The objectives of this quality improvement (QI) project were to evaluate the effect of a DBS ºÃÉ«ÏÈÉú-Based Intervention (DBS-EBI) on DBS knowledge acquisition among adult patients with PD or ET and their caregivers. Specific aims were to 1) compare changes in DBS knowledge scores before and after delivery of a DBS-EBI and 2) describe satisfaction levels among patients and caregivers with DBS-EBI.

A single group design with three time-points was used to examine knowledge and satisfaction after DBS-EBI in patients with PD and/or ET and caregivers. Knowledge was measured using the Knowledge Evaluation Form before (T1), immediately after (T2), and two weeks after (T3) . also The Evaluation Forms to measure satisfaction (T3).

Patients (n=7 PD; 2 ET; 1 PD + ET, 58.8 ± 17.28 years) had a significant change in knowledge (χ2 df=2, 13.2, p = 0.001), with scores at T2 > T1 (p = 0.007) and T3 > T2 (p = .01).

Caregivers (n = 12; 58.0 ± 15.33 years) also had significant change over the three time-points (χ2df=2, = 10.82, p = .004) with scores at T3 > T2 > T1 (p = 0.05). Patients found the DBS-EBI was helpful (33%), educational (33%), and had good information (33%). Caregivers thought the most important information were related to precautions to minimize infection risks (50%). participants (60%) had positive comments on the DBS-EBI material. 

The DBS-EBI showed a significant increase in knowledge and the majority of participants were satisfied with the content. A DBS-EBI program can improve DBS knowledge, and be a useful practice across DBS centers.
