A model was developed that included both acute VTE (represented as a decision tree) and long-term complications (represented as a Markov process with one-year cycles). Transition probabilities were derived from phase III clinical trials comparing rivaroxaban with enoxaparin and published literature. Costs were derived from the Ontario Case Costing Initiative and publicly available sources. Utilities were derived from published literature. The model reported VTE event rates, quality-adjusted life expectancy and direct medical costs over a five-year horizon. Costs are reported in 2007 Canadian Dollars (C$). When rivaroxaban and enoxaparin are compared in patients undergoing THR, rivaroxaban enoxaparin. That is, rivaroxaban is associated with improved health outcomes as measured by increased quality-adjusted life years (QALYs; ) and fewer symptomatic VTE events (0.0061), and also with lower cost (savings of C$300) per patient. Similarly, rivaroxaban enoxaparin in patients undergoing TKR, achieving a gain of QALYs, a reduction of symptomatic venous thromboembolic events and savings of C$129 per patient. Rivaroxaban is a costeffective alternative to enoxaparin for VTE prophylaxis in patients undergoing THR and TKR. Over a five-year horizon, rivaroxaban dominated enoxaparin in the prevention of VTE events in patients undergoing THR and TKR, providing more quality-of-life benefit at a lower cost.

Potential thromboembolic DVT usually originates in the large deep distal veins of the lower limbs and tends to be asymptomatic, unless fractured thrombi metastasise as emboli, or morbid sequelae develop (4). Thrombi which propagate into the proximal veins are more likely to embolise (5) and cause pulmonary obstruction, with risk of death. Long-term complications (LTC) that can arise from VTE include recurrent VTE (6), the post-thrombotic syndrome (PTS) (7) and chronic thromboembolic pulmonary hypertension (8). VTE is the third leading cause of cardiovascular death in the US after myocardial infarction and stroke (9). Major orthopaedic surgery such as total hip replacement (THR) and total knee replacement (TKR) is associated with an increased risk of VTE (10). Estimates indicate that VTE may occur in 40 60% of patients undergoing major orthopaedic surgery with prophylactic therapy (11). In Canada, the number of patients undergoing elective THR and TKR has increased by more than 100% over the last 10 years, with 28,045 THR and 40,701 TKR operations in 2005/6 (12). In response to the risks associated with VTE, the American College of Chest Physicians currently recommends that patients receive prophylaxis for a minimum of 10 days and up to 35 days after THR, and suggest prophylaxis for 35 days after TKR (11). In addition, in the UK the National Institute for Health and Clinical Excellence recommend extended prophylaxis for four weeks after surgery for THR patients with one or more risk factors for VTE (13). The most commonly used method of VTE prophylaxis in Canada is parenterally administered low-molecular-weight heparins (LMWHs) such as enoxaparin and dalteparin (12). Rivaroxaban is a novel, once-daily, orally administered thromboprophylactic agent. It is a direct factor Xa inhibitor that demonstrates activity against both clot-associated and free factor Xa, as well as inhibiting prothrombinase activity and reducing thrombin generation (14, 15). In addition to being orally administered, un- Thrombosis and Haemostasis 104.4/2010

2 Diamantopoulos et al. Cost-effectiveness of rivaroxaban 761 like warfarin rivaroxaban does not require any monitoring during administration. Phase III clinical trials have demonstrated that rivaroxaban has superior efficacy compared with enoxaparin in terms of reducing VTE events, and a similar safety profile, after THR and TKR (16 19). Other new agents are also being investigated for the prevention of thromboembolic events after THR or TKR (20, 21). A cost-effectiveness analysis was conducted in order to evaluate the incremental cost per quality-adjusted life year (QALY) gained of rivaroxaban 10 mg once daily (od) compared with enoxaparin 40 mg od over a five-year time horizon for the prophylaxis of VTE in Canadian patients undergoing THR or TKR from the provincial government payer s perspective. Methods A decision-analytic model was developed to evaluate the cost-effectiveness of rivaroxaban compared with enoxaparin as prophylaxis for VTE in patients undergoing THR and TKR from a Canadian provincial government perspective. The analysis of the THR population compared 35 days of rivaroxaban with 35 days of enoxaparin (based on the REgulation of Coagulation in ORthopaedic surgery to prevent Deep vein thrombosis and pulmonary embolism REC- ORD1 clinical trial) (16), and the TKR population analysis compared 14 days of rivaroxaban with 14 days of enoxaparin (based on the RECORD3 clinical trial) (18). A five-year time horizon was used for the analysis base case and a 5% discount rate (as required in Canada) was applied to costs and benefits occurring beyond year 1. Model structure The cost-effectiveness model extrapolates the observed event rates from the RECORD trials (i.e. during the prophylaxis module in the model) to project VTE events occurring between the end of the RECORD trials up to 90 days after surgery (i.e. the post-prophylaxis module in the model), and recurrent venous thromboembolic events and LTC occurring up to five years after surgery (i.e. the LTC module of the model). Thus the model is divided into three modules: prophylaxis, post-prophylaxis, and LTC. The first two modules are represented with a decision tree (see Fig. 1), and the third module is developed as a Markov process (see Fig. 2). The first module is related to the outcomes in the RECORD clinical trials (i.e. five weeks for THR, two weeks for TKR). The prophylaxis module includes VTE events occurring during index hospitalisation and those occurring after discharge from hospital. The events considered in the prophylaxis module are: major bleeding, asymptomatic VTE, symptomatic DVT, non-fatal PE, and fatal PE. Asymptomatic VTEs are used for the extrapolation process, but do not result in costs or utility decrements in and of themselves. Data suggest that patients are at risk of developing VTE for up to three months after surgery (22). Because the clinical trials report VTE events up to the time of venography, the probability of patients with an asymptomatic event detected by venography who would subsequently develop a symptomatic VTE is not available from clinical trial data. The model therefore extrapolates for the proportion of venographically confirmed asymptomatic events that would become symptomatic between the end of prophylaxis and 90 days after surgery. This is the post-prophylaxis module (23). Rebound VTE were not included in the model as there was no evidence from the RECORD programme, including the follow-up period, that rebound occurred and therefore it was not considered relevant. Three months after surgery, patients progress to the LTC module. The LTC module reflects the risk of PTS and recurrent VTE. During this module, patients who have experienced a VTE are at risk of developing PTS and having a recurrent VTE. As shown in Figure 2, the Markov model contains three health states: no PTS, PTS, and death due to all-cause mortality. For completeness the analysis considers background mortality risk, however, this does not impact the incremental results. The LTC phase is analysed Figure 1: Decision tree.

PTS, post-thrombotic syndrome. using a Markov process with one-year cycles. Half-cycle correction is applied to the model outcomes. The risk of developing LTC (PTS and recurrent VTE) varies depending on time after surgery and is modelled with time-dependent transition probabilities ( Table 1). All individuals who experienced DVT or PE in previous modules (prophylaxis or extrapolation period) are at risk of recurrent VTE and PTS. The incidence of recurrent VTE is modelled as a transitory event rather than a health state; that is, patients incur the VTE cost and disutility regardless of health state membership. Due to the absence of data, the model assumes that all recurrent VTE events are DVTs. Because PTS is a chronic condition, once developed, patients cannot regress back to a no PTS health state. The model assumes that the entire cohort is at risk of death based on background mortality, which is the same for all individuals in the model regardless of the health state, and is based on Canadian life tables (24). Transition probabilities Prophylaxis module For THR, the prophylaxis module of the model was populated with efficacy and safety data from RECORD1, which compared five weeks of prophylaxis with rivaroxaban to five weeks of prophylaxis with enoxaparin. For TKR, the prophylaxis module of the model was populated with data from RECORD3, which compared two weeks of prophylaxis with rivaroxaban to two weeks of prophylaxis with enoxaparin. The model incorporates differences in event rates between comparators if statistically significant differences were observed in the RECORD clinical trials. If statistically significant differences have not been observed, the event rate observed in the RECORD trial for the rivaroxaban arm is used. The rivaroxaban arm was selected as an indication of baseline risk because it produces more conservative results in terms of cost-effectiveness. Sensitivity analysis was performed on the alternative scenario, where the observed events from the enoxaparin arm are used as baseline risk. Because the results of the clinical trials did not show any statistically significant differences in PE events or prophylaxis-related major bleeding between the two comparators, the model assumes parity between the two comparator arms for these event risks. A sensitivity analysis was also conducted using the numerical differences for these event rates from the RECORD trials. Extrapolation from prophylaxis to post-prophylaxis module The proportion of the cohort that developed an asymptomatic event during the RECORD trials (i.e. RECORD1 for THR and RECORD3 for TKR) was assumed to be at risk of a symptomatic event up to 90 days after surgery (22). The extrapolation of asymptomatic to symptomatic events was based on a study published by Quinlan et al. (23). This study compared the incidence of asymptomatic DVT in THR and TKR studies where venography was routinely performed with the incidence of symptomatic VTE in THR and TKR studies where venography was not performed. The authors reported a consistent relationship between symptomatic VTE and asymptomatic DVT for the THR (ratio of 1:5) and TKR (ratio of 1:2) populations. This results in an estimated probability of asymptomatic VTE developing into symptomatic VTE of approximately 20% for the THR and 5% for the TKR model cohorts. The proportion of VTE patients who experience a PE vs. those with a DVT was reported by White et al. (25), and this relationship was combined with the symptomatic incidence reported by Quinlan et al. (23), in order to estimate the stable risk of DVT and PE after the clinical trial module (Table 1). Thrombosis and Haemostasis 104.4/2010 Schattauer 2010

(36) calculated Year 1 5 *Quinlan et al (23) report the probability of developing symptomatic VTE after asymptomatic DVT. The model therefore assumes that asymptomatic DVT is equal to asymptomatic VTE (i.e. no patients experience an asymptomatic PE). The ratio of DVT:PE in the post-prophylaxis period is based on White et al (25). DVT, deep-vein thrombosis; PE, pulmonary embolism; PTS, postthrombotic syndrome; THR, total hip replacement; TKR, total knee replacement; VTE, venous thromboembolism. Extrapolation for LTC module The probability of developing PTS was derived from a published epidemiological study in European patients (26). All individuals who experienced a symptomatic DVT in previous modules (prophylaxis or post-prophylaxis) are at risk of developing PTS. This includes the approximate 37% of patients who have suffered a PE after a DVT (8, 27, 28). In this extrapolation it was assumed that the risk of an asymptomatic event becoming symptomatic is the same regardless of the prophylaxis used any differences are driven by the different proportion of patients with an asymptomatic event during the prophylaxis phase of the model. All patients who suffered a symptomatic DVT or PE in the previous modules were also at risk of developing a recurrent VTE. The proportion of patients developing a recurrent VTE was based on the incidence of recurrent VTE in patients with a first episode of VTE provoked by a transient risk factor (approximately 3.2% per year) (29). The model assumes that all recurrent VTE events are DVTs. Utility values Utility values for each health state were obtained from published literature. Utility scores are adjusted to reflect the duration of the corresponding events. The utility values used in this analysis and the source of the values are shown in Table 2. It was assumed that patients who have just undergone THR or TKR surgery had a reduced background utility of and 0.805, respectively, for the first year Schattauer 2010 Thrombosis and Haemostasis 104.4/2010

The impact of assuming a lower background utility after the 1 st year is assessed in a sensitivity analysis. These values were used to weight the utility of any events (bleeding, DVT, PE, or PTS) (31, 32) occurring during the course of the analysis. For patients who experienced more than one event in the same cycle (year), the worst utility value was applied in that cycle with the exception of recurrent VTE, which was modelled as a disutility for a period of three months of the one-year Markov cycle. Costs Costs related to prophylaxis, VTE treatment, LTC, and bleeding were included in the model ( Table 3). The duration of prophylaxis was based on the relevant RECORD trial. The duration of hospitalisation was obtained from the Canadian Joint Registry Replacement Annual report (12) and was incorporated in calculating the inhospital, post-discharge, and total prophylaxis drug cost per course. Pharmacy mark-up and dispensing fees, based on Ontario allowances, were added to the daily drug cost after discharge. It was conservatively assumed that no costs were incurred for the administration or monitoring of prophylaxis while in hospital. However, it was assumed that 19% of patients receiving an injectable method of prophylaxis would be unable to self-inject and would, therefore, require nurse assistance once discharged from the hospital (33). This is consistent with previous Canadian economic evaluations, which have included nursing homecare visits for up to 39% of patients receiving LMWH therapy (34). Outpatient monitoring costs were also conservatively assumed to be zero for all methods of prophylaxis. Costs incurred in hospital (such as those for inpatient management of VTE and diagnostic testing costs) were obtained from the Ontario Case Costing Initiative (OCCI) (35), an undertaking of the Ontario Ministry of Health and Long-Term Care that collects case cost data for acute inpatient, day surgery, and ambulatory care cases. Patients experiencing a non-fatal prophylaxis-related bleeding event were assigned the OCCI-derived cost of a major bleeding event occurring in hospital in patients who had undergone THR and TKR. Due to small patient numbers, it was not possible to obtain the cost of fatal bleeding specifically in patients undergoing THR or TKR, so the average cost of a fatal bleeding event occurring after admission was used instead. Although this average cost may differ from the cost of fatal bleeding occurring in THR or TKR patients, the proportion of the cohort experiencing a fatal bleeding event is very small, and thus the model is very insensitive to this input. Minor bleeds were assumed not to incur a cost or quality-of-life impact and so were excluded from the model. The cost of treating patients who develop a VTE event during their index hospitalisation (i.e. while still in hospital after surgery) and the associated length of stay were calculated by subtracting the OCCI average cost for patients undergoing THR or TKR from the OCCI cost of patients who have undergone THR or TKR and also had a DVT or PE. Of those patients whose VTE event occurred after discharge, it was assumed, based on published Canadian sources (34), that 10% of DVT patients and 67% of PE patients were re-admitted to hospital for VTE management. The cost and length of stay for treating readmitted DVTs and PEs were obtained from the OCCI using the cost of DVTs and PEs coded as the most responsible diagnosis or the main pre-admission diagnosis for patients who were discharged (35). All patients treated for VTE in hospital were assumed to receive warfarin after discharge and incur some outpatient follow-up costs based on Skedgel et al. (34). Physician fees were not included in the OCCI costs and, therefore, for events occurring Thrombosis and Haemostasis 104.4/2010 Schattauer 2010

Rivaroxaban Rivaroxaban Rivaroxaban Rivaroxaban either during index hospitalisation or after discharge, the cost of a daily physician visit, derived from the Ontario Schedule of Benefits (36), was added for the VTE-related duration of hospital stay. Resource use associated with outpatient management of VTE was based on the Canadian economic analysis reported by Skedgel et al. (34), and updated costs for each of the resource use items were obtained from a number of publicly available sources, including the Ontario Schedule of Benefits and the Ontario Drug Benefit Formulary (Table 3) (36, 37). The baseline analysis was conducted for a five-year timeframe, which allowed the impact of LTC to be incorporated. In order to assess the impact of rivaroxaban in the short term, one-way sensitivity analyses (SA) based on the prophylaxis and post-prophylaxis phases only were performed. A number of one-way sensitivity analyses were also conducted on the baseline assumptions in order to examine the effect of potential variations in clinical practice, costs, and event rates. Parameters tested included outpatient administration costs associated with enoxaparin, discount rates, and event treatment costs. A sensitivity analysis incorporating differences in bleeding and VTE rates that were numerically but not statistically different was also conducted. Because dalteparin is a frequently used LMWH in Canada, a sensitivity analysis comparing rivaroxaban with dalteparin in THR and TKR was also done. This analysis assumed that the efficacy and safety of LMWHs are not different and, therefore, used enoxaparin efficacy and safety inputs for the dalteparin arm. Given that there is not a universally accepted perfect health utility value in Canada, the value of 1 was selected for patients with no longterm VTE complications. A SA considers utility weighting based on a UK study (38). Probabilistic sensitivity analyses (PSAs) were performed to address uncertainty at the parameter level (2,000 samples). The parameters of the model that were sampled include drug administration and monitoring costs, prophylaxis-related bleeding costs, diagnosis and treatment costs, DVT and PE treatment costs, LTC costs, utility values and event probabilities for the prophylaxis, post-prophylaxis, and LTC modules (distributions were generated using 95% confidence intervals or standard deviation, depending upon the parameter). Results Sensitivity analyses Deterministic analysis The base case analyses indicate that, when 35 days of prophylaxis with rivaroxaban and enoxaparin are compared in patients undergoing THR, rivaroxaban enoxaparin. That is, it is associated with greater benefit ( QALYs), fewer symptomatic VTE events (0.0061), and lower cost (savings of C$300) per patient. Similarly, when rivaroxaban and enoxaparin are compared in patients undergoing TKR, rivaroxaban enoxaparin, achieving a gain of QALYs, a reduction of symptomatic VTEevents, and savings of C$129 per patient (see Table 4). One-way sensitivity analysis Sensitivity analyses considering only the acute phase (prophylaxis and post-prophylaxis phases) indicate that rivaroxaban is a costeffective method of VTE prophylaxis when compared with enoxaparin in both a THR and a TKR population: rivaroxaban dominated enoxaparin in both THR and TKR populations, providing more benefit at less cost ( Table 5). In the sensitivity analysis where it is assumed the non-statistically-significant event risk is replaced by the enoxaparin group observed event risk instead of rivaroxaban, the cost-effectiveness Thrombosis and Haemostasis 104.4/2010 Schattauer 2010

8 Diamantopoulos et al. Cost-effectiveness of rivaroxaban 767 results of the THR analysis remain the same. This is because in the THR population only VTE event is statistically significant and since all others are symmetrically reversed the incremental cost and incremental effects are unchanged. In the TKR population symptomatic VTE events are also statistically significant which results in changes to the calculations of symptomatic DVT and asymptomatic VTE events. In this scenario the incremental costsaving is increased to approximately C$379 and the incremental quality of life benefit to QALYs. Rivaroxaban remains the dominant intervention. For patients undergoing TKR, rivaroxaban continued to dominate enoxaparin in all scenarios tested. For patients undergoing THR, rivaroxaban was less costly and more effective than enoxaparin in all but one scenario. When using the results from RECORD2, where patients were administered with rivaroxaban for 35 days and enoxaparin for 14 days, the cost per QALY was approximately C$24,977 which is well below the frequently-referenced cost-effectiveness threshold of C$50,000/QALY. Probabilistic sensitivity analysis The results of the PSAs for THR and TKR are shown via cost-utility analysis (CUA) planes in Figures 3 and 4, respectively. For THR, all of the iterations appear in the lower half of the CUA plane, indicating that 35 days of rivaroxaban is less costly compared with 35 days of enoxaparin. In addition, nearly all of the iterations appear in the lower right quadrant of the CUA plane, indicating that 35 days of rivaroxaban is less costly and more effective compared with 35 days of enoxaparin ( Fig. 3). For TKR, all simulations appear in the bottom right quadrant ( Fig. 4), indicating that 14 days of rivaroxaban is less costly and more effective than 14 days of enoxaparin in terms of preventing VTE events after TKR. Both PSAs and the one-way sensitivity analyses suggest that the finding of dominance for rivaroxaban relative to enoxaparin improved health outcomes at a lower cost is robust.

9 768 Diamantopoulos et al. Cost-effectiveness of rivaroxaban Figure 3: Total hip replacement cost-utility analysis plane (quality-adjusted life years). Discussion Rivaroxaban is an orally administered agent that does not require any monitoring during administration for the prevention of VTE. The efficacy and safety of rivaroxaban have been demonstrated in four large phase III randomised controlled trials, where rivaroxaban showed a statistically significant improvement over enoxaparin in the primary endpoint of total VTE (16, 19). Rivaroxaban also showed no statistically significant difference relative to enoxaparin in the occurrence of major bleeding or clinically relevant non-major bleeding. The lack of difference in bleeding events between rivaroxaban and enoxaparin indicate there is no difference in incremental costs associated with these events. The base case cost-effectiveness analyses for rivaroxaban in THR and TKR show that rivaroxaban enoxaparin, providing more benefit at less cost in both populations. In addition to providing increased QALYs relative to enoxaparin, rivaroxaban also leads to fewer symptomatic VTE events than enoxaparin. Rivaroxaban is expected to prevent an additional six symptomatic VTE events relative to enoxaparin per 1,000 THR procedures. For TKR, rivaroxaban is expected to prevent an additional 19 events per 1,000 procedures. The sensitivity of the model results to changes in various parameters was evaluated using one-way deterministic sensitivity analyses. Moreover, uncertainty around model parameters was addressed by PSA. For the deterministic sensitivity analyses, rivaroxaban dominated enoxaparin in all scenarios for the TKR population and in the majority of scenarios for THR. The PSA shows that the results of the economic evaluation are robust. Several potential benefits associated with rivaroxaban thromboprophylaxis, compared with enoxaparin, had not been taken into account in this analysis. First, it had been suggested that the method of administration (oral vs. parenteral) may have some effect on patients utility. However, as no data had been identified to support this hypothesis, disutility associated with injections was not included in this model. Similarly, although no in-hospital drug administration costs had been included in the analysis, enoxaparin injections administered in hospital would likely be performed by a nurse or other healthcare professional, and may therefore be associated with higher professional costs when compared with oral rivaroxaban. Furthermore, in Canada, when LMWHs are administered regular monitoring for heparin-induced thrombocytopenia is recommended, but costs associated with such monitoring had not been included in this analysis. Because enoxaparin is administered as a parenteral injection and rivaroxaban is taken orally, the inclusion of any disutility or additional cost associated with injectable prophylaxis would change the results of this analysis in favour of rivaroxaban. In addition, in Canada, many tertiary care hospitals have anticoagulation clinics to manage discharged patients. Services offered at these clinics include nurse-assisted injection of LMWHs and monitoring of warfarin. The cost of operating these clinics and thus of managing prophylaxis after hospital discharge can be substantial. Because rivaroxaban does not require routine monitoring or assisted administration, it is not anticipated that such clinic visits would be required. In order to remain conservative, the clinic costs for patients receiving LMWHs were not included in the analysis. However, even when administration costs were excluded rivaroxaban was highly cost-effective. Thrombosis and Haemostasis 104.4/2010 Schattauer 2010

10 Diamantopoulos et al. Cost-effectiveness of rivaroxaban 769 Figure 4: Total knee replacement cost-utility analysis plane (quality-adjusted life years). The model structure is based on published recommendations and previously conducted economic evaluations, and, therefore, represents best practice of economic modelling in this area. Moreover, the economic evaluation is based on the clinical trial data and all the cost and resource use assumptions in the model are from publicly available sources. As indicated by the scenario analyses overall results of the model are robust to variations in its inputs. As with any economic model, there are limitations with the approach taken in this analysis. Although the prophylaxis module of the model was based on clinical trial data, the assumptions and values used in the post-prophylaxis and LTC modules were based on the literature. Rebound thromboembolic effects were not included in the model, as the results are driven by the reduced administration requirements and reduced symptomatic and asymptomatic events. Therefore the inclusion of rebound effects is unlikely to have changed the overall conclusions. The parameter of clinically relevant non-major bleeding was excluded from the model because expert advice indicated the likely impact on resource use was very low, as was the impact on health-related quality of life. Furthermore, several different sources were required to ascertain the utility values to populate the model. Although the resource use and cost data were taken from Canadian sources, it was not possible to source Canadian data for all transition probabilities, and utilities used in the model. However, extensive sensitivity analyses (both oneway and probabilistic sensitivity analyses) showed that the key findings of rivaroxaban being a highly cost effective anticoagulant remained unchanged. Conclusion In summary, rivaroxaban is the first oral, direct factor Xa inhibitor available for VTE prophylaxis in patients undergoing THR and What is known about this topic? Before the introduction of novel oral anticoagulants, prophylaxis with low-molecular-weight heparins (LMWHs), such as enoxaparin, was the standard of care after total hip or knee replacement (THR, TKR) in Canada. The cost-effectiveness of enoxaparin in Canada, and elsewhere, has been established in the literature for some years. The only published economic analysis of rivaroxaban in this indication is in the setting of Ireland (McCullagh et al. 2009); it shows rivaroxaban to be more effective and less expensive vs. enoxaparin prophylaxis after THR and TKR (based only on short-term events). What does this paper add? It demonstrates that a decrease in short-term thrombotic events (deep-vein thrombosis and pulmonary embolism) reduces healthcare costs associated with treating these events, as well as the cost associated with longer-term complications of these events (recurrent events and post-thrombotic syndrome). In Canada, the improved health outcomes with rivaroxaban translate into reduced healthcare costs (even when drug prices are included) relative to LMWHs. These findings confirm the results of the Irish analysis (which was based on a different model). Schattauer 2010 Thrombosis and Haemostasis 104.4/2010

11 770 Diamantopoulos et al. Cost-effectiveness of rivaroxaban TKR. It has demonstrated meaningful improvements in efficacy relative to enoxaparin and also has a positive health economic profile, providing more benefit at less cost relative to enoxaparin in THR and TKR patients. The convenience of rivaroxaban, combined with its improved efficacy and economic benefits over enoxaparin, suggests that rivaroxaban is a cost-effective option for VTE prophylaxis in both patient populations.
