Overall Change after CDHC Implementation
Pre-CDHC and post-CDHC, all differences were statistically significant. Compared to the pre-CDHC period, the post- CDHC period saw more pediatric patients, delivered more care, and documented fewer missed appointments (see Table 1 below). Care value per procedure was slightly higher during the pre-CDHC period, but total care value per patient was no different between the pre-CDHC and post-CDHC periods (see Table 2). Procedure mix was similar for both periods (see Table 3).

New Patients
New pediatric patients were defined as those who did not have a visit between March 2010 and May 2012. Of the 707pediatric patients who had a visit at the clinic after May 2012, 195 (27.6%) were new.
Summary
Despite the lower care value per procedure, the post-CDHC period did see a larger total care value overall ($148,947) compared to the pre-CDHC period ($131,841), an increase of $17,106. Overall, the post-CDHC period saw a 19% increase in number of pediatric patients, a 14% increase in number of visits, and a 17% increase in number of procedures.
i Some patients visited the clinic during both time periods, so they are counted in the pre-CDHC group and in the post-CDHC group.
