Book A Mixed Methods Investigation of the Barriers and Facilitators to Medication Adherence in Patients with Type 2 Diabetes Across Different Health Literacy Levels

Download or read book A Mixed Methods Investigation of the Barriers and Facilitators to Medication Adherence in Patients with Type 2 Diabetes Across Different Health Literacy Levels written by Yen-Ming Huang (Ph.D.) and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Type 2 diabetes (T2D) is the leading cause of death in the U.S., and it incurs tremendous health expenditures associated with various complications due to poor diabetes control. Medication adherence, which is correlated with patients' health literacy, should be consistently practiced in order to achieve optimal diabetes control. However, no literature has systematically explored the multiple psychosocial and communication barriers and facilitators at the individual level that mediate the linkage between health literacy and medication adherence. A deeper understanding of the specific communication and psychosocial factors related to medication-taking behaviors across different levels of health literacy among people with T2D will guide the development of effective interventions and customized strategies to enhance medication adherence. Objectives: (1) To examine whether the barriers and facilitators associated with medication adherence differ among people with T2D across different levels of health literacy. (2) To explore patients' perceptions of the barriers and facilitators of medication adherence across different levels of health literacy. (3) To understand how the qualitative interview data complement the quantitative survey results about the barriers and facilitators of medication adherence. Methods: This mixed-methods study used an explanatory sequential design, including a quantitative study with a survey questionnaire followed by a qualitative study with semi-structured interviews. The Health Literacy Pathway Model was used to identify the psychosocial and communication factors that may influence medication adherence. The target population was patients who were 20 years of age or above, were diagnosed with T2D, understood English, and were prescribed at least one oral diabetes medicine daily. Analysis of covariance and direct content analysis were used respectively in quantitative and qualitative analysis. A joint display was used to present the integrated findings from quantitative and qualitative data. Results: In the quantitative phase, 205 participants provided complete information in the survey questionnaire. In the qualitative phase, 23 participants completed semi-structured interviews. Confirmed by quantitative and qualitative data, holding stronger self-efficacy, having fewer concern beliefs about medication, and possessing fewer perceived barriers to medication-taking are necessary for better medication adherence. Linking medication-taking to daily routine and focusing on the internal locus of control is an imperative approach to foster self-efficacy of medication use. Addressing patients' life experience and clarifying medication misinformation may help participants cope with their concerns with medications. Solving the high cost of medications and therapy-related problems could lessen participants' perception of barriers to medication-taking. Conclusion: To optimally support patients' diabetes care, practitioners should address concern beliefs among non-adherent patients with low health literacy, as well as emphasize self-efficacy and perceived barriers to medication adherence among all non-adherent patients with T2D.

Book Investigating Medication Adherence Among Patients with Diabetes Using a Mixed methods Approach

Download or read book Investigating Medication Adherence Among Patients with Diabetes Using a Mixed methods Approach written by Myriam Jihad Jaam and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Medication-taking behavior can significantly affect a patient's health outcomes. Thus, understanding the extent of and barriers to medication adherence are important in informing development of appropriate interventions to ultimately improve patients' health outcomes. The use of mixed-methods research designs in pharmacy practice and health services research has grown steadily in the last decade. Within this case study, we will share our experience of using a convergent mixed-methods design to investigate the extent of and barriers associated with medication nonadherence in Qatari primary care settings among patients with type-2 diabetes mellitus. Briefly, we captured quantitative data (prevalence of nonadherence and associated factors) using a validated questionnaire, and qualitative data (barriers to medication adherence) using one-to-one interviews with patients and health care providers. This case study also discusses the challenges encountered and practical lessons learned relevant to this experience.

Book Medication Adherence for Type 2 Diabetes and Intervention that Can Improve Compliance

Download or read book Medication Adherence for Type 2 Diabetes and Intervention that Can Improve Compliance written by Adebisi Lawrence and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many people around the world that are diagnosed with Type 2 Diabetes Mellitus. Many co-morbidities are associated with the diagnosis of type 2 DM such as coronary artery disease, myocardial infarction, obesity, and hyperlipidemia. Research has proven that it has been difficulty in determining patients who have non-purposeful adherence in taking multiple medications which leads to deficient management of disease (Cheng, Chi-Chen, and Chin-Sia, 2013. Also, research has shown that medication adherence is not something that can be forced upon a patient, because patients can continually be resistant to methods (Cheng, et. al, 2013). Although, a patient cannot be forced to adhere to their medication regimen, healthcare professionals can make sure that the patients make an educated decision. If healthcare providers assist patients with making an accurate decision when making decisions related to their healthcare and comply with their medication, management of DM will be better. The manner in which this assists is that it provides more information on this topic and improves education techniques that can be more comprehendible.

Book Patient Perspectives on Enhancing Type 2 Diabetes Health Literacy

Download or read book Patient Perspectives on Enhancing Type 2 Diabetes Health Literacy written by Tera Kane and published by . This book was released on 2009 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study explores patient perspectives about healthcare providers' effects on health literacy and type 2 diabetes (T2D) from patients' perspectives. As a result, the study gives specific communication and pedagogical strategies that healthcare providers can consider when teaching their patients how to manage their illness. Researchers interviewed or held focus groups with a total of 42 individuals living with T2D. All interviews and focus groups were recorded, transcribed verbatim, and analyzed using constant comparative qualitative techniques. The study shows that, according to patients, providers can both direct and facilitate T2D health literacy development in a number of ways including explaining T2D and how to manage it, considering the context of those explanations, tailoring T2D-related messages to individual patients, providing additional T2D educational resources, and following up with patients. This study extends current literature on patient-provider communication and health literacy by using patients' perspectives to identify specific strategies that healthcare providers can employ in their practices.

Book The Impact of Health Literacy on Self care Activities Among Underserved Patients with Type 2 Diabetes

Download or read book The Impact of Health Literacy on Self care Activities Among Underserved Patients with Type 2 Diabetes written by Nicole Streuding Murry and published by . This book was released on 2018 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: To maintain good health, patients with Type 2 diabetes (T2DM) must perform self-care activities (SCA), many of which require health literacy – the ability to obtain, find, and use healthcare information to make decisions about health. In this dissertation, using the information-motivation-behavioral skills theoretical framework, I assess and examine health literacy in relation to SCA among underserved people with T2DM. This descriptive correlational study is a secondary analysis of data from a larger study of participants from six federally qualified health centers in an urban county in South Central Texas. The sample comprised 388 patients with T2DM (261 English-speaking, 127 Spanish-speaking; 53±10.33 years old), with the majority reporting an annual income of less than $10,000. Functional health literacy was measured with the Newest Vital Sign screening tool; diabetes-specific oral health literacy, with the DM-REALM – a modification of the original REALM instrument. Only 18.3% of participants exhibited adequate functional health literacy; 10.4%, adequate oral health literacy. In bivariate analysis, functional health literacy was related to age, gender, language, acculturation, income, education, and marital status. Oral health literacy was related to gender, employment status, and type of insurance. Significant predictors of functional health literacy included gender, education, and type of insurance. Significant predictors of oral health literacy included gender, employment status, and years with T2DM. In bivariate analysis, diabetes self-efficacy and health information-seeking behaviors were related to diabetes SCA. In hierarchical multiple regression, functional health literacy, health information-seeking behaviors, and diabetes self-efficacy were significant predictors of diabetes SCA. Although health literacy did not exhibit a significant direct effect on diabetes SCA, health information-seeking behaviors mediated the relationship between oral health literacy and diabetes SCA. These findings add to previous findings showing the high prevalence of limited health literacy among underserved people and the negative influence of limited health literacy on SCA among people with T2DM. Further studies of the impact of limited health literacy on diabetes SCA in diverse, underserved populations of people with T2DM are warranted. Future health literacy interventions should incorporate individual- and systems-level approaches in addressing promotion of diabetes SCA

Book Evaluating the Utilization of a Combination Therapy to Improve Self efficacy and Glycemic Control in Patients with Type Two Diabetes Mellitus and Low Health Literacy

Download or read book Evaluating the Utilization of a Combination Therapy to Improve Self efficacy and Glycemic Control in Patients with Type Two Diabetes Mellitus and Low Health Literacy written by Crystal Manus Masling and published by . This book was released on 2020 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Type 2 diabetes mellitus is a significant health issue, as it requires patients to perform daily self-management activities. One in every three Americans with Type 2 diabetes has limited or low health literacy skills. Limited or low health literacy skills can impact a patient’s overall health outcome; therefore, a critical element for disease management and patient adherence is health literacy. The purpose of this three-month scholarly project was to determine if the utilization of an educational intervention specific to one’s level of health literacy, combined with a short message service reinforcement tool, could improve glycemic control and self-efficacy in Type 2 diabetes mellitus patients with limited and low HL. A sample of four participants was recruited for this scholarly project. Participants completed pre and post self-efficacy and health literacy questionnaires. During the three-month intervention phase, participants interacted with the project leader utilizing the text messaging reinforcement tool. After the three-month intervention phase, participants had an overall 9% increase in self-efficacy confidence, a 42% overall increase in health literacy knowledge, and an overall HbA1c mean value reduction of 0.5%. This combination therapy intervention is easy and convenient for health care providers and Type 2 diabetes mellitus patients with limited or low health literacy. This intervention is an efficient and effective method to improve patients self-efficacy and diabetes knowledge; furthermore, this method improves patient self-management skills, glycemic control, and patient longevity.

Book Implementation of Text Message to Successful Type 2 Diabetes  T2D  Management  an Evidence based Practise Project Change Intervention to Improve Medication Adherence Among Type 2 Diabetes  T2D  Patients

Download or read book Implementation of Text Message to Successful Type 2 Diabetes T2D Management an Evidence based Practise Project Change Intervention to Improve Medication Adherence Among Type 2 Diabetes T2D Patients written by Aime̹e Branch and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Background: Type 2 Diabetes (T2D) is a prevalent health care condition, affecting many people across the world. Despite the severity of this health condition, medication non-adherence among T2D patients has remained high, hindering them from achieving blood sugar control and desired health outcomes. Aim: To implement text messaging as an Evidence-based Intervention (EBI) to improve medication adherence and blood sugar control among T2D patients. Methods: Fifty T2D patients aged 18 years and above who had been identified as non-compliant, were engaged in the project for a period of 10 weeks. Participants' demographic information was collected using demographic survey forms. The initial step of the project involved the PM performing pretests for blood glucose. Later, blood glucose tests were performed at week 6 and week 10. Throughout the project, the participants were reminded through text messaging to take their medication, eat balanced meals, exercise, check their blood sugars, ask them how they are feeling, check their feet, remind them about clinical checks, ask them if they are feeling jittery and record blood sugar in the logs. Changes in blood sugar levels at weeks 6 and 10 were analyzed by PM. Findings: Thirty-four percent and 60% of the participants recorded improved blood sugar levels at weeks 6 and 10 respectively indicating that text message intervention at the end of the project was effective. The intervention exceeded the 50% benchmark at week 10. Implications: Text message intervention should be implemented as an evidence-based intervention to improve medication adherence among T2D patients. Nonetheless, there is a need to integrate the intervention with other interventions for more improvements in medication adherence. Keywords: medication adherence, text message intervention, Type 2 Diabetes, Blood Glucose Level " -- Abstract

Book The Association of Health Literacy with the Management of Type 2 Diabetes

Download or read book The Association of Health Literacy with the Management of Type 2 Diabetes written by Samita Kumar and published by . This book was released on 2018 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Type 2 Diabetes (T2D) is a chronic metabolic disease characterized by high blood glucose levels in the blood. It is associated with microvascular and macrovascular complications which can lead to potential threats such as to amputations and even death. The irony of the disease is that these complications are preventable with appropriate treatment and self-management. The Emergency Medicine Department (ED) at University of Southwestern Medical center conducted this study to assess health literacy Parkland Memorial Hospital patients with T2D. The objective for the research study was to assess the for association of health literacy with management of T2D. Methods: This was a prospective study with collection of personal health information (PHI) and 30 day-follow up for ED recidivism. Eligibility was assessed by pre-screening via EPIC (Electronic Medical Record System for Parkland). The tool for measuring health literacy was the Short Assessment of Health Literacy (SAHL) and data was collected. Results: The total number of subjects enrolled was 23 with ages 18 or above male and females both with Spanish or English speaking only with T2D. Mean age of the subjects was ~50 years with standard deviation of 10 years, males were over half than women. About 74% were white hispanic males. According to the data collected, 30% of the patients demonstrated inadequate health literacy based on SAHL score survey. Since the study could not reach adequate power due to low enrollment, no significant associations could be made from this small sample size. Total number of subjects required to have adequate power was 400. Conclusions: Due to low enrollment period at this time the recommendation would be to continue collecting data to have a larger sample size to afford the observation of statistically relevant associations. If any, statistically significant associations are found, then future studies will focus on improving diabetes outcomes through the development of educational tools at the individual patient’s appropriate literacy level. There are many reasons to improve diabetes care and explore all possible factors that contribute to poor outcomes. Millions of people are living with uncontrolled diabetes and the burden is not only on the patient but also on the community as a whole. Quality care should aim for improved benchmarks for patients with diabetes and their knowledge about the disease, such as 1) obtaining HbA1c levels below 8%, 2) blood pressure in the normal range, 3) having regular foot exams to keep a check on any developing signs of pressure sores and 4) most importantly having dilated eye exam on a regular basis.

Book Role of Patients  Perception of Barriers to Taking Medication on Medication Adherence Among Patients with Diabetes

Download or read book Role of Patients Perception of Barriers to Taking Medication on Medication Adherence Among Patients with Diabetes written by Mwangi James Murage and published by . This book was released on 2014 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction Medication adherence remains a problem among Type-2 diabetes (T2D) patients despite availability of effective treatments. Three analyses of extant data sets were conducted to examine barriers to using medication as prescribed as an alternate method to assess medication adherence: 1) development and psychometric evaluation of the Murage-Marrero-Monahan-Medication barriers (4M) scale to assess patients' perceived barriers; 2) patient demographic factors associated with barriers to using medication as prescribed, and 3) the association between patients' perceived barriers to medication use and cardiovascular disease (CVD) risk factor control. Methods Twelve focus groups and a cross-sectional study of 362 T2D patients contributed to develop and evaluate psychometric properties of the 4M scale. A cross-sectional survey of 964 T2D patients was used for the other two studies. Analysis of covariance identified demographic factors associated with reported barriers. Multivariable logistic regression was used to identify barriers associated with CVD risk factors (glucose, blood pressure and lipids) categorized as either poor or good control. Results Exploratory factor analysis with Varimax rotation resulted in a 19-item 4M scale with acceptable psychometric properties. As a five-domain (or single-domain) structure, coefficient alpha ranged from 0.70 to 0.83 (0.92). Both structures demonstrated discriminant validity and known-group validity. Age was inversely associated with all identified barriers while income was inversely associated with poor communication with providers and side effects. A unit increase in the overall barrier mean score on the 4M scale was associated with 92% increase in the odds of having poor control of two or more CVD risk factors compared to good control of all three risk factors (adjusted OR=1.92, 95% CI: 1.16 - 3.17; p

Book Culturally Tailored Education for Improvement in Health Literacy in Hispanics with T2DM

Download or read book Culturally Tailored Education for Improvement in Health Literacy in Hispanics with T2DM written by Lisa Castillo and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diabetes is a complex disease requiring detailed and comprehensive education for patients to successfully manage their disease. This study will explore the problem of low health literacy in the Hispanic population diagnosed with Type 2 Diabetes (T2DM). It will explain why culturally tailored education is so important for the advanced practice nurse to implement into the treatment regimen of this specific patient population. The aim of this grant proposal research is to determine if implementing culturally tailored education into the treatment regimen of Hispanics with T2DM increases their health literacy. Increased health literacy has the potential to increase patient outcomes regarding their diagnosis and disease. A repeated measures randomized control group design will be used for this study. Health literacy and hemoglobin A1c will be measured pre intervention and 12-weeks post intervention. It is hypothesized that Hispanic patients with T2DM will have a statistically significant improvement in health literacy and A1c levels after receiving culturally tailored education regarding their diagnosis as compared to Hispanic patients with T2DM that only receive the standard education regarding their diagnosis.

Book The Importance of Health Literacy Related to Medications Instructions to Promote Adherence in People Living with Cardiovascular Diseases at Rural Settings

Download or read book The Importance of Health Literacy Related to Medications Instructions to Promote Adherence in People Living with Cardiovascular Diseases at Rural Settings written by Tebogo Maria Mothiba and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Health literacy related to prescribed medications instructions is the ability to read, understand and carry out medication instructions as directed. Being generally literate does not automatically make one to be health literate. In most cases, a person,Äôs health literacy is overlooked based on their good general literacy. A convergent parallel mixed method design was used to explore and describe the practices of diabetes mellitus patients regarding prescribed medications instructions. The results showed failure to interpret medications instructions which leads to non-adherence unaware. On the other hand, non-adherence led to complications. Enhancing health literacy includes explanation of the medication instructions in details including the exact times for medication consumption. This could be achieved through peer teaching, health talks with patients and workshops.

Book Patient Diabetes Education in the Management of Adult Type 2 Diabetes

Download or read book Patient Diabetes Education in the Management of Adult Type 2 Diabetes written by Paula Corabian and published by . This book was released on 2001 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a systematic review and critical appraisal of the literature on the use of formal outpatient diabetes education as a therapeutic tool for self-management in the adult patients with type 2 diabetes. Formal patient diabetes education to promote self-management (PDE) at different levels of complexity and comprehensiveness has emerged from instructions by physicians, nurses, and dieticians in physicianþs offices and hospitals. Since 1990 there has been a shift from traditional approaches of PDE to focus on patient-centered perspectives, self-efficacy, self-management and empowerment issuses. Quantitatives research on the use of formal PDE as a therapeutic tool promote self-management in adults with type 2 diabetes has produced mixed results in terms of improved metabolic control and reduced risks for cardiovascular disease. The long-term diabetes control outcomes of formal PDE when used to promote self-management in adults with type 2 diabetes have yet to be established. Further investigations are needed to determine which types of programs or what components are most effective in improving the ability of adults with type 2 diabetes to self-manage their disease; or which category of patients might benefit most. Findnings from qualitative research studies helped to better understand the context in which formal PDE should be applied to be successful in promoting self-managemenet behaviors in adults with type 2 diabetes.
