Empowering Health Care Workers on Social Media to Bolster Trust in Science and Vaccination During the Pandemic: Making IMPACT Using a Place-Based Approach.

BACKGROUND: Given the widespread and concerted efforts to propagate health misinformation on social media, particularly centered around vaccination during the pandemic, many groups of clinicians and scientists were organized on social media to tackle misinformation and promote vaccination, using a national or international lens. Although documenting the impact of such social media efforts, particularly at the community level, can be challenging, a more hyperlocal or "place-based approach" for social media campaigns could be effective in tackling misinformation and improving public health outcomes at a community level. OBJECTIVE: We aimed to describe and document the effectiveness of a place-based strategy for a coordinated group of Chicago health care workers on social media to tackle misinformation and improve vaccination rates in the communities they serve. METHODS: The Illinois Medical Professionals Action Collaborative Team (IMPACT) was founded in March 2020 in response to the COVID-19 pandemic, with representatives from major academic teaching hospitals in Chicago (eg, University of Chicago, Northwestern University, University of Illinois, and Rush University) and community-based organizations. Through crowdsourcing on multiple social media platforms (eg, Facebook, Twitter, and Instagram) with a place-based approach, IMPACT engaged grassroots networks of thousands of Illinois health care workers and the public to identify gaps, needs, and viewpoints to improve local health care delivery during the pandemic. RESULTS: To address vaccine misinformation, IMPACT created 8 "myth debunking" infographics and a "vaccine information series" of 14 infographics that have generated >340,000 impressions and informed the development of vaccine education for the Chicago Public Libraries. IMPACT delivered 13 policy letters focusing on different topics, such as health care worker personal protective equipment, universal masking, and vaccination, with >4000 health care workers signatures collected through social media and delivered to policy makers; it published over 50 op-eds on COVID-19 topics in high-impact news outlets and contributed to >200 local and national news features. Using the crowdsourcing approach on IMPACT social media channels, IMPACT mobilized health care and lay volunteers to staff >400 vaccine events for >120,000 individuals, many in Chicago's hardest-hit neighborhoods. The group's recommendations have influenced public health awareness campaigns and initiatives, as well as research, advocacy, and policy recommendations, and they have been recognized with local and national awards. CONCLUSIONS: A coordinated group of health care workers on social media, using a hyperlocal place-based approach, can not only work together to address misinformation but also collaborate to boost vaccination rates in their surrounding communities.

A coordinated strategy to develop and distribute infographics addressing COVID-19 vaccine hesitancy and misinformation.

BACKGROUND: Visual communication strategies are becoming increasingly prevalent for conveying information to health professionals as well as to the general public. The potential of social media for rapid knowledge dissemination using infographics was recognized early in the coronavirus disease (COVID-19) pandemic by health professionals. OBJECTIVE: The purpose of this study was to describe a coalition of health professionals' approach to developing infographics about COVID-19 vaccines and the reach and engagement of those infographics when shared through social media. METHODS: Infographics were created by a core team within the coalition following a stepwise approach. Each underwent a multistep review process, readability evaluation, and translation into Spanish. Infographics were then shared through multiple social media platforms. They were grouped into 1 of 3 categories for this analysis: COVID-19 vaccine series, myth debunkers, or other. RESULTS: All infographics had greater outreach, impressions, and engagement on Twitter than they did on other platforms. When comparing the 3 groups, no 1 infographic type was consistently performing higher than the others. CONCLUSION: Each infographic reached thousands to tens of thousands of people. We do not know whether those who viewed these infographics changed their perspective on vaccination, so we are unable to draw a conclusion about their impact on vaccine hesitancy based on this study alone.

Understanding barriers to lung cancer screening in primary care.

BACKGROUND: Low-dose computed tomography (LDCT) scan for lung cancer screening is underutilized. Studies suggest that up to one-third of providers do not know the current lung cancer screening guidelines. Thus, identifying the barriers to utilization of LDCT scan is essential. METHODS: Primary care providers in three different healthcare settings in the United States were surveyed to assess provider knowledge of LDCT scan screening criteria, lung cancer screening practices, and barriers to the utilization of LDCT scan screening. Fisher's Exact, Chi-Squared, and Kruskal-Wallis tests were used to compare provider responses. Multivariable logistic regression was used to test the association between provider characteristics and the likelihood of utilizing LDCT scan for lung cancer screening. RESULTS: The survey was sent to 614 providers, with a 15.7% response rate. Overall, 29.2% of providers report never ordering LDCT scans for eligible patients. Providers practicing at a community or academic hospital more frequently order LDCT scans than those practicing at a safety net hospital. Academic- and community-based providers received a significantly higher mean knowledge score than safety net-based providers [academic 6.84 (SD 1.33), community 6.72 (SD 1.46), safety net 5.85 (SD 1.38); P<0.01]. Overall, only 6.2% of respondents correctly identified all six Centers for Medicare and Medicaid Services eligibility criteria when challenged with three incorrect criteria. Common barriers to utilization of LDCT scan included failure of the electronic medical record (EMR) to notify providers of eligible patients (54.7%), patient refusal (37%), perceived high false-positive rate leading to unnecessary procedures (18.9%), provider time constraints (16.8%), and lack of insurance coverage (13.7%). CONCLUSIONS: Provider knowledge of lung cancer screening guidelines varies, perhaps contributing to underutilization of LDCT scan for lung cancer screening. Improved provider education at safety net hospitals and improving EMR-based best practice alerts may improve the rate of lung cancer screening.

Patient Perceptions About Prediabetes and Preferences for Diabetes Prevention.

PURPOSE: The purpose of this study was to explore how adults with prediabetes perceive their risk of developing diabetes and examine their preferences for evidence-based treatment options to prevent diabetes. METHODS: A qualitative study was conducted in 2 large Midwest primary care practices, involving in-depth semistructured interviews with 35 adult patients with prediabetes. RESULTS: This ethnically diverse (77% nonwhite) sample of middle-aged primary care patients exhibited multiple diabetes risk factors. Knowledge gaps about prediabetes and its medical management were pervasive. Most patients overestimated the risk of developing diabetes and were not familiar with evidence-based treatment options for prediabetes. They suggested that receiving brief, yet specific information about these topics during the study interview motivated them to act. The majority of participants considered both intensive lifestyle intervention and metformin acceptable treatment options. Many preferred initial treatment with intensive lifestyle intervention but would take metformin if their efforts at lifestyle change failed and their primary care physician recommended it. Some participants expressed wanting to combine both treatments. CONCLUSIONS: This qualitative study highlights potential opportunities to promote patient-centered dialogue about prediabetes in primary care settings. Providing patients specific information about the risk of developing diabetes and evidence-based treatment options to prevent or delay its onset may encourage action. Physicians' prediabetes counseling efforts should be informed by the finding that most patients consider both intensive lifestyle intervention and metformin acceptable treatment options.

Electronic health record identification of prediabetes and an assessment of unmet counselling needs.

RATIONALE, AIMS AND OBJECTIVES: Large clinical trials demonstrate that lifestyle modification can prevent or delay the onset of diabetes in those with prediabetes. However, recent National Health and Nutrition Survey data suggest that prediabetes often goes unrecognized, and the majority of prediabetic individuals do not report having received lifestyle advice from physicians. We explored whether electronic health record (EHR) query of glucose measurements can identify prediabetic patients, and we estimated rates of prediabetic lifestyle counselling in a large, urban, primary care practice. METHODS: Electronic search identified patients with plasma glucose levels of 100 to 199 mg dL(-1) between 1 June 2007 and 1 June 2009, excluding those with diabetes or diabetic medications/supplies. From these 5366 patients, 100 randomly selected patients underwent classification into provisional categories based on available EHR data: likely prediabetes, likely diabetes, glucose abnormality in the setting of acute illness, or normal glucose metabolism. In those likely to have prediabetes, we assessed lifestyle modification counselling. RESULTS: Fifty-eight per cent (95% CI 48% to 68%) of patients sampled were likely to have prediabetes. Fourteen per cent of those sampled were likely to have diabetes. Thirty-one per cent of prediabetics (95% CI 22% to 42%) had documented lifestyle counselling. Counselled patients had a significantly higher baseline mean body mass index compared to those not counselled (34.1 versus 29.9, P = 0.037). CONCLUSIONS: EHR query using glucose measurements can identify prediabetic patients and those requiring further glucose metabolism evaluation, including those with undiagnosed diabetes. Future research should investigate EHR-based, population-level interventions to facilitate prediabetes recognition and counselling.

Poorer clock draw test scores are associated with greater functional impairment in peripheral artery disease: the Walking and Leg Circulation Study II.

We hypothesized that, in the absence of clinically recognized dementia, cognitive dysfunction measured by the clock draw test (CDT) is associated with greater functional impairment in men and women with peripheral artery disease (PAD). Participants were men and women aged 60 years and older with Mini-Mental Status Examination scores ≥ 24 with PAD (n = 335) and without PAD (n = 234). We evaluated the 6-minute walk test, 4-meter walking velocity at usual and fastest pace, the Short Physical Performance Battery (SPPB), and accelerometer-measured physical activity. CDTs were scored using the Shulman system as follows: Category 1 (worst): CDT score 0-2; Category 2: CDT score 3; Category 3 (best): CDT score 4-5. Results were adjusted for age, sex, race, education, ankle-brachial index (ABI), and comorbidities. In individuals with PAD, lower CDT scores were associated with slower 4-meter usual-paced walking velocity (Category 1: 0.78 meters/second; Category 2: 0.83 meters/second; Category 3: 0.86 meters/second; p-trend = 0.025) and lower physical activity (Category 1: 420 activity units; Category 2: 677 activity units; Category 3: 701 activity units; p-trend = 0.045). Poorer CDT scores were also associated with worse functional performance in individuals without PAD (usual and fast-paced walking velocity and SPPB, p-trend = 0.022, 0.043, and 0.031, respectively). In conclusion, cognitive impairment identified with CDT is independently associated with greater functional impairment in older, dementia-free individuals with and without PAD. Longitudinal studies are necessary to explore whether baseline CDT scores and changes in CDT scores over time can predict long-term decline in functional performance in individuals with and without PAD.
