Mapping child and adolescent self-reported symptom data to clinician-reported adverse event grading to improve pediatric oncology care and research

Agreement and disagreement between child-caregiver symptom and function reports in pediatric oncology

BACKGROUND/OBJECTIVE

The use of patient-reported outcomes (PRO) is increasing in pediatric clinical practice and research, including in clinical trials. Treatment teams are now able to discern differences in symptom and function reports between children with cancer and their family caregivers. Few studies, however, have quantified such differences.

DESIGN/METHODS

Children and caregivers were matched to create a dyad sample, and child/caregiver agreement of responses to the Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric symptom and function measures were examined using the established minimally important difference (MID) value (three points) derived from these measures. Latent class analysis (LCA) was then used to analyze the status/patterns of response agreement.

RESULTS

A total of 430 dyadic cases (dyads) were used for LCA modeling. Three classes of child-caregiver concordance resulted: (a) Agreement-caregiver and child within one MID (200 dyads); (b) Disagreement-caregiver underestimating symptoms (47 dyads with caregiver scores more than 1 MID lower than the child scores); and (c) Disagreement-caregiver overestimating symptoms (183 dyads with caregiver scores more than 1 MID higher than child scores).

CONCLUSION

As PRO use increases in pediatric oncology, clinician identification of child/caregiver differences on symptom and function reports will help to distinguish family perceptions of cancer treatment impact. The treatment goal, in addition to mitigating symptom and function treatment-related burdens for the child and caregiver, may now also be to discern the direction and clinical meaning of the difference within the child-parent dyad.

Longitudinal use of patient reported outcomes in pediatric leukemia and lymphoma reveals clinically relevant symptomatic adverse events

BACKGROUND

Leukemia and lymphoma (LL) are the most common cancer diagnoses of childhood with high survival rates, but not without impact on the child's functioning and quality of life. This study aimed to use patient-reported data to describe the symptomatic adverse event (AE) experiences among children with LL diagnoses.

METHODS

Two hundred and fifty seven children and adolescents aged 7-18 years with a first LL diagnosis completed the Pediatric Patient-Reported version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) and Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric measures before starting a treatment course (T1) and after the treatment (T2).

RESULTS

Fatigue was the most severe AE (68.1% at T1; 67% at T2) and caused the most interference over time. Gastrointestinal AEs were also quite common (e.g., nausea 46.3% at T1 and 48.9% at T2; abdominal pain 42.4% at T1; 46.5% at T2). In general, symptoms were present both at T1 and T2 and did not change significantly in severity or interference. The prevalence of AEs varied by LL disease group (e.g., nausea was most common in acute lymphoblastic leukemia (ALL), fatigue was most severe in ALL and Hodgkin Lymphoma (HL), acute myeloid leukemia had the fewest AEs).

CONCLUSION

Despite current supportive care regimens, many children with LL continue to report fatigue, pain, insomnia, and gastrointestinal symptoms as the most frequent or severe symptoms during therapy.

Linking the European Organisation for Research and Treatment of Cancer Item Library to the Common Terminology Criteria for Adverse Events

PURPOSE

The European Organisation for Research and Treatment of Cancer (EORTC) Item Library is an interactive online platform currently composed of 950 unique items (questions) derived from 67 patient-reported outcome (PRO) questionnaires. PROs complement clinician adverse event (AE) reporting classifications like the Common Terminology Criteria for Adverse Events (CTCAE). This work aims to create a standardized framework using the CTCAE to systematically classify symptomatic AEs from the EORTC Item Library through linking individual items to corresponding AEs.

METHODS

The EORTC Item Library items were searched for within the CTCAE (v5.0) and linked to an AE if they were described within the AE's title, description, or grading. Symptoms described in EORTC items but not located in the CTCAE were coded as missing symptoms. Other nonsymptom EORTC items, not described within the CTCAE were assigned a non-CTCAE descriptive classification. Further descriptive codes (eg, multiple issues) were allocated to enable descriptive analysis. Two raters independently coded 26.2% (n = 249) of the items. The remaining 701 items were coded by one rater and verified by the second, followed by discussion with two additional raters to reach consensus.

RESULTS

Overall, 625 (65.8%) EORTC items were linked to 208 different AEs. Three hundred sixty-nine items provide information about non-CTCAE cancer-related issues and were categorized into seven descriptive classifications, including body image; emotional impact of a symptom, diagnosis, or treatment; global health and quality of life; and impact on life and daily activities. Inter-rater agreement for independent coding was 79.1%. Bowel urgency and tenesmus were identified as missing symptoms in CTCAEv5.0.

CONCLUSION

The EORTC Item Library provides considerable coverage of CTCAE toxicities, along with other complementary issues important to patients with cancer. Using the CTCAE clinical framework to classify symptomatic PRO items may facilitate PRO selection and use in clinical trials and routine care.

Recommended scoring approach for the pediatric patient-reported outcomes version of the Common Terminology Criteria for Adverse Events

BACKGROUND

Collecting symptom, function, and adverse event (AE) data directly from children and adolescents undergoing cancer care is more comprehensive and accurate than relying solely on their caregivers or clinicians for their interpretations. We developed the pediatric patient-reported outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) measurement system with input from children, parents, and clinicians. Here, we report how we determined the recommended Ped-PRO-CTCAE item scoring approach.

METHODS

Data from 271 patients were analyzed using three scoring approaches: (a) at the AE attribute (frequency, severity, interference) using ordinal and dichotomous measures; (b) a weighted composite AE item score by AE attribute (0.5 - frequency; 1.0 - severity; 1.5 - interference); and (c) overall number of AEs endorsed. Associations of each AE attribute, AE item score, and overall AE score with the Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric measures were examined. The ability of the overall Ped-PRO-CTCAE AE score to identify patients with PROMIS symptom T-scores worse than reference population scores was assessed. Clinician preference for score information display was elicited through interviews with five pediatric oncology clinical trialists.

RESULTS

The diverse scoring approaches yielded similar outcomes, including positive correlations of the Ped-PRO-CTCAE attributes, AE item score, and the overall AEs score with the PROMIS Pediatric measures. Clinicians preferred the most granular display of scoring information (actual score reported by the child and corresponding descriptive term).

CONCLUSIONS

Although three scoring approaches yielded similar results, we recommend the AE attribute level of one score per Ped-PRO-CTCAE AE attribute for its simplicity of use in care and research.

Lack of Concordance in Symptomatic Adverse Event Reporting by Children, Clinicians, and Caregivers: Implications for Cancer Clinical Trials

PURPOSE

To examine concordance in symptomatic adverse event (AE) grading using the Common Terminology Criteria for Adverse Events (CTCAE 4.0) for clinicians and its patient-reported outcome (PRO) versions for children (Ped-PRO-CTCAE) and caregivers (Ped-PRO-CTCAE [Caregiver]).

METHODS

Children age 7-18 years with a first cancer diagnosis, their clinicians, and caregivers completed CTCAE-based measures before starting a treatment course (T1) and after the treatment (T2). Grades (0-3) were assigned by each reporter for 15 core AEs spanning physical and mental health. Mean grades were compared between reporters using two-sample t-tests; agreement was estimated using weighted kappa (κ) statistics. Multivariable mixed regression models were used to evaluate associations of clinical factors with AE reporting concordance. Significance was set at α = .05 (two-sided).

RESULTS

There were 438 child-clinician-caregiver triads with complete data at either T1 or T2. For children, the mean age was 13 years (standard deviation = 3.4), 53.7% were male, 32.6% non-White, and 56.4% had leukemia/lymphoma. At T1, clinician mean AE grades were significantly lower (ie, better) than children for all AEs and remained significantly lower at T2 except for constipation, nausea, anorexia, neuropathy, and anxiety. Caregiver mean AE grades were similar to children at T1 and significantly higher (ie, worse) at T2 for nausea, vomiting, anorexia, pain, fatigue, anxiety, and depression. Agreement for child-clinician grading was poor-to-fair at T1 (κ range, 0.08-0.34) and T2 (0.11-0.35), and for child-caregiver, was fair-to-good at T1 (0.34-0.65) and T2 (0.24-0.60). No factors were consistently associated with reporter concordance across AEs.

CONCLUSION

Compared with children, symptomatic AEs were consistently under-reported by clinicians with low agreement and over-reported by caregivers with low-moderate agreement. Direct reporting by children using Ped-PRO-CTCAE or similar measures should be routinely incorporated for toxicity assessment in clinical trials.

Incidence, severity, and preventability of adverse events during the induction of patients with acute lymphoblastic leukemia in a tertiary care pediatric hospital in Mexico

Healthcare-associated adverse events represent a heavy burden of symptoms for pediatric oncology patients. Their description allows knowing the safety and quality of the care processes in countries with limited resources. This study aimed to describe the incidence, types, severity, and preventability of adverse events occurring in pediatric patients with acute lymphoblastic leukemia during the induction phase in a tertiary care pediatric hospital in Mexico. This study analyzed a cohort based on medical records of between 2015 and 2017. Initially, information on patients and adverse events was collected; subsequently, two pediatric oncologist reviewers independently classified adverse events, severity and preventability. Agreement between reviewers was evaluated. Adverse events incidence rates were estimated by type, severity, and preventability. One-hundred and eighty-one pediatric patients pediatric patients with acute lymphoblastic leukemia were studied. An overall adverse events rate of 51.8 per 1000 patient-days was estimated, involving 81.2% of patients during induction. Most adverse events were severe or higher (52.6%). Infectious processes were the most common severe or higher adverse event (30.5%). The presence of adverse events caused 80.2% of hospital readmissions. Of the adverse events, 10.5% were considered preventable and 53.6% could be ameliorable in severity. Improving the safety and quality of the care processes of children with acute lymphoblastic leukemia is possible, and this should contribute to the mitigation and prevention of adverse events associated morbidity and mortality during the remission induction phase.

The predictive trifecta? Fatigue, pain, and anxiety severity forecast the suffering profile of children with cancer

BACKGROUND

Fatigue, pain, and anxiety, symptoms commonly experienced by children with cancer, may predict pediatric symptom suffering profile membership that is amenable to treatment.

METHODS

Three latent profiles (Low, Medium, and High symptom suffering) from 436 pediatric patients undergoing cancer care were assessed for association with three single-item symptoms and socio-demographic variables.

RESULTS

Pediatric-PRO-CTCAE fatigue, pain, and anxiety severity scores at baseline were highly and significantly associated with the Medium and High Suffering profiles comprised of PROMIS pediatric symptom and function measures. The likelihood of membership in the Medium Suffering group was 11.37 times higher for patients who experienced fatigue severity than those with did not, while experience of pain severity increased the likelihood of the child's membership in the Medium Suffering profile by 2.59 times and anxiety by 3.67 times. The severity of fatigue increased the likelihood of presence in the High Suffering group by 2.99 times while pain severity increased the likelihood of the child's membership in the High Suffering profile by 6.36 times and anxiety by 16.75 times. Controlling for experience of symptom severity, older patients were more likely to be in the Higher or Medium Suffering profile than in the Low Suffering profile; no other socio-demographic or clinical variables had a significant effect on the latent profile classification.

CONCLUSION

Clinician knowledge of the strong association between fatigue, pain, and anxiety severity and suffering profiles may help focus supportive care to improve the cancer experience for children most at risk from time of diagnosis through treatment.

Improving Guideline-Congruent Care for Chemotherapy-Induced Nausea and Vomiting Prophylaxis in Pediatric Oncology Patients

PURPOSE

Chemotherapy-induced nausea and vomiting (CINV) is a very common side effect of pediatric cancer therapy. High-quality, evidence-based, pediatric-specific guidelines for prophylaxis and treatment of CINV are available. At many centers, guideline-concordant care is uncommon. We formed a multidisciplinary quality improvement team to implement guideline-concordant care for CINV prophylaxis at our center. We present the results following the first year of our interventions.

METHODS

We planned and implemented a multipronged approach in three key phases: (1) developing and publishing an acute CINV prophylaxis pathway, (2) education of providers, and (3) updating the computerized provider order entry system. We used iterative, sequential Plan-Do-Study-Act cycles and behavioral economic strategies to improve adherence to guideline-concordant CINV prophylaxis. We focused on aprepitant usage as a key area for improvement.

RESULTS

At the beginning of the study period, < 50% of patients were receiving guideline-concordant CINV prophylaxis and < 15% of eligible patients were receiving aprepitant. After 1 year, more than 60% of patients were receiving guideline-concordant care and 50% of eligible patients were receiving aprepitant.

CONCLUSION

We describe the development and implementation of a standardized pathway for prevention of acute CINV in pediatric oncology patients. With a multidisciplinary, multifaceted approach, we demonstrate significant improvements to guideline-congruent CINV prophylaxis.

Subjective Toxicity Profiles of Children in Treatment for Cancer: A New Guide to Supportive Care?

CONTEXT

Children and adolescents with cancer experience treatment-related, subjective adverse events (AEs). Identifying distinct groups of patients who predictably experience higher prevalence of AEs could guide patient care.

OBJECTIVES

Study aims were to 1) identify groups of children and adolescents reporting AEs using the Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE); 2) determine whether demographic and clinical characteristics predict AE group membership; and 3) examine whether AE group membership was related to the distal outcome of psychological stress.

METHODS

Four hundred seventy-seven patients self-reported AEs via the Ped-PRO-CTCAE at T1 (beginning of treatment) and the PROMIS Pediatric Psychological Stress measure at T2 (7-28 days later). Latent class analysis was conducted to identify groups of patients and the relationships of the groups with demographic and clinical characteristics, and with stress.

RESULTS

Three distinct a priori unknown AE groups were identified (high AE prevalence, moderate AE prevalence, and low AE prevalence). Females, blacks, patients with high psychological stress, and patients more recently diagnosed were more likely to be in the high AE prevalence group. Gender, age, race, and time since diagnosis were associated with psychological stress.

CONCLUSION

Children with cancer are heterogeneous in experiencing subjective AEs. Gender, race, and time since diagnosis were significantly associated with higher subjective AE prevalence that may lead to psychological stress.

Validity and Reliability of the Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events

BACKGROUND

Patient-reported outcome (PRO) measurements linked to Common Terminology Criteria for Adverse Events (CTCAE) grading may improve symptom adverse event (AE) reporting in pediatric oncology trials. We evaluated construct validity, responsiveness, and test-retest reliability of the Ped-PRO-CTCAE measurement system for children and adolescents undergoing cancer care.

METHODS

A total of 482 children and adolescents (7-18 years, 41.5% not non-Hispanic white) newly diagnosed with cancer and their caregivers participated from nine pediatric oncology hospitals. Surveys were completed at 72 hours preceding treatment initiation (T1) and at follow-up (T2) approximately 7-17 days later for chemotherapy, and 4+ weeks for radiation. Psychometric analyses examined the relationship of Ped-PRO-CTCAE items (assessing 62 symptom AEs) with Patient-Reported Outcomes Measurement Information System, Memorial Symptom Assessment Scale, Lansky Play-Performance Scale, and medication use. A separate test-retest study included 46 children.

RESULTS

Ped-PRO-CTCAE and Memorial Symptom Assessment Scale were strongly correlated across age groups at T2: 7-12 years (r = 0.62-0.80), 13-15 years (r = 0.44-0.94), and 16-18 years (r = 0.65-0.98); and over time. The Ped-PRO-CTCAE was strongly correlated with Patient-Reported Outcomes Measurement Information System Pediatric measures at T2; for example, pain interference (r = 0.70, 95% confidence interval [CI] = 0.64 to 0.76), fatigue severity (r = 0.63, 95% CI = 0.56 to 0.69), and depression severity (r = 0.76, 95% CI = 0.71 to 0.81). Ped-PRO-CTCAE items differentiated children by Lansky Play-Performance Scale and by medication use. Test-retest agreement ranged from 54.3% to 93.5%.

CONCLUSIONS

This longitudinal study provided evidence for the construct validity and reliability of the core Ped-PRO-CTCAE symptom AE items relative to several established measures. Additional responsiveness data with clinical anchors are recommended. Incorporation of Ped-PRO-CTCAE in trials may lead to a better understanding of the cancer treatment experience.

Electronic symptom monitoring in pediatric patients hospitalized for chemotherapy

BACKGROUND

Using patient-reported outcomes for symptom monitoring in oncology has resulted in significant benefits for adult patients with cancer. The feasibility of this approach has not been established in the routine care of children with cancer.

METHODS

The Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) is an item library that enables children and caregivers to self-report symptoms. Ten symptom items from the Ped-PRO-CTCAE were uploaded to an online platform. Patients at least 7 years old and their caregivers were prompted by text/email message to electronically self-report daily during a planned hospitalization for chemotherapy administration. Symptom reports were emailed to the clinical team caring for the patient, but no instructions were given regarding the use of this information. Rates of patient participation and clinician responses to reports were systematically tracked.

RESULTS

The median age of the participating patients (n = 52) was 11 years (range, 7-18 years). All patients and caregivers completed an initial login, with 92% of dyads completing at least 1 additional symptom assessment during hospitalization (median, 3 assessments; range, 0-40). Eighty-one percent of participating dyads submitted symptom reports on at least half of hospital days, and 54% submitted reports on all hospital days. Clinical actions were taken in response to symptom reports 21% of the time. Most patients felt that the system was easy (73%) and important (79%). Most clinicians found symptom reports easy to understand and useful (97%).

CONCLUSIONS

Symptom monitoring using patient-reported outcome measures for hospitalized pediatric oncology patients is feasible and generates data valued by clinicians and patients.

Current status and future directions of U.S. genomic nursing health care policy

BACKGROUND

As genomic science moves beyond government-academic collaborations into routine healthcare operations, nursing's holistic philosophy and evidence-based practice approach positions nurses as leaders to advance genomics and precision health care in routine patient care.

PURPOSE

To examine the status of and identify gaps for U.S. genomic nursing health care policy and precision health clinical practice implementation.

METHODS

We conducted a scoping review and policy priorities analysis to clarify key genomic policy concepts and definitions, and to examine trends and utilization of health care quality benchmarking used in precision health.

FINDINGS

Genomic nursing health care policy is an emerging area. Educating and training the nursing workforce to achieve full dissemination and integration of precision health into clinical practice remains an ongoing challenge. Use of health care quality measurement principles and federal benchmarking performance evaluation criteria for precision health implementation are not developed.

DISCUSSION

Nine recommendations were formed with calls to action across nursing practice workforce and education, nursing research, and health care policy arenas.

CONCLUSIONS

To advance genomic nursing health care policy, it is imperative to develop genomic performance measurement tools for clinicians, purchasers, regulators and policymakers and to adequately prepare the nursing workforce.

Evolution of Hematology Clinical Trial Adverse Event Reporting to Improve Care Delivery

PURPOSE OF REVIEW

Reporting of adverse events on hematology clinical trials is crucial to understanding the safety of standard treatments and novel agents. However, despite the importance of understanding toxicities, challenges in capturing and reporting accurate adverse event data exist.

RECENT FINDINGS

Currently, adverse events are reported manually on most hematology clinical trials. Especially on phase III trials, the highest grade of each adverse event during a reporting period is typically reported. Despite the effort committed to AE reporting, studies have identified underreporting of adverse events on hematologic malignancy clinical trials, which raises concern about the true understanding of safety of treatment that clinicians have in order to guide patients about what to expect during therapy. In order to address these concerns, recent studies have piloted alternative methods for identification of adverse events. These methods include automated extraction of adverse event data from the electronic health record, implementation of trigger or alert tools into the medical record, and analytic tools to evaluate duration of adverse events rather than only the highest adverse event grade. Adverse event reporting is a crucial component of clinical trials. Novel tools for identifying and reporting adverse events provide opportunities for honing and refining methods of toxicity capture and improving understanding of toxicities patients experience while enrolled on clinical trials.

Composite grading algorithm for the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE)

BACKGROUND

The Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events is an item library designed for eliciting patient-reported adverse events in oncology. For each adverse event, up to three individual items are scored for frequency, severity, and interference with daily activities. To align the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events with other standardized tools for adverse event assessment including the Common Terminology Criteria for Adverse Events, an algorithm for mapping individual items for any given adverse event to a single composite numerical grade was developed and tested.

METHODS

A five-step process was used: (1) All 179 possible Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events score combinations were presented to 20 clinical investigators to subjectively map combinations to single numerical grades ranging from 0 to 3. (2) Combinations with <75% agreement were presented to investigator committees at a National Clinical Trials Network cooperative group meeting to gain majority consensus via anonymous voting. (3) The resulting algorithm was refined via graphical and tabular approaches to assure directional consistency. (4) Validity, reliability, and sensitivity were assessed in a national study dataset. (5) Accuracy for delineating adverse events between study arms was measured in two Phase III clinical trials (NCT02066181 and NCT01522443).

RESULTS

In Step 1, 12/179 score combinations had <75% initial agreement. In Step 2, majority consensus was reached for all combinations. In Step 3, five grades were adjusted to assure directional consistency. In Steps 4 and 5, composite grades performed well and comparably to individual item scores on validity, reliability, sensitivity, and between-arm delineation.

CONCLUSION

A composite grading algorithm has been developed and yields single numerical grades for adverse events assessed via the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events, and can be useful in analyses and reporting.
