Cost-effectiveness analysis of cytomegalovirus prophylaxis in allogeneic hematopoietic cell transplant recipients from a US payer perspective.

To evaluate the cost-effectiveness of letermovir versus no prophylaxis for the prevention of cytomegalovirus infection and disease in adult cytomegalovirus-seropositive allogeneic hematopoietic cell transplantation (allo-HCT) recipients. A decision model for 100 patients was developed to estimate the probabilities of cytomegalovirus infection, cytomegalovirus disease, various other complications, and death in patients receiving letermovir versus no prophylaxis. The probabilities of clinical outcomes were based on the pivotal phase 3 trial of letermovir use for cytomegalovirus prophylaxis versus placebo in adult cytomegalovirus-seropositive recipients of an allo-HCT. Costs of prophylaxis with letermovir and of each clinical outcome were derived from published sources or the trial clinical study reports. Incremental cost-effectiveness ratios (ICERs) in terms of cost per quality-adjusted life year (QALY) gained were used in the model. One-way and probabilistic sensitivity analyses were conducted to explore uncertainty around the base-case analysis. In this model, the use of letermovir prophylaxis would lead to an increase of QALYs (619) and direct medical cost ($1 733 794) compared with no prophylaxis (578 QALYs; $710 300) in cytomegalovirus-seropositive recipients of an allo-HCT. Letermovir use for cytomegalovirus prophylaxis was a cost-effective option versus no prophylaxis with base-case analysis ICER $25 046/QALY gained. One-way sensitivity analysis showed the most influential parameter was mortality rate. The probabilistic sensitivity analysis showed a 92% probability of letermovir producing an ICER below the commonly accepted willingness-to-pay threshold of $100 000/QALY gained. Based on this model, letermovir use for cytomegalovirus prophylaxis was a cost-effective option in adult cytomegalovirus-seropositive recipients of an allo-HCT.

Comparative effectiveness of budesonide inhalation suspension and montelukast in children with mild asthma in Korea.

Objective: The comparative effectiveness of low-dose budesonide inhalation suspension (BIS) versus oral montelukast (MON) in managing asthma control among children with mild asthma was assessed in Korea.Methods: Claims from Korea's national health insurance database for children (2-17 years) with mild asthma (GINA 1 or 2) who initiated BIS or MON during 2015 were retrospectively analyzed. Pre- and post-index windows were 1 year each. Adherence, persistency, asthma control, asthma-related health-care resource utilization, and costs were evaluated using unadjusted descriptive statistics and propensity score-matched regression analyses.Results: The number of children identified was 26,052 for unmatched (n = 1,221 BIS; n = 24,831 MON) and 2,290 for matched populations (n = 1,145 per cohort). Medication adherence, measured by proportion of days covered, was low for both cohorts but significantly higher for MON versus BIS (13.8% vs. 4.5%; p < .001). Time to loss of persistency was longer for MON versus BIS (82.3 vs. 78.4 days, respectively; p < .001). Mean number of post-index asthma-related office visits was 6.6 for BIS versus 8.3 for MON (p < .001). However, a greater proportion of patients in the BIS cohort had an asthma exacerbation-related office visit than the MON cohort (78.3% vs. 56.1%; p < .001). Asthma-related total health-care costs were higher with MON versus BIS (₩ 190,185 vs. ₩ 167,432, respectively; p < .001), likely driven by higher pharmaceutical costs associated with MON (₩ 69,113 vs. ₩ 49,225; p < .001).Conclusions: Montelukast patients had better adherence, a longer time to loss of persistency, and were less likely to experience an exacerbation-related office visit in the post-index period than BIS patients.

[The patients' cost of the montelukast therapy due to the generic substitution]. / A montelukasztterápia betegterheinek változása a generikus árverseny hatására.

INTRODUCTION AND AIM: The aim of our study was to analyse the public price of the montelukast sodium therapy in Hungary. METHOD: Data derived from the nationwide pharmaceutical database of the Hungarian National Health Insurance Fund Administration. We observed the turnover and price of the medicaments containing the active substance montelukast sodium from 2007 to 2015. Accordingly, our indicators were: consumer price, DCT (daily cost of therapy), co-payment, quasi co-payment, DOT (days of treatment). RESULTS: Due to the increasing DOT, the total amount of the public price paid by the patients increased until 2011, reaching the amount of 1 million USD; then, due to the generic competition and the blind bid methods, it decreased to 490 000 USD. The total amount of the public price of the brand-name Singulair moved to the generics during 3 years (2011-2014). The DCT of the originator Singulair 10 mg tablets decreased from 1.1 USD to 0.34 USD; the DCT of the generic product Montelukast TEVA decreased from 0.67 USD to 0.16 USD in the period under review. CONCLUSION: Due to the generic competition, the patients' access to drugs containing montelukast sodium increased significantly: the DOT increased, the co-payment decreased.

A Real-world Cost-effectiveness Analysis of Sevelamer Versus Calcium Acetate in Korean Dialysis Patients.

PURPOSE: Sevelamer, a noncalcium phosphate binder, has been shown to attenuate the progression of vascular calcification and improve survival in patients with chronic kidney disease undergoing dialysis compared with calcium-based binders. Using real-world data from a cohort study and the Health Insurance Review and Assessment Service database, we conducted a cost-effectiveness analysis comparing sevelamer with calcium acetate in dialysis patients from the perspective of the National Health Insurance Service in South Korea. METHODS: Data (demographic, diagnostic, laboratory, and survival) from 4674 patients undergoing dialysis enrolled in a multicenter prospective cohort study conducted in South Korea between September 2008 and December 2012 were linked to phosphate binder use, hospitalization, and cost data available from the Health Insurance Review and Assessment Service database. After propensity score matching, a dataset comprising comparable patients treated with either sevelamer (n = 501) or calcium acetate (n = 501) was used in the cost-effectiveness analysis. A Markov model was used to estimate costs, life years, quality-adjusted life years (QALYs), and cost-effectiveness over each patient's lifetime. Forty-month treatment-specific overall survival (OS) data available from the dataset were extrapolated to lifetime survival with the use of regression analysis. FINDINGS: Patients had a mean age of 56.3 years and were treated with dialysis for a mean duration of 67.6 months. Compared with calcium acetate, sevelamer was associated with an incremental cost of South Korean Won (₩) 12,246,911 ($10,819) and a gain of 1.758 life years and 1.108 QALYs per patient. This outcome yielded incremental cost-effectiveness ratios of ₩6,966,350 ($6154) and ₩11,057,699 ($9768) per life year and QALY gained, respectively. Conclusions regarding sevelamer's cost-effectiveness were insensitive to alternative assumptions in time horizon, discount rate, hospitalization rate, costs, and health utility estimates, and they remained consistent in 100% of the model iterations, considering a willingness-to-pay threshold of ₩31,894,720 ($28,176) per QALY gained. IMPLICATIONS: This analysis of real-world data found that sevelamer's higher cost relative to calcium acetate was adequately offset by improved survival among patients undergoing dialysis in South Korea. As such, sevelamer offers good value for money, representing a cost-effective alternative to calcium-based binders.

Comparison of efficacy, safety, and cost-effectiveness of montelukast-levocetirizine and montelukast-fexofenadine in patients of allergic rhinitis: A randomized, double-blind clinical trial.

OBJECTIVES: Allergic rhinitis (AR) is a global health problem. Almost 10%-25% of population worldwide is affected by AR. Oral/intranasal H1-antihistamine, decongestants, leukotriene receptor antagonists, and intranasal corticosteroids are the pillars in the management of AR. The combination therapy of montelukast with antihistaminic provides enhancing and complimentary effects, thereby reducing the symptoms effectively, but there are scanty data regarding the comparisons of combinations. Therefore, we aimed to compare the efficacy, safety, and cost-effectiveness of montelukast-levocetirizine and montelukast-fexofenadine combination in patients of AR. MATERIALS AND METHODS: Seventy patients with AR participated in a prospective, randomized, double-blind, parallel, active-controlled, comparative 4-week trial. The patients between the age group of 18-65 years of either gender having moderate-severe intermittent or mild persistent AR were included in the study. The study inclusion criteria required the patients with total nasal symptom score (TNSS) of 5 or higher. The patients were randomly divided into two treatment groups with montelukast-levocetirizine (10 mg and 5 mg) in one group and montelukast-fexofenadine (10 mg and 120 mg) in another group. TNSS parameter was the main effectiveness parameter. RESULTS: Evaluation of TNSS revealed significant difference (P < 0.05) when compared from baseline to 4th week in both groups. The mean change of TNSS, i.e., 9.46 was significant (P < 0.05) in montelukast-fexofenadine group. The cost-effectiveness ratio was less in montelukast-levocetirizine group than in montelukast-fexofenadine group. CONCLUSION: The decrease in TNSS was more in montelukast-fexofenadine group, but the cost-effectiveness is more with montelukast-levocetirizine combination.

[The effect of generic price competition on drug consumption and health insurance pharmaceutical expenditures in Hungary]. / A generikus árverseny hatása a gyógyszerforgalomra es a társadalombiztosítási támogatás kiáramláisra Magyarországon.

AIM: The aim of our study was to analyze the Hungarian montelukast sodium drug market. We examined the effect of the appearance of generic drugs on the price and turnover of the brand-name drug, Singulair. DATA AND METHODS: Data derived from the nationwide pharmaceutical database of Hungarian National Health Insurance Fund Administration (2007-2014). We analized the turnover and price of the medicaments containing the active substance montelukast sodium. Accordingly our indicators were: consumer price, social insurance subsidy, patients' co-payment and days of treatment (DOT). RESULTS: First the generics started from a significantly lower price of 18 USD which was lower than the price of brand-name Singulair (32 USD). Then the prices of the generics started to diminish. While in 2007 the DOT was below 2 million, it increased over 10 million days by 2014. The increase of DOT was followed by the increase of health insurance subsidy until 2011. Then the amount of health insurance subsidy decreased from 10,5 million USD to 7 million USD in 2012. In 2013 and 2014 there was a further reduction, the amount of the health insurance subsidy decreased to 4,1 million USD in 2013, and in 2014 it was reduced to 2.2 million USD. CONCLUSIONS: Following the introduction of generic drugs, the price of the medicaments containing montelukast sodium was significantly reduced, while the days on treatment (DOT) increased. The patients' access to drugs containing montelukast sodium increased significantly. The annual health insurance subsidy was significantly reduced as well.

Management of hyperphosphataemia in chronic kidney disease: summary of National Institute for Health and Clinical Excellence (NICE) guideline.

Bone disease and ectopic calcification are the two main consequences of hyperphosphataemia of chronic kidney disease (CKD). Observational studies have demonstrated that hyperphosphataemia in CKD is associated with increased mortality. Furthermore, the use of phosphate binders in dialysis patients is associated with significantly lower mortality. The UK Renal Registry data show significant underachievement of phosphate targets in dialysis patients. It is believed to be due to wide variation in how management interventions are used. The National Institute for Health and Clinical Excellence (NICE) has developed a guideline on the management of hyperphosphataemia in CKD. This is based on the evidence currently available using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. This review outlines the recommendations including research recommendations and discusses methodology, rationale and challenges faced in developing this guideline and the health economic model used to assess the cost-effectiveness of different phosphate binders.

[Cost effectiveness of treatment with salmeterol/fluticasone compared to montelukast for the control of persistent asthma in children]. / Costo-efectividad del tratamiento de salmeterol/fluticasona en comparación con leucotrieno montelukast para el control del asma infantil.

OBJECTIVE: To assess the incremental cost-effectiveness of SFC compared with MON for the control of persistent asthma in children. METHODS: We conducted an economic evaluation on a 12-week prospective randomized open-label parallel-group comparison of SFC versus MON in children with symptomatic asthma receiving inhaled corticosteroids and short-acting ß2-agonists. Asthma-related medication, unscheduled physician contacts and hospitalizations were collected prospectively. The main effectiveness measure was percentage of asthma-controlled week with no short-acting ß2-agonist use during the study period. The analysis was conducted from the Mexican healthcare perspective using 2010 unit cost prices, and only direct costs were considered, all costs are reported in US dollar. . The model was made fully probabilistic to reflect the joint uncertainty in the model parameters. RESULTS: Over the whole treatment period, the median percentages of asthma-controlled weeks were 83.3% in the SFC group and 66.7% in the MON group (SFC-MON difference, 16.7%; 95% CI, 8.3-16.7; P < 0.001 in favor of SFC). The mean total cost of the SFC regimen was $ 2,323 compared with $ 3,230 for the MON regimen. The SFC was the dominant strategy (both more effective and less expensive) using the SFC was associated with an incremental cost per additional asthma-controlled of $ (5,467). Probabilistic sensitivity analysis tested numerous assumptions about the model cost and efficacy parameters and found that the results were robust to most changes. CONCLUSIONS: This analysis demonstrates that, compared with MON, SFC may be cost saving from the Mexican health care perspective for the treatment of pediatric patients with asthma. SFC provided a reduction in the number of severe exacerbations, frequent asthma symptoms and rescue medication use. Incremental cost-effectiveness analysis indicated the dominance of SFC because of both lower costs and greater efficacy.

Cost-effectiveness analysis of fluticasone versus montelukast in children with mild-to-moderate persistent asthma in the Pediatric Asthma Controller Trial.

BACKGROUND: Cost-effectiveness analyses of asthma controller regimens for adults exist, but similar evaluations exclusively for children are few. OBJECTIVE: We sought to compare the cost-effectiveness of 2 commonly used asthma controllers, fluticasone and montelukast, with data from the Pediatric Asthma Controller Trial. METHODS: We compared the cost-effectiveness of low-dose fluticasone with that of montelukast in a randomized, controlled, multicenter clinical trial in children with mild-to-moderate persistent asthma. Analyses were also conducted on subgroups based on phenotypic factors. Effectiveness measures included (1) the number of asthma-control days, (2) the percentage of participants with an increase over baseline of FEV(1) of 12% or greater, and (3) the number of exacerbations avoided. Costs were analyzed from both a US health care payer's perspective and a societal perspective. RESULTS: For all cost-effectiveness measures studied, fluticasone cost less and was more effective than montelukast. For example, fluticasone treatment cost $430 less in mean direct cost (P < .01) and resulted in 40 more asthma-control days (P < .01) during the 48-week study period. Considering sampling uncertainty, fluticasone cost less and was more effective at least 95% of the time. For the high exhaled nitric oxide (eNO) phenotypic subgroup (eNO ≥25 ppb) and more responsive PC(20) subgroup (PC(20) <2 mg/mL), fluticasone was cost-effective compared with montelukast for all cost-effectiveness measures, whereas not all the effectiveness measures were statistically different for the other 2 phenotypic subgroups. CONCLUSION: For children with mild-to-moderate persistent asthma, low-dose fluticasone had lower cost and higher effectiveness compared with montelukast, especially in those with more airway inflammation, as indicated by increased levels of eNO and more responsivity to methacholine.

Cost and resource utilization comparisons of second-generation antihistamines vs. montelukast for allergic rhinitis treatment.

This study evaluates the costs and utilization burden associated with oral, branded second-generation antihistamines (BSGAs) compared with montelukast (MTLK) as first-choice treatment in newly diagnosed allergic rhinitis (AR) patients without asthma. We compared annual medical costs of illness and utilization changes from 1 year before index AR diagnosis to 1 year after for continuously enrolled AR patients initiating therapy with BSGA or MTLK. Multivariate regressions for each outcome variable adjusted for confounders including age, sex, geographic region, Charlson Comorbidity Index, RxRisk Score, 18 comorbidity groups, and payer type. Treatment selection bias was evaluated by propensity score with all covariates plus instrumental variables including physician type and likelihood of prescribing MTLK versus BSGA. Insurance claims data for the years 2003-2007 included AR patients in all regions of the United States. The final sample included 13,703 AR patients taking BSGAs (84%) or MTLK (16%). After confounder adjustment, MTLK patients experienced higher total medical costs ($1,542 versus $989), drug costs ($714 versus $477), AR drug costs ($474 versus $298), and outpatient visit costs ($480 versus $277) than BSGA patients (all values of p < 0.025). MTLK patients experienced higher total visits (0.96), AR outpatient visits (0.71), and comorbidity visits (0.12) than BSGA patients (all values of p < 0.01). MTLK patients were more likely to add additional AR therapy medications (MTLK, 43.2%; BSGA, 31.6%; p < 0.01). New AR patients prescribed MTLK as first-line medication therapy have higher medical costs and resource utilization than those prescribed first-line oral BSGAs. These differences persisted after adjustment for patient fixed effects, available confounders, and treatment propensity scores.

Economic evaluation of sevelamer versus calcium-based phosphate binders in hemodialysis patients: a secondary analysis using centers for Medicare & Medicaid services data.

BACKGROUND AND OBJECTIVES: A secondary analysis of the Dialysis Clinical Outcomes Revisited (DCOR) trial suggested that sevelamer reduced hospitalizations relative to calcium-based phosphate binders. However, whether changed medical costs associated with reduced hospitalizations or other medical services offset the higher cost of sevelamer is unclear. This DCOR secondary analysis aimed to (1) evaluate Medicare total, inpatient, outpatient, skilled nursing facility, and other costs in sevelamer-treated versus calcium-treated patients; (2) examine Medicare costs in specific categories to determine cost drivers; and (3) estimate and incorporate sevelamer and calcium binder costs. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: DCOR trial participants were linked to the Centers for Medicare & Medicaid Services ESRD database. Medicare costs for 1895 dosed Medicare-primary-payer participants were evaluated. Phosphate binder costs were incorporated. Costs were indexed to 2001 (study base year). Sensitivity analyses were performed with randomized participants, two follow-up periods, and 2004 as index year. RESULTS: Inflation-adjusted Medicare per member per month (PMPM) costs were lower for sevelamer-treated than for calcium-treated participants by a mean differential of $199 PMPM (mean, $5236 versus $5435; median, $4653 versus $4933), mainly because of lower inpatient costs for the sevelamer group (mean, $1461 versus $1644; median, $909 versus $1144). However, after phosphate binder costs were incorporated, costs trended lower for calcium-treated than for sevelamer-treated patients (differential -$81, 95% confidence interval -$321 to $157 PMPM, using average wholesale price; -$25, -$256 to $213 PMPM, using wholesale acquisition cost). CONCLUSIONS: Sevelamer reduced inpatient Medicare costs compared with calcium binders. However, when binder costs were added, overall PMPM costs favored calcium-treated over sevelamer-treated participants.

Healthcare utilisation and costs associated with adding montelukast to current therapy in patients with mild to moderate asthma and co-morbid allergic rhinitis: PRAACTICAL study.

OBJECTIVE: To evaluate the healthcare resource use and costs associated with adding montelukast to therapy in patients with mild to moderate persistent asthma and co-morbid seasonal allergic rhinitis whose asthma is inadequately controlled by their current asthma therapy. METHODS: A multicentre, pre-post retrospective cohort study was conducted in three European countries (Italy, Poland and Spain). Consecutive patients who were receiving inhaled corticosteroid therapy (monotherapy or combination therapy with long-acting beta(2)-adrenoceptor agonists) and who started concomitant treatment with montelukast between January 1999 and December 2002 were identified from clinical charts. Asthma/seasonal allergic rhinitis-related concomitant medications and asthma-related outpatient care, ED visits and hospitalisations for the periods 12 months before and 12 months after montelukast initiation were recorded from patient charts and combined with country-specific published unit costs (adjusted to 2004 values). The analysis was performed from a third-party-payer perspective and thus direct healthcare resource utilisation due to asthma/seasonal allergic rhinitis and associated costs for each country were estimated. RESULTS: A total of 98 physicians provided data for 696 asthmatic patients with seasonal allergic rhinitis (Italy: n = 158; Poland: n = 334; and Spain: n = 204). The mean age of patients was 32.7 years, 57.5% were female and patients had asthma that was considered either mild-persistent (54.5%) or moderate-persistent (45.5%) according to the Global Initiative for Asthma classifications. The introduction of montelukast (10 mg/day daily cost range euro0.8-1.68) was associated with increases in the total annual mean healthcare cost per patient of 11.9%, 60.4% and 5.5% for Italy, Poland and Spain, respectively. However, mean annual costs for asthma-related outpatient care, ED visits and hospitalisations dropped significantly in all three countries (Italy: from euro805.00 to euro281.60 [p < 0.01]; Poland: from euro127.10 to euro99.00 [p < 0.01]; and Spain: from euro463.40 to euro119.70 [p < 0.01]). CONCLUSIONS: The addition of montelukast to therapy in patients with mild to moderate asthma and concomitant seasonal allergic rhinitis whose asthma was inadequately controlled by current asthma therapy significantly reduced the use of concomitant asthma-allergy medications, ED visits, outpatient care visits and hospitalisation. The total direct healthcare cost obtained after the addition of montelukast increased only as a result of the montelukast treatment cost.

Comparative efficacy and cost of asthma care in children with asthma treated with fluticasone propionate and montelukast.

OBJECTIVE: To assess the comparative efficacy of fluticasone propionate (FP) and montelukast (MON), using administrative claims for pediatric asthma in a clinical setting. STUDY DESIGN: This retrospective observational study used the PharMetrics Integrated-Outcomes Database. Children age 4 to 17 years with an ICD-9-CM 493.xx for asthma, therapy with an inhaled corticosteroid in the 12 months before the index medications, and an index claim for FP or MON between January 2001 and December 2003 were studied. FP- and MON-treated children were propensity-matched based on health care utilization. Asthma-related parameters studied included treatment failure, hospitalizations, and total cost of care. RESULTS: The children treated with MON were more likely to experience treatment failure (odds ratio [OR] = 2.55; 95% confidence interval [CI] = 2.19 to 2.96) and to be admitted to the hospital for asthma-related care (OR = 1.99; 95% CI = 1.15 to 3.44) compared with those treated with FP. Furthermore, the children treated with MON incurred significantly higher asthma-related treatment costs compared with those treated with FP (parameter estimate = 0.418; P < .0001). CONCLUSIONS: In children with asthma, treatment with FP is associated with better outcomes and lower cost than treatment with MON.

Asthma and allergy medication use and costs among pediatric primary care patients on asthma controller therapy.

As observational studies in children initiating GINA-Step 3 therapies are scarce, we evaluated outcomes and costs in a primary care cohort. Two-yr retrospective cohort study included French children (age: 6-14) continuously followed in BKL-Thalès database who received > or =2 consecutive prescriptions for GINA-Step 3 therapy (=addition of montelukast or other controllers ('other'), such as increasing inhaled-corticosteroid dose (hICS), adding long-acting beta agonist (LABA), or ICS + LABA). After matching on gender and propensity score, medication use [rescue (short-acting beta agonists), acute (antibiotics (AB), oral corticosteroids (OCS)), allergy (antihistamines, nasal steroids) and other respiratory] was estimated via mean number of prescriptions and mean cost (per child/per month), and cost trends. During 12-month follow-up, children adding montelukast (n = 71) vs. 'other' (n = 213) had similar asthma rescue/acute and allergy medication use. Subgroup with asthma and allergic rhinitis (A + AR) adding montelukast used less OCS and AB (p = 0.014). Two-yr cost trends suggest stable asthma/allergy medication use in montelukast group (0.83 euro) compared with increase in 'other' (5.39 euro), which was driven by nasal steroid use [0.32 euro ('other') vs. -0.04 euro (montelukast), p = 0.0013]. In subgroup with A + AR decline in asthma/allergy medication use in montelukast group (-0.47 euro) vs. increase in 'other' (11.05 euro), p = 0.015, was driven by differences in AB and OCS (p = 0.04) and nasal steroid use (p = 0.001). Concomitant asthma/allergy medication use was similar in children adding montelukast or 'other' controllers (hICS, LABA, ICS + LABA), while children with allergic rhinitis on montelukast used less AB. Concomitant medication costs after addition of montelukast remained stable, while 'other' group experienced increase, especially in children with concomitant allergic rhinitis.

Asthma-related health care resource use among patients starting fluticasone or montelukast therapy.

STUDY OBJECTIVES: To compare patterns of asthma-related health care resource use among patients prescribed fluticasone or montelukast as singlecontroller therapy for asthma, and to confirm patterns previously observed in retrospective analyses examining outcomes among patients receiving fluticasone or montelukast for asthma. DESIGN: Retrospective cohort study. DATA SOURCE: Administrative claims data drawn from United States health insurers in 35 states, covering 17 million privately insured patients. PATIENTS; A total of 4758 patients aged 2-55 years with asthma who were prescribed either fluticasone or montelukast from July 1, 1998-June 30, 1999, were continuously enrolled for at least 24 months, had no evidence of controller therapy for 6 months before the start of drug therapy, and had no evidence of chronic obstructive pulmonary disease or other respiratory illness. MEASUREMENTS AND MAIN RESULTS: Patients were identified using an algorithm based on medical and pharmacy insurance claims. Patients were matched between groups based on a propensity score of clinical characteristics and age; this resulted in 1512 patients/treatment group. Asthma-related health care claims incurred for 12 months before and after the start of controller therapy were analyzed. After adjustment, the fluticasone-treated group had greater risk than the montelukast-treated group of requiring therapy with a short-acting beta-agonist in the follow-up period (relative risk 1.12, 95% confidence interval [CI] 1.03-1.20). Odds were similar across treatment groups for needing an emergency department visit and/or hospitalization (odds ratio 1.08, 95% CI 0.74-1.58) and for needing therapy with an oral corticosteroid (odds ratio 1.02, 95% CI 0.84-1.26). CONCLUSION: The start of therapy with either fluticasone or montelukast as a single-controller for asthma was associated with similar asthma-related health care resource use in this matched population.
