Aon has released its 2021 Global Medical Trend Rates Report, which provides an overview of medical plan costs and trends from countries around the world. The report surveyed 107 Aon offices that broker, administer, or otherwise manage medical plans globally, and provides information on the growing prevalence of employee cost-sharing practices in medical plans. The report also includes qualitative responses to provide greater context to the survey results. The report summarizes the most typical (modal) practices in each covered country in regard to employee sharing in medical premium and claim outlays. The report provides insights into the key conditions driving adverse medical claims experience and risk factors driving claims escalation. The report also includes tables of average medical trend rate and other survey results. The report concludes with a glossary of terms and a list of contacts for further information.
