Effectiveness of supporting intensive care units on implementing the guideline 'End-of-life care in the intensive care unit, nursing care': a cluster randomized controlled trial

The implementation of guidelines in palliative care - a scoping review

BACKGROUND

Guidelines are essential tools for ensuring high-quality healthcare. However, discrepancies exist between their availability and practical implementation. In the context of palliative care, the extent to which guidelines are implemented and the barriers and facilitators that influence this process remain unknown.

AIM

The present study aimed at systematically reviewing the international literature on the implementation of palliative care guidelines to evaluate factors that support or hinder implementation of palliative care guidelines globally.

METHOD

A scoping review was conducted following the methodological approach of Arksey and O'Malley (2005). After the formulation of research questions and development of a search string, relevant studies investigating the implementation of guidelines were identified and retrieved from the databases CINAHL, LIVIO, PubMed and Web of Science Core Collection on 4 January 2024. Two researchers independently selected articles for inclusion, employing a blinded process with predefined inclusion and exclusion criteria. The results were subsequently categorised deductively by the same researchers using Petermann's (2014) taxonomy of implementation outcomes. The results were summarised and presented in tabular form.

RESULTS

The search yielded 2,086 records, of which 1,252 were included in the title and abstract screening. Subsequently, 113 full-text articles were reviewed for eligibility, resulting in 29 articles deemed suitable for the final analysis. Six implementation outcomes were identified in the included literature: (1) acceptability (n = 15 articles), (2) adoption (n = 6 articles), (3) appropriateness (n = 9 articles), (4) feasibility (n = 9 articles), (5) fidelity/adherence (n = 14 articles) and (6) penetration (n = 14 articles). The majority of studies employed quantitative approaches (n = 22) and considered the perspective of healthcare professionals and their opinions regarding guideline implementation in palliative care. Only 4 articles considered patient related outcomes or the perspectives of the family caregivers. Ten articles reported on facilitators and barriers. Facilitators included healthcare professionals' motivation and managerial support, while barriers primarily referred to time constraints and limited knowledge.

CONCLUSIONS

Guideline implementation in palliative care is highly variable. Future research should aim at comprehensively analysing facilitators of and barriers to this process, considering diverse implementation outcomes. For these evaluations, mixed-method approaches are recommended.

The effect of end-of-life care awareness education on the knowledge, attitudes and behaviours of intensive care nurses: A randomized controlled trial

BACKGROUND

Education in end-of-life care (EoLC) is essential for improving the knowledge, attitudes and behaviours of intensive care nurses.

AIM

This study aimed to evaluate the effect of online awareness education, based on the End-of-Life Nursing Education Consortium, on the knowledge levels, attitudes and behaviours of intensive care nurses.

STUDY DESIGN

This single-centre randomized controlled study. This study was performed in a tertiary intensive care unit in a university-affiliated hospital. Seventy-six intensive care nurses were selected and equally randomized. In the education, the group was given an EoLC awareness education programme on an online platform as 40-60-min sessions once a week for 4 weeks. The descriptive Information Form, EoLC Knowledge Test and the Nurses' Attitudes and Behaviours towards the EoLC Scale were used. In the study, intensive care nurses' knowledge, attitude and behaviour levels towards EoLC were evaluated before and after 4 weeks (±3 days) following the education.

RESULTS

When the mean post-education scores of the nurses in the education group were compared with the control group, it was found that their mean scores on the EoLC Knowledge Test (p = .001, Cohen's d = 1.354, 95% CI = 3.240-6.549), the attitude sub-dimension (p = .001, Cohen's d = 1.520, 95% CI = 4.510-7.858), the behaviour sub-dimension (p = .001, Cohen's d = 1.425, 95% CI = 3.206-6.214) and the total attitude and behaviour (p = .001, Cohen's d = 1.927, 95% CI = 8.408-13.643) were statistically significantly higher than those of the control group.

CONCLUSION

This study showed that EoLC awareness education positively affected nurses' knowledge, attitudes and behaviours. Accordingly, planning EoLC awareness education online at regular intervals may be recommended for intensive care nurses.

RELEVANCE TO CLINICAL PRACTICE

Intensive care nurses may be given online EoLC awareness education to positively affect their knowledge, attitudes and behaviours about EoLC. Online EoLC education can be effective in terms of reaching a large number of nurses, time and cost.

Assessing palliative care practices in intensive care units and interpreting them using the lens of appropriate care concepts. An umbrella review

PURPOSE

Intensive care units (ICUs) have significant palliative care needs but lack a reliable care framework. This umbrella review addresses them by synthesising palliative care practices provided at end-of-life to critically ill patients and their families before, during, and after ICU admission.

METHODS

Seven databases were systematically searched for systematic reviews, and the umbrella review was conducted according to the guidelines laid out by the Joanna Briggs Institute (JBI).

RESULTS

Out of 3122 initial records identified, 40 systematic reviews were included in the synthesis. Six key themes were generated that reflect the palliative and end-of-life care practices in the ICUs and their outcomes. Effective communication and accurate prognostications enabled families to make informed decisions, cope with uncertainty, ease distress, and shorten ICU stays. Inter-team discussions and agreement on a plan are essential before discussing care goals. Recording care preferences prevents unnecessary end-of-life treatments. Exceptional end-of-life care should include symptom management, family support, hydration and nutrition optimisation, avoidance of unhelpful treatments, and bereavement support. Evaluating end-of-life care quality is critical and can be accomplished by seeking family feedback or conducting a survey.

CONCLUSION

This umbrella review encapsulates current palliative care practices in ICUs, influencing patient and family outcomes and providing insights into developing an appropriate care framework for critically ill patients needing end-of-life care and their families.

Intensive care unit interventions to improve quality of dying and death: scoping review

BACKGROUND

Intensive care units (ICUs) have mortality rates of 10%-29% owing to illness severity. Postintensive care syndrome-family affects bereaved relatives, with a prevalence of 26% at 3 months after bereavement, increasing the risk for anxiety and depression. Complicated grief highlights issues such as family presence at death, inadequate physician communication and urgent improvement needs in end-of-life care. However, no study has comprehensively reviewed strategies and components of interventions to improve end-of-life care in ICUs.

AIM

This scoping review aimed to analyse studies on improvement of the quality of dying and death in ICUs and identify interventions and their evaluation measures and effects on patients.

METHODS

MEDLINE, CINAHL, PsycINFO and Central Journal of Medicine databases were searched for relevant studies published until December 2023, and their characteristics and details were extracted and categorised based on the Joanna Briggs model.

RESULTS

A total of 24 articles were analysed and 10 intervention strategies were identified: communication skills, brochure/leaflet/pamphlet, symptom management, intervention by an expert team, surrogate decision-making, family meeting/conference, family participation in bedside rounds, psychosocial assessment and support for family members, bereavement care and feedback on end-on-life care for healthcare workers. Some studies included alternative assessment by family members and none used patient assessment of the intervention effects.

CONCLUSION

This review identified 10 intervention strategies to improve the quality of dying and death in ICUs. Many studies aimed to enhance the quality by evaluating the outcomes through proxy assessments. Future studies should directly assess the quality of dying process, including symptom evaluation of the patients.

Qualitative study on the perception of good death in patients with end-stage cancer in oncology nurses

OBJECTIVE

To explore the perception of good death of patients with end-stage cancer by nurses in the oncology department.

METHOD

In the study we used a phenomenological approach and semi-structured interviews. A total of 11 nurses from the oncology department of a Grade A hospital in Taizhou were interviewed on the cognition of good death from July 1 to September 30, 2022. Colaizzi's analysis method was used to analyse the interview data. This study followed the consolidated criteria for reporting qualitative research (COREQ).

RESULT

Four themes were identified: a strong sense of responsibility and mission; To sustain hope and faith; The important role of family members; Improve patients' quality of life.

CONCLUSION

The nurses in the department of oncology have a low level of knowledge about the "good death", and the correct understanding and view of the "good death" is the premise of the realization of " good death". The ability of nursing staff to improve the "good death", attention, and meet the needs and wishes of individuals and families, is the guarantee of the realization of "good death".

Implementation and efficacy of knowledge translation frameworks in family focused nursing care: A scoping review

AIM

To provide an overview of the characteristics, variety and outcomes of knowledge translation (KT) strategies used in nursing care involving adult patients and their family members.

BACKGROUND

The gap in providing family nursing practice could be due to a lack of explicit KT frameworks and understanding of ways to translate evidence-based knowledge into clinical practice.

DESIGN

A scoping review conducted according to the Joanna Briggs Institute.

METHODS

The review is reported according to PRISMA-ScR. Relevant studies were searched in MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CINAHL Complete, ProQuest Nursing & Allied Health Premium, PsycINFO, Social Work Abstracts, Social Services Abstracts and Scopus. Grey literature was searched in ProQuest Dissertations & Theses Global. Search results were imported into the web-based programme Covidence. Studies describing concepts of KT, strategies of implementation, involvement of families and nurses/family caregivers in adult health care and conducted within the last 15 years were included.

RESULTS

Eight studies met the inclusion criteria. Three studies used the KTA Framework to guide the implementation process. The remaining five studies used different frameworks/guidelines to translate a variety of family focused interventions into their clinical practice. Translation strategies were often targeted towards nurse education. Reported outcomes included nurses' attitudes towards and acceptance of involving families in health care. The outcomes were conceptualized and measured differently, showing inconclusive results on effectiveness on family focused care and family health.

CONCLUSION AND IMPLICATIONS FOR CLINICAL PRACTICE

The application of KT frameworks to implement evidence-based family nursing into clinical practice is limited. The process of KT mainly targets at nurses' adoption of family focused interventions with limited information about short-, intermediate- and long-term efficacy on family health. Clinical leaders should consider time and resources needed to implement family focused care KT strategies before putting it into practice.

Informing the standardising of care for prolonged stay patients in the intensive care unit: A scoping review of quality improvement tools

OBJECTIVES

To inform design of quality improvement tools specific to patients with prolonged intensive care unit stay, we determined characteristics (format/content), development, implementation and outcomes of published multi-component quality improvement tools used in the intenisve care unit irrespective of length of stay.

RESEARCH METHODOLOGY

Scoping review searching electronic databases, trial registries and grey literature (January 2000 to January 2022).

RESULTS

We screened 58,378 citations, identifying 96 studies. All tools were designed for use commencing at intensive care unit admission except three tools implemented at 3, 5 or 14 days. We identified 32 studies of locally developed checklists, 28 goal setting/structured communication templates, 23 care bundles and 9 studies of mixed format tools. Most (43 %) tools were designed for use during rounds, fewer tools were designed for use throughout the ICU day (27 %) or stay (9 %). Most studies (55 %) reported process objectives i.e., improving communication, care standardisation, or rounding efficiency. Most common clinical processes quality improvement tools were used to standardise were sedation (62, 65 %), ventilation and weaning (55, 57 %) and analgesia management (58, 60 %). 44 studies reported the effect of the tool on patient outcomes. Of these, only two identified a negative effect; increased length of stay and increased days with pain and delirium.

CONCLUSION

Although we identified numerous quality improvement tools for use in the intensive care unit, few were designed to specifically address actionable processes of care relevant to the unique needs of prolonged stay patients. Tools that address these needs are urgently required.

Perceptions on the current content and pedagogical approaches used in end-of-life care education among undergraduate nursing students: a qualitative, descriptive study

BACKGROUND

With the aging of the population, high rates of cancer and comorbidity complexity, the end-of-life care for patients will be ever more important. Nurses have always played an essential role in end-of-life care. Insufficient education and training in end-of-life care has been regarded as a major reason of inadequate symptom recognition, symptom management, and communication which results in mental trauma for both the patient's family and attending health care providers. Undergraduate nurses do end-of-life care as part of their clinical learning. However, undergraduate nurses' perceptions of the education they received about end-of-life care are not documented.

OBJECTIVE

This study aimed to critically explore the current state of education regarding end-of-life care from the perspectives of undergraduate nurses.

METHODS

We used a descriptive qualitative design. Face-to-face semi-structured interviews were conducted from May to August 2020, with a purposive sample of 15 fourth-year undergraduate nurses who finished the internship. Data were transcribed verbatim and analyzed using content analysis.

FINDINGS

Three main themes relating to undergraduate nurses' experiences of end-of-life care education emerged from the thematic analysis: 1) Universities provide foundational knowledge about end-of-life care, but it still needs improvement; 2) Clinical practice consolidates and drives undergraduate nurses' knowledge, skills and confidence about end-of-life care; and 3) cultural attitudes of patients' family toward disease and death sometimes impedes learning and knowledge translation about end-of-life care.

CONCLUSION

Undergraduate nursing students benefit from not only theoretical content delivered in the university setting but also practice happened on clinical placement. The current undergraduate curriculum, related to end-of-life care, is disjointed. Meanwhile, undergraduate nurses' learning and knowledge translation of end-of-life care are impeded by cultural attitudes toward disease and death.

Use and effects of implementation strategies for practice guidelines in nursing: a systematic review

BACKGROUND

Practice guidelines can reduce variations in nursing practice and improve patient care. However, implementation of guidelines is complex and inconsistent in practice. It is unclear which strategies are effective at implementing guidelines in nursing. This review aimed to describe the use and effects of implementation strategies to facilitate the uptake of guidelines focused on nursing care.

METHODS

We conducted a systematic review of five electronic databases in addition to the Cochrane Effective Practice and Organization of Care (EPOC) Group specialized registry. Studies were included if implementation of a practice guideline in nursing and process or outcome of care provided by nurses were reported. Two reviewers independently screened studies, assessed study quality, extracted data, and coded data using the EPOC taxonomy of implementation strategies. For those strategies not included in the EPOC taxonomy, we inductively categorized these strategies and generated additional categories. We conducted a narrative synthesis to analyze results.

RESULTS

The search identified 46 papers reporting on 41 studies. Thirty-six studies used a combination of educational materials and educational meetings. Review findings show that multicomponent implementation strategies that include educational meetings, in combination with other educational strategies, report positive effects on professional practice outcomes, professional knowledge outcomes, patient health status outcomes, and resource use/expenditures. Twenty-three of the 41 studies employed implementation strategies not listed within the EPOC taxonomy, including adaptation of practice guidelines to local context (n = 9), external facilitation (n = 14), and changes to organizational policy (n = 3). These implementation strategies also corresponded with positive trends in patient, provider, and health system outcomes.

CONCLUSIONS

Nursing guideline implementation may benefit from using the identified implementation strategies described in this review, including participatory approaches such as facilitation, adaptation of guidelines, and organizational policy changes. Further research is needed to understand how different implementation strategy components work in a nursing context and to what effect. As the field is still emerging, future reviews should also explore guideline implementation strategies in nursing in quasi or non-experimental research designs and qualitative research studies.

Rationale, Methodological Quality, and Reporting of Cluster-Randomized Controlled Trials in Critical Care Medicine: A Systematic Review

OBJECTIVE

Compared with individual-patient randomized controlled trials, cluster randomized controlled trials have unique methodological and ethical considerations. We evaluated the rationale, methodological quality, and reporting of cluster randomized controlled trials in critical care studies.

DATA SOURCES

Systematic searches of Medline, Embase, and Cochrane Central Register were performed.

STUDY SELECTION

We included all cluster randomized controlled trials conducted in adult, pediatric, or neonatal critical care units from January 2005 to September 2019.

DATA EXTRACTION

Two reviewers independently screened citations, reviewed full texts, protocols, and supplements of potentially eligible studies, abstracted data, and assessed methodology of included studies.

DATA SYNTHESIS

From 1,902 citations, 59 cluster randomized controlled trials met criteria. Most focused on quality improvement (24, 41%), antimicrobial therapy (9, 15%), or infection control (9, 15%) interventions. Designs included parallel-group (25, 42%), crossover (21, 36%), and stepped-wedge (13, 22%). Concealment of allocation was reported in 21 studies (36%). Thirteen studies (22%) reported at least one method of blinding. The median total sample size was 1,660 patients (interquartile range, 813-4,295); the median number of clusters was 12 (interquartile range, 5-24); and the median patients per cluster was 141 (interquartile range, 54-452). Sample size calculations were reported in 90% of trials, but only 54% met Consolidated Standards of Reporting Trials guidance for sample size reporting. Twenty-seven of the studies (46%) identified a fixed number of available clusters prior to trial commencement, and only nine (15%) prespecified both the number of clusters and patients required to detect the expected effect size. Overall, 36 trials (68%) achieved the total prespecified sample size. When analyzing data, 44 studies (75%) appropriately adjusted for clustering when analyzing the primary outcome. Only 12 (20%) reported an intracluster coefficient (median 0.047 [interquartile range, 0.01-0.13]).

CONCLUSIONS

Cluster randomized controlled trials in critical care typically involve a small and fixed number of relatively large clusters. The reporting of key methodological aspects of these trials is often inadequate.

A Scoping Review of Implementation Science in Adult Critical Care Settings

OBJECTIVES

The purpose of this scoping review is to provide a synthesis of the available literature on implementation science in critical care settings. Specifically, we aimed to identify the evidence-based practices selected for implementation, the frequency and type of implementation strategies used to foster change, and the process and clinical outcomes associated with implementation.

DATA SOURCES

A librarian-assisted search was performed using three electronic databases.

STUDY SELECTION

Articles that reported outcomes aimed at disseminating, implementing, or sustaining an evidence-based intervention or practice, used established implementation strategies, and were conducted in a critical care unit were included.

DATA EXTRACTION

Two reviewers independently screened titles, abstracts, and full text of articles to determine eligibility. Data extraction was performed using customized fields established a priori within a systematic review software system.

DATA SYNTHESIS

Of 1,707 citations, 82 met eligibility criteria. Studies included prospective research investigations, quality improvement projects, and implementation science trials. The most common practices investigated were use of a ventilator-associated pneumonia bundle, nutritional support protocols, and the Awakening and Breathing Coordination, Delirium Monitoring/Management, and Early Exercise/Mobility bundle. A variety of implementation strategies were used to facilitate evidence adoption, most commonly educational meetings, auditing and feedback, developing tools, and use of local opinion leaders. The majority of studies (76/82, 93%) reported using more than one implementation strategy. Few studies specifically used implementation science designs and frameworks to systematically evaluate both implementation and clinical outcomes.

CONCLUSIONS

The field of critical care has experienced slow but steady gains in the number of investigations specifically guided by implementation science. However, given the exponential growth of evidence-based practices and guidelines in this same period, much work remains to critically evaluate the most effective mechanisms to integrate and sustain these practices across diverse critical care settings and teams.

Developing and testing a nurse-led intervention to support bereavement in relatives in the intensive care (BRIC study): a protocol of a pre-post intervention study

BACKGROUND

When a patient is approaching death in the intensive care unit (ICU), patients' relatives must make a rapid transition from focusing on their beloved one's recovery to preparation for their unavoidable death. Bereaved relatives may develop complicated grief as a consequence of this burdensome situation; however, little is known about appropriate options in quality care supporting bereaved relatives and the prevalence and predictors of complicated grief in bereaved relatives of deceased ICU patients in the Netherlands. The aim of this study is to develop and implement a multicomponent bereavement support intervention for relatives of deceased ICU patients and to evaluate the effectiveness of this intervention on complicated grief, anxiety, depression and posttraumatic stress in bereaved relatives.

METHODS

The study will use a cross-sectional pre-post design in a 38-bed ICU in a university hospital in the Netherlands. Cohort 1 includes all reported first and second contact persons of patients who died in the ICU in 2018, which will serve as a pre-intervention baseline measurement. Based on existing policies, facilities and evidence-based practices, a nurse-led intervention will be developed and implemented during the study period. This intervention is expected to use 1) communication strategies, 2) materials to make a keepsake, and 3) a nurse-led follow-up service. Cohort 2, including all bereaved relatives in the ICU from October 2019 until March 2020, will serve as a post-intervention follow-up measurement. Both cohorts will be performed in study samples of 200 relatives per group, all participants will be invited to complete questionnaires measuring complicated grief, anxiety, depression and posttraumatic stress. Differences between the baseline and follow-up measurements will be calculated and adjusted using regression analyses. Exploratory subgroup analyses (e.g., gender, ethnicity, risk profiles, relationship with patient, length of stay) and exploratory dose response analyses will be conducted.

DISCUSSION

The newly developed intervention has the potential to improve the bereavement process of the relatives of deceased ICU patients. Therefore, symptoms of grief and mental health problems such as depression, anxiety and posttraumatic stress, might decrease.

Factors influencing the integration of a palliative approach in intensive care units: a systematic mixed-methods review

Background

While a palliative approach is generally perceived to be an integral part of the intensive care unit (ICU), the provision of palliative care in this setting is challenging. This review aims to identify factors (barriers and facilitators) influencing a palliative approach in intensive care settings, as perceived by health care professionals.

Method

A systematic mixed-methods review was conducted. Multiple electronic databases were used, and the following search terms were utilized: implementation, palliative care, and intensive care unit. In total, 1843 articles were screened, of which 24 met the research inclusion/exclusion criteria. A thematic synthesis method was used for both qualitative and quantitative studies.

Results

Four key prerequisite factors were identified: (a) organizational structure in facilitating policies, unappropriated resources, multi-disciplinary team involvement, and knowledge and skills; (b) work environment, including physical and psychosocial factors; (c) interpersonal factors/barriers, including family and patients’ involvement in communication and participation; and (d) decision-making, e.g., decision and transition, goal conflict, multidisciplinary team communication, and prognostication.

Conclusion

Factors hindering the integration of a palliative approach in an intensive care context constitute a complex interplay among organizational structure, the care environment and clinicians’ perceptions and attitudes. While patient and family involvement was identified as an important facilitator of palliative care, it was also recognized as a barrier for clinicians due to challenges in shared goal setting and communication.
