The cognitive test, critical action checklist, and self-efficacy/confidence surveys were identical for both pre- and post-intervention evaluations. A Wilcoxon rank-sum test was used to evaluate differences in scores between pre- and post-intervention groups. Results Twenty-two emergency medicine residents participated in the study. We observed an increase in median self-efficacy scores (4.0 [4.0-5.0], p ≤ 0.0001), multiple-choice GRIEV_ING scores (90.0 [80.0-90.0], p ≤ 0.0001) and performance scores for death notification (48.5 [47.0-53.0], p = 0.0303). Discussion The RCDP approach was found to be an effective method to train emergency medicine residents in the delivery of the GRIEV_ING death notification curriculum. This approach is actionable with few resources except for content experts trained in RCDP methodology and the application of the GRIEV_ING mnemonic.The regulation of the phosphorylation of mitogen activated protein kinases (MAPKs) is essential for cellular processes such as proliferation, differentiation, survival and death. Mutations within the MAPK signaling cascades are implicated in diseases such as cancer, neurodegenerative disorders, arthritis, obesity and diabetes. MAPK phosphorylation is controlled by an intricate balance between MAPK kinases (enzymes that add phosphate groups) and MAPK phosphatases (MKPs) (enzymes that remove phosphate groups). MKPs are complex negative regulators of the MAPK pathway that control the amplitude and spatiotemporal regulation of MAPKs. MK-STYX (MAPK phosphoserine/threonine/tyrosine-binding protein) is a member of the MKP subfamily, which lacks the critical histidine and nucleophilic cysteine residues in the active site required for catalysis. MK-STYX does not influence the phosphorylation status of MAPK, but even so it adds to the complexity of
