[PMID: 38853227 PMCID: PMC11269320 DOI: 10.1007/s10067-024-06971-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 03/27/2024] [Accepted: 04/14/2024] [Indexed: 06/11/2024]
Abstract
INTRODUCTION Optimal adherence thresholds can vary across medications and disease states. The objective of the study was to determine the optimal threshold of the proportion of days covered (PDC) for tumor necrosis factor (TNF) inhibitors in patients with rheumatoid arthritis (RA). METHODS Patients with RA initiating self-administered TNF inhibitors were identified using 2012-18 Medicare fee-for-service claims. Time-varying PDC was calculated every day for the preceding 90 days during follow-up. Oral and injected glucocorticoid use, hospitalizations, emergency room (ER) visits, serious infections, and a composite of these were measured as outcomes. Time to first occurrence of each outcome as a function of time-varying PDC for TNF inhibitors was evaluated using Cox regression. Incident/dynamic time-dependent receiver operating characteristic curves and Youden's J index were used to obtain the optimal PDC threshold for outcomes at 365 days. RESULTS Of the 1190 patients who met the study inclusion criteria, almost 75% (865 patients) experienced at least one of the outcomes. Increasing PDC by 10% was significantly associated with decreased risks of the composite outcome (HR 0.98, 95% CI 0.96-1.00), oral glucocorticoid use (HR 0.93, 95% CI 0.91-0.96), and hospitalization (HR 0.96, 95% CI 0.94-0.99) but an increased risk of ER visits (HR 1.04, 95% 1.01-1.07). Optimal PDC thresholds for the composite outcome, oral glucocorticoid use, and hospitalization were 0.64, 0.59, and 0.56, respectively. CONCLUSIONS Increased PDC was associated with a decreased risk of adverse outcomes, except ER visits. The optimal PDC for TNF inhibitors in Medicare patients with RA based on clinical outcomes was about 60%. Key Points • The optimal proportion of days covered threshold for tumor necrosis factor inhibitors at 365 days based on clinical outcomes was found to be about 60%, which is lower than the traditional 80% used to define adherence. • Increased adherence was associated with decreased risks of oral glucocorticoid use, hospitalization, and the composite outcome. However, it was also associated with an increased risk of emergency room visits. • The mean time-varying 90-day proportion of days covered decreased throughout the study starting 92% at day 1 of follow-up to 62% at day 365.

Insurer-Mandated Medication Utilization Barriers are Associated With Decreased Insurance Satisfaction and Adverse Clinical Outcomes: An Inflammatory Bowel Disease Partners Survey. Am J Gastroenterol 2024:00000434-990000000-01152.

Abstract
INTRODUCTION Insurer-mandated barriers to timely initiation of advanced therapies used to treat inflammatory bowel disease (IBD) have been shown to worsen clinical outcomes and increase healthcare utilization, yet rarely alter the medication ultimately prescribed. METHODS We conducted a survey within the IBD Partners longitudinal cohort to evaluate the frequency and patient-reported impacts of medication utilization barriers on insurance satisfaction and clinical outcomes. Barriers included medication denials, prior authorizations, and forced medication switches. Variables associated with insurance satisfaction, measured on a 1-7 Likert scale, were identified. The association between insurance-related barriers and downstream clinical outcomes (surgery, corticosteroid requirement, and disease activity) were evaluated. RESULTS Two thousand seventeen patients (age 45 [interquartile range 34-58] years, 73% female) were included. Seventy-two percent experienced an insurer-mandated barrier, most commonly prior authorizations (51%). Fifteen percent were denied an IBD medication by their insurer, 22% experienced an insurance-related gap in therapy, and 8% were forced by their insurer to switch from an effective medication. Insurance satisfaction was negatively associated with medication denials, prior authorization-related delays, gaps in therapy, and high-deductible health plan coverage. In the year following the initial survey, several insurance barriers were linked to negative downstream clinical outcomes, including prior authorizations associated with corticosteroid rescue (odds ratio [OR] 2.24, 95% confidence interval [CI] 1.25-4.00), forced medication switches associated with continued disease activity (OR 3.28, 95% CI 1.56-6.89), and medication denials associated with IBD-related surgery (OR 8.92, 95% CI 1.97-40.39). DISCUSSION These data illustrate the frequency and negative impacts of insurer-mandated medication barriers on patients with IBD, including decreased insurance satisfaction and negative downstream clinical outcomes.

Abstract
Background: Understanding risk factors for nonadherence can help specialty pharmacies optimize resources to prevent nonadherence and inform risk-stratification processes. Objective: To determine which individual and community-level characteristics are associated with nonadherence to specialty medications. Methods: We analyzed a cohort of patients enrolled in a prospective randomized controlled trial having filled a specialty medication at least 4 times in the previous 12 months with a proportion of days (PDC) covered < 0.90. We collected patient age, gender, race, medication administration type, therapy start date, home address, insurance type, and online patient portal status from the electronic health record. An ordinal logistic regression model was used to assess the association of nonadherence with individual and community-level patient characteristics. Results: Most patients were female (68%), white (82%), and held commercial insurance (58%) with a median age of 53 (interquartile range [IQR] 40, 64) years. Patients were mostly from the adult rheumatology (35%), multiple sclerosis (20%) and lipid (17%) clinics. Given a 10-year increase in age, patients had lower odds of having lower PDC (odds ratio [OR] = 0.82, 95% confidence interval [CI] = 0.71-0.94, P = 0.005). Patients on therapy greater than or equal to 1 year had half the odds of having lower PDC relative to patients on therapy less than 1 year (OR = 0.52, CI = 0.35 - 0.75, P < 0.001). No statistically significant associations were found between PDC and gender, race, insurance type, route of administration, clinic type, patient portal status, median income, percent receiving government assistance, or percent with no health insurance. Conclusion: Patients with younger age and shorter duration on treatment may be at-risk for lower adherence. Specialty pharmacies may benefit from targeting adherence interventions to these groups.

Abstract
BACKGROUND Increasingly, patient medication adherence data are being consolidated from claims databases and electronic health records (EHRs). Such databases offer an indirect avenue to gauge medication adherence in our data-rich healthcare milieu. The surge in data accessibility, coupled with the pressing need for its conversion to actionable insights, has spotlighted data mining, with machine learning (ML) emerging as a pivotal technique. Nonadherence poses heightened health risks and escalates medical costs. This paper elucidates the synergistic interaction between medical database mining for medication adherence and the role of ML in fostering knowledge discovery. METHODS We conducted a comprehensive review of EHR applications in the realm of medication adherence, leveraging ML techniques. We expounded on the evolution and structure of medical databases pertinent to medication adherence and harnessed both supervised and unsupervised ML paradigms to delve into adherence and its ramifications. RESULTS Our study underscores the applications of medical databases and ML, encompassing both supervised and unsupervised learning, for medication adherence in clinical big data. Databases like SEER and NHANES, often underutilized due to their intricacies, have gained prominence. Employing ML to excavate patient medication logs from these databases facilitates adherence analysis. Such findings are pivotal for clinical decision-making, risk stratification, and scholarly pursuits, aiming to elevate healthcare quality. CONCLUSION Advanced data mining in the era of big data has revolutionized medication adherence research, thereby enhancing patient care. Emphasizing bespoke interventions and research could herald transformative shifts in therapeutic modalities.

Abstract
Objective: Crohn's disease (CD) is an incurable chronic disease that requires long-term treatment. As an anti-tumor necrosis factor (TNF) agent, Infliximab (IFX) is widely used in the treatment of Crohn's disease, while the adherence is not high. The purpose of this study was to investigate the adherence to IFX among CD patients in China and evaluate the association between medication belief and IFX adherence. Methods: Demographic data, clinical information and patients' medication beliefs were collected using an online questionnaire and reviewing electronic medical records (EMRs). The Beliefs about Medicines Questionnaire (BMQ)-specific was used to assess medication beliefs which contains the BMQ-specific concern score and the BMQ-specific necessity score. An evaluation of adherence factors was conducted using univariate and multidimensional logistic regression analyses. Results: In all, 166 CD patients responded the online questionnaire among which 77 (46.39%) patients had high adherence. The BMQ-specific concern score in patients in low adherence was 30.00 and in high adherence patients was 27.50, and patients with lower BMQ-specific concern score had higher adherence (p = 0.013). The multiple regression analysis showed that the BMQ-specific concern score (OR = 0.940, 95% CI: 0.888-0.996) significantly affected the IFX adherence in CD patients. Otherwise, gender, marital status, time spent on the way (including the waiting time in infusion center) and accommodation to the center were also the influencing factors of adherence. Conclusion: The IFX adherence to CD in China was not high. Medicine concerns may be predictive factor of adherence. Education, the duration of IFX therapy and experience of adverse effects were not significantly associated with IFX adherence. By enhancing knowledge and relieving medicine concerns, we may increase patients' adherence to IFX.

Abstract
BACKGROUND Specialty medication nonadherence results in poor clinical outcomes and increased costs. This study evaluated the impact of patient-tailored interventions on specialty medication adherence. METHODS A pragmatic, randomized controlled trial was conducted at a single-center health-system specialty pharmacy from May 2019 to August 2021. Participants included recently nonadherent patients prescribed self-administered specialty medications from multiple specialty clinics. Eligible patients were stratified by historical clinic rates of nonadherence and randomized 1:1 to usual care or intervention arms. Intervention patients received patient-tailored interventions and 8 months of follow-up. A Wilcoxon test was used to analyze the difference in 6-, 8-, and 12-month post-enrollment adherence, calculated using proportion of days covered, between the intervention and usual care arms. RESULTS Four hundred and thirty eight patients were randomized. Baseline characteristics were similar between groups: mostly women (68%), white (82%), with a median age of 54 years (interquartile range, 40, 64). The most common reasons for nonadherence in the intervention arm were memory (37%) and unreachability (28%). There was a significant difference in median proportion of days covered between patients in the usual care and intervention arms at 8-months (0.88 vs 0.94, P < .001), 6-months (0.90 vs 0.95, P = .003), and 12-months post-enrollment (0.87 vs 0.93, P < .001). CONCLUSIONS Patient-tailored interventions resulted in significant specialty medication adherence improvement compared with standard of care. Specialty pharmacies should consider targeting nonadherent patients for adherence interventions.

Abstract
INTRODUCTION AND AIMS The incidence of paediatric inflammatory bowel disease has increased in recent decades. The aim of the present study was to evaluate the role of proactive and serial monitoring of tumour necrosis factor (TNF) inhibitor levels to maintain clinical remission and mucosal healing in the follow-up of paediatric patients with Crohn disease (CD). METHODS Prospective study that included all patients diagnosed with CD and treated with adalimumab or infliximab between May 2015 and November 2020 who underwent serial and proactive monitoring of TNF inhibitor levels. RESULTS The study included 30 patients, 21 male (70%). The mean age at diagnosis was 11.3 years (SD, 2.0), the mean age at initiation of TNF inhibitors was 12.6 years (SD, 1.9) with a mean duration of follow-up of 27.1 ± 9.1 months. Clinical remission was defined as a weighted Pediatric Crohn's Disease Activity Index (wPCDAI) of less than 12.5 and mucosal healing as a Mucosal Inflammation Non-invasive Index (MINI) of less than 8. During the follow-up, patients were in clinical remission in 87.1% of the visits, presented with mild disease in 11.4% and with moderate disease in 1.5%, and mucosal healing was assumed in 83% of the visits. The rates of clinical remission and mucosal healing at 1, 2, and 3 years of follow-up were 83.3%, 95.8%, 92.8%, and 86.7%, 87.5% and 85.7%, respectively. CONCLUSIONS Proactive and serial monitoring of serum TNF inhibitor levels may make it possible for patients to maintain clinical remission and mucosal healing in the maintenance phase, with individualised optimization of the required dosage and minimization of secondary loss of response.

Abstract
BACKGROUND We examined the degree to which adults with inflammatory bowel disease (IBD) integrated their illness into their identity and linked illness identity to important patient-reported outcomes. METHODS A total of 109 adults with IBD, aged 18 to 60 (Mage = 35.93; 77% women) completed questionnaires on the four illness identity dimensions (rejection, acceptance, engulfment, and enrichment), medication adherence, depressive symptoms, life satisfaction, health status, and health-related quality of life (HRQoL). The illness identity scores of adults with IBD were compared to existing data from adults with congenital heart disease (CHD), refractory epilepsy (RE), and multisystemic connective tissue disorders (MSDs) using multivariate analyses of covariance. In adults with IBD, associations between illness identity and patient-reported outcomes were examined through hierarchical regression analyses, controlling for sex, age, illness duration, diagnosis, self-reported flares, and co-existing illnesses. RESULTS Adults with IBD scored higher on rejection and engulfment and lower on acceptance than adults with CHD, lower on rejection but higher on engulfment than adults with RE, and higher on engulfment and enrichment but lower on rejection than adults with MSDs. Higher engulfment scores were related to more depressive symptoms, lower life satisfaction, and a poorer health status and HRQoL. In contrast, higher enrichment scores were related to more life satisfaction and a better HRQoL. Rejection and acceptance were not uniquely related to any of the outcomes. CONCLUSIONS Adults with IBD showed relatively high levels of engulfment. Substantial associations were observed between illness identity and patient-reported outcomes, with engulfment being the strongest, most consistent predictor.

Abstract
Background and Aims This study aimed to evaluate adherence to subcutaneous biologic therapy and impact of nonadherence including risk factors and outcomes in academic centers with integrated specialty pharmacies for patients with inflammatory bowel disease (IBD). Methods This was a multicenter, retrospective cohort analysis of patients aged ≥18 years receiving care in 3 tertiary care outpatient IBD clinics with integrated specialty pharmacies. Subjects were prescribed injectable anti-TNF therapy (adalimumab, certolizumab, golimumab) or anti-IL 12/23 therapy (ustekinumab) with at least 3 consecutive prescription claims. The primary outcomes were medication possession ratio (MPR), percent achieving optimal adherence (MPR > 0.86); in addition, we sought to verify a prior risk factor model including smoking status, narcotic use, psychiatric history, and prior biologic use. Secondary outcomes included emergency department visits (ED) and IBD-related hospitalizations. Statistical analysis was performed using Wilcox rank sum test, Pearson's Chi-squared test, and logistic regression model as an unordered, factor variable to flexibly estimate the probabilities of adherence. Results Six hundred eight subjects were included. Overall median MPR was 0.95 (interquartile range 0.47, 1) and adherence was 68%-70%. When the number of risk factors for nonadherence increased, the likelihood of nonadherence increased (P < .05). In unadjusted and adjusted analysis, nonadherence increased the likelihood of ED visits [rate ratio 1.45 (95% confidence interval 1.05, 1.97)] and hospitalizations [rate ratio 1.60 (95% confidence interval 1.16, 2.10)]. Conclusion Academic centers with integrated pharmacies had high adherence. Prior risk factors for nonadherence remained significant in this multicenter model. Nonadherence was associated with higher likelihood of hospitalizations and ED visits.

Unplanned pregnancies are common; therefore, efforts to maximise adherence should not be restricted to pregnant women. OBJECTIVES We aimed to assess medication adherence in women with IBD of childbearing age, regardless of their reproduction plans. DESIGN We performed a multi-centre pilot questionnaire study of women with IBD age 18-45 years. METHODS Survey questions included patient demographics, disease history, and validated assessments of IBD and pregnancy knowledge, medication adherence and quality of life. The primary outcome was rates and predictors of medication adherence. RESULTS In all, 72 women [58.3% Crohn's disease (CD) and 37.5% ulcerative colitis] completed the survey. The median patient age was 30 years [interquartile range (IQR): 24.8-36.0) and 37.5% had children. Medication adherence was high (84%; median Medication Adherence Report Scale: 19.0/20; IQR: 17.0-20.0). Knowledge scores were adequate for both the Crohn's and Colitis Knowledge (CCKnow; median: 15.5/30; IQR: 12.3-18.0) and Crohn's and Colitis Pregnancy Knowledge (CCPKnow; median: 8.0/17; IQR: 4.0-11.0). Disease knowledge was predictive of high medication adherence (CCPKnow: p = 0.02; CCKnow: p ⩽ 0.01). Higher adherence was significantly associated with a diagnosis of CD (p = 0.01), exposure to biological agents (p = 0.03) and immunomodulators (p = 0.04), childbearing after diagnosis with IBD (p = 0.03), and correctly understanding the importance of delivery modality (p = 0.02) and IBD activity in pregnancy (p = 0.01). CONCLUSIONS Following dedicated education at the IBD clinic, medication adherence, disease-specific and pregnancy-specific knowledge in women with IBD of childbearing age tends to be high. Unplanned pregnancies are frequent; therefore, we should aim to maximise medication adherence in all women of childbearing age to optimise maternofoetal outcomes if unexpected pregnancies occur.

Delaying an infliximab infusion by more than 3 days is associated with a significant reduction in trough levels but not with clinical worsening. Therap Adv Gastroenterol 2022; 15:17562848221083395. [PMID: 35646158 PMCID: PMC9133860 DOI: 10.1177/17562848221083395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 02/08/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Higher infliximab trough levels (TLs) correlate with better clinical, inflammatory, and endoscopic outcomes among inflammatory bowel disease (IBD) patients. Although standard scheduled infliximab therapy regimen consists of infusions at pre-defined time-points (weeks 0, 2, 6, and every 8 weeks), short-period deviations from therapeutic schedule are common in 'real life', but the pharmacokinetic impact of these deviations has not been explored. In this study, we aim to determine whether short-period deviations from infusion schedule affect infliximab-TL. METHODS A retrospective analysis of all IBD patients receiving infliximab maintenance therapy every 8 weeks was conducted in a tertiary medical center. Patients with anti-drug antibodies, deliberate interval shortening and <3 sequential maintenance sera available were excluded. Associations between time since last infusion and TL were studied. Statistical analysis was performed using generalized estimating equations. RESULTS Out of over 10,000 sera, 2088 sera of 302 maintenance period stable infliximab-therapy-patients met inclusion criteria (median TL 4.1 μg/mL, interquartile range (IQR) 2.3-6.5 μg/mL). A delay beyond 3 days in infusion schedule (n > 59 days since last infusion) was found to significantly affect TL (mean difference in TL 0.9 μg/mL, 95% confidence interval (CI): 0.03-1.9 μg/mL, p < 0.04). Furthermore, among patients with delayed infusions, 80% had TL below 5 μg/mL, in comparison to 55% of patients who were not late (odds ratio (OR): 2.81, CI: 2.02-3.92, p < 0.0001). CONCLUSION Real-life delays of ⩽3 days from infusion protocol can probably be allowed. Delays >3 days culminate in measurable decrease of TL, although effect on clinical outcome is unclear. This needs to be taken into account when interpreting drug-level test results. SUMMARY A total of 2088 sera of 302 maintenance period inflammatory bowel disease (IBD) patients treated with infliximab were analyzed, to assess effect of small deviations from infusion schedule on TLs. A significant decline in patients' trough level (TL) was noted as early as 3 days after scheduled infusion.

COVID-19 Pandemic Increased Anxiety Among Patients with Inflammatory Bowel Disease: A Patient Survey in a Tertiary Referral Center. Dig Dis Sci 2022; 67:2876-2881. [PMID: 34115232 PMCID: PMC8193011 DOI: 10.1007/s10620-021-07095-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 06/02/2021] [Indexed: 01/18/2023]
Abstract
BACKGROUND COVID-19 is the first global pandemic in more than 100 years, and at its onset, the effects were largely unknown. Immunocompromised patients, including IBD, were presumed to have higher risk. AIMS We hypothesized patients with IBD would have higher-than-baseline anxiety, high perceived vulnerability and significant lifestyle impacts as a result of the pandemic. We sought to assess the impact of these changes on disease and management. METHODS A cross-sectional study of patients with Crohn's disease, ulcerative colitis and IBD-unspecified was conducted. Patients were invited to participate by email in an IRB-approved brief, voluntary survey. Survey questions focused on disease characteristics, healthcare access and self-reported psychological well-being. RESULTS Responses from 492 (CD = 337, UC = 141,IC = 14) patients were included in the analysis. The majority of patients with IBD had increased anxiety since the pandemic, which correlated with an increase in GI symptoms. This risk of symptoms was mitigated by communication with their provider. Many patients had lifestyle changes including requesting time off work due to perceived vulnerability and changes in eating habits. CONCLUSIONS Our findings support an increase in illness-associated anxiety and perceived vulnerability among patients with IBD during the COVID-19 pandemic. Open communication with providers is important to maintain adequate control of disease and reduce symptoms of flares triggered by ongoing stress.

Abstract
Despite the fact that the prognosis of chronic inflammatory disorders is improved by biological agents, compliance with those therapeutics remains imperfect. Compliance corresponds to the measurable part of the follow-up of the medical prescription by the patient, whereas adherence is related to the acceptation of the treatment by the patient. The compliance rates of biologic agents are generally higher than those of conventional therapies. Compliance can be influenced by the real or experienced efficacity of the treatment, by patient-related factors or by the patient-physician relationship. An increase of compliance is associated with an improvement of adherence. To achieve this, the physician can use educational measures such as patient education, which allows the identification of poor adherence. Such programs have been shown to improve the patient's knowledge of the disease and treatment leading to better adherence and compliance.

Abstract
BACKGROUND Nonadherence to medication is common in patients with inflammatory bowel disease (IBD) and can result in disease complications, therapy escalation, and the need for corticosteroids. The aim of this study was to assess the adherence to self-administered subcutaneous biologic medications prescribed for IBD and to identify the risk factors for nonadherence. METHODS A retrospective cohort study on IBD patients initiated on subcutaneous biologic therapy between January 2016 and July 2019 was performed. Medical records were retrospectively reviewed for collection of demographic and IBD data. Medication possession ratios (mMPRs) during the first 12 months of treatment and at the end of the follow-up period (global, 42 months) were calculated. Nonadherence was defined as an mMPR of <90%. Multiple regression analysis was performed to assess the risk factors for nonadherence to therapy. RESULTS A total of 154 patients (84 male and 70 female; mean age at biologic treatment initiation, 36±14 years; Crohn's disease, n=118; ulcerative colitis, n=31; indeterminate colitis, n=5) were included; 121 received adalimumab (ADA) and 33 received ustekinumab (UST); 63% were naive to anti-TNF therapy, while 16.9% previously received more than two biologic treatments. Mean time from IBD diagnosis to subcutaneous biological agent use was 16±10 months. Mean duration of subcutaneous agent use was 17.6 (SD, 11.0) and 17.08 (SD, 6.8) months for ADA and UST, respectively. Global nonadherence (mMPR≤90%) rate was 6.6% for all patients receiving subcutaneous treatment, 6.3% for ADA, and 6.5% for UST. Nonadherence during the first 12 months of treatment (n=98) was 6.1% for all patients, 2.7% for ADA, and 16% for UST. In the multivariate analysis, UST use was independently associated with higher nonadherence only within the first 12 months (OR, 6.7; 95% CI, 1.1-39.5). CONCLUSIONS High global adherence to self-administered subcutaneous biologic treatment was shown in our study, with higher rates of adherence to ADA than to UST within the first 12 months.

Sustained long-term benefits of patient support program participation in immune-mediated diseases: improved medication-taking behavior and lower risk of a hospital visit. J Manag Care Spec Pharm 2021; 27:1086-1095. [PMID: 33843252 PMCID: PMC10394214 DOI: 10.18553/jmcp.2021.20560] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/05/2022]
Abstract
BACKGROUND: Patient support programs (PSPs) improve medication-taking behavior in the first 12 months of treatment for patients with immune-mediated diseases, but it is unknown if these benefits are sustained. As immune-mediated diseases continue to increase in prevalence and economic burden, understanding the potential value of PSPs in helping patients adhere to their long-term treatment plan and avoid costly hospital visits is crucial. Launched nationally in 2015, HUMIRA Complete (a PSP for adalimumab patients) provides an opportunity to study long-term effects of PSP participation, including the impact on medication-taking behavior and hospital visits. OBJECTIVE: To evaluate the sustained relationship between PSP participation, long-term medication-taking behavior, and hospital visits. METHODS: A longitudinal, retrospective matched-cohort study was conducted of patients initiating adalimumab between January 2015 and February 2016 with or without enrolling in the PSP, using patient-level data from the HUMIRA Complete PSP linked with Symphony Health claims. The sample included adult, commercially insured patients diagnosed with an indicated disease who were biologic-naive and had data available for ≥ 6 months before and ≥ 12 months after initiating adalimumab. Adherence (proportion of days covered) and hospital visits were assessed at 12, 24, and 36 months for patients with sufficient follow-up data. Multivariable generalized models estimated differences between cohorts, controlling for baseline characteristics and hospital visits. Duration of persistence and time to a hospital visit were compared using Kaplan-Meier analyses. Hazard ratios were estimated using multivariable Cox proportional hazards models. RESULTS: The matched cohort included 2,268 patients (1,134 per cohort), and patient attrition was similar across cohorts. The PSP cohort consistently demonstrated higher adalimumab adherence than the non-PSP cohort at 12 (64.8% vs. 50.1%, P < 0.0001; 29% greater), 24 (49.4% vs. 38.4%; P < 0.0001; 29% greater), and 36 (39.4% vs. 35.1%; P = 0.02; 12% greater) months. PSP participation was associated with a 30% lower hazard of discontinuation (P < 0.0001), and median duration of persistence was 4.8 months longer for the PSP cohort (13.2 vs. 8.4 months; P < 0.0001). The PSP cohort had lower rates of hospital visits at 12 (30% vs. 37%; P < 0.001; 19% lower), 24 (44% vs. 53%; P = 0.01; 17% lower), and 36 (55% vs. 65%; P < 0.01; 16% lower) months, and PSP participation was associated with a 25% lower hazard of a hospital visit (P < 0.0001). Median time to a hospital visit was 10.8 months longer for the PSP cohort (32.7 vs. 21.9 months; P < 0.0001). Findings were consistent across therapeutic areas: hazard of a hospital visit was 28%, 27%, and 37% lower for rheumatology, gastroenterology, and dermatology patients participating in the PSP (all P < 0.05). CONCLUSIONS: Patients with immune-mediated diseases receiving adalimumab and utilizing this PSP had improved long-term medication-taking behavior and lower risk of hospital visits, demonstrating the potential of PSPs to improve patient outcomes and lower the burden to the health care system.

Abstract
BACKGROUND Chronic opioid use is associated with poorer clinical outcomes in inflammatory bowel disease. AIMS To investigate an association between chronic opioid use and persistence with biologic agents in management of inflammatory bowel disease. METHODS A total of 16 624 patients diagnosed with inflammatory bowel disease and receiving a first-time biologic prescription from 2011 to 2016 were identified retrospectively from the Truven MarketScan Database. A cohort of 1768 patients were identified as chronic opioid users utilising outpatient prescription claims. Utilisation patterns of biologic therapies were assessed from inpatient administration and outpatient claims data, including persistence calculations. Information on healthcare utilisation and common comorbidities was also collected. A Cox regression model was constructed to assess the hazard of chronic opioid use on early discontinuation of biologic therapy controlling for disease severity. RESULTS A mean 1.5 different biologic agents were utilised by inflammatory bowel disease patients with chronic opioid use (vs 1.37 in the comparator group; P < 0.0001). A lower proportion of the chronic opioid use cohort persisted on biologic therapies to the end of the study period (16.2% vs 33.5% P < 0.0001). Inflammatory bowel disease patients with chronic opioid use utilised more healthcare resources and had a higher rate of comorbidities than the reference cohort. Patients with chronic opioid use were 23% more likely (hazard ratio 1.23; 95% CI [1.16-1.31]) to be non-persistent with biologic therapy while accounting for relevant markers of disease acuity. CONCLUSIONS Chronic opioid use is associated with increased hazard of biologic discontinuation in inflammatory bowel disease. Symptoms of opioid withdrawal may mimic IBD flares thereby leading providers to inappropriately switch biologic therapies and compromise disease control.

Abstract
Aim: To assess adherence to subcutaneous biologicals in adults with inflammatory rheumatic diseases or inflammatory bowel disease and evaluate factors possibly associated with adherence. Materials & methods: Systematic searches were conducted of main databases from January 2000 to June 2019. Results: 41 articles (32 full papers and nine abstracts) were included in the review. Among studies which used a medication possession ratio threshold of ≥80% as the end point, adherence varied from 28.8 to 89.4%. Possible predictors of adherence were older age, professional or family member support, belief in medication necessity, lower concerns about medication and monthly versus weekly administration. Conclusion: Considerable variability in adherence rates across published studies reflects study heterogeneity and the absence of a 'gold standard' to measure adherence.

Abstract
IMPORTANCE Crohn disease, a chronic gastrointestinal inflammatory disease, is increasing in incidence and prevalence in many parts of the world. Uncontrolled inflammation leads to long-term complications, including fibrotic strictures, enteric fistulae, and intestinal neoplasia. Therefore, early and effective control of inflammation is of critical importance. OBSERVATIONS The optimal management approach for Crohn disease incorporates patient risk stratification, patient preference, and clinical factors in therapeutic decision-making. First-line therapy generally consists of steroids for rapid palliation of symptoms during initiation of anti-tumor necrosis factor α therapy. Other treatments may include monoclonal antibodies to IL-12/23 or integrin α4β7, immunomodulators, combination therapies, or surgery. Effective control of inflammation reduces the risk of penetrating complications (such as intra-abdominal abscesses and fistulae), although more than half of patients will develop complications that require surgery. Adverse reactions to therapy include antibody formation and infusion reactions, infections, and cancers associated with immune modulators and biologics and toxicity to the bone marrow and the liver. Both Crohn disease and corticosteroid use are associated with osteoporosis. Vaccinations to prevent infections, such as influenza, pneumonia, and herpes zoster, are important components of health maintenance for patients with Crohn disease, although live vaccines are contraindicated for patients receiving immune suppression therapy. CONCLUSIONS AND RELEVANCE The treatment of patients with Crohn disease depends on disease severity, patient risk stratification, patient preference, and clinical factors, including age of onset and penetrating complications, and includes treatment with steroids, monoclonal antibody therapies, immunomodulators, and surgery. Physicians should be familiar with the advantages and disadvantages of each therapy to best counsel their patients.

Adherence to Adalimumab Was Not Improved by a Reminder-Based Intervention with an Electronic Needle Container. Dig Dis Sci 2021; 66:1477-1487. [PMID: 32556818 PMCID: PMC8053164 DOI: 10.1007/s10620-020-06395-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Accepted: 06/03/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Adherence to adalimumab in inflammatory bowel disease (IBD) patients is reported to be below par. Non-adherence may result in loss-of-response and increased hospitalization. We analyzed the effect of an electronic needle container (ENC) on adherence to adalimumab. METHODS In this multicenter, 12-months observational study, we included adalimumab treated IBD patients. All patients were invited to receive an ENC. Patients who declined or did not complete the registration for an ENC served as controls. Primary endpoint was whether an ENC increased adherence, calculated from pharmacy refills as proportion of days covered (PDC). Secondary endpoints were clinical outcomes, including loss-of-response, identification of predictors of adherence and correlation between different modalities for measuring adherence. Loss-of-response was defined as a disease flare, dose-escalation or IBD-related hospitalization or surgery. RESULTS The pharmacies' records identified 198 eligible patients, of whom 32 were excluded. The ENC was supplied to 69 patients, the remaining 97 patient formed the control group. Median baseline PDC (98.4% vs. 96.1%, p = 0.047) and the proportion of adherent (PDC ≥ 86%) patients (87.0% vs. 74.2%, p = 0.045) was higher for the ENC group. The ENC did not improve the adherence of patients during follow-up (odds ratio 1.26, 95% CI 0.55-2.86). During follow-up, five (7.2%) patients in the ENC group and 13 (13.4%) in the control group discontinued adalimumab (log-rank p = 0.22). Loss-of-response occurred in 12 (17.4%) and 14 (14.4%) patients, respectively (log-rank p = 0.66). CONCLUSIONS Our results show no beneficial effect of a reminder-based intervention on adherence or treatment outcomes.

Haar GS, Vasudevan A, Curtain CM, van Langenberg DR. Assessing adherence to infusion-based biologic therapies in patients with inflammatory bowel disease. Res Social Adm Pharm 2020; 17:1420-1425. [PMID: 33129684 DOI: 10.1016/j.sapharm.2020.10.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 10/14/2020] [Accepted: 10/19/2020] [Indexed: 01/06/2023]
Abstract
BACKGROUND The intravenous biologics infliximab and vedolizumab are effective long-term therapies for inflammatory bowel disease (IBD). Though highly effective, suboptimal adherence may result in loss of response and adverse sequelae. The extent and outcomes of suboptimal adherence with intravenous biologics, including in IBD, requires further evaluation. OBJECTIVES To ascertain adherence to infliximab and vedolizumab infusions, and determine factors associated with poorer adherence within an IBD cohort. METHODS A retrospective single-centre cohort study of IBD patients, assessing adherence to infliximab and vedolizumab over 2 years (July 1, 2017 to June 30, 2019) was conducted. Medical and pharmacy dispensing records were used to determine date of infusion. Adherence was assessed using the continuous, multiple interval measure of medication gaps (CMG). Objectively measured disease remission was achieved if one or more of endoscopic remission, faecal calprotectin <100 μg/mL and/or CRP <5 mg/mL occurred within 3 months of end of follow-up. Bivariate analysis and multiple linear regression elucidated factors associated with poorer adherence. RESULTS Of 193 IBD patients, 132 (68.4%) had Crohn's disease. One hundred and thirty six (70.5%) patients received infliximab and 57 (29.5%) received vedolizumab with a median 13 [IQR 11-14] doses administered per patient over 2 years. Adherence according to CMG was similar between infliximab and vedolizumab groups (median 1.5% vs 1.2%, p = 0.31). In multiple linear regression analysis male sex, shorter IBD duration and clinic non-attendances were each associated with poorer adherence (Beta 4.69, 3.90, 3.56 respectively, p < 0.05) and objective disease remission was inversely associated with poorer adherence (Beta -3.27, p < 0.05). CONCLUSION There was a wide range of adherence to biologic infusions in this IBD cohort with poorer adherence associated with patient related factors. Conversely, objectively measured remission was strongly associated with adherence. This emphasises the need for targeted interventions to improve adherence and monitoring, and mitigate treatment delays.

Abstract
BACKGROUND The effectiveness of specialty medications in complicated clinical conditions depends on adherence to therapy. However, specialty medications pose unique barriers to adherence. OBJECTIVE This study aims to determine whether pharmacist interventions improve specialty medication adherence. METHODS This is a single-center, pragmatic, randomized controlled trial ongoing since 10 May 2019 at an integrated health system specialty pharmacy. This study evaluates usual care compared with usual care plus patient-tailored adherence interventions. Study design and procedures were informed by focus groups with patients and specialty pharmacists. Patients at Vanderbilt Specialty Pharmacy with a proportion of days covered (PDC) < 90% in the previous 4 months are identified by a daily query of the electronic pharmacy database. A pharmacist reviews these patients' electronic health records to identify and exclude ineligible patients. Eligible patients are randomized evenly to the control or intervention arm and stratified by historical clinic nonadherence rates. Patients randomized to the intervention arm undergo a baseline assessment to clarify reasons for nonadherence and subsequently receive patient-tailored interventions based on their specific reasons. Interventions and follow-up are provided at the discretion of the intervening pharmacist. The primary outcome is PDC calculated at 8 months post-enrollment. Enrollment of 438 participants will provide 90% power to detect a 5% difference in PDC between the two arms within each nonadherence risk stratum. DISCUSSION This trial will evaluate the effect of patient-tailored interventions on specialty medication adherence and will inform how often and why patients are misidentified as nonadherent. REGISTRATION The trial was deemed a quality improvement initiative by the Vanderbilt University Institutional Review Board. It was registered in ClinicalTrials.gov (NCT03709277) on 17 October 2018.

Abstract
BACKGROUND In inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), nonadherence to biologic therapy increases risk of disease flare. The aim of this study was to identify risk factors for nonadherence. METHODS This was a single-center retrospective study evaluating patients with IBD treated at a tertiary care center and prescribed self-injectable biologic therapy using the center's specialty pharmacy. Adherence was defined using medication possession ratio (MPR). Nonadherence was defined as MPR <0.86. RESULTS Four hundred sixty patients (n = 393 with CD and n = 67 with UC) were evaluated with mean MPR (interquartile range) equaling 0.89 (0.48-1). Overall, 69% of patients were adherent (defined as MPR ≥0.86), 66% of patients with CD and 87% of patients with UC. In univariate analysis, several factors increased risk of nonadherence: CD diagnosis, insurance type, psychiatric history, smoking, prior biologic use, and narcotic use (P < 0.05). In multivariable analysis, Medicaid insurance (odds ratio [OR], 5.5; 95% confidence interval [CI], 1.85-15.6) and CD diagnosis (OR, 2.8; 95% CI, 1.3-6.0) increased risk of nonadherence. In CD, as the number of risk factors increased (narcotic use, psychiatric history, prior biologic use, and smoking), the probability of nonadherence increased. Adherence was 72% in patients with 0-1 risk factors, decreasing to 62%, 61%, and 42% in patients with 2, 3, and 4 risk factors, respectively (P < 0.05). CONCLUSIONS This study identified risk factors for nonadherence to biologic therapy. In patients with CD, the probability of nonadherence increased as the number of risk factors increased.

Abstract
BACKGROUND Adherence to specialty and nonspecialty medications is often calculated using pharmacy claims data. However, specialty medication regimens are complex and may require periods of intentional gaps in therapy. Common adherence calculations are insufficient in identifying reasons for gaps in therapy. Because adherence reporting is a growing measure of quality care for specialty pharmacy accreditation and payer and manufacturer contracts, a better understanding of the rates and reasons for nonadherence within a specialty population is needed. OBJECTIVE To identify rates and reasons for misidentified and true nonadherence in patients who are prescribed specialty medications. METHODS A single center, retrospective cohort study was conducted using pharmacy claims data between March 2017 and February 2018. Medication adherence was calculated using proportion of days covered (PDC). Electronic medical records of a random 10% sample of nonadherent patients (PDC < 80%) were manually reviewed to identify reasons for nonadherence. Patients were then classified as either (a) misidentified as nonadherent (i.e., a provider-directed discontinuation or disruption of treatment that varies from the prescribed administration schedule or transfer of the prescription to an external pharmacy) or (b) truly nonadherent (discontinuation or disruption of treatment that varies from the prescribed administration instruction that is not directed or recommended by the provider or health care team). RESULTS Of the 7,488 included prescription records from 18 specialty areas, 1,059 met criteria for nonadherence. 105 prescription records (representing 105 unique patients) were manually reviewed; most of these patients (58%) were truly nonadherent, driven by inability to contact patients for refills (59%). However, 40% were misidentified as nonadherent, most due to provider-directed medication holding (69%). Two percent of patients were nonadherent for unknown reasons. CONCLUSIONS Many patients classified as nonadherent based on pharmacy claims experienced gaps in therapy due to medically appropriate reasons. Methods to better measure and identify true nonadherence are needed to efficiently and adequately affect specialty medication adherence behavior.

Abstract
PURPOSE The development of a tool to measure medication safety, therapeutic efficacy, and other quality outcomes in patients receiving self-injectable biologic therapy for the management of inflammatory bowel disease (IBD) at a health-system specialty pharmacy is described. SUMMARY Through a collaborative initiative by pharmacists, gastro-enterologists, and representatives of a pharmacy benefit manager and a pharmaceutical company, a set of clinical and specialty pharmacy quality measures was developed. The clinical measures are intended for use in assessing patient safety, disease status, treatment efficacy, and healthcare resource utilization during 3 assessments (pre-treatment, on-treatment, and longitudinal). The specialty pharmacy measures can be used to assess medication adherence, medication persistence, specialty pharmacy accreditation, and patient satisfaction. The proposed quality measures provide a foundation for evaluating the quality of IBD care and improving patient outcomes within a health-system specialty pharmacy. Future efforts to validate and implement the tool in clinical practice are planned. CONCLUSION The proposed quality measures provide a foundation for future inquiry regarding the appropriateness and feasibility of integrating the measures into clinical care. Further work is needed to implement and validate these quality measures and determine their impact in optimizing health outcomes.

Abstract
Medication adherence is a well-recognized problem in the management of patients with chronic diseases needing a long-term pharmacotherapy. While fighting against non-adherence, an important question frequently arises, i.e., how much adherence is enough to obtain the full treatment benefits? Most studies having attempted to answer this question have used large pharmacy records and health care databases to quantify the percentage of days covered by the prescribed treatment and hence deduce a threshold below which there appears to be fewer benefits from therapy. In the present paper, the use of data obtained using electronic monitoring of adherence is discussed as another means to assess adherence thresholds with a particular emphasis on hypertension. The data show that even with the use of electronic monitoring of adherence, which provides a comprehensive dosing history, it is extremely difficult to define an adherence threshold in hypertension. This is due to many factors that need to be taken into account, including not only the pattern of patients’ adherence and their clinical and environmental characteristics, but also the pharmacological characteristics of the prescribed drugs, the severity of the disease and many others. To determine adherence cut-offs more precisely, specific protocols should be designed to answer the question in various clinical conditions. These protocols should be conducted in well-defined patients’ groups, they should use the most reliable methods to measure adherence providing if possible a detailed dosing history perhaps combined with drugs levels in blood or urine. These studies should also choose the best methods to measure clinical endpoints, such as ambulatory blood pressure monitoring or home blood pressure in the case of hypertension. One important aspect is that datasets should be solid and large enough to be able to analyze adherence data as a continuous variable using newly developed mathematical models including new metrics catching the complexity of adherence. The rapid development of new technologies like devices, connectivity, and analytics, will probably provide new solutions to improve our ability to define valid and clinically useful adherence thresholds in various therapeutic areas.

Abstract
OBJECTIVES Identify predictors of persistence with adalimumab (ADA) among veterans and privately insured patients with inflammatory bowel disease (IBD) in the United States. STUDY DESIGN Retrospective cohort study. METHODS Patients with IBD taking ADA as their first biologic were identified from the Veterans Health Administration (VHA) database from 2009 to 2013 and the Truven Health MarketScan database from 2009 to 2012 with a 12-month follow-up. Persistence was defined as continued use 1 year after initiation. Adherence was assessed by calculating a medication possession ratio, which was dichotomized as greater than 0.86 or less than or equal to 0.86. Multivariable logistic regression was used to evaluate predictors of persistence. RESULTS There were 1030 patients in the VHA population compared with 3264 patients in the privately insured (MarketScan) cohort. In MarketScan, 1800 patients (55%) remained on ADA compared with 755 (73%) in the VHA cohort. In multivariable analysis, male sex (odds ratio [OR], 1.38; 95% CI, 1.16-1.63; P <.01), Crohn disease (OR, 1.27; 95% CI, 1.02-1.57; P = .03), greater adherence (OR, 1.83; 95% CI, 1.45-2.30; P <.01), and dose escalation (OR, 1.82; 95% CI, 1.42-2.33; P <.01) were associated with higher ADA persistence in the MarketScan cohort; narcotic use (OR, 0.71; 95% CI, 0.58-0.88; P <.01) and hospitalization or new steroid use after initiation (OR, 0.04; 95% CI, 0.03-0.05; P <.01) were associated with lower persistence. In the VHA cohort, only a hospitalization or new steroid use (OR, 0.50; 95% CI, 0.36-0.70; P <.01) was associated with lower persistence. CONCLUSIONS Despite being older and having more comorbidities, patients in the VHA, which is an integrated healthcare system, appear to be more likely to remain on ADA at 1 year than patients in the MarketScan database. Further studies of system differences are needed to understand the reasons behind this discrepancy.

Abstract
Background: In pharmacotherapy, the achievement of a target clinical outcome requires a certain level of medication intake or adherence. Based on Haynes's early empirical definition of sufficient adherence to antihypertensive medications as taking ≥80% of medication, many researchers used this threshold to distinguish adherent from non-adherent patients. However, we propose that different diseases, medications and patient's characteristics influence the cut-off point of the adherence rate above which the clinical outcome is satisfactory (thereafter medication adherence threshold). Moreover, the assessment of adherence and clinical outcomes may differ greatly and should be taken into consideration. To our knowledge, very few studies have defined adherence rates linked to clinical outcomes. We aimed at investigating medication adherence thresholds in relation to clinical outcomes. Method: We searched for studies that determined the relationship between adherence rates and clinical outcomes in the databases PubMed, EmbaseⓇ and Web of Science™ until December 2017, limited to English-language. Our outcome measure was any threshold value of adherence. The inclusion criteria of the retrieved studies were (1) any measurement of medication adherence, (2) any assessment of clinical outcomes, and (3) any method to define medication adherence thresholds in relation to clinical outcomes. We excluded articles considered as a tutorial. Two authors (PB and IA) independently screened titles and abstracts for relevance, reviewed full-texts, and extracted items. The results of the included studies are presented qualitatively. Result: We analyzed 6 articles that assessed clinical outcomes linked to adherence rates in 7 chronic disease states. Medication adherence was measured with Medication Possession Ratio (MPR, n = 3), Proportion of Days Covered (PDC, n = 1), both (n = 1), or Medication Event Monitoring System (MEMS). Clinical outcomes were event free episodes, hospitalization, cortisone use, reported symptoms and reduction of lipid levels. To find the relationship between the targeted clinical outcome and adherence rates, three studies applied logistic regression and three used survival analysis. Five studies defined adherence thresholds between 46 and 92%. One study confirmed the 80% threshold as valid to distinguish adherent from non-adherent patients. Conclusion: The analyzed studies were highly heterogeneous, predominantly concerning methods of calculating adherence. We could not compare studies quantitatively, mostly because adherence rates could not be standardized. Therefore, we cannot reject or confirm the validity of the historical 80% threshold. Nevertheless, the 80% threshold was clearly questioned as a general standard.

Abstract
Background Opioids are commonly prescribed for relief in inflammatory bowel disease (IBD). Emerging evidence suggests that adolescents and young adults are a vulnerable population at particular risk of becoming chronic opioid users and experiencing adverse effects. Objectives This study evaluates trends in the prevalence and persistence of chronic opioid therapy in adolescents and young adults with IBD in the United States. Method A longitudinal retrospective cohort analysis was conducted with the Truven MarketScan Database from 2007 to 2015. Study subjects were 15-29 years old with ≥2 IBD diagnoses (Crohn's: 555/K50; ulcerative colitis: 556/K51). Opioid therapy was identified with prescription claims within the Truven therapeutic class 60: opioid agonists. Persistence of opioid use was evaluated by survival analysis for patients who remained in the database for at least 3 years following index chronic opioid therapy use. Results In a cohort containing 93,668 patients, 18.2% received chronic opioid therapy. The annual prevalence of chronic opioid therapy increased from 9.3% in 2007 to 10.8% in 2015 (P < 0.01), peaking at 12.2% in 2011. Opioid prescriptions per patient per year were stable (approximately 5). Post hoc Poisson regression analyses demonstrated that the number of opioid pills dispensed per year increased with age and was higher among males. Among the 2503 patients receiving chronic opioid therapy and followed longitudinally, 30.5% were maintained on chronic opioid therapy for 2 years, and 5.3% for all 4 years. Conclusion Sustained chronic opioid use in adolescents and young adults with IBD is increasingly common, underscoring the need for screening and intervention for this vulnerable population.
