Bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) is an effective and proven treatment option for patients with advanced Parkinson's disease (PD). Long-term outcomes (>5 years) have demonstrated sustained improvement in objective motor symptoms; however, few studies have evaluated patient-centered outcomes other than quality of life (QOL). A locally developed DBS-patient-centered outcomes questionnaire was administered to PD patients >5 years post-DBS. All questions were scored on a ten-point scale, whereby 0 represented the most 'positive' answer and 10 the most 'negative' answer. Pre-operative scales were repeated at the time of survey. Fifty-two patients (mean 8.2 ± 2.6 years post-DBS) were included. Satisfaction was high with median score (range) of 1/10 (0-8) at the time of survey. Patients endorsed having made the correct decision by undergoing DBS, with a score of 0 (0-10), would choose to have DBS again, with a score of 0 (0-10), and would recommend DBS to others, with a score of 0 (0-10). Pre-operative expectation target was set at a high level with a score of 2 (0-10). Parkinson's Disease QOL (PDQ-39) Questionnaire Summary Index (SI) scores were, mean (SD), 2.1 (18.2) above baseline (p = 0.44). Those with worsening in PDQ-39-SI scores had less satisfaction with DBS (rs = 0.57, p ≤ 0.0001). This is the first study to assess long-term patient satisfaction with STN DBS. We are currently collecting data prospectively to confirm the results of these preliminary findings.
