About this study
This prospective, randomized interventional study aims to evaluate the effectiveness of a smart bed-exit alert system for patients undergoing cataract surgery during the preoperative waiting period. Participants will be randomly assigned to either the smart bed-exit alert system group or the standard care group. The study will compare nurse bedside visit frequency and nursing care time during the preoperative waiting period to evaluate whether the smart bed-exit alert system improves patient safety and nursing care efficiency.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Smart Bed-Exit Alert SystemDevice
Participants assigned to the intervention group will receive standard nursing care supplemented by the smart bed-exit alert system. The pressure-sensing mattress continuously monitors patient position and generates real-time alerts when predefined bed-exit criteria are met, allowing nurses to provide timely assistance.
| Study group | Role | What they receive |
|---|---|---|
| Smart Bed-Exit Alert System | Experimental | Participants will receive standard nursing care with the UNEO smart bed-exit alert system during the preoperative waiting period. Receives: Device: Smart Bed-Exit Alert System |
| Standard Nursing Care | No intervention | Participants will receive routine preoperative nursing care without the UNEO smart bed-exit alert system during the preoperative waiting period. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Frequency of nurse bedside visits
Number of nurse bedside visits during the preoperative waiting period.
Measured: During the preoperative waiting period before entering the operating room (approximately 30-60 minutes).
Nursing care time
Total nursing care time provided during the preoperative waiting period.
Measured: During the preoperative waiting period before entering the operating room.
