Psychological and Functional Impact of COVID-19 in Long-Term Care Facilities: The COVID-A Study.

OBJECTIVE: To analyze the psychological and functional sequelae of the COVID-19 pandemic among older adults living in long term care facilities (LTCFs). DESIGN: Cohort longitudinal study SETTING ANT PARTICIPANTS: A total of 215 residents ≥ 65 years without moderate-to-severe cognitive impairment, living in five LTCFs in Albacete (Spain). MEASUREMENTS: Baseline on-site data were collected between March - June 2020 and three-month follow-up between June to September 2020. Symptoms of depression, anxiety, posttraumatic stress disorder (PTSD), and sleep disturbances were measured as psychological variables. Disability in basic activities of daily living (BADL), ambulation and frailty were assessed as functional variables. Differences were analyzed in relation to level of comorbidity and test positivity for COVID-19. RESULTS: At baseline, residents with COVID-19 presented worse functionality, higher frailty levels and malnutrition risk compared to non-COVID-19 residents. At three-month follow-up, higher rates of clinically significant depressive symptoms (57.7%), anxiety symptoms (29.3%), PTSD symptoms (19.1%) and sleep disturbances (93.0%) were found among residents regardless of COVID status. Thus, among 215 residents, 101 (47%) experienced a decline in BADL from baseline to the 3-month follow-up (median functional loss = 5 points in Barthel Index). In multivariate analyses, COVID-19 status did not explain either the functional or the ambulation loss. By contrast, residents with low comorbidity and COVID-19 presented higher PTSD symptoms (effect 2.58; 95% CI 0.93 to 4.23) and anxiety symptoms (effect 2.10; 95% CI 0.48 to 3.73) compared to the low comorbidity/non-COVID19 group. CONCLUSION: COVID-19 pandemic was associated, after three-months, with high psychological impact in older adults in LTCFs., specifically with higher post-traumatic stress and anxiety symptoms. Functional decline did not differ in relation to COVID-19 status but could be related to isolation strategies used for pandemic control.

Frailty, depression risk and 10-year hospitalization in older adults. The FRADEA study.

OBJECTIVES: To determine whether the interaction between frailty status and depression risk is associated with hospitalization density in older adults. METHODS: Ongoing cohort study in 794 subjects aged over 70 years from Albacete (Spain). Data were collected on depression risk, frailty, hospitalizations, and covariates. Participants were categorized into six groups. RESULTS: Adjusted hospitalization risk was higher for groups of prefrail/-non depression risk (HR 1.48; 95% confidence interval (CI) 1.16-1.89), prefrail/depression risk (HR 1.73; 95% CI 1.29-2.30), frail/non depression risk (HR 1.79; 95% CI 1.22-2.62), and frail/depression risk (HR 2.12; 95% CI 1.49-3.02), compared with robust/non depression risk group (p<0.01). Frail and prefrail groups presented increased hospitalization density in the first four follow-up years. CONCLUSIONS: Depression risk changes the yearly probabilities of hospitalization in prefrail and frail groups, increasing them in the first years. Depression risk should be monitored in prefrail and frail older adults as an independent risk factor for hospitalization.

Usability, User Experience, and Acceptance Evaluation of CAPACITY: A Technological Ecosystem for Remote Follow-Up of Frailty.

Frailty predisposes older persons to adverse events, and information and communication technologies can play a crucial role to prevent them. CAPACITY provides a means to remotely monitor variables with high predictive power for adverse events, enabling preventative personalized early interventions. This study aims at evaluating the usability, user experience, and acceptance of a novel mobile system to prevent disability. Usability was assessed using the system usability scale (SUS); user experience using the user experience questionnaire (UEQ); and acceptance with the technology acceptance model (TAM) and a customized quantitative questionnaire. Data were collected at baseline (recruitment), and after three and six months of use. Forty-six participants used CAPACITY for six months; nine dropped out, leaving a final sample of 37 subjects. SUS reached a maximum averaged value of 83.68 after six months of use; no statistically significant values have been found to demonstrate that usability improves with use, probably because of a ceiling effect. UEQ, obtained averages scores higher or very close to 2 in all categories. TAM reached a maximum of 51.54 points, showing an improvement trend. Results indicate the success of the participatory methodology, and support user centered design as a key methodology to design technologies for frail older persons. Involving potential end users and giving them voice during the design stage maximizes usability and acceptance.

Immunogenicity after 6 months of BNT162b2 vaccination in frail or disabled nursing home residents: The COVID-A Study.

BACKGROUND: There is incomplete information regarding evolution of antibody titers against SARS-CoV-2 after a two-dose strategy vaccination with BNT162b2 in older adults in long-term care facilities (LTCFs) with frailty, disability, or cognitive impairment. We aimed to determine IgG antibody titer loss in older adults in LTCFs. METHODS: This is a multicenter longitudinal cohort study including 127 residents (90 females and 37 males) with a mean age of 82.7 years (range 65-99) with different frailty and disability profiles in two LTCFs in Albacete, Spain. Residents received two doses of BNT162b2 as per label, and antibody levels were determined 1 and 6 months after the second dose. Age, sex, previous history of coronavirus disease 2019 (COVID-19), comorbidity (Charlson Index), performance in activities of daily living (Barthel Index), frailty (FRAIL instrument), and cognitive status were assessed. RESULTS: The mean antibody titers 1 and 6 months after the second vaccine dose were 32,145 AU/ml (SD 41,206) and 6182 AU/ml (SD 13,316), respectively. Across all participants, the median antibody titer loss measured 77.6% (interquartile range [IQR] 23.8%). Notably, the decline of titers in individuals with pre-vaccination COVID-19 infection was significantly lower than in those without a history of SARS-CoV-2 infection (72.2% vs. 85.3%; p < 0.001). The median titer decrease per follow-up day was 0.47% (IQR 0.14%) and only pre-vaccination COVID-19 was associated with lower rate of antibody decline at 6 months (hazard ratio 0.17; 95% confidence interval 0.07-0.41; p < 0.001). Frailty, disability, older age, cognitive impairment, or comorbidity were not associated with the extent of antibody loss. CONCLUSIONS: Older adults in LTCFs experience a rapid loss of antibodies over the first 6 months after the second dose of BNT162b2 vaccine. Only pre-vaccination COVID-19 is associated with a slower rate of antibody decrease. Our data support immunization with a third dose in this vulnerable, high-risk population.

Immunogenicity of the BNT162b2 vaccine in frail or disabled nursing home residents: COVID-A study.

BACKGROUND/OBJECTIVES: The safety and immunogenicity of the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine in older adults with different frailty and disability profiles have not been well determined. Our objective was to analyze immunogenicity of the BNT162b2 mRNA COVID-19 vaccine in older adults across frailty and disability profiles. DESIGN: Multicenter longitudinal cohort study. SETTING AND PARTICIPANTS: A total of 134 residents aged ≥65 years with different frailty and disability profiles in five long-term care facilities (LTCFs) in Albacete, Spain. INTERVENTION AND MEASUREMENTS: Residents were administered two vaccine doses as per the label, and antibody levels were determined 21.9 days (SD 9.3) after both the first and second dose. Functional variables were assessed using activities of daily living (Barthel Index), and frailty status was determined with the FRAIL instrument. Cognitive status and comorbidity were also evaluated. RESULTS: Mean age was 82.9 years (range 65-99), and 71.6% were female. The mean antibody titers in residents with and without previous COVID-19 infection were 49,878 AU/ml and 15,274 AU/ml, respectively (mean difference 34,604; 95% confidence interval [CI]: 27,699-41,509). No severe adverse reactions were observed, after either vaccine dose. Those with prevaccination COVID-19 had an increased antibody level after the vaccine (B = 31,337; 95% CI: 22,725-39,950; p < 0.001). Frailty, disability, older age, sex, cognitive impairment, or comorbidities were not associated with different antibody titers. CONCLUSIONS: The BNT162b2 mRNA COVID-19 vaccine in older adults is safe and produces immunogenicity, independently of the frailty and disability profiles. Older adults in LTCFs should receive a COVID-19 vaccine.

Baricitinib reduces 30-day mortality in older adults with moderate-to-severe COVID-19 pneumonia.

BACKGROUND: Older adults are at the highest risk of severe disease and death due to COVID-19. Randomized data have shown that baricitinib improves outcomes in these patients, but focused stratified analyses of geriatric cohorts are lacking. Our objective was to analyze the efficacy of baricitinib in older adults with COVID-19 moderate-to-severe pneumonia. METHODS: This is a propensity score [PS]-matched retrospective cohort study. Patients from the COVID-AGE and Alba-Score cohorts, hospitalized for moderate-to-severe COVID-19 pneumonia, were categorized in two age brackets of age <70 years old (86 with baricitinib and 86 PS-matched controls) or ≥70 years old (78 on baricitinib and 78 PS-matched controls). Thirty-day mortality rates were analyzed with Kaplan-Meier and Cox proportional hazard models. RESULTS: Mean age was 79.1 for those ≥70 years and 58.9 for those <70. Exactly 29.6% were female. Treatment with baricitinib resulted in a significant reduction in death from any cause by 48% in patients aged 70 or older, an 18.5% reduction in 30-day absolute mortality risk (n/N: 16/78 [20.5%] baricitinib, 30/78 [38.5%] in PS-matched controls, p < 0.001) and a lower 30-day adjusted fatality rate (HR 0.21; 95% CI 0.09-0.47; p < 0.001). Beneficial effects on mortality were also observed in the age group <70 (8.1% reduction in 30-day absolute mortality risk; HR 0.14; 95% CI 0.03-0.64; p = 0.011). CONCLUSIONS: Baricitinib is associated with an absolute mortality risk reduction of 18.5% in adults older than 70 years hospitalized with COVID-19 pneumonia.

[Nutritional status in older adults admitted to an acute geriatric unit]. / Estado nutricional de ancianos hospitalizados en una unidad geriátrica de agudos.

INTRODUCTION: Objective: to describe the nutritional status of older adults hospitalized in an acute geriatric unit (AGU) and its association with mortality and days of hospitalization. Material and methods: a retrospective study in 1,084 adults older than 65 years, hospitalized in an AGU. The Mini Nutritional Assessment®-Short Form (MNA®-SF) and subjective global assessment (SGA) were used. The association between nutritional status, mortality, and long hospital stay (> 7 days) was analyzed using regression models and Cox hazard models. Results: mean age was 86.5 years: 58.7% were women. Mean MNA®-SF score was 8.9 (20.0%, well nourished; 48.2%, at nutritional risk, and 31.7% with malnutrition). Using the SGA, 22.1% were well nourished, 54.7% had moderate malnutrition, and 23.2% had severe malnutrition. Agreement between SGA and MNA®-SF was good (kappa, 0.654; p < 0.001), and correctly classified 78.5% of participants. Malnutrition was associated with poorer cognitive status, greater disability, worse ambulation, and lower levels of total protein, albumin, cholesterol, and transferrin. Patients with malnutrition in the MNA®-SF assessment had a higher adjusted mortality risk than those who were well nourished (HR, 1.80; 95% CI, 1.01-3.20), same as those with SGA C versus A (HR, 1.66; 95% CI, 0.96-2.86). Patients with SGA B and C presented a higher adjusted risk of long hospitalization as compared to well nourished subjects (OR, 1.42; 95% CI, 1.04-1.96 and OR, 1.73; 95% CI, 1.18-2.54, respectively. Patients with malnutrition per the MNA-SF® presented a higher adjusted risk of long hospitalization as compared to well nourished subjects (OR, 1.59; 95% CI, 1.09-2.33). Conclusions: nutritional risk and malnutrition are very common in older adults in AGUs, and are associated with higher mortality and longer hospital stay.

INTRODUCCIÓN: Objetivo: describir el estado nutricional de los mayores hospitalizados en una unidad geriátrica de agudos (UGA) y su asociación con la mortalidad y la estancia hospitalaria. Material y métodos: estudio retrospectivo de 1084 personas mayores de 65 años en una UGA. Se emplearon el Mini Nutritional Assessment®-Short Form (MNA®-SF) y la valoración global subjetiva (VGS). La asociación entre estado nutricional, mortalidad y estancia hospitalaria prolongada (> 7 días) se analizó mediante un modelo de regresión y el análisis de riesgos de Cox. Resultados: edad media de 86,5 años: 58,7% de mujeres. La puntuación media del MNA®-SF fue de 8,9, estando el 20,0% sin riesgo nutricional, el 48,2% en riesgo nutricional y el 31,7% con malnutrición. Mediante la VGS, el 22,1% estaban bien nutridos, el 54,7% moderadamente desnutridos y el 23,2% gravemente desnutridos. El acuerdo entre VGS y MNA®-SF fue bueno (kappa = 0,654; p < 0,001), clasificando correctamente al 78,5% de los participantes. La malnutrición se asoció a peor estado cognitivo, mayor discapacidad, peor deambulación y niveles menores de proteínas totales, albúmina, colesterol y transferrina. Los pacientes con malnutrición según el MNA®-SF presentaron una mortalidad ajustada mayor que la de los bien nutridos (HR: 1,80; IC 95%: 1,01-3,20), igual que aquellos con VGS de C frente a los de A (HR: 1,66; IC 95%: 0,96-2,86). Los pacientes con VGS de B (OR: 1,42; IC 95%: 1,04-1,96) y C (OR: 1,73; IC 95%: 1,18-2,54) presentaron mayor riesgo ajustado de estancia hospitalaria prolongada frente a los bien nutridos. Los pacientes con malnutrición según el MNA®-SF presentaron mayor riesgo ajustado de estancia hospitalaria prolongada (OR: 1,59; IC 95%: 1,09-2,33) frente a los bien nutridos. Conclusiones: el riesgo nutricional y la malnutrición son muy frecuentes en los mayores hospitalizados en una UGA y se asocian con mayor mortalidad y estancias más prolongadas.

COVID-19 outbreak in long-term care facilities from Spain. Many lessons to learn.

BACKGROUND/OBJECTIVES: To analyze mortality, costs, residents and personnel characteristics, in six long-term care facilities (LTCF) during the outbreak of COVID-19 in Spain. DESIGN: Epidemiological study. SETTING: Six open LTCFs in Albacete (Spain). PARTICIPANTS: 198 residents and 190 workers from LTCF A were included, between 2020 March 6 and April 5. Epidemiological data were also collected from six LTCFs of Albacete for the same period of time, including 1,084 residents. MEASUREMENTS: Baseline demographic, clinical, functional, cognitive and nutritional variables were collected. 1-month and 3-month mortality was determined, excess mortality was calculated, and costs associated with the pandemics were analyzed. RESULTS: The pooled mortality rate for the first month and first three months of the outbreak were 15.3% and 28.0%, and the pooled excess mortality for these periods were 564% and 315% respectively. In facility A, the percentage of probable COVID-19 infected residents were 33.6%. Probable infected patients were older, frail, and with a worse functional situation than those without COVID-19. The most common symptoms were fever, cough and dyspnea. 25 residents were transferred to the emergency department, 21 were hospitalized, and 54 were moved to the facility medical unit. Mortality was higher upon male older residents, with worse functionality, and higher comorbidity. During the first month of the outbreak, 65 (24.6%) workers leaved, mainly with COVID-19 symptoms, and 69 new workers were contracted. The mean number of days of leave was 19.2. Costs associated with the COVID-19 in facility A were estimated at € 276,281/month, mostly caused by resident hospitalizations, leaves of workers, staff replacement, and interventions of healthcare professionals. CONCLUSION: The COVID-19 pandemic posed residents at high mortality risk, mainly in those older, frail and with worse functional status. Personal and economic costs were high.
