Sharps and needle-stick injuries among medical residents and healthcare professional students: pattern and reporting in Italy-a cross-sectional analytical study.

OBJECTIVES: Healthcare workers, in the course of their professional activity, are potentially exposed to chemical, physical and above all biological risks. The aims of our study were to investigate the extent and distribution of needle-stick and sharp injuries (NSIs) in healthcare students, the behaviours and circumstances most frequently associated with NSIs, the frequency of NSI reporting and the adherence to the post-exposure protocols. METHODS: This study involved, through an interviewer-administered structured questionnaire, undergraduate and postgraduate students attending postgraduate medical schools and healthcare professional schools who underwent occupational health visits between January 2015 and July 2018. RESULTS: Of the 642 students that participated in the study, 95 (14.8%) sustained an NSI during the traineeship and, of these, 59 (62.1%) reported the NSI to the occupational health service. NSIs were significantly more frequent in older subjects (χ²=9.853, p=0.020) and, among medical residents, in surgical residents (χ²=31.260, p<0.0001); moreover, occurrence of NSIs increased with increasing duration of traineeship (t=-2.051, p=0.041). Reporting of NSIs significantly increased with increasing age (χ²=12.543, p=0.006), with medical residents significantly under-reporting NSIs compared with undergraduate healthcare professional students (χ²=10.718, p=0.001) and among medical residents, those attending critical care units had the highest under-reporting (χ²=7.323, p=0.026). CONCLUSIONS: The study showed remarkable under-reporting, as well as a lack of preparedness of students for NSI preventive and post-exposure effective measures. Our findings underline that healthcare student education should be reinforced to ensure that safe practices are carried out when needles and sharps are involved, as well as stressing the importance of NSI reporting and adherence to post-exposure prophylaxis protocols.

Effect of an enhanced public health contact tracing intervention on the secondary transmission of SARS-CoV-2 in educational settings: The four-way decomposition analysis.

Background: The aim of our study was to test the hypothesis that the community contact tracing strategy of testing contacts in households immediately instead of at the end of quarantine had an impact on the transmission of SARS-CoV-2 in schools in Reggio Emilia Province. Methods: We analysed surveillance data on notification of COVID-19 cases in schools between 1 September 2020 and 4 April 2021. We have applied a mediation analysis that allows for interaction between the intervention (before/after period) and the mediator. Results: Median tracing delay decreased from 7 to 3.1 days and the percentage of the known infection source increased from 34-54.8% (incident rate ratio-IRR 1.61 1.40-1.86). Implementation of prompt contact tracing was associated with a 10% decrease in the number of secondary cases (excess relative risk -0.1 95% CI -0.35-0.15). Knowing the source of infection of the index case led to a decrease in secondary transmission (IRR 0.75 95% CI 0.63-0.91) while the decrease in tracing delay was associated with decreased risk of secondary cases (1/IRR 0.97 95% CI 0.94-1.01 per one day of delay). The direct effect of the intervention accounted for the 29% decrease in the number of secondary cases (excess relative risk -0.29 95%-0.61 to 0.03). Conclusions: Prompt contact testing in the community reduces the time of contact tracing and increases the ability to identify the source of infection in school outbreaks. Although there are strong reasons for thinking it is a causal link, observed differences can be also due to differences in the force of infection and to other control measures put in place. Funding: This project was carried out with the technical and financial support of the Italian Ministry of Health - CCM 2020 and Ricerca Corrente Annual Program 2023.

Surveillance, contact tracing and characteristics of SARS-CoV-2 transmission in educational settings in Northern Italy, September 2020 to April 2021.

BACKGROUND: The role of school contacts in the spread of the virus and the effectiveness of school closures in controlling the epidemic is still debated. We aimed to quantify the risk of transmission of SARS-CoV-2 in the school setting by type of school, characteristics of the index case and calendar period in the Province of Reggio Emilia (RE), Italy. The secondary aim was to estimate the speed of implementation of contact tracing. METHODS: A population-based analysis of surveillance data on all COVID-19 cases occurring in RE, Italy, from 1 September 2020, to 4 April 2021, for which a school contact and/or exposure was suspected. An indicator of the delay in contact tracing was calculated as the time elapsed since the index case was determined to be positive and the date on which the swab test for classmates was scheduled (or most were scheduled). RESULTS: Overall, 30,184 and 13,608 contacts among classmates and teachers/staff, respectively, were identified and were recommended for testing, and 43,214 (98.7%) underwent the test. Secondary transmission occurred in about 40% of the investigated classes, and the overall secondary case attack rate was 4%. This rate was slightly higher when the index case was a teacher but with almost no differences by type of school, and was stable during the study period. Speed of implementation of contact tracing increased during the study period, with the time from index case identification to testing of contacts being reduced from seven to three days. The ability to identify the possible source of infection in the index case also increased. CONCLUSIONS: Despite the spread of the Alpha variant during the study period in RE, the secondary case attack rate remained stable from school reopening in September 2020 until the beginning of April 2021.

Antimicrobial Resistance in Pathogens Isolated from Blood Cultures: A Two-Year Multicenter Hospital Surveillance Study in Italy.

BACKGROUND: Antimicrobial resistance (AMR) is one of the most concerning issues in medicine today. The objectives of this study were to investigate the AMR distribution of the blood-borne pathogens isolated over a two-year period in an Italian region. METHODS: A retrospective electronic record review of laboratory-confirmed bloodstream infections (BSIs) was done, and data from three major diagnostic laboratories were used. Twelve invasive clinically important bacteria species were included in the sample. RESULTS: During the study period, 1228 positive BSIs were collected. The most common pathogens were Coagulase-negative Staphylococcus (CoNS) (29.7%), Staphylococcus aureus (19.1%) and Escherichia coli (15.9%). With regard to the AMR pattern, 31.7% of CoNS and 28.1% of Staphylococcus aureus were oxacillin-resistant, and almost half of the Enterococci showed resistance to high-level gentamicin. Among Gram-negative species, 11.7% of Escherichia coli and 39.5% of Klebsiella pneumoniae were carbapenem-resistant. Among the non-fermentative Gram-negative bacteria, the most frequently combined AMR pattern was aminoglycosides and fluoroquinolones (48.4% in A. baumannii and 14.6% in P. aeruginosa). CONCLUSION: The results display an alarming prevalence of AMR among hospital isolated pathogens, consistently higher than the European average. Information from surveillance systems to better characterize the trend in the incidence of AMR at local and national levels is needed.

Comparative effectiveness of breathing exercises in patients with chronic obstructive pulmonary disease.

BACKGROUND AND PURPOSE: This study aims to determine the best choice of breathing exercises (BE) for patients with chronic obstructive pulmonary disease (COPD) via a network meta-analysis. METHODS: We searched randomized controlled trials (RCTs) of adults with COPD investigating any BEs in MEDLINE, Embase, Cochrane Library, and ClinicalTrials.gov databases. The effects of comparative treatment on the St. George Respiratory Questionnaire as the outcome were analysed and ranked according to a surface under the cumulative classification curve (SUCRA) analysis. RESULTS: The network meta-analysis included six RCTs involving 280 patients with four intervention groups, comprising control, diaphragmatic breathing training (DBT), yoga, and singing course. Performing SUCRA, we reported that yoga is 75% likely to be the best treatment available as DBT with 66%, instead of 35% for singing and 21% for control. CONCLUSION: DBT and yoga seem to be the best choices for breathing exercises in people with COPD.
