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.

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

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
