Psychosocial and clinical predictors of continued cancer screening in older adults

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.

Assessment of the Psychosocial Impact of Pancreatic Cancer Surveillance in High-Risk Individuals

OBJECTIVES

Pancreatic cancer (PC) surveillance of high-risk individuals (HRIs) downstages PC and improves survival. However, it remains less clear whether PC surveillance has a positive psychosocial impact on HRIs. Herein, we aimed to define the attitudes and beliefs of HRIs undergoing PC surveillance, and the immediate and sustained psychosocial impact of PC surveillance in HRIs.

METHODS

100 HRIs undergoing PC surveillance by endoscopic ultrasound (EUS) completed three surveys addressing different components of the psychosocial impact of PC surveillance. Logistic regression analyses were performed to identify predictive factors relating to these components.

RESULTS

Most HRIs reported increased perceived benefits of PC surveillance, self-efficacy, and perceived severity of PC. HRIs reported few negative emotions prior to surveillance and frequent positive emotions after surveillance. Compared to prior to surveillance, there was a 53.5% decrease in the level of distress reported by HRIs after surveillance, which was sustained for 4-6 weeks post-surveillance. Family history of PC and lower self-reported mental health were identified as predictors for increased perceived susceptibility to PC (p < 0.01) and greater change in distress pre- to post-surveillance (p < 0.01), respectively.

CONCLUSIONS

Our findings suggest that PC surveillance can lead to sustained psychosocial benefits in HRIs.

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.

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

INTRODUCTION

In Denmark, women are discontinued from mammography screening at age 69 due to decreased likelihood of benefits and increased likelihood of harm. The risk of harm increases with age and includes false positives, overdiagnosis and overtreatment. In a questionnaire survey, 24 women expressed unsolicited concerns about being discontinued from mammography screening due to age. This calls for further investigation of experiences related to discontinuation from screening.

METHODS

We invited the women, who had left comments on the questionnaire, to participate in in-depth interviews with the purpose to explore their reactions, preferences, and conceptions about mammography screening and discontinuation. The interviews lasted 1-4 h and were followed up with a telephone interview 2 weeks after the initial interview.

RESULTS

The women had high expectations of the benefits of mammography screening and felt that participation was a moral obligation. Following that, they perceived the screening discontinuation as a result of societal age discrimination and consequently felt devalued. Further, the women perceived the discontinuation as a health threat, felt more susceptible to late diagnosis and death, and therefore sought out new ways to control their risk of breast cancer.

CONCLUSION

Our findings indicate that the age-related discontinuation from mammography screening might be of more importance than previously assumed. This study raises important questions about screening ethics, and we encourage research to explore this in other settings.

PATIENT AND PUBLIC CONTRIBUTION

This study was conducted as a result of the women's unsolicited concerns about being discontinued from screening. This particular group contributed to the study with their own statements, interpretations and perspectives on the discontinuation of screening, and the initial analysis of data was discussed with the women during follow-up interviews.

General practitioners' views and experiences of communicating with older people about cancer screening: a qualitative study

BACKGROUND

Older adults should be supported to make informed decisions about cancer screening. However, it is unknown how general practitioners (GPs) in Australia communicate about cancer screening with older people.

AIM

To investigate GPs' views and experiences of communicating about cancer screening (breast, cervical, prostate, and bowel) with older people (≥70 years).

DESIGN AND SETTING

Qualitative, semi-structured interviews, Australia.

METHOD

Interviews were conducted with GPs practising in Australia (n = 28), recruited through practice-based research networks, primary health networks, social media, and email invitation. Interviews were audio-recorded and analysed thematically using Framework Analysis.

RESULTS

Findings across GPs were organized into 3 themes: (i) varied motivation to initiate cancer screening discussions; some GPs reported that they only initiated screening within recommended ages (<75 years), others described initiating discussions beyond recommended ages, and some experienced older patient-initiated discussions; (ii) GPs described the role they played in providing screening information, whereby detailed discussions about the benefits/risks of prostate screening were more likely than other nationally funded screening types (breast, cervical, and bowel); however, some GPs had limited knowledge of recommendations and found it challenging to explain why screening recommendations have upper ages; (iii) GPs reported providing tailored advice and discussion based on personal patient preferences, overall health/function, risk of cancer, and previous screening.

CONCLUSIONS

Strategies to support conversations between GPs and older people about the potential benefits and harms of screening in older age and rationale for upper age limits to screening programmes may be helpful. Further research in this area is needed.

Factors associated with women's supplemental screening intentions following dense breast notification in an online randomised experimental study

Controversy surrounding recommendations for supplemental screening (ultrasound and magnetic resonance screening) in women with dense breasts exists, as the long-term benefits from these additional modalities may not outweigh the harms. This study aimed to examine factors associated with supplemental screening intentions following a hypothetical breast density notification in a population of women who have not been routinely notified. Australian women of breast screening age participated in an online randomised experimental study where they were presented with one of two breast density notifications (with or without health literacy-sensitive information) and asked their screening intentions. After adjusting for covariates in multivariable analyses, women in both groups (n = 940) who indicated higher levels of breast cancer worry, had private health insurance, had a family history of breast cancer, and had a greater number of times previously attending mammography screening had higher intentions for supplemental screening. Understanding women's supplemental screening intentions following notification of dense breasts has important implications for health systems with breast screening considering the impacts of widespread notification. Personal, clinical and psychological factors should be considered when discussing both the benefits and harms of supplemental screening with women with dense breasts.

Feasibility and Acceptability of Personalized Breast Cancer Screening (DECIDO Study): A Single-Arm Proof-of-Concept Trial

The aim of this study was to assess the acceptability and feasibility of offering risk-based breast cancer screening and its integration into regular clinical practice. A single-arm proof-of-concept trial was conducted with a sample of 387 women aged 40-50 years residing in the city of Lleida (Spain). The study intervention consisted of breast cancer risk estimation, risk communication and screening recommendations, and a follow-up. A polygenic risk score with 83 single nucleotide polymorphisms was used to update the Breast Cancer Surveillance Consortium risk model and estimate the 5-year absolute risk of breast cancer. The women expressed a positive attitude towards varying the frequency of breast screening according to individual risk and, especially, more frequently inviting women at higher-than-average risk. A lower intensity screening for women at lower risk was not as welcome, although half of the participants would accept it. Knowledge of the benefits and harms of breast screening was low, especially with regard to false positives and overdiagnosis. The women expressed a high understanding of individual risk and screening recommendations. The participants' intention to participate in risk-based screening and satisfaction at 1-year were very high.
