Objective To select and summary the best evidence on prevention and management of the skin adverse reactions in patients with targeted tumor therapy,and to provide references for clinical decision. Methods We systematically searched for the evidence on prevention and management of the skin adverse reactions in patients with targeted tumor therapy in BMJ best practice,UpToDate clinical decision system,Joanna Briggs Institute,Guidelines International Network,National Institute for Health and Clinical Excellence,Scottish Intercollegiate Guidelines Network,Yi Maitong Guidelines Network,National Guideline Clearinghouse,the Agency for Healthcare Research and Quality,Registered Nurses’ Association of Ontario,World Oncology Network,National Comprehensive Cancer Network,Lung Cancer Committee of China Anti-Cancer Association,Chinese Anti-Cancer Association Oncologic Nursing Comittee,Cochrane Library,Embase,CHINAL,Web of Science,OVID,PubMed,SinoMed,CNKI,WanFang database,VIP database to collect the literature,including clinical guidelines,evidence summaries,best practice information sheets,recommended practice,systematic reviews and original research. The retrieval period was from January 1,2011 to October 3,2021.There were 2 researchers evaluating the quality of the literature and extracting the data. Results 15 articles were selected,including 3 guidelines,4 evidence summaries,1 systematic reviews,3 randomized controlled trials,1 class experiment and 3 expert consensuses. 19 pieces of best evidence were formed from 6 aspects,including skin evaluation,risk factors,drug therapy,skin care,skin adverse reaction management and health education. Conclusion This study summarizes the best evidence on management and prevention of skin adverse reactions in patients with targeted tumor therapy,and provides evidence-based evidence for clinical workers and managers. It is suggested that clinical staff should combine clinical context,fully assess patient’s skin condition,do a good job of skin health education,examination and care to prevent the occurrence of skin adverse reactions.
