One setting where practice registry measurement has been implemented is the Health Resources and Services Administration s Health Disparities Cancer Collaborative HDCC . Methods Using practice registry data from 16 community health centers participating in the HDCC we determined the completeness of data for screening follow-up and treatment measures. We determined the size of the change in cancer care processes that an aggregation of practices has adequate power to detect. We modeled different ways of presenting before after changes in cancer screening including count and proportion data at both the individual health center and aggregate collaborative level. Results All participating health centers reported data for cancer screening but less than a third reported data regarding timely follow-up. For individual cancers the aggregate HDCC had adequate power to detect a 2 to 3 change in cancer screening but only had the power to detect a change of 40 or more in the initiation of treatment. Almost every health center 98 improved cancer screening based upon count data while fewer 77 improved cancer screening based upon proportion data. The aggregate collaborative appeared to increase breast cervical and colorectal cancer screening rates by 12 15 and 4 respectively p for all before after comparisons . In subgroup analyses significant changes were detectable among individual health centers less than one-half of the time because of small .
