Health care organizations require practical assessment tools to guide quality improvement efforts and evaluate changes in chronic illness care. In response to this need, the ICIC staff developed the Assessment of Chronic Illness Care ("ACIC", Bonomi et al., 2002) and the Patient Assessment of Chronic Illness Care ("PACIC", The MacColl Institute, 2004) surveys. 
Modeled after an instrument developed by the Indian Health Service for evaluating diabetes care (Acton et al., 1993, 1995), the ACIC is intended for use by medical teams to: (1) identify areas for improvement in care for chronic illness before beginning quality improvement work, (2) develop improvement strategies, and (3) evaluate the level and nature of improvements made in response to quality improvement interventions.
To assess the quality of chronic illness care delivery from the patient perspective, ICIC staff and colleagues developed the PACIC. It is a brief, validated patient self-report instrument assessing the extent to which patients with chronic illness receive care that aligns with the Chronic Care Model —measuring care that is patient-centered, proactive, planned and includes collaborative goal setting, problem-solving, and follow-up support. The results of our validation study of the PACIC were published in 2005. It has subsequently been used in multiple studies evaluating patient experiences of chronic illness care [Link].
