UWL: Food, Appetite and Environment (2009)
To determine the effects of dysphagia on selected social and psychological aspects of the quality of life of patients and to explore the relationship between the psychological handicaps of the condition and the frequency of diagnosis and treatment.
Patients were included only if they were able to understand and answer questions and regularly experienced one or more of the following subjective dysphagia-related symptoms:
- food sticking in the throat and/or choking on food
- persistent cough or sore throat
- inability to swallow liquids
- loss of appetite
- mild throat discomfort
- pain when swallowing
- heartburn and/or acid regurgitation
- Any respondent suffering from only loss of appetite or mild throat discomfort was excluded
- Any respondent who was suffering from severe dementia was excluded on the basis that they were unable to answer questions reliably
Recruitment
European nursing homes and clinics were located through directories and databases on the Internet, with the assistance of local healthcare professionals, public servants, and a network of regional physicians from the European Study Group on Dysphagia. Between July and August 1999, patients with dysphagia were selected from 37 nursing homes and clinics in Europe.
- The UK group was drawn from nursing homes and clinics/hospitals in the Manchester area
- The French group was drawn from nursing homes and hospitals in the region of Toulouse and Maine-et-Loire
- The German group was drawn from nursing homes in the Munich area
- The Spanish group was drawn from nursing homes around Madrid
Design: Cross-Sectional Study
Blinding used (if applicable): not applicable
Intervention (if applicable)
- Patients with dysphagia were interviewed using an established questionnaire developed by Gustafsson and Tibbling

Other Findings
Over 50% of patients (range 42% - 60%) claimed that they were "eating less" with 44% (range 36% - 49%) reporting weight loss during the preceding 12 months.
40% of patients acknowledged receiving a confirmed diagnosis of dysphagia; only 32% acknowledged receiving professional treatment for it.
Most people with dysphagia believe their condition to be untreatable, only 39% of the sufferers believed that their swallowing difficulties could be treated.
84% of patients felt that eating should be an enjoyable experience but only 45% actually found it so.
41% of patients stated that they experienced anxiety or panic during mealtimes.
Over 1/3 (36%) of patients reported that they avoided eating with others because of their dysphagia.
1/3 of patients needed personal assistance while eating.
In a large elderly population that might accept dysphagia as an untreatable part of the aging process, clinicians need to be aware of the adverse effects of dysphagia on self-esteem, socialization, and enjoyment of life. Careful questioning should assess the impact of the condition on each patient's life, and patients should be educated on their choices for treatment in the context of any coexisting illness. Awareness of the condition, diagnostic procedures and treatment options must be increased in society and among the medical profession.
In conclusion, the social and psychological impact of dysphagia is severe and the condition is underdiagnosed in European hospitals and clinics. Increased recognition by health care professionals in all countries to the possibility of dysphagia in patients and an understanding of treatment options in the context of comorbid conditions will relieve suffering and improve quality of life in many patients. The authors recommend that healthcare resources be allocated to the training of healthcare professionals and to providing management and treatment options.
