Aims: The objective of this study was to evaluate diabetes-related healthcare resource use and associated costs in patients with type 2 diabetes (T2DM) treated with a sulfonylurea (SU), with and without hypoglycemia.Methods: In this retrospective cohort study, patients 18years or older receiving SU monotherapy or as add-on to metformin were identified from a US healthcare claims database (MarketScan®). Of 113,743 patients (56.8% male, average age 62.6years), 61.6% were on SU/metformin dual therapy and 38.4% were on SU monotherapy, and 5% had one or more episodes of hypoglycemia during the 12-month follow-up period.Results: Adjusted for baseline characteristics, patients with hypoglycemia were three times more likely than those without to use emergency room services (OR 3.04, 95% CI: 2.82, 3.25), almost four times more likely to have inpatient admissions (OR 3.84, 95% CI: 3.58, 4.12), and had more frequent physician office visits (4.3 vs 3.0 visits, p<0.01) in the 12-month follow-up period. The adjusted annual diabetes-related medical expenditure was three times higher in patients with hypoglycemia compared with those without ($6884 vs $2392, p<0.001).Conclusions: This study demonstrated the higher healthcare utilization and costs associated with hypoglycemia in patients with T2DM treated with an SU.

Background: Asthma exacerbations are frequent in patients with severe disease. This report describes results from two retrospective cohort studies describing exacerbation frequency and risk, emergency department (ED)/hospital re-admissions, and asthma-related costs by asthma severity in the US and UK.Methods: Patients with asthma in the US-based Clinformatics™ DataMart Multiplan IMPACT (2010-2011; WEUSKOP7048) and the UK-based Clinical Practice Research Datalink (2009-2011; WEUSKOP7092) databases were categorized by disease severity (Global Initiative for Asthma [GINA]; Step and exacerbation history) during the 12 months pre-asthma medical code (index date). Outcomes included: frequency of exacerbations (asthma-related ED visit, hospitalization, or oral corticosteroid use with an asthma medical code recorded within ±2 weeks) 12 months post-index, asthma-related ED visits/hospitalization, and asthma-related costs 30 days post-index. Risk of a subsequent exacerbation was determined by proportional hazard model.Results: Of the 222,817 and 211,807 patients with asthma included from the US and UK databases, respectively, 12.5 and 8.4% experienced ≥1 exacerbation during the follow-up period. Exacerbation frequency increased with disease severity. Among the 5,167 and 2,904 patients with an asthma-related ED visit/hospitalization in the US and UK databases, respectively, 9.2 and 4.7% had asthma-related re-admissions within 30 days. Asthma-related re-admission rates and costs increased with disease severity, approximately doubling between GINA Step 1 and 5 and in patients with ≥2 versus <2 exacerbations in the previous year. Risk of a subsequent exacerbation increased 32-35% for an exacerbation requiring ED visit/hospitalization versus oral corticosteroids.Conclusion: Increased disease severity was associated with higher exacerbation frequency, ED/hospitalization re-admission, costs and risk of subsequent exacerbation, indicating that these patients require high-intensity post-exacerbation management.

BACKGROUND AND OBJECTIVES: Croup is a clinical diagnosis, and the available evidence suggests abstract that, except in rare cases, ancillary testing, such as radiologic imaging, is not helpful. Given the paucity of inpatient-specific evidence for croup care, we hypothesized that there would be marked variability in the use of not routinely indicated resources (NRIRs). Our primary study objective was to describe the variation and predictors of variation in the use of NRIRs. METHODS: This was a retrospective cohort study that used the Pediatric Health Information System database of generally healthy inpatients with croup aged 6 months to 15 years who were admitted between January 1, 2012 and September 30, 2014. We measured variability in the use of NRIRs: chest and lateral neck radiographs, viral testing, parenteral steroids, and antibiotics. Risk-adjusted analysis was used to compare resource utilization adjusted for hospital-specific effects and average case mix. RESULTS: The cohort included 26 hospitals and 6236 patients with a median age of 18 months. Nine percent of patients required intensive care services, and 3% had a 30-day readmission for croup. We found marked variability in adjusted and unadjusted utilization across hospitals for all resources. In the risk-adjusted analysis, hospital-specific effects rather than patient characteristics were the main predictor of variability in the use of NRIRs. CONCLUSIONS: We observed an up to fivefold difference in NRIR utilization attributable to hospital-level practice variability in inpatient croup care. This study highlights a need for inpatient-specific evidence and quality-improvement interventions to reduce unnecessary utilization and to improve patient outcomes. [ABSTRACT FROM AUTHOR]

Introduction: The objective of this study was to analyze medical costs and healthcare resource utilization (HRU) associated with everolimus-based therapy or chemotherapy among elderly women with hormone-receptor-positive, human-epidermal-growth-factor-receptor-2-negative (HR+/HER2-) metastatic breast cancer (mBC).Methods: Elderly women (≥65 years) with HR+/HER2- mBC who failed a non-steroidal-aromatase-inhibitor and subsequently began a new line of treatment with everolimus-based therapy or chemotherapy for mBC (index therapy) during July 20, 2012 to March 31, 2014 were identified from two large commercial claims databases. All-cause, BC-, and adverse event (AE)-related medical costs (2014 USD), and all-cause and AE-related HRU per patient per month (PPPM) were compared between patients treated with everolimus-based therapy and chemotherapy across their first four lines of therapy for mBC. Adjusted costs and HRU differences were estimated by pooling all lines and using multivariable models adjusted for differences in patient characteristics.Results: In total, 925 elderly patients (mean age approximately 73 years) with HR+/HER2- mBC met the inclusion criteria; 230 received everolimus-based therapy (240 lines) and 737 received chemotherapy (939 lines). Compared with chemotherapy, everolimus-based therapy was associated with significantly lower total all-cause PPPM medical services costs (adjusted mean difference: $4007), driven by lower inpatient ($1994) and outpatient ($1402) costs; lower BC-related medical services costs ($3129), driven by both BC-related inpatient ($1883) and outpatient costs ($913); and lower AE-related medical services costs ($1873; all P < 0.01). Additionally, compared to patients treated with chemotherapy, patients treated with everolimus-based therapy had fewer all-cause outpatient visits (adjusted incidence rate ratio = 0.69), BC-related outpatient visits (0.66), other-medical-service visits (0.65), and AE-related HRU (0.59), which was driven by significantly fewer AE-related outpatient visits (0.56; all P < 0.01). Subgroup analyses comparing medical costs of everolimus-based therapy with capecitabine monotherapy showed consistent results overall.Conclusion: This retrospective claims database analysis of elderly women with HR+/HER2- mBC in the United States showed that everolimus-based therapy was associated with significantly lower all-cause, BC-related, and AE-related medical services costs and less use of healthcare resources compared with chemotherapy.Funding: Novartis.

Objectives: As the prevalence of peripheral artery disease (PAD) increases there is growing concern about the associated healthcare burden. This burden has not been well-characterized in high-risk patients with concurrent diabetes and/or acute coronary syndrome (ACS). The objective of this analysis was to assess comorbidities, medication use, outcomes, services and costs for 3 high-risk symptomatic PAD groups.Methods: This retrospective longitudinal analysis used the MarketScan Commercial Claims and Encounters Database (2005-2013). The 3 high-risk symptomatic PAD groups were (1) symptomatic PAD with/without diabetes, (2) symptomatic PAD with/without prior ACS, and (3) symptomatic PAD with/without diabetes and prior ACS. The study time frame was a period of 1-year before the earliest date of a symptomatic PAD record and 3 years post.Results: In all, 16,663 symptomatic PAD patients were identified across the three risk groups. Mean age ranged from 66.4-67.4 years; the majority (55.0%-63.3%) were men. At 3 years post index, patients with symptomatic PAD and a risk factor had significantly higher use of beta-blockers, ACE inhibitors and statins (P<0.0007), and higher rates of all-cause and symptomatic PAD-related medical services, diagnoses and procedures (P<0.05). Clopidogrel and statins were used by ≤ 41.2% and ≤ 66.7% of symptomatic PAD patients without risk, respectively, and ≤ 68.9% and ≤ 80.2% of patients with risks. All cause and symptomatic PAD-related treatment costs (P<0.0001) were higher for symptomatic PAD patients with risks versus patients without risks where annualized all-cause cost differences ranged from $7,482 to $13,504 and annualized PAD-related cost differences ranged from $605 to $1,997.Conclusions: Symptomatic PAD patients with diabetes and/or prior ACS have significantly higher medical resource use and costs compared to symptomatic PAD patients without these risk factors. The utilization rate of secondary prevention therapies is suboptimal; therefore, greater effort must be made to increase utilization and optimize treatment to minimize the impact of symptomatic PAD.

Background: Patients with asthma and chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) have more rapid disease progression and more exacerbations than do those with either condition alone. Little research has been performed, however, in these patients.Objective: The objective was to summarize the health care utilization, costs, and comorbidities of patients with uncontrolled asthma and patients with ACOS.Methods: This retrospective analysis used medical and pharmacy claims from large commercial health plans. The study included patients 6 years or older with a diagnosis of asthma and one or more asthma exacerbation (index event). Patients were classified as having asthma alone or ACOS, and the two groups were matched for age, sex, region, index year, index month, and health plan type. Outcomes included rates of comorbid disease, health care utilization, and costs during the 12 months before and after the index exacerbation.Results: Among the matched patients with asthma (6,505 ACOS; 26,060 without COPD), mean annual all-cause health care costs were twice as high as for patients with ACOS ($22,393 vs. $11,716; P < 0.0001). Asthma-related costs, representing 29% of total costs, were nearly twice as high among patients with ACOS ($6,319 vs. 3,356; P < 0.0001). Cost differences were driven by large differences in the proportions of patients with an inpatient hospitalization (34.0% vs. 14.6%; P < 0.0001) or emergency department visit (29.6% vs. 19.9%; P < 0.0001). Nearly all prespecified comorbid conditions were more prevalent in the ACOS group.Conclusions: Patients with asthma and COPD had nearly double the health care costs as did patients with asthma without COPD. The overall disease profile of patients with asthma should be considered when managing patients, rather than treating asthma as a solitary condition. [ABSTRACT FROM AUTHOR]

Background: Emergency treatment of bleeding esophageal varices (BEV) in cirrhotic patients is of prime importance because of the high mortality rate surrounding the episode of acute bleeding. Nevertheless, there is a paucity of randomized controlled trials of emergency surgical therapy and no reports of the costs of any of the widely used forms of emergency treatment. The important issue of direct costs of care was examined in a randomized controlled trial that compared endoscopic sclerotherapy (EST) to emergency portacaval shunt (EPCS).Methods: Two hundred eleven unselected consecutive patients with ultimately biopsy-proven cirrhosis and endoscopically proven acute BEV were randomized to EST (n = 106) or EPCS (n = 105). Diagnostic workup was completed, and EST or EPCS was initiated within 8 h. Criteria for failure of EST or EPCS were clearly defined, and crossover rescue treatment was applied, when primary therapy failed. Ninety-six percent of patients underwent more than 10 years follow-up, or until death. Complete charges for all aspects of care were obtained continuously for more than 10 years.Results: Direct charges for all aspects of care were significantly lower in patients treated by EPCS than in patients treated by emergency EST followed by long-term repetitive sclerotherapy. Charges per patient, per year of treatment, and per year in each child's risk class were significantly lower in patients randomized to EPCS. Charges in patients who failed endoscopic sclerotherapy and underwent a rescue portacaval shunt were significantly higher than the charges in both the unshunted sclerotherapy patients and the patients randomized to EPCS. This result was particularly noteworthy given the widespread practice of using surgical portacaval shunt as rescue treatment only when all other forms of therapy have failed.Conclusions: In this randomized controlled trial of emergency treatment of acute BEV, EPCS was significantly superior to EST with regard to direct costs of care as reflected in charges for care as well as in survival rate, control of bleeding, and incidence of portal-systemic encephalopathy. These results provide support for the use of EPCS as a first line of emergency treatment of BEV in cirrhosis. [ABSTRACT FROM AUTHOR]
