You make sure the data those tools collect is correct, accessible, and protected.

This is a broad occupation. Some days you'll feel like a detective, other days like a translator, and some days like a librarian with a strong opinion about metadata. But the core responsibility is consistent: you manage the information that healthcare runs on. That means the patient's medical history, the lab results, the medications they're on, the allergies they have, the insurance codes that determine how the hospital gets paid. If that information is wrong, slow, or lost, the consequences are not a frozen spreadsheet on a screen - they're a delayed surgery, a dangerous drug interaction, or a bill that breaks a patient's finances.
