Background and study aims
The natural clinical course of advanced dementia has been reported in a few studies. They often experience problems with eating and drinking, but the reason for this has not been clarified. The causes for any individual patient can be unclear, because most of those patients are nearing the end-of-life and are not likely to be assessed adequately. However, the prognosis of these patients can be improved by giving them treatments (or interventions) that help them to be able to eat. In Japan, it is recommended that elderly patients have a comprehensive geriatric assessment (CGA). This has been shown to improve their functional status (that is, improve their ability to perform normal daily activities) and prognosis for some diseases (for example, chronic heart failure and pneumonia). This study investigates whether an intervention based on CGA can also help patients suffering from eating and swallowing disorder of the elderly with dementia (ESDED).A special ESDED team has been set up called the "Eating and Swallowing Assessment Team (ESAT)" which consists of medical doctors, dentists, dental hygienists, pharmacists, nurses, speech therapists, physical therapists, occupational therapists, dieticians and certified care workers. This team has developed a new system to examine ESDEDs using the original clinical pathway (CP). This CP involves assessments by each specialist and integration of their findings followed by diagnosing the etiology (cause) of ESDED in each patient. Based on the diagnosis, ESAT designs various interventional methods (treatments) and passes this information to the medical staff treating the ESDED. This study looks at whether this medical care system based on CGA improves the ability of eating and prognosis of the patients with ESDEDs.

Who can participate?
Elderly patients aged over 70 with cognitive impairment (difficulties in thinking and memory), who need to be treated with artificial hydration and/or nutrition.

What does the study involve?
Each participant has a CGA developed by the ESAT. For the first two days this involves assessing the patients various functions (physical, cognitive, chewing, swallowing, and sensory), collecting their past medical and medication history, and obtaining detailed information of their eating problems. The team perform a physical and dental examination, urine and blood examination, chest X-ray, electrocardiogram, and magnetic resonance imaging of the brain of each patient. In addition, the behavior and reaction of each patient during nursing at dinner is observed and a list of the problems that they are having swallowing is drawn up. On the third day, a video-endoscopic examination of the patients swallowing is done, after which the ESAT decides the cause of the problems each patient has with eating. This is based on all the data that has been collected. The ESAT then plans further assessment or examination in order to identify the details of the etiology for each patient. On days 4 and 5, the ESAT perform the planned assessment or examinations and makes the final diagnosis for the etiology of the eating problem experienced by each patient. Based on the diagnosis, ESAT proposes various interventional strategies to the medical staff who treat the ESDED.

What are the possible benefits and risks of participating?
The participants might be able to be withdrawn from AHN. However, they might have a risk of receiving an excessive assessment or intervention, which would be unnecessary for their original medical care.

Scientific titleThe effect of comprehensive assessment with multi-disciplinary interventions for eating and swallowing disorders in the elderly with dementia; non-randomized, historical controlled, interventional study
Study objectivesThe comprehensive assessment with multi-disciplinary interventions could determine the details of etiologies of eating and swallowing disorders in the elderly patients with dementia, which would help the improvement of the functional status of the eating leading to better overall survival of those patients.
Ethics approval(s)The Institutional Review Board of Nanto Municipal Hospital, 21/03/2013, ref: # 664
Health condition(s) or problem(s) studiedEating and swallowing disorder of the elderly with dementia (ESDED)
InterventionThe subjects receive comprehensive geriatric assessment (CGA) through the original clinical pathway with multi-disciplinary interventions followed by the individualized therapeutic interventions according to the assessment of the etiology of their eating problems.
Intervention typeMixed
Primary outcome measure1. Recovery rate (RR): RR represents the rate of participants who become free from AHN by taking enough amounts of nutrition and water orally for at least 7 days (longer than 7 days). If they cannot be withdrawn from AHN before discharge from the hospital, they are considered to be failed
2. AHN free survival (AHNFS): AHFNS represents the survival rate of participants who have become free from AHN. AHFNS is assessed by Kaplan Meier method, in which each participant is estimated to reach the endpoint if the participant is dead or becomes dependent on AHN. The survival rate is measured one year after withdrawal from AHN
Secondary outcome measuresThe overall survival (OS) after onset of ESDED: OS is assessed by Kaplan Meier method, in which each participant’s endpoint is death. The survival rate is measured one year after the onset of ESDED

IPD sharing plan summaryAvailable on request
Publication and dissemination planThe trialists will collect all the data of outcomes until July 2016. Therefore, they will write and submit the article on this study in August or September 2016.
IPD sharing planThe datasets generated during and/or analysed during the current study are/will be available upon request from Dr Masahisa Arahata. The dataset including both intervention group and historical group can be obtained from today, and this will be stored as long as possible (at least 5 years from publication). The dataset consists of personal data (patient no., allocated group, age, sex, baseline characteristics, outcomes, other clinical data, and so on) stored in a Microsoft Excel file suitable for EZR. All personal data was completely anonymized. EZR (Saitama Medical Center, Jichi Medical University, Saitama, Japan) is a graphical user interface for R (The R Foundation for Statistical Computing, Vienna, Austria), which is used for statistical analysis in many studies. In order to obtain the dataset of the trial and use for other studies, another ethics approval (from the trialists' institution and/or about the new study) will be necessary. A fee may be required for preparation of a new ethics approval.
