Assessing and stratifying risk of infections are essential to prevent infection in these patients. To date, no tool can fulfill this demand in China. This study aimed to develop a nursing work-based and Chinese-specific tool for pediatric nurses to assess risk of infection in oncology patients. This research was a modified Delphi study. Based on a literature review, a 37-item questionnaire rating on a 0-5 scale was developed. Twenty-four experts from 8 hospitals in 6 provinces of China were consulted for three rounds. Consensus for each item in the first round was defined as: the rating mean was 〉 3 and the coefficient of variation (CV) was 〈 0.5. Consensus for each item in the second round was defined as CV 〈 0.3. Consensus among experts was defined as: P value of Kendall's coefficient of concordance (W) 〈 0.05. After three rounds of consultation, a two-part tool was developed: the Immune Status Scale (ISS) and the Checklist of Risk Factors of Infection (CRFI). There were 5 items in the ISS and 14 in the CRFI. Based on the ISS score, nurses could stratify children into the low-risk and high-risk groups. For high-risk children, nurses should screen risk factors of infection every day by the CRFI, and twice weekly for low-risk children. Further study is needed to verify this tool's efficacy.展开更多

Although guidelines have been updated, those with detailed protocols are limited for nursing practice. This study aims at establishing an early assessment and intervention protocol as a toolkit for PPH for midwives and obstetrical nurses.Methods: Employing the evidence-based method, a systematic Internet search of guidelines was conducted and appraisal of literatures was conducted with AGREE system and Oxman-Guyatt Overview Quality Assessment Questionnaire(OQAQ), according to which a protocol draft was therefore developed. Then, a two-round modified Delphi method was utilized to reach a consensus of the protocol built on best practices. Selection criteria for each intervention measure included consensus level with a threshold of 70%, mean of importance(M) >3.5, and coefficient of variation(CV) <0.25. Reliability of experts' opinion was calculated by positive coefficient and authoritative coefficient. Items without consistency were enlisted in the second-round consult. When all items met the selection criteria, the protocol would be finally formulated.Results: A 122-measure protocol was established, including prevention, assessment, and intervention of PPH. With a panel of 14 experts participated in the consult, the positivity coefficient was 0.93 and 1.00 for two rounds, respectively, and the authority coefficient was 0.88. After a two-round consult and revision of the draft, the final program was formulated, containing 5 first-level indexes and 14 second-level indexes with a total item of 120.Conclusions: The PPH protocol, based on high-quality evidences, was formulated with a two-round Delphi method, which can provide insight for midwives and obstetrical nurses to effectively deal with PPH.展开更多

However, research on integrating traditional and complementary medicines(T&CM) into conventional health care is lacking. T& CM approaches, may provide a cost effective option given the increase in chronic diseases with evidence of effectiveness of T& CM being key if such approaches are to be offered as part of integrative patient care, in most countries, an integrated healthcare approach is unavailable to patients. Evidence based clinical guidelines on T& CM should influence care provision. However evidence that is available may not even be cited. Poor use of evidence may possibly be a reflection of lack of knowledge and/or biases of guideline developers but additionally stakeholders vary in their perceived need for evidence to implement health policy change. Journal editors should focus on publishing high quality manuscripts, with clear rationales, design and reporting frameworks. Researchers should consider carrying out careful feasibility studies prior to conducting trials taking into account the UK Medical Research Council's framework on complex interventions. Examples of feasibility studies highlighting their importance for trial design are given in this paper. If preparation for more definitive studies is conducted this will in turn improve the quality of research being designed, executed and published and subsequently encourage the inclusion of evidence by guideline developers. Robust evidence is necessary in order to inform governments' health policies providing appropriate T&CM interventions which can ultimately help to provide best patient care.展开更多
