Detailed Description
This study will employ a single-blind where study participants will not be told about the dose reduction of at least 20% when the valve-gated pump is implanted. A study participant has a significant potential to bias when informed they will get less drug with the new pump than they were receiving in the old pump this could subjectively affect pain scores as well. After valve-gated pump implant and dose reduction, the appropriate pain therapy will be provided to adequately address pain management in the opinion of the study investigator using standard of care processes and VAS scores.
Once subjects have been implanted with the valve-gated pump they will be started on a minimum 20% dose reduction (same medications and concentrations prior to explant). If at any time during the subjects' treatment it is determined by the investigator that the subjects' treatment dose needs to be increased, the dose can be increased in increments not to exceed 5% (no change to concentration) based on VAS scores at current and last visits.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Prometra Programmable Pump
Pain scores and drug doses will be prospectively collected for valve-gated Prometra® Programmable Pump system(Flowonix Medical)' at (refills 1-3) and will be compared to 3 months retrospectively collected pain scores (VAS, ODI and Global Pain Scale Assessments) and drug doses prior to peristaltic pump explant.
|
This valve gated Prometra II Programmable Pump system will be replacing prior peristaltic Synchromed II pump
Other Names:
|
NO_INTERVENTION: Retrospective records for peristaltic pump
Prior pain scores and drug doses from the patients who need a new valve gated pump will be recorded and used for comparison after it is changed.
