Presenting time-based risks of stroke and death for Patients facing carotid stenosis treatment options: Patients prefer pie charts over icon arrays

Decision aids for patients with carotid stenosis

BACKGROUND

Shared decision-making tools have been underused by clinicians in real-world practice. Changes to the National Coverage Determination by Medicare for carotid stenting greatly expand the coverage for patients, but simultaneously require a shared decision-making interaction that involves the use of a validated tool. Accordingly, our objective was to evaluate the currently available decision aids for carotid stenosis.

METHODS

We conducted a review of the literature for published work on decision aids for the treatment of carotid disease.

RESULTS

Four publications met inclusion criteria. We found the format of the decision aid impacted patient comprehension and decision making, although patient characteristics also played a role in the therapeutic decisions made. Notably, none of the available decision aids included the widely adopted transcarotid artery revascularization as an option.

CONCLUSIONS

Further work is needed in the development of a widespread validated decision aid instrument for patients with carotid stenosis.

Community engagement in the development of health-related data visualizations: a scoping review

OBJECTIVE

This scoping review aims to address a gap in the literature on community engagement in developing data visualizations intended to improve population health. The review objectives are to: (1) synthesize literature on the types of community engagement activities conducted by researchers working with community partners and (2) characterize instances of "creative data literacy" within data visualizations developed in community-researcher partnerships.

METHODS

Using the 2018 PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines, the review focuses on peer-reviewed journal articles from 2010 to 2022 in PubMed, Web of Science, and Google Scholar. A community engagement tool was applied to the studies by independent reviewers to classify levels of community engagement, social determinants, and vulnerable populations.

RESULTS

Twenty-seven articles were included in the scoping review. Twelve articles worked with vulnerable populations. Four articles attempted to alleviate barriers to representation in their respective studies, with addressing language barriers being the most prevalent approach. Thirteen articles considered social determinants of health. Sixteen studies engaged in iterative approaches with intended users when developing the visualization or tool.

DISCUSSION

Only a few significant examples of creative data literacy are incorporated in the studies. We recommend a specific focus on engaging intended users at every step of the development process, addressing language and cultural differences, and empowering intended users as data storytellers.

CONCLUSIONS

There is room for deeper and more meaningful community involvement in the development of health-related data visualizations geared towards them.

A Rectal Cancer Surgical Decision Aid Is Not Enough: A Qualitative Study

BACKGROUND

Rectal cancer patients often face complex surgical treatment decisions, but there are few available tools to aid in decision-making.

OBJECTIVE

We aimed to identify content and delivery preferences of rectal cancer patients and colorectal surgeons to guide future surgical decision aid creation.

DESIGN

Qualitative study: inductive thematic analysis of semi-structured interviews.

SETTING

In-person and phone interviews.

PATIENTS

We purposively sampled 15 rectal cancer survivors based on demographics and surgery type. Five caregivers also participated. We purposively selected 10 surgeons based on practice type and years of experience.

INTERVENTIONS

Semi-structured interviews.

MAIN OUTCOME MEASURES

Major and minor themes for survivors and surgeons with thematic saturation.

RESULTS

Interviews were a median of 61 minutes (41-93) for patients and 35 minutes (25-59) for surgeons. Nine survivors were younger than 65 years; 7 were female. Surgeons had been practicing for a mean of 10 years (SD 7.4), with 7 in academic and 3 in private settings. Participating survivors and surgeons wanted a comprehensive educational tool-not just a surgical decision aid. Survivors wanted more information on rectal cancer basics and lifestyle, care timelines, and resources during treatment. Surgeons thought patients mostly desired information about surgical options and bowel function. Both patients and surgeons wanted a tool that was personalized, simple, understandable, visually appealing, interactive, short, and in multiple formats.

LIMITATIONS

Results may not be generalizable due to selection bias of participants.

CONCLUSION

Rectal cancer survivors, their caregivers, and colorectal surgeons wanted an educational support tool that would address substantial educational needs through the continuum of disease rather than a surgical decision aid focusing on a discrete surgical choice only.

UNA AYUDA PARA LA DECISIN QUIRRGICA DEL CNCER DE RECTO NO ES SUFICIENTE UN ESTUDIO CUALITATIVO

ANTECEDENTES:Los pacientes con cáncer de recto a menudo enfrentan decisiones de tratamiento quirúrgico complejas, pero hay pocas herramientas disponibles para ayudar en la toma de decisiones.OBJETIVO:Nuestro objetivo fue identificar el contenido y las preferencias de entrega de los pacientes con cáncer de recto y los cirujanos colorrectales para guiar la futura creación de ayuda para la toma de decisiones quirúrgicas.DISEÑO:Estudio cualitativo: análisis temático inductivo de entrevistas semiestructuradas.ESCENARIO:Entrevistas en persona y por teléfono.PACIENTES:Tomamos muestras intencionalmente de 15 sobrevivientes de cáncer de recto, según la demografía y el tipo de cirugía. También participaron cinco cuidadores. Seleccionamos intencionalmente a 10 cirujanos según el tipo de práctica y los años de experiencia.INTERVENCIONES:Entrevistas semiestructuradas.PRINCIPALES MEDIDAS DE RESULTADO:Temas principales y secundarios para sobrevivientes y cirujanos con saturación temática.RESULTADOS:Las entrevistas tuvieron una mediana de 61 minutos (41-93) para pacientes y 35 minutos (25-59) para cirujanos. Nueve sobrevivientes tenían menos de 65 años; siete eran mujeres. Los cirujanos habían estado ejerciendo una media de 10 años (DE 7,4), con siete en entornos académicos y 3 en entornos privados. Los sobrevivientes y cirujanos participantes querían una herramienta educativa comprensible, no solo una ayuda para la decisión quirúrgica. Los sobrevivientes querían más información sobre los conceptos básicos y el estilo de vida del cáncer de recto, los plazos de atención y los recursos durante el tratamiento. Los cirujanos pensaron que los pacientes en su mayoría deseaban información sobre las opciones quirúrgicas y la función intestinal. Tanto los pacientes como los cirujanos querían una herramienta que fuera personalizada, simple, comprensible, visualmente atractiva, interactiva, corta y en múltiples formatos.LIMITACIONES:Los resultados pueden no ser generalizables debido al sesgo de selección de los participantes.CONCLUSIÓN:Los sobrevivientes de cáncer rectal, sus cuidadores y los cirujanos colorrectales querían una herramienta de apoyo educativo que cubriera las necesidades educativas sustanciales a lo largo del tratamiento de la enfermedad en lugar de una ayuda para la decisión quirúrgica que se centre solo en una opción quirúrgica discreta.

Comparing the impact of an icon array versus a bar graph on preference and understanding of risk information: Results from an online, randomized study

BACKGROUND

Few studies have examined the best way to convey the probability of serious events occurring in the future (i.e., risk of stroke or death) to persons with low numeracy or graph literacy proficiency. To address this gap, we developed and user-tested a bar graph and compared it to icon arrays to assess its impact on understanding and preference for viewing risk information.

OBJECTIVES

To determine the: (i) formats' impact on participants' understanding of risk information; (ii) formats' impact on understanding and format preference across numeracy and graph literacy subgroups; (iii) rationale supporting participants' preference for each graphical display format.

METHODS

An online sample (evenly made up of participants with high and low objective numeracy and graph literacy) was randomized to view either the icon array or the bar graph. Each format conveyed the risk of major stroke and death five years after choosing surgery, a stent, or medication to treat carotid artery stenosis. Participants answered questions to assess their understanding of the risk information. Lastly, both formats were presented in parallel, and participants were asked to identify their preferred format to view risk information and explain their preference.

RESULTS

Of the 407 participants, 197 were assigned the icon array and 210 the bar graph. Understanding of risk information and format preference did not differ significantly between the two trial arms, irrespective of numeracy and graph literacy proficiency. High numeracy and graph literacy proficiency was associated with high understanding (p<0.01) and a preference for the bar graph (p = 0.01).

CONCLUSION

We found no evidence to demonstrate the superiority of one format over another on understanding. The majority of participants preferred viewing the risk information using the bar graph format.

Graph literacy matters: Examining the association between graph literacy, health literacy, and numeracy in a Medicaid eligible population

OBJECTIVES

Graphic display formats are often used to enhance health information. Yet limited attention has been paid to graph literacy in people of lower education and lower socioeconomic status (SES). This study aimed to: 1) examine the relationship between graph literacy, numeracy, health literacy and sociodemographic characteristics in a Medicaid-eligible population 2) determine the impact of graph literacy on comprehension and preference for different visual formats.

METHODS

We conducted a cross-sectional online survey among people in the US on Medicaid, and of presumed lower education and SES.

RESULTS

The mean graph literacy score among 436 participants was 1.47 (SD 1.05, range: 0 to 4). Only graph literacy was significantly associated with overall comprehension (p < .001). Mean comprehension scores were highest for the table format (1.91), closely followed by bar graph (1.85) and icon array (1.80). Information comprehension was aligned with preference scores.

CONCLUSIONS

Graph literacy in a Medicaid-eligible population was lower than previous estimates in the US. Tables were better understood, with icon arrays yielding the lowest score. Preferences aligned with comprehension.

PRACTICE IMPLICATIONS

It may be necessary to reconsider the use of graphic display formats when designing information for people with lower educational levels. Further research is needed.
