RESUMEN
Antibody studies analyze immune responses to SARS-CoV-2 vaccination and infection, which is crucial for selecting vaccination strategies. In the KoCo-Impf study, conducted between 16 June and 16 December 2021, 6088 participants aged 18 and above from Munich were recruited to monitor antibodies, particularly in healthcare workers (HCWs) at higher risk of infection. Roche Elecsys® Anti-SARS-CoV-2 assays on dried blood spots were used to detect prior infections (anti-Nucleocapsid antibodies) and to indicate combinations of vaccinations/infections (anti-Spike antibodies). The anti-Spike seroprevalence was 94.7%, whereas, for anti-Nucleocapsid, it was only 6.9%. HCW status and contact with SARS-CoV-2-positive individuals were identified as infection risk factors, while vaccination and current smoking were associated with reduced risk. Older age correlated with higher anti-Nucleocapsid antibody levels, while vaccination and current smoking decreased the response. Vaccination alone or combined with infection led to higher anti-Spike antibody levels. Increasing time since the second vaccination, advancing age, and current smoking reduced the anti-Spike response. The cumulative number of cases in Munich affected the anti-Spike response over time but had no impact on anti-Nucleocapsid antibody development/seropositivity. Due to the significantly higher infection risk faced by HCWs and the limited number of significant risk factors, it is suggested that all HCWs require protection regardless of individual traits.

AIM OF THE WORK: The aim of this study was to measure and compare the relative importance that patients with multimorbidity, partners and other informal caregivers, professionals, payers and policy makers attribute to different outcome measures of integrated care (IC) programmes in Germany. METHODS: A DCE was conducted, asking respondents to choose between two IC programmes for persons with multimorbidity. Each IC programme was presented by means of attributes or outcomes reflecting the Triple Aim. They were divided into the outcomes health/ wellbeing, experience with care and costs with in total eight attributes and three levels of performance. RESULTS: The results of n=676 questionnaires showed that the attributes "enjoyment of life" and "continuity of care" received the highest ratings across all stakeholder groups. The lowest relative scores remained for the attribute "total costs" for all stakeholders. The preferences of professionals and informal caregivers differed most distinctly from the patients' preferences. The differences mostly concerned "physical functioning", which was rated highest by patients, and "person centeredness" and "continuity of care", which received the highest ratings from professionals. CONCLUSIONS: The preference heterogeneities identified in relation to the outcomes of IC programmes between different stakeholders highlight the importance of informing professionals and policy makers about the different perspectives in order to optimise the design of IC programmes. The results also support the relevance of joint decision-making and coordination processes between professionals, informal caregivers and patients.
