Nursing microtheory in the prevention of delirium in older adult in the intensive care unit. / Microteoría de enfermería en la prevención del delirium en personas mayores en la unidad de cuidados intensivos.

OBJECTIVE: to describe a microtheory for nursing care in the prevention of delirium in older adult in the intensive care unit. METHOD: prescriptive theoretical research, based on substruction. Roy's Adaptation Model constructs were deduced and data from the phenomenon of nursing care in the prevention of delirium in older adult in intensive care were induced, based on an integrative literature review. RESULTS: the microtheory has a theoretical and operational system and a model of care. In the theoretical system, Roy's focal and contextual stimulus constructs were used. From them, the concepts of focal and contextual care and the variable adaptive response to prevention were elaborated. From the relational statements, four axioms, two postulates, eight propositions and an epistemic assumption were elaborated. TWO EMPIRICAL INDICATORS WERE ESTABLISHED IN THE OPERATING SYSTEM: the Confusion Assessment Method for Intensive Care Units and the demographic/clinical history of the older adult. Subsequently, two transformational statements, four hypotheses and the model of care represented in figure were produced. CONCLUSION: the microtheory produced prescribes care in the prevention of delirium in older adult in intensive care, through a construct of interest to nursing, and allows interceptions for the development of instruments that guide nursing activities.

Intervención de enfermería para reducir incidencia y duración del delirium en personas en cuidados intensivos  / Nursing Intervention to Reduce Incidence and Duration of Delirium in Patients in Intensive Care

Objetivo: determinar la efectividad de la intervención de enfermería basada en el Modelo de Síntomas Dinámicos (MSD) y en evidencia científica, frente al cuidado cotidiano, para la reducción de la incidencia y duración del delirium en personas en cuidados intensivos. Método: se emplearon dos fases, diseño y evaluación de la intervención. El diseño siguió las recomendaciones de Sidani desde el enfoque teórico con aplicación del MSD y desde el enfoque empírico con una revisión sistemática. La evaluación de la intervención se realizó con un ensayo clínico aleatorizado de grupos paralelos doble ciego. La muestra fueron 213 personas en UCI. El análisis empleó estadística analítica, paramétrica y no paramétrica. Resultados: se diseñó la intervención denominada Dynamic Delirium (DyDel) con 10 cuidados y 33 actividades. Los cuidados partieron de los componentes fisiológico, psicológico, spiritual y social, ambiental, experiencia y trayectoria del MSD. Las actividades de cada cuidado surgieron de la evidencia científica. Al probar la intervención se halló que la incidencia y duración del delirium fueron significativamente menor en el grupo intervención frente al grupo control (incidencia 5,6% Vs. 14,8%, respectivamente, (p=0.037)) (duración 0.07±0.308 Vs. 0.34±1.28, respectivamente (p=0.016)). El grupo intervención también logró más cantidad de días con dolor leve y sin uso de inmovilizaciones físicas. Conclusión: la intervención DyDel, basada en el MSD y en evidencia científica, fue multicomponente, no farmacológica y vincula a la familia, y fue efectiva para reducir el delirium en personas en UCI. Se comprobó que el conocimiento propio de enfermería mejora la práctica. (AU)

Objective: to determine the effectiveness of a nursing intervention based on the Dynamic Symptom Model (DSM) and scientific evidence, versus daily care, in reducing the incidence and duration of delirium in intensive care patients. Method: two phases were used, design and evaluation of the intervention. The design followed Sidani's recommendations from the theoretical approach with the application of the DSM and the empirical approach with a systematic review. The evaluation of the intervention was carried out with a randomized clinical trial of parallel groups, double-blind. The sample consisted of 213 ICU patients. The analysis used analytical, parametric and nonparametric statistics. Results: the intervention called Dynamic Delirium (Dydel) was designed with ten care and 33 activities. Care was based on the physiological, psychological, spiritual and social, environmental, experience and MSD trajectory components. The activities for each care were derived from scientific evidence. When testing the intervention, it was found that the incidence and duration of delirium were significantly lower in the intervention group versus the control group (incidence 5.6% vs 14.8%, respectively, (p=0.037)) (duration 0.07±0.308 vs 0.34±1.28, respectively (p=0.016)). The intervention group also achieved more days with mild pain and without the use of physical immobilizations. Conclusion: the DyDel intervention, based on the DSM and scientific evidence, was multicomponent, non-pharmacological and linked to the family, and was effective in reducing delirium in ICU patients. It was proven that nursing knowledge improves practice. (AU)

Postoperative Cardiovascular Surgery Delirium: Interrater Agreement Between Nurses and Clinical Nurse Specialist and Factors Associated With Prevalence.

PURPOSE: The aims of this study were to examine interrater agreement of delirium between clinical nurses and a clinical nurse specialist, determine delirium subtype prevalence, and examine associated patient, procedure, and hospital factors. DESIGN: A descriptive cross-sectional design and a convenience sample of nurses and patients on progressive care units were used in this study. METHODS: Clinical nurse specialist data were collected on a case report form, and clinician and patient data were obtained from electronic databases. Interrater agreement of delirium prevalence was assessed by κ statistic, and logistic regression models were used to determine patient factors associated with delirium. RESULTS: Of 216 patients, 23 had delirium; clinical nurses identified fewer cases than the clinical nurse specialist: 1.8% versus 10.7%; κ agreement, 0.27 (0.06, 0.49). By delirium subtype, hypoactive delirium was more frequent (n = 10). Factors associated with delirium were history of cerebrovascular disease (odds ratio [95% confidence interval], 2.8 [1.01-7.7]; P = .044), history of mitral valve disease (odds ratio [95% confidence interval], 0.31 [0.09-0.90]; P = .041), and longer perfusion time (odds ratio [95% confidence interval], 1.7 [1.1-2.7]; P = .016). One factor was associated with hypoactive delirium, longer perfusion time (odds ratio [95% confidence interval], 2.2 [1.3-4.2]; P = .008). CONCLUSIONS: Because clinician-clinical nurse specialist delirium agreement was low and hypoactive delirium was common, clinical interventions are needed.

The Impact of Nursing Delirium Preventive Interventions in the ICU: A Multicenter Cluster-randomized Controlled Clinical Trial.

Rationale: Delirium is common in critically ill patients and is associated with deleterious outcomes. Nonpharmacological interventions are recommended in current delirium guidelines, but their effects have not been unequivocally established. Objectives: To determine the effects of a multicomponent nursing intervention program on delirium in the ICU. Methods: A stepped-wedge cluster-randomized controlled trial was conducted in ICUs of 10 centers. Adult critically ill surgical, medical, or trauma patients at high risk of developing delirium were included. A multicomponent nursing intervention program focusing on modifiable risk factors was implemented as standard of care. The primary outcome was the number of delirium-free and coma-free days alive in 28 days after ICU admission. Measurements and Main Results: A total of 1,749 patients were included. Time spent on interventions per 8-hour shift was median (interquartile range) 38 (14-116) minutes in the intervention period and median 32 (13-73) minutes in the control period (P = 0.44). Patients in the intervention period had a median of 23 (4-27) delirium-free and coma-free days alive compared with a median of 23 (5-27) days for patients in the control group (mean difference, -1.21 days; 95% confidence interval, -2.84 to 0.42 d; P = 0.15). In addition, the number of delirium days was similar: median 2 (1-4) days (ratio of medians, 0.90; 95% confidence interval, 0.75 to 1.09; P = 0.27). Conclusions: In this large randomized controlled trial in adult ICU patients, a limited increase in the use of nursing interventions was achieved, and no change in the number of delirium-free and coma-free days alive in 28 days could be determined. Clinical trial registered with www.clinicaltrials.gov (NCT03002701).

Delirium in adult patients in intensive care: nursing interventions.

BACKGROUND: Delirium is a neuropsychiatric syndrome of high incidence in the critically ill patient. It is characterised by changes in acute attention and cognition, has a multifactorial aetiology and has a negative impact on the patient's clinical situation and future quality of life. Prevention of delirium and early identification can reduce associated morbidity and mortality. Consequently, it is vital that intensive care unit (ICU) nurses perform targeted patient monitoring to identify acute cognitive changes. OBJECTIVE: To identify nursing interventions directed at the prevention and management of delirium in adult patients in ICU. METHOD: A scoping review was undertaken based on the principles recommended by the Joanna Briggs Institute. RESULTS: Seven studies were selected for inclusion. Non-pharmacological and pharmacological nursing interventions were identified. CONCLUSION: The interventions identified were predominantly aimed at the prevention of delirium. The training of nurses and wider clinical team in preventing and identifying this syndrome is crucial.

A narrative review of preventive measures for postoperative delirium in older adults.

Postoperative delirium (POD) is an acute neurological condition associated with changes in cognition and attention and disorganised thinking. Although delirium can affect patients from any age group, it is common in older patients and could lead to a longer hospital stay and a higher risks of mortality. This article presents findings from a literature review that identifies various strategies used by health professionals globally to prevent POD. A database search resulted in 25 articles that met the inclusion criteria. Thematic analysis and coding were used to combine recurrent ideas that emerged from the literature. Three themes were identified: early identification and screening, modifiable risk factors, and preventive interventions. Further research focusing on education and improving awareness about POD among nurses is essential.

Preventing, identifying and managing delirium in nursing homes and acute settings.

Older people, particularly those in nursing homes, are vulnerable to delirium, which is a condition characterised by confusion. This article outlines the risk factors, prevention, identification and management of delirium in older people in nursing homes and acute settings. It uses a case study approach to encourage nurses to consider the challenges faced in these settings and how they could address delirium. The article also details the multicomponent interventions that can be used for prevention, as well as the available delirium assessment tools, with a focus on selecting tools based on the person's health status and the healthcare setting.

A comprehensive search identified publications on the topics of delirium; early mobility; communication; palliative care; tele-intensive care unit; care bundle implementation; and prevention, detection, and early management of infection. The evidence is summarized for each of these topics, as well as other research, with suggestions and guidance for end users.

Implementing a Rapid, Two-Step Delirium Screening Protocol in Acute Care: Barriers and Facilitators.

BACKGROUND/OBJECTIVES: An effective and efficient protocol for delirium identification is needed to improve health outcomes for older adults and reduce healthcare costs. This study describes the barriers and facilitators related to the implementation of the ultra-brief confusion assessment method (UB-CAM), a rapid two-step delirium identification protocol (ultra-brief screen, followed by CAM in positives), field tested with hospitalized older adults (70+). DESIGN: A qualitative descriptive design using observational data collection and brief semi-structured interviews. SETTINGS: An urban academic medical center and a community teaching hospital. PARTICIPANTS: Participants included 50 physician hospitalists, 189 registered nurses, and 83 nursing assistants (NAs). MEASUREMENTS: Field researchers guided by a modified multi-level implementation framework, collected observational data as participants administered the UB-CAM (n = 767). Thematic analysis was conducted on five observational categories: structural, organizational, patient, clinician, and innovation. Field notes and brief semi-structured interviews (n = 231) with clinicians, explored the utility, acceptability, and feasibility of the protocol, and supplemented the observations. RESULTS: The UB-CAM was generally positively received by all three clinician types. Six themes describe barriers and/or facilitators to implementing the UB-CAM: (1) physical setting and milieu; (2) practice environment; (3) integrating into role; (4) adaptive techniques; (5) patient responses; and (6) systematic assessment. The composition and interaction of the six themes determined if the theme was expressed as a barrier or facilitator, affirming the importance of context when implementing system-level delirium screening. CONCLUSION: This is one of the first studies to test a two-step process for delirium identification, and to involve NAs in screening, and the findings demonstrate overall support from clinicians for delirium identification, and describe the need for a multifaceted, contextualized, and systemic approach to implementation and evaluation of delirium screening.

Developing a dementia care leaders' toolkit for older patients with cognitive impairment.

A recent review of the progress that has been made in meeting the government's Challenge on Dementia 2020 detailed the variability, and in some cases suboptimal quality, of hospital care for people with dementia. The review also identified the need for improvements in assessing the individual needs of people with dementia while in hospital, including their emotional and social needs. This article focuses on the development and implementation of an evidence-based toolkit to improve the hospital care of older patients with cognitive impairment, including dementia and/or delirium. The toolkit's focus is on optimising the patient experience of people with cognitive impairment who have been admitted to hospital. The toolkit also promotes the importance of person-centred care and communication skills.

Are common delirium assessment tools appropriate for evaluating delirium at the end of life in cancer patients?

OBJECTIVES: The objectives of this study are to investigate how many advanced cancer patients became unconscious or non-communicative after pharmacological treatment for delirium, and to explore whether existing delirium assessment tools can successfully evaluate its severity at the end of life. METHODS: This was a secondary analysis of a registry study that examined the efficacy and safety of antipsychotics for advanced cancer patients with delirium. A total of 818 patients were recruited from 39 specialized palliative care services in Japan. The severity of delirium was measured using the Richmond Agitation-Sedation Scale-Palliative care version, the Delirium Rating Scale-Revised-98 (DRS-R-98), and the Nursing Delirium Screening Scale (Nu-DESC) on Day 3. Data from 302 patients with motor anxiety with an Agitation Distress Scale score ≥2 on Day 0 were analyzed for this study. The patients were categorized into four treatment response groups: complete response (CR: no agitation and fully communicative), partial response (PR: no/mild agitation and partially communicative), unconscious/non-communicative (UC), and no change (NC). RESULTS: On Day 3, 29 (10%; 95% confidence intervals [CI], 7-13) and 2 (1%; 95% CI, 0-2) patients became unconscious and non-communicative, respectively. Forty-four patients were categorized as CR, 97 as PR, 31 as UC, and 96 as NC. The scores of the DRS-R-98 and Nu-DESC in the UC group were rated higher than patients in the NC group were. CONCLUSIONS: A considerable number of cancer patients with delirium became unconscious or non-communicative. Existing delirium assessment tools may be inappropriate for measuring the severity of delirium in end-of-life.

Assessment and Management of Delirium in Critically Ill Veterans.

BACKGROUND: Delirium is a complex syndrome prevalent in the intensive care unit. It has been associated with significant morbidity including distress, longer hospital stays, prolonged cognitive impairment, and increased mortality. OBJECTIVE: To describe a nurse-led interdisciplinary quality improvement initiative to increase nurses' knowledge of delirium, documentation of delirium assessment, and patient mobility. METHODS: Sixty-seven nurses in medical and surgical intensive care units were required to attend an interactive education program on delirium assessment and management. Scores on tests taken before and after the education program were used to evaluate knowledge. Medical records and bedside rounds were used to validate Confusion Assessment Method for the Intensive Care Unit documentation and interventions. Descriptive statistics were used to describe changes over time. A delirium resource team composed of nurses, physicians, and therapists provided didactic education paired with simulation training and bedside coaching. Mobility screening tests and computer templates guided assessments and interventions. RESULTS: Documentation of the Confusion Assessment Method improved from less than 50% to consistently 99%. Mobilization in the surgical intensive care unit increased from 90% to 98% after intervention. Days of delirium significantly decreased from 51% before intervention to 31% after intervention (χ12=7.01, P = .008). CONCLUSIONS: The success of this quality improvement project to enhance recognition of delirium and increase mobility (critical components of the pain assessment, breathing, sedation choice, delirium, early mobility, and family education bundle) was contingent on nursing leaders hip, interdisciplinary team collaboration, and interactive education.

Post-stroke delirium risk factors, signs and symptoms of onset and outcomes as perceived by expert nurses: A focus group study.

BACKGROUND: Higher rates of delirium have been reported among patients with acute stroke. However, poorly modifiable risk factors have been documented to date while sign and symptoms capable of early detecting its onset and outcomes in this specific population have been largely neglected. The aim of this study was to emerge nurses' clinical knowledge and experiences regarding post-stroke delirium (a) risk factors, (b) signs and symptoms of delirium onset, and (c) outcomes. METHOD: A qualitative study based upon focus groups have been performed on 2019 and here reported according to the COnsolidated criteria for REporting Qualitative research. A purposeful sample of 28 nurses was invited to participate in focus groups at two Italian hospitals, and 20 participated. A semi-structured question guide was developed; all focus groups were audio recorded and then transcribed verbatim. Two researchers independently analysed, coded and categorised the findings according to the main research question. A member checking with ten nurses was also performed to ensure rigour. RESULTS: Four risk factors emerged (a) at the individual level; (b) associated with previous (e.g., dementia) and the current clinical condition (stroke), (c) associated with the nursing care delivered, and (d) associated with the hospital environment. In their daily practice, nurses suspect the onset of delirium when some motor, verbal or multidimensional signs and symptoms occur. The delirium episodes affect outcomes at the individual, family, and at the system levels. CONCLUSIONS: In a field of research in need of study, we have involved expert nurses who shared their tacit knowledge to gain insights regarding risk factors, early signs and symptoms of delirium and its outcomes to address future directions of this research field.

Managing delirium in terminally ill patients: perspective of palliative care nurse specialists.

Delirium occurs frequently at end of life. Palliative care clinical nurse specialists (CNSs) are involved in community palliative care provision. Many patients prefer being cared for at home, yet managing delirium in this setting presents unique challenges, potentially resulting in emergency hospital or hospice admission. We examined the experiences and practice of palliative care CNSs managing delirium in the community; 10 interviews were undertaken. Data were analysed using the framework approach. Challenges to delirium management in the community included limited time with patients, reliance on families and access to medications. Assessment tools were not used routinely; time limited visits and inconsistent retesting were perceived barriers. Management approaches differed depending on CNSs' previous delirium education. Strategies to prevent delirium were not used. Community delirium management presents challenges; support surrounding these could be beneficial. Routine assessment tool use and delirium prevention strategies should be included in further education and research.

Multimodal Education Program to Improve Nurses' Knowledge and Confidence on Delirium Recognition in a Surgical-Trauma Intermediate-Care Setting.

BACKGROUND: High incidence of delirium in hospitalized patients has been reported in the United States and is significantly associated with increased morbidity and mortality. The lack of knowledge and confidence in performing delirium assessment (KCDA) has led to significant underrecognition of delirium by nurses regardless of evidence-based education intervention. OBJECTIVE: The purpose of this study was to determine the effectiveness of a multimodal educational program (MEP) to enhance nurses' KCDA. METHODS: A MEP including an online didactic with a video-simulation and 1:1 bedside coaching with delirium screening (DS) was conducted in the surgical intermediate-care unit of an academic medical center. A quasi-experimental pre- and post-test design was used. RESULTS: Of 23 nurses, the majority were <41 years old (73.9%) and had at least a bachelor of science in nursing degree (78.3%) with <6 years of experience (60.9%). The overall KCDA scores and the performance of DS improved significantly after the MEP (p < .001). A positive correlation was noted between the changes of the KCDA scores (p = .009). CONCLUSIONS: The MEP demonstrated improvement in nurses' KCDA. The MEP should focus on an individualized learning approach with a targeted patient population, using current delirium screening tools. IMPLICATIONS FOR NURSING: Educational programs are recommended in either an orientation or continuing education program on nursing units. This is also recommended for use in other academic centers that encompass similar clinical settings and could possibly be considered for use in other disease processes.
