Association between swallowing function, activities of daily living, and eating posture in patients with terminal cancer

For individuals facing a terminal cancer diagnosis, maintaining quality of life is paramount. A recent observational study sheds light on the often-overlooked connection between swallowing difficulties – known as dysphagia – and a patient’s ability to perform everyday activities.

Understanding the Link Between Swallowing and Daily Life

Researchers examined data from 201 patients admitted to a palliative care unit between November 2018 and April 2024 who were undergoing rehabilitation. The study focused on how swallowing function related to Activities of Daily Living (ADLs), which encompass essential self-care tasks, and eating posture.

Did You Know? The average age of the patients included in this study was 82.0 years, with a standard deviation of 10.8 years.

How Was the Study Conducted?

Patients were assessed using the Functional Oral Intake Scale (FOIS) to measure swallowing function and the Functional Independence Measure (FIM) to evaluate their ADLs. Eating posture – whether patients sat upright, in a chair, or with the bed elevated – was also recorded, along with their Palliative Prognostic Index (PPI). Patients were divided into two groups: those reliant on a feeding tube (FOIS scores of 1-3) and those still able to eat by mouth (FOIS scores of 4-7).

Key Findings of the Research

The study revealed a significant association between swallowing function and a patient’s ability to perform daily activities. Specifically, improved swallowing function correlated with higher scores on the FIM, indicating greater independence. The researchers found that for every one-point increase in swallowing function, there was a 3% increase in the modified FIM score (OR 1.03, 95% CI 1.01-1.05, P = 0.002), a 7% increase in the combined FIM score (OR 1.07, 95% CI 1.02-1.12, P = 0.002), and a 3% increase in the total FIM score (OR 1.03, 95% CI 1.01-1.05, P = 0.002). Approximately 26.4% of the patients studied were tube-dependent.

Expert Insight: This research underscores the importance of a holistic approach to palliative care. Addressing swallowing difficulties isn’t simply about nutrition; it’s about preserving a patient’s dignity and ability to engage in the activities that contribute to their overall well-being.

What Could This Mean for the Future?

Because this study used a cross-sectional design, it cannot definitively prove that improved swallowing causes greater independence in daily living. However, the findings suggest a strong relationship. Future research, potentially involving prospective studies that follow patients over time, could help establish a clearer understanding of this connection. This proves also possible that further investigation could explore the impact of different eating postures on swallowing function and ADLs.

Frequently Asked Questions

What is dysphagia?

Dysphagia is the medical term for swallowing dysfunction, or difficulty swallowing.

What is the Functional Oral Intake Scale (FOIS)?

The FOIS is a tool used to assess a patient’s ability to safely and effectively consume food and liquids by mouth, with scores ranging from 1 to 7.

What is the Functional Independence Measure (FIM)?

The FIM is a tool used to measure a patient’s level of independence in performing activities of daily living.
