    • Physician disclosure of adverse events: to patients and institutions

    • Financial burden for patients: institutions should ensure patients are not burdened financially

    • Root cause analysis: Conduct a root cause analysis of the adverse event and develop an action plan

    • Apology: If an error occured, the institution should offer an apology

    • Technology transition policies:

    • Communication: The key to improving patient safety is transparent communication
