The study explored the current status of key competencies and emergency response capabilities among China's Internet "sharing sisters." It was implemented in July 2025 in six hospitals of Shandong province and 1,011 nurses participated. The results showed a high level of basic competencies and skills in emergency situations, with a strong positive correlation between the two domains (r = 0.852; p < 0.001). Key factors influencing competency included hospital level, management support, team therapy support, family support, nurse personality, subjective willingness, training experience, and emergency skills. The authors recommend that healthcare facilities provide standardized training and encourage nurses' willingness to work as "sharing nurses." This approach is intended to ensure the quality and safety of nursing care in the home environment and to optimize the "internet + nursing service" model in primary care.
