Dyslipidemia treatment of patients with diabetes mellitus in a US managed care plan: a retrospective database analysis
<p>Abstract</p> <p>Background</p> <p>To evaluate real-world pharmacologic treatment of mixed dyslipidemia in patients with diabetes mellitus (DM).</p> <p>Methods</p> <p>All commercial health plan members in a large US managed care database with complete lipid panel results (HDL-C, LDL-C, TG) between 1/1/2006 and 12/31/2006 were identified (N = 529,236). DM patients (N = 53,679) with mixed dyslipidemia were defined as having any 2 suboptimal lipid parameters (N = 28,728). Lipid treatment status 6 months pre- and post-index date was determined using pharmacy claims for any lipid therapy.</p> <p>Results</p> <p>Post-index, 41.1% of DM patients with 2 abnormal lipid parameters and 45.1% with 3 abnormal lipid parameters did not receive lipid-modifying treatment. Post-index treatment rates were 57.4%, 63.6%, and 66.4% for patients with LDL-C, HDL-C, and TG in the most severe quartiles, respectively. Statin monotherapy was the primary lipid-modifying regimen prescribed (54.8% and 47.8% of patients with any 2 and all 3 lipids not at goal, respectively). Less than 30% of treated patients received combination therapy.</p> <p>Conclusion</p> <p>Over 40% of DM patients with mixed dyslipidemia received no lipid-modifying therapy during the follow-up period. Those who were treated were primarily prescribed statin monotherapy. This study suggests that DM patients are not being treated to ADA-suggested targets.</p
GERD-Related Health Care Utilization, Therapy, and Reasons for Transfer of GERD Patients Between Primary Care Providers and Gastroenterologists in a US Managed Care Setting
Mortality associated with gastrointestinal bleeding events: Comparing short-term clinical outcomes of patients hospitalized for upper GI bleeding and acute myocardial infarction in a US managed care setting
C Mel Wilcox1, Byron L Cryer2, Henry J Henk3, Victoria Zarotsky3, Gergana Zlateva41University of Alabama, Birmingham, AL, USA; 2University of Texas Southwestern Medical School, Dallas, TX; 3i3 Innovus, Eden Prairie, MN, USA; 4Pfizer, Inc., New York, NY, USA Objectives: To compare the short-term mortality rates of gastrointestinal (GI) bleeding to those of acute myocardial infarction (AMI) by estimating the 30-, 60-, and 90-day mortality among hospitalized patients.Methods: United States national health plan claims data (1999&ndash;2003) were used to identify patients hospitalized with a GI bleeding event. Patients were propensity-matched to AMI patients with no evidence of GI bleed from the same US health plan.Results: 12,437 upper GI-bleed patients and 22,847 AMI patients were identified. Propensity score matching yielded 6,923 matched pairs. Matched cohorts were found to have a similar Charlson Comorbidity Index score and to be similar on nearly all utilization and cost measures (excepting emergency room costs). A comparison of outcomes among the matched cohorts found that AMI patients had higher rates of 30-day mortality (4.35% vs 2.54%; p&nbsp;&lt; 0.0001) and rehospitalization (2.56% vs 1.79%; p = 0.002), while GI bleed patients were more likely to have a repeat procedure (72.38% vs 44.95%; p&nbsp;&lt; 0.001) following their initial hospitalization. The majority of the difference in overall 30-day mortality between GI bleed and AMI patients was accounted for by mortality during the initial hospitalization (1.91% vs 3.58%).Conclusions: GI bleeding events result in significant mortality similar to that of an AMI after adjusting for the initial hospitalization.Keywords: gastrointestinal, bleeding, mortality, acute myocardial infarction, claims analysi
Chronic kidney disease in gout in a managed care setting
<p>Abstract</p> <p>Background</p> <p>To study the prevalence of chronic kidney disease (CKD) and its impact on allopurinol dosing and uric acid control among patients with gout.</p> <p>Methods</p> <p>This was a retrospective study using data from a large US health plan. Claims and laboratory data were analyzed for enrollees from the health plan database from January 2002 through December 2005. Patients with gout were identified from pharmacy and medical claims data based on the presence of codes for gout medication or gout diagnosis. Severity of CKD was determined using the estimated glomerular filtration rate (eGFR). Allopurinol titration was defined as a change in average daily dose from first prescription to last prescription of ≥ 50 mg.</p> <p>Results</p> <p>A total of 3,929 patients were identified for inclusion in this study, 39% of whom had CKD (based on having an eGFR < 90 mL/min/1.73 m<sup>2</sup>). Subjects with CKD were older (p < 0.01) and more likely to be women (p < 0.01), had a greater number of comorbid conditions (p < 0.01), and were more likely to be prescribed allopurinol (p < 0.01) compared to those with no CKD. The average starting dose of allopurinol was lower among those with CKD, and it decreased with worsening kidney function. Among the 3,122 gout patients who used allopurinol, only 25.6% without CKD and 22.2% with CKD achieved a serum uric acid concentration of < 6.0 mg/dL (p = 0.0409). Also, only 15% of allopurinol users had an upward dose titration (by ≥50 mg), but the average increase in dose did not differ significantly between those with and without CKD.</p> <p>Conclusions</p> <p>About two out of every five patients with gout in this population had CKD. Allopurinol doses were not adjusted in the majority of CKD patients. Serum uric acid control in gout was poor among patients without CKD and even worse among those with CKD.</p
