The resistance to changing guidelines – what are the challenges and how to meet them

Bridging the gap between scientific evidence and its practical application is of the utmost importance in improving the quality of care and increasing patient safety. Guidelines based on evidenced-based medicine (EBM) have led to improved performances and better outcomes. However, even though scientific data are available, resistance to adopting evidence-based guidelines is still enormous. Significant barriers hinder the introduction of best medical practice into the daily clinical routine. The barriers to implementing change are complex, multifunctional, and influenced on many levels by various interests both inside and outside the health-care system. Political, organizational, financial, cultural and scientific interests are regarded as being as important as the perception of patients and health workers. Strategies need to be planned which take account of the multidimensional character of quality of care and incorporate it at the various levels. The conclusion, therefore, is that we need to combine methods and tools to tailor our interventions to the patient's needs.

Definition of clinical guidelines

According to Field and Lohr:13 ‘clinical guidelines are systematically developed statements to assist practitioner or patient decisions about appropriate health care for specific clinical circumstances’. They are based on the best available scientific evidence to provide clinicians with guidance to ensure that best practice is offered to patients.3 Guidelines are supposed to evaluate the wealth of scientific data, clarify different points of view, and finally define state-of-the-art procedures.

The process of change: the case of preoperative fasting

Unlike the field of industry, where people are forced to bring new ideas into practice because of fierce economic competition, it seems that within health systems the issue of ‘how to make guidelines work’ has always played a minor role.12, 17 As a consequence, data concerning the implementation process of liberalized guidelines for preoperative fasting are rare. Nevertheless, since several anaesthesiology societies from different countries have officially changed their recommendations for

Summary

As we have seen, clinical guidelines are meant to facilitate best medical practice. One might therefore expect them to be widely used. However, research has shown that the existence of an excellent guideline guarantees neither its wide nor its consistent use. Besides the efforts being made in developing guidelines, a lot more has to be done to encourage their implementation. Identifying the vast number of obstacles to any change in clinical practice is a decisive part of an implementation
