Global coverage and consistency of guideline recommendations for cancer cachexia on the Web in 2011 and 2018.

Cancer cachexia is a common associate of cancer and has a negative impact on both patients' quality of life and overall survival. Nonetheless its management remains suboptimal in clinical practice. Provision of medical recommendations in websites is of extreme importance for medical decision making and translating evidence into clinical practice. To scrutinize the magnitude, consistency and changes over time of cancer-cachexia recommendations for physicians on the Web among oncology related societies. Intercontinental, continental, national and socioeconomic variations were further analyzed. Web identification of oncology related societies and prospective analyses of relative Web guideline recommendations for physicians on cancer-cachexia at different time-points. In June 2011, we scrutinized 144,000 Web pages. We identified 275 societies, of which 270 were eligible for analyses: 67 were international (African, American, Asian, European, Oceania and Intercontinental), 109 belonged to the top 10 countries with the highest development index and 94 pertained to 10 countries with a long lasting tradition in medical oncology. The magnitude of cancer cachexia recommendations for physicians on the Web at a global level was scant both for coverage and consistency, and at any time-point considered: 3.7% (10/270) in 2011 and 8.1% (22/270) in 2018. The proportion of societies giving evidence-based and updated recommendations for cancer cachexia for physicians was only 1.1% (3/270) in 2011 and 2.96% (8/270) in 2018. Continent, national highest developmental index, oncology tradition and economic-geographic areas were not found to influence Web guideline provision.
