Individuals who suffer from mental illness are at an increased risk for suicide. That risk is substantially higher in the post-discharge period from psychiatric hospitalization. Safety planning intervention (SPI) is a common intervention tool that is utilized to mitigate the risk of suicide. Current research notes promising results of SPI use in the emergency department (ED); however, there is limited research regarding SPI use during psychiatric hospitalization on the day of discharge. This paper aims to evaluate current research on the topic and establish a need for more widespread use of SPI during psychiatric hospitalization.
