The utility of a portable muscle ultrasound in the assessment of muscle alterations in children with acute lymphoblastic leukaemia.

BACKGROUND: During treatment for acute lymphoblastic leukaemia (ALL), children are prone to musculoskeletal deterioration. However, non-invasive tools to measure muscle mass and intramuscular alterations are limited. In this study we explored the feasibility of muscle ultrasound in children with ALL. Additionally, we analysed whether automated ultrasound outcomes of muscle size and intramuscular fat infiltration (IMAT) were associated with appendicular skeletal muscle mass (ASMM), muscle strength and physical performance. METHODS: Children with ALL, aged 3-18 years were included during maintenance therapy. Bilateral images of the rectus femoris muscle were captured using a portable linear array transducer connected to a tablet. Subsequently, an automated image annotation software (MuscleSound) was used to estimate cross-sectional area, muscle thickness and IMAT. Feasibility was assessed using acceptance (percentage of children approached who were enrolled), practicality (percentage of children that completed the ultrasound measurement after enrolment) and implementation (percentage of children that had sufficient imaging to be processed and analysed by the software). Assessments of ASMM by bioimpedance analysis, muscle strength using handheld dynamometry and timed physical performance tests were administered at the same visit. Multivariable linear models were estimated to study the associations between muscle ultrasound outcomes and ASMM, strength and physical performance, adjusted for sex, age, body mass index and ALL treatment week. RESULTS: Muscle ultrasound was performed in 60 out of 73 invited patients (76.9%), of which 37 were boys (61.7%), and median age was 6.1 years (range: 3-18.8 years). The acceptance was 98.7%, practicality 77.9% and implementation was 100%. Patients who refused the examination (n = 13) were younger (median: 3.6, range: 3-11.2 years) compared with the 60 examined children (P = 0.0009). In multivariable models, cross-sectional area was associated with ASMM (ß = 0.49 Z-score, 95% confidence interval [CI]:0.3,2.4), knee-extension strength (ß = 16.9 Newton [N], 95% CI: 4.8, 28.9), walking performance (ß = -0.46 s, 95% CI: -0.75, -0.18) and rising from the floor (ß = -1.07 s, 95% CI: -1.71, -0.42). Muscle thickness was associated with ASMM (ß = 0.14 Z-score, 95% CI: 0.04, 0.24), knee-extension strength (ß = 4.73 N, 95% CI: 0.99, 8.47), walking performance (ß = -0.13 s, 95% CI: -0.22, -0.04) and rising from the floor (ß = -0.28 s, 95% CI: -0.48, -0.08). IMAT was associated with knee-extension strength (ß = -6.84 N, 95% CI: -12.26, -1.41), walking performance (ß = 0.2 s, 95% CI: 0.08, 0.32) and rising from the floor (ß = 0.54 s, 95% CI: 0.27, 0.8). None of the muscle ultrasound outcomes was associated with handgrip strength. CONCLUSIONS: Portable muscle ultrasound appears a feasible and useful tool to measure muscle size and intramuscular alterations in children with ALL. Validation studies using magnetic resonance imaging (gold standard) are necessary to confirm accuracy in paediatric populations.

Internet and smartphone-based ecological momentary assessment and personalized advice (PROfeel) in adolescents with chronic conditions: A feasibility study.

OBJECTIVE: Growing up with a chronic disease comes with challenges, such as coping with fatigue. Many adolescents are severely fatigued, though its associated factors exhibit considerable interpersonal and longitudinal variation. We assessed whether PROfeel, a combination of a smartphone-based ecological momentary assessment (EMA) method using the internet, followed by a face-to-face dialogue and personalized advice for improvement of symptoms or tailor treatment based on a dynamic network analysis report, was feasible and useful. STUDY DESIGN: Feasibility study in fatigued outpatient adolescents 12-18 years of age with cystic fibrosis, autoimmune disease, post-cancer treatment, or with medically unexplained fatigue. Participants were assessed at baseline to personalize EMA questions. EMA was conducted via smartphone notifications five times per day for approximately six weeks. Hereby, data was collected via the internet. The EMA results were translated into a personalized report, discussed with the participant, and subsequently translated into a personalized advice. Afterwards, semi-structured interviews on feasibility and usefulness were held. RESULTS: Fifty-seven adolescents were assessed (mean age 16.2 y ± 1.6, 16% male). Adolescents deemed the smartphone-based EMA feasible, with the app being used for an average of 49 days. Forty-two percent of the notifications were answered and 85% of the participants would recommend the app to other adolescents. The personalized report was deemed useful and comprehensible and 95% recognized themselves in the personalized report, with 64% rating improved insight in their symptoms and subsequent steps towards an approach to reduce one's fatigue as good or very good. CONCLUSIONS: PROfeel was found to be highly feasible and useful for fatigued adolescents with a chronic condition. This innovative method has clinical relevance through bringing a patient's daily life into the clinical conversation.

A retrospective assessment of the KLIK PROM portal implementation using the Consolidated Framework for Implementation Research (CFIR).

PURPOSE: The KLIK Patient-Reported Outcome Measure (PROM) portal is an evidence-based intervention implemented in clinical practice in > 25 Dutch hospitals for patients (children and adults) who regularly visit the outpatient clinic. Implementation science frameworks can be used to understand why implementation succeeded or failed, to structure barriers and enablers, and to develop implementation strategies to overcome barriers. This paper aimed to (A) retrospectively describe determinants of successful KLIK PROM implementation using the Consolidated Framework for Implementation Research (CFIR), and (B) identify current barriers and match implementation strategies. METHODS: (A) The KLIK implementation process was described retrospectively based on literature and experience, using the 39 CFIR constructs organized in five general domains: intervention characteristics, outer setting, inner setting, characteristics of individuals, and implementation process. (B) The CFIR-Expert Recommendations for Implementing Change (ERIC) Implementation Strategy Matching tool identified current barriers in the KLIK implementation and matched implementation strategies that addressed the identified barriers. RESULTS: (A) The most prominent determinants of successful KLIK PROM implementation lie in the following CFIR domains: intervention characteristics (e.g., easy to use), characteristics of individuals (e.g., motivation), and process of implementation (e.g., support). (B) 13 CFIR constructs were identified as current barriers for implementing the KLIK PROM portal. The highest overall advised ERIC strategy for the specific KLIK barriers was to identify and prepare champions. CONCLUSION: Using an implementation science framework, e.g., CFIR, is recommended for groups starting to use PROMs in clinical care as it offers a structured approach and provides insight into possible enablers and barriers.

Matching Psychosocial Support Needs of Parents of a Child with a Chronic Illness to a Feasible Intervention.

OBJECTIVES: Parents of children with a chronic illness (CI) are at risk for psychosocial problems. The aim of this study was to refine an existing face-to-face intervention into an online psychosocial group intervention for parents by (1) exploring which themes are important, (2) determine what type of intervention parents would like and (3) assess parents' practical preferences. METHODS: Parents of children with a CI (0-18 years) were invited to complete an online questionnaire. To acquire more in-depth information, focus groups and telephone interviews were conducted. Descriptive statistics were used. RESULTS: 272 parents (mean age = 43.1 years, 85% female) participated. Three focus groups (15 parents) and seven telephone interviews were conducted. Most important themes were: the CI of the child, family functioning, taking care of yourself, relationships with others and practical support. Parents preferred a group with parents of children in the same age category. At first, parents preferred face-to-face contact. After an explanation and demonstration of an online intervention, parents became more positive about online support, mostly because they could participate from home. CONCLUSIONS FOR PRACTICE: Parents have a need for psychosocial support focusing on different themes. Professionals should explain and demonstrate an online intervention to parents. Based on these results, Op Koers Online for parents was developed. An RCT to assess feasibility and effectiveness of the intervention is currently running.

First experience with electronic feedback of the Psychosocial Assessment Tool in pediatric cancer care.

PURPOSE: The Psychosocial Assessment Tool (PAT) is a brief family screener, identifying families at universal or elevated risk for psychosocial problems. This study aimed to determine the feasibility and usability of the electronic PAT (ePAT) in pediatric cancer care. METHODS: Eighty-six parents of newly diagnosed children with cancer (0-18 years) agreed to participate and registered at the website www.hetklikt.nu (58%). Seventy-five families completed the ePAT at approximately 1 month post-diagnosis. Answers were transformed into an electronic PROfile (PAT ePROfile) and fed back to the psychosocial team. Team members completed a semi-structured evaluation questionnaire. Feasibility was measured as the percentage of website registrations, completed ePATs, and PAT ePROfiles reviewed or discussed by the team. Usability included perceived match of the PAT ePROfile with the team's own risk estimation, perceived added value, and perceived actions undertaken as a result of the PAT ePROfile. RESULTS: Feasibility was 70% for website registration, 87% for completed ePATs, 85% for PAT ePROfile reviewing, and 67% for ePROfile discussion. Team members reported that the PAT ePROfile matched with their own risk estimation (M = 7.92, SD = 1.88) and did not provide additional information (M = 2.18, SD = 2.30). According to the team, actions were undertaken for 25% of the families as a result of the PAT ePROfile. More actions were undertaken for families with elevated risk scores compared to universal risk scores (p = .007). CONCLUSIONS: Implementation of the ePAT seems generally feasible, but it is not always clear how this screener adds to current clinical practice. Strategies should be developed together with team members to improve quick exchange of ePAT results and allocate care according to the needs of the families.

Healthcare Professionals' Preferences and Perceived Barriers for Routine Assessment of Patient-Reported Outcomes in Pediatric Oncology Practice: Moving Toward International Processes of Change.

BACKGROUND: Using patient-reported outcomes (PROs) in clinical practice has been shown to enhance detection of health-related quality of life problems and satisfaction with care in children with cancer. This study seeks to identify which PRO information healthcare professionals (HCPs) find useful and what the perceived barriers for routinely assessing PROs are. PROCEDURE: A total of 352 pediatric HCPs (43% male) from 52 countries completed a semistructured online 28-item questionnaire. Descriptive statistics (percentages) were used to identify highly important PRO information and perceived barriers. HCPs' perceived barriers were compared according to gender, years of work experience, and country using a Fishers exact test. RESULTS: The five highest ranked PRO topics relevant in routine assessment by HCPs were as follows: pain (98%), feeling sad or depressed (96%), overall physical symptoms (95%), problems with therapy adherence (94%), and overall emotional issues (93%). Five lowest ranked topics were as follows: difficulties praying (50%), other spiritual concerns (55, 56, and 60%), and feeling bored (60%). Barriers for assessing PROs included: time (58%), insufficient staff (49%), logistics (32%), and financial resources (26%). Providers from developing countries more often reported barriers concerning insufficient staff, logistics, and financial resources. CONCLUSIONS: HCPs strongly value the use of physical and psychosocial PROs within pediatric oncology practice, but mainly perceive organizational barriers for routine assessment. To successfully integrate PROs, efforts should be made to address HCP-perceived barriers, such that patient-reported problems can be detected and timely referrals made.

Impact of Renal Replacement Therapy in Childhood on Long-Term Socioprofessional Outcomes: A 30-year Follow-Up Study.

OBJECTIVE: To evaluate socioprofessional outcomes after 30 years of renal replacement therapy (RRT) and explore predictors of these outcomes. STUDY DESIGN: The cohort comprised all Dutch patients, born before 1979, who started RRT at age <15 years in 1972-1992. Outcomes including family life, educational attainment, and professional life were obtained in 2000 and 2010 in 80 out of 152 survivors. Participants also completed the Course of Life Questionnaire in 2000, which retrospectively assessed the achievement of developmental milestones while growing up. Socioprofessional outcomes in 2010 were compared with the age-matched general population and with outcomes obtained in 2000. Logistic regression analysis was performed to identify determinants of socioprofessional outcomes. RESULTS: Mean age and time on RRT in 2010 were 40.6 years (range 32.1-52.4) and 28.9 years (range 18.1-39.7), respectively. Patients were less likely to be employed (62.5% vs 81.0%) and have children (28.8% vs 64.8%) compared with the age-matched general population. Comorbidities, dialysis, short stature, and fewer milestones on autonomy were associated with adverse outcomes. Compared with 2000, in 2010 more patients lived with a partner (68.8% vs 43.0%), and more patients had completed a high level educational degree (22.5% vs 13.9%). However, more patients were unable to work on medical grounds in 2010 (36.3% vs 16.3%). CONCLUSIONS: Survivors of pediatric end-stage renal disease may gain social autonomy and optimal educational attainment at an older age compared with their general population counterparts. Awareness among health care professionals of the potential of these children and tailored psychosocial interventions might improve socioprofessional development.

Screening for Psychosocial Risk in Dutch Families of a Child With Cancer: Reliability, Validity, and Usability of the Psychosocial Assessment Tool.

OBJECTIVE: The Psychosocial Assessment Tool (PAT) was developed to screen for psychosocial risk in families of a child diagnosed with cancer. The current study is the first describing the cross-cultural adaptation, reliability, validity, and usability of the PAT in an European country (Dutch translation). METHODS: A total of 117 families (response rate 59%) of newly diagnosed children with cancer completed the PAT2.0 and validation measures. RESULTS: Acceptable reliability was obtained for the PAT total score (α = .72) and majority of subscales (0.50-0.82). Two subscales showed inadequate internal consistency (Social Support α = .19; Family Beliefs α = .20). Validity and usability were adequate. Of the families, 66% scored low (Universal), 29% medium (Targeted), and 5% high (Clinical) risk. CONCLUSIONS: This study confirms the cross-cultural applicability, reliability, and validity of the PAT total score. Reliability left room for improvement on subscale level. Future research should indicate whether the PAT can be used to provide cost-effective care.

Dutch-Flemish translation of nine pediatric item banks from the Patient-Reported Outcomes Measurement Information System (PROMIS)®.

PURPOSE: The Patient-Reported Outcomes Measurement Information System (PROMIS(®)) is a new, state-of-the-art assessment system for measuring patient-reported health and well-being of adults and children. It has the potential to be more valid, reliable, and responsive than existing PROMs. The items banks are designed to be self-reported and completed by children aged 8-18 years. The PROMIS items can be administered in short forms or through computerized adaptive testing. This paper describes the translation and cultural adaption of nine PROMIS item banks (151 items) for children in Dutch-Flemish. METHODS: The translation was performed by FACITtrans using standardized PROMIS methodology and approved by the PROMIS Statistical Center. The translation included four forward translations, two back-translations, three independent reviews (at least two Dutch, one Flemish), and pretesting in 24 children from the Netherlands and Flanders. RESULTS: For some items, it was necessary to have separate translations for Dutch and Flemish: physical function-mobility (three items), anger (one item), pain interference (two items), and asthma impact (one item). Challenges faced in the translation process included scarcity or overabundance of possible translations, unclear item descriptions, constructs broader/smaller in the target language, difficulties in rank ordering items, differences in unit of measurement, irrelevant items, or differences in performance of activities. By addressing these challenges, acceptable translations were obtained for all items. CONCLUSION: The Dutch-Flemish PROMIS items are linguistically equivalent to the original USA version. Short forms are now available for use, and entire item banks are ready for cross-cultural validation in the Netherlands and Flanders.

Psychosocial Assessment as a Standard of Care in Pediatric Cancer.

This paper presents the evidence for a standard of care for psychosocial assessment in pediatric cancer. An interdisciplinary group of investigators utilized EBSCO, PubMed, PsycINFO, Ovid, and Google Scholar search databases, focusing on five areas: youth/family psychosocial adjustment, family resources, family/social support, previous history/premorbid functioning, and family structure/function. Descriptive quantitative studies, systematic reviews, and meta-analyses (n = 149) were reviewed and evaluated using grading of recommendations, assessment development, and evaluation (GRADE) criteria. There is high quality evidence to support a strong recommendation for multifaceted, systematic assessments of psychosocial health care needs of youth with cancer and their families as a standard of care in pediatric oncology.

Innovations in e-health.

The theme of ISOQOL's 19th Annual Conference in Budapest, Hungary, was The Journey of Quality of Life Research: A Path Towards Personalized Medicine. Innovations in e-health was one of four plenary panels. E-health is changing the landscape of clinical practice and health care, but the best way to leverage the many promised benefits of emerging e-health technologies is still not clear. The Innovations in e-health panel presented emerging changes in technologies and applications that will facilitate clinical decision making, improve quality and efficiency of care, engage individuals in clinical decision making, and empower them to adopt healthy behaviors. The purpose of this paper was to present emerging trends in e-health and considerations for successful adoption of new technologies, and an overview of each of the presentations in the e-health plenary. The presentations included a personal perspective on the use of technology for self-monitoring in Parkinson's disease, an overview of online social networks and emerging technologies, and the collection of patient-reported outcomes through web-based systems in clinical practice. The common thread across all the talks was the application of e-health tools to empower individuals with chronic disease to be actively engaged in the management of their health. Considerations regarding data ownership and privacy, universal access to e-health, interactivity between different types of e-health technologies, and tailoring applications to individual needs were explored.

Monitoring health-related quality of life in paediatric practice: development of an innovative web-based application.

BACKGROUND: Health Related Quality of Life (HRQOL) questionnaires are increasingly used in clinical practice. These Patient Reported Outcomes (PROs) are provided to the paediatrician to facilitate communication with patients during a consultation. The aim of the current article is to describe the development and introduction of a new web-based application for the use of PROs in daily paediatric clinical practice. METHODS: Currently, the use of PROs in daily clinical practice is very time consuming and often has logistical problems. The use of a web-based programme can overcome these problems and contributes to an improved use of PROs in clinical practice. We therefore developed an easily accessible website (KLIK) for outpatient treatment and a training programme for paediatricians to maximize the effectiveness and the practical use of PROs (KLIK PROfile). RESULTS: The KLIK study was launched in August 2008 to evaluate the use of the KLIK PROfile in daily clinical practice. The KLIK study evaluates whether feedback from HRQOL data could influence patient satisfaction with the consultation, the advice given, the type of referrals and topics discussed. In this multicentre study, a control group (without the use of the KLIK PROfile) is compared to an intervention group (with the use of the KLIK PROfile). A sequential cohort design is chosen to avoid contamination between the study groups. CONCLUSIONS: Based on the positive experiences with the use of the KLIK PROfile acquired during the study we conclude that the KLIK PROfile may contribute to systematically monitor and discuss HRQOL issues during consultations. The next steps will be a comprehensive evaluation of the KLIK study data and the implementation of the KLIK PROfile in daily clinical practice in different patient groups.

Explorative study on the aftercare of pediatric brain tumor survivors: a parents' perspective.

PURPOSE: Whilst the need for aftercare for long-term sequelae of brain tumor survivors is well known and evident, information from a parent's perspective is lacking on whether the need for aftercare is detected in time, and whether the aftercare is timely initiated and meets the needs for aftercare. METHODS: A survey regarding aftercare in five domains of long-term sequelae (neurocognitive, physical, emotional, social and parenting problems) was sent to 57 parents of survivors treated for a brain tumor in our center. RESULTS: Forty-two (74%) parents participated in this study. With a mean period of 8.1 years (SD = 3.9) since start of treatment, the majority of the survivors (mean age = 14.7 years, SD = 3.8) needed aftercare in several domains of functioning. This need was highest and most met for physical sequelae (N = 34), and lowest but still substantial and least met for parental difficulties (N = 11). Parents of survivors with surgery only as treatment reported a similar need for aftercare as those of survivors with adjuvant therapy. Most of the survivors received aftercare; however, substantial delay of aftercare and self-referral for aftercare were frequently reported. Furthermore, parents showed a lack of knowledge about and use of aftercare services. CONCLUSIONS: Increased awareness for the need for psychosocial aftercare is required. Coaching, psycho-educative programs about coping with the long-term sequelae and information about available specialized aftercare services are required to meet the needs of brain tumor survivors and their parents more adequately.

Design of the Quality of Life in Motion (QLIM) study: a randomized controlled trial to evaluate the effectiveness and cost-effectiveness of a combined physical exercise and psychosocial training program to improve physical fitness in children with cancer.

BACKGROUND: Childhood cancer and its treatment have considerable impact on a child's physical and mental wellbeing. Especially long-term administration of chemotherapy and/or radiotherapy impairs physical fitness both during and after therapy, when children often present with muscle weakness and/or low cardiorespiratory fitness. Physical exercise can improve these two elements of physical fitness, but the positive effects of physical exercise might be further increased when a child's wellbeing is simultaneously enhanced by psychosocial training. Feeling better may increase the willingness and motivation to engage in sports activities. Therefore, this multi-centre study evaluates the short and long-term changes in physical fitness of a child with a childhood malignancy, using a combined physical exercise and psychosocial intervention program, implemented during or shortly after treatment. Also examined is whether positive effects on physical fitness reduce inactivity-related adverse health problems, improve quality of life, and are cost-effective. METHODS: This multi-centre randomized controlled trial compares a combined physical and psychosocial intervention program for children with cancer, with care as usual (controls). Children with cancer (aged 8-18 years) treated with chemotherapy and/or radiotherapy, and who are no longer than 1 year post-treatment, are eligible for participation. A total of 100 children are being recruited from the paediatric oncology/haematology departments of three Dutch university medical centres. Patients are stratified according to pubertal stage (girls: age ≤10 or >10 years; boys: ≤11 or >11 years), type of malignancy (haematological or solid tumour), and moment of inclusion into the study (during or after treatment), and are randomly assigned to the intervention or control group. DISCUSSION: Childhood cancer patients undergoing long-term cancer therapy may benefit from a combined physical exercise and psychosocial intervention program since it may maintain or enhance their physical fitness and increase their quality of life. However, the feasibility, patient need, and effectiveness of such a program should be established before the program can be implemented as part of standard care. TRIAL REGISTRATION NUMBER: NTR1531 (The Netherlands National Trial Register).

Double disadvantage: a case control study on health-related quality of life in children with sickle cell disease.

BACKGROUND: Low health-related quality of life (HRQoL) of children with sickle cell disease (SCD) may be associated with consequences of the disease, or with the low socio-economic status (SES) of this patient population. The aim of this study was to investigate the HRQoL of children with SCD, controlling for SES by comparing them to healthy siblings (matched for age and gender), and to a Dutch norm population. METHODS: The HRQoL of 40 children with homozygous SCD and 36 healthy siblings was evaluated by the KIDSCREEN-52. This self-report questionnaire assesses ten domains of HRQoL. Differences between children with SCD and healthy siblings were analyzed using linear mixed models. One-sample t-tests were used to analyze differences with the Dutch norm population. Furthermore, the proportion of children with SCD with impaired HRQoL was evaluated. RESULTS: In general, the HRQoL of children with SCD appeared comparable to the HRQoL of healthy siblings, while children with SCD had worse HRQoL than the Dutch norm population on five domains (Physical Well-being, Moods & Emotions, Autonomy, Parent Relation, and Financial Resources). Healthy siblings had worse HRQoL than the Dutch norm population on three domains (Moods & Emotions, Parent Relation, and Financial Resources). More than one in three children with SCD and healthy siblings had impaired HRQoL on several domains. CONCLUSION: These findings imply that reduced HRQoL in children with SCD is mainly related to the low SES of this patient population, with the exception of disease specific effects on the physical and autonomy domain. We conclude that children with SCD are especially vulnerable compared to other patient populations, and have special health care needs.

Health related quality of life of Dutch children: psychometric properties of the PedsQL in the Netherlands.

BACKGROUND: Knowledge about psychometric properties of the Pediatric Quality of Life Inventory (PedsQL) in the Netherlands is limited and Dutch reference data are lacking. Aim of the current study is to collect Dutch reference data of the PedsQL and subsequently assess reliability, socio-demographic within-group differences and construct validity. METHODS: In this study the PedsQL was administered to Dutch children aged 5 to 18 years. A socio-demographic questionnaire was completed as well. The sample consisted of three age groups: 5-7 years (parent proxy report), 8-12 years and 13-18 years (child self report). Analysis was performed with SPSS 16.0.2. A reliability analysis was done using Cronbach's alpha coefficient. Socio-demographic within-group differences were assessed by means of an ANOVA with post hoc Bonferroni correction and t-tests. Subsequently, construct validity was determined by t-tests and effect sizes. RESULTS: For 496 children PedsQL reference data were collected. PedsQL total scores were 84.18 (group 5-7), 82.11 (group 8-12) and 82.24 (group 13-18). Internal consistency coefficients ranged from .53 to .85. Socio-demographic within-group differences demonstrated that, in group 8-12, children of parents born in the Netherlands had significantly lower scores on several PedsQL subscales, compared to children of parents born in another country. With respect to construct validity, healthy children of group 5-7 and 13-18 scored significantly higher than children with a chronic health condition on all subscales, except for emotional functioning. In group 5-7, the PedsQL total score for healthy children was 85.31, whereas the same age group with a chronic health condition scored 78.80. Effect sizes in this group varied from 0.58 to 0.88. With respect to group 13-18, healthy children obtained a PedsQL total score of 83.14 and children suffering from a chronic health condition 77.09. Effect sizes in this group varied from 0.45 to 0.67. No significant differences were found in group 8-12 regarding health. CONCLUSION: The Dutch version of the PedsQL has adequate psychometric properties and can be used as a health related quality of life instrument in paediatric research in the Netherlands.

Longitudinal assessment of health-related quality of life in preschool children with non-CNS cancer after the end of successful treatment.

BACKGROUND: The aim of the study was to access Health Related Quality of Life (HRQoL) in preschool cancer survivors during the first 3 years of continuous remission after the end of successful treatment, and to identify predictors of HRQoL. PROCEDURE: Parent-reported HRQoL was assessed in 53 preschool children treated successfully for cancer, using the TAPQOL and compared with norm data. Longitudinal mixed models analyses were performed to investigate to what extent demographic and medical variables and parental psychological distress were predictive of HRQoL over time. RESULTS: Two months after the end of successful cancer treatment, survivors showed significantly (P < 0.01) more problem behavior and anxiety, and scored significantly worse (P < 0.01) on sleeping, motor functioning, positive mood and liveliness than the norm. One year after the end of treatment survivors still showed significantly (P < 0.01) more anxiety and worse motor functioning. The level of HRQoL in survivors had normalized 2 and 3 years after the end of treatment. Longer duration of treatment, bad prognosis and greater parental psychological distress were associated with worse scores on the Physical Component Score of the TAPQOL. Medical variables and parental psychological distress were not associated with the Mental Component Score. CONCLUSIONS: Survivors adjusted well to the cancer experience and HRQoL improved with time. Despite overall resilience in survivors over time, physical as well as psychosocial monitoring in follow-up is recommended. Standard aftercare should preferably include psychosocial screening, education, and counseling directed at both survivors and parents.

Health-related quality of life in children and emotional reactions of parents following completion of cancer treatment.

BACKGROUND: Completing therapy is one of the major transitions in care in the practice of pediatric oncology and, therefore, deserves special consideration. The purpose of the study was to investigate health-related quality of life (HRQOL) of pediatric patients, and emotional reactions of their parents, shortly after the end of successful treatment. METHODS: HRQOL of 126 patients, aged 1-15 years, on average 2 months after the end of successful treatment, was assessed with the TNO-AZL Pre-school Quality of life Questionnaire and the TNO-AZL Children's Quality of life Questionnaire. Emotional adjustment of 124 mothers and 111 fathers was assessed with the General Health Questionnaire and the Situation Specific Emotional Reaction Questionnaire. The outcomes of the patients and parents were compared with norm data by means of one sample t-tests, one sample sign-tests or binomial tests. RESULTS: All age groups, except patients aged 8-11 years, experienced worse HRQOL than the norm with respect to motor functioning. In addition, pre-school patients were rated worse on sleeping, appetite, stomach, skin, problem behavior, anxiety, and liveliness, and patients aged 6-7 years on autonomy and cognitive functioning. Parents reported more psychological distress than the norm. Compared to parents whose children were 1-5 years after cancer treatment, they suffered more from feelings of loneliness, helplessness, and uncertainty. CONCLUSIONS: A few months after the end of successful cancer treatment, both patients and parents appeared to experience worse well-being than the norm to a clinically relevant extent. Supporting patients and parents should not stop when treatment ends.
