232 Background: Traditionally, hospital units function as multidisciplinary teams which work in silos and communicate via notes in the Electronic Health System. This often leads to communication breakdown, frequently translating to adverse clinical outcomes and prolonged hospital length of stay. Our primary objective was to introduce Inter-Professional Team (IPT) rounds on the oncology unit and evaluate the impact on length of stay (LOS) within a Plan, Do, Study, Act (PDSA) cycle. Methods: The care transition team planned the IPT rounds structure and training curriculum which included team goals, post-rounds structure for addressing barriers to care progression, and member roles/scripting. Change in LOS and case mix index (CMI)-adjusted LOS post-IPT round implementation ( Do) in July 2017 was analyzed ( Study) using hierarchical linear models for patients with an admission to the oncology service from September 2016 to March 2018. Beta coefficients (β) and 95% confidence intervals (CI) were estimated and models were adjusted for calendar time. Results: Ten attending medical oncologists participated in IPT round implementation. Of 889 oncology admissions, median LOS and CMI-adjusted LOS pre-IPT round implementation (n = 464) was 4 days (IQR 2-6) and 3 days (IQR 1.8-4.7), while post-IPT round implementation (n = 425) was 4 days (IQR 2-6) and 2.9 days (IQR 1.9-4.4), respectively. Three common reasons for admission were septicemia (n = 96), hematologic complications (n = 42, e.g. anemia/neutropenia), and renal failure (n = 25). Adjusted models for LOS and CMI-adjusted LOS showed no significant difference post-IPT round implementation (β = 0.8 days, 95% CI -0.7-2.3; β = 0.5 days, 95% CI -0.3-1.3, respectively) when compared to pre-implementation. Conclusions: We did not observe decreased LOS in early outcomes. However, IDT rounds built on TEAMSTEPPS 2.0 elements with incorporation of key principles desirable in a patient care team. Next steps include further analysis to better understand cancer stages and diagnoses contributing to longer LOS. We also plan to evaluate patient satisfaction, educational needs, and readmission rates to restructure ( Act) IPT rounds to better serve the needs of our unique patient population.
