Objective: Delirium is usually under-detected and under-treated. Understanding the barriers of this issue among nurse
practitioners is crucial in order to deliver effective educational strategies for delirium care. The objectives of the present study were to examine knowledge and attitudes regarding delirium among them, and associated factors.
Materials and Methods: This is a cross-sectional study. The survey was conducted from October 1 to December 31, 2016.
Questionnaires were developed to evaluate the participants’ knowledge and attitudes regarding delirium. These were then
sent to the nurse practitioners who worked with and cared for older patients of Srinagarind Hospital, Thailand. The completed questionnaires were returned to the researchers.
Results: A total of 407 out of 600 questionnaires were returned (67%). The median score on questions pertaining to
knowledge of delirium was 58.6%. Most respondents were knowledgeable about the prevalence and risk factors of delirium (71.4%). They displayed modest knowledge regarding its importance (62.5%), treatment, and prevention (60%), but showed poor knowledge regarding diagnosis (0%) of the condition. Factors associated with number of correct answers were increased years of practice (adjusted odds ratio [AOR] 1.04) and experience in geriatrics (AOD 3.21). The majority of respondents agreed that delirium was a normal condition for hospitalized older patients and had little confidence in their ability to detect and treat this condition.
Conclusion: Nurse practitioners displayed misperceptions and a lack of knowledge, as well as misperceptions regarding
delirium. Work experience and experience in geriatric medicine were significantly associated with better scores.
