This rapid response summarizes the most relevant and recent literature on two PSPs: interventions to support safe care transitions and continuation of anticoagulants post-discharge (PSP 1), and anticoagulation management services in ambulatory settings (PSP 2). Both had been covered in the 2020 MHS III report (which only included literature before 2019), and this report summarizes more recent literature (published in 2019 or later).
