Cancer pain… who cares? International and national patterns of evidence-based global guidelines recommendations for...

Although pain is a common event during treatment of cancer, its assessment and management remains suboptimal in everyday clinical practice at global level.

Considering both the important role of internet in daily life and that clinical guidelines are important for translating evidence in clinical practice, we performed a prospective study to scrutinize the magnitude of updated evidence-based cancer-pain guideline recommendation for physicians on the web. Changes over-time at a global level were scrutinized at two time points: 2011 for baseline and 2018 at first follow-up. Both anesthesiology and oncology societies were analyzed.

In 2011 we scrutinized 181,00 WebPages and 370 eligible societies were identified; 364 of these were eligible for analyses both in 2011 and 2018. The magnitude of cancer pain updated and evidence-based guideline recommendations on the web for health care providers was extremely low at global level and at any time point considered: 1.1% (4/364) in 2011 and 4.7% (17/364) in 2018. Continental and intercontinental patterns, National's highest developmental index, oncology tradition and economic-geographic areas were not found to influence cancer pain web-guideline provision. In 2018, pain & supportive care societies provided the highest rate of updated evidence-based cancer-pain guidelines for clinicians. Only 3/25 medical oncology societies and 1/34 radiation oncology societies, provided own or e-link (to other societies') evidence-based guidelines in their websites.

Major medical oncology and radiation oncology societies - at global level - fail to produce updated cancer pain recommendations for their physicians, with most of these providing no or inconsistent or outdated guidelines.
