To improve assessment and management of pain in nonverbal older adults with dementia, an effective means of recognizing and evaluating pain in this vulnerable population is needed. The purpose of this review is to critically evaluate the existing tools used for pain assessment in this population to provide recommendations to clinicians. Ten pain assessment tools based on observation of behavioral indicators for use with nonverbal older adults with dementia were evaluated according to criteria and indicators in five areas: conceptualization, subjects, administration, reliability, and validity. Results indicate that although a number of tools demonstrate potential, existing tools are still in the early stages of development and testing. Currently, there is no standardized tool based on nonverbal behavioral pain indicators in English that may be recommended for broad adoption in clinical practice.
Time from admission to operation is a risk factor for preoperative delirium, whereas low BMI is an important risk factor for postoperative delirium in hip fracture patients. Cognitive impairment and indoor injury are independent risk factors for preoperative and postoperative delirium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
