Chronic Medication Burden and Complexity for US Patients with Type 2 Diabetes Treated with Glucose-Lowering Agents.

ABSTRACT:

Introduction

Most adults with type 2 diabetes (T2D) have several chronic conditions treated with complex regimens and multiple medications. The burden and complexity of multiple medication use are associated with worse patient outcomes, including reduced adherence and increased costs, hospitalizations, mortality rates, and HbA1c. This study quantifies the chronic medication burden, regimen complexity, and potential medication interactions in patients with T2D using a nationwide claims database in the USA.

Methods

Adults with T2D treated for greater than half of the year with at least one glucose-lowering agent (GLA) in 2017 were included in this descriptive study. Chronic medications were defined as all GLAs and non-GLA medications prescribed for at least 90 days in 2017 to at least 2% of the cohort. Medication burden, defined as the number of medications prescribed, was examined. Medication complexity, proxied by the Medication Regimen Complexity Index (MRCI), and potential use of interacting medications were also examined. Results were investigated for all chronic medications and were reported on the basis of the disease treated (diabetes or other condition) and the route of administration (oral or other).

Results

On average, in 2017, the 814,156 patients included in the study filled prescriptions for 4.1 chronic medications (standard deviation [SD]?=?2.0), 3.7 oral chronic medications (SD?=?1.9), 1.5 GLAs (SD?=?0.8), and 1.1 oral GLAs (SD?=?0.7). The average MRCI was 14.7 for all chronic medications (SD?=?7.4), with a mean of 12.4 for all oral chronic medications (SD?=?6.3), 6.6 for all GLAs (SD?=?3.8), and 4.9 for oral GLAs (SD?=?2.6).

Conclusion

On average, patients with T2D used multiple medications, had a complex medication regimen, and were at potential risk of medication interactions. These findings suggest that patients, practitioners, pharmacists, and payers may benefit from interventions which decrease medication burden, complexity, and/or adverse events related to the treatment of T2D.

Project description:Epidemiologic studies have shown a relationship between glycated hemoglobin levels and cardiovascular events in patients with type 2 diabetes. We investigated whether intensive therapy to target normal glycated hemoglobin levels would reduce cardiovascular events in patients with type 2 diabetes who had either established cardiovascular disease or additional cardiovascular risk factors.In this randomized study, 10,251 patients (mean age, 62.2 years) with a median glycated hemoglobin level of 8.1% were assigned to receive intensive therapy (targeting a glycated hemoglobin level below 6.0%) or standard therapy (targeting a level from 7.0 to 7.9%). Of these patients, 38% were women, and 35% had had a previous cardiovascular event. The primary outcome was a composite of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes. The finding of higher mortality in the intensive-therapy group led to a discontinuation of intensive therapy after a mean of 3.5 years of follow-up.At 1 year, stable median glycated hemoglobin levels of 6.4% and 7.5% were achieved in the intensive-therapy group and the standard-therapy group, respectively. During follow-up, the primary outcome occurred in 352 patients in the intensive-therapy group, as compared with 371 in the standard-therapy group (hazard ratio, 0.90; 95% confidence interval [CI], 0.78 to 1.04; P=0.16). At the same time, 257 patients in the intensive-therapy group died, as compared with 203 patients in the standard-therapy group (hazard ratio, 1.22; 95% CI, 1.01 to 1.46; P=0.04). Hypoglycemia requiring assistance and weight gain of more than 10 kg were more frequent in the intensive-therapy group (P<0.001).As compared with standard therapy, the use of intensive therapy to target normal glycated hemoglobin levels for 3.5 years increased mortality and did not significantly reduce major cardiovascular events. These findings identify a previously unrecognized harm of intensive glucose lowering in high-risk patients with type 2 diabetes. (ClinicalTrials.gov number, NCT00000620.)

Project description:IntroductionResearch has shown that glycemic control is associated with lower rates of microvascular and long-term cardiovascular complications. In the analyses reported here, we examined treatment failure on oral glucose-lowering agents (GLAs), defined as having sustained hemoglobin A1c (HbA1c) ≥ 7%.MethodsThis study utilized the IBM® MarketScan® Claims and Laboratory Data from 1 January 2012 through 30 June 2018. Adults with type 2 diabetes (T2D) were classified based upon the maximum number of classes of GLAs prescribed per day during the time period from 1 July 2012 through 31 December 2012. Patients were followed for 5.5 years in order to examine time to failure on oral GLAs, defined based upon receipt of ≥ 2 consecutive HbA1c results ≥ 7%. Multivariable analyses employing a Cox proportional hazards model were used to examine time to failure overall and based upon the number of index classes of oral GLAs prescribed. For patients who had sustained HbA1c above the threshold, multivariable analyses examined the duration of time that HbA1c remained above the threshold (i.e, glycemic burden) and whether or not an additional oral or injectable class of GLA was added to the patient treatment regimen (i.e., clinical inertia).ResultsA total of 4156 patients were included in the study, of whom 16% were identified with sustained HbA1c ≥ 7% after 365 days (1 year) and 36% after 730 days (2 years), with half of all patients having sustained HbA1c above target after 1102 days (3 years). There was a statistically significant difference in time to having sustained HbA1c above target based upon index classes of therapy, with patients treated with more GLAs being quicker to have HbA1c above target (P < 0.0001). Among those patients who were found to have sustained HbA1c ≥ 7%, the average number of days in the post-period that HbA1c remained above target was 1026 (2.8 years). Only 36% of patients with sustained HbA1c above target added a GLA to their treatment regimen and, for patients who did add such a therapy, the average duration from identification of HbA1c above target until treatment intensification was 401 days (1.1 years). Multivariable analyses revealed that, among those with sustained HbA1c ≥ 7%, treatment with more classes of oral GLAs was associated with a significantly higher glycemic burden and significantly lower odds of clinical inertia.ConclusionThese results indicate that for many patients treated with oral GLAs, glycemic control is not consistently achieved. For patients with above-target HbA1c , the results indicate a relatively large glycemic burden and clinical inertia towards treatment intensification. The findings illustrate some limitations associated with treatment of T2D with oral GLAs.

Project description:BackgroundSodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of a deterioration in heart failure (HF) and mortality in patients with a broad range of cardiovascular risks. Recent guidelines recommend considering the use of SGLT2 inhibitors in patients with type 2 diabetes (T2D) and HF, irrespective of their glycemic control status and background use of other glucose-lowering agents including metformin. However, only a small number of studies have investigated whether the effects of SGLT2 inhibitor in these patients differ by the concomitant use of other glucose-lowering agents.MethodsThis was a post-hoc analysis of the CANDLE trial (UMIN000017669), an investigator-initiated, multicenter, open-label, randomized, controlled trial. The primary aim of the analysis was to assess the effect of 24 weeks of treatment with canagliflozin, relative to glimepiride, on N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration in patients with T2D and clinically stable chronic HF. In the present analysis, the effect of canagliflozin on NT-proBNP concentration was assessed in the patients according to their baseline use of other glucose-lowering agents.ResultsAlmost all patients in the CANDLE trial presented as clinically stable (New York Heart Association class I to II), with about 70% of participants having HF with a preserved ejection fraction phenotype (defined as a left ventricular ejection fraction ≥ 50%) at baseline. Of the 233 patients randomized to either canagliflozin (100 mg daily) or glimepiride (starting dose 0.5 mg daily), 85 (36.5%) had not been taking any glucose-lowering agents at baseline (naïve). Of the 148 patients who had been taking at least one glucose-lowering agent at baseline (non-naïve), 44 (29.7%) and 127 (85.8%) had received metformin or a dipeptidyl dipeptidase-4 (DPP-4) inhibitor, respectively. The group ratio (canagliflozin vs. glimepiride) of proportional changes in the geometric means of NT-proBNP concentration was 0.95 (95% confidence interval [CI] 0.76 to 1.18, p = 0.618) for the naïve subgroup, 0.92 (95% CI 0.79 to1.07, p = 0.288) for the non-naïve subgroup, 0.90 (95% CI 0.68 to 1.20, p = 0.473) for the metformin-user subgroup, and 0.91 (95% CI 0.77 to 1.08, p = 0.271) for the DPP-4 inhibitor-user subgroup. No heterogeneity in the effect of canagliflozin, relative to glimepiride, on NT-proBNP concentration was observed in the non-naïve subgroups compared to that in the naïve subgroup.ConclusionThe impact of canagliflozin treatment on NT-proBNP concentration appears to be independent of the background use of diabetes therapy in the patient population examined.

Project description:IntroductionThe efficacy and safety of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, were investigated in patients with type 2 diabetes (T2D) in the Peptide InnOvatioN for Early diabEtes tReatment (PIONEER) programme. The current post-hoc exploratory subgroup analyses evaluated outcomes by background medication and insulin regimen subgroups.MethodsData from patients in the PIONEER 3-5, 7 and 8 trials receiving once-daily oral semaglutide (14 mg/flexibly dosed) or a comparator (placebo, sitagliptin 100 mg or liraglutide 1.8 mg) were analysed for efficacy (glycated haemoglobin [HbA1c] and body weight changes from baseline to planned end of treatment) and safety outcomes. Patients were grouped according to background medication (metformin, sulphonylurea, thiazolidinedione, sodium-glucose cotransporter-2 inhibitor, insulin, or combinations thereof). Efficacy outcomes were analysed using the trial product estimand (which assumes that patients remained on the trial product without rescue medication use). A separate analysis by background insulin regimen (basal, premixed or basal-bolus) was done for PIONEER 8 using the treatment policy estimand (regardless of trial product discontinuation or rescue medication use). Safety outcomes were analysed descriptively for all patients.ResultsIn total, 2836 patients receiving oral semaglutide 14 mg/flexibly dosed or comparators were included. Baseline characteristics were generally similar across background medication subgroups within each trial. Diabetes duration tended to be longer in patients receiving more background medications. Greater HbA1c and body weight reductions were seen across background medication subgroups with oral semaglutide (changes from baseline: - 1.0 to - 1.5% and - 2.2 to - 5.0 kg, respectively) than with comparators (except for similar HbA1c reductions vs liraglutide). There were no statistically significant interactions by treatment and background medication subgroup for change in HbA1c or body weight except for change in HbA1c (background insulin vs insulin plus metformin) in PIONEER 8 (p = 0.0408). Changes in HbA1c and body weight were generally similar across insulin regimen subgroups, without significant treatment interactions by subgroup, and the total daily insulin dose was decreased for patients receiving oral semaglutide. The incidence of adverse events was generally similar in background medication subgroups.ConclusionOral semaglutide was effective at lowering HbA1c and body weight, regardless of background medications, and appears suitable for a broad range of patients with T2D in combination with other glucose-lowering agents.Trial registrationClinicaltrials.gov: NCT02607865 (PIONEER 3), NCT02863419 (PIONEER 4), NCT02827708 (PIONEER 5), NCT02849080 (PIONEER 7) and NCT03021187 (PIONEER 8).
