562 Background: Under the NCI ASCO Teams Project, we proposed a 4R Model which enables patient (pt) and care team to manage timing and sequencing of interdependent care with a novel multimodality 4R Care Project Plan (Trosman JOP ’16). 4R (Right Info/Care/Patient/Time) was previously piloted at 3 Chicago centers (Weldon ASCO ‘18). Methods: A new study tested impact of 4R on timing and sequencing of guideline recommended care at 4 safety net and 3 non safety net US centers. 4R Plans were provided to stage 0-III breast cancer pts Jan-Nov’18, 4R cohort. Clinical and pt reported data analyses compared 4R cohort (N=105) to a historical control cohort of pts who received care pre-4R, Jan - Dec ’17 (N=190). Results: We significantly improved 3 referral metrics and 4 referral completion metrics - receipt of care by pts who were referred (Table). After referrals, safety net pts had a significant increase in 4R vs control cohort in receiving genetic consult (72%, 21/29 vs. 42%, 18/43, p=.02) and dental visit (100%, 6/6 vs. 20%, 1/5, p=.02). They had lower increases in flu shot referrals (41%, 24/58, vs 36%, 37/104, NS) and dental referrals (10%, 6/58, vs 5%, 5/104, NS) than non safety net pts who had significant increases. Other metrics improved at a similar rate for safety net and non safety net pts. Conclusions: 4R markedly improved referral and receipt of interdependent guideline recommended breast cancer care. For most metrics safety net pts benefited from 4R at a similar or higher rate than non safety net pts, indicating that 4R may reduce care disparities. Low increases in referrals for safety net pts and in trial referral/enrollment for all pts must be addressed. An expansion of 4R across the US continues this work. [Table: see text]
