Medication adherence: process for implementation

Pan-European survey on medication adherence management by healthcare professionals

AIMS

While medication adherence (MA) is a key prerequisite for achieving optimal clinical and economic outcomes, nonadherence is highly prevalent. Assessing how healthcare professionals (HCPs) in Europe manage MA, focusing on measurement, reporting and interventions, is the subject of this study.

METHODS

A cross-sectional study was conducted among 40 European countries and quantitative analysis was conducted via an online survey. The multi-language online survey was created using Webropol 3.0 survey and reporting tool. Descriptive statistics and chi-squared tests were applied.

RESULTS

In total, 2875 HCPs (pharmacists: 39.9%; physicians: 36.7%; nurses: 16.4%) from 37 European countries participated. The most used methods for MA assessment were direct communication with patients (86.4%) and referring to personal patient records (56.7%) (P < 0.0001). Physicians (74.9%) and nurses (58.8%) were more aware of problems related to MA in contrast to pharmacists (48.6%) (P < 0.001). Almost all HCPs (92.6%) indicated that MA-enhancing interventions involved mainly direct communication with nonadherent patients (93.3%) and their caregivers (55.7%). Medication review and related optimization of therapy were mainly performed in Western European countries (46.8%). Technological solutions were ranked as one of the less applied approaches (10-15%) (P < 0.001).

CONCLUSIONS

HCPs in all European regions recognize MA management as an integral element of overall patient-centred care. More efforts are needed to ensure timely, adequate and relevant MA assessment, reporting and improvement and involvement of all HCPs, especially among pharmacists who were generally less aware of MA issues. Promotion and use of digital technological solutions should be the focus of current and future clinical practice to optimize MA management processes.

A Predictive Model for Identifying Low Medication Adherence Among Patients with Cirrhosis

Purpose

This study aims to identify the novel risk predictors of low medication adherence of cirrhosis patients in a large cohort and construct an applicable predictive model to provide clinicians with a simple and precise personalized prediction tool.

Patients and Methods

Patients with cirrhosis were recruited from the inpatient populations at the Department of Infectious Diseases of Tangdu Hospital. Patients who did not meet the inclusion criteria were excluded. The primary outcome was medication adherence, which was analyzed by the medication possession ratio (MPR). Potential predictive factors, including demographics, the severity of cirrhosis, knowledge of disease and medical treatment, social support, self-care agency and pill burdens, were collected by questionnaires. Predictive factors were selected by univariable and multivariable logistic regression analysis. Then, a nomogram was constructed. The decision curve analysis (DCA), clinical application curve analysis, ROC curve analysis, Brier score and mean squared error (MSE) score were utilized to assess the performance of the model. In addition, the bootstrapping method was used for internal validation.

Results

Among the enrolled patients (460), most had good or moderate (344, 74.78%) medical adherence. The main risk factors for non-adherence include young age (≤50 years), low education level, low income, short duration of disease (<10 years), low Child-Plush class, poor knowledge of disease and medical treatment, poor social support, low self-care agency and high pill burden. The nomogram comprised these factors showed good calibration and good discrimination (AUC = 0.938, 95% CI = 0.918-0.956; Brier score = 0.14). In addition, the MSE value was 0.03, indicating no overfitting.

Conclusion

This study identified predictive factors regarding low medication adherence among patients with cirrhosis, and a predictive nomogram was constructed. This model could help clinicians identify patients with a high risk of low medication adherence and intervention measures can be taken in time.

A pseudo-customer cross-sectional study to evaluate the community pharmacist's management of migraine in pregnant women

Background

To the best of our knowledge few published studies have been conducted to evaluate customer's care services in community pharmacies in the United Arab Emirates (UAE) using the pseudo-customer model. This further indicates that there is a paucity of information available about the current care services provided by the community pharmacists particularly for pregnant women with migraine.

Objective

The main objective was to evaluate, the effectiveness of the pseudo-customer method on the care services (counseling, advice, and management) provided by the community pharmacists for migraine during pregnancy.

Methods

This was a cross-sectional study conducted in community pharmacies with a cluster sampling of pharmacists. A sample of 200 community pharmacists was recruited from three emirates in the United Arab Emirates. Pregnant woman-related migraine management was assessed using the pseudo-customer model. The used script is not of a real patient but a fake/scripted used to describe the study.

Results

No association was found between the gender and nationality of community pharmacists and the ability to be proactive (P =0.5, 0.568) and between the utilization of source of information and gender (P =0.31). The ability to prescribe by community pharmacists without probing or only after a probe was independent of job title (P =0.310); gender (P =0.44) and nationality (P =0.128). The community pharmacists who have offered written information have had significantly higher odds to dispense medication compared to those who have not (OR =45.547, 95% CI: 2.653 - 782.088, P =0.008). Furthermore, the pharmacists who have been reported to ask for precipitating factors of migraine had significantly higher odds to dispense medication compared to those who have not (OR =11.955, 95% CI: 1.083-131.948, P =0.043). The main outcome was the responses of the community pharmacists to the pseudo-customer visit (pregnant woman with migraine).

Conclusions

The community pharmacist's care services (counseling, advice, and management) offered to the pseudo-customer visits was effective for dealing with migraine during pregnancy.

Adherence to rivaroxaban for the treatment of venous thromboembolism-Results from the FIRST registry

BACKGROUND

Medication nonadherence can result in poor clinical outcomes and significant costs to health care providers. When treating venous thromboembolism (VTE), subtherapeutic anticoagulation may contribute to complications such as recurrent VTE or postthrombotic syndrome.

OBJECTIVES

To describe the extent, reasons for, and predictors of nonadherence to rivaroxaban for the treatment of VTE in clinical practice in the United Kingdom reported by participants of the FIRST registry.

PATIENTS/METHODS

The FIRST registry was an observational, multicenter registry reporting on the use of rivaroxaban in routine clinical practice. FIRST registry participants completed an adherence screening questionnaire during their treatment and follow-up.

RESULTS

In total, 1028 participants completed 1660 questionnaires over 2 years. One hundred thirteen of 1028 (11%) reported nonadherence at 28 days (interquartile range, 21-45). Reasons given for nonadherence at 1 month were forgetfulness (8.6% vs 74.7%; P < .001), carelessness (2.7% vs 27.3%; P < .001) or a change in routine (7.4% vs 25.5%; P < .001) reported by adherent and nonadherent participants, respectively. Older age (10-year increments) was the strongest predictor of good adherence (adjusted odds ratio, 1.21; 95% confidence interval, 1.06-1.39; 1 = adherent).

CONCLUSIONS

Overall adherence to rivaroxaban was high, and most nonadherence was unintentional. Identification of those at risk of nonadherence may reduce the risk of VTE recurrence and long-term complications.

Bridging the evidence-to-practice gap: a stepped-wedge cluster randomized controlled trial evaluating practice facilitation as a strategy to accelerate translation of a multi-level adherence intervention into safety net practices

BACKGROUND

Poor adherence to antihypertensive medications is a significant contributor to the racial gap in rates of blood pressure (BP) control among Latino adults, as compared to Black and White adults. While multi-level interventions (e.g., those aiming to influence practice, providers, and patients) have been efficacious in improving medication adherence in underserved patients with uncontrolled hypertension, the translation of these interventions into routine practice within "real world" safety-net primary care settings has been inadequate and slow. This study will fill this evidence-to-practice gap by evaluating the effectiveness of practice facilitation (PF) as a practical and tailored strategy for implementing Advancing Medication Adherence for Latinos with Hypertension through a Team-based Care Approach (ALTA), a multi-level approach to improving medication adherence and BP control in 10 safety-net practices in New York that serve Latino patients.

METHODS AND DESIGN

We will conduct this study in two phases: (1) a pre-implementation phase where we will refine the PF strategy, informed by the Consolidated Framework for Implementation Research, to facilitate the implementation of ALTA into routine care at the practices; and (2) an implementation phase during which we will evaluate, in a stepped-wedge cluster randomized controlled trial, the effect of the PF strategy on ALTA implementation fidelity (primary outcome), as well as on clinical outcomes (secondary outcomes) at 12 months. Implementation fidelity will be assessed using a mixed methods approach based on the five core dimensions outlined by Proctor's Implementation Outcomes Framework. Clinical outcome measures include BP control (defined as BP< 130/80 mmHg) and medication adherence (assessed using the proportion of days covered via pharmacy records).

DISCUSSION

The study protocol applies rigorous research methods to identify how implementation strategies such as PF may work to expedite the translation process for implementing evidence-based approaches into routine care at safety-net practices to improve health outcomes in Latino patients with hypertension, who suffer disproportionately from poor BP control. By examining the barriers and facilitators that affect implementation, this study will contribute knowledge that will increase the generalizability of its findings to other safety-net practices and guide effective scale-up across primary care practices nationally.

Exit-Knowledge About Dispensed Medications and Associated Factors Among Ambulatory Patients Attending Ayder Comprehensive Specialized Hospital, Mekelle, Ethiopia

BACKGROUND

Optimizing exit-knowledge of ambulatory patients is a major professional responsibility of pharmacists to reassure safe and cost-effective medicines use. The study assessed the exit-knowledge of ambulatory patients on their dispensed medications and associated factors.

PATIENTS AND METHODS

Institutional-based cross-sectional study was conducted among ambulatory patients who visited the outpatient pharmacy of Ayder Comprehensive Specialized Hospital (ACSH) from December 2019 to February 2020. Data were entered, cleaned, and analyzed using SPSS version 20. Binary logistic regression was employed to determine factors associated with exit-knowledge on their dispensed medications. At a 95% confidence interval (CI), p≤0.05 was considered statistically significant.

RESULTS

The study analyzed 400 patients; more than half of the participants were males (55.5%). The mean age of the participants was 41.3 years (mean ± standard deviation (SD), ±13). Less than half of the patients did not recall the name (44.5%) and major side effects (31.2%) of each medication. Furthermore, the overall sufficient knowledge was found to be 81%. Patients with single marital status were 4.454 times to have sufficient exit-knowledge of their dispensed medications than widowed (p=0.050) participants. Besides, patients who responded neutral clarity of pharmacist instruction had 4.745 times sufficient exit-knowledge than those who responded not clear (p=0.049). On the other hand, participants who got "enough" (p<0.0001) and "not enough" (p=0.006) information from the pharmacist were found to have a positive association with sufficient exit-knowledge than those who responded "I do not know".

CONCLUSION

The majority of patients had sufficient exit-knowledge of their dispensed medications. Martially single, neutral clarity of pharmacist's instructions and adequacy of the information delivered by the pharmacist were positively associated with participants' exit-knowledge of their dispensed medications. Hence, conducting a multicenter study, we recommend pharmacists to counsel their patients to underpin patients' knowledge of their dispensed medications.

Recommendations for Providers on Person-Centered Approaches to Assess and Improve Medication Adherence

Medication non-adherence is a significant clinical challenge that adversely affects psychosocial factors, costs, and outcomes that are shared by patients, family members, providers, healthcare systems, payers, and society. Patient-centered care (i.e., involving patients and their families in planning their health care) is increasingly emphasized as a promising approach for improving medication adherence, but clinician education around what this might look like in a busy primary care environment is lacking. We use a case study to demonstrate key skills such as motivational interviewing, counseling, and shared decision-making for clinicians interested in providing patient-centered care in efforts to improve medication adherence. Such patient-centered approaches hold considerable promise for addressing the high rates of non-adherence to medications for chronic conditions.

Effects of Telephone Counseling Intervention by Pharmacists (TelCIP) on Medication Adherence; Results of a Cluster Randomized Trial

OBJECTIVES

To assess the effect of a pharmacist telephone counseling intervention on patients' medication adherence.

DESIGN

Pragmatic cluster randomized controlled trial.

SETTING

53 Community pharmacies in The Netherlands.

PARTICIPANTS

Patients ≥18 years initiating treatment with antidepressants, bisphosphonates, Renin-Angiotensin System (RAS)-inhibitors, or statins (lipid lowering drugs). Pharmacies in arm A provided the intervention for antidepressants and bisphosphonates and usual care for RAS-inhibitors and statins. Pharmacies in arm B provided the intervention for RAS-inhibitors and statins and usual care for antidepressants and bisphosphonates.

INTERVENTION

INTERVENTION consisted of a telephone counseling intervention 7-21 days after the start of therapy. Counseling included assessment of practical and perceptual barriers and provision of information and motivation.

MAIN OUTCOME MEASURE

Primary outcome was refill adherence measured over 1 year expressed as continuous outcome and dichotomous (refill rate≥80%). Secondary outcome was discontinuation within 1 year.

RESULTS

In the control arms 3627 patients were eligible and in the intervention arms 3094 patients. Of the latter, 1054 patients (34%) received the intervention. Intention to treat analysis showed no difference in adherence rates between the intervention and the usual care arm (74.7%, SD 37.5 respectively 74.5%, 37.9). More patients starting with RAS-inhibitors had a refill ratio ≥80% in the intervention arm compared to usual care (81.4 vs. 74.9% with odds ratio (OR) 1.43, 95%CI 1.11-1.99). Comparing patients with counseling to patients with usual care (per protocol analysis), adherence was statistically significant higher for patients starting with RAS-inhibitors, statins and bisphosphonates. Patients initiating antidepressants did not benefit from the intervention.

CONCLUSIONS

Telephone counseling at start of therapy improved adherence in patients initiating RAS-inhibitors. The per protocol analysis indicated an improvement for lipid lowering drugs and bisphosphonates. No effect for on adherence in patients initiating antidepressants was found. The trial was registered at www.trialregister.nl under the identifier NTR3237.

Association between patients' beliefs and oral antidiabetic medication adherence in a Chinese type 2 diabetic population

PURPOSE

The objective of this study was to identify, using the theory of planned behavior (TPB), patients' beliefs about taking oral antidiabetic drugs (OADs) as prescribed, and to measure the correlations between beliefs and medication adherence.

PATIENTS AND METHODS

We performed a cross-sectional study of type 2 diabetic patients using structured questionnaires in a Chinese tertiary hospital. A total of 130 patients were enrolled to be interviewed about TPB variables (behavioral, normative, and control beliefs) relevant to medication adherence. Medication adherence was assessed using the eight-item Morisky Medication Adherence Scale (MMAS-8). Spearman's rank correlation was used to assess the association between TPB and MMAS-8. Logistic regression analysis was performed to examine the relationship between different variables and MMAS-8, with statistical significance determined at P<0.05.

RESULTS

From 130 eligible Chinese patients with an average age of 60.6 years and a male proportion of 50.8%, a nonsignificant relationship between behavioral, normative, and the most facilitating control beliefs and OAD adherence was found in our study. Having the OADs on hand (P=0.037) was the only facilitating control belief associated with adherence behavior. Being away from home or eating out (P=0.000), not accepting the disease (P=0.000), ignorance of life-long drug adherence (P=0.038), being busy (P=0.001), or poor memory (P=0.008) were control belief barriers found to be correlated with poor adherence. TPB is the only important determinant influencing OAD adherence among all the factors (P=0.011).

CONCLUSION

The results indicate that the TPB model could be used to examine adherence to OADs. One facilitating control belief, and most of the barrier control beliefs of TPB were related to medication adherence among Chinese type 2 diabetes inpatients. It will be helpful to understand patients' self-medication and provide methods to develop instruments for identifying factors that influence OAD adherence.

Community Pharmacy-Based Adherence Programs and the Role of Pharmacy Technicians: A Review

Objective: To increase pharmacy technician awareness of medication nonadherence enabling them to identify opportunities to participate in the provision of community pharmacy-based adherence programs. Data Sources: Articles were identified through searches of MEDLINE/PubMed (1950 through December 2014) using the following search terms: "adherence," "role of technicians," "community adherence programs," "adherence and technician's role," "medication synchronization," "retail pharmacy adherence programs," and "CMS Star Ratings." Additionally, resources on adherence programs were used from the American Society of Health-System Pharmacists, the American Pharmacists Association, and the Food and Drug Administration. Study Selection and Data Extraction: Articles describing community pharmacy adherence programs, the role of pharmacy technicians in providing these services, and medication synchronization were included. Data Synthesis: Nonadherence to medications creates a burden in terms of patient health and leads to high health care costs to the patients, providers, and insurers. Initiatives on pharmacist-led adherence programs have proven to reduce these overall health care-related costs. Pharmacy technicians can have an active role in the management of these adherence programs to reduce the burden on community pharmacists who are running adherence programs. Pharmacy technicians can be responsible for gathering medication histories, organizing patient medication lists, making appointment calls to schedule patients, collecting patient demographic history, conducting follow-up calls, and in promoting the program overall. Conclusions: Pharmacy technicians are a valuable asset to the community pharmacists in the process of running adherence programs, and they can work with the pharmacists to coordinate and promote community pharmacy-based medication adherence programs.

Patient considerations in the treatment of COPD: focus on the new combination inhaler umeclidinium/vilanterol

Medication adherence among patients with chronic diseases, such as COPD, may be suboptimal, and many factors contribute to this poor adherence. One major factor is the frequency of medication dosing. Once-daily dosing has been shown to be an important variable in medication adherence in chronic diseases, such as COPD. New inhalers that only require once-daily dosing are becoming more widely available. Combination once-daily inhalers that combine any two of the following three agents are now available: 1) a long-acting muscarinic antagonist; 2) a long acting beta2 agonist; and 3) an inhaled corticosteroid. A new once-daily inhaler with both a long-acting muscarinic antagonist, umeclidinium bromide, and a long acting beta2 agonist, vilanterol trifenatate, is now available worldwide for COPD treatment. It provides COPD patients convenience, efficacy, and a very favorable adverse-effects profile. Additional once-daily combination inhalers are available or will soon be available for COPD patients worldwide. The use of once-daily combination inhalers will likely become the standard maintenance management approach in the treatment of COPD because they improve medication adherence.
