Clinicians involved in PAD care understand that timing is a key factor in limb salvage and acute critical limb ischemia patient survival. These delayed presentations clearly demonstrate a population that is in fear of presenting to an overwhelmed health system. The underdiagnoses in hospitalized patients could be related to incomplete physical examinations in poorly communicating isolated elderly patients (who may already have oxygen support and painkillers to treat high-grade fever). These underdiagnoses could also be related to the aforementioned lack of personal protection equipment that currently affects the entire health care system.
