Burden of Treatment-Induced Peripheral Neuropathy in Patients with Multiple Myeloma in Sweden.

INTRODUCTION: Treatment-induced peripheral neuropathy (TIPN) is a complication of multiple myeloma (MM) treatment. OBJECTIVE: This real-world, retrospective study used electronic medical record (EMR) data from 3 Swedish clinics to assess the occurrence and economic burden of TIPN in patients with MM. METHODS: Eligible patients had an MM diagnosis in the Swedish Cancer Registry between 2006 and 2015 and initiated treatment during that period. Follow-up was until last EMR visit, death, or study end (April 2017). The current analyses included patients receiving bortezomib, lenalidomide, carfilzomib, or thalidomide at any treatment line. To discern healthcare resource utilization (HCRU) and costs associated with TIPN from other causes, patients with TIPN were matched with those without on baseline characteristics, treatment, and line of therapy. All analyses were descriptive. RESULTS: Overall, 457 patients were included; 102 (22%) experienced TIPN. Patients experiencing TIPN during first-line treatment mostly received bortezomib-based regimens (n = 48/57 [84%]); those with TIPN during second- and third/fourth-line treatment mostly received lenalidomide/thalidomide-based regimens (19/31 [61%], 8/14 [57%], respectively). Patients with TIPN had higher HCRU/costs than those without TIPN (mean differences in hospital outpatient visits: 5.2, p = 0.0031; total costs per patient-year: EUR 17,183, p = 0.0007). CONCLUSIONS: Effective MM treatments associated with a reduced incidence of TIPN could result in decreased healthcare expenditure.

Patient and caregiver productivity loss and indirect costs associated with cardiovascular events in Europe.

AIMS: The aim of this study was to estimate patient and caregiver productivity loss and indirect costs following an acute coronary syndrome (ACS) or a stroke in Europe. METHODS: A cross-sectional study was conducted in seven European countries. A validated questionnaire was used during a cardiologist/neurologist visit 3-12 months post event. We included patients who returned to work ( ≥ 4 weeks prior to recruitment), given specific interest in presenteeism. Patient absenteeism, presenteeism and caregiver loss in the past four weeks were pro-rated to one year and combined with time-off due to initial hospitalisation/sick-leave. Hours lost were valued according to country labour cost (2018 euros). RESULTS: The analysis included 196 ACS (86% myocardial infarction) and 198 stroke (99% ischaemic, 77% modified Rankin Scale 0-1) patients. Mean age in ACS and stroke patients was 53 years, 86% and 78% respectively were men, 28% and 25% had previous cardiovascular event or established cardiovascular disease. Mean (country range) total productivity time loss was 70 (47-91) workdays for ACS and 68 (45-88) workdays for stroke (25% of annual workdays). Particularly, ACS patient lost 59 (37-79) workdays, and caregivers lost 11 (0-16) workdays, with total mean indirect cost per case €13,953 (€6641-23,160). After stroke, 56 (42-70) workdays were lost by patient plus 12 (3-20) days by caregiver, amounting to €13,773 (€10,469-20,215). Patients with previous events or established cardiovascular disease lost 80 (ACS) and 73 (stroke) workdays, costing €16,061 and €14,942 respectively. CONCLUSIONS: Our results suggest that lost productive time and indirect costs following ACS/stroke are substantial, with indirect costs comparable to direct costs.

Comparison of Recommendations and Use of Cardiovascular Risk Equations by Health Technology Assessment Agencies and Clinical Guidelines.

OBJECTIVES: To identify risk equations for cardiovascular diseases (CVDs) in primary and secondary prevention settings that are used or recommended by health technology assessment (HTA) organizations and in clinical guidelines (CGs). METHODS: A targeted literature review was conducted using a two-stage search strategy. First, HTA reviews of manufacturers' drug submissions, reports from established HTA organizations (Europe, Canada, and Australia), and CGs from countries with and without HTA organizations, including the United States, were identified. Documents published between September 30, 2006 and September 30, 2016, were examined for cardiovascular risk equations, recommendations, and commentaries. Next, publications associated with risk equations and cited by HTA and CG documents were retrieved. This literature was examined to extract commentaries and risk equation study characteristics. RESULTS: The review identified 47 risk equations, 25 in the primary CVD prevention setting (i.e., patients with no CVD history), including 5 for CVD prevention in diabetes and 22 solely in secondary prevention settings; 11 were identified for heart failure, 3 for stroke or transient ischemic attack, 2 for stable angina, and 11 for acute coronary syndrome or related conditions. A small set of primary prevention equations was found to be commonly used by HTAs, whereas secondary prevention equations were less common in HTA documents. CGs provided more risk equations as options than HTA documents. CONCLUSIONS: Although there is an abundance of risk equations developed for primary and secondary prevention, there remains a need for additional research to provide sufficient clinical and HTA guidance for risk estimation, particularly in high-risk or secondary prevention settings.

Methods for estimating costs in patients with hyperlipidemia experiencing their first cardiovascular event in the United Kingdom.

AIMS: Methods for integrating external costs into clinical databases are not well-characterized. The purpose of this research was to describe and implement methods for estimating the cost of hospitalizations, prescriptions, and general practitioner and specialist visits used to manage hyperlipidemia patients experiencing cardiovascular (CV) events in the United Kingdom (UK). METHODS: This study was a retrospective cohort study using the Clinical Practice Research Datalink and Hospital Episode Statistics data. Costs were incorporated based on reference costs from the National Health Service, and labor costs from the Personal Social Services Research Unit. The study population included patients seen by general practitioners in the UK from 2006-2012. Patients ≥18 years were selected at the time of their first CV-related hospitalization defined as myocardial infarction, ischemic stroke, heart failure, transient ischemic attack, unstable angina, or revascularization. To be included, patients must have received ≥2 lipid-lowering therapies. Outcome measures included healthcare utilization and direct medical costs for hospitalizations, medications, general practitioner visits, and specialist visits during the 6-month acute period, starting with the CV hospitalization, and during the subsequent 30-month long-term period. RESULTS: There were 24,093 patients with a CV hospitalization included in the cohort. This study identified and costed 69,240 hospitalizations, 673,069 GP visits, 32,942 specialist visits, and 2,572,792 prescriptions, representing 855 unique drug and dose combinations. The mean acute period and mean annualized long-term period costs (2014£) were £4,060 and £1,433 for hospitalizations, £377 and £518 for GP visits, £59 and £103 for specialist visits, and £98 and £209 for medications. CONCLUSIONS: Hospital costs represent the largest portion of acute and long-term costs in this population. Detailed costing using utilization data is feasible and representative of UK clinical practice, but is labor intensive. The availability of a standardized coding system in the UK drug costing data would greatly facilitate drug costing.

Cost-effectiveness of Evolocumab in Patients With High Cardiovascular Risk in Spain.

PURPOSE: Our objective was to assess the cost-effectiveness of evolocumab in patients at high risk of cardiovascular (CV) events from the Spanish National Health System perspective. METHODS: A Markov model was used to assess the cost-effectiveness (incremental [∆] cost per ∆ quality-adjusted life-year [QALY]; or cost utility) of evolocumab plus standard of care (SoC; statins) versus SoC, assuming lifetime treatment. Cohorts with baseline LDL-C >100 mg/dL and familial hypercholesterolemia (FH) or CV event history (secondary prevention [SP]) were considered. Lifetime CV event rates were predicted either (1) using risk equations considering local risk factors (Spanish Familial Hypercholesterolemia Cohort Study) adjusted to reflect the increased risk of FH patients or (2) using CV event rates from local registries (Information System for the Development of Research in Primary Care) for SP patients. LDL-C relative reductions from evolocumab trials (Evolocumab 140 mg Q2W (bi-weekly) and 420 mg QM (monthly)) were converted into CV event reductions using rate ratios per millimole per liter (mmol/L; 38.67 mg/dL) from a meta-analysis of statin trials (Cholesterol Treatment Trialists' Collaboration). FINDINGS: Predicted 10-year/lifetime CV risks were 50%/95% (FH) and 62%/82% (SP) for SoC and 27%/83% (FH) and 44%/69% (SP) for evolocumab plus SoC. Predicted 10-year/lifetime major CV event risks were 42%/86% (FH) and 47%/67% (SP) for SoC and 21%/68% (FH) and 31%/52% (SP) for evolocumab plus SoC. Predicted per patient-year rates of non-fatal/fatal CV events were 2.2/0.8 (FH) and 1.1/0.6 (SP) for SoC and 1.2/0.6 (FH) and 0.7/0.5 (SP) for evolocumab plus SoC. Predicted CV event reductions per mmol/L were 17% (FH) and 15% (SP). Evolocumab treatment was associated with increased QALYs and costs compared with SoC (FH: ∆cost, €65,369; ∆QALY, 2.12; incremental cost-effectiveness ratio [ICER], €30,893; SP: ∆cost, €42,266; ∆QALY, 0.93; ICER, €45,340). IMPLICATIONS: Evolocumab plus to SoC may provide a cost-effective option for LDL-C lowering in FH and SP patients in Spain.

Characterization and cholesterol management in patients with cardiovascular events and/or type 2 diabetes in the Netherlands.

OBJECTIVE: To describe clinical characteristics and cholesterol management of patients with cardiovascular events (CVEs) and/or type 2 diabetes mellitus (T2DM) with high low-density lipoprotein cholesterol (LDL-C) > 1.8 mmol/L in the Netherlands. RESEARCH DESIGN AND METHODS: From the PHARMO Database Network a cross-sectional cohort was constructed. The descriptive study included patients on lipid modifying therapy (LMT) in 2009, classified as high cardiovascular risk based on a history of T2DM or CVE, with 2010 LDL-C levels above 1.8 mmol/L (2011 European Society of Cardiology [ESC] target). Sub-cohorts were created: T2DM + CVE from the T2DM cohort and multiple CVE from the CVE only cohort. MAIN OUTCOME MEASURES: Clinical characteristics and drug treatment were determined at the time of the last LDL-C measurement in 2010. RESULTS: Of 10,864 very high risk patients, 66% had T2DM, 37% of whom also had CVE. In the CVE only cohort (34%), 18% had multiple events. More regular check-ups skewed inclusion towards diabetes patients. T2DM vs. CVE cohort characteristics were: 53% vs. 63% male, 42% vs. 27% obese, 19% vs. 24% current smoker, 54% vs. 51% systolic blood pressure <140 mmHg, with similar proportions in the sub-cohorts. Proportions reaching the Dutch guideline LDL-C target of <2.5 mmol/L were 56% (T2DM), 57% (T2DM + CVE), 48% (CVE only) and 53% (multiple CVE only). Frequencies of high intensity dose statin (simvastatin ≥80 mg, atorvastatin ≥40 mg or rosuvastatin ≥20 mg) were 6% (T2DM), 9% (T2DM + CVE, CVE only) and 14% (multiple CVE only); 1-2% received additional ezetimibe and 3-5% received non-statin LMT only, including ezetimibe. CONCLUSION: Despite LMT, >40% of the patients above ESC target also failed to reach the less stringent Dutch target, even in the higher risk groups. Therefore, management of hypercholesterolemia after CVE or T2DM should be optimized to improve cardiovascular outcomes. There is substantial room for improving other cardiovascular risk factors.

Estimating the economic burden of cardiovascular events in patients receiving lipid-modifying therapy in the UK.

OBJECTIVES: To characterise the costs to the UK National Health Service of cardiovascular (CV) events among individuals receiving lipid-modifying therapy. DESIGN: Retrospective cohort study using Clinical Practice Research Datalink records from 2006 to 2012 to identify individuals with their first and second CV-related hospitalisations (first event and second event cohorts). Within-person differences were used to estimate CV-related outcomes. SETTING: Patients in the UK who had their first CV event between January 2006 and March 2012. PARTICIPANTS: Patients ≥18 years who had a CV event and received at least 2 lipid-modifying therapy prescriptions within 180 days beforehand. PRIMARY AND SECONDARY OUTCOME MEASURES: Direct medical costs (2014 £) were estimated in 3 periods: baseline (pre-event), acute (6 months afterwards) and long-term (subsequent 30 months). Primary outcomes included incremental costs, resource usage and total costs per period. RESULTS: There were 24 093 patients in the first event cohort of whom 5274 were included in the second event cohort. The mean incremental acute CV event costs for the first event and second event cohorts were: coronary artery bypass graft/percutaneous transluminal coronary angioplasty (CABG/PTCA) £5635 and £5823, myocardial infarction £4275 and £4301, ischaemic stroke £3512 and £4572, heart failure £2444 and £3461, unstable angina £2179 and £2489 and transient ischaemic attack £1537 and £1814. The mean incremental long-term costs were: heart failure £848 and £2829, myocardial infarction £922 and £1385, ischaemic stroke £973 and £682, transient ischaemic attack £705 and £1692, unstable angina £328 and £677, and CABG/PTCA £-368 and £599. Hospitalisation accounted for 95% of acute and 61% of long-term incremental costs. Higher comorbidity was associated with higher long-term costs. CONCLUSIONS: Revascularisation and myocardial infarction were associated with the highest incremental costs following a CV event. On the basis of real-world data, the economic burden of CV events in the UK is substantial, particularly among those with greater comorbidity burden.

Cost effectiveness of romiplostim for the treatment of chronic immune thrombocytopenia in Ireland.

BACKGROUND: Romiplostim, a thrombopoietin receptor agonist (TPOra), is a second-line medical treatment option for adults with chronic immune thrombocytopenia (ITP). Clinical trials have shown that romiplostim increases platelet counts, while reducing the risk of bleeding and, in turn, the need for costly rescue medications. AIMS: The objective of this study was to assess the cost effectiveness of romiplostim in the treatment of adult ITP in Ireland, in comparison with eltrombopag and the medical standard of care (SoC). METHODS: A lifetime treatment-sequence cost-utility Markov model with embedded decision tree was developed from an Irish healthcare perspective to compare romiplostim with eltrombopag and SoC. The model was driven by platelet response (platelet count ≥50 × 10(9)/L), which determined effectiveness and progression along the treatment pathway, need for rescue therapy (e.g. intravenous immunoglobulin [IVIg] and steroids) and risk of bleeding. Probability of response, mean treatment duration, average time to initial response and utilities were derived from clinical trials and other published evidence. Treatment sequences and healthcare utilization practice were validated by Irish clinical experts. Costs were assessed in for 2011 and included drug acquisition costs and costs associated with monitoring patients and management of bleeding, as available from published Irish reimbursement lists and other relevant sources. Deterministic and probabilistic sensitivity analyses were conducted. RESULTS: Romiplostim treatment resulted in an average of 20.2 fewer administrations of rescue medication (IVIg or intravenous steroids) over a patient lifetime than eltrombopag, and 29.3 fewer rescue medication administrations than SoC. Romiplostim was dominant, with cost savings of 13,258 and 22,673 and gains of 0.76 and 1.17 quality-adjusted life-years (QALYs), compared with eltrombopag and SoC, respectively. Romiplostim remained cost effective throughout a variety of potential scenarios, including short-term TPOra treatment duration (1 year). One-way sensitivity analysis showed that the model was most sensitive to variation in the cost of IVIg and use of romiplostim and IVIg. Probabilistic sensitivity analysis showed that romiplostim was likely to be cost effective in over 90 % of cases compared with eltrombopag, and 96 % compared with SoC at a willingness-to-pay threshold of 30,000 per QALY. CONCLUSIONS: Use of romiplostim in the ITP treatment pathway, compared with eltrombopag or SoC, is likely to be cost effective in Ireland. Romiplostim improves clinical outcomes by increasing platelet counts, reducing bleeding events and the use of IVIg and steroids, resulting in both cost savings and additional QALYs when compared with current treatment practices.

Hemoglobin level at initiation of darbepoetin alfa: impact on need for transfusion and associated costs in chemotherapy-induced anemia treatment in Europe.

PURPOSE: Erythropoiesis-stimulating agents can reduce red blood cell transfusion rates in patients developing anemia while receiving chemotherapy. We investigated potential cost savings from reduced transfusion rates in patients starting darbepoetin alfa (DA) at higher versus lower hemoglobin (Hb) levels. METHODS: Two systematic literature reviews were performed: transfusion outcomes in patients receiving DA stratified by baseline Hb level and costs of transfusion in Europe. Potential cost savings were calculated by multiplying the difference in transfusion rates between Hb levels by the midpoint of transfusion costs. RESULTS: Despite differences in baseline characteristics, treatment duration and analysis technique, the clinical studies (n = 8) showed that fewer transfusions were required when DA was initiated at higher versus lower Hb levels. The economic studies (n = 9) showed that 1 unit of transfusion ranged from 130 to 537 (2010-adjusted values). Cost savings from initiating DA at higher versus lower Hb levels were 503-2,226 (2 units transfused) and 880-3,895 (3.5 units) per ten patients. CONCLUSIONS: Transfusion incidence increases with DA initiation at lower Hb levels. Potential cost savings depend on the number of units transfused and cost items included. DA initiation according to guidelines can reduce transfusions and potentially reduce transfusion-associated costs.

Cost analysis: treatment of chemotherapy-induced anemia with erythropoiesis-stimulating agents in five European countries.

OBJECTIVE: Cost-analysis comparing darbepoetin-alfa (DARB), epoetin-alfa (EPO-A), and epoetin-beta (EPO-B) for treatment of chemotherapy-induced anemia in Belgium concluded that costs for DARB-treated patients were significantly lower than costs for EPO-A- or EPO-B-treated patients. The objective of the present study was to extend the Belgian analysis to Austria, France, Italy, Portugal, and Spain, estimating differences in costs between erythropoiesis-stimulating agents (ESAs) in each country. METHODS: Differences in epidemiology and treatment patterns between countries were adjusted using data from Eurostat, national cancer registries, IMS sales data, and reimbursement and treatment guidelines. Belgian unit costs were replaced with country-specific costs. Costs were analyzed using a mixed-effects model stratifying for propensity score quintiles. RESULTS: All populations were comparable to the Belgian population in terms of age, gender, ESA, and blood transfusions use. After adjusting for country-specific chemotherapy use and cancer incidence, total management costs per patient (Euro, 2010) were 19-26% (France, Spain) lower with DARB compared with EPO-A (p < 0.0001) and 20-36% (Portugal, Austria) compared with EPO-B (p < 0.01). Anemia-related costs with DARB were between 12% (Portugal; p = 0.0235) and 38% (Italy; p < 0.0001) lower compared with EPO-A (p < 0.01; all remaining countries), and between 13% (Austria; p = 0.064) and 19% (Portugal; p = 0.0028) lower compared with EPO-B (p < 0.05; all remaining countries except Italy; p = 0.0935). LIMITATIONS: Not all differences could be accounted for by a lack of country-specific data; however, the potential under- and over-estimation of costs should be similar for all three ESAs. CONCLUSIONS: These findings are in line with the Belgian analysis. In all countries, total and anemia-related costs were lowest in patients receiving DARB vs EPO-A or EPO-B. This study demonstrates the feasibility of adapting real-life country-specific data to other settings, adjusting for differences in patients' characteristics and treatment strategies. These findings should be valuable in healthcare decision-making in oncology patients treated in each of the countries studied.

Utilization and cost of health care services associated with primary malignant brain tumors in the United States.

OBJECTIVES: To evaluate the economic burden of primary malignant brain tumors in a commercially insured population in the United States, and to identify the primary drivers of health care resource use and cost. PATIENTS AND METHODS: A retrospective cohort analysis was performed using a 1998-2000 database containing inpatient, outpatient, and pharmacy claims for employees, their dependents, and early retirees of over 50 large US employers with wide geographic distribution. Patients were followed from first brain tumor diagnosis until death, termination of health benefits coverage, or study end. Controls without any cancer diagnosis were matched at a 3:1 ratio by demographic characteristics and length of follow-up. RESULTS: Patients with malignant brain tumors (n = 653) had significantly greater health service utilization and costs for hospitalizations, emergency room visits, outpatient office visits, laboratory tests, radiology services, and pharmacy-dispensed drugs (all P < 0.05) than did controls (n = 1959). Regression-adjusted mean monthly costs were $6364 for brain tumor patients, compared with $277 for controls (P < 0.0001). The primary cost driver was inpatient care ($4502 per month). Total costs during the study period were $49,242 for those with brain tumors and $2790 for controls (P < 0.0001). CONCLUSION: Patients with malignant brain tumors accrued health care costs that were 20 times greater than demographically matched control subjects without cancer. The costs for inpatient services were the primary drivers of total health resource use. Despite their low incidence, primary malignant brain tumors produce a substantial burden on the US health care system. There is a marked need for improved and new approaches to treatment to reduce the resource use and to offset health care costs associated with this disease.

Medical costs associated with non-Hodgkin's lymphoma in the United States during the first two years of treatment.

OBJECTIVES: To determine the direct costs of medical care associated with aggressive and indolent non-Hodgkin's lymphoma (NHL) in the United States; to show how costs for aggressive NHL change over time by examining costs related to initial, secondary and palliative treatment phases; and to evaluate the economic consequences of treatment failure in aggressive NHL. PATIENTS AND METHODS: A retrospective cohort analysis of 1999 - 2000 direct costs in newly diagnosed NHL patients and controls (subjects without any cancer) was conducted using the MarketScan medical and drug claims database of large employers across the United States. Treatment failure analysis was conducted for aggressive NHL patients, and was defined by the need for secondary treatment or palliative care after initial therapy. Cost of treatment failure was calculated as difference in regression-adjusted costs between patients with initial therapy only and patients experiencing initial treatment failure. RESULTS: Patients with aggressive (n = 356) and indolent (n = 698) NHL had significantly greater health service utilization and associated costs (all P < 05) than controls (n = 1068 for aggressive, n = 2094 for indolent). Mean monthly costs were 5871 dollars for aggressive NHL vs. 355 dollars for controls (P < 0001) and 3833 dollars for indolent NHL vs. 289 dollars for controls (P < 0001). The primary cost drivers were hospitalization (aggressive NHL = 44% of total costs, indolent NHL = 50%) and outpatient office visits (aggressive NHL = 39%, indolent NHL = 34%). For aggressive NHL, mean monthly initial treatment phase costs (10,970 dollars) and palliative care costs (9836 dollars) were higher than costs incurred during secondary phase (3302 dollars). The mean cost of treatment failure in aggressive NHL was 14,174 dollars per month, and 85,934 dollars over the study period. CONCLUSION: The treatment of NHL was associated with substantial health care costs. Patients with aggressive lymphomas tended to accrue higher costs, compared with those with indolent lymphomas. These costs varied over time, with the highest costs occurring during the initial treatment and palliative care phases. Treatment failure was the most expensive treatment pattern. New strategies to prevent or delay treatment failure in aggressive NHL could help reduce the economic burden of NHL.

Burden of pancreatic cancer and disease progression: economic analysis in the US.

OBJECTIVES: The few studies that have estimated the costs of pancreatic cancer were limited by small sample sizes, geography or patient age range. Using a large nationwide claims database, this study examines the cost of pancreatic cancer beginning with initial diagnosis and the additional costs when disease progresses. METHODS: A retrospective cohort study was conducted using a claims database of 3 million individuals covered by large US employers. The study population consisted of patients newly diagnosed with pancreatic cancer in 1999-2000 and a demographically matched control group. Utilization and costs were summarized as monthly means. Changes in cancer severity and treatment over time were used to approximate disease progression and its associated costs. RESULTS: The study included 412 pancreatic cancer patients and 1,236 controls. The mean follow-up time was 7.5 months. Regression-adjusted monthly costs attributable to pancreatic cancer were USD 7,279; over 60% resulted from hospitalizations. Patients with disease progression (over 50%) incurred an additional USD 15,143 per month compared to patients without disease progression. CONCLUSION: Compared to patients without cancer, the costs of pancreatic cancer patients were substantial, especially when patients experienced disease progression. New therapies that prevent or delay disease progression could potentially offset the costs to patients, providers and society.

The economic burden of lung cancer and the associated costs of treatment failure in the United States.

The economic burden of lung cancer was examined with a retrospective case-control cohort study on a database containing inpatient, outpatient and drug claims for employees, dependents and retirees of multiple large US employers with wide geographic distribution. Patients were followed for maximum of 2 years from first cancer diagnosis until death, health benefits dis-enrollment or study end (31 December 2000). Compared with controls (subjects without any cancer), patients with lung cancer (n = 2040) had greater health care service utilization and costs for hospitalization, emergency room visits, outpatient office visits, radiology procedures, laboratory procedures and pharmacy-dispensed drugs (all P < 0.05). Regression-adjusted mean monthly total costs were US dollar 6520 for patients versus US dollar 339 for controls (P < 0.0001), and overall costs across the study period (from diagnosis to death or maximum of 2 years) were US dollar 45,897 for patients and US dollar 2907 for controls (P < 0.0001). The main cost drivers were hospitalization (49.0% of costs) and outpatient office visits (35.2% of costs). Monthly initial treatment phase costs (US dollar 11,496 per patient) were higher than costs during the secondary treatment phase (US dollar 3733) or terminal care phase (US dollar 9399). Failure of initial treatment was associated with markedly increased costs. Compared with patients requiring only initial treatment, patients experiencing treatment failure accrued an additional US dollar 10,370 per month in initial treatment phase costs and US dollar 8779 more per month after starting the secondary and/or terminal care phase. Over the course of the study period, these patients had total costs of US dollar 120,650, compared with US dollar 45,953 for those receiving initial treatment only. Thus, the incremental costs associated with treatment failure were US dollar 19,149 per month and US dollar 74,697 across the study period. Other types of clinical and epidemiological analysis are needed to identify risks for treatment failure. The economic burden of lung cancer on the US health care system is significant and increased prevention, new therapies or adjuvant chemotherapy may reduce both resource use and healthcare costs. New strategies for lung cancer that reduce hospitalizations and/or prevent or delay treatment failure could offset some of the economic burden associated with the disease.

Estimating the cost of cancer: results on the basis of claims data analyses for cancer patients diagnosed with seven types of cancer during 1999 to 2000.

PURPOSE: Cancer accounts for 60.9 billion dollars in direct medical costs and 15.5 billion dollars for indirect morbidity costs. These estimates are derived primarily from national surveys or Federal databases. We derive estimates of the costs of cancer using administrative databases, which include claims and employment-related information on individuals insured by private or Medicare supplemental health plans. METHODS: A retrospective matched-cohort control analysis was performed using 1998 to 2000 databases with information on insurance claims, benefits, and health productivity for 3 million privately insured employees, their dependents, and early retirees. Study patients had new diagnoses of one of seven types of cancer (n = 12,709). Controls without cancer were matched at a 3:1 ratio by demographics. A variable follow-up length was used (maximum of 2 years). Direct costs included health care costs for patients and deductibles and copayments for caregivers. Indirect costs of work absence and short-term disability (STD) were calculated for a subgroup of cancer patients and caregivers. RESULTS: Mean monthly health care costs ranged from 2,187 dollars for prostate cancer to 7,616 dollars for pancreatic cancer, most often driven by hospitalization. Costs for controls were 329 dollars per month. Indirect morbidity costs to employees with cancer averaged 945 dollars, a result of a mean monthly loss of 2.0 workdays and 5.0 STD days. CONCLUSION: The economic burden of cancer is substantial. It is feasible to derive tumor-specific estimates of direct and indirect costs for large numbers of cancer patients using administrative databases. Policy makers charged with providing annual cost-of-cancer estimates should incorporate data obtained from a broad range of sources.
