Knowledge about Disease, Medication Therapy, and Related Medication Adherence Levels among Patients with Hypertension.

Background and Objectives: A particular problem in cardiology is poor adherence to pharmacological treatment among patients with hypertension. It is known that approximately half of these patients do not use their medications as prescribed by their doctor. Patients may choose not to follow the doctor’s recommendations and regularly do not control their blood pressure, owing to many factors. A convenient method for measuring the level of adherence is the Morisky Medication Adherence Scale, which also provides insight into possible remedies for low adherence. We investigated their therapy, knowledge about the disease and its control, and demographic differences to assess the adherence of patients with hypertension. Materials and Methods: This was a cross-sectional observational study. Data were collected through a survey of 12 pharmacies in Latvia. The study involved 187 participants with hypertension. Results: The prevalence of non-adherence was 46.20% in Latvia. The oldest patients were the most adherent (p = 0.001, β = 0.27). The higher the self-rated extent from 0 to 10, to which the patient takes their antihypertensives exactly as instructed by their physician, the higher the level of adherence (p < 0.0001, β = 0.38), where at “0”, the patient does not follow physician instructions at all, and at “10”, the patient completely follows the physician’s instructions. Non-adherent patients tend to assess their medication-taking behavior more critically than adherent patients. The longer the patient is known to suffer from hypertension, the more adherent he or she is (p = 0.014, β = 0.19). Conclusions: Medication non-adherence among patients with hypertension is high in Latvia. Further investigations are needed to better understand the reasons for this and to establish interventions for improving patient outcomes.

Implicit and explicit attitudes towards disease-modifying antirheumatic drugs as possible target for improving medication adherence.

ObjectiveThis study aims to explore the contribution of implicit attitudes and associations towards conventional disease-modifying antirheumatic drugs (cDMARDs), alongside explicit measures, on medication-taking behaviour and clinical outcomes in adult patients with rheumatoid arthritis (RA).MethodsIn this observational study, implicit attitudes (positive-negative) and health-related associations (health-sickness) were measured with Single Category Implicit Association Tests, whereas explicit outcomes were measured with a bipolar evaluative adjective scale and the Beliefs about Medicines Questionnaire Specific. The primary outcome of this study was medication-taking behaviour subjectively measured by self-report (i.e. validated Compliance Questionnaire on Rheumatology) and objectively measured with electronic drug monitors over a 3 month period. Spearman rank correlations were used to describe correlations between implicit and explicit outcomes. Nested linear regression models were used to assess the additional value of implicit measures over explicit measures and patient-, clinical-, and treatment-related characteristics.ResultsOf the 1659 initially-invited patients, 254 patients with RA agreed to participate in this study. Implicit attitudes correlated significantly with necessity-concerns differential (NCD) scores (ρ = 0.13, P = 0.05) and disease activity scores (ρ = -0.17, P = 0.04), whereas implicit health-related associations correlated significantly with mean scores for explicitly reported health-related associations (ρ = 0.18, P = 0.004). Significant differences in age, number of DMARDs, biologic DMARD use, NCD-scores, and self-reported correct dosing were found between the four attitudinal profiles. Nested linear regression models revealed no additional value of implicit measures in explaining self-reported medication-taking behaviour and clinical outcomes, over and above all other variables.ConclusionImplicit attitudes and associations had no additional value in explaining medication-taking behaviour and clinical outcomes over and above often used explicitly measured characteristics, attitudes and outcomes in the studied population. Only age and NCD scores contributed significantly when the dependent variable was correct dosing measured with self-report.

Developing Preliminary Steps in a Pharmacist Communication – Patient Outcome Pathway

Nonadherence to medication therapy has been associated with poor health outcomes and increased health care costs. The literature describes pharmacists as key health care professionals in identifying and addressing nonadherence issues but does not explain how and why effective pharmacist-patient communication affects patients' medication adherence. Previously published pathways used in linking effective physician-patient communication to patient outcomes are proposed for the context of pharmacist-patient communication. To develop preliminary steps in a pharmacist communication - patient outcome pathway, adapted from a physician-patient communication pathway. This longitudinal descriptive study, which took place in a large quaternary hospital, involved hospital pharmacists and patients. Patients' assessment of pharmacist communication behaviours and reporting of patient satisfaction occurred after the pharmacist-patient consultation. Medication-taking behaviour questionnaires were administered before the consultation and again 4 weeks after discharge. Developing the preliminary pathway (based on previously established physician communication pathways) involved 2 steps, with investigation of the following associations: (1) between patient-reported effective communication by pharmacists, as per the Communication Accommodation Theory (CAT), and patient satisfaction; and (2) between patient-reported pharmacist communication and satisfaction and patients' medication-taking behaviour. Twelve pharmacists and 48 patients participated. For step 1, almost all patient-reported pharmacist communication behaviours were positively correlated with patient satisfaction statements. Strong associations between CAT-related pharmacist communication behaviours and patient satisfaction highlighted the pharmacists' behaviours that are important to patients and necessary for effective conversations to take place. In step 2, there were fewer correlations of medication-taking behaviour indices with pharmacist communication behaviours and patient satisfaction. This study showed how a preliminary pharmacist communication - patient outcome pathway could be successfully adapted from existing physician communication pathways. Such pathways provide an initial platform upon which future pharmacist communication - patient outcome research can be built.

Attitudes Toward Long-Term Use of Antiretroviral Therapy Among HIV-Infected Pregnant Women in Moshi, Tanzania: A Longitudinal Study.

Adherence to antiretroviral therapy (ART) during pregnancy and the postpartum period is necessary to prevent vertical HIV transmission and to secure the long-term health of an HIV-infected woman. Health behavior theory suggests that patients' attitudes towards medication can predict their medication-taking behaviour. This study sought to understand how women's attitudes towards ART changes between the pregnancy and postpartum periods, and the factors associated with these attitudes. The study enrolled 200 pregnant women living with HIV. Structured surveys were administered during pregnancy and at three and 6months postpartum. Overall, attitudes towards ART were stable over time. More positive attitudes towards ART were associated with HIV acceptance, lower levels of depression, and lower levels of shame. Counselling interventions are needed to help HIV-infected women accept their status and reduce shameful emotions. Depression screening and treatment should be integrated into PMTCT services. This study emphasizes the importance of early attention to attitudes towards ART, in order to establish a trajectory of sustained care engagement.

Exploring stroke survivors' self-efficacy in understanding and taking medication and determining associated factors: a cross-sectional study in a neurology clinic in Malaysia.

Background and aimEvidence-based prescribing practices for stroke-preventive medication have benefited stroke survivors; however, medication-nonadherence rates remain high. Medication understanding and use self-efficacy (MUSE) has shown great importance in medication-taking behavior, but its relationship with medication nonadherence in stroke-preventive regimens lacks exploration. The aim of this study was to determine the prevalence of MUSE and its association with nonadherence causes and other potential factors among stroke survivors in Malaysia.MethodsThis cross-sectional study was conducted among 282 stroke patients who provided informed consent and were in follow-up at the Neurology Outpatient Department of Hospital Kuala Lumpur, Malaysia. The study employed a data-collection form that gathered information on sociodemographics, clinical treatment, outcome measures on MUSE, and medication-nonadherence reasons.ResultsThe prevalence of poor medication understanding and use self-efficacy among stroke patients was 46.5%, of which 29.1% had poor “learning about medication” self-efficacy, while 36.2% lacked self-efficacy in taking medication. Beliefs about medicine (74.02%) was the commonest reason for medication nonadherence, followed by medication-management issues (44.8%). In the multivariate model, independent variables significantly associated with MUSE were health literacy (AOR 0.2, 95% CI 0.069–0.581; P=0.003), medication-management issues (AOR 0.073, 95% CI 0.020-0.266; P<0.001), multiple-medication issues (AOR 0.28, 95% CI 0.085–0.925; P=0.037), beliefs about medicine (AOR 0.131, 95% CI 0.032–0.542; P=0.005), and forgetfulness/convenience issues (AOR 0.173, 95% CI 0.050–0.600; P=0.006).ConclusionThe relatively poor learning about medication and medication-taking self-efficacy in this study was highly associated with health literacy and modifiable behavioral issues related to nonadherence, such as medication management, beliefs about medicine, and forgetfulness/convenience. Further research ought to explore these underlying reasons using vigorous techniques to enhance medication understanding and use self-efficacy among stroke survivors to determine cause–effect relationships.

Survey on medication information literacy and influencing factors among pregnant Chinese women

Background The use of medication during pregnancy is very common. Medication safety has been a great concern among pregnant women and is highly influenced by women’s medication information literacy (MIL). There have been few studies focusing on MIL of pregnant women in China. The misuse of medication during pregnancy may impose on risks on pregnancy. Objectives The focus of this study was to investigate the MIL of pregnant Chinese women and to identify influencing factors. Methods Convenience sampling was used following the distribution of a researcher-designed questionnaire to pregnant women at obstetric clinics. A scale was developed to evaluate participants’ MIL which included medication information needs, medication information sources, medication information quality discrimination, medication information source awareness, and medication-taking behavior. Demographic characteristics of participants, health status and medication use during pregnancy were also collected. Results Questionnaires were completed by 570 participants, yielding a 99% response rate. The total score on the Pregnant Women’s Medication Information Literacy Scale ranged from 47 to 96 with a mean score of 74.25 ± 8.22. A total score of 80% or higher indicated the participants’ have sufficient medication information literacy which was achieved by 28.2% of the sample. Rate of participants who have sufficient MIL on subscale domains were: medication information needs (76.6%), medication-taking behavior (49.9%), medication information source awareness (26.8%), medication information quality discrimination (17.3%) and medication information sources (15.3%). Significant differences were found in the MIL of participants related to education level, location of residence, occupation, household income, age, weeks of gestation and medication history (p < .05). Binary logistic regression analysis indicated that education, income level, location of residence, occupation, and weeks of gestation affected participants’ MIL. Conclusions The overall MIL is low among pregnant Chinese women, which suggests a need for healthcare professionals focusing on medication safety teaching to pregnant women. Interventions by health care professionals in obstetric clinics that promote MIL and prevent adverse events related to medications should be individualized based upon pregnant woman’s education level, financial resources, community of residence, occupation and week of gestation.

Environmental and individual predictors of medication adherence among elderly patients with hypertension and chronic kidney disease: A geospatial approach.

Few studies have examined how adherence to antihypertensive medications varies across different regions or how neighborhood-level factors were related to individuals' medication-taking behaviors in patients. To explore local variation in medication adherence and examine environmental and individual influences on adherence to angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin-receptor blockers (ARBs) among elderly hypertensive patients with chronic kidney disease (CKD) in the United States. The Medicare 5% sample claim data (2006-2013), American Community Survey 5-Year Data (2005-2009) and the Health Resources and Services Administration Primary Care Service Area data (2007). The primary outcome was medication adherence, measured by Proportion of Days Covered (PDC). Geographically weighted regression (GWR) and linear mixed-effects models were used to investigate the relationship between environmental factors, individual risk factors and medication adherence. A total of 70,201 hypertensive CKD patients residing in 2,981 counties of the US were selected. Significant spatial autocorrelation was observed in ACEIs/ARBs PDC. The West North Central and New England regions demonstrated higher adherence compared to the East South Central and West South Central regions. Residing in Medically Underserved Areas, counties with high deprivation scores, and not receiving Part D Low-income Subsidy were associated with poor medication adherence. Medication adherence is geographically differentiated across the US. Environmental and individual factors identified may be helpful in the design of local interventions focused on improving patient outcomes from a population perspective.

Eating and Drinking Recognition in Free-Living Conditions for Triggering Smart Reminders.

The increasingly aging society in developed countries has raised attention to the role of technology in seniors’ lives, namely concerning isolation-related issues. Independent seniors that live alone frequently neglect meals, hydration and proper medication-taking behavior. This work aims at eating and drinking recognition in free-living conditions for triggering smart reminders to autonomously living seniors, keeping system design considerations, namely usability and senior-acceptance criteria, in the loop. To that end, we conceived a new dataset featuring accelerometer and gyroscope wrist data to conduct the experiments. We assessed the performance of a single multi-class classification model when compared against several binary classification models, one for each activity of interest (eating vs. non-eating; drinking vs. non-drinking). Binary classification models performed consistently better for all tested classifiers (k-NN, Naive Bayes, Decision Tree, Multilayer Perceptron, Random Forests, HMM). This evidence supported the proposal of a semi-hierarchical activity recognition algorithm that enabled the implementation of two distinct data stream segmentation techniques, the customization of the classification models of each activity of interest and the establishment of a set of restrictions to apply on top of the classification output, based on daily evidence. An F1-score of 97% was finally attained for the simultaneous recognition of eating and drinking in an all-day acquisition from one young user, and 93% in a test set with 31 h of data from 5 different unseen users, 2 of which were seniors. These results were deemed very promising towards solving the problem of food and fluids intake monitoring with practical systems which shall maximize user-acceptance.

PCV105 EXAMINING THRESHOLDS FOR THE RENIN-ANGIOTENSIN SYSTEM ANTAGONIST MEDICATION ADHERENCE QUALITY MEASURE: THE APPLICATION OF THE LAW OF DIMINISHING RETURNS TO OPTIMIZE ADHERENCE-ASSOCIATED ECONOMIC OUTCOMES

Despite the limited evidence, a threshold of 80% proportion of days covered (PDC) is used to categorize medication adherence. The objective of this study was to assess the association of adherence to renin-angiotensin system antagonist (RASA) medications, defined at deciles of PDC, with disease-specific and all-cause economic outcomes to identify optimal medication adherence thresholds using the law of diminishing returns. This retrospective cohort study included individuals from the Truven Health MarketScan® Commercial Claims and Encounters Research Databases (2010-2012) eligible for inclusion in the Pharmacy Quality Alliance RASA medication adherence measure with non-capitated health plans. Generalized linear models were used to assess the relationship of adherence with economic outcomes (i.e., inpatient utilization and total healthcare costs) while adjusting for covariables (i.e., age, gender, Charlson comorbidity index). Beta coefficients were used to compute utilization and cost ratios and plotted to generate use and cost reduction functions. Marginal use and cost reduction curves were estimated and points of diminishing marginal returns and maximum returns were identified. A total of 1,329,576 individuals were included and most were middle aged (91%), male (54%), and had preferred provider organization insurance (71%). PDC decile-defined adherence definitions of greater than or equal to 45%, 64%, 75%, 83%, 89%, 92%, 95%, 97%, and 99% PDC were assessed. All definitions were associated with lower utilization and costs compared to nonadherence (all p<0.0001). Adherence of 83% and 89% PDC was found to optimize the economic benefits associated with RASA medication-taking behavior. These thresholds were associated with 45.5% to 40.3% lower disease-specific and 53.5% to 54.8% lower all-cause utilization, and 9.1% to 13.6% lower disease-specific and 17.2% to 17.4% lower all-cause expenditures, compared to nonadherence respectively. Adherence between 83% and 89% PDC was found to optimize the economic benefits of RASA medication-taking behavior. Reliance on 80% PDC threshold should be re-evaluated.

Correlates of low-adherence to oral hypoglycemic medications among Hispanic/Latinos of Mexican heritage with Type 2 Diabetes in the United States

AimsWe examined psychosocial- and social/economic factors related to low medication adherence, and sex differences, among 279 adults of Mexican heritage with Type 2 Diabetes. MethodsSelf-report and health record data were used for cross-sectional analyses. Bivariate analyses tested the association of demographic, psychosocial (depression, anxiety, stress) and social/economic factors (insurance type, health literacy, social support) and medication adherence measured by proportion of days covered. Hierarchical regression analyses examined associations between demographic, psychosocial- and social/economic- related factors and low medication adherence stratified by sex. ResultsMore males than females demonstrated low adherence to hypoglycemic medications (75.0.% vs. 70.3%) (p < 0.05). We found significant differences between levels social support and medication adherence (p < 0.05). In hierarchical models, being US born and higher levels of social support were associated with low adherence among males (p < 0.05, and p < 0.001). ConclusionsApproximately 72% of Mexican heritage adults demonstrated low adherence (PDC ≤ 0.50) to their hypoglycemic regimen, and gender differences exist. Interventions should address gender differences in preferences for social support to improve medication-taking behaviors among Mexican heritage males.

Coaching and Education for Diabetes Distress (CEDD): Protocol for a Randomized Controlled Trial.

BackgroundDiabetes distress (DD), a type of psychological distress specific to people with diabetes, is strongly associated with difficulties in performing self-care and inability to meet glycemic targets. Despite increased recognition of the need to manage DD, interventions that are both feasible and effective for reducing DD in routine care settings are not yet known. A pilot study showed that health coaching (HC) has some efficacy in addressing DD, but no adequately powered study has implemented a pragmatic research design capable of assessing the real-world effectiveness of HC in reducing DD.ObjectiveThe aim of this study is to describe the rationale and design of an ongoing clinical trial, Coaching and Education for Diabetes Distress trial, that seeks to assess whether HC effectively reduces DD among primary care patients with diabetes and whether HC is more effective than an educational program targeting DD.MethodsThe 2-arm randomized controlled trial is taking place at an academic family medicine practice in Houston, Texas. Both arms will receive usual care, which includes education about DD. In addition, the intervention arm will receive 8 HC sessions over a 5-month period. The primary outcome measure is reduction in DD over a 6-month period. Additional outcome measures include changes in hemoglobin A1c and self-care practices (medication-taking, dietary, and physical activity behaviors).ResultsAs of March 2019, screening and recruitment are ongoing, and the results are expected by July 2020.ConclusionsHC is feasible in primary care and has been successfully applied to improving chronic disease self-management and outcomes. This study will provide evidence as to whether it has significant value in addressing important unmet psychological and behavioral needs of patients with diabetes.Trial RegistrationClinicalTrials.gov NCT03617146; https://clinicaltrials.gov/ct2/show/NCT03617146 (Archived by WebCite at http://www.webcitation.org/76Va37dbO)International Registered Report Identifier (IRRID)DERR1-10.2196/12166

Temporal effectiveness of interventions to improve medication adherence: A network meta-analysis.

IntroductionAdherence-enhancing interventions have been assessed in the literature, however heterogeneity and conflicting findings have prohibited a consensus on the most effective approach to maintain adherence over time. With the ageing population and growth of chronic conditions, evaluation of sustainable strategies to improve and maintain medication adherence long term is paramount. We aimed to determine the comparative effectiveness of interventions for improving medication adherence over time among adults with any clinical condition.Materials and methodsMeta-analyses evaluating interventions to improve medication adherence were searched in PubMed in January 2019 and reviewed for primary studies. Experimental studies with a comparison group assessing an intervention to enhance medication adherence in adult patients with reported adherence outcomes were included. Two authors extracted data for study characteristics, interventions and adherence outcomes. Interventions were categorized into four groups or combinations: educational, attitudinal, technical and rewards. Four network meta-analyses were performed to compare interventions based on patient follow-up time. Medication adherence effect sizes were reported as odds ratios (OR) with a 95% credibility interval (CrI) and surface under the cumulative ranking curve (SUCRA) to allow ranking probabilities. Risk of bias was assessed as per Cochrane guidelines.ResultsData was obtained from 69 meta-analyses with 468 primary studies being included in qualitative synthesis. The four networks compromised of 249 studies in total (0–3 month follow-up: 99 studies, 4–6 months: 104, 7–9 months: 18, ≥10 months: 94). Interventions showing success in follow-ups of less than 10 months varied across time. Significant effects compared to standard of care (SOC) were found in technical (4–6 months: OR 0.34, 95% CrI 0.25–0.45) and attitudinal interventions (7–9 months: 0.37, 0.17–0.84). Multicomponent interventions demonstrated effectiveness compared to standard of care with an additive effect displayed, particularly in longer follow-ups (educational + attitudinal + technical interventions ≥10 months: OR 0.49, 95% CrI 0.27–0.88).DiscussionAll interventions reviewed improved medication adherence compared to standard of care. Multicomponent interventions displayed the most promising results in maintenance of long-term medication adherence. Technical and reward components enhanced adherence on a short-term basis, while educational and attitudinal interventions evolved over time to be more effective in follow-ups greater than 7 months. Sustainability of adherence to medications over time is dependent upon multicomponent interventions including educational, attitudinal and technical aspects to modify and enhance patient medication-taking behavior. Future research should focus on the most cost-effective approaches able to be integrated into routine practice.

Adherence to treatment in allergic rhinitis using mobile technology. The MASK Study.

Mobile technology may help to better understand the adherence to treatment. MASK-rhinitis (Mobile Airways Sentinel NetworK for allergic rhinitis) is a patient-centred ICT system. A mobile phone app (the Allergy Diary) central to MASK is available in 22 countries. To assess the adherence to treatment in allergic rhinitis patients using the Allergy Diary App. An observational cross-sectional study was carried out on all users who filled in the Allergy Diary from 1 January 2016 to 1 August 2017. Secondary adherence was assessed by using the modified Medication Possession Ratio (MPR) and the Proportion of days covered (PDC) approach. A total of 12143 users were registered. A total of 6949 users reported at least one VAS data recording. Among them, 1887 users reported ≥7 VAS data. About 1195 subjects were included in the analysis of adherence. One hundred and thirty-six (11.28%) users were adherent (MPR ≥70% and PDC ≤1.25), 51 (4.23%) were partly adherent (MPR ≥70% and PDC=1.50) and 176 (14.60%) were switchers. On the other hand, 832 (69.05%) users were non-adherent to medications (MPR <70%). Of those, the largest group was non-adherent to medications and the time interval was increased in 442 (36.68%) users. Adherence to treatment is low. The relative efficacy of continuous vs on-demand treatment for allergic rhinitis symptoms is still a matter of debate. This study shows an approach for measuring retrospective adherence based on a mobile app. This also represents a novel approach for analysing medication-taking behaviour in a real-world setting.

Medication-Taking Behaviors and Perceptions Among Adults With Heart Failure (from the REasons for Geographic And Racial Differences in Stroke Study)

Medication regimens in adults with heart failure (HF) are complex which can complicate patient adherence. Individuals with HF frequently use beta blockers (BBs) for multiple indications, including hypertension and HF, but BBs can have significant side effects that may affect their use. We examined medication-taking behaviors and perceptions in individuals with HF with a particular focus on BBs. A mailed survey on medication use was administered to US adults with HF enrolled in the REasons for Geographic And Racial Differences in Stroke study. Among 518 respondents, 357 (69%) reported taking a BB. Nearly half (42%) reported taking ≥10 medications per day. However, 45% indicated that they did not miss any days taking medications, and over 85% reported willingness to take additional medications to prevent further healthcare encounters. Participants' perceptions of BB symptoms varied, but 56% of those who reported experiencing symptoms did not discuss this with their healthcare providers. Adults who experienced HF hospitalization had higher odds of reporting taking BBs to treat HF (odds ratio 1.51, 95% confidence interval 1.19, 1.91). Adults with hypertension were also likely to report taking BBs to treat high blood pressure (odds ratio 2.42, 95% confidence interval 1.79, 3.26). In conclusion, despite extensive medication regimens, individuals with HF were willing to take additional medications for their disease. Participant recognition of BB use for treating HF and co-morbidities was high, yet many do not report side effects to healthcare providers. In conclusion, better understanding of patients' medication-taking behaviors and perceptions may facilitate optimization of HF treatments.

Conceptualisation of medication beliefs among patients with advanced cancer receiving oral oncolytic agents using a theory derivation approach.

This paper describes a derived model that provides a conceptual framework for understanding medication beliefs among patients with advanced cancer receiving oral oncolytic agents. Theory derivation was used to (a) examine the phenomenon of medication beliefs in cross-disciplinary research; (b) select a parent theory for derivation; (c) identify parent theory concepts and/or structure to use in derivation; and (d) redefine parent theory concepts and structure to create a derived model. Medication beliefs are shaped by previous experiences, including cognitive and emotional factors, past health and illness encounters, and medication-taking behaviours. Medication beliefs are defined within a larger mental model of illness representation for which medication was prescribed. Individuals independently hold both positive and negative medication beliefs at the same time. This distinction is critical to understanding how dichotomous components of medication beliefs change over time as they are influenced by varying treatment-related factors. This paper contributes to conceptual knowledge regarding the phenomenon of medication beliefs and their impact on health behaviour. Findings can support oncology interventions to improve patient outcomes including medication adherence.

The impact of non-medical switching among ambulatory patients: an updated systematic literature review

ABSTRACTBackground: Non-medical switching (NMS) is defined as switching to a clinically similar but chemically distinct medication for reasons apart from lack of effectiveness, tolerability or adherence.Objective: To update a prior systematic review evaluating the impact of NMS on outcomes.Data sources: An updated search through 10/1/2018 in Medline and Web of Science was performed.Study selection: We included studies evaluating ≥25 patients and measuring the impact of NMS of drugs on ≥1 endpoint.Data extraction: The direction of association between NMS and endpoints was classified as negative, positive or neutral.Data synthesis: Thirty-eight studies contributed 154 endpoints. The direction of association was negative (n = 48; 31.2%) or neutral (n = 91; 59.1%) more often than it was positive (n = 15; 9.7%). Stratified by endpoint type, NMS was associated with a negative impact on clinical, economic, health-care utilization and medication-taking behavior in 26.9%,41.7%,30.3% and 75.0% of cases; with a positive effect seen in 3.0% (resource utilization) to 14.0% (clinical) of endpoints. Of the 92 endpoints from studies performed by the entity dictating the NMS, 88.0%were neutral or positive; whereas, only 40.3%of endpoints from studies conducted separately from the interested entity were neutral or positive.Conclusions: NMS was commonly associated with negative or neutral endpoints and was seldom associated with positive ones.

Effect of patient education on medication adherence of patients with rheumatoid arthritis: a randomized controlled trial.

PurposeThere is a general understanding that patient educational interventions for enhancing medication adherence are important. However, their success at improving adherence is debatable. This study aimed to assess the influence of different modes of patient education on medication adherence in patients with rheumatoid arthritis (RA).Materials and methodsOne hundred and twenty RA patients with non-adherence, defined as pill count ≥80% or medication-taking behavior questionnaire for Thai patient ≥23, were randomized by block randomization and assigned in a 1:1 allocation ratio to two study arms: multi-component intervention group or single intervention group. The multi-component intervention group received 30-minute directed counseling and a disease information pamphlet. The single intervention group received only a disease information pamphlet. The primary outcomes were an improvement in an adherence rate measured by pill count after 12 weeks. The Thai Clinical Trial Registry number is TCTR20171207003.ResultsAfter 12 weeks, the pill count adherence rate increased significantly from baseline in both study groups. In the multi-component intervention group, adherence rate increased from 92.21±14.05 to 97.59±10.07 (P=0.002) and in the single intervention group, it increased from 88.60±19.66 to 92.42±14.27 (P=0.044). However, the mean difference between the multi-component intervention group and the single intervention group was not significant (5.38±12.90 vs 3.18±14.23, P=0.531). Clinical outcomes, including disease activity score 28, EuroQoL-5D, EuroQol visual analog scale, pain score, and physician global assessment were unchanged from baseline in both groups.ConclusionPatient education significantly improved adherence. However, there were no differences between single education intervention and multi-component education intervention in improving medication adherence. Provision of a disease information pamphlet with or without directed counseling can equally enhance medication adherence of patients with RA.

Cross-sectional survey study to examine underuse of twice daily inhaled maintenance therapy among patients with asthma

Objective: Anecdotal evidence suggests that some patients with asthma intentionally use their twice-daily (BID) inhaled controller therapy once daily (QD), thus not achieving optimal dosing levels. This study identified the prevalence of and factors associated with intentional QD use of BID-indicated controllers among adult patients with asthma. Methods: This was a cross-sectional survey study of adults using inhaled controllers intended for BID dosing for treatment of asthma and/or COPD. Survey responses were linked to administrative claims data for the prior 12 months (baseline). Results of patients indicating both an asthma diagnosis and current intentional QD or BID use of controllers are presented. Results: Of 1401 patients with asthma, 30.9% reported intentional QD use of their controller and 69.1% reported BID use. Intentional QD use was mostly a function of patients’ lack of perceived need for BID treatment (44.1%) or physician orders to take their controller QD (34.0%). Patients reporting intentional QD use tended to be healthier (higher health status scores, and lower Charlson comorbidity scores, ambulatory and ER visits, and healthcare costs) with better asthma control (lower asthma-related ER and ambulatory visits and rescue medication use, and higher Asthma Control Test scores) compared with patients reporting BID use. Conclusions: Perceptions regarding health and the necessity of controller use to control or treat asthma were the main drivers of medication-taking behavior. Patients with less severe asthma were more likely to report once daily use of their inhaled controller, but still maintained asthma control.

Adherence to chronic medication in older populations: application of a common protocol among three European cohorts.

PurposeThe purpose of this study was to evaluate and compare medication adherence to chronic therapies in older populations across different regions in Europe.MethodsThis explorative study applied a harmonized method of data extraction and analysis from pharmacy claims databases of three European countries to compare medication adherence at a cross-country level. Data were obtained for the period between January 1, 2010, and December 31, 2011. Patients (aged ≥65 years) who newly initiated to oral antidiabetics, antihyperlipidemics, or antiosteoporotics were identified and followed for over a 12-month period. Main outcome measures were medication adherence (medication possession ratio, [MPR]; implementation) and persistence on index treatment. All country-specific data sets were prepared by employing a common data input model. Outcome measures were calculated for each country and pooled using random effect models.ResultsIn total, 39,186 new users were analyzed. In pooled data from the three countries, suboptimal implementation (MPR <80%) was 52.45% (95% CI: 33.43–70.79) for antihy-perlipidemics, 61.35% (95% CI: 52.83–69.22) for antiosteoporotics, and 30.33% (95% CI: 25.53–35.60) for oral antidiabetics. Similarly, rates of non-persistence (discontinuation) were 55.63% (95% CI: 35.24–74.29) for antihyperlipidemics, 60.24% (95% CI: 45.35–73.46) for antiosteoporotics, and 46.80% (95% CI: 36.40–57.4) for oral antidiabetics.ConclusionMedication adherence was suboptimal with >50% of older people non-adherent to antihyperlipidemics and antiosteoporotics in the three European cohorts.
