Optimizing Telehealth Services: A Mixed-Methods Needs Assessment Conducted Among Community Health Center Patients.

BACKGROUND: The COVID-19 pandemic increased telehealth services in federally funded community health centers (CHCs). Yet little is known about common determinants of use among CHC patients. OBJECTIVE: We examined the use of telehealth among patient participants at 1 large CHC network providing care to underserved populations at urban and suburban sites in the Midwest. METHODS: We conducted a mixed-methods study utilizing a sequential explanatory design. Participants were English and/or Spanish-speaking adults who attended ≥1 visits for themselves or their child over a 12-month period at any practice location. Research staff conducted a structured phone survey of eligible adults. The results subsequently facilitated purposive sampling of telehealth "users" and "nonusers" for qualitative phone interviews. RESULTS: The survey participants included 500 adults. Most had access to the resources needed to utilize telehealth, including a smartphone (90.4%) and home internet (83.0%). About half (50.8%) "rarely or never" had problems with internet speed, reliability, or quality. Most (81.1%) were aware of the patient portal and 59.8% had utilized video visits. Participants who were Spanish-speaking and with limited English proficiency faced some of the greatest barriers. Qualitative interview participants included 12 users and 12 nonusers of telehealth. Users found telehealth convenient and efficient, while nonusers lacked awareness about how telehealth services could be beneficial or needed assistance to sign up, join, or use telehealth. CONCLUSIONS: Most participants had the resources and awareness necessary to use telehealth services. Those who use them appreciate the convenience and efficiency. Nevertheless, additional support may be needed to prevent telehealth from exacerbating health inequities.

Early COVID-19 Attitudes and Behaviors and Their Associations With Later Infection: A Local Perspective From One U.S. City.

BACKGROUND: At the onset of the pandemic, there was poor public awareness and inaction in response to COVID-19; it is less known whether this translated to subsequent infections. OBJECTIVES: To explore whether adults who perceived COVID-19 as less of a threat and who were not taking early actions were more likely to become infected over the following year. RESEARCH DESIGN: Survey data from the ongoing (COVID-19 & Chronic Conditions (C3) anonymized for review) cohort study. PARTICIPANTS: Six hundred forty-two adults with a mean age of 63 and ≥1 chronic condition. MEASURES: Self-reported attitudes and behaviors regarding COVID-19 were assessed from March 13 to April 3, 2020, and COVID-19 infection status was captured between May 2020 and January 2021. Bivariate and multivariable analyses examined associations between early perceptions and behaviors with later infection. RESULTS: Approximately 7% reported infection with COVID-19 (N = 46). Adults who perceived the threat of COVID-19 less seriously at the initial outbreak were more likely to test positive over the following year [odds ratio (OR): 0.81, CI: 0.70-0.94; P = 0.006]. Those who were less likely to believe their actions would affect whether they would become infected were more likely to test positive (OR: 0.87, CI: 0.77-0.99; P = 0.03), as were adults who reported not changing their routines (OR: 0.45; CI: 0.24-0.85; P = 0.01). CONCLUSIONS: Adults with delayed responses in acknowledging the threat of COVID-19 and in changing behaviors were more likely to contract the virus. This investigation provides insight into the consequences of inadequate public understanding and response to COVID-19, and it highlights the importance of promoting early awareness among high-risk groups during public health crises.

Screening for Prediabetes and Diabetes in a National Network of Federally Qualified Health Centers: An Observational Study.

BACKGROUND: In 2021, the U.S. Preventive Services Task Force (USPSTF) recommended screening for prediabetes and diabetes among adults aged 35-70 years with overweight or obesity. Studying dysglycemia screening in federally qualified health centers (FQHCs) that serve vulnerable patient populations is needed to understand health equity implications of this recommendation. OBJECTIVE: To investigate screening practices among FQHC patients who would be eligible according to the 2021 USPSTF recommendation. DESIGN: Retrospective cohort study analyzing electronic health records from a national network of 282 FQHC sites. PARTICIPANTS: We included 183,329 patients without prior evidence of prediabetes or diabetes, who had ≥ 1 office visit from 2018-2020. MAIN MEASURES: Screening eligibility was based on age and measured body mass index (BMI). The primary outcome, screening completion, was ascertained using hemoglobin A1c or fasting plasma glucose results from 2018-2020. KEY RESULTS: Among 89,543 patients who would be eligible according to the 2021 USPSTF recommendation, 53,263 (59.5%) were screened. Those who completed screening had higher BMI values than patients who did not (33.0 ± 6.7 kg/m2 vs. 31.9 ± 6.2 kg/m2, p < 0.001). Adults aged 50-64 years had greater odds of screening completion relative to younger patients (OR 1.13, 95% CI: 1.10-1.17). Patients from racial and ethnic minority groups, as well as those without health insurance, were more likely to complete screening than White patients and insured patients, respectively. Clinical risk factors for diabetes were also associated with dysglycemia screening. Among patients who completed screening, 23,588 (44.3%) had values consistent with prediabetes or diabetes. CONCLUSIONS: Over half of FQHC patients who would be eligible according to the 2021 USPSTF recommendation were screened. Screening completion was higher among middle-aged patients, those with greater BMI values, as well as vulnerable groups with a high risk of developing diabetes. Future research should examine adoption of the 2021 USPSTF screening recommendation and its impact on health equity.

Association between medication regimen complexity and glycemic control among patients with type 2 diabetes.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) and comorbid conditions require patients to take complex medication regimens. Greater regimen complexity has been associated with poorer T2DM management; however, the relationship between overall regimen complexity and glycemic control is unclear. OBJECTIVES: Our objectives were: (1) to examine associations between regimen complexity (with the Medication Regimen Complexity Index [MRCI]) and glycemic control (A1C), and (2) to compare overall MRCI with other measures of regimen complexity (overall and diabetes-specific medication count) and diabetes-specific MRCI. METHODS: This was a secondary data analysis of cross-sectional data from a parent trial. Participants were patients with T2DM taking at least 3 chronic medications followed in safety net clinics in the Chicago area. The MRCI measures complexity based on dosing frequency, route of administration, and special instructions for prescribed medications. MRCI scores were created for overall regimens and diabetes-specific medications. Sociodemographics and outpatient visit utilization were included in models as covariates. Linear regression was used to examine the associations between variables of interest and hemoglobin A1C. RESULTS: Participants (N = 432) had a mean age of 56.9 years, most were female (66.0%), and Hispanic or Latino (73.3%). Regimen complexity was high based on overall medications (mean = 6.6 medications, SD: 3.09) and MRCI (mean = 21.4, SD: 11.3). Higher diabetes-specific MRCI was associated with higher A1C in bivariate and multivariable models. In multivariable models, overall MRCI greater than 14, fewer outpatient health care visits, male gender, and absence of health insurance were independently associated with higher A1C. The variance in A1C explained by MRCI was higher compared to medication count for overall and diabetes-specific regimen complexity. CONCLUSIONS: More complex regimens are associated with worse A1C and measuring complexity with MRCI may have advantages. Deprescribing, increasing insurance coverage, and promoting engagement in health care may improve A1C among underserved populations with complex regimens.

Low health numeracy is associated with higher disease activity in systemic lupus erythematosus.

OBJECTIVE: Evidence suggests low health literacy is prevalent in the United States and associated with worse clinical outcomes, yet few studies have investigated health literacy in systemic lupus erythematosus (SLE). The objective of this study was to determine the prevalence of low health literacy and numeracy in lupus patients and to examine its association with disease characteristics. METHODS: Patients with SLE were recruited from an academic center clinic. Participants completed in-person assessments of health literacy (Rapid Estimate of Adult Literacy in Medicine, REALM) and numeracy (Numeracy Understanding in Medicine Instrument Shortened Version, S-NUMi). Clinical disease activity measures were obtained, including urine protein to creatinine ratio (UPC), Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and physician global assessment (PhGA) scores. RESULTS: Ninety-five SLE patients participated in the study; 13% had low health literacy and 73% had limited health numeracy. Patients with lower health literacy and numeracy were more likely to be Black, have Medicaid insurance, and earn income <$50 K annually. In linear regression models, patients with limited health numeracy had, on average, PhGA scores 0.31 points higher (95% CI: 0.02, 0.60) than patients with adequate numeracy, after adjusting for race and age. No clinical outcomes were associated with health literacy. CONCLUSION: In this exploratory study, we found SLE patients with low numeracy had higher disease activity. Our findings indicate that lower health literacy and numeracy are more common among Black and socioeconomically disadvantaged patients. Additional research will be needed to investigate the impact of health literacy on other outcomes and racial disparities in SLE.

Awareness, Attitudes, and Actions Related to COVID-19 Among Adults With Chronic Conditions at the Onset of the U.S. Outbreak: A Cross-sectional Survey.

BACKGROUND: The evolving outbreak of coronavirus disease 2019 (COVID-19) is requiring social distancing and other measures to protect public health. However, messaging has been inconsistent and unclear. OBJECTIVE: To determine COVID-19 awareness, knowledge, attitudes, and related behaviors among U.S. adults who are more vulnerable to complications of infection because of age and comorbid conditions. DESIGN: Cross-sectional survey linked to 3 active clinical trials and 1 cohort study. SETTING: 5 academic internal medicine practices and 2 federally qualified health centers. PATIENTS: 630 adults aged 23 to 88 years living with 1 or more chronic conditions. MEASUREMENTS: Self-reported knowledge, attitudes, and behaviors related to COVID-19. RESULTS: A fourth (24.6%) of participants were "very worried" about getting the coronavirus. Nearly a third could not correctly identify symptoms (28.3%) or ways to prevent infection (30.2%). One in 4 adults (24.6%) believed that they were "not at all likely" to get the virus, and 21.9% reported that COVID-19 had little or no effect on their daily routine. One in 10 respondents was very confident that the federal government could prevent a nationwide outbreak. In multivariable analyses, participants who were black, were living below the poverty level, and had low health literacy were more likely to be less worried about COVID-19, to not believe that they would become infected, and to feel less prepared for an outbreak. Those with low health literacy had greater confidence in the federal government response. LIMITATION: Cross-sectional study of adults with underlying health conditions in 1 city during the initial week of the COVID-19 U.S. outbreak. CONCLUSION: Many adults with comorbid conditions lacked critical knowledge about COVID-19 and, despite concern, were not changing routines or plans. Noted disparities suggest that greater public health efforts may be needed to mobilize the most vulnerable communities. PRIMARY FUNDING SOURCE: National Institutes of Health.

Knowledge and Behaviors of Adults with Underlying Health Conditions During the Onset of the COVID-19 U.S. Outbreak: The Chicago COVID-19 Comorbidities Survey.

Accurate understanding of COVID-19 safety recommendations early in the outbreak was complicated by inconsistencies in public health and media messages. We sought to characterize high-risk adults' knowledge of COVID-19 symptoms, prevention strategies, and prevention behaviors. We used data from the Chicago COVID-19 Comorbidities (C3) survey collected between March 13 thru March 20, 2020. A total of 673 predominately older adults with ≥ 1 chronic condition completed the telephone interview. Knowledge was assessed by asking participants to name three symptoms of COVID-19 and three actions to prevent infection. Participants were then asked if and how they had changed plans due to coronavirus. Most participants could identify three symptoms (71.0%) and three preventive actions (69.2%). Commonly reported symptoms included: fever (78.5%), cough (70.6%), and shortness of breath (45.2%); preventive actions included: washing hands (86.5%) and social distancing (86.2%). More than a third of participants reported social distancing themselves (38.3%), and 28.8% reported obtaining prescription medication to prepare for the outbreak. In multivariable analyses, no participant characteristics were associated with COVID-19 knowledge. Women were more likely than men, and Black adults were less likely than White adults to report practicing social distancing. Individuals with low health literacy were less likely to report obtaining medication supplies. In conclusion, though most higher-risk individuals were aware of social distancing as a prevention strategy early in the outbreak, less than half reported enacting it, and racial disparities were apparent. Consistent messaging and the provision of tangible resources may improve future adherence to safety recommendations.

Older Adult Preferences of Mobile Application Functionality Supporting Medication Self-Management.

Health systems and insurers alike are increasingly interested in leveraging mHealth (mobile health) tools to support patient health-related behaviors including medication adherence. However, these tools are not widely used by older patients. This study explores patient preferences for functionality in a smartphone application (app) that supports medication self-management among older adults with multiple chronic conditions. We conducted six discussion groups in Chicago, Miami, and Denver (N = 46). English-speaking older adults (55 and older) who owned smartphones and took five or more prescription medicines were invited to participate. Discussions covered familiarity with and use of current apps and challenges with taking multidrug regimens. Participants reviewed a range of possible mobile app functions and were asked to give feedback regarding the acceptability and desirability of each to support medication management. Very few participants (n = 3) reported current use of a mobile app for medication support, although all were receptive. Challenges to medication use were forgetfulness, fear of adverse events, and managing medication information from multiple sources. Desired features included (1) a list and consolidated schedule of medications, (2) identification and warning of unsafe medication interactions, (3) reminder alerts to take medicine, and (4) the ability record when medications were taken. Features relating to refill ordering, pharmacy information, and comparing costs for medication were not considered to be as important for an app.

Literacy disparities in patient access and health-related use of Internet and mobile technologies.

BACKGROUND: Age and race-related disparities in technology use have been well documented, but less is known about how health literacy influences technology access and use. OBJECTIVE: To assess the association between patients' literacy skills and mobile phone ownership, use of text messaging, Internet access, and use of the Internet for health-related purposes. METHODS: A secondary analysis utilizing data from 1077 primary care patients enrolled in two, multisite studies from 2011-2013. Patients were administered an in-person, structured interview. RESULTS: Patients with adequate health literacy were more likely to own a mobile phone or smartphone in comparison with patients having marginal or low literacy (mobile phone ownership: 96.8 vs. 95.2 vs. 90.1%, respectively, P < 0.001; smartphone ownership: 70.6 vs. 62.5 vs. 40.1%, P < 0.001) and to report text messaging (78.6 vs. 75.2 vs. 53.1%, P < 0.001). They were also more likely to have access to the Internet from their home (92.1 vs. 74.7 vs. 44.9%, P < 0.001) and to report using the Internet for email (93.0 vs. 75.7 vs. 38.5%, P < 0.001), browsing the web (93.9 vs. 80.2 vs. 44.5%, P < 0.001), accessing health information (86.3 vs. 75.5 vs. 40.8%, P < 0.001), and communicating with providers (54.2 vs. 29.8 vs. 13.0%, P < 0.001). Relationships remained significant in multivariable analyses controlling for relevant covariates. CONCLUSIONS: Results reveal that literacy-related disparities in technology access and use are widespread, with lower literate patients being less likely to own smartphones or to access and use the Internet, particularly for health reasons. Future interventions should consider these disparities and ensure that health promotion activities do not further exacerbate disparities.

Comparative effectiveness of patient-centered strategies to improve FDA medication guides.

BACKGROUND: Med Guides are the only Food and Drug Administration-regulated source of written patient information distributed with prescriptions drugs. Despite their potential value, studies have found them to have limited utility. OBJECTIVE: To evaluate the effectiveness of patient-centered strategies for the design of Med Guides to improve comprehension. DESIGN: A cross-sectional, randomized trial. SETTING: Two primary care clinics in Chicago, Illinois; one based in a public university hospital and the other within a private academic medical center. PATIENTS: A total of 1003 adults aged 18-85 years. INTERVENTION: The format and layout of content from 3 typical Med Guides (by reading difficulty, length, exposure) were modified several ways to promote information accessibility. Working with patients, the 3 most preferred versions were evaluated. The first used 2 columns to organize content (Column), a second mimicked over-the-counter "Drug Facts" labeling (Drug Facts), and the third followed health literacy best practices using a simple table format (Health Literacy prototype). MEASURES: Tailored comprehension assessment of content from 3 representative Med Guides. RESULTS: Comprehension was significantly greater for all 3 prototypes compared with the current standard (all P<0.001). The Health Literacy prototype consistently demonstrated the highest comprehension scores, and in multivariable analyses, outperformed both the Drug Facts [ß=-4.43, 95% confidence interval (CI), -6.21 to -2.66] and Column (ß=-4.04, 95% CI, -5.82 to -2.26) prototypes. Both older age (older than 60 y: ß=-10.54, 95% CI, -15.12 to -5.96), low and marginal literacy skills were independently associated with poorer comprehension (low: ß=-31.92, 95% CI, -35.72 to -28.12; marginal: ß=-12.91, 95% CI, -16.01 to -9.82). CONCLUSIONS: The application of evidence-based practices to the redesign of Med Guides significantly improved patient comprehension. Although some age and literacy disparities were reduced with the Health Literacy format in particular, both older age and low literacy remained independently associated with poorer comprehension. More aggressive strategies will likely be needed to gain assurances that all patients are informed about their prescribed medications. TRIAL REGISTRATION: Clinical Trials.Gov #NCT01731405.

Missed Healthcare Visits During the COVID-19 Pandemic: A Longitudinal Study.

INTRODUCTION: Missed visits have been estimated to cost the U.S. healthcare system $50 billion annually and have been linked to healthcare inefficiency, higher rates of emergency department visits, and worse outcomes. COVID-19 disrupted existing outpatient healthcare utilization patterns. In our study, we sought to examine the frequency of missed outpatient visits over the course of the COVID-19 pandemic and to examine patient-level characteristics associated with non-attendance. METHODS: This study utilized data from a longitudinal cohort study (the Chicago COVID-19 Comorbidities (C3) study). C3 participants were enrollees in 1 of 4 active, "parent" studies; they were rapidly enrolled in C3 at the onset of the pandemic. Multiple waves of telephone-based interviews were conducted to collect experiences with the pandemic, as well as socio-demographic and health characteristics, health literacy, patient activation, and depressive and anxiety symptoms. For the current analysis, data from waves 3 to 8 (05/01/20-05/19/22) were analyzed. Participants included 845 English or Spanish-speaking adults with 1 or more chronic conditions. RESULTS: The percentage of participants reporting missed visits due to COVID-19 across study waves ranged from 3.1 to 22.4%. Overall, there was a decline in missed visits over time. No participant sociodemographic or health characteristic was consistently associated with missed visits across the study waves. In bivariate and multivariate analysis, only patient-reported anxiety was significantly associated with missed visits across all study waves. CONCLUSION: Findings reveal that anxiety was consistently associated with missed visits during the COVID-19 pandemic, but not sociodemographic or health characteristics. Results can inform future public health initiatives to reduce absenteeism by considering patients' emotional state during times of uncertainty.

Delayed opportunities for patient-provider communication about medication overuse headache: Mixed methods perspectives from patients and neurologists.

Objectives: Medication overuse headache (MOH) is a common, debilitating condition occurring when migraine patients overuse pain relief medications. We conducted a convergent mixed methods study examining patient-provider communication on MOH. Methods: Migraine patients were identified from one academic health center via electronic health records. Research staff recruited patients and administered a remote survey on MOH awareness, knowledge, and communication; descriptive and bivariate analyses were conducted. Neurologists from the same health center were invited to participate in qualitative interviews; analysis drew from the Rapid Identification of Themes from Audio Recordings procedures. A side-by-side comparison of results followed. Results: Participants included 200 patients and 13 neurologists. More than one third of patients (39.5 %) had never heard of 'medication overuse headache.' Among those who had, 38.4 % learned about MOH ≥ 5 years after their migraine diagnosis. Neurologists similarly reported limited patient awareness of MOH and suggested communication was provider-initiated, reactive to patient-reported symptoms and behaviors. Participants agreed MOH was described as a 'consequence' of frequent medication taking, though specific terminology varied with neurologists suggesting they choose terms they perceive to be easier to understand and less stigmatizing to patients. Neurologists felt they lacked effective patient education resources. Conclusions: Findings reveal delayed opportunities to inform patients about MOH. Standardized education supporting early preventive communication is needed, perhaps in primary care where many patients seek initial care for migraine symptoms.

Association between awareness and knowledge of medication-overuse headache with medication-taking behavior among adults with migraine.

Frequent use of pain relief medications among patients with migraine can result in disease worsening and medication-overuse headache (MOH), a painful and debilitating condition. We sought to conduct a cross-sectional survey among adult patients diagnosed with migraine to determine: 1) their awareness of MOH, and 2) their knowledge of the condition and its prevention, and 3) the association of these factors with actual use of pain relief medications. We recruited and interviewed 200 English-speaking adults with migraine who had a clinic visit with a neurologist or primary care provider within the past month. Patients were identified via an electronic health record query. Almost 40% of participants had never heard of the term 'medication-overuse headache.' In bivariate analyses, participants who were Black or Hispanic and those with limited health literacy were less likely to have heard of MOH. Participants scored an average of 2.1 (range: 0-3) on a MOH knowledge measure; older participants, those with limited health literacy, lower education, and little or no migraine-related disability demonstrated less knowledge. Almost a third (31.5%) of patients reported overusing pain relief medication and were at risk for MOH. Overuse was not significantly associated with MOH awareness, knowledge, or sociodemographic factors, but was related to greater migraine-related disability. Our findings suggest that patient awareness and knowledge of MOH is suboptimal, particularly among older adults, racial and ethnic minority groups, and those with limited health literacy. Interventions are needed to prevent MOH and better inform patients about risks associated with frequent use of pain relief medications.

Patient and clinician preferences for diabetes management among older adults with co-morbid HIV: A qualitative exploration.

BACKGROUND: Older adults with HIV are at increased risk of developing certain chronic health conditions including type 2 diabetes mellitus (T2DM). As the number and complexity of conditions increases, so do treatment and health care needs. We explored patient and clinician preferences for HIV+T2DM care and perceived solutions to improving care. METHODS: We conducted an exploratory qualitative study comprised of individual in-depth interviews. Participants included English-speaking patients aged 50 and older living with HIV and T2DM and infectious disease (ID) and primary care (PC) clinicians from a large academic health center in Chicago. Thematic analysis drew from the Framework Method. RESULTS: A total of 19 patient and 10 clinician participants were interviewed. Many patients reported seeking HIV and T2DM care from the same clinician; they valued rapport and a 'one-stop-shop'. Others reported having separate clinicians; they valued perceived expertise and specialty care. Nearly all clinicians reported comfort screening for T2DM and initiating first line oral therapy; ID clinicians reported placing referrals for newer, complex therapies. Patients would like educational support for T2DM management; clinicians would like to learn more about newer therapies and easier referral processes. CONCLUSIONS: Patient-centered care includes managing T2DM from a variety of clinical settings for individuals with HIV, yet strategies are needed to better support clinicians. Future research should examine how best to implement these strategies.

Rethinking adherence: a health literacy-informed model of medication self-management.

Medication adherence has received a great deal of attention over the past several decades; however, its definition and measurement remain elusive. The authors propose a new definition of medication self-management that is guided by evidence from the field of health literacy. Specifically, a new conceptual model is introduced that deconstructs the tasks associated with taking prescription drugs; including the knowledge, skills and behaviors necessary for patients to correctly take medications and sustain use over time in ambulatory care. This model is then used to review and criticize current adherence measures as well as to offer guidance to future interventions promoting medication self-management, especially among patients with low literacy skills.

What do healthy women know about the consequences of delayed childbearing?

Female fertility declines dramatically with age, and childbearing at older maternal ages has significant medical consequences for mother and infant that are well-known to health professionals. Despite this, the average maternal age in the United States continues to rise. Many factors likely contribute to this secular trend; to date, no research has examined whether American women are aware of the complications of deferring conception and how this correlates with health literacy. The purpose of this study was to evaluate women's knowledge of the implications of delaying pregnancy. A structured, in-person interview was administered to 300 women between 20 and 50 years of age attending 1 of 2 gynecologic clinics at a single institution. Demographic information, medical history, and gynecologic history were obtained; and participants answered questions about the implications of aging for fertility and pregnancy outcome. Health literacy and numeracy were assessed. Participants demonstrated knowledge deficits about the implications of aging on fertility and pregnancy, and many were unfamiliar with success rates of infertility treatments. Several demographic factors correlated with knowledge; health literacy and numeracy were both important predictive variables. To the authors' knowledge, this is the first study of women's knowledge about fertility, aging, and their health literacy. Awareness of the importance of health literacy and numeracy should inform future educational efforts about fertility.

Take-Wait-Stop: a patient-centered strategy for writing PRN medication instructions.

Recent studies have linked patient misunderstanding of label instructions for as needed (PRN) medications to dosing errors. This study conducted a preliminary field test of patient-centered PRN label instructions. Patients participated in a hypothetical dosing experiment and were randomized to a patient-centered label (referred to as "Take-Wait-Stop") or standard label. Participants were asked to demonstrate dosing the medicine over 24 hours. Three types of independent dosing errors were measured: (a) taking more than two pills at one time, (b) exceeding the maximum daily dose, and (c) waiting fewer than 4 hours between doses. Generalized linear models were used to assess the association between label type, health literacy, and sociodemographic characteristics. Participants' mean age was 39.8 years, 62.1% were female, 43.7% were White, and 72.4% had adequate literacy. Of participants, 31.8% who were shown the standard label demonstrated taking in excess of 6 pills in 24 hours compared with only 14.0% of participants who were shown the Take-Wait-Stop label (p = .05). Overall, only 1 person demonstrated he would take more than 2 pills in a single dose. Of the standard label group, 20.5% demonstrated dosing intervals of fewer than 4 hours compared with 23.3% of the Take-Wait-Stop label group (p=.75). In a multivariate model, participants who were exposed to the standard label were 2.5 times more likely to exceed the recommended maximum daily dose (95% CI [1.05, 7.70], p=.03). The Take-Wait-Stop label was beneficial in preventing participants from exceeding the maximum dose in 24 hours, although it did not significantly reduce other dosing errors.

A chatbot for hypertension self-management support: user-centered design, development, and usability testing.

Objectives: Health-related chatbots have demonstrated early promise for improving self-management behaviors but have seldomly been utilized for hypertension. This research focused on the design, development, and usability evaluation of a chatbot for hypertension self-management, called "Medicagent." Materials and Methods: A user-centered design process was used to iteratively design and develop a text-based chatbot using Google Cloud's Dialogflow natural language understanding platform. Then, usability testing sessions were conducted among patients with hypertension. Each session was comprised of: (1) background questionnaires, (2) 10 representative tasks within Medicagent, (3) System Usability Scale (SUS) questionnaire, and (4) a brief semi-structured interview. Sessions were video and audio recorded using Zoom. Qualitative and quantitative analyses were used to assess effectiveness, efficiency, and satisfaction of the chatbot. Results: Participants (n = 10) completed nearly all tasks (98%, 98/100) and spent an average of 18 min (SD = 10 min) interacting with Medicagent. Only 11 (8.6%) utterances were not successfully mapped to an intent. Medicagent achieved a mean SUS score of 78.8/100, which demonstrated acceptable usability. Several participants had difficulties navigating the conversational interface without menu and back buttons, felt additional information would be useful for redirection when utterances were not recognized, and desired a health professional persona within the chatbot. Discussion: The text-based chatbot was viewed favorably for assisting with blood pressure and medication-related tasks and had good usability. Conclusion: Flexibility of interaction styles, handling unrecognized utterances gracefully, and having a credible persona were highlighted as design components that may further enrich the user experience of chatbots for hypertension self-management.
