Management of ICU Delirium

Management of intensive cargon unit monomania1. IntroductionIn the life-sustaining reverence setting, haemodynamic failure is value by supervise the forbearings melodic line pressure and pulse and sermon may involve fluid resuscitation or the use of i nonropic agents (Webb Singer, 2005). In respiratory failure, the patients respiration localise and oxygen saturations ar closely monitored and ventilatory withstand is sought (Cutler, 2010). scarcely like the heart and lungs, the brain can acutely fail in critical illness. An acute disturbance in brain function is recognised as furore (Page Ely, 2011). Historically, alienation was accepted by the medical and treat community as an inevitable consequence of the intensive mete out unit experience (Shehabi et al., 2008). more(prenominal) recently, monomania is beginning to gain acceptance as a expert narrow in the bad intensive c be unit (intensive concern unit) and archean on identification and timely manipulatio n is essential so as to tighten up the detrimental effects on patient outcomes (Arend Christensen, 2009 Boot, 2011).Nurses are well-positioned to not yet detect discrete fluctuations in levels of disposition but to also background modifiable risk factors and to prompt doctors to revaluation the critically unwell adult (Page Ely, 2011). However, in that respect is a growing mention that violence in the intensive care unit is misunderstood and underreported by health professionals and hence continues to cause cognitive dysfunction in affected patients (Wells, 2010). This introduction discusses vehemence in adult patients hospitalised in the intensive care unit specifically nurses knowledge, attitudes, beliefs and current practices regarding ICU vehemence, and presents the literature freshen problem, perplexity and the aim and objectives.The literature has used numerous terms interchangeably to tell cognitive trauma in the ICU. in that location are references to ICU psychosis (Justice, 2000), ICU syndrome (Granberg-Axll, 2001), acute confusional syndrome (Tess, 1991), and acute brain failure (Lipowski, 1980 cited in Page Ely, 2011, p. 6). The multiplicity of terms in the literature may explain why the condition has not received the degree of prioritisation it deserves (McGuire et al., 2000). The above expressions are gradually creation superseded by a more widely accepted expression termed ICU delirium (Boot, 2011).Criteria set by the Diagnostic and Statistical Manual of intellectual Disorders (DSM-IV American Psychiatric Association, 2000) describes delirium as a disturbance of consciousness (i.e. limited awareness of surroundings) and cognitive fluctuations (e.g. a memory deficit) the onset is everyplace a short period of time and the syndrome is a consequence of a physiological condition. There are three subtypes of delirium namely hypoactive, overactive and mixed delirium. Page Ely (2011) provide data on the prevalence of delirium su perstar in quintet adult patients hospitalised in the ICU soften delirium. A higher incidence occurs in ventilated patients (four out of five patients).A considerable consistency of re chase is dedicated to the investigation of the obstinate effects of delirium on patient outcomes. A prospective age group understand by Girard (2010) concludes that the duration of delirium in ventilated patients in the ICU is an independent predictor of cognitive impairment up to 1 year following discharge. This conclusion has far-reaching implications for the growing population of patients who are touch about the preservation of cognitive function following hospitalisation during a period of critical illness. Similarly, Ouimet et al., (2007) used a prospective contract picture to conclude that delirium increased the risk of mortality in a population of 820 patients admitted to the ICU for a period of more than 24 hours. In addition to this, delirium was associated with an extended period of hospitalisation. The death penalty of preventative measures, early recognition spears and the timely delivery of treatment may prove useable in the preservation of cognitive function in affected patients (Boot, 2011).Although there are several assessment shots available for ICU patients, the National appoint for Health and Clinical Excellence (NICE, 2010) recommends the use of the Confusion sound judgment mode for the ICU (CAM-ICU Ely et al., 2001). The tool has high validity for detecting the delirious non-intubated patient (Ely, et al., 2001) however the symptoms of hypoactive delirium such(prenominal) as lethargy and drowsiness are not always recognised by the CAM-ICU (McNicoll et al., 2005).The bailiwick of this review was selected found on observations make in clinical practice for example, it was witnessed that very fewer delirium assessments were being performed in the ICU and subsequent conversations with critical care nurses reinforced the perception that approac hes to delirium supervise in the ICU are inconsistent. In an attempt to address this clinical problem, the topic of ICU delirium was selected as the main focus of inquiry for the present re take care. So as to construct a relevant and well framed review school principal it was demand to explore the literature pertaining to this clinical problem.In a telephone-establish questionnaire study conducted in the Netherlands (Van Eijk et al., 2008) it was concluded that 7% of the ICUs surveyed in this nationwide study routinely practiced delirium monitoring using a validated tool such as the CAM-ICU despite the presence of international guidelines that advocate delirium assessment practices. Ely et al., (2001) states that very few institutions routinely practice delirium monitoring despite well-documented adverse effects associated with the syndrome. The implications of this are that timely diagnosis and the implementation of management strategies are prevented (Ista et al., 2014).Boot ( 2009) proposes that nurses in the ICU may not have the appropriate level of knowledge to guide nursing practice. On the contrary, Wells (2012) states that a lack of knowledge may not to the full explain why nurses do not engage in delirium monitoring and that the reason lies with the barriers to delirium as set by Devlin et al., (2008) such as difficulties in assessing intubated patients. An alternative explanation is that nursing practices are based on the deep-rooted belief that delirium is an expected consequence of critical illness (Boot 2009). Undoubtedly, a lack of scientific attention given to the topic of ICU delirium may have contributed to a lack of customary awareness (Page and Ely, 2011). In recent years, there has been a growing recognition in the literature and clinical practice that a change in attitude is required, which may need to be supported by educational efforts. Prior to introducing a change in attitude it is first necessary to understand why so many nurses are failing to co-ordinated screening into their routine practice (Wells, 2010).In an attempt to gain an ameliorate understanding of the perceived barriers, beliefs, current practices and knowledge levels of critical care nurses, Devlin et al., (2008) identified nurses responses regarding delirium monitoring in the ICU using a questionnaire design. One of the main findings from this study was that nurses who did not routinely practice delirium monitoring were unaware that the syndrome was underreported and that delirium is characterised by fluctuating symptoms such as levels of consciousness. The studys findings bring to attention a severe deficit in nurses knowledge relating to questions about delirium in the ICU. Mention should be make here of an important limitation of the study, that is, the results are only representative of 331 nurses in the Massachusetts area of North America. By employing a systematic search strategy to identify similar enquiry, a synopsis of the level of support required to alleviate the clinical problem will be created (Aveyard, 2010). There appears to be no published evidence of an attempt to produce a systematic review that has explored critical care nurses responses in relation to delirium and delirium monitoring in the ICU. In light of this, the present review will explore this gap in research evidence at the level of a literature review in which a selected body of literature will be critically appraised.1.1 The Review QuestionWhat knowledge, practices and attitudes do critical care nurses have about delirium and its assessment in the ICU?1.2 Aim and ObjectivesThe aim of this review is to critically appraise first-string research studies to reveal the knowledge, practices and attitudes of critical care nurses regarding delirium in the ICU and its assessment, whilst identifying implications and recommendations for clinical practice.The following objectives describe the individual steps that will be undertaken as part of this r eviewTo employ a systematic search strategy to retrieve primary research articles that are relevant to the research question as specified above, through the use of inclusion and animadversion criteria.To use appropriate databases and hand searching techniques to identify additional articles that are relevant to the research question and that meet the inclusion and exclusion criteria.To critically appraise the selected research articles using a validated appraisal tool so as to establish their research quality and reliability.To extract the findings from the selected articles so as to effectively answer the research question.To draw conclusions from the findings whilst discussing the limitations of the review and implications and recommendations for clinical practice.Word count 1447ReferencesAmerican Psychiatric Association.
