Abstract

Introduction Women diagnosed with cancer and facing potentially sterilising cancer treatment have to make time-pressured decisions regarding fertility preservation with specialist fertility services while undergoing treatment of their cancer with oncology services. Oncologists identify a need for resources enabling them to support women's fertility preservation decisions more effectively; women report wanting more specialist information to make these decisions. The overall aim of the ‘Cancer, Fertility and Me’ study is to develop and evaluate a new evidence-based patient decision aid (PtDA) for women with any cancer considering fertility preservation to address this unmet need.

Methods and analysis This is a prospective mixed-method observational study including women of reproductive age (16 years +) with a new diagnosis of any cancer across two regional cancer and fertility centres in Yorkshire, UK. The research involves three stages. In stage 1, the aim is to develop the PtDA using a systematic method of evidence synthesis and multidisciplinary expert review of current clinical practice and patient information. In stage 2, the aim is to assess the face validity of the PtDA. Feedback on its content and format will be ascertained using questionnaires and interviews with patients, user groups and key stakeholders. Finally, in stage 3 the acceptability of using this resource when integrated into usual cancer care pathways at the point of cancer diagnosis and treatment planning will be evaluated. This will involve a quantitative and qualitative evaluation of the PtDA in clinical practice. Measures chosen include using count data of the PtDAs administered in clinics and accessed online, decisional and patient-reported outcome measures and qualitative feedback. Quantitative data will be analysed using descriptive statistics, paired sample t-tests and CIs; interviews will be analysed using thematic analysis.

Ethics and dissemination Research Ethics Committee approval (Ref: 16/EM/0122) and Health Research Authority approval (Ref: 194751) has been granted. Findings will be published in open access peer-reviewed journals, presented at conferences for academic and health professional audiences, with feedback to health professionals and program managers. The Cancer, Fertility and Me patient decision aid (PtDA) will be disseminated via a diverse range of open-access media, study and charity websites, professional organisations and academic sources. External endorsement will be sought from the International Patient Decision Aid Standards (IPDAS) Collaboration inventory of PtDAs and other relevant professional organisations, for example, the British Fertility Society.

Trial registration number NCT02753296; pre-results.

Strengths and limitations of this study

  • To the best of our knowledge, this research will develop the first, open access, evidence-based fertility preservation decision aid that is suitable for women of reproductive age (16 years+) and diagnosed with any cancer.

  • The research will provide evidence of its acceptability and utility to women and healthcare professionals in usual practice across cancer and fertility care pathways.

  • The research will provide evidence for the causal assumptions of its effectiveness and issues for implementation in usual care practice.

  • This research will not provide evidence of its effectiveness on healthcare outcomes. However, our findings will provide the evidence to inform the study design for evaluating the effectiveness of this complex intervention on health outcomes in the future.

Introduction

The impact of cancer treatment on female fertility

Approximately 50% of people in the UK will be diagnosed with cancer at some point in their lifetime.1 Owing to rising survival rates, the importance of addressing the late effects of cancer treatment, such as the risk of infertility, has increased.2 Chemotherapy, radiotherapy, hormonal, medical and surgical interventions may all affect female fertility. Although, the degree to which chemotherapy and radiotherapy impacts on gonadal function depends on the treatment agent administered, the dose, as well as the woman's age and levels of ovarian reserve at the time,3–5 loss of fertility is considered one of the most significant late effects of cancer treatment3 and cancer survivors often report it as one of the most distressing outcomes of their cancer treatment.6

The rationale for the study

Women diagnosed with cancer have to make time-pressured decisions about fertility preservation while simultaneously planning their cancer treatment. These decisions are stressful as women are having to trade-off the immediate consequences of starting cancer treatment with the long-term chances of having a biological child in the future, post cancer treatment. For those contemplating fertility preservation, women are required to move between two medical services (oncology and fertility services) to make care planning decisions collaboratively with fertility preservation and cancer teams.

In the initial stages of treatment for cancer, the American Society of Clinical Oncology and the American Society for Reproductive Medicine recommend options to preserve fertility which are discussed with each patient of reproductive age about to undergo cancer treatment which may affect their fertility.7 ,8 The current National Institute for Clinical Excellence (NICE) pathway for preserving fertility in people diagnosed with cancer presents similar guidelines for the UK.9 However, the evidence suggests that many women do not feel well supported in their choices, with many missing out on having fertility preservation at this crucial time. A recent UK survey by Breast Cancer Care found that as little as 12% of 170 women were referred to a fertility consultant, with many being unaware that infertility was a consequence following chemotherapy.10

Evidence from the medical and psychological literature examining aspects of fertility, pregnancy and decision-making following a cancer diagnosis have identified a range of factors which may hinder decision-making for this patient population.11–25 The barriers identified are diverse including financial concerns (especially in those countries where fertility preservation is not covered by insurance), fear associated with aggravating a hormone-sensitive cancer or a future pregnancy (in terms of a cancer recurrence and/or implications for the health of a future child) and lack of referral to fertility services (eg, due to reasons such as the oncologist prioritising cancer survival).

However, lack of fertility preservation information is also a key reason cited. The need for more evidence-based information that is integrated into the cancer care pathway early, and prior to transition to fertility services, has been identified as an important factor to facilitate women's decision-making at this time.26 ,27 It has been found that oncologists lack specific fertility preservation information for patients, and have only moderate confidence in their knowledge about fertility and the preservation options available.28 Therefore, they have also expressed the need for more evidence-based fertility preservation information to enable them to support women's decision-making more effectively.29

Patient decision aids

Patient decision aids (PtDAs) are information resources supporting people to make decisions between healthcare options.30 They are evidence-based resources, drawing on clinical effectiveness of healthcare options data, studies of patients' decision-making and illness experiences and evidence from the decision sciences on how people make healthcare choices.31 PtDAs support people to make reasoned decisions, that is, ones based on accurate information about the consequences of all options, in accordance with their beliefs, and trade-offs between their treatment preferences.32–34 Compared with usual care, receiving a PtDA helps people participate with their health professionals in making personalised choices between healthcare options.32 ,33 They have been shown to improve patients' knowledge of the risks and benefits of options, value of consequences to their lives and efficacy in making informed decisions.30

While there are many fertility preservation resources publically available for women with cancer,35 few exist to support the fertility preservation decision process in women of reproductive age.35 Of those publishing their development studies, two PtDAs were designed for women with breast cancer specifically, and none for women in the UK,36 ,37 despite women with a range of different cancers facing fertility preservation treatment decisions. It is therefore likely a new PtDA supporting women diagnosed with any cancer to make fertility preservations decisions will meet patient, service and practice needs.25 ,26 ,35

Aims and objectives

The aim of this research is to develop a fertility preservation PtDA enabling cancer and fertility services to support effectively women's fertility preservation decisions following a diagnosis of any cancer type.

Our objectives are to:

  1. develop a PtDA for use by oncology and haematology teams to support women making fertility preservation choices, while having a recent cancer diagnosis;

  2. assess the face validity of the PtDA to support women making informed decisions about fertility preservation before starting their cancer treatment and

  3. evaluate the acceptability of the PtDA using qualitative and quantitative methods to 1) women making fertility preservation decisions while planning their cancer treatment and 2) oncology, haematology and fertility health professionals supporting women's cancer and fertility treatment choices.

Evaluation of the PtDA should enable us to determine whether the provision of a PtDA early in the cancer care pathway better supports women, especially in the stressful intervening period between planning their cancer treatment and referral to the fertility expert. We also anticipate that the provision of this PtDA will enable women to make more informed fertility preservation treatment decisions, have more focused consultations with the fertility experts and a better opportunity to ask the right questions for them at the right time.

Methods and analysis

All aspects of the research are discussed with the steering group, and all stakeholders comment on all the materials. There has been patient and public involvement in the development of the research protocol and initial needs assessment. The PtDA is being developed across two regional cancer (adult, and teenage and young adult services) and fertility centres in Yorkshire. Ethics approval was granted on 5 April 2016.

Design

The Cancer, Fertility and Me PtDA was developed over a year using systematic and evidence-based methods (table 1—stages 1 and 2).33 ,38 ,39 A prospective, observational study using interview and questionnaire methods to evaluate the PtDA will be conducted (table 1—stage 3) informed by Medical Research Council Guidance for Developing Complex Interventions.40

Table 1

The three stages of the Cancer, Fertility and Me study

Stage 1: Development of the PtDA (November 2015—July 2016)

Stage 1 has used evidence to develop a PtDA supporting women to make informed decisions about fertility preservation options before starting cancer treatment. This will be for use alongside usual cancer and fertility care pathways.

The PtDA has used guidance from the International Patient Decision Aid Standards (IPDAS) collaboration34 on balance of options,41 ,42 risk presentation,43–45 eliciting values,46 ,47 use of patient stories,30 enabling readability48 and understanding illness.49 ,50 The guidance helps information to be structured so that it encourages people to evaluate all decision options, and their consequences, in accordance with their values and without bias, thus, enabling decision-making to be based on their trade-offs between these evaluations, that is, to make a reasoned decision.34

The aim is for women to receive the PtDA from their cancer health care professionals as part of usual care during the patient's first consultation to discuss cancer and/or fertility treatment options (this could be at cancer diagnosis), before referral to fertility services. The PtDA is being disseminated as a leaflet and PDF on a website, and evaluated accordingly. The content of the PtDA will be informed by evidence from the following:

  • Clinical guidelines on infertility and cancer prognosis, risks and benefits of cancer and fertility preservation treatment.8–9 ,35

  • Systematic narrative review of women's values, treatment preferences and decision-making experiences about fertility preservation when diagnosed with cancer, completed in June 2016. This was carried out as part of the previous PreFer study which was a 3-year mixed-methods prospective study exploring fertility preservation decision-making and quality of life in women with cancer.25

  • Environmental scan using systematic methods to synthesise evidence about open access resources for women with cancer about fertility preservation (patient information and clinical guidelines) and critically evaluate their ability to support informed decision-making, completed in May 2016.35

  • Observations of local service delivery, referral pathways within and across services and integration of research practices across regional National Health Service (NHS) centres for cancer and infertility services, completed by June 2016.

Regular meetings with the study steering group to decide the content and design of the PtDA. During this time web and graphic designers were involved in developing the PtDA's identity for use in health and patient forums, completed by July 2016.

Stage 2: Face validity study (July 2016–December 2016)

Stage 2 assesses the face validity of the PtDA for stakeholders. During the development of decision aids, this process is sometimes referred to as Learner Verification (LV).51 The aim is to assess the PtDA across stakeholders for attractiveness, comprehension, cultural acceptability, self-efficacy and persuasion.52 ,53

Sample

A purposive sample of eligible women and health professionals will be invited to participate from the study sites. All women of reproductive age (16 years +), diagnosed with any cancer and undergoing or has undergone cancer treatment(s) which may impact fertility will be eligible. The sample of health professionals will consist of adult and paediatric oncologists and haematologists, cancer surgeons, cancer nurse specialists and fertility specialists (clinicians, nurses and counsellors).

There is no statistical guidance for undertaking LV methods using qualitative methods. Prior literature and our research experience suggest a sample size of 20 participants in total across both sites to be appropriate.54 Therefore, 10 women and 10 health professionals from the two clinical centres will be invited to participate. In addition to the 20 participants, women and key health professionals will be invited to participate from relevant user groups/forums and professional organisations identified by the Cancer, Fertility and Me steering group and our systematic reviews (eg, National Cancer Research Initiative, Breast Cancer Care and British Fertility Society among others).

Recruitment

To recruit the women to stage 2, the nurses/clinicians will make the initial approach (for those women recruited from the two clinical centres). For the women recruited through the service user groups/forums, the lead contacts for the service user groups will make the initial approach. Following this, the contact details of the interested women will be passed to a trained researcher and those willing to participate will be sent the PtDA and associated documents to review by post. Recruitment of health professionals will be obtained from the study sites and through purposive and snowball sampling for the key stakeholders. The PtDA will be sent by post or via a PDF online depending on the request of the health professional. Appropriate consenting procedures and guidelines prescribed by the British Psychological Society55 and NHS research protocols will be followed.

Data collection

All the women and health professionals will be asked to complete a study questionnaire which includes the LV questionnaire, and the Preparation for Decision-making questionnaire.56 The LV questionnaire will consist of four items taken from the QQ-10,57 but will also comprise of three open-ended questions relating to the acceptability and utility of the PtDA from women's and health professional's perspective. The Preparation for Decision-making scale56 is a 10-item measure which assesses an individual's perception of how useful a PtDA is in preparing the respondent to communicate with their practitioner at a consultation focused on making a health decision. High scores on the overall scale (range 0–100) indicate higher perceived levels of preparation for decision-making.

Second, all the health professionals and women who completed the questionnaire and consent form, will be asked to take part in a follow-up telephone interview. An interview schedule will be used to seek their feedback and understanding of the purpose of the PtDA and study measures.51 ,53 Interviews will be audio recorded, digitalised and transcribed for analysis.

Data analysis

Telephone interviews will be coded and managed using NVivo 10 qualitative data analysis software. Analysis will use a practical, thematic approach outlined by Braun and Clarke58 using a systematic five-step approach: familiarisation, generating initial codes, searching for themes, reviewing themes and defining and naming themes.

Stage 3: Evaluation study (January 2017–May 2018)

Stage 3 evaluates the acceptability, feasibility and usefulness of the PtDA in clinical practice with women and health professionals. The study design employs mixed methods, using quantitative (stage 3a) and qualitative methods (stage 3 b).

Stage 3a Quantitative sample

All women receiving a new diagnosis of cancer from two regional centres will be eligible for participation. Inclusion criteria are women of a reproductive age (16 years +) with a new diagnosis of any cancer, and facing cancer treatment(s) with curative intent, which may impact fertility. We anticipate that the majority will be women with breast cancer, although women with lymphoma and leukaemia, head and neck cancers and cervical cancers are also likely to be represented in this research. From the results of our previous PreFer study,13 we have found that ∼90 women, across both hospital sites, aged between 16 and 40 years are diagnosed with cancer and face chemotherapy treatment annually and are eligible to receive the new PtDA. We identified around 17% of women from this group do not wish to consider fertility preservation as they already have children or never wanted children. During the 12-month period we hope to recruit ∼78 women in total, taking into account a 20% non-response rate from our previous data. Using a paired t-test to compare the outcome measures before and after the implementation of the PtDA, with 78 participants, we have 80% power at 5% two-sided significance to detect a minimum standardised effect size of 0.32.

Stage 3a Quantitative recruitment

We will adopt the ‘referral model’ for implementing the PtDA59 that is, the PtDA will be mentioned and discussed by their healthcare professional with any woman fitting the eligibility criteria during the patient's first consultation to discuss treatment options. The referral model proposes that these tools are ‘adjuncts’ that support decision-making, when used ahead of visits, or shortly afterwards.59 Eligible women will be invited to participate by the researchers working with the clinical care team, immediately following this consultation.

Stage 3a Quantitative data collection

Quantitative data will be collected at three time-points (figure 1). Questionnaire packs will be given to women at the same time as the PtDA (baseline); the timing of their attendance at the fertility clinic or cancer treatment starting point if not going to fertility services (time 1) and after their first session of chemotherapy (time 2a). The measures chosen for this study have been decided on following recommended guidance from the Patient Decision Aid International Research Group,60 and will assess the use of the PtDA and decisional preparedness.

Figure 1

Process flow chart for stage 3 evaluation study.

Baseline: questionnaire pack includes: The State Trait Anxiety Inventory—STAI-6,61 the EuroQol five dimensions questionnaire (EQ-5D),62 the Stage of Decision-making63 and the Decisional Conflict Scale.64 Women are instructed not to open and read the PtDA (or access it online) until they have completed the questionnaires.

The State Trait Anxiety Inventory—6 item45 is a brief 6-item version used to measure of state anxiety. All items are rated on a 4-point scale (1-Almost never, 4-Almost always). Higher scores indicate greater anxiety. The EQ-5D62 is a standardised instrument for use as a measure of health outcome. It consists of five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has three levels: no problems, some problems and extreme problems. The Stage of Decision-making63 is a 6-category tool to assess the individual's readiness to engage in decision-making, progress in making a choice and receptivity to considering or reconsidering options. The tool is rated on a 6-point scale (1-not thinking about it at all; 6-considered the options). The Decisional Conflict Scale64 is a 16-item scale which measures the patient's reported experience of making a reasoned and/or conflicted decision.

Scores >37.5 on the overall scale (range 0–100) indicate high decisional conflict, which is characterised by decision delay and/or uncertainty about decision.

Time 1: Questionnaire pack includes: the STAI-6,45 the Stage of Decision-making63 and the Preparation for Decision-making.56

Time 2a: Questionnaire pack includes: the STAI-6,45 the Stage of Decision-making63 and the Decisional Conflict Scale.64

Stage 3a Quantitative data analysis

We will report summary statistics for the count data and other service indicators. For the decisional outcome measures and other patient-reported outcomes we will use paired sample t-tests to calculate mean change in scores from baseline to time 1 and from baseline to time 2. 95% CIs for the mean changes will also be calculated. All statistical tests will be two-tailed with significance determined at p≤0.05.

Stage 3b Qualitative sample

Qualitative, semistructured interviews with a purposive sample of ∼30 women from the stage 3a evaluation (15 women from each site) and 30 health professionals including cancer surgeons, adult and paediatric oncologists and haematologists, nurse specialists and fertility experts (15 from each site) will be carried out. The purpose of the interviews are to gain a deeper sight into service user and healthcare professionals experiences of using the PtDA and its impact on the decision- making process and clinical care, within the context of this complex intervention.40 Although a total of ∼30 interviews are estimated, this will be guided by data saturation, following established protocols in qualitative research.58 ,65 ,66

Stage 3b Qualitative recruitment

The sample will consist of the women recruited into the stage 3 quantitative study, and the clinical sample will be obtained through snowball sampling methods. Women and health professionals will be issued with a study pack, including a study information sheet and the PtDA. On the day of the interview, an interview consent form will be completed. As shown in

Figure 1, the interview with women and the health professionals will be carried out after the first round of chemotherapy has been completed (time 2b) at a place that is most preferred.

Stage 3b Qualitative data collection

The interview schedule will comprise of the telephone interview LV schedule used in stage 2, with additional open-ended questions to add depth and breadth to the interpretation of the quantitative results enabling further insight into their experiences. It will also focus on LV and the PtDAs clarity and usefulness in planning care and making decisions between treatment options. However, additional areas we will explore include the PtDAs likelihood of use, barriers to use in practice, whether or not the women and health professionals benefit from their delivery, usefulness of the PtDA in aiding service transition and how the women used the PtDA.

All interviews will be audio-recorded and transcribed verbatim for analysis. Following the interview, the women will be given a final study pack questionnaire to complete, which comprises of the EQ-5D62 and the Decisional Regret Scale.67 The Decisional Regret Scale is a brief five-item scale which measures ‘distress or remorse after a health care decision’ using a 5-point Likert scale (1- strongly agree; 5- strongly disagree). A score of 0 on the overall scale (range 0–100) indicates no regret; scores of 100 mean high regret.

Stage 3b Qualitative data analysis

Interviews will be coded and managed using NVivo 10. Framework analysis will be carried out to identify recurrent themes which have been specifically developed for applied health and policy research.68 Independent analysis of the transcribed data by members of the study team and steering group will take place. Interdisciplinary analysis meetings will include critical appraisal of the literature, systematic data and coding framework verification and challenging of interpretive analysis. We will map the data against the themes identified from the existing literature as well as allow new themes to emerge. We will adhere to established quality criteria for qualitative research.58 ,65 ,66

Other questionnaires and outcome measures

Demographic information about women's age, ethnicity, employment and treatment status will be collected through a questionnaire during stage 2 (face validity) and at stage 3 baseline. Demographic information about health professionals will also be collected through a questionnaire, during stage 2 and at stage 3 (time 2b). Details of patients' cancer treatment(s) will be recorded at the end of the study using a study ‘cancer treatment proforma’. This proforma has been ethically approved and used to record the cancer treatment details in the previously mentioned PreFer Study.26

Count data will be collected of the number of PtDAs given to women and health professionals, counts of use and number of clicks on the ‘Cancer, Fertility and Me’ website and downloads of the online PDF version will be recorded. In addition, we will record length of oncology, haematology and fertility consultations and length of time to fertility and cancer treatment. Using count data is a common method for evaluating a decision aid.69

Ethics and dissemination

Ethical considerations

Written, signed consent will be obtained from all participants. Issues particularly pertinent to this study will include participants' right to withdraw from the research process, informed consent and their right to confidentiality and anonymity. Usual NHS care will be provided by the health professionals involved, which includes referral to support and counselling services available within the oncology, haematology and fertility services at the NHS study sites, if any of the women wish. In line with good practice, across both sites, the young women aged 16–17 years and their parents/guardians will be asked to sign for consent.

Dissemination

This research will involve rigorous methods and evaluation in a clinical context.40 The multidisciplinary and collaborative nature of this proposal will enable us to disseminate the research and its milestones to the study participants and into the NHS and wider healthcare community through a variety of local, national and international channels regularly throughout the duration of this research.

During the development and evaluation phases of the research, we are engaging with patients and the public through the North Trent Consumer Research Panel group, NHS England's Patient Involvement Team, International Cancer Patient Voices, the service user

research partnership of Breast Cancer Care as well as presenting our findings at INVOLVE national conferences. A study website is currently under development (http://www.leedsbeckett.ac.uk/cancerfertilityandme.ac.uk).

It will be used to provide an evidence-based portal on the study, team and links with our international partners. It will enable access to the web-based version of the instrument and provide two-way links into other relevant organisations, charities signposted on our webpage and the other social media planned to be used in the study, for example, twitter/blogs. We plan to impact the academic and clinical community more widely through conference presentations and publications in peer-reviewed journals that are open access.

Findings on the quality of the PtDA and study outcomes will be used to provide feedback to health professionals and programme managers. Audit and feedback is an effective intervention for changing the behaviour of health professionals (Cochrane Effective Practice and Organisation of Care Group). The study will be widely and regularly disseminated throughout its duration.

We will develop links with NHS England patient information teams and other UK and international bodies who endorse patient education materials for use/dissemination by service teams. We will also seek assessment by the international criteria of PtDAs to be included in their A to Z inventory.60

The primary output of this study will be the final version of the PtDA. Once evaluated, it will be promoted widely and made available free through a diverse range of media (ie, social and print), charity websites, professional organisations, academic sources and posted to all key stakeholders and participants.

Discussion

It is anticipated that this research will provide evidence about the effectiveness of a PtDA to support cancer patients' decision-making in relation to fertility preservation. Currently, fertility preservation PtDAs for women of reproductive age only exist to support women with breast cancer. A unique feature of this research is that we hope to provide evidence that one open-access PtDA can be used effectively across a range of women's cancer types. Another strength of this research is that it will be administered early into the cancer care pathway, thus providing clinical cancer care teams with an evidence-based resource to provide to all women diagnosed with cancer, therefore meeting a current unmet need. It is anticipated that this will encourage more cancer specialists to have fertility related discussions with women, help raise fertility awareness and provide a resource that will improve the care, support and management of the women.

While this might result in more women choosing to see the fertility expert (Breast Cancer Care alone estimated that around 5000 women per year who should be having this consultation are missing out), it should also reduce the number of women with cancer who are inappropriately referred for fertility preservation and unsuitable for this treatment.

In trying to create a resource that is suitable for women with any cancer, this undoubtedly creates a number of challenges (in terms of synthesising the evidence on cancer treatment on female reproduction and the fertility preservation choices available). We have tried to prepare for this and included an extensive face validity stage during which the PtDA will undergo review from a large number of patients, service users and key stakeholders from a variety of oncology and fertility specialities.

The overall aim of the ‘Cancer, Fertility and Me’ study is to develop and evaluate a new evidence-based PtDA for women with any cancer considering fertility preservation. The data generated as part of this study should help us identify factors associated with its implementation in practice, and/or integration in care. During its evaluation, the cancer care clinical teams will hand out information about the study and the PtDA. We will capture data on the acceptability of this method of integration within care from the clinical teams. It may be our clinical teams think a short skills training session on using our PtDA within cancer and fertility services will support its implementation in usual practice. It is likely future research evaluating our PtDA's impact on health outcomes may therefore also need to include an assessment of shared decision-making training within an implementation study's process evaluation.
