The role of clinical guidelines in establishing competent professional practice

Is it too early to recommend local treatment in oligometastatic non-small cell lung cancer: a plea for equipoise

Oligometastatic non-small cell lung cancer (OMD NSCLC) has been proposed to bridge the spectrum between non-metastatic and widely metastatic states and is perceived as an opportunity for potential cure if removed. Twelve clinical trials on local treatment have been reported, yet none are conclusive. These trials informed the development of a joint clinical practice guideline by the American & European Societies for Radiation Oncology, which endorses local treatment for OMD NSCLC. However, the heterogeneity between prognostic factors within these trials likely influenced outcomes and can only support guidance at this time. Caution against an uncritical acceptance of the guideline is discussed, as strong recommendations are offered based on expert opinion and inconclusive evidence. The guideline is also examined by a patient's caregiver, who emphasizes that uncertain evidence impedes shared decision making.

'Advice, not orders'? The evolving legal status of clinical guidelines

Healthcare professionals are expected to deliver care that is consistent with clinical guidelines. In this article, we show that the English courts are increasingly willing to be persuaded by written guidelines when determining the standard of care in cases of alleged clinical negligence. This reflects a wider shift in the approach taken by courts in a number of common law jurisdictions around the world. However, we argue that written guidelines are still only one element that courts should consider when determining the standard of care. It is possible to deliver perfect care that deviates from professional guidelines and even to deliver negligent care by uncritically following a guideline that is flawed. We further argue that written guidelines are relevant beyond defining the accepted standard of care. This is because the decision to deviate from a guideline suggests the existence of multiple approaches that should be discussed with patients as part of ensuring informed consent. It is therefore likely that written guidelines will become an even more prominent feature of the medicolegal landscape in future years.
