(JMIR Mhealth Uhealth., 2016-01-27) Mercer, Kathryn; Grindrod, Kelly; Schneider, Eric; Li, Melissa; Chilana, Parmit; Giangregorio, Lora M.
Background: Physical inactivity and sedentary behavior increase the risk of chronic illness and death. The newest generation of “wearable” activity trackers offers potential as a multifaceted intervention to help people become more active. Objective: To examine the usability and usefulness of wearable activity trackers for older adults living with chronic illness. Methods: We recruited a purposive sample of 32 participants over the age of 50, who had been previously diagnosed with a chronic illness, including vascular disease, diabetes, arthritis, and osteoporosis. Participants were between 52 and 84 years of age (mean 64); among the study participants, 23 (72%) were women and the mean body mass index was 31 kg/m2 . Participants tested 5 trackers, including a simple pedometer (Sportline or Mio) followed by 4 wearable activity trackers (Fitbit Zip, Misfit Shine, Jawbone Up 24, and Withings Pulse) in random order. Selected devices represented the range of wearable products and features available on the Canadian market in 2014. Participants wore each device for at least 3 days and evaluated it using a questionnaire developed from the Technology Acceptance Model. We used focus groups to explore participant experiences and a thematic analysis approach to data collection and analysis. Results: Our study resulted in 4 themes: (1) adoption within a comfort zone; (2) self-awareness and goal setting; (3) purposes of data tracking; and (4) future of wearable activity trackers as health care devices. Prior to enrolling, few participants were aware of wearable activity trackers. Most also had been asked by a physician to exercise more and cited this as a motivation for testing the devices. None of the participants planned to purchase the simple pedometer after the study, citing poor accuracy and data loss, whereas 73% (N=32) planned to purchase a wearable activity tracker. Preferences varied but 50% felt they would buy a Fitbit and 42% felt they would buy a Misfit, Jawbone, or Withings. The simple pedometer had a mean acceptance score of 56/95 compared with 63 for the Withings, 65 for the Misfit and Jawbone, and 68 for the Fitbit. To improve usability, older users may benefit from devices that have better compatibility with personal computers or less-expensive Android mobile phones and tablets, and have comprehensive paper-based user manuals and apps that interpret user data. Conclusions: For older adults living with chronic illness, wearable activity trackers are perceived as useful and acceptable. New users may need support to both set up the device and learn how to interpret their data.
Behavior Change Techniques Present in Wearable Activity Trackers: A Critical Analysis
(JMIR mHealth and uHealth, 2016-04-27) Mercer, Kathryn; Burns, Catherine; Giangregorio, Lora M.; Li, Melissa; Grindrod, Kelly
Background: Wearable activity trackers are promising as interventions that offer guidance and support for increasing physical activity and health-focused tracking. Most adults do not meet their recommended daily activity guidelines, and wearable fitness trackers are increasingly cited as having great potential to improve the physical activity levels of adults. Objective: The objective of this study was to use the Coventry, Aberdeen, and London-Refined (CALO-RE) taxonomy to examine if the design of wearable activity trackers incorporates behavior change techniques (BCTs). A secondary objective was to critically analyze whether the BCTs present relate to known drivers of behavior change, such as self-efficacy, with the intention of extending applicability to older adults in addition to the overall population. Methods: Wearing each device for a period of 1 week, two independent raters used CALO-RE taxonomy to code the BCTs of the seven wearable activity trackers available in Canada as of March 2014. These included Fitbit Flex, Misfit Shine, Withings Pulse, Jawbone UP24, Spark Activity Tracker by SparkPeople, Nike+ FuelBand SE, and Polar Loop. We calculated interrater reliability using Cohen's kappa. Results: The average number of BCTs identified was 16.3/40. Withings Pulse had the highest number of BCTs and Misfit Shine had the lowest. Most techniques centered around self-monitoring and self-regulation, all of which have been associated with improved physical activity in older adults. Techniques related to planning and providing instructions were scarce. Conclusions: Overall, wearable activity trackers contain several BCTs that have been shown to increase physical activity in older adults. Although more research and development must be done to fully understand the potential of wearables as health interventions, the current wearable trackers offer significant potential with regard to BCTs relevant to uptake by all populations, including older adults.
“My pharmacist”: Creating and maintaining relationship between physicians and pharmacists in primary care settings
(Elsevier, 2020-01) Mercer, Kathryn; Neiterman, Elena; Guirguis, Lisa; Burns, Catherine; Grindrod, Kelly
Background Pharmacists and physicians are being increasingly encouraged to adopt a collaborative approach to patient care, and delivery of health services. Strong collaboration between pharmacists and physicians is known to improve patient safety, however pharmacists have expressed difficulty in developing interprofessional working relationships. There is not a significant body of knowledge around how relationships influence how and when pharmacists and physicians communicate about patient care. Objectives This paper examines how pharmacists and primary care physicians communicate with each other, specifically when they have or do not have an established relationship. Methods Thematic analysis of data from semi-structured interviews with nine primary care physicians and 25 pharmacists, we examined how pharmacists and physicians talk about their roles and responsibilities in primary care and how they build relationships with each other. Results We found that both groups of professionals communicated with each other in relation to the perceived scope of their practice and roles. Three emerging themes emerged in the data focusing on (1) the different ways physicians communicate with pharmacists; (2) insights into barriers discussed by pharmacists; and (3) how relationships shape collaboration and interactions. Pharmacists were also responsible for initiating the relationship as they relied on it more than the physicians. The presence or absence of a personal connection dramatically impacts how comfortable healthcare professionals are with collaboration around care. Conclusion The findings support and extend the existing literature on pharmacist-physician collaboration, as it relates to trust, relationship, and role. The importance of strong communication is noted, as is the necessity of improving ways to build relationships to ensure strong interprofessional collaboration.
Transcending Academic Power Structures: Navigating STEM Misinformation for Undergraduate Learning
(Ontario Library Association, 2022-02) Mutch, Stephanie; Mercer, Kathryn; Weaver, Kari D.
When students enter university, they learn that there are two types of information: information that can be found using library resources and the information that is found using Google. Sources are often framed in opposition to one another, with the library’s resources representing good and authoritative information, while other sources are considered risky and inferior. Librarians have started to question the usefulness of privileging certain types of information over others, acknowledging that highly useful and reliable information does exist outside of the confines of library resources. Specifically, by inherently devaluing sources found outside of the traditional academic context, how are we unintentionally perpetuating a power system that devalues non-academic voices, experiences, and contexts. Further, individuals with alternative viewpoints must first learn to act, think, and excel on academia’s terms before their worldviews and the information they have to share will be granted legitimacy by the academy. This poster uses critical theory to help position information as an element within the broader academic power structure. We are advocating for a more inclusive approach used in library instruction that encourages students to critically evaluate information on an individual basis.
Using a collaborative research approach to develop an interdisciplinary research agenda for the study of mobile health interventions for older adults.
(JMIR Mhealth Uhealth., 2015-02-10) Grindrod, Kelly; Baskerville, Neill; Giangregorio, Lora M.; Tomasson Goodwin, Jill; Sadat Rezai, Leila; Mercer, Kathryn; Burns, Catherine; Chang, Feng
Background: Seniors with chronic diseases are often called on to self-manage their conditions. Mobile health (mHealth) tools may be a useful strategy to help seniors access health information at the point of decision-making, receive real-time feedback and coaching, and monitor health conditions. However, developing successful mHealth interventions for seniors presents many challenges. One of the key challenges is to ensure the scope of possible research questions includes the diverse views of seniors, experts and the stakeholder groups who support seniors as they manage chronic disease. Objective: Our primary objective was to present a case-study of a collaborative research approach to the development of an interdisciplinary research agenda. Our secondary objectives were to report on the results of a nominal group technique (NGT) approach used generate research questions and to assess the success of including non-academic researchers to enrich the scope, priority, and total number of possible research questions. Methods: We invited researchers and stakeholders to participate in a full day meeting that included rapid-style presentations by researchers, health care professionals, technology experts, patients and community groups followed by group discussions. An NGT was used to establish group consensus on the following question: In your opinion, what research needs to be done to better understand the effectiveness, usability and design of mobile health apps and devices for older adults? Results: Overall, the collaborative approach was a very successful strategy to bring together a diverse group of participants with the same end goal. The 32 participants generated 119 items in total. The top three research questions that emerged from the NGT were related to adoption, the need for high quality tools and the digital divide. Strong sub-themes included privacy and security, engagement and design. The NGT also helped us include the perspectives information from non-academic researchers that would not have been captured if the process had been limited to the research team. Conclusions: Developing ways for patients and other stakeholders to have a voice when it comes to developing patient awareness as related to mHealth may guide future research into engagement, ownership, usability and design. It is our intention that our paper be used and adapted by other researchers to engage small or vulnerable populations often excluded from mHealth research and design.
