Description

Technical Field

[0001] This invention relates to the field of computer technology, and specifically to a suicide risk early warning method and system based on hospitalized patients. Background Technology

[0002] Suicide is a major public health problem worldwide. Hospitalized patients frequently commit suicide, with a suicide rate 4-5 times higher than the general population. As the primary treatment center for various patients, healthcare institutions face the critical challenge of identifying and preventing suicide risks. Traditional methods for assessing patient suicide risk rely heavily on the clinical experience and subjective judgment of healthcare professionals, leading to problems such as untimely, inaccurate, and incomplete assessments, making it difficult to effectively and accurately identify high-risk patients. Furthermore, the lack of systematic and standardized prevention and intervention measures results in poor intervention outcomes. Although suicide is a low-probability event, its consequences are severe. Suicide can lead to disability or even death, causing immense distress to patients' families and healthcare workers, and may even trigger serious medical disputes.
