It used to take 50 years for medical knowledge to double. Now it’s estimated at 73 days.

WorldCare’s multidisciplinary teams bring precision and expertise to each review, reducing misdiagnoses, avoiding unnecessary treatments, and replacing “trial-and-error” care with clear, evidence-based recommendations that improve outcomes and reduce overall costs.
WorldCare partners with insurers, employers, and health organizations to integrate Medical Second Opinion (MSO) services into existing health and benefits programs. This gives members fast access to expert case reviews, improving outcomes while helping organizations reduce healthcare costs.
We focus exclusively on serious and complex conditions. Each case is reviewed by multidisciplinary teams (MDT) from The WorldCare Consortium®, a network of top U.S. academic hospitals. This collaborative approach ensures every member receives accurate diagnoses and evidence-based treatment recommendations.
WorldCare MSOs deliver proven results:
1 in 4 cases result in a changed diagnosis
3 in 4 lead to a revised treatment plan
These insights reduce misdiagnoses, prevent unnecessary treatments, and strengthen trust and satisfaction among members.
Our MSO solutions are fully scalable and customizable. They can be easily added to existing benefit structures, health plans, or partner services, providing immediate value for both organizations and members. Visit our Global Contacts Directory to get in touch.
