Feasibility of three times weekly symptom screening in pediatric cancer patients.

OBJECTIVE: Primary objective was to determine the feasibility of three times weekly symptom reporting by pediatric cancer patients for eight weeks. METHODS: We included English-speaking patients 8-18 years of age with cancer. Patients were sent reminders by text or email to complete Symptom Screening in Pediatrics Tool (SSPedi) three times weekly for eight weeks. When patients reported at least one severely bothersome symptom, the symptom report was emailed to the primary healthcare team. Patient-reported outcomes were obtained at baseline, week 4 ± 1 and week 8 ± 1. Symptom documentation, intervention provision for symptoms and unplanned healthcare encounters were determined by chart review at weeks 4 and 8. The primary endpoint was feasibility, defined as at least 75% patients achieving adherence with at least 60% of SSPedi evaluations. We planned to enroll successive cohorts until this threshold was met. RESULTS: Two cohorts consisting of 30 patients (cohort 1 (n = 20) and cohort 2 (n = 10)) were required to meet the feasibility threshold. In cohort 1, 11/20 (55%) met the SSPedi completion threshold. Interventions applied after cohort 1 included engaging parents to facilitate pediatric patient self-report, offering mechanisms to remember username and password and highlighting potential benefits of symptom feedback to clinicians. In cohort 2, 9/10 (90%) met the SSPedi completion threshold and thus feasibility was met. Patient-reported outcomes and chart review outcomes were obtained for all participants in cohort 2. CONCLUSIONS: Three times weekly symptom reporting by pediatric patients with cancer for eight weeks was feasible. Mechanisms to enhance three times weekly symptom reporting were identified and implemented. Future studies of longitudinal symptom screening can now be planned.

Symptom management care pathway adaptation process and specific adaptation decisions.

BACKGROUND: There is substantial heterogeneity in symptom management provided to pediatric patients with cancer. The primary objective was to describe the adaptation process and specific adaptation decisions related to symptom management care pathways based on clinical practice guidelines. The secondary objective evaluated if institutional factors were associated with adaptation decisions. METHODS: Fourteen previously developed symptom management care pathway templates were reviewed by an institutional adaptation team composed of two clinicians at each of 10 institutions. They worked through each statement for all care pathway templates sequentially. The institutional adaptation team made the decision to adopt, adapt or reject each statement, resulting in institution-specific symptom management care pathway drafts. Institutional adaption teams distributed the 14 care pathway drafts to their respective teams; their feedback led to care pathway modifications. RESULTS: Initial care pathway adaptation decision making was completed over a median of 4.2 (interquartile range 2.0-5.3) weeks per institution. Across all institutions and among 1350 statements, 551 (40.8%) were adopted, 657 (48.7%) were adapted, 86 (6.4%) were rejected and 56 (4.1%) were no longer applicable because of a previous decision. Most commonly, the reason for rejection was not agreeing with the statement (70/86, 81.4%). Institutional-level factors were not significantly associated with statement rejection. CONCLUSIONS: Acceptability of the 14 care pathways was evident by most statements being adopted or adapted. The adaptation process was accomplished over a relatively short timeframe. Future work should focus on evaluation of care pathway compliance and determination of the impact of care pathway-consistent care on patient outcomes.

Reliability and validity of proxy-SSPedi and mini-SSPedi in pediatric patients 2-7 years receiving cancer treatments.

BACKGROUND: Symptom Screening in Pediatrics Tool (SSPedi) was developed for symptom screening by children 8-18 years. Objectives were to evaluate the reliability and validity of proxy-SSPedi and self-report mini-SSPedi for younger children. METHODS: This multi-center study enrolled guardians of children 2-7 years receiving cancer treatments (proxy-SSPedi) and their children 4-7 years (mini-SSPedi). The two populations were: (1) More symptomatic group where children were receiving active cancer treatment and were in hospital or clinic for four consecutive days; and (2) Less symptomatic group where children were receiving maintenance therapy for acute lymphoblastic leukemia or had completed cancer therapy. Proxy-SSPedi or mini-SSPedi were completed with measures of mucositis, nausea, pain, quality of life and overall symptoms. Respondents in the more symptomatic group repeated proxy-SSPedi/mini-SSPedi and a global symptom change scale 3 days later. RESULTS: There were 402 guardians and 326 children included in the analysis. Test re-test reliability of proxy-SSPedi showed intraclass correlation coefficient (ICC) 0.83 (95% confidence interval (CI) 0.72-0.90). Mean difference in proxy-SSPedi between more and less symptomatic groups was 9.7 (95% CI 8.3-11.1). Proxy-SSPedi was responsive to change and hypothesized relationships between measures were observed. With a priori threshold ≥0.6, inter-rater ICC among all dyads and those 6-7 years were 0.54 (95% CI 0.45-0.62) and 0.62 (95% CI 0.50-0.71) respectively. Among participating children, other hypothesized reliability and validity thresholds were generally met. CONCLUSIONS: Proxy-SSPedi is reliable, valid and responsive in children 2-7 years old receiving cancer treatments. Mini-SSPedi can be used for children 6-7 years of age.

Creating and adapting an infection management care pathway in pediatric oncology.

PURPOSE: While care pathways based upon clinical practice guidelines (CPGs) are important, little is known about optimal approaches to development and adaptation in pediatric oncology. Objectives were to develop care pathway templates for pediatric cancer supportive care that are based upon CPGs and to adapt an infection management care pathway for use at a single institution. METHODS: Study phases were as follows: (1) creation of care pathway templates across multiple supportive care topics; (2) refinement of the infection management care pathway template by interviewing pediatric oncology clinicians at a single institution; and (3) adaptation of the infection management care pathway template for use at a different institution. RESULTS: Informed by seven CPGs, an initial iteration of the infection management care pathway template was created. This template was then refined based upon 20 interviews with pediatric oncology clinicians. Adaptation of the infection management care pathway template for use at a different institution required many changes to improve its clinical usability. Specificity and additional information not considered by the source CPGs were incorporated. CONCLUSION: We developed a process to create care pathway templates across multiple supportive care topics in pediatric oncology and to refine and adapt the infection management care pathway. While we found that the process was feasible, we also identified the need to substantially modify the care pathway during the adaptation process to consider scenarios not addressed by the source CPGs. Future work should measure implementation success.

Identifying clinical practice guidelines for symptom control in pediatric oncology.

BACKGROUND: Children with cancer commonly experience distressing symptoms such as pain, fatigue and nausea. Improvements in patient outcomes have been associated with implementation of clinical practice guideline-consistent care across several domains. The objective of this study was to develop a process to identify symptom management clinical practice guidelines (CPGs) applicable to children and adolescents receiving cancer treatments. METHODS: We focused on identifying CPGs to manage 15 symptoms. The process defined three Tiers of CPGs based upon applicability to pediatric cancer patients and ease of identification: Tier 1: endorsed by the Children's Oncology Group; Tier 2: housed in the Emergency Care Research Institute repository, or developed by the American Society of Clinical Oncology or National Institute for Health and Care Excellence; and Tier 3: identified by systematic review. We first searched for CPGs published 2015-2020 and identified Tiers 1 or 2 CPGs. If unavailable or scope was too narrow, we proceeded to Tier 3. If CPGs were not identified, we repeated these steps for CPGs published 2010-2014. RESULTS: There were six Tier 1 and 13 Tier 2 CPGs published 2015-2020 across the 15 symptoms. Four symptoms required progression to Tier 3 because CPGs were absent (anger) or because scope was too narrow (pain, anorexia/excessive hunger and diarrhea). The systematic review identified three CPGs for pain and none for the other three symptoms. In total, CPGs were identified for 14 of 15 symptoms. None were identified for anger. CONCLUSION: We created a process to identify supportive care CPGs for pediatric cancer symptom management and were able to identify CPGs that addressed 14 of 15 symptoms. Future work should focus on evaluating implementation techniques for these CPGs and determining the impact of these CPGs on provider and patient outcomes.

Barriers to symptom management care pathway implementation in pediatric Cancer.

BACKGROUND: Objectives were to describe barriers to pediatric cancer symptom management care pathway implementation and the impact of the COVID-19 pandemic on clinical research evaluating their implementation. METHODS: We included 25 pediatric oncology hospitals in the United States that supported a grant submission to perform a cluster randomized trial in which the intervention encompassed care pathways for symptom management. A survey was distributed to site principal investigators prior to randomization to measure contextual elements related to care pathway implementation. Questions included the inner setting measures of the Consolidated Framework for Implementation Research (CFIR), study-specific potential barriers and the impact of the COVID-19 pandemic on clinical research. The Wilcoxon rank sum test was used to compare characteristics of institutions that agreed that their department supported the implementation of symptom management care pathways vs. institutions that did not agree. RESULTS: Of the 25 sites, one withdrew because of resource constraints and one did not respond, leaving 23 institutions. Among the seven CFIR constructs, the least supported was implementation climate; 57% agreed there was support, 39% agreed there was recognition and 39% agreed there was prioritization for symptom management care pathway implementation at their institution. Most common barriers were lack of person-time to create care pathways and champion their use (35%), lack of interest from physicians (30%) and lack of information technology resources (26%). Most sites reported no negative impact of the COVID-19 pandemic across research activities. Sites with fewer pediatric cancer patients were more likely to agree that staff are supported to implement symptom management care pathways (P = 0.003). CONCLUSIONS: The most commonly reported barriers to implementation were lack of support, recognition and prioritization. The COVID-19 pandemic may not be a major barrier to clinical research activities in pediatric oncology.

Development and utility assessment of a machine learning bloodstream infection classifier in pediatric patients receiving cancer treatments.

BACKGROUND: Objectives were to build a machine learning algorithm to identify bloodstream infection (BSI) among pediatric patients with cancer and hematopoietic stem cell transplantation (HSCT) recipients, and to compare this approach with presence of neutropenia to identify BSI. METHODS: We included patients 0-18 years of age at cancer diagnosis or HSCT between January 2009 and November 2018. Eligible blood cultures were those with no previous blood culture (regardless of result) within 7 days. The primary outcome was BSI. Four machine learning algorithms were used: elastic net, support vector machine and two implementations of gradient boosting machine (GBM and XGBoost). Model training and evaluation were performed using temporally disjoint training (60%), validation (20%) and test (20%) sets. The best model was compared to neutropenia alone in the test set. RESULTS: Of 11,183 eligible blood cultures, 624 (5.6%) were positive. The best model in the validation set was GBM, which achieved an area-under-the-receiver-operator-curve (AUROC) of 0.74 in the test set. Among the 2236 in the test set, the number of false positives and specificity of GBM vs. neutropenia were 508 vs. 592 and 0.76 vs. 0.72 respectively. Among 139 test set BSIs, six (4.3%) non-neutropenic patients were identified by GBM. All received antibiotics prior to culture result availability. CONCLUSIONS: We developed a machine learning algorithm to classify BSI. GBM achieved an AUROC of 0.74 and identified 4.3% additional true cases in the test set. The machine learning algorithm did not perform substantially better than using presence of neutropenia alone to predict BSI.

Development of the SPARK family member web pages to improve symptom management for pediatric patients receiving cancer treatments.

BACKGROUND: Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK) is a web-based application that facilitates symptom screening and access to supportive care clinical practice guidelines (CPGs) for children and adolescents receiving cancer treatments. Objective was to develop SPARK family member web pages for pediatric patient family members accessing: (1) proxy symptom screening and symptom reports, and (2) care recommendations for symptom management based on CPGs. METHODS: SPARK family member web pages were developed and included access to symptom screening and care recommendations sections. Care recommendations for fatigue and mucositis were created. These were iteratively refined based upon cognitive interviews with English-speaking family members ≥16 years of age until less than two participants incorrectly understood sections as adjudicated by two independent raters. RESULTS: A total of 100 family members were enrolled who evaluated the SPARK family member web pages (n = 40), fatigue care recommendation (n = 30) and mucositis prevention care recommendation (n = 30). Among the last 10 participants, none said that the SPARK family member web pages were hard or very hard to use, one incorrectly understood one web page, none said either care recommendation was hard to understand and none were incorrect in their understanding of the care recommendations. CONCLUSIONS: We successfully developed SPARK web pages for use by family members of pediatric patients receiving cancer treatments. We also developed a process for translating CPG recommendations designed for healthcare professionals to lay language. The utility of SPARK family member web pages after clinical implementation could be a focus for future research.

Feasibility of a randomized controlled trial of symptom screening and feedback to healthcare providers compared with standard of care using the SPARK platform.

PURPOSE: Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK) is a web-based application that enables symptom screening and access to clinical practice guidelines for symptom management. Objective was to determine the feasibility of a randomized trial of daily symptom screening for 5 days among children receiving cancer treatments. METHODS: We included English-speaking pediatric cancer and hematopoietic stem cell transplantation (HSCT) patients who were 8-18 years of age at enrollment and who were expected to be in the hospital or in clinic daily for five consecutive days. We randomized children to either undergo daily symptom screening with symptom reports provided to the healthcare team using the SPARK vs. standard of care. The primary endpoint was feasibility, defined as being able to enroll at least 30 participants within 1 year, and among those randomized to intervention, at least 75% completing symptom screening on at least 60% of on-study days. RESULTS: From July 2018 to November 2018, we enrolled and randomized 30 participants. The median age at enrollment was 12.5 (range 8-18) years. Among the intervention group, the median number of days Symptom Screening in Pediatrics Tool (SSPedi) was completed at least once was 5 (range 4 to 5), with one participant missing 1 day of symptom screening. Among all participants, baseline and day 5 SSPedi scores were obtained in 29/30 participants. CONCLUSION: A randomized trial of the SPARK with daily symptom screening for 5 days was feasible. It is now appropriate to proceed toward a definitive multi-center trial to test the efficacy of SPARK to improve symptom control.

Changes in hunger among pediatric patients with cancer and hematopoietic stem cell transplantation recipients.

PURPOSE: Change in hunger is a common and bothersome symptom among pediatric patients receiving cancer treatments. Objectives were to describe how children and adolescents receiving cancer treatments experience changes in hunger, factors associated with both increases and decreases in hunger, and coping strategies used by these patients. METHODS: We enrolled children and adolescents 4-18 years of age with cancer or hematopoietic stem cell transplantation (HSCT) recipients who were actively receiving treatment or who had completed therapy. Using a single, qualitative, semi-structured interview, we asked participants about the experience of increases or decreases in hunger, including characteristics of the change and identified coping strategies. RESULTS: There were 50 children enrolled; 25 (50%) were 4-10 years of age and 33 (66%) were boys. Most often, patients associated an increase in hunger with corticosteroid administration, while other treatments, accompanying symptoms, inactivity, and the hospital environment were associated with a decrease in hunger. Many reported that no coping strategies were successful. For those who did report successful strategies to manage an increase in hunger, these included sleep and having food available. Strategies used to manage a decrease in hunger included anti-emetic medications, increased caloric intake, varied food choices, encouragement to eat, scheduling or tracking of meals, and physical activity. CONCLUSIONS: Both increases and decreases in hunger were commonly described. Some coping strategies were reported to be successful. Further research should identify and test interventions to manage changes in hunger in pediatric cancer patients.

Longitudinal evaluation of Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK), a symptom screening and management application.

BACKGROUND: Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK) is a web application focused on improving symptom control. It enables pediatric cancer and hematopoietic stem cell transplant (HSCT) patients to self-report and track symptoms, and allows healthcare professionals to access guidelines for symptom management. Objective was to determine the feasibility of longitudinal collection of symptom data. METHODS: In this longitudinal, single-armed feasibility study, respondents were children 8-18 years of age with cancer or pediatric HSCT recipients. Participants completed symptom reporting daily for 5 days. Cognitive interviews were conducted on day 5. Quantitative evaluation included SPARK ease of use and understandability of SPARK reports. Qualitative feedback on facilitators and barriers to daily symptom screening was solicited. Feasibility was defined as ≥75% of participants completing symptom screening on at least 60% of on-study days during the five-day study. RESULTS: Among the 30 children enrolled, the median number of days SSPedi was completed at least once was 5 (range 3 to 5). Overall, 28/29 (96.6%) thought completing symptom screening using SPARK was easy or very easy. All participants understood SPARK symptom reports. Severe symptoms was the most common barrier to daily reporting while an alarm reminder system was the most commonly identified facilitator. CONCLUSIONS: Daily completion of symptom screening using SPARK over 5 days was feasible in children aged 8 to 18 years with cancer and pediatric HSCT recipients. SPARK is now appropriate for use in randomized trials to evaluate the effect of symptom screening and symptom feedback.

Development of mini-SSPedi for children 4-7 years of age receiving cancer treatments.

BACKGROUND: The Symptom Screening in Pediatrics Tool (SSPedi) is valid for assessing symptoms in children aged 8-18 years receiving cancer treatments. The objective was to develop a new self-report symptom screening tool for children receiving cancer treatments who are 4-7 years of age (mini-SSPedi), based on SSPedi. METHODS: Respondents were children with cancer or pediatric hematopoietic stem cell transplantation (HSCT) recipients who were 4-7 years of age. We included the same 15 symptoms contained in SSPedi. Using cognitive interviewing, we developed mini-SSPedi in three phases and made decisions based upon respondent understanding. First, we developed questionnaire structure regarding recall period, concept of bother and response option format. Second, we determined wording of each symptom. Third, we evaluated the entire mini-SSPedi instrument for understanding and ease of completion. RESULTS: We enrolled 100 participants in total and included 30, 40 and 30 in each of the three phases. Questionnaire structure was satisfactory with a recall period of "today" and a faces-based 3-point Likert scale. Bother was well-understood. Five symptoms required modification to achieve satisfactory understanding while the remaining 10 SSPedi symptoms did not require modification. Among the last 10 children enrolled, all understood each mini-SSPedi item and none thought mini-SSPedi was hard to complete. CONCLUSION: We developed a symptom screening tool for children with cancer and pediatric HSCT recipients between 4 and 7 years of age that is understandable and easy to complete. Future work will evaluate the psychometric properties of mini-SSPedi and develop an electronic version of the instrument.

Optimizing symptom control in children and adolescents with cancer.

There is growing recognition of the degree to which symptoms negatively impact on children receiving cancer treatments. A recent study described that almost all inpatient pediatric oncology patients are experiencing at least one bothersome symptom and almost 60% are experiencing at least one severely bothersome symptom. Poor symptom control occurs because of challenges with communication of bothersome symptoms to clinicians, lack of clinical practice guidelines (CPGs) for most of these symptoms, and failure to administer preventative and therapeutic interventions known to be effective for symptom control. This article reviews approaches used to improve symptom control for children receiving cancer treatments. Areas addressed include systematic symptom screening and creation of CPGs for symptom management. Challenges with electronic health integration are also addressed. Several multi-symptom assessment scales have been developed but none have yet been used to directly influence patient management. The number of CPGs applicable to symptom control in pediatric oncology is increasing but remains small. Improving the creation of and adherence to CPGs for symptom management is an important priority. Finally, identifying ways that symptom management systems can be integrated into clinical work flows is essential; these will likely need to focus on electronic health records.

Changes in taste among pediatric patients with cancer and hematopoietic stem cell transplantation recipients.

PURPOSE: Changes in taste is a common bothersome symptom in children receiving cancer treatments. However, little is known about how pediatric cancer patients experience this symptom. The objective was to describe how children receiving cancer treatments experience taste alterations and the approaches they use to address the issue. METHODS: In this qualitative study, we included English-speaking children 4-18 years of age with cancer or hematopoietic stem cell transplantation recipients who were actively receiving cancer treatment or who had completed therapy. Using a semi-structured questionnaire, we asked questions about the experience of altered taste sensation. We asked about its characteristics, impacts and identified coping strategies. RESULTS: We included 50 children. Children experienced changes in taste in a heterogeneous fashion although commonly described food as tasting "different", "not right" or "funny". While change in food preferences due to taste alterations was common, specific choices varied. Many found changes started with treatment initiation or mid-way through treatment, and some found that symptoms persisted up to 9 months following treatment completion. Actions taken to address taste changes were sucking on candy, brushing teeth and modifying food choices. CONCLUSIONS: The experience of changes in taste was common yet highly variable in its presentation and resultant changes in food preferences. Taste changes did not always resolve soon after treatment completion. Future research should identify ways to manage this symptom in pediatric cancer patients.

Initial development of Supportive care Assessment, Prioritization and Recommendations for Kids (SPARK), a symptom screening and management application.

BACKGROUND: We developed Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK), a web-based application designed to facilitate symptom screening by children receiving cancer treatments and access to supportive care clinical practice guidelines primarily by healthcare providers. The objective was to describe the initial development and evaluation of SPARK from the perspective of children. IMPLEMENTATION: Development and evaluation occurred in three phases: (1) low fidelity focused on functionality, (2) design focused on "look and feel" and (3) high fidelity confirmed functionality and design. Cognitive interviews were conducted with children receiving cancer treatments 8-18 years of age. Evaluation occurred after every five interviews and changes were guided by a Review Panel. Quantitative evaluation included SPARK ease of use and understandability of SPARK reports. RESULTS: The number of children included by phase were: low fidelity (n = 30), design (n = 30) and high fidelity (n = 30). Across phases, the median age was 13.2 (range 8.5 to 18.4) years. During low-fidelity and design phases, iterative refinements to SPARK improved website navigation, usability and likability from the perspective of children and established symptom report design. Among the last 10 children enrolled to high-fidelity testing, all (100%) understood how to complete symptom screening, access reports and interpret reports. Among these 10 respondents, all (100%) found SPARK easy to use and 9 (90%) found SPARK reports were easy to understand. CONCLUSIONS: SPARK is a web-based application which is usable and understandable, and it is now appropriate to use for research. Future efforts will focus on clinical implementation of SPARK.

Symptom documentation and intervention in paediatric cancer care-association with severity: observational study.

OBJECTIVES: Primary objectives were to determine the relationship between prevalence of symptom documentation and intervention provision, and increasing severity of bothersome symptoms, as identified by guardians using guardian-reported Symptom Screening in Pediatrics Tool (proxy-SSPedi), which is validated and measures the extent of bothersome symptoms in paediatric patients with cancer. METHODS: We included guardians of children 2-7 years of age receiving cancer treatments and seen in hospital daily for 4 consecutive days. Guardians reported proxy-SSPedi at study enrolment and 3 days later. Chart review was performed between the day prior and the day following proxy-SSPedi completion. Symptom documentation and intervention provision were determined by two independent abstractors. RESULTS: We enrolled 190 guardians who provided 371 proxy-SSPedi assessments in 190 children. The most common severely bothersome symptoms were 'feeling tired', 'feeling more or less hungry than they usually do' and 'feeling cranky or angry'. Among those with increasing severity of bother, documentation was significantly more common for 12 symptoms while intervention was significantly more common for 7 symptoms. Intervention was not significantly more common with increasing severity of bother due to 'feeling tired', 'feeling more or less hungry than they usually do' and 'feeling cranky or angry'. CONCLUSIONS: Symptom documentation was generally more common in patients with severely bothersome symptoms. Intervention was not more common among those with increasing severity of bother due to fatigue, changes in hunger or anger, which were the most common severely bothersome symptoms. Future efforts should focus on facilitating intervention provision to patients with bothersome symptoms.

Influence of participant and reviewer characteristics in application scores for a hematology research training program.

The American Society of Hematology Clinical Research Training Institute (CRTI) is a clinical research training program with a competitive application process. The objectives were to compare application scores based on applicant and reviewer sex and underrepresented minority (URM) status. We included applications to CRTI from 2003 to 2019. The application scores were transformed into a scale from 0 to 100 (100 was the strongest). The factors considered were applicant and reviewer sex and URM status. We evaluated whether there was an interaction between the characteristics and time related to application scores. In total, 713 applicants and 2106 reviews were included. There was no significant difference in scores according to applicant sex. URM applicants had significantly worse scores than non-URM applicants (mean [standard error] 67.9 [1.56] vs 71.4 [0.63]; P = .0355). There were significant interactions between reviewer sex and time (P = .0030) and reviewer URM status and time (P = .0424); thus, results were stratified by time. For the 2 earlier time periods, male reviewers gave significantly worse scores than did female reviewers; this difference did not persist for the most recent time period. The URM reviewers did not give significantly different scores across time periods. URM applicants received significantly lower scores than non-URM applicants. The impact of reviewer sex and URM status changed over time. Although male reviewers gave lower scores in the early periods, this effect did not persist in the late period. Efforts are required to mitigate the impact of applicant URM status on application scores.

Describing taste changes and their potential impacts on paediatric patients receiving cancer treatments.

OBJECTIVES: Taste changes are common among paediatric patients receiving cancer treatments although specific descriptions and associations are uncertain. Primary objective was to describe the number of paediatric patients receiving cancer therapies who experienced taste changes, its impact on food intake and enjoyment of eating, and coping strategies. METHODS: This was a cross-sectional study that included English-speaking paediatric patients aged 4-18 years with a diagnosis of cancer or haematopoietic stem cell transplantation recipients receiving active treatment. Using a structured interview, we asked participants about their experience with taste changes, impacts and coping strategies. The respondent was the paediatric patient. RESULTS: We enrolled 108 patients; median age was 11 years (IQR 8-15). The taste changes reported yesterday or today were food tasting bland (34%), bad (31%), different (27%), bitter (25%), extreme (19%), metallic (15%) or sour (12%). Taste changes were associated with decreased food intake (31%) and decreased enjoyment in eating (25%) yesterday or today. The most common coping strategies were eating food they liked (42%), eating strong-tasting food (39%), drinking liquids (35%), brushing teeth (31%) and sucking on candy (25%). Factors significantly associated with food tasting bad were as follows: older age (p=0.003), shorter time since cancer diagnosis (p=0.027), nausea and vomiting (p=0.008) and mucositis (p=0.009). CONCLUSIONS: Among paediatric patients receiving cancer treatments, taste changes were common and were associated with decreased food intake and enjoyment in eating. Common coping strategies were described. Reducing nausea, vomiting and mucositis may improve taste changes.

Development and validation of the SickKids Enterprise-wide Data in Azure Repository (SEDAR).

Objectives: To describe the processes developed by The Hospital for Sick Children (SickKids) to enable utilization of electronic health record (EHR) data by creating sequentially transformed schemas for use across multiple user types. Methods: We used Microsoft Azure as the cloud service provider and named this effort the SickKids Enterprise-wide Data in Azure Repository (SEDAR). Epic Clarity data from on-premises was copied to a virtual network in Microsoft Azure. Three sequential schemas were developed. The Filtered Schema added a filter to retain only SickKids and valid patients. The Curated Schema created a data structure that was easier to navigate and query. Each table contained a logical unit such as patients, hospital encounters or laboratory tests. Data validation of randomly sampled observations in the Curated Schema was performed. The SK-OMOP Schema was designed to facilitate research and machine learning. Two individuals mapped medical elements to standard Observational Medical Outcomes Partnership (OMOP) concepts. Results: A copy of Clarity data was transferred to Microsoft Azure and updated each night using log shipping. The Filtered Schema and Curated Schema were implemented as stored procedures and executed each night with incremental updates or full loads. Data validation required up to 16 iterations for each Curated Schema table. OMOP concept mapping achieved at least 80 % coverage for each SK-OMOP table. Conclusions: We described our experience in creating three sequential schemas to address different EHR data access requirements. Future work should consider replicating this approach at other institutions to determine whether approaches are generalizable.

Mindfulness-Based Interventions for Symptom Management in Children and Adolescents With Cancer: A Systematic Review.

Psychological interventions have shown benefit in reducing symptoms in children and adolescents with cancer. More recently, mindfulness-based interventions (MBIs) have been shown to be a promising approach to symptom intervention in adolescents with chronic illnesses. In this systematic review, we aimed to describe MBIs or focused-breathing interventions that have been used to treat symptoms in children receiving cancer therapy. A systematic review was conducted using MEDLINE/PubMed, EMBASE, CINAHL, and PsycINFO from inception to September 2019. We identified relevant articles in which MBIs or focused-breathing interventions were the primary interventions delivered to improve symptoms in children or adolescents with cancer. Six studies met the inclusion criteria. MBIs included controlled breathing and belly breathing. Intervention effects were found to be beneficial with regard to symptoms that included procedural pain, distress, and quality of life. The interventions were generally well accepted and beneficial. All studies suffered limitations because of methodological flaws, including the lack of randomization, and small sample sizes. Despite the small numbers of studies and participants, MBIs delivered to children with cancer may have beneficial effects on certain symptoms. Implications for future research include interventions tailored to the specific symptom burden. Studies must aim to increase sample sizes as well as to include individuals at high risk for severe symptoms.
