The cost-effectiveness of zuranolone versus selective serotonin reuptake inhibitors for the treatment of postpartum depression in the United States.

AIMS: The objective of this research is to evaluate the cost-effectiveness of zuranolone, the first oral treatment indicated for postpartum depression (PPD) in adults approved by the United States Food and Drug Administration. METHODS: Zuranolone and selective serotonin reuptake inhibitor (SSRI) trial-based efficacy was derived from an indirect treatment comparison. Long-term efficacy outcomes were based on a large longitudinal cohort study. Maternal health utility values were derived from trial-based, short-form 6-D responses. Other inputs were derived from literature and economic data from the US Bureau of Labor Statistics. We estimated costs (2023 US dollars) and quality-adjusted life-years (QALYs) for patients with PPD treated with zuranolone (14-day dosing) or SSRIs (chronic dosing). The indirect costs and QALYs of the children and partners were also estimated. RESULTS: The incremental cost-effectiveness ratio for zuranolone versus SSRIs was $94,741 per QALY gained over an 11-year time horizon. Maternal total direct medical costs averaged $84,318 in the zuranolone arm, compared to $86,365 in the SSRI arm. Zuranolone-treated adults averaged 6.178 QALYs compared to 6.116 QALYs for the SSRI arm. Costs and utilities for the child and partner were also included in the base case. Drug and administration costs for zuranolone averaged $15,902, compared to $30 for SSRIs over the studied time horizon. Results were sensitive to the model time horizon. LIMITATIONS: As head-to-head trials were not available to permit direct comparison, efficacy inputs were derived from an indirect treatment comparison which can be confounded by cross-trial differences. The data used are reflective of a general PPD population rather than marginalized individuals who may be at a greater risk for adverse PPD outcomes. The model likely excludes unmeasured effects for patient, child, and partner. CONCLUSIONS: This economic model's results suggest that zuranolone is a more cost-effective therapy compared to SSRIs for treating adults with PPD.

QUESTION: Is zuranolone cost-effective compared to selective serotonin-reuptake inhibitors for the treatment of postpartum depression (PPD) in adults in a United States (US) health care setting? FINDINGS: The model, which incorporated clinical trial data, long-term longitudinal cohort data, US Bureau of Labor Statistics data on compensation, and other peer-reviewed literature, projects that zuranolone is cost-effective compared to selective serotonin-reuptake inhibitors for the treatment of PPD at a willingness-to-pay threshold of $150,000 (USD).Meaning: For adults with PPD requiring pharmacological intervention, zuranolone may be a cost-effective treatment option with the potential to confer quality-of-life benefits for these patients and their families as well as economic benefits for society.

Comparative Efficacy of Targeted Systemic Therapies for Moderate-to-Severe Atopic Dermatitis without Topical Corticosteroids: An Updated Network Meta-analysis.

INTRODUCTION: The treatment landscape for moderate-to-severe atopic dermatitis (AD) continues to expand. This network meta-analysis (NMA) updates a previously conducted NMA to include data from the most recent phase 3 trials to assess the comparative efficacy of targeted systemic therapies without the addition of topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI) in adults with moderate-to-severe AD. METHODS: Data from recent phase 3 monotherapy trials of lebrikizumab, ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967), were included in the analyses, along with other eligible phase 3/4 randomized placebo-controlled trials for abrocitinib, baricitinib, dupilumab, tralokinumab, and upadacitinib identified through a systemic literature review in Silverberg et al. (Dermatol Ther (Heidelb) 12(5):1181-1196, 2022). The proportion of patients achieving Eczema Area and Severity Index (EASI) improvement ≥ 90% from baseline (EASI-90), EASI improvement ≥ 75% from baseline (EASI-75), ≥ 4-point improvement on Pruritus Numerical Rating Scale from baseline (ΔNRS ≥ 4), and Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) and reduction of ≥ 2 points from baseline (IGA 0/1) were evaluated using a Bayesian network meta-analysis. RESULTS: The updated NMA analyzed 13 unique placebo-controlled trials involving 7105 patients in 32 arms across 6 targeted therapies. Upadacitinib 30 mg was the most efficacious therapy across all endpoints at the primary timepoint (week 12 or 16) and at earlier timepoints, generally followed by abrocitinib 200 mg, upadacitinib 15 mg, dupilumab 300 mg, and lebrikizumab 250 mg or abrocitinib 100 mg. Baricitinib 2 mg and tralokinumab were generally ranked lower across outcomes. CONCLUSIONS: Many factors need to be considered for treatment selection for AD, especially as new treatments continue to emerge. After incorporating recent placebo-controlled phase 3 data of lebrikizumab, upadacitinib 30 mg, upadacitinib 15 mg, and abrocitinib 200 mg remain the most efficacious targeted systemic therapies over 12-16 weeks of therapy in AD. These updated findings can help healthcare providers when creating a patient's personalized treatment plan.

Indirect treatment comparison of oral versus injectable azacitidine as maintenance therapy for acute myeloid leukemia.

Aim: Evaluate the relative efficacy of oral versus injectable azacitidine (AZA) maintenance therapy in acute myeloid leukemia (AML) after complete remission. Materials & methods: Systematic literature review identified QUAZAR AML-001, HOVON 97 AML, UK NCRI AML16 and QoLESS-AZA-AMLE (sensitivity analysis) trials. Network meta-analysis and matching-adjusted indirect comparisons assessed survival outcomes. Results: In the network meta-analysis, combining the HOVON 97 and UK NCRI trials, oral AZA (QUAZAR) was associated with significantly improved overall survival (OS) versus injectable AZA (hazard ratio: 0.744; 95% credible interval: 0.557-0.998). After matching-adjusted indirect comparisons, to address differences in patient characteristics across trials, OS improvements were maintained with oral versus injectable AZA (hazard ratio: 0.753; credible interval: 0.563-0.998). Conclusion: In AML, maintenance therapy with oral AZA was associated with improved OS versus injectable AZA.

Older people with acute myeloid leukemia (AML) may have remission with or without blood count recovery, after first-line chemotherapy; however, remission is short lived and overall survival is limited (7­12 months). Ongoing treatment (maintenance therapy) after response to initial chemotherapy may prolong remission. Maintenance therapy with azacitidine (AZA) given by injection beneath the skin (subcutaneous) or into a vein (intravenous) can extend disease-free survival compared with no further treatment and best supportive care. However, treatment with intravenous AZA may only extend overall survival in certain patients. ONUREG^® is a novel formulation of AZA that can be taken by mouth (orally), remains in the body for longer periods and has the potential for significant clinical benefits compared with intravenous AZA. Presently, there are no studies directly comparing outcomes of maintenance therapy with oral and injectable AZA in older people with AML. In this analysis, we used an indirect treatment comparison method including four clinical trials to explore the survival benefit associated with ONUREG and injectable AZA when used as maintenance therapies after response to initial chemotherapy in older people with AML. Findings showed ONUREG significantly improved overall survival compared with injectable AZA, with an almost 26% reduction in the risk of death. These results suggest that maintenance therapy with ONUREG significantly improves overall survival compared with injectable AZA in older people with AML who may have remission with or without blood count recovery, after first-line chemotherapy.

Comparative Efficacy of Targeted Systemic Therapies for Moderate to Severe Atopic Dermatitis without Topical Corticosteroids: Systematic Review and Network Meta-analysis.

INTRODUCTION: The comparative efficacy of targeted systemic therapies for moderate to severe atopic dermatitis (AD) has not been systematically assessed using recent phase 3 data. This network meta-analysis assesses the comparative efficacy of targeted systemic therapies without the addition of topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI) in adults with moderate to severe AD. METHODS: The systematic literature review searched through 17 May 2021 for phase 3/4 trials with upadacitinib, interleukin-4 (IL-4), interleukin-13 (IL-13), or JAK inhibitors compared with placebo or active intervention for adults and adolescents with moderate to severe AD with inadequate response to TCS/TCI or for whom TCS/TCI was medically inadvisable, without restrictions on year or region. Researchers assessed data using PRISMA guidelines. The proportion of patients achieving trial co-primary endpoints [Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) and reduction of ≥ 2 points from baseline; proportion of patients achieving Eczema Area and Severity Index (EASI) improvement ≥ 75% from baseline (EASI-75)]; EASI improvement ≥ 90% from baseline (EASI-90); and ≥ 4-point improvement on Pruritus Numerical Rating Scale from baseline (ΔNRS ≥ 4) were evaluated using Bayesian network meta-analysis. RESULTS: Of 3415 initially identified records, network meta-analysis (NMA) ultimately included 6 records representing 9 unique studies. Two upadacitinib trials were also included. Eleven clinical trials including 6254 patients were analyzed. Upadacitinib 30 mg daily was the most efficacious therapy across all endpoints at the primary endpoint (week 12 or 16) and at earlier timepoints, followed by upadacitinib 15 mg daily and abrocitinib 200 mg daily. DISCUSSION: Many factors need to be considered for treatment selection for AD. These findings can help healthcare providers when personalizing a patient's treatment. CONCLUSION: Upadacitinib 30 mg daily, upadacitinib 15 mg daily, and abrocitinib 200 mg daily may be the most efficacious targeted systemic therapies over 12-16 weeks of therapy in AD.

Cost-Effectiveness of Brexanolone Versus Selective Serotonin Reuptake Inhibitors for the Treatment of Postpartum Depression in the United States.

BACKGROUND: Brexanolone injection (BRX) was approved by the FDA in 2019 for the treatment of adult patients with postpartum depression (PPD), but its cost-effectiveness has not yet been evaluated. OBJECTIVE: To estimate the cost-effectiveness of BRX compared with treatment with selective serotonin reuptake inhibitors (SSRIs) for PPD. METHODS: We projected costs (2018 U.S. dollars) and health (quality-adjusted life-years [QALYs]) for mothers treated with BRX or SSRIs and their children. A health state transition model projected clinical and economic outcomes for mothers based on the Edinburgh Postnatal Depression Scale, from a U.S. payer perspective. The modeled population consisted of adult patients with moderate to severe PPD, similar to BRX clinical trial patients. Short-term efficacy for BRX and SSRIs came from an indirect treatment comparison. Long-term efficacy outcomes over 4 weeks, 11 years (base case), and 18 years were based on results from an 18-year longitudinal study. Maternal health utility values came from analysis of trial-based short-form 6D responses. Other inputs were derived from the literature. RESULTS: The incremental cost-effectiveness ratio for BRX versus SSRIs was $106,662 per QALY gained over an 11-year time horizon. Drug and administration costs for BRX averaged $38,501, compared with $25 for SSRIs over the studied time horizon. Maternal total direct medical costs averaged $65,908 in the BRX arm, compared with $73,653 in the SSRI arm. BRX-treated women averaged 6.230 QALYs compared with 5.979 QALYs for the SSRI arm. Adding partner costs and utilities in a sensitivity analysis further favored BRX. Results were sensitive to the severity of PPD at baseline and the model time horizon. Probabilistic sensitivity analyses indicated that BRX was cost-effective at the $150,000-per-QALY threshold with 58% probability. CONCLUSIONS: Analysis using a state transition model showed BRX to be a cost-effective therapy compared with SSRIs for treating women with PPD.

Cost-effectiveness model for a hypothetical monotherapy vs standard of care in adult patients with treatment-resistant depression.

BACKGROUND: Patients with treatment-resistant major depressive disorder (TRD) have limited treatment options. We developed an early stage cost-effectiveness model of TRD to explore the potential value of a hypothetical monotherapy relative to the standard of care (SOC). The relative impacts of the monotherapy's three differentiating features over SOC are explored: efficacy advantage, tolerability advantage, and price premium. METHODS: We adapted an existing economic model of TRD to evaluate the cost-effectiveness of a hypothetical monotherapy for TRD with a 25% efficacy advantage, a 10% tolerability advantage, and a 50% price premium over SOC (selective serotonin reuptake inhibitor plus atypical antipsychotics [SSRI + AAP]). The model is a hybrid of a decision tree that captures patients' outcomes after an 8-week acute treatment phase and a Markov model that simulates patients' depression course through a 10-month maintenance phase. Sensitivity (deterministic and probabilistic) and scenario analyses were conducted to characterize the relative impacts of the monotherapy's three differentiating features over SOC. RESULTS: Over the 12-month time horizon, the hypothetical monotherapy is shown to dominate SOC; it generates lower costs and higher quality-adjusted life years in comparison to SSRI + AAP. Sensitivity and scenario analyses showed that this dominance depends largely on the monotherapy's efficacy and tolerability advantages over SOC. Specifically, a monotherapy with ≥ 12% efficacy or ≥70% tolerability advantage (and a 50% price premium) will always be superior to SSRI + AAP. Between these two extremes, most profiles, nonetheless, generate incremental cost-utility ratios for the monotherapy, which fall below common payer willingness-to-pay thresholds. CONCLUSION: Our adaptation of an existing economic model of TRD provides a flexible platform for researchers to evaluate the efficacy/tolerability improvements required for a successful new TRD product and for decision-makers to assess the cost-effectiveness impact of uncertainties inherent in early stage product development in TRD.

Cost-effectiveness of elagolix versus leuprolide acetate for treating moderate-to-severe endometriosis pain in the USA.

AIM: To assess the cost-effectiveness of elagolix versus leuprolide acetate in women with moderate to severe endometriosis pain. METHODS: A Markov model was developed. The efficacy of leuprolide acetate was derived from statistical prediction models using elagolix trial data. Model inputs were extracted from Phase III clinical trials and published literature. RESULTS: Compared with leuprolide acetate, elagolix generated positive net monetary benefit (NMB) assuming a payer's willingness-to-pay threshold of US$100,000 per quality-adjusted life year over a 1-year time horizon: US$5660 for elagolix 150 mg and US$6443 for elagolix 200 mg. The 2-year NMBs were also positive. CONCLUSION: Elagolix was cost effective versus leuprolide acetate in the management of moderate to severe endometriosis pain over 1- and 2-year time horizons. Results were robust in sensitivity analyses.

Risk of Developing Comorbidities Among Women with Endometriosis: A Retrospective Matched Cohort Study.

BACKGROUND: Endometriosis has been associated with higher rates of various chronic conditions, but its epidemiological data are fragmented and dated. We sought to compare the incidence of developing commonly occurring comorbidities among patients with and without endometriosis in a large, contemporary patient cohort that reflects real-world clinical practice. MATERIALS AND METHODS: A cohort of women aged 18-49 with incident endometriosis was extracted from the 2006-2015 de-identified Clinformatics® DataMart commercial insurance claims database (OptumInsight, Eden Prairie, MN). Endometriosis was identified by International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code 617.x on ≥1 inpatient or emergency department claim or ≥2 outpatient claims. Nonendometriosis control patients were exactly matched 4:1 to cases based on state, insurance plan type, and age (±1 year). Based on a literature review and expert consultation, 22 comorbidities were identified for analysis. The risk of developing a comorbidity post-index date was analyzed with stratified Cox proportional hazards models. RESULTS: There were 26,961 cases and 107,844 controls. Mean age was 36 years. The adjusted risk of developing a comorbid condition among endometriosis cases was statistically significantly higher than the matched controls for all 22 comorbidities (p ≤ 0.001) and was at least twice as large for nine comorbidities (infertility/subfertility, ovarian cyst, uterine fibroids, pelvic inflammatory disorder, interstitial cystitis, irritable bowel syndrome, constipation/dyschezia, ovarian cancer, and endometrial cancer). CONCLUSION: The incidence of developing many comorbidities was significantly higher among endometriosis patients compared with matched women without endometriosis. Additional research is needed to establish the implications for healthcare resource use.

Changes in Healthcare Spending After Diagnosis of Comorbidities Among Endometriosis Patients: A Difference-in-Differences Analysis.

INTRODUCTION: We sought to characterize changes in healthcare spending associated with the onset of 22 endometriosis-related comorbidities. METHODS: Women aged 18-49 years with endometriosis (N = 180,278) were extracted from 2006-2015 de-identified Clinformatics® DataMart claims data. For 22 comorbidities, comorbidity patients were identified on the basis of having a first comorbidity diagnosis after their initial endometriosis diagnosis. Controls were identified on the basis of having no comorbidity diagnosis and were matched 1:1 to comorbidity patients on demographics and baseline spending. Total medical and pharmacy spending was measured during 12 months before and after each patient's index date (first comorbidity diagnosis for comorbidity patients, and equal number of days after earliest endometriosis claim for controls). Pre-post spending differences were compared using difference-in-differences linear regression. Total and comorbidity-related cumulative spending per patient for all endometriosis patients were calculated annually for the 5 years following endometriosis diagnosis. RESULTS: The number of endometriosis patients with each comorbidity varied between 121 for endometrial cancer and 16,177 for fatigue. Healthcare spending increased significantly with the onset of eight comorbidities: breast cancer, ovarian cancer, pregnancy complications, systemic lupus erythematosus/rheumatoid arthritis/Sjogren's/multiple sclerosis, infertility, uterine fibroids, ovarian cyst, and headache [p < 0.001 except for headache (p = 0.045)]. Spending decreased significantly for fatigue, cystitis/UTI, and eczema [p < 0.001 except for fatigue (p = 0.048)] and was not statistically different for the other 11 comorbidities. Difference-in-differences estimates were significantly higher for comorbidity patients for all comorbidities except eczema (p ≤ 0.003). Mean 5-year total cumulative spending was $58,191 per endometriosis patient, of which between 11% and 23% was attributable to comorbidity-related medical claims. CONCLUSION: For all but one of the 22 comorbidities associated with endometriosis, comorbidity onset was associated with a relative increase in total healthcare spending. FUNDING: AbbVie Inc.

Effects of non-medical switching on outcomes among patients prescribed tumor necrosis factor inhibitors.

OBJECTIVE: To evaluate health care use and outcomes among patients who experienced a non-medical switch of their prescribed anti-tumor-necrosis-factor biological agent (anti-TNF) for cost containment reasons. METHODS: Retrospective evaluation of Humedica electronic health records of patients ≥18 years old with anti-TNF treatment for immune conditions. Using natural language processing, stable patients who experienced a non-medical switch (for cost reasons) of their anti-TNF between 2007 and 2013 were identified (NMS cohort, n = 158) and matched to patients who did not (control cohort, n = 4804). Rates of office visits, emergency department visits, and hospitalizations at 30, 90, and 365 days following were evaluated. Medication-related adverse events, defined as subsequent medication change due to a side effect and/or efficacy-related reason were also compared. RESULTS: Adjusted rates of office visits were higher among the NMS cohort than the control cohort at 30 (46.4% vs. 31.7%, p < .001), 90 (71.0% vs. 57.0%, p < .001), and 365 days (87.8% vs. 76.8%, p < .001). Rates of emergency department use and hospitalization were comparable between cohorts. The NMS cohort had higher adjusted rates of medication-related adverse consequences (both increased side effects and diminished efficacy) than the control cohort at 30 (13.8% vs. 4.0%, p = .003), 90 (31.6% vs 9.6%, p < .001), and 365 days (54.7% vs. 20.3%, p < .001). Compared with controls, the NMS cohort had higher adjusted rates of subsequent medication change within 1 year (27.82% vs. 13.9%, p = .001). CONCLUSION: Non-medical switching among patients prescribed anti-TNFs was associated with increased health care use, medication-related side effects, and reports of diminished efficacy.

The impact of persistence with mirabegron usage vs switching to onabotulinumtoxinA on healthcare costs and resource utilization in patients with overactive bladder in the United States.

AIMS: To compare healthcare costs and resource utilization in patients with overactive bladder (OAB) in the US who switch from mirabegron to onabotulinumtoxinA (onabotA) with those who persist on mirabegron. MATERIALS AND METHODS: A retrospective observational claims analysis of the OptumHealth Administrative Claims database conducted between April 1, 2012 and September 30, 2015 used medical and pharmacy claims to identify patients with at least one OAB diagnosis who switched from mirabegron to onabotA (onabotA group) or persisted on mirabegron for at least 180 days (mirabegron persisters). Propensity score weighting was used to balance baseline characteristics that were associated with increased healthcare expenditures across treatment groups. Multivariate analyses assessed the impact of switching and persistence on all-cause and OAB-related healthcare costs and resource utilization in the year following each patient's index date. RESULTS: In total, 449 patients were included in this study: 54 patients were included in the onabotA group, and 395 patients were included in the mirabegron persister group. Compared with the mirabegron persister patients, the onabotA patients observed significantly higher OAB-related total costs ($5,504 vs $1,772, p < .001), OAB-related medical costs ($5,033 vs $351, p < .001), sacral neuromodulation costs ($865 vs $60, p = .017), and outpatient costs ($17,385 vs $9,035, p = .009), and more OAB-related medical visits (6.0 vs 1.9, p < .001). OnabotA patients had lower OAB-related prescription costs ($470 vs $1,421, p < .001) and fewer OAB-related pharmacy claims (1.6 vs 5.0, p <.001). There were no significant differences in all-cause total medical or prescription costs. LIMITATIONS: This study was a retrospective analysis using claims data that only included patients with commercial health coverage or Medicare supplemental coverage. Accuracy of the diagnosis codes and the generalizability of the results to other OAB populations are limited. The study was not designed to determine the impact of OAB treatments on the economic outcomes examined. CONCLUSIONS: OAB patients who persisted on mirabegron treatment for at least 180 days had lower OAB-related healthcare costs and resource utilization compared with those who switched to onabotA.

Economic evaluation of ombitasvir/paritaprevir/ritonavir and dasabuvir for the treatment of chronic genotype 1 hepatitis c virus infection.

OBJECTIVES: To estimate clinical outcomes and cost-effectiveness of ombitasvir/paritaprevir/ritonavir and dasabuvir ± ribavirin (OMB/PTV/r + DSV ± RBV) compared with treatment regimens including pegylated interferon (PegIFN) for patients with chronic genotype 1 hepatitis C virus (HCV) infection. METHODS: An Excel spreadsheet Markov model tracking progression through stages of liver disease was developed. Costs and patient utilities for liver disease stages were taken from published studies. Rates of disease progression were based on studies of untreated HCV infection and long-term follow-up of those achieving sustained virologic response (SVR) after drug treatment. Impact of OMB/PTV/r + DSV ± RBV and other drug regimens on progression was estimated through SVR rates from clinical trials. Analyses were performed for treatment-naive and treatment-experienced patients. Impact of alternative scenarios and input parameter uncertainty on the results were tested. RESULTS: For genotype 1 treatment-naive HCV patients, for OMB/PTV/r + DSV ± RBV, PegIFN + ribavirin (PegIFN/RBV), sofosbuvir + PegIFN/RBV, telaprevir + PegIFN/RBV, boceprevir + PegIFN/RBV, lifetime risk of decompensated liver disease was 5.6%, 18.9%, 7.4%, 11.7%, and 14.9%; hepatocellular carcinoma was 5.4%, 9.2%, 5.7%, 7.0%, and 7.4%; and death from liver disease was 8.7%, 22.2%, 10.4%, 14.8%, and 17.6%, respectively. Estimates of the cost-effectiveness of OMB/PTV/r + DSV ± RBV for treatment-naive and treatment-experienced patients indicated that it dominated all other regimens except PegIFN/RBV. Compared with PegIFN/RBV, the incremental cost-effectiveness ratios were £13,864 and £10,258 per quality-adjusted life-year (QALY) for treatment-naive and treatment-experienced patients, respectively. The results were similar for alternative scenarios and uncertainty analyses. LIMITATIONS: A mixed-treatment comparison for SVR rates for the different treatment regimens was not feasible, because many regimens did not have comparator arms; instead SVR rates were based on those from recent trials. CONCLUSIONS: OMB/PTV/r + DSV ± RBV is a cost-effective oral treatment regimen for chronic genotype 1 HCV infection compared with standard treatment regimens and is estimated to reduce the lifetime risks of advanced liver disease.

Healthcare costs and utilization for privately insured patients treated for non-infectious uveitis in the USA.

BACKGROUND: The purpose of this study was to describe comorbidities, healthcare costs, and resource utilization among patients with chronic non-infectious uveitis initiating corticosteroid, immunosuppressants, or biologics.In this retrospective cohort study, patients with a non-infectious uveitis diagnosis and continuous insurance coverage during a 6-month baseline were selected from a privately insured claims database with 80.7 million enrollees. Index dates were defined as the first prescription/administration of a corticosteroid, immunosuppressant, or biologic between 2003 and 2009. Comorbidities, healthcare costs, and utilization were analyzed in a per-member-per-month (PMPM) framework to account for varying between-patient treatment periods, defined as continuous medication use within the same class. Wilcoxon rank-sum and chi-square tests were used for comparisons of costs and categorical outcomes. RESULTS: Patients on corticosteroids (N = 4,568), immunosuppressants (N = 5,466), and biologics (N = 1,694) formed the study population. Baseline PMPM inpatient admission rates were 0.029 for patients on corticosteroids, 0.044 for patients on immunosuppressants, and 0.045 for patients on biologics (p < 0.001 immunosuppressants or biologics versus corticosteroids); during treatment, PMPM inpatient admissions increased to 0.044 and 0.048 for patients taking corticosteroids and immunosuppressants, respectively, but decreased to 0.024 for patients taking biologics (p < 0.001 versus corticosteroids and p = 0.003 versus immunosuppressants). Baseline average PMPM costs for patients taking corticosteroids, immunosuppressants, and biologics were US$935, US$1,738, and US$1,439 (p < 0.001 between groups), while on-treatment PMPM costs excluding drug costs increased to US$1,129 for patients taking corticosteroids but lowered to US$1,592 for patients taking immunosuppressants, and US$918 for patients taking biologics (p < 0.001 versus corticosteroids or immunosuppressants). CONCLUSIONS: There is significant economic burden associated with existing treatments of uveitis. Corticosteroids may be overused as a treatment for uveitis.

Effects of care management and telehealth: a longitudinal analysis using medicare data.

OBJECTIVES: To evaluate mortality and healthcare utilization effects of an intervention that combined care management and telehealth, targeting individuals with congestive heart failure, chronic obstructive pulmonary disease, or diabetes mellitus. DESIGN: Retrospective matched cohort study. SETTING: Northwest United States. PARTICIPANTS: High-cost Medicare fee-for-service beneficiaries (N = 1,767) enrolled in two Centers for Medicare and Medicaid Services demonstration participating clinics and a propensity-score matched control group. INTERVENTION: The Health Buddy Program, which integrates a content-driven telehealth system with care management. MEASUREMENTS: Mortality, inpatient admissions, hospital days, and emergency department (ED) visits during the 2-year study period were measured. Cox-proportional hazard models and negative binomial regression models were used to assess the relationship between the intervention and survival and utilization, controlling for demographic and health characteristics that were statistically different between groups after matching. RESULTS: At 2 years, participants offered the Health Buddy Program had 15% lower risk-adjusted all-cause mortality (hazard ratio (HR) = 0.85, 95% confidence interval (CI) = 0.74-0.98; P = .03) and had reductions in the number of quarterly inpatient admissions from baseline to the study period that were 18% greater than those of matched controls during this same time period (-0.035 vs -0.003; difference-in-differences = -0.032, 95% CI = -0.054 to -0.010, P = .005). No relationship was found between the Health Buddy Program and ED use or number of hospital days for participants who were hospitalized. The Health Buddy Program was most strongly associated with fewer admissions for individuals with chronic obstructive pulmonary disease and mortality for those with congestive heart failure. CONCLUSION: Care management coupled with content-driven telehealth technology has potential to improve health outcomes in high-cost Medicare beneficiaries.

Costs of Parkinson's disease in a privately insured population.

BACKGROUND: This is the first analysis to estimate the costs of commercially insured patients with Parkinson's disease (PD) in the USA. Prior analyses of PD have not examined costs in patients aged under 65 years, a majority of whom are in the workforce. OBJECTIVE: Our objective was to estimate direct and indirect costs associated with PD in patients under the age of 65 years who are newly diagnosed or have evidence of advanced PD. METHODS: PD patients were selected from a commercially insured claims database (N > 12,000,000; 1999-2009); workloss data were available for a sub-sample of enrollees. Newly diagnosed patients with evidence of similar disorders were excluded. Patients with evidence of advanced PD disease, including ambulatory assistance device users (PDAAD) and institutionalized (PDINST) patients, as well as newly diagnosed PD patients, were analyzed. Each PD cohort was age-, gender- and region-matched to controls without PD. Direct (i.e. insurer payments to providers) and indirect (i.e. workloss) costs were reported in $US, year 2010 values, and were descriptively compared using Wilcoxon rank sum tests. RESULTS: Patients had excess mean direct PD-related costs of $US4,072 (p < 0.001; N = 781) in the year after diagnosis. The PDAAD cohort (N = 214) had excess direct PD-related costs of $US26,467 (p < 0.001) and the PDINST cohort (N = 156) had excess direct PD-related costs of $US37,410 (p < 0.001) in the year after entering these states. Outpatient care was the most expensive cost source for newly diagnosed patients, while inpatient care was the most expensive for PDAAD and PDINST patients. Excess indirect costs were $US3,311 (p < 0.05; N = 173) in the year after initial diagnosis. CONCLUSIONS: Direct costs for newly diagnosed PD patients exceeded costs for controls without PD, and increased with PD progression. Direct costs were approximately 6-7 times higher in patients with advanced PD than in matched controls. Indirect costs represented 45 % of total excess costs for newly diagnosed PD patients.

An economic model of Parkinson's disease: implications for slowing progression in the United States.

Multiple studies describe progression, dementia rates, direct and indirect costs, and health utility by Hoehn and Yahr (H&Y) stage, but research has not incorporated these data into a model to evaluate possible economic consequences of slowing progression. This study aimed to model the course of Parkinson's disease (PD) and describe the economic consequences of slower rates of progression. A Markov model was developed to show the net monetary benefits of slower rates of progression. Four scenarios assuming hypothetical slower rates of progression were compared to a base case scenario. A systematic literature review identified published longitudinal H&Y progression rates. Direct and indirect excess costs (i.e., healthcare costs beyond what similar patients without PD would incur), mortality rates, dementia rates, and health utility were derived from the literature. Ten publications (N = 3,318) were used to model longitudinal H&Y progression. Base case results indicate average excess direct costs of $303,754, life-years of 12.8 years and quality-adjusted life-years of 6.96. A scenario where PD progressed 20% slower than the base case resulted in net monetary benefits of $60,657 ($75,891 including lost income) per patient. The net monetary benefit comes from a $37,927 decrease in direct medical costs, 0.45 increase in quality-adjusted life-years, and $15,235 decrease in lost income. The scenario where PD progression was arrested resulted in net monetary benefits of $442,429 per patient. Reducing progression rates could produce significant economic benefit. This benefit is strongly dependent on the degree to which progression is slowed.

Physician response to financial incentives when choosing drugs to treat breast cancer.

This paper considers physician agency in choosing drugs to treat metastatic breast cancer, a clinical setting in which patients have few protections from physicians' rent seeking. Physicians have explicit financial incentives attached to each potential drug treatment, with profit margins ranging more than a hundred fold. SEER-Medicare claims and Medispan pricing data were formed into a panel of 4,503 patients who were diagnosed with metastatic breast cancer and treated with anti-cancer drugs from 1992 to 2002. We analyzed the effects of product attributes, including profit margin, randomized controlled trial citations, FDA label, generic status, and other covariates on therapy choice. Instruments and drug fixed effects were used to control for omitted variables and possible measurement error associated with margin. We find that increasing physician margin by 10% yields between an 11 and 177% increase in the likelihood of drug choice on average across drugs. Physicians were more likely to use drugs with which they had experience, had more citations, and were FDA-approved to treat breast cancer. Oncologists are susceptible to financial incentives when choosing drugs, though other factors play a large role in their choice of drug.
