Background Older people are particularly vulnerable to severe COVID-19. Little is known about long-term consequences of COVID-19 on health-related quality of life and functional status in older people, and the impact of age in this context. We aimed to study age-related change in health-related quality of life (HR-QoL), functional decline and mortality among older patients six months following hospitalisation due to COVID-19. Methods This was a cohort study including patients aged 60 years and older admitted to four general hospitals in South-Eastern Norway due to COVID-19, from March 1 up until July 1, 2020. Patients who were still alive were invited to attend a six-month follow-up. Change in HR-QoL and functional status compared to before the COVID-19 hospitalisation were assessed using the EuroQol 5-dimensional-5 levels questionnaire (EQ 5D-5L). A change in visual analogue scale (VAS) score of 7 or more was considered clinically relevant. Results Out of 216 patients aged 60 years and older that were admitted to hospital due to COVID-19 during the study period, 171 were still alive 180 days after hospital admission, and 106 patients (62%) attended the six-month follow-up. Mean age was 74.3 years, 27 patients (26%) had experienced severe COVID-19. 57 participants (54%) reported a decrease in the EQ5D-5L VAS score after six months, with no significant difference between persons aged 75 years and older compared to younger. 70 participants (66%) reported a negative change in any of the dimensions of the EQ-5D-5L, with impaired ability to perform activities of daily life (35%), reduced mobility (33%) and having more pain or discomfort (33%) being the most commonly reported changes. 46 participants (43%) reported a negative change in cognitive function compared to before the COVID-19 hospitalisation. Six-month mortality was 21%, and increased with increasing age. Conclusions More than half of the patients reported a negative change in HR-QoL six months following hospitalisation due to COVID-19, and one out of three experienced a persistently impaired mobility and ability to carry out activities of daily living. The results suggest awareness of long-term functional decline in older COVID-19 patients.

To investigate the association between hyperglycemia and in-hospital and 45-day mortality in acutely ill elderly patients.Retrospective cohort.Hospital medical patients admitted to a sub-intensive care unit (sub-ICU) for elderly patients, which is a level of care between ordinary wards and intensive care.One thousand two hundred twenty-nine patients (mean age 79.6+/-8.4) admitted to the sub-ICU from January 2003 to January 2006. Forty patients with acute myocardial infarction and 34 patients with extreme fasting glucose values (60 or500 mg/dL) were excluded. Eight hundred twenty-two patients without a history of diabetes mellitus (DM) and 333 patients with a diagnosis of DM were selected and subdivided into three categories according to serum fasting blood glucose: 60 to 126 mg/dL (Group A), 127 to 180 mg/dL (Group B), and 181 to 500 mg/dL (Group C).Age, sex, mental and functional status, Acute Physiology Score, comorbid conditions, serum albumin, serum cholesterol, fasting serum glucose, and length of stay. In-hospital mortality was the primary outcome, and 45-day mortality was the secondary outcome.Total in-hospital mortality was 14.5%. In patients with and without DM, mortality was 8.8% and 11.3%, respectively, in Group A; 13.6% and 17.3% in Group B, and 12.6% and 34.3% in Group C. After controlling for confounders, newly recognized hyperglycemia (181 mg/dL) was independently associated with in-hospital mortality (adjusted odds ratio=2.7, 95% confidence interval=1.6-4.8). Forty-five-day mortality in newly recognized hyperglycemic patients was 17.5%, 25.7%, and 42% in Groups A, B, and C, respectively, whereas it was 21.2% in patients with DM.In elderly patients, newly recognized hyperglycemia was associated with a higher mortality rate than in those with a prior history of DM. These data suggest that further randomized clinical trials are needed to assess the efficacy and the risk of a target glucose of greater than 180 mg/dL.
