Perceptions of chemotherapy calendar creation among US pediatric oncologists

BACKGROUND

An effective chemotherapy calendar system between the clinician and the patient/caregiver can improve patient-centered outcomes. There is lack of research on how chemotherapy calendars are created and what aspects are important to pediatric oncology physicians.

PROCEDURE

In an online survey of pediatric oncology physicians, we evaluated institutional practices, perceptions of chemotherapy calendar creation, and desires for future tools. A total of 220 survey participants provided data (10.4% participant response rate) from 123 institutions (53.5% represented institutions).

RESULTS

Participants indicated that 72% always or most of the time their institution provides a chemotherapy calendar, most commonly at the start of a new cycle (90%) or with a dosing change (68%). Factors such as the health literacy of the family, prior nonadherence, type of cancer, and desire of the family affected the creation decision. Advanced practice providers (45%) or nurse coordinator/navigators (43%) were most likely to create the chemotherapy calendar. No significant difference was found between the likelihood of creating a chemotherapy calendar and institutional size (p = .09) or physician years in practice (p = .26). Approximately 95% of participants indicated chemotherapy calendar creation software that improved ease and efficiency would be moderately to extremely useful.

CONCLUSION

Future efforts should focus on co-design of an efficient and effective chemotherapy calendar by engaging with nursing and advanced practice providers along with caregivers of children with cancer.

Impact of Paired Central and Peripheral Blood Cultures in Children With Cancer

Children with cancer require central venous access which carries risk for line-related infections. The necessity of peripheral and central blood cultures is debated for those with fevers. We evaluated and described results for first episode of paired blood cultures from children with cancer who have a central venous line using retrospective database. Blood culture results, laboratory data, and medical outcomes were included. Descriptive analyses of blood culture results and clinical data were performed. There were 190 episodes of paired positive blood cultures with 167 true positive episodes. Of the true positive episodes, 104 (62.3%) were positive in both central and peripheral cultures, 42 (25.1%) were positive in central only cultures, and 21 (12.6%) were positive in peripheral cultures only. Intensive care unit admission within 48 hours after blood cultures (n=33) differed significantly: 28.7% for both central and peripheral, 10% for central only, and 0% for peripheral only (P=0.009). Central line removal (n=34) differed by type of positivity but was not significant: 22.1% for both central and peripheral, 23.8% for central only, and 4.8% for peripheral only (P=0.15). Peripheral blood cultures provided important medical information yet had differences in short-term clinical outcomes. Further evaluation of medical decision making is warranted.

Co-Design and Testing of mHealth App to Support Caregivers in the Medical Management of their Child with Cancer (Preprint)

Background

Caregivers face new challenges and tasks when their child is diagnosed with cancer, which can be overwhelming. Mobile technology has the capacity to provide immediate support at their fingertips to aid in tracking symptoms, managing medication, and planning for emergencies.

Objective

The objective of this study is to engage directly with end users and proxies to co-design and create a mobile technology app to support caregivers in the medical management of their child with cancer.

Methods

We engaged directly with caregivers of children with cancer and pediatric oncology nurse coordinators (proxy end users) to co-design and create the prototype of the Cope 360 mobile health app. Alpha testing was accomplished by walking the users through a series of predetermined tasks that encompassed all aspects of the app including tracking symptoms, managing medications, and planning or practicing for a medical emergency that required seeking care in the emergency department. Evaluation was accomplished through recorded semistructured interviews and quantitative surveys to capture demographic information and measure the system usability score. Interviews were transcribed and analyzed iteratively using NVivo (version 12; QSR International).

Results

This study included 8 caregivers (aged 33-50 years) of children with cancer, with most children receiving chemotherapy, and 6 nurse coordinators, with 3 (50%) of them having 11 to 20 years of nursing experience. The mean system usability score given by caregivers was 89.4 (95% CI 80-98.8). Results were grouped by app function assessed with focus on specific attributes that were well received and those that required refinement. The major issues requiring refinement included clarity in the medical information and terminology, improvement in design of tasks, tracking of symptoms including adjusting the look and feel of certain buttons, and changing the visual graph used to monitor symptoms to include date anchors.

Conclusions

The Cope 360 app was well received by caregivers of children with cancer but requires further refinement for clarity and visual representation. After refinement, testing among caregivers in a real-world environment is needed to finalize the Cope 360 app before its implementation in a randomized controlled trial.

Title: The Children's Oncology Planning for Emergencies (COPE) Tool: Prototyping with Caregivers of Children with Cancer

As part of a larger project to co-design and create a mHealth tool to support caregivers of children with cancer, we performed a pilot, qualitative study. For this portion of the project, we engaged with caregivers of children with cancer to co-create and refine a low-fidelity prototype of the Children's Oncology Planning for Emergencies mHealth tool. Testing was accomplished through recorded semi-structured interviews with each caregiver as they interacted with a low-fidelity wireframe using Adobe Xd. Through the engagement of our key stakeholders, we were able to refine the COPE tool to provide the key elements they desired including pertinent patient medical information, checklist for planning when seeking urgent care, and coordination of care with the medical team and other caregivers.

Variation in hospital admission from the emergency department for children with cancer: A Pediatric Health Information System study

BACKGROUND

Children with cancer experience a wide range of conditions that require urgent evaluation in the emergency department (ED), yet variation in admission rates is poorly documented.

PROCEDURE

We performed a retrospective cohort study using the Pediatric Health Information System of ED encounters by children with cancer between July 2012 and June 2015. We compared demographics for admitted versus discharged using univariate statistics, and calculated admission rates by hospital, diagnosis, day of the week, and weekend versus weekday. We assessed the degree of interhospital admission rates using the index of dispersion (ID).

RESULTS

Children with cancer had 60 054 ED encounters at 37 hospitals. Overall, 62.5% were admitted (range 43.2%-92.1%, ID 2.6) indicating overdispersed admission rates with high variability. Children with cancer that visited the ED for a primary diagnosis of fever experienced the largest amount of variability in admission with rates ranging from 10.4% to 74.1% (ID 8.1). Less variability existed among hospital admission rates for both neutropenia (range 60%-100%, ID 1.0) and febrile neutropenia (FN) (range 66.7%-100%, ID 0.83). Admission rates by day of the week did not demonstrate significant variability for any of the scenarios examined (overall P = 0.91). There were no differences by weekend versus weekday either (overall P = 0.52).

CONCLUSION

The percentage of children with cancer admitted through the ED varies widely by institution and diagnosis. Standardization of best practices for children with cancer admitted through the ED should be an area of continued improvement.

Variation in hospital admission of sickle cell patients from the emergency department using the Pediatric Health Information System

BACKGROUND

Universal newborn screening and improved treatment options have led to increased survival in sickle cell disease (SCD). However, patients with SCD still rely heavily on acute care services.

OBJECTIVE

To determine the variation seen in hospitalizations for the top complaints for ED visits for children with SCD nationally.

METHODS

We performed a retrospective review of the Pediatric Health Information Systems (PHIS) Database between October 2011 and September 2015. Emergency department (ED) encounters were selected by using International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) codes for SCD with and without crisis, fever, and pain. Univariate analyses were performed, as well as index of dispersion (ID) to assess variation by day of the week and region. ANOVA and t-test were used to determine statistical significance.

RESULTS

A total of 68 661 ED encounters at 36 hospitals met the criteria for inclusion. Of those encounters, 50.1% were admitted to the hospital. Pain and fever were the most common primary diagnoses among this population. Although variation in hospitalization was seen overall, as well as for a primary diagnosis of pain or fever, this variation was not explained by weekday/weekend designation.

CONCLUSION

The results of our study confirm pain and fever as the most common primary diagnoses for children with SCD who seek acute care, as well as demonstrate that while significant variation in hospitalization exists, it is not associated with day of the week. Further studies to elucidate patient- and hospital-level factors that influence admission variation are necessary.

Identifying patient-centered outcomes for children with cancer and their caregivers when they seek care in the emergency department

BACKGROUND

Children with cancer have high utilization of the emergency department (ED), but little is known about which outcomes are most important to them and their caregivers when they seek care in the ED.

PROCEDURE

A qualitative evaluation of ED experience for children with cancer and their caregivers was performed using self-reported interactive toolkits. Eligible participants included children with cancer (ages 11-19) and caregivers of children with cancer whose child received cancer therapy within the last year and had an ED visit within the last 2 years. Eligible participants received toolkits by mail and received incentives if they completed the toolkit. Toolkits were transcribed, thematically coded, and iteratively analyzed using Nvivo 11.0 software.

RESULTS

There were 26 toolkits received-seven by children aged 11-17 years and 19 by caregivers (11 with children aged 2-7 years, eight with children aged 11-17 years). About half were from within 1 h of their treating institution. The most important outcomes to this population included system-level issues (eg, cleanliness of space, timeliness of evaluation) and oncology-provider- and ED-provider-level issues (eg, ability to access port-a-caths, quality of communication). Participants also identified outcomes that were within the control of the patient/caregiver, such as improving their sense of preparedness.

CONCLUSION

The important outcomes to children with cancer and their caregivers when they seek care in the ED are distinct from current quality metrics. Future research should focus on the development and validation of a patient-centered outcomes tool.

A survey of mobile technology usage and desires by caregivers of children with cancer

BACKGROUND

The use of mobile health (mHealth) has grown exponentially, even by caregivers of vulnerable populations. The study objective was to understand mobile technology usage, barriers, and desires by caregivers of children with cancer.

PROCEDURE

Paper surveys were mailed to caregivers of children diagnosed with cancer at Riley Hospital for Children between June 2015 and June 2017. The survey contained 13 questions, both fixed and open-ended, and was sent in both English and Spanish up to three times.

RESULTS

Respondents (n = 121) were primarily parents (93.2%), median age was 40.7 years (range 23-63), and most were white, non-Hispanic (74.4%). The majority made under $100,000 annual household income (72.9%) and had an education of at least some college or greater (74.5%). Nearly all owned a smart phone (99.2%) and most (61.2%) owned a tablet. Among operating systems, the majority used iOS (62.8%), while 49.6% used Android. About a third (37.1%) reported no barriers to mobile technology use, but 22.4% experienced "data limitations." Overall, 86.2% wanted at least one medical management website/app: medical knowledge (61.2%), symptom tracking/management (49.1%), and medication reminders (44.8%). Further, 62.1% wanted access to child's medical record and 58.6% wanted communication with medical providers. Lower education was significantly associated with experiencing phone/plan barriers (P = 0.008).

CONCLUSION

The majority of caregivers of children with cancer use mobile technology with minimal barriers; future research should focus on designing an mHealth tool to address the medical management needs by caregivers of children with cancer.

Practically convenient and industrially-aligned methods for iridium-catalysed hydrogen isotope exchange processes

The use of alternative solvents in the iridium-catalysed hydrogen isotope exchange reaction with developing phosphine/NHC Ir(I) complexes has identified reaction media which are more widely applicable and industrially acceptable than the commonly employed chlorinated solvent, dichloromethane. Deuterium incorporation into a variety of substrates has proceeded to deliver high levels of labelling (and regioselectivity) in the presence of low catalyst loadings and over short reaction times. The preparative outputs have been complemented by DFT studies to explore ligand orientation, as well as solvent and substrate binding energies within the catalyst system.
