Non-pharmacological interventions to improve constipation amongst older adults in long-term care settings: A systematic review of randomised controlled trials

Constipation is a highly prevalent condition amongst older adults in long-term care settings and laxatives are not always the solution. We aimed to examine the characteristics and the effects of non-pharmacological interventions to improve constipation amongst older adults in long-term care settings. Eligible studies were identified using PubMed, CINAHL, Scopus, Web of Science, Cochrane and EMBASE (up to April 2019). We included 7 studies with a total of 657 patients. Five interventions improved the number of bowel movements (i.e. laxative tea, fermented oat drink, patient education, probiotics and multi-component intervention). The administration of probiotic capsules and fermented oat drinks also improved stool form. Auricular acupressure improved constipation symptoms and constipation-related quality of life. After appraising the trials' methodological quality and risk of bias, we cannot recommend any non-pharmacological interventions to improve constipation amongst older adults in long-term care settings until more robust studies have been conducted.
