Educational intervention on delirium assessment using confusion assessment method-ICU (CAM-ICU) in a general intensive care unit.

To assess intensive care unit nurses' knowledge of intensive care unit delirium and delirium assessment before and after an educational intervention. In addition, nurses' perception on the usefulness of a delirium assessment tool and barriers against delirium assessment were assessed as secondary objectives. Early identification of delirium in intensive care units is crucial for patient care. Hence, nurses require adequate knowledge to enable appropriate evaluation of delirium using standardised practice and assessment tools. This study, performed in Malaysia, used a single-group pretest-posttest study design to assess the effect of educational interventions and hands-on practices on nurses' knowledge of intensive care unit delirium and delirium assessment. Sixty-one nurses participated in educational intervention sessions, including classroom learning, demonstrations and hands-on practices on the Confusion Assessment Method-Intensive Care Unit. Data were collected using self-administered questionnaires for the pre- and postintervention assessments. Analysis to determine the effect of the educational intervention consisted of the repeated-measures analysis of covariance. There were significant differences in the knowledge scores pre- and postintervention, after controlling for demographic characteristics. The two most common perceived barriers to the adoption of the intensive care unit delirium assessment tool were "physicians did not use nurses' delirium assessment in decision-making" and "difficult to interpret delirium in intubated patients". Educational intervention and hands-on practices increased nurses' knowledge of delirium assessment. Teaching and interprofessional involvements are essential for a successful implementation of intensive care unit delirium assessment practice. This study supports existing evidences, indicating that education and training could increase nurses' knowledge of delirium and delirium assessment. Improving nurses' knowledge could potentially lead to better delirium management practice and improve ICU patient care. Thus, continuous efforts to improve and sustain nurses' knowledge become relevant in ICU settings.

Nursing Understanding and Perceptions of Delirium: Assessing Current Knowledge, Attitudes, and Beliefs in a Burn ICU.

The number of delirium days in hospitalized patients directly correlates with mortality and long-term cognitive dysfunction. Burn patients are at greater risk for delirium due to prolonged mechanical ventilation, high sedative and analgesic medication requirements, and the common need for multiple operations. Limited research exists on nurses' understanding and comfort using delirium screening tools and preventive interventions. A process improvement project was developed in a single, regional burn intensive care unit (BICU) with the goal of increasing RN staff awareness of delirium, delirium assessment, and preventive interventions. A 10-question survey was developed and administered to the BICU RN staff before and after the educational intervention. Both quantitative and qualitative data analyses were performed. Twenty-seven (38%) anonymous surveys were returned. In pre- and postintervention surveys, respondents agreed that nursing interventions were important in preventing delirium. Despite educational intervention, 26% of the respondents reported that a tool is not needed to identify delirium. Survey analysis indicated strong support for nonpharmacologic nursing interventions in preventing delirium as well as reducing pharmacologic interventions, especially benzodiazepines. Mechanical ventilation was perceived as a barrier to performing the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) in both pre- and postsurveys. Staff compliance with documenting CAM-ICU assessments increased and CAM-positive days decreased over the project timeline. Overall, BICU nurses' awareness and general knowledge about delirium increased and specific knowledge deficits were discovered. Continued education about the CAM-ICU tool is still needed; additionally addressing barriers within the structure of the unit to provide nurses more resources to properly assess and prevent delirium.

Intervention to improve intensive care nurses' knowledge of sedation assessment and management.

Sedation management is an integral component of critical care practice. It requires the greatest attention of critical care practitioners because it carries significant risks to patients. Therefore, it is imperative that nurses are aware of potential adverse consequences of sedation therapy and current sedation practice recommendations. To evaluate the impact of an educational intervention on nurses' knowledge of sedation assessment and management. A quasi-experimental design with a pre- and post-test method was used. The educational intervention included theoretical sessions on assessing and managing sedation and hands-on sedation assessment practice using the Richmond Agitation Sedation Scale. Its effect was measured using self-administered questionnaire, completed at the baseline level and 3 months following the intervention. Participants were 68 registered nurses from an intensive care unit of a teaching hospital in Malaysia. Significant increases in overall mean knowledge scores were observed from pre- to post-intervention phases (mean of 79·00 versus 102·00, p < 0·001). Nurses with fewer than 5 years of work experience, less than 26 years old, and with a only basic nursing education had significantly greater level of knowledge improvement at the post-intervention phase compared to other colleagues, with mean differences of 24·64 (p = 0·001), 23·81 (p = 0·027) and 27·25 (p = 0·0001), respectively. A repeated-measures analysis of variance revealed a statistically significant effect of educational intervention on knowledge score after controlling for age, years of work and level of nursing education (p = 0·0001, ηp (2) = 0·431). An educational intervention consisting of theoretical sessions and hands-on sedation assessment practice was found effective in improving nurses' knowledge and understanding of sedation management. This study highlighted the importance of continuing education to increase nurses' understanding of intensive care practices, which is vital for improving the quality of patient care.

Delirium assessment in intensive care units: practices and perceptions of Turkish nurses.

As delirium in intensive care unit (ICU) patients is a serious problem that can result in increased mortality and morbidity, routine delirium assessment of all ICU patients is recommended. The severity, duration and outcome of the syndrome are directly related to nurses' continuous assessment of patients for signs and symptoms of delirium. However, studies indicate that very few nurses monitor for delirium as a part of their daily practices. The aim of this study was to identify current practices and perceptions of intensive care nurses regarding delirium assessment and to examine the factors that affect these practices and perceptions. A descriptive, correlational study design was used. Data were collected from five Turkish public hospitals using a structured survey questionnaire. The study sample comprised 301 nurses who agreed to participate. Data were analysed using descriptive statistics. More than half of the nurses performed delirium assessments. However, the proportion of nurses who use delirium assessment tools was quite low. Almost all of the nurses perceived delirium as a problem and serious problem for ICU patients. The patient group least monitored for delirium was that of unconscious patients. Statistically significant differences were found in the proportion of nurses who assessed delirium symptoms and whose care delivery system was patient-centred and perceived delirium as a serious problem. While a majority of ICU nurses perceived delirium as a problem and serious problem, the proportion of those who perform routine delirium assessments was less. It was found that delirium assessment practices of nurses were affected from their perceptions of delirium and the implementation of patient-centred care delivery. It is essential to develop strategies to encourage ICU nurses to perform delirium assessments through the use of delirium assessment tools.
