Analysis of clinical outcomes in elderly patients with impaired swallowing function.

Japan is the world's leading aging society, and increasing medical expenses for elderly people is an urgent issue. Since aspiration pneumonia in elderly people with impaired swallowing function is a huge problem in Japan, their expected long-term clinical course should be clarified. Accordingly, we collected data from 991 elderly (≥75 years old) patients whose swallowing function was evaluated by Kitasato Institute Hospital's speech therapists (January 1, 2010 to December 31, 2017). We analyzed the relationship between swallowing function and the subjects' long-term prognosis. To clarify the prognostic factors of patients with dysphagia, we obtained their clinical information (age, gender, activities of daily living, nutritional status, availability of alternative feeding pathways such as percutaneous endoscopic gastrostomy, and cognitive function). We confirmed 372 death cases and stratified the cases into three groups using Fujishima's swallowing ability grade, which is used to predict elderly people's real-world life expectancy. Results showed the median survival days were 331 and 952 days in Groups I (Grades 1-3, n = 308) and II (Grades 4-6, n = 153), respectively, whereas the median survival days for Group III (Grades 7-10, n = 530) could not be calculated. We conducted a multivariate analysis using the Cox proportional hazards model with Group I, which revealed that initial grade and percutaneous endoscopic gastrostomy were significant prognostic factors for the subjects' long-term survival. Nevertheless, further discussion is necessary, particularly to determine advanced care planning regarding indications for alternative feeding pathways in elderly patients with severe dysphagia, since percutaneous endoscopic gastrostomy could significantly prolong their survival.

Ultrasound-Guided Fine-Needle Aspiration in the Neck Region Using an Optical See-Through Head-Mounted Display: A Randomized Controlled Trial.

OBJECTIVES: The purpose of this study was to examine the feasibility of an optical see-through head-mounted display (OST-HMD) to improve ergonomics during ultrasound-guided fine-needle aspiration (FNA) in the neck region. METHODS: This randomized controlled study compared an OST-HMD with a normal ultrasound monitor during an ultrasound-guided FNA in the neck region. Patients with a neck tumor were recruited and randomized into one of two groups. Two practitioners performed ultrasound-guided FNA with or without the HMD, as indicated. An independent researcher measured the procedure time, the number and time of head movements, as well as the number of needle redirections. In addition, practitioners completed questionnaires after performing the FNA on each patient. RESULTS: In 93% of the sessions with the OST-HMD, practitioners performed ultrasound-guided FNA without turning the patients' heads. There was no difference in procedural time and number of needle redirections between the two groups. Results from the questionnaire revealed not only good wearability and low fatigue, but also the practitioners' preference for the HMD. CONCLUSIONS: The OST-HMD improved the practitioners' ergonomics and can be adopted for performing ultrasound-guided interventional procedures in clinical settings.
