Patient and family financial burden associated with cancer treatment in Canada: a national study

Timeliness of Health Technology Assessments and Price Negotiations for Oncology Drugs in Canada

Purpose

To evaluate whether time targets for Canadian Agency for Drugs and Technologies in Health (CADTH) reimbursement reviews and pan-Canadian Pharmaceutical Alliance (pCPA) price negotiations are being achieved for oncology drugs.

Materials and Methods

Recommendations, dates of submission and publication, and indications for oncology medicines issued between January 2014 and December 2023 were recorded from CADTH's reimbursement reports webpage. The date any negotiation began and the date it was completed (successfully or not), or when a decision was made not to pursue negotiation was extracted from the pCPA's webpage. The duration of each CADTH review and pCPA negotiation was calculated, together with time between CADTH's recommendation and start of the pCPA negotiation or a decision not to negotiate. Percentages of reviews completed within CADTH's target and of times taken by the pCPA to decide whether to negotiate and by its price negotiations completed within the relevant targets were calculated.

Results

CADTH achieved its 270-days target in 88.2% to 100% of reviews issued between 2015 and 2019 but only in 65.9% to 73.1% of reviews issued in the last three years of the decade. CADTH's "typical timeline" of 180 days was achieved in under 40% of reviews issued in 2015 and not attained in any review in 2021, 2022 or 2023. The pCPA's target of 60 days for deciding whether to negotiate was achieved for all recommendations issued in 2014 but dropped below 40% for the last seven years of the decade; its target of 130 days for negotiations was achieved for over 85% of the recommendations in 2014 but decreased to only 14.3% in 2016 and then gradually increased to 61.5% in 2023.

Conclusion

CADTH's "typical timeline" and the pCPA's targets were not met sufficiently to be meaningful. Their processes take too long for cancer drugs.

Patient and Family Financial Burden in Cancer: A Focus on Differences across Four Provinces, and Reduced Spending Including Decisions to Forego Care in Canada

GOAL

This study aimed to examine provincial differences in patient spending for cancer care and reductions in household spending including decisions to forego care in Canada.

METHODS

Nine-hundred and one patients with cancer, from twenty cancer centers across Canada, completed a self-administered questionnaire (P-SAFE version 7.2.4) (344 breast, 183 colorectal, 158 lung, and 216 prostate) measuring direct and indirect costs and spending changes.

RESULTS

Provincial variations showed a high mean out-of-pocket cost (OOPC) of CAD 938 (Alberta) and a low of CAD 280 (Manitoba). Differences were influenced by age and income. Income loss was highest for Alberta (CAD 2399) and lowest for Manitoba (CAD 1126). Travel costs were highest for Alberta (CAD 294) and lowest for British Columbia (CAD 67). Parking costs were highest for Ontario (CAD 103) and lowest for Manitoba (CAD 53). A total of 41% of patients reported reducing spending, but this increased to 52% for families earning

CONCLUSIONS

Levels of financial burden for patients with cancer in Canada vary provincially, including for OOPC, travel and parking costs, and lost income. Decisions to forego cancer care are highest in relation to vitamins/supplements, CAM, and drugs. Provincial differences suggest that regional health policies and demographics may impact patients' overall financial burden.

Financial toxicity in early-onset colorectal cancer: A National Health Interview Survey study

BACKGROUND

Financial toxicity is increasingly recognized as a devastating outcome of cancer treatment but is poorly characterized in patients with early-onset colorectal cancer. Young patients are particularly vulnerable to financial toxicity as they are frequently underinsured and may suffer significant disruptions to professional and financial growth. We hypothesized that financial toxicity associated with colorectal cancer treatment confers long-lasting effects on patients' well-being and disproportionately impacts patients diagnosed at <50 years of age.

METHODS

A retrospective cross-sectional analysis of the National Health Interview Survey from years 2019 to 2021 was performed. Patients with a history of colorectal cancer were included and stratified by age at diagnosis. Randomly selected age-matched controls with no cancer history were used for comparison. The primary endpoint was financial toxicity, as assessed by a composite score formulated from 12 National Health Interview Survey items. The secondary endpoint was food security assessed by the United States Department of Agriculture's food security scale, embedded in the National Health Interview Survey.

RESULTS

When compared to age-matched controls, patients with colorectal cancer experienced significant financial toxicity, as reflected by a composite financial toxicity score (P = .027). Within patients with colorectal cancer, female sex (adjusted odds ratio = 1.46, P = .046) and early-onset disease (adjusted odds ratio = 2.11, P = .002) were found to significantly increase the risk of financial toxicity. Patients with early-onset colorectal cancer more frequently experienced food insecurity (P = .011), delayed necessary medical care (P = .053), mental health counseling (P = .043), and filling prescriptions (P = .007) due to cost when compared to patients with average-onset colorectal cancer.

CONCLUSION

Colorectal cancer is associated with significant long-term financial toxicity, which disproportionately impacts patients diagnosed at <50 years of age. Targeted interventions are warranted to reduce financial toxicity for patients with high-risk colorectal cancer.

The socioeconomic impact of cancer on patients and their relatives: Organisation of European Cancer Institutes task force consensus recommendations on conceptual framework, taxonomy, and research directions

Loss of income and out-of-pocket expenditures are important causes of financial hardship in many patients with cancer, even in high-income countries. The far-reaching consequences extend beyond the patients themselves to their relatives, including caregivers and dependents. European research to date has been limited and is hampered by the absence of a coherent theoretical framework and by heterogeneous methods and terminology. To address these shortages, a task force initiated by the Organisation of European Cancer Institutes (OECI) produced 25 recommendations, including a comprehensive definition of socioeconomic impact from the perspective of patients and their relatives, a conceptual framework, and a consistent taxonomy linked to the framework. The OECI task force consensus statement highlights directions for future research with a view towards policy relevance. Beyond descriptive studies into the dimension of the problem, individual severity and predictors of vulnerability should be explored. It is anticipated that the consensus recommendations will facilitate and enhance future research efforts into the socioeconomic impact of cancer and cancer care, providing a crucial reference point for the development and validation of patient-reported outcome instruments aimed at measuring its broader effects.

Cost and value of cancer medicines in a single-payer public health system in Ontario, Canada: a cross-sectional study

BACKGROUND

The financial impact of cancer medicines on health systems is not well known. We describe temporal trends in expenditure on cancer medicines within the single-payer health system of Ontario, Canada, and the extent of clinical benefit these treatments offer.

METHODS

In this cross-sectional study, we identified cancer medicines and expenditures from formularies and costing databases (the New Drug Funding Program, Ontario Drug Benefit Program, and The High-Cost Therapy Funding Program) during 10 consecutive years (April 1, 2012, to March 31, 2022) in Ontario, Canada. For intravenous medicines, we applied the European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) to identify expenditures associated with substantial clinical benefit. We also identified treatments associated with improved overall survival or quality of life.

FINDINGS

69 intravenous and 98 oral or injectable medicines were funded during 2012-22. Annual expenditure on cancer medicines increased by approximately 15% per year during 2012-22; the increase was more rapid in the most recent 4 years. Total expenditure on cancer medicines in the 2021-22 financial year was CA$1·7 billion. Immune checkpoint inhibitors were the single biggest expense by class ($284 million), representing 17% of the entire cancer medicine annual budget. Drugs with the highest individual costs were lenalidomide ($178 million) and pembrolizumab ($163 million), each accounting for around 10% of the entire budget. 29 (76%) of 38 indications eligible for ESMO-MCBS scoring met the threshold for substantial clinical benefit. Eight (21%) indications had no randomised trial evidence of improved overall survival, and only four (11%) were associated with improved QOL. $346 million (67% of the expenditure on intravenous cancer medicines) was spent on drugs that improved median overall survival by more than 6 months, $82 million (16%) was spent on medicines with overall survival gains of 3-6 months, and $32 million (6%) was spent on medicines with overall survival gains of less than 3 months. $53 million (10%) was spent on medicines with no established improvement in overall survival.

INTERPRETATION

Costs of cancer medicines to the Canadian health system are increasing rapidly. Most funded indications met thresholds for substantial clinical benefit and two-thirds of the expenditure were for medicines that improve survival by more than 6 months. Whether this cost trajectory can be maintained in a sustainable, equitable, high-quality health system is unclear. Efforts are needed to ensure the price of medicines with substantial benefit is affordable and funding of treatments with very modest benefit might need to be re-assessed, particularly when alternative supportive and palliative therapies are available.

FUNDING

Experiences of financial toxicity among caregivers of cancer patients: a meta-synthesis of qualitative studies

OBJECTIVES

The purpose of this study was to explore the experience of financial toxicity among caregivers of cancer patients and to provide recommendations for subsequent intervention strategies.

METHODS

Computer searches of PubMed, EmBase, The Cochrane Library, Web of Science, CINAHL (EBSCO), CNKI, Wanfang database, and SinoMed for qualitative studies experience of financial toxicity among caregivers cancer patients. The search time frame was from the establishment of the database to May 2023. The quality of included studies was assessed using the Qualitative Research Checklist from the Joanna Briggs Institute (JBI) Reviewer's Manual. The meta-synthesis was integrated following the meta-aggregation method proposed by the Joanna Briggs Institute (JBI) and reported following the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines.

RESULTS

A total of nine studies were included, distilling 25 qualitative findings into nine new categories and synthesizing three synthesized findings: caregivers have strong negative experiences that affect their family relationships, daily work and life; caregivers use different strategies to cope with financial toxicity; needs and expectations of caregivers coping with financial toxicity.

CONCLUSIONS

Financial toxicity among caregivers of cancer patients affects their daily lives. Receiving timely recognition of this financial burden and providing assistance to enhance their coping skills are crucial in mitigating its impact. Healthcare professionals should focus on the financial toxicity experienced by caregivers of people with cancer, address their supportive needs, and develop a comprehensive support system to improve caregivers' coping abilities and quality of life.

Exploring the Future of Cancer Impact in Alberta: Projections and Trends 2020-2040

The impact of cancer in Alberta is expected to grow considerably, largely driven by population growth and aging. The Future of Cancer Impact (FOCI) initiative offers an overview of the present state of cancer care in Alberta and highlights potential opportunities for research and innovation across the continuum. In this paper, we present a series of detailed projections and analyses regarding cancer epidemiological estimates in Alberta, Canada. Data on cancer incidence and mortality in Alberta (1998-2018) and limited-duration cancer prevalence in Alberta (2000-2019) were collected from the Alberta Cancer Registry. We used the Canproj package in the R software to project these epidemiological estimates up to the year 2040. To estimate the direct management costs, we ran a series of microsimulations using the OncoSim All Cancers Model. Our findings indicate that from 2020, the total number of annual new cancer cases and cancer-related deaths are projected to increase by 56% and 49% by 2040, respectively. From 2019, the five-year prevalence of all cancers in Alberta is projected to increase by 86% by 2040. In line with these trends, the overall direct cost of cancer management is estimated to increase by 53% in 2040. These estimates and projections are integral to future strategic planning and investment.

Integrative Oncology Care of Symptoms of Anxiety and Depression in Adults With Cancer: Society for Integrative Oncology-ASCO Guideline

PURPOSE

To provide evidence-based recommendations to health care providers on integrative approaches to managing anxiety and depression symptoms in adults living with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, methodology, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2023. Outcomes of interest included anxiety or depression symptoms as measured by validated psychometric tools, and adverse events. Expert panel members used this evidence and informal consensus with the Guidelines into Decision Support methodology to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 110 relevant studies (30 systematic reviews and 80 randomized controlled trials) to inform the evidence base for this guideline.

RECOMMENDATIONS

Recommendations were made for mindfulness-based interventions (MBIs), yoga, relaxation, music therapy, reflexology, and aromatherapy (using inhalation) for treating symptoms of anxiety during active treatment; and MBIs, yoga, acupuncture, tai chi and/or qigong, and reflexology for treating anxiety symptoms after cancer treatment. For depression symptoms, MBIs, yoga, music therapy, relaxation, and reflexology were recommended during treatment, and MBIs, yoga, and tai chi and/or qigong were recommended post-treatment.

DISCUSSION

Issues of patient-health care provider communication, health disparities, comorbid medical conditions, cost implications, guideline implementation, provider training and credentialing, and quality assurance of natural health products are discussed. While several approaches such as MBIs and yoga appear effective, limitations of the evidence base including assessment of risk of bias, nonstandardization of therapies, lack of diversity in study samples, and lack of active control conditions as well as future research directions are discussed.Additional information is available at www.asco.org/survivorship-guidelines.

Perspectives of Cancer Survivors with Low Income: A Content Analysis Exploring Concerns, Positive Experiences, and Suggestions for Improvement in Survivorship Care

The number of cancer survivors in Canada has reached 1.5 million and is expected to grow. It is important to understand cancer survivors' perspectives about the challenges they face after treatment is completed. Many factors create barriers to accessing assistance, and limited income may be a significant one. This study is a secondary analysis of data from a publicly available databank (Cancer Survivor Transitions Study) regarding the experiences of Canadian cancer survivors. The goal was to explore major challenges, positive experiences, and suggestions for improvement in survivorship care for low-income Canadian cancer survivors one to three years following treatment. A total of 1708 survey respondents indicated a low annual household income (<$25,000 CD). A content analysis was performed utilizing written comments to open-ended questions. The major challenges respondents described focused on physical capacity limits and treatment side effects; positive experiences emphasized support and attentive care; and suggestions for improvements highlighted the need for better support, information about self-care and side effect management, and timely follow-up care. The relationships between household income and the management of survivors' physical, emotional, and practical concerns require consideration. The design of follow-up care plans, programs, services, and financial assessments of patients may prepare survivors for predictable issues and costs in their transition to survivorship.

A prospective evaluation of patient perspectives and financial considerations during prostate cancer treatment decision-making

INTRODUCTION

In universal healthcare systems, patients may still encounter financial obstacles from cancer treatments, potentially influencing treatment decision-making. We investigated the relationship between socioeconomic status and treatment decision-making as it pertains to patient values, preferences, and perceived barriers to care for localized prostate cancer.

METHODS

We conducted a prospective study of patients undergoing a prostate biopsy for the initial detection of prostate cancer. Sociodemographic variables were collected, with validated instruments used to determine health literacy levels. Patients were divided into two groups using self-reported income; those with a positive identification of prostate cancer underwent additional surveys to ascertain their knowledge of their diagnosis, treatment-related preferences, and socioeconomic barriers to care. Descriptive statistics were used.

RESULTS

Of 160 patients, approximately one-third were classified as having low health literacy. Within the low-income group, education levels were lower (34.6% had less than high school education vs. 10.2% in the high-income group) and unemployment rates higher (75.0% unemployed vs. 38.9% in the high-income group). Low-income patients with prostate cancer placed greater importance on indirect out-of-pocket expenses related to treatment (78.3% vs. 33.3%, p=0.001), higher emphasis on treatment-related travel time (50% vs. 15.1%, p=0.004), and more often had difficulty paying for healthcare services in the past (30.9% vs. 9.1%, p=0.02).

CONCLUSIONS

Patients with lower household incomes have unique treatment values and decision-making preferences. They may experience additional challenges and barriers to obtaining cancer care, at least partly related to indirect costs. These findings should be considered when framing prostate cancer treatment discussions and designing patient-facing health information.

Understanding the economic burden of cancer care and the utility of health insurance: An exploratory cross-sectional study in a tertiary care hospital in Karnataka, India

Background

Families and caregivers of cancer patients experience significant financial challenges associated with out-of-pocket (OOP) expenditures.

Objectives

This study aims to assess the OOP expenditure and its impact on the livelihood of patients and families, associated with receiving cancer care from a teaching hospital in Karnataka.

Materials and Methods

It focuses on understanding health insurance use and its effects on OOP expenses for cancer care based on data obtained from 271 patients receiving treatment for more than 6 months. A structured questionnaire was developed and used for data collection and focused on obtaining direct costs such as consultation fees, surgery costs, and radiotherapy costs and indirect costs such as travel expenses, food costs, and patient income loss, as well as questions that measure the impact of the financial burden on patients and their associated livelihood.

Results

In the present study, the median cost of OOP expense incurred for cancer treatment is estimated to be 3.10 lakh Indian rupees. It was also found that patients enrolled in public health insurance schemes, especially Ayushman Bharath-Arogya Karnataka have lesser OOP expenditure than those with either private health insurance or no health insurance.

Conclusions

This indicates the need for effective implementation of various public health insurance schemes and their ability to protect patients from huge OOP expenses and related financial risks.

A burden shared: the financial, psychological, and health-related consequences borne by family members and caregivers of people with cancer in India

In India, approximately 1.4 million new cases of cancer are recorded annually, with 26.7 million people living with cancer in 2021. Providing care for family members with cancer impacts caregivers' health and financial resources. Effects on caregivers' health and financial resources, understood as family and caregiver "financial toxicity" of cancer, are important to explore in the Indian context, where family members often serve as caregivers, in light of cultural attitudes towards family. This is reinforced by other structural issues such as grave disparities in socioeconomic status, barriers in access to care, and limited access to supportive care services for many patients. Effects on family caregivers' financial resources are particularly prevalent in India given the increased dependency on out-of-pocket financing for healthcare, disparate access to insurance coverage, and limitations in public expenditure on healthcare. In this paper, we explore family and caregiver financial toxicity of cancer in the Indian context, highlighting the multiple psychosocial aspects through which these factors may play out. We suggest steps forward, including future directions in (1) health services research, (2) community-level interventions, and (3) policy changes. We underscore that multidisciplinary and multi-sectoral efforts are needed to study and address family and caregiver financial toxicity in India.

Financial Toxicity in Cancer Care: Implications for Clinical Care and Potential Practice Solutions

Patients with cancer face an array of financial consequences as a result of their diagnosis and treatment, collectively referred to as financial toxicity (FT). In the past 10 years, the body of literature on this subject has grown tremendously, with a recent focus on interventions and mitigation strategies. In this review, we will briefly summarize the FT literature, focusing on the contributing factors and downstream consequences on patient outcomes. In addition, we will put FT into context with our emerging understanding of the role of social determinants of health and provide a framework for understanding FT across the cancer care continuum. We will then discuss the role of the oncology community in addressing FT and outline potential strategies that oncologists and health systems can implement to reduce this undue burden on patients with cancer and their families.

Mothers with Cancer: An Intersectional Mixed-Methods Study Investigating Role Demands and Perceived Coping Abilities

Mothers with cancer report guilt associated with failing to successfully balance their parental roles and cancer. This study utilized a cross-sectional mixed-methods design and intersectional framework to investigate the multiple roles that mothers with cancer assume and their perceived coping ability. Participants included mothers diagnosed with any type or stage of cancer, in treatment or ≤3 years post-treatment, and experiencing cancer-related disability with a dependent child (<18 years, living at home). Participants completed a questionnaire battery, semi-structured interview, and optional focus group. Descriptive statistics, correlations, and thematic inductive analyses are reported. The participants' (N = 18) mean age was 45 years (SD = 5.50), and 67% were in active treatment. Their role participation (M = 42.74, ±6.21), role satisfaction (M = 43.32, ±5.61), and self-efficacy (M = 43.34, ±5.62) were lower than the general population score of 50. Greater role participation and higher role satisfaction were positively correlated (r = 0.74, p ≤ 0.001). A qualitative analysis revealed that the mothers retained most roles, and that their quality of life depended on their capacity to balance those roles through emotion-focused and problem-focused coping. We developed the intersectional Role Coping as a Mother with Cancer (RCMC) model, which has potential research and clinical utility.

Evaluation of parking-related financial toxicity associated with cancer treatments in Western Canada

INTRODUCTION/BACKGROUND

Patients and their caregivers incur numerous out-of-pocket costs while receiving oncologic treatments. These expenses are often overlooked by clinicians, even in countries with publicly funded healthcare systems. Parking fees are one such category of expenses that contribute to financial toxicity in cancer care. Patients with cancer often have protracted treatment courses, especially if they are receiving external beam radiation therapy. It is not clear if cancer center parking fees influence city-specific indices such as city-specific cost of living. The aim of this study was to evaluate cancer center parking fees in Western Canada and to elucidate any correlation between daily cost of parking and the city-specific indices.

METHODS

This was a cross sectional study conducted from February 1st, 2022, to March 1st, 2022. An online search was undertaken to obtain the publicly available parking information for the regional and community cancer centers in the provinces of British Columbia, Alberta, Manitoba, and Saskatchewan. Telephone calls were made with parking offices or switchboards to obtain this information for the cancer centers that did not have online information on parking. Cancer center address transit scores, median city household income, and city-specific cost of living scores were obtained online for the cities where the cancer centers were located. Pearson correlation and a zero-inflated negative binomial model were used for statistical analysis.

RESULTS

Data was collected from 115 community and regional cancer centers distributed across the 4 provinces. The median hourly parking fee across all provinces was 2.00 Canadian Dollars (CAD) (Interquartile range (IQR), 0-4.25), whereas the median daily cost of parking was 9.50 CAD (IQR, 0-13.13). The median cancer center address transit score was 41.00 (IQR, 12.00-50.50). There was a statistically significant (p=0.029) positive correlation between the daily cost of parking and city cost of living. The correlation coefficient between the two variables was 0.412. Furthermore, there was a statistically significant (p<0.001) positive correlation between daily cost of parking and cancer center address transit score. The correlation coefficient between the two variables was 0.676. In addition, there was a strong negative correlation between the cancer center address transit score and the presence of free parking with a correlation coefficient of -0.613 (p<0.001). There was a nonsignificant (p=0.88) negative correlation between cost of living and the presence of free parking with a correlation coefficient of -0.028.

DISCUSSION

The results of this study demonstrate that daily cost of parking for community and regional cancer centers in Western Canada significantly influences city-specific cost of living and cancer center address transit scores to a varying degree. This demonstrates that the influence of parking fees on patients with cancer is multilayered with significant direct and indirect effects. This can contribute to loss of wage and added financial burden on patients and their caregivers in higher-cost provinces. The presence of free parking at community and regional cancer centers had a statistically significant negative correlation with the cancer center address transit score. This suggests that cities with more free parking also have less robust public transit systems. Conversely, the presence of an extensive public transit system leads to a lower likelihood of free parking being available at cancer centers.

CONCLUSION

The presence of a strong public healthcare system does not necessarily address all aspects of cancer-related financial toxicity. There is strong evidence of both positive and negative correlations between city specific indices and cancer center parking fees in Western Canada. Policy makers and stakeholders should be cognizant of this interplay between the various city specific indices and parking fees for patients with cancer. Policies on provincial and federal levels should be implemented to address this increasingly problematic burden on oncologic patients.

Predictors of prostate cancer survivors' engagement in self-management behaviors

INTRODUCTION

Prostate cancer survivors experience a multitude of late treatment effects, resulting in greater unmet needs, elevated symptom burden, and reduced quality of life. Survivors can engage in appropriate self-management strategies post-treatment to help reduce the symptom burden. The objectives of this study were to: 1) survey the unmet needs of prostate cancer survivors using the validated Cancer Survivor Unmet Needs instrument; 2) explore predictors of high unmet needs; and 3) investigate prostate cancer survivors' willingness to engage in self-management behaviors.

METHODS

Survivors were recruited from a prostate clinic and a cross-sectional survey design was employed. Inclusion criteria was having completed treatment two years prior. Descriptive statistics were used to summarize participant characteristics. Univariate and multivariate analyses were done to determine predictors of unmet needs and readiness to engage.

RESULTS

A total of 206 survivors participated in the study, with a mean age of 71 years. Most participants were university/college-educated (n=123, 61%) and had an annual household income of ≥$99 999 (n=74, 38%). Participants reported erectile dysfunction (81%) and nocturia (81%) as the most frequently experienced symptoms with the greatest symptom severity χ̄=5.8 and χ̄=4.5, respectively). More accessible parking was the greatest unmet need in the quality-of-life domain (n=34/57, 60%). Overall, supportive care unmet needs were predicted by symptom severity on both univariate (p<0.001) and multivariate analyses (odds ratio [OR ] 1.81, 95% confidence interval [CI] 0.92-1.00, p<0.001). Readiness to engage in self-management was predicted by an income of <$49 000 (OR 3.99, 95% CI 1.71-9.35, p=0.0014).

CONCLUSIONS

Income was the most significant predictor of readiness to engage in self-management. Consideration should be made to establishing no-cost and no-barrier education programs to educate survivors about how to engage in symptom self-management.

The Financial Impact of Palliative Care and Aggressive Cancer Care on End-of-Life Health Care Costs

BACKGROUND

Medicare cancer expenditures in the last month of life have increased. Aggressive cancer care at the end-of-life (ACEOL) is considered poor quality care. We used Geisinger Health Plan (GHP) last month's costs for cancer patients who died in 2018 and 2019 to determine the costs of and influence of Palliative Care (PC) on ACEOL.

METHOD

Patients with GHP ages 18-99 who died in 2018 and 2019 were included. Demographic, clinical characteristics, and Charlson Comorbid Index were compared across care groups defined as no ACEOL indicator, 1 or more than 1 indicator. Differences between groups were compared with Kruskal-Wallis tests and one-way ANOVA for 3 groups. Median two-sample tests and independent t-tests compared groups of 2. A P-value </= .05 indicated statistical significance.

RESULTS

Of 608 eligible patients; 261 had no indicator, 133 had 1 and 214 > 1. There were incremental cost increases with each additional ACEOL indicator (p = < .0001). Palliative Care <90 days before death was associated with increased costs while consultations >90 days before death lowered cost (P < .0001) due to reduced chemotherapy in the last month. Completed ADs reduced cost by $4000.

DISCUSSION

ACEOL indicators multiply costs during the last month of life. Palliative care instituted >90 days before death reduces chemotherapy in the last month of life and AD reduces health care costs.

CONCLUSION

Cancer health care costs increase with indicators of ACEOL. Palliative care consultations >90 days before death; ADs reduce cancer health care costs.

The Role of Standardized Phase Angle in the Assessment of Nutritional Status and Clinical Outcomes in Cancer Patients: A Systematic Review of the Literature

Compared with the phase angle (PA), the predictive ability of the standardized phase angle (SPA) in assessing nutritional status and clinical outcomes in cancer patients remains uncertain. This review aimed to assess (1) the relationship between SPA and nutritional status and clinical outcomes (including complications and survival) in cancer patients; (2) the predictive ability of SPA alone and in comparison with the predictive ability of PA; and (3) the cut-off value of SPA in cancer patients. Studies that addressed the relationship of SPA use to nutritional status, complications, and survival in cancer patients were searched and identified from six electronic databases (PubMed, Medline, CINAHL, Embase, Web of Science, and the Cochrane Library). The included studies were considered to meet the following criteria: English studies with original data that reflected the effects of SPA on nutritional status and clinical outcomes (including complications and survival) and reported a cut-off value of SPA in cancer patients aged ≥18. Thirteen studies that included a total of 2787 participants were evaluated. Five studies assessed the relationship between SPA and nutritional status, and four of them reported a positive relationship between SPA and nutritional status in cancer patients, even considering SPA as a predictor. Twelve studies assessed the relationship between SPA and clinical outcomes in cancer patients. Two-thirds of the studies that evaluated complications reported the predictive ability of SPA; 30% of survival studies reported a positive relationship, 40% reported SPA as a predictor, and 30% reported no relationship. The standard cut-off value for SPA has not yet been determined. Data from the selected studies suggest that SPA might be a predictor of nutritional status. Further studies are needed to determine the value of SPA in predicting nutritional status and clinical outcomes in cancer patients.

Occupational and Financial Setbacks in Caregivers of People with Colorectal Cancer: Considerations for Caregiver-Reported Outcomes

Family caregivers of patients with cancer provide substantial physical, emotional, and functional care throughout the cancer trajectory. While caregiving can create employment and financial challenges, there is insufficient evidence to inform the development of caregiver-reported outcomes (CROs) that assess these experiences. The study purpose was to describe the occupational and financial consequences that were important to family caregivers of a patient with colorectal cancer (CRC) in the context of public health care, which represent potential considerations for CROs. In this qualitative Interpretive Description study, we analyzed interview data from 78 participants (25 caregivers, 37 patients, and 16 healthcare providers). Our findings point to temporary and long-term occupational and financial setbacks in the context of CRC. Caregiving for a person with CRC involved managing occupational implications, including (1) revamping employment arrangements, and (2) juggling work, family, and household demands. Caregiver financial struggles included (1) responding to financial demands at various stages of life, and (2) facing the spectre of lifelong expenses. Study findings offer novel insight into the cancer-related occupational and financial challenges facing caregivers, despite government-funded universal health care. Further research is warranted to develop CRO measures that assess the multifaceted nature of these challenges.

Measuring the indirect cost associated with advanced non-small cell lung cancer: a nationwide cross-sectional study in China

PURPOSE

This study was conducted to estimate the indirect cost of locally advanced and metastatic non-small cell lung cancer (NSCLC) without sensitizing EGFR and ALK alterations in China and explore the predictors from both patient and caregiver perspectives.

METHODS

Data were obtained from a nationwide cross-sectional study for the patients with advanced NSCLC (stage IIIB-IV) and their caregivers. Indirect medical cost was estimated as health productivity loss based on self-reported income and loss of work time. The generalized linear model was used to assess the independent associations between statistically significant variables and indirect economic burden.

RESULTS

611 pairs of patients and patient caregivers from 13 medical centers in five provinces in China participated in this investigation. The indirect medical cost associated with advanced NSCLC since the patient diagnosed was $1413 per capita in China. General linear regression results showed that the indirect medical cost was significantly influenced by duration of disease since diagnosis, treatment options, caregivers' occupation and age (P < 0.05).

CONCLUSION

The indirect economic burden linked to advanced NSCLC in China is considerable on patients, and their caregivers. To minimize the severe challenges of indirect economic burden related to advanced NSCLC, expanding the coverage of the medical insurance and assistance system to reimburse part of the indirect costs related to cancer, as well as strengthening the accessibility for more effective therapies to improve the prognosis of advanced NSCLC, and further promote the patients and their caregivers to return to work or normal life may be the potentially feasible approaches.

Balancing Work and Cancer Care: Challenges Faced by Employed Informal Caregivers

Simple Summary

Caregiving for a family member or close friend with cancer can be particularly demanding for employed individuals who are juggling work responsibilities while providing care. With an eye toward stimulating research to develop programs and resources to support this vulnerable subgroup of caregivers, this narrative review first describes the financial, work, and mental health impacts of cancer on employed caregivers. Next, critical knowledge gaps are identified and directions for future research are described. The article concludes by formulating an agenda for practice that includes a multipronged effort on behalf of employers, healthcare, and community-based organizations to support and empower employed cancer caregivers.

Abstract

Individuals with cancer commonly rely on their informal caregivers (e.g., spouse/partner, family member, close friend) to help them manage the demands of the disease and its treatment. Caregiving, including helping with patient care, performing household chores, and providing emotional and practical support, can be particularly demanding for employed caregivers, who must juggle their work responsibilities while providing care. Although a burgeoning literature describes the toll that balancing these oft-competing demands can exact, few resources exist to support employed cancer caregivers. To address this gap, we conducted a narrative review of the impacts of cancer on employed caregivers. We found that employed caregivers experience significant financial impacts in terms of lost time and income. They also experience a variety of work-related (e.g., reduced productivity, absenteeism) and mental health (e.g., stress, burden) impacts. Going forward, prospective studies are needed to characterize changes in caregiver support needs and preferences at different time points along the cancer care continuum (e.g., at diagnosis, during treatment, end-of-life) so that appropriate workplace accommodations can be provided. More population-based studies are also needed to develop models for identifying caregivers who are at increased risk for poor employment or mental health outcomes so that more targeted support programs can be developed. Ultimately, a multipronged effort on behalf of employers, healthcare, and community-based organizations may be needed to support and empower this vulnerable subgroup.

The Burden of Health-Related Out-of-Pocket Cancer Costs in Canada: A Case-Control Study Using Linked Data

Background: The burden of out-of-pocket costs among cancer patients/survivors in Canada is not well understood. The objective of this study was to examine the health-related out-of-pocket cost burden experienced by households with a cancer patient/survivor compared to those without, examine the components of health-related costs and determine who experiences a greater burden. Data and methods: This study used a data linkage between the Survey of Household Spending and the Canadian Cancer Registry to identify households with a cancer patient/survivor (cases) and those without (controls). The out-of-pocket burden (out-of-pocket costs measured relative to household income) and mean costs were described and regression analyses examined the characteristics associated with the household out-of-pocket burden and annual out-of-pocket costs. Results: The health-related out-of-pocket cost burden and annual costs measured in households with a cancer patient/survivor were 3.08% (95% CI: 2.55–3.62%) and CAD 1600 (95% CI: 1456–1759), respectively, compared to a burden of 2.84% (95% CI: 2.31–3.38) and annual costs of CAD 1511 (95% CI: 1377–1659) measured in control households, respectively. Households with a colorectal cancer patient/survivor had a significantly higher out-of-pocket burden compared to controls (mean difference: 1.0%, 95% CI: 0.18, 0.46). Among both cases and controls, the lowest income quintile households experienced the highest health-related out-of-pocket cost burden. Interpretation: Within a universal health care system, it is still relevant to monitor health-related out-of-pocket spending that is not covered by existing insurance mechanisms; however, this is not routinely assessed in Canada. We demonstrate the feasibility of measuring such costs in households with a cancer patient/survivor using routinely collected data. While the burden and annual health-related out-of-pocket costs of households with a cancer patient/survivor were not significantly higher than control households in this study, the routine measurement of out-of-pocket costs in Canada could be systemized, providing a novel, system-level, equity-informed performance indicator, which is relevant for monitoring inequities in the burden of out-of-pocket costs.

Unmet supportive care needs of people with advanced cancer and their caregivers: a systematic scoping review

Examining and addressing unmet care needs is integral to improving the provision and quality of cancer services. This review explored the prevalence of unmet supportive care needs, and factors associated with unmet need, in adults with advanced cancers (solid and hematological malignancies) and their caregivers. Electronic databases (PubMed, CINAHL, EMBASE) were searched, producing 85 papers representing 81 included studies. People with advanced cancer reported the highest unmet needs in financial, health system and information, psychological, and physical and daily living domains, whereas caregivers reported the highest unmet needs in psychological, and patient care and support domains. Distress, depression, and anxiety were associated with higher unmet needs across all unmet need domains for people with advanced cancer and their caregivers. Substantial heterogeneity in study populations and methods was observed. Findings from this review can inform targeted strategies and interventions to address these unmet needs in people with advanced cancer.

The Economic Burden of Cancer in Canada from a Societal Perspective

Cancer patients and their families experience considerable financial hardship; however, the current published literature on the economic burden of cancer at the population level has typically focused on the costs from the health system’s perspective. This study aims to estimate the economic burden of cancer in Canada from a societal perspective. The analysis was conducted using the OncoSim-All Cancers model, a Canadian cancer microsimulation model. OncoSim simulates cancer incidence and deaths using incidence and mortality data from the Canadian Cancer Registry and demography projections from Statistics Canada. Using a phase-based costing framework, we estimated the economic burden of cancer in Canada in 2021 by incorporating published direct health system costs and patients’ and families’ costs (out-of-pocket costs, time costs, indirect costs). From a societal perspective, cancer-related costs were CAD 26.2 billion in Canada in 2021; 30% of costs were borne by patients and their families. The economic burden was the highest in the first year after cancer was diagnosed (i.e., initial care). During this time, patients and families’ costs amounted to almost CAD 4.8 billion in 2021. This study provides a comprehensive estimate of the economic burden of cancer, which could inform cost–benefit analyses of proposed cancer prevention interventions.

Linking Intermediate to Final “Real-World” Outcomes: Is Financial Toxicity a Reliable Predictor of Poorer Outcomes in Cancer?

Traditionally, economic evaluations are based on clinical trials with well-defined patient populations that exclude many patient types. By contrast, studies that incorporate general patient populations end up including those in lower income categories, some of whom have significant financial burdens (often described as financial toxicity) related to their care. Consideration of these patient burdens when examining the incremental cost-effectiveness of newer treatments from a clinical trial perspective can result in differing conclusions regarding cost-effectiveness. The challenge is to reliably assess the link between financial toxicity, quality of life and potential decisions to forego or delay care. It is also well-documented that these financial effects are not evenly distributed across populations, with those with low income and of black or Latino decent being most affected. There is a paucity of literature in this space, but some of the early work has suggested that for lung, breast, colorectal and ovarian cancers there are poorer quality-of-life scores and/or shorter overall survival for those experiencing financial toxicity. Hence, we may see both a lower quality of life and a shorter duration of life for these populations. If this is the case, additional considerations include: are the benefits of newer, more-expensive treatment strategies muted by the lack of adherence to these newer treatments due to financial concerns, and, if true, can these effects be effectively quantified as “real-world” outcomes? This rapid review examines these possibilities and the steps that may be required to examine this reliably.

Not All Canadian Cancer Patients Are Equal—Disparities in Public Cancer Drug Funding across Canada

Canada lacks a national drug insurance plan. The home province or territory of a patient determines which cancer drugs are available on the public formulary, who is eligible for public coverage and what portion of the financial burden of cancer care falls to the individual. This narrative review describes the current interprovincial disparities in access to cancer drugs across Canada. Health technology assessment (HTA) of drugs at a provincial and territory level is a closed process, does not necessarily follow the recommendations of national HTA and leads to further delays in drug access. The public coverage of take-home cancer drugs (THCDs) in Ontario and the Atlantic provinces is often fragmented, unnecessarily complex and a barrier to cancer drug access. Policy solutions to address inter-provincial formulary variation and poor access to THCDs are discussed.

Co-design of a return-to-work intervention after breast cancer treatments: feasibility study protocol (Preprint)

Background

The mortality rate from breast cancer has been declining for many years, and the population size of working-age survivors is steadily increasing. However, the recurrent side effects of cancer and its treatment can result in multiple disabilities and disruptions to day-to-day life, including work disruptions. Despite the existing knowledge of best practices regarding return to work (RTW) for breast cancer survivors, only a few interdisciplinary interventions have been developed to address the individualized needs and multiple challenges of breast cancer survivors, health care professionals, and employer and insurer representatives. Thus, it seems appropriate to develop RTW interventions collaboratively by using a co-design approach with these specific stakeholders.

Objective

This paper presents a protocol for developing and testing an innovative, interdisciplinary pilot intervention based on a co-design approach to better support RTW and job retention after breast cancer treatment.

Methods

First, a participatory research approach will be used to develop the intervention in a co-design workshop with 12 to 20 participants, including people affected by cancer, employer and insurer representatives, and health care professionals. Next, a pilot intervention will be tested in a primary care setting with 6 to 8 women affected by breast cancer. The acceptability and feasibility of the pilot intervention will be pretested through semistructured interviews with participants, health care professionals, and involved patient partners. The transcribed data will undergo an iterative content analysis.

Results

The first phase of the project—the co-design workshop—was completed in June 2021. The pilot test of the intervention will begin in spring 2022. The results from the test will be available in late 2022.

Conclusions

The project will offer novel data regarding the use of the co-design approach for the development of innovative, co-designed interventions. In addition, it will be possible to document the acceptability and feasibility of the pilot intervention with a primary care team. Depending on the results obtained, the intervention could be implemented on a larger scale.

Self-Management About Adjuvant Therapy in Breast Cancer Survivors: A Qualitative Study

OBJECTIVE

This study aims to describe the experience and connotations of self-management about adjuvant therapy (AT) in Chinese breast cancer survivors (BCS) and explore possible factors that affect their self-management level.

METHODS

Semi-structured interviews were conducted in postoperative BCS undergoing AT using a qualitative description method. The conceptual structure and connotations were extracted after researchers collected and coded interview transcripts.

RESULTS

After interviewing 29 patients, the conceptual framework of self-management in BCS during AT was optimized with three major themes: medical-related, emotion, and role management. Medical-related management includes AT-related adverse reactions; medical cooperation and knowledge acquisition; recovery and protection of affected limb; medical compliance; body image; sexual function and fertility; healthy lifestyle; catheter daily protection; and AT-related financial burdens. Emotion management includes recognition, prevention, and regulation of negative emotions. Role management consists of three aspects: family role, social role, and work role.

CONCLUSION

The conceptual structure and connotations formed in this study can help researchers to evaluate and intervene in the self-management ability of BCS during AT, so as to formulate the best model of care to improve their quality of life and clinical outcomes.

Exploring the relationships between income and emotional/practical concerns and help-seeking by older adult cancer survivors: A secondary analysis

PURPOSE

The number of older cancer survivors is growing rapidly and expected to double through the next decade. Survivors can face challenges from treatment as well as other co-morbid conditions which may influence quality of living and generate distress. Understanding more about factors influencing whether older cancer survivors receive the help they desire is important for cancer program planning. The purpose of this analysis was to understand relationships between income and emotional/practical concerns, help-seeking experiences and unmet needs of adults 65+ years one to three years following cancer treatment.

MATERIALS AND METHODS

A survey was conducted with randomly selected Canadian cancer survivors about their survivorship care. Drawing from these publicly available data, this secondary analysis examines prevalence of concerns, help-seeking, receipt of help, reasons for not seeking help, responses to information questions, and overall unmet needs for trends across income groups.

RESULTS

7975 respondents 65+ years responded, of which the 5891 (73.9%) indicating annual household income were analyzed. Over 80% responded to questions regarding emotional/practical concerns following treatment with the largest proportions reporting emotional concerns for anxiety/fear of cancer returning (63%) and depression (49%), and practical concerns regarding transportation for appointments (33%) and paying healthcare bills (31%). Individuals with household incomes <$25,000 reported higher levels of concern than other income groups and higher proportions sought assistance for their concerns. Across income levels, 20% reported difficulty finding assistance to address their concerns.

DISCUSSION

Older cancer survivors across all income categories reported emotional/practical concerns, lack of information about these issues, and unmet needs regarding both emotional and practical concerns. Many encountered challenges obtaining help with those in lower income categories more severely affected despite Canada's universal health care system. Financial burden ought to be assessed with older survivors on an on-going basis to ensure relevant intervention.

Unequal distribution of financial toxicity among people with cancer and its impact on access to care: a rapid review

PURPOSE OF REVIEW

Research demonstrates that patients and their families often carry a good portion of the economic burden during and following cancer treatment, frequently resulting in implications for access to care. This rapid review summarizes how this knowledge has evolved in recent years.

RECENT FINDINGS

The number of articles on patient financial burden is increasing, suggesting awareness about the growing impact of economic burden on patients. This is particularly evident when discussing out-of-pocket costs, and lost work for patients/caregivers. However, there is an increasing focus on 'foregone care' and 'financial distress'. Additionally, emerging literature is examining policies and approaches to screen and/or mitigate these patient financial risks, thereby improving access to care. There is also increasing focus on populations that shoulder a disproportionate financial burden, including ethnic minorities (blacks, Asians, Latinos) as well as those with lower socioeconomic status. Additionally, there is evidence that this burden also affects the middle class.

SUMMARY

As healthcare budgets become stretched, especially during a pandemic, supportive programs benefiting the less fortunate often shrink, which impacts access to care. The emerging research on strategies with government or institutions to mitigate these burdens and access issues are both welcome and needed.

Out-of-pocket costs associated with head and neck cancer treatment

Background

Out‐of‐pocket costs (OOPC) associated with treatment have significant implications on quality of life and survival in cancer patients. Head and neck cancer patients face unique treatment‐related challenges, but to date OOPC have been understudied in this population.

Aims

This study aims to identify and measure OOPC for patients with head and neck cancer (HNC) in Ontario.

Methods

HNC patients between 2015 and 2018 at Princess Margaret Cancer Centre in Toronto were recruited. Participants completed OOPC questionnaires and lost income questions during radiation, post‐surgery, and 3, 6, 12, and 24 months after completion of treatment. Associations between OOPC and treatment modality and disease site were tested with multivariable hurdle regression.

Results

A total of 1545 questionnaires were completed by 657 patients. Median estimated OOPC for the total duration of treatment for participants undergoing chemoradiation was $1452 [$0–14 616], for surgery with adjuvant radiation or chemoradiation (C/RT) was $1626, for radiation therapy alone was $635, and for surgery alone was $360. The major expenses for participants at the mid‐treatment time‐point was travel (mean $424, standard error of the mean [SEM] $34) and meals, parking, and accommodations (mean $617, SEM $67). In multivariable analysis, chemoradiation, surgery with C/RT, and radiation were associated with significantly higher OOPC than surgery alone during treatment (791% higher, p < .001; 539% higher, p < .001; 370% higher, p < .001 respectively) among patients with non‐zero OOPC. Participants with non‐zero OOPC in the laryngeal cancer group paid 49% lower OOPC than those with oropharyngeal cancers in adjusted analysis (p = .025).

Conclusions

Patients undergoing treatment for HNC pay significant OOPC. These costs are highest during treatment and gradually decrease over time. OOPC vary by patient demographics, clinical factors, and, in particular, treatment modality.

Emerging Understanding About the Impact of Financial Toxicity Related to Cancer: Canadian Perspectives

OBJECTIVE

This article offers an overall summary of the current situation concerning cancer-related financial toxicity from the perspective of Canadian patents and survivors. The focus is on describing the financial effects experienced by the patient and survivor and family, which they attribute to the cancer diagnosis, treatment, and other factors that contribute to their financial distress.

DATA SOURCES

The information was drawn from peer-reviewed research literature generated by Canadian researchers regarding out-of-pockets costs, loss of income, and the impact of financial burden over the past 2 decades. Priority was given to understanding what patients and survivors and caregivers perceived as financial burden and distress (stress and strain).

CONCLUSION

Canadian patients and family members reported financial burden (out-of-pocket costs, loss of income) and financial distress following the diagnosis and treatment of cancer. Heightened distress from financial burden was reported between 38% and 71% within various samples. Patients and survivors indicated the distress and challenges managing the financial situation had a profound impact on their everyday living and quality of life. Many were surprised by the increased costs, given the county's universal health care system. Baseline financial status, competency in managing finances, and lost wages were significant factors in the distress experienced by patients and family members.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses need to be aware of financial toxicity as a potential side effect of cancer. It may emerge during treatment but can extend well beyond the end of treatment. Early screening and assessment followed by dialogue about the potential impact with patients and family members is important. Routine monitoring of distress related to financial toxicity should be part of ongoing care with appropriate referral to relevant recourses as needed.

Correlates of financial toxicity in adult cancer patients and their informal caregivers

BACKGROUND

Financial toxicity is commonly reported by cancer patients, but few studies have assessed caregiver perceptions. We aimed to validate the modified Comprehensive Score for Financial Toxicity (COST) in cancer caregivers, identify factors associated with financial toxicity in both patients and caregivers, and assess the association of caregiver financial toxicity with patient and caregiver outcomes.

METHODS

Using a convenience sampling method, 100 dyads of adult cancer patients and a primary caregiver visiting outpatient oncology clinics (Jan-Sep 2019) were recruited. We assessed the internal consistency and convergent and divergent validity of the modified COST. Multivariable analyses identified correlates of financial toxicity. Association of financial toxicity with care non-adherence, lifestyle-altering behaviors (e.g., home refinance/sale, retirement/saving account withdrawal), and quality of life (QOL) was investigated.

RESULTS

Recruited patient vs. caregiver characteristics were as follows: mean age: 60.6 vs. 56.5; 34% vs. 46.4% female; 79% vs. 81.4% white. The caregiver COST measure demonstrated high internal consistency (Cronbach α = 0.91). In patients, older age (B, 0.3 [95% CI, 0.1-0.4]) and higher annual household income (B, 14.3 [95% CI, 9.3-19.4]) correlated with lower financial toxicity (P < 0.05). In caregivers, lower patient financial toxicity (B, 0.4 [95% CI, 0.2-0.6]) and cancer stages 1-3 (compared to stage 4) (B, 4.6 [95% CI, 0.4-8.8]) correlated with lower financial toxicity (P < 0.05). Increased caregiver financial toxicity correlated with higher care non-adherence in patients, increased lifestyle-altering behaviors, and lower QOL in patients and caregivers (P < 0.05).

CONCLUSION

The COST measure can also be used to assess caregiver financial toxicity. Caregivers' financial toxicity was associated with negative outcomes for both dyad members.

A Survey of Potentially Modifiable Patient-Level Factors Associated with Self-Report and Objectively Measured Adherence to Adjuvant Endocrine Therapies After Breast Cancer

PURPOSE

Despite the efficacy of adjuvant endocrine therapy (AET) in reducing breast cancer recurrence and mortality, suboptimal AET adherence is common and hence an important clinical issue among breast cancer survivors. Delineating potentially modifiable patient-level factors associated with AET adherence may support the development of successful adherence-enhancing interventions.

PATIENTS AND METHODS

The present study included 133 breast cancer survivors prescribed AET recruited from a cancer pharmacy. Women completed a baseline questionnaire examining psychosocial factors and self-reported adherence and consented to their prescription records being monitored for the proceeding 12 months to ascertain proportion of days covered (PDC), an objective measure of adherence. Regression analyses were used to identify the factors most strongly associated with both self-reported and objective adherence. Exploratory moderation analyses examined whether factors were differentially associated with adherence based on AET type (aromatase inhibitors or tamoxifen).

RESULTS

Adherence was high in this sample (PDC over 12 months was 95%). Side effect severity was most strongly associated with self-reported adherence, followed by self-efficacy, and medication/healthcare system-related barriers. Medication/healthcare system-related barriers was the only factor that uniquely predicted objective adherence. Within medication/healthcare system-related barriers, fear of side effects was most strongly associated with both measures of adherence. There were no significant interactions between AET type and potentially modifiable factors in predicting self-reported or objective adherence.

CONCLUSION

Side effects, reactions to side effects, and self-efficacy may represent modifiable targets through which AET adherence can be improved. Associations between potentially modifiable factors and adherence did not vary by AET type, despite distinct side-effect profiles.
