Practicalities of Integrating Nutrition into Geriatric Care31 ottobre 2011
- Dysphagia and malnutrition are modifiable conditions that diminish patient quality of life and heighten morbidity, mortality, and costs.
- Call for systematic validated screening to enable early nutrition intervention
- Multi-disciplinary teams are best positioned to support patients
Vevey, Switzerland, October 2011 – The Nestlé Nutrition Institute organised several complimentary
educational sessions at the 7th European Union Geriatric Medicine Society (EUGMS) Annual Congress
in Malaga, Spain.
At the Nestlé Nutrition Institute Satellite Symposium, keynote speakers highlighted the benefits of
integrated management of dysphagia and malnutrition. A multidisciplinary panel of experts, chaired by
Professor Maurits Vandewoude, Head of the Geriatrics Dept, University of Antwerp (Belgium), outlined
the magnitude of the problem for the patient as well as for health care systems. The pathophysiologic
mechanisms leading to the development of oropharyngeal dysphagia along with the available methods
for screening, identifying and treating this under-diagnosed condition were also discussed. Professor
Vandewoude commented, “Earlier nutrition intervention coupled with systematic screening will allow
multi-disciplinary teams to more effectively manage these under-diagnosed conditions and reduce the
economic and societal burden of these treatable life-threatening conditions.”
Oropharyngeal dysphagia: A growing concern in health care
Professor Rebecca Leonard, Clinical Director of the Voice and Swallowing Centre, University of
California-Davis (USA), highlighted that unmanaged dysphagia can have severe health consequences
including malnutrition, dehydration, and aspiration pneumonia which is associated with increased
mortality1. She discussed how the swallowing mechanism changes with age and how otherwise
healthy older individuals can suffer from dysphagia due to acute illness or certain medications.
Professor Leonard noted, “Our studies have shown that older adults need longer swallowing time (25-
30%) and experience a reduced upper oesophageal opening”. Epidemiologic studies2, 3 suggest that 22% of over 50 year olds suffer from dysphagia, rising to nearly 40% in those over 60. In the US alone, of 77 million hospitalisations in 2004/5 the mortality rate associated with dysphagia was 13.7%. In addition, hospital stays were twice as long at an estimated cost of $547 million per year4.
Pathophysiology of oropharyngeal dysphagia in the older adult
Dr. Helena Bascuñana Ambrós, Director of Physical Medicine and Rehabilitation Dept, Sant Pau
University Hospital, Barcelona (Spain), further explored the pathophysiology of dysphagia among older
adults. She emphasised the nature of the oropharyngeal musculature; most of the muscle fibres being
Type II which are powerful but tire quickly, and she illustrated the positive effect that exercise can have
on reducing or reversing the atrophy in these muscles. Dr Bascuñana commented, “The optimal
intervention for older people with dysphagia is compensatory, rehabilitative, or a combination of both.”
She reported how her team has established a telemedicine rehabilitation program that makes use of the
internet to provide guided therapy to patients in their homes, to improve the cost-effectiveness of follow-
up care, and to avoid readmissions when their condition is not well-managed.
Dysphagia and malnutrition: From screening to treatment
Early identification of those at risk for dysphagia and malnutrition requires suitable screening tools for
these highly prevalent conditions among older people. Dr Rosa Burgos Peláez, Chief of the Nutritional
Support Unit, University Hospital Vall d’Hebron, Barcelona (Spain), focused on the need to consider the 2 of 2 sensitivity and specificity, and the ease of use when selecting a screening method. She presented the protocol used in her region for early screening and management of dysphagia and malnutrition among patients at-risk of these conditions. She reviewed in detail the screening tool for dysphagia, Eating Assessment Tool (EAT-10)5, an easy to perform test that is fast for patients to complete6, and how her team recently validated the Spanish version of this tool. The group found that the EAT-10 was easy to understand by over 95% of patients, quickly completed in less than 4 minutes, and useful to
differentiate those patients with dysphagia risk vs. a normal swallow7. Dr Burgos also discussed the use of the Mini Nutritional Assessment short form (MNA®-SF)8, a highly sensitive and specific method to screen for malnutrition in older adults. Both of these tools are provided by the Nestlé Nutrition Institute as part of their on-going support of clinicians to improve patient quality of life through science-based nutrition interventions. “These screening methods are easy to perform and enable initiation of nutritional intervention that improves clinical outcomes of malnourished patients and reduces costs associated with the condition, such as decreasing hospital stay (average reductions of 2 days or more) and readmissions (a 28% reduction)”, commented Dr Burgos9, 10.
Hands-on application of science-based nutrition solutions in geriatric care: A multi-disciplinary effort
The Nestlé Nutrition Institute11 also organised a workshop, which used a patient case study approach to illustrate the practicalities of integrating nutrition into geriatric care. Prof Frederico Cuesta Triana, geriatrician at Hospital Clinico San Carlo, Madrid (Spain), and Prof Stéphane M Schneider, Head of the Nutritional Support Unit in the Digestive Dept, Nice University Hospital (France), delivered a fully interactive session. The case showed the integration of nutrition screening and evidence-based decision making to determine the appropriate nutrition intervention. The participants’ knowledge of the ESPEN guidelines on enteral nutrition amongst older adults was tested alongside their awareness of the importance of protein and the effects of Vitamin D on the reduction of falls and fractures12. Data shows that a Vitamin D dose of >400 IU/d results in a 20% risk reduction of non-vertebral fractures13 and 700 IU/d results in a 23% reduction in fall risk14. Also discussed was data from a 2009 Cochrane review which demonstrated a 21% decrease in mortality in undernourished older adults when they are supplemented with Oral Nutritional supplements15. The workshop closed with consensus that early nutritional intervention can help prevent the downward spiral towards dependence which, associated with other co-morbidities, leads to a rapid decline in health, the need for institutionalisation and the associated economic and social burden.
