Disentangling the impact of COVID-19 infection on clinical outcomes and preventive strategies in older persons: an Italian perspective

Italy was one of the first western countries to embrace the first wave of COVID-19 and undergo detrimental outcomes in older adults in different clinical settings, especially in those with comorbidity and frailty. In addition, older nursing home (NH) residents had significantly higher mortality rates most likely due to the increased susceptibility of infection due to combined physical vulnerability and risks linked to the NH living environment itself.Different reports throughout Italy have rapidly highlighted selected outcomes related to COVID-19 in older patients being treated in acute and long-term care (LTC) settings. However, the majority of these studies are single center studies. Thus, it remains fundamental to collect large data from prospective based-population studies in order to identify preventive and therapeutic COVID-19 risk/protective factors correlated with COVID-19 health status outcomes.In this commentary paper, we will discuss different Italian reports according to clinical settings and highlight the importance of GeroCovid Observational and GeroCovid Vax, two large population based prospective studies in Italy.
