Abstract
Aim: The present study aimed to investigate the effectiveness of ultrasound（US）assessment of constipation and the treatment and care of patients with dementia with constipation by a healthcare team.
Methods: This retrospective observational study included 55 participants with dementia with constipation. The primary outcome was the improvement in spontaneous defecation based on the Bristol Stool Form Scale（BSFS）score. When we assessed defecation, the presence or absence of stools in the rectum was confirmed by US. The effectiveness of the support team interventions in achieving BSFS 3-5 points（normal stool）was evaluated using a generalized linear mixed-effects model.
Results: The results of this study showed that the odds of achieving BSFS 3-5（normal stools）were twice as high in the support team intervention group as in the no-intervention group（odds ratio［OR］: 2.03, 95% confidence interval:［1.23, 3.33］, p = 0.005）.
Conclusions: We indicated that the intervention for patients with dementia with constipation requires a professional team having knowledge regarding analysis of US imaging findings, and regarding dementia and constipation, and who can effectively plan treatment and care.
