Outcome Measures

Primary Outcomes (1)

  • Assess Change in Clinical Opiate Withdrawal Scale (COWS) Score

    The Clinical Opiate Withdrawal Scale (COWS) is an 11-item scale designed to be administered by a clinician. This tool can be used in both inpatient and outpatient settings to reproducibly rate common signs and symptoms of opiate withdrawal and monitor these symptoms over time. The summed score for the complete scale can be used to help clinicians determine the stage or severity of opiate withdrawal and assess the level of physical dependence on opioids. Score Range: The COWS score can range from 0 to 48. Interpretation: 0-4: No withdrawal 5-12: Mild withdrawal 13-24: Moderate withdrawal 25-36: Moderately severe withdrawal 37-48: Severe withdrawal High scores mean more severe withdrawal.

    prior to device placement (0 min), 30 min, 60 min, 120 min, 2nd day, 3rd day, 4th day and 5th day of continuous device use

Secondary Outcomes (1)

  • Assess Change in Subjective Opiate Withdrawal Scale (SOWS) Score

    prior to device placement (0 min), 30 min, 60 min, 120 min, 2nd day, 3rd day, 4th day and 5th day of continuous device use

Study Arms (2)

Bridge™ active device

ACTIVE COMPARATOR

The active Bridge device delivers electrical stimulation to the cranial and occipital nerves.

Device: Bridge™ active device

Bridge™ sham device

SHAM COMPARATOR

The sham device has the same appearance and will require the same placement technique as the Bridge (active) device but will not deliver electrical impulses

Device: Bridge™ sham device

Interventions

Bridge is a percutaneous nerve field stimulation device

Bridge™ active device

The sham device has the same appearance and will require the same placement technique as the Bridge (active) device but will not deliver electrical impulses.

Limitations and Caveats

The study was terminated prematurely due to sponsor decision with no clinical rationale for termination. This prospective study investigated a test device deemed "end-of-life" by the manufacturer. Only 13 subjects used devices of 48 anticipated; 6 subjects completed the study (3 with active device, 3 with shame device). We reported all demographic data and outcome measure data from the limited sample size. Further data reporting would be statistically inappropriate due to the sample size.
