Although difficult to quantify, there is known widespread variation in the way that best available evidence is applied in clinical practice. The reasons for gaps between evidence and practice are complex, and efforts to improve uptake are unlikely to be successful if they are one-dimensional or focus on individual health professionals. This article provides contextual reference for articles in this Supplement in addressing how and why clinical variation exists, the importance of reducing it and strategies to drive a more streamlined approach to evidence-based care in Australian health care systems.
尽管难以量化，但在临床实践中应用最佳现有证据的方式存在广泛的差异是已知的。造成证据与实践之间差距的原因很复杂，如果改进措施是单一维度的或只关注个别卫生专业人员，那么这些措施不太可能取得成功。本文为本期增刊中论述临床变异存在的方式和原因、减少变异的重要性以及在澳大利亚卫生保健系统中推动更精简的循证护理方法的策略的文章提供了背景参考。
