Experts agree there is at least the potential for secular changes to slow medical costs in the future. In a recent study, Thomas Getzen, of Temple’s Fox School of Business, and co-authors say changes in practice patterns, driven by both the Affordable Care Act and economics, could slow future cost growth. Their main argument is it far too soon for cost changes from the payment and delivery reforms of the ACA to show up in current cost statistics, not that these reforms won’t eventually slow spending by measurable amounts.
