Introduction: It is unknown how comorbid diagnoses affect patients’ disease-specific knowledge or how patients’ health literacy or numeracy affects this relationship. In patients with atrial fibrillation (AF), comorbidities can be quantified by the CHA 2 DS 2 -VASc score. We explore the association of AF/stroke knowledge with CHA 2 DS 2 -VASc score, health literacy, and numeracy for usual care participants in the multi-center Randomized Evaluation of Decision Support Interventions for Atrial Fibrillation (RED-AF) trial evaluating decision aids to initiate (initiation cohort) or continue (monitor cohort) oral anticoagulation (OAC) in AF patients. Methods: This study was conducted at six academic medical centers in the United States. Participants were aged ≥18, diagnosed with non-valvular AF, and at risk for stroke (CHA 2 DS 2 -VASc ≥1 for men, ≥2 for women). Patient demographics were obtained via questionnaires after a baseline clinical encounter; knowledge was evaluated by patient responses to 7 questions about OAC and AF. Health literacy was measured by a validated self-reported screening tool; numeracy by a validated subjective numeracy scale; CHA 2 DS 2 -VASc was calculated from medical records. We applied generalized estimating equations for a binomial outcome to jointly relate patient knowledge to CHA 2 DS 2 -VASc score, health literacy and numeracy, controlling for 5 additional patient factors and accounting for clustering by clinician. Results: We report on 306 patients randomized to the usual care group across six participating sites. Average age 68.7 9, 61.6% male, mean CHA 2 DS 2 -VASc 2 1.5. Patient knowledge was independently associated with numeracy (5% higher odds of correct response per 1 unit increase in numeracy, 95% CI 0-10%, p=0.05) and membership in the monitor cohort (40% odds of correct response, 4-89%, p=0.03) but not health literacy or increased stroke risk. Conclusion: In the RED-AF study , although health literacy and increasing stroke risk were not independently associated with patient knowledge about AF, numeracy had a minimal positive association. Those already on OAC had greater disease knowledge than patients newly starting OAC. These results suggest a need to broadly increase patient education regardless of baseline comorbidity burden and degree of health literacy. Future studies should be performed to better understand other factors that drive patient knowledge regarding AF and stroke.

ABSTRACT Background Guidelines recommend primary care practitioners (“PCPs”) engage women ≥ 75 years in shared decision‐making (SDM) around mammography screening. Therefore, we aimed to develop a web‐based conversation aid about mammography screening for women ≥ 75 using output from established simulation models to provide screening outcomes based on > 23,000 combinations of individual women's health and breast cancer risk factors. Methods We used an end‐user centered design approach to develop a prototype web‐based conversation aid incorporating feedback. From July 2023 to April 2024, 10 PCPs from a Boston‐area health system and a safety‐net hospital used the prototype aid during encounters with women ≥ 75 without breast cancer or dementia ( n = 30; 1–5 patients per PCP). We observed aid use and assessed clinician effort to involve patients in SDM using OPTION5 (assesses five components of SDM, scores range 0–100). We surveyed PCPs and patients about the aid's acceptability. Patients completed the SDM‐process scale (scores range 0–4) to rate the SDM quality experienced. Participants' comments were subject to thematic analysis. Results Of 10 PCP ‐participants, seven were female and four were community‐based. Of 30 patient‐participants, 22 (73%) were non‐Hispanic White, 9 (30%) had ≥ 2 Charlson comorbidities and mean age was 78.5 years ( SD 2.8). Nine PCPs agreed that the aid helped them with SDM and was easy‐to‐use; six felt it had too much information; and seven planned to continue using the aid. Patients rated the SDM ‐process highly (scores = 3.0 [ SD 0.9]) and we observed high SDM (mean OPTION5 = 77.9 [ SD 20.6]). Participants felt the aid was “empowering” and “helpful for decision‐making.” After SDM discussions, seven patients intended to stop screening, nine to screen less frequently, and 14 to continue screening regularly. Conclusions We developed a novel conversation aid that supports SDM about mammography screening with women ≥ 75 years. Lessons learned will guide revisions of a final tool for testing in a clinical trial.

Importance The increasing use of glucagon-like peptide-1 receptor agonists (GLP-1RA) demands a better understanding of their association with thyroid cancer. Objective To estimate the risk of incident thyroid cancer among adults with type 2 diabetes being treated with GLP-1RA vs other common glucose-lowering medications. Design, Setting, and Participants This was a prespecified secondary analysis of a target trial emulation of a comparative effectiveness study using claims data for enrollees in commercial, Medicare Advantage, and Medicare fee-for-service plans across the US. Eligible participants were adults with type 2 diabetes at moderate risk for cardiovascular disease and without history of thyroid cancer who had newly filled prescriptions for GLP-1RA, sodium-glucose cotransporter 2 inhibitor (SGLT2i), dipeptidyl peptidase-4 inhibitor (DPP4i), or sulfonylurea from January 1, 2014, to December 31, 2021. Data were analyzed February 1 to October 31, 2024. Main Outcomes and Measures Overall and piecewise (<1, 1-2, and ≥2 years since treatment initiation) hazard ratios (HRs) for thyroid cancer with use of GLP-1RA vs the other 3 drug classes were estimated using inverse propensity score weighted Cox proportional hazards models. Modified intention-to-treat (mITT) (primary) and as-treated (sensitivity) analyses were performed. Results Of 351 913 patients (mean [SD] age, 65.3 [8.5] years; 173 391 [49.3%] females and 178 522 [50.7%] males), 41 112 started treatment with GLP-1RA; 76 093, with DPP4i; 43 499, with SGLT2i; and 191 209, with sulfonylurea therapy. The numbers of patients diagnosed with thyroid cancer were 69 (0.17%) in the GLP-1RA group, 172 (0.23%) in the DPP4i group, 72 (0.17%) in the SGLT2i group, and 381 (0.20%) in the sulfonylurea group. In the mITT analysis, GLP-1RA initiation was not significantly associated with increased overall risk for thyroid cancer compared to the other 3 diabetes drugs (HR, 1.24; 95% CI, 0.88-1.76). However, the risk for thyroid cancer was significantly higher within the first year after GLP-1RA initiation (HR, 1.85; 95% CI, 1.11-3.08) and was amplified in the overall as-treated analysis that censored patients when therapy was discontinued or another medication was added (HR, 2.07; 95% CI, 1.10-3.95). Conclusions and Relevance This secondary analysis of a target trial emulation of a comparative effectiveness study found that despite the low absolute risk of thyroid cancer among patients receiving GLP-1RA therapy, there was an increased risk of new thyroid cancer diagnoses within the first year of GLP-1RA initiation compared to 3 other diabetes drugs. This finding may have been due to enhanced early detection; therefore, further research is necessary to understand the underlying causes of this association.

Abstract Objective To evaluate the effectiveness of multiple decision aid strategies in promoting high quality shared decision making for prevention of stroke in patients with non-valvular atrial fibrillation. Design Cluster randomized controlled trial. Setting Six academic medical centers in the United States. Participants Patient participants were aged ≥18 with a diagnosis of non-valvular atrial fibrillation, at risk for stroke (CHA 2 DS 2 -VASc ≥1 for men, ≥2 for women), and scheduled for a clinical appointment to discuss stroke prevention strategies. Participating clinicians were those who manage stroke prevention strategies for participating patients. Intervention Patients were randomized to use a patient decision aid or usual care; clinicians were randomized to use an encounter decision aid or usual care with all participating patients. Main outcome measures Primary outcome measures were quality of shared decision making measured by OPTION12, knowledge of atrial fibrillation and its management, and decisional conflict. Results 1117 participants across six sites were included in the analysis. Compared with usual care, the combined use of both the patient decision aid and the encounter decision aid improved the quality of shared decision making (adjusted mean difference 12.1 (95% confidence interval (CI) 8.0 to 16.2; P<0.001), improved patients’ knowledge (odds ratio 1.68 (95% CI 1.35 to 2.09; P<0.001), and reduced patients’ decisional conflict (adjusted mean difference −6.3 (95% CI −9.6 to −3.1; P<0.001). Statistically significant improvements were also observed with the encounter decision aid alone versus usual care for all three outcomes and with the patient decision aid alone versus usual care for quality of shared decision making and knowledge. No important differences were observed in treatment choices for stroke prevention or in participants’ satisfaction. No statistically significant difference in the length of visit across study groups was detected. Conclusion Patients who received any decision aid (encounter decision aid, patient decision aid, or both) had lower decisional conflict, better shared decision making, and greater knowledge than those receiving no decision aid, except for the effect of the patient decision aid on decisional conflict, which did not reach statistical significance. The study establishes that use of either pre-visit or in-visit decision aids individually or in combination is advantageous compared with usual care.

Abstract The demands associated with ongoing disease management may overwhelm middle aged and older adults living with two or more chronic conditions. Treatment burden refers to both (a) the numerous demands—such as the time and costs of travel to clinical appointment, administrative burden, and coordinating fragmented care—healthcare makes on patients and (b) the negative impact on the patient’s wellbeing. We evaluated data from respondents of the treatment burden experimental module included in the 2022 Health and Retirement Study data collection wave (N=1,888). We analyzed responses to the 15-item Treatment Burden Questionnaire (TBQ; 15 questions scored 0-10; total sum 0-150; &gt;59 considered unsustainable burden). We compared mean total TBQ score by sociodemographic and multimorbidity combination groups using either a t-test (among 2 groups) or ANOVA (among &gt;2 groups). We compared sustainability across groups using a chi-square test. Respondents (mean 69 years; 62% female, 71% living with 2+ chronic conditions) had a mean TBQ score of 20.3/150 (SD 22.7) with 125 (6.6%) reporting unsustainable burden. Administrative and financial tasks and lifestyle changes were the most burdensome activities. Unsustainable burden was significantly more likely among younger (51-64 vs. older), lower educated (&lt; high school vs. ≥high school), and Black and Latino (vs. non-Latino White) respondents, and in those living with 2+ chronic conditions. In this nationally-representative sample of US adults, participants reported less treatment burden than previously reported in international studies. Certain sociodemographic groups reported high and unsustainable burden of treatment, informing future interventions to reduce treatment burden in mid and late life.
