Patient Safety and Surgery: the Experience of the Lombardy Region. A Project on External Evaluation of Best Practices Implementation.

Meta-analysis studies published over the past 20 years document that approximately 10 -14 % of hospitalised patients have an adverse event in Surgery and at least half of these adverse events are considered preventable using the current standards of care. In order to improve the safety of surgical patients and increasing adherence to current standard of care in surgery, including communication within the team and teamwork, in 2007 the WHO launched the campaign "Safe Surgery Saves Lives". The WHO has also built a checklist for safety in the operating room containing 19 item in support of the operating team. The Ministry of Health in 2009 has taken the instruments produced by WHO in the "Guide to Safety in the operating room: Recommendations and Checklist". Studies conducted in industrialized countries report a strong heterogeneity in compliance to the check list for the surgical safety, with a range of between 38% and 96%. The aim of this project was to adopt the methodology of the external "peer review" to improve quality and patient safety applied to the surgical process and assess the degree of implementation of good practice in the operating room, both in public and private structures. Between 2015 and 2018 we have carried out 16 external evaluation visits. These visits included a first plenary session followed by the inspection of the operating theaters identified and a second plenary session. Several factors emerged during the visits; these factors represent both the strengths and criticalities of the organizations. The creation of a team of experts, coordinated by the Lombardy Region with the role of leadership, using the "peer review" methodology, is the leverage to promote among operators the growth of awareness of the usefulness of the tools.

Spike-specific humoral and cellular immune responses after COVID-19 mRNA vaccination in patients with cirrhosis: A prospective single center study.

BACKGROUND AND AIMS: COVID-19 mRNA vaccines were approved to prevent severe forms of the disease, but their immunogenicity and safety in cirrhosis is poorly known. METHOD: In this prospective single-center study enrolling patients with cirrhosis undergoing COVID-19 vaccination (BNT162b2 and mRNA-1273), we assessed humoral and cellular responses vs healthy controls, the incidence of breakthrough infections and adverse events (AEs). Antibodies against spike- and nucleocapsid-protein (anti-S and anti-N) and Spike-specific T-cells responses were quantified at baseline, 21 days after the first and second doses and during follow-up. RESULTS: 182 cirrhotics (85% SARS-CoV-2-naïve) and 38 controls were enrolled. After 2 doses of vaccine, anti-S titres were significantly lower in cirrhotics vs controls [1,751 (0.4-25,000) U/mL vs 4,523 (259-25,000) U/mL, p=0.012] and in SARS-CoV-2-naïve vs previously infected cirrhotics [999 (0.4-17,329) U/mL vs 7,500 (12.5-25,000) U/mL, (p<0.001)]. T-cell responses in cirrhotics were similar to controls, although with different kinetics. In SARS-CoV-2-naïve cirrhotics, HCC, Child-Pugh B/C and BNT162b2 were independent predictors of low response. Neither unexpected nor severe AEs emerged. During follow-up, 2% turned SARS-CoV-2 positive, all asymptomatic. CONCLUSION: Humoral response to COVID-19 vaccines appeared suboptimal in patients with cirrhosis, particularly in SARS-CoV-2-naïve decompensated cirrhotics, although cellular response appeared preserved, and low breakthrough infections rate was registered.

Legionnaires' disease contracted from patient workplace: First report of a severe case of coinfection with varicella-zoster virus.

A middle-aged immunocompetent woman was diagnosed and treated for a severe pulmonary human herpesvirus 3 infection. During the treatment, an infection from Legionella pneumophila serogroup 1 was also diagnosed. This coinfection threatened the life of the patient and led to serious permanent sequelae. This report highlights the importance of preventing Legionella environmental contamination, suspecting Legionella coinfection in patients with viral pneumonia, and vaccinating susceptible adults against chickenpox.

Violence and unsafety in a major Italian hospital: experience and perceptions of health care workers.

UNLABELLED: Workers' experience of violence and perceived unsafety can have a profound impact on job satisfaction, job performance, and workers' decision to leave. OBJECTIVES: The aim of the study was to assess the prevalence of physical and non-physical violence among hospital workers, explore the complaints and reactions of victims, assess the relationship between violence and psychosocial/work factors and analyze the levels of perceived unsafety. METHODS: A cross-sectional study was conducted, via a structured self-administered questionnaire given to all the employees of a major hospital in Italy. Cronbach's alpha coefficient was used to assess the internal consistency of the questionnaire. A logistic regression model was used for data analysis. RESULTS: 903 questionnaires out of 1853 (48.7%) were correctly returned; 11.5% had experience of physical violence and 40.2% had been victims of verbal violence in the previous 12 months. The most common consequences were fear, anger, frustration, and anxiety. Verbal violence was influenced by age, role, department, night/holiday shift work and experience in the current ward. Experiences of physical violence were related to gender, role, and department; 469 responders (51.9%) reported feelings of unsafety, which were related to their professional role, department, shift work, experience of physical or psychological violence, having seen episodes of violence and having received specific training. CONCLUSIONS: Our findings suggest that several factors are associated with workplace violence in health care settings and some of these also influenced the levels of perceived unsafety.

Use of DNA arrays for the analysis of outbreak-related strains of Listeria monocytogenes.

We evaluated the discriminative power and usefulness of the DNA array technology as compared to DNA macrorestriction pattern analysis for monitoring epidemiologically related clusters of Listeria monocytogenes strains that differ slightly in DNA macrorestriction patterns. We show that this approach allows clarifying the genetic basis of the pattern variations. In the reported outbreak, the differences were due to phage excision, showing the power of this technique in epidemiological studies.
