The methodological quality of systematic reviews regarding the Core Outcome Set (COS) development

BACKGROUND

The Core Outcome Measures in Effectiveness Trials (COMET) working group proposed core outcome sets (COS) to address the heterogeneity in outcome measures in clinical studies. According to the recommendations of COMET, performing systematic reviews (SRs) usually was the first step for COS development. However, the SRs that serve as a basis for COS are not specifically appraised by organizations such as COMET regarding their quality. Here, we investigated the status of SRs related to development of COS and evaluated their methodological quality.

METHODS

We conducted a search on PubMed to identify SRs related to COS development published from inception to May 2022. We qualitatively summarized the disease included in SR topics, and the studies included in the SRs. We evaluated the methodological quality of the SRs using AMSTAR 2.0 and compared the overall quality of SRs with and without protocols using the Mann-Whitney U test.

RESULTS

We included 175 SRs from 23 different countries or regions, and they mainly focused on five diseases: musculoskeletal system or connective tissue disease (n = 19, 10.86%), injury, poisoning, or certain other consequences of external causes (n = 18, 10.29%), digestive system disease (n = 16, 9.14%), nervous system disease (n = 15, 8.57%), and genitourinary system disease (n = 15, 8.57%). Although 88.00% of SRs included randomized controlled trials (RCTs), only a few SRs (23.38%) employed appropriate tools to assess the risk of bias in RCTs. The assessment results on the basis of AMSTAR 2.0 indicated that most SRs (93.71%) were rated as ''critically low'' to ''low'' in terms of overall confidence. The overall confidence of SRs with protocols was significantly higher than that without protocols (P <.001). Compared to the SRs with protocols on Core Outcome Measures in Effectiveness Trials (COMET), SRs with protocols on PROSPERO were of better overall confidence (P = .017).

CONCLUSION

The overall quality of published SRs regarding COS development was poor. Our findings emphasize the need for researchers to carefully select the disease topic and strictly adhere to the requirements of optimal methodology when conducting a SR for the establishment of a COS.

Qualified and motivated, but limited by specialty-specific barriers: a national survey of UK Palliative Medicine consultants research experience

OBJECTIVES

Providing high-quality safe palliative care requires high-quality clinically driven research. Little is known about how to optimise clinical research capacity in this field.To understand interest and capacity to conduct clinical research in palliative medicine and identify key facilitators and barriers, by surveying palliative medicine consultants and academic trainees.

METHODS

National online survey exploring experience in conducting research, including facilitators and barriers. Sent to all current UK palliative medicine consultants, and previous/current academic trainees. Descriptive statistics are reported with framework analysis of free text responses.

RESULTS

195 surveys were submitted including 15 respondents with Integrated Academic Training (IAT) experience. 78% (n=140/180) of consultants were interested in conducting research. Despite this enthusiasm, 83% had no allocated time within their job plan. 88% of those who undertook IAT would recommend IAT, but 60% reported difficulty transitioning from academic trainee to research active consultant.Barriers to research included; insufficient research culture and integration, with small teams working in a mixture of National Health Service (NHS) and non-NHS settings, leading to isolated, silo working. Even those who had undertaken IAT, felt a 'cliff edge' in opportunities after completing IAT. Filling service gaps was routinely prioritised over research activity.

CONCLUSION

Palliative medicine consultants, including those who have completed academic training want to conduct research but overwhelming barriers limit activity. A palliative care-specific strategy that permeates different palliative care settings, promotes interspecialty collaboration and improves the current infrastructure for palliative care research to maximise gains from IAT and embed a research culture are suggested.

Palliative radiotherapy: survival prognostic factors - single-centre retrospective cohort study

OBJECTIVE

Patients with non-curative malignancy can receive palliative radiotherapy (PR) to alleviate symptoms. However, choosing the right patient to receive PR can be challenging, as some patients may not survive long enough to gain benefit. This study aims to identify prognostic factors for overall survival (OS) and 30-day mortality (30DM) following PR and to test these in a real-world cohort.

METHOD

A retrospectively collected data set of all adults completing PR between 1 August 2018 and 31 December 2018 at a single centre (n=214, Southend University Hospital NHS Foundation Trust, UK) was used to test prognostic factors. Factors such as demographics, tumour primary, treatment area, fractionation regime, performance status (PS), progressive disease (PD), opioid or steroid use and haemoglobin level, as well as overall survival, were collected. Cox regression was used to examine survival predictors, and logistic regression was used to determine the predictive strength of factors for 30DM.

RESULTS

Overall 30DM was 14%. There was significantly worse survival in patients with poor PS (HR 1.2406, 95% CI 0.94 to 1.64. p=0.01). Patients with PS 3 had a median OS of 75 days and were more likely to experience 30DM (OR 6.2, 95% CI 1.226 to 45.42, p=0.03). Patients with PD outside of the radiation field (46%, 30 out of 65 documented) had significantly worse OS (HR 5.24, 95% CI 2.19 to 12.5, p<0.001).

CONCLUSION

Poor PS and PD were prognostic of OS and 30DM. Future work should include validation with a prospectively collected cohort.

Digital health and inpatient palliative care: a cohort-controlled study

OBJECTIVES

End of life has unacceptable levels of hospital admission and death. We aimed to determine the association of a novel digital specific system (Proactive Risk-Based and Data-Driven Assessment of Patients at the End of Life, PRADA) to modify such events.

METHODS

A cohort-controlled study of those discharged alive, who died within 90 days of discharge, comparing PRADA (n=114) with standard care (n=3730).

RESULTS

At 90 days, the PRADA group were more likely to die (78.9% vs 46.2%, p<0.001), had a shorter time to death (58±90 vs 178±186 days, p<0.001) but readmission (20.2% vs 37.9%, p<0.001) or death in hospital (4.4% vs 28.9%, p<0.001) was lower with reduced risk for a combined 90-day outcome of postdischarge non-elective admission or hospital death (OR 0.45, 95% CI 0.27-0.74, p<0.001). Tightening criteria with 1:1 matching (n=83 vs 83) showed persistent significant findings in PRADA contact with markedly reduced adverse events (OR 0.15, 95% CI 0.02-0.96, p<0.05).

CONCLUSIONS

Being seen in hospital by a specialist palliative care team using the PRADA tool was associated with significantly improved postdischarge outcomes pertaining to those destined to die after discharge.

Palliative care inpatients favour research participation irrespective of prognosis, performance or socioeconomic status: multicentre cohort study

OBJECTIVES

Palliative care needs to embrace research to guide service development and effective symptom management. Healthcare professionals often feel research is too burdensome for patients who have poor performance status or are near the end of life. Many studies exclude these groups from participating.We aimed to identify whether specialist palliative care inpatients would wish to take part in research and whether preference varies according to study design, demographics, diagnosis, performance status and prognosis.

METHODS

100 inpatients in two National Health Service specialist palliative care units and one independent hospice in the Northeast of England completed a short questionnaire about preferences for involvement in research.

RESULTS

92% of participants stated they were interested in being involved in research. This was mostly unaffected by age, diagnosis, prognosis, performance and socioeconomic status. Three-quarters were within the last 3 months of life. Simple questions or interviews were the preferred methodology, whereas only half of patients would want further investigations or additional medications and fewer still wanted to participate in online activities, lifestyle change or group activities.

CONCLUSIONS

Palliative care inpatients welcome the opportunity to be involved in research and should not be excluded on the grounds of advanced disease, poor prognosis and low performance status.

End of life in general practice: trends 2009-2019

OBJECTIVES

To assess possible trends between 2009 and 2019 in the Netherlands of palliative care indicators: the provision of palliative care or treatment, hospitalisations in the last month before death, use of specialised palliative care services and place of death.

METHODS

The study design was a repeated retrospective cross-sectional design with questionnaires filled in by general practitioners within a clustered sample of 67 Sentinel practices. Patients whose death was non-sudden, and thus could have received palliative care, between 1 January 2009 and 31 December 2019 were included in the study, resulting in 3121 patients.

RESULTS

Between 2009 and 2019, there is a significant increase in the number of people who receive palliative care or treatment alongside life-prolonging or curative treatment and the number of people who die at home, while the number of hospitalisations in the last month before death and the number of people dying in hospital shows a significant decrease. However, there is no trend in the involvement of specialised palliative care services or people receiving solely palliative care or treatment.

CONCLUSION

This study suggests improvements in end-of-life care provided in primary care in the Netherlands. Trends coincided with increased attention to palliative care both in practice and policy. Yet, there is still considerable room for improvement as there is no significant increase in people solely receiving palliative care or treatment and the involvement of specialised palliative care services.

End-of-life care quality measures: beyond place of death

BACKGROUND

How quality in healthcare is measured shapes care provision, including how and what care is delivered. In end-of-life care, appropriate measurement can facilitate effective care and research, and when used in policy, highlight deficits and developments in provision and endorse the discipline necessity. The most prevalent end-of-life quality metric, place of death, is not a quality measure: it gives no indication of the quality of care or patient experience in the place of death.

AIM

To evaluate alternative measures to place of death for assessing quality of care in end-of-life provision in all settings.

METHOD

We examine current end-of-life care quality measures for use as metrics for quality in end-of-life care. We categorise approaches to measurement as either: clinical instruments, mortality follow-back surveys or organisational data. We review each category using four criteria: care setting, patient population, measure feasibility, care quality.

RESULTS

While many of the measure types were highly developed for their specific use, each had limitations for measuring quality of care for a population. Measures were deficient because they lacked potential for reporting end-of-life care for patients not in receipt of specialist palliative care, were reliant on patient-proxy accounts, or were not feasible across all care settings.

CONCLUSION

None of the current end-of-life care metric categories can currently be feasibly used to compare the quality of end-of-life care provision for all patients in all care settings. We recommend the development of a bespoke measure or judicious selection and combination of existing measures for reviewing end-of-life care quality.

Inconsistent views among systematic review authors toward publishing protocols as peer-reviewed articles: an international survey

OBJECTIVES

This study aimed to explore views of authors of systematic reviews (SRs) registered in the International Prospective Register of Systematic Reviews (PROSPERO) toward publishing SR protocols as peer-reviewed articles.

STUDY DESIGN AND SETTING

Contact persons of all PROSPERO records for non-Cochrane SRs registered in 2018 (N = 12,531) were invited to participate in an anonymous 5-minute online survey that was administered through SurveyMonkey. The main question addressed SR authors' views toward publishing SR protocols as peer-reviewed articles. Data were analyzed descriptively.

RESULTS

In total, 4,223 (33.7%) of 12,531 invitees responded, of which 3,739 (88.5%) completed the survey. Almost half of the international respondents had published or planned to publish a protocol for the SR described in their PROSPERO record as a peer-reviewed article (1,811/4,054; 44.7%). Most respondents agreed that publishing a protocol in a peer-reviewed journal increases SR quality as reviewers get external feedback from peer reviewers (2,899/3,739; 77.5%) but at the same time agreed that it is not necessary if the SR is registered in PROSPERO (2,399/3,739; 64.2%).

CONCLUSION

SR authors seem to have inconsistent views toward publishing protocols as peer-reviewed articles, and many seem to consider registration in PROSPERO (without peer review) sufficient. Hence, awareness about the benefits of publishing protocols as a peer-reviewed article in addition to registration in PROSPERO should be raised.

An international, Delphi consensus study to identify priorities for methodological research in behavioral trials in health research

Background

Non-communicable chronic diseases are linked to behavioral risk factors (including smoking, poor diet and physical inactivity), so effective behavior change interventions are needed to improve population health. However, uptake and impact of these interventions is limited by methodological challenges. We aimed to identify and achieve consensus on priorities for methodological research in behavioral trials in health research among an international behavioral science community.

Methods

An international, Delphi consensus study was conducted. Fifteen core members of the International Behavioral Trials Network (IBTN) were invited to generate methodological items that they consider important. From these, the research team agreed a “long-list” of unique items. Two online surveys were administered to IBTN members (N = 306). Respondents rated the importance of items on a 9-point scale, and ranked their “top-five” priorities. In the second survey, respondents received feedback on others’ responses, before rerating items and re-selecting their top five.

Results

Nine experts generated 144 items, which were condensed to a long-list of 33 items. The four most highly endorsed items, in both surveys 1 (n = 77) and 2 (n = 57), came from two thematic categories:“Intervention development” (“Specifying intervention components” and “Tailoring interventions to specific populations and contexts”) and “Implementation” (“How to disseminate behavioral trial research findings to increase implementation” and “Methods for ensuring that behavioral interventions are implementable into practice and policy”). “Development of novel research designs to test behavioral interventions” also emerged as a highly ranked research priority.

Conclusions

From a wide array of identified methodological issues, intervention development, implementation and novel research designs are key themes to drive the future behavioral trials’ research agenda. Funding bodies should prioritize these issues in resource allocation.

Can learning about trials be child's play? A qualitative exploration of the 'Schools Teaching Awareness of Randomised Trials' (START) initiative

Background

The Health Research Board-Trials Methodology Research Network (HRB-TMRN) celebrates International Clinical Trials Day with the help of the younger members of our community through the Network’s ‘Schools Teaching Awareness of Randomised Trials (START)’ initiative. START seeks to increase public awareness of randomised trials in Ireland. Launched in 2016, it asks children (8–12 years old) to conduct and report their very own fun randomised trial. The study reported in this paper sought to explore children and teachers perceptions and experiences of the START initiative.

Methods

We conducted eight, one-to one interviews with teachers and eight focus groups with 61 children who took part in the 2018 START initiative. Interviews and focus groups were recorded and transcribed and the data analysed using template analysis.

Results

The findings of this study highlight the benefits of participating in START and the areas of the initiative that required further attention. Teachers and children recalled the benefits of experiential learning associated with START and learning by doing encouraged a fun way of engaging with trial processes. By recalling all aspects of planning, conducting and reporting their trial, the children in this study demonstrated their awareness of the trial processes. The teachers suggested that START provides a valuable framework to contribute to key aspects of the primary school curriculum in Ireland. The experiences of these participants also provided recommendation for improving the programme for future START participants.

Conclusions

Increasing public awareness and understanding of randomised trials can help increase public engagement in trials. By educating children about the importance of trials and supporting them to ‘learn by doing’ by carrying out their own trial, the START initiative can contribute substantially to children’s awareness and understanding of trial processes. Given that children are the public, the patients and the researchers of the future, initiatives such as START deserve attention.

A review of current practice in the design and assessment of internal pilots in UK NIHR clinical trials

Background

Internal pilots provide useful information which can help to optimise the running of the main trial. Although some recommendations exist in the literature for the design of internal pilots, little is known about current practice in terms of the specification and also the assessment of progression criteria. The aim of the review is to provide an overview of current practice.

Methods

A cohort of clinical trials with an internal pilot, funded by the National Institute for Health Research (NIHR), Health Technology Assessment programme (HTA), extracted in 2017 was reviewed. Data were extracted from: project descriptions; summary of changes from the first stage; feedback about the full application; monitoring notes; progress report history and protocols, for information about the design and assessment of internal pilots.

Results

Fifty-seven studies were reviewed. An internal pilot was first proposed in the early stages of the trial in the majority of cases. Target number for recruitment, rate of randomisation, retention/primary outcome ascertainment rate, rate of treatment adherence and consent rate were included as progression criteria. All but one study was permitted to continue to the main trial; however, 25% did not strictly meet the progression criteria. Changes were made to the design of the main trial for 25% of studies, mainly in terms of conduct of recruitment.

Conclusions

This review provides insight into the process of designing and assessing internal pilots. Progression criteria are sometimes not met; however, committees involved in the reviewing process will recommend continuation to the main trial, usually accompanied by a second review or close monitoring. Recommendations are made to optimise the process.

Considerations and recommendations for conducting qualitative research interviews with palliative and end-of-life care patients in the home setting: a consensus paper

OBJECTIVES

To present and discuss the views of researchers at an academic palliative care research centre on research encounters with terminally ill patients in the home setting and to generate a list of recommendations for qualitative researchers working in palliative and end-of-life care.

METHODS

Eight researchers took part in a consensus meeting to discuss their experiences of undertaking qualitative interviews. The researchers were of varying backgrounds and all reported having experience in interviewing terminally ill patients, and all but one had experience of interviewing patients in their home environment.

RESULTS

The main areas discussed by researchers included: whether participation in end-of-life research unintentionally becomes a therapeutic experience or an ethical concern; power relationships between terminally ill patients and researchers; researcher reflexivity and reciprocity; researchers' training needs. Qualitative methods can complement the home environment; however, it can raise ethical and practical challenges, which can be more acute in the case of research undertaken with palliative and patients at the end-of-life.

CONCLUSIONS

The ethical and practical challenges researchers face in this context has the potential to place both participant and researcher at risk for their physical and psychological well-being. We present a set of recommendations for researchers to consider prior to embarking on qualitative research in this context and advocate researchers in this field carefully consider the issues presented on a study-by-study basis.

Sociodemographic differences in linkage error: an examination of four large-scale datasets

BACKGROUND

Record linkage is an important tool for epidemiologists and health planners. Record linkage studies will generally contain some level of residual record linkage error, where individual records are either incorrectly marked as belonging to the same individual, or incorrectly marked as belonging to separate individuals. A key question is whether errors in linkage quality are distributed evenly throughout the population, or whether certain subgroups will exhibit higher rates of error. Previous investigations of this issue have typically compared linked and un-linked records, which can conflate bias caused by record linkage error, with bias caused by missing records (data capture errors).

METHODS

Four large administrative datasets were individually de-duplicated, with results compared to an available 'gold-standard' benchmark, allowing us to avoid methodological issues with comparing linked and un-linked records. Results were compared by gender, age, geographic remoteness (major cities, regional or remote) and socioeconomic status.

RESULTS

Results varied between datasets, and by sociodemographic characteristic. The most consistent findings were worse linkage quality for younger individuals (seen in all four datasets) and worse linkage quality for those living in remote areas (seen in three of four datasets). The linkage quality within sociodemographic categories varied between datasets, with the associations with linkage error reversed across different datasets due to quirks of the specific data collection mechanisms and data sharing practices.

CONCLUSIONS

These results suggest caution should be taken both when linking younger individuals and those in remote areas, and when analysing linked data from these subgroups. Further research is required to determine the ramifications of worse linkage quality in these subpopulations on research outcomes.

Evaluation of methods used for estimating content validity

The assessment of content validity is a critical and complex step in the development process of instruments which are frequently used to measure complex constructs in social and administrative pharmacy research. The aims of this study were to investigate the elements of content validity; to describe a practical approach for assessing content validity; and to discuss existing content validity indices. This is a narrative review of the assessment and quantification of content validity. It describes the key stages of conducting the content validation study and discusses the quantification and evaluation of the content validity estimates. Content validity provides evidence about the degree to which elements of an assessment instrument are relevant to and representative of the targeted construct for a particular assessment purpose. The assessment of content validity relies on using a panel of experts to evaluate instrument elements and rate them based on their relevance and representativeness to the content domain. It is a three-stage process that includes; the development stage, judgment and quantifying stage, and revising and reconstruction stage. To quantify the expert judgments, several indices have been discussed in this paper such as the content validity ratio (CVR), content validity index (CVI), modified-Kappa, and some agreement indices. A practical guide describes the process of content validity evaluation is provided. In summary, content validation processes and content validity indices are essential factors in the instrument development process, should be treated and reported as important as other types of construct validation. Determining item CVI and reporting an overall CVI are important components necessary to instruments especially when the instrument is used to measure health outcomes or to guide a clinical decision making. Content validity deserves a rigorous assessment process as the obtained information from this process are invaluable for the quality of the newly developed instrument.

Preparing future doctors for palliative care: views of course organisers

BACKGROUND

Effective training at medical school is essential to prepare new doctors to safely manage patients with palliative care (PC) and end of life care (EOLC) needs. The contribution of undergraduate PC course organisers is central but their collective views regarding role are unknown.

OBJECTIVE

To survey attitudes of PC course organisers regarding their course, organisation, the adequacy of training provided and level of personal satisfaction.

METHODS

An anonymised, multifactorial, web-based questionnaire was devised, tested, modified and then sent to lead PC course organisers at all UK medical schools.

RESULTS

Data were obtained from all 30 UK medical schools. Organisers agreed/strongly agreed (=agreed) that their PC course was highly rated by students (26, 87%). 25 (83%) agreed their course 'enabled misconceptions and fears about PC, death, dying and bereavement to be addressed', 'delivered quality PC training' (23, 77%), 'fulfilled General Medical Council requirements' (19, 63%), 'prepared students well to care for patients with PC/EOLC needs' (18, 60%) and 'enabled students to visit a hospice and see the role of doctors in caring for the dying' (17, 57%). Concerns were limited capacity to accommodate students (agreed 20, 66%) and variability in teaching according to location (15, 50%). Most agreed their institution recognised PC training as important (22, 73%), they felt supported by colleagues (21, 70%) and experienced cooperation between stakeholders (20, 67%). All agreed that PC training was essential for undergraduates, while 29 (97%) supported inclusion of a hospice visit in the curriculum. 27 agreed that their role was satisfying (90%), 3 disagreed (10%).

CONCLUSIONS

Approximately two-thirds of organisers were generally positive about their PC course, institution and role. A minority expressed concerns; these may reflect suboptimal PC training at their medical school and poor preparation of new doctors.

Internet search query analysis can be used to demonstrate the rapidly increasing public awareness of palliative care in the USA

BACKGROUND

A lack of public awareness of palliative care (PC) has been identified as one of the main barriers to appropriate PC access. Internet search query analysis is a novel methodology, which has been effectively used in surveillance of infectious diseases, and can be used to monitor public awareness of health-related topics.

OBJECTIVES

We aimed to demonstrate the utility of internet search query analysis to evaluate changes in public awareness of PC in the USA between 2005 and 2015.

METHODS

Google Trends provides a referenced score for the popularity of a search term, for defined regions over defined time periods. The popularity of the search term 'palliative care' was measured monthly between 1/1/2005 and 31/12/2015 in the USA and in the UK.

RESULTS

Results were analysed using independent t-tests and joinpoint analysis. The mean monthly popularity of the search term increased between 2008-2009 (p<0.001), 2011-2012 (p<0.001), 2013-2014 (p=0.004) and 2014-2015 (p=0.002) in the USA. Joinpoint analysis was used to evaluate the monthly percentage change (MPC) in the popularity of the search term. In the USA, the MPC increase was 0.6%/month (p<0.05); in the UK the MPC of 0.05% was non-significant.

DISCUSSION

Although internet search query surveillance is a novel methodology, it is freely accessible and has significant potential to monitor health-seeking behaviour among the public. PC is rapidly growing in the USA, and the rapidly increasing public awareness of PC as demonstrated in this study, in comparison with the UK, where PC is relatively well established is encouraging in increasingly ensuring appropriate PC access for all.

Exploring the association of hospice care on patient experience and outcomes of care

OBJECTIVE

To examine the association of the use of hospice care on patient experience and outcomes of care. Promoting high-value, safe and effective care is an international healthcare imperative. However, the extent to which hospice care may improve the value of care is not well characterised.

METHODS

A secondary analysis of variations in care was conducted using the Dartmouth Atlas Report, matched to the American Hospital Association Annual Survey Database to abstract organisational characteristics for 236 US hospitals to examine the relationship between hospice usage and a number of variables that represent care value, including hospital care intensity index, hospital deaths, intensive care unit (ICU) deaths, patient satisfaction and a number of patient quality indicators. Structural equation modelling was used to demonstrate the effect of hospice use on patient experience, clinical and efficiency outcomes.

RESULTS

Hospice admissions in the last 6 months of life were correlated with a number of variables, including increases in patient satisfaction ratings (r=0.448, p=0.01) and better pain control (r=0.491, p=0.01), and reductions in hospital days (r=-0.517, p=0.01), fewer hospital deaths (r=-0.842, p=0.01) and fewer deaths occurring with an ICU admission during hospitalisation (r=-0.358, p=0.01). The structural equation model identified that use of hospice care was inversely related to hospital mortality (-0.885) and ICU mortality (-0.457).

CONCLUSIONS

The results of this investigation demonstrate that greater use of hospice care during the last 6 months of life is associated with improved patient experience, including satisfaction and pain control, as well as clinical outcomes of care, including decreased ICU and hospital mortality.

Patient and public involvement in research and the Cancer Experiences Collaborative: benefits and challenges

AIMS AND OBJECTIVES

The involvement of patients in the design and conduct of research is increasingly promoted by policy and research bodies. The experiences of individuals who become involved in research in this way are not well understood. This study aims to describe the experiences of people's participation in patient and public involvement (PPI) in supportive and palliative care research, specifically with respect to the benefits and challenges of participation for the individuals and the broader research support structures.

METHODS

In this qualitative exploratory study, semistructured interviews were undertaken with individuals who had a cancer diagnosis and were involved in a supportive and palliative care research collaborative over a period of 6 years. Recruitment was through the host university organisations involved in the research collaborative. A thematic analysis was undertaken to identify commonalities and differences across their experiences.

FINDINGS

The eight participants in the study were highly motivated and undertook PPI in research alongside other voluntary activities. They identified a number of research and personal benefits: bringing a lay perspective into research, making a difference and personal gains. Personal gains concerned support, new knowledge and skills and greater confidence. The challenges to participation that were identified included the emotional and practical nature of the work, issues of language and identifying the difference made.

CONCLUSIONS

Involvement in supportive and palliative care research is valued by people with a cancer diagnosis, but there are ongoing issues of emotional support and good communication through the use of appropriate language in documentation.

Methodological aspects in the assessment of safety culture in the hospital setting: a review of the literature

A thematic literature review was undertaken to identify methodological aspects in the assessment of safety culture and critically examine how these have been addressed in hospital-based studies of safety culture, for the period 1999-2012. The literature search included an electronic database search (BNI, CINAHL, EMBASE, MEDLINE and PsycINFO), access to websites of organizations dedicated to the enhancement of patient safety, and a manual search of reference lists of the papers included. The analysis of the 43 records included in the review revealed that discussion regarding the measurement of safety culture in the hospital setting revolves around three methodological areas, namely: research approaches; survey tools for data collection; and levels of data aggregation. To advance these discussions, robust research is needed to clarify what dimensions belong to the core of safety culture and what the main sources of safety culture variability are. Studies using a mixed methods approach to assess safety culture would be useful, since they permit the in-depth research necessary to depict the multiple components of this construct.

Development and initial validation of a new outcome measure for hospice and palliative care: the St Christopher's Index of Patient Priorities (SKIPP)

OBJECTIVE

To develop and conduct a preliminary psychometric analysis of a hospice and palliative care patient-reported outcome measure to detect patients' perceptions of change in quality of life (QoL) and issues of concern, and views of service benefit.

METHODS

Following pilot testing and cognitive interviewing, St Christopher's Index of Patient Priorities (SKIPP) was administered twice to hospice inpatients and homecare patients. QoL was rated 'now', and retrospectively 'before starting hospice care' or 'at the time of the first interview'. Patients nominated and rated progress with main concerns, rated the difference the service was making, and completed palliative care outcome scale. Patients completed SKIPP again within 24 h to measure test-retest reliability.

RESULTS

QoL scores 'now' differed significantly from retrospective scores made at same time: QoL increased with hospice care when patients 'looked back' on previous QoL. Four-fifths reported that their first concern had got 'a little'/ 'much' better since initial service contact: this declined subsequently. Four-fifths at both time points said the hospice had made 'a lot of difference' to them. No significant differences were noted between time points on palliative care outcome scale items. Test-retest analyses were prevented by low numbers.

CONCLUSIONS

SKIPP can detect patients' perception of change in QoL and main concerns, and the difference patients think the service has made to them. Its design with current and retrospective components addresses response shift and means it can be used for quality improvement or clinical purposes with only one administration, an advantage in frail populations. It is therefore a useful addition to hospice and palliative care patient-reported outcome measures.

Barriers to research in palliative care in France

PURPOSE

Palliative care (PC) needs expansion of its research capacity to improve the quality of care. This is particularly true for France that contributed less than 2% of all European PC research publications. We conducted a survey to assess the barriers French healthcare professionals (HCPs) involved in PC research had to face.

METHODS

We surveyed all 420 PC departments registered in the French National Association for Palliative Care (SFAP) database using a previously used questionnaire. We documented the ethical limitations, time constraints, financial resources, patient issues and methodological issues related to PC research.

RESULTS

We obtained 382 responses. Ninety-two (24.1%) HCPs were involved in a research project during the last 5 years. In univariate results, predictors of being involved in PC research were men (p=0.004), physician (p=0.022), working at a university hospital (p<0.001). There was a trend towards working in a PC unit (p=0.052). The main barriers to participating in PC research were lack of time (80.1%) and patient issues (47.4%). Lack of methodological support (33.0%) and financial limitations (30.4%) were also reported as major barriers.

CONCLUSIONS

There is a consensus that PC research and publication in the English language for peer-reviewed journals must be expanded in France but at this stage, clinical teams still lack specific funding and appropriate support. More research is needed to confirm our results and to determine the best ways to develop PC research capacity in France.
