While step therapy (ST) policies are generally effective at reducing cost through the managed utilization of targeted medications, the clinical implications of ST policies are not clear and may vary across therapeutic areas. Guanfacine extended-release (GXR) is approved by the FDA for the treatment of attention-deficit/hyperactivity disorder (ADHD)...

A variety of biologic therapies are currently used for the treatment of inflammatory autoimmune diseases, including rheumatoid arthritis (RA), psoriasis (PsO), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). These diseases require long-term treatment, and information regarding the use and costs of biologic therapies can be valuable in m...
Conference Paper
Background: Retrospective database studies using US payer claims data have limitations due to lack of specific ICD-9 codes for PAH and ability to identify patient severity. Previous studies have used an algorithm which includes patients with either of two non-specific PH codes, along with a claim for an advanced drug therapy for PAH. This study att...
Article
Objective: To develop and test predictive models of diagnosed opioid abuse for commercial members enrolled with Humana Inc. Study Design: Retrospective claims data were analyzed using stepwise logistic regression to determine significant risk factors of diagnosed opioid abuse for an overall sample and a subset of prescription opioid users. The mode...
Article
To measure the prevalence of diagnosed opioid abuse and prescription opioid use in a multistate managed care organization. This retrospective claims data analysis reviewed the prevalence of diagnosed opioid abuse and the parallel prevalence of prescription opioid use in half-year intervals for commercial and Medicare members enrolled with Humana In...
Article
Growth in the number of patients with pain conditions, and the subsequent rise in prescription opioid use for treatment, has been accompanied by an increase in diagnosed opioid abuse. Understanding what drives the incremental healthcare costs of members diagnosed with prescription opioid abuse may assist in developing better screening techniques fo...
Article
Objective: To identify inefficiencies in drug and medical service utilization related to pain management in patients with osteoarthritis and chronic low back pain. Study design: This retrospective cohort study applied revised measures of pain management inefficiencies to Humana Medicare members with osteoarthritis and/or chronic low back pain....
Article
Healthcare resource utilization (HCRU) and associated costs specific to pain are a growing concern, as increasing dollar amounts are spent on pain-related conditions. Understanding which pain conditions drive the highest utilization and cost burden to the healthcare system would enable providers and payers to better target conditions to manage pain...
Article
Driving simulators provide a means to balance experimental control with ecological validity when studying autonomous advanced driver assistance systems. This paper presents methodological considerations in the development of research designed to investigate such systems. Assessment methods including driver performance as a safety measure, related e...

A goal of second language (L2) learning is to enable learners to understand and speak L2 words without mediation through the first language (L1). However, psycholinguistic research suggests that lexical candidates are routinely activated in L1 when words in L2 are processed. In this article we describe two experiments that examined the acquisition...
Article
During early stages of second language acquisition adult learners make frequent errors of lexical form. An experiment was performed to examine this effect in the laboratory. More and less fluent bilinguals in English and Spanish performed a translation recognition task in which they decided whether the second of two words was the correct translatio...

A categorization paradigm was used to investigate the relations between lexical and conceptual connections in bilingual memory. Fifty-one more fluent and less fluent English-French bilinguals viewed category names (e.g., vegetable) and then decided whether a target word (e.g., peas) was a member of that category. The category names and target words...
