RESUMEN
BACKGROUND: Peanut (Arachis hypogaea) allergen powder-dnfp (PTAH) is the first oral immunotherapy indicated for children aged 4 to 17 years with peanut allergy. There are limited real-world data on patients treated with PTAH. OBJECTIVE: To characterize pediatric patients treated with PTAH and associated treatment patterns in US clinical practice. METHODS: US-based physicians with allergy and immunology training treating patients with peanut allergy aged 4 to 17 years with PTAH were recruited from an existing physician panel and completed an online case report form (October to December 2021) with data abstracted from patient medical charts. Physician practice circumstances, patient characteristics, and PTAH treatment patterns were reported. Time to reach the 300-mg dose and treatment persistence were assessed using Kaplan-Meier analysis. RESULTS: A geographically balanced sample of 43 physicians contributed data for 118 demographically diverse pediatric patients. Patients had heterogeneous diagnostic test results, with a wide range of peanut-specific immunoglobulin E levels; 6.8% received an oral food challenge. During the updosing phase, there were no temporary interruptions and 5.1% of the patients required downdosing. Patients reached the 300-mg dose at a median of 21.3 weeks post-initiation. The rate of PTAH persistence at 24 weeks was 93.4%. Only 1 patient discontinued treatment because of treatment-related systemic allergic symptoms, and the remaining discontinuations were for reasons other than treatment-related symptoms. Prophylactic antihistamines were used by 33.9% of the patients to prevent PTAH adverse effects. CONCLUSION: PTAH was prescribed in demographically diverse patients with a wide range of peanut-specific immunoglobulin E levels. Treatment persistence with PTAH was high in this study population, with a small number of patients experiencing treatment modification.

BACKGROUND: Invasive extraintestinal pathogenic Escherichia coli disease (IED) can lead to severe outcomes, particularly among older adults. However, the clinical burden of IED in the U.S. has not been well characterized. METHODS: IED encounters among patients ≥ 60 years old were identified using the PINC AI™ Healthcare Database (10/01/2015-03/31/2020) by either a positive E. coli culture in blood or another normally sterile body site and ≥ 1 sign of systemic inflammatory response syndrome or signs of sepsis, or a positive E. coli culture in urine with urinary tract infection and signs of sepsis. Medical resource utilization, clinical outcomes, and E. coli isolate characteristics were descriptively reported during the first IED encounter and during the following year (observation period). RESULTS: Overall, 19,773 patients with IED were included (mean age: 76.8 years; 67.4% female; 78.5% with signs of sepsis). Most encounters involved community-onset IED (94.3%) and required hospitalization (96.5%; mean duration: 6.9 days), with 32.4% of patients being admitted to the intensive care unit (mean duration: 3.7 days). Most E. coli isolates were resistant to ≥ 1 antibiotic category (61.7%) and 34.4% were resistant to ≥ 3 antibiotic categories. Following their first IED encounter, 34.8% of patients were transferred to a skilled nursing/intermediate care facility, whereas 6.8% had died. During the observation period, 36.8% of patients were rehospitalized, 2.4% had IED recurrence, and in-hospital death increased to 10.9%. CONCLUSIONS: IED is associated with substantial clinical burden at first encounter with considerable long-term consequences. Findings demonstrate the need for increased IED awareness and highlight potential benefits of prevention.

BACKGROUND: Knowledge of risk factors for attention-deficit/hyperactivity disorder (ADHD) may facilitate early diagnosis; however, studies examining a broad range of potential risk factors for ADHD in adults are limited. This study aimed to identify risk factors associated with newly diagnosed ADHD among adults in the United States (US). METHODS: Eligible adults from the IQVIA PharMetrics® Plus database (10/01/2015-09/30/2021) were classified into the ADHD cohort if they had ≥ 2 ADHD diagnoses (index date: first ADHD diagnosis) and into the non-ADHD cohort if they had no observed ADHD diagnosis (index date: random date) with a 1:3 case-to-control ratio. Risk factors for newly diagnosed ADHD were assessed during the 12-month baseline period; logistic regression with stepwise variable selection was used to assess statistically significant association. The combined impact of selected risk factors was explored using common patient profiles. RESULTS: A total of 337,034 patients were included in the ADHD cohort (mean age 35.2 years; 54.5% female) and 1,011,102 in the non-ADHD cohort (mean age 44.0 years; 52.4% female). During the baseline period, the most frequent mental health comorbidities in the ADHD and non-ADHD cohorts were anxiety disorders (34.4% and 11.1%) and depressive disorders (27.9% and 7.8%). Accordingly, a higher proportion of patients in the ADHD cohort received antianxiety agents (20.6% and 8.3%) and antidepressants (40.9% and 15.8%). Key risk factors associated with a significantly increased probability of ADHD included the number of mental health comorbidities (odds ratio [OR] for 1 comorbidity: 1.41; ≥2 comorbidities: 1.45), along with certain mental health comorbidities (e.g., feeding and eating disorders [OR: 1.88], bipolar disorders [OR: 1.50], depressive disorders [OR: 1.37], trauma- and stressor-related disorders [OR: 1.27], anxiety disorders [OR: 1.24]), use of antidepressants (OR: 1.87) and antianxiety agents (OR: 1.40), and having ≥ 1 psychotherapy visit (OR: 1.70), ≥ 1 specialist visit (OR: 1.30), and ≥ 10 outpatient visits (OR: 1.51) (all p < 0.05). The predicted risk of ADHD for patients with treated anxiety and depressive disorders was 81.9%. CONCLUSIONS: Mental health comorbidities and related treatments are significantly associated with newly diagnosed ADHD in US adults. Screening for patients with risk factors for ADHD may allow early diagnosis and appropriate management.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) medication is frequently associated with adverse events (AEs), but limited real-world data exist regarding their costs from a payer's perspective. Therefore, this study evaluated the healthcare costs associated with common AEs among adult patients treated for ADHD in the US. METHODS: Eligible adults treated for ADHD were identified from a large US claims database (1 October 2015-30 September 2021). A retrospective cohort study design was used to assess excess healthcare costs and costs directly related to AE-specific claims per-patient-per-month (PPPM) associated with 10 selected AEs during ADHD treatment. To account for all costs associated with the AE, treatment episodes with a given AE were compared to similar treatment episodes without this AE. Entropy balancing was used to create cohorts with similar characteristics. Studied AEs were selected based on their prevalence in clinical trials for common ADHD medications and were identified from ICD-10-CM diagnosis codes recorded in claims. RESULTS: Among the 461,464 patients included (mean age: 34.2 years; 45.5% males), 49.4% had ≥1 AE during their treatment episode. Treatment episodes with AEs were associated with statistically significant AE-specific medical costs (erectile dysfunction: $57; fatigue: $82; dry mouth: $90; diarrhea: $162; insomnia: $147; anxiety: $281; nausea: $299; constipation: $356; urinary hesitation: $491; feeling jittery: $723) and excess healthcare costs PPPM (erectile dysfunction: $120, fatigue: $248, insomnia: $265, anxiety: $380, diarrhea: $441, dry mouth: $485, nausea: $709, constipation: $802, urinary hesitation: $1,105, feeling jittery: $1,160; p < .05). LIMITATIONS: AEs were identified based on recorded diagnosis on medical claims and likely represent more severe AEs. Therefore, costs may not be representative of milder AEs. CONCLUSIONS: This study found that AEs occurring during ADHD treatment episodes are associated with significant healthcare costs. This highlights the potential of treatments with favorable safety profiles to alleviate the burden experienced by patients and the healthcare system.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) has been shown to pose considerable clinical and economic burden; however, research quantifying the excess burden attributable to common psychiatric comorbidities of ADHD among pediatric patients is scarce. This study assessed the impact of anxiety and depression on healthcare resource utilization (HRU) and healthcare costs in pediatric patients with ADHD in the United States. METHODS: Patients with ADHD aged 6-17 years were identified in the IQVIA PharMetrics Plus database (10/01/2015-09/30/2021). The index date was the date of initiation of a randomly selected ADHD treatment. Patients with ≥ 1 diagnosis for anxiety and/or depression during both the baseline (6 months pre-index) and study period (12 months post-index) were classified in the ADHD+anxiety/depression cohort; those without diagnoses for anxiety nor depression during both periods were classified in the ADHD-only cohort. Entropy balancing was used to create reweighted cohorts. All-cause HRU and healthcare costs during the study period were compared using regression analyses. Cost analyses were also performed in subgroups by comorbid conditions. RESULTS: The reweighted ADHD-only cohort (N = 204,723) and ADHD+anxiety/depression cohort (N = 66,231) had similar characteristics (mean age: 11.9 years; 72.8% male; 56.2% had combined inattentive and hyperactive ADHD type). The ADHD+anxiety/depression cohort had higher HRU than the ADHD-only cohort (incidence rate ratios for inpatient admissions: 10.3; emergency room visits: 1.6; outpatient visits: 2.3; specialist visits: 5.3; and psychotherapy visits: 6.1; all p < 0.001). The higher HRU translated to greater all-cause healthcare costs; the mean per-patient-per-year (PPPY) costs in the ADHD-only cohort vs. ADHD+anxiety/depression cohort was $3,988 vs. $8,682 (p < 0.001). All-cause healthcare costs were highest when both comorbidities were present; among patients with ADHD who had only anxiety, only depression, and both anxiety and depression, the mean all-cause healthcare costs were $7,309, $9,901, and $13,785 PPPY, respectively (all p < 0.001). CONCLUSIONS: Comorbid anxiety and depression was associated with significantly increased risk of HRU and higher healthcare costs among pediatric patients with ADHD; the presence of both comorbid conditions resulted in 3.5 times higher costs relative to ADHD alone. These findings underscore the need to co-manage ADHD and psychiatric comorbidities to help mitigate the substantial burden borne by patients and the healthcare system.
RESUMEN
BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous condition with extensive psychiatric comorbidities. ADHD has been associated with substantial clinical and economic burden; however, little is known about the incremental burden specifically attributable to psychiatric comorbidities of ADHD in adults. OBJECTIVE: To assess the impact of psychiatric comorbidities, specifically anxiety and depression, on health care resource utilization (HRU) and costs in treated adults with ADHD in the United States. METHODS: A retrospective case-cohort study was conducted. Adults with ADHD were identified in the IQVIA PharMetrics Plus database (10/01/2015-09/30/2021). The index date was defined as the date of initiation of a randomly selected ADHD treatment. The baseline period was defined as the 6 months prior to the index date, and the study period as the 12 months following the index date. Patients with at least 1 diagnosis for anxiety and/or depression during both the baseline and study periods were classified in the ADHD+anxiety/depression cohort, whereas those without diagnoses for anxiety or depression at any time were classified in the ADHD-only cohort. Entropy balancing was used to create reweighted cohorts with similar baseline characteristics. All-cause HRU and health care costs were assessed during the study period and compared between cohorts using regression analyses. Cost analyses were also conducted in subgroups stratified by comorbid conditions. RESULTS: After reweighting, patients in the ADHD-only cohort (N = 276,906) and ADHD+anxiety/depression cohort (N = 217,944) had similar characteristics (mean age 34.1 years; 54.8% male). All-cause HRU was higher in the ADHD+anxiety/depression cohort than the ADHD-only cohort (incidence rate ratios for inpatient admissions: 4.5, emergency department visits: 1.8, outpatient visits: 2.0, and psychotherapy visits: 6.4; all P < 0.01). All-cause health care costs were more than 2 times higher in the ADHD+anxiety/depression cohort than the ADHD-only cohort (mean per-patient per-year [PPPY] costs in ADHD-only vs ADHD+anxiety/depression cohort: $5,335 vs $11,315; P < 0.01). Among the ADHD+anxiety/depression cohort, average all-cause health care costs were $9,233, $10,651, and $15,610 PPPY among subgroup of patients with ADHD and only anxiety, only depression, and both anxiety and depression, respectively. CONCLUSIONS: Comorbid anxiety and depression is associated with additional HRU and costs burden in patients with ADHD. Comanagement of these conditions is important and has the potential to alleviate the burden experienced by patients and the health care system.

AIMS: To describe and compare clinical characteristics, healthcare costs, and institutionalization/mortality outcomes among patients with and without agitation associated with Alzheimer's dementia (AAD). METHODS: Data from the Reliant Medical Group database (01/01/2016-03/31/2020) were used, including claims, electronic medical records, and clinical information/physician notes abstracted from medical charts. Patients aged ≥55 years with Alzheimer's dementia (AD) were observed during a randomly selected 12-month study period after AD diagnosis. Using information recorded in medical charts, patients were classified into cohorts based on experiencing (agitation cohort) and not experiencing (no agitation cohort) agitated behaviours during the study period. Entropy balancing was used to create reweighted cohorts with similar characteristics. Study outcomes (patient demographic and clinical characteristics, treatments received, healthcare costs, institutionalization and death events) were compared between cohorts; agitation characteristics were described for the agitation cohort only. RESULTS: Among 711 patients included in the study, 240 were classified in the agitation cohort and 471 in the no agitation cohort. After reweighting, several comorbidities were more frequently observed in the agitation versus no agitation cohort, including infection, depression, and altered mental status. Use of antidepressants, anticonvulsants, antipsychotics, and antianxiety medications was more common in the agitation versus no agitation cohort. Common agitated behaviours included hitting (20.8%), pacing/aimless wandering (17.5%), and cursing/verbal aggression (15.0%). Total all-cause healthcare costs were $4287 per-patient-per-year higher in the agitation cohort versus no agitation cohort (p = 0.04), driven by higher inpatient costs. Death was more common and time to death and institutionalization were shorter in the agitation versus no agitation cohort. LIMITATIONS: Results may not be generalizable to the US population with AD. CONCLUSIONS: Among patients with AD, agitation was associated with shorter time to death/institutionalization and increased comorbidities, medication use, and healthcare costs, highlighting the additional clinical and economic burden that agitation poses to patients and the healthcare system.

OBJECTIVE: To compare real-world treatment persistence, dose escalation, rates of opportunistic or serious infections, and healthcare costs in patients with Crohn's disease (CD) receiving vedolizumab (VDZ) vs ustekinumab (UST) in the United States. METHODS: A retrospective observational study in adults with CD initiated on VDZ or UST on/after 26 September 2016, was performed using the IBM Truven Health MarketScan databases (1 January 2009-30 September 2018). Rates of treatment persistence, dose escalation, opportunistic or serious infection-related encounters, and healthcare costs per patient per month (PPPM) were evaluated. Entropy balancing was used to balance patient characteristics between cohorts. Event rates were assessed using weighted Kaplan-Meier analyses and compared between cohorts using log-rank tests. Healthcare costs were compared between cohorts using weighted 2-part models. RESULTS: 589 VDZ and 599 UST patients were included (172 [29.2%] and 117 [19.5%] were bio-naïve, respectively). After weighting, baseline characteristics were comparable between cohorts. No significant difference in rates of treatment persistence (12-month: VDZ, 76.5%; UST, 82.1%; p = .17), dose escalation (12-month: VDZ, 29.3%; UST, 32.7%; p = .97), or opportunistic or serious infection-related encounters were observed between VDZ and UST. Total mean healthcare costs were significantly lower for patients treated with VDZ vs UST (mean cost difference = -$5051 PPPM; p < .01). Findings were consistent in bio-naïve patients. CONCLUSIONS: In this real-world study, similar treatment persistence, dose escalation, and rates of opportunistic or serious infections were observed with VDZ- and UST-treated patients with CD. However, VDZ was associated with a significantly lower cost outlay for healthcare systems.
Crohn's disease (CD) causes inflammation in the digestive system. Vedolizumab (VDZ) and ustekinumab (UST) are therapies for patients with CD. Little is known about the clinical outcomes and healthcare costs of VDZ versus UST in the real world in the United States. We used health claims data and found that VDZ and UST had comparable real-world clinical outcomes. After 12 months of treatment, the proportions of patients with CD who stayed on treatment and those who needed to increase therapy dose were similar with VDZ and UST. The rate of infection was also similar between the two groups of patients. However, the monthly healthcare costs were $5051 less for patients treated with VDZ than with UST. This was mainly due to the lower cost of VDZ, which was almost half of that of UST. The lower treatment costs with VDZ may provide substantial savings for the healthcare system and patients specifically. Future cost-effectiveness studies on VDZ and UST are needed to aid treatment selection for patients with CD.

INTRODUCTION: Objective assessment of treatment effectiveness using real-world claims data is challenging. This study assessed treatment-free intervals (TFI) as a proxy for treatment effectiveness, and all-cause healthcare costs among adult patients with irritable bowel syndrome with diarrhea (IBS-D) treated with rifaximin or eluxadoline in the USA. METHODS: Adult patients (18-64 years) with IBS-D and ≥ 1 rifaximin or eluxadoline prescription were identified in the IQVIA PharMetrics® Plus database (10/01/2015-12/31/2021) and classified into two mutually exclusive cohorts (i.e., rifaximin and eluxadoline). Index date was the date of rifaximin or eluxadoline initiation. Entropy-balanced baseline characteristics, TFI (periods of ≥ 30 consecutive days without IBS-D treatment), and healthcare costs were reported. Healthcare costs were compared between cohorts using mean cost differences. RESULTS: There were 7094 and 2161 patients in the rifaximin and eluxadoline cohorts, respectively. After balancing, baseline characteristics (mean age 44.1 years; female 72.4%) were similar between cohorts. A higher proportion of patients treated with rifaximin achieved a TFI of ≥ 30 days (76.2% vs. 66.7%), ≥ 60 days (67.0% vs. 47.0%), ≥ 90 days (61.0% vs. 38.7%), ≥ 180 days (51.7% vs. 31.0%), and ≥ 240 days (47.7% vs. 27.9%) compared to eluxadoline. Among patients with a TFI ≥ 30 days, mean TFI durations were 8.3 and 6.0 months for the rifaximin and eluxadoline cohorts. Mean all-cause healthcare costs were lower for rifaximin vs. eluxadoline ($18,316 vs. $23,437; p = 0.008), primarily driven by pharmacy costs ($7348 vs. $10,250; p < 0.001). In a simulated health plan of one million commercially insured lives, initiating 50% of patients on rifaximin instead of eluxadoline resulted in total cost savings of $2.1 million per year or $0.18 per-member-per-month. CONCLUSIONS: This real-world study suggests that TFI is a meaningful surrogate measure of treatment effectiveness in IBS-D. Patients treated with rifaximin had longer treatment-free periods and lower healthcare costs than patients treated with eluxadoline.

OBJECTIVE: Describe symptoms associated with ADHD/treatment-related adverse side effects among adults with ADHD in the US and assess their impact on quality of life (QoL) and work productivity. METHODS: An online survey among adults receiving ADHD medications in the US was conducted to collect information relating to symptoms associated with ADHD/treatment-related adverse side effects. Participants were recruited from the panel of a well-established market research firm, Dynata, from 26 July to 30 July 2021 and were included in the study if they met the eligibility criteria and were willing to participate in the survey. Correlations between symptoms and key outcomes (QoL/employment/work impairment) were estimated using linear regression analyses. RESULTS: Of 585 participants, 95.2% experienced ≥1 symptom associated with ADHD/treatment-related adverse side effects in the past month (average = 5.8 symptoms). The number of symptoms was significantly correlated with reduced QoL, reduced probability of being employed, and increased work/activity impairment. Among subgroups with insomnia/other sleep disturbances and emotional impulsivity/mood lability, 50.4% and 44.7% reported their symptoms had "a lot" or "extremely" negative impact on their overall well-being, respectively. CONCLUSIONS: Symptoms associated with ADHD/treatment-related adverse side effects are common and have a substantial negative impact on QoL and reduces patients' probability of employment. Improved management of ADHD/treatment-related adverse side effects and more tolerable treatment options have the potential to improve QoL and work productivity among adults with ADHD.

BACKGROUND: Although invasive Escherichia coli disease (IED) can lead to severe clinical outcomes, little is known about the associated medical resource use and cost burden of IED in US hospitals. OBJECTIVE: To comprehensively describe medical resource use and costs associated with IED during the initial IED event and over the subsequent 12 months. METHODS: Patients aged 60 years or older with 1 or more IED encounters were identified from the PINC AI Healthcare US hospital database (October 1, 2015, to March 31, 2020). The index encounter was defined as the first encounter with a positive E coli culture in a normally sterile site (group 1 IED) or positive E coli culture in urine with signs of sepsis (group 2 IED). Encounters with a positive culture from other bacteria or fungal pathogens were excluded. Outcomes were descriptively reported between admission and discharge for the index encounter and more than 1 - year post-index discharge. Medical resource use and costs included inpatient admissions and outpatient hospital services; costs were reported from a hospital's perspective (ie, charged amount) in 2021 USD. RESULTS: A total of 19,773 patients were identified (group 1 IED = 51.8%; group 2 IED = 48.2%). Mean age was 76.8 years, 67.4% were female, and 82.1% were White. Most index encounters were community-onset (94.3%) and led to hospitalization (96.5%) (mean inpatient days = 6.9 days). During the 1 - year post-index, 36.8% of patients had 1 or more all-cause hospitalizations. Mean [median] total all-cause hospital costs (as captured through the PINC AI Healthcare database) amounted to $16,760 [$11,340] during the index encounter and $10,942 [$804] during the 1 - year post-index; these costs were higher in the presence of sepsis and multidrug resistance and among hospital-onset IED. CONCLUSIONS: IED is associated with a substantial medical resource use and economic burden both during the initial encounter and over the following year in older adults. This highlights the critical need and potential benefits of preventive measures that may reduce the incidence of IED and associated economic burden.

AIM: To assess the impact of rifaximin (± lactulose) use following discharge of an initial overt hepatic encephalopathy (OHE) hospitalization on OHE rehospitalizations and healthcare costs in a real-world setting. METHODS: Adults (18-64 years) with an OHE hospitalization were identified from MarketScan® Commercial claims (Q4'15-Q2'20), classified into two mutually exclusive treatment cohorts (i.e. rifaximin and no rifaximin treatment), and further stratified into four subgroups based on decreasing quality of care (QoC; i.e. Type 1 - rifaximin without delay post-discharge; Type 2 - rifaximin with delay post-discharge; Type 3 - lactulose only post-discharge; Type 4 - no rifaximin/lactulose treatment post-discharge). The impact of rifaximin use on 30-day and annualized OHE hospitalizations and healthcare costs were assessed between cohorts and by the QoC subgroup. RESULTS: Characteristics were similar between the rifaximin (N = 1,452; Type 1: 1,138, Type 2: 314) and no rifaximin (N = 560; Type 3:337, Type 4: 223) treatment cohorts. The 30-day risk of OHE rehospitalization was lower for the rifaximin vs. no rifaximin treatment cohort (odds ratio 0.56, p < .01) and increased with decreasing QoC. The annual rate of OHE hospitalizations was 59% lower for the rifaximin treatment cohort (incidence rate ratio 0.41, p < .01) and increased with decreasing QoC. Compared to the no rifaximin treatment cohort, the rifaximin treatment cohort had higher pharmacy costs, lower medical costs, and no difference in total healthcare costs. LIMITATIONS: This was a claims-based study subject to common data limitations such as billing inaccuracies or omissions in coded claims. Total healthcare costs were reported from a payer's perspective, which do not capture indirect costs associated with patient burden. CONCLUSIONS: Initiation of rifaximin after an OHE hospitalization was associated with reduced OHE hospitalizations both in the 30-days following and annually. Further, reduced medical costs offset increased pharmacy costs, and no annual cost differences were observed between cohorts.

INTRODUCTION: This study aimed to examine the reasons underlying treatment changes among pediatric patients with attention-deficit/hyperactivity disorder (ADHD). METHODS: Data were obtained through online medical chart abstraction (08/2021-09/2021). Eligible patients with ADHD had initiated a treatment regimen at ages 6-17 and within 1-5 years of chart abstraction. Reasons contributing to treatment changes were analyzed for a randomly selected treatment episode. ADHD/treatment-related complication rate was also described. Results were reported overall and among children (ages 6-12) and adolescents (ages 13-17), separately. Physicians' perspective on adherence among their child, adolescent, and adult patients was assessed through an online survey. RESULTS: A total of 156 physicians abstracted 434 patient charts (235 children + 199 adolescents). Mean patient age was 11.3 years, and 68.7% were male. Inadequate/suboptimal symptom management was the most common reason for treatment discontinuation (50/83 [60.2%]), add-on (17/21 [81.0%]), and dose increase (189/237 [79.7%]). Patient/parent/family attitude/dislike of medication and ADHD/treatment-related complications were common reasons for treatment discontinuation, add-on, switch, and dose decrease. Overall, 42.4% of patients had ≥ 1 documented ADHD/treatment-related complication, insomnia/sleep disturbances being the most common (9.7%). Among patients with ≥ 1 complication, 75.5% reported the experience/fear of complications had a negative impact on their treatment adherence. Results were similar among children and adolescents. Physicians reported taking actions toward patients' non-adherence by further educating patients, closer monitoring, and changing the prescribed ADHD medication. CONCLUSION: Lack of effectiveness and ADHD/treatment-related complications are important reasons for treatment changes among children and adolescents with ADHD, highlighting the need for more effective and tolerable treatments to mitigate the burden of ADHD.

Rationale & Objective: Chronic kidney disease (CKD) has a far-reaching impact on both patients and care partners, which can be further compounded by frequent complications such as anemia. This study assessed the burden experienced by patients with CKD and the care partners of patients with CKD, with and without anemia. Study Design: Online survey. Setting & Participants: Adult patients with CKD and the care partners of adult patients with CKD living in the United States were recruited through the American Association of Kidney Patients and a third-party online panel (January 9, 2020-March 12, 2020). Outcomes: Patient and care partner characteristics, care received or provided; health-related quality of life, and work productivity. Analytical Approach: Descriptive statistics were reported separately based on the presence or absence of anemia. Results: In total, 410 patients (anemia: n=190, no anemia: n=220) and 258 care partners (anemia: n=110, no anemia: n=148) completed the survey. Most patients reported receiving paid or unpaid care because of their health condition (anemia: 58.9%, no anemia: 50.9%), with an overall average of 14.2 and 11.3 h/wk among the anemia and no anemia patients, respectively. The care partners also reported providing numerous hours of care (anemia: 33.6 h/wk, no anemia: 38.0 h/wk), especially care partners living with their care recipient (anemia: 52.6 h/wk, no anemia: 42.8 h/wk). Among the patients, those with anemia reported a numerically lower average health-related quality of life (Functional Assessment of Cancer Therapy-Anemia score, anemia: 110.1; no anemia: 121.6). Most care partners reported a severe or very severe burden (Burden Scale for Family Caregivers-Short Version score≥15, anemia: 69.1%; no anemia: 58.8%). The work productivity impairment was substantial among employed patients (anemia: 44.9%, no anemia: 35.4%) and employed care partners (anemia: 47.9%, no anemia: 40.7%). Limitations: The survey results may have been subject to selection and recall biases; moreover, the observational nature of the study does not allow for causal inferences. Conclusions: Patients with CKD and the care partners of patients with CKD experience a considerable burden, especially when anemia is present.
RESUMEN
AIMS: To assess healthcare resource utilization (HRU) and healthcare costs among women with hormone receptor-positive and human epidermal growth factor receptor 2-negative advanced breast cancer (HR+/HER2- aBC) treated with cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors. METHODS: Women with HR+/HER2- aBC, initiating CDK4/6 inhibitor treatment were identified using IBM MarketScan Commercial and Medicare Supplemental databases (Q1/2000-Q3/2018). Based on the first CDK4/6 inhibitor patients received (index therapy), three cohorts were identified: abemaciclib, palbociclib, and ribociclib. The baseline period (six months preceding treatment initiation) was used to describe patient characteristics. All-cause HRU and direct total healthcare costs (medical and pharmacy) from treatment initiation until the earliest of the end of index therapy, continuous health plan enrollment, or data availability, were compared for the ribociclib cohort versus the abemaciclib and palbociclib cohorts, separately, using weighted regression analyses balanced on baseline covariates. RESULTS: Average age at treatment initiation was â¼60 years and the majority of patients were postmenopausal (abemaciclib: 92%; palbociclib: 92%; ribociclib: 79%). Average follow-up duration was 3.9, 8.8, and 5.9 months for the abemaciclib, palbociclib, and ribociclib cohorts, respectively. After reweighting, HRU was not statistically different between the ribociclib and abemaciclib cohorts, however, the ribociclib cohort incurred significantly lower total healthcare costs (-$5,452; 95% CI: -$8,726; -$1,139, p = .01). Medical costs (driven by outpatient costs) and pharmacy costs (driven by CDK4/6 inhibitor costs) were significantly lower for the ribociclib cohort. Among the reweighted ribociclib and palbociclib cohorts, HRU and total healthcare costs were not statistically different, although the ribociclib cohort had lower outpatient costs per-patient-per-month (-$1,245, 95% CI: -$2,349; -$37, p = .04). LIMITATIONS: Due to the retrospective, observational design, treatment cohorts were not randomly assigned. CONCLUSIONS: During CDK4/6 inhibitor therapy, ribociclib patients tended to incur lower medical and pharmacy costs than abemaciclib patients. Among ribociclib and palbociclib patients, HRU and healthcare costs were similar.

OBJECTIVE: To assess treatment patterns in adults with attention-deficit/hyperactivity disorder (ADHD) and associated healthcare costs in a real-world US setting. METHODS: Claims data from the IBM MarketScan Commercial Subset (Q1/2014-Q4/2018) was used to identify adults diagnosed with ADHD who newly initiated on ADHD treatment (index date). Treatment sequences were defined using an algorithm; for each sequence, the regimen comprised all ADHD-related agents observed within 30 d of the first agent during the 12-month study period. Treatment changes included discontinuation, switch, add-on, and drop. Treatment characteristics were described for the first treatment regimen observed. Total adjusted annual healthcare costs were compared between patients with no treatment change and patients with 1, 2, and ≥3 treatment changes. RESULTS: Among 122,881 adults with ADHD, the majority initiated a stimulant (95.1%) as their first treatment regimen observed; 9.3% of patients initiated combination therapy of ≥2 ADHD-related agents, and 34.9% of patients had psychotherapy. After an average first treatment regimen duration of 7.1 months, 50.2% of patients experienced a treatment change (22.5% discontinued, 17.5% switched, 5.3% had an add-on, and 4.6% had a treatment drop). Among those who discontinued, 44.8% did so within the first month of initiation. Mean annual healthcare costs were higher among patients with at least 1 treatment change compared to those with no treatment changes; excess costs increased with each additional treatment change. CONCLUSIONS: Treatment changes were commonly observed and were associated with excess healthcare cost, emphasizing the unmet treatment needs of adults with ADHD in the US.

BACKGROUND: Erythropoiesis-stimulating agents (ESAs) are commonly used to treat anemia due to chronic kidney disease (CKD). In addition to drug acquisition costs, the administration of ESAs can include direct and indirect costs due to the needle-based route of administration (eg, time spent by health care staff administering therapy, and patients' and caregivers' time spent receiving or assisting with therapy). However, a comprehensive assessment of the costs associated with the administration of ESAs is lacking. OBJECTIVE: To estimate the excess costs associated with the needle-based administration of ESAs for the treatment of anemia due to non-dialysis-dependent (NDD) CKD in the United States in 2019 from a societal perspective. METHODS: Excess costs associated with ESA administration were estimated as the sum of annual costs that could be avoided with the introduction of an oral treatment with comparable safety and efficacy to ESAs. Cost components included direct health care costs, transportation costs, and work productivity loss costs from the perspective of both patients and caregivers (as applicable). Costs were estimated based on scientific publications, governmental agencies, and the results of a recent survey of US patients and caregivers of patients with anemia and CKD. The setting of the administration (ie, at home vs in clinic), frequency of administration, and insurance type were considered. RESULTS: At the societal level, annual excess costs associated with ESA administration were estimated at $2.5 billion in the United States in 2019, based on an estimated 462,005 patients with anemia and NDD-CKD treated with ESAs. Overall, 94.4% ($2.4 billion) of these costs were incurred from in-clinic ESA administration. When stratifying costs by insurance type, Medicare-insured patients accounted for 79.4% ($2.0 billion) of total annual excess costs. The largest contributor to total annual excess costs was direct health care costs ($1.4 billion, 54.9%), followed by patient work productivity loss costs ($846 million, 33.9%), caregiver work productivity loss costs ($197 million, 7.9%), and transportation costs ($81 million, 3.3%). Total annual excess costs of in-clinic administration ranged from $2,572 per patient receiving monthly administration to $20,948 per patient receiving thrice-weekly administration, while the total annual excess costs of at-home administration ranged from $1,123 per patient receiving monthly administration to $2,109 per patient receiving thrice-weekly administration. At the ESA administration level (ie, for each ESA administration), total excess costs were estimated at $128 per in-clinic ESA administration and $7 per at-home ESA administration, excluding monitoring costs. CONCLUSIONS: The needle-based administration of ESAs in patients with NDD-CKD is associated with a substantial economic burden. The introduction of an oral treatment has the potential to result in important cost savings from a societal perspective.

The head direction (HD) signal is thought to originate in the reciprocal connections between the dorsal tegmental nuclei (DTN) and the lateral mammillary nuclei (LMN) and lesions to these structures disrupt the HD signal in downstream structures. Lesions to the DTN also disrupt performance on spatial tasks where directional heading is thought to be important. In Experiment 1, rats with bilateral electrolytic lesions of the LMN and sham controls were trained on 2 tasks previously shown to be sensitive to DTN damage. Rats were first trained on either a direction or rotation problem in a water T maze. LMN-lesioned rats were impaired relative to sham controls, on both the first block of 8 trials and on the total number of trials taken to reach criterion. In the food-foraging task, rats were trained to leave a home cage at the periphery of a circular table, find food in a food cup at the center of the table, and return to the home cage. Again, LMN-lesioned rats were impaired relative to sham rats, making more errors on the return component of the foraging trip. In Experiment 2, rats with electrolytic LMN lesions were also impaired on a dry land version of the direction and rotation problems and had difficulty discriminating between reinforced and nonreinforced locations on a 12-arm maze. These results build on previous behavioral and cell-recording studies and demonstrate the importance of the direction system to spatial learning.
