Study design:
We will use an exploratory sequential mixed methods approach starting with a qualitative data collection and analysis, followed by a quantitative data collection and analysis, and finally combining data from both. The study will include four phases.
In phase 1, we will collect qualitative data to explore breast cancer survivors’ sexual and reproductive health needs and related health services they receive in Iran. Data will be collected through in-depth semi-structured interviews with women who survived breast cancer, their husbands, and also health and medical service providers. We will use purposeful sampling to maximize diversity. Sampling will continue until data saturation. Data will be analyzed simultaneously using a conventional qualitative content analysis approach.
In phase 2, we will conduct a systematic review of all available guidelines, resources and documents on sexual and reproductive health of breast cancer or other cancers survivors worldwide.
In phase 3, the authors will draft the guideline using the results from phase 1 and 2. Subsequently, the draft will be circulated among a number of experts and service providers in the field. The guideline will be modified based on their suggestions and recommendations, finally, a meeting will be held with the panel of experts. We will use the nominal group technique (NGT) [23] to discuss the disagreements and finalize the guideline.
In phase 4, we will collect and analyze quantitative data to validate the guideline developed in phase three. This phase includes two steps. First, the Appraisal of Guidelines for Research & Evaluation II (AGREE II) Instrument [24] will be used to evaluate the guideline by the research team, experts from the nominal group and two experts outside the nominal group. In the next step, to assess the feasibility and applicability of the guideline, we will circulate it among a number of service Providers. We will evaluate their level of agreement with the recommendations. Their written suggestions will also be collected and integrated in the final version of the guideline.
This study was approved by the ethics committee in Tarbiat Modares University, Tehran, Iran (IR. MODARES. REC. 1397.207). The details of each phase are presented in the next section.
Phase 1: Qualitative study
Participants:
The participants will include three groups: breast cancer survivors (women) at different stages of the disease (diagnosis, treatment and follow-up), their husbands, and service providers with different levels of expertise.
We will use purposeful sampling for recruiting breast cancer survivors to maximize diversity in terms of age (peri or post-menopause), marital status (single, married, widowed or divorced), cancer stage, disease duration, and course of disease (diagnosis to follow-up). All participants (women with breast cancer and their husbands) should be willing to participate in the study, have Iranian nationality, can speak Farsi, and will be able to communicate to share their experiences.
The service providers will be selected from a wide range of people providing health and medical services to women with breast cancer including surgeons, oncologists, radiotherapists, nurses, midwives, obstetricians, infertility specialists, reproductive health specialists, counselors, psychologists, psychiatrists, follow-up personnel and policy makers. They should have at least two years of related work experience in public, private or semi-private sectors.
Study setting:
Participants will be recruited from the public, semi-private and private centers providing services to patients with breast cancer in Tehran. The time and place of the interview will be arranged, considering the participants’ choices.
Data collection:
The code of ethics will be reviewed and required permissions will be obtained in advance at each center. Eligible subjects will be informed about the research objectives and ethical considerations including confidentiality, no interference with the services they receive, destroying their audio files after completing the research, anonymity of the reports, and reflecting their views with honesty and no censorship. Subsequently, written informed consent will be obtained to record the interview and arrangement will be made in terms of time and place of the interview. In case the participant does not consent to record the interview, only notes will be taken.
The interviews with patients and service providers will be conducted by SR (PhD candidate, female). The interviews with husbands will be conducted by one of the male physicians within the study team (SAA) since Iranian men are more comfortable sharing their views with men due to Persian culture. The interviews will be semi-structured and expanded based on the participants’ replies to the initial general questions. General questions for breast cancer survivors will include: what sexual and reproductive health problems they have experienced after breast cancer diagnosis, what concerns them in this regard, if they have shared their concerns with anybody, and what health and medical services they have received. General questions for husbands will include: what has changed in their marriage and sexual life after their wife was diagnosed with breast cancer, how they have tried to solve the problems, and what health and medical services they have received. General questions for service providers will include: what sexual and reproductive health problems breast cancer survivors have, and what kind of health and medical services they receive in this regard. The audio files will be processed and analyzed as soon as possible following the interview. The interviews will continue until data saturation when no new information or codes is recorded.
Data analysis:
The data will be analyzed using the Graneheim & Lundman (2004) method. In this method, the entire interview is considered as the unit of analysis. Meaning units are words, sentences or paragraphs containing related aspects. The meaning units are then condensed based on their manifest (a description close to the text) or latent (an interpretation of the underlying meaning) contents. Subsequently, the condensed text is abstracted, and codes, categories and themes are created on varying levels [25].
Establishing rigor and trustworthiness:
We will ensure that the data is trustworthy described by credibility, dependability, confirmability, transferability and authenticity [26]. We will use different strategies to achieve credibility including prolonged engagement, member checking and maximum diversity sampling. We will spend sufficient time for each interview and also for processing them. The processed text from some interviews will be returned to the participants to evaluate their consistency. In addition, as mentioned above, we will use a purposeful sampling technique to maximize the diversity and capture a wide range of perspectives. Data collection will continue until data saturation, and we will use multiple methods to collect the data including interviews, field notes, and investigating all documents to increase the validity of the data. To achieve confirmability, we will present all interviews and extracted codes and themes to the experts within the study group as well as experts outside the study group who are interested in this field for further investigation and confirmation. To increase dependability, in addition to member checking, everything will be well documented and will be accessible. To increase transferability, a clear and detailed description of the context, participant selection process and characteristics, and data collection and analysis will be provided so that other researchers can decide if the findings can be transferred to their own settings. Constant observation, prolonged engagement, field notes, and detailed and comprehensive reporting will maximize authenticity.
Phase 2: Systematic review of available guidelines worldwide
SR and one other member of the study group will independently conduct literature review to find all relevant guidelines, documents and published papers in English or Farsi since Jan 1, 2000 using general search engines (e.g. Google); databases such as PubMed (https://pubmed.ncbi.nlm.nih.gov/), Cochrane Library (https://www.cochranelibrary.com/), ScienceDirect (https://www.sciencedirect.com/), Scopus (https://www.scopus.com/home.uri), Web of Science (www.webofknowledge.com), ProQuest (www.proquest.com), CINAHL (www.ebscohost.com), Trip Database (https://www.tripdatabase.com/), and Up ToDate (https://www.uptodate.com/); specific websites regarding clinical guidelines including Guidelines International Network (G-I-N) (www.g-i-n.net), National Institute for Clinical Excellence (NICE) (www.nice.org.uk/Guidance/), ClinicalKey (www.clinicalkey.com), Scottish Intercollegiate Guidelines Network (SIGN) (https://www.sign.ac.uk/), Agency for Healthcare Research and Quality (AHRQ) (www.ahrq.gov); internationally recognized cancer related websites such as ASCO (https://www.asco.org/), NCCN (www.nccn.org) and CCO (https://www.cancercareontario.ca); and Iranian databases such as SID (https://www.sid.ir), Irandoc (https://irandoc.ac.ir/), Magiran (https://www.magiran.com/) and Civilica (https://en.civilica.com/).
The following strategies will be used to search in PubMed and will be modified for searching in the other websites: (reproductive health[MeSH Terms]) OR (sexual health[MeSH Terms])) AND (cancer[MeSH Terms]) AND (guideline[MeSH Terms]) as well as (breast cancer[MeSH Terms]) AND (guideline[MeSH Terms]).
Subsequently, recommendations related to the study objectives will be selected and categorized into groups with regards to the supporting scientific evidence behind them. Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework will be used to evaluate the recommendations [27].
Phase 3: Guideline development
First, we will use PIPOH technique to develop a set of key questions[28]. This technique includes five items: Population concerned (survivors of breast cancer in Iran), Interventions of interest (sexual and reproductive health services), target Professionals (service providers at different levels), expected Outcomes (better sexual and reproductive health services), and Health care setting and context (all public, semi-private and private centers providing services to breast cancer survivors including health care centers, offices, clinics and hospitals).
Next, the study team members MR (health education expert), SAA (sexual health specialist), SH (epidemiologist), EM (methodologist) and SR (reproductive health PhD candidate) will use the findings from phase 1 and 2 to develop the guideline. Three techniques will be used: adoption (accepting existing recommendations from available guidelines as they are), adaptation (changing existing recommendations from available guidelines to meet local and cultural needs) and de novo development of recommendations if required [18]. Recommendations with more supporting evidence and compatibility with local and cultural circumstances will be prioritized.
After developing the initial guideline, we will use multiple techniques to ensure that the experts in the field all agree with the recommendations especially where evidence is not sufficient [23]. The guideline including recommendations and their supporting evidence will be sent to some experts in the field. We will ask them to give us their feedback based on their personal experience in written format. The study members will then investigate all comments and suggestions. Subsequently, a meeting will be held with a panel of experts. We will use NGT to discuss the items in the meeting. The recommendations with more than 80% agreement will be included in the guideline. For recommendations with disagreement, the study group will decide and this will be mentioned in the guideline. In this meeting, decision will also be made about how and when the guideline will be updated.
Phase 4: Guideline validation
This phase will include two quantitative steps.
Evaluating quality of the guideline from developers’ and experts’ perspective:
To evaluate the guideline quality, we will use AGREE II instrument to address its methodological rigor and transparency. AGREE II contains 23 items in 6 domains: scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability, and editorial independence. Each items are rated in a 7-point scale: from 1 strongly disagree to 7 strongly agree. Under each item, there is a space for further comments. A score is calculated for each of the six domains independently and should not be accrued into a single score. Domain scores are useful to evaluate the quality of the guidelines but there is no cutoff to classify high and poor quality guidelines. At the end, individuals will evaluate the guideline overall and will be asked whether they would recommend it or not. It is recommended that at least two and preferably four people access the guidelines [24, 29]. Here, the developed guideline will be evaluated by the guideline developers, experts from the nominal group and two experts outside the nominal group. AGREE II has been translated and used by Iranian researchers before [30].
Evaluating practicality of the guideline from service providers’ perspective:
To evaluate the practicality of the developed guideline, we will circulate it among at least 30 service providers asking them the last question in the AGREE II instrument to know if they recommend the usage of the guideline. We will also asked them if they have any suggestion to improve it. Subsequently, the comments and suggestions will be assessed by the research team and will be integrated in the final version of the guideline.
