Literature Review of Type 2 Diabetes Management and Health Literacy

Health literacy and tuberculosis control: systematic review and meta-analysis

Objective

To identify literature on health literacy levels and examine its association with tuberculosis treatment adherence and treatment outcomes.

Methods

Two authors independently searched Pubmed®, Embase, CINAHL, PsycINFO, Scopus, LILACS, Global Health Medicus and ScienceDirect for articles reporting on health literacy levels and tuberculosis that were published between January 2000 and September 2023. We defined limited health literacy as a person's inability to understand, process, and make decisions from information obtained concerning their own health. Methodological quality and the risk of bias was assessed using the JBI critical appraisal tools. We used a random effects model to assess the pooled proportion of limited health literacy, the association between health literacy and treatment adherence, and the relationship between health literacy and tuberculosis-related knowledge.

Findings

Among 5813 records reviewed, 22 studies met the inclusion criteria. The meta-analysis revealed that 51.2% (95% confidence interval, CI: 48.0-54.3) of tuberculosis patients exhibit limited health literacy. Based on four studies, patients with lower health literacy levels were less likely to adhere to tuberculosis treatment regimens (pooled odds ratio: 1.95; 95% CI: 1.37-2.78). Three studies showed a significant relationship between low health literacy and inadequate knowledge about tuberculosis (pooled correlation coefficient: 0.79; 95% CI: 0.32-0.94).

Conclusion

Health literacy is associated with tuberculosis treatment adherence and care quality. Lower health literacy might hamper patients' ability to follow treatment protocols. Improving health literacy is crucial for enhancing treatment outcomes and is a key strategy in the fight against tuberculosis.

Health behaviors according to the ability to understand health information in Korean adults

This study aimed to verify the relationship between the level of understanding of health information and health behaviors among Korean adults. In total, 228 984 adults who participated in the 2021 Korea Community Health Survey were included. Participants were divided into three groups according to age (19-44, 45-64 and 65+). The ability to understand verbal and written health information was included, and its association with health behaviors, including smoking, alcohol consumption and preventive health service uptake, was assessed. Associations between the ability to understand health information and health behaviors were analyzed using chi-squared tests and multiple logistic regression analyses. Approximately 22.7% and 20% of the participants responded that verbal and written health information were easy to understand, respectively, with significant differences by age group. Compared to those with easy-to-understand verbal health information, those with difficulty in understanding had a higher risk of current cigarette smoking and monthly drinking and were less likely to engage in more than moderate physical activity, walking, influenza vaccination in 1 year, cancer examination in 2 years and medical examination in 2 years. Difficulty in understanding or no interest in written health information was also associated with unhealthy behaviors. A strong ability to understand health information is related to positive health behaviors. However, there are differences in the associations by age group, which should be considered when establishing a health literacy improvement strategy. These findings could promote health literacy and ultimately contribute to helping individuals make better choices for positive health behaviors.

Knowledge Assessment During the Medication Process Use by Older Patients on Clinical Routine: A Pilot Study

Objectives

The consumption of medicines has been increasing over the last decades. The lack of medication knowledge (MK) may affect the process of medication use and, consequently, may lead to negative health outcomes. This study carried out a pilot study using a new tool to assess MK in older patients in a daily clinical practice.

Materials and Methods

An exploratory cross-sectional study was conducted, including older patients (≥65 years), taking two or more medicines, followed in a regional clinic. Data were collected during a structured interview, which included an algorithm for assessing MK regarding the identification of the medicines and its use and storage conditions. Health literacy and treatment adherence were also assessed.

Results

The study enrolled 49 patients, mainly between 65 and 75 years (n: 33; 67.3%) and polymedicated (n: 40; 81.6%), taking a mean of 6.9 ± 2.8 medicines per day. A lack of MK (score <50%) was observed in 15 (30.6%) participant patients. "Drug strength" and "storage conditions" were the items which presented the lowest score. MK was positively correlated with higher scores for health literacy and treatment adherence. Younger patients (age <65 years old) also had a higher MK score.

Conclusion

This study showed that the applied tool could evaluate the MK of the participants and identified specific gaps regarding MK within the process of medicine use. Further studies, with more participants, will allow the confirmation of these findings and will stimulate the development of specific strategies to improve MK, thus contributing to better health outcomes.

Effectiveness of synchronous teleconsultation for patients with type 2 diabetes mellitus: a systematic review and meta-analysis

The popularity of teleconsultation during the COVID-19 pandemic enabled increased accessibility for individuals with type 2 diabetes mellitus (T2DM). However, previous studies did not distinguish between synchronous and asynchronous teleconsultation. We evaluated the effectiveness of synchronous teleconsultation for patients with T2DM. We searched Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Library and Cochrane Database of Systematic Reviews, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform databases from inception to July 2021. All included studies were randomized controlled trials of synchronous teleconsultation for adults with T2DM compared with usual care. Reviewers independently extracted data and used the Cochrane tool to evaluate risk of bias. Meta-analyses were conducted using random-effects models. A pooled mean difference for both HbA1c (%) and body mass index (BMI) (kg/m²), systolic blood pressure (SBP) (mm Hg), diastolic blood pressure (DBP) (mm Hg), and low density lipoprotein cholesterol (LDL-cholesterol) (mg/dL) were calculated. Patient-reported outcomes, such as depression, medication adherence, and quality of life, were also assessed. A total of 9807 abstracts were identified and 27 trials were included. Synchronous teleconsultation significantly resulted in greater decrease in HbA1c compared with usual care group (n=8746, 0.35, 95% CI 0.20 to 0.49, I²=73%, p<0.001). No significant effects on BMI (n=699, 0.08 kg/m², 95% CI -0.54 to 0.69), SBP (n=5512, 1.32 mm Hg, 95% CI -0.09 to 2.73), DBP (n=2898, 0.17 mm Hg, 95% CI -1.18 to 1.52), or LDL-cholesterol (n=5276, 3.21 mg/dL, 95% CI -1.75 to 8.17) were found. The effect of teleconsultation in improving patient-reported outcomes was uncertain. Thus, synchronous teleconsultation could be an alternative to usual care. Systematic review registration is PROSPERO CRD42021267019.

Health literacy and cardiovascular disease prevention: a systematic scoping review protocol

INTRODUCTION

Health literacy is 'The skills and resources of a person to access, understand and use information to make decisions, and take action on their own health and healthcare'. Literature investigating cardiovascular disease (CVD) prevention and health literacy often exist in silos, only exploring one element of prevention. This protocol aims to establish a scoping method of articles investigating health literacy and CVD preventive practices or knowledge in lay populations.

METHODS AND ANALYSIS

A scoping review was deemed the most appropriate study design. The topic was conceptualised, with preliminary searching informing subsequent development of search strings. A search of the following databases will be conducted on 31 January 2022: MEDLINE, Global Health, PubMed, Embase, PsycINFO and CINAHL. Studies included will be published in English, of appropriate design, measuring health literacy and some aspect of primary CVD prevention in lay-populations. These criteria will be tested against 25 'pilot' articles from the results, undergoing necessary review before screening commences. A secondary author will screen 10% of abstracts, with a third subject-matter expert reviewing conflicts.

ETHICS AND DISSEMINATION

This review will be disseminated through peer-reviewed scholarly networks, most likely including journal publication and conference presentation.

ARTICLE SUMMARY

CVD is the leading cause of death around the world. This paper proposes an exploration of health literacy's relationship with CVD prevention as a whole, contrasting with the more segmented reviews currently published.
