Dr. Lorna Breen Health Care Provider Protection Act This bill establishes grants and requires other activities to improve mental and behavioral health among health care providers. Specifically, the Department of Health and Human Services (HHS) must award grants to hospitals, medical professional associations, and other health care entities for programs to promote mental health and resiliency among health care providers. In addition, HHS may award grants for relevant mental and behavioral health training for health care students, residents, or professionals. Additionally, HHS must conduct a campaign to (1) encourage health care providers to seek support and treatment for mental and behavioral health concerns, and (2) disseminate best practices to prevent suicide and improve mental health and resiliency among health care providers. HHS must also study and develop policy recommendations on improving mental and behavioral health among health care providers, removing barriers to accessing care and treatment, and identifying strategies to promote resiliency. Furthermore, the Government Accountability Office must report on the extent to which relevant federal grant programs address the prevalence and severity of mental health conditions and substance use disorders among health care providers.
