Objective To identify the patient-selected goals for Parkinson’s disease (PD) patients undergoing bilateral subthalamic deep brain stimulation (STN-DBS) and examine the relationship among goal achievement score, DBS clinical outcome measures, and overall patient satisfaction.

Background Despite significant improvement after surgery, a substantial disparity between expectations and actual improvement exists. Failure to achieve patient expectations after DBS could result in overall dissatisfaction despite good clinical outcomes. Therefore, patients’ subjective outcome measures should be considered when evaluating treatment success.

Design/Methods

Seventy-five PD patients undergoing STN-DBS were asked to list three patient-selected goals before and six months after surgery. In the same post-operative survey, patients were asked to rate the degree of achievement for each goal and the overall satisfaction of surgery. DBS clinical outcome was measured using UPDRS scores, MMSE, and Hoehn-Yahr scale at baseline and six months after surgery.

Results

The three most frequently selected goals were “dyskinesia” (52 of 75; weighted N=119), “gait disorder” (47 of 75; weighted N=101), and “medication off duration” (37 of 75; weighted N=79). The overall patient satisfaction was high with 74.7% of patients reporting that they were either very much or much better after surgery. A strong correlation exists between patient satisfaction and patient-selected goal achievement (r=0.640; p<0.001). However, degree of improvement in UPDRS motor scores from pre-DBS to post-DBS does not correlate with patient satisfaction (r=0.100; p=0.395).

Conclusions Although goal achievement scores significantly correlated with patient satisfaction after DBS surgery, clinical outcome measures, such as UPDRS III, did not. Improvement in clinical outcomes alone does not necessarily lead to patient satisfaction. Therefore, assessing patient-selected goals and achievement is important in predicting satisfaction in Parkinson’s disease patients undergoing bilateral STN-DBS.
