Women's experiences of age-related discontinuation from mammography screening: A qualitative interview study

Randomized Trial of Information for Older Women About Cessation of Breast Cancer Screening Invitations

BACKGROUND

Older women receive no information about why Australia's breast screening program (BreastScreen) invitations cease after 74 years. We tested how providing older women with the rationale for breast screening cessation impacted informed choice (adequate knowledge; screening attitudes aligned with intention).

METHODS

In a three-arm online randomized trial, eligible participants were females aged 70-74 years who had recently participated in breast screening (within 5 years), without personal breast cancer history, recruited through Qualtrics. Participants read a hypothetical scenario in which they received a BreastScreen letter reporting no abnormalities on their mammogram. They were randomized to receive the letter: (1) without any rationale for screening cessation (control); (2) with screening cessation rationale in printed-text form (e.g., downsides of screening outweigh the benefits after age 74); or (3) with screening cessation rationale presented in an animation video form. The primary outcome was informed choice about continuing/stopping breast screening beyond 74 years.

RESULTS

A total of 376 participant responses were analyzed. Compared to controls (n = 122), intervention arm participants (text [n = 132] or animation [n = 122]) were more likely to make an informed choice (control 18.0%; text 32.6%, p = .010; animation 40.5%, p < .001). Intervention arm participants had more adequate knowledge (control 23.8%; text 59.8%, p < .001; animation 68.9%, p < .001), lower screening intentions (control 17.2%; text 36.4%, p < .001; animation 49.2%, p < .001), and fewer positive screening attitudes regarding screening for themselves in the animation arm, but not in the text arm (control 65.6%; text 51.5%, p = .023; animation 40.2%, p < .001).

CONCLUSIONS

Providing information to older women about the rationale for breast cancer screening cessation increased informed decision-making in a hypothetical scenario. This study is an important first step in improving messaging provided by national cancer screening providers direct to older adults. Further research is needed to assess the impact of different elements of the intervention and the impact of providing this information in clinical practice, with more diverse samples.

Breast cancer screening motivation and behaviours of women aged over 75 years

OBJECTIVE

In Australia, breast screening is offered free every two years to women aged 50-74 years. Women aged ≥75 are eligible to receive a free mammogram but do not receive an invitation. This study aimed to explore the motivations and behaviours of women living in Australia aged ≥75 years regarding ongoing breast cancer screening given the public health guidance.

METHODS

Sixty women aged ≥75 were recruited from metropolitan, regional, and rural areas across Australia to participate in a descriptive qualitative study. Semi-structured interviews were used to seek reflection on women's experience of screening, any advice they had received about screening beyond 75, their understanding of the value of screening and their intention to participate in the future. Thematic analysis of transcripts led to the development of themes.

RESULTS

Themes resulting from the study included: reasons to continue and discontinue screening, importance of inclusivity in the health system and availability of information. Regular screeners overwhelmingly wished to continue screening and had strong beliefs in the benefits of screening. Women received limited information about the benefits or harms of screening beyond age 75 and very few had discussed screening with their Primary Healthcare Provider. No longer receiving an invitation to attend screening impacted many women's decision-making.

CONCLUSION

More information via structured discussion with health professionals is required to inform women about the risks and benefits of ongoing screening. No longer being invited to attend screening left many women feeling confused and for some this led to feelings of discrimination.

Screening for cancer beyond recommended upper age limits: views and experiences of older people

BACKGROUND

Internationally, screening programmes and clinical practice guidelines recommend when older adults should stop cancer screening using upper age limits, but it is unknown how older adults view these recommendations.

OBJECTIVE

To examine older adults' views and experiences about continuing or stopping cancer screening beyond the recommended upper age limit for breast, cervical, prostate and bowel cancer.

DESIGN

Qualitative, semi-structured interviews.

SETTING

Australia, telephone.

SUBJECTS

A total of 29 community-dwelling older adults (≥70-years); recruited from organisation newsletters, mailing lists and Facebook advertisements.

METHODS

Interviews were audio-recorded, transcribed and analysed thematically using Framework Analysis.

RESULTS

Firstly, older adults were on a spectrum between trusting recommendations and actively deciding about cancer screening, with some who were uncertain. Secondly, participants reported limited in-depth discussions with health professionals about cancer screening. In primary care, discussions were focused on checking they were up to date with screening or going over results. Discussions mostly only occurred if older adults initiated themselves. Finally, participants had a socially- and self-constructed understanding of screening recommendations and potential outcomes. Perceived reasons for upper age limits were cost, reduced cancer risk or ageism. Risks of screening were understood in relation to their own social experiences (e.g. shared stories about friends with adverse outcomes of cancer treatment or conversations with friends/family about controversy around prostate screening).

CONCLUSIONS

Direct-to-patient information and clinician support may help improve communication about the changing benefit to harm ratio of cancer screening with increasing age and increase understanding about the rationale for an upper age limit for cancer screening programmes.

Long-term psychosocial consequences of false-positive screening mammography: a cohort study with follow-up of 12-14 years in Denmark

OBJECTIVE

To compare the long-term psychosocial consequences of mammography screening among women with breast cancer, normal results and false-positive results.

DESIGN

A matched cohort study with follow-up of 12-14 years.

SETTING

Denmark from 2004 to 2019.

PARTICIPANTS

1170 women who participated in the Danish mammography screening programme in 2004-2005.

INTERVENTION

Mammography screening for women aged 50-69 years.

OUTCOME MEASURES

We assessed the psychosocial consequences with the Consequences Of Screening-Breast Cancer, a condition-specific questionnaire that is psychometrically validated and encompasses 14 psychosocial dimensions.

RESULTS

Across all 14 psychosocial outcomes, women with false-positive results averagely reported higher psychosocial consequences compared with women with normal findings. Mean differences were statistically insignificant except for the existential values scale: 0.61 (95% CI (0.15 to 1.06), p=0.009). Additionally, women with false-positive results and women diagnosed with breast cancer were affected in a dose-response manner, where women diagnosed with breast cancer were more affected than women with false-positive results.

CONCLUSION

Our study suggests that a false-positive mammogram is associated with increased psychosocial consequences 12-14 years after the screening. This study adds to the harms of mammography screening. The findings should be used to inform decision-making among the invited women and political and governmental decisions about mammography screening programmes.

Questioning 'Informed Choice' in Medical Screening: The Role of Neoliberal Rhetoric, Culture, and Social Context

Participation in medical screening programs is presented as a voluntary decision that should be based on an informed choice. An informed choice is often emphasized to rely on three assumptions: (1) the decision-maker has available information about the benefits and harms, (2) the decision-maker can understand and interpret this information, and (3) the decision-maker can relate this information to personal values and preferences. In this article, we empirically challenge the concept of informed choice in the context of medical screening. We use document analysis to analyze and build upon findings and interpretations from previously published articles on participation in screening. We find that citizens do not receive neutral or balanced information about benefits and harms, yet are exposed to manipulative framing effects. The citizens have high expectations about the benefits of screening, and therefore experience cognitive strains when informed about the harm. We demonstrate that decisions about screening participation are informed by neoliberal arguments of personal responsibility and cultural healthism, and thus cannot be regarded as decisions based on individual values and preferences independently of context. We argue that the concept of informed choice serves as a power technology for people to govern themselves and can be considered an implicit verification of biopower.
