Summary
A new IV CareLock™ device and protocol prevent patients from self-injecting into vascular access devices (SIVADs). This innovation reduces risks of infection, overdose, and death for at-risk patients.
Area of Science:
- Medical Devices
- Patient Safety
- Infectious Disease Prevention
Background:
- The opioid epidemic presents challenges in managing patients with substance use disorders and psychiatric conditions.
- Patients who self-inject into vascular access devices (SIVADs) face risks including infection, prolonged hospitalization, and overdose.
- The intravenous (IV) CareLock™ device was developed to mitigate SIVAD incidents and prevent patient access to IV lines.
Purpose of the Study:
- To develop and implement a protocol to reduce SIVAD incidents.
- To evaluate the effectiveness of the IV CareLock™ device in preventing SIVAD.
Main Methods:
- A multidisciplinary team conducted a gap analysis and developed a comprehensive protocol.
- The protocol identified at-risk patients for SIVAD.
- The IV CareLock™ device was integrated into clinical practice.
Main Results:
- The multidisciplinary protocol successfully identified patients at risk of SIVAD.
- The IV CareLock™ device, guided by the protocol, prevented SIVAD.
- Providers could continue administering medications via the IV line.
Conclusions:
- The novel IV CareLock™ device and associated protocol enable safe care for at-risk patients.
- This approach significantly reduces the potential for adverse outcomes related to SIVAD.
- Improved patient safety and reduced healthcare complications were achieved.
