Abstract
OBJECTIVES Health coaches can help patients gain knowledge, skills, and confidence to manage their chronic conditions. Coaches may be particularly valuable in resource-poor settings, but they are not typically reimbursed by insurance, raising questions about their budgetary impact. STUDY DESIGN The Health Coaching in Primary Care (HCPC) study was a randomized controlled trial that showed health coaches were effective at helping low-income patients improve control of their type 2 diabetes, hypertension, and/or hyperlipidemia at 12 months compared with usual care. METHODS We estimated the cost of employing 3 health coaches and mapped these costs to participants. We tested whether the added costs of the coaches were offset by any savings in healthcare utilization within 1 year. Healthcare utilization data were obtained from 5 sources. Multivariate models assessed differences in costs at 1 year controlling for baseline characteristics. RESULTS Coaches worked an average of 9 hours with each participant over the length of the study. On average, the health coach intervention cost $483 per participant per year. The average healthcare costs for the coaching group was $3207 compared with $3276 for the control group (P = .90). There was no evidence that the coaching intervention saved money at 1 year. CONCLUSIONS Health coaches have been shown to improve clinical outcomes related to chronic disease management. We found that employing health coaches adds an additional cost of $483 per patient per year. The data do not suggest that health coaches pay for themselves by reducing healthcare utilization in the first year.

Abstract
OBJECTIVE To compare risk scores computed by DxCG (Verisk) and Centers for Medicare and Medicaid Services (CMS) V21. RESEARCH DESIGN Analysis of administrative data from the Department of Veterans Affairs (VA) for fiscal years 2010 and 2011. STUDY DESIGN We regressed total annual VA costs on predicted risk scores. Model fit was judged by R-squared, root mean squared error, mean absolute error, and Hosmer-Lemeshow goodness-of-fit tests. Recalibrated models were tested using split samples with pharmacy data. DATA COLLECTION We created six analytical files: a random sample (n = 2 million), high cost users (n = 261,487), users over age 75 (n = 644,524), mental health and substance use users (n = 830,832), multimorbid users (n = 817,951), and low-risk users (n = 78,032). PRINCIPAL FINDINGS The DxCG Medicaid with pharmacy risk score yielded substantial gains in fit over the V21 model. Recalibrating the V21 model using VA pharmacy data-generated risk scores with similar fit statistics to the DxCG risk scores. CONCLUSIONS Although the CMS V21 and DxCG prospective risk scores were similar, the DxCG model with pharmacy data offered improved fit over V21. However, health care systems, such as the VA, can recalibrate the V21 model with additional variables to develop a tailored risk score that compares favorably to the DxCG models.

Abstract
BACKGROUND Unlike Medicare, the Veterans Health Administration (VA) health care system does not require veterans with cancer to make the "terrible choice" between receipt of hospice services or disease-modifying chemotherapy/radiation therapy. For this report, the authors characterized the VA's provision of concurrent care, defined as days in the last 6 months of life during which veterans simultaneously received hospice services and chemotherapy or radiation therapy. METHODS This retrospective cohort study included veteran decedents with cancer during 2006 through 2012 who were identified from claims with cancer diagnoses. Hospice and cancer treatment were identified using VA and Medicare administrative data. Descriptive statistics were used to characterize the changes in concurrent care, hospice, palliative care, and chemotherapy or radiation treatment. RESULTS The proportion of veterans receiving chemotherapy or radiation therapy remained stable at approximately 45%, whereas the proportion of veterans who received hospice increased from 55% to 68%. The receipt of concurrent care also increased during this time from 16.2% to 24.5%. The median time between hospice initiation and death remained stable at around 21 days. Among veterans who received chemotherapy or radiation therapy in their last 6 months of life, the median time between treatment termination and death ranged from 35 to 40 days. There was considerable variation between VA medical centers in the use of concurrent care (interquartile range, 16%-34% in 2012). CONCLUSIONS Concurrent receipt of hospice and chemotherapy or radiation therapy increased among veterans dying from cancer without reductions in the receipt of cancer therapy. This approach reflects the expansion of hospice services in the VA with VA policy allowing the concurrent receipt of hospice and antineoplastic therapies.

Abstract
BACKGROUND Observational studies of Alcoholics Anonymous' (AA) effectiveness are vulnerable to self-selection bias because individuals choose whether or not to attend AA. The present study, therefore, employed an innovative statistical technique to derive a selection bias-free estimate of AA's impact. METHODS Six data sets from 5 National Institutes of Health-funded randomized trials (1 with 2 independent parallel arms) of AA facilitation interventions were analyzed using instrumental variables models. Alcohol-dependent individuals in one of the data sets (n = 774) were analyzed separately from the rest of sample (n = 1,582 individuals pooled from 5 data sets) because of heterogeneity in sample parameters. Randomization itself was used as the instrumental variable. RESULTS Randomization was a good instrument in both samples, effectively predicting increased AA attendance that could not be attributed to self-selection. In 5 of the 6 data sets, which were pooled for analysis, increased AA attendance that was attributable to randomization (i.e., free of self-selection bias) was effective at increasing days of abstinence at 3-month (B = 0.38, p = 0.001) and 15-month (B = 0.42, p = 0.04) follow-up. However, in the remaining data set, in which preexisting AA attendance was much higher, further increases in AA involvement caused by the randomly assigned facilitation intervention did not affect drinking outcome. CONCLUSIONS For most individuals seeking help for alcohol problems, increasing AA attendance leads to short- and long-term decreases in alcohol consumption that cannot be attributed to self-selection. However, for populations with high preexisting AA involvement, further increases in AA attendance may have little impact.

Abstract
OBJECTIVES To investigate the relationship between multimorbidity and healthcare utilisation patterns among the highest cost patients in a large, integrated healthcare system. DESIGN In this retrospective cross-sectional study of all patients in the U.S. Veterans Affairs (VA) Health Care System, we aggregated costs of individuals' outpatient and inpatient care, pharmacy services and VA-sponsored contract care received in 2010. We assessed chronic condition prevalence, multimorbidity as measured by comorbidity count, and multisystem multimorbidity (number of body systems affected by chronic conditions) among the 5% highest cost patients. Using multivariate regression, we examined the association between multimorbidity and healthcare utilisation and costs, adjusting for age, sex, race/ethnicity, marital status, homelessness and health insurance status. SETTING USA VA Health Care System. PARTICIPANTS 5.2 million VA patients. MEASURES Annual total costs; absolute and share of costs generated through outpatient, inpatient, pharmacy and VA-sponsored contract care; number of visits to primary, specialty and mental healthcare; number of emergency department visits and hospitalisations. RESULTS The 5% highest cost patients (n=261,699) accounted for 47% of total VA costs. Approximately two-thirds of these patients had chronic conditions affecting ≥3 body systems. Patients with cancer and schizophrenia were less likely to have documented comorbid conditions than other high-cost patients. Multimorbidity was generally associated with greater outpatient and inpatient utilisation. However, increased multisystem multimorbidity was associated with a higher outpatient share of total costs (1.6 percentage points per affected body system, p<0.01) but a lower inpatient share of total costs (-0.6 percentage points per affected body system, p<0.01). CONCLUSIONS Multisystem multimorbidity is common among high-cost VA patients. While some patients might benefit from disease-specific programmes, for most patients with multimorbidity there is a need for interventions that coordinate and maximise efficiency of outpatient services across multiple conditions.

Abstract
BACKGROUND The Department of Veterans Affairs (VA) mandates disclosure of large-scale adverse events to patients, even if risk of harm is not clearly present. Concerns about past disclosures warranted further examination of the impact of this policy. OBJECTIVE Through a collaborative partnership between VA leaders, policymakers, researchers and stakeholders, the objective was to empirically identify critical aspects of disclosure processes as a first step towards improving future disclosures. DESIGN Semi-structured interviews were conducted with participants at nine VA facilities where recent disclosures took place. PARTICIPANTS Ninety-seven stakeholders participated in the interviews: 38 employees, 28 leaders (from facilities, regions and national offices), 27 Veteran patients and family members, and four congressional staff members. APPROACH Facility and regional leaders were interviewed by telephone, followed by a two-day site visit where employees, patients and family members were interviewed face-to-face. National leaders and congressional staff also completed telephone interviews. Interviews were analyzed using rapid qualitative assessment processes. Themes were mapped to the stages of the Crisis and Emergency Risk Communication model: pre-crisis, initial event, maintenance, resolution and evaluation. KEY RESULTS Many areas for improvement during disclosure were identified, such as preparing facilities better (pre-crisis), creating rapid communications, modifying disclosure language, addressing perceptions of harm, reducing complexity, and seeking assistance from others (initial event), managing communication with other stakeholders (maintenance), minimizing effects on staff and improving trust (resolution), and addressing facilities' needs (evaluation). CONCLUSIONS Through the partnership, five recommendations to improve disclosures during each stage of communication have been widely disseminated throughout the VA using non-academic strategies. Some improvements have been made; other recommendations will be addressed through implementation of a large-scale adverse event disclosure toolkit. These toolkit strategies will enable leaders to provide timely and transparent information to patients and families, while reducing the burden on employees and the healthcare system during these events.

Abstract
BACKGROUND New-onset postoperative atrial fibrillation (POAF) after coronary artery bypass graft surgery (CABG) is associated with worse in-hospital morbidity and mortality, extended hospital stays, and higher costs. Beyond the initial hospital discharge, the cost and outcomes of POAF have not been well studied. METHODS For CABG patients with and without new-onset POAF, a retrospective propensity-matched, multivariable regression analysis was performed to compare 1-year outcomes (including health-related quality of life [HRQoL] scores and mortality rates) and costs (standardized to 2010 dollars). Regression models controlled for site and patient factors, with propensity matching used to adjust for differences in POAF versus no-POAF patients' risk profiles. RESULTS Using the existing CABG trial database, 2,096 patient records were analyzed, including POAF patients (n = 549) versus no-POAF patients (n = 1,547). For the index CABG hospitalization, POAF patients had longer postoperative length of stay (+3.9 days) and higher discharge costs (+$13,993) than no-POAF patients. At 1 year, POAF patients had more than twice the adjusted odds of dying (p < 0.01), with higher 1-year total cumulative costs. This 1-year cost difference (+$15,593) was largely attributable to hospital-based costs during the index surgery hospitalization. There was no difference in 1-year HRQoL scores (or HRQoL score changes) between POAF patients and no-POAF patients. CONCLUSIONS Compared with no-POAF patients, POAF patients had higher discharge and 1-year costs along with higher 1-year mortality rates, but no differences were observed in 1-year HRQoL scores. Additional research appears warranted to improve the longer-term survival rates for POAF CABG patients, targeting future POAF-specific postdischarge interventions.

Abstract
BACKGROUND PET scanning has been shown in randomized trials to reduce the frequency of surgery without cure among patients with potentially resectable non-small cell lung cancer (NSCLC). We examined whether more frequent use of PET scanning at the facility level improves survival among patients with NSCLC in real-world practice. METHODS In this prospective cohort study of 622 US veterans with newly diagnosed NSCLC, we compared groups defined by the frequency of PET scan use measured at the facility level and categorized as low (<25%), medium (25%-60%), or high (>60%). RESULTS The median age of the sample was 69 years. Ninety-eight percent were men, 36% were Hispanic or nonwhite, and 54% had moderate or severe comorbidities. At low-, medium-, and high-use facilities, PET scan was performed in 13%, 40%, and 72% of patients, respectively (P<.0001). Baseline characteristics were similar across groups, including clinical stage based on CT scanning. More frequent use of PET scanning was associated with more frequent invasive staging (P<.001) and nonsignificant improvements in downstaging (P=.13) and surgery without cure (P=.12). After a median of 352 days of follow-up, 22% of the sample was still alive, including 22% at low- and medium-use facilities and 20% at high-use facilities. After adjustment and compared with patients at low-use facilities, the hazard of death was greater for patients at high-use facilities (adjusted hazard ratio [HR], 1.35; 95% CI, 1.05-1.74) but not different for patients at medium-use facilities (adjusted HR, 1.14; 95% CI, 0.88-1.46). CONCLUSIONS In this study of veterans with NSCLC, markedly greater use of PET scanning at the facility level was associated with more frequent use of invasive staging and possible improvements in downstaging and surgery without cure, but greater use of PET scanning was not associated with better survival.

Abstract
We sought to analyze utilization and survival outcomes of cytoreductive nephrectomy (CN) in patients with metastatic renal cell carcinoma (RCC) before and after introduction of targeted therapy. We identified patients with metastatic RCC between 1993 and 2010 in the SEER registry and examined temporal trends in utilization. We performed a joinpoint regression to determine when changes in utilization of CN occurred. We fitted multivariable proportional hazard models in full and propensity score-matched cohorts. We performed a difference-in-difference analysis to compare survival outcomes before and after introduction of targeted therapy. The proportion of patients undergoing CN increased from 1993 to 2004, from 29% to 39%. We identified a primary joinpoint of 2004, just prior to the introduction of targeted therapy. Beginning in 2005, there was a modest decrease in utilization of CN. CN was associated with a lower adjusted relative hazard (0.41, 95% confidence interval 0.34–0.43). Median survival among patients receiving CN increased in the targeted therapy era (19 vs. 13 months), while median survival among patients not receiving CN increased only slightly (4 vs. 3 months). Difference-in-difference analysis showed a significant decrease in hazard of death among patients who received CN in the targeted therapy era. Despite decreased utilization in the targeted therapy era, CN remains associated with improved survival. Prospective randomized trials are needed to confirm the benefit of CN among patients with metastatic RCC treated with novel targeted therapies.

Abstract
IMPORTANCE To date, no study has defined the consequences of radial artery harvest based on a large number of patients in a prospective randomized trial. OBJECTIVE To compare pain at the harvest site and functional changes associated with harvesting the radial artery vs saphenous vein for coronary artery bypass grafting. DESIGN, SETTING, AND PARTICIPANTS This study compares the consequences of radial artery harvest with saphenous vein harvest in patients undergoing elective coronary artery bypass grafting procedures in Veterans Affairs hospitals. MAIN OUTCOMES AND MEASURES Eleven hospitals screened 6148 patients, of whom 751 were included in this trial. We analyzed 2 variables: pain at the harvest site as measured on a scale of 0 to 100 (least to most painful) and hand performance testing. Patients included in this analysis had radial artery only (n = 80) or saphenous vein only (n = 337) harvest. Pain score, grip strength, and dexterity were measured before surgery and at 3 and 12 months after surgery. We adjusted for pain scores of the nonharvested extremity, age, whether the patient underwent endoscopic vein harvesting, and comorbid health conditions (smoking history, type 2 diabetes mellitus, hypertension, and heart failure). RESULTS There was a significant difference in change of pain score at 3 months from the preoperative baseline between radial artery and saphenous vein groups after adjusting for covariates (P < .001) but not at 12 months (P = .07). No significant changes occurred in grip strength or dexterity from preoperative baseline to 3 and 12 months after surgery (P > .05). CONCLUSIONS AND RELEVANCE The radial artery group reported significantly more pain than the saphenous vein group 3 months after surgery; however, similar levels of pain were observed in both groups at 12 months after surgery. Grip strength and manual dexterity were not changed by radial artery harvesting at 3 and 12 months.

Abstract
OBJECTIVE To examine the patient, tumor, and temporal factors associated with receipt of renal mass biopsy (RMB) in a contemporary nationally representative sample. METHODS We queried the Surveillance, Epidemiology, and End Results-Medicare data set for incident cases of renal cell carcinoma diagnosed between 1992 and 2007. We tested for associations among receipt of RMB and patient and tumor characteristics, type of therapy, and procedure type. Temporal trends in receipt of RMB were characterized over the study period. RESULTS Approximately 1 in 5 (20.7%) patients diagnosed with renal cell carcinoma (n = 24,702) underwent RMB before instituting therapy. There was a steady and modest increase in RMB utilization, with the highest utilization (30%) occurring in the final study year. Of patients who underwent radical (n = 15,666) or partial (n = 2211) nephrectomy, 17% and 20%, respectively, underwent RMB in advance of surgery. Sixty-five percent of patients who underwent ablation (n = 314) underwent RMB before or in conjunction with the procedure. Roughly half of patients (50.4%) treated with systemic therapy alone underwent RMB. Factors independently associated with use of RMB included younger age, black race, Hispanic ethnicity, tumor size <7 cm, and metastatic disease at presentation. CONCLUSION At present, most patients who eventually undergo radical or partial nephrectomy do not undergo RMB, whereas most patients who eventually undergo ablation or systemic therapy do. The optimal use of RMB in the evaluation of kidney tumors has yet to be determined.

Abstract
OBJECTIVE To estimate the cost-effectiveness of a supported employment (SE) intervention that had been previously found effective in veterans with spinal cord injuries (SCIs). DESIGN Cost-effectiveness analysis, using cost and quality-of-life data gathered in a trial of SE for veterans with SCI. SETTING SCI centers in the Veterans Health Administration. PARTICIPANTS Subjects (N=157) who completed a study of SE in 6 SCI centers. Subjects were randomly assigned to the intervention of SE (n=81) or treatment as usual (n=76). INTERVENTION A vocational rehabilitation program of SE for veterans with SCI. MAIN OUTCOME MEASURES Costs and quality-adjusted life years, which were estimated from the Veterans Rand 36-Item Health Survey, extrapolated to Veterans Rand 6 Dimension utilities. RESULTS Average cost for the SE intervention was $1821. In 1 year of follow-up, estimated total costs, including health care utilization and travel expenses, and average quality-adjusted life years were not significantly different between groups, suggesting the Spinal Cord Injury Vocational Integration Program intervention was not cost-effective compared with usual care. CONCLUSIONS An intensive program of SE for veterans with SCI, which is more effective in achieving competitive employment, is not cost-effective after 1 year of follow-up. Longer follow-up and a larger study sample will be necessary to determine whether SE yields benefits and is cost-effective in the long run for a population with SCI.

Abstract
The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health convened a working group in June 2011 to examine alternative institutional review board (IRB) models. The working group was held in response to proposed changes in the regulations for government-supported research and the proliferation of multicenter clinical trials where multiple individual reviews may be inefficient. Group members included experts in heart, lung, and blood research, research oversight, bioethics, health economics, regulations, and information technology (IT). The group discussed alternative IRB models, ethical concerns, metrics for evaluating IRBs, IT needs, and economic considerations. Participants noted research gaps in IRB best practices and in metrics. The group arrived at recommendations for process changes, such as defining specific IRB performance requirements in funding announcements, requiring funded researchers to use more efficient alternative IRB models, and developing IT systems to facilitate information sharing and collaboration among IRBs. Despite the success of the National Cancer Institute's central IRB (CIRB), the working group, concerned about the creation costs and unknown cost-efficiency of a new CIRB, and about the risk of shifting the burden of dealing with multiple IRBs from sponsors to research institutions, did not recommend the creation of an NHLBI-funded CIRB.

Abstract
BACKGROUND Improving a patient's ability to self-monitor and manage changes in chronic obstructive pulmonary disease (COPD) symptoms may improve outcomes. OBJECTIVE To determine the efficacy of a comprehensive care management program (CCMP) in reducing the risk for COPD hospitalization. DESIGN A randomized, controlled trial comparing CCMP with guideline-based usual care. (ClinicalTrials.gov registration number: NCT00395083) SETTING: 20 Veterans Affairs hospital-based outpatient clinics. PARTICIPANTS Patients hospitalized for COPD in the past year. INTERVENTION The CCMP included COPD education during 4 individual sessions and 1 group session, an action plan for identification and treatment of exacerbations, and scheduled proactive telephone calls for case management. Patients in both the intervention and usual care groups received a COPD informational booklet; their primary care providers received a copy of COPD guidelines and were advised to manage their patients according to these guidelines. Patients were randomly assigned, stratifying by site based on random, permuted blocks of variable size. MEASUREMENTS The primary outcome was time to first COPD hospitalization. Staff blinded to study group performed telephone-based assessment of COPD exacerbations and hospitalizations, and all hospitalizations were blindly adjudicated. Secondary outcomes included non-COPD health care use, all-cause mortality, health-related quality of life, patient satisfaction, disease knowledge, and self-efficacy. RESULTS Of the eligible patients, 209 were randomly assigned to the intervention group and 217 to the usual care group. Citing serious safety concerns, the data monitoring committee terminated the intervention before the trial's planned completion after 426 (44%) of the planned total of 960 patients were enrolled. Mean follow-up was 250 days. When the study was stopped, the 1-year cumulative incidence of COPD-related hospitalization was 27% in the intervention group and 24% in the usual care group (hazard ratio, 1.13 [95% CI, 0.70 to 1.80]; P= 0.62). There were 28 deaths from all causes in the intervention group versus 10 in the usual care group (hazard ratio, 3.00 [CI, 1.46 to 6.17]; P= 0.003). Cause could be assigned in 27 (71%) deaths. Deaths due to COPD accounted for the largest difference: 10 in the intervention group versus 3 in the usual care group (hazard ratio, 3.60 [CI, 0.99 to 13.08]; P= 0.053). LIMITATIONS Available data could not fully explain the excess mortality in the intervention group. Ability to assess the quality of the educational sessions provided by the case managers was limited. CONCLUSION A CCMP in patients with severe COPD had not decreased COPD-related hospitalizations when the trial was stopped prematurely. The CCMP was associated with unanticipated excess mortality, results that differ markedly from similar previous trials. A data monitoring committee should be considered in the design of clinical trials involving behavioral interventions.

Abstract
BACKGROUND Electronic personal health record (PHR) systems are proliferating but largely have not realized their potential for enhancing communication among patients and their network of care providers. OBJECTIVE To explore preferences about sharing electronic health information among users of the U.S. Department of Veterans Affairs (VA) PHR system, My HealtheVet. DESIGN Web-based survey of a convenience sample. SETTING My HealtheVet Web site from 7 July through 4 October 2010. PARTICIPANTS 18 471 users of My HealtheVet. MEASUREMENTS Interest in shared PHR access and preferences about who would receive access, the information that would be shared, and the activities that users would delegate. RESULTS Survey respondents were predominantly men (92%) and aged 50 to 64 years (51%) or 65 years or older (39%); approximately 39% reported poor or fair health status. Almost 4 of 5 respondents (79%) were interested in sharing access to their PHR with someone outside of their health system (62% with a spouse or partner, 23% with a child, 15% with another family member, and 25% with a non-VA health care provider). Among those who selected a family member other than a spouse or partner, 47% lived apart from the specified person. Preferences about degree of access varied on the basis of the type of information being shared, the type of activity being performed, and the respondent's relationship with the selected person. LIMITATIONS The survey completion rate was 40.8%. Results might not be generalizable to all My HealtheVet users. CONCLUSION In a large survey of PHR users in the VA system, most respondents were interested in sharing access to their electronic health information with caregivers and non-VA providers. Existing and evolving PHR systems should explore secure mechanisms for shared PHR access to improve information exchange among patients and the multiple persons involved in their health care.

Abstract
The change in prevalence and total Veterans Affairs (VA) spending were estimated for 16 chronic condition categories between 2000 and 2008. The drivers of changes in spending also were examined. Chronic conditions were identified through diagnoses in encounter records, and treatment costs per patient were estimated using VA cost data and regression models. The estimated differences in total VA spending between 2000 and 2008 and the contributions of population increase, differences in prevalence, and differences in treatment costs were evaluated. Most of the spending increases during the study period were driven by the increase in the VA patient population from 3.3 million in 2000 to 4.9 million in 2008. Spending on renal failure increased the most, by more than $1.5 billion, primarily because of higher prevalence. Higher treatment costs did not contribute much to higher spending; lower costs per patient for several conditions may have helped to slow spending for diabetes, chronic obstructive pulmonary disease, heart conditions, renal failure, dementia, and stroke. Lowering treatment costs per patient for common conditions can help slow spending for chronic conditions, but most of the increase in spending in the study period was the result of more patients seeking care from VA providers and the higher prevalence of conditions among patients. As the VA patient population continues to age and to develop more co-morbidities, and as returning veterans seek care for service-related problems, higher spending on chronic conditions will become a more prominent issue for the VA health care system.

Abstract
BACKGROUND AND PURPOSE Stroke is a leading cause of disability. Rehabilitation robotics have been developed to aid in recovery after a stroke. This study determined the additional cost of robot-assisted therapy and tested its cost-effectiveness. METHODS We estimated the intervention costs and tracked participants' healthcare costs. We collected quality of life using the Stroke Impact Scale and the Health Utilities Index. We analyzed the cost data at 36 weeks postrandomization using multivariate regression models controlling for site, presence of a prior stroke, and Veterans Affairs costs in the year before randomization. RESULTS A total of 127 participants were randomized to usual care plus robot therapy (n=49), usual care plus intensive comparison therapy (n=50), or usual care alone (n=28). The average cost of delivering robot therapy and intensive comparison therapy was $5152 and $7382, respectively (P<0.001), and both were significantly more expensive than usual care alone (no additional intervention costs). At 36 weeks postrandomization, the total costs were comparable for the 3 groups ($17 831 for robot therapy, $19 746 for intensive comparison therapy, and $19 098 for usual care). Changes in quality of life were modest and not statistically different. CONCLUSIONS The added cost of delivering robot or intensive comparison therapy was recuperated by lower healthcare use costs compared with those in the usual care group. However, uncertainty remains about the cost-effectiveness of robotic-assisted rehabilitation compared with traditional rehabilitation. Clinical Trial Registration- URL: http://clinicaltrials.gov.
