Case Study: Nationwide Grocery Chain achieves $3.8M in annual medical cost savings and 41% fewer ER visits with Castlight Health

National grocery chain helps employees make better healthcare decisions

A leading national grocery chain facing rapidly rising healthcare costs introduced a high-deductible health plan (HDHP) but found employees—accustomed to HMO/PPO coverage—weren’t equipped to shop for value-based care. The company needed an easy, personalized way to help workers understand benefits, anticipate costs, and manage medical spending.

The grocer deployed the Castlight health benefits platform—web and mobile tools for cost-and-quality comparisons, targeted engagement campaigns, and reference-based pricing—to guide employees to lower-cost, high-quality care. Castlight users experienced a 14% lower medical trend (about $3.8M saved in one year), 41% fewer ER visits, and double-digit reductions in imaging (‑16%), lab tests (‑12%) and office-visit costs (‑14%).
