Utilization of the Medical Research Council evaluation framework in the development of technology for symptom management: the ASyMS-YG Study

BACKGROUND

Technology is becoming an important medium for supporting patients in health care. However, successful application depends on user acceptability. The Advanced Symptom Management System (ASyMS) involves patients reporting cancer chemotherapy-related symptoms using mobile phone technology.

OBJECTIVE

The aim of this article was to report a study of how young people were involved in the development of ASyMS using the Medical Research Council framework for evaluating complex interventions.

METHODS

A convenience sample of young people aged 13 to 18 years undergoing cancer chemotherapy were recruited from 2 principal cancer treatment centers in London.

RESULTS

In phase 1, young people selected 5 symptoms from an adapted version of the Memorial Symptom Assessment Scale that were most important to them. In phase 2, young people completed the ASyMS-YG PDA (personal digital assistant) questionnaire daily on days 1 to 14 of a cycle of chemotherapy and pre/post-use questionnaires. In phase 1, 5 young people chose diarrhea, nausea, vomiting, constipation, and weight loss as the most important symptoms. In phase 2, 25 young people reported positively to using PDA technology, found ASyMS-YG simple and easy to complete, and liked that they were monitored at home. In addition to the 5 core symptoms, the ASyMS-YG reports showed the number (n = 37) of other symptoms young people experienced.

CONCLUSIONS

This early development work indicates the acceptability of ASyMS-YG and has informed an exploratory trial (phase 3) and randomized controlled trial (stage 4).

IMPLICATIONS FOR PRACTICE

This study reaffirms the importance of promoting communication between young people and health professionals.

Challenging symptom profiles of life-limiting conditions in children: a survey of care professionals and families

This paper reports on data from the initial phase of a UK-wide study exploring life-limiting conditions (LLCs) in children where, because of their rarity, little is understood regarding the significant symptom challenges of families and care professionals who support them. In this initial phase, care professionals (n=43) and families (n=16) completed a survey to identify which rare LLCs present symptom challenges and which individual symptoms prove difficult to manage. Findings led to the prioritization of mucopolysaccharidoses, Batten Disease and leukodystrophy. Care professionals' rationales for selecting these conditions included the presence of symptoms that are very difficult to manage, a requirement for additional clinical evidence to support symptom management, and the progressive nature of these diseases where symptoms frequently change and are difficult to predict. Families identified symptoms such as behavioural difficulties, visual impairments and communication impairments as those being most difficult to manage and having most impact on quality of life for children and families.

Children's understanding of cancer and views on health-related behaviour: a 'draw and write' study

BACKGROUND

Few studies have explored young children's understanding of cancer and health-related behaviours yet this is essential to develop health promotion initiatives that build on young children's current knowledge levels and awareness.

METHOD

An exploratory descriptive design using the 'draw and write' technique was used to investigate children's views of cancer and health behaviours. The sample included 195 children aged eight to 11 years from five schools in deprived, affluent and rural locations in Scotland.

RESULTS

When asked about cancer children demonstrated a good level of awareness by responding with text and drawings about the what they understood cancer to be; types of cancer; causes of cancer; what happens to people who have cancer; their personal experience of cancer and the emotions they associated with cancer. Older children, and children attending affluent schools, have more defined ideas about the causes of cancer and awareness of broader issues such as the risk of passive smoking or the potential impact on the family. Factors such as alcohol and illegal drugs were only reported by children attending schools in deprived locations. Children demonstrated considerable knowledge about healthy and unhealthy lifestyle behaviours; however, it is not clear whether this knowledge translates into their behaviours or the choices offered within their home environment.

CONCLUSIONS

Children view cancer in a negative way from an early age, even without personal experience. There is a need to demystify cancer in terms of its causes, how to recognize it, how it is treated and to publicize improved survival rates. There is a need for targeted and developmentally appropriate approaches to be taken to health education in schools, with an awareness of the influence of the media on children's information. Strategies should take into consideration the socio-economic and cultural contexts of children's lives which influence their choices and behaviours.

Working in collaboration with young people and health professionals. A staged approach to the implementation of a randomised controlled trial

ASyMS© is an Advanced Symptom Management System utilising mobile phone technology to monitor chemotherapy-related symptoms and promote self-care. It was first developed with an adult cancer population and is now being evaluated with young people through an iterative development process. ASyMS© involves patients recording and sending symptom reports to the hospital and receiving tailored self-care advice. Health professionals are alerted when severe symptoms are reported. Three phases of the ASyMS©-YG (young people) study are complete. Phase 1 involved young people identifying the symptoms to be assessed. Phase 2 involved young people testing the symptom report system, and ascertaining young people’s, parents’ and professionals’ perceptions of ASyMS©-YG. This paper reports on Phase 3, in which the system was developed further in preparation for a randomised controlled trial (RCT). Health professionals devised an alert system based on risk modelling side-effect severity, and young people and professionals developed self-care advice. A pilot study was conducted to test the alert system and study design in readiness for a definitive RCT. The contribution young people and professionals have made to this project is invaluable in evaluating the practical effectiveness of ASyMS©-YG and ensuring the intervention is acceptable and works in everyday practice.

Antiemetic medication for prevention and treatment of chemotherapy induced nausea and vomiting in childhood

BACKGROUND

Nausea and vomiting are still a problem for children undergoing treatment for malignancies despite new antiemetic therapies. Optimising antiemetic regimens could improve quality of life by reducing nausea, vomiting and associated clinical problems.

OBJECTIVES

To assess the effectiveness and adverse events of pharmacological interventions in controlling anticipatory, acute and delayed nausea and vomiting in children and young people (aged < 18 years) about to receive/receiving chemotherapy.

SEARCH STRATEGY

Searches included CENTRAL, MEDLINE, EMBASE and LILACS, trial registries from their earliest records to February 2008, and ASCO, MASCC and SIOP conference proceedings from 2001 to 2007. We examined references of systematic reviews and contacted trialists for information on further studies.

SELECTION CRITERIA

Two authors independently screened abstracts to identify randomised controlled trials (RCTs) that compared a pharmacological antiemetic, cannabinoid or benzodiazepine with placebo or any alternative active intervention in children and young people (< 18 years) with a diagnosis of cancer who were to receive chemotherapy.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted outcome and quality data from each RCT. When appropriate, we undertook meta-analysis.

MAIN RESULTS

We included 28 studies which examined a range of different antiemetics, used different doses and comparators, and reported a variety of outcomes. The quality and quantity of included studies limited the exploration of heterogeneity to narrative approaches only.The majority of quantitative data related to the complete control of acute vomiting (22 studies). Adverse events were reported in 24 studies and nausea outcomes in 10 studies.The addition of dexamethasone to 5-HT(3) antagonists was assessed in two studies for complete control of vomiting (pooled relative risk (RR) 2.03; 95% CI 1.35 to 3.04). Three studies compared granisetron 20 mcg/kg with 40 mcg/kg for complete control of vomiting (pooled RR 0.93; 95% CI 0.80 to 1.07). No other pooled analyses were possible.Narrative synthesis suggests 5-HT(3) antagonists are more effective than older antiemetic agents even when combined with a steroid. Cannabinoids are probably effective but produce frequent side effects.

AUTHORS' CONCLUSIONS

Our overall knowledge of the most effective antiemetics to prevent chemotherapy-induced nausea and vomiting in childhood is incomplete. Future research should be undertaken in consultation with children, young people and families that have experienced chemotherapy and should make use of validated, age-appropriate measures. This review suggests that 5-HT(3) antagonists with dexamethasone added are effective in patients who are to receive highly emetogenic chemotherapy although the risk-benefit profile of additional steroid remains uncertain.

The stories of young people living with a liver transplant

Adolescence is a difficult time for those with chronic illness because of the constraints of the illness on developmental tasks. Little is known about the impact liver transplantation has during adolescence. In this study we aimed to explore, in their own words, young people's lived experience of life after transplantation. We used semistructured interviews to collect narrative data, and used a purposive sample of 14 young people in early, middle, and late adolescence, transplanted for a range of chronic, acute, and metabolic liver diseases. We analyzed the transcripts using a framework in which analysis progresses through a five-stage process of matrices. Six main themes emerged, related to relationships, affect on schooling, tiredness and fatigue, acceptance of the burden of medication, communication with health professionals, and view of the future. These findings add new insight into the transplantation experience, which might lead to improvements in care and help direct further research in this important aspect of clinical care.

Audit to monitor the uptake of national mouth care guidelines for children and young people being treated for cancer

PURPOSE

The aim of this study is to review current oral care practices in children being treated for cancer against audit criteria derived from national guidelines, and to compare findings with data from a baseline survey carried out in 2002 prior to implementation of the national guidelines.

METHODS

A telephone survey was carried out of all 21 haematology-oncology (HO) centres and seven bone marrow transplant (BMT) units within the UK Children's Cancer Study Group focusing on key audit themes of: availability of evidence-based guidelines, oral and dental care prior to and during cancer treatment, oral assessment, prevention and treatment of oral complications.

RESULTS

The national guidelines were used in 19/25 (76%) settings that employed written guidelines. There was little variation in advice given to patients/parents on basic oral hygiene, and this advice was commensurate with guideline recommendations. Inconsistencies in oral care assessment, reported at baseline, remained commonplace across the majority of settings. In only 10/21 HO centres, it was usual practice for children to undergo dental assessment prior to commencing cancer treatment, indicating no improvement since baseline survey. Few therapies outside of the guideline recommendations were being used. The routine use of preventive nystatin, not recommended in the guideline, had significantly decreased from baseline (by 40%).

CONCLUSIONS

Uptake of national guidelines by HO/BMT settings was good however certain oral care practices fell short of the guideline recommendations. Routine dental checks need to be embedded in practice. Further consideration is needed as to how oral assessment might be used more effectively in informing treatment.

Measuring quality of life in children and young people after transplantation: methodological considerations

The measurement of QoL has become an important area for research in paediatric transplantation over the past 15 yr. While much of this work remains descriptive and exploratory, advances in treatment and the trend towards outcomes being patient centred and not just survival based suggest the measurement of QoL will be of far more importance and relevance in the future. In this discussion article, we will outline some of the issues that need to be considered when embarking on a QoL study. The aim of our account is not to be prescriptive, rather to present researchers and clinicians with questions and possible solutions to help increase the scientific robustness of future studies. We have included summary tables of instruments that are currently available as a resource for those wanting to evaluate QoL in paediatric transplantation.

Waved aCGH: to smooth or not to smooth

Array-based comparative genomic hybridization (aCGH) is a powerful tool to detect genomic imbalances in the human genome. The analysis of aCGH data sets has revealed the existence of a widespread technical artifact termed as ‘waves’, characterized by an undulating data profile along the chromosome. Here, we describe the development of a novel noise-reduction algorithm, waves aCGH correction algorithm (WACA), based on GC content and fragment size correction. WACA efficiently removes the wave artifact, thereby greatly improving the accuracy of aCGH data analysis. We describe the application of WACA to both real and simulated aCGH data sets, and demonstrate that our algorithm, by systematically correcting for all known sources of bias, is a significant improvement on existing aCGH noise reduction algorithms. WACA and associated files are freely available as Supplementary Data.

Contemporary issues relating to assessment of pre-registration nursing students in practice

Clinical placements are an essential part of pre-registration nurse education. Mentors have a vital role in providing constructive feedback and assessing the student throughout their placement. There have been reports of failing to fail students in practice, however, little evidence has been provided to support this. This paper provides an insight into apparent mismatches between mentor feedback given to students in their practice assessment documents and feedback given to university and Trust staff anonymously. Our findings appear to illustrate issues of inconsistency and a lack of ability to give accurate feedback on professional values and behaviours. This is in contrast to the feedback on clinical skills - in which the mentors appeared to be in agreement, with the written comments being supported by congruent scores in the relevant competencies.

Study of the factors affecting health-related quality of life in adolescents after liver transplantation

The aim of the study was to identify factors affecting health-related quality of life (HRQL) in adolescents after liver transplantation. HRQL was measured using the CHQ-CF87 in 55 adolescents, aged 12-18 years. Factors associated with HRQL included allograft morbidity, psychological and family-related variables measured through standardized questionnaires. The domains of the CHQ-CF87 were reduced using factor analysis to give physical, psychological and social domains. Impacting factors were identified through stepwise, multiple regression analysis. Adolescents had significantly lower HRQL in every domain except for role/social-behavior and family cohesion compared to the general population. Adolescents experienced median 18 (range 4-31) symptoms related to immunosuppression, 40(75%) had one or more chronic illnesses related to immunosuppression and 12(22%) had a history of emotional difficulties. Self-esteem and emotional health were similar to the general population but behavior and aspects of family function were lower. Following regression analysis, the factors associated with HRQL were: age at transplant, secondary chronic illness, symptom distress, headaches, history of emotional difficulties, self-esteem and family conflict. These explained 57% of the variance in physical function, 61% of psychological function and 39% of social function. HRQL is significantly reduced in adolescents after transplantation, which could be related to immunosuppression and psychosocial factors.

The experience of living with a chronic illness during adolescence: a critical review of the literature

AIMS

To identify and critique literature on the adolescent lived experience of chronic illness; describe the lived experience; and to make recommendations for clinical practice.

BACKGROUND

Young people with chronic illness have the same developmental issues as those who are healthy. However, development can be disrupted by treatment and repeated hospitalisation. While the physical consequences of chronic illness on development have been established, the subjective personal experience is less known.

DESIGN

Literature review.

METHODS

Electronic databases and hand searches were made of the literature published between January 1990-September 2007. Literature was eligible for inclusion if it involved adolescents between 10-19 years, and published in English and used qualitative methods of data collection. Methodological quality was assessed using the criteria described by Cesario et al. [Journal of Obstetrics, Gynaecology and Neonatal Nursing 31 (2002) 31].

CONCLUSIONS

Twenty studies were identified involving young people with a wide variety of chronic illnesses. The study quality was variable, however, generally the majority was assessed as being good or fair. Seven common themes were found between the identified studies: developing and maintaining friendships; being normal/getting on with life; the importance of family; attitude to treatment; experiences of school; relationship with the healthcare professionals; and the future.

RELEVANCE TO PRACTICE

As there was commonality in themes between studies strategies to lessen the burden of chronic illness during adolescence do not necessarily need to be disease specific. Nurses need to focus on treating the young person rather than their illness.
