Music therapy for supporting informal carers of adults with life-threatening illness pre- and post-bereavement; a mixed-methods systematic review

BACKGROUND

Music therapy interventions with informal carers of individuals with life-threatening illness at pre- and post-bereavement is an increasingly important clinical area. This systematic review is the first to synthesise and critically evaluate the international evidence associated with music therapy with adult informal carers pre- and post-bereavement. Specifically, the objectives were: i) to describe the characteristics and effectiveness of music therapy interventions which aim to improve health-related outcomes for adult informal carers of adults with life-threatening illness (pre- and post-bereavement), and ii) to describe the experience of music therapy for adult informal carers of adults with life-threatening illness (pre- and post-bereavement).

METHODS

Eligibility: adult informal carers of adults at end of life or bereaved; music therapy interventions for improving health-related outcomes; qualitative; mixed-method; and quantitative studies including comparators of any other intervention; published in English from 1998 onwards. Six databases were searched up to July 2022. A JBI mixed-methods systematic review approach was followed throughout, including quality appraisal, data extraction and a convergent segregated approach to synthesis and integration.

RESULTS

A total of 34 studies were included, published between 2003 and 2022. Most were conducted in North America (n = 13), Australia (n = 10), or Europe (n = 8). No studies were conducted in low- and middle-income countries or in the UK. The majority were qualitative (n = 17), followed by quasi-experimental (n = 8), mixed-methods (n = 7) and two RCTs. The majority focused on carers of individuals with dementia (n = 21) or advanced cancer (n = 7). Seventeen studies were purely quantitative or included a quantitative component. During meta-synthesis, findings were aligned to core outcomes for evaluating bereavement interventions in palliative care and previously identified risk factors for complicated grief. Commonly targeted outcomes in quantitative studies included quality of life and mental wellbeing, showing equivocal effectiveness of music therapy with significant and non-significant results. Twenty-two studies either purely qualitative or with a qualitative component underwent meta synthesis and suggested a diverse range of improved pre- and post-bereavement outcomes for informal carers across all core outcomes, and across all risk and protective factors, including psychological, spiritual, emotional, and social outcomes.

CONCLUSIONS

Qualitative studies provide moderate to strong evidence for improved health-related outcomes for adult informal carers of adults with life-threatening illness pre-bereavement. Limited studies including those bereaved negates conclusions for the bereavement phase. Comparisons and explanations for effectiveness across quantitative and qualitative studies are equivocal, with a high risk of bias and small samples in the limited number of quantitative studies, demonstrating a need for high-quality RCTs.

Integrated palliative care in oncology: a protocol for a realist synthesis

INTRODUCTION

Emerging evidence suggests improved quality of life, reduced symptom burden and lower health services costs when integrated palliative care and cancer care are implemented. Integrated palliative care aims to achieve care continuity by integrating organisational, administrative and clinical services involved in patient care networks. However, integrated palliative care for cancer is not common practice. This project, therefore, aims to understand how integrated palliative care and cancer care works in different healthcare settings (inpatient/outpatient), and for which groups of people (at what stage of the cancer journey), so we can develop guidance for optimal delivery.

METHODS AND ANALYSIS

We will conduct a realist synthesis to develop a programme theory of how integrated palliative care in cancer works, for whom and in what contexts to achieve improved symptom management and quality of life for patients and their families.This realist synthesis will follow the five stages outlined by Pawson: (1) locating existing theories, (2) searching for evidence, (3) article selection, (4) extracting and organising data and (5) synthesising the evidence and drawing conclusions. We will work closely with our expert stakeholder group, which includes health and social care professionals providing palliative care and oncology; management and policy groups and members of the public and patients. We will adhere to RAMESES quality standards for undertaking a realist synthesis.

ETHICS AND DISSEMINATION

Ethics approval for this project is not required.The realist synthesis will develop a programme theory that provides clarity on the optimal delivery of palliative care for adults with cancer. We will use the programme theory to coproduce guidance and user-friendly outputs, working with stakeholders to inform delivery of best practice. Findings will inform further research in integrated palliative care and cancer. Stakeholder engagement will assist in the dissemination of our findings.

Developing a best-practice agenda for music therapy research to support informal carers of terminally ill patients pre- and post-death bereavement: a world café approach

BACKGROUND

Informal carers of terminally ill patients play a vital role in providing palliative care at home, which impacts on their pre- and post-death bereavement experience and presents an up to 50% greater risk for mental-health problems. However, developing and implementing effective bereavement support remains challenging. There is a need to build the evidence base for music therapy as a potentially promising bereavement support for this vulnerable population. This study aimed to co-design an international best practice agenda for research into music therapy for informal carers of patients pre- and post-death bereavement.

METHODS

Online half day workshop using a World Café approach; an innovative method for harnessing group intelligence within a group of international expert stakeholders (music therapy clinicians and academics with experience of music therapy with informal carers at end-of-life). Demographics, experience, key priorities and methodological challenges were gathered during a pre-workshop survey to inform workshop discussions. The online workshop involved four rounds of rotating, 25-minute, small group parallel discussions using Padlet. One final large group discussion involved a consensus building activity. All data were analysed thematically to identify patterns to inform priorities and recommendations.

RESULTS

Twenty-two consented and completed the pre-event survey (response rate 44%), from countries representing 10 different time zones. Sixteen participated in the workshop and developed the following best practice agenda. The effectiveness of music therapy in supporting informal carers across the bereavement continuum should be prioritised. This should be done using a mixed methods design to draw on the strengths of different methodological approaches to building the evidence base. It should involve service users throughout and should use a core outcome set to guide the choice of clinically important bereavement outcome measures in efficacy/effectiveness research.

CONCLUSIONS

Findings should inform future pre- and post-death bereavement support research for informal caregivers of terminally ill patients. This is an important step in building the evidence base for commissioners and service providers on how to incorporate more innovative approaches in palliative care bereavement services.

Integrating palliative care and heart failure: a systematic realist synthesis (PalliatHeartSynthesis)

OBJECTIVES

(1) Develop a programme theory of why, for whom and in what contexts integrated palliative care (PC) and heart failure (HF) services work/do not work; (2) use the programme theory to co-produce with stakeholders, intervention strategies to inform best practice and future research.

METHODS

A systematic review of all published articles and grey literature using a realist logic of analysis. The search strategy combined terms significant to the review questions: HF, PC and end of life. Documents were included if they were in English and provided data relevant to integration of PC and HF services. Searches were conducted in November 2021 in EMBASE, MEDLINE, PsycINFO, AMED, HMIC and CINAHL. Further relevant documents were identified via monthly alerts (up until April 2023) and the project stakeholder group (patient/carers, content experts and multidisciplinary practitioners).

RESULTS

130 documents were included (86 research, 22 literature reviews, 22 grey literature). The programme theory identified intervention strategies most likely to support integration of PC and HF services. These included protected time for evidence-based PC and HF education from undergraduate/postgraduate level and continuing professional practice; choice of educational setting (eg, online, face-to-face or hybrid); increased awareness and seeing benefits of PC for HF management; conveying the emotive and intellectual need for integrating PC and HF via credible champions; and prioritising PC and HF guidelines in practice.

CONCLUSIONS

The review findings outline the required steps to take to increase the likelihood that all key players have the capacity, opportunity and motivation to integrate PC into HF management.

Co-Designing a Strategy for Implementing the SPARC Holistic Needs Assessment Tool in the Colombian Clinical Context

In Colombia, timely access to palliative care (PC) is hampered by difficulties in identifying and referring to necessary services. The SPARC (Sheffield Profile for Assessment and Referral for Care) instrument provides a holistic needs assessment to improve referrals for different forms of care. SPARC was recently validated in Colombian Spanish (SPARC-Sp) but has not yet been implemented in clinical practice. We undertook workshops that aimed to co-design an implementation strategy to inform a future trial testing SPARC-Sp in the Colombian healthcare system. Workshop attendees included patients, informal caregivers, healthcare professionals, volunteers, administrative staff and decision makers. Discussions within the workshops refined implementation and dissemination strategies for SPARC-Sp in practical scenarios. Results include the need for education, clarification and demystification of PC and the lack of time and skills of professionals to identify patients' needs. Attendees recognized SPARC-Sp as a valuable tool for highlighting patients' concerns, whose adaptations are needed in Colombia to address the low literacy of the population and specificities of the healthcare system. We proposed local adaptations to SPARC-Sp and produced five educational videos aimed at health professionals, patients and caregivers to strengthen understanding of holistic needs in PC while building a strategy for SPARC-Sp implementation in the Colombian context.

Barriers and facilitators to palliative care for patients with non-curable cancer in Colombia: perspectives of allied health and social care professionals

BACKGROUND

Palliative care aims to improve the quality of life of people with life-limiting illness and their families by addressing physical, psychological, social and spiritual suffering. Allied Health and Social Care Professionals (AHSCP) are key to delivering comprehensive, high quality palliative care. In recent years, Colombia has developed changes in the legal, and regulatory framework for access to palliative care but barriers and facilitators to palliative care for patients with non-curable cancer have not been explored from the perspective of AHSCP.

METHOD

This study aims to address this knowledge gap in two cities in Colombia: one in a medium-sized city in a rural area (Popayan) and one in a highly urbanized area (Bogota). Two focus groups with AHSCP were conducted using the World Cafe method, and a subsequent thematic analysis was performed to establish the main barriers and facilitators.

RESULTS

A wide range of 18 AHSCPs attended the two World Cafe groups in Popayan and Bogota. As a result of this iterative process, we established five thematic areas: (i) Humanizing care, (ii) Normalizing palliative care: referral at the time of diagnosis, (iii) Misunderstandings related to palliative care, (iv) Barriers within the health system, and (v) Geographic barriers.

CONCLUSION

This study provided the perspectives of AHSCPs in Colombia in relation to barriers and facilitators in the framework of comprehensive palliative care attention. Participants identified misconceptions about palliative care, which are explained by the lack of inclusion of this area in the educational programs of health professionals and AHSCPs, along with the limited supply and access to palliative care, especially in rural areas.

'That just doesn't feel right at times' - lone working practices, support and educational needs of newly employed Healthcare Assistants providing 24/7 palliative care in the community: A qualitative interview study

BACKGROUND

Healthcare assistants working in hospice at home settings have a pivotal role in supporting people dying at home and their family caregivers. Some healthcare assistants are working alone in patients' homes, which magnifies some of the issues reported for those working closely with other team members. There is a dearth of evidence in terms of education, training and support needs for healthcare assistants when working alone.

AIM

To explore the role of newly employed lone working healthcare assistants delivering palliative care in the community, and their support and educational needs.

DESIGN

Qualitative exploratory study using semi-structured interviews.

SETTING/PARTICIPANTS

Healthcare assistants (n = 16) employed less than 12 months by a national non-profit hospice and palliative care provider located across the UK.

RESULTS

Analysis of interviews identified three main themes: (1) Healthcare assistants have a unique and complex role catering for holistic needs of patients and their family caregivers in the home environment; (2) preparation for the complex role requires focus on experiential learning and specific training to support holistic care provision; (3) lone workers experience loneliness and isolation and identify peer support as a key intervention to support their wellbeing.

CONCLUSIONS

Given the complexities of their role within community palliative care teams, there are key learning points in relation to healthcare assistant preparation. Education and support networks should be prioritised to reduce isolation and support ongoing learning and development of newly employed healthcare assistants; all of which is vital to ensure safety and quality of care for the growing number of people they support in the community.

Out-of-hours community palliative care: a national survey of hospice providers

BACKGROUND

Community-based palliative out-of-hours services operate outside normal working hours. However, little is known about the provision and delivery of such care.

AIM

The aim of this study was to describe types of provision and delivery of out-of-hours palliative care services provided by UK hospices.

METHODS

Survey questionnaires were emailed to 150 adult hospices in the UK. Quantitative data were analysed using SPSS and qualitative data subjected to thematic analysis.

FINDINGS

Responding hospices (n=57) provided the following types of support: telephone advice 72% (n=41); care at home 70% (n=40); and rapid response 35% (n=20). There were variations between services regarding referral mechanisms, availability and workforce, and integration with statutory services was limited.

CONCLUSION

Variation in the type of provision and delivery of out-of-hours palliative care services alongside limited integration with statutory care have contributed to inequity of access to community-based palliative care, and potentially suboptimal patient and informal caregiver outcomes.

'There's something about admitting that you are lonely' - prevalence, impact and solutions to loneliness in terminal illness: An explanatory sequential multi-methods study

BACKGROUND

Loneliness is a prevalent societal issue and can impact on a person's physical and mental health. It is unclear how loneliness impacts on end of life experiences or how such feelings can be alleviated.

AIM

To explore the perceived prevalence, impact and possible solutions to loneliness among people who are terminally ill and their carers in Northern Ireland through the lens of health and social care professionals.

DESIGN

An explanatory multi-method study.

SETTING/PARTICIPANTS

An online survey (n = 68, response rate 30%) followed by three online focus groups with palliative and end of life care health and social care professionals (n = 14). Data were analysed using descriptive statistics and thematic analysis.

RESULTS

Loneliness was perceived by professionals as highly prevalent for people with a terminal illness (92.6%) and their carers (86.8%). Loneliness was considered a taboo subject and impacts on symptoms including pain and breathlessness and overall wellbeing at end of life. Social support was viewed as central towards alleviating feelings of loneliness and promoting connectedness at end of life. Four themes were identified: (1) the stigma of loneliness, (2) COVID-19: The loneliness pandemic (3) impact of loneliness across physical and mental health domains and (4) the power of social networks.

CONCLUSION

There is a need for greater investment for social support initiatives to tackle experiences of loneliness at end of life. These services must be co-produced with people impacted by terminal illness to ensure they meet the needs of this population.

Communication of palliative care needs in discharge letters from hospice providers to primary care: a multisite sequential explanatory mixed methods study

Background

The provision of palliative care is increasing, with many people dying in community-based settings. It is essential that communication is effective if and when patients transition from hospice to community palliative care. Past research has indicated that communication issues are prevalent during hospital discharges, but little is known about hospice discharges.

Methods

An explanatory sequential mixed methods study consisting of a retrospective review of hospice discharge letters, followed by hospice focus groups, to explore patterns in communication of palliative care needs of discharged patients and describe why these patients were being discharged. Discharge letters were extracted for key content information using a standardised form. Letters were then examined for language patterns using a linguistic methodology termed corpus linguistics. Thematic analysis was used to analyse the focus group transcripts. Findings were triangulated to develop an explanatory understanding of discharge communication from hospice care.

Results

We sampled 250 discharge letters from five UK hospices whereby patients had been discharged to primary care. Twenty-five staff took part in focus groups. The main reasons for discharge extracted from the letters were symptoms “managed/resolved” (75.2%), and/or the “patient wishes to die/for care at home” (37.2%). Most patients had some form of physical needs documented on the letters (98.4%) but spiritual needs were rarely documented (2.4%). Psychological/emotional needs and social needs were documented in 46.4 and 35.6% of letters respectively. There was sometimes ambiguity in “who” will be following up “what” in the discharge letters, and whether described patients’ needs were resolved or ongoing for managing in the community setting. The extent to which patients received a copy of their discharge letter varied. Focus groups conveyed a lack of consensus on what constitutes “complexity” and “complex pain”.

Conclusions

The content and structure of discharge letters varied between hospices, although generally focused on physical needs. Our study provides insights into patterns associated with those discharged from hospice, and how policy and guidance in this area may be improved, such as greater consistency of sharing letters with patients. A patient-centred set of hospice-specific discharge letter principles could help improve future practice.

The impact of covid-19 on out-of-hours adult hospice care: an online survey

Background

Globally COVID-19 has had a profound impact on the provision of healthcare, including palliative care. However, there is little evidence about the impact of COVID-19 on delivery of out-of-hours specialist palliative care services in the United Kingdom. The aim of the study is to investigate the impact of the COVID-19 pandemic on the delivery of out-of-hours community-based palliative care services.

Methods

A national online census survey of managers of adult hospices in the United Kingdom was undertaken. Survey were emailed to managers of adult hospices (n = 150) who provided out-of-hours community palliative care services. Fifteen questions related specifically to the impact of COVID-19. Quantitative data were analysed using descriptive statistics and qualitative data were analysed using descriptive content analysis.

Results

Eighty-one responses to the survey were returned (54% response rate); 59 were complete of which 47 contained COVID-19 data. Findings indicated that COVID-19 impacted on out-of-hours community-based palliative care. To meet increased patient need, hospices reconfigured services; redeployed staff; and introduced new policies and procedures to minimize virus transmission. Lack of integration between charitably and state funded palliative care providers was reported. The interconnected issues of the use and availability of Personal Protective Equipment (n = 21) and infection control screening (n = 12) resulted in changes in nursing practices due to fear of contagion for patients, carers and staff.

Conclusions

Survey findings suggest that due to increased demand for community palliative care services, hospices had to rapidly adapt and reconfigure services. Even though this response to the pandemic led to some service improvements, in the main, out-of-hours service reconfiguration resulted in challenges for hospices, including workforce issues, and availability of resources such as Personal Protective Equipment. These challenges were exacerbated by lack of integration with wider healthcare services. More research is required to fully understand the implications of such changes on the quality of care provided.

Integrating palliative care and heart failure: a protocol for a realist synthesis (PalliatHeartSynthesis)

INTRODUCTION

Heart failure affects over 26 million people worldwide with prevalence expected to grow due to an ageing global population. Palliative care can address the holistic needs of patients with heart failure, and integrated palliative care in heart failure management has been indicated to improve outcomes for patients. Despite known benefits for integrated palliative care in heart failure management, implementation is poor across the majority of global health services. Recent systematic reviews have identified the benefits of integrating palliative care into heart failure management and highlighted barriers to implementation. However, there was heterogeneity in terms of countries, healthcare settings, delivery by differing staff across multidisciplinary teams, modes of delivery and different intervention components.

METHODS AND ANALYSIS

The aim of this study is to identify how integrated palliative care and heart failure interventions produce desired outcomes, in which contexts, and for which patients. We will undertake a realist synthesis to identify this, using Pawson's five iterative steps. We will recruit an international stakeholder group comprised of healthcare providers and patients with heart failure to advise and provide feedback throughout the review. Our initial realist programme theory sets out the necessary steps needed to accomplish the final intended outcome(s) from the implementation of integrated palliative care and heart failure. This initial programme theory will be shaped through an iterative process of testing and refinement.

ETHICS AND DISSEMINATION

Ethical approval is not required for this study. With our stakeholder group, we will coproduce a user guide that outlines practical advice to optimise, tailor and implement interventions designed to integrate palliative care and heart failure, taking into consideration local context, alongside user-friendly summaries of the synthesis findings using short animations to convey complex findings. We will draw on the expertise within the stakeholder group to identify key stakeholders for disseminating to relevant audiences, ensuring outputs are tailored for their respective needs.

Protocol for a mixed methods exploratory investigation into the role and contribution of the healthcare assistant in out-of-hours palliative care

BACKGROUND

Most people spend their last year of life at home, with many wishing to die there, but patients may need access to care after hours. Out-of-hours palliative care is delivered by multi-disciplinary teams including Health Care Assistants (HCA). However, little is known about the role, contribution and impact Health Care Assistants have on out-of-hours palliative care services. The aim of this study is to examine the Health Care Assistant role, contribution and impact on service delivery and patient care in out-of-hours community palliative care provided by hospice organisations.

METHODS AND ANALYSIS

A mixed methods exploratory study consisting of four phases. Phase one involves a scoping review to systematically map and identify gaps in policy and literature on the HCA role in out-of-hours palliative care. In phase two, all United Kingdom hospices will be invited to participate in an online census to enable the development of a typology of out-of-hours services and the contribution of the Health Care Assistant. During phase three organisational case studies representing different service types will collect information from Health Care Assistants, patients, caregivers and service managers to gather qualitative and quantitative data about out-of-hours service provision and the Health Care Assistant role. Finally, phase four will synthesize and refine results through online focus groups.

ETHICS AND DISSEMINATION

Ethical approval has been obtained for phase two through Ulster University Research Governance Filter Committee, Nursing and Health Research. Findings will be disseminated through practitioner and/or research journals, conferences, and social media.

Medication use and deprescribing in older patients in the last 14 days of life

Introduction

Older patients may continue to receive potential inappropriate medications (PIMs) at the end of life. Application of consensus-based tools to identify PIMs may result in the identification of candidate medications for deprescribing, with the aim of overcoming the harm of inappropriate medication and improving clinical outcomes. This study aims to describe medication use and deprescribing patterns, and to assess prescribing appropriateness for older people in the last 14 days of life in the hospice setting.

Methods

Longitudinal, retrospective cohort study of deceased patients (≥65 years) who died between 1 January 2018 and 31 December 2018 in three hospices in a region of the United Kingdom. We identified prescribed and deprescribed medications and assessed medication appropriateness using consensus-based criteria, namely STOPPFrail[1] and criteria developed by Morin et al.[2] Unexpected/sudden deaths were excluded. Statistical analysis was conducted using SPSS statistics 26.0.

Preliminary results

Data collection is currently ongoing. To date, data from 69 deceased patients have been collected (mean age 76.1 years). Of these decedents, 62.3% were female and the majority (just under 90%) had cancer reported as the cause of death. During the last 14 days of life, each patient was prescribed a mean of 17 ± 5 different medications. The mean number of medications decreased significantly between day 14 and the day of death from 13.2 ± 4.4 to 9.4 ± 3.7 (P < 0.01). Six hundred and thirty-nine medications were discontinued, with just under 70% stopped in the last seven days before death. 34.9% of those discontinued were prescribed for chronic conditions and 22% were proton pump inhibitors. In most decedents, swallowing difficulty was the reason for medication discontinuation. According to the STOPPFrail criteria [1], 42 (60.1%) of decedents received at least one PIM between day 14 and the day of death. There were 59 PIMs in total for these patients; of these 20.3% were hyoscine butyl-bromide and 16.9% were gliclazide. Using the criteria developed by Morin et al [2], 103 medications were assessed as being of questionable (81.6%) or inadequate (18.4%) clinical benefit. Of these, 64.1% were initiated during hospice admission. There was a statistically significant association between medications of questionable clinical benefit and medication number during the last 14 days of life (P < 0.01). Three of the PIMs were vitamins, considered inappropriate by both sets of criteria. Prescribing of PIMs reduced as patients neared death.

Conclusion

A substantial proportion of older patients with life-limiting diseases receive PIMs during their last days of life. No systematic discontinuation of inappropriate medications was observed thus guidelines and resources are needed to facilitate rationalisation and deprescribing of drug treatments for older patients in the last days of life. The small sample size makes the relationship between most variables insignificant; however, data extraction is still ongoing in hospices.

The roles, responsibilities and practices of healthcare assistants in out-of-hours community palliative care: A systematic scoping review

BACKGROUND

Access to community palliative care 'out-of-hours' - defined as care provided after the normal hours of work - is advocated globally. Healthcare assistants, who provide care under the direction of a qualified professional, are increasingly employed to help deliver such care, yet there is a little understanding regarding their role, responsibilities or contribution.

AIM

The aim of this study was to identify the roles, responsibilities and contributions of healthcare assistants in out-of-hours community palliative care.

DESIGN

Scoping review.

DATA SOURCES

Five bibliographic databases (CINAHL, MEDLINE, EMBASE, PsycINFO and Scopus) and grey literature were searched using a predefined search strategy. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews statement.

RESULTS

The search yielded six papers using quantitative, qualitative and mixed methods. Results highlighted a lack of recognition of the role and contribution of healthcare assistants. A concurrent theme was that healthcare assistants continually monitored and responded to patient's and family's physical and emotional needs; there was also self-reported evidence indicating patient and family benefit, such as maintaining a sense of normality and support to remain at home.

DISCUSSION

This review highlighted a dearth of evidence relating to the healthcare assistant role in out-of-hours palliative care. Limited evidence suggests they play a role, but that it is hidden and undervalued. Such invisibility will have a significant impact on the planning and delivery of out-of-hours palliative care. Future research is needed on role development for the benefit of patients and caregivers.

Group based video-conferencing for adults with depression: findings from a user-led qualitative data analysis using participatory theme elicitation

BACKGROUND

Accessing support services for depression has been historically difficult given the societal stigma that exists regarding the condition. Recent advances in digital technologies continue to be postulated as a potential panacea yet the results from research trials have been mixed with a range of effect sizes.

METHODS

This article offers a different perspective by presenting a panel of end users (co-researchers) with qualitative interview data (n = 8) taken from a feasibility RCT of a group based video-conferencing service for depressed adults. The co-researcher panel were introduced to a new method of participatory data analysis known as Participatory Theme Elicitation (PTE). This method involves using network analysis techniques to create groupings and visual diagrams in order to support the generation of themes and minimise scientific researcher input/influence.

RESULTS

Co-researchers reported that while VC based interventions appeared convenient, accessible and relatively low cost - additional training and support should be offered to improve uptake and retention. In addition, co-researchers suggested that further exploration is needed regarding the level of self-awareness one feels in a group based VC environment and whether this facilitates disclosure (through disinhibition) or increases anxiety.

CONCLUSION

The findings presented here appear to support existing (researcher and academic-led) literature in the field as well as suggest new areas for investigation. By presenting data generated solely by co-researchers, this article also adds to the evidence surrounding participatory analysis methods - particularly the growing need for robust approaches that are accessible and less time-consuming than those currently available.

Co-producing a shared understanding and definition of empowerment with people with dementia

BACKGROUND

Empowerment for people with dementia (PWD) is not well defined within the research literature and we feel that this is an important area for development. It is important to seek, consult, and co-produce such a definition with PWD who are more actively involved in their communities post diagnosis (e.g. no longer the 'long goodbye'). This study seeks to combine academic literature review methods with participatory/co-production methods in order to address this gap. We feel this approach also adds to developing methodologies in the field of co-production and user involvement.

METHODS

We use a unique approach toward a definition of empowerment for PWD. Phase 1 - A scoping review of medical/health, social care and social policy-based databases to identify any previous literature that may have defined empowerment exclusively for PWD. Based on this literature, we collected a list of terms relating to empowerment for PWD. Phase 2 - Using empowerment key terms set on cards formulated from Phase 1 across three co-production workshops, academic team members, and nine members of Dementia NI (an organisation founded and led by people with dementia) we reviewed the findings of this search and co-produced an agreed definition they felt best described empowerment for them.

RESULTS

Phase 1 and 2 led to a definition of empowerment relevant to PWD. This shared understanding of empowerment was defined by PWD as 'A confidence building process whereby PWD are respected, have a voice and are heard, are involved in making decisions about their lives and have the opportunity to create change through access to appropriate resources'.

CONCLUSIONS

The strength of this research lies in addressing the current confusion and arbitrariness of empowerment within the context of dementia. This coproduced work also provides evidence for not only the possibility, but also the added value of involving PWD in research in terms of unique insights afforded by their lived experiences.

The MusiQual treatment manual for music therapy in a palliative care inpatient setting

This article presents the treatment manual developed during the MusiQual feasibility study carried out in Belfast by Queen’s University Belfast, Every Day Harmony Music Therapy, and Marie Curie Northern Ireland. The MusiQual study considered the feasibility of a multicentre randomised trial to evaluate the effectiveness of music therapy in improving the quality of life of hospice inpatients (protocol: McConnell et al. results: Porter et al.). The procedures in the manual are based fully on those implemented by the Music Therapists during the feasibility study, and it also incorporates the theoretical model defined and published following the realist review of the literature (McConnell and Porter). The manual is presented in the format in which it would be used in the potential future phase III multicentre randomised control trial. It represents a flexible approach to provide enough scope for practicing therapists to adapt their interventions to individual clients as is best practice in music therapy. It aims to provide stable guidelines both to ensure treatment fidelity in a future trial of music therapy for palliative care inpatients and to act as a relevant guide for Music Therapists practicing in this field.

A randomised controlled pilot and feasibility study of music therapy for improving the quality of life of hospice inpatients

BACKGROUND

Evidence about the effectiveness of music therapy for improving the quality of life of palliative care patients is positive but weak in terms of risk of bias.

METHODS

This study aimed to determine the feasibility of a randomised controlled trial to evaluate the effectiveness of music therapy for improving the quality of life of hospice inpatients, as measured by the McGill Quality of Life questionnaire. Objectives included recruitment of 52 participants over 12 months and provision of data to support the calculation of the required sample size for a definitive randomised trial, taking into account the retention rates of recruited participants; and evaluation of the viability of the intervention and the acceptability of the assessment tool. The design was a single-centre, researcher-blinded randomised pilot and feasibility study involving two parallel groups. Participants were recruited from one inpatient hospice unit in Northern Ireland. Eligibility criteria were an Eastern Cooperative Oncology Group performance status of two or lower and an Abbreviated Mental Test score of seven or more. Consenting patients were randomly allocated to the intervention or control group using a 1:1 allocation ratio. The intervention group received up to six individual music therapy sessions over 3 weeks in addition to usual care. The control group received usual care only.

RESULTS

Fifty one participants were recruited over 12 months. Twenty five were allocated to the intervention group and 26 to the control group. Seventy one percent of participants were lost to follow up by week 3, the proposed primary endpoint. The primary endpoint was moved from week 3, when 71% were lost to follow up to week 1, when 33% were lost. The McGill Quality of Life questionnaire was generally acceptable to participants. In order to detect a small to moderate effect size of 0.3, a fully powered study would require the recruitment of 698 participants.

CONCLUSIONS

A Phase III randomised controlled trial to evaluate the effectiveness of music therapy in improving the quality of life of hospice inpatients is feasible.

A translational case study of empowerment into practice: A realist evaluation of a member-led dementia empowerment service

Involving people with dementia in decision-making is widely accepted as a means of empowering them to lead more independent lives and have more meaningful roles in shaping their care. However, there is a need to conduct rigorous evaluations of empowerment-driven services and policies in order to develop a deeper understanding about how to optimise successful implementation. This paper presents the results of an evaluation of Dementia Northern Ireland, an organisation initiated and led by people with dementia. We used a realist evaluation approach that comprised interviews with 15 people with dementia, three staff and two board members, ethnographic observations, along with documentary analysis to identify ‘what works, for whom, under what circumstances’. The analysis used realist logic to build up context-mechanism-outcome configurations. The Dementia Northern Ireland service model of empowerment revolved around the formation and maintenance of social groups of people with dementia. Facilitators, recruited and selected by people with dementia, supported six groups, consisting of one to four members with mild to moderate cognitive impairment. Facilitators helped expand empowerment groups, facilitate decision-making, awareness raising and consultation opportunities with group members. The ‘Empowerment Groups’ appeared to lead to the development of a shared social identity and a sense of collective strength as indicated by interview and observational data demonstrating an activist mentality among group members to challenge the stigma surrounding dementia. Group members also reported improved quality of life. Widespread implementation of the empowerment model has the potential to lead to reduced stigma and greater social inclusion, increased involvement of people with dementia as active co-producers of policy and service development, better services and support. This case study of Dementia Northern Ireland illustrates that there are boundaries and challenges to empowerment in terms of requiring additional support from staff without dementia. However, despite these challenges, empowerment-driven organisations can and should be committed to involving members in lead roles and key decision-making.

Coproduction for feasibility and pilot randomised controlled trials: learning outcomes for community partners, service users and the research team

PLAIN ENGLISH SUMMARY

Co-producing research with members of the public is increasingly recognised as a valuable process. Yet, despite these good intentions, the literature on coproduction has struggled to keep pace with the coproduction 'movement'. There is a lack of clarity regarding acceptable levels of involvement and attempts at standardising approaches appear generic and lack detail. Moreover, relatively little research has captured the views of all the parties involved (academics, service providers and service users).We conducted interviews with all those involved in developing a new online service for depression in Northern Ireland. Our main questions related to how these three very different groups of people worked together over a two-year period to design, develop and deliver the service (e.g. what were the benefits? What would they do differently?)We found that early involvement was a key factor as this promoted equal ownership. There was also a need to be flexible and recognise other workload pressures. Interestingly, service providers and service users were keen to become more involved in data analysis - this is one of the most under-researched and reported areas within the coproduction literature. Finally, we considered how user involvement worked within complex research designs and how this could be improved. Based on this learning, the paper concludes with a simple 3-step framework that others may wish to follow in order to improve coproduction outcomes within interventions.

ABSTRACT

Background Co-production, involving members of the public in research, is increasingly encouraged by research funders. However, reports detailing involvement of the public in the entire research process from design, delivery, analysis and dissemination of findings are lacking. Furthermore, little is known about the lessons learnt from the perspective of the public and researchers; or more specifically lessons learnt when coproducing specific types of research projects, such as feasibility/pilot studies incorporating a randomised controlled trial (RCT) design. This paper aims to provide a more rounded picture of co-production based on the learning outcomes of researchers, their community partners and service users involved in a feasibility/pilot RCT study developing and evaluating an E-health Service for adults with depression. Methods Qualitative research incorporating 11 semi-structured interviews with academic team members (n = 4), community partners (n = 3) and service users with depression (n = 4) Data were analysed using thematic analysis. Results Key factors for successful coproduction include - (1) early involvement at the pre-development stage, including contributing to the scientific grant application; (2) early identification of team strengths and expertise from the outset; (3) regular team meetings and contact (formal or informal) among coproduction partners; (4) a flexible and pragmatic approach to research design (particularly within RCTs); (5) shared decision making and responsibility and (6) recognition of 'other' pressures and providing support to each other. Findings also suggested further scope for involving community partners in data analysis and dissemination through co-authored papers. Those seeking to coproduce interventions or utilise RCT designs should consider tensions between data quality and intervention implementation and ethical issues regarding control groups. Conclusion This paper confirms previous research confirming the benefits of coproduction. However, it also highlights a number of barriers, particularly when using complex research design, such as RCTs. Learning points are summarised in an implementation model for coproducing research. This model may provide a useful guide for considering activities associated with meaningful coproduction. We urge others to test this proposed model more widely in different areas of coproduced research.

A critical realist evaluation of a music therapy intervention in palliative care

BACKGROUND

Music therapy is increasingly used as an adjunct therapy to support symptom management in palliative care. However, studies to date have paid little attention to the processes that lead to changes in patient outcomes. To fill this gap, we examined the processes and experiences involved in the introduction of music therapy as an adjunct complementary therapy to palliative care in a hospice setting in the United Kingdom (UK).

METHODS

Using a realistic evaluation approach, we conducted a qualitative study using a variety of approaches. These consisted of open text answers from patients (n = 16) on how music therapy helped meet their needs within one hospice in Northern Ireland, UK. We also conducted three focus groups with a range of palliative care practitioners (seven physicians, seven nursing staff, two social workers and three allied health professionals) to help understand their perspectives on music therapy's impact on their work setting, and what influences its successful implementation. This was supplemented with an interview with the music therapist delivering the intervention.

RESULTS

Music therapy contains multiple mechanisms that can provide physical, psychological, emotional, expressive, existential and social support. There is also evidence that the hospice context, animated by a holistic approach to healthcare, is an important facilitator of the effects of music therapy. Examination of patients' responses helped identify specific benefits for different types of patients.

CONCLUSIONS

There is a synergy between the therapeutic aims of music therapy and those of palliative care, which appealed to a significant proportion of participants, who perceived it as effective.

Costs of fragility hip fractures globally: a systematic review and meta-regression analysis

Purpose This study was conducted in order to systematically review the costs of hip fractures globally and identify drivers of differences in costs. Methods A systematic review was conducted to identify studies reporting patient level fragility hip fracture costs between 1990 and 2015. We extracted data on the participants and costs from these studies. Cost data concerning the index hospitalisation were pooled, and a meta-regression was used to examine its potential drivers. We also pooled data on the first-year costs following hip fracture and considered healthcare, social care as well as other cost categories if reported by studies. Results One hundred and thirteen studies reported costs of hip fracture based on patient level data. Patients developing complications as well as patients enrolled in intervention arms of comparative studies were found to have significantly higher costs compared to the controls. The pooled estimate of the cost for the index hospitalisation was $10,075. Health and social care costs at 12 months were $43,669 with inpatient costs being their major driver. Meta-regression analysis identified age, gender and geographic region as being significantly associated with the differences in costs for the index hospitalisation. Conclusion Hip fracture poses a significant economic burden and variation exists in their costs across different regions. We found that there was a considerable variation across studies in terms of study design, methodology, follow-up period, costs considered and results reported that highlights the need for more standardisation in this area of research.

Music therapy for children and adolescents with behavioural and emotional problems: a randomised controlled trial

BACKGROUND

Although music therapy (MT) is considered an effective intervention for young people with mental health needs, its efficacy in clinical settings is unclear. We therefore examined the efficacy of MT in clinical practice.

METHODS

Two hundred and fifty-one child (8-16 years, with social, emotional, behavioural and developmental difficulties) and parent dyads from six Child and Adolescent Mental Health Service community care facilities in Northern Ireland were randomised to 12 weekly sessions of MT plus usual care [n = 123; 76 in final analyses] or usual care alone [n = 128; 105 in final analyses]. Follow-up occurred at 13 weeks and 26 weeks postrandomisation. Primary outcome was improvement in communication (Social Skills Improvement System Rating Scales) (SSIS) at 13 weeks. Secondary outcomes included social functioning, self-esteem, depression and family functioning.

RESULTS

There was no significant difference for the child SSIS at week 13 (adjusted difference in mean 2.4; 95% CI -1.2 to 6.1; p = .19) or for the guardian SSIS (0.5; 95% CI -2.9 to 3.8; p = .78). However, for participants aged 13 and over in the intervention group, the child SSIS communication was significantly improved (6.1, 95% CI 1.6 to 10.5; p = .007) but not the guardian SSIS (1.1; 95% CI -2.9 to 5.2; p = .59). Overall, self-esteem was significantly improved and depression scores were significantly lower at week 13. There was no significant difference in family or social functioning at week 13.

CONCLUSIONS

While the findings provide some evidence for the integration of music therapy into clinical practice, differences relating to subgroups and secondary outcomes indicate the need for further study. ISRCTN Register; ISRCTN96352204.

The possibility of critical realist randomised controlled trials

Background

Some realists have criticised randomised controlled trials for their inability to explain the causal relations that they identify; to take into account the influence of the social context of the interventions they evaluate; and to account for individual difference. However, among realists, there is controversy over whether it is possible to improve trials by making them realist, or whether realism and the philosophical assumptions underlying trials are incompatible. This paper contributes to the debate in Trials on this issue. The debate thus far has concentrated on the possibility of combining trial methodology with that of realist evaluation.

Main body

We concur with the contention that it is not feasible to combine randomised controlled trial design with the realist evaluation approach. However, we argue that a different variant of realism, critical realism, provides a more appropriate theoretical grounding for realist trials.

In contrast to realist evaluation, which regards social mechanisms as an amalgam of social resources and people’s reasoning, critical realism insists on their distinction. It does so on the basis of its assertion of the need to distinguish between social structures (in which resources lie) and human agency (which is at least partly guided by reasoning). From this perspective, conceiving of social mechanisms as external to participants can be seen as a valid methodological strategy for supplementing the exclusive concentration of trials on outcomes.

While accepting realist evaluation’s insistence that causality in open systems involves a configuration of multiple generative mechanisms, we adopt the critical realist interpretation of the experimental method, which sees it as creating artificial closure in order to identify the effects of specific causal mechanisms. If randomised controlled trials can be regarded as epidemiological proxies that substitute probabilistic controls over extraneous factors for closed experiments, their examination of the powers of discrete mechanisms through observation of the variation of outcomes is appropriate.

Conclusion

While there are still issues to be resolved, critical realist randomised controlled trials are possible and have the potential to overcome some of the difficulties faced by traditional trial designs in accounting for the influence of social context and individual interpretation.

The experience of providing end of life care at a children's hospice: a qualitative study

Background

More attention is being paid to the wellbeing of staff working in stressful situations. However, little is known about staff experience of providing end-of-life care to children within a hospice setting. This study aims to explore the experiences of care team staff who provide end-of-life care within a children’s hospice.

Methods

Qualitative research incorporating interviews and a focus group. Data were analysed using thematic analysis. Purposeful sampling led to a total of 15 care team staff recruited from a children’s hospice offering palliative and specialist care to life-limited children and young people.

Results

The hospice setting provides a model of excellence in supporting staff and mitigating challenging aspects of their role, which includes peer/organisational support, and regular ongoing training in key aspects of children’s palliative care. Key recommendations for improving their experience included advanced communication training and knowledge sharing with other children’s palliative care specialists within the acute setting.

Conclusions

Service and policy initiatives should encourage open, informal peer/organisational support among the wider children’s palliative care sector. Further research should focus on paediatric palliative care education, particularly in relation to symptom management and communication at end-of-life, harnessing the expertise and breadth of knowledge that could be shared between children’s hospices and hospital settings.

Healthcare staff 's experience in providing end-of-life care to children: A mixed-method review

BACKGROUND

Staff who provide end-of-life care to children not only have to deal with their own sense of loss but also that of bereaved families. There is a dearth of knowledge on how they cope with these challenges.

AIM

The aim of this review is to explore the experiences of healthcare professionals who provide end-of-life care to children in order to inform the development of interventions to support them, thereby improving the quality of paediatric care for both children and their families.

DATA SOURCES

Searches included CINAHL, MEDLINE, Web of Science, EMBASE, PsychINFO and The Cochrane Library in June 2015, with no date restrictions. Additional literature was uncovered from searching reference lists of relevant studies, along with contacting experts in the field of paediatric palliative care.

DESIGN

This was a systematic mixed studies review. Study selection, appraisal and data extraction were conducted by two independent researchers. Integrative thematic analysis was used to synthesise the data.

RESULTS

The 16 qualitative, 6 quantitative and 8 mixed-method studies identified included healthcare professionals in a range of settings. Key themes identified rewards and challenges of providing end-of-life care to children, the impact on staff's personal and professional lives, coping strategies and key approaches to help support staff in their role.

CONCLUSION

Education focusing on the unique challenges of providing end-of-life care to children and the importance of self-care, along with timely multidisciplinary debriefing, are key strategies for improving healthcare staff's experiences, and as such the quality of care they provide.

Evaluation of the effectiveness of music therapy in improving the quality of life of palliative care patients: a randomised controlled pilot and feasibility study

BACKGROUND

Music therapy is frequently used as a palliative therapy. In consonance with the goals of palliative care, the primary aim of music therapy is to improve people's quality of life by addressing their psychological needs and facilitating communication. To date, primarily because of a paucity of robust research, the evidence for music therapy's effectiveness on patient reported outcomes is positive but weak. This pilot and feasibility study will test procedures, outcomes and validated tools; estimate recruitment and attrition rates; and calculate the sample size required for a phase III randomised trial to evaluate the effectiveness of music therapy in improving the quality of life of palliative care patients.

METHODS

A pilot randomised controlled trial supplemented with qualitative methods. The quantitative data collection will involve recruitment of >52 patients from an inpatient Marie Curie hospice setting over a 12-month period. Eligibility criteria include all patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 03- indicating they are medically fit to engage with music therapy and an Abbreviated Mental Test (AMT) score of ≥7 indicating they are capable of providing meaningful informed consent and accurate responses to outcome measures. Baseline data collection will include the McGill Quality of Life Questionnaire (MQOL); medical and socio-demographic data will be undertaken before randomisation to an intervention or control group. Participants in the intervention arm will be offered two 30-45 min sessions of music therapy per week for three consecutive weeks, in addition to care as usual. Participants in the control arm will receive care as usual. Follow-up measures will be administered in 1, 3 and 5 weeks. Qualitative data collection will involve focus group and individual interviews with HCPs and carers.

DISCUSSION

This study will ensure a firm methodological grounding for the development of a robust phase III randomised trial of music therapy for improving quality of life in palliative care patients. By undertaking the pilot and feasibility trial under normal clinical conditions in a hospice setting, the trial will result in reliable procedures to overcome some of the difficulties in designing music therapy RCTs for palliative care settings.

Music therapy for end-of-life care: An updated systematic review

BACKGROUND

Music therapy during palliative and end-of-life care is well established and positive benefits for patients have been reported.

AIM

Assess the effectiveness of music therapy versus standard care alone or standard care in combination with other therapies for improving psychological, physiological and social outcomes among adult patients in any palliative care setting.

DATA SOURCES

In order to update an existing Cochrane systematic review, we searched MEDLINE, CINAHL, EMBASE, PsycINFO, CENTRAL, ClinicalTrials.gov register and Current Controlled Trials register to identify randomised or quasi-randomised controlled trials published between 2009 and April 2015. Nine electronic music therapy journals were searched from 2009 until April 2015, along with reference lists and contact was made with key experts in music therapy. Only studies published in English were eligible for inclusion. Two reviewers independently screened titles, abstracts, assessed relevant studies for eligibility, extracted data and judged risk of bias for included studies. Disagreements were resolved through discussion with a third reviewer. Data were synthesised in Revman using the random effects model. Heterogeneity was assessed using I(2).

RESULTS

Three studies were included in the review. Findings suggest that music therapy may be effective for helping to reduce pain in palliative care patients (standard mean deviation = -0.42, 95% confidence interval = -0.68 to -0.17, p = 0.001).

CONCLUSION

Available evidence did not support the use of music therapy to improve overall quality of life in palliative care. While this review suggests that music therapy may be effective for reducing pain, this is based on studies with a high risk of bias. Further high-quality research is required.

Factors affecting the successful implementation and sustainability of the Liverpool Care Pathway for dying patients: a realist evaluation

OBJECTIVES

The Liverpool Care Pathway (LCP) for the dying patient was designed to improve end-of-life care in generalist healthcare settings. Controversy has led to its withdrawal in some jurisdictions. The main objective of this research was to identify the influences that facilitated or hindered successful LCP implementation.

METHOD

An organisational case study using realist evaluation in one health and social care trust in Northern Ireland. Two rounds of semistructured interviews were conducted with two policymakers and 22 participants with experience and/or involvement in management of the LCP during 2011 and 2012.

RESULTS

Key resource inputs included facilitation with a view to maintaining LCP 'visibility', reducing anxiety among nurses and increasing their confidence regarding the delivery of end-of-life care; and nurse and medical education designed to increase professional self-efficacy, and reduce misuse and misunderstanding of the LCP. Key enabling contexts were consistent senior management support; ongoing education and training tailored to the needs of each professional group; and an organisational cultural change in the hospital setting that encompassed end-of-life care.

CONCLUSIONS

There is a need to appreciate the organisationally complex nature of intervening to improve end-of-life care. Successful implementation of evidence-based interventions for end-of-life care requires commitment to planning, training and ongoing review that takes account of different perspectives, institutional hierarchies and relationships, and the educational needs of professional disciplines. There is a need also to recognise that medical consultants require particular support in their role as gatekeepers and as a lead communication channel with patients and their relatives.

Systematic realist review of key factors affecting the successful implementation and sustainability of the Liverpool care pathway for the dying patient

BACKGROUND

The Liverpool Care Pathway (LCP) is recommended internationally as a best practice model for the care of patients and their families at the end of life. However, a recent national audit in the United Kingdom highlighted shortcomings; and understanding is lacking regarding the processes and contextual factors that affect implementation.

AIM

To identify and investigate factors that help or hinder successful implementation and sustainability of the LCP.

METHODS

Electronic databases (Medline, CINAHL, British Nursing Index, Science Direct) and grey literature were searched, supplemented by citation tracking, in order to identify English language papers containing information relevant to the implementation of the LCP. Using a realist review approach, we systematically reviewed all relevant studies that focused on end of life care and integrated care pathway processes and identified theories that explained how the LCP and related programmes worked.

RESULTS

Fifty-eight papers were included in the review. Key factors identified were: a dedicated facilitator, education and training, audit and feedback, organisational culture, and adequate resources.

DISCUSSION

We discuss how these factors change behaviour by influencing the beliefs, attitudes, motivation and confidence of staff in relation to end of life care, and how contextual factors moderate behaviour change.

CONCLUSIONS

The implementation process recommended by the developers of the LCP is necessary but not sufficient to ensure successful implementation and sustainability of the pathway. The key components of the intervention (a dedicated facilitator, education and training, audit and feedback) must be configured to influence the beliefs of staff in relation to end of life care, and increase their motivation and self-efficacy in relation to using the LCP. The support of senior managers is vital to the release of necessary resources, and a dominant culture of cure, which sees every death as a failure, works against effective communication and collaboration in relation to the LCP.

Marginal plafond impaction in association with supination-adduction ankle fractures: a report of eight cases

In five years, approximately 800 ankle fractures were seen at the authors' institution, forty-four (5 percent) of which were of the supination-adduction pattern. Nineteen of these injuries had displaced vertical medial malleolus fractures, of which eight (42 percent) showed marginal impaction of the tibial plafond. All eight patients underwent open reduction and internal fixation with elevation of the impacted articular component and had good to excellent functional outcome with no arthritis on radiograph at the time of the most recent follow-up. The index of suspicion of marginal impaction of the tibial plafond should be high when treating supination-adduction pattern ankle fractures with displaced medial malleolus.

Tibial portal placement: the radiographic correlate of the anatomic safe zone

OBJECTIVE

To identify the radiographic correlate of the anatomic safe zone for tibial portal placement.

DESIGN

Cadaveric, anatomic, and radiographic study using twenty cadaveric knees. Kirschner wires were placed in the anatomic safe zone. Anteroposterior and lateral radiographs were taken to evaluate the portal placement.

SETTING

Anatomy laboratory.

OUTCOME MEASUREMENTS

Radiographic measurements of Kirschner wires placed in the anatomic safe zone.

RESULTS

The safe zone for tibial nail placement as seen on radiographs is just medial to the lateral tibial spine on the anteroposterior radiograph and immediately adjacent and anterior to the articular surface as visualized on the lateral radiograph. There is some variance on the anteroposterior radiograph but no variance on the lateral radiograph.

CONCLUSIONS

The placement of tibial nails in the superior portion of the tibia in the documented position generates the least risk to the intraarticular structures of the knee.

Isolated tibial shaft fracture

A nineteen-year-old otherwise healthy woman is seen in the emergency room after being struck by a car. The patient reports left lower extremity pain and has no other injuries. Exam shows a Tscherne grade I soft tissue injury with otherwise normal motor and sensory exam. There are no signs of compartment syndrome. A closed reduction was performed.

Acute myeloid leukemia in the elderly: assessment of multidrug resistance (MDR1) and cytogenetics distinguishes biologic subgroups with remarkably distinct responses to standard chemotherapy. A Southwest Oncology Group study

Compared with younger patients, elderly patients with acute myeloid leukemia (AML) respond poorly to conventional chemotherapy. To determine if this poor response is due to differences in the biologic characteristics of AML in the elderly, we studied 211 patients (161 de novo, 50 secondary AML) over 55 years of age (median, 68 years) registered to a single clinical trial for previously untreated AML (SWOG 9031, Phase III randomized trial of standard dose cytosine arabinoside and daunomycin + rhG-CSF). Pretreatment leukemic blasts were karyotyped and were also analyzed for intrinsic drug resistance by quantitating expression of the multidrug resistance glycoprotein MDR1 and functional drug efflux using sensitive flow cytometric techniques. Results were correlated with clinical variables and outcome. These elderly AML patients had a high frequency of unfavorable cytogenetics (32%), MDR1 protein expression (71%), and functional drug efflux (58%); each of these factors occurred at high frequencies in both de novo and secondary AML patients and was associated with a significantly poorer complete remission (CR) rate. In multivariate analysis, secondary AML (P = .0035), unfavorable cytogenetics (P = .0031), and MDR1 (P = .0041) were each significantly and independently associated with lower CR rates. Resistant disease was associated with unfavorable cytogenetics (P = .017) and MDR1 expression (P = .0007). Strikingly, elderly MDR1(-) de novo AML patients with favorable/intermediate cytogenetics had a CR rate of 81%; with increasing MDR1 expression, CR rate decreased in this cytogenetic group. MDR1(+) secondary AML patients with unfavorable cytogenetics had a CR rate of only 12%. Thus, AML in the elderly is associated with an increased frequency of unfavorable cytogenetics and MDR1 expression, both of which independently contribute to poor outcomes. The high frequencies of these features in both de novo and secondary elderly AML patients suggest a common biologic mechanism for these leukemias distinct from that in younger patients. Investigation of biologic parameters at diagnosis in AML in the elderly may help identify patients with a high likelihood of achieving CR with conventional regimens, as well as those who may require alternate regimens designed to overcome therapy resistance.

Must consent always be obtained for a do-not-resuscitate order?

Using cardiopulmonary resuscitation for cardiac or respiratory arrest unless there is an explicit do-not-resuscitate order is a policy adopted by all hospitals. Such a policy usually requires the patient's (or surrogate's) consent for a do-not-resuscitate order to be instituted. This article, however, presents the argument that consent need not always be obtained. In the case discussed, the well-being of the patient, other patients, and the health care providers all support a unilateral decision by the physician not to attempt resuscitation at the time of death. The medical community and society need to acknowledge that such cases exist and to develop policies that respect not only the interests of patients but also those of health care providers and society.

Multidrug resistance-1 (MDR1) expression and functional dye/drug efflux is highly correlated with the t(8;21) chromosomal translocation in pediatric acute myeloid leukemia

Resistance to chemotherapy is a major problem in acute myeloid leukemia (AML). An important resistance mechanism in adult AML is active drug efflux mediated by the multidrug resistance protein-1 (MDR1). To determine if MDR1 is important in childhood AML, we examined MDR1 expression and functional dye/drug efflux in 20 pediatric/adolescent AML patients; results were correlated with cytogenetics and clinical outcome. Using flow cytometry, MDR1 protein expression on the leukemic blasts was measured with the antibody MRK16, while efflux was measured by extrusion of the fluorescent dye DiO(C2)3 in the presence/absence of cyclosporin A (CsA). Six of 20 cases expressed MDR1. While all six MDR1+ cases were efflux+, three of 14 MDR1- cases also demonstrated efflux. Both MDR1 and efflux were strongly correlated with the t(8;21). All six MDR1 +/efflux+ cases and 2/3 MDR1 -/efflux+ cases had a t(8;21), while no MDR1-/efflux- cases had a t(8;21) (P < 0.0005). This correlation between MDR1, efflux, and the t(8;21) in pediatric AML was not found in 11 adult t(8;21) cases similarly studied. Although the clinical relevance of MDR1 in pediatric AML awaits larger studies, our results suggest a biologic subset of pediatric AML patients may benefit from regimens which include MDR1-reversing agents or non-MDR1 substrates.

Increase in enkephalin-like immunoreactivity in hippocampi of adults with generalized epilepsy

The changes of opioid peptide reactivity in seizure activity have been well studied in animals. Increased enkephalin and dynorphin immunoreactivity in the hippocampi of animals are interpreted as the result of seizure induced mossy fibre sprouting. We studied the hippocampi of six patients with a history of long-standing grand mal seizures and six age-matched control patients with no history of epilepsy or neurologic disease, using frozen sections which were immunostained with antibodies against Leu-enkephalin and Met-enkephalin. The staining intensity in the CA3, CA4 and internal molecular layer of the dentate fascia in each case was quantified using optical densitometry image analysis. The CA3 and CA4 of the epileptic hippocampi showed highly significant increase in Leu-enkephalin-like immunoreactivity compared to the controls (P < 0.005) while the inner molecular layer showed only significant increase (P < 0.05). Met-Enkephalin-like immunoreactivity was only significantly increased in CA4 of the epileptic hippocampi (P < 0.05).

Signet ring cell adenocarcinoma of prostate

Primary signet ring cell adenocarcinoma of the prostate is a rare malignancy with a total of 13 cases reported to date in the English literature. We report a very unusual case of signet ring adenocarcinoma of the prostate occurring in a patient who presented initially with irritative voiding symptoms and a bladder mass. Results of immunohistochemical, flow cytometric, and cytogenetic analyses of the tumor are presented.

Confidentiality and the law

Codes of medical ethics issued by professional organizations typically contain statements affirming the importance of confidentiality between patients and health-care practitioners. Seldom, however, is the confidentiality obligation depicted as absolute. Instead, exceptions are noted, the most common of which is that health-care professionals are justified in breaching the confidence of a patient if required by law to do so. Reasons that might be given to support this exception are critically discussed in this paper. The conclusion argued for is that this is not a legitimate exception to the confidentiality rule.

Dense microspheres in the human hippocampus

Dense microspheres (DMS) are structures found within neuronal processes of the adult human brain. Although best known as a feature of the neocortex, they are also found in the hippocampal formation. We describe a characteristic pattern of DMS distribution in the human hippocampus. The functional significance of this pattern is unknown, but it casts doubt on the proposed relationship of DMS to senile plaques. We also present evidence that DMS are composed of protein, but without a significant component of carbohydrate or neutral glycoprotein.

Prenatal diagnosis of transient myeloproliferative disorder via percutaneous umbilical blood sampling. Report of two cases in fetuses affected by Down's syndrome

Since its initial description in 1982, percutaneous umbilical blood sampling has become useful in diagnosing, monitoring, and even treating a variety of fetal disorders. Recently two percutaneous umbilical blood samples were evaluated in which the white blood cell count was markedly elevated with many circulating blasts. Both samples exhibited the morphologic features of a transient myeloproliferative disorder, characteristically seen in neonates and infants with Down's syndrome. In both cases, antenatal clinical and ultrasound abnormalities also were suggestive of Down's syndrome, which was confirmed by cytogenetic studies. Although the peripheral blood abnormalities persisted at birth, both patients experienced spontaneous remission of the transient myeloproliferative disorder by 5 weeks of age. To our knowledge, these two cases of Down's syndrome represent the first reported examples of the intrauterine diagnosis of transient myeloproliferative disorders.

Cloning and characterization of the t(15;17) translocation breakpoint region in acute promyelocytic leukemia

A reciprocal chromosomal translocation, t(15;17)(q22;q11.2-12), is characteristic of acute promyelocytic leukemia (APL) of French-American-British (FAB) subtype M3, and is not associated with any other human malignancy. The non-random pattern of the APL translocations suggests that specific genes on chromosomes 15 and 17 are somehow altered or deregulated as a consequence of the rearrangement. Translocation breakpoints in APL patients provide physical landmarks that suggest an approach to isolating the APL gene(s). Genetic and physical maps constructed for the APL breakpoint region on chromosome 17 have indicated that two fully-linked DNA markers, defining loci for THRA1 and D17S80, map to opposite sides of an APL breakpoint yet reside on a common 350-kb Clal fragment. Cosmid-walking experiments to clone this APL breakpoint have revealed a 38-kilobase deletion on chromosome 17. Studies in additional APL patients have shown that the breakpoint region on chromosome 17 spans at least 80 kilobases.

Megalencephaly in the epileptic chicken: a morphometric study of the adult brain

The epileptic chicken is a genetic model of generalized epilepsy in which epilepsy is combined with megalencephaly. We have performed a morphometric study of the brains of adult epileptic hens, using heterozygous carrier hens as controls. There is no obvious disorder of cell form or of architectural arrangement in the megalencephalic brains. We have found that the enlargement of the epileptic brain is not uniform: it is most marked in the telencephalon, and is present to a lesser degree in the cerebellum, but neither the optic tectum nor the diencephalic nucleus rotundus shows a significant increase in size. The enlarged regions are characterized by a decrease in the packing density of neurons. There is an increase in the total neuron population in some of the enlarged areas (archistriatum), despite the lower density per unit volume, but in other enlarged areas (hippocampus) there is no difference in total neuron numbers. The glial cells, by contrast, show no significant alteration in packing density. These findings suggest that the megalencephaly of the epileptic chicken is due to an increase in neuron size, with a contribution from increased numbers of neurons and glial cells. The epileptic chicken may provide a valuable model for further dynamic studies of aberrant neuronal development, and of structural-functional relationships in epilepsy.
