[PMID: 38861137 PMCID: PMC11263532 DOI: 10.1007/s13300-024-01588-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Accepted: 04/11/2024] [Indexed: 06/12/2024] Open
Abstract
INTRODUCTION In this phase 4, multicentre, prospective, non-interventional PIONEER REAL Netherlands study, we assessed clinical outcomes associated with once-daily oral semaglutide use in real-world clinical practice in adults living with type 2 diabetes (T2D) naïve to injectable glucose-lowering medication. METHODS Participants initiated on oral semaglutide were followed for 34-44 weeks. Change in glycated haemoglobin (HbA1c) from baseline (BL) to end of study (EOS) was the primary endpoint; secondary endpoints included change in body weight (BW) from BL to EOS, the proportion of participants with HbA1c < 7.0% at EOS and the composite endpoints of HbA1c reduction ≥ 1.0%-points with BW reduction ≥ 3% or ≥ 5% at EOS. Treatment satisfaction was assessed using the Diabetes Treatment Satisfaction Questionnaire (DTSQ status/change). Safety was evaluated in all participants who initiated oral semaglutide treatment. RESULTS Oral semaglutide was initiated in 187 participants; 94.1% completed the study and 78.6% remained on treatment at EOS. At BL, 54.0% of participants were male, mean age was 58.8 years, mean duration of T2D was 8.7 years and mean body mass index was 35.1 kg/m2; mean HbA1c was 8.6% and mean BW was 103.1 kg. Significant improvements from BL to EOS were observed for HbA1c and BW (estimated change [95% confidence interval]: - 1.16%-points [- 1.48 to - 0.85]; p < 0.0001, and - 5.84 kg [- 6.88 to - 4.80]; p < 0.0001, respectively). At EOS, 47.5% of participants had an HbA1c level < 7.0%; 41.8% and 35.5% of participants achieved composite endpoints of HbA1c reduction ≥ 1.0%-points plus BW reduction ≥ 3% or ≥ 5%, respectively. DTSQ status and change scores improved by 2.1 (p = 0.0003) and 10.8 points (p < 0.0001), respectively. Oral semaglutide was easy or very easy to consume for 81.5% of participants. Adverse events were mostly mild/moderate, with gastrointestinal disorders being the most common. CONCLUSION In this real-world population, we reported clinically significant reductions in HbA1c and BW, improved treatment satisfaction and no new safety concerns.

Deriving Treatment Decision Support From Dutch Electronic Health Records by Exploring the Applicability of a Precision Cohort-Based Procedure for Patients With Type 2 Diabetes Mellitus: Precision Cohort Study. Online J Public Health Inform 2024; 16:e51092. [PMID: 38691393 PMCID: PMC11097050 DOI: 10.2196/51092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 02/28/2024] [Accepted: 03/15/2024] [Indexed: 05/03/2024] Open
Abstract
BACKGROUND The rapidly increasing availability of medical data in electronic health records (EHRs) may contribute to the concept of learning health systems, allowing for better personalized care. Type 2 diabetes mellitus was chosen as the use case in this study. OBJECTIVE This study aims to explore the applicability of a recently developed patient similarity-based analytics approach based on EHRs as a candidate data analytical decision support tool. METHODS A previously published precision cohort analytics workflow was adapted for the Dutch primary care setting using EHR data from the Nivel Primary Care Database. The workflow consisted of extracting patient data from the Nivel Primary Care Database to retrospectively generate decision points for treatment change, training a similarity model, generating a precision cohort of the most similar patients, and analyzing treatment options. This analysis showed the treatment options that led to a better outcome for the precision cohort in terms of clinical readouts for glycemic control. RESULTS Data from 11,490 registered patients diagnosed with type 2 diabetes mellitus were extracted from the database. Treatment-specific filter cohorts of patient groups were generated, and the effect of past treatment choices in these cohorts was assessed separately for glycated hemoglobin and fasting glucose as clinical outcome variables. Precision cohorts were generated for several individual patients from the filter cohorts. Treatment options and outcome analyses were technically well feasible but in general had a lack of statistical power to demonstrate statistical significance for treatment options with better outcomes. CONCLUSIONS The precision cohort analytics workflow was successfully adapted for the Dutch primary care setting, proving its potential for use as a learning health system component. Although the approach proved technically well feasible, data size limitations need to be overcome before application for clinical decision support becomes realistically possible.

The real-world observational prospective study of health outcomes with dulaglutide and liraglutide in type 2 diabetes patients (TROPHIES): resource use and costs of treatment in clinical practice in France, Germany, and Italy. J Med Econ 2024; 27:866-879. [PMID: 38963346 DOI: 10.1080/13696998.2024.2367919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 06/11/2024] [Indexed: 07/05/2024]
Abstract
AIMS To describe healthcare resource utilization (HCRU) and associated costs after initiation of injectable glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy by adult patients with type 2 diabetes (T2D) in the prospective, observational, 24-month TROPHIES study in France, Germany, and Italy. MATERIALS AND METHODS HCRU data for cost calculations were collected by treating physicians during patient interviews at baseline and follow-up visits approximately 6, 12, 18, and 24 months after GLP-1 RA initiation with once-weekly dulaglutide or once-daily liraglutide. Costs were evaluated from the national healthcare system (third-party payer) perspective and updated to 2018 prices. RESULTS In total, 2,005 patients were eligible for the HCRU analysis (1,014 dulaglutide; 991 liraglutide). Baseline patient characteristics were generally similar between treatment groups and countries. The largest proportions of patients using ≥2 oral glucose-lowering medications (GLMs) at baseline (42.9-43.4%) and month 24 (44.0-45.1%) and using another injectable GLM at month 24 (15.3-23.2%) were in France. Mean numbers of primary and secondary healthcare contacts during each assessment period were highest in France (range = 4.0-10.7) and Germany (range = 2.9-5.7), respectively. The greatest proportions (≥60%) of mean annualized costs per patient comprised medication costs. Mean annualized HCRU costs per patient varied by treatment cohort and country: the highest levels were in the liraglutide cohort in France (€909) and the dulaglutide cohort in Germany (€883). LIMITATIONS Limitations included exclusion of patients using insulin at GLP-1 RA initiation and collection of HCRU data by physician, not via patient-completed diaries. CONCLUSIONS Real-world HCRU and costs associated with the treatment of adults with T2D with two GLP-1 RAs in TROPHIES emphasize the need to avoid generalization with respect to HCRU and costs associated with a particular therapy when estimating the impact of a new treatment in a country-specific setting.

Abstract
AIM To investigate initial and subsequent treatments prescribed to newly diagnosed type 2 diabetes mellitus (T2DM) patients. METHODS Data from SIDIAP (Information System for Research in Primary Care) including all recorded incident T2DM patients in primary care between 2015 and 2020. We used descriptive statistics and different graphical techniques to describe the most frequent longitudinal patterns. RESULTS A total of 86,854 patients were included. 78.3% of the patients began treatment with a single metformin medication and 21.7% began with a combination therapy (CT). Metformin was the most frequent treatment as first and third-line therapy, while the CT of metformin with DPP4i or sulfonylurea was more prevalent as second-line. Most common first to third-line pattern was initial metformin for 15 months, adding a second antidiabetic in the second line, staying in CT for 6 months, and switching back to single metformin. Treatment patterns varied depending on HbA1c levels, with higher levels (>8%) being associated with changes to CT and lower levels with switches to monotherapy or temporary discontinuation. CONCLUSION The study described in detail the different treatment patterns in incident T2DM patients in Catalonia, its adherence to the guidelines, and how the changes are associated to the HbA1c dynamics.

Abstract
The aim of the study was to assess the initiation of insulin therapy in patients with type 2 diabetes using health claims data on prescription medicines. The study evaluated time to insulin initiation and prescribing patterns of other anti-diabetic medicines before and after insulin initiation. Five years after starting non-insulin antidiabetic therapy, 6.4 % of patients were prescribed insulin, which is substantially lower compared to other similar studies. Among all patients who initiated insulin therapy in 2013, 30 % did not continue any other antidiabetic therapy. However, this proportion was lowered to 20 % in 2018. Before insulin initiation in 2018, metformin was prescribed in only 67 % of patients and sulfonylureas in 78 % of patients. Moreover, metformin and sulfonylureas were discontinued after insulin initiation in 26 and 37 % of patients, resp. More attention should be paid to the continuation of oral anti-diabetics, particularly metformin, after insulin initiation.

Abstract
Type 2 diabetes (T2D) rates in children and adolescents are rising globally. T2D is a complex and aggressive disease in children with several comorbidities, high treatment failure rates, and insulin needs within a few years from diagnosis. While myriads of pharmacotherapies are licensed to treat adults with T2D, treatments accessible to children and adolescents have been limited until recently. Metformin is an old drug with multiple beneficial metabolic health effects beyond glycemic control. This review discusses Metformin's origins, its mechanisms of action, and evidence for its use in the pediatric population to treat and prevent T2D. We also explore the evidence for its use as an obesity therapy, which is the primary driver of T2D, and T2D-driven comorbidities. While emerging therapies create new horizons for managing pediatric T2D, Metformin remains an inexpensive and safe part of the treatment plans of many T2D children globally for its beneficial metabolic effects.

Abstract
The scientific landscape of treatments for type 2 diabetes (T2D) has changed rapidly in the last decade with newer treatments becoming available. However, a large proportion of people with T2D are not able to achieve glycaemic goals because of clinical inertia. The majority of T2D management is in primary care, where clinicians (medical, nursing and pharmacist staff) play an important role in addressing patient needs and achieving treatment goals. However, management of T2D is challenging because of the heterogeneity of T2D and complexity of comorbidity, time constraints, guidance overload and the evolving treatments. Additionally, the current coronavirus disease pandemic poses additional challenges to the management of chronic diseases such as T2D, including routine access to patients for monitoring and communication. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are a class of agents that have evolved rapidly in recent years. These agents act in a glucose-dependent manner to promote insulin secretion and inhibit glucagon secretion, as well as enhancing satiety and reducing hunger. As a result, they are effective treatment options for people with T2D, achieving glycated haemoglobin reductions, weight loss and potential cardiovascular benefit, as monotherapy or as add-on to other glucose-lowering therapies. However, given the complexity of managing T2D, it is important to equip primary care clinicians with clear information regarding efficacy, safety and appropriate positioning of GLP-1 RA therapies in clinical practice. This review provides a summary of clinical and real-world evidence along with practical guidance, with the aim of aiding primary care clinicians in the initiation and monitoring of GLP-1 RAs to help ensure that desired outcomes are realised. Furthermore, a benefit/risk tool has been developed on the basis of current available evidence and guidelines to support primary care clinicians in selecting individuals who are most likely to benefit from GLP-1 RA therapies, in addition to indicating clinical situations where caution is needed.

Abstract
AIM When glycaemic control for people with type 2 diabetes is not achieved with metformin and sulfonylurea alone, adding another oral anti-diabetes drug, such as a sodium-glucose co-transporter 2 (SGLT2) or dipeptidyl peptidase-4 (DPP-4) inhibitor, is an alternative to starting insulin. The aim of this study is to determine the cost-effectiveness of dapagliflozin (an SGLT2 inhibitor) compared with DPP-4 inhibitors when added to metformin and sulfonylurea in people with type 2 diabetes in the Netherlands. METHODS A cost-utility analysis is performed using the Cardiff diabetes model, a fixed-time increment stochastic simulation model informed by 'United Kingdom Prospective Diabetes Study 68' risk equations. The base-case analysis uses a 40-year time horizon, a Dutch societal perspective and differential discounting (4% for costs, 1.5% for effects). Inputs are obtained from the literature and Dutch price lists. Univariate and probabilistic sensitivity analysis are performed. RESULTS Dapagliflozin is dominant compared with DPP-4 inhibitors, resulting in a €990 cost saving and a 0.28 quality-adjusted life year gain over 40 years. Cost savings are associated mainly with treatment costs and a reduced incidence of micro- and macrovascular complications, among others nephropathy, myocardial infarction and stroke. Results are robust to changes in input parameters. CONCLUSIONS Dapagliflozin is a cost-saving alternative to DPP-4 inhibitors when added to metformin and sulfonylurea. The incidence of micro- and macrovascular complications is lower for people treated with dapagliflozin. Uncertainty around this outcome is low.

Abstract
Background: Chronic obstructive pulmonary disease (COPD) is often accompanied by
psychiatric problems, such as depression and anxiety, affecting both
treatment outcomes and mortality. Evidence for the number of COPD patients
using medication for these disorders is sparse. In this study, chronic
antidepressant (ATD) and anxiolytic (ANX) drug use – to identify depression
and anxiety – among COPD patients was compared with subjects with or without
other chronic diseases. Methods: The NControl database containing prescription data of 800 pharmacies
including 7 million individuals in The Netherlands was used. Patients of age
55+ years who received frequent prescriptions – at least two/year in 5 out
of 6 years – for COPD medication, dermatological drugs, disease-modifying
antirheumatic drugs (DMARDs), statins and oral glucose-lowering medication
were analyzed for concomitant chronic use of ATDs and ANXs between 1 January
2013 and 1 January 2019. All other subjects aged 55+ years were included as
a control group (control group 1). This group was further stratified into a
group of subjects that received frequent prescriptions of any kind (control
group 2). Results: 15.2% of the patients that receive COPD treatment
(n = 96,319), 15.3% of subjects that are treated for
dermatological problems (n = 62,865), 13.2% of subjects
that receive DMARDs (n = 7900), 11.6% of statins users
(n = 422,376) and 11.4% of oral glucose-lowering
medication users (n = 165,975) are also chronically treated
for depression or anxiety, compared with 2.6% (control group 1;
n = 3,290,608) and 11.4% (control group 2;
n = 757,947). In general, female and 75+ years aged
subjects showed a higher risk for using ATDs and ANXs chronically. In the
COPD and the dermatological patient group the risk was the highest compared
with the other patient groups. Conclusions: The rates of chronic ATD and ANX use and the risk of having depression and/or
anxiety are especially high in COPD patients, indicating that psychiatric
problems are more common in COPD than in most other chronic diseases. In
general, age and gender strongly influence the risk of chronically using
ATDs and ANXs. The reviews of this paper are available via the supplemental
material section.

Abstract
Objective To determine antiemetic prescription fill patterns during pregnancy in Norway, with special focus on the use of ondansetron and recurrent use in subsequent pregnancies. Methods We conducted a population-based registry study based on data from the Medical Birth Registry of Norway linked to the Norwegian Prescription Database for 762,437 pregnancies >12 gestational weeks ending in live or non-live births between 2005 and 2017. Prescription fills of medications used for nausea and vomiting of pregnancy were summarized in treatment pathways to determine drug utilization patterns. Logistic regression analyses were used to estimate associations between maternal and pregnancy characteristics and antiemetic prescription fills. Results The prescription fill rate for antiemetic medication during pregnancy was 7.6%. However, prescription fill rates were 35.5% in the second pregnancy after filling an antiemetic prescription in the first pregnancy and 53.5% for women who filled antiemetic prescriptions in the previous 2 pregnancies. Among pregnancies with antiemetic prescription fills, 62.2% were dispensed metoclopramide, 28.2% meclizine, and 17.2% promethazine. First-line treatment started with monotherapy in 97.4% of these pregnancies, which was the only treatment received in 78.7%. Prescriptions for ondansetron were filled in 0.3% of pregnancies, with 76.9% being initially filled in the first trimester. Ondansetron as first-line prescription medication and/or use in the first trimester was associated with proxies for more severe nausea and vomiting of pregnancy, including a diagnosis of hyperemesis gravidarum, multiple gestations, a higher obstetric comorbidity index, and concomitant use of medication for gastroesophageal reflux disease and nervous system medications. Women who filled an antiemetic prescription in their first pregnancy were less likely to have subsequent pregnancies than women who did not fill an antiemetic prescription in their first pregnancy (OR 0.93, 95% CI 0.90–0.96). Conclusion Complex patterns of antiemetic prescription fills in pregnancy may mirror the challenge of optimal management of nausea and vomiting of pregnancy in clinical practice, especially for women with severe symptoms.
