Multicenter Study
Improving healthcare worker adherence to the use of transmission-based precautions through application of human factors design: a prospective multi-centre study.
A key component of transmission-based precautions (TBPs) is the use of personal protective equipment (PPE) but healthcare worker (HCW) adherence remains suboptimal. A human factors-based intervention was implemented to improve adherence to TBPs including (i) improved signage, (ii) standardized placement of signage, (iii) introduction of a mask with integrated face shield, and (iv) improvement in PPE availability. Donning of the correct PPE by HCWs improved significantly (79.7 vs 56.4%; P < 0.001). This approach may be more effective than education alone, but further study is required to determine sustainability and subsequent impact on transmission of healthcare-associated infections.

Awareness of healthcare-associated infections (HAIs) and antimicrobial use in long-term care facilities (LTCFs) is increasing. In 2017, the third national point prevalence survey (PPS) was conducted in Italy as part of the third 'Healthcare-Associated Infections in European Long-Term Care Facilities' (HALT3) study. ⋯ The number of infection control and antimicrobial stewardship measures implemented was found to be considerably higher in this study compared with previous studies. This could lead to a reduction in the prevalence of HAIs, antimicrobial use and antimicrobial resistance. Further studies are needed to monitor these aspects.

Systematic cultures of drain tips or drainage fluids for the early detection of surgical site infections (SSIs) are controversial. To examine the association between the results of systematic drain tip or drainage fluid cultures and the occurrence of SSIs in clean or clean-contaminated surgery. Searches were performed in the PubMed, and Cat.inist databases for observational studies published before 31st March 2017. ⋯ The sensitivities were low (41%, 95% CI 12-73 for drain tip cultures and 37%, 95% CI 16-60 for drainage fluid cultures). The specificities were high (93%, 95% CI 88-96) for drain tip cultures and moderate (77%, 95% CI 54-94) for drainage fluid cultures. Systematic cultures of drain tips or drainage fluids appear not to be relevant, because their positive predictive values were low in the prediction of SSIs.

During high-incidence influenza seasons, a robust infection prevention and control policy is imperative to reduce nosocomial transmission of influenza. ⋯ Influenza POCT in an ED and patient cohorting on an influenza ward were associated with reduced nosocomial transmission of influenza and improved patient flow. A policy of retesting immunocompetent patients five days post-diagnosis could allow half of these patients to come out of respiratory isolation earlier.

Middle East respiratory syndrome coronavirus (MERS-CoV) is capable of causing acute respiratory illness. Laboratory-confirmed MERS-CoV cases may be asymptomatic, have mild disease, or have a life-threatening infection with a high case fatality rate. There are three patterns of transmission: sporadic community cases from presumed non-human exposure, family clusters arising from contact with an infected family index case, and healthcare-acquired infections among patients and from patients to healthcare workers. ⋯ Prompt recognition, isolation and management of suspected cases are key factors for prevention of the spread of MERS. Repeated assessments of infection control and monitoring of corrective measures contribute to changing the course of an outbreak. Limiting the number of contacts and hospital visits are also important factors to decrease the spread of infection.
