ABSTRACT
OBJECTIVES: To establish statewide consensus priorities for safer in-person school for children with medical complexity (CMC) during the coronavirus disease 2019 (COVID-19) pandemic using a rapid, replicable, and transparent priority-setting method. METHODS: We adapted the Child Health and Nutrition Research Initiative Method, which allows for crowdsourcing ideas from diverse stakeholders and engages technical experts in prioritizing these ideas using predefined scoring criteria. Crowdsourcing surveys solicited ideas from CMC families, school staff, clinicians and administrators through statewide distribution groups/listservs using the prompt: "It is safe for children with complex health issues and those around them (families, teachers, classmates, etc.) to go to school in-person during the COVID-19 pandemic if/when " Ideas were aggregated and synthesized into a unique list of candidate priorities. Thirty-four experts then scored each candidate priority against 5 criteria (equity, impact on COVID-19, practicality, sustainability, and cost) using a 5-point Likert scale. Scores were weighted and predefined thresholds applied to identify consensus priorities. RESULTS: From May to June 2021, 460 stakeholders contributed 1166 ideas resulting in 87 candidate priorities. After applying weighted expert scores, 10 consensus CMC-specific priorities exceeded predetermined thresholds. These priorities centered on integrating COVID-19 safety and respiratory action planning into individualized education plans, educating school communities about CMC's unique COVID-19 risks, using medical equipment safely, maintaining curricular flexibility, ensuring masking and vaccination, assigning seats during transportation, and availability of testing and medical staff at school. CONCLUSIONS: Priorities for CMC, identified by statewide stakeholders, complement and extend existing recommendations. These priorities can guide implementation efforts to support safer in-person education for CMC.

PURPOSE: To quantify the effect of contouring variation on stereotactic radiosurgery plan quality metrics for brain metastases. METHODS AND MATERIALS: Fourteen metastases, each contoured by 8 physicians, formed the basis of this study. A template-based dynamic conformal 5-arc dose distribution was developed for each of the 112 contours, and each dose distribution was applied to the 7 other contours in each patient set. Radiation Therapy Oncology Group (RTOG) plan quality metrics and the Paddick conformity index were calculated for each of the 896 combinations of dose distributions and contours. RESULTS: The ratio of largest to smallest contour volume for each metastasis varied from 1.25 to 4.47, with a median value of 1.68 (n=8). The median absolute difference in RTOG conformity index between the value for the reference contour and the values for the alternative contours was 0.35. The variation of the range of conformity index for all contours for a given tumor varied with the tumor size. CONCLUSIONS: The high degree of interobserver contouring variation strongly suggests that peer review or consultation should be adopted to standardize tumor volume prescription. Observer confidence was not reflected in contouring consistency. The impact of contouring variability on plan quality metrics, used as criteria for clinical trial protocol compliance, was such that the category of compliance was robust to interobserver effects only 70% of the time.

A database of clinically approved stereotactic radiosurgery treatment plans was created. One hundred and seventy targets in the database were then retrospectively evaluated using conformity indices suggested by RTOG, SALT-Lomax and Paddick. Relationships between the three alternative conformity indices were determined. The Paddick index combines the information provided by the RTOG and SALT-Lomax indices into a single index. The variation in the geometric overlap ratio, which is related to the SALT-Lomax index, was found to be not clinically relevant for our cohort of patients, and thus the Paddick and RTOG indices can be directly related. It was found that access to a dose volume histogram or dose distribution for a treatment plan renders the RTOG conformity index sufficient for plan quality evaluation.
