Single dose of budesonide/formoterol turbuhaler compared to salbutamol pMDI for speed of bronchodilator onset in asthma: a randomised cross-over trial.

OBJECTIVE: To compare bronchodilator response after to salbutamol and budesonide/formoterol in adults with stable asthma. METHODS: A double-blind, cross-over, single-centre, placebo-controlled, non-inferiority trial. Adults with stable asthma were randomised to different orders of two treatment regimens: two actuations of placebo via MDI and one actuation of budesonide/formoterol 200/6 µg via turbuhaler; and one actuation of placebo turbuhaler and two actuations of salbutamol 100 µg via MDI. The primary outcome measure was FEV1 after 2 min. Secondary outcome measures included FEV1, mBorg Dyspnoea Scale score and visual analogue score for breathlessness over 30 min. RESULTS: Forty-nine of 50 potential participants were randomised. One participant withdrew following the first intervention visit and another could not be randomised due to COVID-19 restrictions. The mean (SD) change from baseline FEV1 2 min after treatment administration for budesonide/formoterol and salbutamol was 0.08 (0.14) L, n=49, and 0.17 (0.18) L, n=48, respectively, mean (95% CI) paired difference of -0.097 L (-0.147 to -0.047), p=0.07, against a non-inferiority bound of -0.06 L. In the secondary analysis, FEV1 over 30 min was lower for budesonide/formoterol compared with salbutamol, difference (95% CI): -0.10 (-0.12 to -0.08) L, p<0.001. There were no differences in Visual Analogue Scale score or mBorg Dyspnoea Scale score between treatments. CONCLUSION: The results do not support the primary hypothesis of non-inferiority at the boundary of -0.06 L for the difference between budesonide/formoterol 200/6 µg compared with salbutamol 200 µg for FEV1 at 2 min, and could be consistent with inferiority with a p value of 0.07. For the secondary analysis of FEV1 measurements over time, the FEV1 was higher with salbutamol. TRIAL REGISTRATION NUMBER: Australian and New Zealand Clinical Trials Registry (ACTRN 12619001387112).

Estimating the prevalence of drawing in clinical practice among kiwi doctors.

Drawing has played a key role in the development and dissemination of Medicine and Surgery, such as to share anatomy, pathology, and techniques for clinical interventions. While many of the visuals used in medicine today are created by medical illustration professionals, and by imaging techniques such as photography and radiography; many doctors continue to draw routinely in their clinical practice. This is known to be valued by patients, for example when making informed decisions about care. We surveyed doctors in New Zealand online regarding their use of drawing to explore the prevalence of this practice. 472 complete responses were obtained over 3 months. There were very high rates of drawing among responding doctors practicing in both medical and surgical specialties. Reasons for drawing are explored and included professional, collegial, and patient communication, supporting informed consent, clinical documentation, and for planning procedures. Widespread use of drawing in clinical practice, almost non-existent training or support for this in digital workflows, and high interest in resources to develop clinical drawing skills, suggest unmet training needs for this practical clinical communication tool.

How best to share research with study participants? A randomised crossover trial comparing a comic, lay summary, and scientific abstract.

Healthcare research is traditionally published in academic papers, coded in scientific language, and locked behind paywalls - an inaccessible form for many. Sharing research results with participants and the public in an appropriate, accessible manner, is an ethical practice directed in research guidance. Evidence-based recommendations for the medium used are scant, but science communication advice advocates principles which may be fulfilled well by the medium of comics. We report a randomised crossover study conducted online, comparing participant preferences for research results shared in the medium of a comic, a traditional lay text summary, and the control approach of a scientific abstract. 1236 respondents read all three summaries and ranked their most and least preferred formats. For the most preferred summary, the comic was chosen by 716 (57.9%), lay summary by 321 (26.0%), and scientific abstract by 199 (16.1%) respondents. For the least preferred summary the scientific abstract was chosen by 614 (49.7%), lay summary by 380 (30.7%) and comic by 242 (19.6%). Review of free-text responses identified key reasons for the majority preferring the comic over the others, which included finding this easier to read and understand, more enjoyable to consume, and more satisfactory as a medium of communication.

Optimal Asthma Control: Time for a New Target.

The stepwise approach to pharmacological treatment in adult asthma mandates that asthma treatment is progressively stepped up to achieve symptom control and reduce the risk of exacerbations and stepped down after a period of prolonged control. This review proposes that in adults without good asthma control, well-controlled asthma can only be achieved in approximately 70% of patients across the strata of severity, and only if there is a progressive increase in inhaled corticosteroid/long-acting ß2 agonist therapy to a maintenance inhaled corticosteroid dose that causes the same magnitude of systemic side effects as oral prednisone at a 5-mg daily dose. Another consideration is that in a person with asthma, there are numerous overlapping disorders that can present with symptoms indistinguishable from asthma, comorbidities that contribute to poor control and lifestyle/environmental factors that require treatment in their own right and that if specifically managed might lead to better outcomes. The disparity between patients' perceptions and guideline assessment of control may be due to partially controlled asthma being associated with near-maximal levels of quality of life, with minimal impairment. Finally, it is widely assumed that asthma symptom control equates to elimination of risk of asthma attacks, an assumption that may not apply to many patients, particularly those with more severe asthma. We propose that further research be undertaken to determine the optimal levels of asthma control and the potential value of different treatment targets, such as control of type-2 airway inflammation, that can be achieved with currently available treatment, based on efficacy, side effects, and cost.

Engaging Maori with qualitative healthcare research using an animated comic.

This article reports an effective strategy for recruiting patients with asthma to a qualitative study using an animated comic advertised on social media. An ad spend of NZ$432 on Facebook resulted in 101 study enquiries, and 27 participants taking part in the focus groups, of which 16 (56%) were Maori, the Indigenous Peoples of New Zealand. Representation of Maori amongst participants was over five times higher than their proportion in the local population (9.7%), resulting in data fulfilling the principle of equal explanatory power, an approach to research which can help advance Maori health development and address inequity. The success of this campaign is of particular interest for health researchers in New Zealand where Maori continue to be disproportionately affected by poorer health outcomes compared with non-Maori, particularly those with asthma. Approaches that better engage and support participation of under-represented communities in clinical research are of wider global interest. We reflect on the recruitment strategy and outcomes within a Kaupapa Maori framework, explore how this can be applied more widely in healthcare, and suggest direction for future study and implementation. Lay summary We designed an animated comic to advertise a study for patients with asthma. This was shared locally with a Facebook ad. The approach was highly engaging with the public, and resulted in rapid recruitment. Interestingly, participation of Maori (the Indigenous People of New Zealand) was over five times higher than their proportion in the local population. Maori have poorer health outcomes and increased barriers to healthcare access compared with non-Maori, particularly those with asthma. Approaches which can engage and support under-represented communities to participate in clinical research are of wider global interest. In this article, we reflect on the recruitment strategy and outcomes, and suggest direction for future study and implementation.

Public engagement with clinical research on social media; which visual medium works best? A 5-year retrospective analysis.

'Public engagement' describes a collaborative relationship between scientists and the public we serve. This has the potential to improve clinical research and is encouraged by key research funding bodies, however the objective evidence base for effective approaches remains limited. Social media algorithms determine what content users see and are known to weight post media differently. While visual content is understood to improve reach and engagement broadly, less is known about which kinds of visuals are most effective for engaging people with clinical research. We present a five year retrospective analysis of public engagement with Facebook posts made by an independent medical research institute, classified by their visual media content. Inclusion of visual post media was associated with positive effects on both reach and engagement. We present medium and strong evidence that this effect was most pronounced for comics compared to other visual media types. This data evidences objective value of using comics and other visual media for public engagement with clinical research. The metrics evaluated are easily accessible on many social media platforms meaning this approach could readily be applied by other researchers to measure the impact of their public engagement efforts, and inform science communication strategies and resource allocation.

Using comics and curiosity to drive pandemic research on a national scale.

An independent online Public Health survey regarding the COVID-19 pandemic was conducted during an Alert Level 4 lockdown, the highest possible, in New Zealand. An illustrated and curiosity-driven public engagement campaign was designed to advertise survey participation, and performance compared with a standard approach using randomised controlled A/B Split tests. The 'Caretoon' approach featured comic illustrations, appealed to goodwill and was intended to pique curiosity. This linked to an illustrated version of the survey which, upon completion, gave a personalised comic summary showing how respondent's answers compared with national averages. The standard ad and survey were not illustrated with comics, and did not provide a personalised comic summary on completion. Both approaches were cost- and time-effective, together resulting in 18,788 responses over six days. The Caretoon approach outperformed the standard approach in terms of the number of people reached, engaged, survey link clicks, gender and ethnic diversity amongst respondents, and cost-effectiveness of advertising. This came at the expense of a small reduction in the proportion of completed surveys and male respondents. The research evidences objective value of public engagement activity, comics and curiosity as tools which can support Public Health research on a national scale.

The role of comics in public health communication during the COVID-19 pandemic.

As the COVID-19 pandemic sweeps the globe, evolving containment measures have created an unprecedented need for rapid and effective science communication that is able to engage the public in behavioural change on a mass scale. Public health bodies, governments, and media outlets have turned to comics in this time of need and found a natural and capable medium for responding to the challenge. Comics have been used as a vehicle to present science in graphic narratives, harnessing the power of visuals, text, and storytelling in an engaging format. This perspective paper explores the emerging role and research supporting comics as a public health tool during the COVID-19 pandemic.

The art of consent: visual materials help adult patients make informed choices about surgical care.

Supporting patients in making informed healthcare decisions is a cornerstone of ethical medical practice. Surgeons frequently draw for and show images to patients when consenting them for operations but the value of this practice in informed decision-making is unclear. An audit was conducted in a General Surgery Department. 244 patients completed questionnaires on the value of visual materials when giving consent for surgery. The complexity of the operations was classified into "simple", "moderate" or "complex". 100% of patients felt they had given informed consent to surgery. 62% of patients received at least one form of visual material during the consenting process. All patients who received a drawing, and 99% of those provided with other images, valued these resources. Visual materials were considered more useful to patients when giving consent for moderate or complex operations than simple ones. Approximately one third of patients who did not receive visual materials would have appreciated these when making an informed decision. This research highlights the value of surgeons drawing for, and providing other visual resources to, their patients as part of the consent process. There is a role for further research and training materials in drawing skills for surgeons.

Is drawing a valuable skill in surgical practice? 100 surgeons weigh in.

The author noted surgeons frequently drawing in routine practice. Literature review revealed no prior study of this activity. This research was conducted to examine the prevalence, purpose, and perceived value of this practice. Surgeons' experiences and opinions regarding drawing in surgical practice were canvassed via an online survey. One-hundred surgeons participated. 92% valued drawing routinely in practice. Utility was reported across domains of consent, communication, patient care, medico-legal, education, and planning operations. Free-text feedback is discussed, and learning points from this data were summarised. This paper establishes the collective professional opinion of 100 surgeons regarding the value of drawing, which plays a thriving role in current surgical practice. The utility of this skill transcends merely documenting visual information, allowing surgeons to quickly visualise simplified, dynamic representations of reality. This facilitates communication between professionals, and with their patients. The efficiency and availability of this medium allows drawing to maintain a distinct role in medical communication amongst other imaging modalities available. This paper is the first to document the prevalence of drawing amongst surgeons, substantiates an informed professional opinion supporting this practice, and demonstrates widespread enthusiasm for further training in these skills.
