Association between being at-risk of malnutrition and discontinued home medical care among older patients: a 1-year follow-up study.

BACKGROUND: Both malnutrition and at-risk of malnutrition are prevalent among older patients receiving home medical care. Discontinuation of home medical care usually occurs when an older patient is admitted to a hospital or nursing home or dies. This study aimed to assess prospective associations between nutritional status and discontinuation of home medical care in older patients. METHODS: Three hundred and thirty-three Japanese older patients receiving home-visit nursing care services were included in this study. Their nutritional status was assessed using the Mini Nutritional Assessment®-Short Form, and patients were classified into three groups (well-nourished, at-risk of malnutrition and malnourished). Outcomes were confirmed at the 1-year follow-up survey. Hazard ratios (HRs) and 95% confidence intervals (CIs) for discontinuation of home medical care based on nutritional status were calculated using a Cox proportional hazard model. Covariates included age, sex, living status, economic status, activities of daily living, comorbidities and dysphagia status. RESULTS: In total, 297 patients (median age: 84 years) were analysed. At baseline, 48.5% of the patients were at-risk of malnutrition and 18.9% were malnourished. During the observation period of 1 year, 27.6% patients discontinued their home medical care. In the adjusted model, the HR for discontinuation of home medical care among those at-risk of malnutrition was 2.44 (95% CI: 1.34-4.45) times than that of the well-nourished group, although the malnourished group was not significantly associated with discontinuation of home medical care (HR: 1.69, 95% CI: 0.77-3.72; referent: well-nourished). CONCLUSIONS: At-risk of malnutrition was associated with discontinuation of home medical care among older patients.

Scoring methods used in the dietary variety score survey to predict malnutrition among older patients receiving home care.

BACKGROUND: The dietary variety score (DVS), a simple dietary survey method for older adults, investigates the weekly frequency of consumption of the 10 food groups in Japan. The DVS is also associated with nutritional status. The original scoring method applied only to community-dwelling older adults, not to older patients receiving home care, who have little dietary variety. AIM: Using three different scoring methods for the DVS, we examined which method was most likely to reflect the nutritional status of older patients receiving home care. METHODS: This cross-sectional study was carried out on older patients receiving home care. Participant characteristics, the DVS (evaluated using three different scoring methods), and the Mini Nutritional Assessment-Short Form (MNA® -SF) survey were researched. A receiver operating characteristic (ROC) analysis was performed to find the cut-off value for the DVS. Multivariate analysis was performed, with malnutrition as the outcome, to investigate the extent to which the DVS is associated with malnutrition. RESULTS: We studied 317 participants. The DVS could produce significant ROC curves using modified scoring methods A and B (p = .028 and .042) with nutritional status as the outcome. Cut-off value, sensitivity and specificity were 30 points, 60.9% and 55.9% in modified scoring method A and 5 points, 79.1%, and 35.6% in modified scoring method B. Results of the multivariate logistic regression analysis, in Model 1 dysphagia (odds ratio [95% confidence interval]: 3.85 [1.70-8.71]) and the DVS of modified scoring method A (2.00 [1.11-3.62]) were significant independent factors. In Model 2, dysphagia (3.57 [1.58-8.07]) and the DVS based on modified scoring method B (2.36 [1.24-4.47]) were significant independent factors. CONCLUSIONS: Modified scoring method B was found to be most suitable for the dietary assessment of older patients receiving home care. IMPLICATIONS FOR PRACTICE: Even in the absence of registered dietitians, any care staff member who is involved in providing nursing services during home-visits is capable of administering a dietary survey, when using the easy DVS scoring method.

Lower dietary variety is a relevant factor for malnutrition in older Japanese home-care recipients: a cross-sectional study.

BACKGROUND: Nutritional status of the older people is affected by various life-style factors. Although dietary habit is one of the life-style factors, it is unknown which of older home-care recipients' dietary habits are associated with malnutrition. The purpose of this study was to examine the association of dietary variety, as an evaluation index for dietary habits, with malnutrition in Japanese older home-care recipients. METHODS: This cross-sectional study was conducted in a single city, Hyogo Prefecture, Japan between July and October 2016. Three hundred thirty-three community-dwelling older care recipients (aged 65 years or older who were receiving home-visit nursing care services) were enrolled. Their nutritional status (Mini Nutritional Assessment®-short form: MNA®-SF), dietary variety (Food frequency score [FFS]), socio-demographic characteristics (age, sex, marital status, etc.), health indicators (comorbidity [Charlson Comorbidity Index] and dysphagia status [Dysphagia Severity Scale]) were assessed. The participants were classified into two groups: malnourished (0-7 points) and non-malnourished (8-14 points), according to their MNA®-SF scores. Multivariate logistic regression analysis was used to examine the factors associated with malnutrition. RESULTS: A total of 317 participants were analyzed (118 men, 199 women, median age: 84 years). Compared to the fourth (highest) quartile of FFS, odds ratios (OR) (95% confidence intervals [CI]) of the third, second, and first (lowest) quartiles of FFS were 1.08 (0.42-2.80), 1.29 (0.56-2.98), and 2.30 (1.02-5.19), respectively (p for trend = 0.049). Higher Charlson Comorbidity Index score and the presence of dysphagia were also significantly associated with malnutrition (OR: 2.08, 95% CI: 1.08-4.00 and OR: 3.86, 95% CI: 2.08-7.17, respectively). CONCLUSION: Lower dietary variety was significantly associated with malnutrition in Japanese older home-care recipients.
