Levels of adherence to treatment, illness perception and acceptance of illness in patients with coronary artery disease - descriptive and correlational study. BMC Cardiovasc Disord 2024; 24:171. [PMID: 38509506 PMCID: PMC10953129 DOI: 10.1186/s12872-024-03827-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 03/04/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND Understanding the disease and its acceptance significantly influence adherence to prescribed medications, a critical aspect in managing coronary artery disease (CAD). This study is designed to explore the multifaceted factors influencing medication adherence specifically in CAD patients. Of particular interest is investigating the interconnectedness between medication adherence, the perception of illness, and the level of acceptance of the illness itself among these individuals. METHODS This cross-sectional study involved 280 confirmed CAD patients who were selected through a convenience sampling method adhering to predefined inclusion criteria. The study was conducted between March and September 2023. Three primary parameters-medication adherence, illness perception, and acceptance of illness-were evaluated using standardized tools: The Morisky Medication Adherence Scale-8, Illness Perception Questionnaire-Brief, and Acceptance of Illness Scale. Statistical analyses using SPSS (version 25) were used to analyze the data. RESULTS Patients had moderate illness perception (51.82 ± 7.58) and low acceptance to illness (16.98 ± 4.75), and 61.8 of them adhered to their medication regimen. A positive relationship between acceptance of illness and medication adherence (r = 0.435, p-value < 0.01) was found. Level of education, type of drug and marital status had significantly impact on medication adherence, and gender, level of education, intention to stop drug and marital status were associated with acceptance of illness (p < 0.05). CONCLUSION These results underscore the pivotal role of medication adherence in CAD management. Future interventions should target improving illness perception and acceptance of illness among CAD patients to enhance their overall adherence to prescribed medications and ultimately improve disease management.

Effectiveness of low-density lipoprotein cholesterol reduction with lipid lowering therapy for secondary prevention amongst older individuals: a nationwide cohort study. Age Ageing 2024; 53:afad241. [PMID: 38219226 DOI: 10.1093/ageing/afad241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Indexed: 01/16/2024] Open
Abstract
BACKGROUND Data about the clinical benefit from initial low-density lipoprotein cholesterol (LDL-C) reduction with lipid lowering treatment for secondary prevention and risk of major vascular events amongst older as compared with younger individuals treated during routine clinical care are limited. We investigated this in a nationwide cohort. METHODS Individuals aged ≥ 50 years with a first-time hospitalisation for a cardiovascular event (index event, including acute coronary syndrome, non-haemorrhagic stroke, transient ischaemic attack and coronary revascularisation), 1 January 2008 to 31 October 2018, who subsequently used lipid lowering treatment, and had an LDL-C measurement before and after the event were included. Hazard ratios (HRs) for major vascular events per 1 mmol/L reduction in LDL-C were estimated for the included 21,751 older and 22,681 younger individuals (≥/<70 years old) using Cox regression. RESULTS LDL-C lowering was associated with a 12% lower risk of major vascular events in older individuals per 1 mmol/L reduction in LDL-C (HR 0.88, 95% confidence interval [CI] 0.84-0.93), with no significant difference compared with the risk reduction amongst younger individuals (HR 0.88, 95% CI 0.83-0.93; P-value for difference between age groups: 0.86). The risk reduction was more pronounced when post hoc restricting, as a proxy for compliance, to new users with an LDL-C reduction above the lowest decile for both older (0.81, 95% CI 0.73-0.90) and younger (0.81, 95% CI 0.72-0.91) individuals. CONCLUSIONS This study strongly supports a similar relative clinical benefit of LDL-C reduction with lipid lowering treatment for secondary prevention of major vascular events amongst individuals aged ≥70 and <70 years.

SAGE Open Nurs 2023; 9:23779608231171772. [PMID: 37334063 PMCID: PMC10272659 DOI: 10.1177/23779608231171772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 04/02/2023] [Accepted: 04/07/2023] [Indexed: 06/20/2023] Open
Abstract
Introduction Illness perception and self-efficacy in patients with coronary artery disease (CAD) may affect medication adherence, which is one of the most important challenges in disease management in this group of patients. Objective The present study aimed to investigate the factors influencing medication adherence in CAD patients, especially the effect of illness perception and self-efficacy. Methods This study was cross-sectional and conducted from April to September 2021. A total of 259 patients with confirmed CAD were selected by convenience sampling method based on inclusion criteria. Illness perception, self-efficacy, and medication adherence were investigated using Brief IPQ, SCSES, and MARS_10 questionnaires, respectively. The data were analyzed using the STATA software (version 14) and the regression path analysis method. Results Patients had moderate illness perception and high self-efficacy, and 61.8 of them adhered to their medication regimen. Greater illness perception, better self-efficacy, and higher education had a positive effect on medication adherence, and increasing age had a negative effect on it. The final path model shows a good fit of the data in the model (χ2: 0.37, df: 274, χ2/df: 0.36, CFI: 1, IFI: 0.95, TLI: 1.07, and RMSEA: 0.00). Conclusion The results of the present study suggest that patients' illness perception can play an important role in predicting self-efficacy in disease management and the level of medication adherence in patients with CAD. To improve self-efficacy and medication adherence, future intervention studies should focus on the patient's illness perceptions and their improvement.

Engebretsen I, Munkhaugen J, Bugge C, Halvorsen S, Ødegaard KM, Støvring H, Kristiansen IS. Gaps and discontinuation of statin treatment in Norway: potential for optimizing management of lipid lowering drugs. EUROPEAN HEART JOURNAL OPEN 2022; 2:oeac070. [PMID: 36440353 PMCID: PMC9683394 DOI: 10.1093/ehjopen/oeac070] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 10/03/2022] [Indexed: 05/31/2023]
Abstract
Aims In clinical practice, many patients do not reach the recommended treatment targets for LDL-cholesterol levels. We aimed to examine treatment patterns and adherence for patients on lipid lowering drugs in Norway to inform future strategies to improve therapies. Methods and results We obtained information on all dispensed statins, ezetimibe, and proprotein convertase subtilisin/-kexin 9 (PCSK9) inhibitors 2010-2019 from the Norwegian Prescription Database. Treatment gaps were assessed assuming patients take one tablet per day and were defined to occur if a patient did not refill a prescription when the previous one should have been depleted. Treatment was defined as discontinued when the preceding prescription would have been used and no new subsequent prescription was filled. The mean proportion of days covered (PDC) was calculated by aggregating the total number of tablets dispensed during each calendar year and dividing by 365. Patients 80 years were excluded. A considerable proportion of statin users in Norway had long treatment gaps or discontinuation in treatment. The 19.6% of the patients had treatment gaps of 180 days or more, and 10.8% had gaps or greater than 365 days. Similar results were found for patients on antidiabetics and hypertensives. PDC ranged from 84.9% for simvastatin to 72.2% for ezetimibe (2019). The most common lipid lowering drugs in 2019 were atorvastatin, simvastatin, and ezetimibe. Conclusion There is a great potential for improving drug adherence and optimizing lipid lowering therapy by switching to more effective statins in greater doses, and more often add ezetimibe and PCSK9 inhibitors to treatment.
