Rechargeable occipital nerve stimulator systems: a patient satisfaction study

Area of Science:

• Neurology
• Neurosurgery
• Pain Management

Background:

• Cluster headache is a severe, disabling neurological condition affecting 0.12% of the population.
• Occipital nerve stimulation (ONS) with an implantable pulse generator (IPG) is a treatment for intractable cluster headaches.
• Rechargeable batteries offer a longer lifespan compared to non-rechargeable ones for ONS devices.

Purpose of the Study:

• To assess patient satisfaction with rechargeable batteries used in ONS for cluster headache treatment.
• To determine the convenience and perceived benefits of rechargeable ONS systems.
• To compare patient preference for rechargeable versus non-rechargeable batteries.

Main Methods:

• A survey was conducted with 100 patients who received ONS with rechargeable systems at a London hospital.
• Patient satisfaction was evaluated using a questionnaire adapted for rechargeable IPGs.
• Ninety-two patients participated, with some having prior experience with non-rechargeable batteries.

Main Results:

• 74% of patients found recharging the battery convenient.
• 88% felt the inconvenience of recharging was outweighed by the stimulation benefits.
• 84% of patients who previously used non-rechargeable batteries preferred the current rechargeable system.

Conclusions:

• ONS with a rechargeable battery system demonstrates positive patient outcomes.
• The high patient compliance and sample size provide a reliable estimation of effectiveness.
• Rechargeable IPGs for ONS may be the preferred system for patients undergoing this treatment.
