Impact of the Severity of Alzheimer's Disease on the Quality of Life, Activities of Daily Living, and Caregiving Costs for Institutionalized Patients on Anti-Alzheimer Medications in Japan.

ABSTRACT:

Background

Alzheimer's disease (AD) increases societal costs and decreases the activities of daily living (ADL) and quality of life (QoL) of the affected individuals.

Objective

We assess the impact of AD severity on ADL, QoL, and caregiving costs in Japanese facilities for the elderly.

Methods

Patients with AD in facilities for the elderly were included (47 facilities, N = 3,461). The QoL, ADL, and disease severity of patients were assessed using Barthel Index (BI), EuroQoL-5D-5L (EQ-5D-5L), and Mini-Mental State Examination (MMSE), respectively. Annual caregiving costs were estimated using patients' claims data. The patients were subcategorized into the following three groups according to the MMSE score: mild (21≤MMSE≤30), moderate (11≤MMSE≤20), and severe (0≤MMSE≤10). Changes among the three groups were evaluated using the Jonckheere-Terpstra test.

Results

Four hundred and one participants were on anti-AD medicines, of whom 287 (age: 86.1±6.4 years, 76.7% women) in the mild (n = 53, 84.0±6.9 years, 71.7%), moderate (n = 118, 86.6±5.9 years, 76.3%), and severe (n = 116, 86.6±6.5 years, 79.3%) groups completed the study questionnaires. The mean BI and EQ-5D-5L scores for each group were 83.6, 65.1, and 32.8 and 0.801, 0.662, and 0.436, respectively. The mean annual caregiving costs were 2.111, 2.470, and 2.809 million JPY, respectively. As AD worsened, the BI and EQ-5D-5L scores decreased and annual caregiving costs increased significantly.

Conclusion

AD severity has an impact on QoL, ADL, and caregiving costs.

Project description:ObjectiveTo systematically review the literature on the metabolic costs of activities of daily living (ADL) in persons with a lower limb amputation (LLA).Data sourcesA literature search was undertaken in the Pubmed, Embase, CINAHL, CENTRAL, and PsycINFO databases using keywords and synonyms for LLA, metabolic costs, and ADL. The last search was performed on November 29th, 2017.Study selectionStudies were included if they met the following 2 criteria: participants were adults with a (unilateral or bilateral) LLA and metabolic costs were measured while participants performed a physical activity or ADL.Data extraction and synthesisData of 1,912 participants from 61 studies were included in the systematic review and meta-analysis. The studies used different terms to describe metabolic costs. Participants were recruited in different settings, relatively healthy, with few comorbidities. Limited data were available on metabolic costs of other activities than walking with a prosthesis. A linear mixed model analysis was performed based on the means reported, with study as unit of analysis and test results of different groups and measurement conditions as repeated measures within the unit of analysis. Predictors entered in the analysis were e.g. level and reason of amputation, age, weight, and height. During walking, oxygen consumption (ml O2/kg/min) and heart rate (beats/min) increased with a higher walking speed and a more proximal amputation. Additionally, oxygen consumption was determined by the interaction terms walking speed x amputation level and walking speed squared. Heart rate was determined by the interaction term walking speed squared.ConclusionDuring walking, oxygen consumption (ml O2/kg/min) and heart rate (beats/min) increased with a higher walking speed and a more proximal amputation. Data on metabolic costs of other activities were limited. The poor quality of the studies and the relatively healthy participants limited generalizability of the results of the meta-analysis.
