Long-term effect of apomorphine infusion in advanced Parkinson\u2019s disease: a real-life study

Long-term effects of continuous subcutaneous apomorphine infusion (CSAI) on health-related quality of life (HRQoL) and predictors of CSAI discontinuation are poorly known. Data from consecutive advanced Parkinson’s disease patients treated in routine care were retrospectively collected over 24 months after CSAI initiation, with a focus on the 39-item Parkinson’s disease questionnaire (PDQ-39). We determined predictors of CSAI discontinuation and HRQoL improvement using multiple regression analysis. Of the 110 subjects evaluated over a 2-year period, 35% discontinued CSAI. Of those who continued treatment, HRQoL remained stable with a sustained reduction in motor fluctuations. The observed effect on dyskinesias was mild and transient. Of note, patients with preexisting impulse control disorders showed an overall good tolerability. PDQ-39 was the only baseline predictor of HRQoL improvement after 2 years of treatment. The presence of dyskinesias, poorer psychological status, shorter disease duration, male sex, and worse OFF state were predictors of discontinuation. Best candidates for CSAI are patients with: (i) poor baseline HRQoL and (ii) marked motor fluctuations.

PMH54 Impact of Bipolar Disorder Treatment Discontinuation on Healthcare Utilization and Costs in the Real-World Setting

To describe the real-world antipsychotic (AP) treatment discontinuation patterns and the association between treatment discontinuation and healthcare costs among bipolar disorder patients. A retrospective observational study was conducted using administrative claims data the IBM® MarketScan Commercial Database. Patients with at least 1 medical claim with a diagnosis of bipolar disorder (manic or mixed sub-type) and newly initiating AP therapy between 1/1/11-6/30/16 were included. Baseline patient characteristics were assessed in the 12 months prior to the AP initiation. Total healthcare costs and healthcare utilization were assessed during a 24-month follow-up. Discontinuation of index AP therapy, defined as a gap of at least 60 days without the medication on-hand, was utilized as a predictor of healthcare costs and utilization outcomes in generalized linear and logistic regression models adjusted for baseline characteristics. Predictors of discontinuation were also assessed via logistic regression. A total of 18,259 bipolar disorder patients were identified as new initiators of APs. The cohort was 61% female and had an average age of 39 years. The most commonly initiated AP was quetiapine (33.6%), followed by aripiprazole (29.3%). A total of 15,460 patients (85%) discontinued their index regimen. Patients with baseline substance use disorders, depression, and other anxiety disorders were significantly more likely to discontinue. More than half of the cohort utilized emergency room services (53%) and 33% had at least one inpatient admission during the follow-up. The median total healthcare costs were $24,861 during the 24-month follow-up. Controlling for differences in baseline characteristics, discontinuation of AP therapy was associated with 24% higher total healthcare costs (Cost ratio: 1.24; p<0.001) and 33% higher inpatient+ER costs (1.33; p<0.001). Discontinuation of AP therapy among bipolar disorder patients is high and contributes to excess healthcare costs and high-cost services. Future research focusing on the reasons for discontinuation may inform medication adherence initiatives.

Multicenter Study of Secukinumab Survival and Safety in Spondyloarthritis and Psoriatic Arthritis: SEcukinumab in Cantabria and ASTURias Study.

Objectives: We aimed to evaluate the drug retention rate and safety of secukinumab (SEC) in patients with axial spondyloarthritis (AxSpA) and psoriatic arthritis (PsA) in a real clinical setting.Methods: This multicenter retrospective observational study included all AxSpA and PsA patients who received at least one dose of SEC. Adverse events (AE) and the drug retention rate were the main study outcomes. Drug survival was analyzed by Kaplan-Meier curves while predictive factors of discontinuation were evaluated using a Cox regression analysis. The weight of these associations was estimated by hazard ratio (HR) values.Results: We included 154 patients (59 PsA and 95 AxSpA). Mean disease duration was 6.5 years (IQR 2-8). Sixty-one percent of patients were treated with two or more biologics prior to SEC. The 1 and 2-year retention rates for SEC were 66 and 43%, respectively. The main causes of discontinuation were inefficacy (59%) and AE (36%). The factors associated with lower risk of discontinuation were male gender (HR 0.54, 95% CI 0.38-0.78 p = 0.001), obesity (HR 0.53, 95% CI 0.30-0.93 p = 0.027), hypertension (HR 0.55, 95% CI 0.30-0.93 p = 0.008), and diabetes (HR 0.42 95% CI 0.18-0.99 p = 0.047) while number of previous biologics and depression were predictors of discontinuation (HR 1.18, 95% CI 1.04-1.34 p = 0.011 and HR 2.53, 95% CI 1.61-3.96 p < 0.001).Conclusions: SEC showed a good retention rate in a population previously exposed to several biological therapies. As a novelty, cardiometabolic comorbidities were associated with better drug survival.

Predictors of discontinuation and hospitalization during long-acting injectable antipsychotic treatment in patients with schizophrenia spectrum disorder.

The aim of this study was to evaluate discontinuation and hospitalization rates in patients with schizophrenia spectrum disorder who were treated with long-acting injectable (LAI) antipsychotics. We recorded clinical data about the period before the LAI treatment, when LAI treatment was initiated, and during the LAI treatment. Variables related to early (<8 weeks) and other LAI discontinuations and hospitalization were analyzed. Out of 452 patients, 14.4% of them discontinued their LAI treatment before 8 weeks, another 24.8% of the patients stopped their LAI by themselves later. Early discontinuers were younger, had shorter duration of illness, and less educated. Sixty-two (27.2%) of the patients were hospitalized under LAI treatment and 40% of the hospitalizations occurred in initial 6 months. Rate of hospitalization was 36.1% in the group who discontinued LAI after 8 weeks. In logistic regression analysis, younger age, history of combined antipsychotic treatment, number of hospitalizations before LAI, use of LAI for less than 6 months and alcohol abuse under LAI treatment were found related to hospitalization. Our findings suggested that discontinuation and hospitalization are still common among the patients who were treated with LAI antipsychotics.

Treatment persistence in patients with type 2 diabetes treated with glucagon‐like peptide‐1 receptor agonists in clinical practice in Sweden

AimTo compare treatment persistence in patients with type 2 diabetes initiating the glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) dulaglutide, exenatide once‐weekly (QW), liraglutide or lixisenatide in routine clinical practice in Sweden and assess clinical outcomes.Materials and MethodsWe performed a retrospective study using data from several nationwide Swedish health registries, including the National Diabetes Register and other mandatory and population‐based registries. Individual level data were collected from 17 361 patients who initiated GLP‐1 RA treatment from 23 May 2015 to 15 October 2017, up to 2.5 years postindex (treatment start date). Treatment persistence and modification, predictors of discontinuation, HbA1c and body weight were recorded. Non‐persistence was defined as a treatment gap of more than 45 days. Treatment modification included switching and augmentation. Confounding was addressed through the use of propensity scores.ResultsTreatment persistence was higher and treatment modifications were lower in patients initiating dulaglutide compared with those on exenatide QW, liraglutide and lixisenatide. Patients who remained on the same treatment for 1‐year postindex experienced greater HbA1c reductions and a steadier decrease in body weight.ConclusionsOur study suggests that in clinical practice in Sweden there is a greater persistence of treatment among patients initiating dulaglutide compared with those on exenatide QW, liraglutide and lixisenatide. Persistence with the index GLP‐1 RA was closely correlated with positive clinical outcomes and thus should be considered a critical factor of patient‐centric treatment in Sweden.

Why patients stop using their home telehealth technologies over time: Predictors of discontinuation in Veterans with heart failure

BackgroundDaily use of home telehealth (HT) technologies decreases over time. Barriers to continued use are unclear. PurposeTo examine predictors of drop-out from HT in Veterans with heart failure. MethodsData for Veterans with heart failure enrolled in the Veterans Affairs HT Program were analyzed using a mixed effects Cox regression model to determine risk of dropping-out over a 1-year period. FindingsOlder (hazard ratio [HR] 1.01), sicker (prior hospital readmission [HR 1.39]), higher probability of hospital admission/death [HR 1.23], functional impairments [1.14]) and white Veterans (compared to black; HR 1.41) had higher risk of drop-out in HT Programs. Users of VA's online patient portal (HR 0.90) had lower risk of drop-out. DiscussionOlder and sicker patients are at most risk of stopping HT use, yet use of a patient portal shows promise in improving continued use. Interventions targeting patients at high risk for HT discontinuation are needed to promote ongoing engagement.

Discontinuation of Statins in Veterans Admitted to Nursing Homes near the End of Life.

Geriatric guidelines recommend against statin use in older adults with limited life expectancy (LLE) or advanced dementia (AD). This study examined resident and facility factors predicting statin discontinuation after nursing home (NH) admission in veterans with LLE/AD taking statins for secondary prevention. Retrospective cohort study of Veterans Affairs (VA) bar code medication administration records, Minimum Data Set (MDS) assessments, and utilization records linked to Medicare claims. VA NHs, known as community living centers (CLCs). Veterans aged 65 and older with coronary artery disease, stroke, or diabetes mellitus, type II, admitted in fiscal years 2009 to 2015, who met criteria for LLE/AD on their admission MDS and received statins in the week after admission (n = 13,110). Residents were followed until statin discontinuation (ie, gap in statin use ≥14 days), death, or censoring due to discharge, day 91 of the stay, or end of the study period. Competing risk models assessed cumulative incidence and predictors of discontinuation, stratified by whether the resident had their end-of-life (EOL) status designated or used hospice at admission. Overall cumulative incidence of statin discontinuation was 31% (95% confidence interval [CI] = 30%-32%) by day 91, and it was markedly higher in those with (52%; 95% CI = 50%-55%) vs without (25%; 95% CI = 24%-26%) EOL designation/hospice. In patients with EOL designation/hospice (n = 2,374), obesity, congestive heart failure, and admission from nonhospital settings predicted decreased likelihood of discontinuation; AD, dependency in activities of daily living, greater number of medications, and geographic region predicted increased likelihood of discontinuation. In patients without EOL designation/hospice (n = 10,736), older age and several specific markers of poor prognosis predicted greater discontinuation, whereas obesity/overweight predicted decreased discontinuation. Most veterans with LLE/AD taking statins for secondary prevention do not discontinue statins following CLC admission. Designating residents as EOL status, hospice use, and individual clinical factors indicating poor prognosis may prompt deprescribing.

Exenatide Once Weekly: Effectiveness, Tolerability, and Discontinuation Predictors in a Real-world Setting

PurposeThe goal of this study was to evaluate the effectiveness and safety of exenatide once weekly (EOW) and to determine predictors of treatment response and drug discontinuation in patients with type 2 diabetes mellitus (T2DM) followed up for 18 months in a real-world setting. MethodsThis retrospective cohort study included patients with T2DM who initiated EOW 2 mg between 2014 and 2019 in an outpatient diabetes clinic in Italy. Data were collected at baseline and at follow-up visits (6, 12, and 18 months after EOW). We estimated glycosylated hemoglobin (HbA1c) and body weight mean changes from baseline to follow-up visits and assessed the proportion of patients reaching HbA1c target ≤7% and a 5% weight loss after 12 months of treatment. We then attempted to establish predictors of glycemic and weight response, and compared patient characteristics between subjects who persisted on treatment versus those who discontinued EOW. FindingsOne-hundred eighty-six patients (46.2% male) were included in the study. The mean (SD) age and diabetes duration were 63.2 (8.9) years and 10.7 years (18.3), respectively. Significant reductions in HbA1c values (−0.9%; 95% CI, −1.1 to −0.8) and body weight (−2.8 kg; 95% CI, −3.4 to −2.2) were observed after 6 months. Sixty-one percent of patients (87 of 143) achieved target HbA1c values ≤ 7% after 12 months, and 34% (45 of 134) exhibited a weight loss of at least 5% of baseline body weight. Blood glucose and weight reductions were maintained after an 18-month follow-up. Predictors of adequate glycemic and weight response were shorter diabetes duration and nonuse of a different GLP-1RA, respectively. Patients on sulfonylureas failed to reach metabolic and body weight targets. The most common adverse events were gastrointestinal side effects (7.5%) and injection site reactions (6.4%), followed by headache (1.1%) and allergic reactions (1.1%). Forty-three percent of patients (79 of 186) discontinued EOW. The main reasons for discontinuation were insufficient HbA1c improvement and/or limited weight reduction (19.9%), side effects (16.1%), or patient decision (6.5%). Predictors of discontinuation were higher HbA1c levels at baseline and use of basal insulin therapy before EOW treatment. ImplicationsEOW treatment, in a real-world setting, offers sustained and effective glycemic control and weight loss over 18 months in patients with T2DM. Diabetes duration and basal insulin therapy, however, may affect the outcome of EOW treatment, suggesting that early initiation of EOW could improve glycemic control and reduce the risk of treatment discontinuation.

Discontinuation rates of warfarin versus direct acting oral anticoagulants in US clinical practice: Results from Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II (ORBIT-AF II)

The ORBIT-AF II Registry enrolled 10,005 total AF patients with a CHA2DS2VASc score of ≥2 on warfarin or DOACs from 235 clinical practices across the US from February 13, 2013 and July 12, 2017. Descriptive statistics and multivariable Cox regression modeling were used to describe baseline characteristics and predictors of discontinuation. Unadjusted and adjusted discontinuation rates and 95% confidence intervals (CI) were calculated using Cox proportional hazards models and propensity score adjustment, respectively. At baseline, 16.4% (N = 1642/10,005) were treated with warfarin, 83.6% (N = 8363/10,005) with DOACs and 1498/10,005 patients (15.0%) discontinued therapy [warfarin = 236/1642 (14.4%) vs DOACs = 1262/8363 (15.1%)]. At 6 and 12 months respectively, among 7049 patients with a new diagnosis of AF within 6 months, adjusted discontinuation rates for warfarin versus DOACs were as follows: [6 months: 7.9%, 95%CI (6.8%-9.0%) vs 9.6% (8.4%-10.7%), P = .16]; [12 months: 12.7% (11.0%-14.3%) vs 15.3% (13.6%-16.9%), P = .02)]. Patients who discontinued therapy with warfarin or DOACs had higher risk of adverse clinical outcomes including: all-cause mortality and cardiovascular death (CV) than those who continued treatment. In a community based AF cohort, adjusted rates of discontinuation at 12-months were higher in DOAC-treated versus VKA-treated patients. Discontinuation of oral anticoagulation was associated with increased absolute risk of all-cause mortality and CV death. URL:https://clinicaltrials.gov. Unique Identifier: NCT01701817.

Abatacept in rheumatoid arthritis: survival on drug, clinical outcomes, and their predictors\u2014data from a large national quality register

BackgroundThere are limited data regarding efficacy of abatacept treatment for rheumatoid arthritis (RA) outside clinical trials. Quality registers have been useful for observational studies on tumor necrosis factor inhibition in clinical practice. The aim of this study was to investigate clinical efficacy and tolerability of abatacept in RA, using a national register.MethodsRA patients that started abatacept between 2006 and 2017 and were included in the Swedish Rheumatology Quality register (N = 2716) were investigated. Survival on drug was estimated using Kaplan-Meier analysis. The European League Against Rheumatism (EULAR) good response and Health Assessment Questionnaire (HAQ) response (improvement of ≥ 0.3) rates (LUNDEX corrected for drug survival) at 6 and at 12 months were assessed. Predictors of discontinuation were investigated by Cox regression analyses, and predictors of clinical response by logistic regression. Significance-based backward stepwise selection of variables was used for the final multivariate models.ResultsThere was a significant difference in drug survival by previous biologic disease-modifying antirheumatic drug (bDMARD) exposure (p < 0.001), with longer survival in bionaïve patients. Men (hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.74–0.98) and methotrexate users (HR 0.85, 95% CI 0.76–0.95) were less likely to discontinue abatacept, whereas a high pain score predicted discontinuation (HR 1.14 per standard deviation, 95% CI 1.07–1.20). The absence of previous bDMARD exposure, male sex, and a low HAQ score were independently associated with LUNDEX-corrected EULAR good response. The absence of previous bDMARD exposure also predicted LUNDEX-corrected HAQ response.ConclusionsIn this population-based study of RA, bDMARD naïve patients and male patients were more likely to remain on abatacept with a major clinical response.

Switching Biologics in the Treatment of Psoriasis: A Multicenter Experience

Background/Objective: The purpose of our study was to provide evidence on the treatment choices, reasons, and results of switching between biologic agents in treating patients with psoriasis. Methods: We conducted a retrospective database search of six tertiary referral centers for pso­riasis patients between January 2007 and May 2019. We analyzed patient and treatment characteristics of all patients in the registry. Results: We enrolled 427 psoriatic patients treated with biologics, and 145 (34%) required a switch to another biologic. The reasons for discontinuing the first biologic agent were inefficacy (n = 106, 62.4%), adverse events (n = 28, 16.5%), and others (n = 36, 21.2%). At week 12, there was a 67.7% reduction in the Psoriasis Area and Severity Index (PASI) score of patients treated with their first biologic, and 51.4% reduction for the second. A drug survival analysis showed no statistically significant difference between the drug survival of first-line biologic agents, but ustekinumab had the highest survival rate among second-line biologics (log-rank p = 0.010). Multivariate analyses for overall drug discontinuation showed that the occurrence of psoriatic arthritis (OR: 1.883, 95% CI: 1.274–2.782, p = 0.001), nail involvement (OR: 2.334, 95% CI: 1.534–3.552, p < 0.001), and use of concomitant treatment (OR: 2.303, 95% CI: 1.403 –3.780, p = 0.001) are predictors for discontinuation. Conclusion: Discontinuation of treatment was most commonly due to inefficacy. Patients who switched to a different biologic agent showed a similar improvement in PASI scores compared to biologic-naive patients. Switching to a second biologic therapy due to inefficacy or adverse events caused by the first one may improve psoriasis.

Relapse rates following antipsychotic discontinuation in the maintenance phase after first-episode of schizophrenia: Results of a long-term follow-up study

BackgroundWhen the antipsychotic treatment should be discontinued after first-episode of schizophrenia (FES) in patients who had a good response to initial treatment is still controversial. The aim of this naturalistic follow-up study was to determine the rate of antipsychotic discontinuation in the maintenance phase and its consequences, after FES. MethodsFES patients (n = 105) were followed-up for at least 24 months and up to 22 years (mean = 99.1 months). After minimum one-year antipsychotic treatment without relapse, some patients’ antipsychotics were discontinued by psychiatrist. We compared the clinical characteristics of this group to those who stopped their medication themselves and analyzed the predictors of being relapse-free after discontinuation. ResultsSeventeen (16.2%) of the patients’ antipsychotic was discontinued by their psychiatrist. Using the same antipsychotic during the first year was the predictor of discontinuation by the psychiatrist in logistic regression analysis. Ten (58.8%) of them relapsed. Thirty-nine patients (37.1%) discontinued their antipsychotic themselves, relapse rate was 76.9% (n = 30). There was no clinical difference between these two groups. Overall, the patients who had no relapse after discontinuation had better role and global functioning at baseline, were more likely to meet remission criteria, and their antipsychotic was discontinued by psychiatrist and use same antipsychotic during the first year. ConclusionOur findings suggest that antipsychotic discontinuation by psychiatrist was possible for only small portion of the FES patients, and relapse rates are high after discontinuation even in these selected patients.

Statin treatment after acute coronary syndrome: Adherence and reasons for non-adherence in a randomized controlled intervention trial

Studies of secondary prevention for cardiovascular disease show low fulfilment of guideline-recommended targets. This study explored whether nurse-led follow-up could increase adherence to statins over time and reasons for discontinuation. All patients admitted for acute coronary syndrome at Östersund hospital between 2010–2014 were screened for the randomized controlled NAILED-ACS trial. The trial comprises two groups, one with nurse-led annual follow-up and medical titration by telephone to reach set intervention targets and one with usual care. All discontinuations of statins were recorded prospectively for at least 36 months and categorized as avoidable or unavoidable. Kaplan-Meier estimates were conducted for first and permanent discontinuations. Predictors for discontinuation were analysed using multivariate Cox regression, statin type and mean LDL-C at end of follow-up. Female gender was a predictor for discontinuation. Allocation in the intervention group predicted increased risk for a first but decreased risk for permanent discontinuation. A nurse-led telemedical secondary prevention programme in a relatively unselected ACS cohort leads to increased adherence to statins over time, greater percentage on potent treatment and lower LDL-C compared to usual care. An initially increased tendency toward early discontinuation in the intervention group stresses the importance of a longer duration of structured follow-up.

Statins in Older Danes: Factors Associated With Discontinuation Over the First 4 Years of Use.

Use of statins is considerable among older persons. We investigated factors associated with statin discontinuation in new statin users aged 70 years or older within the first 4 years of use. Register-based descriptive drug utilization study using data from 2008 to 2016. All Danish persons, aged 70 years or older, initiating statin treatment. Rates and predictors of statin discontinuation after 1 year (early), 2 years, and 4 years. Predictors of discontinuation were estimated using logistic regression. We included 83 788 statin initiators. At 1 year, 13% had discontinued their treatment, while another 12% and 13% discontinued after 2 and 4 years, respectively. The overall discontinuation rate over 4 years was 32%. Increasing age was associated with discontinuation at all time points (adjusted odds ratio [OR] = 2.06 [95% confidence interval {CI} = 1.35-3.16] at 1 year, adjusted OR = 3.94 [95% CI, 1.83-8.49] at 4 years, comparing those aged >95 years to those aged 70-74 years). Further, higher comorbidity scores and use of more than 10 medications were modestly associated with discontinuation. Use of statins for secondary prevention was associated with decreased odds of discontinuation compared to primary prevention at 1 year (adjusted OR = 0.74; 95% CI, 0.65-0.83) and at 4 years (adjusted OR = 0.83; 95% CI, 0.72-0.95), along with concomitant use of cardiovascular (CV) therapies. The annual proportion of early discontinuers ranged from 14% to 17% for primary prevention and from 9% to 12% for secondary prevention between 2008 and 2015. Statin discontinuation within the first 4 years after initiation appeared to be influenced most strongly by age, and may also be influenced by comorbidity, polypharmacy, use for secondary prevention, and concomitant CV medication use. Future research should clarify reasons for, and discussions about, statin discontinuation and initiation among older persons, to provide additional insight on this topic.

Persistence rates of abatacept and TNF inhibitors used as first or second biologic DMARDs in the treatment of rheumatoid arthritis: 9\xa0years of experience from the Rhumadata\xae clinical database and registry

BackgroundTreatment persistence is an important consideration when selecting a therapy for chronic conditions such as rheumatoid arthritis (RA). We assessed the long-term persistence of abatacept or a tumor necrosis factor inhibitor (TNFi) following (1) inadequate response to a conventional synthetic disease-modifying antirheumatic drug (first-line biologic agent) and (2) inadequate response to a first biologic DMARD (second-line biologic agent).MethodsData were extracted from the Rhumadata® registry for patients with RA prescribed either abatacept or a TNFi (adalimumab, certolizumab, etanercept, golimumab, or infliximab) who met the study selection criteria. The primary outcome was persistence to abatacept and TNFi treatment, as first- or second-line biologics. Secondary outcomes included the proportion of patients discontinuing therapy, reasons for discontinuation, and predictors of discontinuation. Persistence was defined as the time from initiation to discontinuation of biologic therapy. Baseline characteristics were compared using descriptive statistics; cumulative persistence rates were estimated using Kaplan-Meier methods, compared using the log-rank test. Multivariate Cox proportional hazard models were used to compare the persistence between treatments, controlling for baseline covariates.ResultsOverall, 705 patients met the selection criteria for first-line biologic agent initiation (abatacept, n = 92; TNFi, n = 613) and 317 patients met the criteria for second-line biologic agent initiation (abatacept, n = 105; TNFi, n = 212). There were no clinically significant differences in baseline characteristics between the treatments with either first- or second-line biologics. Persistence was similar between the first-line biologic treatments (p = 0.7406) but significantly higher for abatacept compared with TNFi as a second-line biologic (p = 0.0001). Mean (SD) times on first-line biologic abatacept and TNFi use were 4.53 (0.41) and 5.35 (0.20) years, and 4.80 (0.45) and 2.82 (0.24) years, respectively, as second-line biologic agents. The proportion of patients discontinuing abatacept and TNFi in first-line was 51.1% vs. 59.5% (p = 0.1404), respectively. In second-line, it was 57.1% vs. 74.1% (p = 0.0031). The main reasons for stopping both treatments were inefficacy and adverse events.ConclusionsAbatacept and TNFi use demonstrated similar persistence rates at 9 years as a first-line biologic agent. As a second-line biologic agent, abatacept had better persistence rates over a TNFi.

Uptake and use of a diabetes management program with a mobile glucometer

ObjectiveInnovative mobile health technologies (mHealth) may facilitate self-management of blood glucose. This study evaluates uptake, use, and predictors of uptake and long-term use of a diabetes mHealth intervention, which comprises an FDA-approved mobile glucometer and nurse coaching, in a real-world setting. Methodsn = 4438 commercially-insured adults with diabetes were recruited from 2014 to 2015 via an opt-in, phone-based process. In this post-only study, we obtained data on recruitment, glucometer use, demographics, and insurance and employer characteristics. We calculated percent uptake and reasons for unsuccessful recruitment. We used logistic regression to model predictors of uptake and survival analysis to examine duration of testing and predictors of discontinuation. ResultsOf the recruited members, 556 (12.5%) signed up for the mHealth program and 324 (7.3%) began testing. Of those who did not sign up, the majority (70.6%) were unable to be reached by phone. Male (OR = 1.60, 95% CI: 1.25, 2.03) and Spanish-speaking (OR = 8.34, 95% CI: 5.40, 12.88) members were more likely to start testing. Two-thirds (66.2%) of those who started testing had a first test value that indicated hyperglycemia; 97% tested more than once and the median time between first and last test was 407 days. Older age was the only significant predictor of long-term use. ConclusionsAlthough uptake of the mHealth program was low, most members who started testing had initial glucose values that indicated a need for better glucose management and the majority of patients engaged with the program for over a year. Male and Spanish-speaking members were more likely to initiate the program.

Changes in Oral Anticoagulation Therapy over One Year in 51,000 Atrial Fibrillation Patients at Risk for Stroke: A Practice-Derived Study.

This study assessed changes in anticoagulation therapy over time in patients with atrial fibrillation (AF). Analyses were performed on a claims-based dataset of 4 million health-insured individuals. The study population consisted of patients newly initiating a non-vitamin-K oral anticoagulants (NOACs) or vitamin K antagonist (VKA) for AF between 2013 and 2016. The study outcomes consisted of the proportion of patients who had (1) discontinued OAC treatment, (2) switched from VKA to NOAC, (3) switched from NOAC to VKA or (4) switched from one NOAC to another. Predictors of discontinuation or switching of OAC treatment were determined by Cox proportional hazards regression models with time-independent and time-dependent covariates. The study population comprised 51,606 AF patients initiating VKA (n = 21,468, 41.6%), apixaban (n = 8,832, 17.1%), dabigatran (n = 3,973, 7.7%) or rivaroxaban (n = 17,333, 33.6%). After 1 year, 29.9% of VKA and 29.5% of NOAC patients had discontinued OAC treatment without switching to another anticoagulant. A total of 10.7% of VKA patients switched to NOACs within 1 year, whereas 4.9% NOAC patients had switched to VKA. Of AF patients who were initiated on a NOAC, 5.2% switched to another NOAC. Treatment changes among NOAC starters were strongly associated with occurrence of stroke, myocardial infarction and gastrointestinal bleeding after treatment initiation. For VKA starters switching to a NOAC, stroke and bleeding events were associated with an increased likelihood of switching. Overall discontinuation rates of VKA and NOACs are comparable over the first year of therapy, while switching from VKA to NOAC was more common than from NOAC to VKA. The majority of treatment changes were associated with clinical events.

Real-world Pattern of Biologic Use in Patients With Inflammatory Bowel Disease: Treatment Persistence, Switching, and Importance of Concurrent Immunosuppressive Therapy.

Medication persistence, defined as the time from drug initiation to discontinuation of therapy, has been suggested as a proxy for real-world therapeutic benefit and safety. This study seeks to compare the persistence of biologic drugs among patients with inflammatory bowel disease (IBD). Patients with newly diagnosed IBD were included in a retrospective study using Truven MarketScan database. Treatment persistence and switching was compared among biologic medications including infliximab, adalimumab, certolizumab, golimumab, and vedolizumab. Predictors for discontinuation and switching were evaluated using time-dependent proportional hazard regression. In total, 5612 patients with Crohn's disease (CD) and 3533 patients with ulcerative colitis (UC) were included in this analysis. Less than half of the patients continued using their initial biologic treatment after 1 year (48.48% in CD cohort; 44.78% in UC cohort). In the first year, adalimumab had the highest persistence and lowest switching rates for both CD (median survival time: 1.04 years) and UC (median survival time: 0.84 years). In subsequent years, infliximab users were more likely to persist in the use of biologic. Combination therapy with immunomodulators significantly decreased the risk of discontinuation, especially when immunomodulator therapy was started more than 30 days before the biologic (hazard ratio [HR], 0.22; CI, 0.16, 0.32). The major predictors for noncompliance included infection and hospitalization. Overall, the persistence profiles of biologics suggest a high rate of dissatisfaction or adverse disease outcomes resulting in discontinuation and switching to a different agent. Early initiation of immunomodulators will substantially increase the persistence of biologic treatment.

Retention Rate, Persistence and Safety of Adalimumab in Inflammatory Bowel Disease: A Real-Life, 9-Year, Single-Center Experience in Italy

"Real-life" data of retention rate and persistence of adalimumab in inflammatory bowel disease are still limited. To analyze retention rate, persistence, and safety of adalimumab in a 9-year real-life cohort of inflammatory bowel disease patients. In this observational, retrospective single-center study, all adult patients treated with adalimumab as the first- and second-line biological treatment for steroid-dependent or refractory inflammatory bowel disease between March 2008 and March 2017 were included. Primary outcomes were persistence, retention rate, and adverse events; the secondary outcome was the identification of predictors of withdrawal. Ninety-six out of 181 patients (53%) withdrew their first course of adalimumab. The retention rate was 47% and 46.9% in Crohn's disease and ulcerative colitis patients, respectively; median persistence was 26 and 24months in CD and UC patients, respectively. The cumulative probability of treatment persistence was 80.2%, 54.5%, and 29.6% and 69.6%, 40.4%, and 21.5% in CD and UC patients, respectively. The incidence rate of any adverse event was 12.5/100 patients-year; severe adverse events were 1.7/100 patients-year. The Cox regression revealed that CD patients with baseline disease duration > 72months have a higher likelihood for withdrawal due to failure and/or adverse events (HR 1.62, 95% CI 1-2.62, p = 0.04); no predictors of discontinuation were found in UC. Adalimumab showed a great persistence in the first 12months of therapy and excellent safety profile. Early treatment of CD patients could increase efficacy and reduce the adverse event rate.
