Significant Improvement In Medication Adherence Research Articles

The Effect of Nurse-Led Motivational Interviewing on Medication Adherence in Patients With Bipolar Disorder

The purpose of this study was to test the effect of motivational interviewing (MI) on medication adherence in patients with bipolar disorder (BD) in an outpatient setting. Pretest-posttest design was used. The 3-week MI intervention consisted of one face-to-face session and two follow-up telephone interventions. Outcome measures included medication adherence, self-efficacy, and motivation to change. Participants demonstrated significant improvement in medication adherence, self-efficacy, and motivation to change after receiving the MI. MI shows promising results as a treatment approach to improve medication adherence in adults with BD. Psychiatric-mental health nurse practitioners could improve client health outcomes by implementing MI techniques.

Improving Maintenance Medication Adherence in Adult Inflammatory Bowel Disease Patients: A Pilot Study.

Medication nonadherence in inflammatory bowel disease (IBD) may lead to suboptimal control of the disease, decreased quality of life, and poor outcomes. This pilot study evaluated the feasibility, intervention mechanism, and potential effectiveness of a three-month continuous self-improvement (CSI) intervention to enhance medication adherence (MA) in adult nonadherent IBD patients. Adult IBD patients taking a daily or twice-daily dosed maintenance medication were screened electronically for two months to determine baseline MA levels. Nonadherent IBD participants were randomized to the CSI or the attention control (AC) intervention and monitored for three months. The CSI intervention consisted of a data evaluation and system refinement process in which system changes were identified and implemented. The AC group was given educational information regarding IBD disease process, extra-intestinal manifestations of IBD, and medical therapy. Demographic statistics, change scores for within and between-group differences, and effect size estimates were calculated. Nine nonadherent participants (medication adherence score <0.85) were eligible for randomization. The intervention was found feasible and acceptable. Although no statistically significant improvement in MA was found (P=0.14), adherence improved in 3 of 4 of the CSI group and 1 of 2 in the attention control group. The effect size calculation of 1.9 will determine the sample size for future study. The results of this pilot study showed the intervention was feasible and had a positive effect on MA change score and adherence levels. A larger fully powered study is needed to test of the effectiveness of this innovative intervention.

Mobile Health Medication Adherence and Blood Pressure Control in Renal Transplant Recipients: A Proof-of-Concept Randomized Controlled Trial

BackgroundMobile phone based programs for kidney transplant recipients are promising tools for improving long-term graft outcomes and better managing comorbidities (eg, hypertension, diabetes). These tools provide an easy to use self-management framework allowing optimal medication adherence that is guided by the patients’ physiological data. This technology is also relatively inexpensive, has an intuitive interface, and provides the capability for real-time personalized feedback to help motivate patient self-efficacy. Automated summary reports of patients’ adherence and blood pressure can easily be uploaded to providers’ networks helping reduce clinical inertia by reducing regimen alteration time.ObjectiveThe aim of this study was to assess the feasibility, acceptability, and preliminary outcomes of a prototype mobile health (mHealth) medication and blood pressure (BP) self-management system for kidney transplant patients with uncontrolled hypertension.MethodsA smartphone enabled medication adherence and BP self-management system was developed using a patient and provider centered design. The development framework utilized self-determination theory with iterative stages that were guided and refined based on patient/provider feedback. A 3-month proof-of-concept randomized controlled trial was conducted in 20 hypertensive kidney transplant patients identified as non-adherent to their current medication regimen based on a month long screening using an electronic medication tray. Participants randomized to the mHealth intervention had the reminder functions of their electronic medication tray enabled and received a bluetooth capable BP monitor and a smartphone that received and transmitted encrypted physiological data and delivered reminders to measure BP using text messaging. Controls received standard of care and their adherence continued to be monitored with the medication tray reminders turned off. Providers received weekly summary reports of patient medication adherence and BP readings.ResultsParticipation and retention rates were 41/55 (75%) and 31/34 (91%), respectively. The prototype system appears to be safe, highly acceptable, and useful to patients and providers. Compared to the standard care control group (SC), the mHealth intervention group exhibited significant improvements in medication adherence and significant reductions in clinic-measured systolic blood pressures across the monthly evaluations. Physicians made more anti-hypertensive medication adjustments in the mHealth group versus the standard care group (7 adjustments in 5 patients versus 3 adjustments in 3 patients) during the 3-month trial based on the information provided in the weekly reports.ConclusionsThese data support the acceptability and feasibility of the prototype mHealth system. Further trials with larger sample sizes and additional biomarkers (eg, whole blood medication levels) are needed to examine efficacy and effectiveness of the system for improving medication adherence and blood pressure control after kidney transplantation over longer time periods.Trial RegistrationClinicaltrials.gov NCT01859273; http://clinicaltrials.gov/ct2/show/NCT01859273 (Archived by WebCite at http://www.webcitation.org/6IqfCa3A3).

Web 2.0 Chronic Disease Self-Management for Older Adults: A Systematic Review

BackgroundParticipatory Web 2.0 interventions promote collaboration to support chronic disease self-management. Growth in Web 2.0 interventions has led to the emergence of e-patient communication tools that enable older adults to (1) locate and share disease management information and (2) receive interactive healthcare advice. The evolution of older e-patients contributing to Web 2.0 health and medical forums has led to greater opportunities for achieving better chronic disease outcomes. To date, there are no review articles investigating the planning, implementation, and evaluation of Web 2.0 chronic disease self-management interventions for older adults.ObjectiveTo review the planning, implementation, and overall effectiveness of Web 2.0 self-management interventions for older adults (mean age ≥ 50) with one or more chronic disease(s).MethodsA systematic literature search was conducted using six popular health science databases. The RE-AIM (Reach, Efficacy, Adoption, Implementation and Maintenance) model was used to organize findings and compute a study quality score (SQS) for 15 reviewed articles.ResultsMost interventions were adopted for delivery by multidisciplinary healthcare teams and tested among small samples of white females with diabetes. Studies indicated that Web 2.0 participants felt greater self-efficacy for managing their disease(s) and benefitted from communicating with health care providers and/or website moderators to receive feedback and social support. Participants noted asynchronous communication tools (eg, email, discussion boards) and progress tracking features (eg, graphical displays of uploaded personal data) as being particularly useful for self-management support. Despite high attrition being noted as problematic, this review suggests that greater Web 2.0 engagement may be associated with improvements in health behaviors (eg, physical activity) and health status (eg, HRQoL). However, few studies indicated statistically significant improvements in medication adherence, biological outcomes, or health care utilization. Mean SQS scores were notably low (mean=63%, SD 18%). Studies were judged to be weakest on the Maintenance dimension of RE-AIM; 13 reviewed studies (87%) did not describe any measures taken to sustain Web 2.0 effects past designated study time periods. Detailed process and impact evaluation frameworks were also missing in almost half (n=7) of the reviewed interventions.ConclusionsThere is need for a greater understanding of the costs and benefits associated with using patient-centered Web 2.0 technologies for chronic disease self-management. More research is needed to determine whether the long-term effectiveness of these programs is sustainable among larger, more diverse samples of chronically ill patients. The effective translation of new knowledge, social technologies, and engagement techniques will likely result in novel approaches for empowering, engaging, and educating older adults with chronic disease.

Systematic Review of Consistency between Adherence to Cardiovascular or Diabetes Medication and Health Literacy in Older Adults

To review the relationship between health literacy and adherence to cardiovascular/diabetes medication. We searched EMBASE (1974-February 2012) and MEDLINE (1948-February 2012). Search terms included health literacy, numeracy, health education and related terms, health literacy measurement tools, and medication adherence. English-language articles of all study designs were considered. Articles were included if they had a measurement of health literacy and medication adherence and if participants were older adults taking drugs for cardiovascular illness or diabetes mellitus. A total of 1310 citations were reviewed, including 9 articles that reported on 7 research studies. Most studies were retrospective, and all were based in the US. Because there was considerable diversity in measurements, participant characteristics, and outcome measures, we conducted a narrative synthesis rather than a meta-analysis. In assessing study validity, we looked at participant selection, method of measuring health literacy and medication adherence, missing data or losses, and adjustment for confounders. Of the 7 included studies, only 1 found a demonstrable association between health literacy and refill adherence. One clinical trial failed to show significant improvements in medication adherence after an intervention to improve health literacy. The current evidence does not show a definite association between health literacy and medication adherence in older adults with cardiovascular disease or diabetes mellitus. In the absence of a definite link, efforts to develop interventions to improve health literacy would not necessarily improve adherence to cardiovascular medications. There is an urgent need for robust studies outside of the US, with wider, generalized recruitment of participants.

Medication Adherence Improvements in Employees Participating in a Pharmacist-Run Risk Reduction Program

Objective: To evaluate the medication adherence of individuals participating in a pharmacist-run employee health Cardiovascular and Diabetes Risk Reduction Program.&#x0D; Design: Retrospective analysis of medication adherence using pharmacy refill data.&#x0D; Setting: A medium sized university located in the Midwest United States and the organization's outpatient pharmacy. Participants: 38 participants ≥ 18 years of age, employed and receiving their health insurance through the organization, and have a diagnosis of hypertension, hyperlipidemia, diabetes mellitus, or a combination thereof.&#x0D; Intervention: Participation in the risk reduction program that emphasizes medication therapy management (MTM), lifestyle medicine and care coordination.&#x0D; Main Outcome Measures: The Proportion of Days Covered (PDC) and the Medication Possession Ratio (MPR).&#x0D; Results: PDC and MPR analysis showed a statistically significant improvement in medication adherence for 180 days and 360 days post enrollment versus the 180 days prior to enrollment (P&lt;0.01). The PDC analysis demonstrated a statistically significant improvement in the number of medications that achieved a PDC ≥ 80% (high adherence) for the 180 days post enrollment versus the 180 days prior to enrollment (+30%, P&lt;0.01). The MPR analysis showed a non-statistically significant improvement in the number of medications that achieved an MPR ≥ 80% (high adherence) pre enrollment versus post enrollment (+10%, P=0.086). The percentage of participants in the program that reached a PDC and MPR adherence rate ≥ 80% at 180 days post enrollment was 78.9% and 94.4%, respectively which exceeds that of a matched cohort that reached a PDC and MPR adherence rate ≥ 80% of 66.4% and 82.8%, respectively.&#x0D; Conclusion: Pharmacists can improve medication adherence as measured by PDC and MPR when working with employees enrolled in a novel pharmacist-run employee health risk reduction program. Medication adherence was shown to be sustainable for at least one year and was shown to be better when compared to a matched cohort of similar age, condition and region.&#x0D; &#x0D; Type: Original Research

Does assertive community treatment increase medication adherence for people with co-occurring psychotic and substance use disorders?

This study analyzed data from a randomized trial to examine the impact on medication adherence of integrated treatment delivered via assertive community treatment (ACT) versus standard clinical case management (SCCM). Data from the original study included 198 study participants with co-occurring psychotic and substance use disorders who were randomly assigned to receive integrated treatment via ACT or SCCM and were followed for 3 years. We applied mixed-effects logistic regression to estimate group (ACT vs. SCCM) by time effects on a self-report measure of medication adherence. Adherence was dichotomized as 20% or more missed medication days ("poor adherence") versus less than 20% missed medication days ("adequate adherence"). Participants who were assigned to ACT reported significant improvement in medication adherence compared with those assigned to SCCM. Integrated treatment delivered via ACT may benefit persons with co-occurring psychotic and substance use disorders who are poorly adherent to medications.

Medication Adherence in People of Culturally and Linguistically Diverse Backgrounds: A Meta-Analysis

Medication adherence is of particular importance for people of culturally and linguistically diverse (CALD) backgrounds due to language difficulties, lack of social and organizational supports, lack of access to healthcare resources, and disengagement with the health-care system. To evaluate the impact of interventions to improve medication adherence in people of CALD backgrounds through a systematic review and meta-analysis. A search was performed using the following databases: Cochrane Database of Systematic Reviews, Cumulative Index to Nursing & Allied Health Literature, EMBASE, Journals@Ovid, PsychInfo, PubMed, Science Direct, Scopus, and Web of Science. Databases were searched from January 1978 to October 2009. Forty-six articles reviewed were assessed as being relevant, which included 36 randomized controlled trials, 2 observational cohort studies, and 8 quasi-experimental studies. The most common method for assessing medication adherence was self-reporting measures, such as the Morisky Scale and its modifications. Few studies used combinations of adherence measures, and adherence involving a medication event monitoring system (MEMS) was used in only 6 studies. Individuals of CALD backgrounds were recruited with people of non-CALD backgrounds and subsequent analyses tended to be undertaken of the whole sample. Twenty studies showed statistically significant improvements in medication adherence, 15 of which were randomized controlled trials. Six of the successful interventions involved delivery by a bilingual person or the use of translated materials and 4 involved the use of a conceptual model. Meta-analyses demonstrated modest improvements in medication adherence. Relatively little high-quality work has been conducted on adherence-enhancing interventions for people of CALD backgrounds. Greater attention needs to be given to examining the needs of specific CALD population groups. Future researchers should consider rigorously testing interventions that take into account the enormous diversity and differences that exist within any particular CALD group.

Improved Adherence and Outcomes for Pediatric Liver Transplant Recipients by Using Text Messaging

The goal was to improve immunosuppressant adherence for pediatric patients with orthotopic liver transplants by using text messaging (TM). A prospective study of sending TM reminders to the primary medication administrator (patient or caregiver) for pediatric transplant recipients was performed. Patient records were reviewed, comparing the year before and the year of the study. The SD of serum tacrolimus levels was used as an indicator of adherence. Forty-one patients provided consent. The median age was 15 years (range: 1-27 years), and the median age at the time of transplantation was 2 years (range: 4 months to 23 years). Fourteen patients (34%) were male. In 29 of 41 cases, the medications were self-administered by the patient. The mean duration of study was 13 +/- 1.5 months. Twenty-two patients were receiving 1 immunosuppressant, 14 were receiving 2, and 5 were receiving 3. Thirteen patients (37%) stopped the study after 4 months. The mean tacrolimus level SD decreased from 3.46 microg/L before the study to 1.37 microg/L (P < .005). The number of immunosuppressants taken and patient self/caregiver medication administration did not significantly affect the results. The number of acute cellular rejection episodes decreased from 12 to 2 during the study. Risk factors for rejection were older age (17.67 vs 13.28 years) and administration of >1 immunosuppressant. We observed significant improvement in medication adherence and a reduction in rejection episodes with TM reminders for pediatric recipients of liver transplants.

Review of long-acting stimulants in the treatment of attention deficit hyperactivity disorder

A number of long-acting medications for the treatment of attention deficit hyperactivity disorder (ADHD) have recently been developed and approved for use in the US. These compounds are intended to optimize and maintain ADHD symptom control throughout the day, while eliminating problems associated with short-acting medications, such as the need for in-school, midday or multiple daily doses. Recent reports confirm that the safety and tolerability of long-acting medications are similar to those of short-acting medications, although long-acting medications appear to have a lower risk of abuse and diversion and may be associated with significant improvements in medication adherence. Distinctions can be made among the long-acting medications with regard to the onset, magnitude and duration of their clinical effects. Recognition of these differences is important for individualizing treatment for patients with ADHD.

Learning Preferences of Caregivers of Asthmatic Children

Purpose of the Study. To determine the learning styles of the caregivers of asthmatic children seen in a pediatric allergy and immunology clinic. Study Population. Parents of asthmatic children seen in a tertiary care pediatric allergy and immunology clinic. Methods. Caregivers completed the Visual-Aural-Read/Write-Kinesthetic (VARK) questionnaire anonymously, and the responses were evaluated on the basis of previously validated scoring instructions. Results. Analysis of 98 respondents showed that 42% had a single learning-modality preference, and the remaining 58% were multimodal learners. Of those who reported a single mode of learning, 61% preferred kinesthetic, 27% preferred reading/writing, and &amp;lt;1% each preferred aural or visual stimuli. Of all 98 caregivers, 82% included kinesthetic as a learning preference, 59% included reading/writing, 50% included aural stimuli, and 41% included visual stimuli. Conclusions. The majority of caregivers preferred the kinesthetic learning method, whether as a single learning preference or in combination with other approaches. Incorporating kinesthetic methods of learning, such as role playing and problem-solving case scenarios, into standardized asthma education curricula may be beneficial to patients and families in terms of understanding and using their regimen. Reviewer Comments. This is a novel study that attempted to improve asthma care by identifying the learning preferences of the caretakers of asthmatic children. Asthma regimens can be complex, and simplification and understanding of these regimens can improve overall adherence. Individual caretakers demonstrate multiple modes of learning preference, and the current educational modules should focus on role playing and other visual modalities to enhance the understanding of the caretakers’ asthma knowledge. Streamlining and improving these educational methods could result in significant improvement in medication adherence, symptom recognition, and appropriate utilization of medical care.

A Systematic Review of the Effects of Home Blood Pressure Monitoring on Medication Adherence

Home blood pressure monitoring (HBPM) improves blood pressure control, but little is known about its effects on medication adherence. The authors conducted a systematic review of the published literature on the effects of HBPM on medication adherence. Of 440 abstracts and citations reviewed, 11 randomized control trials met predefined criteria. Six of the 11 randomized controlled trials reported statistically significant improvement in medication adherence; 84% of these were complex interventions involving the use of HBPM in combination with other adherence-enhancing strategies such as patient counseling by nurses, pharmacists, or a telephone-linked system; patient education; and the use of timed medication reminders. Interventions conducted in primary care settings were not effective compared with those that occurred in hospital-based clinics or nonclinical settings. The data on the effects of HBPM on patients' medication-taking behavior are mixed. Future studies should investigate the independent effects of HBPM in primary care practices where the majority of hypertensive patients receive their care.
