Assessment of Delirium in the Intensive Care Unit: Nursing Practices And Perceptions

Assessment of Delirium in Intensive Care Unit Patients: Educational Strategies

BACKGROUND

Delirium is an acute brain dysfunction associated with poor outcomes in intensive care unit (ICU) patients. Critical care nurses play an important role in the prevention, detection, and management of delirium, but they must be able to accurately assess for it. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) instrument is a reliable and valid method to assess for delirium, but research reveals most nurses need practice to use it proficiently.

METHOD

A pretest-posttest design was used to evaluate the success of a multimodal educational strategy (i.e., online learning module coupled with standardized patient simulation experience) on critical care nurses' knowledge and confidence to assess and manage delirium using the CAM-ICU.

RESULTS

Participants (N = 34) showed a significant increase (p < .001) in confidence in their ability to assess and manage delirium following the multimodal education. No statistical change in knowledge of delirium existed following the education.

CONCLUSION

A multimodal educational strategy, which included simulation, significantly added confidence in critical care nurses' performance using the CAM-ICU. J Contin Nurs Educ. 2017;48(5):239-244.

The validity and reliability of the Arabic version of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU): A prospective cohort study

BACKGROUND

Accurate diagnosis for Arabic speaking critically ill patients suffering from delirium is limited by the need for a valid/reliable translation of a standardized delirium instrument such as the Confusion Assessment Method for the ICU (CAM-ICU).

OBJECTIVE

To determine the validity and reliability of the Arabic version of the CAM-ICU.

DESIGN

A prospective cohort study design was used to conduct the current study.

SETTINGS

Data collection took place in Geriatric, Emergency and Surgical intensive care units.

PARTICIPANTS

Fifty-eight adult patients met the inclusion criteria and participated in the study. Among the participants 22(38%) patients were on mechanical ventilation.

METHODS

After translating the CAM-ICU into Arabic language, the Arabic CAM-ICU was administered by two well-trained critical care nurses and compared with reference standard assessments by delirium experts using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM -IV-TR), along with assessment of severity of illness using Sequential Organ Failure Assessment (SOFA). Concurrent validity was assessed by calculating sensitivity, specificity and positive and negative predictive value (PPV and NPV) for the two Arabic CAM-ICU raters, where calculations were based on considering the DSM-IV-TR criterion as the reference standard. The convergent validity of the Arabic CAM-ICU was explored by comparing the Arabic CAM-ICU ratings and the total score of SOFA (severity of illness) and MMSE (cognitive impairment).

RESULTS

A total of 58 ICU patients were included, of whom 27 (47%) were diagnosed with delirium during their ICU stay via DSM-IV criteria. Interrater reliability for the Arabic CAM-ICU, overall and for mechanically ventilated patients assessed using Cohen's kappa (κ) were 0.82 and 1, respectively, p < 0.001. The sensitivities (95% CI) for the two critical care nurses when using the Arabic CAM-ICU compared with the reference standard were 81% (60%-93%) and 85% (65%-95%), respectively, whereas specificity (95% CI) was 81%(62%-92%) for both nurses. High sensitivity and specificity measures were also observed across subgroups; 100% for mechanically ventilated patients, 88% (60%-98%) and 79% (49%-94%) for those aged 65 years or older and 82% (56%-95%) and 75% (43%-93%) for those with SOFA scores at or above the median value.

CONCLUSIONS

The Arabic CAM-ICU appeared to be valid and reliable tool for diagnosing delirium. Future investigations may lead to a better understanding of the prevalence, predictors, and consequences of delirium among critically ill Arabic speaking patients.

Barriers to delirium assessment in the intensive care unit: A literature review

BACKGROUND

Delirium is a common syndrome that has both short and long-term negative outcomes for critically ill patients. Many studies over several years have found a knowledge gap and lack of evidence-based practice from critical care personnel, but there has been little exploration of the reasons for this.

AIM

To identify the perceived barriers to delirium assessment and management among critical care nurses.

METHOD

A literature review of published studies to examine barriers to effective delirium assessment using a comprehensive search strategy. Five relevant studies identified for review.

RESULTS

Few studies have investigated barriers to delirium assessment and management, but several themes reoccur throughout the literature. The perceived time consuming nature of the assessment tools is cited by many, as is the lack of medical prioritisation of results. Lack of education on delirium appears to be a significant factor and reinforces some of the stated misconceptions.

CONCLUSION

Many barriers exist to prevent effective assessment and management of delirium, but several of these are due to a lack of understanding or unfamiliarity with the condition and the assessment tools as well as lack of medical prioritisation of the results. Further research is needed on this topic.

Prevention, recognition and management of delirium in patients who are critically ill

Delirium is common in patients who are critically ill, often resulting in extended hospital stays and increased mortality and morbidity. There are several subtypes of delirium, which are often undiagnosed and untreated, resulting in suboptimal patient outcomes. This article examines delirium in patients in the intensive care unit, including its signs and symptoms, incidence, causes and subtypes. It outlines the assessment of delirium and the pharmacological and non-pharmacological interventions that can be used to manage the condition, as well as describing the optimal prevention measures.

Development and validation of an automated delirium risk assessment system (Auto-DelRAS) implemented in the electronic health record system

BACKGROUND

A key component of the delirium management is prevention and early detection.

OBJECTIVE

To develop an automated delirium risk assessment system (Auto-DelRAS) that automatically alerts health care providers of an intensive care unit (ICU) patient's delirium risk based only on data collected in an electronic health record (EHR) system, and to evaluate the clinical validity of this system.

DESIGN

Cohort and system development designs were used.

SETTING

Medical and surgical ICUs in two university hospitals in Seoul, Korea.

PARTICIPANTS

A total of 3284 patients for the development of Auto-DelRAS, 325 for external validation, 694 for validation after clinical applications.

METHODS

The 4211 data items were extracted from the EHR system and delirium was measured using CAM-ICU (Confusion Assessment Method for Intensive Care Unit). The potential predictors were selected and a logistic regression model was established to create a delirium risk scoring algorithm to construct the Auto-DelRAS. The Auto-DelRAS was evaluated at three months and one year after its application to clinical practice to establish the predictive validity of the system.

RESULTS

Eleven predictors were finally included in the logistic regression model. The results of the Auto-DelRAS risk assessment were shown as high/moderate/low risk on a Kardex screen. The predictive validity, analyzed after the clinical application of Auto-DelRAS after one year, showed a sensitivity of 0.88, specificity of 0.72, positive predictive value of 0.53, negative predictive value of 0.94, and a Youden index of 0.59.

CONCLUSIONS

A relatively high level of predictive validity was maintained with the Auto-DelRAS system, even one year after it was applied to clinical practice.

Perceptions, attitudes, and current practices regards delirium in China: A survey of 917 critical care nurses and physicians in China

The purpose of this study is to assess the knowledge, attitudes, and managements regarding delirium of intensive care nurses and physicans, and to assess the perceived barriers related to intensive care unit (ICU) delirium monitoring in China. A descriptive survey was distributed to 1156 critical care nurses and physicians from 74 tertiary and secondary hospitals across Shandong province, China. The overall response rate was 86.18% (n = 917). The majority of respondents (88%) believed that deirium was associated with prolonged mechanical ventilation, and 79.72% thought delirium was associated with prolonged length of hospitalization. Only 14.17% of respondents believed that delirium was common in the ICU setting. Only 25.62% of the respondents reported routine screening of ICU delirium, and only 15.81% utilized Confusion Assessment Method for Intensive Care Unit screening tools. "Lack of appropriate screening tools" and "time restraints" were the most common perceived barriers. 45.4% of the participants had never received any education on ICU delirium. In conclusion, most nurses and physicians consider ICU delirium to be a serious problem, but lack knowledge on delirium and monitor this condition poorly. The survey infers a disconnection between the perceived significance and current monitoring of ICU delirium. There is a critical unmet need for in-service education on ICU delirium for physicians and nurses in China.

Development and validation of risk-stratification delirium prediction model for critically ill patients: A prospective, observational, single-center study

The objective is to develop a model based on risk stratification to predict delirium among adult critically ill patients and whether early intervention could be provided for high-risk patients, which could reduce the incidence of delirium.We designed a prospective, observational, single-center study. We examined 11 factors, including age, APACHE-II score, coma, emergency operation, mechanical ventilation (MV), multiple trauma, metabolic acidosis, history of hypertension, delirium and dementia, and application of Dexmedetomidine Hydrochloride. Confusion assessment method for the intensive care unit (CAM-ICU) was performed to screen patients during their ICU stay. Multivariate logistic regression analysis was used to develop the model, and we assessed the predictive ability of the model by using the area under the receiver operating characteristics curve (AUROC).From May 17, 2016 to September 25, 2016, 681 consecutive patients were screened, 61 of whom were excluded. The most frequent reason for exclusion was sustained coma 30 (4.4%), followed by a length of stay in the ICU < 24 hours 18 (2.6%) and delirium before ICU admission 13 (1.9%). Among the remaining 620 patients (including 162 nervous system disease patients), 160 patients (25.8%) developed delirium, and 64 (39.5%) had nervous system disease. The mean age was 55 ± 18 years old, the mean APACHE-II score was 16 ± 4, and 49.2% of them were male. Spearman analysis of nervous system disease and incidence of delirium showed that the correlation coefficient was 0.186 (P < .01). We constructed a prediction model that included 11 risk factors. The AUROC was 0.78 (95% CI 0.72-0.83).We developed the model using 11 related factors to predict delirium in critically ill patients and further determined that prophylaxis with Dexmedetomidine Hydrochloride in delirious ICU patients was beneficial. Patients who suffer from nervous system disease are at a higher incidence of delirium, and corresponding measures should be used for prevention.

Identifying Barriers to Delivering the Awakening and Breathing Coordination, Delirium, and Early Exercise/Mobility Bundle to Minimize Adverse Outcomes for Mechanically Ventilated Patients: A Systematic Review

BACKGROUND

Improved outcomes are associated with the Awakening and Breathing Coordination, Delirium, and Early exercise/mobility bundle (ABCDE); however, implementation issues are common. As yet, no study has integrated the barriers to ABCDE to provide an overview of reasons for less successful efforts. The purpose of this review was to identify and catalog the barriers to ABCDE delivery based on a widely used implementation framework, and to provide a resource to guide clinicians in overcoming barriers to implementation.

METHODS

We searched MEDLINE via PubMed, CINAHL, and Scopus for original research articles from January 1, 2007, to August 31, 2016, that identified barriers to ABCDE implementation for adult patients in the ICU. Two reviewers independently reviewed studies, extracted barriers, and conducted thematic content analysis of the barriers, guided by the Consolidated Framework for Implementation Research. Discrepancies were discussed, and consensus was achieved.

RESULTS

Our electronic search yielded 1,908 articles. After applying our inclusion/exclusion criteria, we included 49 studies. We conducted thematic content analysis of the 107 barriers and identified four classes of ABCDE barriers: (1) patient-related (ie, patient instability and safety concerns); (2) clinician-related (ie, lack of knowledge, staff safety concerns); (3) protocol-related (ie, unclear protocol criteria, cumbersome protocols to use); and, not previously identified in past reviews, (4) ICU contextual barriers (ie, interprofessional team care coordination).

CONCLUSIONS

We provide the first, to our knowledge, systematic differential diagnosis of barriers to ABCDE delivery, moving beyond the conventional focus on patient-level factors. Our analysis offers a differential diagnosis checklist for clinicians planning ABCDE implementation to improve patient care and outcomes.

Nurses' knowledge and perception of delirium screening and assessment in the intensive care unit: Long-term effectiveness of an education-based knowledge translation intervention

OBJECTIVES

To determine the impact of education on nurses' knowledge of delirium, knowledge and perception of a validated screening tool, and delirium screening in the ICU.

METHODS

A quasi-experimental single group pretest-post-test design.

SETTING

A 16 bed ICU in a Canadian urban tertiary care centre.

MAIN OUTCOME MEASURES

Nursing knowledge and perception were measured at baseline, 3-month and 18-month periods. Delirium screening was then assessed over 24-months.

RESULTS

During the study period, 197 surveys were returned; 84 at baseline, 53 at 3-months post education, and 60 at the final assessment period 18-months post intervention. The significant improvements in mean knowledge scores at 3-months post intervention (7.2, SD 1.3) were not maintained at 18-months (5.3, SD 1.1). Screening tool perception scores remained unchanged. Improvements in the perception of utility were significant at both time periods (p=0.03, 0.02 respectively). Physician value significantly improved at 18-months (p=0.01). Delirium screening frequency improved after education (p<0.001) demonstrating a positive correlation over time (p<0.01).

CONCLUSION

Multifaceted education is effective in improving delirium knowledge and screening; however, without sustained effort, progress is transient. Education improved perceived tool utility and over time utility perception and physician value improved.

Nurses' training in the use of a delirium screening tool

Objective

To narrate the nurses' training experience in the implementation of a systematic delirium screening tool using the Confusion Assessment Method for Intensive Care Unit.

Method

Experience report covering the steps of situation diagnosis, planning, staff training and evaluation of the tool's implementation between January and March 2013 with nurses in the ICU of a tertiary hospital in São Paulo.

Results

The implementation of the assessment, using the Confusion Assessment Method for Intensive Care Unit, obtained significant nurse adhesion and became a service indicator.

Final considerations

The experience has shown that this assessment allows the results of the work process to be analyzed and the consequent transformation of daily initiatives.

Intensive Care Unit Nurses' Beliefs About Delirium Assessment and Management

Delirium, the most frequent complication of hospitalized older adults, particularly in intensive care units (ICUs), can result in increased mortality rates and length of stay. Nurses are neither consistently identifying nor managing delirium in these patients. The purpose of this study was to explore ICU nurses' identification of delirium, actions they would take for patients with signs or symptoms of delirium, and beliefs about delirium assessment and management. In this cross-sectional study using qualitative descriptive methods guided by the theory of planned behavior, 30 ICU nurses' responses to patient vignettes depicting different delirium subtypes were explored. Descriptive and content analyses revealed that nurses did not consistently identify delirium; their actions varied in different vignettes. Nurses believed that they needed adequate staffing, balanced workload, interprofessional collaboration, and established policy and protocols to identify and manage delirium successfully. Research is needed to determine if implementing these changes increases recognition and decreases consequences of delirium.

Intensive care nurses' experiences and perceptions of delirium and delirium care

OBJECTIVE

To explore nurses' experiences and perceptions of delirium, managing delirious patients, and screening for delirium, five years after introduction of the Confusion Assessment Method for Intensive Care into standard practice.

RESEARCH DESIGN AND SETTING

Twelve nurses from a medical-surgical intensive care unit in a large teaching hospital attended two focus group sessions. The collected qualitative data was thematically analysed using Braun and Clarke's framework (2006).

FINDINGS

The analysis identified seven themes: (1) Delirium as a Secondary Matter (2) Unpleasant Nature of Delirium (3) Scepticism About Delirium Assessment (4) Distrust in Delirium Management (5) Value of Communication (6) Non-pharmacological Therapy (7) Need for Reviewed Delirium Policy.

CONCLUSION

Nurses described perceiving delirium as a low priority matter and linked it to work culture within the intensive care specialty. Simultaneously, they expressed their readiness to challenge this culture and to promote the notion of providing high-quality delirium care. Nurses discussed their frustrations related to lack of confidence in assessing delirium, as well as lack of effective therapies in managing this group of patients. They declared their appreciation for non-pharmacological interventions in treatment of delirium, suggested improvements to current delirium approach and proposed introducing psychological support for nurses dealing with delirious patients.

Implementing clinical practice guidelines for screening and detection of delirium in a 21-hospital system in northern California: real challenges in performance improvement

PURPOSE

The purpose of this article was to describe a quality improvement process on a diverse adult intensive care unit (ICU) population for a large healthcare organization for early detection of delirium.

BACKGROUND

Delirium is often considered a common unpreventable problem in the ICU. A process for early detection of delirium allows the critical care team to evaluate the patient and intervene to improve or reverse the delirium.

DESCRIPTION

A business case was first developed, and then using performance improvement methodology combined with quality improvement methods and oversight from a Delirium/Sedation Workgroup, an implementation plan was developed. Intensive care clinical nurse specialists were educated; patients in the ICU were screened for delirium twice daily by bedside nurses using the Confusion Assessment Method. The clinical nurse specialist in each ICU was instrumental for driving the process of change and supporting the bedside nurse and physicians to discuss preventing, screening, and treating delirium.

OUTCOME

System-wide process implementation was completed in 1 year, 2011. In 2012, all medical centers had a program in place to decrease the use of benzodiazepines and improve communication in the multidisciplinary teams during daily rounds about the treatment and prevention of delirium. The process of performance improvement is ongoing with continual reassessment and feedback required to ensure sustainability.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Performance improvement involving 21 medical centers is a large-scale undertaking by an organization. It requires a systematic approach with key stakeholders and advanced practice nurses as subject matter experts involved throughout all phases of the implementation. Bedside clinicians assessing the patient must feel supported and valued members of the process. Challenges of all care providers need to be acknowledged and addressed.

Nurses' and physicians' perceptions of Confusion Assessment Method for the intensive care unit for delirium detection: focus group study

BACKGROUND

Delirium in the intensive care unit (ICU) has received more attention in the past decade. Early detection, prevention and treatment of delirium are important, and the most commonly used tool for delirium assessment is the Confusion Assessment Method for the ICU (CAM-ICU).

AIM

The aim of this study was to identify nurses' and physicians' perceived professional barriers to using the CAM-ICU in Danish ICUs.

METHODS

This study uses a qualitative explorative multicentre design using focus groups and a semi-structured interview guide. Five focus groups with nurses (n = 20) and four with physicians (n = 14) were conducted. Strategic sampling was used to include participants with varying CAM-ICU experience at units, with variable implementation of the tool.

RESULTS

Using a hermeneutical approach, three main themes and nine sub-themes emerged. The main themes were (1) Professional role issues: CAM-ICU screening affected nursing care, clinical judgment and professional integrity; (2) Instrument reliability: nurses and physicians expressed concerns about CAM-ICU assessment in non-sedated patients, patients with multi-organ failure or patients influenced by residual sedatives/opioids; and (3) Clinical consequence: after CAM-ICU assessment, physicians lacked evidence-based treatment options, and nurses lacked physician acknowledgment and guidelines for disclosing CAM-ICU results to patients.

CONCLUSION

In this study, ICU nurses and physicians raised a number of concerns regarding the use of the CAM-ICU for delirium detection. It might be necessary to revalidate the instrument as ICU care has changed in recent years, with lighter sedation and early mobilization of patients. We recommend that nurses and physicians receive more training in the use of the CAM-ICU to address some of the issues identified in our study.

RELEVANCE TO CLINICAL PRACTICE

There is a need for ongoing training and clearer guidelines on how to proceed with the delirium screening of non-sedated patients.

Diagnosing delirium in very elderly intensive care patients

OBJECTIVE

To determine the incidence of delirium in elderly intensive care patients and to compare incidence using two retrospective chart-based diagnostic methods and a hospital reporting measure (ICD-10).

DESIGN

Retrospective study.

SETTING

An ICU in a large metropolitan private hospital in Melbourne, Australia.

PATIENTS

English-speaking participants (n=348) 80+ years, admitted to ICU for >24 hours.

MEASUREMENTS AND MAIN RESULTS

Medical files of ICU patients admitted October 2009-October 2012 were retrospectively assessed for delirium using the Inouye chart review method, DSM-IV diagnostic criteria and ICD-10 coding data. General patient characteristics, first onset of delirium symptoms, source of delirium information, administration of delirium medication, hospital and ICU length of stay, 90 day mortality were documented. Delirium was found in 11-29% of patients, the highest incidence identified by chart review. Patients diagnosed with delirium had higher 90 day mortality, and those meeting criteria for all three methods had longer hospital and ICU length of stay.

CONCLUSIONS

ICU delirium in the elderly is often under-reported and strategies are needed to improve staff education and diagnosis.

Validation of the delirium observation screening scale in a hospitalized older population

Delirium is challenging to diagnose in older populations. It is often reversible, and when detected, treatment can improve patient outcomes. Delirium detection currently relies on trained staff to conduct neurocognitive interviews. The Delirium Observation Screening Scale (DOS) is a screen designed to allow faster, easier identification of delirium. In this validation study, conducted at an academic tertiary care center, we attempted to determine the accuracy of the DOS as a delirium screening tool in hospitalized patients over 64 years old. We compared DOS results to a validated delirium diagnostic tool, the Delirium Rating Scale-Revised-98. We also assess the user-friendliness of the DOS by nurses via electronic survey. In 101 assessments of 54 patients, the DOS had sensitivity of 90% and specificity of 91% for delirium. The DOS is an accurate and easy way to screen for delirium in older inpatients.

Early recognition of delirium in trauma patients

OBJECTIVE

Evaluate change in practice and beliefs regarding delirium among nurses, pharmacists, respiratory therapists and physicians in a trauma intensive care unit.

METHODOLOGY/DESIGN/SETTING

Descriptive pre and post-design at a Level One Trauma Center. Education on causes of delirium, risk factors, strategies to prevent delirium and routine screening.

OUTCOME MEASURES

Change in practice and beliefs regarding delirium.

RESULTS

McNemars test measured the differences between pre- and post-questionnaires comparing the proportion of staff changed their responses in one direction to those who went in the opposite direction. Changes in "Delirium is largely preventable", were statistically significant (p=0.035). Haldol was the medication of choice for treating delirium, with an increase in use (p=0.062) post-intervention. The majority of participants believed a high percentage of patients experience delirium in a trauma intensive care. The two most frequent medical complications associated with delirium pre-questionnaire was over sedation 8 (22%) and falls 9 (24%) and in post-questionnaire, over sedation 12 (26%) and falls 13 (28%).

CONCLUSIONS

An educational intervention emphasising the importance of screening for delirium, risk factors for delirium and approaches to decrease the incidence of delirium can improve identifying and correctly treating delirium in a critical care setting. An educational program had concrete results in respondents' knowledge about delirium.

Attitudes, knowledge and practices concerning delirium: a survey among intensive care unit professionals

BACKGROUND

Delirium is a common form of vital organ dysfunction in intensive care unit (ICU) patients and is associated with poor outcomes. Adherence to guideline recommendations pertaining to delirium is still suboptimal.

AIMS

We performed a survey aimed at identifying barriers for implementation that should be addressed in a tailored implementation intervention targeted at improved ICU delirium guideline adherence.

DESIGN

The survey was conducted among ICU professionals.

METHODS

An online survey was conducted among 360 ICU health care professionals (nurses, physicians and delirium consultants) from six ICUs in the southwest of the Netherlands as part of a multicentre prospective implementation project [response rate: 64% of 565 invited; 283 (79%) were nurses].

RESULTS

Although the majority (83%) of respondents considered delirium a common and major problem in the ICU, we identified several barriers for implementation of a delirium guideline. The most important barriers were knowledge deficit, low delirium screening rate, lack of trust in the reliability of delirium screening tools, belief that delirium is not preventable, low familiarity with delirium guidelines, low satisfaction with physician-described delirium management, poor collaboration between nurses and physicians, reluctance to change delirium care practices, lack of time, disbelief that patients would receive optimal care when adhering to the guideline and the perception that the delirium guideline is cumbersome or inconvenient in daily practice.

CONCLUSION

Although ICU professionals consider delirium a serious problem, several important barriers to adhere to guidelines on delirium management are still present today.

RELEVANCE TO CLINICAL PRACTICE

Identification of implementation barriers for adherence to guidelines pertaining to delirium is feasible with a survey. Results of this study may help to design-targeted implementation strategies for ICU delirium management.

Clinical nurse specialist as change agent: delirium prevention and assessment project

PURPOSE/OBJECTIVES

The objective of this article is to address the role of the clinical nurse specialist (CNS) as a change agent in the implementation of a quality improvement program designed to prevent and assess delirium in ventilated patients at a community hospital.

BACKGROUND

Delirium is both a common condition that is not well recognized among patients in the intensive care unit (ICU) setting and a challenging problem to manage. Patients remain ventilated in ICU settings longer, and often, physical/occupational therapy is not started until after the patient is extubated; thus, the risk for delirium is high.

RATIONALE

The quality improvement program was implemented to recognize and decrease delirium in the critically ill patient. An understanding of the role of the CNS as the change agent provides a reference for other CNSs. The CNS's roles of communication, collaboration, and education in fulfilling the core competencies across the spheres of patient, nurse, and system are crucial when implementing lasting change.

DESCRIPTION

A review of the literature supports the use of the ABCDE Bundle to better manage pain, sedation, and delirium. The CNS uses Kurt Lewin's 3-step model of change to implement the quality improvement program.

OUTCOME

A CNS successfully implemented the ABCDE Bundle in a community hospital to improve the prevention and assessment of delirium in the ICU patient.

CONCLUSION

This project demonstrates the CNS's ability to implement a program to aid in the prevention and assessment of delirium in critically ill patients in the ICU.

IMPLICATIONS

The CNS's involvement as the change agent to implement the ABCDE Bundle is effective in the prevention and assessment of delirium in ventilated patients. The goal of the ABCDE Bundle is to extubate patients sooner and transfer them out of the ICU faster.

Intensive care nurses' opinions and current practice in relation to delirium in the intensive care setting

BACKGROUND

Delirium is a frequently encountered syndrome that negatively impacts on the well-being of the critically ill patient. Although international guidelines promote delirium monitoring, little is known regarding Irish intensive care (ICU) nurses' opinions and current practice in relation to delirium monitoring.

AIM

To ascertain ICU nurses' opinions on delirium among the critically ill and establish if delirium monitoring is part of current practice in the Republic of Ireland.

METHODS

A descriptive quantitative survey design was employed, utilising a self-report questionnaire. Participants were registered nurses selected using convenience sampling from two of the largest and leading teaching hospitals in the Republic of Ireland. The overall response rate was 70% (n=151/216).

FINDINGS

The majority of participants 143 (95%) recognised delirium as a serious problem and 93% considered delirium to be an under-diagnosed syndrome that requires active medical intervention. Only 17.9% reported screening for delirium and 4% ranked delirium important to monitor in the ICU setting. The majority of participants never attended a lecture (79%) or read an article (68%) pertaining to delirium.

CONCLUSION

The findings provide further evidence of the theory practice gap that is likely to exist internationally in settings where best practice guidelines on the management of delirium in the ICU setting are not implemented.

Knowledge of nurses about delirium in critical patients: collective subject discourse

This is an exploratory, descriptive and qualitative study with the aim of analyzing the knowledge of nurses in an intensive care unit about delirium in critically ill patients. Study participants were fourteen ICU nurses from a public hospital. Data were collected through semi-structured interviews and analyzed using the Collective Subject Discourse technique. Five features were identified after data analysis: signs and symptoms, use of sedatives, physical restraint, environment and lack of professional preparation. It was found that nurses have doubts concerning delirium, its management in intensive care, the use of scales and nursing interventions. This study points to the need for education on the subject and further research on the management of delirium in nursing.

A systematic review of implementation strategies for assessment, prevention, and management of ICU delirium and their effect on clinical outcomes

INTRODUCTION

Despite recommendations from professional societies and patient safety organizations, the majority of ICU patients worldwide are not routinely monitored for delirium, thus preventing timely prevention and management. The purpose of this systematic review is to summarize what types of implementation strategies have been tested to improve ICU clinicians' ability to effectively assess, prevent and treat delirium and to evaluate the effect of these strategies on clinical outcomes.

METHOD

We searched PubMed, Embase, PsychINFO, Cochrane and CINAHL (January 2000 and April 2014) for studies on implementation strategies that included delirium-oriented interventions in adult ICU patients. Studies were suitable for inclusion if implementation strategies' efficacy, in terms of a clinical outcome, or process outcome was described.

RESULTS

We included 21 studies, all including process measures, while 9 reported both process measures and clinical outcomes. Some individual strategies such as "audit and feedback" and "tailored interventions" may be important to establish clinical outcome improvements, but otherwise robust data on effectiveness of specific implementation strategies were scarce. Successful implementation interventions were frequently reported to change process measures, such as improvements in adherence to delirium screening with up to 92%, but relating process measures to outcome changes was generally not possible. In meta-analyses, reduced mortality and ICU length of stay reduction were statistically more likely with implementation programs that employed more (six or more) rather than less implementation strategies and when a framework was used that either integrated current evidence on pain, agitation and delirium management (PAD) or when a strategy of early awakening, breathing, delirium screening and early exercise (ABCDE bundle) was employed. Using implementation strategies aimed at organizational change, next to behavioral change, was also associated with reduced mortality.

CONCLUSION

Our findings may indicate that multi-component implementation programs with a higher number of strategies targeting ICU delirium assessment, prevention and treatment and integrated within PAD or ABCDE bundle have the potential to improve clinical outcomes. However, prospective confirmation of these findings is needed to inform the most effective implementation practice with regard to integrated delirium management and such research should clearly delineate effective practice change from improvements in clinical outcomes.

Nurses' knowledge and practices in cases of acute and chronic confusion: a questionnaire survey

PURPOSE

This study aimed to describe nurses' knowledge and practices toward patients with acute or chronic confusion.

DESIGN AND METHODS

A cross-sectional design was used, and 249 nurses engaged in clinical practice fulfilled an online self-report questionnaire.

FINDINGS

Tools for diagnosing acute confusion/delirium are never used by 57.80% of the nurses. Between 80% and 81% of nursing interventions involve managing patients' physical environment and between 62% and 71% deal with managing communication. Theoretical training in the use of tools for assessing and intervening in cases of confusion was significantly associated with nurses' knowledge and practices.

PRACTICE IMPLICATIONS

These results suggest the need for increased investment in nurses' training.

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

BACKGROUND

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.

AIM

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.

DESIGN

A descriptive, correlational study design was used.

METHODS

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.

RESULTS

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.

CONCLUSION

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.

RELEVANCE TO CLINICAL PRACTICE

It is essential to develop strategies to encourage ICU nurses to perform delirium assessments through the use of delirium assessment tools.

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

BACKGROUND

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.

AIMS AND OBJECTIVES

To evaluate the impact of an educational intervention on nurses' knowledge of sedation assessment and management.

DESIGNS AND METHODS

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.

RESULTS

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).

CONCLUSION

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.

RELEVANCE TO CLINICAL PRACTICE

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.

Managing hyperactive delirium and spinal immobilisation in the intensive care setting: a case study and reflective discussion of the literature

The management of ventilated patients on intensive care has, at its core, a care bundle; an evidence based group of actions designed to reduce the risk of ventilator-associated pneumonia. One of these is the daily cessation of sedation medication to expedite weaning from ventilatory support. A reflection-on-action exercise was carried out when a spinally injured patient became physically active during a sedation hold. This was attributed to hyperactive delirium. The concern was the conflict between providing evidence based Intensive Care Unit (ICU) therapy care and maintaining spinal immobility. Reflection on this incident led to a literature search for guidance on the likelihood of delirium causing secondary spinal injury in patients with unstable fractures. There was plentiful research on delirium and its consequences but very little examining the link between spinal injury and delirium. In order to be able to provide evidence-based care to future trauma patients the research supporting spinal immobilisation was also examined. The research showed that compliance with ventilator care bundles reduced the risks of acquiring ventilator-associated pneumonia. Research surrounding spinal immobilisation was conflicting and there were no studies linking the consequences of immobilised patients experiencing hyperactive delirium. Through a case study approach the research was reviewed in relation to a particular patient and although literature was lacking some implications for practice could be identified to promote the best possible outcomes. Sedation cessation episodes are an essential part of patient care on intensive care. For spinally injured patients' these may need to be modified to sedation reductions to prevent sudden wakening and uncontrolled movement should the patient be experiencing hyperactive delirium. This case study clearly highlights the need for further research in this area as the consequences of both ventilator associated pneumonia and extending spinal injuries is costly for both patients and hospitals.

Intensive care unit delirium: a review of the literature

PURPOSE

The recent literature regarding intensive care unit (ICU) delirium and updated clinical practice guidelines are reviewed.

SUMMARY

Recent studies show that ICU delirium in critically ill patients is an independent predictor of higher mortality, longer ICU and hospital stay, and is associated with multiple clinical complications. Delirium has been reported to occur in greater than 80% of hospitalized critically ill patients, yet it remains an underdiagnosed condition. Several subtypes of delirium have been identified including hypoactive, hyperactive, and mixed presentation. Although the exact mechanism is unknown, several factors are thought to interact to cause delirium. Multiple risk factors related to medications, acute illness, the environment, and patient characteristics may contribute to the development of delirium. Practical bedside screening tools have been validated and are recommended to identify ICU patients with delirium. Nonpharmacologic interventions such as early mobilization have resulted in better functional outcomes, decreased incidence and duration of delirium, and more ventilator-free days. Data supporting pharmacologic treatments are limited.

CONCLUSION

Clinicians should become familiar with tools to identify delirium in order to initiate treatment and remove mitigating factors early in hospitalization to prevent delirium. Pharmacists are in a unique position to reduce delirium through minimization of medication-related risk factors and development of protocols.

Delirium in the elderly adult in critical care

Several neurologic conditions are commonly seen with elderly adults in the critical care area. This article addresses a common neurologic condition commonly seen in elderly adults: delirium.

Top 10 myths regarding sedation and delirium in the ICU

The management of pain, agitation, and delirium in critically ill patients can be complicated by multiple factors. Decisions to administer opioids, sedatives, and antipsychotic medications are frequently driven by a desire to facilitate patients' comfort and their tolerance of invasive procedures or other interventions within the ICU. Despite accumulating evidence supporting new strategies to optimize pain, sedation, and delirium practices in the ICU, many critical care practitioners continue to embrace false perceptions regarding appropriate management in these critically ill patients. This article explores these perceptions in more detail and offers new evidence-based strategies to help critical care practitioners better manage sedation and delirium, particularly in ICU patients.

Automatic delirium prediction system in a Korean surgical intensive care unit

BACKGROUND

In Korea, regular screening for delirium is not considered essential. In addition, delirium is often associated with vague concepts, making it harder to identify high-risk patients and impeding decision-making.

AIMS

To assess the impact of the Automatic PREdiction of DELirium in Intensive Care Units (APREDEL-ICU) system on nursing-sensitive and patient outcomes for surgical ICU patients and to evaluate nurse satisfaction with the system and its usability.

METHODS

A pre-post research design was adopted. Our study included 724 patients admitted before the implementation of the APREDEL-ICU (January to December 2010) and 1111 patients admitted after the system was installed (May 2011 to April 2012). The APREDEL-ICU uses a pop-up window message to inform the nursing staff of patients at risk for delirium, allowing evidence-based nursing interventions to be applied to the identified patients. A total of 42 nurses were surveyed to determine the system's usability and their level of satisfaction with it.

RESULTS

After the implementation of APREDEL-ICU, high-risk patients, determined using a prediction algorithm, showed a slight decrease in the incidence of delirium, but the changes were not significant. However, significant decreases in the number and duration of analgesic/narcotic therapies were observed after the implementation of the system. Nurse self-evaluation results showed an improvement in all categories of knowledge regarding delirium care.

CONCLUSION

The use of a prediction and alerting system for ICU patients at high risk of delirium showed a potential increase in the quality of delirium care, including early detection and proper intervention.

An exploratory study of staff nurses' knowledge of delirium in the medical ICU: an Asian perspective

AIM

The aim of this study was to establish intensive care unit nurses' knowledge of delirium within an acute tertiary hospital within South East Asia.

BACKGROUND

Delirium is a common, life threatening and often preventable cause of morbidity and mortality among older patients. Undetected and untreated delirium is a catalyst to increased mortality, morbidity, functional decline and results in increased requirement for nursing care, healthcare expense and hospital length of stay. However, despite effective assessment tools to identify delirium in the acute setting, there still remains an inability of ICU nurses' to accurately identify delirium in the critically ill patient especially that of hypoactive delirium.

METHOD

A purposive sample of 53 staff nurses from a 13-bedded medical intensive care unit within an acute tertiary teaching hospital in South East Asia were asked to participate. A 40 item 5-point Likert scale questionnaire was employed to determine the participants' knowledge of the signs and symptoms; the risk factors and negative outcomes of delirium.

RESULTS

The overall positively answered mean score was 27 (67.3%) out of a possible 40 questions. Mean scores for knowledge of signs and symptoms, risk factors and negative outcomes were 9.52 (63.5%, n=15), 11.43 (63.5%, n=17) and 6.0 (75%, n=8), respectively.

CONCLUSION

Whilst the results of this study are similar to others taken from a western perspective, it appeared that the ICU nurses in this study demonstrated limited knowledge of the signs and symptoms, risk factors and negative outcomes of delirium in the critically patient. The implications for practice of this are important given the outcomes of untreated delirium.

Risk Factors for Acute Delirium in Critically Ill Adult Patients: A Systematic Review

Background. Delirium is characterized by disturbances of consciousness, attention, cognition, and perception. Delirium is a serious but reversible condition associated with poor clinical outcomes. This has implications for the critically ill patient; the effects of delirium cause long term sequelae, principally cognitive deficits, and functional decline. Objectives. The objective of the paper was to describe risk factors associated with delirium in critically ill adult patients. Methods. Published and unpublished literature from 1990 to 2012, limited to English, was searched using ten databases. Results. Twenty-two studies were included in this paper. A large number of risk factors were presented in the literature; some of these were common across all settings whilst others were exclusive to the type of setting. Benzodiazepines and opioids were shown to be risk factors for delirium independent of setting. Conclusion. With regard to patients admitted to medical and surgical intensive care units, risk factors of older age and comorbidity were common. In the cardiac ICU, older age and lower Mini-Mental Status Examination scores were cited most often as risk factors for delirium, but other risk factors exclusive to the setting were also significant. Benzodiazepines were identified as the most significant pharmacological risk factor for delirium.

Pharmacologic prevention and treatment of delirium in critically ill and non-critically ill hospitalised patients: a review of data from prospective, randomised studies

Delirium occurs commonly in acutely ill hospitalised patients, particularly in the elderly or in cardiac or orthopaedic surgery patients, or those in intensive care units (ICUs). Delirium worsens outcome. Pharmaceutical agents such as antipsychotics and, in the critically ill, dexmedetomidine, are considered therapeutic despite uncertainty regarding their efficacy and safety. Using MEDLINE, we reviewed randomised controlled trials (RCTs) published between 1977 and April 2012 evaluating a pharmacologic intervention to prevent or treat delirium in critically ill and non-critically ill hospitalised patients. The number of prospective RCTs remains limited. Any conclusions about pharmacologic efficacy are limited by the small size of many studies, the inconsistency by which non-pharmacologic delirium prevention strategies were incorporated, the lack of a true placebo arm and a failure to incorporate ICU and non-ICU clinical outcomes. A research framework for future evaluation of the use of medications in both ICU and non-ICU is proposed.

The incidence of delirium in Norwegian intensive care units; deep sedation makes assessment difficult

BACKGROUND

Delirium in critically ill patients is associated with increased length of hospital stay, mortality and costs, and may lead to long-term cognitive impairment. It is often overlooked by clinicians if structured observation is not performed routinely. A national Norwegian survey reported that systematic screening and assessment of delirium were never or seldom performed. The purpose of this study was to test the usefulness of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and to describe the incidence of delirium in critically ill patients at two Norwegian hospitals.

METHODS

We conducted a two-site, prospective, descriptive study including patients between 18 and 80 years, intubated or mask ventilated at admission, with an ICU stay > 48 h. The CAM-ICU was scored three times daily. In addition, illness severity, sedation level, pain assessment, drug use and other treatment factors were systematically assessed.

RESULTS

Total ICU stays of 139 patients were studied and covered 958 patient days. The incidence of delirium was 23%. Thirty per cent of the patients representing 407 patient days were unable to be assessed at any assessment, mainly due to deep sedation. The patients were delirium and coma free in 45.9% of total days.

CONCLUSION

Of the patients, 23% were classed as delirious (CAM-ICU positive) at least once during their stay. The CAM-ICU was difficult to use in patients with sedation so deep that they hardly gave eye contact and responded only weakly to verbal stimulation. Focusing on less sedation and further modifications to the CAM-ICU may benefit ICU patients in the future.

Optimising the recognition of delirium in the intensive care unit

Delirium affects up to 80% of critically ill patients and negatively influences patient outcome. Consensus guidelines advocate that a validated screening tool like the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) or the Intensive Care Delirium Screening Checklist (ICDSC) be used to identify delirium rather than a subjective approach. The CAM-ICU and ICDSC have the most rigorous psychometric data to support their use. The differences between these two instruments are far less important to the outcome of patients than the regular and reliable use of either in routine ICU care. Implementation of a large-scale delirium screening effort is both feasible and sustainable and should be accompanied by both didactic and bedside education. An ICU clinical road map should be used on a daily basis that promotes delirium assessment, establishes a targeted sedation goal and defines the analgesic/sedative regimen that is best suited to maintain patient comfort, prevent delirium and promote wakefulness.

Sedation practice in Nordic and non-Nordic ICUs: a European survey

BACKGROUND AND AIMS

A trend towards lighter sedation has been evident in many intensive care units (ICUs). The aims of the survey were to describe sedation practice in European ICUs and to compare sedation practice in Nordic and non-Nordic countries.

DESIGN AND METHODS

A cross-sectional survey of ICU nurses attending the fourth European federation of Critical Care Nursing associations (EfCCNa) in Denmark, 2011. Data included use of protocols; sedation, pain and delirium assessment tools; collaborative decision-making; sedation and analgesic medications; and educational preparation related to sedation.

RESULTS

Response rate was 42% (n = 291) from 22 countries where 53% (n = 148) used sedation protocols. Nordic nurses reported greater use of sedation (91% versus 67%, p < 0·01) and pain (91% versus 69%, p < 0·01) assessment tools than non-Nordic nurses. Decision-making on sedation was more inter-professionally collaborative in Nordic ICUs (83% versus 61%, p < 0·01), units were smaller (10 versus 15 beds, p < 0·01) and nurse-patient ratio was higher (1:1, 75% versus 26%, p < 0·01). Nordic nurses reported greater consistency in maintaining circadian rhythm (66% versus 49%, p < 0·01), less use of physical restraints (14% versus 36%, p < 0·01), less use of neuromuscular blocking agents (3% versus 16%, p < 0·01), and received more sedation education (92% versus 76%, p < 0·01). Delirium assessment was not performed systematically in most settings.

CONCLUSIONS

Organizational and contextual factors, such as ICU size, staffing ratio and inter-professional collaboration, are contributing factors to sedation management in European ICUs. The Nordic context might be more germane to the goal of lighter sedation and better pain management.

RELEVANCE TO CLINICAL PRACTICE

Our study raises awareness of current sedation practice, paving the way towards optimized ICU sedation management.

Implementation of a validated delirium assessment tool in critically ill adults

AIM

To evaluate the feasibility and effectiveness of the validated Confusion Assessment Method-ICU (CAM-ICU) delirium screening tool in a critical care unit.

DESIGN

A single centre service evaluation design was conducted in an 18 bed critical care unit comprising medical and surgical patients. Two self report questionnaires were administered to nursing staff (n=78) one immediately prior to and then three months following delirium education and CAM-ICU practical training.

RESULTS

The response rates of the questionnaires were 92% (72/78) and 60% (47/78) respectively, completed by predominantly females with a similar age range across the two groups. Prior to education and training 54% (39/72) of nurses agreed that delirium was a significantly underdiagnosed problem. Few nurses (6%, 4/72) considered evaluating their patients for it and 69% (50/72) did not feel the need to routinely monitor. Following a simple educational intervention 68% (32/47) believed delirium was a very serious problem, 74.5% (35/47) frequently evaluated their patients and only 31% (15/47) felt that CAM-ICU assessments should not be part of routine nursing care. The majority (85.1%, 40/47) of nurses found the CAM-ICU easy to administer, were confident in using the tool (74.4%, 35/47) and felt it led to a more comprehensive patient assessment (83%, 39/47). Despite this, barriers to undertaking delirium assessment identified at the start of the project remained and included patient intubation (42%, 20/47), sedation level (40%, 19/47) and medical staff inability to act on CAM-ICU assessment data (25%, 12/47).

CONCLUSION

This service evaluation has shown that implementation of a delirium screening tool into daily nursing practice is achievable within a relatively short time period. A simple, educational intervention incorporating written and video information improved the capacity of critical care nurses to perform delirium assessments in a standardised way and reduced the discordance between the perceived importance of delirium and the practice of its evaluation. Such data is especially important since delirium assessments had not traditionally been part of daily nursing care.

Critical care nurses' role in implementing the "ABCDE bundle" into practice

Imagine working in an environment where all patients undergoing mechanical ventilation are alert, calm, and delirium free. Envision practicing in an environment where nonvocal patients can effectively express their need for better pain control, repositioning, or emotional reassurance. Picture an intensive care unit where a nurse-led, interprofessional team practices evidence-based, patient-centered care focused on preserving and/or restoring their clients' physical, functional, and neurocognitive abilities. A recently proposed bundle of practices for the intensive care unit could advance the current practice environment toward this idealized environment. The Awakening and Breathing Coordination, Delirium Monitoring and Management, and Early Mobility (ABCDE) bundle incorporates the best available evidence related to delirium, immobility, sedation/analgesia, and ventilator management in the intensive care unit for adoption into everyday clinical practice.

Using Diffusion of Innovations Theory to implement the confusion assessment method for the intensive care unit

Routine screening of mechanically ventilated patients for delirium is essential for prompt recognition and management; however, this represents a change in practice. Rogers' Diffusion of Innovations Theory can be useful as a strategy to facilitate adoption of a practice change. This case study describes the effectiveness of identifying barriers to a change in practice and developing strategies, specific to Rogers' innovation decision process, for implementing the Confusion Assessment Method for the intensive care unit.

An electronic tool for visual feedback to monitor the adherence to quality indicators in intensive care medicine

Evidence-based medicine is often inadequately implemented in intensive care units (ICU); the aim of this study was to improve its implementation via a technical feedback system, using key performance indicators (KPI). The study evaluated 205 patients treated in a cardiac surgical ICU over a 6-month period (3 months before and 3 months after implementation of the feedback system). KPI adherence rates for sedation, delirium and pain monitoring, and completion of a weaning protocol before and after the implementation of the feedback system, were compared. Adherence rates for pain and delirium monitoring, and implementation of the weaning protocol, were significantly increased by the intervention. Adherence to KPIs for sedation, which were high at baseline, could not be further improved. Daily display of KPI implementation had a positive effect on adherence to standard operating procedures. Adherence to guidelines may be improved by using this feedback system as part of the clinical routine.
