Highlighting Hospital Patient Share

January 15, 2013


The latest addition to the Billian's HealthDATA Portal puts hospital market share under the magnifying glass, offering subscribers a glimpse into patient volumes by resident zip code. Sourced from CMS, this new Service Area data highlights the zip codes where patient days and charges stem from for over 5,800 U.S. hospitals.
 
Examining Hometown Patient Trends
Billian researchers took a look at patient trends in our hometown of Atlanta, GA to see which hospitals carried the bulk of 2011 inpatient traffic for the 30328 zip code (the city’s Sandy Springs/Marietta suburb).

Patient Stats on Hospitals Serving 100+ Residents in the 30328 Service Area
Hospital Total Cases %Δ Cases Total Days %Δ Days Total Charges %Δ Charges % Total Charges
St. Joseph's Hospital 551 23.27% 2,507 19.15% $17,289,171 22.21% 5.36%
Northside Hospital 193 -9.39% 947 -14.49% $7,897,512 -8.32% 3.52%
Piedmont Hospital 102 -8.93% 695 5.95% $5,912,025 31.29% 0.95%
Per CMS service area data, sourced via the Billian's HealthDATA Portal.
Values reflect 2011 data, as compared to 2010.

Three Atlanta hospitals served 100 or more residents in the 30328 zip code during the course of 2011. Both St. Joseph’s Hospital of Atlanta and Northside Hospital saw more patients from this zip than any other, with the Sandy Springs suburb coming in as the 24th-most-serviced zip code for Piedmont Hospital.
 
St Joseph's, the city's oldest inpatient facility and part of Emory Healthcare, saw a 20% gain in cases, days and charges from 30328 residents compared to the prior year, while Northside experienced a near-9% drop in cases and charges from that area year-over-year.
 
Northside’s losses in what has historically been its primary service area, coupled with 85%+ gains in patient charges from the nearby North Buckhead area (zip code 30342), paint a picture of possible market repositioning for the hospital.
 
Bringing it All Together
While there's little surprise in the notion that most inpatient visits occur at the facility nearest the patient, new MD alliances, facility mergers and acquisitions, and ACO initiatives will undoubtedly produce shifts in patient market share beyond typical census fluctuations.
 
As providers become more competitive, keeping a close eye on these subtle and sometimes rapid changes in patient market share will be paramount. Coupled with comparative insight into hospitals’ clinical performance outcomes, fiscal standing, patient ratings, etc., healthcare providers and suppliers can begin to build a better ‘big data’ perspective to more effectively track and respond to changes in the business of healthcare.
