Patient and physician perspectives guiding intra-articular treatment choice in knee osteoarthritis: stakeholders are aligned on treatment priorities but have different assessments of treatment effect.

OBJECTIVES: Knee osteoarthritis (OA) is a leading cause of health-related disability. In the absence of curative non-operative therapies, treatment goals are limited to symptom relief. Data are limited on how patients and physicians prioritise available treatment options. We assessed patients' preferences for and physicians' attitudes towards intra-articular treatments including corticosteroids (IACS), an extended-release corticosteroid (TA-ER) and hyaluronic acids (IAHA). METHODS: We conducted a prospective, IRB-exempt, double-blind survey of patients with and providers who treat knee OA. Respondents were required to have received or prescribed TA-ER in a non-trial setting. We evaluated patients' OA history, impact of knee OA and treatment preferences, and physicians' decision-making and prescribing experiences. RESULTS: Of the 97 patient participants, mean age was 56 years, 70.0% were women, 75.0% had bilateral knee OA and 46.4% were diagnosed over 5 years ago. Of the 50 physician participants, 42.0% were orthopaedic surgeons, 34.0% were rheumatologists and 60.0%, on average, treat 50+ patients with knee OA per month. Treatment selection factors considered 'very important' to patients and physicians included disease severity (88.7%, 82.0%), impact on quality of life (88.7%, 72.0%), disease extent (84.5%, 54.0%) and activity level (80.4%, 64.0%). A majority (93.8%) of patients indicated moderate to severe difficulty with their knees. Fewer patients (76.3%) reported shared decision making compared with physicians (92.0%). Half (50.5%) of the patients reported that they experienced months of pain relief with TA-ER, 27.7% with IACS and 18.8% with IAHA. Physician assessments were consistent but estimated a greater duration of treatment effects than that reported by patients across all therapies. CONCLUSION: While knee OA has a tremendous impact on patients, there are significant unmet treatment needs. The increasing use of patient-reported outcomes will allow patients and physicians to track pain and functional status over time and across therapies, improving shared decision-making.

Clinical and Economic Outcomes in Patients with Persistent Asthma Who Attain Healthcare Effectiveness and Data Information Set Measures.

BACKGROUND: Attainment of asthma-specific US Healthcare Effectiveness Data and Information Set (HEDIS) quality measures may be associated with improved clinical outcomes and reduced economic burden. OBJECTIVE: We examined the relationship between the attainment of HEDIS measures asthma medication ratio (AMR) and medication management for people with asthma (MMA) on clinical and economic outcomes. METHODS: This retrospective claims database analysis linked to ambulatory electronic medical records enrolled US patients aged ≥5 years with persistent asthma between May 2015 and April 2017. The attainment of AMR ≥0.5 and MMA ≥75% was determined over a 1-year premeasurement period. Asthma exacerbations and asthma-related health care costs were evaluated during the subsequent 12-month measurement period, comparing patients attaining 1 or both measures with those not attaining either. RESULTS: In total, 32,748 patients were included, 75.2% of whom attained AMR (n = 24,388) and/or MMA (n = 12,042) during the premeasurement period. Fewer attainers of 1 or more HEDIS measures had ≥1 asthma-related hospitalizations, emergency department visit, corticosteroid burst, or exacerbation (4.9% vs 7.3%; 9.6% vs 18.2%; 43.8% vs 51.6%; 14.3% vs 23.3%, respectively; all P < .001) compared with nonattainers. In adjusted analyses, HEDIS attainment was associated with a lower likelihood of exacerbations (odds ratio: 0.63, [95% confidence interval: 0.60-0.67]; P < .001). The attainment of ≥1 HEDIS measures lowered total and asthma-related costs, and asthma exacerbation-related health care costs per patient relative to nonattainers (cost ratio: 0.87, P < .001; 0.96, P = .02; and 0.59, P < .001, respectively). Overall and asthma-specific costs were lower for patients attaining AMR, but not MMA. CONCLUSIONS: HEDIS attainment was associated with significantly improved asthma outcomes and lower asthma-specific costs.

Analysis of Real-World Dosing Patterns for the 3 FDA-Approved Medications in the Treatment of Fibromyalgia.

BACKGROUND: Fibromyalgia is a chronic condition characterized by widespread pain, fatigue, and sleep disturbances that affects approximately 2% to 4% of the adult population in the United States, with minimal real-world data related to the use of medications and associated dosages for this condition. OBJECTIVE: To analyze the real-world dosing patterns of the 3 medications approved by the US Food and Drug Administration for fibromyalgia-pregabalin, duloxetine, and milnacipran. METHODS: Using QuintilesIMS' (now IQVIA) electronic medical record data linked to administrative claims, we identified adults with fibromyalgia who were newly prescribed pregabalin, duloxetine, or milnacipran between January 1, 2006, and December 31, 2014. We summarized and compared the starting and maximum doses with United States prescribing information (USPI) dosing recommendations. RESULTS: In all, 1043 patients who were receiving pregabalin, 1281 receiving duloxetine, and 326 patients receiving milnacipran with similar age and comorbidity profiles were included in the study. The mean starting dose was 176 mg daily, 56 mg daily, and 95 mg daily for pregabalin, duloxetine, and milnacipran, respectively. More patients receiving pregabalin (35%) had a starting dose lower than recommended compared with patients receiving duloxetine (7%) or milnacipran (17%; P <.0001). Of the patients who received pregabalin, 27% had USPI-recommended maintenance dosing versus 91% of patients who received duloxetine and 80% who received milnacipran (P <.0001). The mean duration of treatment was longer for duloxetine (205 days; P <.0001) than for pregabalin (167 days) and milnacipran (167 days). The duration of using the maximum dose of each medication as a percentage of the total time of medication use was 77% for pregabalin, 84% for duloxetine, and 90% for milnacipran (P <.0001). CONCLUSIONS: Patients using pregabalin were the most likely of the 3 cohorts to receive lower than label-recommended starting doses and the least likely to receive the recommended maintenance doses during follow-up compared with those receiving duloxetine or milnacipran. Real-world prescribing patterns indicate that factors other than label recommendations may be influencing prescribed dosing.

Comparative effectiveness of uterine fibroids procedures using linked medical record and claims data.

AIMS: To compare durability of uterus-conserving procedures for symptomatic fibroids in terms of incidence and time to subsequent procedures. PATIENTS & METHODS: We conducted a retrospective database study of 2648 patients having a uterus-conserving procedure for uterine fibroids from 2005 to 2011 with a minimum of 2 years follow-up. RESULTS: Patients with myomectomy or uterine artery embolization as their index procedure had lower risk of a subsequent procedure during the study compared with patients who underwent endometrial ablation. CONCLUSION: While subject to known limitations of using electronic medical record and administrative claims data, this research provides additional evidence regarding expectations for time to subsequent procedures that may be helpful for women and their healthcare providers to consider when making treatment choices.

One-year follow-up healthcare costs of patients hospitalized for transient ischemic attack or ischemic stroke and discharged with aspirin plus extended-release dipyridamole or clopidogrel.

OBJECTIVE: To examine healthcare costs among patients hospitalized for transient ischemic attack or ischemic stroke (TIA/stroke) and prescribed aspirin plus extended-release dipyridamole (ASA-ERDP) or clopidogrel (CLOPID) within 30 days post-discharge using a retrospective claims database from a large US managed care organization. METHODS: Adult patients with ≥1 hospitalizations for TIA/stroke between January 2007-July 2009 and ≥1 claims for an oral anti-platelet (OAP) were observed for 1 year before and after the first TIA/stroke hospitalization or until death, whichever came first. Cohorts were defined by the first claim for ASA-ERDP or CLOPID within 30 days post-discharge. A generalized linear model, adjusting for demographics, baseline comorbidities and costs, compared total follow-up costs (medical + pharmacy) between ASA-ERDP and CLOPID patients. RESULTS: Of 6377 patients (2085 ASA-ERDP; 4292 CLOPID) who met the selection criteria, mean (SD) age was 69 (13) years and 50% were male. Unadjusted mean total follow-up costs were lower for ASA-ERDP than CLOPID ($26,201 vs $30,349; p=0.002), of which average unadjusted medical and pharmacy costs were $22,094 vs $26,062 (p=0.003) and $4107 vs $4288 (p=0.119), respectively. Multivariate modeling indicated that the following were associated with higher total costs (all p<0.05): higher baseline Quan-Charlson comorbidity score, history of atrial fibrillation and myocardial infarction, index stroke hospitalization, death post-discharge, and index CLOPID use. Adjusted mean total follow-up costs for CLOPID were 9% higher than ASA-ERDP (cost ratio: 1.09; p=0.038). CONCLUSION: In this study, compared to CLOPID patients, ASA-ERDP patients were observed to have lower total costs 1 year post-discharge TIA/stroke hospitalization, driven primarily by lower medical costs. Further research into the real-world impact of OAP therapies on clinical and economic outcomes of patients with stroke/TIA is warranted. The findings of this study should be considered within the limitations of an administrative claims analysis, as claims data are collected for the purpose of payment.

Medical care costs and survival associated with hepatocellular carcinoma among the elderly.

BACKGROUND & AIMS: We assessed the burden of hepatocellular carcinoma (HCC), in terms of mortality and medical care costs, based on analysis of the Surveillance, Epidemiology and End Results (SEER)-Medicare database. METHODS: We analyzed data from the SEER-Medicare database on patients 66 years or older who were diagnosed with primary HCC from 1991 to 2007, entitled for Medicare Parts A and B, and not enrolled in health maintenance organizations (n = 5712). Controls were individuals without HCC, identified from a 5% sample of Medicare beneficiaries residing in SEER areas; they were matched 1:1 with individuals with HCC (cases) for age, sex, race, and geographic region (average age, 75 y; 34.7% female). Kaplan-Meier analysis was used to estimate survival distributions. Costs were reported in 2009 dollars; per-patient-per-month (PPPM) costs were compared between cases and controls using the Wilcoxon rank sum test. RESULTS: The largest proportion of cases had localized disease (38.2%), followed by regional (24.0%), unstaged (20.4%), and distant (17.3%) disease. The median survival times were 5 months for cases and 60 months for controls; they were 3 months for patients with distant disease, 4 months for patients with regional disease, and 9 months for those with localized disease. The mean PPPM costs were $7863 for cases and $1243 for controls (P < .001). These costs were primarily driven by inpatient (mean, $5439 vs $682 without HCC; P < .001) and hospice (mean $554 vs $42 without HCC; P < .001) care. Mean PPPM costs by stage were $7265 for localized disease, $8072 for regional disease, and $9585 for distant disease (P < .001 for trend). CONCLUSIONS: Based on analysis of the SEER-Medicare database, costs for patients with HCC are approximately 6- to 8-fold higher than for those without this cancer. Patients with distant HCC had the greatest costs. These findings highlight that HCC is a substantial medical cost burden for elderly patients.
