[Long-term care level as a predictor of a poor outcome in elderly patients with pneumonia].

AIM: To determine factors associated with physical decline and a poor prognosis after hospitalization in physically dependent elderly patients with acute pneumonia. METHODS: The subjects included 112 geriatric patients (86.8±5.5 years old) with acute pneumonia consecutively admitted to an inpatient unit of Geriatric Medicine, Kyorin University Hospital in the period from April 2012 to March 2013. All patients were generally treated with broad-spectrum antibiotics according to nursing- and healthcare-associated pneumonia (NHCAP) guidelines. The patients' baseline severity of pneumonia was evaluated according to the A-Drop score and their physical dependency was assessed according to the JABC score before and after admission. RESULTS: The patients were categorized into the community acquired pneumonia group (CAP) (n=29) and NHCAP group (n=83). The patients in the NHCAP group had a longer hospital stay (NHCAP vs. CAP: 33 vs. 21 days, p=0.02), higher A-Drop scores (2.88±0.80 vs. 2.45±0.87 points, p=0.02) and were more frequently diagnosed with aspiration pneumonia (89.2% vs. 42.9%, p<0.0001) than those in the CAP group. Three patients in the CAP group (10.3%) and 13 patients in the NHCAP group (15.7%) died during their hospital stay (p=0.69). Although the rest of the patients were successfully treated for pneumonia, their physical dependency progressed after admission in both groups (p<0.0001). After adjusting for age, gender and the JABC score before admission, NHCAP (risk ratio against CAP: 6.2, 95% CI 1.2-32.2, p=0.03) and a serum albumin lower than 2.5 g/dl (RR: 7.8, 95%CI 1.7-35.7, p<0.01) were significantly associated with the progression of physical dependency after admission. CONCLUSIONS: The diagnosis of NHCAP is a risk factor for the progression of physical dependency. Therefore, palliative care may be an optional approach for frail patients.

Accelerated cognitive decline after the COVID-19 pandemic in a community population of older persons with cognitive impairment: A 4-year time series analysis in the Tokyo Metropolis area.

AIM: The coronavirus disease 2019 (COVID-19) pandemic has led to lifestyle restrictions and might be associated with long-term changes in cognitive function. The aim of the present study was to elucidate the overall effect of the COVID-19 pandemic on the cognitive trajectory of a cohort of patients with cognitive impairment. METHODS: We enrolled 160 patients who had been making regular visits to a medical center for dementia. Cognitive function was assessed based on changes in scores on the Mini-Mental State Examination before and during the COVID-19 pandemic throughout a 4-year period. The trajectory of cognitive decline was determined by carrying out a time series analysis using a state-space model. RESULTS: Crude analysis showed that the Mini-Mental State Examination scores decreased from 20.9 ± 4.4 points (mean ± SD) at the time of the initial cognitive assessments to 17.5 ± 5.6 points at the time of the final assessments, and the decline rate was 1.15 ± 1.78 points per year (P < 0.0001). The time series analysis showed an accelerated cognitive trajectory after the COVID-19 outbreak, and the average decline in the Mini-Mental State Examination scores was 0.46 points (95% confidence interval 0.034-0.91) per year before the COVID-19 pandemic, and a steeper decline of 1.87 points (95% confidence interval 1.34-2.67) per year after the outbreak. CONCLUSIONS: The COVID-19 pandemic accelerated the rate of cognitive decline in patients with cognitive impairment fourfold in comparison with before the pandemic. Specific strategies designed for cognitively older people in the "new normal" will reconcile both requirements, reducing the risk of infection, and maintaining their physical and psychological well-being.
