COVID-19 vaccination among health care workers in Finland: coverage, perceptions and attitudes.

AIMS: In this study, we examined the voluntary COVID-19 vaccine coverage among health care workers (HCWs) working in close patient contact. HCWs' beliefs about COVID-19 infection, their opinions of vaccination and reasons for having or declining the COVID-19 vaccination were also evaluated. METHODS: In October 2021, a cross-sectional observational study was carried out in five hospitals in Central and Eastern Finland. The anonymous and voluntary survey was targeted at 5120 doctors and nurses working in close patient contact. RESULTS: Some 1837 responses were included in the study. Ninety-seven per cent of the respondents had received at least one COVID-19 vaccine and 68% of the respondents agreed that all HCWs working in close patient contact should be vaccinated against COVID-19. Vaccination coverage and support for vaccination were higher among older HCWs and doctors. HCWs' main reasons for having the COVID vaccine were willingness to protect themselves, their family and their patients from COVID-19. Concerns about adverse reactions to the COVID-19 vaccine was the main reason for declining it. CONCLUSIONS: The overall COVID-19 vaccination coverage and support for vaccinations among HCWs working in close patient contact were high without actual mandatory policies being introduced. Prioritising HCWs for COVID-19 vaccinations and widespread vaccine availability, as well as low general vaccine hesitancy and high seasonal influenza vaccination coverage among the study population were check marks in achieving high COVID-19 vaccination coverage rapidly.

Short- and long-term effects of imatinib in hospitalized COVID-19 patients: A randomized trial.

OBJECTIVES: We studied the short- and long-term effects of imatinib in hospitalized COVID-19 patients. METHODS: Participants were randomized to receive standard of care (SoC) or SoC with imatinib. Imatinib dosage was 400 mg daily until discharge (max 14 days). Primary outcomes were mortality at 30 days and 1 year. Secondary outcomes included recovery, quality of life and long COVID symptoms at 1 year. We also performed a systematic review and meta-analysis of randomized trials studying imatinib for 30-day mortality in hospitalized COVID-19 patients. RESULTS: We randomized 156 patients (73 in SoC and 83 in imatinib). Among patients on imatinib, 7.2% had died at 30 days and 13.3% at 1 year, and in SoC, 4.1% and 8.2% (adjusted HR 1.35, 95% CI 0.47-3.90). At 1 year, self-reported recovery occurred in 79.0% in imatinib and in 88.5% in SoC (RR 0.91, 0.78-1.06). We found no convincing difference in quality of life or symptoms. Fatigue (24%) and sleep issues (20%) frequently bothered patients at one year. In the meta-analysis, imatinib was associated with a mortality risk ratio of 0.73 (0.32-1.63; low certainty evidence). CONCLUSIONS: The evidence raises doubts regarding benefit of imatinib in reducing mortality, improving recovery and preventing long COVID symptoms in hospitalized COVID-19 patients.

Disease burden caused by respiratory syncytial virus compared with influenza among adults: a retrospective cohort study from Eastern Finland in 2017-2018.

OBJECTIVES: Respiratory syncytial virus (RSV) is one of the most important causes of lower respiratory tract illnesses. In this study, we examined the number and severity of RSV infections among adult patients. The underlying diseases and background information of patients with RSV were examined and compared with the patients with influenza. DESIGN: Retrospective cohort study. SETTING: Patients receiving tertiary care services in Kuopio University Hospital (KUH) district in Eastern Finland. PARTICIPANTS: 725 patients (152 with RSV infection and 573 with influenza) treated in KUH between November 2017 and May 2018. PRIMARY AND SECONDARY OUTCOME MEASURES: Hospitalisation and mortality. RESULTS: Compared with influenza, RSV caused a more serious disease in terms of hospitalisation (84.2% vs 66.0%, p<0.001), incidence of pneumonia (37.5% vs 23.2%, p<0.001), need for antibiotics (67.1% vs 47.3%, p<0.001) and supplemental oxygen (50.7% vs 31.2%, p<0.001). The all-cause mortality during hospitalisation and 30 days after discharge was higher among the RSV-infected patients (8.6% vs 3.5%, p=0.010). Solid malignancies (23.1% vs 5.0%, p=0.042) and chronic kidney disease (30.8% vs 5.8%, p=0.011) were more common among the RSV-infected non-survivors compared with survivors. RSV was an independent risk factor for hospitalisation (adjusted OR (aOR) 2.035; 95% CI 1.17 to 3.55) and mortality (aOR 2.288; 95% CI 1.09 to 4.81) compared with influenza. CONCLUSIONS: Among all the screened patients, those with RSV infection were older and had more underlying conditions than patients with influenza. They had increased likelihood of hospitalisation and mortality when compared with influenza. Solid malignancies and chronic kidney disease seemed to be independent risk factors for death among RSV-infected patients. During RSV and influenza epidemics, it is important to test patients with respiratory symptoms for RSV and influenza to prevent the spread of the infections among elderly and chronically ill patients.

Support among healthcare workers for the new mandatory seasonal influenza vaccination policy and its effects on vaccination coverage.

INTRODUCTION: Finland was the first European country to introduce a nation-wide mandatory seasonal influenza vaccination policy for healthcare workers (HCWs) by mandating that administrators of health care institutions only employ vaccinated HCWs. In this study, we examine the effects of the new policy and the view of HCWs on the new policy. METHODS: A cross-sectional observational study was conducted in Kuopio University Hospital among HCWs working in close patient contact. The statistics on vaccination coverage were obtained from the hospital's own databases, where employees were asked to self-report their suitability for work. An anonymous survey was sent to HCWs in 2015-2016 (n = 987) and 2018-2019 (n = 821). RESULTS: Vaccination coverage increased from 59.5 to 99.6%, according to the hospital's own records. Among the survey respondents, the seasonal influenza vaccination coverage of HCWs increased from 68.2 to 95.4%. 83.8% of doctors and 49.4% of nurses supported the new policy. 12.7% of doctors and 41.5% of nurses found the new mandate coercive or that it restricted their self-determination. CONCLUSIONS: Our study confirms the positive effects of mandating the administrators of health care institutions to only employ vaccinated HCWs. The majority (57.9%) of all HCWs supported the new policy, with doctors being more compliant than nurses. Key messages Finland became the first European country to mandate influenza vaccination for HCWs by mandating that administrators of health care institutions only employ vaccinated HCWs. After the new act, the vaccination coverage of HCWs increased close to 100%. Most of the HCWs supported the new act and did not find it coercive.

Mould specific IgG antibodies connected with sinusitis in teachers of mould damaged school: a two-year follow-up study.

OBJECTIVES: The aim of this study was to describe the relationship between mould exposure induced by moisture damage and mould specific immunoglobulin G antibodies to 20 common mould species and their association with respiratory diseases. MATERIALS AND METHODS: Mould specific immunoglobulin G (IgG) antibodies were monitored in teachers in a follow-up after an extensive mould remediation process in school buildings. IgG antibodies to 20 different microbes were determined from the sera of 26 teachers (19 exposed and 7 references) by enzyme-linked immunosorbent assay (ELISA). The serum samples were drawn twice, firstly at the completion of the remediation in the spring of 1997 and secondly, two years later in the spring of 1999. Health data was collected with self-administered questionnaires. RESULTS: No statistical differences were found in the overall concentrations of 20 mould-specific IgG-antibodies between the study and control groups at the beginning of the study. An association between sinusitis and elevated mould-specific IgG-levels forAspergillus fumigatus, Aspergillus versicolor, Aureobasidium pullulans, Chaetomium globosum, Cladosporium cladosporioides, Phialophora bubakii, Rhodotorula glutinis, Sporobolomyces salmonicolor, Stachybotrys atra, and Tritirachium roseum was found in the study group. CONCLUSIONS: In a two-year follow-up the total concentration of the IgG antibodies for Tr. toseum was lower at the end than at the beginning of the follow-up and this remained significant for the group of teachers with sinusitis. The decrease in mould specific IgG to Cl. cladosporioides, Geotrichum candidum, Ph. bubakii and Rhizopus nigricans was associated with bronchitis. According to our knowledge, this is the first study in which the association between elevated mould specific IgG antibodies and sinusitis was found in the school environment.

Effects of mould remediation on school teachers' health.

The follow-up study of the health of teachers (n = 56) of three mould damage schools were done with self-administered symptom questionnaire before and 1 year after the remediation of school buildings. Technical and microbiological investigations were done parallel at the same time. In the beginning of the study symptoms of allergic rhinitis, sinusitis, conjunctivitis and fatigue were high compared to normal population and 1 year after the intervention a decrease in fatigue (OR = 0.4) and headache (OR = 0.2) was observed. An association between female gender and sinusitis was found before the remediation (OR = 8.1). Age over 40 years was a risk factor for voice problems and more than 10 working years at the same school were associated with increased risk for conjunctivitis (OR = 8.5) and headache (OR = 5.4). Other exposure situations such as mould problems at home and mould exposure during leisure time also have an effect on teachers' health. Significant reduction was found in symptoms of fatigue and headache after the cessation of exposure, while respiratory symptoms need much longer time to relieve after the remediation. Age, female gender, atopy, long-term exposure time and other exposure situations might be the risk factors for prolonged symptoms among mould exposed teachers.
