THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2018; 19:21-35. [PMID: 28093662 PMCID: PMC5773633 DOI: 10.1007/s10198-016-0864-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2015] [Accepted: 12/08/2016] [Indexed: 06/06/2023]
Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurobehavioral disorder in children that may persist into adulthood. Lisdexamfetamine dimesylate (LDX) is approved in many countries for ADHD treatment in children, adolescents, and adults. OBJECTIVES Estimate the cost-effectiveness of LDX as a first- or second-line treatment for adults with ADHD from the United Kingdom (UK) National Health Service (NHS) perspective compared with methylphenidate extended release (MPH-ER) and atomoxetine (ATX). METHODS A 1-year decision-analytic model was developed. Health outcomes included response, non-response and inability to tolerate. Efficacy data were obtained from a mixed-treatment comparison (MTC). Response was a score of 1 or 2 on the Clinical Global Impression-Improvement scale. Tolerability was assessed by discontinuation rates due to adverse events. Utilities were identified via a systematic literature review. Health care resource use estimates were obtained via a survey of clinicians. Daily drug costs were estimated from mean doses reported in the trials used in the MTC. One-way and probabilistic sensitivity analyses (PSAs) were performed. RESULTS LDX dominated MPH-ER and ATX; reducing mean per-patient annual cost by £5 and £200, and increasing mean quality-adjusted life years (QALYs) by 0.005 and 0.009, respectively. In the PSA, the probability of cost-effectiveness for LDX vs. MPH-ER and ATX at a threshold of £20,000 per QALY was 61% and 80%, respectively. CONCLUSIONS From the perspective of the UK NHS, LDX is likely to provide a cost-effective treatment for adults with ADHD. This conclusion may be drawn with more certainty in comparison with ATX than with MPH-ER.

Abstract
OBJECTIVE Stimulants are the most common and efficacious treatment for Attention-Deficit Hyperactivity Disorder (ADHD). We examined the relationship between stimulant misuse and social factors that could be malleable to prevention among American Indian (AI) adolescents. METHOD Participants were AI students (N=3498) sampled from 33 schools in 11 states. Participants completed the American Drug and Alcohol Survey. A multilevel analytic approach was used to evaluate the effects of participant-level (level 1) variables (i.e., gender, grade, peer, school, family, stimulant prescribed by doctor) on lifetime and current simulant use to 'get high.' RESULTS Nearly 7% of our sample had been prescribed stimulants and nearly 6% of the sample reported using stimulants to get high. Age [OR=1.22; 95% CI=1.09, 1.36, p<0.001], perception of peer substance use [OR=1.19; 95% CI=1.14, 1.23, p<0.001], parental monitoring [OR=0.96; 95% CI=0.92, 1.99, p=0.04], and stimulants prescribed by a doctor [OR=8.79, 95% CI=5.86, 13.18, p<0.001] were associated with ever using stimulants to get high. Perception of peer substance use, [b=0.09, SE=0.02, p<0.001, 95%CI [0.05, 0.13], and having stimulants prescribed by a doctor, [b=0.58, SE=0.21, p=0.006, 95%CI [0.17, 0.99], were associated with frequency of past month use to get high. There was also a significant quadratic effect for parental monitoring, suggesting that low and high levels were associated with increased stimulant use. CONCLUSIONS Our results suggest a need for prevention efforts to be directed to AI youth who are prescribed stimulants.

Abstract
Lisdexamfetamine dimesylate (LDX) is the first prodrug stimulant used for the treatment of attention-deficit/hyperactivity disorder (ADHD) dosed once daily. Due to its long-acting properties, LDX remains pharmacologically inactive until an enzymatic process predominantly associated with red blood cells converts it to the active ingredient, d-amphetamine and the amino acid lysine. The efficacy of LDX over placebo has been demonstrated in several studies in adults with moderate to severe ADHD with significant improvements noted in ADHD rating scales, Clinical Global Improvement scores, and assessments of executive function, for all doses of LDX (30-70 mg daily). Lisdexamfetamine dimesylate has demonstrated efficacy at 14 hours post dose in adults and may be used as a long-acting stimulant for managing ADHD symptoms, which may extend late into the day. Lisdexamfetamine dimesylate has demonstrated a safety profile consistent with long-acting stimulants use. Relevant English language articles were identified through computerized searches of MEDLINE (PubMed and EMBASE) from 1995 to 2016 using the following search terms: lisdexamfetamine dimesylate, attention-deficit hyperactivity disorder, NRP104, and Vyvanse.

Abstract
BACKGROUND Attention deficit hyperactivity disorder (ADHD) relates to four dimensions of behavior: inattentiveness, restlessness, impulsiveness and hyperactivity. Symptoms affect multiple areas of daily life such as academic performance and social functioning. Despite the negative effects of ADHD, people diagnosed with ADHD do not necessarily regard themselves as being impaired. However, it is unclear how adults with ADHD experience and manage their symptoms. OBJECTIVES To identify and synthesize the best available evidence on how adults experience living with ADHD. INCLUSION CRITERIA TYPES OF PARTICIPANTS Adults with confirmed ADHD diagnosis. PHENOMENA OF INTEREST How adults with ADHD experience and manage the symptoms of ADHD and links between protective factors provided by relatives, friends, fellow students, mentors and colleagues. TYPES OF STUDIES Studies based on qualitative data, including, but not limited to, designs within phenomenology, grounded theory, content analysis or ethnography. SEARCH STRATEGY A three-step search strategy identified published and unpublished qualitative studies from 1990 to July 2015. METHODOLOGICAL QUALITY Studies meeting the inclusion criteria were independently assessed by two reviewers using the standardized critical appraisal instrument from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). DATA EXTRACTION Data were extracted from 10 included studies using the JBI-QARI. DATA SYNTHESIS Qualitative research findings were synthesized using the JBI-QARI. RESULTS A total of 103 findings from 10 studies were aggregated into 16 categories that were meta-synthesized into four synthesized findings: "Adults are aware of being different from others and strive to be an integrated, accepted part of the community;" "Adults with ADHD are creative and inventive;" "Adults with ADHD develop coping strategies in striving for a healthy balance in life" and "For adults with ADHD, accomplishing and organizing tasks in everyday life is a challenge but it can also be rewarding." CONCLUSION Adults with ADHD have problems stemming from ADHD symptoms in relation to interacting in social relationships, academic functioning and being part of the community at the workplace and performing work tasks; they work harder to perform tasks and strive to be accepted and to be equal members of the community.Protective factors that support their ability to manage daily life with ADHD are personal strategies such as reminders and performing tasks within a given structure. Others close to them can assist by coaching, reminding them of appointments and so on. Superiors can assist by structuring the work tasks and setting up clear rules and limits for the tasks. Medication has proven to be very useful as it leads to less hyperactivity and enhances ability to stay focused and be more organized. Finally, insight into ADHD has a positive impact on the ability to manage the consequences of ADHD.Health professionals should, when advising adults with ADHD, fundamentally see them as persons who have a problem and not as problem persons, emphasize strategies adults themselves can apply such as structuring everyday tasks and informing them about positive effects and possible side effects of medication. Policy-makers could launch campaigns targeted at employers with information about the competencies adults with ADHD possess and how employers can benefit from these by structuring work tasks. When promoting employees with ADHD, it should be to positions with more advanced hands-on functions and not positions with administrative duties.

Abstract
Prescription stimulants, including methylphenidate (e.g., Ritalin) and amphetamine compounds (e.g., dextroamphetamine; Adderall), have been approved by the U.S. Food and Drug Administration for the treatment of attention-deficit/hyperactivity disorder (ADHD) and are classified by the United States Drug Enforcement Administration as Schedule II medications because of their high potential for abuse and dependence (Drug Enforcement Administration, U.S. Department of Justice, 2015). Despite the potential health and judicial consequences, misuse of prescription stimulants, typically defined as taking stimulants without a valid prescription, or use of stimulants other than as prescribed, has become a serious problem in the United States and abroad, especially on college campuses. The purpose of the present article is to review historical information concerning prescription stimulants and to summarize the literature with respect to misuse among adults, particularly college students, including risk factors, mediators and moderators, and motivations for prescription stimulant misuse. In addition, evidence is presented concerning the question of whether prescription stimulants truly enhance cognitive functioning in individuals with and without ADHD, and the ethical and professional implications of these findings are explored. Lastly, recommendations for addressing prescription stimulant misuse and suggestions for future research are advanced. (PsycINFO Database Record

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity that cause functional impairment. Recent research indicates that symptoms persist into adulthood in the majority of cases, with prevalence estimates of approximately 5% in the school age population and 2.5%–4% in the adult population. Although students with ADHD are at greater risk for academic underachievement and psychosocial problems, increasing numbers of students with ADHD are graduating from high school and pursuing higher education. Stimulant medications are considered the first line of pharmacotherapy for individuals with ADHD, including college students. Although preliminary evidence indicates that prescription stimulants are safe and effective for college students with ADHD when used as prescribed, very few controlled studies have been conducted concerning the efficacy of prescription stimulants with college students. In addition, misuse of prescription stimulants has become a serious problem on college campuses across the US and has been recently documented in other countries as well. The purpose of the present systematic review was to investigate the efficacy of prescription stimulants for adolescents and young adults with ADHD and the nonmedical use and misuse of prescription stimulants. Results revealed that both prostimulant and stimulant medications, including lisdexamfetamine dimesylate, methylphenidate, amphetamines, and mixed-amphetamine salts, are effective at reducing ADHD symptoms in adolescents and adults with ADHD. Findings also suggest that individuals with ADHD may have higher rates of stimulant misuse than individuals without the disorder, and characteristics such as sex, race, use of illicit drugs, and academic performance are associated with misuse of stimulant medications. Results also indicate that individuals both with and without ADHD are more likely to misuse short-acting agents than long-acting agents. These findings have implications for intervention, prevention, and future research.

Abstract
OBJECTIVES The purpose of this study was to assess long-term improvement in quality of life (QOL) in adolescents with attention-deficit/hyperactivity disorder (ADHD) treated with lisdexamfetamine dimesylate (LDX). METHODS Adolescents with ADHD treated for ≥3 weeks in a 4 week, placebo-controlled study entered a 1 year, open-label study. After the 4 week dose optimization (30, 50, and 70 mg/day LDX) period, treatment was maintained for 48 additional weeks. Change from baseline (of prior study) to week 52/early termination (ET) (of open-label study) in ADHD Rating Scale IV (ADHD-RS-IV) assessed effectiveness, and the Youth QOL-Research Version (YQOL-R) assessed participant-perceived QOL. Post-hoc analyses described effectiveness and QOL for participants with self-perceived poor QOL at baseline (≥1 SD below the mean) versus all others, and for study completers versus study noncompleters. RESULTS These post-hoc analyses included 265 participants. Participants with baseline self-perceived poor QOL (n=32) versus all others (n=232) exhibited robust YQOL-R perceptual score changes (improvement) with LDX, emerging by week 28 and maintained to week 52/ET. Week 52/ET mean change score ranged from +9.8 to +17.6 for participants with baseline self-perceived poor QOL and +0.4 to +5.1 for all others; week 52/ET improvements in ADHD-RS-IV total scores were similar, regardless of baseline YQOL-R total score. At week 52/ET, study completers had greater YQOL-R improvements than did noncompleters; ADHD-RS-IV total score changes were also numerically larger at week 52/ET for completers than for noncompleters. CONCLUSION Participant-perceived QOL and ADHD symptoms improved from baseline with LDX in adolescents with ADHD; greatest improvements occurred among participants with baseline self-perceived poor QOL.

Abstract
BACKGROUND This study examined the effects of lisdexamfetamine dimesylate (LDX) on quality of life (QOL) in adults with attention-deficit/hyperactivity disorder (ADHD) and clinically significant executive function deficits (EFD). METHODS This report highlights QOL findings from a 10-week randomized placebo-controlled trial of LDX (30-70 mg/d) in adults (18-55 years) with ADHD and EFD (Behavior Rating Inventory of EF-Adult, Global Executive Composite [BRIEF-A GEC] ≥65). The primary efficacy measure was the self-reported BRIEF-A; a key secondary measure was self-reported QOL on the Adult ADHD Impact Module (AIM-A). The clinician-completed ADHD Rating Scale version IV (ADHD-RS-IV) with adult prompts and Clinical Global Impressions-Severity (CGI-S) were also employed. The Adult ADHD QoL (AAQoL) was added while the study was in progress. A post hoc analysis examined the subgroup having evaluable results from both AIM-A and AAQoL. RESULTS Of 161 randomized (placebo, 81; LDX, 80), 159 were included in the safety population. LDX improved AIM-A multi-item domain scores versus placebo; LS mean difference for Performance and Daily Functioning was 21.6 (ES, 0.93, P<.0001); Impact of Symptoms: Daily Interference was 14.9 (ES, 0.62, P<.0001); Impact of Symptoms: Bother/Concern was 13.5 (ES, 0.57, P=.0003); Relationships/Communication was 7.8 (ES, 0.31, P=.0302); Living With ADHD was 9.1 (ES, 0.79, P<.0001); and General Well-Being was 10.8 (ES, 0.70, P<.0001). AAQoL LS mean difference for total score was 21.0; for subscale: Life Productivity was 21.0; Psychological Health was 12.1; Life Outlook was 12.5; and Relationships was 7.3. In a post hoc analysis of participants with both AIM-A and AAQoL scores, AIM-A multi-item subgroup analysis scores numerically improved with LDX, with smaller difference for Impact of Symptoms: Daily Interference. The safety profile of LDX was consistent with amphetamine use in previous studies. CONCLUSIONS Overall, adults with ADHD/EFD exhibited self-reported improvement on QOL, using the AIM-A and AAQoL scales in line with medium/large ES; these improvements were paralleled by improvements in EF and ADHD symptoms. The safety profile of LDX was similar to previous studies. TRIAL REGISTRATION ClinicalTrials.gov, NCT01101022.

Abstract
OBJECTIVE To review the efficacy, safety, and abuse liability of approved treatments in adults with attention-deficit/hyperactivity disorder (ADHD), with a focus on once-daily medications. DATA SOURCES PubMed was searched for relevant studies/reviews in English from 2002 to 2011 on adult ADHD treatments. STUDY SELECTION Keywords used in the search were ADHD, adults, and treatment. Limits included only clinical trials, meta-analyses, randomized controlled trials, and reviews including adults (aged ≥ 19 years). DATA EXTRACTION Selection criteria returned 471 publications. Retrieved studies were excluded if they primarily focused on children, treatments not indicated for ADHD, or ADHD and comorbid conditions. DATA SYNTHESIS An epidemiologic survey revealed that 10.9% of adults identified with ADHD had received treatment during the prior 12 months. Treatments for ADHD in adults include pharmacologic and nonpharmacologic options. US Food and Drug Administration-approved long-acting stimulants and a nonstimulant with proven efficacy and safety profiles have been developed and include osmotic-release oral system methylphenidate hydrochloride (OROS-methylphenidate), extended-release dexmethylphenidate hydrochloride, mixed amphetamine salts extended release (MAS-XR), the nonstimulant atomoxetine hydrochloride, and the prodrug lisdexamfetamine dimesylate. Long-acting stimulants differ in formulation characteristics used to achieve extended release, with OROS-methylphenidate employing an osmotic-release technology, extended-release dexmethylphenidate hydrochloride and MAS-XR using pH-dependent beads, and lisdexamfetamine dimesylate using prodrug technology. These features variably affect pharmacokinetic characteristics, duration of action, and abuse liability. While all long-acting medications have varied pharmacokinetic features, mechanism of action, and duration of effect, all are generally efficacious and safety profiles are similar. CONCLUSION Approved long-acting treatments in adults with ADHD were effective in improving symptoms and were generally well tolerated.

Abstract
ADHD, sleep, and ADHD treatments are highly interrelated. In this review, we describe the effects of stimulants and non stimulant medications on sleep in children, adolescents, and adults with ADHD. Clinical predictors of sleep problems during pharmacotherapy include age, sleep problems prior to initiating treatment, and dose and dosing schedule. As yet, we have little understanding of the biological or genetic factors related to individual variation in drug response and sleep.
