“DPM” includes participating DPM facilities as of Sep 2010; “declined” includes sampled facilities that declined to participate or left the study prior to Sep 2010; “Non-DPM” includes facilities in the CMS sample frame that had not been selected for DPM participation as of Sep 2010. Values shown are means of CMS facility-level data. p values are for T tests comparing “Non-DPM” to “DPM” and comparing “Declined” to “DPM”, .”
