Shared Decision-Making in the Treatment of Multiple Sclerosis: Results of a Cross-Sectional, Real-World Survey in Europe and the United States

Introduction

Multiple sclerosis (MS) is a neurodegenerative disease characterized by progressive deterioration of cognitive and physical functioning, reducing activities of daily living and quality of life (QoL). Several treatments are available that modify the course of the disease and reduce the frequency of relapses. Although effective, all treatment options are accompanied by adverse events, and this study aimed to assess the extent to which patients were involved in the choice of treatment.

Methods

Data were drawn from the Adelphi Multiple Sclerosis Disease Specific Program (DSP)™, a cross-sectional survey of healthcare practitioners (HCP) and their patients with MS in real-world clinical settings in Europe and the United States (US) between December 2020 and July 2021. HCPs reported patient demographics, clinical characteristics, current and previous treatment, and treatment outcomes. Patients voluntarily completed questionnaires reporting the physical and psychological impact of their MS and its treatment. Regression analysis with inverse probability of treatment weighting was used to compare treatment outcomes in patients actively involved in their current treatment choice with those who were not.

Results

Of a total of 692 patients, median age 40 years and 64% female, mostly diagnosed with relapsing-remitting MS, those who were involved in shared decision-making tended to choose oral therapies such as dimethyl fumarate more often than HCPs. MS had greater impact on physical and psychological functioning in patients whose HCP made treatment decisions solely. Patients involved in decision-making reported greater satisfaction with their treatment and a better QoL.

Discussion

Because no single optimal therapy exists for patients with MS, treatments should be individualized with consideration of patients' preferences. Our study shows that shared decision-making is under-utilized in the management of MS and supports the benefits of patient involvement.

Conclusion

Patients who have an active role in treatment decision-making show improved wellbeing and QoL, and overall treatment satisfaction.

Biological Age Mediates the Effects of Perceived Neighborhood Problems on Heart Failure Risk Among Black Persons

OBJECTIVE

We assessed whether biological age, measured by the epigenetic clock GrimAge, mediates the association of objective and subjective neighborhood disadvantage with incident HF among Black persons.

METHODS

Participants were 1448 self-reported Black adults (mean age (standard deviation, SD) = 64.3 (5.5)) dually enrolled in two community-based cohorts in Jackson, Mississippi, the ARIC and JHS cohorts, who were free of HF as of January 1, 2000. Incident HF events leading to hospitalization through December 31, 2017, were classified using ICD-9 discharge codes of HF. Multilevel age- and sex-adjusted Cox causal mediation models were used to examine whether biological age (at the person and neighborhood level) mediated the effects of objective (the National Area Deprivation Index, ADI) and subjective (perceived neighborhood problems) neighborhood disadvantage on incident HF.

RESULTS

A total of 334 incident hospitalized HF events occurred over a median follow-up of 18.0 years. The total effect of the ADI and perceived neighborhood problems (SD units) on HF was hazard ration (HR) = 1.26 and 95% confidence interval (CI) 0.98-1.56 and HR = 1.26 and 95% CI 1.10-1.41, respectively. GrimAge mediated a majority of the effect of perceived neighborhood problems on HF (person-level indirect effect HR = 1.07; 95% CI 1.02-1.12 and neighborhood-level indirect effect HR = 1.18; 95% CI 1.03-1.34), with the combined indirect effect explaining 94.8% of the relationship. The combined indirect effect of ADI on incident HF was comparable but not statistically significant.

CONCLUSIONS

Subjective neighborhood disadvantage may confer an increased risk of HF among Black populations.

Cross-walk of the Chronic Liver Disease Questionnaire for Nonalcoholic Steatohepatitis (CLDQ-NASH) and the EuroQol EQ-5D-5L in patients with NASH

BACKGROUND

Nonalcoholic steatohepatitis (NASH) is a chronic progression of nonalcoholic fatty liver disease, which can negatively impact the health-related quality of life (HRQoL) of affected individuals. HRQoL in NASH has been assessed using the disease-specific Chronic Liver Disease Questionnaire for NASH (CLDQ-NASH) and the generic EuroQol EQ-5D-5L. As the performance of these instruments relative to each other is unknown, we performed a cross-walk analysis of CLDQ-NASH to EQ-5D-5L using data from a real-world NASH population.

METHODS

Data were drawn from the Adelphi Real World 2019 NASH Disease Specific Programme, a cross-sectional survey of physicians and their patients in the United States. Patients with physician-diagnosed NASH completed a questionnaire that included the CLDQ-NASH and EQ-5D-5L. Mapping from CLDQ-NASH to EQ-5D-5L was done using tenfold cross-validation; performance was assessed using root-mean squared error as accuracy measure. Subgroup analyses compared performance of the models in obese versus non-obese patients and patients with versus without type 2 diabetes (T2D).

RESULTS

Data from 347 patients were included in this analysis. Overall, 2172 models were tested for predicting EQ-5D-5L index score from CLDQ-NASH score. The best model for this mapping was a generalized linear model using Gaussian distribution and a power link. The best model for mapping from CLDQ-NASH domains to the EQ-5D-5L was a fractional logistic model. Models performed better at predicting upper versus lower values of EQ-5D-5L, for non-obese versus obese patients, and for patients without versus with T2D.

CONCLUSION

We describe a scoring algorithm for cross-walking the CLDQ-NASH to the EQ-5D-5L enabling health status comparisons of HRQoL across studies.

Impact of advanced Parkinson's disease on caregivers: an international real-world study

BACKGROUND

Caring for a partner or family member with Parkinson's disease (PD) negatively affects the caregiver's own physical and emotional well-being, especially those caring for people with advanced PD (APD). This study was designed to examine the impact of APD on caregiver perceived burden, quality of life (QoL), and health status.

METHODS

Dyads of people with PD and their primary caregivers were identified from the Adelphi Parkinson's Disease Specific Program (DSP™) using real-world data from the United States, Japan and five European countries. Questionnaires were used to capture measures of clinical burden (people with PD) and caregiver burden (caregivers).

RESULTS

Data from 721 patient-caregiver dyads in seven countries were captured. Caregivers had a mean age 62.6 years, 71.6% were female, and 70.4% were a spouse. Caregivers for people with APD had a greater perceived burden, were more likely to take medication and had lower caregiver treatment satisfaction than those caring for people with early or intermediate PD; similar findings were observed for caregivers of people with intermediate versus early PD. Caregivers for people with intermediate PD were also less likely to be employed than those with early PD (25.3% vs 42.4%) and spent more time caring (6.6 vs 3.2 h/day).

CONCLUSIONS

This real-world study demonstrates that caregivers of people with APD experience a greater burden than those caring for people with early PD. This highlights the importance of including caregiver-centric measures in future studies, and emphasizes the need for implementing treatments that reduce caregiver burden in APD.

Cardiovascular concentration-effect relationships of amodiaquine and its metabolite desethylamodiaquine: Clinical and preclinical studies

AIMS

Amodiaquine is a 4-aminoquinoline used extensively for the treatment and prevention of malaria. Orally administered amodiaquine is largely converted to the active metabolite desethylamodiaquine. Amodiaquine can cause bradycardia, hypotension, and electrocardiograph QT interval prolongation, but the relationship of these changes to drug concentrations is not well characterized.

METHODS

We conducted a secondary analysis of a pharmacokinetic study of the cardiac safety of amodiaquine (10 mg base/kg/day over 3 days) in 54 Kenyan adults (≥18 years) with uncomplicated malaria. Nonlinear mixed effects modelling was used to assess amodiaquine and desethylamodiaquine concentration-effect relationships for vital sign (pulse rate, blood pressure) and electrocardiograph interval (QT, QRS, PR) outcomes. We also measured the spontaneous beating heart rate after cumulative dosing of amodiaquine and desethylamodiaquine in isolated mouse atrial preparations.

RESULTS

Amodiaquine and desethylamodiaquine caused concentration-dependent mean decreases in pulse rate (1.9 beats/min per 100 nmol/L; 95% confidence interval: 1.5-2.4), supine systolic blood pressure (1.7 mmHg per 100 nmol/L; 1.2-2.1), erect systolic blood pressure (1.5 mmHg per 100 nmol/L; 1.0-2.0) and erect diastolic blood pressure (1.4 mmHg per 100 nmol/L; 1.0-1.7). The mean QT interval prolongation was 1.4 ms per 100 nmol/L irrespective of correction factor after adjustment for residual heart rate dependency. There was no significant effect of drug concentration on postural change in blood pressure or PR and QRS intervals. In mouse atria, the spontaneous beating rate was significantly reduced by amodiaquine (n = 6) and desethylamodiaquine (n = 8) at 3 μmol/L (amodiaquine: 10 ± 2%; desethylamodiaquine: 12 ± 3%) and 10 μmol/L (amodiaquine: 50 ± 7%; desethylamodiaquine: 46 ± 6%) concentrations with no significant difference in potency between the 2 compounds.

CONCLUSION

Amodiaquine and desethylamodiaquine have concentration-dependent effects on heart rate, blood pressure, and ventricular repolarization.

Medication beliefs, adherence, and outcomes in people with asthma: The importance of treatment beliefs in understanding inhaled corticosteroid nonadherence-a retrospective analysis of a real-world data set

Background

Poor adherence to inhaled corticosteroids (ICSs) increases asthma morbidity and mortality and is influenced by patients' treatment beliefs. This study maps patients' beliefs about ICSs across 6 countries examining variations in beliefs, and their relationship with adherence and outcomes.

Objective

We sought to explore the relationship between patient treatment beliefs, and adherence and outcomes in asthma across 6 countries.

Methods

Patients 18 years or older with asthma, receiving ICS alone or in combination with a long-acting β2-agonist, were included from a point-in-time paper survey of patients with asthma in Europe and the United States. Clinical characteristics, such as adherence and asthma control, were collected by self- and physician-report. Patients completed the Beliefs about Medicines Questionnaire, adapted for ICSs. Relationships between patient treatment beliefs, adherence, and outcomes were examined using regression analyses.

Results

Data from 1312 patients were analyzed. Patients were from Germany (24%), the United States (21%), France (21%), Spain (16%), Italy (10%), and the United Kingdom (9%). Most had physician-reported mild-intermittent asthma (87%), and mean age was 40 ± 15.5 years. There was considerable variation in necessity beliefs between countries, with respondents in Italy having more doubts about treatment necessity and respondents in Spain showing higher concerns. Patients with doubts about ICS necessity and high concerns had lower self-reported (necessity: χ2(2) = 34.31, P < .001; concerns: χ2(2) = 20.98, P < .001) and physician-reported adherence (necessity: χ2(2) = 11.70, P = .003; concerns: χ2(2) = 34.45, P < .001). Patients with high necessity beliefs (F(2, 483) = 3.33; P = .037) and high concerns (F(2,483) = 23.46; P < .001) reported poorer control. Physician estimates of adherence did not correlate well with patient self-report (ρ = 0.178, P < .001).

Conclusions

ICS necessity beliefs and concerns were associated with adherence and asthma control. This has implications for the design of adherence interventions.

Community-Based Recruitment Strategies for Young Adult Pacific Islanders into a Randomized Community Smoking Cessation Trial

BACKGROUND

Lung cancer represents the leading cause of cancer death for Pacific Islanders in the United States, but they remain underrepresented in studies leading to the lack of evidence-based cessation programs tailored to their culture and lifestyle.

OBJECTIVES

This paper aims to describe the development of culturally tailored and community informed recruitment materials, and provide lessons learned regarding implementation and adaptation of strategies to recruit Pacific Islander young adult smokers into a randomized cessation study.

METHODS

Development of recruitment materials involved a series of focus groups to determine the cessation program logo and recruitment video. The initial recruitment strategy relied on community-based participatory research partnerships with Pacific Islander community-based organizations, leaders and health coaches with strong ties to the community.Results/Lessons Learned: While the recruitment materials were well received, initial strategies tapered off after the first 3 months of recruitment resulting in the need to revise outreach plans. Revised plans included the creation of a list with more than 200 community locations frequented by Pacific Islander young adult smokers, along with the hiring of part-time recruitment assistants who reflected the age and ethnicities of the desired cessation study participants. These materials and strategies ultimately yielded 316 participants, 66% of whom were recruited by the revised strategies.

CONCLUSIONS

Community-based participatory research approaches not only inform the design of culturally tailored intervention recruitment material and strategies, but also result in innovative solutions to recruitment challenges to address the National Cancer Institute's gaps in science regarding small populations.

Impact of itch and skin pain on quality of life in adult patients with atopic dermatitis in Japan: results from a real-world, point-in-time, survey of physicians and patients

OBJECTIVE

Itch is a common symptom of atopic dermatitis (AD), however, there is limited evidence of the frequency and association of skin pain alongside itch. This study assessed the incremental dual burden and impact of itch and skin pain on satisfaction, quality of life and work productivity in patients with AD in Japan.

METHODS

Data were drawn from the 2020 Adelphi AD Disease Specific Programme, a point-in-time survey of dermatologists (n = 56) and their patients with history of moderate/severe AD (n = 265). Patients were grouped accordingly: no itch/skin pain (No I/SP, reference group, n = 89), itch/no skin pain (I-only, n = 71), and itch and skin pain (I + SP, n = 26). Descriptive analyses were performed alongside a range of regression models, dependent on outcome variables.

RESULTS

I + SP patients had a 4.97-point worse POEM score (p = .005) and 14.5% more overall work impairment (p = .034) versus the reference group. I-only and I + SP patients were 8.92 and 23.5 times more likely, respectively, to experience sleep disruption on a day-to-day basis (both p < .001). I + SP patients were 4.6 times more likely to be bothered by their symptoms (p = .034), had a mean EASI score 6.7 points higher (p = .008) and had 1.39 more areas affected (p = .001). I + SP patients were 7.26 times more likely to express dissatisfaction with lack of improvement in their condition and 8 times more likely to be dissatisfied with convenience of treatment (both p < .05).

CONCLUSION

This dissatisfaction, alongside variations in reported symptomatic burdens, suggests that physicians could consider alternative and/or novel therapeutic approaches for the management of both itch and skin pain.

The Impact of Agitation in Dementia on Caregivers: A Real-World Survey

Background: Dementia patients frequently depend on caregivers. Agitation is a common behavioral dementia symptom particularly burdensome to patients and caregivers. Objective: To assess the association of agitation severity with non-professional caregiver hours, burden, health status, and productivity. Secondarily, to assess the association of agitation severity with these outcomes for patients receiving remote (not living with the patient) and proximate (living with the patient) caregiving. Methods: A retrospective analysis of physician and non-professional caregiver-reported data from a US point-in-time survey. Patients were aged ≥50 years, with early cognitive impairment or dementia. Regression analyses compared outcomes by agitation severity; covariates included age, sex, and clinical characteristics. Results: Data were included for 1,349 patients (non-agitated n = 656, agitated n = 693; no care n = 305, remote care n = 248, proximate care n = 691; unknown care n = 105). Greater agitation was significantly associated (p <  0.05) in all caregivers with increasing: Zarit Burden Interview (ZBI) Total Caregiver Burden, Personal Strain, Role Strain, and Guilt; Work Productivity and Activity Index (WPAI) presenteeism, overall work impairment, and total activity impairment. Higher ZBI Total Caregiver Burden, Personal Strain, and Role Strain were associated with greater agitation in proximate caregivers and higher ZBI Guilt associated with greater agitation in remote caregivers (p <  0.05). Higher WPAI presenteeism and total activity impairment were associated (p <  0.05) with greater agitation in proximate caregivers. Caregiving hours increased with increasing agitation for proximate caregiving (p = 0.001). Conclusion: Greater agitation severity was associated with higher caregiver burden and lower productivity, with higher indirect costs a likely outcome of agitation.

Psychometric Properties of Clinical Indicators for Identification and Management of Advanced Parkinson's Disease: Real-World Evidence From G7 Countries

Introduction

Standardized and validated criteria to define advanced Parkinson’s disease (PD) or identify patient eligibility for device-aided therapy are needed. This study assessed the psychometric properties of clinical indicators of advanced PD and eligibility for device-aided therapy in a large population.

Methods

This retrospective analysis of the Adelphi Parkinson’s Disease Specific Programme collected data from device-aided therapy-naïve people with PD in G7 countries. We assessed the presence of 15 clinical indicators of advancing PD and seven indicators of eligibility for device-aided therapy in patients classified with advanced PD or as eligible for device-aided therapy by the treating physician. Accuracy was assessed using area under the curve (AUC) and multivariable logistic regression models. Construct validity was examined via known-group comparisons of disease severity and burden among patients with and without each clinical indicator.

Results

Of 4714 PD patients, 14.9% were classified with advanced PD and 17.5% as eligible for device-aided therapy by physician judgment. The presence of each clinical indicator was 1.9- to 7.3-fold more likely in patients classified with advanced PD. Similarly, the presence of device-aided therapy eligibility indicators was 1.8- to 5.5-fold more likely in patients considered eligible for device-aided therapy. All indicators demonstrated high clinical screening accuracy for identifying advanced PD (AUC range 0.84–0.89) and patients eligible for device-aided therapy (AUC range 0.73–0.80). The Unified Parkinson’s Disease Rating Scale (UPDRS) score, cognitive function, quality of life, and caregiver burden were significantly worse in indicator-positive patients.

Conclusion

Specific clinical indicators of advanced PD and eligibility for device-aided therapy demonstrated excellent psychometric properties in a large sample, and thus may provide an objective and reliable approach for patient identification and treatment optimization.

Advanced Parkinson’s disease (PD) refers to the stage of disease when motor complications are difficult to manage with standard therapy. Patients reaching this stage of the disease may benefit from a treatment change from pills to the so-called device-aided therapies. However, there is currently no unanimous definition of advanced PD, which makes it challenging to identify suitable candidates for device-aided therapies. There is urgent need to define specific features (or ‘clinical indicators’) to support healthcare professionals and patients in the identification of advanced PD as well as to define suitability for device-aided therapy. This study aimed to assess the accuracy of 15 clinical indicators and seven device-aided therapy eligibility criteria using information from a large database of 4714 patients in G7 countries. Physicians classified 14.9% of patients as having advanced PD and 17.5% were judged to be eligible for device-aided therapy. Each clinical indicator or device-aided therapy eligibility indicator was detected more frequently in patients classified as having advanced PD and in patients considered eligible for device-aided therapy, respectively. All indicators had high accuracy for identifying advanced PD and device-aided therapy-eligibility. These previously identified clinical indicators of advanced PD and device-aided therapy eligibility may provide an objective and reliable approach for patient screening and treatment optimization.

1435. Unmet Needs in Uncomplicated Urinary Tract Infection in the United States and Germany: A Physician Survey

Background

Uncomplicated urinary tract infections (uUTI) are one of the most common bacterial infections in women. Understanding unmet needs of physicians in diverse healthcare systems is important for developing novel uUTI treatment (tx).

Methods

A cross-sectional survey of physicians in the US and Germany (DE). Physicians were recruited via specialist panel and the survey was piloted (1 US, 1 DE physician) prior to recruitment. Primary objectives were understanding physician tx goals, management approaches, and prescribing patterns for uUTI. Secondary objectives included understanding perceptions of uUTI impact on patients and awareness of antibiotic (AB) resistance. Descriptive statistics were used for analysis. See Table for inclusion/exclusion criteria.

Table. Physician inclusion and exclusion criteria

Results

Overall, 300 physicians (200 US, 100 DE) were surveyed. Symptom relief was in the top 3 (of 5) most important outcomes for ≥ 90% of physicians (US and DE); clearing infection was a top 3 outcome for 85% of US and 60% of DE physicians (Fig. 1). Physicians estimated ~20% of patients do not achieve complete relief from initial AB tx. Generally, urinalysis, dip stick, and symptom review were most commonly used in diagnosis, with culture and AB susceptibility tests mostly used to aid tx decisions (Fig. 2). For first-line AB, US physicians reported trimethoprim-sulfamethoxazole (TMP-SMX; 76%) and nitrofurantoin (57%) as most prescribed; in DE, fosfomycin (61%) and TMP-SMX (50%) were prescribed most. In both countries, ciprofloxacin (US 51%, DE 45%) was most prescribed after ≥ 2 tx failures. On a scale of “very poor” (1) to “exceptional” (7) for tx and management of uUTI, 58% of US physicians gave TMP-SMX a 6 or 7, and 62% of DE physicians gave fosfomycin a 6 or 7. More than 33% of physicians believed patients’ quality of life was greatly impacted by 1 tx failure, rising to 60% of physicians for 2 tx failures, and 73% for ≥ 3. Most physicians (72% US, 83% DE) agreed that development of AB resistance was serious (Fig. 3), but fewer (56% US, 46% DE) were confident in their knowledge of AB resistance.

Figure 1. Treatment goal considered in the top 3 most important goals by physicians for managing patients with uUTI

Conclusion

Symptom relief was the primary uUTI tx goal for physicians. Physicians recognized that patients are greatly impacted by tx failure and AB resistance is a serious problem, but many were not confident or had insufficient information on AB resistance.

The cardiovascular effects of amodiaquine and structurally related antimalarials: An individual patient data meta-analysis

BACKGROUND

Amodiaquine is a 4-aminoquinoline antimalarial similar to chloroquine that is used extensively for the treatment and prevention of malaria. Data on the cardiovascular effects of amodiaquine are scarce, although transient effects on cardiac electrophysiology (electrocardiographic QT interval prolongation and sinus bradycardia) have been observed. We conducted an individual patient data meta-analysis to characterise the cardiovascular effects of amodiaquine and thereby support development of risk minimisation measures to improve the safety of this important antimalarial.

METHODS AND FINDINGS

Studies of amodiaquine for the treatment or prevention of malaria were identified from a systematic review. Heart rates and QT intervals with study-specific heart rate correction (QTcS) were compared within studies and individual patient data pooled for multivariable linear mixed effects regression. The meta-analysis included 2,681 patients from 4 randomised controlled trials evaluating artemisinin-based combination therapies (ACTs) containing amodiaquine (n = 725), lumefantrine (n = 499), piperaquine (n = 716), and pyronaridine (n = 566), as well as monotherapy with chloroquine (n = 175) for uncomplicated malaria. Amodiaquine prolonged QTcS (mean = 16.9 ms, 95% CI: 15.0 to 18.8) less than chloroquine (21.9 ms, 18.3 to 25.6, p = 0.0069) and piperaquine (19.2 ms, 15.8 to 20.5, p = 0.0495), but more than lumefantrine (5.6 ms, 2.9 to 8.2, p < 0.001) and pyronaridine (-1.2 ms, -3.6 to +1.3, p < 0.001). In individuals aged ≥12 years, amodiaquine reduced heart rate (mean reduction = 15.2 beats per minute [bpm], 95% CI: 13.4 to 17.0) more than piperaquine (10.5 bpm, 7.7 to 13.3, p = 0.0013), lumefantrine (9.3 bpm, 6.4 to 12.2, p < 0.001), pyronaridine (6.6 bpm, 4.0 to 9.3, p < 0.001), and chloroquine (5.9 bpm, 3.2 to 8.5, p < 0.001) and was associated with a higher risk of potentially symptomatic sinus bradycardia (≤50 bpm) than lumefantrine (risk difference: 14.8%, 95% CI: 5.4 to 24.3, p = 0.0021) and chloroquine (risk difference: 8.0%, 95% CI: 4.0 to 12.0, p < 0.001). The effect of amodiaquine on the heart rate of children aged <12 years compared with other antimalarials was not clinically significant. Study limitations include the unavailability of individual patient-level adverse event data for most included participants, but no serious complications were documented.

CONCLUSIONS

While caution is advised in the use of amodiaquine in patients aged ≥12 years with concomitant use of heart rate-reducing medications, serious cardiac conduction disorders, or risk factors for torsade de pointes, there have been no serious cardiovascular events reported after amodiaquine in widespread use over 7 decades. Amodiaquine and structurally related antimalarials in the World Health Organization (WHO)-recommended dose regimens alone or in ACTs are safe for the treatment and prevention of malaria.

Agitation in Dementia: Real-World Impact and Burden on Patients and the Healthcare System

Background:

At least 90%of patients with dementia experience behavioral or neuropsychiatric symptoms including agitation, psychotic symptoms, apathy, depression, and sleep disturbances. Agitation has been reported to be experienced by 60%of patients with mild cognitive impairment and 76%of patients with Alzheimer’s disease.

Objective:

We aimed to assess the impact of agitation in patients with dementia on healthcare resource utilization (HCRU) and healthcare costs.

Methods:

This was a retrospective analysis of physician-reported patient data from a point-in-time survey. Patients included were aged≥50 years, with early cognitive impairment or dementia. Agitated and non-agitated patients were compared. Regression analyses assessed the relationship of agitation score (calculated from number/severity of agitation symptoms) with outcomes, with covariates including age and Mini-Mental State Examination score. Sensitivity analyses compared patients with 0 and≥2 agitation symptoms following propensity score matching on the base-case covariates.

Results:

Data were included for 1,349 patients (agitated, n = 693; non-agitated, n = 656). Based on regression analyses, agitation score was correlated with proportion of patients with professional caregivers (p < 0.01), institutionalized (p < 0.01), hospitalized in a psychiatric ward (p < 0.05), and receiving an antipsychotic/antidepressant (both p < 0.001); number of consultations with a healthcare professional (HCP), psychiatrist, or psycho-geriatrician; number and cost of hospitalizations (p < 0.01); cost of HCP consultations (p < 0.001); and total direct healthcare costs (p < 0.001). Sensitivity analyses generally supported the base-case analysis.

Conclusion:

Agitation in dementia is associated with increased HCRU and healthcare costs. Effective therapies are needed to address agitation in dementia, with the potential to alleviate patient impact, HCRU, and healthcare costs.

Impact of Dementia-Related Behavioral Symptoms on Healthcare Resource Use and Caregiver Burden: Real-World Data from Europe and the United States

BACKGROUND

Dementia is commonly accompanied by neurobehavioral symptoms; however, the relationship between such symptoms and health-related outcomes is unclear.

OBJECTIVE

To investigate the impact of specific neurobehavioral symptoms in dementia on healthcare resource use (HCRU), patient quality of life (QoL), and caregiver burden.

METHODS

Data were taken from the 2015/16 Adelphi Real World Dementia Disease Specific Programme™, a point-in-time survey of physicians and their consulting dementia patients. Multiple regression analyses were used to examine associations between patient symptom groups and health-related outcomes.

RESULTS

Each patient symptom group of interest (patients with agitation/aggression and related symptoms [AARS] with psychosis, patients with AARS without psychosis, and patients with other behavioral symptoms) had a positive association with HCRU variables (i.e., HCRU was greater), a negative association with proxy measures of patient QoL (i.e., QoL was decreased), and a positive association with caregiver burden (i.e., burden was greater) compared with patients with no behavioral symptoms (control group). The magnitude of effect was generally greatest in patients with AARS with psychosis. Regression analysis covariates that were found to be most often significantly related to the outcomes were dementia severity and the patients' living situation (i.e., whether they were in nursing homes or living in the community).

CONCLUSION

Combinations of behavioral symptoms, particularly involving AARS plus psychosis, may have a detrimental impact on health-related outcomes such as HCRU, patient QoL, and caregiver burden in dementia. Our results have implications for intervention development in patients who report clusters of symptoms and caregivers, and for identifying at-risk individuals.

Cross-walk of the Assessment of Spondyloarthritis International Society Health Index and Ankylosing Spondylitis Quality of Life Scores in Ankylosing Spondylitis and Non-radiographic Axial Spondyloarthritis Patients

Introduction

Axial spondyloarthritis (axSpA) is a chronic rheumatic disease affecting the spine and sacroiliac joints, encompassing both ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA) patients. Patient quality of life (QoL) is assessed using the Ankylosing Spondylitis Quality of Life (ASQoL) (disease-specific measure) and the Assessment of SpondyloArthritis International Society Health Index (ASAS HI) (disease-specific measure). Both ASQoL and ASAS HI have similar parameters and scoring ranges, however, their performance relative to each other is unknown. We conducted a cross-walk analysis of the ASAS HI to the ASQoL in AS and nr-axSpA patients.

Methods

A cross-sectional survey using the Adelphi axSpA Disease Specific Programme™, conducted with rheumatologists and their consulting AS and nr-axSpA patients in the United States, was undertaken between Jun and Aug 2018. Rheumatologists provided confirmed diagnoses of AS and nr-axSpA alongside patients’ demographic and clinical characteristics. Patients reported quality-of-life measures using the validated ASAS HI and ASQoL questionnaires. Model performance was assessed by comparing root-mean squared error (RMSE) from tenfold cross-validation to determine the best mapping from ASAS HI to ASQoL, and vice versa. RMSE was calculated overall, and for lower, middle and upper thirds of the predicted scale.

Results

Data from 283 AS and 274 nr-axSpA patients were analyzed. Predicting ASAS HI using ASQoL values, the best model was non-parametric local linear regression, with overall RMSE of 1.851. Predicting ASQoL using ASAS HI values, the best model also used non-parametric local-linear regression, with overall RMSE of 2.254. In predicting ASAS HI and ASQoL, models performed better in predicting lower values in the predicted scale (RMSE 1.597, 1.871, 2.871 across thirds for ASAS HI; and 1.719, 2.577, 3.140 for ASQoL).

Conclusions

Results present a scoring algorithm for cross-walking the ASAS HI to the ASQoL and vice versa, with the approach enabling comparisons to be made across studies.

Abstract PS10-47: Physician and patient satisfaction with poly(ADP-ribose) polymerase inhibitors (PARPi) versus chemotherapy in adult patients with germline BRCA1/2 mutated (gBRCA1/2mut) HER2- advanced breast cancer (ABC): Results from a multi-country real-world (RW) study

Background: Within the past 3 years, PARPi have demonstrated improved progression-free survival and favorable PROs compared with chemotherapy in randomized clinical trials in patients with gBRCA1/2mut HER2- ABC. These agents are now available in multiple countries for the treatment of gBRCA1/2mut HER2- locally advanced and/or metastatic breast cancer. Limited information is available on physician/patient satisfaction with PARPi from the RW. We assessed RW physician/patient treatment satisfaction among adult patients with gBRCA1/2mut HER2- ABC in Germany, France, Italy, Spain (EU4), US, and Israel.

Methods: Oncologist were recruited to abstract data from medical records (2019/2020) for patients with gBRCA1/2mut HER2- ABC. Physicians were asked to rank (1=very dissatisfied to 5=very satisfied) their satisfaction with their patient’s current ABC treatment. The scores were dichotomized to a 0/1 variable (0=very dissatisfied/ dissatisfied/moderately satisfied; 1=satisfied/very satisfied). A subset of patients completed the Cancer Treatment Satisfaction Questionnaire, a validated instrument that was used to measure patient’s satisfaction with their current therapy. The physician and patient sample were matched. Physician/patient satisfaction scores were compared between chemotherapy and PARPi monotherapy utilizing inverse probability weighted regression adjustment controlling for age at therapy initiation, Charlson Comorbidity Index at time of data collection, baseline symptoms, hormone receptor (HR) status, ECOG score at therapy initiation, stage of therapy initiation (locally advanced breast cancer or metastatic breast cancer) and number of lines of ABC treatment.

Results: Overall 96 adult female patients participated; mean age was 51 years. Tumor characteristics were: 34.4% HR+/HER2-, 65.6% triple negative breast cancer. Chemotherapy (n=58) was received among 60.4% of pts [n=29 (50.0%) platinum based, n=29 (50.0%) non-platinum based], and PARPi monotherapy (n=38) was received among 39.6% of pts. Physicians were significantly more likely to be satisfied or very satisfied with PARPi in comparison with chemotherapy (95.4% vs. 40.8%, p&lt;0.001). Mean patient satisfactions scores were numerically higher with PARPi vs. chemotherapy: expectation of therapy 81.3 vs. 72.0 (p=0.13), feelings about side effects 55.7 vs. 51.4 (p=0.30), satisfaction with therapy 74.0 vs. 68.5 (p=0.13).

Conclusions: PARPi have demonstrated superior efficacy and favorable PROs vs. chemotherapy in randomized controlled trials. In this RW study, physicians reported significantly higher satisfaction with PARPi vs. chemotherapy; patients reported numerically higher satisfaction scores with PARPi vs. chemotherapy across all domains. These findings further support the value of PARPi in patients with gBRCA1/2mut HER2- ABC. Additional studies to validate these findings are planned.

Abstract PS10-32: Patient reported outcomes (PROs) with poly(ADP-ribose) polymerase inhibitors (PARPi) versus chemotherapy (CTX) in patients (pts) with germline BRCA1/2 mutated (gBRCA1/2mut) HER2- advanced breast cancer (ABC): Results from a multi-country real-world (RW) study

Background: In ABC, where treatment is palliative, an important goal is the maintenance or improvement of quality of life (QoL). In the past 3 years, PARPi have demonstrated improved progression-free survival and favorable PROs compared with CTX in randomized clinical trials (RCTs) in pts with ABC and a gBRCA1/2mut. These agents are now available in multiple countries for the treatment of gBRCA1/2mut HER2- locally advanced and/or metastatic breast cancer. Limited information is available on the PRO benefit of these agents in the RW setting. We assessed RW cancer-related and breast-cancer specific PROs among adult pts with gBRCA1/2mut HER2- ABC in Germany, France, Italy, Spain (EU4), US, and Israel.

Methods: Oncologists were recruited to abstract data from medical records (2019/2020) for pts with gBRCA1/2mut HER2- ABC. A subset of pts completed the European Organisation for Research and Treatment of Cancer Quality of Life Core 30 (EORTC QLQ-C30) and the breast cancer module QLQ-BR23. PROs were compared between CTX and PARPi monotherapy utilizing inverse probability weighted regression adjustment (IPWRA) controlling for age at therapy initiation, Charlson Comorbidity Index at time of data collection, baseline symptoms, hormone receptor (HR) status, ECOG score at therapy initiation, stage of therapy initiation (locally advanced breast cancer or metastatic breast cancer) and number of lines of ABC treatment.

Results: Overall 96 female pts participated; mean age was 51 years. Tumor characteristics were: 34.4% HR+/HER2-, 65.6% triple negative breast cancer. CTX (n=58) was received among 60.4% of pts [n=29 (50.0%) platinum based, n=29 (50.0%) non-platinum based], and PARPi monotherapy (n=38) was received among 39.6% of pts. Compared to pts receiving CTX, pts receiving PARPi reported significantly better scores in physical and social functioning (Table 1). Pts receiving PARPi reported significantly better symptoms scores vs. CTX in constipation, breast symptoms, arm symptoms and systemic therapy side effects (Table 1). Pts receiving PARPi reported significantly worse scores vs. CTX in nausea/vomiting (Table 1). Global health status (GHS)/QoL scores were numerically better among pts receiving PARPi vs. CTX (Table 1).

Conclusions: PARPi have demonstrated superior efficacy and favorable PROs vs. CTX in RCTs in pts with gBRCA1/2mut HER2- ABC. In this RW study, the PRO benefits reported with PARPi were consistent with what has been observed in RCTs, further supporting the value of PARPi. Additional studies to validate these findings are planned.

Real-world assessment of the impact of "OFF" episodes on health-related quality of life among patients with Parkinson's disease in the United States

Background

Many patients with Parkinson’s disease (PD) who receive carbidopa/levodopa experience symptom reemergence or worsening, or “OFF” episodes. This study assessed the association of “OFF” episodes with health-related quality of life (HRQoL).

Methods

US-specific data from the 2017 and 2019 Adelphi Real World Disease Specific Programme for PD, a real-world cross-sectional survey, were used. Neurologists provided data for 10–12 consecutive patients with PD who completed the 39-item Parkinson’s Disease Questionnaire (PDQ-39) and the EuroQol 5-Dimension (EQ-5D). Data were grouped by patients who experienced “OFF” episodes versus those who did not and by average hours of daily “OFF” time. Differences between patient groups were assessed for demographics and clinical characteristics; regression analyses were used to model the relationship between HRQoL and “OFF” episodes with age, sex, body mass index, current PD stage on the Hoehn and Yahr scale, and number of concomitant conditions related and unrelated to mobility as covariates.

Results

Data from 722 patients were analyzed. Overall, 321 patients (44%) had “OFF” episodes (mean of 2.9 h of daily “OFF” time). Patients who experienced “OFF” episodes were less likely to work full-time and more likely to live with family members other than their spouse/partner or reside in a long-term care facility than those without “OFF” episodes. The presence of “OFF” episodes, regardless of the average hours of daily “OFF” time, was significantly associated with high scores (reflecting poor HRQoL) on most PDQ-39 dimensions and the summary index and low scores (reflecting poor health status) on the EQ-5D health utility index, visual analog scale (VAS), and all dimensions. Furthermore, increased average hours of daily “OFF” time was significantly correlated with higher scores for all PDQ-39 dimensions and the summary index, as well as with the EQ-5D health utility index and VAS scores. Patients with “OFF” episodes experienced reduced HRQoL even after correcting for potentially confounding variables.

Conclusions

This study demonstrated that the occurrence of “OFF” episodes in patients with PD is associated with reduced HRQoL and that the impact on HRQoL increased incrementally with increasing average hours of daily “OFF” time.

Real-world assessment of "OFF" episode-related healthcare resource utilization among patients with Parkinson's disease in the United States

AIMS

Within 5 years of initiating carbidopa/levodopa, ∼50% of patients with Parkinson's disease (PD) experience "OFF" episodes; little is known about the cost burden. We investigated the association of "OFF" episodes with patient characteristics, healthcare resource utilization (HCRU), and healthcare costs.

METHODS

Analyses used neurologist-provided data from the US-specific 2017 and 2019 Adelphi Real World Disease Specific Programme for PD, including duration of "OFF" episodes and HCRU for 10-12 consecutive patients. Patients were grouped by presence/absence of "OFF" episodes and by average hours of daily "OFF" time. Between-group differences were assessed for demographics, personal circumstances, and clinical characteristics. Regression analyses modeled the relationship of "OFF" episodes with HCRU and costs.

RESULTS

Of 1,309 patients, 41% experienced "OFF" episodes, 25% of whom were "OFF" ≥4 h/day. Patients having "OFF" episodes had more severe PD, were diagnosed for longer, and were younger than those without "OFF" (p < .0001). "OFF" episodes were associated with a greater number of prescribed PD drugs (p < .0001). Patients without "OFF" episodes were more likely to have full-time employment and less likely to be retired or unemployed because of PD (p < .001). Patients with and without "OFF" episodes had different living situations (p < .001): patients experiencing "OFF" were less likely to live alone and more likely to live in a nursing home and have a professional caregiver (p < .001). In the past 12 months, the number of hospitalizations, intensive care admissions, and emergency room visits; nights hospitalized; costs of consultations and hospitalizations; and total direct costs were all higher for patients experiencing "OFF" episodes (p < .05).

CONCLUSION

Patients with PD and "OFF" episodes had higher HCRU and costs than those without "OFF," suggesting that "OFF" episodes contribute to the economic burden of PD. Further research is warranted to examine the extent that current PD treatments and treatment patterns impact HCRU and costs.

Real-world patient-reported outcomes of women receiving initial endocrine-based therapy for HR+/HER2- advanced breast cancer in five European countries

Background

Endocrine therapy (ET)-based regimens are the mainstay of treatment for patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2−) advanced breast cancer. With the introduction of new treatment classes, it is important to examine patient symptoms and health-related quality of life (HRQoL) at the start of this changing therapeutic landscape. This real-world study describes the patient-reported outcomes (PROs) of women with HR+/HER2− advanced breast cancer receiving ET-based regimens who were naïve to systemic treatment in the advanced setting across five European countries (EU5).

Methods

Data were collected between March and July 2017 from surveyed oncologists and their patients at a single time point using the multinational Adelphi Advanced Breast Cancer Disease Specific Programme™. Patients completed PRO questionnaires on HRQoL (EORTC QLQ-C30), pain severity and interference, and work and activity impairment. A multiple linear regression model explored factors associated with HRQoL.

Results

Across EU5, 226 physicians provided data on 781 women with HR+/HER2− advanced breast cancer taking their first ET-based regimen for advanced disease, of whom 252 provided PRO data. This subset had a mean age of 67.1 years, 94% were postmenopausal, 89% were diagnosed with advanced breast cancer at initial presentation, 79% had stage IV disease (66% of these patients had bone metastases and 38% had visceral metastases, including 18% with liver metastases) and 77% were on endocrine-only therapy as their initial treatment for advanced disease. The mean EORTC QLQ-C30 global health score (50.9) was worse than the reference value for patients with advanced breast cancer (60.2). Fatigue, pain, and insomnia were the most severe symptoms, and mean functioning scores were also worse than reference values. “Worst pain” and “pain interference” were moderate/severe for 42 and 80% of patients. Mean activity impairment was 44%, and greater activity impairment was associated with poorer HRQoL.

Conclusions

Despite receiving first-line ET-based regimens for advanced disease, these women had a poor HRQoL and high levels of symptoms, pain, pain interference and activity impairment. New treatments that maintain a stable disease state and reduce activity impairment may have a positive effect on the HRQoL of those living with advanced breast cancer.

AB1170 THE IMPACT OF HIGH DISEASE ACTIVITY AS MEASURED BY SLEDAI AND DRUG BURDEN-ON HEALTHCARE UTILIZATION, QUALITY OF LIFE AND WORK PRODUCTIVITY IN SYSTEMIC LUPUS ERYTHEMATOSUS PATIENTS

Background:

Although there is abundant literature on healthcare utilization in SLE patients, the impact of disease activity in SLE patients is not well understood.

Objectives:

To quantify the impact of disease activity, as measured by SLEDAI score and drug burden, in SLE patients on health care resource utilization (HCRU), health related quality of life (HRQoL) and work productivity (WP).

Methods:

Data were collected from a cross-sectional survey of 754 rheumatologists in US and EU5 from the Adelphi Real World 2010/2013/2015 Lupus Disease Specific Programmes (DSP). Physicians were asked to complete patient record forms (PRFs) for the next 5 prospectively consulting SLE patients; the same patients were asked to complete patient self-completion (PSC) forms describing how SLE affected them. PRFs collected data pertaining to the patient’s diagnosis, disease history, current clinical outcomes, treatment and management history. PSCs focused on similar data collection and included patient reported outcome measures (PROs). Propensity score matching was used to assess differences in HCRU and PRO scores between SLE patients who had a low disease activity and those who had a high disease activity. Low disease activity was defined as a SLEDAI score of ≤4, a steroid dose of <7.5mg/day, and not on immunosuppressant or biologic. High disease activity was a SLEDAI score of >4, or on an immunosuppressant, biologic, or steroid dose of >7.5mg/day. Patients were matched on age, sex, and ethnicity.

Results:

Data was extracted from 1278 PRFs, and 591 PSCs. Using the estimated propensity score each low disease activity patient (n=44) was matched with a high disease activity patient (n=1187). Using 1:1 matching, with replacement and allowing for ties, matching resulted in 414 high disease activity patients being used as matches for 44 low disease activity patients. Demographic data are reported in Table 1. Patients with a low disease activity were significantly less likely to be currently flaring, lower number of flares in last 12 months, less likely to have been hospitalized in the last 12 months, had fewer consultations in the last 12 months, reported better HrQoL (EQ5D), more favourable levels of fatigue (FACIT), and lower work impairment (WPAI). (Table 2).

Conclusion:

Systemic lupus erythematosus patients with lower levels of disease activity are less burdensome to the healthcare system and experience a significantly better HRQoL and lower levels of productivity impairment. There is a need to establish a universal definition of low disease activity as a treatment goal to benefit patient quality of life and reduce HCRU.

A Novel, Integrative Approach for Evaluating Progression in Multiple Sclerosis: Development of a Scoring Algorithm

Background

There is an unmet need for a tool that helps to evaluate patients who are at risk of progressing from relapsing-remitting multiple sclerosis to secondary progressive multiple sclerosis (SPMS). A new tool supporting the evaluation of early signs suggestive of progression in multiple sclerosis (MS) has been developed. In the initial stage, concepts relevant to progression were identified using a mixed method approach involving regression on data from a real-world observational study and qualitative research with patients and physicians. The tool was drafted in a questionnaire format to assess these variables.

Objective

This study aimed to develop the scoring algorithm for the tool, using both quantitative and qualitative research methods.

Methods

The draft scoring algorithm was developed using two approaches: quantitative analysis of real-world data and qualitative analysis based on physician interviews and ranking and weighting exercises. Variables that were included in the draft tool and regarded as most clinically relevant were selected for inclusion in a multiple logistic regression. The analyses were run using physician-reported data and patient-reported data. Subsequently, a ranking and weighting exercise was conducted with 8 experienced neurologists as part of semistructured interviews. Physicians were presented with the variables included in the draft tool and were asked to rank them in order of strength of contribution to progression and assign a weight by providing a percentage of the overall contribution. Physicians were also asked to explain their ranking and weighting choices. Concordance between physicians was explored.

Results

Multiple logistic regression identified age, MS disease activity, and Expanded Disability Status Scale score as the most significant physician-reported predictors of progression to SPMS. Patient age, mobility, and self-care were identified as the strongest patient-reported predictors of progression to SPMS. In physician interviews, the variables ranked and weighted as most important were stability or worsening of symptoms, intermittent or persistent symptoms, and presence of ambulatory and cognitive symptoms. Across all physicians, the level of concordance was 0.278 (P<.001), indicating a low to moderate, but statistically significant, level of agreement. Variables were categorized as high (n=8), moderate (n=8), or low (n=10) importance based on the findings from the different approaches described above. Accordingly, the respective questions in the tool were assigned a weight of “three,” “two,” or “one” to inform the draft scoring algorithm.

Conclusions

This study further confirms the need for a tool to provide a consistent, comprehensive approach across physicians to support the early evaluation of signs indicative of progression to SPMS. The novel and comprehensive approach to develop the draft scoring algorithm triangulates data obtained from ranking and weighting exercises, qualitative interviews, and a real-world observational study. Variables that go beyond the clinically most obvious impairment in lower limbs have been identified as relevant subtle/sensitive signs suggestive of progressive disease.

The role of negative affect in the persistence of nicotine dependence among alternative high school students: A latent growth curve analysis

BACKGROUND

Previous research has demonstrated how negative affect (i.e., depression, anxiety, stress) is often a correlate of and precursor to nicotine dependence. Although recent evidence shows a gradual decline in tobacco use in the United States, subgroups that report higher levels of negative affect may continue to be at risk of becoming dependent on nicotine. One high-risk subgroup is students who attend alternative high schools. The current longitudinal investigation examined the effect of negative affect on nicotine dependence in this youth population.

METHODS

1060 students from 29 alternative high schools in Southern California completed a series of attitudinal and behavioral measures once per year over a three-year period. The main outcome was nicotine dependence i.e., feeling a strong urge to use nicotine products or experiencing withdrawal symptoms after a period of abstinence, measured using a version of the Fagerstrom Tolerance Questionnaire designed for adolescents. A latent growth curve model was utilized to examine the effect of negative affect on nicotine dependence during this timeframe.

RESULTS

The analysis revealed that negative affect had both a concurrent and prospective relationship with nicotine dependence. Moreover, the association between negative affect and nicotine dependence in the present was not statistically significant once the influence of negative affect reported one year earlier was accounted for.

CONCLUSIONS

Negative affect may play a critical role in the persistence of nicotine dependence among high-risk youth. Providing resources to help manage negative affect may be critical to curtailing nicotine dependence in this population.

Age-varying associations between e-cigarette use and peer use, household use, and exposure to e-cigarette commercials among alternative high school students in Southern California

INTRODUCTION

Electronic cigarettes (e-cigarettes) have rapidly become the most commonly used tobacco product among youth in the United States. Exposure to advertising, peer use, and household use, increases the risk of current e-cigarette use; however, the influence of these factors may be dynamic across adolescence. The aim of this study is to examine the age-varying associations between e-cigarette use and peer use, household use, and exposure to e-cigarette commercials among alternative high school students in Southern California.

METHODS

Using data previously collected for a tobacco marketing study, we examine the age-varying associations of current e-cigarette use and three risk factors (peer use, exposure to commercials, and household use) across ages 15 to 20 years using time-varying effect modeling (TVEM). Analyses include three waves of data from alternative high school students (N=1060 students; 2036 observations).

RESULTS

The probability of e-cigarette use gradually increased over the age of 15 years and then decreased by the age of 17 years for females and after the age of 18 years for males. Significant gender differences were observed between the ages of 17 and 19.5 years. Peer e-cigarette use was associated with higher odds of current e-cigarette use across all ages for females and after the age of 16 years for males. Exposure to e-cigarette commercials increased current use significantly for males between the ages of 16 and 18 years. Household use increased the odds of current use of e-cigarettes between the ages of 17 and 19 years for males and under 16.5 and over 18 years for females.

CONCLUSIONS

The findings highlight the utility of TVEM in understanding the risk factors of e-cigarette use and suggest that these factors are dynamic across adolescence.

Working Memory and Response Inhibition Effects on At-Risk Youth's Willingness to Use Multiple Nicotine and Tobacco Products

Purpose: Past research has suggested that executive functions, such as working memory and response inhibition, predict the use of nicotine and tobacco products (NTPs). The current study extends prior research by assessing whether response inhibition and working memory are associated with at-risk youth's willingness to use NTPs. Methods: A sample of 1060 at-risk youth were recruited from alternative high schools in southern California. Participants were randomly assigned to complete the Symmetry Span Task, an indicator of working memory ability, or the cued Go/No-Go task, an indicator of response inhibition. Participants who reported never using NTPs (n = 348) indicated how willing they would be try NTPs. Results: Results from a cross-sectional zero-inflated negative binomial (ZINB) regression suggest that females with stronger working memory skills and individuals with weaker response inhibition skills were more likely to be unwilling to use NTPs. Conclusion: While further research is needed to determine whether executive functions can prospectively predict NTP use among at-risk youth, the current study indicates that both working memory and response inhibition may play a significant role.

A mixed methods approach towards understanding key disease characteristics associated with the progression from RRMS to SPMS: Physicians' and patients' views

OBJECTIVES

The transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive multiple sclerosis (SPMS) evolves over time and it can be challenging for physicians to identify progression early. Typically, SPMS is diagnosed retrospectively with a significant delay, based on a history of gradual worsening, independent of relapses, following an initial relapsing-remitting disease course. As such, SPMS is often associated with a considerable period of diagnostic uncertainty. This study aimed to explore and characterize key symptoms and impacts associated with transitioning from RRMS to SPMS and inform the content for a tool to support evaluation of early subtle signs suggestive of progressive disease.

METHODS

The qualitative study involved 60-min, face-to-face, concept elicitation (CE) interviews with 32 patients with MS (US = 16 and Germany = 16); and 30-min, telephone, CE interviews with 16 neurologists (US = 8 and Germany = 8). Multivariate analysis on data from a real-world observational study of 3294 MS patients assessed the differences between early-RRMS and early-SPMS, and identified factors that were significant drivers of this difference. These studies informed selection of the key variables to be included in a pilot tool. Sixteen physicians used the pilot tool, presented as a paper questionnaire, with a sample of patients whom they suspected were progressing to SPMS (n ≥ 5). Following this, the physicians participated in a 30-min cognitive debriefing (CD) interview to evaluate the relevance and usefulness of the tool. Qualitative analysis of all anonymized, verbatim transcripts was performed using thematic analysis.

RESULTS

Patients and physicians reported signs that indicated progression to SPMS including gradual worsening of symptoms, lack of clear recovery, increased severity and presence of new symptoms. No specific symptoms definitively indicated progression to SPMS, however a number of potential symptoms associated with progression were identified by SPMS patients and physicians, including worsening ambulation, cognition, balance, muscle weakness, visual symptoms, bladder symptoms and fatigue. Quality of life domains reported to be more severely impacted in SPMS than MS in general included: physical activity, work, daily activities, emotional and social functioning. Multivariate analysis of the observational study data identified several variables strongly associated with progression to SPMS including, requirement of assistance in daily living, presence of motor symptoms, presence of ataxia/coordination symptoms, and unemployment. Physicians reported that items included in the tool were easy to understand and relevant. Physicians also reported that there is an unmet need for a tool to help identify signs of SPMS progression and so the tool would be useful in clinical practice.

CONCLUSIONS

This was the first stage of development of a novel, validated, physician-completed tool to support physician-patient interactions in evaluating signs indicative of disease progression to SPMS. Qualitative and quantitative methods (involving physician and patients) were used to determine tool content. The usefulness and unmet need for such a tool in clinical practice was confirmed via CD interviews with physicians. Further work is now warranted to develop a scoring algorithm and validate the tool so that it can be reliably implemented in clinical practice.

2485. Real-world Experience with Dolutegravir Plus Rilpivirine Two-Drug Regimen

Background

Three-drug regimens (3DRs) have long been the mainstay of antiretroviral treatment (ART) for HIV. Dolutegravir-based two-drug regimens (DTG 2DRs) are now accepted alternatives to 3DRs, with the first 2DR single tablet regimen (STR), Juluca (DTG/rilpivirine [RPV]), FDA-approved in 2017. This study evaluated treatment patterns of DTG+RPV in clinical practice to understand use prior to availability of DTG/RPV STR.

Methods

A retrospective medical chart review was conducted across 10 US sites identified as using any DTG 2DRs. Eligible patients were adults initiated on DTG 2DR prior to July 31, 2017 and followed up to January 30, 2018. This analysis describes a subgroup who received DTG+RPV 2DR. Patient demographics, clinical characteristics and treatment history were abstracted from medical charts. Analyses were descriptive.

Results

From an overall sample of 278 DTG 2DR patients, 66 received DTG+RPV 2DR. In this DTG+RPV subgroup, mean age was 56 years, 79% were male and 68% were Caucasian. Most were treatment-experienced (97%), with an average 15.5 years of prior ART; 48% had received ≥ 4 prior regimens. The most common physician reported reasons for initiating DTG+RPV were avoidance of potential long-term toxicities (53%), toxicity/intolerance of ARVs (20%) and treatment simplification/streamlining (15%). Prior to initiation of DTG+RPV, 70% of patients were virologically suppressed (< 50 copies/mL); of those, 98% remained suppressed after switching to DTG+RPV. Of the 30% of patients with detectable viral load prior to DTG+RPV initiation, 60% achieved and maintained virologic suppression on DTG+RPV. Mean time on DTG+RPV was 1.6 years. Only 5 (8%) patients discontinued DTG+RPV by data cut-off, and one patient was lost to follow-up. Reasons for discontinuation were virologic failure (n = 2), treatment simplification/streamlining (n = 2) and toxicity/intolerance (n = 1). Physicians reported that most patients (91%) achieved the desired outcome from DTG+RPV use.

Conclusion

Prior to commercial availability of DTG/RPV STR in the United States, DTG+RPV was used primarily in treatment experienced patients, most commonly to avoid potential long-term toxicities. A high proportion of patients achieved the desired outcome and maintained virologic suppression while receiving DTG+RPV.

Treatment patterns in patients with acute myeloid leukemia in the United States: a cross-sectional, real-world survey

OBJECTIVE

The aim of this analysis was to examine treatment patterns in patients with acute myeloid leukemia (AML) in routine clinical practice in the United States, including factors influencing the choice of front-line treatment intensity and the effect of age and treatment line.

METHODS

We used data from the Adelphi AML Disease Specific Programme, a real-world, cross-sectional survey conducted in 2015. Physicians completed patient record forms providing patients' demographic and clinical characteristics.

RESULTS

In total, 61 academic, non-academic, and office-based hematologists and hematology/oncology specialists provided data on 457 patients with AML; 284 had ≥20% blasts (World Health Organization defined AML) and were included in the analysis. In the front-line setting, 60% of patients received high-intensity therapy, most commonly cytarabine plus anthracycline; the most common low-intensity treatments were hypomethylating agents. Primary drivers for selecting high-intensity versus low-intensity treatment were age, performance status and comorbidities; 67%, 64% and 61% of physicians stated they would prescribe high-intensity treatment to patients aged <65 years, with good performance status or no comorbidities, respectively. In practice, patients aged <60 years were more likely to receive high-intensity induction treatment (high vs. low intensity by age p < .0001). In a selected cohort of relapsed/refractory patients, 69% of patients received high-intensity therapy (78% of patients aged <60 years and 57% of patients aged ≥60 years).

CONCLUSIONS

Most patients in this analysis of real-world survey data received well established, front-line induction therapies. Treatment intensity was determined by age, comorbidities and performance status, as recommended by guidelines.

Real-World Impact of Physician and Patient Discordance on Health-Related Quality of Life in US Patients with Acute Myeloid Leukemia

Introduction

There is limited understanding concerning the health-related quality of life (HRQoL) in acute myeloid leukemia (AML) patients. Due to an overlap of symptoms, it can be difficult to separate disease versus treatment-related effects. Study objectives were to understand the impact of factors that might influence patients’ HRQoL, assess the degree of concordance in symptom reporting by patients and physicians, and assess the impact of any discordance on HRQoL in AML patients.

Methods

Physicians in the USA captured demographics, current AML treatment and symptoms for 82 AML patients who completed the Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu), 5-Dimension EuroQol Questionnaire (EQ-5D-3L) and Cancer Treatment Satisfaction Questionnaire (CTSQ). Effect size (ES) and clinically meaningful differences between AML subgroups were assessed, as was the impact of disagreement between patients and physicians regarding symptom recognition.

Results

Clinically meaningful lower overall FACT-Leu scores were observed for: relapsed/refractory versus non-relapsed/refractory AML patients (92.5 vs. 103.7; P = 0.09; ES = 0.439), hypomethylating agent (HMA) monotherapy versus other therapies in patients with low treatment intensity (89.9 vs. 112.9; P = 0.0021; ES = 0.971) and presence/absence of FLT3-ITD mutation (85.5 vs. 100; P = 0.148; ES = 0.816). Differences in health state were also clinically meaningful between patients with/without FLT3-ITD; EQ-5D-Visual Analog Scale (VAS) (47.6 vs. 63.7; P = 0.0428; ES = 0.816). Patients were more likely than physicians to report bruising (κ = 0.1292), fatigue (κ = 0.0836), bleeding (κ = 0.0177), weight loss (κ = 0.0821) and appetite loss (κ = − 0.0246). FACT-Leu was associated with patient-physician discordance on bleeding (difference − 14.12; P = 0.046), weight loss (− 21.22; P = 0.001) and appetite loss (− 12.58; P = 0.027).

Conclusions

HRQoL is generally low for AML patients, especially for particular subgroups. Discordance in symptom reporting between patients and physicians was common and associated with further negative impacts on HRQoL. There may be many reasons for this but better communication between physicians and patients may lead to shared objectives and improvement in patients’ HRQoL.

OR26-4 Genome-Wide Binding Profile of Phosphorylated Estrogen Receptor Reveals Association with Direct DNA Binding

Post-translational modifications are key regulators of protein function, providing signals that alter protein interactions and activity. Phosphorylation of estrogen receptor-α (ER) at serine 118 (pS118-ER) occurs in response to multiple stimuli and is involved in modulating ER-dependent gene transcription. While the effects of pS118 on ER-DNA interactions have been investigated at specific genomic sites, the genome-wide binding profile (cistrome) of pS118-ER remains to be studied. To determine and characterize the pS118-ER cistrome, chromatin immunoprecipitation sequencing (ChIP-seq) was performed on both pS118-ER and ER and their binding profiles were compared. A subset of ER sites was found to be occupied by pS118-ER and although these sites were not found to be enriched in promoter regions relative to all ER sites, the pS118-ER sites were associated with the active enhancer mark H3K27ac as well as genes upregulated, but not downregulated, by estrogen. Additionally, pS118-ER sites were found to be enriched in the DNA binding motif for GRHL2 as well as the estrogen response element (ERE) relative to all ER sites. Utilizing a DNA binding microarray, pS118-ER was found to be more commonly associated with direct DNA binding events compared to indirect binding events. These results suggest a role for pS118-ER at active enhancers and as a regulator of direct ER-DNA interactions. Prevention of this phosphorylation event could serve as a potential treatment for ER-positive breast cancers by reducing the transcriptional activity of ER and decreasing its occupancy on DNA.

Factor VII Antigen Levels in a Healthy Blood Donor Population

We determined factor VII antigen (FVIIag) levels in 705 healthy blood donors ranging in age from 17 to 79 years using a two-site solid-phase enzyme immunoassay developed in our laboratory. The mean (± SD) FVIIag level for the total population was 102 ± 31%. FVIIag levels for men (n = 375) and women (n = 330) were 101 ± 28% and 103 ± 33%, respectively. A significant increase in FVIIag was observed with age in both men (r = 0.25, p <0.0001) and women (r = 0.35, p <0.0001). FVIIag levels were significantly higher in women > 60 years when compared to men (median women: 125%; median men: 111%; p <0.05). On a subset of the study group (n = 45), FVIIag levels were correlated to total cholesterol (r = 0.27, p = 0.08) and triglyceride (r = 0.41, p <0.01). Assuming the commonly used reference interval of 60-140% for FVII, the frequencies of FVIIag values for <60% and >140% using our assay were 2.1% and 9.2%, respectively. Gender and age-related differences in FVIIag levels must be considered in a reference interval. We further suggest that assay-specific reference ranges be established, which may include values outside the commonly used values of 60-140%.

Design and Development of a Mobile System for Supporting Emergency Triage

Objectives: Our objective was to design and develop a mobile clinical decision support system for emergency triage of different acute pain presentations. The system should interact with existing hospital information systems, run on mobile computing devices (handheld computers) and be suitable for operation in weak-connectivity conditions (with unstable connections between mobile clients and a server).

Methods: The MET (Mobile Emergency Triage) system was designed following an extended client-server architecture. The client component, responsible for triage decision support, is built as a knowledge-based system, with domain ontology separated from generic problem solving methods and used for the automatic creation of a user interface.

Results: The MET system is well suited for operation in the Emergency Department of a hospital. The system’s external interactions are managed by the server, while the MET clients, running on handheld computers are used by clinicians for collecting clinical data and supporting triage at the bedside. The functionality of the MET client is distributed into specialized modules, responsible for triaging specific types of acute pain presentations. The modules are stored on the server, and on request they can be transferred and executed on the mobile clients. The modular design provides for easy extension of the system’s functionality. A clinical trial of the MET system validated the appropriateness of the system’s design, and proved the usefulness and acceptance of the system in clinical practice.

Conclusions: The MET system captures the necessary hospital data, allows for entry of patient information, and provides triage support. By operating on handheld computers, it fits into the regular emergency department workflow without introducing any hindrances or disruptions. It supports triage anytime and anywhere, directly at the point of care, and also can be used as an electronic patient chart, facilitating structured data collection.

Development of an Online Smoking Cessation Curriculum for Pacific Islanders: A Community-Based Participatory Research Approach

BACKGROUND

Pacific Islanders (PIs) have one of the highest rates of cigarette use, but evidence-based smoking cessation programs designed specifically for PIs are practically nonexistent.

OBJECTIVES

This paper reports on the development of a culturally tailored smoking cessation curriculum designed specifically for young adult PIs using a community-based participatory research (CBPR) approach. This paper demonstrates the shared leadership and equal contribution of community and academic partnerships.

METHODS

Together community and academic partners conceptualized and developed a smoking cessation curriculum. Data from formative studies shaped the various components of the educational modules.

RESULTS

Eight educational modules were developed through CBPR. Information on the dangers of cigarettes, benefits to cessation, and ways to cope with cravings and stress through cognitive behavioral therapy were offered in both narrative and non-narrative formats.

CONCLUSIONS

Use of CBPR is critical in the development of the curriculum because it allowed for the sharing of ideas and knowledge between academics and community members.

The prevalence and marketing of electronic cigarettes in proximity to at-risk youths: An investigation of point-of-sale practices near alternative high schools

This study examines the point-of-sale marketing practices used to promote electronic cigarettes at stores near schools that serve at-risk youth. One hundred stores selling tobacco products within a half mile of alternative high schools in Southern California were assessed for this study. Seventy percent of stores in the sample sold electronic cigarettes. Convenience stores heavily frequented by youth had the highest number of interior ads for e-cigarettes and were the most likely to employ in-store product placement strategies. Increased exposure to the promotion of these products at the point-of-sale poses a challenge for anti-smoking efforts directed toward vulnerable populations.

Real-World Impact of Cardiovascular Disease and Anemia on Quality of Life and Productivity in Patients with Non-Dialysis-Dependent Chronic Kidney Disease

INTRODUCTION

Patients with chronic kidney disease (CKD) have an increased risk of comorbid conditions, including cardiovascular disease (CVD). Anemia is prevalent in the CKD population and worsens as kidney function declines, resulting in a diminished quality of life and increased morbidity/mortality. The purpose of this secondary analysis was to determine the real-world prevalence of CVD among patients with non-dialysis-dependent CKD (NDD-CKD), with and without comorbid anemia, and to assess the impact of these conditions on quality of life (QoL) and work productivity.

METHODS

Data were drawn from the Adelphi CKD Disease-Specific Programme, conducted in France, Germany, Italy, Spain, and the UK (2012). Anonymized data were collected via patient record forms and patient-completed questionnaires. Patient data were stratified by anemic status and the presence of CVD comorbidity.

RESULTS

Data were collected by physicians for 1993 patients, of whom 867 completed a patient-completed questionnaire. A total of 61.4% of patients had anemia, and the prevalence of anemia increased with CKD stage. Patients with anemia had a higher mean number of cardiovascular comorbidities than non-anemic patients (1.27 vs 0.95, respectively; P < 0.001). The presence of cardiovascular conditions was associated with a significantly reduced QoL (EuroQol EQ-5D-3L visual analog scale: coefficient, -5.68 in anemic patients; P = 0.028) and work productivity and activity impairment (WPAI activity impairment: coefficient, +8.04 in anemic patients; P = 0.032), particularly among anemic patients.

CONCLUSIONS

The presence of anemia in this cohort of NDD-CKD patients was high. The presence of concomitant cardiovascular conditions was more common in NDD-CKD patients with comorbid anemia, and was associated with reduced QoL and work productivity outcomes.

Negative affect in at-risk youth: Outcome expectancies mediate relations with both regular and electronic cigarette use

Despite the general trend of declining use of traditional cigarettes among young adults in the United States, alternative high school students continue to smoke cigarettes and electronic cigarettes at rates much higher than do students attending regular high schools. Challenging life circumstances leading to elevated levels of negative affect may account for increased smoking behavior in this population. Further, a belief in the negative affect-reducing qualities of nicotine may mediate this effect. The current study tested the hypothesis that negative reinforcing outcome expectancies mediate the relationship between negative affect on smoking susceptibility in nonusers, smoking frequency in users, and smoking experimentation in the overall sample. Results support the hypothesis that negative affect in alternative high school students is correlated with smoking experimentation, smoking willingness, and smoking frequency and that the relationship between negative affect and smoking behavior outcomes is mediated by negative reinforcing outcome expectancies (i.e., beliefs in the negative affect-reducing effects of smoking). This finding was supported for both cigarettes and electronic cigarettes and coincides with a rapid increase in the number of high school students nationally who have experimented with electronic cigarettes. Future antismoking initiatives directed at at-risk youth should consider integrating healthier negative affect reduction techniques to counter the use of nicotine products. (PsycINFO Database Record

Misalignment between physicians and patient satisfaction with psoriatic arthritis disease control

The main objective of the present study is to evaluate the misalignment between psoriatic arthritis (PsA) patient- and physician-reported satisfaction with PsA control. Data came from the Adelphi Rheumatology Disease Specific Programme, a retrospective, cross-sectional survey of US-based rheumatologists and patients. Physicians provided satisfaction and clinical characteristics on tender joint count, swollen joint count, and percent body surface area (BSA) affected by psoriasis. Patients provided data on satisfaction, the Work Productivity Activity Impairment and Health Assessment Questionnaire-Disability Index (HAQ-DI) questionnaires. Based on their satisfaction response, patient-physician pairs were classified into aligned (both satisfied or dissatisfied) or misaligned (rated satisfaction differently) groups. Multivariate analysis evaluated association of characteristics with misalignment. Among 305 paired patient-physician records analyzed, 23.6% were misaligned and 76.4% were aligned. The misaligned group had shorter disease duration (mean years, 5.2 vs. 6.4), used fewer biologic disease-modifying antirheumatic drugs (49.3 vs. 62.9%), had more swollen (mean, 3.7 vs. 1.9, P = 0.0002) and tender joints (mean, 5.6 vs. 2.9, P < 0.0001), greater proportion of patients with comorbidities (72.2 vs. 63.1%), and >3% BSA affected by psoriatic skin lesions (64.2 vs. 55.1%). Misaligned patients reported greater work impairment (mean, 38.7 vs. 21.4, P = 0.0004), daily activities (mean, 38.7 vs. 22.3, P < 0.0001), and higher disease burden (mean HAQ-DI; 0.56 vs. 0.37, P = 0.0001). Multivariate analysis found the number of swollen joints (P = 0.02) and HAQ-DI score (P = 0.03) was significantly associated with misalignment among all patients; however, not in the subgroup of employed patients. Patient-physician misalignment is associated with increased disease activity and disability among patients with PsA.
