention measures included patients’ cohorting, contact isolation precautions, environmental cleaning and screening of contacts. The molecular features and phylogeny of outbreak-related isolates were studied by whole-genome based analysis. Results The outbreak included 34 patients that were colonized by IMI-Producing E. ludwigii and were identified in 24 wards throughout the hospital. Colonization was identified in the first 72 h of admission in 13/34 patients (38.2%). Most patients (91.2%) were admitted from home and had relatively low level of comorbidities. The majority of them (88%) had no recent use of invasive catheters and none had previous carriage of other multi-drug resistant bacteria. All available isolates harbored the blaIMI-17 allele and belonged to Sequence-Type 385. With the exception of two isolates, all isolates were closely related with less than a 20-SNP difference between them. Conclusions This outbreak had most likely originated in the community and subsequently disseminated inside our institution. More studies are required in order to elucidate the epidemiology of IMI-Producing E. ludwigii and the possible role of environmental sources in its dissemination.

Abstract Background: Molecular syndromic panels can rapidly detect common pathogens responsible for acute gastroenteritis in hospitalized patients. Their impact on both patient and healthcare system outcomes is uncertain compared to conventional stool testing. This randomized trial evaluates the impact of molecular testing on in-hospital resource utilization compared to conventional stool testing.Methods: Hospitalized patients with acute diarrheal illness were randomized 1:1 to either conventional or molecular stool testing with the BioFire FilmArray gastrointestinal panel (FGP). The primary outcome was duration of contact isolation, and secondary outcomes included other in-hospital resource utilization such as diagnostic imaging and antimicrobial use. Results: A total of 156 patients were randomized. Randomization resulted in a balanced allocation of patients across all 3 age strata (<18, 18-69, ≥70 years old). The proportion of positive stools was 20.5% vs 29.5% in the control and FGP groups, respectively (p=0.196). The median duration of contact isolation was 51 hours (interquartile range (iqr) 66) and 69 hours (iqr 81) in the conventional and FGP groups, respectively (p=0.0513). There were no significant differences in other in-hospital resource utilization between groups. Conclusions: There were no differences in in-hospital resource utilization observed between FGP and conventional stool testing groups. Trials Registration: ClinicalTrials.gov NCT04189874

Objective: To determine the superbug infection in a burn centre, its impact on mortality/morbidity and to review all preventive/therapeutic steps taken to fight this menace. Study Design: Retrospective cross sectional study. Place and Duration of Study: Department of Burns & Plastic Surgery, Army Burn Centre, Combined Military Hospital Kharian, from Oct 2018 to Sep 2019. Methodology: A detailed retrospective audit of departmental data was carried out. Parameters like direct admission vs transferred patient, percentage of burns (Total Burn Surface Area-TBSA%), records of all burns related deaths and all culture/sensitivity reports were analysed using SPSS-20. As a standard practice in our unit blood, tracheal secretions and pus culture specimens of all patients are collected at the time of admission and then periodically fresh samples are taken every week or earlier when-ever required. Results: Out of 515 patients, 283 (54.95%) were children under the age of 12 years. The overall survival rate improved by 13.43% as compared to last year. Out of 584 bacteriology reports 396 (67.81%) were positive and 188 (32.19%) were negative. On culture 508 organisms were isolated, majority of which were Carbapenem Resistant Pseudomonas, Acinetobacter, Enterobacteriaceae and Methicillin resistant staphylococcus aureus. Conclusion: Multi drug resistant superbug infection is a worldwide menace. The best clinical practices, strict contact isolation, enhanced environmental cleaning and judicious use of appropriate antibiotics are the main strategies in this war. Need for newer more effective antibiotics cannot be overemphasized.

BACKGROUND Providencia rettgeri is a rare cause of nosocomial infection in humans. These organisms are capable of biofilm production and are intrinsically resistant to commonly used antibiotics, leading to high rates of morbidity and mortality. P. rettgeri may very rarely cause postneurosurgical infection. OBSERVATIONS In this report, the authors describe two patients in whom P. rettgeri infection complicated the postoperative course. Both the patients underwent craniotomy at approximately the same time under similar environments. The organism isolated was resistant to most of the commonly used antibiotics, and therapy tailored to the results of susceptibility testing led to resolution of infection in both cases. LESSONS P. rettgeri is a rare cause of postneurosurgical nosocomial infection. Timely identification and early tailoring of antibiotic therapy based on susceptibility testing is the key to treatment. Every effort should be made to identify the source of infection and rectify it so that mortality, morbidity, and financial burden are reduced. Contact isolation and use of sterile gloves after each patient contact are effective in preventing its spread, as in most cases of nosocomial infection.

Due to the COVID-19 pandemic, many older adults have experienced contact isolation in a hospital setting which leads to separation from relatives, loss of freedom, and uncertainty regarding disease status. The objective of this study was to explore how older adults (55+) cope with contact isolation in a hospital setting during the COVID-19 pandemic in order to improve their physical and psychological wellbeing. The realist evaluation approach was used to formulate initial program theories on coping strategies used by (older) adults in an isolation setting. Twenty-one semi-structured interviews with older patients (n = 21) were analysed. This study revealed that both emotion-focused coping strategies as well as problem-focused coping strategies were used by older adults during contact isolation. The study also uncovered some new specific coping strategies. The results have useful implications for hospital staff seeking to improve the wellbeing of older adults in contact isolation in hospitals. Problem-focused coping strategies could be stimulated through staff performing care in a person-centred way. Trust in staff, as part of emotion-focused coping strategies, could be stimulated by improving the relationship between patients and staff.

Clostridioides difficile infection (CDI) is one of the leading causes of hospital–onset infections. Clinically distinguishing true CDI versus colonization with C. difficile is challenging and often requires reliable and rapid molecular testing methods. At our academic center, we implemented a 2-step testing algorithm to help identify true CDI cases. The University of Mississippi Medical Center is a 700+ bed academic facility located in Jackson, Mississippi. Hospital-onset (HO) CDI was defined based on NHSN Laboratory Identified (LabID) event as the last positive C. difficile test result performed on a specimen using a multistep testing algorithm collected >3 calendar days after admission to the facility. HO-CDI data were collected from all inpatient units except the NICU and newborn nursery. HO-CDI outcomes were assessed based on standardized infection ratio (SIR) data. In May 2020, we implemented a 2-step testing algorithm (Figure 1). All patients with diarrhea underwent C. difficile PCR testing. Those with positive C. difficile PCR test were reflexed to undergo enzyme immunoassay (EIA) glutamate dehydrogenase antigen (Ag) testing and toxin A and B testing. The final results were reported as colonization (C. difficile PCR+/EIA Ag+/Toxin A/B−) or true CDI case (C. difficile PCR+/EIA +/Toxin A/B +) or negative (C. difficile PCR−). All patients with colonization or true infection were placed under contact isolation precautions until diarrhea resolution for 48 hours. During the preintervention period (October 2019–April 2020), 25 HO-CDI cases were reported compared to 8 cases in the postintervention period (June 2020–December 2020). A reduction in CDI SIR occurred in the postintervention period (Q3 2020–Q4 2020, SIR 0.265) compared to preintervention period (Q4 2019–Q1 2020, SIR 0.338) (Figure 2). We successfully reduced our NHSN HO-CDI SIR below the national average after implementing a 2-step testing algorithm for CDI. The 2-step testing algorithm was useful for antimicrobial stewardship to guide appropriate CDI treatment for true cases and for infection prevention to continue isolation of infected and colonized cases to reduce the spread of C. difficile spores.Funding: NoDisclosures: None

Abstract Background Patient information provision about isolation measures is often not standardised. Moreover, it is unclear what information patients and informal caregivers need to optimize their knowledge and actual experience of contact isolation. We explored opportunities for improving the experience of patients in contact isolation from a human-centred design perspective.Methods We used patient journey mapping and created patient personas based on observations and interviews with patients and health care workers from a haematology, surgery and acute admission ward of a Dutch university hospital.Results Patients differed in their experience of contact isolation; three personas were identified. The first liked being in contact isolation, the second had to get used to the measures, the third experienced contact isolation as overwhelming. Patients experienced a lack in structured and tailored information about contact isolation. Nurses confirmed this lack of structure and reported their need for clear instructions on how to inform patients and their informal caregivers and what information to provide at which point in time. By using a human-centred design approach, we created a first draft of an interactive information path for patients, informal care givers and health care workers.Conclusion To improve the patient experience in contact isolation, patient information could be structured throughout the patient journey. Information should emphasize the shared responsibility of isolation between patient, health care workers and informal caregivers.

Objective: to build and validate the content and appearance of the booklet on prevention and control of contact-borne infections. Methods: methodological study, developed from the validation of an educational booklet by expert judges and by the target audience. The validation was performed by seventeen judges from different Brazilian regions and seven companions. The agreement index between the evaluators was calculated, with a minimum of 80.0% being necessary to guarantee the validation of the material. Results: most of the items obtained agreement rates above the recommended. The changes were made according to the judges’ suggestions, giving rise to the second version of the booklet, which was submitted to the appearance validation by the target audience, culminating in changes in the cover and language. Conclusion: the booklet was considered valid by specialists and by the target audience, and could be technology used for companions of patients kept in contact isolation.
