ABSTRACT
BACKGROUND: There have been concerns about COVID-19 vaccination safety among frail older individuals. We investigated the relationship between COVID-19 mRNA vaccination and mortality among individuals aged ≥ 70 years and whether mortality varies across four groups of health services used. METHODS: In this nationwide cohort study, we included 688,152 individuals aged ≥ 70 years at the start of the Norwegian vaccination campaign (December 27, 2020). We collected individual-level data from theNorwegian Emergency Preparedness Register for COVID-19. Vaccinated and unvaccinated individuals were matched (1:1 ratio) on the date of vaccination based on sociodemographic and clinical characteristics. The main outcome was all-cause mortality during 21 days after first dose of COVID-19 mRNA vaccination. Kaplan-Meier survival functions were estimated for the vaccinated and unvaccinated groups. We used Cox proportional-hazards regression to estimate hazard ratios (HRs) of death between vaccinated and unvaccinated individuals, with associated 95% confidence intervals (CIs), overall and by use of health services (none, home-based, short- and long-term nursing homes) and age group. RESULTS: Between December 27, 2020, and March 31, 2021, 420,771 older individuals (61.1%) were vaccinated against COVID-19. The Kaplan-Meier estimates based on the matched study sample showed a small absolute risk difference in all-cause mortality between vaccinated and unvaccinated individuals, with a lower mortality in the vaccinated group (overall HR 0.28 [95% CI: 0.24-0.31]). Similar results were obtained in analyses stratified by use of health services and age group. CONCLUSION: We found no evidence of increased short-term mortality among vaccinated individuals in the older population after matching on sociodemographic and clinical characteristics affecting vaccination and mortality.
ABSTRACT
BACKGROUND: Equal access to healthcare is a core principle in Norway's public healthcare system. The COVID-19 pandemic challenged healthcare systems in the early phase - in particular, related to testing and hospital capacity. There is little knowledge on how older people experienced being infected with an unfamiliar and severe disease, and how they experienced the need for healthcare early in the pandemic. AIM: To explore the experiences of older people infected by COVID-19 and their need for testing and hospitalisation. RESEARCH DESIGN: An explorative and descriptive approach, with qualitative interviews conducted in October 2020. PARTICIPANTS AND RESEARCH CONTEXT: Seventeen participants above 60 years of age hospitalised due to COVID-19 during spring 2020 were recruited 6 months after discharge. ETHICAL CONSIDERATIONS: Ethical approval was granted by the Regional Committee for Medical and Health Research Ethics in South-Eastern Norway (155425). FINDINGS: The main finding was that the informants experienced vulnerability and arbitrariness. This finding was supported by three sub-themes: experiences with a severe and unfamiliar disease, the strict criteria and the importance of someone advocating needs. DISCUSSION: Participants described varying access to healthcare. Those who did not meet the national criteria to be tested or hospitalised struggled against the system. Findings reveal arbitrary access to healthcare, in contrast to Norway's ethical principle of fair and just access to health services. Moreover, to access and receive necessary healthcare, informants were dependent on their next-of-kin's advocacy. CONCLUSION: Even when dealing with an unfamiliar disease, health professionals' assessments of symptoms must be performed with an ethical obligation to applicate competent appraisal and the exercise of discernment; this is in line with care ethics and ethical standards for nurses. These perspectives are a significant part of caring and the intension of doing good.
