Real-world outcomes among patients with early rapidly progressive rheumatoid arthritis.

OBJECTIVES: To characterize treatment patterns, healthcare resource utilization (HRU), and disease activity among patients with early rapidly progressive rheumatoid arthritis (eRPRA) in the United States when treated with a first-line biologic disease-modifying antirheumatic drug (bDMARD) tumor necrosis factor-α (TNF) inhibitor or first-line abatacept. STUDY DESIGN: Observational, multicenter, retrospective, longitudinal, medical records-based, cohort study. METHODS: Patients with eRPRA were identified by anti-citrullinated protein antibody positivity, 28-joint Disease Activity Score-C-reactive protein of 3.2 or greater, symptomatic synovitis in 2 or more joints for at least 8 weeks prior to the index date, and onset of symptoms within 2 years or less of the index date. Patients received abatacept or a TNF inhibitor as first-line treatment. Patient characteristics, treatment patterns, HRU, and disease activity following bDMARD initiation were compared across the 2 groups. Odds ratios (ORs) of HRU in the first 6 months of bDMARD treatment were estimated using multivariable logistic regression to adjust for patient mix. RESULTS: There were 60 patients treated with abatacept and 192 treated with a TNF inhibitor in the first line. Those treated with first-line abatacept had lower adjusted odds of hospitalization (OR, 0.42; 95% CI, 0.18-0.95), emergency department (ED) visits (OR, 0.39; 95% CI, 0.16-0.93), and magnetic resonance imaging (MRI) (OR, 0.45; 95% CI, 0.21-0.97) than those treated with a first-line TNF inhibitor (all P <.05). Adjusted odds of achieving low disease activity as measured by clinical disease activity index within 100 days of bDMARD initiation favored first-line abatacept versus a first-line TNF inhibitor (OR, 4.37; 95% CI, 1.34-13.94; P = .01). CONCLUSIONS: Adjusting for disease severity, patients with eRPRA who were treated with first-line abatacept were less likely to have hospitalizations, ED visits, and MRI use during the first 6 months of bDMARD treatment and more likely to achieve low disease activity within 100 days of bDMARD start compared with those who received a first-line TNF inhibitor.

Comparative treatment patterns, healthcare resource utilization and costs of atomoxetine and long-acting methylphenidate among children and adolescents with attention-deficit/hyperactivity disorder in Germany.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) imposes a substantial burden on patients and their families. OBJECTIVE: A retrospective, propensity score-matched cohort study compared treatment patterns, healthcare resource utilization (HRU) and costs among children/adolescents with ADHD aged 6-17 years at treatment initiation (index) in Germany who received atomoxetine (ATX) or long-acting methylphenidate (LA-MPH) monotherapy. METHODS: Patients received at least one prescription for their index medication (ATX/LA-MPH) during 2006-2010; the first prescription marked the index date. ATX- and LA-MPH-indexed cohorts were matched 1:1 (n = 737); a patient subset was identified that had not received ADHD-indicated medications in 12 months prior to index (novel initiators: ATX, n = 486; LA-MPH, n = 488). Treatment patterns were evaluated among novel initiators, and HRU and costs among the matched cohorts in the 12 months after index. RESULTS: No significant differences in baseline characteristics were found between the novel initiator patient subsets. ATX-indexed novel initiators had significantly longer persistence to index medication [mean (standard deviation; SD) days: 222.0 (133.9) vs 203.2 (135.0), P = 0.029) but higher switching rates (8.8 vs 5.5 %, P = 0.045) than LA-MPH-indexed novel initiators. The total ATX-indexed cohort required more prescriptions [any medication; mean (SD): 20.9 (11.5) vs 15.7 (9.0), P < 0.001] and outpatient visits [mean (SD): 10.1 (6.3) vs 8.3 (5.3), P < 0.001], and incurred significantly higher total median healthcare costs (€1144 vs €541, P < 0.001) versus matched LA-MPH patients. CONCLUSIONS: These real-world data indicate that, among children/adolescents with ADHD in Germany, ATX-indexed patients may require more prescriptions and physician visits, and incur higher total healthcare costs, than matched LA-MPH patients.

Development and initial validation of a self-scored COPD Population Screener Questionnaire (COPD-PS).

COPD has a profound impact on daily life, yet remains underdiagnosed and undertreated. We set out to develop a brief, reliable, self-scored questionnaire to identify individuals likely to have COPD. COPD-PS development began with a list of concepts identified for inclusion using expert opinion from a clinician working group comprised of pulmonologists (n = 5) and primary care clinicians (n = 5). A national survey of 697 patients was conducted at 12 practitioner sites. Logistic regression identified items discriminating between patients with and without fixed airflow obstruction (AO, postbronchodilator FEV(1)/FVC < 70%). ROC analyses evaluated screening accuracy, compared scoring options, and assessed concurrent validity. Convergent and discriminant validity were assessed via COPD-PS and SF-12v2 score correlations. For known-groups validation, COPD-PS differences between clinical groups were tested. Test-retest reliability was evaluated in a 20% sample. Of 697 patients surveyed, 295 patients met expert review criteria for spirometry performance; 38% of these (n = 113) had results indicating AO. Five items positively predicted AO (p < 0.0001): breathlessness, productive cough, activity limitation, smoking history, and age. COPD-PS scores accurately classified AO status (area under ROC curve = 0.81) and reliable (r = 0.91). Patients with spirometry indicative of AO scored significantly higher (6.8, SD = 1.9; p< 0.0001) than patients without AO (4.0, SD = 2.3). Higher scores were associated with more severe AO, bronchodilator use, and overnight hospitalization for breathing problems. With the prevalence of COPD in the studied cohort, a score on the COPD-PS of greater than five was associated with a positive predictive value of 56.8% and negative predictive value of 86.4%. The COPD-PS accurately classified physician-reported COPD (AUC = 0.89). The COPD-PS is a brief, accurate questionnaire that can identify individuals likely to have COPD.

Identifying patients with benign prostatic hyperplasia through a diagnosis of, or treatment for, erectile dysfunction.

OBJECTIVE: Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) associated with benign prostate hyperplasia (BPH) are highly correlated. This study examined rates of screening, diagnosis, and treatment of BPH/LUTS among men seeking care for ED. RESEARCH DESIGN AND METHODS: This was a retrospective US claims data analysis (1999-2004) evaluating men > or = 40 years old with a new diagnosis of or prescription medication for ED. Multivariate analyses were used to examine times to screening, diagnosis, and treatment. RESULTS: 81 659 men with ED were identified (mean age 57 years). The baseline prevalence of recorded BPH was 1.5%. During the follow-up period (mean 2.2 years), 7.6% had documented BPH. Time to screening was shorter among patients seeing urologists (121.1 days) compared with those seeing primary-care physicians (282.2 days). Controlling for demographic and clinical characteristics, patients who saw a urologist were more likely to be screened (OR: 2.4, p < 0.0001), diagnosed with BPH (OR: 1.8, p < 0.0001), and treated (OR: 1.3, p < 0.0001), relative to patients seeing other providers. Men aged 75 and over were 43% less likely to be screened (p < 0.0001), but 5.4 times more likely to be diagnosed with BPH (p < 0.0001) and 5.3 times more likely to be treated (p < 0.0001) compared with men aged 40-49. CONCLUSIONS: Screening for BPH appears less likely for men with ED who do not see a urologist. When screening does occur, it takes much longer with non-specialty providers. Patient age and provider specialty are key factors associated with screening, diagnosis, and treatment of BPH among men with ED.

The prevalence, burden, and treatment of urinary incontinence among women in a managed care plan.

OBJECTIVE: Urinary incontinence (UI) symptoms are common among women, yet only a small proportion of women with incontinence receive a diagnosis and treatment. We used survey and utilization data to determine the prevalence, burden, and treatment use for incontinence among women at Kaiser Permanente in Northern California. METHODS: In 2002, we surveyed 6726 female health plan members about health issues, including incontinence. We assessed type and bothersomeness of incontinence symptoms in the previous 7 days. For survey respondents and a 10% sample of female plan members (n = 108,825), we assessed use from 1997 to 2003. RESULTS: The survey response rate was 49.7% (3344 of 6726); 44% of respondents reported incontinence symptoms in the previous 7 days, with over half of these women reporting that these symptoms bothered them. Fifteen percent of women with incontinence symptoms had a diagnosis consistent with incontinence in the previous 5 years. One third of the women reporting current bothersome incontinence and 14 or more incontinence episodes in the last 7 days had a diagnosis consistent with incontinence in the previous 5 years. Among women who had received medical or surgical treatment for incontinence in the previous 5 years, approximately half currently report being bothered by their symptoms. CONCLUSIONS: Prevalence of bothersome incontinence symptoms among females in a prepaid health plan is high. However, only a small proportion of these women received a diagnosis or treatment for incontinence symptoms in the last 5 years. Efforts to improve the detection and treatment of bothersome incontinence symptoms are needed.

Comparison of health care costs and co-morbidities between men diagnosed with benign prostatic hyperplasia and cardiovascular disease (CVD) and men with CVD alone in a US commercial population.

OBJECTIVE: The purpose of this study was to compare costs and treatment patterns between men with concomitant benign prostatic hyperplasia (BPH) and CVD to men with CVD (but not BPH). STUDY DESIGN: A retrospective, matched cohort study was utilized to assess costs and treatment between two study populations. METHODS: The data source was administrative claims from managed care organizations between January 1, 1997 and December 31, 2004. A control group of men with CVD only was created matching by age, index CVD diagnosis date, and CVD diagnoses. Diagnosis and procedure codes identified men with BPH and CVD. Differences in medical costs, co-morbidities, and drug treatments were assessed. RESULTS: Approximately 39% of men identified with BPH also had some form of CVD at the time of BPH diagnosis. Men with BPH and CVD were more likely to have additional co-morbidities, more frequently received medications for CVD and non-CVD disorders, had 44% higher total medical costs than men with CVD only (p < 0.001), and had 42% higher CVD-related costs (p < 0.001) than men with CVD only. LIMITATIONS: The population studied in this analysis was primarily working individuals with health benefits provided by managed care plans; therefore, the results may not generalize to other populations. CONCLUSIONS: This study demonstrates in a commercial payer population that men with concomitant BPH and CVD have more co-morbidities, receive pharmacologic agents more frequently, and have higher health care resource utilization than men with CVD only. Due to the high prevalence of co-morbid BPH and CVD, screening for BPH in men presenting with CVD may assist with earlier disease identification and cost management over time.
