Sistema Inteligente de Alerta de Salida de Cama para una Mayor Seguridad del Paciente en Cirugía de Cataratas

Patients undergoing cataract surgery remain on a stretcher in the operating room holding area for approximately 30-60 minutes while awaiting adequate pupil dilation. During this period, patients may attempt to leave the bed because of physiological needs (e.g., toileting) or psychological factors (e.g., anxiety or seeking family members), increasing the risk of falls and compromising patient safety. This prospective, randomized interventional study will enroll 160 adult cataract surgery patients. Participants will be randomly assigned in a 1:1 ratio to either the intervention group (smart bed-exit alert system) or the control group (standard nursing care). The intervention group will be monitored using the UNEO smart bed-exit alert system, which consists of a pressure-sensing mattress capable of detecting body position and bed-exit attempts. When a predefined bed-exit threshold is reached, the system immediately notifies nursing staff through audible and tablet alerts. The control group will receive routine nursing observation according to standard clinical practice. The study will compare patient care requests, attempted bed exits, nurse bedside visit frequency, and direct nursing care time between the two groups to evaluate whether the smart bed-exit alert system improves nursing workflow and enhances patient safety.
