Research Article: Grip Strength is a Predictor for Subsyndromal Delirium Among Older Adults Following Joint Replacement
Abstract:
Delirium is an acute neurocognitive dysfunction characterized by fluctuating consciousness and obvious impairment of cognition, such as inattention, disorientation, disorganized thinking, agitation, and delusions This condition commonly occurs in older patients during the postoperative period (Postoperative delirium, POD) with a combined incidence of %. Delirium is recognized as a serious adverse event closely related to various negative consequences, including prolonged hospital admissions, cognitive function decline, and higher mortality, significantly undermining both life span and quality. In addition to full delirium syndromes, subsyndromal delirium (SSD), a milder form of delirium has been a topic of interest in recent decades., SSD is defined by the presence of partial delirium symptoms or a precursory state of clinical delirium but does not yet meet the full diagnostic criteria of delirium., The incidence of SSD can be highly variable, ranging from .% to .%, and close to delirium, patients who develop SSD are associated with unfavorable outcomes as well, such as extended duration of hospitalization, long-term functional disability, and cognitive impairment. Not only that, in previous studies, risk factors of SSD have also been identified as similar to those associated with delirium, like advanced age, preoperative fasting times, psychotropic medications, cognitive impairment, acute stroke, hearing and visual impairment, and frailty., Consequently, it could be considered that risk factors of delirium could also be intrinsic factors in those of subsyndromal delirium.
