Impact of prescription length supply policy on patient medication adherence in Thailand

BACKGROUND

Phramongkutklao Hospital is one of the largest military hospitals in Thailand. Beginning in 2016, an institutional policy was implemented in which medication prescription length was increased from 30 to 90 days. However, there have been no formal investigations into how this policy has impacted medication adherence among patients in hospitals. As such, this study evaluated how prescription length impacted medication adherence among dyslipidemia and type-2 diabetes patients who were treated at Phramongkutklao Hospital.

METHODS

This pre-post implementation study compared patients who received prescription lengths of 30 and 90 days based on information recorded in the hospital database between 2014 and 2017. Therein, we used the medication possession ratio (MPR) to estimate patient adherence. Focusing on patients with universal coverage insurance, we employed the difference-in-difference method to examine changes in adherence from before and after policy implementation, then conducted a logistic regression to test for associations between the predictors and adherence.

RESULTS

We analyzed data from a total of 2,046 patients, with equal amounts of 1,023 placed into the control group (no change to 90-day prescription length) and intervention group (change from 30 to 90-day prescription length). First, we found that increased prescription length was associated with 4% and 5% higher MPRs among dyslipidemia and diabetes patients in the intervention group, respectively. Second, we found that medication adherence was correlated with sex, comorbidities, history of hospitalization, and the number of prescribed medications.

CONCLUSION

Increasing the prescription length from 30 to 90 days improved medication adherence in both the dyslipidemia and type-2 diabetes patients. This shows that the policy change was successful for patients in the hospital considered for this study.

Exploring Validated Self-Reported Instruments to Assess Adherence to Medications Used: A Review Comparing Existing Instruments

OBJECTIVE

To provide an overview of instruments that measure adherence to medications to facilitate selection of an instrument and to provide a summary of some published adherence assessment tools tailored to be used by the healthcare team, especially the pharmacists.

DATA SOURCES

Studies were identified via PubMed, Medline, Embase, and Google Scholar using the search terms medication adherence, compliance, persistence, combined with the terms questionnaire, scale, survey, self-report, and instrument.

STUDY SELECTION

Articles written in English, describing questionnaire instruments that were psychometrically evaluated (reporting a good coefficient of internal consistency, reliability assessed through Cronbach's alpha, and had been validated against a subjective or objective measure), and containing 30 or fewer items were included.

DATA SYNTHESIS

Twelve instruments were identified and included in this review. Instruments were reviewed by evaluating specific characteristics (number of items, sample size, reliability, sensitivity, specificity, questionnaire completion time, criterion validity, and component analysis).

CONCLUSION

Various instruments are used to assess patient adherence to medications; however, no single one performs well on all criteria. Every instrument has different advantages and unique properties. A particular instrument can be chosen after considering certain factors, such as the specific requirements, population, the needed time to complete the questionnaire, the sensitivity, and the specificity of the questionnaire. Moreover, there is a recognized need to provide primary care medication adherence services customized to patient's needs. A link for teamwork between healthcare providers such as pharmacists and patients is needed. This link can be a validated instrument to assess patient's adherence to medication.

"Without my medication, I'm a wreck": Photo-elicitation to explore medication use among people experiencing homelessness

BACKGROUND

People experiencing homelessness (PEH) live with a high burden of chronic illness, functional and cognitive impairments, and serious mental illness. Many PEH are prescribed complex medication regimens to manage symptoms and improve health and functioning. However, medication use within the context of homelessness is complicated, and adherence is often suboptimal.

OBJECTIVE

To document medication use within the context of homelessness and explore experiences of medication use among people experiencing homelessness (PEH).

METHODS

This study used mixed methods including photo-elicitation interviews. Participants were given a digital camera and asked to take pictures of people, places, things, and situations that represented every day medication use. Participants were also asked to write down reasons for taking the pictures. After two weeks, participants returned the camera and notes. At a subsequent interview, the photographs and notes were reviewed and discussed. Demographic and health-related information was also collected for each participant. An interpretive description approach was used for qualitative data analysis. Quantitative data were analyzed using descriptive statistics in order to describe the sample.

RESULTS

Seven PEH completed this study. Mean age was 45 years (SD = 11.3) and length of homelessness was 6.1 years (SD = 11.3). All reported multiple chronic conditions (≥2) and reported taking 6.6 (SD = 2.6) medications. Participants reported medication adherence barriers with mean score of 37 (SD = 5.5) on the ASK-12, a 12-item scale with a range of 12-60 (higher scores indicate more barriers). Qualitative analysis identified four categories: medication-related burdens, medication-related beliefs, connectedness, and stigmatizing encounters.

CONCLUSIONS

Medication use among PEH is complex and cannot be considered separately from daily life or from struggles to meet basic needs. Multi-level interventions are needed to optimize medication use among PEH, and healthcare professionals including community pharmacists should reinforce beliefs that medication-related benefits outweigh the burdens and then tailor services to the context of homelessness.

Real-world adherence to, and persistence with, once- and twice-daily oral disease-modifying drugs in patients with multiple sclerosis: a systematic review and meta-analysis

BACKGROUND

Nonadherence to disease-modifying drugs (DMDs) for multiple sclerosis (MS) is associated with poorer clinical outcomes, including higher rates of relapse and disease progression, and higher medical resource use. A systematic review and quantification of adherence and persistence with oral DMDs would help clarify the extent of nonadherence and nonpersistence in patients with MS to help prescribers make informed treatment plans and optimize patient care. The objectives were to: 1) conduct a systematic literature review to assess the availability and variability of oral DMD adherence and/or persistence rates across 'real-world' data sources; and 2) conduct meta-analyses of the rates of adherence and persistence for once- and twice-daily oral DMDs in patients with MS using real-world data.

METHODS

A systematic review of studies published between January 2010 and April 2018 in the PubMed database was performed. Only studies assessing once- and twice-daily oral DMDs were available for inclusion in the analysis. Study quality was evaluated using a modified version of the Newcastle-Ottawa Scale, a tool for assessing quality of observational studies. The random effects model evaluated pooled summary estimates of nonadherence.

RESULTS

From 510 abstracts, 31 studies comprising 16,398 patients with MS treated with daily oral DMDs were included. Overall 1-year mean medication possession ratio (MPR; n = 4 studies) was 83.3% (95% confidence interval [CI] 74.5-92.1%) and proportion of days covered (PDC; n = 4 studies) was 76.5% (95% CI 72.0-81.1%). Pooled 1-year MPR ≥80% adherence (n = 6) was 78.5% (95% CI 63.5-88.5%) and PDC ≥80% (n = 5 studies) was 71.8% (95% CI 59.1-81.9%). Pooled 1-year discontinuation (n = 20) was 25.4% (95% CI 21.6-29.7%).

CONCLUSIONS

Approximately one in five patients with MS do not adhere to, and one in four discontinue, daily oral DMDs before 1 year. Opportunities to improve adherence and ultimately patient outcomes, such as patient education, medication support/reminders, simplified dosing regimens, and reducing administration or monitoring requirements, remain. Implementation of efforts to improve adherence are essential to improving care of patients with MS.

Simulated medication adherence: First and second-year pharmacy students' perceptions of adhering to a multi-drug medication regimen

BACKGROUND AND PURPOSE

Through a realistic medication adherence activity, the objective was to improve students' ability to identify non-adherent patients, build empathy toward patients, and prepare them to provide patient-centered care.

EDUCATIONAL ACTIVITY AND SETTING

First- and second-year student pharmacists completed a two-month activity, which required adherence to a pre-specified medication regimen. Prior to starting, a survey was administered to assess students' perceived difficulty and success of the medication adherence activity. Upon completion, students were asked their perceived success and difficulty with the activity, challenges to maintaining adherence, and lessons learned from the project. Changes in perceived difficulty and success were analyzed using Wilcoxon signed rank tests. Challenges and lessons learned were coded for similar themes and frequencies.

FINDINGS

298 student pharmacists completed the pre- and post-survey (response rate 99%). Students' perceived difficulty of adherence was higher on the post-survey (median on post = 7.0 (out of 10) versus median on pre = 6.0, p = 0.023). Students' perceived success was higher on the presurvey (median on pre = 8.0 versus median on post = 6.0, p < 0.001). The most frequent challenges were remembering to take the medications (n = 133) and medication regimen timing (n = 98). The most frequent lesson learned was that "adherence is a difficult concept" (n = 143).

SUMMARY

Students participated in a "hands-on" medication adherence activity. Students found that medication adherence is more difficult than perceived. Future research should examine the long-term impact of students maintaining empathy toward patients and provision of medication adherence services.

Mobile Phone Text Messages and Effect on Treatment Adherence in Patients Taking Methotrexate for Rheumatoid Arthritis: A Randomized Pilot Study

OBJECTIVE

To assess the impact of weekly text messages on adherence in patients taking methotrexate (MTX) for rheumatoid arthritis (RA).

METHODS

This prospective, randomized pilot, single-site study included patients with RA stabilized using MTX alone or combined with biologics. Participants were randomized to 3 interventions: a standard consultation (controls), a 15-minute pharmacist-led counseling session, or the receipt of text message reminders. The change over time in the Compliance Questionnaire Rheumatology (CQR-19) score between baseline and 6 months was defined as the primary outcome for adherence. Multivariable analyses and final adherence (as a composite outcome of the CQR-19 score, the Girerd score, and the medication possession ratio) were probed in sensitivity tests. Rheumatologic scales, inflammation, and patient satisfaction were also analyzed.

RESULTS

A total of 96 patients (mean ± SD Disease Activity Score in 28 joints 2.42 ± 1.03) were monitored. The change over time in the CQR-19 score was significantly higher in the text message group (mean ± SD 3.32 ± 5.66; P = 0.02) than in the control group (mean ± SD 0.22 ± 6.56) and the pharmacist-led counseling group (mean ± SD -0.14 ± 7.56). Multivariable logistic regression showed that text messages remained associated with an increase in the CQR-19 score, independently of the baseline CQR-19 score (odds ratio 3.63 [95% confidence interval 1.26-10.49]; P = 0.017). In the text message group, the increase in the CQR-19 score was correlated with the Health Assessment Questionnaire score (r = -0.405, P = 0.021), and patient satisfaction was significantly higher (P < 0.01) than in the control group.

CONCLUSION

Our results showed evidence of a positive impact of text messages on adherence to MTX treatment for RA. The clinical benefit and the ideal target patient remain to be determined.

Compliance and Adherence to Enteral Nutrition Treatment in Adults: A Systematic Review

Objective: To review the scientific literature that has verified and/or assessed compliance and adherence to enteral nutrition (EN) in adult patients. Method: This study involved a critical analysis of articles retrieved from MEDLINE (PubMed), The Cochrane Library, Embase, Scopus and Web of Science using the terms “Treatment Adherence and Compliance” and “Enteral Nutrition”, applying the filters “Comparative Study” or “Clinical Trial”, “Humans” and “Adults”. Date of the search: 25 October 2018. Results: A total of 512 references were retrieved, of which 23 documents were selected after applying the inclusion and exclusion criteria. The techniques measuring adherence to EN were determined by dietary intake, self-reporting, counts of leftover containers or presence of complications; however, in no case were validated questionnaires used. The time and periodicity of the assessment presented very heterogeneous results, with measurement predominantly being done at the beginning and at the end of the study. The best adherence rates were obtained in hospitalized patients (approximately 80%). Conclusions: Frequent and regular monitoring of the adherence of patients under prolonged treatment with EN is necessary, and the use of measurement techniques that allow obtaining information on the causes of non-adherence facilitates early interventions to optimize treatment outcomes. Patient and/or caregiver education in the management of EN and the intervention of the community pharmacy in monitoring patients can be key to improving the adherence to EN.

The Need to Strengthen the Role of the Pharmacist in Sri Lanka: Perspectives

The role of the pharmacist in healthcare has evolved greatly over the last half-century, from dispensing to providing direct patient-oriented activities not associated with dispensing. However, pharmacist-led healthcare services in Sri Lanka must undergo reform to fully take advantage of their expertise and training in medicine management and related outcomes in Sri Lankan patients. As befits a profession's role development and value, professional and educational standards for pharmacists need ongoing development and growth. Currently, university curricula and continuing professional education in Sri Lanka require further development and optimisation to provide the theoretical and practical knowledge and skills regarding quality use of medicines and patient-oriented care. Furthermore, pharmacists' roles in Sri Lankan hospital and community pharmacist settings need to be recognised and should include the pharmacist as an integral part of the multidisciplinary healthcare team in Sri Lanka. Studies from developed countries and some developing countries have demonstrated that expanded pharmacists' roles have had a significant positive cost-effective impact on the population's health. Therefore, the availability of qualified Sri Lankan pharmacists trained to deliver expanded professional services accompanied by greater pharmacist integration into healthcare delivery is crucially important to ensure quality use of medicines within the Sri Lankan healthcare system and optimise the medication-related needs of Sri Lankans.

Medication Simulation Affects Health Provider Students' Attitudes About Adherence and Concordance

INTRODUCTION

Assisting polypharmacy patients with complex health regimens is a part of health provider responsibilities. The concepts of adherence and concordance contrast the traditional emphasis on patient compliance. However, health provider students may not be able to empathize with polypharmacy patients. The purpose of this study was to measure the effect of a medication simulation on medical, nursing, and pharmacy students' beliefs about adherence and concordance.

METHODS

A prospective, quasi-experimental, pretest, and posttest design was used with institutional review board approval. The participants (N = 62) took four simulated medications (varied dosing schedules) for 1 week. Attitudes toward adherence and concordance were assessed before and after the intervention.

RESULTS

Subjects averaged 24.6 years (SD = 4.32), 72.6% female, and 79% white. Most were medical students (n = 33, 53%), followed by nursing (n = 21, 34%) and pharmacy students (n = 8, 13%). There were significant changes [t(61) = 3.92, P < 0.001] in beliefs about adherence from time 1 (mean = 25.13, SD = 5.77) to time 2 (mean = 22.05, SD = 6.06), and about concordance (mean = 41.85, SD = 5.58 time 1) to (mean = 44.29, SD = 6.32 time 2) [t(61) = 3.31, P < 0.05], for the entire group. Most students (84%) predicted that they would be able to take four medications correctly for 1 week. Fifty-eight students (94%) found that adherence was 'much harder' or 'a little harder' than anticipated. Most (89%) felt that the simulation will impact their patient care.

CONCLUSIONS

Participation in a medication simulation exercise affected health provider students' attitudes toward adherence and concordant behaviors. These experiences may influence future patient interactions.

Situational communication self-confidence among community pharmacists: A descriptive analysis

Objective:

To compare community pharmacists’ self-perceived communication confidence in prescription drug abuse and addiction (PDAA)-related scenarios to their self-confidence in other scenarios.

Methods:

An 18-item survey instrument adapted from the Self-Perceived Communication Competence instrument was administered to 2000 licensed Tennessee community pharmacists. Items elicited communication confidence across common community pharmacy scenarios. Analysis of communication self-confidence scores across context, receiver, audience, and demographic variables was conducted.

Results:

Mean self-confidence ratings ranged from 54.2 to 92.6 (0–100 scale). Self-perceived communication confidence varied across context, receiver, audience, personal and practice setting characteristics. Scenarios that involved PDAA communication with patients were scored significantly lower than non-PDAA patient scenarios (mean = 84.2 vs. 90.4, p<0.001).

Conclusion:

Community pharmacists are less confident in their ability to communicate with patients about PDAA as compared to non-PDAA scenarios.

Practice Implications:

Engaging patients and prescribers in PDAA conversations is a critical component of preventing and treating PDAA. Research is warranted to further explore measures of situational communication self-confidence and interventions to optimize self-confidence beliefs across PDAA scenarios.

Putting words into action: A simple focused education improves prescription label comprehension and functional health literacy

OBJECTIVES

To assess the effectiveness of an educational intervention on prescription (Rx) label comprehension and functional health literacy (FHL) in older adults. Outcomes were compared between current and redesigned Rx labels. Additional objectives were to examine the correlation between 2 outcome measures and to determine the characterizing variables that are predictors for the outcome measures.

SETTING

Southern California, January 2013 to March 2015.

PRACTICE DESCRIPTION

Older adults (>55 y) taking 2 or more Rx medications daily were recruited at senior and community centers by a trained data collection team.

PRACTICE INNOVATION

The validated Modified LaRue Tool (MLT) tested Rx label comprehension before and after a short, focused educational intervention and correlated it with FHL.

INTERVENTIONS

A simple one-on-one education provided by student pharmacists that was focused on critical elements of an Rx label.

EVALUATION

Short Test of Functional Health Literacy in Adults (STOFHLA) and MLT scores of all current and redesigned label participants at baseline and follow-up.

RESULTS

Participants using redesigned Rx labels (n = 90) showed significantly higher MLT scores than with current Rx labels (n = 28) both before (23.0 ± 2.3 vs. 21.0 ± 2.4; P <0.001) and after educational intervention (23.8 ± 1.7 vs. 22.1 ± 3.1; P <0.001). With the use of analysis of covariance, intervention participants using redesigned label (n = 48) showed significant improvement in both MLT (23.1 ± 2.0 to 24.3 ± 1.0; P <0.001) and STOFHLA (29.8 ± 7.5 to 31.5 ± 5.7; P = 0.011) scores, whereas intervention participants using current Rx label (n = 16) did not show significant improvement in either MLT (P = 0.530) or STOFHLA (P = 0.215) scores. Effect size of intervention (redesigned label) was 0.77, indicating practical significance. MLT and STOFHLA scores were significantly correlated with each other, and age and education level were common significant predictors for both outcomes.

CONCLUSION

Older adults using redesigned Rx labels showed improved Rx label comprehension and FHL after educational intervention, as well as higher comprehension compared with those using current Rx labels. Use of a redesigned Rx label and a simple educational intervention should be encouraged to improve Rx label comprehension and FHL.

The role of community pharmacy-based vaccination in the USA: current practice and future directions

Community pharmacy-based provision of immunizations in the USA has become commonplace in the last few decades, with success in increasing rates of immunizations. Community pharmacy-based vaccination services are provided by pharmacists educated in the practice of immunization delivery and provide a convenient and accessible option for receiving immunizations. The pharmacist’s role in immunization practice has been described as serving in the roles of educator, facilitator, and immunizer. With a majority of pharmacist-provided vaccinations occurring in the community pharmacy setting, there are many examples of community pharmacists serving in these immunization roles with successful outcomes. Different community pharmacies employ a number of different models and workflow practices that usually consist of a year-round in-house service staffed by their own immunizing pharmacist. Challenges that currently exist in this setting are variability in scopes of immunization practice for pharmacists across states, inconsistent reimbursement mechanisms, and barriers in technology. Many of these challenges can be alleviated by continual education; working with legislators, state boards of pharmacy, stakeholders, and payers to standardize laws; and reimbursement design. Other challenges that may need to be addressed are improvements in communication and continuity of care between community pharmacists and the patient centered medical home.

Medication adherence challenges among patients experiencing homelessness in a behavioral health clinic

BACKGROUND

Behavioral health medication nonadherence is associated with poor health outcomes and increased healthcare costs. Little is known about reasons for nonadherence with behavioral health medications among homeless people.

OBJECTIVES

To identify reasons for medication nonadherence including the sociodemographic, health-related factors, and behavioral health conditions associated with medication nonadherence among behavioral health patients served by a Health Care for the Homeless center (HCH) in Virginia.

METHODS

The study sample was selected from an existing database that included sociodemographic, health-related information, and medication-related problems identified during a pharmacist-provided medication review conducted during October 2008-September 2009. Patients experiencing or at risk of homelessness who were ≥18 years old with at least one behavioral health condition who had a medication review were eligible for the study. A qualitative content analysis of the pharmacist documentation describing the patient's reason(s) for medication nonadherence was conducted. The Behavioral Model for Vulnerable Populations was the theoretical framework. The outcome variable was self-reported medication nonadherence. Descriptive and multivariate (logistic regression) statistics were used.

RESULTS

A total of 426 individuals met study criteria. The mean age was 44.7 ± 10.2 years. Most patients were African-American (60.5%) and female (51.6%). The content analysis identified patient-related factors (74.8%), therapy-related factors (11.8%), and social or economic factors (8.8%) as the most common reasons for patients' medication nonadherence. Patients with post-traumatic stress disorder (PTSD) (adjusted odds ratio: 0.4; 95% CI: 0.19-0.87) were less likely to have a medication adherence problem identified during the medication review.

CONCLUSIONS

The content analysis identified patient-related factors as the most common reason for nonadherence with behavioral health medications. In the quantitative analysis, patients with a PTSD diagnosis were less likely to have nonadherence identified which may be related to their reluctance to self-report nonadherence and their diagnosis, which warrants further study.

3Ps--Pharmacist, Physician and Patient: Proposal for Joint Cooperation to Increase Adherence to Medication

OBJECTIVE

Older people receive medications for chronic diseases and therefore adherence is an important health and economic concern. The objective of the study is to determine relationships between pharmacist, patient and patient's family physician with special emphasis on the comparison of adherent and non-adherent patients.

METHODS

The study was designed as a cross-sectional survey by use of a self-administered 33-item questionnaire. The study included 635 individuals collecting or buying drugs for the treatment of chronic diseases and 84 pharmacists dispensing drugs for chronic diseases to patients.

RESULTS

The study included 265 (41.7%) adherent and 370 (58.3%) non-adherent patients. Comparison of particular answers between patients and pharmacists revealed a discrepancy, with a significant difference in five of eight answers. The highest difference was recorded in answers to the question whether a pharmacist offered thorough advice to the patient on how to take the drug; an affirmative answer to this question was given by 90.5% of pharmacists and only 57.2% of patients. The analysis of respondents' claims about their relation with one doctor shows that in the first place, with the highest number of positive responses, is the claim of the respondents that their doctor always explains the results of laboratory tests and other specialized findings (n = 489, 77.0%).

CONCLUSION

Enhancing communication between the physician, the pharmacist and the patient is a key in boosting the patient's ability to follow a medication regimen. Pharmacist-physician-patient relationship can improve adherence to medication. It is very important to empower pharmacists to offer and allow time for patient counselling.

Evaluating the Potential Impact of Pharmacist Counseling on Medication Adherence Using a Simulation Activity

OBJECTIVE

To evaluate the impact of counseling in a simulated medication adherence activity.

DESIGN

Students were randomized into 2 groups: patient medication monograph only (PMMO) and patient medication monograph with counseling (PMMC). Both groups received a fictitious medication and monograph. Additionally, the PMMC group received brief counseling. A multiple-choice, paper-based survey instrument was used to evaluate simulated food-drug interactions, adherence, and perceptions regarding the activity's value and impact on understanding adherence challenges.

ASSESSMENT

Ninety-two students participated (PMMC, n=45; and PMMO, n=47). Overall, a significantly higher incidence of simulated food-drug interactions occurred in the PMMO group (30%) vs the PMMC group (22%) (p=0.02). Doses taken without simulated food-drug interactions were comparable: 46.2% (PMCC) vs 41.9% (PMMO) (p=0.19). The average number of missed doses were 3.2 (PMMC) vs 2.8 (PMMO) (p=0.55). Approximately 70% of the students found the activity to be valuable and 89% believed it helped them better understand adherence challenges.

CONCLUSION

This activity demonstrated the challenges and important role of counseling in medication adherence.

Medication adherence behaviors of Medicare beneficiaries

BACKGROUND

Medication adherence is crucial for positive outcomes in the management of chronic conditions. Comprehensive medication consultation can improve medication adherence by addressing intentional and unintentional nonadherence. The Medicare Part D prescription drug benefit has eliminated some cost barriers. We sought to examine variables that impact self-reported medication adherence behaviors in an ambulatory Medicare-beneficiary population and to identify the factors that influence what information is provided during a pharmacist consultation.

METHODS

Medicare beneficiaries who attended health fairs in northern California were offered medication therapy management (MTM) services during which demographic, social, and health information, and responses to survey questions regarding adherence were collected. Beneficiaries were also asked which critical elements of a consultation were typically provided by their community pharmacist. Survey responses were examined as a function of demographic, socioeconomic, and health-related factors.

RESULTS

Of the 586 beneficiaries who were provided MTM services, 575 (98%) completed the adherence questions. Of responders, 406 (70%) reported taking medications "all of the time". Of the remaining 169 (30%), the following reasons for nonadherence were provided: 123 (73%) forgetfulness; 18 (11%) side effects; and 17 (10%) the medication was not needed. Lower adherence rates were associated with difficulty paying for medication, presence of a medication-related problem, and certain symptomatic chronic conditions. Of the 532 who completed survey questions regarding the content of a typical pharmacist consultation, the topics included: 378 (71%) medication name and indication; 361 (68%) administration instructions; 307 (58%) side effects; 257 (48%) missed-dose instructions; and 245 (46%) interactions. Subsidy recipients and non-English speakers were significantly less likely to be counseled on drug name, indication, and side effects. The presence of certain health conditions was also associated with missing consultation elements.

CONCLUSION

While Medicare beneficiaries are generally adherent to medication therapy, adherence barriers must be identified and addressed during comprehensive medication consultation.

Predictors and impact of non-adherence in adults with attention-deficit/hyperactivity disorder receiving OROS methylphenidate: results from a randomized, placebo-controlled trial

BACKGROUND

Medication non-adherence has an important impact on treatment efficacy and healthcare burden across a range of conditions and therapeutic areas. The aim of this analysis was to determine predictors of non-adherence and impact of non-adherence on treatment response in adults with attention-deficit/hyperactivity disorder (ADHD).

METHODS

Post-hoc analysis of a 13-week randomized, double-blind placebo-controlled study of OROS methylphenidate (MPH) 54 and 72 mg/day. Primary efficacy variable was the Conners' Adult ADHD Rating Scale - Screening Version (CAARS:O-SV). Daily adherence was calculated as average daily adherence (100 × capsules taken/2), with overall adherence calculated as the average daily adherence. Predictors of adherence were assessed using mixed-effects logistic regression. Descriptive statistics were generated for change in CAARS:O-SV score for adherent (> 95% adherence) and non-adherent subjects. Predictors of change were analyzed using a mixed model.

RESULTS

Subjects were allocated to OROS MPH (54 mg, n = 87; 72 mg, n = 92) or placebo (n = 97). Mean adherence was 92.6% and 93.3% (OROS MPH 54 and 72 mg/day, respectively), versus 97.5% (placebo). Adherence was higher and less variable in completers. Factors significantly associated with non-adherence included female sex, shorter time since ADHD diagnosis, higher education level (completion of university) and score on the Drug Use Screening Inventory psychiatric disorders subscale. Improvements from baseline in CAARS:O-SV score were numerically greater in subjects defined as adherent than in those who were non-adherent. Significant predictors of CAARS:O-SV change in patients who completed the study included percentage adherence up to the point of assessment (p < 0.0001), baseline score (p < 0.0001) and family history of ADHD (p = 0.0003).

CONCLUSION

The results of this analysis suggest that newly diagnosed patients, those with a high score on the DUSI-R psychiatric disorder scale, women, and subjects with high educational degrees may be at increased risk of non-adherence. Clinicians and policymakers should therefore pay special attention to these individuals, as non-adherence is a significant predictor of reduced response to treatment.

Facilitating medication adherence in patients with multiple sclerosis

This article reviews adherence to medication in multiple sclerosis (MS) patients from the perspective of nurse and social worker authors. It reviews data on patient adherence and offers practical, evidence-based strategies that health-care providers can use to facilitate adherence. In addition, it examines how emerging MS therapies may affect patient adherence and associated interventions. To promote adherence, interventions need to incorporate new and creative approaches. A proactive approach includes assessing patient needs and lifestyle before the start of medication and selecting the most appropriate disease-modifying therapy for each individual patient. Including multidisciplinary expertise and services in the treatment plan can be part of a comprehensive, holistic approach to helping patients and families. Optimization of health-care provider roles is likely to facilitate improved adherence.

Fatores associados à adesão ao tratamento de pacientes com diabetes mellitus

OBJETIVO: Investigar associação entre adesão ao tratamento do diabetes mellitus tipo 2 e variáveis sociodemográficas, clínicas e controle metabólico. MÉTODOS: Desenho cross seccional com 423 portadores de diabetes mellitus. Para verificar a associação entre adesão ao tratamento e as variáveis estudadas, utilizou-se teste exato de Fisher e modelos de regressão logística. RESULTADOS: Não houve associação entre adesão ao tratamento do DM2 e variáveis sociodemográficas e clínicas. Verificou-se que o colesterol total e a HbA1c apresentaram associação estatisticamente significativa com a adesão ao plano alimentar (p = 0,036) e de exercício físico (p = 0,006). CONCLUSÃO: A chance do paciente com colesterol dentro do valor recomendado apresentar adesão ao plano alimentar é quase cinco vezes a chance do paciente em mau controle lipídico. A chance dos pacientes com mau controle glicêmico apresentarem adesão ao exercício físico é quase duas vezes a chance daquele sem controle adequado da glicemia.

Student Pharmacists’ Perceptions of Barriers to Medication Adherence Counseling

Purpose:

To identify the barriers perceived by student pharmacists to counseling on medication adherence in a supermarket community pharmacy chain.

Methods:

Online surveys were made available to 65 student pharmacists. Subjects completed the survey anonymously and indicated their opinions and perceptions on topics related to medication adherence through the use of a 5-point Likert-type scale.

Results:

Of the surveyed student pharmacists, 26 completed the survey (40%). All participants (100%) agreed that they have knowledge on the importance of medication adherence. Student pharmacists stated that they did not have the time to cover adherence in a counseling session (72.7%) nor did they have time to perform follow-up phone calls with the patient (54.5%). The majority of student pharmacists (81.8%) were comfortable bringing up the topic of adherence with the patient but thought that they did not have access to resources on adherence to provide to the patient (59%).

Conclusions:

Surveyed students indicated they were constrained for time to counsel patients on adherence and to perform continued follow-up with patients afterward. Factors cited as barriers to counseling patients on medication adherence include time, lack of specific training in adherence management, lack of resources to provide to the patient, and patient disinterest in the subject.

Second-year pharmacy students' perceptions of adhering to a complex simulated medication regimen

OBJECTIVE

To conduct a simulated medication regimen with second-year pharmacy students to determine their anticipated versus actual difficulty in adhering to it.

METHODS

Second-year pharmacy students were given 6 fictitious medications (jellybeans) and a drug regimen to adhere to for 6 days. Pre- and post-intervention surveys were conducted to compare participants anticipated vs. actual difficulty with adherence and changes in empathy toward patients.

RESULTS

The 69 (96%) students who participated in the study missed on average 16% of all simulated medication doses and noted that adhering to the complex medication regimen was more difficult than they had anticipated. Eighty-nine percent of students agreed or strongly agreed the project was valuable in developing empathy towards patients taking complex medication regimens.

CONCLUSIONS

Pharmacy students participating in a simulated medication regimen missed a notable number of doses and reported a greater level of empathy for patients taking complex medication regiments. Finding meaningful ways to integrate adherence into the curriculum is essential.
