Keeping More Information on Interviewing That Involved More than One Visit to Providers (3.8.3)

To achieve interview targets for both surveys (particularly in 2001), it was sometimes necessary to make more than one visit, on different days, to a provider. In 2001, summary information on these visits was combined and placed in a single data record on the analysis file. In 2005, we kept detailed data on each visit in separate data records. This allowed more complete and precise analysis of the sampling done at the sites.
