Objective:To retrieve, assess and summarize the best evidence for prevention and management of totally implantable venous access port blockage in malignant tumor patients.Methods:Literatures related to the prevention and management of infusion port blockage were searched by computer on BMJ Best Practice, UpToDate, Australian Joanna Briggs Institute Evidence-Based Health Care Centre Database, Guidelines International Network, National Guideline Clearinghouse, Cochrane Library, Ovid, PubMed, CNKI, Wanfang Database, VIP, Medlive, China Biomedical Medline Disc and other Chinese and English databases. The search period was from January 2013 to January 2023. Two researchers evaluated the quality of the literatures respectively, and the literatures that met the criteria were extracted, integrated and graded.Results:A total of 18 literatures were included, including 2 guidelines, 9 evidence summaries, 5 expert consensus articles and 2 systematic reviews. A total of 34 pieces of evidence were summarized from 6 aspects, including personnel training, nursing evaluation, catheter implantation, catheter maintenance, blockage management and health education.Conclusions:Summary of the best evidence for prevention and management of totally implantable venous access port blockage is comprehensive. Clinical medical staff should apply the evidence according to the medical situation to reduce the occurrence of blockage of infusion port.

Objective: To investigate the current status of knowledge and attitudes of oncology nursing staffs on pain management in cancer patients. Methods: A total of 232 oncology nursing staffs from 7 Grade III-A Hospitals in 4 provinces and municipalities were surveyed using General Information Questionnaire and knowledge and attitudes survey regarding pain (KASRP) (2014) questionnaire (Chinese version). Results: The results of this survey showed that the average score of knowledge and attitude about pain management of 232 oncology nursing staffs was (21.56±4.01) points, and the average correct rate was 52.59%. There were no significant differences in the scores of different education background, years of nursing work, years of cancer clinical nursing care, and the nature of the hospital they worked in(P>0.05). However, there was a difference in the score of nursing staffs with different professional titles (F=5.885, P=0.003). Besides that, difference also showed in scores of nursing staffs with different experiences in caring cancer pain patients (F=3.216, P=0.024). Conclusion The knowledge and attitude of pain management in oncology nursing staffs are in low level, the command of knowledge is not enough, meanwhile, the pain management ability is insufficient. Therefore, it is necessary to strengthen the training of pain related knowledge of nursing staffs and improve their pain management ability.
