Objective: A troublesome implication of the COVID-19 pandemic has been an increased incidence of antimicrobial resistance. Implementation of containment measures, surveillance and monitoring of multiresistant microorganisms and/or alert organisms (MDROs_AL) should be strengthened. Here, we present the results of our observational study in which the isolation trend of MDROs_AL was compared over several quarters before and during the SARS-CoV-2 pandemic (2019-2020). Results: Although in our hospital the number of hospital admissions decreased significantly during the SARS-CoV-2 pandemic (due to the conversion of our hospital to a COVID hospital), the incidence rate of MDRO_AL infection increased from 18.0–34.6. (incidence rate) Among the MDROs_AL, A. baumannii, carbapenem-resistant enterobacteria, staphylococci/streptococci-MLSB, intermediate/glycopeptide-resistant coagulase-negative staphylococci and vancomycin-resistant enterococci were the most represented.

The COVID-19 pandemic has severely affected health systems worldwide and raised the issue of vaccine hesitancy. In 2022, the World Health Organization reported an outbreak of measles infection among people over 20 years of age in the European Region. Previous studies found low rates of measles immunization among Italian healthcare workers (HCWs) and medical students. Vaccine hesitancy is a relevant cause of low immunization rate among HCWs and the general population. We aim to evaluate the measles vaccine uptake among medical students of a large teaching hospital, compared to the pre-pandemic period. This is a retrospective observational study, that evaluated the immune status and the vaccine acceptance rate for measles in medical students at the University of Tor Vergata, Rome, who underwent occupational health surveillance from 1 January to 1 December 2022. We also compared the data with the results of a pre-pandemic survey conducted in 2018. Vaccine uptake among unprotected medical students was 59.5%. The data showed no significant difference in vaccine uptake compared with the pre-COVID-19 period. Conversely, the rate of serologically immune subjects to measles increased from 89.66% in 2018 to 97.45% in 2022 as a result of the recent mandatory vaccination policy. Despite efforts to tackle vaccine hesitancy during the COVID-19 pandemic, measles vaccine uptake is still low among young adults starting their medical training, and their compliance with free workplace vaccination offers is suboptimal. Occupational health services should raise awareness among workers and work together to implement strategies to achieve comprehensive measles vaccination coverage among occupational health workers.

Healthcare workers (HCWs) have an increased risk to be exposed to infectious diseases compared to the general population. For this reason, according to the National Immunization and Prevention Plan, all HCWs should have demonstrable evidence of immunity to measles, mumps, rubella, varicella and Hepatitis B. Earlier studies have already shown that a large percentage of Italian operators lacked immune protection for one or more of those pathogens. The aim of this study was to evaluate the immunization status for vaccine-preventable diseases of HCWs in a large Italian teaching hospital. We retrospectively evaluated clinical records and serological data of HCWs who followed the occupational health surveillance program between January 1 and December 31 2019. We reviewed the clinical records of 1,017 HCWs: 393 males and 624 females with a median age of 35.69 y (range: 19–67). Protective IgG antibody values were documented in the 88.0%, 75.7%, 90.3%, 87.4% and 85.7% of the HCWs screened, respectively, against measles, mumps, rubella, varicella and Hepatitis B. Age was significantly related to serological protection against measles, mumps and varicella but was not significantly related to protective IgG levels for rubella and HBV. Female gender was significantly related to a higher protection rate against Hepatitis B (87.8 vs 82.4%; p

Measles is one of the most contagious infectious diseases. Measles vaccine, which has been introduced in Italy in 1979, is highly effective in preventing the disease (two-dose vaccine effectiveness is 99%). In 2017, Italy was the second country of EU for number of cases of measles. A study conducted in the same year showed that 22.3% of measles infection happened in hospital settings and 6.6% of cases occurred in HCWs. This risk group showed low rates of adhesion to the vaccination campaign. For this reason, we hypothesized that workplace vaccination could lead to better vaccination rates in HCWs. Moreover, we focused the vaccination campaign on a specific target group composed of HCWs not serologically immune and previously not vaccinated. We analyzed the clinical records of measles-specific IgG antibodies of 2,940 HCWs, that underwent occupational health surveillance between 1 January 2017 and 31 December 2017. 15.3% (450) was seronegative for measles, especially in the age group under 35 years. We compared the costs related to strategies with and without serological screening. Our study confirmed that immunization strategy with pre-vaccination screening was cost-effective compared to the vaccination without screening. In our sample, in fact, administration of two dose vaccine only susceptible HCWs determine a saving of 146,262 €. The vaccination of HCWs remains a topical issue in preventing the transmission of infectious disease in the hospital setting. Due to the cost-effectiveness evaluation, we recommend extending the pre-vaccination screening to identify the real susceptible workers.

Health Care Workers (HCWs) have an increased risk of contracting contagious disease, including mumps. In January 2017 the Italian National Vaccine Prevention Plan 2017–2019, recommended the administration of a dose of MMR vaccine (Measles-Mumps-Rubella) to the Health Care Workers (HCWs) that, working in a risky environment, did not carry out the complete vaccination cycle of MMR or that are seronegative for at least one of the three vaccine viruses. In October of the same year, the Advisory Committee on Immunization Practices (ACIP) recommended a third dose of a vaccine containing Mumps Virus for people previously vaccinated with 2 doses, belonging to a group or to a population at increased risk of acquire mumps in the event of an epidemic. We analyzed the clinical records and values of mumps-specific IgG antibodies of 3032 HCWs (mean age 32.80 ± 10.75 years), that underwent occupational health surveillance between January 1st 2017 and March 31th 2018. The HCWs were also screened for measles, rubella, mumps using serological methods. 13% (405) was seronegative for mumps, especially among HCWs between 18 and 36 years. We calculated the cost-effectiveness of two-doses and three-doses MMR vaccination. The cost of vaccination without screening was significantly more expensive (cost difference: 99 712 € and 184 996 €) both in case of two-dose and three-dose MMR vaccination respectively. Our study suggests that, in HCWs, the assessment of the mumps antibody titer before vaccination may be a useful complement to vaccination itself, because it is more accurate and cost-effective than direct immunization of unvaccinated subjects.
