Solving the information overload problem: a letter from Canada

Virtual reality and augmented reality in the management of intracranial tumors: A review

Neurosurgeons are faced with the challenge of planning, performing, and learning complex surgical procedures. With improvements in computational power and advances in visual and haptic display technologies, augmented and virtual surgical environments can offer potential benefits for tests in a safe and simulated setting, as well as improve management of real-life procedures. This systematic literature review is conducted in order to investigate the roles of such advanced computing technology in neurosurgery subspecialization of intracranial tumor removal. The study would focus on an in-depth discussion on the role of virtual reality and augmented reality in the management of intracranial tumors: the current status, foreseeable challenges, and future developments.

User-Centered Design and Printed Educational Materials: A Focus Group Study of Primary Care Physician Preferences

INTRODUCTION

It is challenging for primary care physicians (PCPs) to review and apply the growing amount of clinical evidence available. Printed educational materials (PEMs), which synthesize evidence, are often ineffective at improving knowledge, possibly due to poor design and limited uptake. In this study, we collected PCP preferences for the design and content of physician-oriented PEMs and determined key attributes that may increase their usability and uptake.

METHODS

We held 90-minute focus groups with PCPs in Toronto, ON, Canada. Focus groups included discussion about whether and how participants use PEMs, feedback on three examples of PEMs, and a discussion on general format and design preferences in PEMs. We analyzed focus group transcripts using a thematic analysis and summarized results in a list of user preferences.

RESULTS

Four focus groups were held with 13 PCPs. We found that participants only read PEMs relevant to their patients and prefer short, concise documents, with links to sources that can provide more detailed information. Simplicity of materials was important, with many participants preferring PEMs without lengthy backgrounds or scientific explanations. Most participants wanted to see key messages highlighted to easily assess the relevance of the materials to their practice. Some participants shared physician-oriented PEMs with patients.

DISCUSSION

This study shows that PCPs may prefer shorter, simpler, and more concise documents that have less scientific detail but provide references to further information sources. It is important to understand end user preferences for the design and content of these materials to enhance their uptake.

Redesigning printed educational materials for primary care physicians: design improvements increase usability

BACKGROUND

Printed educational materials (PEMs) are a frequently used tool to disseminate clinical information and attempt to change behavior within primary care. However, their effect on clinician behavior is limited. In this study, we explored how PEMs can be redesigned to better meet the needs of primary care physicians (PCPs) and whether usability and selection can be increased when design principles and user preferences are used.

METHODS

We redesigned a publicly available PEM using physician preferences, design principles, and graphic designer support. We invited PCPs to select their preferred document between the redesigned and original versions in a discrete choice experiment, followed by an assessment of usability with the System Usability Scale and a think aloud process. We conducted this study in both a controlled and opportunistic setting to determine whether usability testing results vary by study location. Think aloud data was thematically analyzed, and results were interpreted using the Technology Acceptance Model.

RESULTS

One hundred and eighty four PCPs participated in the discrete choice experiment at the 2014 Family Medicine Forum, a large Canadian conference for family physicians. Of these, 87.7 % preferred the redesigned version. Follow-up interviews were held with a randomly selected group of seven participants. We repeated this in a controlled setting in Toronto, Canada, with a set of 14 participants. Using the System Usability Scale, we found that usability scores were significantly increased with the redesign (p < 0.001). We also found that when PCPs were given the choice between the two versions, they selected the redesigned version as their preferred PEM more often than the original (p < 0.001). Results did not appear to differ between the opportunistic and controlled setting. We used the results of the think aloud process to add to a list of end user preferences developed in a previous study.

CONCLUSIONS

We found that redesigning a PEM with user preferences and design principles can improve its usability and result in the PEM being selected more often than the original. We feel this finding supports the involvement of the user, application of design principles, and the assistance of a graphic designer in the development of PEMs.

What criteria do consumer health librarians use to develop library collections? a phenomenological study

OBJECTIVES

The criteria for determining whether resources are included in consumer health library collections are summarized in institutional collection development policies (CDPs). Evidence suggests that CDPs do not adequately capture all of these criteria. The aim of this study was to describe the resource review experience of librarians and compare it to what is described in CDPs.

METHODS

A phenomenological approach was used to explore and describe the process. Four consumer health librarians independently evaluated cancer-related consumer health resources and described their review process during a semi-structured telephone interview. Afterward, these librarians completed online questionnaires about their approaches to collection development. CDPs from participating libraries, interview transcripts, and questionnaire data were analyzed. Researchers summarized the findings, and participating librarians reviewed results for validation.

RESULTS

Librarians all utilized similar criteria, as documented in their CDPs; however, of thirteen criteria described in the study, only four were documented in CDPs.

CONCLUSIONS

CDPs for consumer health libraries may be missing important criteria that are considered integral parts of the collection development process.

IMPLICATIONS

A better understanding of the criteria and contextual factors involved in the collection development process can assist with establishing high-quality consumer health library collections.

Who goes to a library for cancer information in the e-health era? A secondary data analysis of the Health Information National Trends Survey (HINTS)

This study identifies characteristics of Americans who chose the library as their primary cancer information source over the Internet by examining demographic characteristics, online use experience, concerns of information quality, and perceptions of cancer information seeking. A secondary data analysis is conducted using the Health Information National Trends Survey (HINTS) of the National Cancer Institute (NCI). Findings reveal that people who are more likely to choose the library are, compared to their Internet counterparts, people who lack online experience, are distrustful of online cancer information, and are more aware of cancer sources. However, they are not necessarily more adept cancer information seekers and do not have a greater expectation of getting quality information from the library. These findings suggest how the library plays its role as an information source for cancer information consumers in the e-health environment. Implications of the findings are discussed in a way that libraries could invest their efforts to reduce the digital health divide and to advance consumer health information literacy.

Evidence-based practice: an examination of its ramifications for the practice of speech-language pathology

PURPOSE

The purpose of this article is to consider some of the ramifications that arise when a discipline newly endorses evidence-based practice (EBP) as a primary guiding principle. Although EBP may appear straightforward, events experienced by peer disciplines that have preceded us in the implementation of EBP raise questions about defining acceptable forms of evidence for treatment effectiveness and efficacy, the potential roles of nonspecific or common factors, therapist quality in achieving therapy outcomes, and eventual applications of EBP that may overly confine which treatments are considered acceptable and reimbursable.

METHOD

Through narrative review of the literature, the article examines valuable as well as controversial features of EBP in addition to obstacles that may impede the transition of evidence (research findings) to clinical practice.

CONCLUSION

EBP is a valuable construct in ensuring quality of care. However, bridging between research evidence and clinical practice may require us to confront potentially difficult issues and establish thoughtful dialogue about best practices in fostering EBP itself.

Information Literacy for Speech-Language Pathologists: A Key to Evidence-Based Practice

Purpose

In this tutorial, we review the tenets of information literacy (IL) that parallel and intersect with new American Speech-Language-Hearing Association (ASHA) certification standards requiring clinicians to engage in evidence-based practice (EBP).

Method

A review of the literature on EBP in medical and allied health areas was conducted through an online database search. The Information Literacy Competency Standards for Higher Education (American Library Association, 2004) are used as a framework for outlining IL practices that will aid in EBP.

Results

Current strategies are contrasted with more desirable strategies. Potential barriers to the utilization of information-literate procedures in locating sources of reliable clinical evidence are discussed together with potential solutions.

Conclusion

Suggestions for more efficient information searches by clinicians, as well as a proposed discipline-wide agenda for increasing clinicians' IL skills during and after entry-level graduate training, are provided.

Evidence-based practice in stuttering: Some questions to consider

A recent forum in JFD (28/3, 2003) evaluated the status of evidence-based practice in fluency disorders, and offered recommendations for improvement. This article re-evaluates the level of support available for some popular approaches to stuttering therapy and questions the relative value placed on some types of programs endorsed by the forum. Evidence-based practice is discussed within the context of emerging concerns over its application to non-medical interventions and suggestions are made for grounding fluency interventions by reference to empirically supported principles of change. A popular, evidence-based intervention for stuttering in young children (the Lidcombe program) is evaluated within the suggested parameters.

EDUCATIONAL OBJECTIVES

After reading this article, the reader will be able to: (1) evaluate the status of evidence-based practice in fluency disorders; (2) list concerns about the impact of narrow interpretation of EBP on research and practice in the field of fluency disorders and other non-medical domains; (3) articulate the role of theory and basic research in selecting among and evaluating therapy approach options.
