A new mechanical compression device (MCD) significantly improved wear time and patient comfort for venous thromboembolism (VTE) prevention compared to intermittent pneumatic compression (IPC) devices. Nurses also reported improved documentation accuracy, suggesting MCDs are a promising alternative for VTE prophylaxis.
Area of Science:
- Medical Devices
- Clinical Quality Improvement
- Vascular Medicine
Background:
- Venous thromboembolism (VTE) is a major cause of preventable hospital deaths.
- Current intermittent pneumatic compression (IPC) devices have challenges leading to subtherapeutic use.
- A novel mechanical compression device (MCD) was compared to standard IPC for VTE prevention.
Purpose of the Study:
- To compare the novel MCD with standard IPC devices on three hospital units.
- To evaluate patient outcomes including wear time, comfort, satisfaction, and mobility.
- To assess nurses' satisfaction with clinical usability and mobility documentation.
Main Methods:
- A pre-post study design was employed with 89 surgical patients and 63 nursing staff.
- Data collected via electronic health records, device records, and patient/nurse surveys.
- Statistical analysis included descriptive statistics and independent sample t tests.
Main Results:
- MCD use resulted in significantly longer wear time (19.3 hours/day) versus IPC (12.9 hours/day).
- MCD patients reported better sleep, fewer leg issues, and improved mobility assistance.
- Nurses noted improved mobility documentation accuracy with MCDs.
Conclusions:
- The MCD shows promise for VTE prophylaxis, improving patient and nurse experiences.
- Actual and perceived benefits were observed from both patient and nursing perspectives.
- Further research is recommended to validate these initial findings.
