Hidden dangers are categorized into 2 levels. Hidden danger grading is based on the difficulty of rectification, treatment and elimination of hidden dangers and their scope of influence, can be divided into general accident hidden danger and major accident hidden danger.
There are four levels according to the severity of the incident (as categorized by the Chinese Hospital Association): warning incident, adverse incident, incident without consequences and hidden incident.
Warning events: unintended death, or permanent loss of function that is not the result of the natural progression of the disease.
Adverse events: damage to a patient's body and function during the course of medical treatment of a disease that is caused by the diagnostic and therapeutic activities rather than the disease itself.
Non-consequential event: the fact that an error occurred, but did not cause any damage to the patient's body and function.
Hidden event: the fact that the error was not formed because it was detected in time.
Adverse nursing events are categorized into 3 levels based on whether the adverse event occurs and the harm it causes in the patient or healthcare worker after it occurs.
Level 1 adverse events: those that have occurred, causing patient death, disability, tissue and organ damage leading to dysfunction, exacerbation of the condition, delayed recovery, or any of the following situations, i.e., valid complaints or disputes arising from negligent nursing behavior; hospital infection outbreaks; incorrect identification of surgical identity sites; surgical instruments left in the body; patient death due to accidents.
Second-degree nursing adverse events: events that have occurred and increased the patient's suffering, but have no effect on the patient's condition and treatment outcome, and the degree of harm to the patient from the event is categorized as no harm, mild harm, moderate harm and severe harm. In addition to the above 10 categories of situations in addition to 8 and 9 categories of situations, other situations that have occurred and involved patients but have not yet reached the first level of nursing adverse events are included in the scope of this level.
Three levels of adverse nursing events: hidden events, which are those in which the adverse event did not actually occur or the event did not involve the patient due to inadvertent or real-time interventions, or those that are not the result of nursing behavior (e.g., public **** facility events, medical equipment device events)
