UC Davis Health has a "Blackout Flag" policy (1190) that is used in trauma care settings to restrict visitors from the patient. The policy's intended goal is to protect patients from potential harmful visitors, especially in ongoing investigations. This policy may impair history taking and well-informed treatments because it restricts knowledge provided by visitors and loved ones. Often placed by police, this policy may be disproportionally applied to patients from marginalized backgrounds and may perpetuate medical distrust.
