The WHO guidelines: the new and the old

Abstract

Purpose of the review The original World Health Organisation (WHO) cancer pain guidelines were published in 1986 and used globally. Updated guidance was released in 2018. This review compares the ‘old’ with the ‘new’ with a closer look at the relevance of the WHO analgesic ladder in the current climate. Recent findings The new guidelines provide a more evidence based, rigorously developed document including recommendations relating to radiotherapeutic management. There is a more detailed focus on safe opioid prescribing, opioid stewardship and the importance of integrating pain management expertise early on in the cancer journey. There remains a lack of evidence for certain therapies despite their widespread use particularly in relation to adjuvants. The pitfalls of the original renowned analgesic ladder are highlighted including a recognition that omitting ‘step 2’ is safe, feasible and cost effective. Summary The new guidelines offer more detailed recommendations relevant to clinical practice with a strong focus on safety of opioid prescribing making it relevant in the current climate. The original WHO analgesic ladder is no longer recommended as a strict protocol for cancer pain management.
