Predictive Factors Associated with Oral Intake Ability in Gastrostomy Patients Under Long-Term Care.

OBJECTIVE

To determine the physical indicators associated with oral intake status and swallowing function in gastrostomy patients under long-term care.

DESIGN

Cross-sectional study.

SETTING

Thirty-one hospitals that perform gastrostomy insertion, replacement and management.

PARTICIPANTS

A total of 117 respondents from 31 hospitals in Japan underwent gastrostomy tube replacement and management between September 2012 and January 2014. Each participant underwent a gastrostomy at least 6 months prior to the study, and received long-term care either at home, a care facility, or a hospital.

MEASUREMENTS

We conducted a questionnaire survey at Japanese hospitals and used the data obtained from 117 respondents for analysis. The survey was conducted using a questionnaire form that collected information about the following items: oral intake status, sex, age, disease history, number of days elapsed since gastrostomy, residence status, modified Rankin Scale score, consciousness, oral hygiene status, articulation and phonation, voluntary saliva swallow, Modified Water Swallow Test, and Food Test.

RESULTS

Results revealed significant differences in modified Rankin Scale scores, sputum production, articulation and phonation, and voluntary saliva swallowing between patients who were orally fed and those who were not. Moreover, sputum production and voluntary saliva swallowing were strongly associated with oral intake status. Finally, sputum production, articulation and phonation, and voluntary saliva swallowing were strongly associated with swallowing function test results.

CONCLUSION

Results from this study suggested that sputum production, articulation and phonation, and voluntary saliva swallowing could be used as indicators for estimating oral intake status and swallowing function in gastrostomy patients under long-term care.
