1.1 Set up a research group
The research team is composed of 11 people, including 1 professor engaged in clinical nursing research, 1 associate professor engaged in clinical nursing research, 1 chief physician of gastrointestinal surgery, 1 head nurse of gastrointestinal surgery, 2 wound ocenterologists, 2 chief nurses of gastrointestinal surgery, and 3 graduate nursing students. The research team is responsible for consulting and analyzing the literature, designing the interview outline, determining the interview objects and the letter experts, making the expert letter consultation form, sorting out and analyzing the feedback results of each round of expert letter consultation, and making group discussions to determine whether the indicators need to be added, modified and deleted.
1.2 Preliminary formulation of a rating system
1.2.1 Theoretical basis
This study, under the guidance of "knowledge, trust and practice theory" [16], constructed the evaluation index system of high displacement health education in patients with preventive ileostomy for rectal cancer. This theory holds that knowledge is the basis of positive attitude, positive belief is the driving force for behavior change. purposeful and planned educational activities can improve the knowledge level of patients and change their attitude and behavior, thus improving their health status and quality of life[9]。
1.2.2 Literature search
With "rectal cancer" "sphincter-preserving/anal-sparing surgery/sphincter-saving surgery" "temporary ostomy/temporary diversion stoma/prophylactic stoma/ileostomy/diverting loop ileostomy/ileostomy diarrhea/preventive terminal ileostomy/high output stoma "" health education/education/health need*/nursing need*/care need*/information need*/information preference "" evaluat*" For the search terms, Search CNKI, Wanfang database and VIP database and other Chinese databases, PubMed, Wound, Ostomy and Continence Nurses Society(WOCNS), American Society of Colon and Rectal Surgeons( ASCRS), Web of Science, Cochrane Library and other English databases. The search period is until April 7, 2024. Inclusion criteria: ① The study topic was related to high displacement of ileostomy after rectal cancer; ② in Chinese or English. Exclusion criteria: ① duplicate, inaccessible full text; ② abstract, conference paper and research plan. The preliminary search obtained 4832 related articles, including 4119 articles, including 2243 in English and 1876 in Chinese. According to the titles, abstracts and full texts, 52 articles were selected, including 31 in English and 21 in Chinese. Two people read the literature carefully and wrote the first draft of the evaluation indicators. Through the research team discussion, they determined the three first-level indicators of health knowledge, health belief, health behavior, 18 second-level indicators and 82 third-level indicators according to the theory of knowledge, trust and practice.
1.2.3 Semi-structured interview
Using the objective sampling method, from January 2024 to March 2024,10 patients with high displacement of rectal cancer and 5 stoma nurses in a grade a hospital in Shanxi Province were selected for semi-structured interviews.
Inclusion criteria were: (1) Patients: ① 24 h prophylactic ileostomy displacement > 1 500 mL; ② volunteered to join the study and signed informed consent.(2) Nurses: ① has worked in colorectal and anal surgery for 10 years; ② has obtained the qualification certificate of stoma specialist nurse; ③ is highly motivated for this study and is willing to participate in this investigator.
The interview outline is as follows: (1) Patients: ① What difficulties do you encounter in enterstomy flow management?② From the perspective of health education, what help do you want medical to give?③ What is your attitude on enterostomy flow management?(2) Nurses: ① What health guidance do you think should be given for patients with high displacement stoma?② Does your department have a targeted evaluation tool for the health education of enterostomy high displacement management? What do you think are the evaluation indicators?
Face-to-face interviews were conducted after obtaining informed consent from experts and patients, ranging from 20 to 30 min, and the interview materials were recorded and audio-recorded by the interviewer. After the interview, the researchers use Colaizzi 7 step analysis to the interview data analysis, according to the results of the index, added "improve sleep quality method" "home nutrition assessment and monitoring method" "liquid, food intake calculation" "near hospital enterostomy health knowledge lecture or sunshine home activities" 20 level 3 indicators. Finally, the research team initially constructed the evaluation index system (draft) of high output health education for medium and low rectal cancer, including 3 first-level indicators, 18 second-level indicators and 102 third-level indicators.
1.3 Expert letter inquiry
1.3.1 Design the letter questionnaire
The expert letter inquiry questionnaire consists of three parts.① Letter to experts: introduce the research purpose, method, questionnaire filling instructions and time.② Expert evaluation form of the effect evaluation system of high discharge health education for patients with preventive ileostomy of rectal cancer.③ Basic information table of experts: including gender, age, education background, professional title, unit name, working field, working years, etc.④ Self-evaluation table of expert familiarity degree, judgment basis and influence degree.
1.3.2 Consultation with experts for selection
In this study, 20 experts from 10 Grade A hospitals in 5 provinces including Beijing, Shanxi, Henan, Shaanxi and Hunan provinces were selected for letter inquiry. Expert selection criteria: ① Clinicians should work in colorectal and anal surgery in a third-class hospital for 10 years; ② obtained internationally certified stoma therapist certificate or nurses participating in the training of stoma nurses; ③ All experts need bachelor degree or above, intermediate or above title; ④ have high enthusiasm in this study and are willing to participate in this investigator.
1.3.3 Implementation of expert letter consultation
From March to April 2024, the researchers sent the first round of expert letter inquiry questionnaire to all the experts through wechat and email, and asked the experts to return the letter questionnaire one week later. The research team modified the indicators according to the expert opinions and item screening criteria, formed the second round of expert letter inquiry form, and distributed them to the experts, inviting the experts to demonstrate the newly formed indicators again. And the mean < 3.5 and coefficient of variation > 0.25 [17].
1.4 Statistical analysis
The data were analyzed and processed by the Excel 2010, SPSS 26, and yaahp 10.3 statistical software..0 The frequency and composition ratio of expert age and working years are expressed by mean and standard deviation. The activity of experts is expressed by using the recovery rate of valid questionnaires and the submission rate of questionnaire opinions. The coefficient of expert authority degree (Cr) is determined by the judgment basis coefficient (Ca) and the familiarity degree coefficient (Cs). The calculation formula is: Cr = (Ca + Cs) / 2, and Cr 0.7 is taken as the acceptable range. The degree of concentration of expert opinion is expressed by the mean and standard deviation of index importance; the degree of coordination of expert opinion is expressed by the coefficient of variation and Kendall harmony coefficient, and P < 0.05 is significant. The hierarchical analysis method was adopted to determine the Satty scale by the difference of the importance assignment mean of the second round of expert letter inquiry, the index judgment matrix was constructed, and the weight of each index, combination weight and consistency coefficient (CR value) [18] were calculated.
