- Poor adherence to efficacious cardiovascular-related medications has led to considerable morbidity, mortality, and avoidable health care costs. This article provides results of a recent think-tank meeting in which various stakeholder groups representing key experts from consumers, community health providers, the academic community, decision-making government officials (Food and Drug Administration, National Institutes of Health, etc), and industry scientists met to evaluate the current status of medication adherence and provide recommendations for improving outcomes. Below, we review the magnitude of the problem of medication adherence, prevalence, impact, and cost. We then summarize proven effective approaches and conclude with a discussion of recommendations to address this growing and significant public health issue of medication nonadherence.

- BACKGROUND: Chronic heart failure (CHF) is an important cause of hospital admission and death. Poor adherence to medication is common in some chronic illnesses and might reduce the population effectiveness of proven treatments. Because little is known about adherence in patients with CHF and about the consequences of non-adherence, we assessed the association between adherence and clinical outcome in the CHARM (Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity) programme. METHODS: CHARM was a double-blind, randomised, controlled clinical trial, comparing the effects of the angiotensin receptor blocker candesartan with placebo in 7599 patients with CHF. Median follow-up was 38 months. The proportion of time patients took more than 80% of their study medication was defined as good adherence and 80% or less as poor adherence. We used a Cox proportional hazards regression model, with adherence as a time-dependent covariate in the model, to examine the association between adherence and mortality in the candesartan and placebo groups. FINDINGS: We excluded 187 patients because of missing information on adherence. In the time-dependent Cox regression model, after adjustment for predictive factors (demographics, physiological and severity-of-illness variables, smoking history, and number of concomitant medications), good adherence was associated with lower all-cause mortality in all patients (hazard ratio [HR] 0.65, 95% CI 0.57-0.75, p<0.0001). The adjusted HR for good adherence was similar in the candesartan (0.66, 0.55-0.81, p<0.0001) and placebo (0.64, 0.53-0.78, p<0.0001) groups. INTERPRETATION: Good adherence to medication is associated with a lower risk of death than poor adherence in patients with CHF, irrespective of assigned treatment. This finding suggests that adherence is a marker for adherence to effective treatments other than study medications, or to other adherence behaviours that affect outcome. Understanding these factors could provide an opportunity for new interventions, including those aimed at improving adherence.

- AIMS: Although many patients with heart failure have incomplete adherence to prescribed medications, predisposing factors remain unclear. This analysis investigates factors associated with adherence, with particular emphasis on age and sex. METHODS AND RESULTS: A multivariable regression analysis of 7599 heart failure patients from the CHARM trial was done to evaluate factors associated with adherence. Adherence was measured as the proportion of time patients took more than 80% of study medication. The mean age was 66 years (SD 11) and 31.5% (n = 2400) were women. Women were slightly less adherent than men (87.3 vs. 89.8%, P = 0.002), even in adjusted, multivariable models (treatment, P = 0.006; placebo P = 0.004; and overall P < 0.001). However, all-cause mortality was lower in women (21.5%) than in men (25.3%) (adjusted hazard ratio, 0.77; 95% CI, 0.69-0.86; P < 0.001), but patients with a low adherence regardless of sex had a higher mortality. Age, severity of heart failure, number of medications, and smoking status were not associated with adherence. CONCLUSION: Women, particularly those <75 years of age, were less likely to be adherent in this large sample of patients with symptomatic heart failure. Understanding factors associated with adherence may provide opportunities for intervention.

- Background Poor adherence to evidence-based medications in heart failure (HF) is a major cause of avoidable hospitalizations, disability, and death. To test the feasibility of improving medication adherence, we performed a randomized proof-of-concept study of a self-management intervention in high-risk patients with HF. Methods Patients with HF who screened positively for poor adherence (<6 Morisky Medication Adherence Scale 8-item) were randomized to either the intervention or attention control group. In the intervention group (n = 44), a nurse conducted self-management training before discharge that focused on identification of medication goals, facilitation of medication-symptom associations, and use of a symptom response plan. The attention control group (n = 42) received usual care; both groups received follow-up calls at 1 week. However, the content of follow-up calls for the attention control group was unrelated to HF medications or symptoms. General linear mixed models were used to evaluate the magnitude of change in adherence and symptom-related events at 3-, 6-, and 12-month follow-up clinic visits. Efficacy was measured as improved medication adherence using nurse-assessed pill counts at each time point. Results Pooled over all time points, patients in the intervention group were more likely to be adherent to medications compared with patients in the attention control group (odds ratio 3.92, t = 3.51, P = .0007). Conclusions A nurse-delivered, self-care intervention improved medication adherence in patients with advanced HF. Further work is needed to examine whether this intervention can be sustained to improve clinical outcomes.

- BACKGROUND: The purpose of this study was to explore the theoretical linkages between symptom experiences and meaning associated with medication adherence. The specific objectives were to evaluate the key constructs of Meaning-Response theory for understanding medication adherence in patients with chronic heart failure; to assess the influence of symptom persistence on the meaning associated with prescribed medicines; and to explore the extent to which meaningful associations improve medication adherence. Among patients with heart failure, poor medication adherence occurs in over half of the population, resulting in high rates of symptom exacerbation, avoidable hospitalization, and death. Nurses play a key role in facilitating self-management skills, but patients' perceptions of the relationship between symptoms and medicines is not clear. METHODS: Using a prospective mixed methods design, the study assessed patients' (n=10) perception of chronic heart failure symptoms and medication adherence. Patients completed guided interviews related to six concepts of meaning ascribed to medication use and four standardized measures of medication-related beliefs, behaviours, symptoms, and satisfaction. RESULTS: This study suggests that patients' perception of meaning associated with medication taking was categorized as positive, negative, or absent. Symptom persistence influenced a majority of patient beliefs in the efficacy medicines, and patients with more positive meaningful associations with their medicines were more likely to remain adherent during the course of this study. CONCLUSIONS: Development of meaningful associations with medicines may improve long-term adherence with prescribed medication in heart failure.

- AIM:This paper is a report of a study to describe patient and nurse perceptions of patient satisfaction with information about the medicines at two heart failure clinics after medication up-titration and information-giving.BACKGROUND:Chronic heart failure is a major cause of hospitalization. Poor adherence to medications increases mortality and heart failure-related hospitalizations. To achieve mutual goal-setting (concordance) regarding medication-taking behaviours, health providers need to understand patient information needs regarding the prescribed medicines.METHODS:A convenience sample of 56 patients with chronic heart failure referred for an up-titration of medicines and information-giving about the condition and treatment completed the Satisfaction about Information about Medicines Scale at their first and last visits. Nurses completed the same questionnaire after each patient's final visit, assessing the patient's need for further information. The data were collected between 2002 and 2004.RESULTS:Patient scores indicated statistically significantly more satisfaction with their information at the final visit compared with the first visit (P = 0.005). However, at the programme conclusion, nurses (n = 7) rated patients to be appropriately informed while patients reported a persistent need for further information (P = 0.011).CONCLUSION:Further research should evaluate more advanced pedagogical strategies such as how to address patients' expectations about the effect of medicines when actual effects of the treatment are related to mortality and morbidity at the population level and may not result directly in symptom relief at an individual level.

- Ineffective medication management contributes to repeated hospitalisation and death among patients with heart failure. The meaning ascribed to medications and the influence of meaning on how patients manage medications is unknown. The purpose of this study was to explore the meaning and expectations associated with medication use in high-risk, non-adherent patients with heart failure.Patients ( n=265) with heart failure were screened for adherence to prescribed medication using the Morisky medication adherence scale (MMAS). Patients (MMAS score <6; n=44) participated in semistructured interviews, analysed using qualitative content analysis. Of 17 initial themes (223 representative segments), the overarching theme 'unmet expectations' consisted of two subthemes 'working to be heard' by professionals and 'resignation' to both the illness and medications. Patients' expectations were challenged by unexpected work to communicate with providers in general (72 representative segments), and specifically regarding medications (118 representative segments) and feelings of resignation regarding the medication regimen (33 representative segments).These findings suggest that unmet expectations contribute to poor medication management. Improved listening and communication by providers, to establish a common understanding and plan for managing medications may strengthen patient beliefs, resolve feelings of resignation and improve patients' ability to manage medications effectively.

- Fatigue is a common symptom in patients with chronic heart failure (CHF). Characteristics of the experience and consequences of fatigue might be unique in these patients. The authors interviewed 15 patients with CHF and analyzed focused online observations of the content discussed in an Internet patient discussion group concerning CHF using grounded theory. The results suggest that fatigue is a circular process in which the consequences of fatigue further exaggerate the experience. However, fatigue could be alleviated by restorative activities. The bodily experience of fatigue was defined as lacking strength and energy and feeling sleepy. Patients reported the mental aspects of fatigue as demoralizing and that they frequently experienced intellectual deficiency. Fatigue leads to sacrificing, which was manifested as refraining, denying oneself, and being isolated. The restoring activities included the categories involuntarily attentive, socially interactive, and mentally absorbed. Interventions aimed to relieve fatigue should focus on restorative activities.

Tidskriftsartikel (refereegranskat)abstract
- Chronic heart failure (CHF) is a costly Medicare expenditure, with approximately 70% of the costs of heart failure care attributable to acute, symptom-related hospitalizations. The most common preventable cause of rehospitalization is nonadherence to the CHF regimen. Theoretic models have been used to study adherence; however, these models are predominantly designed for health behavior interventions (ie, smoking cessation, diet modification, or exercise) and focus less on conceptualizing the work involved in carrying out complex self-care regimens. The purpose of this paper was to present one approach for operationalizing the Trajectory Theory of Chronic Illness to study adherence in patients with heart failure. The trajectory model offers unique opportunities to study adherence, specifically because measurable patient attributes are clearer when evaluated in the context of the work required to adhere over time. Using trajectory theory may allow providers to better understand and facilitate patient adherence to the CHF regimen.
