Still, knowledge on the role of vulnerability is pivotal in understanding the resilience of older people during acute illness, and hence important for future pandemic preparedness. Therefore, we assessed the predictive value of different routine care-based vulnerability measures in addition to age and sex for 28-day mortality in an older primary care population of patients with COVID-19.<h4>Methods</h4>From primary care medical records using three routinely collected Dutch primary care databases, we included all patientBMC primary careLimited incremental predictive value of the frailty index and other vulnerability measures from routine care data for mortality risk prediction in older patients with COVID-19 in primary care.PMC1088537210430102110005la Roi-Teeuw HMMooijaart SPvan den Dries CJPolinder-Bos HAvan Smeden MGussekloo JLuijken KGeersing GJBlom MTfalseLimited incremental predictive value of the frailty index and other vulnerability measures from routine care data for mortality risk prediction in older patients with COVID-19 in primary care.<h4>Background</h4>During the COVID-19 pandemic, older patients in primary care were triaged based on their frailty or assumed vulnerability for poor outcomes, while evidence on the prognostic value of vulnerability measures in COVID-19 patients in primary care was lacking.
