Objective To assess the impact of osteoporosis on health care costs for patients with chronic disease (CD): cardiovascular disease (CVD), chronic obstructive pulmonary disease (COPD), depression, diabetes mellitus (DM), or two or more of these CDs. Methods This retrospective analysis included commercially insured or Medicare Advantage male and female members aged 50 years or older with medical and pharmacy benefits who had evidence of osteoporosis and/or one of the CDs during the identification period (January 1, 2007, to October 31, 2009). Cohorts were defined by the presence or absence of osteoporosis and CD (osteoporosis ONLY, CD ONLY, and CD plus osteoporosis) and, for osteoporosis cohorts, by incident (recent diagnosis) or prevalent osteoporosis (long-standing). Primary outcome was total health care costs during 1-year follow-up. Costs, adjusted for baseline characteristics, were analyzed with a generalized linear model with log link and gamma distribution. Results Of the 494,160 patients, the majority had evidence of CD with or without osteoporosis: CVD (54%), two or more CDs (24%), DM (8%), depression (4%), COPD (1%); 9% had osteoporosis ONLY. The range of actual mean costs was as follows: CD ONLY, $8,377 (CVD) to $12,801 (two or more CDs); CD plus incident osteoporosis, $15,696 (CVD) to $23,860 (two or more CDs); CD plus prevalent osteoporosis, $10,038 (CVD) to $17,997 (two or more CDs). Compared with CD ONLY, baseline-adjusted costs were 66% (two or more CDs) to 91% (DM) higher for CD plus incident osteoporosis and 13% (CVD) to 23% (depression) higher for CD plus prevalent osteoporosis ( P Conclusions The burden of osteoporosis in patients with CD is significant, particularly for patients with newly diagnosed osteoporosis.

Two previous retrospective database analyses compared early combination therapy with an α-blocker (AB) and 5-α reductase inhibitor (5-ARI) to delayed combination therapy and found that patients receiving the delayed combination therapy were more likely to have clinical progression, acute urinary retention (AUR), and surgery. Although these studies indicate the clinical benefits of early treatment, both studies failed to take into account important baseline clinical measures, such as prostate-specific antigen (PSA) values.This study was designed to compare clinical and cost differences in men with benign prostatic hyperplasia (BPH) who initiated early versus delayed combination therapy with a 5-ARI + an AB, factoring in baseline PSA values.This retrospective claims data analysis assessed data from14 million US men with linked medical data, pharmacy data, laboratory results, and enrollment information from January 1, 2000, to December 31, 2009. Men aged 50 or older and treated for BPH with a 5-ARI + an AB were identified. Patients were required to be eligible for services at least 6 months before and 12 months after the index medication date. Patients were assigned to 1 of 2 treatment groups based on therapy (early or delayed) and 3 cohorts based on availability of PSA laboratory values (patients with a PSA value, patients with a PSA value1.5 and10, and all patients). Using a logistic model, the likelihood of clinical progression (defined as the occurrence of AUR or prostate surgery) during the 12 months after the date of first prescription fill was compared between BPH patients receiving early versus delayed combination therapy. BPH-related medical costs (excluding pharmacy costs) were assessed using generalized linear models.Among the 13,551 patients identified for study inclusion, the highest risks for clinical progression, AUR, and prostate-related surgery were consistently demonstrated in patients with a PSA1.5 and10. Across all 3 cohorts, the delayed combination-treatment group was more likely to have clinical progression, AUR, and prostate-related surgeries versus the early combination-treatment group. The incremental difference in BPH-related costs between the delayed and early combination-treatment groups was $190 per patient overall; the greatest incremental difference ($397) was observed in patients with PSA1.5 and10.The results suggest that early initiation of combination therapy with 5-ARI + an AB, compared with delayed initiation, can reduce the risks for clinical progression, AUR, and prostate-related surgeries, as well as BPH-related medical costs, in patients with BPH.

Background Community-acquired pneumonia (CAP) causes substantial clinical and economic burden. While several studies have reported the cost to treat CAP, there is little information on the cost to treat by age, risk profile, and hospitalization in US adults aged ≥50 years. Objective To quantify the cost, from a payer perspective, of treating CAP at the episode level, stratified by age, risk profile, and hospitalization. Methods A retrospective study of claims data from a large US health plan (1 January 2006–31 December 2008) was conducted. Patients aged ≥50 years having at least one medical claim with a primary diagnosis for pneumonia were identified. A CAP episode was defined as the period between the first and last pneumonia ICD-9 code with a chest X-ray claim. Episode-level variables included risk stratum based on presence of an immunocompromising/chronic condition, age group, number and length of inpatient and outpatient CAP episodes, and all-cause and CAP-related healthcare costs (adjusted to 2011 costs). Results Among the 27,659 study patients, 28,575 CAP episodes (20,454 outpatient; 8,121 inpatient) occurred. Mean age of patients with a CAP episode was 62.6. Low-risk patients accounted for 44.4 % of all CAP episodes. Mean CAP episode length was 31.8 days for an inpatient episode and 10.2 days for an outpatient episode. Mean all-cause total healthcare cost for an inpatient CAP episode ranged from $11,148 to $51,219 depending on risk stratum and age group. Mean outpatient episode-related costs were much lower than inpatient episode-related costs. Conclusions Cost to treat CAP requiring hospitalization is high regardless of age or the presence of underlying comorbidities. Given that almost half of the patients in this study did not have traditional risk factors for CAP, it is clear that better preventative strategies are needed.

New or recurrent stroke was based on history in the previous 12 months, with index date defined as first date of ­indication of stroke. A control group without stroke or transient ischemic attack (TIA) was matched (1:3) on age, sex, and geographic region, with an index date defined as the first ­medical claim during the patient identification period. Patients with atrial fibrillation or mitral value abnormalities were excluded. Ischemic stroke and control cohorts were compared on 4-year clinical outcomes and 1-year costs.Results: Of 2180 ischemic stroke patients, 1808 (82.9%) had new stroke and 372 (17.1%) had a recurrent stroke. Stroke patients had higher unadjusted rates of additional stroke, TIA, and fatal outcomes compared with the 6540 matched controls. Recurrent stroke patients had higher rates of adverse clinical outcomes compared with new stroke patients; costs attributed to recurrent stroke were also higher. Stroke patients were 2.4 times more likely to be hospitalized in follow-up compared with controls (hazard ratio [HR] 2.4, 95% confidence interval [CI]: 2.2, 2.6). Occurrence of stroke following discharge was 21 times more likely among patients with index stroke compared with controls (HR 21.0, 95% CI: 16.1, 27.3). Stroke was also predictive of death (HR 1.8, 95% CI: 1.3, 2.5). Controlling for covariates, stroke patients had significantly higher costs compared with control patients in the year following the index event.Conclusion: Noncardioembolic ischemic stroke patients had significantly poorer outcomes and higher costs compared with controls. Recurrent stroke appears to contribute substantially to these higher rates of adverse outcomes and costs.Keywords: burden of illness, stroke⁄cerebrovascular accident, cardiovascular disease, claims analysis, costs of care, health care outcomes

To identify the relationship between resource utilization and treatment of asthma in subjects who were first time users of controller therapies, either fluticasone propionate (FP) and salmeterol delivered in a single Diskus device (FSC) or FP monotherapy.A retrospective, observational cohort analysis evaluated pharmacy and medical claims from subjects from a commercial managed-care database, which is similar in makeup to the US privately insured population, with a diagnosis of asthma and ≥1 prescription for FSC or FP dispensed from 1/1/2001 to 4/30/2005. Outcomes of interest were asthma-related emergency department (ED) visits, inpatient (IP) visits, and a combined outcome (IP or ED visits). Predicted rates of asthma-related and all-cause intubations were also reported for each cohort. Multivariate analysis of events was conducted using logistic regression and Cox proportional hazard regression. All outcomes were adjusted for differences in baseline characteristics.There were 58 270 subjects identified (FSC, n = 42 466; FP, n = 15 804). Mean age was 37.65 years and 35.75% was female. The use of FSC was associated with lower risk of having an asthma-related ED visit (adjusted OR 0.79; 95% CI, 0.72-0.87) and an asthma-related ED/IP visit (OR 0.80; 95% CI, 0.73-0.88). Asthma-related ED and ED/IP rates were also significantly lower for FSC than for FP. There were no differences observed in post-index asthma-related intubations rates.In this observational study using a large managed-care database, subjects treated with FSC were at significantly less risk for developing serious asthma exacerbations and had lower resource utilization than a cohort of subjects treated with FP. This is clinically meaningful despite the inherent limitations of these types of observational studies.

164 Background: National Comprehensive Cancer Network breast cancer guidelines suggest sequencing of systemic therapy. This study examined sequencing of endocrine and chemotherapy treatments to better understand real-world treatment patterns for HR+/HER2- advanced breast cancer. Methods: A proprietary clinical cancer database with physician-reported clinical data on patients with breast cancer was linked to medical and pharmacy claims (2008-2012) from a national US health plan. Study patients had HR+ and HER2- status. Advanced cancer cohorts were defined: stage III (SIII) or IV (SIV) at initial diagnosis, or developed metastases following initial diagnosis (MET). Index date was the first date of advanced cancer diagnosis or date of metastases following initial diagnosis. Health plan enrollment for 3 months pre- and ≥ 3-months post- index date was required; patients who died within 3 months after index date and were continuously enrolled were retained. A 3-month baseline period assessed prior treatment; a variable follow-up (until disenrollment or 31 Oct 2012) assessed patterns of endocrine and chemotherapy treatments following index date. Results: A total of 954 breast cancer patients met study inclusion criteria and were HR+/HER2- with ≥ 3 months of continuous enrollment after index date, with 369 of the 954 (38.68%) SIII, 117 (12.26%) SIV, and 469 (49.16%) MET patients. In the study population, 83.65% were treated with endocrine therapy, starting an average of 179 days after index date. A total of 80.29% were treated with chemotherapy, starting an average of 53 days following the index date; 65% of patients initiated chemotherapy after index date without prior endocrine treatment. Rates varied by cohort: 90% of SIII, 57% of SIV, and 48% of MET patients had no evidence of endocrine treatment prior to initiating chemotherapy. Conclusions: This study found large proportions of HR+/HER2- advanced breast cancer patients initiated chemotherapy without prior endocrine therapy. Further investigation of patient characteristics and outcomes by therapy sequencing patterns will help illuminate the extent to which patterns adhere to NCCN guidelines.

There are 10 million patients with angina in the United States (500,000 new diagnoses annually). Although clinical efficacy of angina treatments is understood, total costs of care and clinical outcomes for patients with chronic angina in different treatment protocols are unknown.Our objective was to estimate total costs of care and revascularization rates for patients with poorly controlled angina who added either (1) long-acting nitrates, (2) beta blockers or calcium channel blockers, or (3) ranolazine to their therapy.We performed retrospective claims analysis using an index event involving change of therapy in which a new antiangina drug was added.Using a large commercial insurance claims database, 4545 patients with angina with an index event (ie, change of antiangina therapy) and 6 months of continuous enrollment pre- and postindex event were identified. Using total cost of care and revascularization rates, we first compared preindex disease burden, medical care use, and total cost of care and components of total cost. We then compared unadjusted use and cost of care across treatment groups. Finally, we estimated regression models to predict postindex event total costs of care and revascularization rates.During the preindex period, the 3 comparison groups had similar health measures, medical care use, and total costs of care. During the postindex period, ranolazine users had lower revascularization rates (9.9%) than comparison patient groups (15.4%-20.4%, both Ps0.001). Ranolazine users had lower total costs of care ($13,961) than the nitrate group ($18,166, 30.0% higher; P0.001) and the beta blockers/calcium channel blockers group ($17,612, 26.6% higher; P = 0.002).Adding ranolazine to the treatment regimen of patients with poorly controlled angina was associated with lower rates of revascularization and lower total costs of care than for comparable patients, differences both statistically and clinically relevant.

SummaryBackgroundPatients who have asthma-related emergency department (ED) visits or hospitalizations are at risk for recurrent exacerbation events. Our objectives were to assess whether receiving a controller medication at discharge affects risk of recurrence and whether delaying controller initiation alters this risk.MethodsAsthma patients with an ED visit or inpatient (IP) stay who received a controller dispensing within 6 months were identified from healthcare claims. Cox proportional hazards of the time to first recurrence of an asthma-related ED or IP visit in the 6-month period following the initial event were constructed, with time following discharge without controller medication as the primary predictor.ResultsA total of 6139 patients met inclusion criteria, 78% with an ED visit and 22% with an IP visit; 15% had a recurrence within 6 months. The adjusted hazard ratio (HR) associated with not having controller medication at discharge was 1.79 (95% confidence interval [CI], 1.42–2.25). The controller-by-time interaction was significant (P
