Elderly patients represent a high-risk group with increased risk of death from COVID-19. Despite the number of published studies, several unmet needs in care for older adults exist.
To discuss unmet needs of COVID-19 in this special population.
A literature review for studies on COVID-19 in elderly patients published between December 2019 and November 2021 was performed. Clinical questions were formulated to guide the literature search. The search was conducted in the MEDLINE database, combining specific search terms. Two reviewers independently conducted the search and selected the studies according to the prespecified clinical questions.
Elderly patients with COVID-19 have peculiar characteristics. They may have atypical clinical presentation, with no fever and with delirium or neurological manifestations as the most common signs, with potential delayed diagnosis and increased risk of death. The reported fatality rates among elderly patients with COVID-19 are extremely high. Several factors, including comorbidities, atypical presentation, and exclusion from intensive care unit care, contribute to this excess of mortality. Age alone is frequently used as a key factor to exclude the elderly from intensive care, but there is evidence that frailty rather than age better predicts the risk of poor outcome in this category. Durability of vaccine efficacy in the elderly remains debated, and the need for a third booster dose is becoming increasingly evident. Finally, efforts to care for elderly patients who have survived after acute COVID-19 should be implemented, considering the high rates of long COVID sequelae and the risk of longitudinal functional and cognitive decline.
We highlight peculiar aspects of COVID-19 in elderly patients and factors contributing to high risk of poor outcome in this category. We also illuminated gaps in current evidence, suggesting future research directions and underlining the need for further studies on the optimal management of elderly patients with COVID-19.
老年患者是 COVID-19 死亡风险增加的高危人群。尽管已经发表了大量研究,但在老年患者的护理方面仍存在一些未满足的需求。
讨论 COVID-19 在这一特殊人群中的未满足需求。
对 2019 年 12 月至 2021 年 11 月期间发表的关于老年 COVID-19 患者的研究进行了文献回顾。制定了临床问题来指导文献检索。在 MEDLINE 数据库中进行了检索,结合了特定的检索词。两名审查员独立进行了检索,并根据预设的临床问题选择了研究。
COVID-19 的老年患者具有特殊的特征。他们可能表现出非典型的临床表现,没有发热,最常见的表现是谵妄或神经表现,可能导致延迟诊断和增加死亡风险。报道的 COVID-19 老年患者死亡率极高。包括合并症、非典型表现和排除在重症监护病房护理在内的几个因素导致了这种死亡率过高。年龄本身经常被用作将老年人排除在重症监护之外的关键因素,但有证据表明,衰弱而不是年龄更好地预测了这一人群不良结局的风险。疫苗在老年人中的疗效持久性仍存在争议,越来越明显的是需要第三剂加强针。最后,应该努力照顾从急性 COVID-19 中幸存下来的老年患者,考虑到长 COVID 后遗症的高发生率和纵向功能和认知下降的风险。
我们强调了 COVID-19 在老年患者中的特殊方面以及导致该类患者不良结局风险增加的因素。我们还阐明了当前证据中的空白,提出了未来的研究方向,并强调了对 COVID-19 老年患者最佳管理的进一步研究的必要性。
