Disparities in the healthcare are simply the clinical differences in outcomes such as healthcare stem, disease prevalence, mortality that are experienced by comparing one population with other (A report by AHRQ, 2010). Such differences are described by various attributes such as race, language, sex, financial status, ethnicity, social status and health literacy. Despite different understanding about the disparities, it is uncertain to identify the strategy that can enhance to quality of patient care in an effective manner and reduce discriminations among populations (Smedly BD, & Nelson AR., 2003)
As discussed above, Quality improvement is a multidisciplinary, data-driven and systems-focused method of evidence based practice in healthcare that support to improve the effectiveness, and reliability of healthcare processes and its outcomes. QI intervention was defined as a process change in different health care systems, or suppliers enabling optimal clinical quality of care.
An intervention is a strategy targeting at minimizing the quality gap that is the difference between health care systems or its outcomes those are observed in practice and existing evidence-based research (Shojania KG, Wachter RM, et al., 2004). There are four significant elements identified for the ongoing process of quality improvement; 1) performance goals, 2) measures, 3) practices and 4) feedback & reporting (Seid M, Williams VL et al., 2006).
Wide range of initiatives is focused to improve the quality of healthcare nursing and various approaches, models and tools are used in the hospice. Powel A., and Davis H. (2009) identified total quality management (TQM), Business process reengineering, continuous quality improvement, lean thinking, six sigma, etc., are most significant tools for such initiatives.
干预是一种策略，针对最小质量的差距，不同的卫生保健系统或其结果之间观察到在实践和现有的实证研究（shojania公斤，Wachter RM，等。，2004）。有四个重要的因素是质量改进的持续的过程；1）绩效目标，2）的措施，3）的做法和4）反馈和报告（SEID M，威廉姆斯六世等人。，2006）。
