4r Care Delivery Program Results: Impact Of Implementation Metrics On Patient Self-Management And 4r Usefulness.

e14039 Background: We previously proposed a 4R care delivery model that facilitates teamwork and patient self-management (pSM) in cancer care (NCI ASCO Teams Project, Trosman JOP 2016). 4R (Right Info / Care / Patient / Time) enables patient and care team to manage complex care with an innovative 4R Care Sequence. We tested 4R at 10 US sites in a stepwise mode 2016-2019. Methods: Step 1 included 1 academic and 2 nonacademic sites; step 2 included 3 academic and 4 nonacademic sites. Patients with stage 0-III breast cancer received 4R Sequences (4R Cohort). We surveyed 4R and historical control cohorts of patients treated at the same sites pre-4R. We assessed the impact of implementation metrics on usefulness of 4R to the 4R cohort and on improvement of pSM in 4R cohort vs historical control cohort. Results: Survey response rates: 63%, 422/670 (4R cohort); 47%, 466/992 (control cohort). Three of the five implementation metrics significantly impacted patient usefulness of 4R (Table). Patients at step 2 sites; sites with a systematic care process; and sites with small practices reported significantly higher 4R usefulness than patients in the comparison subgroup within respective metrics. 4R usefulness was not affected by practice setting or availability of patient navigators. pSM was significantly improved between control and 4R cohorts along all implementation metrics (p < .001), but the magnitude of incremental improvement between comparison subgroups varied across metrics (Table), with the largest increment associated with the program step metric. Conclusions: 4R is useful to patients across settings, with or without patient navigators. Stepwise design is effective in increasing 4R impact overtime. Future 4R Program will investigate an expanded array of implementation metrics and their influence on 4R outcomes. [Table: see text]
