However, there is no information available regarding the impact of frailty over time in severe COVID-19 patients admitted to the ICU mainly due to small sample sizes, or heterogeneity in frailty determination criteria. A recent individual patient data meta-analysis that included 2001 patients admitted to ICU with coronavirus disease 2019 and found that frailty patients had worse clinical outcomes such as a greater hospital mortality when compared with non-frail patients (65.2% vs 41.8%; <span class="elsevierStyleItalic">P</span> = .001, respectively).<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">19</span></a> To our knowledge, this is the first well-characterized descriptive, observational study to assess frailty of COVID-19 survivors who underwent ICU stay over time.

However, it is unclear whether frailty screening on admission to the ICU can be useful as a prognostic tool. A recent study evaluated the association between baseline assessment of frailty scores and disability in instrumental activities of every day living in critically ill patients, and found that those patients with worse clinical frailty before developing critical illness were 20% and 30% less likely to be able to carry out instrumental activities of every day living at 3 and 12 months, respectively.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">26</span></a> In the present study, the majority of patients experienced a decrease in frailty categories, and only 20.4% of robust patients at ICU admission remained in the same category after 6 months of ICU treatment, which highlighted the clinical relevance of the assessment of frailty at baseline.

In fact, only the need of invasive mechanical ventilation in severe COVID-19 patients had an independent three fold increase in the odds of frailty at 6-month follow-up. Likewise, the ICU survivors resulted in a worse physical health-related quality of life at 1-year follow-up.<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">28</span></a> On the other hand, despite pre-ICU health status could be associated with post-ICU health problems, the baseline frailty status itself prior to ICU admission could be also considered as a risk factor for the deterioration of ICU survivors. However, our results based on the sensitivity analysis of the predictive model have shown that basal frailty is not independently associated with the deterioration. Further studies however should be addressed to establish the specific association between the baseline frailty status with the deterioration of health status after ICU admission in a long-term follow-up.</p><p id="par0160" class="elsevierStylePara elsevierViewall">The strength of these independent associations was not affected by age, indicating that patients of all ages along the fitness to frail continuum are at risk for poor outcomes after critical illness, regardless the reason for the ICU admission.</p><p id="par0165" class="elsevierStylePara elsevierViewall">This study may set the starting point for future work in several ways. Whereas frailty has frequently been used for screening and risk stratification in clinical subpopulations,<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">29</span></a> our findings suggest that frailty may be a useful measure of risk of clinical worsening among a broader population of critically ill patients after ICU stay.</p><p id="par0170" class="elsevierStylePara elsevierViewall">While this study provides potentially important insights, there are limitations that should be considered. First, limitations in data availability prevented us from evaluating the role of underlying factors, such as chronic inflammation, nutrition, medications, or genetics, which may explain or mediate associations between frailty and worsening of clinical functional outcomes. Second, these findings are limited by the absence of a control group and, because it is unclear whether COVID-19 showed a unique phenotype and implication in a different risk stratification of impairment of frailty in survivors. The limited information in the literature on the effect of ICU treatment on fragility related with any reason and critically ill phenotype adds relevance to our study. Further research is needed to understand longer-term outcomes and whether these findings may reflect associations with the disease.</p><p id="par0175" class="elsevierStylePara elsevierViewall">Third, this study has been validated in community-dwelling Mexican adults, but post-ICU care, the local clinical practices, and the Mexican Health Care System itself may limit the registry of the results.</p></span><span id="sec0060" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0165">Conclusions</span><p id="par0180" class="elsevierStylePara elsevierViewall">Frailty score deterioration was reported frequently among survivors critically ill patients with severe COVID-19 at 6 months.
