Abstract
The need for evidence-based guidelines as to how to conduct the sweat test in the UK was highlighted in 2000 by the National External Quality Assessment Scheme Specialist Advisory Committee. A Guideline Group supported by several professional bodies was subsequently convened and formal evidence-based guidelines were produced and published in 2003. The process of undertaking guideline production is summarized here, together with the author's personal opinions about the experience and highlights of the shortcomings and lessons learnt from the project. In summary, production of evidence-based guidelines is a long process and is only worth the effort (both man hours and financial) if the recommendations are subsequently adopted into clinical practice and in turn improve patient care. The emphasis for the future should be to assess the impact and value of evidence-based guidelines and promote their introduction into local practice as part of care pathways. A growing number of guideline initiatives emphasizes the importance of and a need for an overarching coordinating structure to overcome problems of duplication and enable interested professionals from different disciplines to work on related initiatives.
