Background

The number of cancer survivors (defined as anyone with a history of cancer, from the time of diagnosis onward) [1] in the USA is projected to reach 18.1 million by 2020, with an associated 39 % increase in cancer-related treatment costs [2]. Escalating treatment costs, however, represent only one aspect of cancer survivors’ economic burden, which also frequently includes reduced income due to work limitations, and other “hidden” treatment-related costs such as transportation and childcare expenses [35].

Together, medical expenses, reduced income due to work limitations, and other hidden costs can lead to financial distress [6]. Indeed, cancer survivors are at increased risk of financial hardship and medically related bankruptcy even when insured [610]. A recent study in Washington State found that cancer survivors were 2.65 times more likely to file for bankruptcy compared to those without cancer [10]. In a nationally representative sample, recently diagnosed and previously diagnosed cancer survivors had annual excess economic burdens of over $16,000 and $4000, respectively per survivor, over and above the annual burden of individuals without cancer [11]. Importantly, those experiencing financial distress are more likely to delay or forgo needed medical care—including needed cancer treatments [6, 12]—and are more likely to experience adverse health outcomes, such as anxiety, depression, and poor health-related quality of life [6, 1316]. Accordingly, national policy recommendations include monitoring and support for financial distress in the growing population of cancer survivors [17].

Despite recent research and policy attention to the issue of financial distress, little is known about the full scope of financial and work-related burden among cancer survivors. Many previous studies of financial and work-related burden in cancer survivors have limited generalizability given small, focused samples in single institutions or among those with a specific type of cancer [3, 6, 9, 14]. Previous population-based studies have generally analyzed expenditures and are limited in their ability to account for indirect costs and other factors that impact the overall financial burden on cancer survivors or use very broad measures of perceived financial burden rather than specific measures such as debt or bankruptcy [4, 5, 8, 11, 16, 18, 19]. A recent systematic review of studies on cancer-related financial distress identified only four US studies reporting the prevalence of financial distress among adult cancer survivors, most of which were conducted at single institutions and focused on subgroups of cancer survivors [12].

The recently released Experiences with Cancer Survivorship Supplement to the Medical Expenditure Panel Survey offers a unique opportunity to improve our knowledge about the overall burden experienced by cancer survivors in the USA [20]. To address gaps in existing literature, we take advantage of these newly available data to examine work and financial burden as reported by cancer survivors in a large, nationally representative sample that included survivors of all cancer types. We produce current national estimates of financial distress and work modifications among cancer survivors and examine related disparities, providing information that researchers, clinicians, and policymakers can use to develop risk-stratified interventions to address work and financial concerns.

Methods

Data source

Data were derived from the 2011 Medical Expenditure Panel Survey Household Component (MEPS-HC) and Experiences with Cancer Survivorship Supplement (ECSS). MEPS-HC is an annual, national survey conducted by the Agency for Healthcare Research and Quality (AHRQ) in a subsample of individuals from the previous year’s National Health Interview Survey (NHIS). MEPS-HC includes individuals of all ages, with all insurance types, and collects information on sociodemographic and health characteristics, as well as medical expenditures and service use [21]. In 2011, cancer survivors identified in NHIS were oversampled and completed the ECSS—a self-administered questionnaire co-developed by the National Cancer Institute (NCI), American Cancer Society (ACS), Centers for Disease Control and Prevention (CDC), National Institutes of Health (NIH), and LIVESTRONG—to provide national estimates of psychosocial, financial, work-related, and other aspects of cancer burden [20, 22]. Response rates for the 2011 MEPS-HC and ECSS were 59.4 and 91 %, respectively [23, 24].

Sample

Eligible subjects included adult (≥18 years) cancer survivors (defined as having a history of cancer from time of diagnosis onward) who completed the 2011 ECSS (n = 1419). We excluded individuals who reported only a history of non-melanoma skin cancer for consistency with prior work, and because these cancers rarely are fatal or require treatment comparable with that of other cancers [11]. After excluding individuals who were missing data on the dependent variables or who reported only non-melanoma skin cancers, the analysis sample included 1209 cancer survivors. Analysis of work modifications was limited to the subpopulation who reported working at any point during their cancer treatment (n = 616).

Financial and work concerns

Outcomes included self-reported financial and work concerns. MEPS questions about financial concerns included asking if, due to cancer, the respondent or a family member (1) incurred debt or borrowed money, (2) filed for bankruptcy, (3) was unable to cover the costs of medical care visits, (4) their families made other financial sacrifices, or (5) worried about paying large medical bills. Participants were coded as having a financial difficulty if they answered “yes” to experiencing debt, bankruptcy, or an inability to cover medical costs. They were coded as having a financial worry if they answered “yes” to making other financial sacrifices or worrying about medical bills. Work concern questions included asking if, due to cancer, the respondent (1) changed to a less demanding job, (2) retired earlier than planned, (3) delayed retirement, (4) took unpaid time off of work, or (5) took extended leave from work. Participants were coded as having made a long-term work modification if they answered “yes” to changing to a less demanding job, delaying, or taking early retirement. They were coded as having made a short-term work modification if they took extended or unpaid leave from work. Work concern variables were examined in the subpopulation of cancer survivors who reported working at any point since cancer diagnosis.

Predictors

Sociodemographic and health variables relevant to identifying disparities in work and financial outcomes were included as predictors in our models, including sex, race/ethnicity, marital status, insurance status, health status, residence of survivor (i.e., non-metropolitan service area [non-msa] versus metropolitan service area [msa]), income as a percentage of the federal poverty level, and years of education. In general, groups that tend to have better health outcomes were assigned as the reference groups for predictor variables in order to highlight disparities. The models also controlled for potentially confounding variables, including age at interview, age at cancer diagnosis, treatment status (currently in active treatment versus not in active treatment), and region (West, Midwest, and Northeast, versus South).

Because age at interview and age at cancer diagnosis both have a potentially non-linear relationship with financial and work concerns, quadratic and cubic terms for these variables were tested in the logistic regression models and retained if significant.

Statistical analysis

All analyses were conducted using Stata 12 (College Station, TX). Frequencies and proportions of all variables were calculated. Population proportions and 95 % confidence intervals were estimated for all financial and work-related outcomes. However, predictive models examined only financial difficulty and long-term work modifications. These outcomes were selected to provide more informative results because financial difficulties are more concrete than financial worries, and long-term work modifications are a less ambiguous measure of work impact than short-term work modifications (i.e., short-term work modifications could arguably be negative or positive outcomes based on personal preference). Logistic regression was used to model binary measures of financial difficulties and long-term work modifications (i.e., having any financial difficulty or work modification) as functions of the predictors. Odds ratios (OR) were calculated with corresponding 95 % confidence intervals (95 % CI) with statistical significance set at p < 0.05. Survey weights were applied, and Stata survey commands were used in all analyses to account for the complex survey design and produce national estimates generalizable to the US civilian, non-institutionalized population self-reporting as having been diagnosed with or treated for cancer as an adult.

The work and financial concern questions were not assessed within any specific time frame (e.g., within the last year). Therefore, we stratified all regression models by either age at interview or treatment status to account for potential differences in the measured effects by these variables. Models of work modifications were limited only to survivors who reported working at any point from cancer diagnosis to the survey interview date. In cancer care, economic impact varies substantially by phase of treatment, following a U-shaped curve that reflects greater costs of care during initial treatment and again towards end-of-life care [25]. In addition, cancer-related work limitations may have different effects on employment of younger survivors than among older survivors who are eligible for Medicare or Social Security benefits [10, 26]. Accordingly, we focused on identifying predictors within these high-risk groups and present models of financial distress and long-term work modifications only among those who were less than age 65 years at interview or who were currently in active treatment.

Results

Sample characteristics

Our sample of cancer survivors included a higher proportion of women (58.1 %) compared to men. Over half were age 65 years and older at interview (54.4 %) versus less than age 65 years. The majority of cancer survivors were white, non-Hispanic (84.4 %). 59.4 % reported having good/fair/poor health versus excellent/very good health. 56.7 % reported being married. One third reported having ≥16 years of education (33.5 %). Less than half of survivors reported an adjusted family income ≥400 % of FPL (43.0 %). About two thirds reported having private insurance (68.2 %). Regarding treatment status, survivors in active treatment comprised the smallest proportion of the sample (18.1 %), followed by those <5 years posttreatment (30.9 %), with the largest proportion ≥5 years posttreatment (51.0 %). The most commonly reported cancer sites were breast (20.3 %) and prostate (16.5 %). Just over half of the survivors in our sample were diagnosed with cancer between the ages of 40 and 65 years (53.0 %) and almost a third at age 65 years or older (29.9 %) (Table 1).

Financial concerns

Among all cancer survivors, 33.2 % reported having at least one financial concern (not shown in tables), 17.9 % reported a financial difficulty, and 28.3 % reported a financial worry (Table 2). A consistently higher proportion of survivors in active treatment had financial concerns compared to those not in active treatment, with significant differences for any financial worry (46.5 versus 24.8 %), worry about paying medical bills (41.6 versus 21.8 %), and financial sacrifice (18.2 versus 9.0 %) (Table 2). Significantly higher proportions of survivors less than age 65 years at interview reported all measures of financial concerns except bankruptcy compared to those age 65 years or older at interview (Table 2), including overall measures of financial difficulty (27.3 versus 10.0 %), and financial worry (39.3 versus 19.1 %) (Table 2). While differences in the proportion reporting bankruptcy were not statistically significant, the proportion of survivors less than age 65 years at interview reporting this outcome was higher than in any other subgroup (2.3 versus 1.4 % [age ≥65 years at interview]; 1.8 % [all survivors]) (Table 2).

Work modifications

Among cancer survivors who reported working, 44.0 % made at least one work modification due to cancer (not shown in tables), including long-term work modifications (15.3 %) and short-term work modifications (39.3 %) (Table 2). The only statistically significant difference between those in active treatment versus those not in active treatment was a lower proportion of survivors who changed to a less demanding job (0.3 versus 3.9 %) (Table 2). A significantly greater proportion of survivors less than age 65 years at interview reported making short-term work modifications, including extended leave of absence (30.7 versus 24.0 %) or unpaid leave of absence (24.0 versus 13.4 %) (Table 2).

Fully adjusted regression models

Survivors in active treatment

In fully adjusted logistic regression models among survivors currently in active treatment, significant predictors of having any financial difficulty (i.e., debt, bankruptcy, or inability to pay bills) included race/ethnicity other than white, non-Hispanic [OR = 8.0; 95 % CI 2.2–28.4]); good/fair/poor health status [OR = 3.8; 95 % CI 1.0–14.2]; income <200 % of FPL [OR = 15.7; 95 % CI 2.6, 95.2] or between 200 and 400 % of FPL [OR = 8.2; 95 % CI 1.3–52.4]; and residing in a non-metropolitan service area [OR = 6.4; 95 % CI 1.6–25.0] (Table 3). Among survivors currently in active treatment, the only significant predictor of making a long-term work modification (i.e., changing to a less demanding job, taking delayed or early retirement) was good/fair/poor health status [OR = 10.4; 95 % CI 2.0–54.8] (Table 3).

Survivors less than age 65 years at interview

Among survivors less than age 65 years at interview, significant predictors of having a financial difficulty included good/fair/poor health status [OR = 2.4; 95 % CI 1.4–4.1] and between 12 and 16 years of education [OR = 1.9; 95 % CI 1.1–3.6] (Table 4).

Table 4 Logistic regression models for adult cancer survivors less than 65 years of age (n = 587), Medical Expenditures Panel Survey and Experiences with Cancer Survivorship Supplement 2011

Among survivors less than age 65 years at interview, significant predictors of making a long-term work modification included good/fair/poor health status [OR = 4.1; 95 % CI 1.6–10.2], being married [OR = 2.2; 95 % CI 1.0–4.7], and being uninsured [OR = 3.5; 95 % CI 1.3–9.3] or publicly insured [OR = 9.0; 95 % CI 3.3–24.4] (Table 4).

The effect of age

Predicted marginal effects for age at interview were calculated post-estimation for models in which age at interview was a significant predictor. Age at interview was not a significant predictor of long-term work modifications for either subpopulation but had a significant curvilinear relationship with the odds of financial difficulty for survivors less than age 65 years and survivors currently in active treatment.

For survivors currently in active treatment, the odds of financial difficulty were minimal for younger patients, but began increasing in the mid-40s, peaking at approximately 60 years of age (Fig. 1). For survivors less than age 65 years at interview, the odds of financial difficulty were highest among the youngest survivors, leveling off at approximately age 30 and decreasing at approximately age 62 (Fig. 2).

Discussion

In a nationally representative sample, we found that one in three cancer survivors experienced financial concerns and nearly half of employed cancer survivors made work modifications. Our results are consistent with prior reports showing that cancer survivors face productivity losses and heavy financial burdens as a result of their disease and related treatment [3, 4, 6, 813, 18, 19]. Previous estimates of the proportion of cancer survivors with financial distress have ranged from 14–78 % [12]. The proportion of cancer survivors filing for bankruptcy—just one of several measures of financial distress we examined—has been previously been estimated at 2.2 % and is similar to findings in our study [10]. While few studies have used comparable measures of work modifications, a recent national study estimated that about 30 % of cancer survivors experience limitations in work or usual activities due to physical health [8]. We provide estimates that both support and extend current literature by highlighting cancer survivors’ experiences of work and financial burden, such as borrowing money or delaying retirement. Prior studies have, in contrast, predominantly used broad measures (e.g., perception of financial distress) or purely quantitative measures (e.g., out of pocket expenditures and missed work days) that, while important, do not adequately characterize the impact of disease and treatment-related costs on survivors’ lives.

We identified substantial disparities in financial difficulties, with survivors who were of race/ethnicity other than white, non-Hispanic, had incomes <400 % of FPL, who lived in non-metropolitan areas, or who reported good/fair/poor health at increased risk among those in active treatment, as well as survivors with good/fair/poor health status and between 12 and 16 years of education among those less than 65 years of age at interview. The disparities we identified persisted despite controlling for insurance, suggesting that survivors in these subgroups experience financial problems even when insured [3, 9]. The disparities we identified for financial difficulties are congruent with previous studies, which have consistently identified predictors of both financial hardship and productivity losses as younger age, minority race/ethnicity, lower income, and active treatment status/recent diagnosis [6, 7, 9, 10, 12, 13, 16].

Our study contributes several novel findings with respect to financial burden among cancer survivors. Among survivors less than age 65 years at interview, we found significantly higher odds of financial difficulty for those who had between 12 and 16 years of education, roughly equivalent to having some college, but not a college degree. This finding suggests that individuals with this upper-middle level of education may have jobs that place them at particular risk for medically related financial problems in this age group, perhaps a result of underinsurance or other competing financial burdens (e.g., childcare, student loans). Among survivors in active treatment, we found significantly higher odds of financial difficulty associated with residence in non-metropolitan service areas—a finding that points to the need for further research to examine the drivers of financial distress for patients in rural settings.

Our results with respect to work modifications also provide novel contributions. We found, among survivors less than age 65 years at interview, that those who are married, uninsured, or publicly insured have higher odds of making a long-term work modification. Within this age group, private insurance is largely tied to employment, and individuals with public insurance may be eligible for reasons related to work disability. Alternatively, these findings may be a result of the need for younger survivors with private insurance to maintain employment. Individuals who are married (and therefore eligible for insurance through a spouse) or who lack private insurance could potentially make long-term employment changes without affecting insurance coverage. Importantly, these findings come from a survey conducted in 2011 before implementation of the Affordable Care Act (ACA). It will be important to monitor how ACA implementation impacts work and financial problems for cancer survivors in light of potentially improved access to affordable insurance coverage that is not dependent on employment.

Lastly, we provide novel estimates that describe the relationship between age and the probability of experiencing financial difficulties. Our findings point to the complex relationship between age and financial burden and suggest that while older patients may experience greater financial challenges during the initial treatment phase, financial burden for younger patients may increase over time and extend into the posttreatment phase. Possibly, these long-term financial effects occur because younger survivors face not only treatments costs but also longer-term effects on productivity and income. Future studies, ideally using longitudinal designs, are warranted to more fully understand the work and financial experiences of survivors across the life course.

Many patients report a desire to discuss treatment costs, and practice guidelines suggest that financial discussions are important to high-quality care [27, 28]. However, evidence suggests that conversations about costs happen infrequently, and little is known about barriers and facilitators for these conversations [2830]. Patients might benefit from discussion of financial and work concerns, particularly when alternative treatment options may provide similar benefit at lower cost [27, 31]. However, such conversations are sensitive—doctors and patients frequently believe the other should be responsible for initiating such discussions [32], and even patients who wish to be aware of the costs of care may prefer that providers not consider costs in decision making, fearing that they will receive subpar treatment if they have a limited ability to pay [33, 34]. Survivors experiencing difficulties might benefit from programs that assist with financial and employment issues; however, such programs are relatively few. The high prevalence of financial and work concerns in our study suggests the need for additional support and program development in this area. Further research and policy attention to work and financial concerns might maximize impact by focusing on groups at higher risk of financial and work problems, such as younger survivors, minorities, those with lower incomes or without private insurance, those living in more rural service areas and those with worse overall health.

Limitations

Our study has several important limitations. First, our findings must be interpreted cautiously in light of the imprecise time frame around the work and financial burden questions in the ECSS. Cancer survivors reported whether or not they ever experienced these burdens due to cancer, but not within a specific time period (e.g., during the past 12 months). Therefore, differences in outcomes are potentially confounded by age, poor recall of past events, or differences in healthcare policies affecting costs and employment benefits for long-term versus recent survivors. We minimized this confounding by controlling for both current age and age of cancer diagnosis in all models and by stratifying the models by treatment status and age. Second, because the financial and work-related questions were included in a survey supplement administered only to cancer survivors, it is not possible to compare these outcomes between individuals with and without a history of cancer. Third, the MEPS sample includes only civilian, non-institutionalized individuals and excludes those in nursing homes, long-term care, or other institutions. This may have caused us to underestimate work and financial burden, since those who are institutionalized are likely to be in worse health and have greater treatment-related expenses. Underestimates may also have resulted due to the self-reported nature of survey responses and the stigma related to reporting certain aspects of work or financial distress [26]. Fourth, the 59.4 % response rate may reflect some level of sampling bias in the MEPS if there are unmeasured characteristics associated with choosing to respond to the survey versus choosing not to respond. Finally, the relatively small sample size of the MEPS ECSS may have contributed to wide confidence intervals for some of our estimates, overlapping confidence intervals in the analysis of the effect of age on financial difficulties, and may have limited our power to detect important disparities in some subgroups.

Conclusions

Our study yields important new insights about the scope of work and financial burden among cancer survivors in the USA by providing current national estimates of work modifications and financial distress in this growing population. Our findings point to the urgent need for attention to the work and financial impact of treatment on cancer survivors from active treatment through long-term survivorship.
