Does medicinal cannabis affect depression, anxiety, and stress in people with cancer? A systematic review and meta-analysis of intervention studies.

INTRODUCTION: Medicinal cannabis might have a role in supporting the mental health of people with cancer. This systematic review and meta-analysis examined the efficacy and safety of medicinal cannabis, compared with any control, as an intervention for depression, anxiety, and stress symptoms in people living with cancer. A secondary aim was to examine the effect of low versus high Δ9-tetrahydrocannabinol (THC) dose on these outcomes. METHODS: Five databases were systematically searched, and complemented with a snowball search from inception to May 2023, for any type of interventional study that included humans of any age with any cancer type. Primary outcomes were incidence and severity of depression, anxiety, and stress symptoms. Secondary outcomes were mood, cognition, quality of life, appetite, nutrition status, gastrointestinal symptoms, and adverse events. Data were pooled using Review Manager. Evidence was appraised using Cochrane risk of bias tools. Confidence in the estimated effect of pooled outcomes was assessed using Grading of Recommendations, Assessment, Development and Evaluation (GRADE). RESULTS: Fifteen studies (n = 11 randomized trials, n = 4 non-randomized trials) of 18 interventions (N = 1898 total participants; 100 % ≥18 years of age) were included. Ten studies examined THC (70 % synthetic), two synthetic cannabidiol with or without THC, and six whole-plant extracts. No clinically significant effects of medicinal cannabis were found on primary outcomes. The likelihood of anxiety events increased with higher-dose synthetic THC compared with a lower dose (OR: 2.0; 95 % CI: 1.4, 2.9; p < 0.001; Confidence: very low). Medicinal cannabis (THC, cannabidiol, and whole-plant extract) increased the likelihood of improved appetite (OR: 12.3; 95 % CI: 3.5, 45.5; p < 0.001; n = 3 interventions; Confidence: moderate) and reduced severity of appetite loss (SMD: -0.4; 95 % CI: -0.8, -0.1; p = 0.009; Confidence: very low). There was very low confidence that higher doses of synthetic THC increased the likelihood of any adverse event (OR: 0.5; 95 % CI: 0.3, 0.7; p < 0.001). Medicinal cannabis had no effect on emotional functioning, mood changes, confusion, disorientation, quality of life, and gastrointestinal symptoms. Confidence in findings was limited by some studies having high or unclear risk of bias and imprecise pooled estimates. CONCLUSIONS: There was insufficient evidence to determine the efficacy and safety of medicinal cannabis as a therapeutic intervention for depression, anxiety, or stress in people with active cancer. Further research should explore whether medicinal cannabis might improve and maintain appetite and if high-dose synthetic THC might increase the incidence of side-effects, including anxiety. To inform clinical practice, well-powered and rigorously designed trials are warranted that evaluate the effects of medicinal cannabis prescribed to target anxiety, depression, and stress.

Supportive Care in Pediatric Oncology: Opportunities and Future Directions.

The optimization of outcomes for pediatric cancer patients relies on the successful advancement of supportive care to ease the treatment burden and mitigate the long-term impacts of cancer therapy. Advancing pediatric supportive care requires research prioritization as well as the development and implementation of innovations. Like the prevailing theme throughout pediatric oncology, there is a clear need for personalized or precision approaches that are consistent, evidence-based, and guided by clinical practice guidelines. By incorporating technology and datasets, we can address questions which may not be feasible to explore in clinical trials. Now is the time to listen to patients' voices by using patient-reported outcomes (PROs) to ensure that their contributions and experiences inform clinical care plans. Furthermore, while the extrapolation of knowledge and approaches from adult populations may suffice in the absence of pediatric-specific evidence, there is a critical need to specifically understand and implement elements of general and developmental pediatrics like growth, nutrition, development, and physical activity into care. Increased research funding for pediatric supportive care is critical to address resource availability, equity, and disparities across the globe. Our patients deserve to enjoy healthy, productive lives with optimized and enriched supportive care that spans the spectrum from diagnosis to survivorship.

Cannabinoids for symptom management in children with cancer: A systematic review and meta-analysis.

BACKGROUND: Despite the widespread use of medical cannabis, little is known regarding the safety, efficacy, and dosing of cannabis products in children with cancer. The objective of this study was to systematically appraise the existing published literature for the use of cannabis products in children with cancer. METHODS: This systematic review, registered with the International Prospective Register of Systematic Reviews (CRD42020187433), searched four databases: MEDLINE, Embase, PsycINFO, and the Cochrane Library. Abstracts and full texts were screened in duplicate. Data on types of cannabis products, doses, formulations, frequencies, routes of administration, indications, and clinical and demographic details as well as reported efficacy outcomes were extracted. Data on cannabinoid-related adverse events were also summarized. RESULTS: Out of 34,611 identified citations, 19 unique studies with a total of 1927 participants with cancer were included: eight retrospective chart reviews, seven randomized controlled trials, two open-label studies, and two case reports. The included studies reported the use of various cannabis products for the management of symptoms. Cannabinoids were commonly used for the management of chemotherapy-induced nausea and vomiting (11 of 19 [58%]). In controlled studies, somnolence, dizziness, dry mouth, and withdrawal due to adverse events were more commonly associated with the use of cannabinoids. Across all included studies, no serious cannabis-related adverse events were reported. CONCLUSIONS: Although there is evidence to support the use of cannabis for symptom management, in children with cancer, there is a lack of rigorous evidence to inform the dosing, safety, and efficacy of cannabinoids. Because of the increasing interest in using cannabis, there is an urgent need for more research on medical cannabis in children with cancer.

A guide to navigating administrative data linkage for research.

Data linkage brings together information from various sources, including routinely collected administrative data or data from different research studies, to create a new, richer dataset. It provides insights into complex relationships between health and outcomes and evidence pathways to good health. However, when considering data linkage, there are several processes and practicality aspects that need to be explored. Some of these include understanding the costs, complexity of linkage, data storage requirements, required applications, and time lags. Taking these practicalities into consideration will lead to a more efficient process for data linkage.

Hospital-service use in the last year of life by patients aged ⩾60 years who died of heart failure or cardiomyopathy: A retrospective linked data study.

BACKGROUND: Understanding patterns of health care use in the last year of life is critical in health services planning. AIM: To describe hospital-based service and palliative care use in hospital in the year preceding death for patients who died of heart failure or cardiomyopathy in Queensland from 2008 to 2018 and had at least one hospitalisation in the year preceding death. DESIGN: A retrospective data linkage study was conducted using administrative health data relating to hospitalisations, emergency department visits and deaths. PARTICIPANTS AND SETTING: Participants included were those aged ⩾60 years, had a hospitalisation in their last year of life and died of heart failure or cardiomyopathy in Queensland, Australia. RESULTS: Of the 4697 participants, there were 25,583 hospital admissions. Three quarters (n = 3420, 73%) of participants were aged ⩾80 years and over half died in hospital (n = 2886, 61%). The median number of hospital admissions in the last year of life was 3 (interquartile range [IQR] 2-5). The care type was recorded as 'acute' for 89% (n = 22,729) of hospital admissions, and few (n = 853, 3%) hospital admissions had a care type recorded as 'palliative.' Of the 4697 participants, 3458 had emergency department visit(s), presenting 10,330 times collectively. CONCLUSION: In this study, patients who died of heart failure or cardiomyopathy were predominantly aged ⩾80 years and over half died in hospital. These patients experienced repeat acute hospitalisations in the year preceding death. Improving timely access to palliative care services in the outpatient or community setting is needed for patients with heart failure.

Assessment of Symptoms and Adverse Events Related to Immunotherapy in Patients With Cancer: An Integrative Review.

CONTEXT: Clinical practice guidelines advocate for routine assessment of symptoms and adverse events during immunotherapy treatment of cancer. Outside the clinical trial setting, there are few examples of such assessment in practice. OBJECTIVES: To identify, appraise, and synthesize the available literature regarding the assessment of immune-related symptoms and adverse events in patients with cancer beyond the clinical trial setting. Specifically, we aimed to identify the measurement instruments used, who completes these and when. METHODS: We completed an integrative review following established methods including a systematic literature search of electronic databases, a dual process for screening, quality appraisal, and data extraction. We included primary studies (retrospective or prospective) reporting the use of instruments or strategies to assess symptoms or adverse events in patients with cancer treated with immunotherapy. Outcomes of interest included: 1) how immune-related symptoms and adverse events were assessed; 2) types of assessment instruments; 3) frequency of instrument use and mode of administration; 4) the reported duration and intensity of symptoms and 5) adverse events and associated management strategies. Data were synthesized narratively. RESULTS: We screened 2138 articles and included 16 articles representing 2553 patients with cancer undergoing immunotherapy. All articles were published between 2018 and 2022 and were of sound methodological quality. Seven studies were retrospective chart reviews, and the remaining studies prospectively collected data, with seven collecting patient reported outcomes. In studies where data were collected at more than one time point (n = 6), weekly assessment during immunotherapy was the most common frequency. The potential for implementation of assessment into routine clinical practice was described in just four studies. CONCLUSION: Despite recommendations from clinical practice guidelines for routine assessment of symptoms and adverse events during immunotherapy treatment for cancer, there are few examples of how this is undertaken in clinical practice. The use of patient reported outcome measures to assess toxicity from immunotherapy is uncommon but offers the potential to identify symptoms early and facilitate timely intervention. Our review highlights the available instruments, how they have been used and the need for more applied research in this field to optimize patient outcomes.

Leveraging collective action and environmental literacy to address complex sustainability challenges.

Developing and enhancing societal capacity to understand, debate elements of, and take actionable steps toward a sustainable future at a scale beyond the individual are critical when addressing sustainability challenges such as climate change, resource scarcity, biodiversity loss, and zoonotic disease. Although mounting evidence exists for how to facilitate individual action to address sustainability challenges, there is less understanding of how to foster collective action in this realm. To support research and practice promoting collective action to address sustainability issues, we define the term "collective environmental literacy" by delineating four key potent aspects: scale, dynamic processes, shared resources, and synergy. Building on existing collective constructs and thought, we highlight areas where researchers, practitioners, and policymakers can support individuals and communities as they come together to identify, develop, and implement solutions to wicked problems. We close by discussing limitations of this work and future directions in studying collective environmental literacy.

Analysis of health administration data to inform health service planning for paediatric palliative care.

BACKGROUND: Health service planning in paediatric palliative care is complex, with the diverse geographical and demographic characteristics adding to the challenge of developing services across different nations. Accurate and reliable data are essential to inform effective, efficient and equitable health services. AIM: To quantify health service usage by children and young people aged 0-21 years with a life-limiting condition admitted to hospital and health service facilities in Queensland, Australia during the 2011 and 2016 calendar years, and describe the clinical and demographic characteristics associated with health services usage. DESIGN: Retrospective health administrative data linkage of clinical and demographic information with hospital admissions was extracted using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision Australian Modification (ICD-10-AM) diagnostic codes. Data were analysed using descriptive statistics. SETTING/PARTICIPANTS: Individuals aged 0-21 years with a life-limiting condition admitted to a Queensland Public Hospital and Health Service or private hospital. RESULTS: Hospital admissions increased from 17 955 in 2011 to 23 273 in 2016, an increase of 5318 (29.6%). The greatest percentage increase in admissions were for those aged 16-18 years (58.1%, n=1050), and those with non-oncological conditions (36.2%, n=4256). The greatest number of admissions by ICD-10-AM chapter for 2011 and 2016 were by individuals with neoplasms (6174, 34.4% and 7206, 31.0% respectively). Overall, the number of admissions by Indigenous children and young people increased by 70.2% (n=838). CONCLUSIONS: Administrative data are useful to describe clinical and demographic characteristics and quantify health service usage. Available data suggest a growing demand for health services by children eligible for palliative care that will require an appropriate response from health service planners.

I could have used a lot more help than I had: A qualitative systematic review and synthesis of families' experiences of paediatric brain tumour and schooling.

BACKGROUND: Brain tumours are the most common and fatal of all solid tumours for children and adolescents. The effects of the tumour and treatment (chemotherapy, radiation, and/or surgery) results in significant disruptions to childhood development and large amounts of missed schooling. Among other challenges for families, this produces obstacles for children and adolescents to achieve and maintain academic performance and experience positive schooling encounters. AIMS: We thus aimed to systematically identify and synthesize qualitative evidence on how families experience paediatric brain tumour from diagnosis and beyond with regards to their schooling and education to identify gaps in service delivery, research, and policy. METHODS: A protocol for this review was registered with PROSPERO (ID: CRD42020177165). Searches were conducted in Medline, CINAHL, PsycInfo, Embase, and Web of Science, and yielded 22 eligible papers (representing 17 studies). Data were extracted into NVivo12 and analysed by qualitative description. RESULTS: We formed the following domain summaries: academic (perceived failure to keep up with peers and finding success where one could, the importance of encouragement for diagnosed children), social (the importance of friendships and the harm of bullying), and support (the defining factor in overall return-to-school experience, often not enough received from educational professionals and clinicians). Our review highlights the need for more comprehensive, individualized, and integrated support for diagnosed children to return to educational institutions, and for the need to address their social experiences, particularly with regards to bullying, potentially through a school-wide social and emotional learning approach. CONCLUSION: Funding support, evidence-based guidelines, staff skill development, and clear communication structures across families, health care facilities, schools, and educational departments are essential to achieving this.

Enhancing paediatric palliative care: A rapid review to inform continued development of care for children with life-limiting conditions.

AIM: Following the establishment of paediatric palliative care services over recent decades, this study sought to identify information to inform future policy and practice. METHODS: A rapid review using thematic synthesis was conducted to synthesise existing information about improving paediatric palliative care. Information was extracted in relation to key areas for investment and change: quality, access, advance care planning, skills, research, collaboration and community awareness. RESULTS: A total of 2228 literature sources were screened, with 369 included. Synthesised information identified clear ways to improve quality of care, access to care, advance care planning, and research and data collection. The synthesis identified knowledge gaps in understanding how to improve skills in paediatric palliative care, collaboration across Australian jurisdictions and community awareness. CONCLUSIONS: The findings of this review bring together information from a vast range of sources to provide action-oriented information to target investment and change in paediatric palliative care over the coming decades.

Documentation of Symptoms in Children Newly Diagnosed With Cancer Highlights the Need for Routine Assessment Using Self-report.

BACKGROUND: Symptom management is a cornerstone of quality care and has the potential to vastly influence patient experiences. The supportive care needs of children, however, are not well described. OBJECTIVE: The aims of this study were to describe documentation about assessment and occurrence of symptoms in medical records of children with cancer and to compare the profile of documented symptoms with child self-report. METHODS: Twelve weeks of medical records of children (8-18 years) newly diagnosed with cancer were reviewed, and data were extracted regarding symptom assessment and occurrence. A second cohort of children attending oncology outpatients completed the electronic Symptom Screening in Pediatrics self-report of symptom bother. They also answered additional questions about other symptoms and the experience of self-report. We evaluated the profile of symptoms recorded as assessed by healthcare providers and self-reported by children. RESULTS: One thousand three hundred sixteen symptoms were identified in 3642 assessments. The symptoms most commonly documented by medical and nursing staff were nausea, pain, and appetite. Allied health staff most frequently documented fatigue, feeling scared, or sad. Forty-eight children completed self-report for the same symptoms and identified fatigue, appetite, and taste were the most bothersome. Children were positive about the experience of completing self-report. CONCLUSION: This study adds further to the evidence about the importance of obtaining information beyond routine clinical assessment from children themselves. IMPLICATIONS FOR PRACTICE: Healthcare providers do not routinely identify all distressing symptoms during clinical encounters. Use of patient-reported outcome measures in children is feasible and acceptable and empowers children to communicate about symptoms, which can facilitate prompt intervention.

Recruitment principles and strategies for supportive care research in pediatric oncology.

BACKGROUND: Variations in clinical practice contribute to negative outcomes for children with cancer. Research in this area is imperative to standardise practice, yet such research is challenging to undertake, and a significant proportion of studies fail. A common reason for failure is poor recruitment, yet little information is available to support researchers and clinicians planning such research. METHODS: Our primary aim was to describe the recruitment strategies and outcomes in a tertiary children's hospital across multiple observational supportive care studies. Secondary aims were to establish principles to improve both recruitment strategies and the reporting of recruitment. We undertook a retrospective descriptive analysis of the recruitment logs and data from three studies in pediatric oncology. The mean time to recruit one participant was calculated. Common reasons for not approaching eligible participants and reasons potential participants declined are described. RESULTS: Of the 235 potential candidates across all studies, 186 (79%) were approached and of these 125 (67%) provided consent, with 117 (63%) completing baseline measures. We estimated recruitment per participant required an average 98 min of experienced research nurse time. Four factors are described that influence recruitment and six principles are outlined to maximise recruitment and the generalisability of research findings. CONCLUSIONS: We highlight the recruitment experiences across three different projects in children's cancer supportive care research and provide a roadmap for other researchers planning to undertake clinical research in pediatrics.

Families' experiences of child and adolescent brain tumor: A systematic review and synthesis of qualitative research.

OBJECTIVES: Brain tumors are the most common and fatal of all solid tumors for children and adolescents; those who survive live with long-term physical and emotional consequences, as do their families. We aimed to synthesize relevant qualitative evidence on families' experiences and psychosocial service needs across the lifespan to identify gaps in care delivery and research. METHODS: Searches were conducted in Medline, CINAHL, PsycInfo, Embase, and Web of Science. Identified papers were assessed with the Joanna Briggs Institute Critical Appraisal Tool. Data were extracted into NVivo12 and analyzed by qualitative description and, where appropriate, thematic analysis. RESULTS: The search yielded 628 papers, of which 40 (33 studies) were eligible (6%). Although the methodological quality of the papers was low, we identified concerns that were consistently reported over time and from different perspectives. Individual family members had varying psychosocial needs to be addressed within healthcare, schooling, and public policy. These include for survivor's mental health (particularly for body image), and to the disproportionate biopsychosocial burden faced by mother-caregivers. CONCLUSIONS: Addressing the biological aspects of brain tumor cannot be our only focus. We have an obligation to provide services that meet the needs of families across diagnosis, treatment, survivorship, palliative care, and bereavement.

Estimating the prevalence of life-limiting conditions in Queensland for children and young people aged 0-21 years using health administration data.

Objective The prevalence of life-limiting conditions in children in Australia is unknown; such data are needed to inform health service planning for paediatric palliative care. The aim of this study was to estimate the prevalence of life-limiting conditions for children and young people aged 0-21 years living in Queensland, Australia. Methods An observational study using linked administrative health data from the 2011 and 2016 calendar years was performed for all individuals with an International Statistical Classification of Diseases and Related Health Problems 10th Revision Australian Modification code relating to a life-limiting condition eligible for palliative care recorded against an admission to a public or private hospital and health service provider in Queensland or against a cause or underlying cause of death in the Queensland Registrar General Deaths. Results The overall prevalence of life-limiting conditions per 10000 population increased from 35.2 (95% confidence interval (CI) 34.2-36.2) in 2011 to 43.2 (95% CI 42.1-44.4) in 2016. This increase in prevalence was greatest for children <1 year of age and for those who identified as Aboriginal and Torres Strait Islander. Conclusion This study has estimated the prevalence of life-limiting conditions for children and young people aged 0-21 years living in Queensland. Estimation of the number of children and young people with life-limiting conditions can inform health service planning for paediatric palliative care in Queensland. Future research is needed to identify the number of children and young people with life-limiting conditions who do not have an admitted episode. What is known about the topic? Data from the UK indicate that the prevalence of life-limiting conditions among children and young people is increasing. However, such data are not available for the Australian population. Because prevalence data can be affected by population characteristics, it is important to establish country-specific epidemiological data rather than extrapolating data from other countries. Country-specific data can inform health planners and policy makers of the scale of the problem within a geographical and demographic context. This is essential for Australia given the diverse geographical and demographic characteristics and specific needs of Aboriginal and Torres Strait Islander peoples. What does this paper add? This study is the first to provide an estimate of the prevalence of life-limiting conditions in children and young people aged 0-21 years in Queensland. Estimates include the prevalence of life-limiting conditions in children and young people who identify as being of Aboriginal and/or Torres Strait Islander descent. What are the implications for practitioners? The prevalence of life-limiting conditions in Queensland is greater than previously thought. There is a need to grow both a generalist and specialist paediatric palliative care workforce in response to this increasing prevalence. The estimates of prevalence proportions from this study provide the foundation on which future health service activities can be built because they provide country-specific clinical and demographic characteristics.

Early childhood environmental education: A systematic review of the research literature.

Environmental education focused on the early-childhood years is experiencing dynamic growth in research and practice due to persistent environmental challenges coupled with burgeoning interest in the documented benefits of nature-rich experiences for infants and children. To better understand the landscape of early childhood environmental education (ECEE) pedagogical practices and expected outcomes, we undertook a systematic review of empirical studies of ECEE programs. Focusing on a 25-year span, we surfaced 66 studies that met our inclusion criteria. We found that participants in such programs spanned the early-childhood age range (birth through age eight) with the majority involving three- to six-year-olds in teacher-led, formal (school-like) programs. The primary outcomes documented in our sample studies included environmental literacy development, cognitive development, and social and emotional development. To a lesser extent, the studies addressed physical development and language and literacy development. On balance, our sample of ECEE studies reported strongly positive findings associated with the aforementioned outcomes. The majority emphasized the effectiveness of play-based, nature-rich pedagogical approaches that incorporated movement and social interaction. We include a visualization that synthesizes cross-sample findings with the intention of assisting ECEE practitioners in developing, implementing, and evaluating programs as well as encouraging researchers to further study elements, processes, and theoretical assumptions inherent in them.

Organizational Strategies for Building Capacity in Evidence-Based Oncology Nursing Practice: A Case Report of an Australian Tertiary Cancer Center.

The ever-increasing cancer care demand has posed a challenge for oncology nurses to deliver evidence-based, innovative care. Despite efforts to promote evidence-based practice, barriers remain and executives find it difficult to implement evidence-based practice efficiently. Using the successful experience of an Australian tertiary cancer center, this paper depicts 4 effective strategies for facilitating evidence-based practice at the organizational level-the Embedded Scholar: Enabler, Enactor, and Engagement (4 Es) Model-includes a 12-week evidence-based practice program that prioritizes relevant research proposed by clinical staff and endorses high-quality, evidence-based point-of-care resources.

End-of-life care pathways for improving outcomes in caring for the dying.

BACKGROUND: This is an updated version of a Cochrane review published in Issue 11, 2013 in the Cochrane Library. In many clinical areas, integrated care pathways are utilised as structured multidisciplinary care plans that detail essential steps in caring for patients with specific clinical problems. In particular, care pathways for the dying have been developed as a model to improve care of patients who are in the last days of life. The care pathways were designed with an aim of ensuring that the most appropriate management occurs at the most appropriate time, and that it is provided by the most appropriate health professional. Since the last update, there have been sustained concerns about the safety of implementing end-of-life care pathways, particularly in the United Kingdom (UK). Therefore, there is a significant need for clinicians and policy makers to be informed about the effects of end-of-life care pathways via a systematic review. OBJECTIVES: To assess the effects of end-of-life care pathways, compared with usual care (no pathway) or with care guided by another end-of-life care pathway across all healthcare settings (e.g. hospitals, residential aged care facilities, community).In particular, we aimed to assess the effects on symptom severity and quality of life of people who are dying, or those related to the care, such as families, carers and health professionals, or a combination of these. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane Library; 2015, Issue 6), MEDLINE, EMBASE, PsycINFO, CINAHL, review articles, trial registries and reference lists of relevant articles. We conducted the original search in September 2009, and the second updated search in July 2015. SELECTION CRITERIA: All randomised controlled trials (RCTs), quasi-randomised trials or high quality controlled before-and-after studies comparing use versus non-use of an end-of-life care pathway in caring for the dying. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the results of the searches against the predetermined criteria for inclusion, assessed risk of bias, and extracted data. We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We screened 3028 titles, and included one Italian cluster RCT with 16 general medicine wards (inpatient units in hospitals) and 232 carers of cancer patients in this updated review. We judged the study to be at a high risk of bias overall, mainly due to a lack of blinding and rates of attrition. Only 34% of the participants (range 14% to 75% on individual wards) were cared for in accordance with the care pathway as planned. However, these issues were to be expected due to the nature of the intervention and condition. The study population was all cancer patients in their last days of life. Participants were allocated to care using the Liverpool Care Pathway (LCP-I, Italian version of a continuous quality improvement programme of end-of-life care) or to standard care. The primary outcomes of this review were physical symptom severity, psychological symptom severity, quality of life, and any adverse effects. Physical symptom severity was assessed as overall control of pain, breathlessness, and nausea and vomiting. There was very low quality evidence of a difference in overall control of breathlessness that favoured the Liverpool Care Pathway group compared to usual care: the study reported an odds ratio (OR) of 2.0 with 95% confidence intervals (CIs) 1.1 to 3.8. Very low quality evidence of no difference was found for pain (OR 1.3, 95% CI 0.7 to 2.6, P = 0.461) and nausea and vomiting (OR 1.5, 95% CI 0.7 to 3.2, P = 0.252). None of the other primary outcomes were assessed by the study. Limited data on advance care planning were collected by the study authors, making results for this secondary outcome unreliable. None of our other secondary outcomes were assessed by the study. AUTHORS' CONCLUSIONS: There is limited available evidence concerning the clinical, physical, psychological or emotional effectiveness of end-of-life care pathways.
