Preoperative Counseling in Spinal Cord Stimulation: A Designated Driver in Implantable Pulse Generator-Related...

Spinal cord stimulation (SCS) has been reported to cause substantial pain relief and improved quality of life (QoL) in patients with persistent spinal pain syndrome (PSPS). Despite implantable pulse generator (IPG)-related inconveniences such as pain, shame, and discomfort affecting QoL and patient satisfaction, these are often neglected. Hence, the current study aims to determine the associations between patient satisfaction, IPG-related inconveniences, and preoperative counseling in a homogeneous group of patients with PSPS receiving SCS with IPG implantation in the gluteal or abdominal area.

Retrospective data on sample characteristics were gathered from the EPIC (electronic health record software) digital patient data base. Prospective data on patient satisfaction were obtained with a questionnaire that covered various topics such as shame, pain, disturbances in daily/intense activities, night rest and/or sleep, discomfort caused by clothing, and preoperative counseling. The exact location of the IPG and its scar were determined with photo analysis. Thereafter, the site of IPG placement was classified into separate quadrants within the gluteal and abdominal area. Patient satisfaction was defined as accepting the current location of the IPG without having the wish to undergo revision surgery.

In total, 81 participants (50.9 ± 10 years) were included in this analysis, with patient satisfaction observed in 61 patients (75.3%). Among satisfied patients, more extensive preoperative counseling concerning IPG pain and discomfort was reported compared with patients who were not satisfied (p < 0.001). When comparing the two groups, significant differences were found in shame (8/81, 9.9%), IPG site pain (21/81, 25.9%), disturbance of activities (42/81, 51.9%), and clothing-related discomfort (42/81, 51.9%).

On the basis of the current results, shared decision-making and comprehensive preoperative provision of information are recommended to optimize patient satisfaction regarding IPG pain, discomfort, and inconveniences. Although many patients experience these disadvantages despite successful SCS for pain related to PSPS, most of them accept this if they have received adequate preoperative information about expectations.
