11005 Background: Despite progress in the enrollment of underrepresented in medicine (UIM) individuals in medical schools, hematology/oncology (HO) remains one of the least diverse medical subspecialties. We evaluated current recruitment efforts and barriers to the inclusion of UIM individuals in HO fellowship programs. Methods: We conducted a national online survey of program directors (PDs) and associate PDs (reported in aggregate as PDs) of adult and pediatric HO fellowships. Each PD received a unique survey link via email and 4 email reminders over the 8-week study period. Interim results at 4-weeks are presented and summarized with descriptive statistics. Results: At a pre-defined interim time point of 4 weeks, 78 HO PDs participated (18% response rate) and 69 completed the survey (88% completion rate). Most self-identified as women (57%, n = 38) and White (55%, n = 37), were affiliated with an academic program (79%, n = 53), and led an adult HO fellowship (73%, n = 49). Most PDs reported under or no representation of UIM faculty in their divisions; 9% (n = 6) self-identified as UIM. PDs reported their HO fellowships matched a median of 3 UIM fellows over the last 5 years (IQR 2-5 over 5 years); 46% (n = 32) reported UIM recruitment was unchanged and 4% (n = 3) decreased during this period. About half of PDs (51%, n = 35), matched a UIM candidate in the 2023 match. Of the 21% (n = 14) of PDs whose programs had no UIM fellows, 0% matched a UIM applicant in the 2023 match. 52% (n = 36) of PDs endorsed an inability to match UIM applicants despite consistently ranking them highly. PDs perceive the top 3 barriers to UIM recruitment as: low number of UIM applicants (53%, n = 41), geographic program location (50%, n = 39), and lack of diverse faculty/fellows in their program (42%, n = 31). 10% (n = 7) also reported meeting resistance about DEI initiatives. While 53% (n = 41) of PDs believe fellow demographics should reflect the local population, 23% (n = 16) don’t know how to increase diversity and 11% (n = 8) do not believe their program’s diversity needs to increase. In answers to open ended questions, some PDs expressed disagreement with the definition of UIM and reported a perceived limited number of qualified UIM applicants. Almost all institutions provide DEI training (96%, n = 72) for faculty and most PDs believe it has improved recruitment and inclusion of diverse individuals (52% and 65%, respectively). Yet, 34% (n = 23) agree that UIM fellows in their program are treated differently because of their race/ethnicity and 22% (n = 15) agree that UIM fellows repress their identity or background to be respected by faculty, peers, and staff. Conclusions: Historically and currently excluded populations remain underrepresented in the HO workforce. PDs face multiple barriers to the recruitment of diverse fellows, including differing views on the definition of UIM and perception of the value of diversity in the physician workforce.

1533 Background: FDA-approved chimeric antigen receptor T-cell (CAR-T) and bispecific T cell engager (TCE) therapy are most commonly managed inpatient. Here we report our experience with hospital-based outpatient (HBO) management of patients (pts) receiving FDA-approved CAR-T or TCE and a predictive model for increased risk of early hospitalization (≤3 days post CAR-T). Methods: We reviewed the outcomes of pts who received FDA-approved CAR-T (axi-cel, brexu-cel, ide-cel, cilta-cel) or TCE (teclistamab) in the HBO unit between 3/2021 and 1/2023 at Mayo Clinic, Rochester. Results: HBO is closely integrated with inpatient practice and includes the same specialty trained clinical team. It is the first point of contact 24/7 for pts and triage evaluations. CAR-T and TCE are given on HBO followed by monitoring per REMS and as clinically needed until admission criteria is met. Remote patient monitoring (RPM) tools were used as part of outpatient monitoring. Out of 169 CAR-T pts, 87 (51%) were dosed with new indication/products (follicular lymphoma, mantle cell lymphoma, myeloma). Among those, 80 (92%) pts were dosed outpatient, among whom 21 (27%) were never hospitalized. CRS and ICANS incidences were comparable to that reported in registration studies. Median time to first admission from CAR-T infusion was 1 day (range, 0-9), with 31% (n=18/59) of admissions after day 3 post infusion. The most common cause of hospitalization was fever (n=40, 59%). Median length of hospital stay was 4 days (range, 1-49). Median time to tocilizumab (n=45, 80%), steroid (n=1, 2%), escalation of oxygen support (n=7, 12%), vasopressor (n=2, 3%), ventilator (n=1, 2%), hemodialysis (n=1, 2%) and ICU transfer (n=3, 5%) was 1 day (range, 0-31) after first admission. Use of bridging therapy, elevated CRP and LDH were predictive of early admission (ROC AUC 0.62). Four pts received teclistamab on HBO and enrolled in RPM. Data from more pts will be reported at ASCO. Conclusions: Our expanded study in CAR-T and TCE confirms that HBO is feasible and that CAR-T and TCE can be safely dosed outpatient. Approximately 31% of pts were admitted after 3 days from CAR-T infusion, and 27% of our pts were never admitted. Variables associated with aggressive disease can predict early hospitalization in pts receiving FDA-approved CAR-T. Extension of HBO practice to TCE is feasible.[Table: see text]
