The impact of health literacy on psychosocial and behavioural outcomes among people at low risk of cardiovascular disease

How do general practitioners manage patient health literacy differences in cardiovascular disease prevention consultations? An interview study

OBJECTIVES

Low health literacy is associated with worse health outcomes, including for cardiovascular disease (CVD). However, general practitioners (GPs) have limited support to identify and address patient health literacy needs in CVD prevention consultations. This study explored GPs' experiences of patient health literacy needs during CVD risk assessment and management consultations.

METHODS

Semi-structured interviews with 18 GPs in Tasmania, Australia in 2021. A Framework Analysis approach was used to code transcripts to a thematic framework.

RESULTS

GPs perceptions on patient health literacy informed three themes: 1. Methods of estimating health literacy; 2. GPs' perceptions about the impact of health literacy on CVD prevention including risk factor knowledge and behaviours; and 3. Strategies for communicating with patients experiencing health literacy challenges. The findings show that while no formal tools were used to assess health literacy in this sample, perceived health literacy can change GPs' communication and prevention strategies.

CONCLUSION

The findings raise concerns about the equity of choices made available to patients, based on subjective perceptions of their health literacy level.

PRACTICE IMPLICATION

GPs could be better supported to assess and address patient health literacy needs in CVD prevention consultations.

Relationship Between Health Literacy and Unhealthy Lifestyle Behaviours in Older Adults Living in Switzerland: Does Social Connectedness Matter?

Objectives: To investigate the association between health literacy (HL) and unhealthy lifestyle behaviours and to explore the moderating role of social connectedness in this relationship in older adults in Switzerland. Methods: We used data from 1,455 respondents to Wave 8 of the Survey of Health, Ageing, and Retirement in Europe (SHARE). Associations between the number of unhealthy lifestyle behaviours (smoking, risky alcohol consumption, suboptimal daily consumption of fruits/vegetables, lack of vigorous physical activity) and HL were examined using multivariable Poisson regression models, which allowed for interactions between HL and social connectedness to test the moderation hypothesis. Results: Respondents with inadequate HL were significantly more likely to have a higher number of unhealthy lifestyle behaviours than respondents with sufficient HL. We found a stronger positive association between inadequate HL and the number of unhealthy lifestyle behaviours among socially isolated individuals. Conclusion: Greater social connectedness seems to buffer the negative impact of inadequate HL on unhealthy lifestyle behaviours in older adults, highlighting the importance of good HL for healthy lifestyles, especially in individuals with low social reserve.

Decision Support Tools for Coronary Artery Calcium Scoring in the Primary Prevention of Cardiovascular Disease Do Not Meet Health Literacy Needs: A Systematic Environmental Scan and Evaluation

A shared decision-making approach is considered optimal in primary cardiovascular disease (CVD) prevention. Evidence-based patient decision aids can facilitate this but do not always meet patients' health literacy needs. Coronary artery calcium (CAC) scans are increasingly used in addition to traditional cardiovascular risk scores, but the availability of high-quality decision aids to support shared decision-making is unknown. We used an environmental scan methodology to review decision support for CAC scans and assess their suitability for patients with varying health literacy. We systematically searched for freely available web-based decision support tools that included information about CAC scans for primary CVD prevention and were aimed at the public. Eligible materials were independently evaluated using validated tools to assess qualification as a decision aid, understandability, actionability, and readability. We identified 13 eligible materials. Of those, only one qualified as a decision aid, and one item presented quantitative information about the potential harms of CAC scans. None presented quantitative information about both benefits and harms of CAC scans. Mean understandability was 68%, and actionability was 48%. Mean readability (12.8) was much higher than the recommended grade 8 level. Terms used for CAC scans were highly variable. Current materials available to people considering a CAC scan do not meet the criteria to enable informed decision-making, nor do they meet the health literacy needs of the general population. Clinical guidelines, including CAC scans for primary prevention, must be supported by best practice decision aids to support decision-making.
