3 worthwhile business insights from 1 big data project focused on length of patient stay

The CEO of a data analytics company shares three insights one health system learned from crunching 47,000 patient outcomes and 534,000 variable combinations.

After hearing so much about the promise of big data, it was refreshing to hear about how this “new” strategy works in reality.

During a recent O’Reilly webinar about personalized medicine, Arijit Sengupta of BeyondCore explained how one of the company’s clients — a large healthcare system —  analyzed patient length-of-stay patterns.
The project involved:

  • 247,000 patient outcomes
  • 534,000 variable combinations
  • 9 million calculations

Sengupta said there were 35 key insights auto-detected by Lucid, the company’s business intelligence software. He highlighted three:

  1. For the exact same surgery, patients in one hospital were recovering 14.5 days earlier than patients in another.
  2. Patients with “altered mental status” had 7.5 days excess length of stay for surgeries across all hospitals.
  3. Patients with one particular insurance who received a certain treatment were staying 20 extra days.

Sengupta said this analysis made the extent of the problems much more clear.

“Most of the time, executives don’t have the information at their fingertips to identify these problems,” Sengupta said. “They can’t collaborate within the organization to find the solutions.”

Physician Targeting Using Real-time Data: How PurpleLab’s Alerts Can Help

By leveraging real-time data that offers unprecedented insights into physician behavior and patient outcomes, companies can gain a competitive advantage with prescribers. PurpleLab®, a healthcare analytics platform with one of the largest medical and pharmaceutical claims databases in the United States, recently announced the launch of Alerts which translates complex information into actionable insights, empowering companies to identify the right physicians to target, determine the most effective marketing strategies and ultimately improve patient care.

Sengupta said BeyondCore takes a search-oriented approach to statistics to provide “advanced analytics for all.” This lets users ask questions without writing queries.

“We had to come up with our own proprietary approach, but you could replicate this in any system and focus on examples instead of statistics, for example,” he said. “The principal is more important than the code.”

Sengupta said the executive dashboard uses tiles to represent reports.

“You flip the tile and it shows more detail for each example,” he said.

One audience member asked how an analyst could be sure the computer is doing its job given the visual approach to reporting.

To make sure his team could win debates with statisticians, Sengupta said the system also allows a business analyst to see the variables and see each examples for each variable combination.

“They can see the regression and determine what is R-squared as well,” Sengupta said.

Today is the second day of O’Reilly’s Strata conference that includes some of the other speakers in the webinar. You can watch the event and check out the agenda here.
