Working together: Crossing discipline boundaries to evaluate complex interventions

Nurses, it is argued, should participate in interdisciplinary research, yet there is little written about working in an interdisciplinary environment in research. This paper sets out some reflections on the experience of a nurse and a health economist working together on a series of studies. A number of difficulties are identified as themes running through the experience of interdisciplinary research: evaluating complex interventions, disruption of normal academic and scientific life, competition between disciplines and teams, finding a common language and learning to work together, finding the common ground and mutual self-interest, and learning to respect other perspectives and disciplines. Rosenfield's (1992) taxonomy of cross-disciplinary research is presented as a model to explain the development of our own approach. A commitment to the goal of transdisciplinarity in research is suggested.

Working with resistance, tension and objectivity: Conducting a randomised controlled trial of a nursing intervention for breathlessness

It is vital that nurses wishing to recommend or introduce new strategies are able to provide supporting evidence that is acceptable to their colleagues. The methodology from which to derive such evidence remains to be clearly defined, as the research process is complex, demanding and, to a certain extent, uncharted. This paper examines the experience of nurses collaborating in a multi-centre randomised controlled trial which evaluated a nursing intervention for the management of breathlessness in patients with lung cancer. The study raised several important methodological issues: resistance among colleagues to innovative nursing practice; the difficulty of measuring well-being in patients whose physical condition is deteriorating; maintaining uniformity of practice within a diverse group of collaborating nurse researchers; and the tension between the nursing role and the necessity of an ethically demanding research design.

Analysis of the process of conducting a randomised controlled trial produced valuable insights which indicated the kind of support required to undertake research and successfully implement a new intervention into clinical practice. The study also highlighted the problems associated with asking ill people to complete standard measurement tools, particularly when such instruments might not be sensitive to the reality of the patient(s) problem, in this case, the experience of breathlessness.

A web-based intervention (RESTORE) to support self-management of cancer-related fatigue following primary cancer treatment: a multi-centre proof of concept randomised controlled trial

PURPOSE

Cancer-related fatigue (CRF) is a frequent and distressing symptom experienced after cancer treatment. RESTORE is the first web-based resource designed to enhance self-efficacy to manage CRF following curative-intent treatment. The aim of this study is to test the proof of concept and inform the design of an effectiveness trial.

METHODS

A multi-centre parallel-group two-armed (1:1) exploratory randomised controlled trial (RCT) with qualitative process evaluation was employed in the study. Participants (≥18 years; ≤5 years post treatment with moderate to severe fatigue) were recruited and randomly assigned to RESTORE or a leaflet. Feasibility and acceptability were measured by recruitment, attrition, intervention adherence, completion of outcome measures and process evaluation. Change in self-efficacy to manage CRF was also explored. Outcome measures were completed at baseline (T0), 6 weeks (T1) and 12 weeks (T2). Data were analysed using mixed-effects linear regression and directed content analysis.

RESULTS

One hundred and sixty-three people participated in the trial and 19 in the process evaluation. The intervention was feasible (39 % of eligible patients consented) and acceptable (attrition rate 36 %). There was evidence of higher fatigue self-efficacy at T1 in the intervention group vs comparator (mean difference 0.51 [-0.08 to 1.11]), though the difference in groups decreased by 12 weeks. Time since diagnosis influenced perceived usefulness of the intervention. Modifications were suggested.

CONCLUSION

Proof of concept was achieved. The RESTORE intervention should be subject to a definitive trial with some adjustments. Provision of an effective supportive resource would empower cancer survivors to manage CRF after treatment completion.

Pre-Surgery Depression and Confidence to Manage Problems Predict Recovery Trajectories of Health and Wellbeing in the First Two Years following Colorectal Cancer: Results from the CREW Cohort Study

Purpose

This paper identifies predictors of recovery trajectories of quality of life (QoL), health status and personal wellbeing in the two years following colorectal cancer surgery.

Methods

872 adults receiving curative intent surgery during November 2010 to March 2012. Questionnaires at baseline, 3, 9, 15, 24 months post-surgery assessed QoL, health status, wellbeing, confidence to manage illness-related problems (self-efficacy), social support, co-morbidities, socio-demographic, clinical and treatment characteristics. Group-based trajectory analyses identified distinct trajectories and predictors for QoL, health status and wellbeing.

Results

Four recovery trajectories were identified for each outcome. Groups 1 and 2 fared consistently well (scores above/within normal range); 70.5% of participants for QoL, 33.3% health status, 77.6% wellbeing. Group 3 had some problems (24.2% QoL, 59.3% health, 18.2% wellbeing); Group 4 fared consistently poorly (5.3% QoL, 7.4% health, 4.2% wellbeing). Higher pre-surgery depression and lower self-efficacy were significantly associated with poorer trajectories for all three outcomes after adjusting for other important predictors including disease characteristics, stoma, anxiety and social support.

Conclusions

Psychosocial factors including self-efficacy and depression before surgery predict recovery trajectories in QoL, health status and wellbeing following colorectal cancer treatment independent of treatment or disease characteristics. This has significant implications for colorectal cancer management as appropriate support may be improved by early intervention resulting in more positive recovery experiences.

Defining the illness trajectory of metastatic breast cancer

BACKGROUND

With significant developments in the management of metastatic breast cancer, the trajectory of progressive breast cancer is becoming increasingly complex with little understanding of the illness course experienced by women, or their ongoing problems and needs.

AIM

This study set out to systematically explore the illness trajectory of metastatic breast cancer using models from chronic illness as a framework.

DESIGN

Longitudinal mixed methods studies detailing each woman's illness trajectory were developed by triangulating of narrative interviews, medical and nursing documentation and an assessment of functional ability using the Karnofsky Scale. The Corbin and Strauss Chronic Illness Trajectory Framework was used as a theoretical framework for the study.

PARTICIPANTS

Ten women aged between 40 and 78 years, with metastatic breast cancer.

RESULTS

Women's illness trajectories from diagnosis of metastatic disease ranged from 13 months to 5 years and 9 months. Eight of the 10 women died during the study. Chronic illness trajectory phases identified by Corbin and Strauss (pretrajectory, trajectory onset, living with progressive disease, downward phase and dying phase) were experienced by women with metastatic breast cancer. Three typical trajectories of different duration and intensity were identified. Women's lives were dominated by the physical burden of disease and treatment with little evidence of symptom control or support.

CONCLUSIONS

This is the first study to systematically explore the experience of women over time to define the metastatic breast cancer illness trajectory and provides evidence that current care provision is inadequate. Alternative models of care which address women's increasingly complex problems are needed.

Development and testing of a text-mining approach to analyse patients' comments on their experiences of colorectal cancer care

BACKGROUND

Quality of cancer care may greatly impact on patients' health-related quality of life (HRQoL). Free-text responses to patient-reported outcome measures (PROMs) provide rich data but analysis is time and resource-intensive. This study developed and tested a learning-based text-mining approach to facilitate analysis of patients' experiences of care and develop an explanatory model illustrating impact on HRQoL.

METHODS

Respondents to a population-based survey of colorectal cancer survivors provided free-text comments regarding their experience of living with and beyond cancer. An existing coding framework was tested and adapted, which informed learning-based text mining of the data. Machine-learning algorithms were trained to identify comments relating to patients' specific experiences of service quality, which were verified by manual qualitative analysis. Comparisons between coded retrieved comments and a HRQoL measure (EQ5D) were explored.

RESULTS

The survey response rate was 63.3% (21 802/34 467), of which 25.8% (n=5634) participants provided free-text comments. Of retrieved comments on experiences of care (n=1688), over half (n=1045, 62%) described positive care experiences. Most negative experiences concerned a lack of post-treatment care (n=191, 11% of retrieved comments) and insufficient information concerning self-management strategies (n=135, 8%) or treatment side effects (n=160, 9%). Associations existed between HRQoL scores and coded algorithm-retrieved comments. Analysis indicated that the mechanism by which service quality impacted on HRQoL was the extent to which services prevented or alleviated challenges associated with disease and treatment burdens.

CONCLUSIONS

Learning-based text mining techniques were found useful and practical tools to identify specific free-text comments within a large dataset, facilitating resource-efficient qualitative analysis. This method should be considered for future PROM analysis to inform policy and practice. Study findings indicated that perceived care quality directly impacts on HRQoL.

Palliative care patients' perceptions of the work involved in understanding and managing the network of care provision surrounding them

OBJECTIVE

To explore the work carried out for cancer palliative care patients in understanding and dealing with the often large network of care provision surrounding them.

METHOD

Qualitative thematic analysis of interviews with 24 patients (aged 48-85 years) with 15 different types/sites of cancer and palliative care needs.

RESULTS

The main theme of 'patient work-their strategies and project management' is presented. Subthemes included: being organised and keeping records; planning ahead and coordinating care; information gathering; understanding the hierarchy and knowing who the key people are; strategies to remember names and roles; understanding and 'working the system'. Insights are given into the work carried out on patients' behalf by family, although it was unclear who would do this work if no family was available. Some of the challenges faced by patients and families are identified. These included limited information; uncertainty when care is transferred between different teams or locations; deciding who to contact and how; and negotiating through gatekeepers.

CONCLUSIONS

The number and variety of people contributing to the care of a cancer palliative care patient can be difficult for patients and family to comprehend. Work is required by patients or family on their behalf to achieve the level of understanding required to become accomplished at navigating the system and project managing their care organisation, and is probably influenced by role expectations and previous experience. Much of this additional, often hidden, workload for patients and family could probably be reduced with clear, timely information provision by health professionals.

Cancer survivors' self-efficacy to self-manage in the year following primary treatment

PURPOSE

Cancer survivors are increasingly expected to manage the consequences of cancer and its treatment for themselves. There is evidence that self-efficacy is important for successful self-management and that this can be enhanced with support. The purpose of this study was to assess self-efficacy to manage problems in the year following primary treatment.

METHODS

This cross-sectional online survey included cancer survivors who had completed their treatment within the past 12 months. Self-efficacy was assessed and variables expected to be associated with self-efficacy were measured using validated scales including quality of life, well-being, illness perceptions, depression and social support.

RESULTS

One hundred eighty-two respondents (mean age 50; 81% female) completed the survey. They had been treated for a range of cancers; most commonly breast (45%). Self-efficacy scores varied between individuals and according to the illness-related task to be managed. Respondents were least confident in managing fatigue and most confident in accessing information about their cancer. Individuals most likely to report low self-efficacy were women, those experiencing higher levels of pain and/or depression, lower well-being scores, lower socio-economic status, low levels of social support, or a more negative perception of cancer.

CONCLUSIONS

Self-efficacy to self-manage problems faced as a consequence of cancer and its treatment can vary widely in the year following treatment. Fatigue may be particularly difficult to manage.

IMPLICATIONS FOR CANCER SURVIVORS

Variations in self-efficacy highlight the importance of assessing specific problems faced and people's confidence to manage them in order to tailor appropriate self-management support.

Health-related quality of life after colorectal cancer in England: a patient-reported outcomes study of individuals 12 to 36 months after diagnosis

PURPOSE

This population-level study was conducted to define the health-related quality of life (HRQL) of individuals living with and beyond colorectal cancer (CRC) and to identify factors associated with poor health outcomes.

PATIENTS AND METHODS

All individuals diagnosed with CRC in England in 2010 and 2011 who were alive 12 to 36 months after diagnosis were sent a questionnaire. This included questions related to treatment, disease status, other long-term conditions (LTCs), generic HRQL (EuroQol-5D), and cancer-specific outcomes (Functional Assessment of Cancer Therapy and Social Difficulties Inventory items).

RESULTS

The response rate was 63.3% (21,802 of 34,467 patients). One or more generic health problems were reported by 65% of respondents, with 10% of patients reporting problems in all five domains. The reporting of problems was higher than in the general population and was most marked in those age less than 55 years. Certain subgroups reported a higher number of problems, notably those with one or more other LTCs, those with active or recurrent disease, those with a stoma, and those at the extremes of the age range (< 55 and > 85 years). Of respondents without a stoma, 16.3% reported no bowel control. Reversal of a stoma resulted in fewer severe bowel problems but more moderate problems than those who had never had a stoma. A quarter of rectal cancer respondents (25.1%) reported difficulties with sexual matters (compared with 11.2% of colon cancer respondents).

CONCLUSION

This study demonstrates the success of a national patient-reported outcomes survey. The results have the potential to support system-wide improvement in health outcomes through the identification of particular challenges faced by individuals after treatment for CRC.

RESTORE: an exploratory trial of an online intervention to enhance self-efficacy to manage problems associated with cancer-related fatigue following primary cancer treatment: study protocol for a randomized controlled trial

Background

There are over 25 million people worldwide living with or beyond cancer and this number is increasing. Cancer survivors face a range of problems following primary treatment. One of the most frequently reported and distressing symptoms experienced by cancer survivors is fatigue. There is growing support for survivors who are experiencing problems after cancer treatment to engage in supported self-management. To date there is some evidence of effective interventions to manage fatigue in this population; however, to our knowledge there are no online resources that draw on this information to support self-management of fatigue. This paper describes the protocol for an exploratory randomized controlled trial of an online intervention to support self-management of cancer-related fatigue after primary cancer treatment.

Methods/design

This is a parallel-group two-armed (1:1) exploratory randomized controlled trial including 125 cancer survivors experiencing fatigue (scoring ≥4 on a unidimensional 11-point numeric rating scale for fatigue intensity) within five years of primary treatment completion with curative intent. Participants will be recruited from 13 NHS Trusts across the UK and randomized to either the online intervention (RESTORE), or a leaflet comparator (Macmillan Cancer Backup, Coping with Fatigue). The primary outcome is a change in Perceived Self-Efficacy for Fatigue Self-Management (as measured by the Perceived Self-Efficacy for Fatigue Self-Management Instrument). Secondary outcomes include impact on perception and experience of fatigue (measured by the Brief Fatigue Inventory), and quality of life (measured by the Functional Assessment of Cancer Therapy - General and the Personal Wellbeing Index). Outcome measures will be collected at baseline, 6 weeks (completion of intervention), and 3 months. Process evaluation (including telephone interviews with recruiting staff and participants) will determine acceptability of the intervention and trial processes.

Discussion

Data from this trial will be used to refine the intervention and contribute to the design of an effectiveness trial. This intervention will be expanded to address other cancer-related problems important to cancer survivors following primary cancer treatment.

Is a larger specialist nurse workforce in cancer care associated with better patient experience? Cross-sectional study

Objectives:

To assess whether variation in the provision of cancer specialist nurses is associated with the experiences of care for patients undergoing treatment for cancer.

Methods:

This is a cross-sectional study using routinely collected national survey data in 158 acute hospital National Health Service (NHS) Trusts in England. Patients with a primary diagnosis of cancer who attended hospital as inpatients or day cases in the first three months of 2010 responded to a national survey ( n = 67,713, response rate 67%). Patient perceptions of coordination of care, quality of information provision, emotional support and support for symptom management were studied.

Results:

Patients in Trusts that had the fewest patients per specialist nurse were more likely to report that people treating and caring for them worked well together (adjusted odds ratio 1.08, 95% confidence interval 1.01–1.15; p = 0.02) and provided enough emotional support during ambulatory treatment (1.15, 1.01–1.32; p = 0.04), but were no more likely to report being given the right amount of information (0.96, 0.88–1.05; p = 0.38) when compared to patients in Trusts with the most patients per specialist nurse. Breast cancer patients undergoing chemotherapy in the Trusts with fewer patients per specialist nurse were more likely to report good support for the control of side effects from chemotherapy (1.34, 1.02–1.75; p = 0.03).

Conclusions:

Cancer patients’ experience of care coordination and emotional support was better in Trusts with more specialist nurses. The absolute differences were small, and it was unclear whether particular roles or service configurations are associated with better experience.

Patient-reported outcomes of cancer survivors in England 1-5 years after diagnosis: a cross-sectional survey

OBJECTIVES

To determine the feasibility of collecting population-based patient-reported outcome measures (PROMs) in assessing quality of life (QoL) to inform the development of a national PROMs programme for cancer and to begin to describe outcomes in a UK cohort of survivors.

DESIGN

Cross-sectional postal survey of cancer survivors using a population-based sampling approach.

SETTING

English National Health Service.

PARTICIPANTS

4992 breast, colorectal, prostate and non-Hodgkin's lymphoma (NHL) survivors 1-5 years from diagnosis.

PRIMARY AND SECONDARY OUTCOME MEASURES

Implementation issues, response rates, cancer-specific morbidities utilising items including the EQ5D, tumour-specific subscales of the Functional Assessment of Cancer Therapy and Social Difficulties Inventory.

RESULTS

3300 (66%) survivors returned completed questionnaires. The majority aged 85+ years did not respond and the response rates were lower for those from more deprived area. Response rates did not differ by gender, time since diagnosis or cancer type. The presence of one or more long-term conditions was associated with significantly lower QoL scores. Individuals from most deprived areas reported lower QoL scores and poorer outcomes on other measures, as did those self-reporting recurrent disease or uncertainty about disease status. QoL scores were comparable at all time points for all cancers except NHL. QoL scores were lower than those from the general population in Health Survey for England (2008) and General Practice Patient Survey (2012). 47% of patients reported fear of recurrence, while 20% reported moderate or severe difficulties with mobility or usual activities. Bowel and urinary problems were common among colorectal and prostate patients. Poor bowel and bladder control were significantly associated with lower QoL.

CONCLUSIONS

This method of assessing QoL of cancer survivors is feasible and acceptable to most survivors. Routine collection of national population-based PROMs will enable the identification of, and the support for, the specific needs of survivors while allowing for comparison of outcome by service provider.

Qualitative analysis of patients' feedback from a PROMs survey of cancer patients in England

OBJECTIVE

This study examined how free-text comments from cancer survivors could complement formal patient-reported outcome measures (PROMs), as part of the England PROMs survey programme for cancer.

DESIGN

A qualitative content analysis was conducted of responses to a single open-ended free-text question placed at the end of the cross-sectional population-based postal questionnaire.

SETTING

Individuals were identified through three UK Cancer Registries and questionnaires were posted to their home addresses.

PARTICIPANTS

A random sample of individuals (n=4992) diagnosed with breast, colorectal, non-Hodgkins lymphoma or prostate cancer at 1, 2, 3 and 5 years earlier.

RESULTS

3300 participants completed the survey (68% response rate). Of these 1056 (32%) completed the free-text comments box, indicating a high level of commitment to provide written feedback on patient experience. Almost a fifth (19%) related experiences of excellent care during the treatment phase, with only 8% reporting negative experiences. This contrasted with experiences of care after primary cancer treatment where the majority were negative. Factors impacting negatively upon patient-reported outcomes included the emotional impact of cancer; poor experiences of treatment and care; comorbidities, treatment side effects, social difficulties and inadequate preparation for a wide range of sometimes long-lasting on-going physical and psychological problems. Mediating factors assisting recovery incorporated both professional-led factors, such as quality of preparation for anticipated problems and aftercare services, and participant-led factors, such as learning from other cancer survivors and self-learning through trial and error. The support of friends and family was also a factor in participants' outcomes.

CONCLUSIONS

This analysis of free-text comments complements quantitative analysis of PROMs measure's by illuminating relationships between factors that impact on quality of life (QoL) and indicate why cancer patients may experience significantly worse QoL than the general population. The data suggest more systematic preparation and aftercare for individuals to self-manage post-treatment problems might improve QoL outcomes among cancer survivors.

Eliciting symptoms interpreted as normal by patients with early-stage lung cancer: could GP elicitation of normalised symptoms reduce delay in diagnosis? Cross-sectional interview study

OBJECTIVES

To investigate why symptoms indicative of early-stage lung cancer (LC) were not presented to general practitioners (GPs) and how early symptoms might be better elicited within primary care.

DESIGN, SETTING AND PARTICIPANTS

A qualitative cross-sectional interview study about symptoms and help-seeking in 20 patients from three south England counties, awaiting resection of LC (suspected or histologically confirmed). Analysis drew on principles of discourse analysis and constant comparison to identify processes involved in interpretation and communication about symptoms, and explain non-presentation.

RESULTS

Most participants experienced health changes possibly indicative of LC which had not been presented during GP consultations. Symptoms that were episodic, or potentially caused by ageing or lifestyle, were frequently not presented to GPs. In interviews, open questions about health changes/symptoms in general did not elicit these symptoms; they only emerged in response to closed questions detailing specific changes in health. Questions using disease-related labels, for example, pain or breathlessness, were less likely to elicit symptoms than questions that used non-disease terminology, such as aches, discomfort or 'getting out of breath'. Most participants described themselves as feeling well and were reluctant to associate potentially explained, non-specific or episodic symptoms with LC, even after diagnosis.

CONCLUSIONS

Patients with early LC are unlikely to present symptoms possibly indicative of LC that they associate with normal processes, when attending primary care before diagnosis. Faced with patients at high LC risk, GPs will need to actively elicit potential LC symptoms not presented by the patient. Closed questions using non-disease terminology might better elicit normalised symptoms.

A cohort study of the recovery of health and wellbeing following colorectal cancer (CREW study): protocol paper

Background

The number of people surviving colorectal cancer has doubled in recent years. While much of the literature suggests that most people return to near pre-diagnosis status following surgery for colorectal cancer, this literature has largely focused on physical side effects. Longitudinal studies in colorectal cancer have either been small scale or taken a narrow focus on recovery after surgery. There is a need for a comprehensive, long-term study exploring all aspects of health and wellbeing in colorectal cancer patients. The aim of this study is to establish the natural history of health and wellbeing in people who have been treated for colorectal cancer. People have different dispositions, supports and resources, likely resulting in individual differences in restoration of health and wellbeing. The protocol described in this paper is of a study which will identify who is most at risk of problems, assess how quickly people return to a state of subjective health and wellbeing, and will measure factors which influence the course of recovery.

Methods/design

This is a prospective, longitudinal cohort study following 1000 people with colorectal cancer over a period of two years, recruiting from 30 NHS cancer treatment centres across the UK. Questionnaires will be administered prior to surgery, and 3, 9, 15 and 24 months after surgery, with the potential to return to this cohort to explore on-going issues related to recovery after cancer.

Discussion

Outcomes will help inform health care providers about what helps or hinders rapid and effective recovery from cancer, and identify areas for intervention development to aid this process. Once established the cohort can be followed up for longer periods and be approached to participate in related projects as appropriate and subject to funding.

Quality of life and experience of care in women with metastatic breast cancer: a cross-sectional survey

CONTEXT

Despite developments in the medical management of metastatic breast cancer, little is known about the quality of life (QoL) and experience of care in women with it.

OBJECTIVES

To explore QoL, experience of care, and support needs of women living with metastatic breast cancer in the U.K.

METHODS

Questionnaire-based, cross-sectional study, undertaken in two U.K. cancer centers and online via the Breast Cancer Care website, assessing QoL and experience of care in 235 women with metastatic breast cancer.

RESULTS

QoL was assessed using the Functional Assessment of Cancer Therapy--Breast QoL measure. Overall, QoL was low (mean 89.0, standard deviation 21.8) for total score. Low scores were seen uniformly in physical, social, emotional, and functional well-being domains. Symptom burden was a significant problem, with over one-third of women (34%) reporting high levels of pain and other uncontrolled symptoms. In multiple regression analysis, social well-being was significantly better for older women (P<0.001) but was lower in those with bone metastases only (P=0.002). Functional well-being was significantly higher in women without children (P=0.004). Satisfaction with experience of care was low and appeared to be predominantly in the hospital setting, with little evidence of involvement of general practitioners and palliative care services.

CONCLUSION

Despite improvements in treatment and survival of women with metastatic breast cancer, this group reports high symptom burden and dissatisfaction with elements of their care, indicating that alternative models of service delivery should be explored.
