The experience of making treatment decisions for women with early stage breast cancer: a diagrammatic representation

A special kind of stress: Assessing feelings of decisional distress for breast cancer treatment decisions

OBJECTIVE

Women with breast cancer need to make difficult treatment decisions and may experience decisional distress (worry, anxiety, and thought intrusion) associated with these decisions. This study investigated ways that decisional distress was both associated with and distinct from other variables regarding decisional process and life functioning, and it investigated the validity of a decisional distress scale.

METHODS

A total of 263 women previously or currently diagnosed with breast cancer reported on initial treatment decisions regarding surgery, chemotherapy, or radiation, or decisions involving oral endocrine therapy (either currently or retrospectively). Participants completed online measures of decisional distress, alliance and confusion in patient-practitioner relationships, positive and negative interactions in close relationships, financial and general distress, and decision satisfaction.

RESULTS

Decisional distress demonstrated a unidimensional factor structure invariant across treatment context groups, a wide range of meaningful variation, significant correlations with all hypothesized variables (especially patient confusion), but also key distinctions from other variables.

CONCLUSION

Decisional distress is a meaningful construct that can be assessed with precision, and important for understanding medical decision-making processes and patient quality of life.

PRACTICE IMPLICATIONS

Assessing decisional distress is crucial for evaluating treatment decision outcomes. One key to reducing decisional distress may involve reducing patient confusion.

Surgical treatment choices for breast cancer in Newfoundland and Labrador: a retrospective cohort study

BACKGROUND

Mastectomy is often chosen by women for treatment of breast cancer, even when breast-conserving surgery (BCS) is an option. Newfoundland and Labrador has a high mastectomy rate. We documented the number of breast cancers over a given period in the province and their related surgical treatments, and explored the impact of several variables on surgical choice.

METHODS

A retrospective cohort design linked diagnosis data from the Newfoundland and Labrador tumour registry to surgery data from the Canadian Institute for Health Information Discharge Abstract Database. Data were extracted for all women aged 19 years or more in whom breast cancer was diagnosed in 2009-2014.

RESULTS

A total of 2346 cases of breast cancer with a linked surgical procedure were included. Most operations (1605 [68.4%]) were mastectomy procedures, with the remainder being BCS. Logistic regression analysis revealed that women were 1.82 times (95% confidence interval [CI] 1.64-2.02) more likely to have mastectomy for each unit of stage increase from 0 to IV and 1.15 times (95% CI 1.11-1.21) more likely for each unit of driving time increase.

CONCLUSION

Tumour stage and driving time to a radiation facility significantly predicted Newfoundland and Labrador women's surgical treatment choices for breast cancer. Notably, mastectomy was the favoured choice across all age groups, tumour stages and geographical regions of the province. We hope that these results will galvanize efforts to better understand local surgical practices and assist in improving the quality of surgical care of women with breast cancer.

Factors influencing surgical treatment decisions for breast cancer: a qualitative exploration of surgeon and patient perspectives

Background

The rate of mastectomy is much higher in Newfoundland and Labrador than in any other province in Canada, even for women diagnosed at an early stage. In this paper, we present qualitative data from women who have made a decision for surgical treatment and from breast surgeons in an effort to better explicate factors influencing breast cancer (bca) surgical decision-making.

Methods

The study's descriptive, qualitative design involved holding interviews with breast surgeons and holding focus groups and interviews with women who were offered the choice of breast-conserving surgery (bcs) or mastectomy (mt).

Results

Participants included 35 women and 13 surgeons. High interest in mt and increasing requests for prophylactic contralateral mt were evident. A host of factors-clinical, demographic, psychosocial, education-related, and cultural-influenced the decisions. A key factor for women was fear of recurrence and a need to "just get rid of it," but the experiences of others also influenced the decisions. Life stage and family considerations also factored prominently into women's decisions.

Conclusions

Women with early-stage bca more often chose mt and often demanded prophylactic removal of the healthy breast. Findings highlight the importance of ensuring that women at average risk are appropriately counselled about the low likelihood of a subsequent contralateral bca and the lack of survival benefit associated with prophylactic contralateral mt. Findings also revealed other areas of presurgical discussion that might help women think through their personal circumstances and values so as to encourage informed surgical decisions.

From the conventional to the alternative: exploring patients' pathways of cancer treatment and care

BACKGROUND

Complementary and alternative medicine (CAM) use is widespread and on the increase among cancer patients. Most research to date has involved a cross-sectional snapshot of CAM use rather than an exploration into the longitudinal, nonlinear treatment trajectories that cancer patients develop. Our aim is to explore and describe different treatment and decision-making pathways that individuals develop after receipt of a diagnosis of either breast, colorectal, or prostate cancer.

METHODS

The study was part of a larger mixed-methods pilot project to explore the feasibility of conducting a five-year international study to assess cancer patients' treatment pathways, including health care use and the perceived impact of different patterns of use on health outcomes over the course of one year. The results presented in this paper are based on the analysis of personal interviews that were conducted over the course of 12 months with 30 participants.

RESULTS

Five pathways emerged from the data: passive conventional, self-directed conventional, cautious integrative, aggressive integrative, and aggressive alternative. Factors that shaped each pathway included health beliefs, decision-making role, illness characteristics, and the patient-practitioner relationship.

CONCLUSIONS

The results of this examination of the longitudinal treatment and decision-making trajectory provide important information to support health care professionals in their quest for individualized, targeted support at each stage of the patient pathway.

Development and psychometric properties of a brief measure of subjective decision quality for breast cancer treatment

Background

Breast cancer patients face several preference-sensitive treatment decisions. Feelings such as regret or having had inadequate information about these decisions can significantly alter patient perceptions of recovery and recurrence. Numerous objective measures of decision quality (e.g., knowledge assessments, values concordance measures) have been developed; there are far fewer measures of subjective decision quality and little consensus regarding how the construct should be assessed. The current study explores the psychometric properties of a new subjective quality decision measure for breast cancer treatment that could be used for other preference sensitive decisions.

Methods

320 women aged 20–79 diagnosed with AJCC stage 0 – III breast cancer were surveyed at two cancer specialty centers. Decision quality was assessed with single items representing six dimensions: regret, satisfaction, and fit as well as perceived adequacy of information, time, and involvement. Women rated decision quality for their overall treatment experience and surgery, chemotherapy, and radiation decisions separately. Principle components was used to explore factor structure. After scales were formed, internal consistency was computed using Cronbach’s alpha. The association of each of the four final scales with patient characteristics scores was examined by Pearson correlation.

Results

For overall breast cancer treatment as well as surgery, chemotherapy, and radiation decisions, the six items yielded a single factor solution. Factor loadings of the six decision items were all above .45 across the overall and treatment-specific scales, with the exception of “Right for You” for chemotherapy and radiation. Internal consistency was 0.77, 0.85, 0.82, and 0.78 for the overall, surgery, chemotherapy, and radiation decision quality scales, respectively.

Conclusions

Our measure of subjective appraisal of breast cancer treatment decisions includes 5 related elements; regret and satisfaction as well as perceived adequacy of information, time, and involvement. Future research is needed to establish norms for the measure as is further psychometric testing, particularly to examine how it is associated with outcomes such as quality of life, psychological coping and objective decision quality.

Factors influencing the surgery intentions and choices of women with early breast cancer: the predictive utility of an extended theory of planned behaviour

Background

Women diagnosed with early breast cancer (stage I or II) can be offered the choice between mastectomy or breast conservation surgery with radiotherapy due to equivalence in survival rates. A wide variation in the surgical management of breast cancer and a lack of theoretically guided research on this issue highlight the need for further research into the factors influencing women’s choices. An extended Theory of Planned Behaviour (TPB) could provide a basis to understand and predict women’s surgery choices. The aims of this study were to understand and predict the surgery intentions and choices of women newly diagnosed with early breast cancer, examining the predictive utility of an extended TPB.

Methods

Sixty-two women recruited from three UK breast clinics participated in the study; 48 women, newly diagnosed with early breast cancer, completed online questionnaires both before their surgery and after accessing an online decision support intervention (BresDex). Questionnaires assessed views about breast cancer and the available treatment options using items designed to measure constructs of an extended TPB (i.e., attitudes, subjective norms, perceived behavioural control, and anticipated regret), and women’s intentions to choose mastectomy or BCS. Objective data were collected on women’s choice of surgery via the clinical breast teams. Multiple and logistic regression analyses examined predictors of surgery intentions and subsequent choice of surgery.

Results

The extended TPB accounted for 69.9% of the variance in intentions (p <.001); attitudes and subjective norms were significant predictors. Including additional variables revealed anticipated regret to be a more important predictor than subjective norms. Surgery intentions significantly predicted surgery choices (p <.01).

Conclusions

These findings demonstrate the utility of an extended TPB in predicting and understanding women’s surgery intentions and choices for early breast cancer. Understanding these factors should help to identify key components of interventions to support women while considering their surgery options.

A qualitative study of breast cancer treatment decisions: evidence for five decision-making styles

Being diagnosed with breast cancer requires that women make a number of decisions about their medical treatments. To gain insight into the variety of forces that shape a woman's breast cancer treatment decisions, we conducted semistructured interviews with 44 breast cancer survivors. Through an interpretive analysis, we identified five treatment decision-making styles: (a) medical expert, (b) self-efficacy, (c) relationship embedded, (d) inhibition, and (e) constellation of information, which are differentiated by two dimensions: (a) low versus high information needs and (b) self versus other preferences.

Increasing readiness to decide and strengthening behavioral intentions: evaluating the impact of a web-based patient decision aid for breast cancer treatment options (BresDex: www.bresdex.com)

OBJECTIVES

To undertake a quantitative evaluation of a theory-based, interactive online decision aid (BresDex) to support women choosing surgery for early breast cancer (Stage I and II), based on observations of its use in practice.

METHODS

Observational cohort study. Website log-files collected data on the use of BresDex. Online questionnaires assessed knowledge about breast cancer and treatment options, degree to which women were deliberating about their options, and surgery intentions, pre- and post-BresDex.

RESULTS

Readiness to make a decision significantly increased after using BresDex (p<.001), although there was no significant improvement in knowledge. Participants that were 'less ready' to make a decision before using BresDex, spent a longer time using BresDex (p<.05). Significant associations between surgery intentions and choices were observed (p<.001), with the majority of participants going on to have BCS. Greater length of time spent on BresDex was associated with stronger intentions to have BCS (p<.05).

CONCLUSION

The use of BresDex appears to facilitate readiness to make a decision for surgery, helping to strengthen surgery intentions.

PRACTICE IMPLICATIONS

BresDex may prove a useful adjunct to the support provided by the clinical team for women facing surgery for early breast cancer.

Theory-based design and field-testing of an intervention to support women choosing surgery for breast cancer: BresDex

OBJECTIVE

Design and undertake usability and field-testing evaluation of a theory-guided decision aid (BresDex) in supporting women choosing surgery for early breast cancer.

METHODS

An extended Theory of Planned Behavior (TPB) and the Common Sense Model of Illness Representations (CSM) guided the design of BresDex. BresDex was evaluated and refined across 3 cycles by interviewing 6 women without personal history of breast cancer, 8 women with personal history of breast cancer who had completed treatment and 11 women newly diagnosed with breast cancer. Participants were interviewed for views on content, presentation (usability) and perceived usefulness towards deciding on treatment (utility). Framework analysis was used, guided by the extended TPB and the CSM.

RESULTS

BresDex was positively received in content and presentation (usability). It appeared an effective support to decision-making and useful source for further information, particularly in clarifying attitudes, social norms and perceived behavioral control, and presenting consequences of decisions (utility).

CONCLUSION

This study illustrates the potential benefit of the extended TPB and CSM in designing a decision aid to support women choosing breast cancer surgery.

PRACTICE IMPLICATIONS

BresDex could provide decision-making support and serve as an additional source of information, to complement the care received from the clinical team.

Understanding surgery choices for breast cancer: how might the Theory of Planned Behaviour and the Common Sense Model contribute to decision support interventions?

OBJECTIVE

To describe the evidence about factors influencing breast cancer patients' surgery choices and the implications for designing decision support in reference to an extended Theory of Planned Behaviour (TPB) and the Common Sense Model of Illness Representations (CSM).

BACKGROUND

A wide range of factors are known to influence the surgery choices of women diagnosed with early breast cancer facing the choice of mastectomy or breast conservation surgery with radiotherapy. However, research does not always reflect the complexities of decision making and is often atheoretical. A theoretical approach, as provided by the CSM and the TPB, could help to identify and tailor support by focusing on patients' representations of their breast cancer and predicting surgery choices.

DESIGN

Literature search and narrative synthesis of data.

SYNTHESIS

Twenty-six studies reported women's surgery choices to be influenced by perceived clinical outcomes of surgery, appearance and body image, treatment concerns, involvement in decision making and preferences of clinicians. These factors can be mapped onto the key constructs of both the TPB and CSM and used to inform the design and development of decision support interventions to ensure accurate information is provided in areas most important to patients.

CONCLUSIONS

The TPB and CSM have the potential to inform the design of decision support for breast cancer patients, with accurate and clear information that avoids leading patients to make decisions they may come to regret. Further research is needed examining how the components of the extended TPB and CSM account for patients' surgery choices.

Fit and misfit

This article presents an interpretive case analysis of an older adult's experience with treatment decision making for acute myeloid leukemia. Interview and observational data were compared and contrasted with key constructs in behavioral decision theory to analyze theoretical utility and fit. Decision making involved a complex interplay among the patient, treating clinicians, and family members. While some constructs of decision theory, such as trade-offs, avoidance-avoidance, and the certainty effect, showed utility for decision making in geriatric oncology, this case demonstrated that individual preferences for treatment may be expressed in quality of life preferences rather than a specific treatment decision. The Cage, a major theme in this case, represented the trap of two undesirable choices in treatment decision making, as well as the imprisoning consequence of aggressive medical treatment for advanced cancer. Further decision making research is needed to develop practice-level theory that can more effectively support and guide treatment decision making in geriatric oncology.

Development of decision-support intervention for Black women with breast cancer

BACKGROUND

Adjuvant therapy improves breast cancer survival but is underutilized by Black women. Few interventions have addressed this problem. This preliminary report describes the process we used to develop a decision-support intervention for Black women eligible for adjuvant therapy. Aims were to use qualitative methods to describe factors that influence Black women's adjuvant therapy decisions, use these formative data to develop messages for a treatment decision-support intervention, and pilot test the acceptability and utility of the intervention with community members and newly diagnosed women.

METHODS

Thirty-four in-depth interviews were conducted with breast cancer patients in active treatment, survivors and cancer providers to gather qualitative data. Participant ages ranged from 38 to 69 years. A cultural framework was used to analyze the data and to inform intervention messages. Most women relied on their providers for treatment recommendations. Several women reported problems communicating with providers and felt unprepared to ask questions and discuss adjuvant treatment options. Other factors related to treatment experiences were: spiritual coping, collectivism and sharing breast cancer experiences with other Black survivors.

RESULTS

Using these formative data, we developed an intervention that is survivor-based and includes an in-person session which incorporates sharing personal stories, communication skills training and decision support. Intervention materials were reviewed by community members, researchers/clinicians and patients newly diagnosed with breast cancer.

CONCLUSION

Patients reported satisfaction with the intervention and felt better prepared to talk with providers. The intervention will be tested in a randomized trial to enhance decision support and increase use of indicated adjuvant treatment.

The phenomenon of making decisions during the experience of early breast cancer

Breast cancer patients are faced with many decisions about their treatment, relationships and lives. The aims of this study were: to provide an understanding of the phenomenon of making decisions during the experience of early breast cancer, and to describe the types of decisions these patients are typically faced with. Previous research has focused largely on describing the different ways patients behave when making choices about treatment. However, few studies provide an understanding of the range of decisions women are likely to face, or describe what the experience of making these decisions is like. Hermeneutic phenomenology was used to inform the research. In-depth interviews were conducted with 18 breast cancer patients who had completed treatment. This study provides an understanding of the broad range of decisions with which women may be faced, and presents a new interpretation of what the experience of making decisions is like for women diagnosed with breast cancer. Five existential themes were found to be representative of the experience of making decisions: being challenged, getting ready, surviving, sharing the challenge and interrogating the future. Health professionals can use the understandings presented to improve their therapeutic relationships with patients and further assist women as they work through their experience of breast cancer.
