Thrombocytopenia is common in ICUs and constitutes a simple and readily available risk marker for mortality, independent of and complementary to established severity of disease indices. Both a low nadir platelet count and a large fall of platelet count predict a poor vital outcome in adult ICU patients.

Objectives: To determine the association between frailty and short-term mortality in older adults hospitalized for coronavirus disease 2019 . Design: Retrospective single-center observational study. Setting and participants: Eighty-one patients with COVID-19 confirmed by reverse-transcriptase polymerase chain reaction (RT-PCR), at the Geriatrics department of a general hospital in Belgium. Measurements: Frailty was graded according to the Rockwood Clinical Frailty Scale (CFS). Demographic, biochemical, and radiologic variables, comorbidities, symptoms, and treatment were extracted from electronic medical records. Results: Participants (N ¼ 48 women, 59%) had a median age of 85 years (range 65-97 years) and a median CFS score of 7 (range 2-9); 42 (52%) were long-term care residents. Within 6 weeks, 19 patients died. Mortality was significantly but weakly associated with age (Spearman r ¼ 0.241, P ¼ .03) and CFS score (r ¼ 0.282, P ¼ .011), baseline lactate dehydrogenase (LDH; r ¼ 0.301, P ¼ .009), lymphocyte count (r ¼ À0.262, P ¼ .02), and RT-PCR cycle threshold (Ct, r ¼ À0.285, P ¼ .015). Mortality was not associated with long-term care residence, dementia, delirium, or polypharmacy. In multivariable logistic regression analyses, CFS, LDH, and RT-PCR Ct (but not age) remained independently associated with mortality. Both age and frailty had poor specificity to predict survival. A multivariable model combining age, CFS, LDH, and viral load significantly predicted survival. Conclusions and Implications: Although their prognosis is worse, even the oldest and most severely frail patients may benefit from hospitalization for COVID-19, if sufficient resources are available.

The overall rankings of the needs by the three groups are very similar. Information emerges as most important factor, with considerably less importance attached to comfort and support. There were significant differences between the groups on all categories and on 24 individual needs. Regarding the need categories, both nurses and physicians underestimate the relatives' need for information and proximity to the patient. Physicians also underestimate the relatives' need for assurance. On the individual need items, relatives' needs are generally underestimated by the staff, but in some cases overestimations are found.
