Control of a Clonal Outbreak of Multidrug-Resistant Acinetobacter baumannii in a Hospital of the Basque Country after the Introduction of Environmental Cleaning Led by the Systematic Sampling from Environmental Objects

Investigation of Acinetobacter baumannii Outbreak in a Burn Unit Revealed a Surprising Environmental Source

We describe an outbreak of Acinetobacter baumannii in a 15-bed regional burn unit in an academic tertiary care medical center, and the investigations and control measures used to halt the outbreak are described. Nine cases of A. baumannii were reported in our burn unit in a one-year period, which was higher than our expected number of two-three cases per year. Our burn unit director requested an outbreak investigation, and our hospital's infection control department investigated thoroughly and found a source for that outbreak, which was never reported as a source in the previous literature. We identified table fans as the source of this outbreak. We then developed a strict fan policy, and after implementation of the policy, and terminal cleaning of rooms, only two cases per year of A. baumannii were reported in the next three-year period. We concluded that the table fans were colonized with A. baumannii and since they were used interchangeably in all patient rooms, caused this outbreak. There are no specific joint commission guidelines for the use of fans in hospitals. While fans can be used for the comfort of the patient, we should be cautious not to spread infections.

Unveiling the unknown: first comprehensive assessment of the knowledge, attitudes and practices of hospital cleaning services staff regarding COVID-19 in Lebanon during the pandemic

BACKGROUND

Hospital cleaners are the unsung heroes in the fight against the COVID-19 pandemic. This study aimed to assess the knowledge, attitudes, and practices (KAP) of hospital cleaners towards COVID-19 and determine factors associated with good practices.

METHODS

A cross-sectional study was conducted in Lebanon between the 1st and 14th November 2020. Using a snowball sampling technique, data were collected through an online survey that was sent to governmental and private hospitals. The questionnaire consisted of socio-demographic characteristics and KAP of hospital cleaners towards COVID-19. Descriptive statistics and logistic regression analysis were performed.

RESULTS

A total of 453 cleaners completed the survey, of whom 54.3% were females. Most participants had a good level of COVID-19 knowledge (98%) and good preventive practices (89.7%). Regarding attitude, 90.7% had a positive attitude toward health facilities, 78.8% toward cleaning and disinfection, and 73.5% toward health authorities. Sociodemographic characteristics, including younger age, higher levels of education, working in private hospitals, and having more than 3 years of experience, were positively associated with good preventive practices. Our results also showed that participants who had good knowledge about COVID-19, COVID-19 prevention and treatment, cleaning and disinfection processes, and COVID-19 risk factors had a higher likelihood of positive preventive practices. Finally, a positive attitude toward health facilities, health authorities, and cleaning and disinfection was positively associated with good practices.

CONCLUSION

The surveyed cleaners have a high level of knowledge and expressed positive attitudes toward health facilities and health authorities, as well as good preventive practices. Understanding the determinants of cleaning performance is critical in tailoring interventions to improve hospital cleaning.

Patient Safety Related to Microbiological Contamination of the Environment of a Multi-Profile Clinical Hospital

Nosocomial infections pose a serious burden for hospitals, patients, and the entire society. The aim of the study was to assess the microbiological cleanliness of the hospital environment through quantitative and qualitative analysis of microbiological contamination of air and surfaces in inpatient treatment facilities, based on the example of a large clinical hospital in Poland. Data were collected between 2012 and 2018 in premises of a large teaching hospital in Gdansk using the sedimentation method and the impact method using the Aerideal apparatus (Biomerieux). In the analyzed clinical center, the microbiological cleanliness tests in most of the hospital rooms in the analyzed period showed an acceptable number of saprophytic microorganisms. Of all the tested samples, 1159 (21.8%) were positive, indicating the presence of microorganisms in the tested sample. Species potentially pathogenic for hospital patients were identified, constituting 20.8% of all positive samples (4.6% of all samples). Significantly higher proportion of microorganisms potentially dangerous to patients were isolated from sanitary facilities. Due to the potentially pathogenic microorganisms detected in the tested samples, the authors suggest that in the analyzed hospital, the areas requiring a specific level of microbiological purity should be designated and described, with [specifically] defined cleaning and disinfection protocols.

Recommendations for detection and rapid management of carbapenemase-producing Enterobacterales outbreaks

There is large heterogeneity in approaches to tackling nosocomial outbreaks caused by carbapenemase-producing Enterobacterales (CPE), however there is limited guidance on how to approach their management. Rapid and robust infection prevention and control interventions can be effective in preventing and reducing the impact of outbreaks in healthcare environments. We present a stepwise approach to aspects of CPE outbreak management, including the development of an action plan, engagement and communication with key stakeholders, developing a dynamic risk assessment, and staff education. These can provide a blueprint for organisations to create templates and checklists to inform their own outbreak response.

Challenges in diagnosing community-acquired carbapenem-susceptible Acinetobacter baumannii enterogenic sepsis: A case report

INTRODUCTION

Community-acquired (CA) carbapenem-susceptible Acinetobacter baumannii (CSAB) enterogenic sepsis is very rare but has a high mortality. Although CA A. baumannii bloodstream infections have been known to develop from respiratory tract, urinary tract, and intravenous device-related infections, CA A. baumannii bloodstream infections from the gastrointestinal tract have not yet been reported.

PATIENT CONCERNS

A 73-year-old male with the chief presentation of gastrointestinal symptoms was initially diagnosed with acute gastroenteritis and showed poor clinical response to empirical antibiotic therapy.

DIAGNOSES

The diagnosis of CSAB enterogenic sepsis was established based on results of blood culture, elevated serum procalcitonin level, and specific hemodynamic changes related to septic shock.

INTERVENTIONS

The patient initially received empirical antibiotic treatment (cefodizime 2.0 q12 hours plus moxifloxacin 0.4 qd); then, treatment was changed to the conventional dose of carbapenem (imipenem 0.5 q6 hour).

OUTCOMES

Finally, CSAB was eliminated from the bloodstream, and the patient was discharged.

LESSONS

Although severe, CA CSAB enterogenic sepsis is often misdiagnosed because of its clinical rarity. Early diagnosis and appropriate initial empirical antibiotic therapy are crucial for treating such cases.

Controlling hospital-acquired infection: focus on the role of the environment and new technologies for decontamination

There is increasing interest in the role of cleaning for managing hospital-acquired infections (HAI). Pathogens such as vancomycin-resistant enterococci (VRE), methicillin-resistant Staphylococcus aureus (MRSA), multiresistant Gram-negative bacilli, norovirus, and Clostridium difficile persist in the health care environment for days. Both detergent- and disinfectant-based cleaning can help control these pathogens, although difficulties with measuring cleanliness have compromised the quality of published evidence. Traditional cleaning methods are notoriously inefficient for decontamination, and new approaches have been proposed, including disinfectants, steam, automated dispersal systems, and antimicrobial surfaces. These methods are difficult to evaluate for cost-effectiveness because environmental data are not usually modeled against patient outcome. Recent studies have reported the value of physically removing soil using detergent, compared with more expensive (and toxic) disinfectants. Simple cleaning methods should be evaluated against nonmanual disinfection using standardized sampling and surveillance. Given worldwide concern over escalating antimicrobial resistance, it is clear that more studies on health care decontamination are required. Cleaning schedules should be adapted to reflect clinical risk, location, type of site, and hand touch frequency and should be evaluated for cost versus benefit for both routine and outbreak situations. Forthcoming evidence on the role of antimicrobial surfaces could supplement infection prevention strategies for health care environments, including those targeting multidrug-resistant pathogens.

Control of an Outbreak ofAcinetobacter baumanniiin Burn Unit in a Tertiary Care Hospital of North India

Acinetobacterinfection is increasing in hospitals and now it is considered as a global threat, as it can be easily transmitted and remain viable in the hospital environment for a long time due to its multidrug-resistant status, resistance to desiccation, and tendency to adhere to inanimate surfaces. Outbreaks caused by multidrug-resistantAcinetobacter baumannii(MDRAB) are difficult to control and have substantial morbidity and mortality, especially in vulnerable host. Here we are describing an outbreak of multidrug-resistantAcinetobacter baumanniiin burn unit of a tertiary care hospital in India followed by its investigation and infection control measures taken to curtail the outbreak. Outbreak investigation and environmental sampling are the key factors which help in deciding the infection control strategies for control of outbreak. Implementation of contact precautions, hand hygiene, personnel protective equipment, environmental disinfection, isolation of patients, and training of health care workers are effective measures to control the outbreak of MDRAB in burn unit.
