Patient factors: (1) critically ill patients, patients with rapid changes in their condition, many complications, severe injuries or complicated lesions, patients with difficult and high surgical risks have high nursing risks. (2) Individual differences of patients: For example, patients with high allergic constitution are at risk of allergic reaction when using other drugs. (3) Patients with health problems are prone to cognitive and emotional crisis. If nurses fail to provide effective psychological support in time after the psychological crisis, conflicts between nurses and patients may occur, and even develop into disputes.
Nurse factor: Due to the increasing complexity of patients' diseases and conditions, the legal awareness and self-protection awareness of patients and their families are increasing day by day, and the requirements for hospital service attitude and medical quality are getting higher and higher. In addition, the guidance of the news media and the direct intervention of the judicial department have led to an increase in medical disputes year by year. There are many opportunities for clinical nurses to contact patients directly, and there are also many opportunities for contradictions and disputes. However, nurses did not change their ideas in time, lacked legal knowledge, emphasized treatment, ignored records, and had insufficient writing level of nursing records, which had potential safety hazards.
