Associations of weight loss with obesity-related comorbidities in a large integrated health system.

AIMS: To determine the health outcomes associated with weight loss in individuals with obesity, and to better understand the relationship between disease burden (disease burden; ie, prior comorbidities, healthcare utilization) and weight loss in individuals with obesity by analysing electronic health records (EHRs). MATERIALS AND METHODS: We conducted a case-control study using deidentified EHR-derived information from 204 921 patients seen at the Cleveland Clinic between 2000 and 2018. Patients were aged ≥20 years with body mass index ≥30 kg/m2 and had ≥7 weight measurements, over ≥3 years. Thirty outcomes were investigated, including chronic and acute diseases, as well as psychological and metabolic disorders. Weight change was investigated 3, 5 and 10 years prior to an event. RESULTS: Weight loss was associated with reduced incidence of many outcomes (eg, type 2 diabetes, nonalcoholic steatohepatitis/nonalcoholic fatty liver disease, obstructive sleep apnoea, hypertension; P < 0.05). Weight loss >10% was associated with increased incidence of certain outcomes including stroke and substance abuse. However, many outcomes that increased with weight loss were attenuated by disease burden adjustments. CONCLUSIONS: This study provides the most comprehensive real-world evaluation of the health impacts of weight change to date. After comorbidity burden and healthcare utilization adjustments, weight loss was associated with an overall reduction in risk of many adverse outcomes.

Exploring Why People With Type 2 Diabetes Do or Do Not Persist With Glucagon-Like Peptide-1 Receptor Agonist Therapy: A Qualitative Study.

OBJECTIVE: Despite the demonstrated benefits of glucagon-like peptide 1 (GLP-1) receptor agonist therapy, adherence and persistence with this therapy is often challenging. The purpose of this study was to expand current understanding of patients' experiences, motivations, and challenges relevant to their persistence with GLP-1 receptor agonist therapy. DESIGN AND METHODS: This noninterventional, cross-sectional, qualitative study used face-to-face interviews with 36 adults with type 2 diabetes who had been treated with at least one GLP-1 receptor agonist medication. Inclusion criteria were: ≥18 years of age, diagnosed with type 2 diabetes, and currently treated with a GLP-1 receptor agonist for ≥1 month at the time of screening ("continuers") or discontinued use of a GLP-1 receptor agonist ≤1 year of screening but with a total ≥1 month of treatment ("discontinuers"). Interviews were conducted using a semi-structured qualitative interview guide that included open-ended questions and probes to obtain both spontaneous and prompted input from participants about their current and past treatment experiences with GLP-1 receptor agonist therapy. RESULTS: Among continuers (n = 16), the most commonly identified facilitators supporting the decision to continue were the observations of improved glucose control (50%) and weight loss (55%). Among discontinuers (n = 20), the most commonly identified challenges leading to treatment discontinuation were side effects (55%) and high cost (50%). Continuers were more likely than discontinuers to receive clinically relevant information from their health care team, including facts about GLP-1 receptor agonist medications, likely treatment benefits, the importance of gradual dose titration, and the need to adjust diet after initiation. CONCLUSION: Although cost is a major obstacle to treatment continuation, it can only be resolved through changes in ongoing reimbursement coverage and policies. However, many other obstacles could potentially be addressed (e.g., reducing side effects with gradual dosage titration and setting appropriate expectations regarding efficacy) through more collaborative patient-clinician interactions before initiating therapy.

Factors associated with pain severity, pain interference, and perception of functional abilities independent of joint status in US adults with hemophilia: Multivariable analysis of the Pain, Functional Impairment, and Quality of Life (P-FiQ) study.

INTRODUCTION: Levels of pain and dysfunction appear to differ among people with hemophilia despite similar levels of joint disease. OBJECTIVE: To determine patient characteristics that influence pain and function independent of joint status. METHODS: US adults with hemophilia completed a survey that included information on clinical characteristics, demographics, and patient-reported outcome instruments assessing pain (Brief Pain Inventory v2 Short Form [BPI]), functional impairment (Hemophilia Activities List [HAL]), and health status (EQ-5D-5L). Additionally, physiotherapists optionally completed a clinical joint evaluation (Hemophilia Joint Health Score [HJHS]). Associations were examined using simple and multiple regression models. RESULTS: Of 381 adults enrolled, 240 had complete HJHS scores (median age, 32 years). After controlling for HJHS and opiate use, anxiety/anxiolytic use was significantly associated with worse pain severity and interference scores. After controlling for HJHS, the most significant predictors of functional impairment were older age, unemployment, more severe hemophilia, and greater pain. EQ-5D-5L pain/discomfort was associated with worse outcomes on most HAL scores. CONCLUSION: Unemployment, anxiety, and depression were each associated with both greater pain and functional disability after controlling for joint status. Continued attention to pain and psychosocial issues will be important in improving clinical care and research efforts in the hemophilia population.

Reliability and validity of patient-reported outcome instruments in US adults with hemophilia B and caregivers in the B-HERO-S study.

OBJECTIVE: To assess the reliability and validity of six patient-reported outcomes (PRO) instruments for evaluating health-related quality of life in adults with mild-severe hemophilia B and caregivers of children with hemophilia B, including affected women/girls. METHODS: Adults with hemophilia B and caregivers completed separate online surveys containing several PRO instruments, which were administered to adult participants only (EQ-5D-5L, Brief Pain Inventory v2 Short Form, Hemophilia Activities List, and International Physical Activities Questionnaire), both adults and caregivers (Patient Health Questionnaire [PHQ-9]), or caregivers only (Generalized Anxiety Disorder 7-Item [GAD-7] scale). Construct validity and item-total correlation were assessed using Pearson product-moment correlation, internal consistency was assessed using Cronbach's alpha coefficient, and known-group validity was assessed by comparisons to self-reported characteristics based on the Kruskal-Wallis test. RESULTS: Patient-reported outcomes instruments generally showed satisfactory reliability for adults (n = 299) and caregivers (n = 150). In adults, PRO instruments generally showed high construct validity. Most PRO instruments showed expected significant differences among known groups for adults and caregivers. PHQ-9 and GAD-7 did not show significant differences among caregiver age groups. CONCLUSIONS: Patient-reported outcomes instruments administered in B-HERO-S demonstrated reliability and validity in the broader population of adults with hemophilia B and caregivers when including all severities and genders.

Patient-reported outcomes and joint status across subgroups of US adults with hemophilia with varying characteristics: Results from the Pain, Functional Impairment, and Quality of Life (P-FiQ) study.

INTRODUCTION: Pain and functional impairment associated with joint disease are major problems for people with hemophilia, and impact on health-related quality of life (HRQoL) may vary across groups defined by demographic and treatment-related characteristics. OBJECTIVE: To evaluate differences in overall HRQoL, pain, function, and joint status between P-FiQ study subgroups. METHODS: Adult males with hemophilia and a history of joint pain/bleeding completed a pain history and the patient-reported outcome instruments EQ-5D-5L, Brief Pain Inventory v2 Short Form (BPI), International Physical Activity Questionnaire (IPAQ), and Hemophilia Activities List (HAL); optionally, joint status was assessed (Hemophilia Joint Health Score v2.1 [HJHS]). Scores were analyzed between subgroups across sets of participant characteristics. RESULTS: A total of 381 adult males with hemophilia were enrolled, with median age of 34 years. Worse scores on EQ-5D-5L index, BPI pain severity/interference, HAL overall score, and HJHS were generally associated with being college educated, unemployment, self-reporting both acute and chronic pain, and self-reporting anxiety/depression. CONCLUSIONS: Measures of joint status and HRQoL were consistently lower in participants who had higher educational levels, were unemployed, self-reported having both acute and chronic pain, and self-reported having anxiety/depression. A greater understanding of the association of these factors with disease outcomes may improve individualized patient management.

Impact of hemophilia B on quality of life in affected men, women, and caregivers-Assessment of patient-reported outcomes in the B-HERO-S study.

INTRODUCTION: Health-related quality of life (HRQoL) is impaired in patients with hemophilia; however, the impact in mild/moderate hemophilia B and affected women is not well characterized. OBJECTIVE: To evaluate factors that affect HRQoL in adults with hemophilia B and caregivers of affected children. METHODS: US adult patients and caregivers of affected children completed distinct ~1-hour online surveys including patient-reported outcome instruments. RESULTS: In total, 299 adult patients and 150 caregivers participated. Adults with moderate hemophilia reported poorer health status (median EQ-5D-5L index score, 0.63) than those with mild (0.73) or severe (0.74) hemophilia. Women reported greater pain severity than men on the Brief Pain Inventory v2 Short Form (median, 7.00 vs 5.00). Based on the Patient Health Questionnaire, mild or worse depression was observed in >50% of adult respondents, and depression was reported more often in those with moderate and severe hemophilia vs those with mild hemophilia. Most caregivers reported at least mild depression. CONCLUSION: Pain, functional impairment, and depression/anxiety are present at higher-than-expected levels in individuals with hemophilia B. The large proportion of individuals with mild/moderate hemophilia and women with reduced health status suggests significant unmet needs in this population.

Impact of mild to severe hemophilia on engagement in recreational activities by US men, women, and children with hemophilia B: The Bridging Hemophilia B Experiences, Results and Opportunities into Solutions (B-HERO-S) study.

The psychosocial impact of hemophilia on activities was recently investigated in the Hemophilia Experiences, Results and Opportunities (HERO) study (675 people with hemophilia and 561 caregivers of children with hemophilia in 10 countries). The impact of hemophilia B may not be accurately reflected in the HERO results, as ~75% of respondents described issues affecting males with hemophilia A. To address the needs of this population, the Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) was developed as a pilot study in the United States in collaboration with the hemophilia community. The analysis reported here assessed engagement in recreational activities and changes to treatment regimens around activities as reported by 299 adults with hemophilia B and 150 caregivers of children with hemophilia B. Nearly all adults with hemophilia B (98%) experienced a negative impact on their participation in recreational activities due to hemophilia-related issues, and most caregivers (90%) reported that hemophilia B had a negative impact on their child's engagement in recreational activities. One of the main reasons identified for discontinuing past activities was the risk of bruising or bleeding (adults/children with hemophilia B, 49%/41%). In particular, adults with hemophilia B reported a history of activity-related bleeding, and most adults decreased their participation in high-risk activities as they aged. Substantial percentages of adults and children with hemophilia B (including mild/moderate severity) altered their treatment regimens to accommodate planned activities. These findings may help inform guidelines for individualizing treatment regimens around participation in recreational activities based on hemophilia severity, baseline factor level, and activity risk and intensity.

Management of US men, women, and children with hemophilia and methods and demographics of the Bridging Hemophilia B Experiences, Results and Opportunities into Solutions (B-HERO-S) study.

The Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) initiative was launched in an effort to address specific gaps in the understanding of the psychosocial impact of mild-moderate-severe hemophilia B. The original Hemophilia Experiences, Results and Opportunities (HERO) qualitative study evaluated the needs of people with hemophilia A or B in multiple countries; however, a majority of participants had the more common moderate-severe hemophilia A. The B-HERO-S study was designed in collaboration with the hemophilia community to evaluate the needs of adults with hemophilia B and caregivers of children with hemophilia B, including affected women and caregivers of girls with hemophilia. The report presented here describes participant demographics and comorbidities, as well as treatment regimens and access to treatment. Bleeding symptoms were reported by 27% of mothers of children with hemophilia B who participated. Women were more likely than men to self-report arthritis and depression/anxiety as comorbidities associated with hemophilia B. More adults and children with hemophilia B were on routine treatment than on on-demand treatment, and a high percentage of adults with moderate hemophilia B received routine treatment (86%). Many adults with hemophilia B (78%) and caregivers (69%) expressed concern about access to factor in the next 5 years, and of adults with hemophilia B, women more commonly experienced issues with access to factor in the past than did men (72% vs 44%). The findings of the B-HERO-S study reveal potential unmet needs of some patients with mild-moderate hemophilia B, and the results may be leveraged to inform patient outreach by hemophilia treatment centers and education initiatives.

Unmet needs in the transition to adulthood: 18- to 30-year-old people with hemophilia.

Young adults with hemophilia face unique challenges during the transition to adulthood, including issues associated with switching from pediatric to adult hematology care, building mature interpersonal relationships, and establishing an independent career with an assurance of medical insurance coverage. A greater understanding of these challenges is essential for developing effective strategies to address the specific needs of this population. These challenges may be differentiated from those of older adults with hemophilia in large part because of more extensive childhood prophylaxis and safer factor products, resulting in fewer joint problems and lower rates of HIV and HCV infections. This analysis of the changing nature and unmet needs of today's young adults entering into adult hemophilia treatment centers, as well as potential strategies for optimally addressing these needs, was developed following roundtable discussions between patients, caregivers, hematologists, and other health care professionals participating in comprehensive care. Challenges identified among young adults with hemophilia include psychosocial issues related to maturity, personal responsibility, and increased independence, as well as concerns regarding when and with whom to share information about one's hemophilia, limited awareness of educational and financial resources, and a low perceived value of regular hematology care. The initiatives proposed herein highlight important opportunities for health care professionals at pediatric and adult hemophilia treatment centers, as well as national organizations, community groups, and career counselors, to address key unmet needs of this patient population.

Glucose-lowering treatment patterns in patients with diabetic kidney disease.

OBJECTIVES: Recent trials of glucose-lowering drugs (GLDs) have drawn attention to renal outcomes. Our goal was to understand how patients with diabetic kidney disease (DKD) are treated in general practices in the United States. STUDY DESIGN: Retrospective cohort study using a national-level claims data set and electronic health records. METHODS: Patients (≥ 18 years) with type 2 diabetes, whose estimated glomerular filtration rates (eGFRs) were between 15 and 89 mL/min/1.73 m2 between 2016 and 2018, were selected. Use of different GLDs during a 12-month period was examined across all eGFR levels. RESULTS: Of the 25,486 sample patients, 69.2%, 18.9%, 9.6%, and 2.3% had an eGFR in the ranges of 60 to 89, 45 to 59, 30 to 44, and 15 to 29 mL/min/1.73 m2, respectively. Metformin was used by nearly 33% of patients with an eGFR of 30 to 44 mL/min/1.73 m2 and by 10% of patients with an eGFR less than 30 mL/min/1.73 m2. Less than 10% (across all eGFR levels) of patients used glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors. Use of insulin was more frequent among patients with a lower eGFR (P < .05). The findings were similar in subgroups with different hemoglobin A1c levels (< 7% and ≥ 7%). CONCLUSIONS: Real-world treatment of DKD in the United States is suboptimal. Inappropriate use of some GLD classes, especially in advanced DKD stages, was found along with lower than expected use of modern agents that are considered safe and effective to treat glycemic outcomes. Efforts may be needed to improve understanding of safety, glycemic efficacy, and overall clinical value of GLDs across DKD stages.

Impact of Sustained Weight Loss on Cardiometabolic Outcomes.

Obesity increases the risk of developing type 2 diabetes, hypertension, and hyperlipidemia. We sought to determine the impact of obesity maintenance, weight regain, weight loss maintenance, and magnitudes of weight loss on future risk and time to developing these cardiometabolic conditions. This was a retrospective cohort study of adults receiving primary care at Geisinger Health System between 2001 and 2017. Using electronic health records, patients with ≥3-weight measurements over a 2-year index period were identified and categorized. Obesity maintainers (OM) had obesity (body mass index ≥30 kg/m²) and maintained their weight within ±3% from baseline (reference group). Both weight loss rebounders (WLR) and weight loss maintainers (WLM) had obesity at baseline and lost >5% body weight in year 1; WLR regained ≥20% of weight loss by end of year 2 and WLM maintained ≥80% of weight loss. Incident type 2 diabetes, hypertension, and hyperlipidemia, and time-to-outcome were determined for each study group and by weight loss category for WLM. Of the 63,567 patients included, 67% were OM, 19% were WLR, and 14% were WLM. The mean duration of follow-up was 6.6 years (SD, 3.9). Time until the development of electronic health record-documented type 2 diabetes, hypertension, and hyperlipidemia was longest for WLM and shortest for OM (log-rank test p <0.0001). WLM had the lowest incident type 2 diabetes (adjusted hazard ratio [HR] 0.676 [95% confidence interval [CI] 0.617 to 0.740]; p <0.0001), hypertension (adjusted HR 0.723 [95% CI 0.655 to 0.799]; p <0.0001), and hyperlipidemia (adjusted HR 0.864 [95% CI 0.803 to 0.929]; p <0.0001). WLM with the greatest weight loss (>15%) had a longer time to develop any of the outcomes compared with those with the least amount of weight loss (<7%) (p <0.0001). In an integrated delivery network population, sustained weight loss was associated with a delayed onset of cardiometabolic diseases, particularly with a greater magnitude of weight loss.

Cardiovascular Disease in Patients With Type 2 Diabetes: A Qualitative Analysis of Knowledge, Attitudes, and Beliefs of Health Care Professionals.

Guidelines for the management of patients with type 2 diabetes mellitus (T2DM) recommend SGLT-2 (sodium-glucose cotransporter 2) inhibitors and GLP-1 RAs (glucagon-like peptide 1 receptor agonists) as second-line agents for patients with, or at risk for, cardiovascular disease. A better understanding of guideline implementation will further the provision of evidence-based health care to patients. Interviews and surveys of clinicians were conducted to understand providers' knowledge, attitudes, and beliefs related to the 2019 American Diabetes Association Standards of Care for T2DM. There was a lack of widespread knowledge of the guidelines and comfort with their use. Clinicians require additional training and education on the efficacy of the new medications and accompanying clinical guidelines.

Effects of sustained weight loss on outcomes associated with obesity comorbidities and healthcare resource utilization.

OBJECTIVE: Determine the impact of long-term non-surgical weight loss maintenance on clinical relevance for osteoarthritis, cancer, opioid use, and depression/anxiety and healthcare resource utilization. METHODS: A cohort of adults receiving primary care within Geisinger Health System between 2001-2017 was retrospectively studied. Patients with ≥3 weight measurements in the two-year index period and obesity at baseline (BMI ≥30 kg/m2) were categorized: Obesity Maintainers (reference group) maintained weight within +/-3%; Weight Loss Rebounders lost ≥5% body weight in year one, regaining ≥20% of weight loss in year two; Weight Loss Maintainers lost ≥5% body weight in year one, maintaining ≥80% of weight loss. Association with development of osteoarthritis, cancer, opioid use, and depression/anxiety, was assessed; healthcare resource utilization was quantified. Magnitude of weight loss among maintainers was evaluated for impact on health outcomes. RESULTS: In total, 63,567 patients were analyzed including 67% Obesity Maintainers, 19% Weight Loss Rebounders, and 14% Weight Loss Maintainers; median follow-up was 9.7 years. Time until osteoarthritis onset was delayed for Weight Loss Maintainers compared to Obesity Maintainers (Logrank test p <0.0001). Female Weight Loss Maintainers had a 19% and 24% lower risk of developing any cancer (p = 0.0022) or obesity-related cancer (p = 0.0021), respectively. No significant trends were observed for opioid use. Weight loss Rebounders and Maintainers had increased risk (14% and 25%) of future treatment for anxiety/depression (both <0.0001). Weight loss maintenance of >15% weight loss was associated with the greatest decrease in incident osteoarthritis. Healthcare resource utilization was significantly higher for Weight Loss Rebounders and Maintainers compared to Obesity Maintainers. Increased weight loss among Weight Loss Maintainers trended with lower overall healthcare resource utilization, except for hospitalizations. CONCLUSIONS: In people with obesity, sustained weight loss was associated with greater clinical benefits than regained short-term weight loss and obesity maintenance. Higher weight loss magnitudes were associated with delayed onset of osteoarthritis and led to decreased healthcare utilization.

Hemophilia without prophylaxis: Assessment of joint range of motion and factor activity.

BACKGROUND: Recurrent joint bleeding in hemophilia results in arthropathy and functional impairment. The relationship of arthropathy development and factor activity (FA) has not been reported in patients with FA levels <15%-20%. METHODS: During the Centers for Disease Control and Prevention Universal Data Collection, joint range-of-motion (ROM) measurements were taken at each comprehensive visit. Data were extracted from male patients with hemophilia (PWH) age ≥2 years with baseline factor activity levels ≤40%, excluding those prescribed prophylaxis, and used to calculate a proportion of normal ROM (PN-ROM) measure. Data were analyzed using regression models. RESULTS: There were 6703 eligible PWH with 30 102 visits. PN-ROM declined with increasing age, and was associated with hemophilia severity, race/ethnicity, obesity, and viral illnesses. PWH ≥30 years old with fFA ≤2% and those ≥50 years old with FA ≤5% had mean PN-ROM values >10% less than controls; those ≥40 years old with FA <1% had values >20% less than controls. In the multivariable analysis, subjects with <1% FA had a 0.43% greater decrease (-0.49 to -0.37, 95% confidence interval) in PN-ROM each year relative to those with 16%-40% factor activity. A less pronounced effect was seen with 1%-5% or 6%-9% FA. CONCLUSION: The effect of FA on ROM loss is far greater than that of any of the other characteristics, especially with FA <10%. This emphasizes the need to maintain a high index of suspicion for arthropathy in individuals with moderate and low-mild hemophilia.

Impact of Weight Change in Adults with Type 2 Diabetes Mellitus: A Literature Review and Critical Analysis.

OBJECTIVE: Weight reduction is a key component of diabetes management in adults with type 2 diabetes mellitus (T2DM), yet the benefits of weight loss in T2DM patients have been difficult to quantify. We examined the medical literature regarding the relationships between weight change and 1) glycemic control and 2) cost and resource use. METHODS: Systematic searches were conducted in the electronic databases Embase, MEDLINE, and the Cochrane Database of Systematic Reviews to identify publications regarding the impact of weight change on T2DM outcomes from 2007 onward. Identified publications were screened for relevance against predefined eligibility criteria, and methodological approaches and results were extracted. Evidence for the impact of weight change on outcomes was evaluated and used to identify strengths, limitations, and gaps in the current literature. RESULTS: The number of studies meeting eligibility criteria for each outcome was: glycemic control (n=38) and cost and resource use (n=11). The relationship between weight change and glycemic control was dependent on the interplay of multiple factors, eg, the weight loss interventions employed, the antidiabetic medication classes used, the time horizon, and baseline BMI and glycemic control. With respect to cost and resource use, the review indicated that savings were associated with weight loss, and increased costs were associated with weight gain. CONCLUSION: Studies regarding weight change in T2DM patients demonstrated varying effects on glycemic control and a positive association with costs and resource use, where weight loss was associated with decreased costs and resource use. Future studies may be able to clarify these relationships.

Healthcare Costs of Diabetes and Microvascular and Macrovascular Disease in Individuals with Incident Type 2 Diabetes Mellitus: A Ten-Year Longitudinal Study.

OBJECTIVE: The objective of this study was to estimate the incremental long-term costs associated with T2DM attributable to vascular diseases. RESEARCH DESIGN AND METHODS: This retrospective cohort study identified newly diagnosed (incident) T2DM patients in 2007 (baseline to 01/01/2006) using the HealthCore Integrated Research Database, a repository of nationally representative claims data. Incident T2DM patients were 1:1 exact matched on age, gender and other factors of interest to non-DM patients, and followed until the earlier of 8 follow-up years or death. Patients with documented vascular disease diagnosis were identified during the study period. All-cause and T2DM/vascular disease-related annual healthcare costs were examined for each follow-up year. RESULTS: The study included 13,883 individuals with T2DM and matched non-DM controls. Among individuals with T2DM, 11,792 (85%) had vascular disease versus 9251 (66.6%) non-T2DM between 01/01/2006 and 12/31/2015. Among T2DM patients, mean all-cause annual costs were greater than in non-T2DM patients ($13,806 vs $7,243, baseline, $21,745 vs $8,524, post-index year 1, $12,756-$14,793 vs $8,349-$9,940 years 2-8, p< 0.001), respectively. A similar trend was observed for T2DM/vascular disease-related costs (p< 0. 001). T2DM/vascular disease-related costs were largest during post-index year 1, accounting for the majority of all-cause cost difference between T2DM patients and matched non-DM controls. Incident T2DM individuals without vascular disease at any time had significantly lower costs compared to non-DM controls (p< 0. 001) between years 2-8 of follow-up. CONCLUSION: Vascular disease increased the cost burden for individuals with T2DM. The cost impact of diabetes and vascular disease was highest in the year after diagnosis, and persisted for at least seven additional years, while the cost of T2DM patients without vascular disease trended lower than for matched non-DM patients. These data highlight potential costs that could be offset by earlier and more effective detection and management of T2DM aimed at reducing vascular disease burden.

Correction to: A Relative Cost of Control Analysis of Once-Weekly Semaglutide Versus Exenatide Extended-Release and Dulaglutide for Bringing Patients to HbA1c and Weight Loss Treatment Targets in the USA.

The article "A Relative Cost of Control Analysis of Once-Weekly Semaglutide Versus Exenatide Extended-Release and Dulaglutide for Bringing Patients to HbA1c and Weight Loss Treatment Targets in the USA", written by Pierre Johansen, Barnaby Hunt, Neeraj N. Iyer, Tam Dang-Tan, Richard F. Pollock was originally published electronically on the publisher's internet portal (currently SpringerLink) on November 27, 2018 without Open Access.

A Relative Cost of Control Analysis of Once-Weekly Semaglutide Versus Exenatide Extended-Release and Dulaglutide for Bringing Patients to HbA1c and Weight Loss Treatment Targets in the USA.

INTRODUCTION: The SUSTAIN 3 and 7 clinical trials compared the efficacy and safety of once-weekly semaglutide relative to exenatide extended-release (ER) and dulaglutide, respectively, in the treatment of patients with type 2 diabetes (T2D). The trials included a series of clinically relevant single and composite endpoints focused on improving glycemic control and reducing body weight, while avoiding hypoglycemia. The present study combined SUSTAIN 3 and 7 outcomes with short-term treatment costs to evaluate the relative cost of control of once-weekly semaglutide versus exenatide ER and dulaglutide. METHODS: Proportions of patients reaching three endpoints were taken from SUSTAIN 3 and 7 for comparisons with exenatide ER and dulaglutide, respectively. The endpoints investigated were HbA1c < 7.0%, HbA1c < 7.0% without hypoglycemia or weight gain, and a ≥ 1.0% HbA1c reduction with ≥ 5.0% weight loss. Annual per patient treatment costs were based on US wholesale acquisition costs from July 2018. Relative cost of control was calculated by plotting the ratio of the treatment costs and the ratio of the proportions of patients reaching each endpoint on the cost-efficacy plane. RESULTS: Once-weekly semaglutide 0.5 mg and 1.0 mg were most effective at bringing patients to each of the three endpoints across both SUSTAIN trials. The efficacy-to-cost ratios for once-weekly semaglutide 0.5 mg and 1.0 mg were also superior to all comparators when assessing both the single endpoint of HbA1c < 7.0% and the two composite endpoints including weight loss and hypoglycemia. CONCLUSIONS: The present study showed that once-weekly semaglutide 0.5 mg and 1.0 mg offer superior cost of control versus exenatide ER and dulaglutide in terms of achieving single and composite endpoints, based on an analysis of retrieved dropout data. Once-weekly semaglutide 0.5 mg and 1.0 mg would therefore represent good value for money in the USA, particularly in the attainment of multi-model T2D treatment goals. FUNDING: Novo Nordisk A/S.

Injectable Antihyperglycemics: A Systematic Review and Critical Analysis of the Literature on Adherence, Persistence, and Health Outcomes.

INTRODUCTION: Improving real-world medication adherence to injectable antihyperglycemics in type 2 diabetes mellitus (T2DM) is a clinical challenge. Quantification of the level of adherence required to achieve a minimal clinically important difference (MCID) in glycemic control would assist in meeting this goal. The study objective was to review the literature regarding the relationships of medication adherence and persistence with health outcomes in adult T2DM patients using injectable antihyperglycemics. METHODS: Systematic searches were conducted using electronic databases to identify publications over the last decade. Publications were screened against established eligibility criteria. Study data were extracted, evaluated, and used to identify strengths, limitations, and gaps in current evidence. RESULTS: Eligibility criteria were met by 38 studies, and this report analyzed 34 studies related to glycemic control (n = 25), healthcare resource use (n = 9), and healthcare costs (n = 14). Eight of these studies examined adherence to glucagon-like peptide-1 receptor agonists (GLP-1 RA), including 1 study regarding adherence to GLP-1 RA or to insulin, and 1 study investigating a GLP-1 RA/insulin combination; the remaining studies involved insulin. Studies used a broad range of measures to classify adherence and persistence, and most measures were unable to reliably evaluate the complexities of patient behavior over time. Better adherence to injectable antihyperglycemic medications was generally found to be associated with improved glycemic control, although no studies attempted to identify a MCID. Although higher diabetes-related pharmacy and total healthcare costs were reported for adherent or persistent patients, these patients tended to have lower diabetes-related and all-cause medical costs. CONCLUSION: Results of this review confirmed the effectiveness of injectable antihyperglycemic medications for glycemic control, suggesting that there are clinical and financial consequences to nonadherence. Although attempts were made to quantify the effects of nonadherence, the interpretation of study results was limited by the lack of a MCID and inadequate study design.

Correlations between patient-reported outcomes and self-reported characteristics in adults with hemophilia B and caregivers of children with hemophilia B: analysis of the B-HERO-S study.

PURPOSE: Pain, anxiety, depression, and other aspects of health-related quality of life (HRQoL) are important issues for people with hemophilia and caregivers of children with hemophilia. Patient-reported outcome (PRO) instruments may be used to assess aspects of HRQoL; however, the use of PROs in clinical management of patients with hemophilia is limited and inconsistent. The Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) study evaluated the impact of hemophilia B on HRQoL and other psychosocial aspects in affected adults and caregivers of children with hemophilia B. This post hoc analysis assessed correlations between PRO scores and psychosocial questions commonly asked in comprehensive care settings among B-HERO-S respondents. PATIENTS AND METHODS: B-HERO-S consisted of two online surveys, one administered to adults with hemophilia B (n=299) and one administered to caregivers of children with hemophilia B (n=150). The adult survey included EQ-5D-5L with visual analog scale, BPI, HAL, and PHQ-9. The caregiver survey included PHQ-9 and GAD-7. Questions related to demographics, hemophilia treatment, and psychosocial questions asked in comprehensive care visits were also included in the surveys. A post hoc analysis was performed to assess correlations between responses to selected psychosocial questions with PRO scores. RESULTS: For adults with hemophilia B, greater pain severity and pain interference scores were associated with work-related problems, functional limitations, and relationship, psychological, and treatment issues. Significant correlations were also noted between some of these psychosocial outcomes and depressive symptoms. For caregivers, greater depression and anxiety were associated with employment issues, their child's functional, relationship, and psychological issues, having had difficulty or concerns with treatment/factor availability or affordability, and having less frequent HTC visits. CONCLUSION: High correlations were observed between PRO scores measuring pain, depression, and anxiety and questions commonly used in the comprehensive care setting to assess the psychosocial impact of hemophilia.
