Developing Event-Level Estimates. The data in this file can be used to develop national 2015 event-level estimates for the U.S. civilian noninstitutionalized population on prescribed medicine purchases (events) as well as expenditures, and sources of payment for these purchases. Estimates of total number of purchases are the sum of the weight variable (PERWT15F) across relevant event records while estimates of other variables must be weighted by PERWT15F to be nationally representative. The tables below contain event-level estimates for selected variables. Selected Event (Purchase) Level Estimates All Prescribed Medicine Purchases Estimate of Interest Variable Name Estimate (SE) Number of purchases (in millions) PERWT15F 3410.5 (101.08) Mean total payments per purchase RXXP15X $109 (4.2) Mean out-of-pocket payment per purchase RXSF15X $14 (0.4) Mean proportion of expenditures paid by private insurance per purchase RXPV15X /RXXP15X 0.191 (0.0053) Example by Drug Type: Statins (TC1S1_1 = 173 or TC1S1_2 = 173 or TC1S2_1 = 173 or TC1S3_1 = 173 or TC2S1_1 = 173 or TC2S1_2 = 173) Estimate of Interest Variable Name Estimate (SE) Number of purchases (in millions) PERWT15F 232.3 (8.65) Mean total payments per purchase RXXP15X $75 (2.8) Mean annual total payments per person RXXP15X (aggregated across purchases within person) $406 (16.3)
