Locoregional therapy patterns and healthcare economic burden of patients with hepatocellular carcinoma in the USA.

AIM: To examine the locoregional therapy (LRT) patterns and the healthcare economic burden of patients with hepatocellular carcinoma (HCC) in the USA. PATIENTS & METHODS: Patients with newly diagnosed HCC were identified from the MarketScan® databases (1 July 2015-31 May 2018). The LRTs received and all-cause and HCC-related healthcare costs were measured. RESULTS: Among 2101 patients with HCC, most received embolization therapy as their first LRT treatment (57.8%, n = 1215); 17.1% (n = 360) received ablative therapy and 8.7% (n = 182) radiation therapy; 16.4% (n = 344) received multiple LRTs. After patients received their first LRT treatment, total all-cause healthcare costs averaged $20,316 per patient per month; 70.7% ($14,359) were HCC related. CONCLUSION: Among newly diagnosed HCC patients treated with LRT in the USA, the economic burden is high.

Atomistic Insights into Aluminum Doping Effect on Surface Roughness of Deposited Ultra-Thin Silver Films.

Ultra-thin and continuous metallic silver films are attracting growing interest due to the applications in flexible transparent conducting electrodes. The surface morphology and structure of silver film are very important for its electrical resistivity and optical loss. Therefore, roughness control is essential for the production of ultra-thin metallic electrode film. We have investigated the effect of aluminum doping on the improvement of surface morphology of ultra-thin silver films using molecular dynamics simulations. Al-doped silver films showed smaller surface roughness than pure silver films at various substrate temperatures. When the temperature of the substrate was 600 K, the roughness of Al-doped silver film first decreased, and then increased with the increase of the incident velocity of silver atoms. Silver atoms were more likely to agglomerate on the surface of the substrate after adding aluminum atoms, as aluminum dopants promoted the immobilization of silver atoms on SiO2 substrate due to the anchoring effect. The smoother surface could be attributable to the reduced mean free path of silver due to the cage effect by the aluminum dopant.

Frequency of hospital readmissions for venous thromboembolism and associated hospital costs and length of stay among acute medically ill patients in the US.

Objectives: This study evaluated the frequency of hospital readmissions for venous thromboembolism (VTE) and the associated costs and length of stay (LOS) among acute medically ill patients in the US using a real-world claims database analysis. Methods: Patients (≥40 years of age) at risk of VTE due to hospitalization for acute medical illnesses, based on primary hospital discharge diagnosis codes, were identified from the MarketScan databases between July 1, 2011 and March 31, 2015. Patients were required to have continuous insurance enrollment in the 6 months prior to initial (index) hospitalizations (baseline period) and in the 6 months after hospital discharge (follow-up period). The proportions of patients with VTE-related (diagnosis at any position) and VTE as primary diagnosis hospital readmissions during the follow-up period were evaluated. The associated costs and LOS for such readmissions were also determined, as well as time to VTE-related readmissions. Results: Of the study population (n = 12,785; mean age = 68.3 years), most were hospitalized primarily for infectious diseases (35.2%), followed by respiratory diseases (27.9%), cancer (15.7%), heart failure (11.8%), ischemic stroke (8.1%), and rheumatic diseases (1.4%). Of the overall study population, 2.1% (n = 268) had a VTE-related hospital readmission in the 6 months following discharge of their index hospitalization, of which 36.6% (n = 98) were for a primary diagnosis of VTE. Approximately 25.4% of the VTE-related hospital readmissions occurred within the first 30 days of discharge and 58.2% within 90 days. The mean cost for a hospital readmission with a primary diagnosis of VTE was $18,681 (mean LOS = 5.0 days); for readmissions with a primary diagnosis of DVT and PE, mean costs were $14,719 and $23,305, respectively. Conclusions: Among this study population of patients hospitalized for acute medical illnesses, some experienced a VTE event requiring re-hospitalization, with 25% occurring within the first 30 days after hospital discharge.

Economic modeling to evaluate the impact of chronic myeloid leukemia therapy management on the oncology care model in the US.

Objective: To develop an economic model to evaluate changes in healthcare costs driven by restricting usage of branded tyrosine kinase inhibitors (TKIs) through substitution with generic imatinib among chronic myeloid leukemia (CML) patients in a typical Oncology Care Model (OCM) practice, and examine the impact on Performance-Based Payment (PBP) eligibility. Methods: An Excel-based economic model of an OCM practice with 1,000 cancer patients during a 6-month episode of care was developed. Cancer types and proportions of patients treated in the practice were estimated from an OCM report. All-cause healthcare costs were obtained from published literature. It was assumed that if a practice restricts usage of branded TKIs for newly-diagnosed CML patients, 80% of the market share of branded imatinib and 50% of the market shares of 2nd-gen TKIs would shift to generic imatinib. Among established TKI-treated patients, it was assumed that 80% of the market share of branded imatinib and no patients treated with 2nd-gen TKIs would shift to the generic. Results: Four CML patients were estimated for a 1,000-cancer patient OCM practice with a total baseline healthcare cost of $51,345,812 during a 6-month episode. If the practice restricts usage of branded TKIs, the shift from 2nd-gen TKIs to generic imatinib would reduce costs by $12,970, while shifting from branded to generic imatinib lowers costs by $25,250 during a 6-month episode. Minimum reductions of $3,013,832 in a one-sided risk model and $2,372,010 in a two-sided risk model are required for PBP eligibility; the shift from 2nd-gen TKIs to generic imatinib would account for 0.4% and 0.5% of the savings required for a PBP, respectively. Conclusions: This analysis indicates that the potential cost reduction associated with restricting branded TKI usage among CML patients in an OCM setting will represent only a small proportion of the cost reduction needed for PBP eligibility.

Reduced Imaging Radiation Exposure and Costs Associated with Anti-Tumor Necrosis Factor Therapy in Crohn's Disease.

BACKGROUND: Radiation exposure from diagnostic imaging may increase cancer risk of Crohn's disease (CD) patients, who are already at increased risk of certain cancers. AIM: To compare imaging radiation exposure and associated costs in CD patients during the year pre- and post-initiation of anti-tumor necrosis factor (anti-TNF) agents or corticosteroids. METHODS: Adults were identified from a large US claims database between 1/1/2005 and 12/31/2009 with ≥ 1 abdominal imaging scan and 12 months of enrollment before and after initiating therapy with anti-TNF or corticosteroids. Imaging utilization, radiation exposure, and healthcare costs pre- and post-initiation were examined. RESULTS: Anti-TNF-treated patients had significantly fewer imaging examinations the year prior to initiation than corticosteroid-treated patients. Cumulative radiation doses before initiation were significantly higher for corticosteroid patients compared to anti-TNF patients (22.3 vs. 17.7 millisieverts, P = 0.0083). After therapy initiation, anti-TNF-treated patients had significantly fewer imaging examinations (2.9 vs. 5.2, P < 0.0001) and less radiation exposure (7.4 vs. 15.4 millisieverts, P <0.0001) than corticosteroid-treated patients in the follow-up period. Reductions in imaging costs adjusted for 1000 patient-years after initiation of therapy were - $275,090 and - $121,960 (P = 0.0359) for anti-TNF versus corticosteroid patients, respectively. CONCLUSIONS: This analysis demonstrated that patients treated with anti-TNF agents have fewer imaging examinations, less radiation exposure, and lower healthcare costs associated with imaging than patients treated with corticosteroids. These benefits do not account for additional long-term benefits that may be gained from reduced radiation exposure.

Impact of earlier versus later monitoring on disease progression and healthcare costs among patients with chronic myeloid leukemia in the United States.

We evaluated the impact of molecular monitoring earlier as compared to later in the course of chronic myeloid leukemia (CML) on disease progression and healthcare costs in the real-world setting in the US. Patients with a diagnosis of CML were identified from the MarketScan claims databases (1 January 2006 to 30 June 2016). Multivariable regression analyses were used to control for differences in patient cohorts with earlier versus later monitoring. Of the 2730 CML patients in the study population, 60% (n = 1633) received earlier monitoring and 40% (n = 1097) received later monitoring only. After adjusting for differences in patient characteristics, patients with earlier monitoring had a lower likelihood of CML progression during the follow-up period (odds ratio: 0.72, confidence interval: 0.53-0.96; p = .03) and lower total healthcare costs ($6794 versus $9782 per-patient-per-month, p < .001) than patients with later monitoring. Patients who are monitored earlier in the course of CML may have better outcomes and lower total costs of care.

Venous Thromboembolism Prophylaxis and Risk in the Inpatient and Outpatient Continuum of Care Among Hospitalized Acutely Ill Patients in the US: A Retrospective Analysis.

INTRODUCTION: Venous thromboembolism (VTE) is a leading cause of preventable morbidity and mortality among hospitalized patients in the US. The objectives of this study were to examine VTE prophylaxis patterns and risk for VTE events during hospitalization and post-discharge among patients hospitalized for acute illnesses in the US. METHODS: Acutely ill hospitalized patients were identified from the MarketScan databases (January 1, 2012-June 30, 2015). Proportions of patients that received inpatient and/or outpatient VTE prophylaxis were determined. VTE rates were calculated for the overall study population and for each subpopulation with each acute illness type. Risk for VTE events after the index admission was determined by Kaplan-Meier analysis. RESULTS: Of the acutely ill patients (n = 17,895, mean age: 58.4 years), most were hospitalized for infectious diseases (40.6%), followed by respiratory diseases (31.0%), cancer (10.7%), heart failure (10.4%), ischemic stroke (6.4%), and rheumatic diseases (0.9%). Among the entire study population, 59.1% did not receive any VTE prophylaxis, and only 7.1% received both inpatient and outpatient prophylaxis. Among the overall study population, cumulative VTE rate, including during index admission and within 6 months post-discharge, was 4.6%. VTE risk in the inpatient and outpatient continuum of care remained elevated up to 30-40 days after hospital admission, with 60.1% of VTEs occurring within 40 days of hospital admission. CONCLUSION: In this retrospective analysis of nearly 18,000 patients hospitalized for acute illnesses, 59.1% did not receive any VTE prophylaxis and only 7.1% received VTE prophylaxis in both the inpatient and outpatient continuum of care, despite significant VTE risk extending from hospitalization into the post-discharge period.

Economic value of regular monitoring of response to treatment among US patients with chronic myeloid leukemia based on an economic model.

BACKGROUND: Regular molecular monitoring with reverse-transcription quantitative PCR (RT-qPCR) analysis of BCR-ABL1 transcripts is associated with reduced disease progression among patients with chronic myeloid leukemia (CML). Molecular monitoring assists in the timely detection of primary or secondary resistance to tyrosine kinase inhibitor (TKI) therapy and is a recommended practice by the National Comprehensive Cancer Network guidelines. An economic model was developed to estimate the potential impact of CML monitoring vs lack of monitoring on patient healthcare costs. METHODS: An Excel-based decision-analytic economic model was developed from a US payer perspective. The model was used to estimate the expected healthcare cost differences between regular molecular monitoring of CML patients and lack of monitoring. CML progression rates among patients with vs without monitoring, the annual cost of CML progression, the average number of monitoring tests per year, and the average cost per RT-qPCR monitoring test were incorporated into the model. Univariate and multivariable sensitivity analyses were conducted. RESULTS: Based on estimates in published literature, disease progression to the accelerated/blast phase occurs among 0.35% of patients with monitoring and 5.12% of patients without monitoring, and the annual cost of CML progression is $136,308 per patient year. The analysis found that total healthcare costs, including the costs associated with CML progression and RT-qPCR monitoring tests (three tests per year), were $1,142 for patients with monitoring and $6,982 for patients without monitoring (difference = $5,840). In a hypothetical cohort of 100 patients with CML, achieving a 100% monitoring rate was associated with a total cost-savings of $584,005 compared to a 0% monitoring rate. This cost-savings remained consistent under both univariate and multivariable sensitivity analyses. CONCLUSION: Regular CML monitoring was associated with improved outcomes among CML patients and, consequently, reduced healthcare costs.

Improving quality of care in oncology through healthcare payment reform.

OBJECTIVES: To provide an overview of alternative payment models (APMs) and describe how leading national organizations involved with oncology care and payment are linking quality improvement initiatives and payment reform. STUDY DESIGN: Literature review. METHODS: For this review, we summarized the literature on APMs and their goals of improving healthcare quality while jointly controlling the cost of care. We described the types of APMs that have been examined in the real-world setting, specifically in the area of oncology, and how they have affected the quality of oncology care. RESULTS: Currently, the following types of APMs are actively being explored by public- and private-sector insurers, specifically in oncology: accountable care organizations, bundled payments, clinical pathways, and patient-centered medical homes. To a great extent, the driving force behind implementing APMs tied to quality can be attributed to the initiatives of several leading national organizations, including the National Academy of Medicine, the American Society of Clinical Oncology, the National Committee for Quality Assurance, HHS, and CMS. Real-world evidence of APMs shows that progress is being made toward improving the quality of oncology care in the United States while simultaneously reducing costs. CONCLUSIONS: The effective pairing of quality initiatives with healthcare reimbursement structures will likely be key to the long-term success of such APMs.

Impact of Genetic Mutations and Health Plan Access to Therapies on Treatment Response and Drug Costs Related to Tyrosine Kinase Inhibitor Treatment Among Patients With Chronic Myelogenous Leukemia.

OBJECTIVES: This study assessed treatment responses and economic consequences of limiting access to the second-generation BCR-ABL1 tyrosine kinase inhibitors (2G-TKI), dasatinib and nilotinib, for treatment of chronic myelogenous leukemia, while taking into account frequencies of genetic mutations that exhibit different sensitivities to the 2G-TKIs. METHODS: Frequencies of BCR-ABL1 mutations and the impact of mutations on responses to 2G-TKIs were obtained from published literature and used as inputs in a decision analytics model. Complete hematologic response (CHR) and major cytogenetic response (MCyR) were estimated after 12 months of 2G-TKI treatment. Total annual 2G-TKI drug costs per CHR and MCyR were estimated and compared among 3 2G-TKI access scenarios: (1) open access to both 2G-TKIs; (2) access restricted to dasatinib (DASA-only); and (3) access restricted to nilotinib (NILO-only). RESULTS: Among a hypothetical cohort of 1000 2G-TKI-treated chronic myelogenous leukemia patients, the percentage of patients with CHR and MCyR were greatest for the open access plan (CHR: 93%, MCyR: 56%), followed by DASA-only (88%, 53%) and NILO-only (67%, 47%). Compared with the 2G-TKI costs per CHR in open access ($120,706/CHR), the costs were 5% higher ($126,753/CHR) in DASA-only and 41% higher ($169,990/CHR) in NILO-only. Likewise, compared with the 2G-TKI costs per MCyR in open access ($198,284/MCyR), the costs were 6% higher ($209,259/MCyR) in DASA-only and 22% higher ($241,515/MCyR) in NILO-only. CONCLUSION: Open access to both 2G-TKIs is associated with improved clinical and economic outcomes: greater treatment response rates (CHR and MCyR) and lower drug costs compared with restricted access to 2G-TKIs.

Occurrence of Chronic Pelvic Pain, Abnormal Uterine Bleeding, and Hysterectomy Post-procedure among Women Who Have Undergone Female Sterilization Procedures: A Retrospective Claims Analysis of Commercially Insured Women in the US.

STUDY OBJECTIVE: To evaluate the frequency of chronic pelvic pain (CPP), abnormal uterine bleeding (AUB), and hysterectomy after hysteroscopic sterilization (HS) or laparoscopic sterilization (LS) in the United States. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Commercially insured women. PATIENTS: Women (aged 18-49 years) with claims for HS or LS from January 1, 2010 to December 31, 2012 were identified from the MarketScan Commercial database. Women were required to have 6 months of continuous coverage before (baseline) and 24 months after (follow-up) the procedure date. Women with ≥1 diagnosis for a pain condition (pain in pelvis/lower abdomen, low back pain, chronic headache, fibromyalgia) and/or AUB (excessive/frequent menstruation, irregular menstrual cycle, metorrhagia) during baseline were identified with International Classification of Diseases, Ninth Revision, Clinical Modification codes. INTERVENTIONS: HS/LS. MEASUREMENTS AND MAIN RESULTS: Outcome measurements were proportions of women with CPP, AUB, and hysterectomy during follow-up. Among the study population 10 224 women underwent HS, whereas 8051 underwent LS. During baseline 23.3% and 26.9% of women with HS and LS, respectively, had a pre-existing pain diagnosis. Among both HS and LS study cohorts, greater proportions of women with a pre-existing pain condition versus those without had CPP in the 24 months afterward (HS cohort: 19.8% vs 9.3%, p < .001; LS cohort: 23.8% vs 11.4%, p < .001). During baseline 11.7% and 6.4% of women with HS and LS, respectively, had pre-existing AUB. Among cohorts, greater proportions of women with pre-existing AUB versus those without had AUB in the 24 months afterward (HS cohort: 21.2% vs 7.3%, p < .001; LS cohort: 15.9% vs 6.4%, p < .001). Among women who underwent HS and LS, pre-existing pain and AUB were associated with higher rates of hysterectomy postprocedure. Multivariable regression results showed similar direction of findings. CONCLUSION: Among women who underwent HS and LS, pre-existing pain conditions and AUB were associated with higher rates of CPP and AUB postprocedure, respectively, and both pre-existing conditions were associated with a greater frequency of subsequent hysterectomy.

Comparison of Health Care Utilization and Costs Between Patients with Perianal Fistulizing Crohn's Disease Treated with Biologics with or Without Previous Seton Placement.

BACKGROUND: Fistulas are a common and often debilitating complication of Crohn's disease (CD). Tumor necrosis factor inhibitors and/or seton drainage are effective treatment options. We compared health care utilization and costs for patients with perianal CD who had setons placed before treatment with biologics versus those who did not. METHODS: Patients with CD (≥18 yr) were identified from the Truven Health MarketScan Database by ICD-9 code 555.x (January 1, 2006-March 31, 2015); those with external fistulas were identified by ICD-9 codes 565.1. Biological treatment and seton procedures were identified with the National Drug Codes or Current Procedural Terminology codes. Patients were grouped into 2 cohorts: seton before biological (SBB) treatment or no seton before biological (NSBB) treatment. RESULTS: SBB (N = 326) and NSBB (N = 1519) groups were similar in baseline age, sex, use of immunosuppressants and steroids, and comorbidity score. Baseline prevalence of asthma and cardiovascular disease, and use of antibiotics and 5-aminosalicylic acid were significantly greater in the SBB group versus the NSBB group. Baseline number of all-cause and fistula-related hospitalizations were greater for the SBB group than in the NSBB group. However, during follow-up, the NSBB group required significantly more hospitalizations than the SBB group (all-cause: 0.41 versus 0.23; fistula related: 0.16 versus 0.07) and had significantly greater health care costs (all-cause: $9711 versus $5514; fistula related: $4156 versus $1900). Results were confirmed in multivariate regressions adjusting for baseline characteristics and prescription drug use. CONCLUSIONS: Patients who had the setons placed before treatment with biologics used fewer health care resources and incurred lower health care costs compared with those who did not have the procedure.

Evaluation of healthcare resource utilization and incremental economic burden of patients with chronic myeloid leukemia after disease progression to blast phase.

AIMS: To evaluate healthcare resource utilization and economic burden of patients with chronic myeloid leukemia (CML) progression to the blast phase. METHODS: Patients (≥ 18 years) with ≥1 inpatient or ≥2 outpatient CML diagnoses were identified from the MarketScan Commercial and Medicare databases (January 1, 2007-June 30, 2015). CML patients were grouped into two study cohorts, those with evidence of disease progression to the blast phase and those without. Patients were required to have continuous medical and prescription coverage during a 12-month baseline period, in which demographics and clinical characteristics were evaluated. All-cause healthcare resource utilization and costs were evaluated during the baseline period, and a variable follow-up period, lasting ≥1 day and up to 1 year. Generalized linear models (GLM) were used to compare the incremental costs of CML patients with vs without progression. RESULTS: Of the overall study population, 587 (7%) experienced disease progression and 7,504 (93%) did not. On the index date, of patients with progression, ∼ 31% were treated with allogeneic hematopoietic cell transplant and 69% with chemotherapy. During the baseline period, mean total healthcare costs, including costs for hospitalizations and outpatient costs, were significantly greater for CML patients with progression as compared to those without progression ($143,778 vs $53,143, p < .001). During the follow-up, mean total healthcare costs, costs for hospitalizations, and outpatient medical service costs were substantially greater for patients with progression as compared to those without progression; however, costs for outpatient prescriptions were less for patients who progressed. When patient characteristics were controlled for, mean incremental 1-year cost for CML patients with vs without progression was $270,925 (confidence interval = $235,290-$311,958, p < .001). CONCLUSIONS: The healthcare burden, in terms of healthcare resource utilization and costs, of patients with CML progression is substantial. Healthcare providers and payers should consider various strategies to minimize the rate of CML progression.

Lixisenatide reduces glycaemic variability in insulin-treated patients with type 2 diabetes.

Chronic hyperglycaemia and glucose variability are associated with the development of chronic diabetes-related complications. We conducted a pooled analysis of patient-level data from three 24-week, randomized, phase III clinical trials to evaluate the impact of lixisenatide (LIXI) on glycaemic variability (GV) vs placebo as add-on to basal insulin. The main outcome GV measures were standard deviation (s.d.), mean amplitude of glycaemic excursions (MAGE), mean absolute glucose (MAG) level, area under the curve for fasting glucose (AUC-F), and high (HBGI) and low blood glucose index (LBGI). The change in GV metrics over 24 weeks and relationships among baseline GV, patient characteristics and outcomes were assessed. Data were pooled from 1198 patients (665 LIXI, 533 placebo). Values for s.d., MAG level, MAGE, HBGI, and AUC-F significantly decreased with LIXI vs placebo, while LBGI values were unchanged. Higher baseline GV measures correlated with older age, longer type 2 diabetes duration, lower body mass index, higher baseline glycated/haemogobin, greater reduction in postprandial glucose (PPG) level, and higher rates of symptomatic hypoglycaemia. These data show that LIXI added to basal insulin significantly reduced GV and PPG excursions vs placebo, without increasing the risk of hypoglycaemia (LBGI).

Healthcare and economic burden of adverse events among patients with chronic myelogenous leukemia treated with BCR-ABL1 tyrosine kinase inhibitors.

OBJECTIVES: BCR-ABL1 tyrosine kinase inhibitors (TKIs) are established treatments for chronic myelogenous leukemia (CML); however, they are associated with infrequent, but clinically serious adverse events (AEs). The objective of this analysis was to assess healthcare resource utilization and costs associated with AEs, previously identified using the FDA Adverse Event Reporting System (FAERS) in another study, among TKI-treated patients. METHODS: Adult patients with ≥1 inpatient or ≥2 outpatient ICD-9-CM diagnosis codes for CML and ≥1 claim for a TKI treatment between January 1, 2006 and September 30, 2012 were identified from the Commercial and Medicare MarketScan databases. The first claim for a TKI was designated as the index event. Patients were required to have no TKI treatment during a 12-month baseline period. Healthcare resource utilization and costs associated with select AEs having the strongest association with TKI treatment (femoral arterial stenosis [FAS], peripheral arterial occlusive disease [PAOD], intermittent claudication, coronary artery stenosis [CAS], pericardial effusion, pleural effusion, malignant pleural effusion, conjunctival hemorrhage) were evaluated during a 12-month follow-up period. RESULTS: The study sample included 2,005 CML patients receiving TKI therapy (mean age = 56 years; 56% male). Among all evaluated AEs, the highest mean inpatient healthcare costs were observed for FAS ($16,800 per patient) and PAOD ($14,263 per patient), which had total mean medical costs (inpatient + outpatient) of $17,015 and $15,154 per patient, respectively. Mean outpatient healthcare costs were highest for CAS ($1,861 per patient), followed by intermittent claudication ($947 per patient), PAOD ($891 per patient), and pleural effusion ($890 per patient). Total mean medical costs for fluid retention-related AEs, including pericardial effusion and pleural effusion, were $2,797 and $1,908 per patient, respectively. CONCLUSIONS: The healthcare costs of AEs identified in the FAERS as having the strongest association with TKI treatment are substantial. Vascular stenosis-related AEs, including FAS and PAOD, have the highest cost burden.

Comparison of Healthcare Costs Among Commercially Insured Women in the United States Who Underwent Hysteroscopic Sterilization Versus Laparoscopic Bilateral Tubal Ligation Sterilization.

BACKGROUND: This study evaluated healthcare costs of index procedures and during a 6-month follow-up of women who had hysteroscopic sterilization (HS) versus laparoscopic bilateral tubal ligation (LBTL). MATERIALS AND METHODS: Women (18-49 years) with claims for HS and LBTL procedures were identified from the MarketScan commercial claims database (January 1, 2010, to December 31, 2012) and placed into separate cohorts. Demographics, characteristics, index procedure costs, and 6-month total healthcare costs and sterilization procedure-related costs were compared. Multivariable regression analyses were used to examine the impact of HS versus LBTL on costs. RESULTS: Among the study population, 12,031 had HS (mean age: 37.0 years) and 7286 had LBTL (mean age: 35.8 years). The majority (80.9%) who had HS underwent the procedure in a physician's office setting. Fewer women who had HS versus LBTL received the procedure in an inpatient setting (0.5% vs. 2.1%), an ambulatory surgical center setting (5.0% vs. 23.8%), or a hospital outpatient setting (13.4% vs. 71.9%). Mean total cost for the index sterilization procedure was lower for HS than for LBTL ($3964 vs. $5163, p < 0.0001). During the 6-month follow-up, total medical and prescription costs for all causes ($7093 vs. $7568, p < 0.0001) and sterilization procedure-related costs ($4971 vs. $5407, p < 0.0001) were lower for women who had HS versus LBTL. Multivariable regression results confirmed that costs were lower for women who had HS versus LBTL. CONCLUSIONS: Among commercially insured women in the United States, HS versus LBTL is associated with lower average costs for the index procedure and lower total healthcare and procedure-related costs during 6 months after the sterilization procedure.

Using Health Care Claims Data to Assess the Prevalence of Hodgkin Lymphoma and Relapsed or Refractory Hodgkin Lymphoma in the United States.

PURPOSE: Although most patients with Hodgkin lymphoma (HL) respond to primary therapy, some patients experience relapses or are refractory to treatment (RR-HL). The objectives of this study were to investigate the prevalence of HL and RR-HL in the United States by using a large health care claims database. METHODS: Patients with ≥1 diagnosis for HL between January 1, 2013, and September 30, 2014 (prevalence assessment period), in the MarketScan Commercial and Medicare databases were identified. RR-HL patients were identified as any HL patient with any record for either an autologous stem cell transplantation (ASCT) or brentuximab vedotin (BV) treatment between January 1, 2010, and September 30, 2014 (entire study period). Prevalence rates of HL and RR-HL were calculated as the number of patients with HL or RR-HL divided by the total number of persons with insurance enrollment during the prevalence assessment period (January 1, 2013-September 30, 2014) in the MarketScan databases. Age- and sex-specific prevalence rates for HL and RR-HL were estimated. The estimated prevalence rates based on the claims database analysis were applied to the US national population estimates from the US Census Bureau to project the national prevalence of HL and RR-HL in the United States. FINDINGS: Of persons with any insurance enrollment in the MarketScan databases during the prevalence assessment period (N = 58,968,235), 24,812 (0.04%) were identified as having HL (mean age, 48.6 years) between January 1, 2013, and September 30, 2014. Of this HL population, 712 (2.87%) were identified as RR-HL patients, with 432 (1.74%) having received ASCT, 199 (0.80%) having received BV, and 81 (0.33%) having received both ASCT and BV treatments during the study period. According to the national projection according to the US Census population estimate, the overall number of persons with HL in the United States was estimated at 149,615 (469.2 per 1 million) in 2014, with 2.72% (N = 4077; 12.8 per 1 million) having RR-HL. IMPLICATIONS: Among patients in the United States with HL, the proportion of RR-HL patients during the study period was estimated at <3% of the HL population.

Predictors of outcomes in patients with type 2 diabetes in the lixisenatide GetGoal clinical trials.

AIMS: To explore the treatment outcomes in adult patients with type 2 diabetes (T2D) enrolled in the GetGoal trials of lixisenatide (LIXI), and the predictive effects of baseline characteristics on outcomes. METHODS: This study was a pooled analysis of patient-level data from the LIXI GetGoal studies comparing LIXI and placebo. Patients were divided into baseline therapy groups: those receiving oral antidiabetes drugs (OADs) at baseline (n = 2760) or those receiving basal insulin at baseline (n = 1198). RESULTS: Compared with placebo, LIXI treatment led to significantly greater reductions in glycated haemoglobin (HbA1c), and greater achievement of the composite endpoint of HbA1c <7.0% (53 mmol/mol) with no symptomatic hypoglycaemia and no weight gain in either the OAD (34% vs 18%; P < .0001) or the basal insulin groups (19% vs 10%; P < .0001). Treatment with LIXI was associated with a greater percentage of patients experiencing a symptomatic hypoglycaemic event compared with placebo in both the OAD (5% vs 3%; P = .0098) and basal insulin groups (27% vs 17%; P < .0001). In assessing baseline factors that were predictors of treatment outcomes, only baseline HbA1c and LIXI treatment were strong predictors of outcomes in both the OAD and basal insulin groups. No other baseline characteristic had such a large or consistent clinically relevant predictive effect across treatment outcomes. CONCLUSIONS: The results from this study show that irrespective of baseline characteristics, LIXI treatment, as an add-on to OAD or basal insulin therapy, is effective in reducing HbA1c and achieving composite endpoints.

Efficacy of lixisenatide in patients with type 2 diabetes: A post hoc analysis of patients with diverse ß-cell function in the GetGoal-M and GetGoal-S trials.

AIMS: To evaluate the impact of ß-cell function on the efficacy of lixisenatide, a once-daily prandial glucagon-like peptide-1 receptor agonist, in patients with type 2 diabetes (T2D). MATERIALS AND METHODS: In this post hoc analysis, patients from the Phase 3 GetGoal-M and GetGoal-S clinical trials randomized to lixisenatide 20µg once daily were stratified into quartiles by baseline ß-cell function, as measured by the secretory units of islet in transplantation (SUIT) index. RESULTS: Patients (N=437) were distributed evenly among SUIT index quartiles 1 to 4 (lowest to highest ß-cell function). Clinical outcomes improved from baseline across all SUIT quartiles; mean changes at week 24 were: glycated hemoglobin (HbA1c; % [mmol/mol]), -0.99 (-10.8), -0.87 (-9.5), -0.86 (-9.4), -0.83 (-9.1); and postprandial plasma glucose (PPG; mmol/L), -7.9, -5.6, -5.5, -4.3 (overall effect P<0.0001). Furthermore, postprandial glucagon was reduced in all SUIT quartiles, while insulinogenic index improved only in patients with higher baseline SUIT (overall effect P=0.0286). No severe symptomatic hypoglycemic events were reported. CONCLUSIONS: Lixisenatide treatment resulted in reductions in HbA1c and PPG levels across all SUIT quartiles. This suggests that non-insulin-related actions of lixisenatide contribute to improved glycemic control in T2D.

Use of Real-World Claim Databases to Assess Prevalence of Comorbid Conditions Relevant to the Treatment of Chronic Myelogenous Leukemia Based on National Comprehensive Network Treatment Guidelines.

BACKGROUND: The National Comprehensive Cancer Network (NCCN) guidelines state that based on toxicity profiles, 1 second-generation tyrosine kinase inhibitor (TKI) indicated for first-line therapy (ie, dasatinib, nilotinib) may be preferred over the other for treatment of chronic myelogenous leukemia (CML) patients with certain comorbidities. This study assessed the prevalence of comorbid conditions relevant to TKI treatment choice among CML patients in the US real-world setting. PATIENTS AND METHODS: Patients who had CML and initiated TKI treatment were identified from the MarketScan Commercial and Medicare databases (January 1, 2006, to June 30, 2013). Demographics and prevalence of comorbid conditions relevant to TKI treatment choice per NCCN guidelines (heart disease, arrhythmia, diabetes, pancreatitis, pleural effusion, lung disease) were assessed among the overall study population and among subgroups. RESULTS: The median age of the CML study population newly initiated on TKI treatment (ie, imatinib, dasatinib, or nilotinib; n = 2296) was 56 years. Approximately 41% of the CML study population had at least 1 comorbid condition that may influence the choice of TKI treatment as recommended by NCCN guidelines. The most prevalent comorbid condition was heart disease (23%), followed by diabetes (18%) and lung disease (13%). The prevalence of comorbid conditions relevant to TKI treatment choice varied among patients of different age groups, gender, and US regions. CONCLUSION: The results of this analysis provide real-world evidence that the prevalence of relevant comorbid conditions is substantial among CML patients in the US managed care setting and therefore needs to be considered throughout various health care decision-making processes related to CML.
