Gómez Tovar LO, Henao-Castaño ÁM. Effectiveness of nursing intervention to reduce delirium in adult critically ill - A protocol for a randomized trial. Contemp Clin Trials Commun 2022; 31:101042. [PMID: 36579130 PMCID: PMC9791593 DOI: 10.1016/j.conctc.2022.101042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 11/04/2022] [Accepted: 11/27/2022] [Indexed: 12/23/2022] Open
Abstract
The incidence of delirium in intensive care patients remains high, and its consequences have a high negative impact on patients, their families, health care teams, and society in general. Because delirium can lead to increased hospital stay, increased days on mechanical ventilation, increased risk of adverse events, increased memory loss and even increased mortality. However, some factors that precipitate delirium can be modified to reduce its presence and duration through non-pharmacological measures. Thus, the present protocol seeks to establish the theoretical and methodological background to develop and test nursing interventions to reduce delirium in adult patients hospitalized in the intensive care unit. For this reason, it is based on the theoretical elements of delirium and a nursing theory, called the Dynamic Symptoms Model (DSM), to understand the phenomenon and how nursing knowledge can be used to intervene. Thus, a nursing intervention proposal is proposed based on the DSM and scientific evidence, and a methodological design of a randomized controlled clinical trial type with parallel groups, which allows measuring the effectiveness of the designed interventions, following methodological and ethical rigor and with adequate control of biases.

Abstract
OBJECTIVE To understand the experiences in nursing care in the prevention and treatment of delirium in people hospitalized in intensive care units. METHODOLOGY Hermeneutic phenomenological qualitative study. The selection of participants was by intentional sampling: seven nursing assistants and eight nurses. Theoretical saturation was achieved. The phenomenological interview was applied to collect data from a central question and the analysis was carried out following the approaches of Heidegger's hermeneutical circle. RESULTS Four significant themes emerged from the analysis: (1) delirium prevention, (2) pharmacological treatment, (3) non-pharmacological treatment, and (4) barriers to non-pharmacological treatment. These themes were accompanied by 35 interrelated units of meaning: in the first theme, the most repetitive units were communication, orientation, and family bonding; in the second was the use of pharmacological treatment only in the acute phase; in the third was the modification of the environment according to the patient's preference (where the family is a priority and strategies that provide cognitive and social stimulation can be reinforced), and in the fourth was the work overload for the nursing team. CONCLUSIONS The experiences of the nursing team in the prevention and treatment of delirium in critically ill patients highlight that communication allows an approach to the patient as a human being immersed in a reality, with a personal history, needs and preferences. Therefore, family members must be involved in these scenarios, as they can complement and support nursing care.

Abstract
Delirium is a manifestation of brain injury or acute and generalized dysfunction of the upper cerebral cortical processes. In this way, it is important to analyze delirium more broadly as a symptom to understand and intervene taking into account that it is manifesting the presence of brain lesions whose consequences are deleterious to the neurological performance of patients. This article is intended to present a comprehensive approach of delirium analyzed from a symptom perspective and from theoretical and conceptual structure, such as the Dynamic Symptoms Model, specific to the nursing practice. A literature review related to delirium and components of Dynamic Symptoms Model was carried out. We searched the MEDLINE, ScienceDirect, SciELO, and Scopus databases using the terms Delirium, Intensive Care Units, Nursing, and Risk Factor. The existing literature provides evidence of the antecedents, experience, interventions, interactions, and consequences of delirium, which are components of the Model. Thus, the analysis from the Dynamic Symptoms Model perspective bears relevance and contributes to the understanding and approach of delirium.

Abstract
BACKGROUND Delirium is associated with high mortality after cardiac surgery. However, evidence on the epidemiology of delirium in patients with acute decompensated heart failure (ADHF) is limited. This study aimed to assess the incidence and prognostic impact of delirium in patients with ADHF. METHODS This single-center prospective observational study enrolled 132 consecutive patients with ADHF. We utilized the Diagnostic and Statistical Manual of Mental Disorders, fifth edition and classified the patients into two groups according to the presence or absence of delirium. The primary endpoint was 90-day all-cause mortality. The prognostic impact and risk factors of delirium were evaluated using multivariable Cox and logistic regression analyses, respectively. RESULTS The median patient age was 83 (interquartile range, 75-87) years. Approximately 51.5% were men. Delirium occurred in 36 (27.3%) patients, and hyperactive delirium was the most frequent type (86.1%). The 90-day all-cause mortality was higher in the patients with delirium than in those without (21.6% versus 3.9%, log-rank p = 0.002). Delirium was associated with higher mortality with an adjusted hazard ratio of 6.8 (95% confidence interval, 1.1-42.6, p = 0.042). The risk factors associated with delirium included advanced age, male sex, higher clinical frailty scale score, and dementia. CONCLUSIONS Delirium was associated with a higher 90-day all-cause mortality in the older adult patients with ADHF. Hyperactive delirium was the most common subtype.

World Neurosurg 2020; 140:e129-e139. [PMID: 32376378 DOI: 10.1016/j.wneu.2020.04.195] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Revised: 04/24/2020] [Accepted: 04/26/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Postoperative delirium (POD) describes a multifactorial disease process occurring after surgery. However, few studies have focused on patients undergoing brain tumor resection, and its influencing factors are unclear. METHODS We performed a 1-year, single-center, cross-sectional, retrospective survey at Huashan Hospital. Patients were screened using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), Confusion Assessment Method, and Richmond Agitation Sedation Scale by trained bedside nurses. Perioperative data were collected using demographic and disease-related questionnaires. The primary outcome measures were the incidence of POD and subtype of POD. Independent predictors of POD were estimated from multivariate logistic regression models, and receiver operating characteristic analysis was used to compare the predictive performance of the models. RESULTS Of the 916 patients included in the study, 893 were analyzed. The overall incidence was 14.78%, 67 had hyperactive delirium (50.76%), 55 had hypoactive delirium (41.67%), and 10 had mixed delirium (7.57%). Age, sex, working status, tobacco use history, comorbidities, physical restraint, axillary temperature (>38.5°C), electrolyte disturbances, duration of anesthesia, pathologic diagnosis, tumor site, length of disease, and duration of operation were risk factors for POD. Conversely, saddle area mass was a protective factor. Age, tobacco use history, electrolyte disturbances, physical restraint, and duration of operation were included in the model. CONCLUSIONS POD is harmful to patients undergoing brain tumor resection, increasing length of stay in the intensive care unit and hospitalization costs. Intraoperative factors and postoperative factors, in addition to older age and tobacco use history, are associated with POD.

Abstract
PURPOSE Use systematic review methodology to summarize risk factors and outcomes for each delirium subtype (hypoactive, hyperactive and mixed) in an adult ICU population. MATERIALS AND METHODS We searched the MEDLINE, Embase, CINAHL, SCOPUS, Web of Science and PsycINFO databases from database inception until August 13, 2018, with no restrictions. RESULTS Of 9635 abstracts, 20 studies were included. Older age was not associated with any delirium subtype in 4/7 (57%) studies. Sex was not associated with any delirium subtype in 4/4 (100%) studies. Mortality was consistently associated with hypoactive delirium in 4/7 (57%) studies. The evidence supporting the association of APACHE-II score, mechanical ventilation, length of stay, duration of delirium and removal of tubes were inconsistent across studies. CONCLUSIONS Although included studies reported on many subtype-specific risk factors and outcomes, heterogeneity in reporting and methodological quality limited the generalizability of the results and the evidence for many subtype-specific risk factors or outcomes is inconsistent across studies. Standardized methodology and the creation of a universal template for collecting data in ICU delirium studies are essential moving forward; helping to identify subtype-specific risk factors or outcomes and strengthen the association of potential risk factors or outcomes.

Abstract
INTRODUCTION Frailty is a multidimensional syndrome in which multiple small physiological deficits accumulate gradually, resulting in a loss of physiological reserve and adaptability, putting a patient that is exposed to a stressor at a higher risk of adverse outcomes. Both pre-frailty and frailty are associated with poor patient outcomes and higher healthcare costs. The effect of a prehabilitation programme and standard care on the quality of recovery in pre-frail and frail patients undergoing elective cardiac surgery will be compared. METHOD AND ANALYSIS A single-centre, superiority, stratified randomised controlled trial with a blinded outcome assessment and intention-to-treat analysis. Pre-frail and frail patients awaiting elective coronary artery bypass graft, with or without valvular repair/replacement, will be recruited. 164 participants will be randomly assigned to either prehabilitation (intervention) or standard care (no intervention) groups. The prehabilitation group will attend two sessions/week of structured exercise (aerobic and resistance) training, supervised by a physiotherapist, for 6-10 weeks before surgery with early health promotion advice in addition to standard care. The standard care group will receive the usual routine care (no prehabilitation). Frailty will be assessed at baseline, hospital admission and at 1 and 3 months after surgery. The primary outcomes will be participants' perceived quality of recovery (15-item Quality of Recovery questionnaire) after surgery (day 3), days at home within 30 days of surgery and the changes in WHO Disability Assessment Schedule 2.0 score between baseline and at 1 and 3 months after surgery. Secondary outcomes will include major adverse cardiac and cerebrovascular events, psychological distress levels, health-related quality of life and healthcare costs. ETHICS AND DISSEMINATION The Joint CUHK-NTEC Clinical Research Ethics Committee approved the study protocol (CREC Ref. No. 2017.696 T). The findings will be presented at scientific meetings, in peer-reviewed journals and to study participants. TRIAL REGISTRATION NUMBER ChiCTR1800016098; Pre-results.
