Healthcare analytics has never been more sophisticated, yet many improvement efforts still stall. Reports arrive too late. Dashboards lack context. Frontline teams struggle to connect yesterday’s work to tomorrow’s outcomes. The gap is not insight. It is timing, trust, and follow-through. Health Catalyst has a solution.
How Near-Real-Time Data and AI Are Changing Clinical Improvement Work
In a sit down interview with Healthcare IT Today, Holly Rimmasch, Chief Clinical Officer and SVP of Improvement Services at Health Catalyst, and Kathleen Merkley, SVP of Clinical Improvement, unpacked why analytics alone rarely change behavior and how faster feedback, AI-guided prioritization, and clinician ownership are driving healthcare improvement today.
Key Takeaway
- Near-real-time data changes behavior in ways retrospective reporting never can. When clinicians see yesterday’s sepsis case instead of last quarter’s averages, feedback becomes persona and far more likely to drive sustained improvement.
- AI creates value when it removes guesswork, not when it adds complexity. Health Catalyst uses AI to identify which interventions are most likely to move outcomes like length of stay, readmissions, and mortality before teams invest time and effort.
- Sustainable improvement depends on clinician ownership, not top-down mandates. Some of the biggest gains come from frontline clinicians designing solutions they believe in and then seeing the data confirm their impact.
Why Near-Real-Time Analytics Drive Clinical Behavior Change
One of the clearest shifts Health Catalyst has observed is what happens when teams stop waiting weeks or months for reports and instead see performance within a day. Near-real-time data turns improvement from a retrospective exercise into something clinicians can recognize, remember, and act on while cases are still fresh.
As Merkley explained through the lens of sepsis care, speed changes everything.
“If I’m a sepsis coordinator and in a health system, I can look within 24 hours at someone who was in the ED yesterday with sepsis. I can see when their antibiotic was started, when their fluids were started, how much fluid they got, what was their lactate, what was their length of stay.”
She contrasted that with traditional reporting cycles.
“Someone two months later is not going to remember that case like they did the day before.”
Health Catalyst supports this shift by refreshing key clinical data on a 24-hour cadence and structuring dashboards around real clinical workflows. That timing allows multidisciplinary teams to meet regularly, review recent cases together, and keep improvement grounded in lived experience rather than faded memory.
Using AI To Prioritize the Improvements That Actually Move Outcomes
Rather than positioning AI as a replacement for clinical judgment, Health Catalyst uses it to narrow the field. The goal is to identify which actions are most likely to change outcomes before teams invest time and energy.
Merkley shared a concrete example from heart failure care.
“We’re taking all of those identified opportunities and they’re running algorithms on them and saying, if you do this, you will see this rate reduction in length of stay and this improvement in mortality.”
That approach replaces intuition and pet projects with evidence.
“We can go in and say with authority that yes, if you do daily weights every day on your heart failure patients, you’re going to improve their length of stay and their readmission rate. So simple. But AI was able to tell us how important that was.”
Rimmasch added that this kind of prioritization used to require extensive human analysis.
“In past, we’ve always done this improvement work… that was a human intervention that happened. We can now integrate that into AI to say, here’s your opportunity, here are some projections, and here are some things you might want to consider doing.”
The result is less debate over what to tackle first and more confidence that effort is being spent where it matters.
Why Frontline-Led Improvement Outlasts Top-Down Programs
The most consistent theme across the conversation was where durable improvement actually comes from. Not predefined playbooks. Not executive directives. But clinicians who see the data, trust it, and help shape the solution.
Merkley described how her own approach evolved: “I always come in with a list of interventions. Well, you could do this, this, or this. And I used to be hurt because the interventions were never what I suggested.” She quickly put aside that frustration when she realized something important about the frontline teams she was working with: “These clinicians are so thoughtful and so passionate about caring, and they come up with really great ways to improve care. And we institute those and we see big results.”
Rimmasch noted that this ownership appears, even after there is early resistance: “Sometimes we start with people who aren’t really excited to do this. But they see the opportunities.” The key, according to Rimmasch is to show improvement over time: “We understand the importance of sustainability. We can follow a process, an improvement, for years if we need to.”
Health Catalyst’s role is to create the conditions where that ownership can take hold. Standardized metrics, trusted data definitions, and sustained visibility allow teams to track progress and maintain momentum beyond an initial push.
From Analytics to Improvement That Lasts
Throughout this conversation, Rimmasch and Merkley repeated the same themes:
- Timely data that reflects real work
- AI that clarifies priorities instead of complicating them
- Improvement efforts shaped by the people closest to patient care
When those elements come together, analytics stop being a reporting function and start reinforcing a cycle clinicians want to sustain.
As Rimmasch put it, improvement builds on itself.
“You start doing it, you learn about it, and it just starts to swirl and it gets better for patients, for clinicians, for administrators. It gets better for everybody.”
