"Now at least we have something to call it": Patient and care partner experiences receiving an amyloid PET scan

Persons With Cognitive Impairment and Care Partner Motivations and Experiences of Undergoing an Amyloid Scan: A Systematic Review of Qualitative Studies

BACKGROUND AND OBJECTIVES

Amyloid positron emission tomography scans can enhance the accuracy of dementia diagnoses. However, the perspectives and experiences of people with cognitive impairment and their care partners undergoing an amyloid scan are less well understood. Therefore, this review aimed to identify and summarize qualitative studies exploring patient and care partner experiences of undergoing an amyloid scan.

RESEARCH DESIGN AND METHODS

We searched Embase, MEDLINE, and PsychInfo in March 2024. Articles were screened for inclusion by 2 reviewers and critically appraised using the Joanna Briggs Institute Critical Appraisal Tool for Qualitative Studies. Data from the included studies were synthesized using thematic synthesis.

RESULTS

We identified 10 papers from 6 studies. We identified 4 themes: (1) motivations for undergoing an amyloid scan, (2) experiences of receiving the result, (3) emotional responses to the result, and (4) actions in light of the scan result. Participants reported undergoing the scan to determine the cause of cognitive impairment. They described the information gained from the scan as helpful but struggled to recall the correct terminology or implications of the scan. Emotional responses to the scan varied depending on the scan result. In light of the scan result, the most common action was making advanced plans; however, this was mainly discussed among participants with elevated amyloid.

DISCUSSIONS AND IMPLICATIONS

Amyloid scans can provide useful and actionable information. However, learning the scan result could be distressing. Future research is needed to balance the potential benefits and harms of amyloid scans.

"There has to be more caring": patient and care partner experiences of the disclosure of amyloid-β PET scan results

OBJECTIVES

To explore patient and care partner experiences of receiving an amyloid scan result, with a focus on how clinician disclosure practices influenced patient and care partner emotional responses to the scan result and/or diagnosis.

METHODS

Semi-structured interviews with 38 people with mild cognitive impairment or dementia and 62 care partners who experienced the disclosure of results from an amyloid PET scan as part of the CARE-IDEAS study. We used thematic analysis to analyze interview transcripts.

RESULTS

We identified four aspects of the disclosure process that could influence patient and care partner emotional experiences of the scan result/diagnosis: (1) mode of delivery, (2) presence of a care partner, (3) clarity of the scan result explanation, and (4) discussion of post-scan treatment and support options.

CONCLUSIONS

Emotional experiences of an amyloid scan result can vary depending on how results are communicated. These findings support previous efforts to develop standard disclosure protocols. Scan results should be delivered in person with the care partner present. Clinicians should give a clear explanation of the result and its implications in an empathetic manner. Options for treatment and support should be discussed for all patients.

Towards an improved dementia care experience in clinical radiography practice: A state-of-the-art review

INTRODUCTION

The increasing global incidence rate of dementia and associated co/multimorbidity has consequently led to a rise in the number of people with dementia (PwD) requiring clinical radiography care services. This review aims to explore and integrate findings from diverse settings with a focus on the experiences of PwD and stakeholders, towards the development of a holistic approach for dementia care and management within the context of radiography services.

METHOD

An electronic search was performed across the following databases: PUBMED, CINAHL, Medline, SCOPUS, and ScienceDirect for articles published from January 2009 and June 2023. Articles were included if they fulfilled a predefined criteria mainly focused on experiences of PwD and/or other stakeholders when using the radiography services. Data obtained from the included studies were analysed using a result-based convergent synthesis.

RESULT

Eleven studies from diverse settings met the inclusion criteria. A mix of both positive and negative experiences of PwD and stakeholders were reported following visits to radiology and radiotherapy departments were highlighted across settings. The findings were themed around the need for: person-centred care, effective communication, attitudinal changes of staff, specialised and improved clinical environment and inclusion of caregivers for the care of PwD.

DISCUSSION

This study emphasise the critical importance of adopting holistic approaches to caring for PwD. This involves adopting a person-centred approach, actively involving caregivers, effective communication, and adequate training for radiographers to provide quality services, all in dementia-friendly environments.

CONCLUSION

The experiences of various stakeholders highlight the need for a more holistic approach and strategy for the care and management of PwD within the context of the radiography services. This calls for an urgent need for a comprehensive strategy that includes awareness creation of staff to enhance the quality of care and the overall experience for PwD using the radiography services.

Beta amyloid PET scans for dementia diagnoses: Practice and research implications from CARE-IDEAS

Beta amyloid PET scans are a minimally invasive biomarker that may inform Alzheimer's disease (AD) diagnosis. The Caregiver's Reactions and Experience (CARE) study, an IDEAS supplement, aimed to understand experiences of PET scan recipients and their care partners regarding motivations for scans, reporting and interpreting results, and impact of results. Patients with mild cognitive impairment or dementia who agreed to join the CARE-IDEAS study and their care partners participated in a baseline survey and follow-up survey approximately 18 months later, supplemented by in-depth qualitative interviews with subsets of participants. Patients who received scans and volunteered for follow-up research were more likely to be male, better educated, and have higher income than the general population. Survey information was merged with Medicare data. This article integrates findings from several CARE-IDEAS publications and provides implications for practice and research. Although most participants accurately reported scan results, they were often confused about their meaning for prognosis. Some participants reported distress with results, but there were no significant changes in measured depression, burden, or economic strain over time. Many respondents desired more information about prognosis and supportive resources. Scan results were not differentially associated with changes in service use over time. Findings suggest a need for carefully designed and tested tools for clinicians to discuss risks and benefits of scans and their results, and resources to support patients and care partners in subsequent planning. Learning of scan results provides a point-of-contact that should be leveraged to facilitate shared decision-making and person-centered longitudinal AD care.

Advance directives among cognitively impaired persons who had an amyloid PET scan and their care partners: a mixed-methods study

BACKGROUND

Little research exists on the role of β-amyloid PET scans as part of Alzheimer's diagnostic tests and documentation of end-of-life preferences for persons with cognitive impairment. The study objectives were to examine the association of amyloid PET scan results (elevated vs. not elevated amyloid levels) and diagnostic category (mild cognitive impairment vs. dementia) with the likelihood of having an advance directive (reported a median of 4.5 months post-scan); to explore perceptions of PET scan results and their influence on planning for the future among persons with cognitive impairment and their care partners.

METHODS

Sequential, explanatory mixed-methods design using data from dyads in the CARE-IDEAS study: advance directives as a factor of diagnostic category and scan result using multivariable logistic regression models; thematic analysis of semi-structured interviews with persons with cognitive impairment and care partners to explore how scan results influenced documentation of future healthcare preferences. Participants included 1784 persons with cognitive impairment and care partners from the CARE-IDEAS study, and a subsample of 100 semi-structured telephone interviews.

RESULTS

81.6% of dyads reported an advance directive. Non-Hispanic, White participants had higher rates of advance directives. There was no significant association between having an advance directive and scan results. Qualitative analysis provided insight into perceived urgency to have advance directives, evolving healthcare preferences, and the context of completing advance directives.

CONCLUSIONS

Although amyloid PET scans prompted persons with cognitive impairment and care partners to consider progressive cognitive impairment as part of evolving healthcare preferences, we found substantial variability in the perceived urgency of documentation.
