The success of any QI project depends on a CHC’s ability to select suitable measures and assess the extent to which implemented changes lead to improvement. For the project, CHCs will monitor the PCCC and eCQMs (i.e., their “core measures”) side-by-side to identify initial gaps in the quality of their contraceptive care and track improvements over time. CHCs also may wish to identify complementary processes and balancing measures to support their analysis of core measures.
