Anorexia of aging: An international assessment of healthcare providers' knowledge and practice gaps

Abstract

BackgroundAnorexia of aging is a common geriatric syndrome that includes loss of appetite and/or reduced food intake, with associated undernutrition, unintended weight loss, sarcopenia, functional decline, loss of independence and other adverse health outcomes. Anorexia of aging can have multiple and severe consequences and is often overlooked by healthcare professionals (HCPs). Even more concerningly, clinicians commonly accept anorexia of aging as an inevitable part of ‘normal’ aging. The aim of this assessment was to identify current gaps in professional knowledge and practice in identifying and managing older persons with anorexia. Results may guide educational programmes to fill the gaps identified and therefore improve patient outcomes.MethodsThis international assessment was conducted using a mixed‐methods approach, including focus group interviews with subject matter experts and an electronic survey of practicing HCPs. The assessment was led by the Society on Sarcopenia, Cachexia and Wasting Disorders (SCWD) and was supported by in‐country collaborating organizations.ResultsA quantitative survey of 26 multiple‐choice questions was completed by physicians, dietitians and other HCPs (n = 1545). Most HCPs (56.8%) recognize a consistent definition of anorexia of aging as a loss of appetite and/or low food intake. Cognitive changes/dementia (91%) and dysphagia (87%) are seen as the biggest risk factors. Most respondents were confident to give nutritional (62%) and physical activity (59.4%) recommendations and engaged caregivers such as family members in supporting older adults with anorexia (80.6%). Most clinicians assessed appetite at each visit (66.7%), although weight is not measured at every visit (41.5%). Apart from the Mini‐Nutritional Assessment Short Form (39%), other tools to screen for appetite loss are not frequently used or no tools are used at all (29.4%). A high number of respondents (38.7%) believe that anorexia is a normal part of aging. Results show that treatment is focused on swallowing disorders (78%), dentition issues (76%) and increasing oral intake (fortified foods [75%] and oral nutritional supplements [74%]). Nevertheless, the lack of high‐quality evidence is perceived as a barrier to optimal treatment (49.2%).ConclusionsFindings from this international assessment highlight the challenges in the care of older adults with or at risk for anorexia of aging. Identifying professional practice gaps between individual HCPs and team‐based gaps can provide a basis for healthcare education that is addressed at root causes, targeted to specific audiences and developed to improve individual and team practices that contribute to improving patient outcomes.

Consequences of Anorexia of Aging in Hospital Settings: An Updated Review

“…Additionally, a lack of knowledge regarding the implications of anorexia of aging on health outcomes, alongside scarcity of evidence for management strategies to address the problem when identified, also hinders progress in routine clinical practice. 14,15 Given the high prevalence of anorexia in older hospital populations, it is important to understand appetite-related factors in this setting. The multi-dimensional nature of anorexia of aging and effects of environmental cues, also means that the syndrome should be considered in each setting, as findings may not translate from other cohorts.…”
