Cooke CE, Robertson T. Initial non-adherence to lipid-lowering medication: a systematic literature review. BMC PRIMARY CARE 2024; 25:284. [PMID: 39103774 PMCID: PMC11299395 DOI: 10.1186/s12875-024-02524-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 07/15/2024] [Indexed: 08/07/2024]
Abstract
BACKGROUND The impact on cardiovascular health is lost when a patient does not obtain a newly prescribed lipid-lowering medication, a situation termed "initial medication nonadherence" (IMN). This research summarizes the published evidence on the prevalence, associated factors, consequences, and solutions for IMN to prescribed lipid-lowering medication in the United States. METHODS A systematic literature search using PubMed and Google Scholar, along with screening citations of systematic reviews, identified articles published from 2010 to 2021. Studies reporting results of IMN to lipid-lowering medications were included. Studies that evaluated non-adult or non-US populations, used weaker study designs (e.g., case series), or were not written in English were excluded. RESULTS There were 19 articles/18 studies that met inclusion and exclusion criteria. Estimates of the prevalence of IMN to newly prescribed lipid-lowering medications ranged from 10 to 18.2% of patients and 1.4-43.8% of prescriptions (n = 9 studies). Three studies reported prescriber and patient characteristics associated with IMN. Hispanic ethnicity, Black race, lower Charlson Comorbidity Index score and no ED visits or hospitalization were associated with IMN. Lipid lowering prescriptions from primary care providers were also associated with IMN. Four studies described patient-reported reasons for IMN, including preference for lifestyle modifications, lack of perceived need, and side effect concerns. Four intervention studies reported mixed results with automated calls, live calls, or letters. One study reported worse clinical outcomes in patients with IMN: higher levels of low-density lipoprotein and greater risk of emergency department visits. CONCLUSIONS Up to one-fifth of patients fail to obtain a newly prescribed lipid-lowering medication but there is limited information about the clinical consequences. Future research should assess outcomes and determine cost-effective approaches to address IMN to lipid-lowering therapy.

Association between health literacy and medication adherence in chronic diseases: a recent systematic review. Int J Clin Pharm 2023; 45:38-51. [PMID: 36369411 DOI: 10.1007/s11096-022-01470-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 08/04/2022] [Indexed: 11/13/2022]
Abstract
BACKGROUND Poor medication adherence is a serious barrier to successful chronic disease management. Previous reviews reported that low health literacy could be associated with medication non-adherence but conclusions were uncertain. AIM The aim of this systematic review was to clarify the relationship between health literacy and medication adherence in adults with chronic diseases. A secondary objective was to identify the factors that influence medication adherence. METHOD Publications analyzing the relationship between health literacy and adherence in adults with chronic diseases were identified through 6 databases between 2015 and 2020. A quality assessment was conducted in order to improve the interpretation of the relationship between health literacy and medication adherence. A narrative synthesis was then performed to describe the relationship between health literacy and medication adherence. The factors influencing medication adherence were then analyzed as a secondary outcome. RESULTS Among the 27 studies, 17 and 10 were considered to be of good and medium methodological quality, respectively. Concerning the relationship between health literacy and adherence, 14 reported a positive relationship, 1 study suggested a negative relationship, 3 found mixed results, and 9 reported not finding a relationship. Patient-related factors such as medication beliefs, self-efficacy, or medication knowledge, as well as demographic factors such as ethnic minority and incomes influence medication adherence. CONCLUSION The present review confirms an unclear relationship between health literacy and medication adherence. Although health literacy plays a substantial role in medication adherence, other factors must be taken into account when addressing non-adherence.

How to optimize the adherence to a guideline-directed medical therapy in the secondary prevention of cardiovascular diseases: a clinical consensus statement from the European Association of Preventive Cardiology. Eur J Prev Cardiol 2023; 30:149-166. [PMID: 36098041 DOI: 10.1093/eurjpc/zwac204] [Citation(s) in RCA: 27] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 08/20/2022] [Accepted: 09/07/2022] [Indexed: 01/27/2023]
Abstract
A key factor to successful secondary prevention of cardiovascular disease (CVD) is optimal patient adherence to treatment. However, unsatisfactory rates of adherence to treatment for CVD risk factors and CVD have been observed consistently over the last few decades. Hence, achieving optimal adherence to lifestyle measures and guideline-directed medical therapy in secondary prevention and rehabilitation is a great challenge to many healthcare professionals. Therefore, in this European Association of Preventive Cardiology clinical consensus document, a modern reappraisal of the adherence to optimal treatment is provided, together with simple, practical, and feasible suggestions to achieve this goal in the clinical setting, focusing on evidence-based concepts.

Abstract
Hypertension is a frequent finding in elderly patients. Hypertension in older age can be both associated with frailty and represent a risk factor for frailty. Hypertension is recognized as a main risk factor for cardiovascular diseases such as heart failure, atrial fibrillation, and stroke and the occurrence of these diseases may provoke a decline in health status and/or worsen the degree of frailty. Blood pressure targets in hypertensive older and frail patients are not completely defined. However, specific evaluations of individual patients and their co-morbidities and assessment of domains and components of frailty, together with weighted consideration of drug use, may help in finding the appropriate therapy.
