Racial and Ethnic Disparities in Antihypertensive Medication Prescribing Patterns and Effectiveness. Clin Pharmacol Ther 2024.

Abstract
Variability in drug effectiveness and provider prescribing patterns have been reported in different racial and ethnic populations. We sought to evaluate antihypertensive drug effectiveness and prescribing patterns among self-identified Hispanic/Latino (Hispanic), Non-Hispanic Black (Black), and Non-Hispanic White (White) populations that enrolled in the NIH All of Us Research Program, a US longitudinal cohort. We employed a self-controlled case study method using electronic health record and survey data from 17,718 White, Hispanic, and Black participants who were diagnosed with essential hypertension and prescribed at least one of 19 commonly used antihypertensive medications. Effectiveness was determined by calculating the reduction in systolic blood pressure measurements after 28 or more days of drug exposure. Starting systolic blood pressure and effectiveness for each medication were compared for self-reported Black, Hispanic, and White participants using adjusted linear regressions. Black and Hispanic participants were started on antihypertensive medications at significantly higher SBP than White participants in 13 and 7 out of 19 medications, respectively. More Black participants were prescribed multiple antihypertensive medications (58.46%) than White (52.35%) or Hispanic (49.9%) participants. First-line HTN medications differed by race and ethnicity. Following the 2017 American College of Cardiology and the American Heart Association High Blood Pressure Guideline release, around 64% of Black participants were prescribed a recommended first-line antihypertensive drug compared with 76% of White and 82% of Hispanic participants. Effect sizes suggested that most antihypertensive drugs were less effective in Hispanic and Black, compared with White, participants, and statistical significance was reached in 6 out of 19 drugs. These results indicate that Black and Hispanic populations may benefit from earlier intervention and screening and highlight the potential benefits of personalizing first-line medications.

Factors Involved in Anti-VEGF Treatment Decisions for Neovascular Age-Related Macular Degeneration: Insights from Real-World Clinical Practice. Clin Ophthalmol 2024; 18:1679-1690. [PMID: 38860119 PMCID: PMC11164198 DOI: 10.2147/opth.s461846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 05/21/2024] [Indexed: 06/12/2024] Open
Abstract
Background Anti-vascular endothelial growth factor (anti-VEGF) agents are widely prescribed for the treatment of neovascular age-related macular degeneration (nAMD). Although studies have investigated patient choice of anti-VEGF agent, little is known regarding factors that influence physician preference of anti-VEGF agent for their patients. Objective To describe physician rationale and challenges in prescribing anti-VEGF treatments for patients with nAMD. Methods Data were drawn from the Adelphi Real World nAMD Disease Specific Programme™, a cross-sectional survey with retrospective data capture of physicians and their patients with nAMD in the United States between October 2021 and May 2022. Physicians (n = 56) reported data for up to 13 consecutively consulting patients (n = 451), including current anti-VEGF treatments used, factors affecting physicians' choice of anti-VEGF agent and treatment strategy, and restrictions on specific agents. Results Most physicians prefer employing a "treat-and-extend" treatment strategy, over "fixed interval" or "pro re nata" strategies. However, in routine clinical practice, "treat-and-extend" was reported for less than half of nAMD-diagnosed eyes. Top factors influencing physician choice of anti-VEGF agent and treatment strategy included maximizing clinical benefit (eg visual acuity gains and fluid control), patient convenience, and reducing out-of-pocket costs. However, physicians also reported facing substantial roadblocks in prescribing their choice of anti-VEGF agent, including restrictions on approved agents and gaps in insurance coverage. Persistent fluid was the most common physician-selected reason for switching a patient away from an anti-VEGF agent. Conclusion Physicians face barriers to prescribing their preferred anti-VEGF agents in real-world healthcare settings. Overcoming these challenges may improve treatment outcomes for patients with nAMD.

Abstract
BACKGROUND Limited real-world data exists on clinical outcomes in systemic lupus erythematosus (SLE) patients by SLE Disease Activity Index 2000 (SLEDAI-2 K), hereafter, SLEDAI. We aimed to examine the association between SLEDAI score and clinical, patient-reported and economic outcomes in patients with SLE. METHODS Rheumatologists from the United States of America and Europe provided real-world demographic, clinical, and healthcare resource utilization (HCRU) data for SLE patients. Patients provided self-reported outcome data, capturing their general health status using the EuroQol 5-dimension 3-level questionnaire (EQ-5D-3 L), health-related quality of life using the Functional Assessment of Chronic Illness Therapy (FACIT) and work productivity using the Work Productivity and Activity Impairment questionnaire (WPAI). Low disease activity was defined as SLEDAI score ≤ 4 and ≤ 7.5 mg/day glucocorticoids; patients not meeting these criteria were considered to have "higher" active disease. Data were compared between patients with low and higher disease activity. Logistic regression estimated a propensity score for SLE based on demographic and clinical characteristics. Propensity score matched analyses compared HCRU, patient-reported outcomes, income loss and treatment satisfaction in patients with low disease activity versus higher active disease. RESULTS Data from 296 physicians reporting on 730 patients (46 low disease activity, 684 higher active disease), and from 377 patients' self-reported questionnaires (24 low disease activity, 353 higher active disease) were analyzed. Flaring in the previous 12 months was 2.6-fold more common among patients with higher versus low active disease. Equation 5D-3 L utility index was 0.79 and 0.88 and FACIT-Fatigue scores were 34.78 and 39.79 in low versus higher active disease patients, respectively, indicating better health and less fatigue, among patients with low versus higher active disease. Absenteeism, presenteeism, overall work impairment, and total activity impairment were 47.0-, 2.0-, 2.6- and 1.5-fold greater in patients with higher versus low disease activity. In the previous 12 months there were 28% more healthcare consultations and 3.4-fold more patients hospitalized in patients with higher versus low disease activity. CONCLUSION Compared to SLE patients with higher active disease, patients with low disease activity experienced better health status, lower HCRU, less fatigue, and lower work productivity impairment, with work absenteeism being substantially lower in these patients.

Abstract
OBJECTIVE Chronic spontaneous urticaria (CSU) is a debilitating inflammatory skin condition, often impacting quality of life. International guidelines recommend omalizumab, an anti-immunoglobulin E antibody, for second-line treatment. Our objective was to understand patient characteristics associated with prescription of omalizumab, and assess real-world outcomes in patients with CSU treated with omalizumab. METHODS We analyzed data from the Adelphi Real World CSU Disease Specific Programme, a cross-sectional survey with retrospective data collection (December 2020-October 2021) from physicians and patients with CSU in the United States. RESULTS Data from allergists (n = 45), dermatologists (n = 51), and primary care physicians (PCPs; n = 20) were included. At the time of data collection, one-third of patients were receiving omalizumab (n = 220) and 67% were eligible for but not receiving omalizumab (n = 455). Using logistic regression, the odds of receiving omalizumab were higher in patients whose entire bodies were affected by hives [odds ratio (OR) = 2.551; 95% confidence interval (CI) 1.502-4.333; p < 0.001] or with deteriorating/unstable prognoses at treatment initiation [OR = 2.219; 95% CI 1.031-4.777; p = 0.042], and lower in patients managed by PCPs [OR = 0.276; 95% CI 0.130-0.584; p < 0.001]. Estimates from an inverse probability weighted regression adjustment model indicated that patients receiving omalizumab had higher treatment satisfaction, improvements in itching, hives, angioedema, insomnia, and anxiety, and lower impact on work productivity, compared with patients not receiving omalizumab. CONCLUSION Around two-thirds of patients with CSU considered eligible for omalizumab were not receiving the guideline-recommended therapy. Patients receiving omalizumab had better real-world outcomes compared with patients not receiving omalizumab. Ensuring patients receive the most appropriate treatment could benefit patients with CSU.

Abstract
People with amyotrophic lateral sclerosis (pALS) require complex, multi-disciplinary care, resulting in extensive healthcare resource utilization (HCRU). To investigate the relationship between HCRU and ALS progression, the study objectives were (i) to characterize HCRU in pALS and (ii) to establish whether this varied according to disease stage, as defined using three different methodologies: neurologist-defined early/mid/late stage, the King's clinical staging system for ALS, and the Milan Torino Staging system for ALS (MiToS). Real-world data were drawn from the Adelphi ALS Disease-Specific Programme™, a point-in-time survey of neurologists in France, Germany, Italy, Spain, the UK, and the USA conducted July 2020-March 2021. The analysis included survey responses from 142 physicians with respect to 880 pALS. With advancing ALS stage, significant differences were observed in the number of healthcare professional consultations and X-rays per person (both p < 0.05 for all staging systems), and the proportion of pALS with emergency room admissions, intensive care unit admissions, and assisted ventilation (all p < 0.05 for all staging systems). Across stages, >55% of pALS received care from a general neurologist and a general/primary care practitioner. With increasing stage, there was a significant difference in the proportion receiving care from a physical therapist, pulmonologist/respiratory care practitioner, respiratory therapist, speech/language therapist, and palliative care team, and in the proportion receiving care only from professional caregivers (all p < 0.05 for all staging systems). This study confirmed the substantial HCRU required to support pALS through all stages of ALS and highlighted an increasing need for healthcare resources as the disease progresses.

Abstract
The past decade of population research for diabetes has seen a dramatic proliferation of the use of real-world data (RWD) and real-world evidence (RWE) generation from non-research settings, including both health and non-health sources, to influence decisions related to optimal diabetes care. A common attribute of these new data is that they were not collected for research purposes yet have the potential to enrich the information around the characteristics of individuals, risk factors, interventions, and health effects. This has expanded the role of subdisciplines like comparative effectiveness research and precision medicine, new quasi-experimental study designs, new research platforms like distributed data networks, and new analytic approaches for clinical prediction of prognosis or treatment response. The result of these developments is a greater potential to progress diabetes treatment and prevention through the increasing range of populations, interventions, outcomes, and settings that can be efficiently examined. However, this proliferation also carries an increased threat of bias and misleading findings. The level of evidence that may be derived from RWD is ultimately a function of the data quality and the rigorous application of study design and analysis. This report reviews the current landscape and applications of RWD in clinical effectiveness and population health research for diabetes and summarizes opportunities and best practices in the conduct, reporting, and dissemination of RWD to optimize its value and limit its drawbacks.

Interventions and management on multimorbidity: An overview of systematic reviews. Ageing Res Rev 2023; 87:101901.

Abstract
BACKGROUND Multimorbidity poses an immense burden on the healthcare systems globally, whereas the management strategies and guidelines for multimorbidity are poorly established. We aim to synthesize current evidence on interventions and management of multimorbidity. METHODS We searched four electronic databases (PubMed, Embase, Web of Science, and the Cochrane Database of Systematic Reviews). Systematic reviews (SRs) on interventions or management of multimorbidity were included and evaluated. The methodological quality of each SR was assessed by the AMSTAR-2 tool, and the quality of evidence on the effectiveness of interventions was assessed by the grading of recommendations assessment, development and evaluation (GRADE) system. RESULTS A total of 30 SRs (464 unique underlying studies) were included, including 20 SRs of interventions and 10 SRs summarizing evidence on management of multimorbidity. Four categories of interventions were identified: patient-level interventions, provider-level interventions, organization-level interventions, and combined interventions (combining the aforementioned two or three- level components). The outcomes were categorized into six types: physical conditions/outcomes, mental conditions/outcomes, psychosocial outcomes/general health, healthcare utilization and costs, patients' behaviors, and care process outcomes. Combined interventions (with patient-level and provider-level components) were more effective in promoting physical conditions/outcomes, while patient-level interventions were more effective in promoting mental conditions/outcomes and psychosocial outcomes/general health. As for healthcare utilization and care process outcomes, organization-level and combined interventions (with organization-level components) were more effective. The challenges in the management of multimorbidity at the patient, provider and organizational levels were also summarized. CONCLUSION Combined interventions for multimorbidity at different levels would be favored to promote different types of health outcomes. Challenges exist in the management at the patient, provider, and organization levels. Therefore, a holistic and integrated approach of patient-, provider- and organization- level interventions is required to address the challenges and optimize care of patients with multimorbidity.

Abstract
Abstract
Background and objectives
Defining the optimal moment to start renal replacement therapy (RRT) in acute kidney injury (AKI) remains challenging. Multiple randomized controlled trials (RCTs) addressed this question whilst using absolute criteria such as pH or serum potassium. However, there is a need for identification of the most optimal cut-offs of these criteria. We conducted a causal analysis on routinely collected data (RCD) to compare the impact of different pre-specified dynamic treatment regimes (DTRs) for RRT initiation based on time-updated levels of potassium, pH, and urinary output on 30-day ICU mortality.
Design, setting, participants, and measurements
Patients in the ICU of Ghent University Hospital were included at the time they met KDIGO-AKI-stage ≥ 2. We applied inverse-probability-of-censoring-weighted Aalen–Johansen estimators to evaluate 30-day survival under 81 DTRs prescribing RRT initiation under different thresholds of potassium, pH, or persisting oliguria.
Results
Out of 13,403 eligible patients (60.8 ± 16.8 years, SOFA 7.0 ± 4.1), 5622 (63.4 ± 15.3 years, SOFA 8.2 ± 4.2) met KDIGO-AKI-stage ≥ 2. The DTR that delayed RRT until potassium ≥ 7 mmol/l, persisting oliguria for 24–36 h, and/or pH < 7.0 (non-oliguric) or < 7.2 (oliguric) despite maximal conservative treatment resulted in a reduced 30-day ICU mortality (from 12.7% [95% CI 11.9–13.6%] under current standard of care to 10.5% [95% CI 9.5–11.7%]; risk difference 2.2% [95% CI 1.3–3.8%]) with no increase in patients starting RRT (from 471 [95% CI 430–511] to 475 [95% CI 342–572]). The fivefold cross-validation benchmark for the optimal DTR resulted in 30-day ICU mortality of 10.7%.
Conclusions
Our causal analysis of RCD to compare RRT initiation at different thresholds of refractory low pH, high potassium, and persisting oliguria identified a DTR that resulted in a decrease in 30-day ICU mortality without increase in number of RRTs. Our results suggest that the current criteria to start RRT as implemented in most RCTs may be suboptimal. However, as our analysis is hypothesis generating, this optimal DTR should ideally be validated in a multicentric RCT.

Abstract
OBJECTIVE The external validity of randomised controlled trials (RCTs) and their transferability to clinical practice is under investigated. This study aimed to analyse the exclusion criteria of recent carotid RCTs comparing carotid endarterectomy (CEA) and carotid artery stenting, and to assess the eligibility of consecutive clinical practice cohorts to those RCTs. METHODS An analysis of the clinical and anatomical exclusion criteria of RCTs for asymptomatic (SPACE-2, ACST-2, CREST-1, and CREST-2) and symptomatic carotid stenosis (SPACE-1, CREST-1, ICSS, and EVA-3S) was performed. Two hundred consecutive asymptomatic and 200 consecutive symptomatic patients, treated by CEA, or transfemoral or transcarotid artery stenting at a tertiary referral university centre were assessed for their potential eligibility for each corresponding RCT. RCT patient data were pooled and differences from the clinical practice cohort analysed. Statistics were descriptive and comparative using Fisher's exact and t tests. RESULTS The number of clinical and anatomical exclusion criteria differed widely between RCTs. Potential eligibility rates of the clinical practice cohort for RCTs with regard to asymptomatic carotid stenosis were 80.5% (ACST-2), 79.5% (SPACE-2), 47% (CREST-1), and 20% (CREST-2). For RCTs on symptomatic carotid stenosis the eligibility rates were 89% (ICSS), 86.5% (EVA-3S), 64% (SPACE-1), and 39% (CREST-1). Both clinical practice cohorts were older by about three years and patients were more often male vs. the RCTs. Furthermore, a history of smoking (asymptomatic patients), hypertension (symptomatic patients), and atrial fibrillation was diagnosed more often, whereas hypercholesterolaemia and coronary heart disease (asymptomatic patients) were less prevalent. More clinical practice patients were on antiplatelets, anticoagulants, and lipid lowering drugs. Symptomatic clinical practice patients presented more often with retinal ischaemia and less often with minor hemispheric strokes than patients in the RCTs. CONCLUSION The external validity of contemporary carotid RCTs varies considerably. Patients in routine clinical practice differ from RCT populations with respect to age, comorbidities, and medication. These data are of interest for clinicians and guideline authors and may be relevant for the design of future comparative trials.

Abstract
INTRODUCTION Participants in randomised controlled trials (trials) are generally younger and healthier than many individuals encountered in clinical practice. Consequently, the applicability of trial findings is often uncertain. To address this, results from trials can be calibrated to more representative data sources. In a network meta-analysis, using a novel approach which allows the inclusion of trials whether or not individual-level participant data (IPD) is available, we will calibrate trials for three drug classes (sodium glucose cotransporter 2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP1) receptor analogues and dipeptidyl peptidase-4 (DPP4) inhibitors) to the Scottish diabetes register. METHODS AND ANALYSIS Medline and EMBASE databases, the US clinical trials registry (clinicaltrials.gov) and the Chinese Clinical Trial Registry (chictr.org.cn) will be searched from 1 January 2002. Two independent reviewers will apply eligibility criteria to identify trials for inclusion. Included trials will be phase 3 or 4 trials of SGLT2 inhibitors, GLP1 receptor analogues or DPP4 inhibitors, with placebo or active comparators, in participants with type 2 diabetes, with at least one of glycaemic control, change in body weight or major adverse cardiovascular event as outcomes. Unregistered trials will be excluded.We have identified a target population from the population-based Scottish diabetes register. The chosen cohort comprises people in Scotland with type 2 diabetes who either (1) require further treatment due to poor glycaemic control where any of the three drug classes may be suitable, or (2) who have adequate glycaemic control but are already on one of the three drug classes of interest or insulin. ETHICS AND DISSEMINATION Ethical approval for IPD use was obtained from the University of Glasgow MVLS College Ethics Committee (Project: 200160070). The Scottish diabetes register has approval from the Scottish A Research Ethics Committee (11/AL/0225) and operates with Public Benefit and Privacy Panel for Health and Social Care approval (1617-0147). PROSPERO REGISTRATION NUMBER CRD42020184174.

Abstract
OBJECTIVE Lifestyle intervention is recommended as first-line treatment of diabetes at all ages; however, little is known about the efficacy of lifestyle intervention in older adults with diabetes. We aimed to determine whether lifestyle intervention would improve glycemic control and age-relevant outcomes in older adults with diabetes and comorbidities. RESEARCH DESIGN AND METHODS A total of 100 older adults with diabetes were randomly assigned to 1-year intensive lifestyle intervention (ILI) (diet and exercise at a facility transitioned into community-fitness centers and homes) or healthy lifestyle (HL) group. The primary outcome was change in HbA1c. Secondary outcomes included glucoregulation, body composition, physical function, and quality of life. Changes between groups were analyzed with mixed-model repeated-measures ANCOVA following the intention-to-treat principle. RESULTS HbA1c improved more in the ILI than the HL group (mean ± SE -0.8 ± 0.1 vs. 0.1 ± 0.1%), associated with improved insulin sensitivity (1.2 ± 0.2 vs. -0.4 ± 0.2) and disposition (26.0 ± 8.9 vs. -13.0 ± 8.4 109 min-1) indices (between-group P < 0.001 to 0.04). Body weight and visceral fat decreased more in the ILI than HL group (-8.4 ± 0.6 vs. -0.3 ± 0.6 kg, P < 0.001, and -261 ± 29 vs. -30 ± 27 cm3, P < 0.001, respectively). Physical Performance Test score increased more in the ILI than HL group (2.9 ± 0.6 vs. -0.1 ± 0.4, P < 0.001) as did VO2peak (2.2 ± 0.3 vs. -1.2 ± 0.2 mL/kg/min, P < 0.001). Strength, gait, and 36-Item Short Form Survey (SF-36) Physical Component Summary score also improved more in the ILI group (all P < 0.001). Total insulin dose decreased in the ILI group by 19.8 ± 4.4 units/day. Adverse events included increased episodes of mild hypoglycemia in the ILI group. CONCLUSIONS A lifestyle intervention strategy is highly successful in improving metabolic and functional health of older adults with diabetes.

Abstract
Introduction Patients with chronic obstructive pulmonary disease (COPD) often have poor sleep quality and report a worsening of respiratory symptoms during night-time. However, current clinical guidelines for COPD management do not specifically consider nocturnal symptoms when recommending pharmacological treatment. This study aimed to better understand the burden of nocturnal symptoms in patients with COPD, and to evaluate the importance of nocturnal symptom control compared with daytime and overall symptom control. Methods Data were analyzed from the Adelphi Respiratory Disease Specific Programme, a point-in-time survey of physicians and their patients, conducted in the USA in 2019. Primary care physicians and pulmonologists who managed three or more patients with COPD per month were eligible for inclusion; eligible patients were ≥ 18 years old, with a physician-confirmed diagnosis of COPD. Results Surveys from 171 physicians and 800 patients were analyzed. Everyday symptoms were reported in 14% of patients. In total, 88% of patients reported daytime symptoms, and 74% of patients experienced nocturnal symptoms, with 7% reporting daily nocturnal symptoms. Patients experiencing nocturnal symptoms every day had the greatest impairment in their activity as per the Work Productivity and Activity Impairment questionnaire (mean total activity impairment, 66.9%; nocturnal symptoms once or twice a week, 41.1%; no nocturnal symptoms, 26.4%). Patients experiencing daily nocturnal symptoms also had the lowest quality of life (QoL) as per the EuroQoL 5-Dimension 3-Level score. Physicians reported prescribing therapy based on sustained 24-h symptomatic relief for the majority of patients (78%). They reported nocturnal symptom control as a factor in their choice of therapy for 38% of patients, and daytime symptom control as a reason for 61% of patients. Conclusion Daytime and nocturnal symptoms are common among patients with COPD. Frequency of nocturnal symptoms is related to a significant impairment in activity and health-related QoL.

Abstract
Background Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), affects an estimated 1.6 million US adults, and results in humanistic and economic burden even among mild patients, which grows with increasing disease activity. Methods Gastroenterologists and their IBD patients provided real-world data via US IBD Disease Specific Programmes 2014-2018. Patients with physician- and patient-reported data completing a Work Productivity and Activity Impairment questionnaire were categorized by disease activity, defined using Crohn's Disease Activity Index (CD) and partial Mayo scores (UC), respectively. Associations of disease activity with patient-reported productivity loss and indirect costs were assessed. Results The analyses included 281 patients with CD and 282 patients with UC. Mean ages were 40.0 and 40.5 years, and mean disease durations 7.1 and 5.4 years, for CD and UC, respectively. In CD, absenteeism (0.95%-14.6%), presenteeism (11.7%-44.9%), and overall work impairment (12.4%-51.0%) increased with increasing disease activity (all P < .0001). In UC, absenteeism (0.6%-11.9%), presenteeism (7.1%-37.1%), and overall work impairment (7.5%-41.9%) increased with increasing disease activity (all P < .0001). Annual indirect costs due to total work impairment increased with increasing disease activity (all P < .0001), from $7169/patient/year (remission) to $29 524/patient/year (moderately-to-severely active disease) in CD and $4348/patient/year (remission) to $24 283/patient/year (moderately-to-severely active disease) in UC. Conclusions CD and UC patients experienced increased absenteeism, presenteeism, and overall work impairment with increasing disease activity, resulting in higher indirect costs. Treatments significantly reducing IBD disease activity could provide meaningful improvements in work productivity and associated costs.

Abstract
OBJECTIVE Our objective was to determine the extent to which current evidence from long-term randomised controlled trials (RCTs) of weight management is generalisable and applicable to underserved adult groups with obesity (body mass index (BMI) ≥35 kg/m2). METHODS Descriptive analysis of 131 RCTs, published after 1990-May 2017 with ≥1 year of follow-up, included in a systematic review of long-term weight management interventions for adults with BMI ≥35 kg/m2 (the REBALANCE Project). Studies were identified from MEDLINE, EMBASE, PsychINFO, SCI, CENTRAL and from hand searching. Reporting of trial inclusion and exclusion criteria, trial recruitment strategies, baseline characteristics and outcomes were analysed using a predefined list of characteristics informed by the PROGRESS (Place of residence, Race/ethnicity/culture/language, Occupation, Gender/sex, Religion, Education, Socioeconomic status, Social capital)-Plus framework and the UK Equality Act 2010. RESULTS Few (6.1%) trials reported adapting recruitment to appeal to underserved groups. 10.0% reported culturally adapting their trial materials. Only 6.1% of trials gave any justification for their exclusion criteria, yet over half excluded participation for age or mental health reasons. Just over half (58%) of the trials reported participants' race or ethnicity, and one-fifth reported socioeconomic status. Where outcomes were reported for underserved groups, the most common analysis was by sex (47.3%), followed by race or ethnicity (16.8%). 3.1% of trials reported outcomes according to socioeconomic status. DISCUSSION Although we were limited by poor trial reporting, our results indicate inadequate representation of people most at risk of obesity. Guidance for considering underserved groups may improve the appropriateness of research and inform greater engagement with health and social care services.

Abstract
Type 2 diabetes and its associated comorbidities are growing more prevalent, and the complexity of optimising glycaemic control is increasing, especially on the frontlines of patient care. In many countries, most patients with type 2 diabetes are managed in a primary care setting. However, primary healthcare professionals face the challenge of the growing plethora of available treatment options for managing hyperglycaemia, leading to difficultly in making treatment decisions and contributing to treatment and therapeutic inertia. This position statement offers a simple and patient-centred clinical decision-making model with practical treatment recommendations that can be widely implemented by primary care clinicians worldwide through shared-decision conversations with their patients. It highlights the importance of managing cardiovascular disease and elevated cardiovascular risk in people with type 2 diabetes and aims to provide innovative risk stratification and treatment strategies that connect patients with the most effective care.

Evaluating Diuretics in Normal Care (EVIDENCE): a feasibility report of a pilot cluster randomised trial of prescribing policy in primary care to compare the effectiveness of thiazide-type diuretics in hypertension. Pilot Feasibility Stud 2022; 8:62. [PMID: 35277204 PMCID: PMC8914438 DOI: 10.1186/s40814-022-01016-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Accepted: 02/25/2022] [Indexed: 11/10/2022] Open
Abstract
Background Obtaining evidence on comparative effectiveness and safety of widely prescribed drugs in a timely and cost-effective way is a major challenge for healthcare systems. Here, we describe the feasibility of the Evaluating Diuretics in Normal Care (EVIDENCE) study that compares a thiazide and thiazide-like diuretics for hypertension as an exemplar of a more general framework for efficient generation of such evidence. In 2011, the UK NICE hypertension guideline included a recommendation that thiazide-like diuretics (such as indapamide) be used in preference to thiazide diuretics (such as bendroflumethiazide) for hypertension. There is sparse evidence backing this recommendation, and bendroflumethiazide remains widely used in the UK. Methods Patients prescribed indapamide or bendroflumethiazide regularly for hypertension were identified in participating general practices. Allocation of a prescribing policy favouring one of these drugs was then randomly applied to the practice and, where required to comply with the policy, repeat prescriptions switched by pharmacy staff. Patients were informed of the potential switch by letter and given the opportunity to opt out. Practice adherence to the randomised policy was assessed by measuring the amount of policy drug prescribed as a proportion of total combined indapamide and bendroflumethiazide. Routinely collected hospitalisation and death data in the NHS will be used to compare cardiovascular event rates between the two policies. Results This pilot recruited 30 primary care practices in five Scottish National Health Service (NHS) Boards. Fifteen practices were randomised to indapamide (2682 patients) and 15 to bendroflumethiazide (3437 patients), a study population of 6119 patients. Prior to randomisation, bendroflumethiazide was prescribed to 78% of patients prescribed either of these drugs. Only 1.6% of patients opted out of the proposed medication switch. Conclusion The pilot and subsequent recruitment confirms the methodology is scalable within NHS Scotland for a fully powered larger study; currently, 102 GP practices (> 12,700 patients) are participating in this study. It has the potential to efficiently produce externally valid comparative effectiveness data with minimal disruption to practice staff or patients. Streamlining this pragmatic trial approach has demonstrated the feasibility of a random prescribing policy design framework that can be adapted to other therapeutic areas.

JMIR Res Protoc 2022; 11:e33726.

Abstract
BACKGROUND Hypoglycemia prognostic models contingent on prospective, self-reported survey data offer a powerful avenue for determining real-world event susceptibility and interventional targets. OBJECTIVE This protocol describes the design and implementation of the 1-year iNPHORM (Investigating Novel Predictions of Hypoglycemia Occurrence Using Real-world Models) study, which aims to measure real-world self-reported severe and nonsevere hypoglycemia incidence (daytime and nocturnal) in American adults with type 1 or 2 diabetes mellitus prescribed insulin and/or secretagogues, and develop and internally validate prognostic models for severe, nonsevere daytime, and nonsevere nocturnal hypoglycemia. As a secondary objective, iNPHORM aims to quantify the effects of different antihyperglycemics on hypoglycemia rates. METHODS iNPHORM is a prospective, 12-wave internet-based panel survey that was conducted across the United States. Americans (aged 18-90 years) with self-reported type 1 or 2 diabetes mellitus prescribed insulin and/or secretagogues were conveniently sampled via the web from a pre-existing, closed, probability-based internet panel (sample frame). A sample size of 521 baseline responders was calculated for this study. Prospective data on hypoglycemia and potential prognostic factors were self-assessed across 14 closed, fully automated questionnaires (screening, baseline, and 12 monthly follow-ups) that were piloted using semistructured interviews (n=3) before fielding; no face-to-face contact was required as part of the data collection. Participant responses will be analyzed using multivariable count regression and machine learning techniques to develop and internally validate prognostic models for 1-year severe and 30-day nonsevere daytime and nocturnal hypoglycemia. The causal effects of different antihyperglycemics on hypoglycemia rates will also be investigated. RESULTS Recruitment and data collection occurred between February 2020 and March 2021 (ethics approval was obtained on December 17, 2019). A total of 1694 participants completed the baseline questionnaire, of whom 1206 (71.19%) were followed up for 12 months. Most follow-up waves (10,470/14,472, 72.35%) were completed, translating to a participation rate of 179% relative to our target sample size. Over 70.98% (856/1206) completed wave 12. Analyses of sample characteristics, quality metrics, and hypoglycemia incidence and prognostication are currently underway with published results anticipated by fall 2022. CONCLUSIONS iNPHORM is the first hypoglycemia prognostic study in the United States to leverage prospective, longitudinal self-reports. The results will contribute to improved real-world hypoglycemia risk estimation and potentially safer, more effective clinical diabetes management.

Cardiovascular Profile of Patients with Type 2 Diabetes in France Based on REWIND CVOT Inclusion Criteria: A Real-World Retrospective Study. Diabetes Ther 2022; 13:287-299. [PMID: 35034340 PMCID: PMC8873332 DOI: 10.1007/s13300-021-01200-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 12/24/2021] [Indexed: 11/03/2022] Open
Abstract
INTRODUCTION The REWIND study demonstrated a cardiovascular (CV) benefit of dulaglutide treatment in patients with type 2 diabetes (T2D) with or without established cardiovascular disease (CVD). The current study aims to describe similarities and differences between characteristics of patients with T2D in France and the REWIND population. METHODS A retrospective, observational study was conducted in France using primary care IQVIA electronic medical records. Patients aged ≥ 18 years with at least one clinical visit and/or glucose-lowering agent prescription in 2019 were identified. The percentages of patients aged ≥ 50 years with established CVD, aged ≥ 55 years with subclinical CVD or aged ≥ 60 years with multiple CV risk factors based on REWIND definitions were calculated. RESULTS A total of 63,927 patients with T2D were included. Mean age was 67 years, 93% were aged ≥ 50 years and 58% were male. The median time since T2D diagnosis was 5.6 years, mean glycated hemoglobin was 7.1% and mean body mass index was 30.4 kg/m2. Of the patients included in the current study, 59.4% fulfilled REWIND CV criteria; 12.4% of patients were ≥ 50 years old with established CVD; 9.7% of patients were aged ≥ 55 years with subclinical vascular disease and 44.7% were aged ≥ 60 years with ≥ 2 CV risk factors. CONCLUSION Almost 60% of this primary care French cohort with T2D fulfilled key REWIND CV criteria, with a lower percentage of patients having established CVD than REWIND participants.

Abstract
AIMS In older adults with type 2 diabetes (T2D), overtreatment remains prevalent and undertreatment ignored. The main objective is to estimate the prevalence and examine factors associated with potential overtreatment and undertreatment. METHOD Observational study conducted within an administrative database of older adults with T2D who registered in 2018 at the Portuguese Diabetes Association. Participants were categorized either as potentially overtreated (HbA1c ≤ 7.5%), appropriately on target (HbA1c ≥7.5 to ≤9%), or potentially undertreated (HbA1c > 9%). RESULTS The study included 444 participants: potential overtreatment and undertreatment were found in 60.5% and 12.6% of the study population. Taking the patients on target as a comparator, the group of potentially overtreated showed to be more men (61.3% vs 52.2%), less-obese (34.1% vs 39.2), higher cardiovascular diseases (13.7% vs 11%), peripheral vascular diseases (16.7% vs 12.8%), diabetic foot (10% vs 4.5%), and severe kidney disease (5.2% vs 4.5%). Conversely, the potentially undertreated participants were more women (64.2% vs 47.7%), obese (49% vs 39.2%), had more dyslipidemia (69% vs 63.1%), peripheral vascular disease (14.2% vs 12.8%), diabetic foot (8.9% vs 4.5%), and infections (14.2% vs 11.9%). The odds of potential overtreatment were mostly decreased by 59% of women, 73.5% in those with retinopathy, and 86.3% in insulin, 65.4% sulfonylureas, and 66.8% in SGLT2 inhibitors users. Contrariwise, an increase in the odds of potential undertreatment was more than 4.8 times higher in insulin, and more than 3.1 times higher in sulfonylureas users. CONCLUSION Potential overtreatment and undertreatment in older adults with T2D in routine clinical practice should guide the clinicians to balance the use of newer oral antidiabetic agents considering its safety profile regarding hypoglycemia.

Abstract
Background Research participation is beneficial to patients, clinicians and healthcare services. There is currently poor alignment between UK clinical research activity and local prevalence of disease. The National Institute of Health Research is keen to encourage chief investigators (CIs) to base their research activity in areas of high patient need, to support equity, efficiency and capacity building. We explored how CIs choose sites for their trials and suggest ways to encourage them to recruit from areas with the heaviest burden of disease. Methods Qualitative, semi-structured telephone interviews with a purposive sample of 30 CIs of ongoing or recently completed multi-centre trials, all of which were funded by the UK National Institute of Health Research. Results CIs want to deliver world-class trials to time and budget. Approaching newer, less research-active sites appears risky, potentially compromising trial success. CIs fear that funders may close the trial if recruitment (or retention) is low, with potential damage to their research reputation. We consider what might support a shift in CI behaviour. The availability of ‘heat maps’ showing the disparity between disease prevalence and current research activity will help to inform site selection. Embedded qualitative research during trial set up and early, appropriate patient and public involvement and engagement can provide useful insights for a more nuanced and inclusive approach to recruitment. Public sector funders could request more granularity in recruitment reports and incentivise research activity in areas of greater patient need. Accounts from the few CIs who had ‘broken the mould’ suggest that nurturing new sites can be very successful in terms of efficient recruitment and retention. Conclusion While improvements in equity and capacity building certainly matter to CIs, most are primarily motivated by their commitment to delivering successful trials. Highlighting the benefits to trial delivery is therefore likely to be the best way to encourage CIs to focus their research activity in areas of greatest need.

Abstract
AIM To investigate the external validity of recent antihyperglycaemic trials evaluating cardiovascular outcomes in a multimorbid population. MATERIALS AND METHODS Selection criteria of 15 randomized controlled trials from the 2020 American Diabetes Association Standard of Care statement were applied in a stepwise manner to tertiary care patients with type 2 diabetes. Primary outcomes were the number of patients eligible per individual trial and for the aggregate of trials. Secondary outcomes included patient predictors of trial eligibility. RESULTS Of 1059 patients, the mean (SD) age was 66 (10.74) years, the median (IQR) Charlson index was 2 (2, 3) and 458 (43%) had documented cardiovascular disease. The median (IQR) number of patients included in individual trials was 263 (174.25-308.75) and 795 (75.1%) of them were eligible for at least one trial. Among those 264 ineligible, 127 (48.1%) had an HbA1c level of 7% or less and no cardiovascular disease; 53.5% and 34.4% of the patients were eligible for two and three different classes of drugs, respectively. The strongest predictor of trial eligibility was cardiovascular disease (risk ratio 2.17, 95% CI 2.01-2.35). CONCLUSIONS A considerable proportion of multimorbid patients would be eligible for recent antihyperglycaemic trials. This positive finding can be attributed to development guidance in diabetes trials and the different approach we took, in which we evaluated inclusion by trials as an aggregate.

Abstract
Background Population external validity is the extent to which an experimental study results can be generalized from a specific sample to a defined population. In order to apply the results of a study, we should be able to assess its population external validity. We performed an investigator-initiated randomized controlled trial (RCT) (AIDA study), which compared colistin-meropenem combination therapy to colistin monotherapy in the treatment of patients infected with carbapenem-resistant Gram-negative bacteria. In order to examine the study’s population external validity and to substantiate the use of AIDA study results in clinical practice, we performed a concomitant observational trial. Methods The study was conducted between October 1st, 2013 and January 31st, 2017 (during the RCTs recruitment period) in Greece, Israel and Italy. Patients included in the observational arm of the study have fulfilled clinical and microbiological inclusion criteria but were excluded from the RCT due to receipt of colistin for > 96 h, refusal to participate, or prior inclusion in the RCT. Non-randomized cases were compared to randomized patients. The primary outcome was clinical failure at 14 days of infection onset. Results Analysis included 701 patients. Patients were infected mainly with Acinetobacter baumannii [78.2% (548/701)]. The most common reason for exclusion was refusal to participate [62% (183/295)]. Non-randomized and randomized patients were similar in most of the demographic and background parameters, though randomized patients showed minor differences towards a more severe infection. Combination therapy was less common in non-randomized patients [31.9% (53/166) vs. 51.2% (208/406), p = 0.000]. Randomized patients received longer treatment of colistin [13 days (IQR 10–16) vs. 8.5 days (IQR 0–15), p = 0.000]. Univariate analysis showed that non-randomized patients were more inclined to clinical failure on day 14 from infection onset [82% (242/295) vs. 75.5% (307/406), p = 0.042]. After adjusting for other variables, non-inclusion was not an independent risk factor for clinical failure at day 14. Conclusion The similarity between the observational arm and RCT patients has strengthened our confidence in the population external validity of the AIDA trial. Adding an observational arm to intervention studies can help increase the population external validity and improve implementation of study results in clinical practice. Trial registration The trial was registered with ClinicalTrials.gov, number NCT01732250 on November 22, 2012.

Abstract
Over the last decades, the face of health care has changed dramatically, with big improvements in what is technically feasible. However, there are indicators that the current approach to evaluating evidence in health care is not holistic and hence in the long run, health care will not be sustainable. New conceptual and normative frameworks for the evaluation of health care need to be developed and investigated. The current paper presents a novel framework of justifiable health care and explores how the use of artificial intelligence and big data can contribute to achieving the goals of this framework.

Abstract
Randomized controlled trial (RCT) populations often do not reflect those typically seen in clinical practice. This retrospective, observational cohort study analysed the real-world data of people with type 2 diabetes (T2DM) prescribed basal insulin analogues from electronic medical records (EMRs) in the Explorys database, which includes data from 39 integrated healthcare systems in the United States, to determine how representative selected RCTs investigating insulin glargine 300 U/mL (Gla-300) are of T2DM populations in a real-world setting. Applying eligibility criteria derived from the EDITION 1, 2 and 3 (Gla-300 vs. insulin glargine 100 U/mL [Gla-100]) and BRIGHT (Gla-300 vs. insulin degludec) RCTs, we observed that only 17% (33 345/191 218) of people captured in the real-world database would have been eligible for such trials. Those who were ineligible tended to be older, had more comorbidities and a higher baseline hypoglycaemia rate than the eligible group. Using another large US EMR database (Optum Humedica) as corroboration, we found that 15% (36 285/235 697) would have been eligible to participate in the EDITION/BRIGHT RCTs. Furthermore, only 7% (1734/24 547) would have been eligible for the CONCLUDE (insulin degludec vs. Gla-300) RCT. Our findings remind us of the value of real-world data studies, complementing the results of RCTs, and providing additional insights into groups who would typically be excluded from RCTs.

Abstract
Type 2 diabetes and its associated comorbidities are growing more prevalent, and the complexity of optimising glycaemic control is increasing, especially on the frontlines of patient care. In many countries, most patients with type 2 diabetes are managed in a primary care setting. However, primary healthcare professionals face the challenge of the growing plethora of available treatment options for managing hyperglycaemia, leading to difficultly in making treatment decisions and contributing to therapeutic inertia. This position statement offers a simple and patient-centred clinical decision-making model with practical treatment recommendations that can be widely implemented by primary care clinicians worldwide through shared-decision conversations with their patients. It highlights the importance of managing cardiovascular disease and elevated cardiovascular risk in people with type 2 diabetes and aims to provide innovative risk stratification and treatment strategies that connect patients with the most effective care.

Abstract
BACKGROUND Few studies have addressed external validity of randomized controlled trials in infectious diseases. We aimed to assess the external validity of an investigator-initiated trial on treatment for uncomplicated urinary tract infection. METHODS In the original study, women (n = 513) with urinary tract infection were randomized to nitrofurantoin or fosfomycin treatment in three countries between 2013 and 2017. In the present study we compared women who were screened for enrolment but excluded to women who participated in the trial, both groups in Israel. The primary outcome was the rate of emergency department index visits resulting in hospitalization within 28 days. RESULTS We compared 127 included to 110 excluded patients. The most common reasons for exclusion were logistic difficulties in recruitment and antibiotic use in the preceding month. Included patients tended to be older [39 (IQR 29-59) vs. 35.5 (IQR 24-56.25 years)], more likely to have history of recurrent infection and had more urinary symptoms. Among excluded patients, 13.6% (15/110) had initial visits resulting in hospitalization compared to 3.1% (4/127) of included participants (p = .003). The rate of emergency department visits within 28 days was similar in both groups. Clinical and microbiological failures were significantly more common in included patients [26% (33/127) vs. 1.8% (2/110), p < .001; 7.9% (10/127) vs. 0% (0/110), p = .003; respectively]. CONCLUSIONS While differences were observed between included and excluded patients, the excluded group did not represent a more 'complicated' population. The present study shows the importance of collecting data on patients excluded from randomized controlled trials.

Abstract
BACKGROUND Progressive supranuclear palsy (PSP) is a neurodegenerative disorder with symptoms including vertical gaze palsy, frequent falls, abnormal gait, and cognitive/language/behavioral changes, making diagnosis and treatment challenging. METHODS Descriptive analysis was undertaken of cross-sectional, real-world data for patients with PSP provided by neurologists in France, Germany, Italy, Spain, UK, and USA. RESULTS Data on 892 PSP patients were obtained from patient records. Common initial symptoms included difficulty walking/maintaining gait, confusion/disorientation, loss of balance/falling, and rigidity. These symptoms and vertical gaze palsy commonly aided diagnosis. At data collection, dysphagia and blepharospasm were also very common. Mean times from symptom-onset to consulting a healthcare professional and PSP diagnosis were 5.2 and 15.0 months, respectively. General practitioners or movement disorder specialists were most commonly consulted initially; 98% of patients were diagnosed with PSP by a movement disorder specialist or general neurologist. Alternative diagnoses, including Parkinson's disease (67%) and dementia (10%), were considered for 41% of patients prior to PSP diagnosis. Non-wheelchair walking aids and wheelchairs were used by 60% and 23% of patients, respectively, with mean times from symptom-onset to use being 20.8 and 39.5 months, respectively. Symptomatic medication, most often levodopa and antidepressants, was prescribed for 87% of patients. CONCLUSION This study provided information on disease course and treatment for a large number of PSP patients from various countries. PSP carries a considerable clinical burden. Diagnosis is often delayed. Consulting a movement disorder specialist might expediate diagnosis. Currently, only symptomatic treatments are available with a poor satisfaction, and there is an urgent need for disease-modifying agents.

Abstract
AIMS Although group-level effectiveness of lipid, blood pressure, glucose, and aspirin treatment for prevention of cardiovascular disease (CVD) has been proven by trials, important differences in absolute effectiveness exist between individuals. We aim to develop and validate a prediction tool for individualizing lifelong CVD prevention in people with Type 2 diabetes mellitus (T2DM) predicting life-years gained without myocardial infarction or stroke. METHODS AND RESULTS We developed and validated the Diabetes Lifetime-perspective prediction (DIAL) model, consisting of two complementary competing risk adjusted Cox proportional hazards functions using data from people with T2DM registered in the Swedish National Diabetes Registry (n = 389 366). Competing outcomes were (i) CVD events (vascular mortality, myocardial infarction, or stroke) and (ii) non-vascular mortality. Predictors were age, sex, smoking, systolic blood pressure, body mass index, haemoglobin A1c, estimated glomerular filtration rate, non- high-density lipoprotein cholesterol, albuminuria, T2DM duration, insulin treatment, and history of CVD. External validation was performed using data from the ADVANCE, ACCORD, ASCOT and ALLHAT-LLT-trials, the SMART and EPIC-NL cohorts, and the Scottish diabetes register (total n = 197 785). Predicted and observed CVD-free survival showed good agreement in all validation sets. C-statistics for prediction of CVD were 0.83 (95% confidence interval: 0.83-0.84) and 0.64-0.65 for internal and external validation, respectively. We provide an interactive calculator at www.U-Prevent.com that combines model predictions with relative treatment effects from trials to predict individual benefit from preventive treatment. CONCLUSION Cardiovascular disease-free life expectancy and effects of lifelong prevention in terms of CVD-free life-years gained can be estimated for people with T2DM using readily available clinical characteristics. Predictions of individual-level treatment effects facilitate translation of trial results to individual patients.

Abstract
AIMS To compare the safety and efficacy of insulin glargine 300 U/mL (Gla-300) versus first-generation standard-of-care basal insulin analogues (SOC-BI; insulin glargine 100 U/mL or insulin detemir) at 6 months. METHODS In the 12-month, open-label, multicentre, randomized, pragmatic ACHIEVE Control trial, insulin-naïve adults with type 2 diabetes (T2D) and glycated haemoglobin (HbA1c) 64 to 97 mmol/mol (8.0%-11.0%) after ≥1 year of treatment with ≥2 diabetes medications were randomized to Gla-300 or SOC-BI. The composite primary endpoint, evaluated at 6 months, was the proportion of participants achieving individualized HbA1c targets per Healthcare Effectiveness Data and Information Set (HEDIS) criteria without documented symptomatic (blood glucose ≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia at any time of the day at 6 months. RESULTS Of 1651 and 1653 participants randomized to Gla-300 and SOC-BI, respectively, 31.3% and 27.9% achieved the composite primary endpoint at 6 months (odds ratio [OR] 1.19, 95% confidence interval [CI] 1.01-1.39; P = 0.03 for superiority); 78.4% and 75.3% had no documented symptomatic or severe hypoglycaemia (OR 1.19, 95% CI 1.01-1.41). Changes from baseline to month 6 in HbA1c, fasting plasma glucose, weight, and BI analogue dose were similar between groups. CONCLUSIONS Among insulin-naïve adults with poorly controlled T2D, Gla-300 was associated with a statistically significantly higher proportion of participants achieving individualized HEDIS HbA1c targets without documented symptomatic or severe hypoglycaemia (vs SOC-BI) in a real-life population managed in a usual-care setting. The ACHIEVE Control study results add value to treatment decisions and options for patients, healthcare providers, payers and decision makers.

Abstract
AIM To report the effectiveness and safety of insulin glargine 300 U/mL (Gla-300) versus standard-of-care basal insulin analogues (SOC-BI) at 12 months in the ACHIEVE Control trial, which is a prospective pragmatic randomized real-life study in insulin-naïve adults with type 2 diabetes (T2D). METHODS A total of 3304 insulin-naïve adults with T2D and glycated haemoglobin (HbA1c) concentration of 64 to 97 mmol/mol (8.0% to 11.0%) after ≥1 year of treatment with two or more antihyperglycaemic agents were randomized to Gla-300 or SOC-BI. Key secondary endpoints included HbA1c target attainment without documented symptomatic (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia at 12 months. RESULTS At 12 months, 26.1% (Gla-300) and 23.7% (SOC-BI) of adults achieved HbA1c targets without documented symptomatic (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia (odds ratio [OR] 1.14, 95% confidence interval [CI] 0.97-1.35); 33.0% and 29.5%, respectively, achieved HbA1c targets without documented symptomatic (<3.0 mmol/L [<54 mg/dL]) or severe hypoglycaemia (OR 1.19, 95% CI 1.02-1.38). The OR for HbA1c target achievement was 1.15 (95% CI 0.99-1.34), and favoured Gla-300 versus SOC-BI for absence of documented symptomatic or severe hypoglycaemia at 12 months for both ≤3.9 mmol/L (≤70 mg/dL; OR 1.21, 95% CI 1.05-1.40) and < 3.0 mmol/L (<54 mg/dL; OR 1.26, 95% CI 1.07-1.48). CONCLUSION Gla-300 tended to be associated with lower hypoglycaemia risk than SOC-BI in real-world clinical practice during the 12-month follow-up.

Abstract
Multi-morbidity and polypharmacy are common in older people and pose a challenge for health and social care systems, especially in the context of global population ageing. They are complex and interrelated concepts in the care of older people that require early detection and patient-centred shared decision making underpinned by multi-disciplinary team-led comprehensive geriatric assessment (CGA) across all health and social care settings. Personalised care plans need to remain responsive and adaptable to the needs and wishes of the patient, enabling the individual to maintain their independence. In this review, we aim to give an up-to-date account of the recognition and management of multi-morbidity and polypharmacy in the older person.

Abstract
Primary care physicians are uniquely placed to offer holistic, patient-centred care to patients with T2DM. While the recent FDA-mandated cardiovascular outcome trials offer a wealth of data to inform treatment discussions, they have also contributed to increasing complexity in treatment decisions, and in the guidelines that seek to assist in making these decisions. To assist physicians in avoiding treatment inertia, Primary Care Diabetes Europe has formulated a position statement that summarises our current understanding of the available T2DM treatment options in various patient populations. New data from recent outcomes trials is contextualised and summarised for the primary care physician. This consensus paper also proposes a unique and simple tool to stratify patients into 'very high' and 'high' cardiovascular risk categories and outlines treatment recommendations for patients with atherosclerotic cardiovascular disease, heart failure and chronic kidney disease. Special consideration is given to elderly/frail patients and those with obesity. A visual patient assessment tool is provided, and a comprehensive set of prescribing tips is presented for all available classes of glucose-lowering therapies. This position statement will complement the already available, often specialist-focused, T2DM treatment guidelines and provide greater direction in how the wealth of outcome trial data can be applied to everyday practice.

Abstract
In patients with type 2 diabetes mellitus (T2DM) who require additional glucose-lowering on top of first-line metformin monotherapy, sulfonylureas are the most common choice for second-line therapy followed by dipeptidyl peptidase inhibitors (DPP-4i). This article summarises presentations at a symposium entitled "Real-World Evidence and New Perspectives with Gliclazide MR" held at the International Diabetes Federation Congress in Busan, South Korea on 4 December 2019. Although guideline recommendations vary between countries, the guidelines with the highest quality ratings include sulfonylureas as one of the preferred choices as second-line therapy for T2DM. Data from randomised controlled trials (RCTs) have consistently demonstrated that sulfonylureas are effective glucose-lowering agents and that the risk of severe hypoglycaemia with these agents is low. In addition, both RCTs and real-world observational studies have shown no increased risk of mortality or cardiovascular disease with the use of newer-generation sulfonylureas compared with other classes of glucose-lowering treatments. However, differences between sulfonylureas do exist, with gliclazide being associated with a significantly lower risk of mortality or cardiovascular mortality compared with glibenclamide, as well as the lowest incidence of severe hypoglycaemia compared with other agents in this class. Recent real-world studies into the effectiveness and safety of gliclazide appear to confirm these findings, and publication of new data from these studies in patients with T2DM in the UK, and in Muslim patients who are fasting during Ramadan, are awaited with interest. Another study being undertaken with gliclazide is a pan-India study in patients with maturity-onset diabetes of the young (MODY) subtypes 1, 3 and 12. Patients with these MODY subtypes respond particularly well to sulfonylurea treatment, and sulfonylureas are the first-line agents of choice in these patients. These new and ongoing studies will add to the cumulative data on the efficacy and safety of certain sulfonylureas in patients with diabetes.

Abstract
AIM We examined eligibility and preventable cardiovascular disease events in US adults with diabetes mellitus from the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME). METHODS We identified adults with diabetes mellitus eligible for EMPA-REG OUTCOME based on trial eligibility criteria available from the National Health and Nutrition Examination Surveys, 2007-2016. We estimated composite cardiovascular disease endpoints, as well as all-cause deaths, death from cardiovascular disease and hospitalizations for heart failure from trial treatment and placebo event rates, the difference indicating the preventable events. RESULTS Among 29,629 US adults aged ⩾18 years (representing 231.9 million), 4672 (27.3 million) had diabetes mellitus, with 342 (1.86 million) meeting eligibility criteria of EMPA-REG OUTCOME. We estimated from trial primary endpoint event rates of 10.5% and 12.1% in the empagliflozin and placebo groups, respectively, that based on the 'treatment' of our 1.86 million estimated EMPA-REG OUTCOME eligible subjects, 12,066 (95% confidence interval: 10,352-13,780) cardiovascular disease events could be prevented annually. Estimated annual preventable deaths from any cause, cardiovascular causes and hospitalizations from heart failure were 17,078 (95% confidence interval: 14,652-19,504), 14,479 (95% confidence interval: 12,422-16,536) and 9467 (95% confidence interval: 8122-10,812), respectively. CONCLUSION Empagliflozin, if provided to EMPA-REG OUTCOME eligible US adults, may prevent many cardiovascular disease events, cardiovascular and total deaths, as well as heart failure hospitalizations.

Bower P, Grigoroglou C, Anselmi L, Kontopantelis E, Sutton M, Ashworth M, Evans P, Lock S, Smye S, Abel K. Is health research undertaken where the burden of disease is greatest? Observational study of geographical inequalities in recruitment to research in England 2013-2018. BMC Med 2020; 18:133. [PMID: 32418543 PMCID: PMC7232839 DOI: 10.1186/s12916-020-01555-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Accepted: 03/10/2020] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Research is fundamental to high-quality care, but concerns have been raised about whether health research is conducted in the populations most affected by high disease prevalence. Geographical distribution of research activity is important for many reasons. Recruitment is a major barrier to research delivery, and undertaking recruitment in areas of high prevalence could be more efficient. Regional variability exists in risk factors and outcomes, so research done in healthier populations may not generalise. Much applied health research evaluates interventions, and their impact may vary by context (including geography). Finally, fairness dictates that publically funded research should be accessible to all, so that benefits of participating can be fairly distributed. We explored whether recruitment of patients to health research is aligned with disease prevalence in England. METHODS We measured disease prevalence using the Quality and Outcomes Framework in England (total long-term conditions, mental health and diabetes). We measured research activity using data from the NIHR Clinical Research Network. We presented descriptive data on geographical variation in recruitment rates. We explored associations between the recruitment rate and disease prevalence rate. We calculated the share of patient recruitment that would need to be redistributed to align recruitment with prevalence. We assessed whether associations between recruitment rate and disease prevalence varied between conditions, and over time. RESULTS There was significant geographical variation in recruitment rates. When areas were ranked by disease prevalence, recruitment was not aligned with prevalence, with disproportionately low recruitment in areas with higher prevalence of total long-term and mental health conditions. At the level of 15 local networks, analyses suggested that around 12% of current recruitment activity would need to be redistributed to align with disease prevalence. Overall, alignment showed little change over time, but there was variation in the trends over time in individual conditions. CONCLUSIONS Geographical variations in recruitment do not reflect the suitability of the population for research. Indicators should be developed to assess the fit between research and need, and to allow assessment of interventions among funders, researchers and patients to encourage closer alignment between research activity and burden.

Abstract
Aim: To analyze real-world data relating to treatment decision-making in stage III-IV ovarian cancer (OC). Materials & methods: Real world data were collected from a survey of physicians and their patients (n = 2413) across Europe and the USA in 2017-2018. Results: 49% had stage IVb disease. 39, 54 and 7% of patients received first-line (1L), second-line, or 7% third-line or later treatment. In the 1L (ongoing or completed), 93% received platinum-containing regimens, 26% bevacizumab-containing regimens and 1% a PARP inhibitor-containing regimen. In 1L maintenance treatment, 81% received bevacizumab, 17% platinum-containing treatments and 6% a PARP inhibitor. Conclusion: The most common 1L treatment for advanced ovarian cancer was platinum-containing chemotherapy. Of those receiving 1L maintenance therapy, 70-99% (across countries) received targeted therapy.

Abstract
Background The generalisability of randomized controlled trials (RCTs) can be uncertain because the impact of exclusion criteria is rarely quantified. The aim of this study was to systematically review studies examining the percentage of clinical populations with a physical health condition who would be excluded by RCTs of treatments for that condition. Methods Medline and Embase were searched from inception to Feb 11th 2018. Two reviewers independently completed screening, full-text review, data extraction and risk-of-bias assessment. The primary outcome was the percentage of patients in the clinical population who would have been excluded from each examined trial. Subgroup analyses examined exclusion by population setting, publication date and funding source. Results Titles/abstracts (20,754) were screened, and 50 studies were included which reported exclusion rates from 305 trials of treatments in 31 physical conditions. Estimated rates of exclusion from trials varied from 0% to 100%, and the median exclusion rate was 77.1% of patients (interquartile range 55.5% to 89.0% exclusion). Median exclusion rates for trials in common chronic conditions were high, including hypertension 83.0%, type 2 diabetes 81.7%, chronic obstructive pulmonary disease 84.3%, and asthma 96.0%. The most commonly applied exclusion criteria related to age, co-morbidity and co-prescribing, whereas more implicit criteria relating to life expectancy or functional status were not typically examined. There was no evidence that exclusion varied by the nature of the clinical population in which exclusion was evaluated or trial funding source. There was no statistically significant change in exclusion rates in more recent compared with older trials. Conclusions The majority of trials of treatments for physical conditions examined excluded the majority of patients with the condition being treated. Almost a quarter of the trials studied excluded over 90% of patients, more than half of trials excluded at least three quarters of patients, and four out of five trials excluded at least half of patients. A limitation is that most studies applied only a subset of eligibility criteria, so exclusion rates are likely under-estimated. Exclusion from trials of older people and people with co-morbidity and co-prescribing is increasingly untenable given population aging and increasing multimorbidity.

Effect of diabetes duration on the relationship between glycaemic control and risk of death in older adults with type 2 diabetes. Diabetes Obes Metab 2020; 22:231-242. [PMID: 31596048 DOI: 10.1111/dom.13891] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 09/18/2019] [Accepted: 09/27/2019] [Indexed: 12/16/2022]
Abstract
AIM To investigate the effect of diabetes duration on glycaemic control, measured using mean glycated haemoglobin (HbA1c) level, and mortality risk within different age, sex and clinically relevant, comorbidity-defined subgroups in an elderly population with type 2 diabetes (T2D). METHODS We studied older (≥65 years) primary care patients with T2D, who had three successive annual measurements of HbA1c taken between 2005 and 2013. The primary exposure was the mean of all three HbA1c measurements. Follow-up began on the date of the third measurement. Individual mean HbA1c levels were categorized into clinically relevant groups (<6.5% [<48 mmol/mol]; 6.5%-6.9% [48-52 mmol/mol]; 7%-7.9% [53-63 mmol/mol]; 8%-8.9% [64-74 mmol/mol]; and ≥9% [≥75 mmol/mol]). We used multiple Cox regression to study the effect of glycaemic control on the hazard of all-cause mortality, adjusted for age, sex, use of concomitant medication, and age- and disease-related comorbidities. RESULTS A total of 9734 individuals were included. During a median (interquartile range) follow-up of 7.3 (4.6-8.7) years, 3320 individuals died. We found that the effect of mean HbA1c on all-cause mortality depended on the duration of diabetes (P for interaction <.001). For individuals with short diabetes duration (<5 years), the risk of death increased with poorer glycaemic control (increasing HbA1c), whereas for individuals with longstanding diabetes (≥5 years), we found a J-shaped association, where a mean HbA1c level between 6.5% and 7.9% [48 and 63 mmol/mol] was associated with the lowest risk of death. For individuals with longstanding diabetes, both low (<6.5% [<48 mmol/mol]; hazard ratio [HR] 1.21, 95% confidence interval [CI] 1.07-1.37, P = .002) and high mean HbA1c levels (≥9.0% [≥75 mmol/mol]; HR 1.60, 95% CI 1.28-1.99, P < .001) were associated with an increased risk of death. We also calculated 5-year absolute risks of all-cause mortality, separately for short and long diabetes duration, and found similar risk patterns across different age groups, sex and comorbidity strata. CONCLUSIONS In elderly individuals with T2D, the effect of glycaemic control (measured by HbA1c) on all-cause mortality depended on the duration of diabetes. Of particular clinical importance, we found that strict glycaemic control was associated with an increased risk of death among individuals with long (≥ 5 years) diabetes duration. Conversely, for individuals with short diabetes duration, strict glycaemic control was associated with the lowest risk of death. These results indicate that tight glycemic control may be beneficial in people with short duration of diabetes, whereas a less stringent target may be warranted with longer diabetes exposure.

Representation of people with comorbidity and multimorbidity in clinical trials of novel drug therapies: an individual-level participant data analysis. BMC Med 2019; 17:201.

Abstract
BACKGROUND Clinicians are less likely to prescribe guideline-recommended treatments to people with multimorbidity than to people with a single condition. Doubts as to the applicability of clinical trials of drug treatments (the gold standard for evidence-based medicine) when people have co-existing diseases (comorbidity) may underlie this apparent reluctance. Therefore, for a range of index conditions, we measured the comorbidity among participants in clinical trials of novel drug therapies and compared this to the comorbidity among patients in the community. METHODS Data from industry-sponsored phase 3/4 multicentre trials of novel drug therapies for chronic medical conditions were identified from two repositories: Clinical Study Data Request and the Yale University Open Data Access project. We identified 116 trials (n = 122,969 participants) for 22 index conditions. Community patients were identified from a nationally representative sample of 2.3 million patients in Wales, UK. Twenty-one comorbidities were identified from medication use based on pre-specified definitions. We assessed the prevalence of each comorbidity and the total number of comorbidities (level of multimorbidity), for each trial and in community patients. RESULTS In the trials, the commonest comorbidities in order of declining prevalence were chronic pain, cardiovascular disease, arthritis, affective disorders, acid-related disorders, asthma/COPD and diabetes. These conditions were also common in community-based patients. Mean comorbidity count for trial participants was approximately half that seen in community-based patients. Nonetheless, a substantial proportion of trial participants had a high degree of multimorbidity. For example, in asthma and psoriasis trials, 10-15% of participants had ≥ 3 conditions overall, while in osteoporosis and chronic obstructive pulmonary disease trials 40-60% of participants had ≥ 3 conditions overall. CONCLUSIONS Comorbidity and multimorbidity are less common in trials than in community populations with the same index condition. Comorbidity and multimorbidity are, nevertheless, common in trials. This suggests that standard, industry-funded clinical trials are an underused resource for investigating treatment effects in people with comorbidity and multimorbidity.

How Many Patients with Type 2 Diabetes Meet the Inclusion Criteria of the Cardiovascular Outcome Trials with SGLT2 Inhibitors? Estimations from a Population Database in a Mediterranean Area. J Diabetes Res 2019; 2019:2018374. [PMID: 31815146 PMCID: PMC6877986 DOI: 10.1155/2019/2018374] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Revised: 09/30/2019] [Accepted: 10/16/2019] [Indexed: 12/25/2022] Open
Abstract
OBJECTIVE Regulatory agencies require the assessment of cardiovascular (CV) safety for new type 2 diabetes (T2D) therapies through CV outcome trials (CVOTs). However, patients included in CVOTs assessing sodium-glucose cotransporter-2 inhibitors (SGLT2i) might not be representative of those seen in clinical practice. This study examined the proportion of patients that would have been enrolled into three main SGLT2i CVOTs to determine whether these trials' eligibility criteria can be applied to a real-world Mediterranean T2D population. METHODS Cross-sectional, retrospective, cohort study of T2D patients registered in primary care centres of the Catalan Institute of Health using medical records from a population database (SIDIAP) that includes approximately 74% of the population in Catalonia (Spain). Eligibility criteria were according to those of three SGLT2i CVOTs: EMPA-REG OUTCOME (empagliflozin), CANVAS (canagliflozin), and DECLARE-TIMI 58 (dapagliflozin). RESULTS By the end of 2016, the database included 373,185 patients with T2D with a mean age of 70 ± 12 years, 54.9% male, with a mean duration of T2D of 9 ± 6 years, and a mean glycated haemoglobin (HbA1c) of 7.12% ± 1.32 (59% with HbA1c < 7%). Of these, 86,534 (23%) had established CV disease and 28% chronic renal failure (estimated glomerular filtration < 60 ml/min/1.73m2). Among all included patients, only 8.2% would have qualified for enrolment into the EMPA-REG OUTCOME trial, 29.6% into the CANVAS program, and 38% into the DECLARE-TIMI 58 trial. The main limiting factors for inclusion would have been a previous history of CV disease and the baseline HbA1c value. CONCLUSION The external validity of the analysed CVOTs is clearly limited when applying the same eligibility criteria to a T2D Mediterranean population.

Abstract
AIMS To compare HbA1c and hypoglycaemia in insulin-naïve patients with type 2 diabetes (T2D) who initiated insulin glargine 300 units/mL (Gla-300) or 100 units/mL (Gla-100). MATERIALS AND METHODS This retrospective cohort study examined electronic medical records of insulin-naïve adults with T2D who initiated Gla-300 or Gla-100 during March 2015 through to December 2016 with active records for ≥12 months before and ≥6 months after initiation, and ≥1 valid HbA1c value during 6-month baseline and 90-180-day follow-up. Outcomes included HbA1c and hypoglycaemia. Cohorts were propensity score-matched (1:2) on baseline demographic and clinical characteristics. Sensitivity analyses were conducted using broader inclusion criteria. RESULTS The matched cohorts included 1004 Gla-300 and 2008 Gla-100 initiators (mean age 60.4 years; 53.2% male). During 6-month follow-up, Gla-300 versus Gla-100 initiators had a greater mean HbA1c decrease (-1.52 ± 2.08% vs. -1.30 ± 2.12%; P = 0.003) and more patients achieved HbA1c <7% (25.0% vs. 21.5%; P = 0.029) and <8% (55.0% vs. 49.2%; P = 0.002); and HbA1c <7% (21.9% vs. 17.4%; P = 0.003) and <8% (49.1% vs. 41.8%; P < 0.001) without hypoglycaemia. Gla-300 initiators were similarly or less likely to have any or inpatient/emergency department-associated hypoglycaemia during 3- and 6-month follow-up (e.g. any hypoglycaemia to 6 months: 9.7% vs. 12.5%; adjusted odds ratio 0.61; P = 0.057). CONCLUSIONS Among insulin-naïve adults with T2D, Gla-300 was associated with significantly better HbA1c reductions (latest value during 90-180-day follow-up) and similar or improved hypoglycaemia outcomes (3- and 6-month follow-up) than Gla-100.

Abstract
AIMS To investigate cardiovascular (CV) safety and event rates for dapagliflozin versus other glucose-lowering drugs (GLDs) in a real-world type 2 diabetes population after applying the main inclusion criteria and outcomes from the DECLARE-TIMI 58 study. METHODS Patients with new initiation of dapagliflozin and/or other GLDs were identified in Swedish nationwide healthcare registries for the period 2013 to 2016. Patients were included if they met the main DECLARE-TIMI 58 inclusion criteria: age ≥40 years and established CV disease or presence of multiple-risk factors, e.g. men aged ≥55 years and women aged ≥60 years with hypertension or dyslipidaemia. Propensity scores for the likelihood of dapagliflozin initiation were calculated, then 1:3 matching was carried out. DECLARE-TIMI 58 outcomes were hospitalization for heart failure (HHF) or CV-specific mortality, and major adverse CV events (MACE; CV-specific mortality, myocardial infarction, or stroke). Cox survival models were used to estimate hazard ratios (HRs). RESULTS After matching, a total of 28 408 new-users of dapagliflozin and/or other GLDs were identified, forming the population for the present study (henceforth referred to as the DECLARE-like cohort. The mean age of this cohort was 66 years, and 34% had established CV disease. Dapagliflozin was associated with 21% lower risk of HHF or CV mortality versus other GLDs (HR 0.79, 95% confidence interval [CI] 0.69-0.92) and had no significant association with MACE (HR 0.90, 95% CI 0.79-1.03). HHF and CV mortality risks, separately, were lower at HR 0.79 (95% CI 0.67-0.93) and HR 0.75 (95% CI 0.57-0.97), respectively. Non-significant associations were seen for myocardial infarction and stroke: HR 0.91 (95% CI 0.74-1.11) and HR 1.06 (95% CI 0.87-1.30), respectively. CONCLUSION In a real-world population similar to those included in the DECLARE-TIMI 58 study, dapagliflozin was safe with regard to CV outcomes and resulted in lower event rates of HHF and CV mortality versus other GLDs.

How representative of a general type 2 diabetes population are patients included in cardiovascular outcome trials with SGLT2 inhibitors? A large European observational study. Diabetes Obes Metab 2019; 21:968-974. [PMID: 30537226 PMCID: PMC6590461 DOI: 10.1111/dom.13612] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 12/01/2018] [Accepted: 12/05/2018] [Indexed: 12/28/2022]
Abstract
AIMS Enrollment criteria vary substantially among cardiovascular outcome trials (CVOTs) of sodium-glucose cotransporter-2 inhibitors (SGLT-2is), which impacts the relationship between a trial population and the general type 2 diabetes (T2D) population. The aim of this study was to evaluate the representativeness of four SGLT-2i CVOTs of a general T2D population. METHODS T2D patients from Germany, The Netherlands, Norway and Sweden were included in the study. Given the available data per country, key inclusion and exclusion criteria were defined by diagnoses, procedures and drug treatments to facilitate comparability among countries. Representativeness was determined by dividing the number of patients fulfilling the key enrolment criteria of each CVOT (CANVAS, DECLARE-TIMI 58, EMPA-REG OUTCOME, VERTIS-CV) by the total T2D population. RESULTS In 2015, a total T2D population of 803 836 patients was identified in Germany (n = 239 485), in The Netherlands (n = 36 213), in Norway (n = 149 782) and in Sweden (n = 378 356). These populations showed a 25% to 44% cardiovascular (CV) disease baseline prevalence and high CV-preventive drug use (>80%). The general T2D population had less prevalent CV disease and patients were slightly older than those included in the CVOTs. The DECLARE-TIMI 58 trial had the highest representativeness, 59% compared to the general T2D population, and this representativeness was almost 2-, 3- and 4-fold higher compared to the CANVAS (34%), EMPA-REG OUTCOME (21%) and VERTIS-CV (17%) trials, respectively. CONCLUSIONS In large T2D populations within Europe, consistent patterns of representativeness of CVOTs were found when applying the main enrolment criteria. The DECLARE-TMI 58 trial had the highest representativeness, indicating that it included and examined patients who are most representative of the general T2D patients in the studied countries.

Abstract
Aim: We used Adelphi Real World Disease-Specific Programme data to characterize adults with newly diagnosed or relapsed/refractory de novo acute myeloid leukemia (AML). Materials & methods: Community-practice hematologists/oncologists completed patient record forms for their regular AML patients. Patients were invited to complete patient self-completion forms including 3-Level EuroQol 5-Dimensions (EQ-5D-3L) and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) questionnaires. Results: Physicians provided patient record forms for 389 patients (339 newly diagnosed, 50 relapsed/refractory); 68 patients completed patient self-completion forms. Mean EQ-5D visual-analog scale and index and FACT-General scores were significantly lower than US population norms (p < 0.0001); health-related quality of life (HRQoL) scores were generally lower than 11 other cancers. Conclusion: HRQoL impairment is grave in AML. Efforts are needed to improve HRQoL in affected patients.

Abstract
There is currently a worldwide epidemic of type 2 diabetes (T2D) that is predicted to increase substantially in the next few years. With 80% of the global T2D population living in low to middle-income countries, there are issues with cost and of access to appropriate medicines. The objective of this symposium was to provide an overview of the efficacy and safety of glucose-lowering drugs, focussing in particular on sulfonylureas (SUs) in patients with T2D using data taken from both randomised controlled trials (RCTs) and real-world studies, the application of strategies to ensure optimal patient adherence and clinical outcomes, and the optimal use of SUs in terms of dose adjustment and agent choice to ensure the best clinical outcome. The symposium began by exploring a profile of the typical patient seen in diabetes clinical practice and the appropriate management of such a patient in the real world, before moving on to an overview of the risks associated with T2D and how the currently available agents, including newer antidiabetic medications, mitigate or exacerbate those risks. The final presentation provided an overview of real-world studies, the gap between RCTs and the real world, and the use of available glucose-lowering agents in daily clinical practice. Clinical evidence was presented demonstrating that tight glucose control improved both microvascular and macrovascular outcomes, but that aggressive treatment in patients with a very high cardiovascular risk could lead to adverse outcomes. Real-world data suggest that older agents such as SUs and metformin are being used in a large proportion of patients with T2D with demonstrable effectiveness, indicating that they still have a place in modern T2D management. The symposium, while acknowledging the need for newer antidiabetic drugs in specific situations and patient groups, recommended the continuation of SUs and metformin as the primary oral antidiabetic agents in resource-constrained regions of the world.Funding:Servier.

Abstract
Most of the clinical research conducted with the goal of improving health is not generalizable to nonresearch settings. In addition, scientists often fail to replicate each other's findings due, in part, to lack of attention to contextual factors accounting for their relative effectiveness or failure. To address these problems, we review the literature on assessment of external validity and summarize approaches to designing for generalizability. When investigators conduct systematic reviews, a critical need is often unmet: to evaluate the pragmatism and context of interventions, as well as their effectiveness. Researchers, editors, and grant reviewers can implement key changes in how they consider and report on external validity issues. For example, the recently published expanded CONSORT figure may aid scientists and potential program adopters in summarizing participation in and representativeness of a program across different settings, staff, and patients. Greater attention to external validity is needed to increase reporting transparency, improve program dissemination, and reduce failures to replicate research.

Diabetes Obes Metab 2018; 20:2148-2158. [PMID: 29938887 PMCID: PMC6099352 DOI: 10.1111/dom.13345] [Citation(s) in RCA: 52] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Revised: 04/19/2018] [Accepted: 05/01/2018] [Indexed: 12/18/2022]
Abstract
AIMS To compare clinical outcomes in patients with type 2 diabetes (T2D) switching from insulin glargine 100 units/mL (Gla-100) or insulin detemir (IDet) to insulin glargine 300 units/mL (Gla-300) or insulin degludec (IDeg). MATERIALS AND METHODS We conducted a retrospective, observational study of electronic medical records for Gla-300/IDeg adult switchers (March 1, 2015 to January 31, 2017) with active records for 12-month baseline (glycated haemoglobin [HbA1c] used a 6-month baseline period) and 6-month follow-up periods. Gla-300 and IDeg switchers were propensity score-matched using baseline demographic and clinical characteristics. Outcomes were HbA1c change and goal attainment (among patients with HbA1c captured at follow-up), and hypoglycaemia with fixed follow-up (intention-to-treat [ITT]; 6 months) and variable follow-up (on-treatment [OT]; to discontinuation or 6 months). RESULTS Each matched cohort comprised 1592 patients. The mean decrease in HbA1c and HbA1c goal (<7.0% [53 mmol/mol] and <8.0% [64 mmol/mol]) attainment rates were similar for Gla-300 (n = 742) and IDeg (n = 727) switchers. Using fixed follow-up (ITT method), hypoglycaemia incidence decreased significantly from baseline with Gla-300 (all hypoglycaemia: 15.6% to 12.7%; P = .006; hypoglycaemia associated with inpatient/emergency department [ED] encounter: 5.3% to 3.5%; P = .007), but not with IDeg. After adjusting for baseline hypoglycaemia, no significant differences in hypoglycaemia incidence and event rate were found at follow-up (ITT) for Gla-300 vs IDeg. Using variable follow-up (OT), hypoglycaemia incidence was similar in both groups, but Gla-300 switchers had a lower inpatient/ED hypoglycaemia event rate at follow-up (adjusted rate ratio 0.56; P = .016). CONCLUSIONS In a real-world setting, switching from Gla-100 or IDet to Gla-300 or IDeg was associated with similar improvements in glycaemic control and hypoglycaemia in adult patients with T2D.
