Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent software update. Has there been any firmware or software changes to the Platinium 4LV CRT-D devices in the last 1-2 months?

Why it matters: Software updates can inadvertently affect battery performance. Expected answer: Yes, there was a minor firmware update. Impact on approach: If yes, we'd focus on the update's impact on battery management.

• Considering user segments, I'm curious about the distribution of reports. Are these battery depletion issues concentrated in a specific patient demographic or geographic region?

Why it matters: Helps identify if the issue is universal or localized. Expected answer: Reports are evenly distributed across demographics and regions. Impact on approach: If concentrated, we'd investigate environmental or usage pattern factors.

• Regarding performance metrics, has there been any change in how battery life is measured or reported in the past month?

Why it matters: Ensures we're comparing apples to apples in our data analysis. Expected answer: No changes in measurement or reporting methods. Impact on approach: If changed, we'd need to recalibrate our analysis based on the new metrics.

• Thinking about recent product changes, have there been any modifications to the battery itself or the device's power management system?

Why it matters: Direct changes to these components could explain the increased depletion rate. Expected answer: No recent changes to battery or power management. Impact on approach: If yes, we'd focus on these specific changes and their potential impacts.
