Abstract
PURPOSE Patients with cancer are more likely to file for bankruptcy than the general population, but the impact of severe financial distress on health outcomes among patients with cancer is not known. METHODS We linked Western Washington SEER Cancer Registry records with federal bankruptcy records for the region. By using propensity score matching to account for differences in several demographic and clinical factors between patients who did and did not file for bankruptcy, we then fit Cox proportional hazards models to examine the relationship between bankruptcy filing and survival. RESULTS Between 1995 and 2009, 231,596 persons were diagnosed with cancer. Patients who filed for bankruptcy (n = 4,728) were more likely to be younger, female, and nonwhite, to have local- or regional- (v distant-) stage disease at diagnosis, and have received treatment. After propensity score matching, 3,841 patients remained in each group (bankruptcy v no bankruptcy). In the matched sample, mean age was 53.0 years, 54% were men, mean income was $49,000, and majorities were white (86%), married (60%), and urban (91%) and had local- or regional-stage disease at diagnosis (84%). Both groups received similar initial treatments. The adjusted hazard ratio for mortality among patients with cancer who filed for bankruptcy versus those who did not was 1.79 (95% CI, 1.64 to 1.96). Hazard ratios varied by cancer type: colorectal, prostate, and thyroid cancers had the highest hazard ratios. Excluding patients with distant-stage disease from the models did not have an effect on results. CONCLUSION Severe financial distress requiring bankruptcy protection after cancer diagnosis appears to be a risk factor for mortality. Further research is needed to understand the process by which extreme financial distress influences survival after cancer diagnosis and to find strategies that could mitigate this risk.

Abstract
PURPOSE Little is known about how referrals to different cancer specialists influence cancer care for non-small-cell lung cancer (NSCLC). Among Medicare enrollees, we identified factors of patients and their primary care physician that were associated with referrals to cancer specialists, and how the types of cancer specialists seen correlated with delivery of guideline-based therapies (GBTs). METHODS Data from patients with stages III and IV NSCLC included in the SEER-Medicare database were linked to their physicians in the American Medical Association Masterfile database. Using logistic regression, we (1) identified patient and physician factors that were associated with referrals to cancer specialists (medical oncologists, radiation oncologists, and surgeons); (2) identified the types of referral to cancer specialists that predicted greater likelihood of receiving GBT (per National Comprehensive Cancer Network guidelines). RESULTS A total of 28,977 patients with NSCLC diagnosed from January 1, 2000 to December 31, 2005 met eligibility criteria. Younger age, white race, higher income, and primary physician specialty other than family practice predicted higher likelihood of referrals to medical oncologists (P < .01 for all predictors). Seeing the three types of cancer specialists predicted higher likelihood of GBT (stage IIIA: odds ratio [OR] = 20.6; P < .001; IIIB: OR = 77.2; P < .001; and IV: OR = 1.2; P = .011), compared with seeing a medical oncologist only. Use of GBTs increased over the study period (42% to 48% from 2000 to 2005; P < .001). CONCLUSION Referrals to all types of cancer specialists increased the likelihood of treatment with standard therapies, particularly in stage III patients. However, racial and income disparities still prevent optimal referrals to cancer specialists.

Abstract
INTRODUCTION In this prospective study of localized prostate cancer patients and their partners, we analyzed how partner issues evolve over time, focusing on satisfaction with care, influence of cancer treatment, and its impact on relationship with patient, cancer worry, and personal activities. AIMS Our study aims were twofold: (i) to determine whether the impact of treatment on patients and partners moderate over time and (ii) if receiving surgery (i.e., radical prostatectomy) influences partner issues more than other treatments. METHODS Patients newly diagnosed with localized prostate cancer and their female partners were recruited from three states to complete surveys by mail at three time points over 12 months. MAIN OUTCOME MEASURES The four primary outcomes assessed in the partner analysis included satisfaction with treatment, cancer worry, and the influence of cancer and its treatment on their relationship (both general relationship and sexual relationship). RESULTS This analysis included 88 patient-partner pairs. At 6 months, partners reported that cancer had a negative impact on their sexual relationship (39%--somewhat negative and 12%--very negative). At 12 months, this proportion increased substantially (42%--somewhat negative and 29%--very negative). Partners were significantly more likely to report that their sexual relationship was worse when the patient reported having surgery (P = 0.0045, odds ratio = 9.8025, 95% confidence interval 2.076-46.296). A minority of partners reported significant negative impacts in other areas involving their personal activities (16% at 6 months and 25% at 12 months) or work life (6% at 6 months, which increased to 12% at 12 months). CONCLUSION From partners' perspectives, prostate cancer therapy has negative impact on sexual relationships and appears to worsen over time.

Abstract
BACKGROUND Breast cancer tumor markers are used by some clinicians to screen for disease recurrence risk. Since there is limited evidence of benefit, additional research may be warranted. AIM To assess the potential value of a randomized clinical trial of breast tumor marker testing in routine follow-up of high-risk, stage II-III breast cancer survivors. MATERIALS & METHODS We developed a decision-analytic model of tumor marker testing plus standard surveillance every 3-6 months for 5 years. The expected value of sample information was calculated using probabilistic simulations and was a function of: the probability of selecting the optimal monitoring strategy with current versus future information; the impact of choosing the nonoptimal strategy; and the size of the population affected. RESULTS The value of information for a randomized clinical trial involving 9000 women was US$214 million compared with a cost of US$30-60 million to conduct such a trial. The probability of making an alternate, nonoptimal decision and choosing testing versus no testing was 32% with current versus future information from the trial. The impact of a nonoptimal decision was US$2150 and size of population impacted over 10 years was 308,000. The value of improved information on overall survival was US$105 million, quality of life US$37 million and test performance US$71 million. CONCLUSION Conducting a randomized clinical trial of breast cancer tumor markers appears to offer a good societal return on investment. Retrospective analyses to assess test performance and evaluation of patient quality of life using tumor markers may also offer valuable areas of research. However, alternative investments may offer even better returns in investments and, as such, the trial concept deserves further study as part of an overall research-portfolio evaluation.

Abstract
Personalizing intravenous (IV) busulfan doses in children using therapeutic drug monitoring (TDM) is an integral component of hematopoietic cell transplant. The authors sought to characterize initial dosing and TDM of IV busulfan, along with factors associated with busulfan clearance, in 729 children who underwent busulfan TDM from December 2005 to December 2008. The initial IV busulfan dose in children weighing ≤12 kg ranged 4.8-fold, with only 19% prescribed the package insert dose of 1.1 mg/kg. In those children weighing >12 kg, the initial dose ranged 5.4-fold, and 79% were prescribed the package insert dose. The initial busulfan dose achieved the target exposure in only 24.3% of children. A wide range of busulfan exposures were targeted for children with the same disease (eg, 39 target busulfan exposures for the 264 children diagnosed with acute myeloid leukemia). Considerable heterogeneity exists regarding when TDM is conducted and the number of pharmacokinetic samples obtained. Busulfan clearance varied by age and dosing frequency but not by underlying disease. The authors- group is currently evaluating how using population pharmacokinetics to optimize initial busulfan dose and TDM (eg, limited sampling schedule in conjunction with maximum a posteriori Bayesian estimation) may affect clinical outcomes in children.

Abstract
BACKGROUND Identifying heart failure patients most likely to suffer poor outcomes is an essential part of delivering interventions to those most likely to benefit. We sought a comprehensive account of heart failure events and their cumulative economic burden by examining patient characteristics that predict increased cost or poor outcomes. METHODS We collected electronic medical data from members of a large HMO who had a heart failure diagnosis and an echocardiogram from 1999-2004, and followed them for one year. We examined the role of demographics, clinical and laboratory findings, comorbid disease and whether the heart failure was incident, as well as mortality. We used regression methods appropriate for censored cost data. RESULTS Of the 4,696 patients, 8% were incident. Several diseases were associated with significantly higher and economically relevant cost changes, including atrial fibrillation (15% higher), coronary artery disease (14% higher), chronic lung disease (29% higher), depression (36% higher), diabetes (38% higher) and hyperlipidemia (21% higher). Some factors were associated with costs in a counterintuitive fashion (i.e. lower costs in the presence of the factor) including age, ejection fraction and anemia. But anemia and ejection fraction were also associated with a higher death rate. CONCLUSIONS Close control of factors that are independently associated with higher cost or poor outcomes may be important for disease management. Analysis of costs in a disease like heart failure that has a high death rate underscores the need for economic methods to consider how mortality should best be considered in costing studies.

Abstract
AIM Meta-analyses have been used to evaluate associations between polymorphisms and colorectal cancer risk, but the quality of individual studies used to inform them may vary substantially. Our aim was to apply well-established quality-control criteria to individual association studies and then compare the results of meta-analyses that included or excluded studies that did not meet these criteria. METHOD We used meta-analyses of studies reporting a relationship between polymorphisms and colorectal cancer published between 1996 and 2008. Polymorphism-cancer associations were derived in separate meta-analyses including only those meeting the quality-control criteria. RESULTS Relative ORs varied substantially between the open and restricted group meta-analyses for all variants except MTHFR 677 CT. However, the associations were modest and the direction of relative risk did not change after applying criteria. Publication bias was detected for all associations, except the restricted set of studies for GSTP1 GG. CONCLUSION We observed variation in calculated relative risk and changes in tests for publication bias that were dependent on the inclusion criteria used for association studies of polymorphisms and colorectal cancer. Standardizing study inclusion criteria may reduce the variation in findings for meta-analyses of gene-association studies of common diseases such as colorectal cancer.

Abstract
e16524 Background: Despite not being recommended by clinical guidelines, the tumor markers carcinoembryonic antigen (CEA), cancer antigen (CA)15-3, and CA 27.29 are used by some clinicians to screen for increased risk of breast cancer recurrence. Although additional research may be warranted to evaluate the benefits and risks of breast cancer tumor marker tests, clinical trials would likely need to involve thousands of women and would take many years to complete. We conducted an analysis to assess the societal value of a prospective randomized clinical trial (RCT) for breast tumor marker testing in routine follow-up of high-risk, stage II-III breast cancer survivors Methods: We used value of information techniques to assess the benefits of reducing uncertainty of using breast cancer tumor markers. We developed a decision-analytic model of biomarker testing in addition to standard surveillance at follow-up appointments every 3-6 months for five years. Expected value of sample information (EVSI) was assessed over a range of trial sizes and assumptions. Results: The overall value of research for an RCT involving 9,000 women was $166 million (EVSI). The value of improved information characterizing the survival impact of tumor markers was $81 million, quality-of-life $38 million, and test performance $95 million. Conclusions: Our analysis indicates that substantial societal value may be gained by conducting a clinical trial evaluating the use of breast cancer tumor markers. The most important aspects of the trial in our analysis were information gained on survival improvements as well as quality-of-life parameters associated with testing and test sensitivity and specificity. Our analysis indicates that smaller randomized trials, as well as adding quality of life instruments to existing trials, retrospective, and observational trials can also generate valuable and relevant information.

Abstract
6007 Background: We identified the physicians initially involved in the management of stages III and IV NSCLC, and explored associations of patient and their initial physician factors with referrals to oncologists and subsequent receipt of guideline-based therapies (GBTs) endorsed by the National Comprehensive Cancer Network. Methods: Using a retrospective cohort design, we identified patients with a new diagnosis of stages III and IV NSCLC from 01/01/2000 to 12/31/2005 included in the Surveillance, Epidemiology, and End Results-Medicare database. After collecting patient sociodemographic, tumor, and treatment data, we linked Unique Physician Identifier Numbers (UPINs) from Medicare claims to the American Medical Association Masterfile database to identify the initial physicians and subsequent referrals to cancer specialists, defined as surgeons, radiation oncologists and oncologists. We used logistic regression to explore associations between: 1) patient and initial physician independent variables with referrals to oncologists; 2) referrals to different combinations of cancer specialists with receipt of stage-specific GBTs, adjusted for confounders. The follow-up period was 12 months or up to 12/31/2006. Results: For 28,977 patients, mean age was 75 years, 53% were male, 83% were white, 51% had stage IV, 37% initially saw an internal medicine doctor, 84% saw at least an oncologist, 31% saw all 3 types of cancer specialists, and 44% received GBTs. Younger age, white race, stage IV, higher income, lower co-morbidity index, initial physicians other than family practice doctors, and referral to pulmonologists were associated with higher likelihood of referral to oncologists (P<0.01 for all factors). Compared to those who saw only an oncologist, those who saw only a surgeon and/or a radiation specialist were less likely to receive GBTs (OR=0.3; 95%CI=0.3-0.4). Among patients who had no referrals or who saw specialties other than oncology, 14% received GBTs. Conclusions: Seeing an oncologist is a critical step in the standard treatment of advanced NSCLC. Yet, race, income, and the type of initial physician may constitute barriers of access to oncologists, which can result in substandard care.

Abstract
e14068 Background: The relative safety of newer drugs in older pts with mCRC is understudied. The objective of this analysis is to determine factors associated with AEs in a population-based sample of older mCRC pts treated in real-world clinical settings. Methods: Pts ≥ age 65 Dx with mCRC in 2004-2007 were identified from SEER-Medicare, and excluded if they were enrolled in a Medicare HMO or lacked Medicare parts A and B. Pts who received 1st line (1L) chemotherapy (CTx) within 3 mo of Dx were dichotomized as 1L CTx alone and 1L CTx + bevacizumab (BV). Preexisting conditions (PCs) identified from claims in the 12 mo prior to start of 1L CTx were grouped into 5 categories (cardiovascular (CV), cerebrovascular (CNS), gastrointestinal (GI), tissue integrity (TI), and pulmonary (Pulm)). Claims for any of these same conditions between start of 1L CTx and end of follow-up were identified as AEs. Crude AE incidence rates were determined. Logistic regression was used to examine factors associated with BV use. Factors associated with time to 1st AE were identified in a Cox model. Results: 4,514 pts (median age 77) met inclusion, of whom 1,139 (25%) received 1L CTx only and 669 (15%) received 1L CTx + BV. BV use was less likely among pts age ≥ 75 (OR 0.35, p<0.001), non-whites (OR 0.75, p=0.002), and women (OR 0.8, p=0.001). Bev use was as likely in pts with CV, Pulm, or CNS PCs, and more likely in pts with GI (OR 1.67, p <0.001) and TI (OR 2.75, p=0.001) PCs. In a Cox model of time to 1st AE with death as a competing risk, increased risk of AE was associated with age ≥ 75 (HR 1.13, p=0.02), CNS PC (HR 1.35, p=0.02), and CV PC (HR 1.13, p=0.05). Relative to 1L CTx alone, pts receiving 1L CTx + BV did not have a higher AE risk (HR 0.89, 95% CI 0.80-0.99). AE incidence was higher in pts receiving 1L CTx alone (without subsequent biologic) (185 events / 100,000 person-days (P-D) compared with pts receiving 1L CTx + BV (139 events / 100,000 P-D). Conclusions: In this cohort, pts who received 1L CTx + BV had neither increased AE incidence nor increased risk of 1st AE compared to pts who received 1L CTx alone. PCs were not associated with decreased BV use. These data suggests BV utilization may not increase AE risk among elderly mCRC pts tx in the community.

Abstract
BACKGROUND Several therapy options are available for symptomatic, treatment-naïve chronic lymphocytic leukemia (CLL). Many of these therapies have been compared against chlorambucil, but have not been directly compared against each other. There is currently no agreed upon standard therapeutic regimen for treatment-naïve CLL. METHODS We performed a systematic literature review to identify randomized controlled trials (RCTs) published prior to November 2011 of therapies for previously untreated CLL. We conducted a network meta-analysis using fixed and random effect statistical models to estimate differences between shape and scale parameters of progression-free survival (PFS) curves for each competing therapy. We used the parameter estimates and a Weibull distribution to project mean PFS for each therapy option. RESULTS Five RCTs were included in our comparison network. Overall, patients were younger (59-65 years), had good performance status based on the Eastern Cooperative Oncology Group scale (ECOG 0-1), and earlier stage disease (Rai 0-II or Binet A or B). The combination regimen fludarabine with cyclophosphamide and rituximab (FCR) was estimated to yield mean PFS of 76 months (95% CrI: 60, 91), FC 60 months (46, 73), fludarabine 38 months (27, 49), alemtuzumab 24 months (15, 32), and chlorambucil 23 months (15, 32). CONCLUSION Our results suggest that FCR has relatively higher potential of preventing disease progression in younger, healthier, treatment-naïve CLL patients and should be considered an optimal initial treatment strategy for this patient population. However, because estimates are based on model simulation, additional studies of FCR are necessary to clinically validate its therapeutic potential.

Abstract
OBJECTIVES We sought to determine whether health insurance coverage of colorectal cancer (CRC) screening varied based on risk. BACKGROUND Population-wide screening guidelines for cancer often incorporate risk information, with modified screening recommendations for those at higher risk due to family history or other factors. METHODS In a nationwide Internet- and mail-based survey of health insurance plan medical directors, respondents were asked about their organization's policies towards coverage of CRC screening for persons at average and higher risk of CRC. Additional questions asked about whether the insurer had a definition of increased risk, and coverage of genetic testing for familial CRC syndromes. RESULTS Survey invitations were sent to 1158 medical directors; 133 (11%) completed the survey. All plans covered screening for average and high-risk persons. The onset of screening was earlier and intervals were more frequent for higher risk compared to average risk persons, with most respondents stating coverage was determined by "physician discretion." While 75% had a definition of high risk, only 55% covered genetic testing. CONCLUSIONS Most insurers offer enhanced coverage of CRC screening, most commonly following the discretion of the physician. Whether this coverage results in earlier, more frequent, or more complete screening of higher risk persons remains uncertain.

Abstract
BACKGROUND AND OBJECTIVES Most patients with myelodysplastic syndrome (MDS) require blood product support to manage the severe anaemias, which frequently accompany MDS. Our objective was to show the feasibility of linking the Surveillance, Epidemiology and End Results (SEER) database with records from Puget Sound Blood Center (PSBC) to characterize blood product use over time in successive cohorts of patients with MDS. MATERIALS AND METHODS We identified patients with MDS in the SEER registry. The cohort was then linked to PSBC records to discern blood product use. RESULTS Included in the analysis were 783 patients with MDS entered in the SEER database from 2001 to 2007 for whom data were also available in the PSBC database. Among patients with MDS who received transfusions, 97% received packed red blood cells; 52% received platelets. The proportion of patients with MDS receiving blood products declined from 2001 to 2007. CONCLUSION These data show a recent decline in blood product use for patients with MDS. Future studies are needed to further evaluate the reasons for this finding, specifically exploring the impact of newer medications on blood product use in patients with MDS.

Abstract
OBJECTIVE • To evaluate the degree to which the partners of prostate cancer patients participate in the shared decision-making process with the patients' providers during the time between diagnosis and initiating treatment. PATIENTS AND METHODS • We recruited patients with newly diagnosed local-stage prostate cancer and their partners to complete take-home surveys after biopsy but before initiating treatment at urology practices in three states. • We asked partners to describe their roles in the decision-making process, including participation in clinic visits, and perceptions of encouragement from providers to participate in the treatment decision-making process. We also asked partners to rate their satisfaction with the patients' providers. RESULTS • Family members of 80% of newly diagnosed patients agreed to participate; most (93%) were partners (i.e. spouses or significant others). Most partners (93%) had direct contact with the patients' physicians. • Among the partners who had contact with providers, most (67%) were very satisfied with the patients' providers and 80% indicated that the doctor encouraged them to participate in the treatment decision. Overall, 91% of partners reported very frequent discussions with their loved one about the pending treatment decision, and 69% reported that their role was to help the patient make a decision. • In multivariate models, provider encouragement of partner participation was associated with higher partner satisfaction (odds ratio 3.4, 95% CI 1.4-8.4) and an increased likelihood of partners reporting very frequent discussions with their loved one (odds ratio 6.1, 95% CI 1.3-27.7). CONCLUSIONS • Partners often attended clinic visits and were very involved in discussions about treatment options with both loved ones and providers. • Provider encouragement of participation by partners greatly facilitates shared decision-making between patients and partners.

Abstract
PURPOSE Distance to provider might be an important barrier to timely diagnosis and treatment for cancer patients who qualify for Medicaid coverage. Whether driving time or driving distance is a better indicator of travel burden is also of interest. METHODS Driving distances and times from patient residence to primary care provider were calculated for 3,917 breast, colorectal (CRC) and lung cancer Medicaid patients in Washington State from 1997 to 2003 using MapQuest.com. We fitted regression models of stage at diagnosis and time-to-treatment (number of days between diagnosis and surgery) to test the hypothesis that travel burden is associated with timely diagnosis and treatment of cancer. FINDINGS Later stage at diagnosis for breast cancer Medicaid patients is associated with travel burden (OR = 1.488 per 100 driving miles, P= .037 and OR = 1.270 per driving hour, P= .016). Time-to-treatment after diagnosis of CRC is also associated with travel burden (14.57 days per 100 driving miles, P= .002 and 5.86 days per driving hour, P= .018). CONCLUSIONS Although travel burden is associated with timely diagnosis and treatment for some types of cancer, we did not find evidence that driving time was, in general, better at predicting timeliness of cancer diagnosis and treatment than driving distance. More intensive efforts at early detection of breast cancer and early treatment of CRC for Medicaid patients who live in remote areas may be needed.

Abstract
OBJECTIVES We examined health care use in conjunction with primary prophylaxis use of colony stimulating factors (CSF) during patients' initial course of chemotherapy. METHODS This retrospective cohort study identified adults aged 25 years and older with a diagnosis of breast, colorectal, or nonsmall cell lung cancer between 2002 and 2005 from the Western Washington Surveillance Epidemiology and End Results Puget Sound registry. We linked these records to health insurance claims from four payers representing 75% of those insured in the state. Claims records were used to determine chemotherapy regimen type, CSF use, febrile neutropenia occurrences, and supportive care. Chemotherapy regimens were categorized as conferring high, intermediate, or low risk of myelosuppression according to the National Comprehensive Cancer Network guidelines. CSF use was described as primary prophylaxis, other, or none. Antibiotics and antifungal and antiviral agents per National Comprehensive Cancer Network guidelines for supportive care for cancer infection were categorized using Healthcare Common Procedure Coding System and National Drug Code assignments. RESULTS Use of CSF as primary prophylaxis is not significantly associated with a reduction in antibiotic use or inpatient or outpatient visits. Primary prophylactic CSF use was associated with less use of antiviral drugs. CONCLUSIONS CSF use is not associated with a reduction in health care use, with the exception of antiviral drug use. Given the expense associated with CSF use, pragmatic trials and additional research are needed to further assess the affects of CSF on health care use.

Abstract
BACKGROUND Patients who misuse alcohol are at increased risk for surgical complications. Four weeks of preoperative abstinence decreases the risk of complications, but practical approaches for early preoperative identification of alcohol misuse are needed. OBJECTIVE To evaluate whether results of alcohol screening with the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire-up to a year before surgery-were associated with the risk of postoperative complications. DESIGN This is a cohort study. SETTING AND PARTICIPANTS Male Veterans Affairs (VA) patients were eligible if they had major noncardiac surgery assessed by the VA's Surgical Quality Improvement Program (VASQIP) in fiscal years 2004-2006, and completed the AUDIT-C alcohol screening questionnaire (0-12 points) on a mailed survey within 1 year before surgery. MAIN OUTCOME MEASURE One or more postoperative complication(s) within 30 days of surgery based on VASQIP nurse medical record reviews. RESULTS Among 9,176 eligible men, 16.3% screened positive for alcohol misuse with AUDIT-C scores ≥ 5, and 7.8% had postoperative complications. Patients with AUDIT-C scores ≥ 5 were at significantly increased risk for postoperative complications, compared to patients who drank less. In analyses adjusted for age, smoking, and days from screening to surgery, the estimated prevalence of postoperative complications increased from 5.6% (95% CI 4.8-6.6%) in patients with AUDIT-C scores 1-4, to 7.9% (6.3-9.7%) in patients with AUDIT-Cs 5-8, 9.7% (6.6-14.1%) in patients with AUDIT-Cs 9-10 and 14.0% (8.9-21.3%) in patients with AUDIT-Cs 11-12. In fully-adjusted analyses that included preoperative covariates potentially in the causal pathway between alcohol misuse and complications, the estimated prevalence of postoperative complications increased significantly from 4.8% (4.1-5.7%) in patients with AUDIT-C scores 1-4, to 6.9% (5.5-8.7%) in patients with AUDIT-Cs 5-8 and 7.5% (5.0-11.3%) among those with AUDIT-Cs 9-10. CONCLUSIONS AUDIT-C scores of 5 or more up to a year before surgery were associated with increased postoperative complications.

Abstract
This study projects prosthetic- and assistive-device costs for veterans with limb loss from Vietnam and injured servicemembers returning from Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) to inform the Department of Veterans Affairs (VA) for these veterans' future care. The 2005 Medicare prosthetic device component prices were applied to current prosthetic and assistive-device use obtained from a national survey of 581 veterans and servicemembers with major traumatic amputations. Projections were made for 5-year, 10-year, 20-year, and lifetime costs based on eight Markov models. Average 5-year projected costs for prosthetic and assistive-device replacement for the Vietnam group are lower than for the OIF/OEF cohort due in part to use of fewer and less technologically advanced prosthetic devices and higher frequency of prosthetic abandonment. By limb-loss level, for the Vietnam group and OIF/OEF cohort, 5-year projected unilateral upper limb average costs are $31,129 and $117,440, unilateral lower limb costs are $82,251 and $228,665, and multiple limb costs are $130,890 and $453,696, respectively. These figures provide the VA with a funding estimate for technologically advanced prosthetic and assistive devices within the framework of ongoing rehabilitation for veterans with traumatic limb loss from the Vietnam and OIF/OEF conflicts.
