Abstract The intracluster correlation coefficient (ICC) measures the correlation of observations within clusters and is a key parameter for power and sample size calculations for cluster randomized trials (CRTs). To facilitate the design of future CRTs within the National Cancer Institute Community Oncology Research Program (NCORP), all studies from the NCORP website were reviewed to identify completed CRTs. ICCs for primary and secondary outcomes (when available) were ascertained from these trials and summarized in this article as a resource for future trial development. Although ICCs are relatively small for many outcome cluster combinations, that is not always the case, so consideration should always be given to the specific outcome of interest, trial design, and type of cluster when estimating an ICC to facilitate trial development.

PURPOSE Routine collection of sexual orientation (SO) and gender identity (GI; collectively SOGI) in cancer clinics advances cancer care equity. METHODS In 2022, NCI Community Oncology Research Program (NCORP) practice groups were asked about routine collection of SOGI data in the electronic health record. The proportions of practice groups reporting collection of SO and/or GI data were calculated, and practice group characteristics were assessed for associations. RESULTS Of 271 practice groups nationwide, 42% (n = 112) collect SO data, 58% (n = 157) collect GI data, and 35% (n = 96) collect both. In multivariate analyses, SO data collection was associated with practice groups having minority outreach staff (odds ratio [OR], 2.07 [95% CI, 1.12 to 3.81]; P = .02); GI data collection was associated with practice groups located in the Northeastern United States (OR, 2.08 [95% CI, 0.73 to 5.91]; P = .045), and those with a higher proportion of new patients who were White (OR, 1.02 [95% CI, 1.01 to 1.04]; P < .001). Practice groups in the South were least likely to collect SOGI data (OR, 0.49 [95% CI, 0.26 to 0.94]; P = .004). There were no statistically significant differences in SO and/or GI collection on the basis of the practice group's proportion of Medicaid/Medicare patients, number of new patients with cancer per year, or practice ownership. CONCLUSION Slightly over one third of NCORP practice groups report routinely collecting SOGI data. There are regional differences in data collection, underscoring the need to craft targeted, region-specific interventions focused on boosting the capture and recording of SOGI data in an affirming manner.

PURPOSE Oncology advanced practice providers (APPs), including nurse practitioners, clinical nurse specialists, physician assistants, and clinical pharmacists, contribute significantly to quality cancer care. Understanding the research-related roles of APPs in the National Cancer Institute's (NCI) Community Oncology Research Program (NCORP) could lead to enhanced protocol development, trial conduct, and accrual. METHODS The 2022 NCORP Landscape Assessment Survey asked two questions about the utilization and roles of APPs in the NCORP. RESULTS A total of 271 practice groups completed the 2022 survey, with a response rate of 90%. Of the 259 nonpediatric exclusive practice groups analyzed in this study, 92% used APPs for clinical care activities and 73% used APPs for research activities. APPs most often provided clinical care for patients enrolled in trials (97%), followed by assistance with coordination (65%), presenting/explaining clinical trials (59%), screening patients (49%), ordering investigational drugs (37%), and consenting participants (24%). Some groups reported APPs as an enrolling investigator (18%) and/or participating in institutional oversight/selection of trials (15%). Only 5% of NCORP sites reported APPs as a site primary investigator for trials, and very few (3%) reported APPs participating in protocol development. CONCLUSION Practice groups report involving APPs in clinical research within the NCORP network; however, opportunities for growth exists. As team-based care has enhanced clinical practice in oncology, this same approach can be used to enhance successful research. Suggested strategies include supporting APP research-related time, recognition, and education. The findings of this survey and subsequent recommendations may be applied to all adult oncology practices that participate in clinical research.

6548 Background: National organizations (ASCO, ACS, ACCR) have advocated for routine collection of sexual orientation and gender identity (SOGI) in cancer clinics to advance cancer health equity. In 2017, only 24% of NCI Community Oncology Research Program (NCORP) practices collected sexual orientation (SO) data, while 10% collected gender identity (GI) data; recent progress in collection is unknown. Methods: In 2022, NCORP practices again completed a Landscape Assessment to assess research capacity (funding support from 2UG1CA189824) and were asked whether they routinely collect SOGI data in the electronic health record (EHR). The proportions of practices reporting collection of SO and/or GI data and population level differences over time were calculated using Fisher’s exact tests. Univariate associations between SOGI data collection and site-related variables were evaluated using logistic regression; significant associations were then tested in separate multivariate logistic regression models. Results: 271 practices responded to the Landscape Assessment; 42% (114) reported that they routinely collect SO data, 58% (157) reported that they collect GI data; both were significantly higher than 2017 (p<0.001). Compared to other regions, practices in Northeastern states were significantly more likely to report collecting GI, but not SO. Practices with higher proportions of White patients were also more likely to collect GI (p < 0.001). Practices with community outreach staff were more likely to collect SO (Table 1). There were no significant differences in SOGI collection by Medicaid/Medicare patients, new cancer cases per year, or practice ownership. In both 2017 and 2022, sites in Southern states were less likely to collect GI than sites in other regions. Conclusions: Progress was made in SOGI collection between 2017 and 2022, but fewer than half of NCORP sites routinely collect SOGI data, in spite of national guidelines. Further examination of the cultural context of SOGI collection could inform efforts to improve data collection in the South and other regions. The lack of data on sexual and gender minority patients in the EHR contributes to health inequity and deficiencies in patient-centric care. [Table: see text]
