Adjuvant and neoadjuvant treatment patterns among resectable pancreatic cancer patients in the USA.

Aim: Chemotherapy is standard before and/or after pancreatic cancer resection, yet benefits of pre-resection chemotherapy are unclear. Real-world pre- and post-resection treatment patterns were evaluated retrospectively. Methods: Neoadjuvant (3-months pre-surgery) and adjuvant (6-months post-surgery) treatment claims from 1 January 2016 to 31 December 2019 in US adults with resectable pancreatic cancer were analyzed. Results: Of the 737 patients, 29% received no chemotherapy in either setting; 22% received chemotherapy in both settings. In the neoadjuvant and adjuvant settings, 69 and 33% of patients, respectively, received no treatment at all. FOLFIRINOX and gemcitabine monotherapy were the most common chemotherapies in the neoadjuvant and adjuvant settings, respectively. Adjuvant FOLFIRINOX increased post-2018, whereas gemcitabine-based regimens decreased. Conclusion: Several chemotherapy regimens were used in both settings. Treatment patterns differed between the two settings.

Some patients diagnosed with pancreatic cancer can undergo surgery to remove the tumor. Standard of care is to treat the patient with chemotherapy after the surgery. Chemotherapy is sometimes given before the surgery, yet it is unknown if this pre-treatment is beneficial. This study used insurance claim data from patients with pancreatic cancer in USA to evaluate real-world pre- and post-surgery chemotherapy patterns. Of the 737 analyzed patients, almost a third did not receive chemotherapy at all whereas one-fifth received chemotherapy both pre- and post-surgery. More patients received chemotherapy post-surgery than pre-surgery. Several different chemotherapy regimens were used, but the most common regimens used recently were those that had evidence from clinical trials. Chemotherapy was given more often to patients less than 65 years old than those 65 years or older, indicating more aggressive treatment in younger patients. Overall, the study indicates that a variety of treatments are being used and treatment patterns differ pre- and post-surgery. However, our study also shows that treatment strategies continue to evolve as our understanding of treatment impact and outcomes improves.

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.

School absence and productivity outcomes associated with childhood asthma in the USA.

BACKGROUND: Previous studies have examined the association between childhood asthma and lost productivity; however, more data are needed to understand its impact. METHODS: This was a retrospective analysis of cross-sectional data in the nationally representative 2007-2013 Medical Expenditure Panel Survey (MEPS). School-aged children (SAC), children (age 6-11), and adolescents (age 12-17) with asthma were compared to those without asthma to examine annual missed school days. Adult parents/caregivers of SAC with asthma were compared to those of SAC without asthma to examine missed work days. The cost of premature asthma mortality for SAC was also estimated. Negative binomial regression was used for missed school days, and a two-part model structure was used for missed work days. All analyses controlled for sociodemographics and other covariates. RESULTS: There were 44,320 SAC of whom 5,890 had asthma. There were 43,496 employed adults with at least one child. SAC (6-17) with asthma missed 1.54 times the number of school days compared to SAC without asthma. Caregivers of SAC (6-17) with asthma missed 1.16 times the number of work days to care for others compared to caregivers of SAC without asthma. SAC in the USA missed an additional 7 million school days associated with asthma (3.7 million children and 3.3 million adolescent). There were 130 asthma deaths resulting in an annual cost of $211 million ($US 2015). CONCLUSIONS: Childhood asthma is associated with a significant school absence and productivity loss in the USA. Better treatment and asthma management programs are needed to alleviate this burden.

The national cost of asthma among school-aged children in the United States.

BACKGROUND: Recent research has quantified the national health care resource use (HCRU) and health care expenditure (HCE) burden associated with adult asthma; however, estimates specific to school-aged children are more than 2 decades old. OBJECTIVE: To estimate the national HCRU and HCEs attributable to asthma among school-aged children in the United States. METHODS: This was a cross-sectional retrospective analysis of school-aged children (aged 6-17 years) in the nationally representative 2007-2013 Medical Expenditure Panel Survey. All-cause HCRU and HCEs of school-aged children with asthma were compared with school-aged children without asthma, controlling for sociodemographics and comorbidities. HCRU encounters included emergency department (ED) and outpatient visits, hospitalizations, and prescriptions. Expenditures included total, medical, ED, inpatient, outpatient, and pharmacy. Negative binomial regression analyses were used for HCRU and Heckman selection with logarithmic transformation, and smearing retransformation was used for HCEs. RESULTS: There were 44,320 school-aged children of whom 5,890 had asthma. Children with asthma incurred a higher rate of all-cause annual ED visits (incidence rate ratio [IRR], 1.5; P < .001), hospitalizations (IRR, 1.4; P < .05), outpatient visits (IRR, 1.4; P < .001), and prescription drugs (IRR, 3.3; P < .001) compared with school-aged children without asthma. They incurred US$847 (2015 dollars) more annually in all-cause expenditures (P < .001). Private insurance and Medicaid paid the largest share of expenditures. Pharmacy and outpatient costs represented the largest proportion of total expenditures. On the basis of the nationally representative Medical Expenditure Panel Survey sample weights from 2013, the total annual HCEs attributable to asthma for school-aged children in the United States was US$5.92 billion (2015 dollars). CONCLUSION: Childhood asthma continues to represent a prevalent and significant clinical and economic burden in the United States. More aggressive treatment and asthma management programs are needed to address this national financial and resource burden.

Indicators of poorly controlled asthma and health-related quality of life among school-age children in the United States.

BACKGROUND: Poorly controlled asthma has far-reaching effects on school-age children and their parents, but little is known about the national impact on health-related quality of life (HRQoL). OBJECTIVE: To examine HRQoL associated with asthma and indicators of poorly controlled asthma in the United States. METHODS: This was a cross-sectional analysis of HRQoL among school-age children (age range, 6-17 years) with asthma in the nationally representative 2007-2013 Medical Expenditure Panel Survey (MEPS). Indicators of poor asthma control included the following: exacerbation in the previous 12 months, use of more than three canisters of short-acting beta agonist in 3 months, and annual asthma-specific emergency department or inpatient visits. Health status and HRQoL instruments included the following: the Columbia Impairment Scale (CIS), Child Health Questionnaire (CHQ), Children with Special Health Care Needs Screener (CSHCN), and self-perceived physical and mental health. Ordered logistic regression was used for ordered categorical variables, and logistic regression was used for binary variables. All regressions controlled for sociodemographics and other covariates. RESULTS: There were 44,320 school-age children in the MEPS, of whom 5890 had asthma. School-age children with indicators of poorly controlled asthma had higher odds of feeling unhappy and/or sad or nervous and/or afraid, and of having problems with sports and/or hobbies and schoolwork on the CIS. Results from the CHQ showed that parents of school-age children with asthma and indicators of poorly controlled asthma had higher odds of worrying about their child's health and future. Results from the CSHCN showed that school-age children with asthma and indicators of poorly controlled asthma were more likely to have special health care needs. School-age children with asthma and indicators of poorly controlled asthma had higher odds of having poor perceived physical health. CONCLUSION: This nationally representative study provided novel information on the burden of poorly controlled asthma on emotional problems, school-related and activity limitations, general health status, and worry among school-age children and their families as measured by validated instruments.

Persistency, medication prescribing patterns, and medical resource use associated with multiple sclerosis patients receiving oral disease-modifying therapies: a retrospective medical record review.

BACKGROUND: In the US, the approved multiple sclerosis (MS) oral disease-modifying therapies (ODMTs) are fingolimod (FTY), teriflunomide (TFN), and dimethyl fumarate (DMF). FTY and TFN are recommended with once-daily doses with no up-titration, whereas DMF treatment is recommended twice-daily (BID) and is initiated with a 7-day starter dose of 120 mg BID before up-titration to the maintenance dose of 240 mg BID. Limited information exists regarding real-world ODMT prescribing patterns to aid physician/patient decision-making. METHODS: Eligible patients for this retrospective medical record review were ≥18 years, had one visit related to ODMT initiation (index visit), and ≥1 visit within 12 months before and after the index visit. Primary objectives were to assess post-index ODMT persistency (i.e., discontinuation), prescribing patterns (medication switching, dose up-titrations, dose reduction, re-starts, and add-ons) and medical resource utilization (office-visits, MRI procedures, and mobility indicators) at distinct time windows of 3, 6, 9, and 12 months. Chi-square or Wilcoxon Rank Sum tests were used for 3-way ODMT group comparisons. RESULTS: Medical records of 293 MS-diagnosed patients using ODMTs were abstracted from 19 US-based neurology clinics between December 31, 2010 and June 30, 2014 (FTY: 101; DMF: 133; TFN: 59). Persistency rates among ODMT groups were similar. MS-related medication switching, dose reduction, re-starts, and add-ons were infrequently observed and were similar across ODMT groups. Of DMF patients with a confirmed starting dose of 120 mg BID with ≥12 months follow-up (n = 26), the percentage who were prescribed dose up-titrations to the recommended maintenance DMF dose was 23.1 % at 1-3 months, 26.9 % at 4-6 months, 42.3 % at 7-9 months, and 0 % at 10-12 months. There were no significant differences at any time window among the ODMT groups in the number of office visits or percent of patients receiving MRIs. Mobility indicator patterns (proportion of patients with abnormal gait, wheelchair use, etc.) were consistent over time. CONCLUSIONS: There was no difference in persistency, prescribing patterns (medication switching, dose reduction, re-starts, and add-ons) or medical resource utilization (office-visits, MRI procedures, and mobility indicators) among the ODMTs. However, in a small sub-group of patients, delays of up to 9 months in DMF dose-up titration to the recommended maintenance dose were observed.

Advancing Best Practices for Prescription Drug Labeling.

OBJECTIVE: Problematic prescription drug labeling has been cited as a root cause of patient misunderstanding, medication errors, and nonadherence. Although numerous studies have recently been conducted to identify and test labeling best practices, the last systematic review on this topic was conducted a decade ago. The objective of this review was, therefore, to examine, summarize, and update best practices for conveying written prescription medication information and instructions to patients. DATA SOURCES: English-language articles published from June 2005 to June 2015 were identified in MEDLINE and CINAHL by searching the following text words: 'medication OR prescription OR drug' AND 'label OR leaflet OR brochure OR pamphlet OR medication guide OR medication insert OR drug insert OR medication information OR drug information OR instructions' AND 'patient OR consumer.' Reference mining and secondary searches were also performed. STUDY SELECTION AND DATA EXTRACTION: A total of 31 articles providing evidence on how to improve written, prescription drug labeling for patient use were selected. Two reviewers independently screened articles, rated their quality, and abstracted data. DATA SYNTHESIS: Identified best practices included the use of plain language, improved formatting and organization, and more explicit instructions to improve patient comprehension. The use of icons had conflicting findings, and few studies tested whether practices improved knowledge or behaviors with patients' actual prescribed regimens. CONCLUSIONS: Future studies are needed to determine how specific modifications and improvements in drug labeling can enhance patient knowledge and behavior in actual use. Synthesizing best practices across all patient materials will create a more useful, coordinated system of prescription information.

Moderate symptom-based exacerbations as predictors of severe claims-based exacerbations in asthma.

OBJECTIVES: Asthma exacerbations have well-established clinical and economic impact, yet lack consensus on characterization of an episode's severity. Asthma treatment guidelines outline the concept of a moderate asthma exacerbation; however, a clear definition that can be operationalized has not been proposed, METHODS: Adult asthma (ICD-9: 493.XX) patients, with at least 9 months of continuous enrolment in the Fallon Community Health Plan were included in the retrospective cohort study. Patients diagnosed with Chronic Obstructive Pulmonary Disease (COPD) or other lower respiratory tract conditions were excluded. The first reported asthma-related event following a 2-week symptom-free period was designated as the index event. Asthma-related events were categorized as (1) moderate exacerbations (symptom-based) or (2) severe exacerbations (claims-based). Timing between and temporal sequence of asthma-related events along with average costs were calculated, RESULTS: Of 3126 eligible patients, 55% reported an asthma-related event followed by a recurrent event(s). Moderate exacerbations followed by recurrent moderate exacerbations were most frequent (20%) with the shortest interval between exacerbations (mean: 83 days [SD 87]). Moderate exacerbations followed by severe exacerbations occurred in 16% of patients with an average of 176.74 (SD 176.94) days between events, CONCLUSIONS: Patient report of asthma bothersome enough to initiate contact with a clinician, but not requiring oral corticosteroid (OCS), is a definition for a moderate exacerbation that can be operationalized for research purposes. Further work is needed to demonstrate whether identification of moderate exacerbations will allow interventions that impact the frequency and timing of future exacerbations.

Levodopa treatment patterns in Parkinson's disease: A retrospective chart review.

BACKGROUND: Medication regimens for Parkinson's disease (PD) may change as the disease progresses, symptoms fluctuate, or medication-related adverse events occur. This study evaluated treatment trends by observation year for patients initially receiving monotherapy with levodopa and a peripheral dopa decarboxylase inhibitor (PDDI). METHODS: In this retrospective chart review, therapy changes were evaluated for patients across the US diagnosed with PD on or before 6/30/2014 who initially received levodopa-PDDI monotherapy. Index date was the first clinic visit. Post-index was any time between the first 31 days after index and study end (6/30/2019). Index Hoehn-Yahr (H-Y) score and medication changes were also analyzed by index low (<400 mg/day) or high (≥400 mg/day) levodopa doses in the levodopa-PDDI combinations. RESULTS: In the levodopa-PDDI cohort (n = 95), there were 0.39 dose escalations, 0.16 dose reductions, 0.12 discontinuations, 0.19 therapy switches, and 0.24 add-ons per patient per year during the study. Most dose escalations or add-ons occurred within the first 6 months post-index. Of those who ever stopped levodopa-PDDI (n = 34), 31 (91%) restarted within the study period. Most (83%) patients who restarted levodopa-PDDI did so in the same year as stopping treatment. Index low dose users were associated with lower H-Y scores, were more inclined to escalate their dose, and were less inclined to reduce their dose in the first 2 years of treatment than index high dose users. CONCLUSIONS: Prescribers and patients tend to experiment with levodopa-PDDI treatment. Although many patients appeared to stop levodopa-PDDI after an initial course of treatment, most subsequently restarted treatment.

Natural history and patterns of treatment change in Parkinson's disease: A retrospective chart review.

BACKGROUND: Parkinson's disease (PD) management seeks to balance the benefits and harms of current medications and evolves as the disease progresses. The natural history of PD and associated patterns of treatment change were analyzed to identify unmet needs in treatment of PD symptoms. METHODS: Medical charts of patients from clinics across the US diagnosed on or before June 30th, 2014 were retrospectively reviewed. Index date was the first clinic visit, and the post-index period was through study end (June 30th, 2019). Outcomes included the frequency of therapy changes in the post-index period, reasons for therapy change, and adverse events (AE). RESULTS: Patients (n = 203) at index were receiving levodopa-peripheral dopa decarboxylase inhibitor (PDDI) monotherapy (47%), dopaminergic agonist (DA) monotherapy (15%), monoamine oxidase B inhibitor (MAOBI) monotherapy (14%), or combination therapies. The percentage of patients in Hoehn-Yahr disease Stage 1-2 was 52% at index and 20% by the end of the study. Frequencies of motor, non-motor, and neuropsychiatric symptoms increased during the enrollment. Levodopa-PDDI monotherapy and levodopa-PDDI + MAOBI had the lowest rates of therapy changes. Symptom relapse was the most common reason for dose escalation, add-on, and dose reduction, whereas AEs were the most common reason for discontinuation and switching. Dose escalation, add-on, and forward switch were most likely to occur in the first 6 months of treatment. CONCLUSIONS: Therapy changes during the study period reflected the challenging and evolving management of PD as the disease progresses. New or add-on symptomatic treatments are needed that are well-tolerated and able to control PD symptoms.

Treatment with inhaled mometasone furoate reduces short-acting ß(2) agonist claims and increases adherence compared to fluticasone propionate in asthma patients.

OBJECTIVES: Differences between mometasone furoate (MF), administered once daily, and fluticasone propionate (FP), administered twice daily, dosing regimens may affect adherence and short-acting ß(2) agonist (SABA) use. The objective of this analysis was to compare asthma control outcomes in matched cohorts of MF- and FP-treated asthma patients stratified by SABA claims. METHODS: A retrospective pharmacy claims database analysis identified matched cohorts of asthma patients (aged 12-65 years) who initiated treatment with MF or FP. Patients with none, one to four, five to eight, or more than eight SABA preindex claims were stratified to categories A, B, C, and D, respectively. Bivariate analyses compared postindex SABA canister claims, adherence, and exacerbations; multivariate analyses compared postindex SABA canister claims. RESULTS: Matched patients in categories A (n = 2517 per cohort) and B (n = 2329 per cohort) were analyzed; insufficient sample sizes were identified for categories C and D. Postindex bivariate analyses indicated that MF cohorts had fewer SABA claims compared to FP cohorts (category A, 0.80 vs. 1.17 [P < 0.0001]; category B, 1.39 vs. 1.58 [P < 0.0001]), better adherence to the index drug (category A, 24% vs. 15% [P < 0.0001]; category B, 27% vs. 15% [P < 0.0001]), and fewer exacerbations (category A, 0.17 vs. 0.19 [P = 0.011]; category B, 0.17 vs. 0.21 [P = 0.008]). Multivariate analyses indicated that MF cohorts had fewer postindex SABA claims compared to FP cohorts in categories A and B (P < 0.0001). CONCLUSIONS: Data for SABA claims, treatment adherence, and exacerbations suggest that, compared to twice-daily FP, once-daily MF may provide better asthma control.

An assessment of change in asthma control among adolescents and adults with persistent asthma in mometasone furoate/formoterol fumarate clinical trials.

OBJECTIVE: This article provides evidence on the psychometric properties of the Asthma Control Questionnaire (ACQ) in adolescent and adult patients with persistent asthma treated with a combination of inhaled glucocorticoid and long-acting beta2-agonist (LABAs), and explores the factors associated with important improvements in asthma control. METHODS: Data from patients in two large (n = 737 and 772) Phase III, randomized, double-blind, parallel-group, multi-center, placebo-controlled studies of mometasone furoate/formoterol fumarate (MF/F) combination formulation compared with monotherapies in subjects with persistent asthma previously treated with either low- or medium-dose inhaled glucocorticoids were used to evaluate the ACQ psychometric properties and predictors of important ACQ improvement, defined as an ACQ score decline from baseline of 0.5 or more at the end of treatment. RESULTS: With 15% and 8% participation from adolescents in the low- and medium-dose studies, the ACQ yielded acceptable reliability (intraclass correlation coefficient ≥ 0.75), and baseline and change scores demonstrated moderate to strong correlations with other baseline measures and change scores in other measures of asthma-related health, including the Asthma Quality of Life Questionnaire (AQLQ12+) domains and total scores. More MF/F treatment group patients (48%) achieved an important ACQ change at 26 weeks compared with MF (32%), F (26%), and placebo (18%) treatment groups (p < .001). Use of rescue medications before randomization was a significant predictor of important ACQ improvement in both studies. CONCLUSIONS: These findings support the psychometric properties of the ACQ to measure asthma control among persistent asthma patients and provide confidence in the significant improvements in asthma control demonstrated by the MF/F treatment group.

Validation of the AQLQ12+ among adolescents and adults with persistent asthma.

BACKGROUND: To date, there is limited psychometric evidence on the Asthma Quality of Life Questionnaire (AQLQ12 +) among populations that include adolescents and adults. OBJECTIVE: To provide evidence of the psychometric properties of the AQLQ12+ as a measure of asthma-specific quality of life (QOL) in patients with persistent asthma treated with a combination of inhaled glucocorticoid and long-acting beta2-agonist, as well as explore the predictors of at least a minimally important AQLQ12+ improvement. METHODS: The psychometric properties of the AQLQ12+ were assessed through post hoc analysis of two large (n = 740 and 778) Phase III, randomized, double-blinded, placebo-controlled efficacy studies of mometasone furoate/formoterol fumarate (MF/F) combination compared with monotherapy in subjects with persistent asthma previously treated with either low-dose or medium-dose inhaled glucocorticoids. RESULTS: With 15% and 8% participation from 12- to 17-year olds, blinded trial data demonstrated excellent reproducibility (ICC range: 0.76-0.85) and moderate-to-strong construct validity with other measures of asthma health at baseline and over time for the AQLQ12 +. A greater percentage of the MF/F treatment group (44%) achieved an important change at 26 weeks on the AQLQ12+ compared with formoterol fumarate (F, 23%) and placebo (18%) treatment groups in the low-dose study (P < 0.001) and the medium-dose study (50% (MF/F) versus 34% (F) and 23% (placebo); P < 0.001). Pre-randomization nighttime awakenings and rescue medications use were significant predictors of AQLQ12+ improvement. CONCLUSIONS: These findings provide strong support for the measurement properties of the AQLQ12+ among patients with persistent asthma and confidence in the AQLQ12+ improvements demonstrated by the MF/F treatment group.

Adherence and asthma control with mometasone furoate versus fluticasone propionate in adolescents and young adults with mild asthma.

INTRODUCTION: Because adherence to asthma controller medication among adolescents and young adults is poor but critical for asthma control, strategies are needed to improve adherence. One strategy is to reduce the number of daily doses necessary to maintain adequate control. Mometasone furoate delivered through a dry powder inhaler (MF-DPI) is an inhaled corticosteroid (ICS) approved for once-daily dosing in most patients. Fluticasone propionate (FP) is an ICS approved for twice-daily dosing. A retrospective claims analysis was performed to assess treatment adherence and markers of asthma control in adolescent and young adult patients with mild asthma who began treatment with MF-DPI or FP. METHODS: Data from approximately 37 million patients in an administrative insurance claims database in the United States were analyzed. Patients, 12-25 years, with mild asthma and previous asthma medication use were assigned an index date based on their first prescription fill of MF-DPI or FP between 1 January 2005 and 10 October 2008. Demographics, prescription claims, and health care utilization data were captured in the 365-day period before (preindex) and after (postindex) the index date. Patients from each cohort were propensity score-matched 1:1 based on preindex data. Adherence was measured by prescription fills and percentage of days covered (PDC); asthma control was measured by exacerbations and short-acting ß2-agonist (SABA) canister claims. Bivariate and multivariate generalized linear model (GLM) analyses were conducted to determine differences in outcomes between the cohorts. RESULTS: After matching, 692 patients per group (average age - 16 years) were analyzed. Adherence in the postindex period was significantly higher in the MF-DPI cohort compared with the FP cohort as measured by PDC (23.5% vs. 14.5%; p< .0001) and prescription fills (2.70 vs. 1.91; p< .0001). The mean number of postindex SABA canister claims was significantly lower in the MF-DPI cohort compared with the FP cohort (1.04 vs. 1.40; p< .0001). There was no significant difference in the mean number of postindex exacerbations between the cohorts. CONCLUSION: Adolescent/young adult patients with mild asthma who received MF-DPI had better postindex adherence and fewer SABA canister claims than patients receiving FP.

Observational study comparing intranasal mometasone furoate with oral antihistamines for rhinitis and asthma.

AIMS: Retrospective database study comparing upper and lower airway-related outcomes for patients with rhinitis and co-morbid asthma receiving mometasone furoate--an intranasal corticosteroid with low systemic bioavailability--or an oral antihistamine. METHODS: 395 patients prescribed intranasal mometasone were matched on 10 demographic and respiratory-related criteria in a 1:2 ratio to 790 patients prescribed oral antihistamine. Asthma and rhinitis control were assessed over one year using predefined composite proxy measures. RESULTS: Asthma control was achieved by 309/395 (78.2%) versus 580/790 (73.4%; p=0.071) patients in the mometasone and antihistamine cohorts, respectively. Rhinitis control was achieved by 293 (74.2%) versus 539 (68.2%; p=0.035), respectively. The adjusted odds ratios for antihistamines, relative to mometasone, were 0.71 (95% CI, 0.52-0.98) for achieving asthma control and 0.74 (95% CI, 0.56-0.97) for achieving rhinitis control. CONCLUSIONS: Patients with rhinitis and co-morbid asthma initiating rhinitis therapy achieved significantly better upper as well as lower airway outcomes with intranasal mometasone than with oral antihistamine.

Risk assessment of post-discharge mortality among recently hospitalized Medicare heart failure patients with reduced or preserved ejection fraction.

Objective: Targeted care management for hospitalized patients with acute decompensated heart failure (ADHF) with reduced or preserved ejection fraction (HFrEF/HFpEF) who are at higher risk for post-discharge mortality may mitigate this outcome. However, identification of the most appropriate population for intervention has been challenging. This study developed predictive models to assess risk of 30 day and 1 year post-discharge all-cause mortality among Medicare patients with HFrEF or HFpEF recently hospitalized with ADHF.Methods: A retrospective study was conducted using the 100% Centers for Medicare Services fee-for-service sample with complementary Part D files. Eligible patients had an ADHF-related hospitalization and ICD-9-CM diagnosis code for systolic or diastolic heart failure between 1 January 2010 and 31 December 2014. Data partitioned into training (60%), validation (20%) and test sets (20%) were used to evaluate the three model approaches: classification and regression tree, full logistic regression, and stepwise logistic regression. Performance across models was assessed by comparing the receiver operating characteristic (ROC), cumulative lift, misclassification rate, the number of input variables and the order of selection/variable importance.Results: In the HFrEF (N = 83,000) and HFpEF (N = 123,644) cohorts, 30 day all-cause mortality rates were 6.6% and 5.5%, respectively, and 1 year all-cause mortality rates were 33.6% and 29.5%. The stepwise logistic regression models performed best across both cohorts, having good discrimination (test set ROC of 0.75 for both 30 day mortality models and 0.74 for both 1 year mortality models) and the lowest number of input variables (18-34 variables).Conclusions: Post-discharge mortality risk models for recently hospitalized Medicare patients with HFrEF or HFpEF were developed and found to have good predictive ability with ROCs of greater than or equal to 0.74 and a reasonable number of input variables. Applying this risk model may help providers and health systems identify hospitalized Medicare patients with HFrEF or HFpEF who may benefit from more targeted care management.

Comparative analysis of length of stay, total costs, and treatment success between intravenous moxifloxacin 400 mg and levofloxacin 750 mg among hospitalized patients with community-acquired pneumonia.

OBJECTIVE: This study aimed to evaluate the length of stay (LOS), costs, and treatment consistency among patients hospitalized with community-acquired pneumonia (CAP) initially treated with intravenous (IV) moxifloxacin 400 mg or IV levofloxacin 750 mg. METHODS: Adults with CAP receiving IV moxifloxacin or IV levofloxacin for > or =3 days were identified in the Premier Perspective comparative database. Primary outcomes were LOS and costs. Secondary outcomes included treatment consistency, which was defined as 1) no additional IV moxifloxacin or levofloxacin after > or =1 day off study drug; 2) no switch to another IV antibiotic; and 3) no addition of another IV antibiotic. RESULTS: A total of 7720 patients met inclusion criteria (6040 receiving moxifloxacin; 1680 receiving levofloxacin). Propensity matching created two cohorts (1300 patients each) well matched for demographic, clinical, hospital, and payor characteristics. Before the patients were matched, mean LOS (5.87 vs. 5.46 days; P = 0.0004) and total costs per patient ($7302 vs. $6362; P < 0.0001) were significantly greater with moxifloxacin. After the patients were matched, mean LOS (5.63 vs. 5.51 days; P = 0.462) and total costs ($6624 vs. $6473; P = 0.476) were comparable in both cohorts. Treatment consistency was higher for moxifloxacin before (81.0% vs. 78.9%; P = 0.048) and after matching (82.8% vs. 78.0%; P = 0.002). CONCLUSIONS: In-hospital treatment of CAP with IV moxifloxacin 400 mg or IV levofloxacin 750 mg was associated with similar hospital LOS and costs in propensity-matched cohorts.

Health Disparities Among Children with Asthma in the United States by Place of Residence.

BACKGROUND: Children residing in poor-urban areas may have greater asthma morbidity. It is unclear whether this is due to individual characteristics such as race and ethnicity or place of residence. OBJECTIVE: Assess indicators of control and treatment by residence. METHODS: This was a cross-sectional analysis of children (aged 1-17 years) in the 2000-2014 Medical Expenditure Panel Survey (MEPS). Indicators of poor control included use of more than 3 canisters of short-acting beta agonist (SABA) in 3 months, asthma attack, and emergency department (ED) or inpatient (IP) visit during the year. Treatment measures included use of controller medications and a ratio of controller-to-total prescriptions of 0.7 or more. RESULTS: There were 15,052 children with asthma in the MEPS 2000-2014 data, reflecting 8.4 million children in 2014. After controlling for covariates, children with asthma residing in poor-urban areas had lower odds of using controller medications (odds ratio [OR] = 0.77), having a controller-to-total ratio of 0.7 or more (OR = 0.75), and reporting an asthma attack (OR = 0.75) and higher odds of having an ED/IP visit (OR = 1.3) compared with those living elsewhere. Black race and Hispanic ethnicity were associated with greater odds of excessive SABA use (OR = 2.11) and ED/IP visits (OR = 2.03) and lower odds of controller-to-total ratio of 0.07 or more (OR = 0.50). CONCLUSIONS: Poor-urban residence may be independently associated with asthma control and treatment even after controlling for individual characteristics such as race and ethnicity. Future research is needed to understand the sources of these geographic health disparities to more successfully target public health interventions.

Trends in Asthma Control, Treatment, Health Care Utilization, and Expenditures Among Children in the United States by Place of Residence: 2003-2014.

BACKGROUND: Examining national trends in asthma treatment and control is essential to inform treatment and public health initiatives. OBJECTIVE: Explore national trends in asthma control and treatment over time among children and those residing in poor-urban areas. METHODS: This was an analysis of trends from 2003 to 2014 among children (aged 1-17 years) in the Medical Expenditure Panel Survey. Indicators of poor control included use of more than 3 canisters of short-acting ß-agonists (SABAs) in 3 months, asthma attack, emergency department/inpatient hospitalization, and systemic corticosteroids. Treatment included inhaled corticosteroids, controller medications, SABAs, and greater than or equal to 0.7 ratio of controller-to-total prescriptions. Other measures included the number of asthma medications, outpatient visits, asthma-specific drug, and total expenditures per-patient-per-year. RESULTS: There were 8.4 million children with asthma in the United States in 2014; 11.1% lived in poor-urban areas. There was a statistically significant decrease in the percentage of children using inhaled corticosteroids, controller medications, daily preventive medications, systemic corticosteroids, SABAs, more than 3 canisters of SABAs (in 3 months), overall asthma prescriptions, and outpatient visits. There was a significant increase in the percentage of children reporting having an asthma attack. Trends for children residing in poor-urban areas were compared with all others; however, limited data and variability in annual estimates prevent clear conclusions. CONCLUSIONS: Results suggest lack of improvement in treatment and control since 2003 among children with asthma in the United States. There is significant room for improvement in asthma control and disease management among children.

National Prevalence of Poor Asthma Control and Associated Outcomes Among School-Aged Children in the United States.

BACKGROUND: The degree of asthma control among school-aged children (SAC) nationally is not well understood. OBJECTIVE: The objective of this study was to characterize poor control among SAC (aged 6-17 years) in the United States. METHODS: This was a retrospective analysis of the 2007-2013 Medical Expenditure Panel Survey. Indicators of poor control included exacerbation in previous year; use of >3 canisters of short-acting ß-agonist (SABA) in 3 months; and asthma-specific (AS) emergency department (ED) or inpatient (IP) visits. Treatment indicators included daily controller medication and peak flow meter use. Negative binomial regression was used for health resource utilization (HRU); generalized linear models with log-link were used for health care expenditures. RESULTS: There were 44,320 SAC, of whom 5,890 had asthma. The prevalence of poor control and treatment among SAC with asthma were as follows: exacerbation (59%), >3 canisters of SABA (4%), ED/IP visit (3%), daily controller (19%), peak flow (12%). In 2013, 3.4 million SAC had an asthma exacerbation and 200,000 had an AS ED/IP visit. SAC with asthma and an exacerbation had 18.9 times more annual AS ED visits (and 43.3 times more AS hospitalizations) than SAC with asthma but no exacerbation. SAC with asthma and an indicator of poor control incurred greater annual all-cause expenditures than SAC without asthma ($US 2015): $1,144 (exacerbation), $1,859 (≥3 canisters of SABA), and $3,063 (ED/IP visit). Use of daily controller medication was low even among SAC with poor control (27% to 61%). CONCLUSION: Renewed and vigilant asthma management and treatment is necessary to mitigate the current and long-term public health effects and expenditures associated with poor asthma control.
