A retrospective study of patients' out-of-pocket costs for granulocyte colony-stimulating factors

The Out-of-Pocket Cost Burden of Cancer Care-A Systematic Literature Review

BACKGROUND

Out-of-pocket costs pose a substantial economic burden to cancer patients and their families. The purpose of this study was to evaluate the literature on out-of-pocket costs of cancer care.

METHODS

A systematic literature review was conducted to identify studies that estimated the out-of-pocket cost burden faced by cancer patients and their caregivers. The average monthly out-of-pocket costs per patient were reported/estimated and converted to 2018 USD. Costs were reported as medical and non-medical costs and were reported across countries or country income levels by cancer site, where possible, and category. The out-of-pocket burden was estimated as the average proportion of income spent as non-reimbursable costs.

RESULTS

Among all cancers, adult patients and caregivers in the U.S. spent between USD 180 and USD 2600 per month, compared to USD 15-400 in Canada, USD 4-609 in Western Europe, and USD 58-438 in Australia. Patients with breast or colorectal cancer spent around USD 200 per month, while pediatric cancer patients spent USD 800. Patients spent USD 288 per month on cancer medications in the U.S. and USD 40 in other high-income countries (HICs). The average costs for medical consultations and in-hospital care were estimated between USD 40-71 in HICs. Cancer patients and caregivers spent 42% and 16% of their annual income on out-of-pocket expenses in low- and middle-income countries and HICs, respectively.

CONCLUSIONS

We found evidence that cancer is associated with high out-of-pocket costs. Healthcare systems have an opportunity to improve the coverage of medical and non-medical costs for cancer patients to help alleviate this burden and ensure equitable access to care.

Costs of cancer along the care continuum: What we can expect based on recent literature

BACKGROUND

Cancer costs should be discussed by patients and providers, but information is not readily available. Results from recently published studies (in the last 5 years) on direct and indirect cancer costs may help guide these discussions.

METHODS

The authors reviewed studies published between 2013 and 2017 that reported direct health care costs and indirect (productivity losses) costs. The annual mean total and net costs of cancer were summarized for all payers and for survivors only by age (ages 18-64 and ≥65 years), by phase of care (initial [ie, 12 months from diagnosis], continuing, and end-of-life [ie, 12 months before death]), or for recently diagnosed (within 1-2 years of diagnosis) and longer term survivors.

RESULTS

For all payers combined, costs for cancers like breast, prostate, colorectal, and lung cancers were $20,000 to $100,000 in the initial phase, $1000 to $30,000 annually in the continuing phase, and ≥$60,000 in the end-of-life phase. Annual out-of-pocket costs to recently diagnosed survivors were >$1000 for medical care and time costs, approximately $2000 for productivity losses, and from $2500 to >$4000 for employment disability, depending on age. For longer term survivors, the cost of medical care was approximately $1500 for older survivors and $747 for younger survivors, time costs were $831 to $955 for older survivors and $459 to $630 for younger survivors, and productivity losses were approximately $800. Disability among long-term survivors was similar to that among short-term survivors. Limitations of the reviewed studies included older data and under-representation of higher cost cancers.

CONCLUSIONS

Frequently updated cost information for all cancer types is needed to guide discussions of anticipated short-term and long-term cancer-related costs with survivors. Cancer 2018;000:000-000. © 2018 American Cancer Society.

Annual patient and caregiver burden of oncology clinic visits for granulocyte-colony stimulating factor therapy in the US

OBJECTIVE

Prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs) is indicated for chemotherapy patients with a significant risk of febrile neutropenia. This study estimates the annual economic burden on patients and caregivers of clinic visits for prophylactic G-CSF injections in the US.

METHODS

Annual clinic visits for prophylactic G-CSF injections (all cancers) were estimated from national cancer incidence, chemotherapy treatment and G-CSF utilization data, and G-CSF sales and pricing information. Patient travel times, plus time spent in the clinic, were estimated from patient survey responses collected during a large prospective cohort study (the Prospective Study of the Relationship between Chemotherapy Dose Intensity and Mortality in Early-Stage (I-III) Breast Cancer Patients). Economic models were created to estimate travel costs, patient co-pays and the economic value of time spent by patients and caregivers in G-CSF clinic visits.

RESULTS

Estimated total clinic visits for prophylactic G-CSF injections in the US were 1.713 million for 2015. Mean (SD) travel time per visit was 62 (50) min; mean (SD) time in the clinic was 41 (68) min. Total annual time for travel to and from the clinic, plus time at the clinic, is estimated at 4.9 million hours, with patient and caregiver time valued at $91.8 million ($228 per patient). The estimated cumulative annual travel distance for G-CSF visits is 60.2 million miles, with a total transportation cost of $28.9 million ($72 per patient). Estimated patient co-pays were $61.1 million, ∼$36 per visit, $152 per patient. The total yearly economic impact on patients and caregivers is $182 million, ∼$450 per patient.

LIMITATIONS

Data to support model parameters were limited. Study estimates are sensitive to the assumptions used.

CONCLUSIONS

The burden of clinic visits for G-CSF therapy is a significant addition to the total economic burden borne by cancer patients and their families.

The implications of out-of-pocket cost of cancer treatment in the USA: a critical appraisal of the literature

Advances in cancer diagnosis and treatment have led to increased societal costs and out-of-pocket patient cost. We reviewed the literature on the impact of out-of-pocket cancer care costs on the patient experience, and described efforts made to address these costs. A critical appraisal of articles published in the USA from 2004 to 2014 was performed. The literature revealed that even insured patients receiving anticancer therapy are vulnerable to financial distress, which can impel patients to borrow money, deplete their savings, or engage in cost-coping strategies including nonadherence to prescribed treatment. Additional research is required to define financial distress risk factors, patient-physician communication of the costs of cancer care, and supportive care models for patients and survivors with substantial financial burdens.

Discrete choice experiment to estimate breast cancer patients' preferences and willingness to pay for prophylactic granulocyte colony-stimulating factors

OBJECTIVES

Rising out-of-pocket costs for cancer patients have increased shared decision making. Clinical guidelines recommend prophylactic granulocyte colony-stimulating factor (G-CSF) for patients receiving chemotherapy with a 20% or greater risk of febrile neutropenia. A discrete choice experiment was conducted to explore breast cancer patients' preferences and willingness to pay (WTP) for prophylactic G-CSF to decrease the risk of chemotherapy-induced febrile neutropenia.

METHODS

An online discrete choice experiment questionnaire survey of a national US convenience sample of self-reported breast cancer patients with prior chemotherapy treatment was conducted. Sixteen paired G-CSF treatment scenarios, each with four attributes (risk of disruption to chemotherapy schedule due to low white blood cell counts, risk of developing an infection requiring hospitalization, frequency of administration, and total out-of-pocket cost) were presented with a follow-up "no treatment" option. Participant preferences and WTP out of pocket were estimated by logistic regression.

RESULTS

Participants (n = 296) preferred G-CSF regimens with lower out-of-pocket costs, lower risk of chemotherapy disruption, lower risk of infection, and greater convenience (one G-CSF injection per chemotherapy cycle). Participants' WTP was $1076 out of pocket per cycle to reduce the risk (high to low) of disrupting their chemotherapy schedule, $884 per cycle to reduce the risk (24% [high] to 7% [low]) of infection, and $851 per cycle to decrease the number of G-CSF injections (11 to 1) per cycle.

CONCLUSIONS

Participants highly valued specific features of prophylactic G-CSF treatment including maintaining their chemotherapy schedule, lowering their risk of infection, and reducing the number of injections. Physicians should consider patient preferences to inform the best treatment choices for individual patients.
