2.6.0.0 Cost-ef­fec­tiveness

A cost-‍ef­fec­tiveness model sug­gest­ed that the lifestyle in­ter­ven­tion used in the DPP was cost-‍ef­fec­tive (32,33). Ac­tu­al cost data from the DPP and DPPOS confirmed this (34). Group de­liv­ery of DPP con­tent in com­mu­ni­ty or pri­ma­ry care set­tings has the po­ten­tial to re­duce over­all pro­gram costs while still pro­duc­ing weight loss and di­a­betes risk re­duc­tion(35-37). The use ­of com­mu­ni­ty health work­ers to sup­port DPP ef­forts has been shown to be ef­fec­tive with cost sav­ings (38) (see Sec­tion 1 “Im­prov­ing Care and Pro­mot­ing Health in Pop­u­la­tions” for more in­for­ma­tion). The CDC co­or­di­nates the Na­tion­al Di­a­betes Pre­ven­tion Pro­gram (Na­tion­al DPP), a re­source de­signed to bring ev­i­dence-‍based lifestyle change pro­grams for pre­vent­ing type 2 di­a­betes to com­mu­ni­ties (www.cdc.gov/di­a­betes/pre­ven­tion/index.htm). Early re­sults from the CDC’s Na­tion­al DPP dur­ing the first 4 years of im­ple­mentation are promis­ing (39). In an ef­fort to ex­pand pre­ventive ser­vices using a cost-‍ef­fec­tive model that began in April 2018, the Cen­ters for Medi­care & Med­i­caid Ser­vices has ex­panded Medi­care re­im­burse­ment cov­er­age for the Na­tion­al DPP lifestyle in­ter­ven­tion to or­ga­ni­za­tions rec­og­nized by the CDC that be­come Medi­care sup­pli­ers for this ser­vice (https:/‍/‍innovation.cms.gov/initiatives/medicare-di­a­betes-pre­ven­tion-pro­gram/).
