Development and Validation of the HL6: a Brief, Technology-Based Remote Measure of Health Literacy.

BACKGROUND: Most health literacy measures require in-person administration or rely upon self-report. OBJECTIVE: We sought to develop and test the feasibility of a brief, objective health literacy measure that could be deployed via text messaging or online survey. DESIGN: Participants were recruited from ongoing NIH studies to complete a phone interview and online survey to test candidate items. Psychometric analyses included parallel analysis for dimensionality and item response theory. After 9 months, participants were randomized to receive the final instrument via text messaging or online survey. PARTICIPANTS: Three hundred six English and Spanish-speaking adults with ≥ 1 chronic condition MAIN MEASURES: Thirty-three candidate items for the new measure and patient-reported physical function, anxiety, depression, and medication adherence. All participants previously completed the Newest Vital Sign (NVS) in parent NIH studies. KEY RESULTS: Participants were older (average 67 years), 69.6% were female, 44.3% were low income, and 22.0% had a high school level of education or less. Candidate items loaded onto a single factor (RMSEA: 0.04, CFI: 0.99, TLI: 0.98, all loadings >.59). Six items were chosen for the final measure, named the HL6. Items demonstrated acceptable internal consistency (α=0.73) and did not display differential item functioning by language. Higher HL6 scores were significantly associated with greater educational attainment (r=0.41), higher NVS scores (r=0.55), greater physical functioning (r=0.26), fewer depressive symptoms (r=-0.20), fewer anxiety symptoms (r=-0.15), and fewer barriers to medication adherence (r=-0.30; all p<.01). In feasibility testing, 75.2% of participants in the text messaging arm completed the HL6 versus 66.2% in the online survey arm (p=0.09). Socioeconomic disparities in completion were more common in the online survey arm. CONCLUSIONS: The HL6 demonstrates adequate reliability and validity in both English and Spanish. This performance-based assessment can be administered remotely using commonly available technologies with fewer logistical challenges than assessments requiring in-person administration.

Development and Validation of COVID-19 Vaccine Messaging Materials for Latinx Communities.

With pervasive health misinformation and mistrust, many of those at greatest risk from COVID-19 have demonstrated lower vaccine acceptance. In Chicago, IL, surveillance data has revealed lower rates of vaccine uptake among Black and Latinx individuals compared with others. We partnered with two local federally qualified health centers (FQHCs) to develop and implement language-concordant, low literacy patient education materials to promote COVID-19 vaccine knowledge, acceptance, and uptake. Our multi-phase study included: 1) iterative content generation and refinement by health literacy experts, health center providers and staff, and community-dwelling adults; and 2) materials testing via a two-arm randomized experiment among adults from Latinx communities in the Chicagoland area. Results indicate that our English and Spanish-language COVID-19 Fact Sheets increase knowledge about COVID-19 vaccination. These materials are publicly available and can be used by health centers or community organizations to promote COVID-19 vaccination among diverse populations.

Changes in COVID-19 Knowledge, Beliefs, Behaviors, and Preparedness Among High-Risk Adults from the Onset to the Acceleration Phase of the US Outbreak.

BACKGROUND: The US outbreak of coronavirus disease 2019 (COVID-19) accelerated rapidly over a short time to become a public health crisis. OBJECTIVE: To assess how high-risk adults' COVID-19 knowledge, beliefs, behaviors, and sense of preparedness changed from the onset of the US outbreak (March 13-20, 2020) to the acceleration phase (March 27-April 7, 2020). DESIGN: Longitudinal, two-wave telephone survey. PARTICIPANTS: 588 predominately older adults with ≥ 1 chronic condition recruited from 4 active, federally funded studies in Chicago. MAIN MEASURES: Self-reported knowledge of COVID-19 symptoms and prevention, related beliefs, behaviors, and sense of preparedness. KEY RESULTS: From the onset to the acceleration phase, participants increasingly perceived COVID-19 to be a serious public health threat, reported more changes to their daily routine and plans, and reported greater preparedness. The proportion of respondents who believed they were "not at all likely" to get the virus decreased slightly (24.9 to 22.4%; p = 0.04), but there was no significant change in the proportion of those who were unable to accurately identify ways to prevent infection (29.2 to 25.7%; p 0.14). In multivariable analyses, black adults and those with lower health literacy were more likely to report less perceived susceptibility to COVID-19 (black adults: relative risk (RR) 1.62, 95% confidence interval (CI) 1.07-2.44, p = 0.02; marginal health literacy: RR 1.96, 95% CI 1.26-3.07, p < 0.01). Individuals with low health literacy remained more likely to feel unprepared for the outbreak (RR 1.80, 95% CI 1.11-2.92, p = 0.02) and to express confidence in the federal government response (RR 2.11, 95% CI 1.49-3.00, p < 0.001) CONCLUSIONS: Adults at higher risk for COVID-19 continue to lack critical knowledge about prevention. While participants reported greater changes to daily routines and plans, disparities continued to exist in perceived susceptibility to COVID-19 and in preparedness. Public health messaging to date may not be effectively reaching vulnerable communities.

Investigating Health Literacy in Systemic Lupus Erythematosus: a Descriptive Review.

PURPOSE OF REVIEW: Inadequate health literacy is common among American adults, but little is known about the impact of health literacy in rheumatic diseases. The purpose of this article is to review studies investigating health literacy and its association with clinical outcomes in systemic lupus erythematosus (SLE). RECENT FINDINGS: Several validated health literacy measures have been examined in SLE patients. Low health literacy is associated with worse patient-reported outcomes and lower numeracy with higher disease activity. Two studies found no association of low health literacy with medication adherence. One randomized controlled trial tested a medication decision aid among patients with low health literacy. We found a paucity of studies exploring health literacy in SLE. Low health literacy is associated with worse patient-reported outcomes and limited numeracy with higher disease activity in SLE. Further studies are needed exploring the impact of low health literacy on clinical outcomes and the effectiveness of literacy-sensitive interventions.

Electronic Health Record-Based Strategy to Promote Medication Adherence Among Patients With Diabetes: Longitudinal Observational Study.

BACKGROUND: Poor medication adherence is common; however, few mechanisms exist in clinical practice to monitor how patients take medications in outpatient settings. OBJECTIVE: This study aimed to pilot test the Electronic Medication Complete Communication (EMC2) strategy, a low-cost, sustainable approach that uses functionalities within the electronic health record to promote outpatient medication adherence and safety. METHODS: The EMC2 strategy was implemented in 2 academic practices for 14 higher-risk diabetes medications. The strategy included: (1) clinical decision support alerts to prompt provider counseling on medication risks, (2) low-literacy medication summaries for patients, (3) a portal-based questionnaire to monitor outpatient medication use, and (4) clinical outreach for identified concerns. We recruited adult patients with diabetes who were prescribed a higher-risk diabetes medication. Participants completed baseline and 2-week interviews to assess receipt of, and satisfaction with, intervention components. RESULTS: A total of 100 patients were enrolled; 90 completed the 2-week interview. Patients were racially diverse, 30.0% (30/100) had a high school education or less, and 40.0% (40/100) had limited literacy skills. About a quarter (28/100) did not have a portal account; socioeconomic disparities were noted in account ownership by income and education. Among patients with a portal account, 58% (42/72) completed the questionnaire; 21 of the 42 patients reported concerns warranting clinical follow-up. Of these, 17 were contacted by the clinic or had their issue resolved within 24 hours. Most patients (33/38, 89%) who completed the portal questionnaire and follow-up interview reported high levels of satisfaction (score of 8 or greater on a scale of 1-10). CONCLUSIONS: Findings suggest that the EMC2 strategy can be reliably implemented and delivered to patients, with high levels of satisfaction. Disparities in portal use may restrict intervention reach. Although the EMC2 strategy can be implemented with minimal impact on clinic workflow, future trials are needed to evaluate its effectiveness to promote adherence and safety.

A Patient-Centered Prescription Drug Label to Promote Appropriate Medication Use and Adherence.

BACKGROUND: Patient misunderstanding of prescription drug label instructions is a common cause of unintentional misuse of medication and adverse health outcomes. Those with limited literacy and English proficiency are at greater risk. OBJECTIVE: To test the effectiveness of a patient-centered drug label strategy, including a Universal Medication Schedule (UMS), to improve proper regimen use and adherence compared to a current standard. DESIGN: Two-arm, multi-site patient-randomized pragmatic trial. PARTICIPANTS: English- and Spanish-speaking patients from eight community health centers in northern Virginia who received prescriptions from a central-fill pharmacy and who were 1) ≥30 years of age, 2) diagnosed with type 2 diabetes and/or hypertension, and 3) taking ≥2 oral medications. INTERVENTION: A patient-centered label (PCL) strategy that incorporated evidence-based practices for format and content, including prioritized information, larger font size, and increased white space. Most notably, instructions were conveyed with the UMS, which uses standard intervals for expressing when to take medicine (morning, noon, evening, bedtime). MAIN MEASURES: Demonstrated proper use of a multi-drug regimen; medication adherence measured by self-report and pill count at 3 and 9 months. KEY RESULTS: A total of 845 patients participated in the study (85.6 % cooperation rate). Patients receiving the PCL demonstrated slightly better proper use of their drug regimens at first exposure (76.9 % vs. 70.1 %, p = 0.06) and at 9 months (85.9 % vs. 77.4 %, p = 0.03). The effect of the PCL was significant for English-speaking patients (OR 2.21, 95 % CI 1.13-4.31) but not for Spanish speakers (OR 1.19, 95 % CI 0.63-2.24). Overall, the intervention did not improve medication adherence. However, significant benefits from the PCL were found among patients with limited literacy (OR 5.08, 95 % CI 1.15-22.37) and for those with medications to be taken ≥2 times a day (OR 2.77, 95 % CI 1.17-6.53). CONCLUSIONS: A simple modification to pharmacy-generated labeling, with minimal investment required, can offer modest improvements to regimen use and adherence, mostly among patients with limited literacy and more complex regimens. Trial Registration (ClinicalTrials.gov): NCT00973180, NCT01200849.

Different Measures, Different Outcomes? A Systematic Review of Performance-Based versus Self-Reported Measures of Health Literacy and Numeracy.

BACKGROUND: Health literacy (HL) and numeracy are measured by one of two methods: performance on objective tests or self-report of one's skills. Whether results from these methods differ in their relationship to health outcomes or use of health services is unknown. METHODS: We performed a systematic review to identify and evaluate articles that measured both performance-based and self-reported HL or numeracy and examined their relationship to health outcomes or health service use. To identify studies, we started with an AHRQ-funded systematic review of HL and health outcomes. We then looked for newer studies by searching MEDLINE from 1 February 2010 to 9 December 2014. We included English language studies meeting pre-specified criteria. Two reviewers independently assessed abstracts and studies for inclusion and graded study quality. One reviewer abstracted information from included studies while a second checked content for accuracy. RESULTS: We identified four "fair" quality studies that met inclusion criteria for our review. Two studies measuring HL found no differences between performance-based and self-reported HL for association with self-reported outcomes (including diabetes, stroke, hypertension) or a physician-completed rheumatoid arthritis disease activity score. However, HL measures were differentially related to a patient-completed health assessment questionnaire and to a patient's ability to interpret their prescription medication name and dose from a medication bottle. Only one study measured numeracy and found no difference between performance-based and self-reported measures of numeracy and colorectal cancer (CRC) screening utilization. However, in a moderator analysis from the same study, performance-based and self-reported numeracy were differentially related to CRC screening utilization when stratified by certain patient-provider communication behaviors (e.g., the chance to always ask questions and get the support that is needed). DISCUSSION: Most studies found no difference in the relationship between results of performance-based and self-reported measures and outcomes. However, we identified few studies using multiple instruments and/or objective outcomes.

Advancing Best Practices for Prescription Drug Labeling.

OBJECTIVE: Problematic prescription drug labeling has been cited as a root cause of patient misunderstanding, medication errors, and nonadherence. Although numerous studies have recently been conducted to identify and test labeling best practices, the last systematic review on this topic was conducted a decade ago. The objective of this review was, therefore, to examine, summarize, and update best practices for conveying written prescription medication information and instructions to patients. DATA SOURCES: English-language articles published from June 2005 to June 2015 were identified in MEDLINE and CINAHL by searching the following text words: 'medication OR prescription OR drug' AND 'label OR leaflet OR brochure OR pamphlet OR medication guide OR medication insert OR drug insert OR medication information OR drug information OR instructions' AND 'patient OR consumer.' Reference mining and secondary searches were also performed. STUDY SELECTION AND DATA EXTRACTION: A total of 31 articles providing evidence on how to improve written, prescription drug labeling for patient use were selected. Two reviewers independently screened articles, rated their quality, and abstracted data. DATA SYNTHESIS: Identified best practices included the use of plain language, improved formatting and organization, and more explicit instructions to improve patient comprehension. The use of icons had conflicting findings, and few studies tested whether practices improved knowledge or behaviors with patients' actual prescribed regimens. CONCLUSIONS: Future studies are needed to determine how specific modifications and improvements in drug labeling can enhance patient knowledge and behavior in actual use. Synthesizing best practices across all patient materials will create a more useful, coordinated system of prescription information.

Patient recall of health care provider counseling for opioid-acetaminophen prescriptions.

OBJECTIVE: The aim of this study was to determine the frequency and nature of physician, nurse, and pharmacist verbal counseling at the time of a new prescription for an opioid-acetaminophen containing medication as recalled by patients. DESIGN: A mixed methods approach with data from cross sectional, structured interviews was used. SETTING: The settings were one academic emergency department in Chicago, IL and one outpatient pharmacy at a public hospital in Atlanta, GA. PATIENTS: One hundred forty-nine patients receiving a new prescription for an opioid-acetaminophen medication were enrolled. METHODS: Interviews assessed patient recall of counseling they received from their physician, nurse, and pharmacist upon receiving the new prescription. Their responses were unitized and assigned to categories. RESULTS: One hundred forty-nine patients were enrolled; 61.1% African American and 58.4% female. Seven major categories of responses were noted; frequencies of patient recall for counseling in these categories were reported. Four categories related to the content of the counseling discussion were (1) details of administration (patient recall counseling from: physician/nurse only 44.3%, pharmacist only 5.4%, both providers 12.8%); (2) activities to avoid and side effects (36.2%, 4.7%, 8.7%); (3) medication indication (32.9%, 4%, 4%); and (4) addictive potential (9.3%, 1.3%, 0%). Three categories describe patients' recall of the interaction in broad terms: (5) being referred to print informational material accompanying the prescription (MD/RN only 7.4%, pharmacist only 20.1%, both providers 2.7%); (6) having questions solicited (0%, 11.4%, 0%); (7) having no interaction relating to medication counseling (3.4%, 32.2%, 1.3%). CONCLUSIONS: Patients infrequently recall counseling from providers on topics that are important to prevent harm from opioid-acetaminophen prescriptions. Future patient-centered clinical research should target identifying optimal strategies to convey these critical messages.

The association of health literacy with time in therapeutic range for patients on warfarin therapy.

Patients on warfarin therapy need to achieve and maintain anticoagulation control in order to experience the benefits of treatment while minimizing bleeding risk. Low health literacy skills may hinder patients' ability to use and adhere to warfarin in a safe and effective manner. The authors conducted this study to evaluate the relationship between health literacy and anticoagulation control among patients on chronic warfarin therapy. Participants were recruited from 2 diverse anticoagulation clinics in North Carolina. Time in therapeutic range (TTR) for warfarin therapy was used as a measure of anticoagulation control. Health literacy was assessed using the short form of the Test of Functional Health Literacy in Adults (S-TOFHLA). Of the 198 study participants, 51% had limited health literacy (S-TOFHLA score of 0-90) and 33% had poor anticoagulation control (TTR<50%). Participants with limited health literacy were less likely to correctly answer warfarin-related knowledge questions. Limited health literacy was significantly associated with TTR<50% (adjusted odds ratio=2.34, 95% CI [1.01, 5.46]). Findings indicate that limited health literacy is associated with poor anticoagulation control for patients on warfarin therapy. Lack of medication understanding may hinder the safe and effective use of this narrow therapeutic index drug.

Developing, optimizing, and evaluating patient infographics for diagnosing cardiac amyloidosis.

Objective: Advancements in diagnostics and treatment options for cardiac amyloidosis have improved patient outcomes, yet few patient education materials exist to help patients understand the disease and diagnosis process. We sought to develop and evaluate a set of plain language, patient-centered infographics describing the condition and common diagnostic tests. Methods: Using health literacy best practices, we developed 7 infographics which were further revised based on multilevel stakeholder feedback. To evaluate the materials, we recruited 100 patients from healthcare settings in Chicago, IL; participants completed a web-assisted interview during which they were randomized 1:1 to first view either our infographics or a standard material. Participants completed a knowledge assessment on their assigned material and subsequently reported impressions of both materials. Results: No differences were found between study arms in knowledge. The infographics took significantly less time to read and were more highly rated by participants in terms of appearance and understandability. Over two-thirds of participants preferred the infographics to the standard. Conclusions: The infographics created may improve the learning process about a complex condition and diagnosis process unknown to most adults. Innovation: These infographics are the first of their kind for cardiac amyloidosis and were created using health literacy best practices.

Impact of COVID-19 on the capacity to self-manage health and chronic conditions.

Objective: To investigate well-being, lifestyle behaviors, self-management capacity and healthcare utilization among adults with chronic conditions at the outbreak of the COVID-19 pandemic. Methods: Data was collected from two interviewer-administered telephone surveys conducted between March 27 - May 22, 2020. Participants were patients at Chicago-area clinics. Self-report and validated measures were used for study-related outcomes. Results: A total of 553 participants (age range 23-88) completed data collection at both timepoints. One in five (20.7%) participants experienced stress due to the coronavirus most or all the time and rates of negative well-being were high (WHO-5 Index mean = 58.7%). Almost a quarter (22.3%) engaged in hazardous drinking and 79.7% reported insufficient physical activity. Nearly one in four participants (23.7%) avoided seeking medical care due to worry about COVID-19. In multivariable analyses, greater COVID-19 related stress was associated with less physical activity, lower self-efficacy, greater difficulty managing health and medications, and delays in seeking medical care due to the coronavirus. Conclusions: Mental well-being, lifestyle behaviors, self-management capacity, and healthcare utilization were impacted in the months following the COVID outbreak. Innovation: These findings suggest health systems should implement proactive measures for detecting and treating emotional and behavioral COVID-related concerns.

Evaluation of language concordant, patient-centered drug label instructions.

BACKGROUND: Despite federal laws requiring language access in healthcare settings, most US pharmacies are unable to provide prescription (Rx) medication instructions to limited English proficient (LEP) patients in their native language. OBJECTIVE: To evaluate the efficacy of health literacy-informed, multilingual Rx instructions (the ConcordantRx instructions) to improve Rx understanding, regimen dosing and regimen consolidation in comparison to standard, language-concordant Rx instructions. DESIGN: Randomized, experimental evaluation. PARTICIPANTS: Two hundred and two LEP adults speaking five non-English languages (Chinese, Korean, Russian, Spanish, Vietnamese), recruited from nine clinics and community organizations in San Francisco and Chicago. INTERVENTION: Subjects were randomized to review Rx bottles with either ConcordantRx or standard instructions. MAIN MEASURES: Proper demonstration of common prescription label instructions for single and multi-drug medication regimens. Regimen consolidation was assessed by determining how many times per day subjects would take medicine for a multi-drug regimen. KEY RESULTS: Subjects receiving the ConcordantRx instructions demonstrated significantly greater Rx understanding, regimen dosing and regimen consolidation in comparison to those receiving standard instructions (incidence rate ratio [IRR]: 1.25, 95 % confidence interval [CI]: 1.06-1.48; P= 0.007 for Rx understanding, IRR: 1.19, 95 % CI: 1.03-1.39; P= 0.02 for regimen dosing and IRR: 0.76, 95 % CI: 0.64-0.90; P= 0.001 for regimen consolidation). In most cases, instruction type was the sole, independent predictor of outcomes in multivariate models controlling for relevant covariates. CONCLUSIONS: There is a need for standardized, multilingual Rx instructions that can be implemented in pharmacy practices to promote safe medication use among LEP patients. The ConcordantRx instructions represent an important step towards achieving this goal.

Usability of FDA-approved medication guides.

BACKGROUND: Medication guides are required documents to be distributed to patients in order to convey serious risks associated with certain prescribed medicines. Little is known about the effectiveness of this information to adequately inform patients on safe use. OBJECTIVE: To examine the readability, suitability, and comprehensibility of medication guides, particularly for those with limited literacy. DESIGN: Assessments of suitability and readability of 185 medication guides, and a sub-study examining change in suitability and readability from 2006 to 2010 among 32 of the medication guides (Study 1); 'open book' comprehension assessment of medication guides (Study 2). SETTING: Two general internal medicine clinics in Chicago, IL. PATIENTS: Four hundred and forty-nine adults seeking primary care services, ages 18-85. MEASUREMENTS: For Study 1, the Suitability Assessment of Materials (SAM) and Lexile score for readability. For Study 2, a tailored comprehension assessment of content found in three representative medication guides. RESULTS: The 185 analyzed medication guides were on average 1923 words (SD = 1022), with a mean reading level of 10-11th grade. Only one medication guide was deemed suitable in SAM analyses. None provided summaries or reviews, or framed the context first, while very few were rated as having made the purpose evident (8 %), or limited the scope of content (22 %). For Study 2, participants' comprehension of medication guides was poor (M = 52.7 % correct responses, SD = 22.6). In multivariable analysis, low and marginal literacy were independently associated with poorer understanding (ß = -14.3, 95 % CI -18.0 - -10.6, p < 0.001; low: ß = -23.7, 95 % CI -28.3 - -19.0, p < 0.001). CONCLUSION: Current medication guides are of little value to patients, as they are too complex and difficult to understand especially for individuals with limited literacy. Explicit guidance is offered for improving these print materials.

Risk of unintentional overdose with non-prescription acetaminophen products.

BACKGROUND: There is increasing concern over the risk of consumer unintentional misuse of non-prescription (a.k.a. 'over-the-counter') medications containing acetaminophen, which could lead to acute liver failure. OBJECTIVE: To determine the prevalence of potential misuse and overdose of over-the-counter medications containing acetaminophen, either alone or in combination. DESIGN: Cross-sectional, structured interviews with literacy assessment. SETTING: One academic and one community-based general internal medicine practice in Chicago, IL, and one academic general internal medicine practice and a public hospital clinic in Atlanta, GA. PATIENTS: Five hundred adults seeking primary care, ages 18-80. MEASUREMENT: Demonstration of how and when patients would take over-the-counter medications containing acetaminophen, alone or in combination with one another, over a 24-hour period. RESULTS: Overall, 23.8 % of participants demonstrated they would overdose on a single over-the-counter acetaminophen product by exceeding a dose of four grams in a 24-hour period; 5.2 % made serious errors by dosing out more than six grams. In addition, 45.6 % of adults demonstrated they would overdose by 'double-dipping' with two acetaminophen-containing products. In multivariable analyses, limited literacy (Relative Risk Ratio (RR) 1.65, 95 % Confidence Interval (CI) 1.03-2.66) and heavy acetaminophen use in the past six months (RR 1.70, 95 % CI 1.10-2.64) were independently associated with overdosing over-the-counter products. CONCLUSION: Misunderstanding of the active ingredient and proper instructions for over-the-counter medications containing acetaminophen is common. The potential for errors and adverse events associated with unintentional misuse of these products is substantial, particularly among heavy users of acetaminophen and those with limited literacy.

Literacy barriers to colorectal cancer screening in community clinics.

This article examines the relationship between literacy and colorectal cancer (CRC) screening knowledge, beliefs, and experiences, with a focus on fecal occult blood tests (FOBTs). Participants were 975 patients in 8 Louisiana federally qualified health centers. Participants were 50 years of age or older and not up to date with CRC screening; approximately half (52%) had low literacy (less than a 9th-grade level). Participants with low literacy were less likely than were those with adequate literacy to be aware of advertisements promoting CRC screening (58.7% vs. 76.3%, p < .0001) or to believe it was very helpful to find CRC early (74.5% vs. 91.9%, p < .0001). The majority of participants had positive beliefs about the benefits of CRC screening using FOBTs. Participants with low literacy had more perceived barriers to FOBT completion and were more likely to strongly agree or agree that FOBTs would be confusing, embarrassing, or a lot of trouble; however, none of these remained significant in multivariate analyses controlling for relevant covariates. Confidence in being able to obtain an FOBT kit was high among those with low and adequate literacy (89.8% vs. 93.1%, respectively, p = .20); yet multivariate analyses revealed a significant difference in regard to literacy (p = .04) with low-literacy participants indicating less confidence. There was no significant difference by literacy in ever receiving a physician recommendation for CRC screening (38.4% low vs. 39.0% adequate, p = .79); however, multivariate analyses revealed significant differences in FOBT completion by literacy (p = .036). Overall, findings suggest that literacy is a factor in patients' CRC knowledge, beliefs, and confidence in obtaining a FOBT.

Navigating medication-taking after kidney transplant.

BACKGROUND: Mixed methods are valuable in understanding multifaceted health behaviors like medication adherence. Kidney transplant recipients (KTRs) have complex medication regimens and are more vulnerable to nonadherence relative to other transplant recipients. Yet mixed methods have not been widely applied to examine adherence among KTRs, especially in relation to prescribed medications beyond immunosuppressants. OBJECTIVES: As part of a sequential approach, we used in-depth interviews to better understand findings from a previous quantitative study and to describe additional factors that influence prescription medication-taking among adult KTRs. METHODS: Semi-structured interviews were conducted with a purposive sample of 14 adult KTRs recruited from a transplant center in Chicago, IL. Deductive and inductive content analysis was used to code transcripts and identify key themes. RESULTS: Across the sample, we identified insurance challenges, disruptions in routine, and poor mental well-being as barriers to adherence at the patient level. For Black and Hispanic KTRs, poor communication between providers and disjointed care transitions posed additional barriers at the health system level. Compared with White KTRs, Black and Hispanic KTRs experienced greater medication burden due to comorbidities, while medication and digital literacy challenges were unique to Hispanic KTRs. CONCLUSION: KTRs are often motivated to take medications as prescribed, but sometimes lack the capacity or support to do so. Eliciting KTR perspectives is necessary in addressing knowledge and resource gaps at the patient and health system levels to improve adherence. In addition, recognizing the relative burden of taking comorbidity medications compared with immunosuppressants may important, particularly for Black and Hispanic KTRs.

Trajectories of perceived susceptibility to COVID-19 over a year: The COVID-19 & chronic conditions (C3) cohort study.

ABSTRACT: The U.S. public health response to coronavirus disease 2019 (COVID-19) has been widely criticized as having downplayed the potential implications COVID-19 could have on one's personal health. Despite the unprecedented threat of COVID-19, many individuals still believed that it was not at all likely that they would become infected. We sought to investigate trends in adults' perceived susceptibility to COVID-19 over the first year of the pandemic, whether distinct trajectories emerged, and if these trajectories differed by participant socio-demographic characteristics.This was a longitudinal cohort study with 5 time points of data collection (March 13, 2020-March 3, 2021). Subjects included 627 adults living with ≥1 chronic conditions, who completed a baseline interview and at least one follow-up interview. In addition to collecting relevant socio-demographic characteristics, participants' perceived susceptibility to COVID-19 across time was assessed and classified into distinct trajectories.Nearly two-thirds (62.2%) of participants perceived themselves to be highly susceptible to COVID-19 from the onset of the pandemic ("early responders") and sustained this over a year, a third (29.0%) eventually perceived themselves to be highly susceptible ("late responders"), and 8.8% maintained a low likelihood of susceptibility throughout the pandemic ("non-responders"). In multivariable analyses, compared to White participants, Latinx participants were significantly more likely to be non-responders and report low likelihood of perceived susceptibility (Risk Ratio [RR]: 3.46; 95% confidence interval: 1.19, 10.1), as were Black participants (RR: 5.49; 95% confidence interval: 2.19, 13.8).A year into the COVID-19 pandemic, 1 out of 11 participants persistently did not think they might be susceptible and potentially infected. Future studies are needed to understand reasons why certain individuals, particularly those of racial/ethnic minorities, did not perceive themselves at risk for infection.

Effect of standardized, patient-centered label instructions to improve comprehension of prescription drug use.

OBJECTIVE: To evaluate the effectiveness of standardized, patient-centered label (PCL) instructions to improve comprehension of prescription drug use compared with typical instructions. METHODS: A total of 500 adult patients recruited from 2 academic and 2 community primary care clinics in Chicago, IL and Shreveport, LA were assigned to receive as follows: (1) standard prescription instructions written as times per day (once, twice 3 times per day) (usual care), (2) PCL instructions that specify explicit timing with standard intervals (morning, noon, evening, bedtime) (PCL), or (3) PCL instructions with a graphic aid to visually depict dose and timing of the medication (PCL + Graphic). The outcome was correct interpretation of label instructions. RESULTS: Instructions with the PCL format were more likely to be correctly interpreted compared with standard instructions (adjusted relative risk [RR]: 1.33, 95% confidence interval [CI]: 1.25-1.41). Inclusion of the graphic aid (PCL + Graphic) decreased rates of correct interpretation compared with PCL instructions alone (RR: 0.93; 95% CI: 0.89-0.97). Patients with low literacy were better able to interpret PCL instructions (low literacy: RR: 1.39; 95% CI: 1.14-1.68; P = 0.001). CONCLUSION: The PCL approach could improve patients' understanding and use of their medication regimen.

Improving pregnancy drug warnings to promote patient comprehension.

OBJECTIVE: We sought to evaluate the effectiveness of a pharmaceutical labeling strategy intended to improve comprehension of a teratogen warning. STUDY DESIGN: This is a secondary analysis that evaluated women of childbearing age who were assigned prescription containers with the current teratogen warning, a label with simplified text, or a label with simplified text and icons. The association between label type and understanding of label instructions was assessed. RESULTS: A total of 132 women were interviewed. Comprehension of the icon label (94%) was higher than for the standard and enhanced text-only labels (76% and 79%), respectively (P < .05). Adjustment for age, race/ethnicity, education, literacy, and number of current medications revealed that the label with the enhanced text and icon yielded superior comprehension (risk ratio vs standard, 1.26; 95% confidence interval, 1.04-1.53; risk ratio vs enhanced, 1.22; 95% confidence interval, 1.02-1.46). CONCLUSION: In our study, a teratogen warning label that had easy-to-read messages with icons significantly improved comprehension.
