A Systematic Review and Meta-Analysis of Interventions to Promote Adjuvant Endocrine Therapy Adherence Among Breast Cancer Survivors.

PURPOSE: Adjuvant endocrine therapy (AET) adherence among breast cancer survivors is often suboptimal, leading to higher cancer recurrence and mortality. Intervention studies to promote AET adherence have burgeoned, more than doubling in number since this literature was last reviewed. The current aim is to provide an up-to-date systematic review and meta-analysis of interventions to enhance AET adherence and to identify strengths and limitations of existing interventions to inform future research and clinical care. METHODS: Systematic searches were conducted in three electronic databases. Studies were included in the systematic review if they examined an intervention for promoting AET adherence among breast cancer survivors. Studies were further included in the meta-analyses if they examined a measure of AET adherence (defined as compliance or persistence beyond initiation) and reported (or provided upon request) sufficient information to calculate an effect size. RESULTS: Of 5,045 unique records, 33 unique studies representing 375,951 women met inclusion criteria for the systematic review. Interventions that educated patients about how to manage side effects generally failed to improve AET adherence, whereas policy changes that lowered AET costs consistently improved adherence. Medication reminders, communication, and psychological/coping strategies showed varied efficacy. Of the 33 studies that met the inclusion criteria for the systematic review, 25 studies representing 367,873 women met inclusion criteria for the meta-analysis. The meta-analysis showed statistically significant effects of the adherence interventions overall relative to study-specified control conditions (number of studies [k] = 25; odds ratio, 1.412; 95% CI, 1.183 to 1.682; P = .0001). Subgroup analyses showed that there were no statistically significant differences in effect sizes by study design (randomized controlled trial v other), publication year, directionality of the intervention (unidirectional v bidirectional contact), or intervention type. CONCLUSION: To our knowledge, this is the first known meta-analysis to demonstrate a significant effect for interventions to promote AET adherence. The systematic review revealed that lowering medication costs and a subgroup of psychosocial and reminder interventions showed the most promise, informing future research, policy, and clinical directions.

A randomized controlled trial of a multi-modal palliative care intervention to promote advance care planning and psychological well-being among adults with advanced cancer: study protocol.

BACKGROUND: Up to half of adults with advanced cancer report anxiety or depression symptoms, which can cause avoidance of future planning. We present a study protocol for an innovative, remotely-delivered, acceptance-based, multi-modal palliative care intervention that addresses advance care planning (ACP) and unmet psychological needs commonly experienced by adults with metastatic cancer. METHODS: A two-armed, prospective randomized controlled trial (RCT) randomizes 240 adults with Stage IV (and select Stage III) solid tumor cancer who report moderate to high anxiety or depression symptoms to either the multi-modal intervention or usual care. The intervention comprises five weekly two-hour group sessions (plus a booster session one month later) delivered via video conferencing, with online self-paced modules and check-ins completed between the group sessions. Intervention content is based on Acceptance and Commitment Therapy (ACT), an acceptance, mindfulness, and values-based model. Participants are recruited from a network of community cancer care clinics, with group sessions led by the network's oncology clinical social workers. Participants are assessed at baseline, mid-intervention, post-intervention, and 2-month follow-up. The primary outcome is ACP completion; secondary outcomes include anxiety and depression symptoms, fear of dying, and sense of life meaning. Relationships between anxiety/depression symptoms and ACP will be evaluated cross-sectionally and longitudinally and theory-based putative mediators will be examined. DISCUSSION: Among adults with advanced cancer in community oncology settings, this RCT will provide evidence regarding the efficacy of the group ACT intervention on ACP and psychosocial outcomes as well as examine the relationship between ACP and anxiety/ depression symptoms. This trial aims to advance palliative care science and inform clinical practice. TRIAL REGISTRATION: Clinicaltrials.gov NCT04773639 on February 26, 2021.

Cancer survivors' cancellations of healthcare appointments during the COVID-19 pandemic: Associations with anxiety and depression.

OBJECTIVE: Though it is well-documented that cancer survivors experienced healthcare delays during the COVID-19 pandemic, who initiated those delays has not been examined. This longitudinal study distinguishes rates of patient-from provider-cancelled healthcare appointments at three timepoints during the pandemic, and examines psychosocial factors associated with patient-cancelled appointments. METHODS: Cancer survivors (N = 147) in the United States completed psychosocial and health behavior measures three times between May and December 2020. We examined rates of patient- and provider-cancelled healthcare appointments, including cancer screening appointments, at each timepoint and change between timepoints. Logistic regression was used to determine if anxiety symptoms, depression symptoms, and COVID-19 fears were associated with self-cancelled healthcare appointments. RESULTS: In May 2020, one third (33.79%) of participants reported one or more self-cancelled appointments within the prior 2 months and nearly half (45.89%) reported one or more provider-cancelled appointments. Rates of provider-cancelled appointments decreased to 35.71% in June/July 2020 and to 9.24% in November/December 2020 (both reflected p < 0.05 reductions compared to the previous timepoint). Rates of self-cancelled appointments, however, remained more stable (ps > 0.144). In June/July and November/December 2020, higher depression and anxiety symptoms, but not COVID-19 fears, were associated with greater likelihood of self-cancelled appointments. CONCLUSIONS: Cancer survivors cancelled their healthcare appointments at a stable rate even as provider-cancelled appointments declined. Depression and anxiety symptoms, but not COVID-19 concerns, were associated with patient cancellations. Interventions that address anxiety and depression symptoms may help to promote adherence to cancer survivorship care during the pandemic.

Randomized Controlled Pilot Trial of a Low-Touch Remotely-Delivered Values Intervention to Promote Adherence to Adjuvant Endocrine Therapy Among Breast Cancer Survivors.

BACKGROUND: Oral anti-cancer treatments such as adjuvant endocrine therapies (AET) for breast cancer survivors are commonly used but adherence is a challenge. Few low-touch, scalable interventions exist to increase ET adherence. PURPOSE: To evaluate the acceptability, feasibility, and initial efficacy of a low-touch, remotely-delivered values plus AET education intervention (REACH) to promote AET adherence. METHODS: A mixed-methods trial randomized 88 breast cancer survivors 1:1 to REACH or Education alone. Wisepill real-time electronic adherence monitoring tracked monthly AET adherence during a 1-month baseline through 6-month follow-up (FU) (primary outcome). Patient-reported outcomes were evaluated through 3- and 6-month FU (secondary). Multiple indices of intervention feasibility and acceptability were evaluated. Qualitative exit interviews (n = 38) further assessed participants' perceptions of feasibility/acceptability and recommendations for intervention adaptation. RESULTS: The trial showed strong feasibility and acceptability, with an eligible-to-enrolled rate of 85%, 100% completion of the main intervention sessions, and "good" intervention satisfaction ratings on average. For Wisepill-assessed AET adherence, REACH outperformed Education for Month 1 of FU (p = .027) and not thereafter. Participants in REACH maintained high adherence until Month 4 of FU, whereas in Education, adherence declined significantly in Month 1. Conditions did not differ in self-reported adherence, positive affective attitudes, future intentions, or necessity beliefs. REACH trended toward less negative AET attitudes than Education at 3-month FU (p = .057) reflecting improvement in REACH (p = .004) but not Education (p = .809). Exploratory moderator analyses showed that average to highly positive baseline AET affective attitudes and oncologist-patient communication each predicted higher adherence following REACH than Education; low levels did not. Participants identified recommendations to strengthen the interventions. CONCLUSIONS: REACH, a low-touch values intervention, showed good feasibility and acceptability, and initial promise in improving objectively-assessed AET adherence among breast cancer survivors (relative to education alone). Future research should target improving REACH's tailoring and endurance.

Cancer survivors' perceived vulnerability to COVID-19 and impacts on cognitive, affective, and behavioral responses to the pandemic.

STUDY OBJECTIVES: Given the uncertainty COVID-19 has caused for individuals with prior medical conditions, we examined the extent to which cancer survivors consider themselves at risk for the global COVID-19 pandemic (henceforth COVID), both in general and due to their cancer history. Additionally, we evaluated whether perceived vulnerability to COVID among cancer survivors predicts their cognitive/affective and behavioral responses to the pandemic. DESIGN/SAMPLE: Cancer survivors who completed primary cancer treatment (median months since treatment = 33.00) and were enrolled in prior behavioral trials with our research team (N = 146) completed two surveys in May-July 2020 (95.89% retention). METHODS: Participants rated perceived next-year risk of infection and of dying from COVID. We adapted established scales to assess perceived vulnerability to COVID generally versus as a cancer survivor, catastrophizing about possible COVID symptoms, COVID-related contamination fears, and adherence to COVID prevention behaviors. FINDINGS: In May 2020, on a 1-100 scale with 0 = no chance and 100 = definitely will occur, cancer survivors reported a chance in the next year of contracting COVID of M = 39.94 (SD = 23.90), and dying from COVID of M = 24.46 (SD = 24.84). Cancer survivors reported somewhat greater vulnerability to COVID compared to same-aged peers, increased contamination fears, and high adherence to COVID prevention measures. Similar findings emerged six weeks later, suggesting stability over time. In simple linear regression models, both general and cancer survivor-specific perceived COVID vulnerability predicted COVID symptom catastrophizing and contamination fears; in multivariable models, only general vulnerability remained a significant predictor. General perceived vulnerability and contamination fears predicted greater adherence to COVID prevention behaviors. CONCLUSIONS: Cancer survivors perceived elevated vulnerability to COVID even years after treatment, which predicted adherence to COVID prevention behaviors. Future research should identify the optimal balance between supporting cancer survivors' concerns and minimizing negative impacts on quality of life.

Retrospective evaluation of a clinical decision support tool for effective computed tomography angiography utilization in urgent brain imaging of suspected TIA/minor stroke in the emergency department.

OBJECTIVES: The Canadian Stroke Best Practice Recommendations suggests that patients suspected of transient ischemic attack (TIA)/minor stroke receive urgent brain imaging, preferably computed tomography angiography (CTA). Yet, high requisition rates for non-cerebrovascular patients overburden limited radiological resources, putting patients at risk. We hypothesize that our clinical decision support tool (CDST) developed for risk stratification of TIA in the emergency department (ED), and which incorporates Canadian guidelines, could improve CTA utilization. METHODS: Retrospective study design with clinical information gathered from ED patient referrals to an outpatient TIA unit in Victoria, BC, from 2015-2016. Actual CTA orders by ED and TIA unit staff were compared to hypothetical CTA ordering if our CDST had been used in the ED upon patient arrival. RESULTS: For 1,679 referrals, clinicians ordered 954 CTAs. Our CDST would have ordered a total of 977 CTAs for these patients. Overall, this would have increased the number of imaged-TIA patients by 89 (10.1%) while imaging 98 (16.1%) fewer non-cerebrovascular patients over the 2-year period. Our CDST would have ordered CTA for 18 (78.3%) of the recurrent stroke patients in the sample. CONCLUSIONS: Our CDST could enhance CTA utilization in the ED for suspected TIA patients, and facilitate guideline-based stroke care. Use of our CDST would increase the number of TIA patients receiving CTA before ED discharge (rather than later at TIA units) and reduce the burden of imaging stroke mimics in radiological departments.
