      Medtronic is sponsoring a quality improvement study called Brady MX. It is hypothesized that&#xD;
      lack of awareness of treatment and diagnostics pathways result in lower number of referrals&#xD;
      to implanters of IPG.&#xD;

    <description>Because the study intervention was not conducted, it is not possible to compare the proportion of subjects with an SND diagnosis pre-intervention (Phase I) to the proportion post-intervention (Phase II).

    <description>The change between subjects referred to an indicated IPG will be measured after the intervention in total number of patients that are referred correctly.&#xD;
Because the study intervention was not conducted, it is not possible to compare the proportion of subjects receiving therapy referral for an indicated IPG pre-intervention (Phase I) to the proportion post-intervention (Phase II). Instead, the proportion of SND subjects receiving a referral for an indicated IPG device in Phase I are reported.</description>

has dmc: No
Medtronic is sponsoring a quality improvement study called Brady MX. It is hypothesized that
      lack of awareness of treatment and diagnostics pathways result in lower number of referrals
      to implanters of IPG.
observational model: Cohort
time perspective: Prospective
measure: Absolute Change in the Proportion of Subjects Diagnosed With SND at Pre Specific Time.
time frame: 6 and 12 months
description: Because the study intervention was not conducted, it is not possible to compare the proportion of subjects with an SND diagnosis pre-intervention (Phase I) to the proportion post-intervention (Phase II). Instead, the proportion of subjects with an SND diagnosis in Phase I are reported
measure: Number of SND Subjects Receiving a Referral for an Indicated IPG Device After the Intervention
time frame: 3, 6, and 15 months
description: The change between subjects referred to an indicated IPG will be measured after the intervention in total number of patients that are referred correctly.
