Association of Oral Health with Frailty, Malnutrition Risk and Functional Decline in Hospitalized Older Adults: A Cross-Sectional Study.

BACKGROUND: Poor oral health is known to be associated with adverse outcomes, but the frequency and impact of poor oral health on older adults in the acute inpatient setting has been less well studied. OBJECTIVES: We examined the association between oral health, frailty, nutrition and functional decline in hospitalized older adults. DESIGN: Retrospective cross-sectional study. SETTING AND PARTICIPANTS: We included data from 465 inpatients (mean age 79.2±8.3 years) admitted acutely to a tertiary hospital. METHODS: We evaluated oral health using the Revised Oral Assessment Guide (ROAG), frailty using the Clinical Frailty Scale (CFS), malnutrition risk using the Nutritional Screening Tool (NST) and functional status using a modified Katz Activities of Daily Living (ADL) scale. We examined cross-sectional associations of oral health with frailty, malnutrition risk and functional decline on admission, followed by multivariate logistic regression models evaluating the association between poor oral health and the aforementioned outcomes. RESULTS: 343 (73.8%), 100 (21.5%) and 22 (4.7%) were classified as low, moderate and high risk on the ROAG, respectively. Poorer oral health was associated with greater severity of frailty, functional decline on admission and malnutrition risk. Abnormalities in ROAG domains of voice changes, swallowing difficulty, xerostomia, lips and tongue appearance were more frequently present at greater severity of frailty. Poor oral health was associated with frailty [odds ratio (OR): 1.76, 95% confidence interval (CI) 1.05-2.97; P=0.034]; malnutrition risk [OR: 2.76, 95% CI 1.46-5.19, P=0.002] and functional decline [OR: 1.62, 95% CI 1.01-2.59, P=0.046]. CONCLUSIONS: Poor oral health is significantly associated with frailty, malnutrition risk and functional decline in older inpatients. Oral health evaluation, as part of a comprehensive geriatric assessment may be a target for interventions to improve outcomes. Further research including longitudinal outcomes and effectiveness of specific interventions targeted at oral health are warranted in older adults in the inpatient setting.

Singapore Clinical Practice Guidelines For Sarcopenia: Screening, Diagnosis, Management and Prevention.

OBJECTIVES: To present the local evidence and final recommendations of the Clinical Practice Guidelines workgroup convened by the Chapter of Geriatricians and the Society for Geriatric Medicine Singapore. The aim is to develop contextualized evidence-based recommendations that facilitate adoption of the Asian Working Group for Sarcopenia (AWGS) 2019 consensus into current practice in Singapore. METHODS: The workgroup drew upon the AWGS'2019 consensus, updated literature review of Singapore studies till 31 Dec 2020, and evidence from recent systematic reviews. From 40 local studies included for data extraction, we constructed evidence tables organized as: definition and epidemiology; diagnosis and evaluation; and treatment and intervention. Twenty recommendations - case-finding, diagnosis, treatment, prevention, research - were developed, and graded for strength and quality using the GRADE approach. Consensus from an expert panel(N=23) was achieved after two rounds of the modified Delphi process. RESULTS: The local prevalence of sarcopenia among community-dwelling older adults ranged from 13.6% to 25%. Most studies adopted the AWGS'2019 and AWGS'2014 criteria. Reported case finding tools include SARC-F, calf circumference (CC) and SARC-CalF. Gender-specific AWGS cut-offs for appendicular skeletal mass were used to define low muscle mass. Different protocols and dynamometers were used to assess handgrip strength, whilst gait speed and 5-times chair stand were commonly used to assess physical performance. RECOMMENDATIONS: We conditionally recommend a case-finding approach in at-risk older adults using validated case-finding tools. Screen-positive individuals should be assessed for 'possible sarcopenia' and underlying causes. For diagnosis, we conditionally recommend using the AWGS'2019 algorithm, and dual-energy X-ray absorptiometry when necessary to determine low lean mass for a confirmatory diagnosis of sarcopenia. For treatment, we strongly recommend resistance-based exercises and conditionally recommend a quality protein-rich diet/protein supplementation, with Vitamin D supplementation for insufficiency (<30 micrograms/L). For prevention, we recommend regular resistance-based physical activity and adequate protein intake (≥1.0g/kg bodyweight). We encourage more research to address local evidence gaps.
