The quality of the studies in this systematic review varied. Although clinical practice recommendations were limited by the strength of evidence, probiotic interventions were effective in treatment and prevention of urogenital infections as alternatives or co-treatments. More good quality research is needed to strengthen the body of evidence needed for application by clinicians.

Background: Delirium in older adults is considered a medical emergency; it contributes to a cascade of functional decline and to increased mortality. Early recognition of delirium symptoms is critical to prevent these negative consequences. Family caregivers who are educated about delirium could partner with nurses and other healthcare professionals in early recognition of delirium symptoms. Before implementing such partnership models, it is important to examine the effectiveness of educating family caregivers about delirium.
