Health literacy and knowledge in a cohort of Australian patients taking warfarin

© 2018, Grupo de Investigacion en Atencion Farmaceutica. All rights reserved. Objectives: To 1) characterise older patients taking warfarin, 2) assess these patients’ level of warfarin knowledge, and 3) describe their strengths and limitations in health literacy, and 4) explore relationships between participants’ characteristics, warfarin knowledge and health literacy. Methods: A warfarin knowledge questionnaire and Health Literacy Questionnaire (HLQ) were administered to older patients (aged >65 years, N=34) taking warfarin in an Australian general practice setting. Results: Key gaps in participant knowledge pertained to the consequences of an international normalized ratio (INR) being below the target INR range and safety issues such as when to seek medical attention. A limitation for participants with a lower level of health literacy was the ability to appraise health information. Patients who needed assistance in completing the HLQs had significantly lower warfarin knowledge scores (p=0.03). Overseas-born participants and those taking 5 or more long-term medications had lower HLQ scores for specific scales (p<0.05). Conclusion: In this study warfarin knowledge gaps and a limitation of health literacy amongst a small sample of older patients were identified. The findings suggest that education and resources may need to be tailored to the needs of older patients taking warfarin and their carers to address these knowledge gaps and limitations in health literacy. Patients who may need greater support include those that need assistance in completing the HLQ, are overseas-born, or are taking 5 or more long-term medications

A participatory research approach in community pharmacy research: The case for video-reflexive ethnography.

Video-reflexive ethnography (VRE) is a qualitative methodology that explores the complex nature of healthcare 'as it really is'. Its collaborative and reflexive process invites stakeholders (e.g. pharmacists and pharmacy support staff) to participate in analysing their everyday work practices as captured on video footage. Through close collaboration with practitioners and attention to their work contexts, VRE may be a useful methodology to engage a time-poor pharmacy workforce in research about themselves, encouraging more practitioner involvement in practice-based research. Aside from research, VRE has also been used effectively as an intervention to facilitate learning and change in healthcare settings, and could be effective in provoking change in otherwise resistant pharmacy environments. Much like traditional ethnographic approaches, VRE researchers have relied on being present 'in the field' to observe, record and make sense of practices with participants. The COVID-19 pandemic however, has introduced restrictions around travel and physical distancing, which has required researchers to contemplate the conduct of VRE 'at a distance', and to imagine new ways in which the methodological 'closeness' to stakeholders and their workplace contexts can be maintained when researchers cannot be on site. In this commentary, we outline the rationale for participatory methods, in the form of VRE, in pharmacy research. We describe the underlying principles of this innovative methodology, and offer examples of how VRE can be used in pharmacy research. Finally, we offer a reflexive account of how we have adapted the method for use in community pharmacy research, to adapt to physical distancing, without sacrificing its methodological principles. This paper offers not only a new methodology to examine the complexity of pharmacy work, but demonstrates also the responsiveness of VRE itself to complexity, and the potential breadth of future research applications in pharmacy both during and beyond the current pandemic

Warfarin use in the elderly: The nurses' perspective

Objective: To explore the barriers to warfarin use from the perspective of nurses working in aged care. Design: A qualitative study, involving a semi-structured group interview, during March-April 2001. Setting and Subjects: Eleven nurses, employed within the catchment of the Northern Sydney Area Health Service, who were involved in the care of elderly warfarinised patients. Main outcome measure: Identification, via thematic analysis, of the main themes underpinning the nursing perspective on warfarin use in this setting, with regard to their perceived role/s, experiences with patients, and potential strategies for managing the therapy. Results: Five main themes were identified: perceived patient attitude toward warfarin; barriers to the use of warfarin; expressed lack of confidence in the processes involved; nurses' role in warfarin use; and strategies to improve warfarin use. Nurses were concerned about warfarin use in the elderly, but felt they had a limited capacity to intervene. Conclusion: Nurses are potentially underutilised as a resource and support for both patients and prescribers, in the management of warfarin therapy

Balancing risk versus benefit: The elderly patient's perspective on warfarin therapy

Warfarin theraphy is underused in the target at-risk elderly population. Clinicians perceive that older patients are reluctant to use this theraphy, however the perspective of patients or their carers has yet to be explored. Objective: To explore in-depth the perspectives of elderly patients and/ or their carers regarding the use of warfarin therapy. Method: A qualitative study, using semi-structured group interviews was undertaken. The audio-taped discussions were transcribed verbatim, then thematically analysed to identify emergent themes. Group discussions were conducted at a major Sydney teaching hospital, over a 2-month period. Individuals aged 65 years or older (and/or their carers) who were using long-term (6 months) warfarin therapy were recruited by voluntary response to study flyers. Results: 17 patients and carers (mean age 77.2 SD=7.5 years) participated in one of two focus groups. Five core themes emerged regarding warfarin therapy: inadequate knowledge and understanding about it, patients/carers variable experience of information provision, cycle of reactions to being on it, issues in its practical management, and the spectrum of experiences with it. Overall, participants were very accepting of the therapy, describing a high level of compliance, despite initial fears and anxieties, and a relative lack of knowledge. Patients felt somewhat abandoned in their management of warfarin due to the lack of ongoing support services in the community, and inadequate information provision. Conclusions: Elderly patients and their carers appear to be quite accepting of warfarin therapy, in contrast to the perceptions of health care professionals. More effort is needed, however, in terms of information provision, particularly in the form of community-based services, to assist patients in the long-term management of warfarin

Management of warfarin in atrial fibrillation: Views of health professionals, older patients and their carers

Objective: To identify the views of health professionals, patients and their carers on strategies to improve the use and management of warfarin in older patients with atrial fibrillation. Design: Qualitative study based on analysis of group interviews. Setting: A major metropolitan teaching hospital, from 1 March to 30 April 2003. Participants: 14 patients (≥ 65 years) with established atrial fibrillation and taking warfarin, three carers, 12 specialists, eight general practitioners, six community pharmacists, nine hospital pharmacists, and 11 nurses volunteered in response to flyers promoting the study. Results: Suggested strategies to improve warfarin management targeted support services for GPs and patients. Hospital-based clinicians felt that dissemination of trial evidence to GPs to support treatment recommendations is required, and that GPs need to enlist allied health professionals in the management of patients taking warfarin. GPs preferred access to practical advice from expert colleagues on the day-to-day management. Patients requested more information about warfarin therapy, as access to information is inadequate, particularly from primary sources (GPs, community pharmacists). Verbal and written information are equally important, but a single counselling session or supply of a booklet was viewed as inadequate. Participants identified various interventions for all levels of warfarin management; from the collective input, a framework for management strategies was developed. Conclusions: Health professionals and patients require more customised information to support warfarin use and management

An mHealth intervention to improve nurses’ atrial fibrillation and anticoagulation knowledge and practice: the EVICOAG study

© The European Society of Cardiology 2018. Background: There is a need to improve cardiovascular nurses’ knowledge and practices related to stroke prevention, atrial fibrillation and anticoagulation therapy. Aims: The aim of this study was to evaluate the efficacy of EVICOAG – a novel mHealth, smartphone-based, spaced-learning intervention on nurses’ knowledge of atrial fibrillation and anticoagulation. Methods: Nurses employed in four clinical specialties (neuroscience, stroke, rehabilitation, cardiology) across three hospitals were invited to participate. In this quasi-experimental study, 12 case-based atrial fibrillation and anticoagulation learning scenarios (hosted by an mHealth platform) were delivered to participants’ smartphones over a 6-week period (July–December 2016) using a spaced timing algorithm. Electronic surveys to assess awareness and knowledge were administered pre (T1) and post (T2) intervention. Results: From 74 participants recruited to T1, 40 completed T2. There was a 54% mean improvement in knowledge levels post-intervention. The largest improvement was achieved in domains related to medication interaction and stroke and bleeding risk assessment. Post-intervention, those who completed T2 were significantly more likely to use CHA 2 DS 2 -VASc (2.5% vs. 37.5%) and HAS-BLED (2.5% vs. 35%) tools to assess stroke and bleeding risk, respectively (P<0.01). Conclusion: The EVICOAG intervention improved nurses’ knowledge of atrial fibrillation and anticoagulation, and influenced their uptake and use of stroke and bleeding risk assessment tools in clinical practice. Future research should focus on whether a similar intervention might improve patient-centred outcomes such as patients’ knowledge of their condition and therapies, medication adherence, time in the therapeutic range and quality of life

Opportunities and challenges to improving antibiotic prescribing practices through a One Health approach: Results of a comparative survey of doctors, dentists and veterinarians in Australia

© 2018 Article author(s). Objectives To explore and compare the knowledge, attitudes and experiences of doctors, dentists and veterinarians (as prescribers) in relation to antibiotic use and antibiotic resistance (AbR), and to consider the implications of these for policy-making that support a One Health approach. Design A cross-sectional survey conducted online. Setting Doctors, dentists and veterinarians practising in primary, secondary or tertiary care in Australia. Participants 547 doctors, 380 dentists and 403 veterinarians completed the survey. Main outcome measures Prescribers' knowledge, attitudes and perceptions of AbR, the extent to which a range of factors are perceived as barriers to appropriate prescribing practices, and perceived helpfulness of potential strategies to improve antibiotic prescribing in practice. Results There was substantial agreement across prescriber groups that action on AbR is required by multiple sectors and stakeholders. However, prescribers externalised responsibility to some extent by seeing the roles of others as more important than their own in relation to AbR. There were common and context-specific barriers to optimal prescribing across the prescriber groups. Prescriber groups generally perceived restrictive policies as unhelpful to supporting appropriate prescribing in their practice. Conclusions The results have implications for implementing a One Health approach that involves doctors, dentists and veterinarians as key players to tackling the crisis of AbR. The findings are that (1) prescribers understand and are likely receptive to a One Health policy approach to AbR, (2) policy development should be sensitive to barriers that are specific to individual prescriber groups and (3) the development and introduction of interventions that might be perceived as reducing prescriber autonomy will need to be carefully designed and implemented

Scholarly publishing depends on peer reviewers

The peer-review crisis is posing a risk to the scholarly peer-reviewed journal system. Journals have to ask many potential peer reviewers to obtain a minimum acceptable number of peers accepting reviewing a manuscript. Several solutions have been suggested to overcome this shortage. From reimbursing for the job, to eliminating pre- publication reviews, one cannot predict which is more dangerous for the future of scholarly publishing. And, why not acknowledging their contribution to the final version of the article published? PubMed created two categories of contributors: authors [AU] and collaborators [IR]. Why not a third category for the peer-reviewer
