Incidence of laboratory-confirmed influenza and RSV and associated presenteeism and absenteeism among healthcare personnel, Israel, influenza seasons 2016 to 2019.

ABSTRACT: BackgroundHealthcare personnel (HCP) are at high risk for respiratory infections through occupational exposure to respiratory viruses.AimWe used data from a prospective influenza vaccine effectiveness study in HCP to quantify the incidence of acute respiratory infections (ARI) and their associated presenteeism and absenteeism.MethodsAt the start and end of each season, HCP at two Israeli hospitals provided serum to screen for antibodies to influenza virus using the haemagglutination inhibition assay. During the season, active monitoring for the development of ARI symptoms was conducted twice a week by RT-PCR testing of nasal swabs for influenza and respiratory syncytial virus (RSV). Workplace presenteeism and absenteeism were documented. We calculated incidences of influenza- and RSV-associated ARI and applied sampling weights to make estimates representative of the source population.ResultsThe median age of 2,505 participating HCP was 41 years, and 70% were female. Incidence was 9.1 per 100 person-seasons (95% CI: 5.8-14.2) for RT-PCR-confirmed influenza and 2.5 per 100 person-seasons (95% CI: 0.9-7.1) for RSV illness. Each season, 18-23% of unvaccinated and influenza-negative HCP seroconverted. The incidence of seroconversion or RT-PCR-confirmed influenza was 27.5 per 100 person-seasons (95% CI: 17.8-42.5). Work during illness occurred in 92% (95% CI: 91-93) of ARI episodes, absence from work in 38% (95% CI: 36-40).ConclusionInfluenza virus and RSV infections and associated presenteeism and absenteeism were common among HCP. Improving vaccination uptake among HCP, infection control, and encouraging sick HCP to stay home are important strategies to reduce ARI incidence and decrease the risk of in-hospital transmission.

Project description:IntroductionDespite a longstanding Israel Ministry of Health recommendation that all healthcare personnel (HCP) receive a seasonal influenza vaccine, vaccine uptake among HCP remains below the country's target of 60% coverage. To understand factors related to vaccine hesitancy, we used data from a prospective three-year (2016-2019) influenza vaccine effectiveness study among Israeli HCP to examine knowledge, attitudes, and practices (KAP) about influenza vaccination and their association with vaccine uptake.MethodsAt the start of each influenza season, all participating HCP completed a questionnaire that included questions about socio-demographic and occupational characteristics, health status, and KAP related to seasonal influenza vaccination. We extracted vaccination history from electronic medical records and employee vaccination registries. We used logistic regression models to identify demographic and occupational factors, and KAP about influenza vaccination, associated with receipt of vaccination.ResultA total of 2,126 HCP were enrolled and had available data on vaccination history. Their median age was 42 years [IQR 35-52], and 73 % self-identified as female. Influenza vaccine uptake in 2016, 2017 and 2018 was 46 %, 48 % and 47 %, respectively. Overall, 36 % of HCP had received an influenza vaccine in ≥ 4 of the eight years prior. HCP aged 35-49 years were less likely to receive influenza vaccine compared to HCP aged ≥ 50 years (OR: 0.81 [95 % CI: 0.67-0.98]). Nurses and allied personnel were less likely to receive influenza vaccine compared to physicians (OR: 0.63 [95 % CI: 0.50-0.78] and OR: 0.53 [95 % CI: 0.40-0.70], respectively). The emotional benefit of vaccination (e.g., anticipating regret if not vaccinated) and the perception of vaccine safety were factors associated with vaccine uptake (OR: 7.60 [95 % CI: 6.27-9.22] and OR: 3.43 [95 % CI:2.91-4.03], respectively).ConclusionAmong HCP at two hospitals in Israel, less than half received an annual influenza vaccine. Older HCP, physicians, and those who reported the emotional benefit of vaccination or agreed that influenza vaccines are safe were more likely to be vaccinated. Future influenza vaccination campaigns could focus on these demographic groups and tailor messages emphasizing the emotional benefits of vaccination and vaccine safety to increase seasonal influenza vaccine uptake among HCP in Israel.

Project description:IntroductionAcute lower respiratory infections (ALRIs) are a major contributor to the global infectious disease burden and a common cause of hospitalisation for children under 2 years. We compared clinical severity in children hospitalised with respiratory syncytial virus (RSV), parainfluenza virus (PIV), human metapneumovirus (hMPV) and influenza virus (IFV).MethodsWe used a probabilistically linked population cohort born in Western Australia between 2010 and 2020 and hospitalised before the age of 2 years. Outcomes compared included length of hospital stay (LOS), admission to intensive care unit (ICU), need for respiratory support (RS), complex hospital course (RS, death, ICU admission or LOS >75th percentile), 7-day and 30-day mortality, hospital-in-the-home care, 30-day all-cause and ALRI-specific readmissions and emergency department presentations 14 days prior to hospitalisation. Logistic regression was used for binary outcomes, and negative binomial regression was used for discrete count variables. Incidence rates, time to RS and time to readmissions were calculated using survival analysis techniques.ResultsThe final cohort included 210 997 hospitalised children under 24 months of age for a total of 315 769 admissions. Infants hospitalised before 6 months had the highest rates for all virus-specific hospitalisations, particularly RSV hospitalisations (50.4 per 1000 child-years (95% CI 48.7 to 52.1)). Infants <6 months had higher odds of an ICU admission (adjusted OR (aOR) 2.39, 95% CI 1.36 to 4.19) and RS (aOR 4.68, 95% CI 2.95 to 7.44) and a complex hospital course (aOR 2.69, 95% CI 2.13 to 3.42) with RSV and four times higher hazards of requiring RS earlier (adjusted HR (aHR) 4.06, 95% CI 2.59 to 6.36). An ALRI-coded 30-day readmission was recorded in 10%-24% of virus-specific hospitalisations.DiscussionYoung infants have a more severe and complex hospital course with RSV hospitalisation compared with hospitalisation with other respiratory viruses and should be prioritised for prevention measures such as the single-dose monoclonal antibody, nirsevimab.
