Case Study: Guadalupe Regional Medical Center achieves 40% increase in mammograms with Strata Decision Technology

How One Regional Health System Leveraged Data to Grow Its Services, Enhance Patient Care

Guadalupe Regional Medical Center (GRMC), a 153‑bed hospital in Seguin, Texas, faced growing patient leakage for mammography services—about 21% of patients in its primary service area were going elsewhere—largely because a single imaging machine created two‑ to three‑week scheduling backlogs. To understand referral patterns and service gaps, GRMC used Strata Decision Technology’s Market Share & Trending tool, Market Opportunity Analysis, and proprietary 837 All‑Payor Claims Data to quantify where patients were seeking care and why.

Using Strata Decision Technology’s analyses, GRMC built a state‑of‑the‑art women’s imaging center (opened 2021) with two mammography units and expanded diagnostic services; this reduced mammogram wait times by ~75%, drove nearly a 40% increase in mammograms annually, and cut the share of patients seeking mammograms elsewhere by more than 10%. GRMC continues quarterly market reviews to guide service-line decisions and improve timely access to care.
