Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Absolute Change in the Proportion of Subjects Diagnosed With SND Before and After Intervention	The absolute change in the proportion of subjects diagnosed with SND before and after intervention	Up to 1 year post enrollment
Primary	The Absolute Change in the Proportion of Subjects Receiving Indicated Therapy Before and After Intervention	Outcome measure applies to subjects that receive a SND diagnosis	Up to 6 months post diagnosis
Secondary	The Proportion of Phase I Subjects Diagnosed With SND and the Number of Diagnoses That Result in Indicated Therapy	Enrolled subjects only with an SND diagnosis were reassessed at 6 and 12 months post enrollment were reassessed for IPG therapy.	SND diagnosis assessed at 6 and 12 months of follow-up from enrollment until resulting IPG therapy
Secondary	Change in Time to Diagnosis of SND Before and After Intervention	Time to diagnosis days (date of diagnosis - date of enrollment)	From date of enrollment until date of SND diagnosis, assessed up to 60 months
Secondary	Change in Time to Receiving an Indicated IPG Device for Subjects Diagnosed With SND Before and After Intervention	Time to implant in days (date of implant - date of diagnosis)	From date of SND diagnosis until date of therapy, assessed up to 6 months
Secondary	Difference in QoL Between Implant Visit and 6 Months Post-implant	The difference in quality of life was assessed using the SF-12 survey, with higher numbers indicating a better quality of life for the patient. The possible physical score ranges are between 24.0 and 56.6. The possible mental score ranges are between 19.1 and 60.8. Only the difference over time was reported.	between implant visit and 6 months post-implant
Secondary	Change in Zarit Quality of Life (QOL) Between Implant Visit and 6 Months Post-implant	The difference in caregiver burden was assessed using a Zarit survey, with lower numbers indicating a decreased burden or a better outcome for the caregiver. The possible range of scores was between 0 and 88. Only the difference in scores over time were reported.	between implant visit and 6 months post-implant
