Background. Medical and interventional therapies for older adults with acute myocardial infarction (AMI) reduce mortality and improve outcomes in selected patients, but there are also risks associated with treatments. Shared decision making (SDM) may be useful in the management of such patients, but to date, patients’ and cardiologists’ perspectives on SDM in the setting of AMI remain poorly understood. Accordingly, we performed a qualitative study eliciting patients’ and cardiologists’ perceptions of SDM in this scenario. Methods. We conducted 20 in-depth, semistructured interviews with older patients (age ≥70) post-AMI and 20 interviews with cardiologists. The interviews were transcribed and analyzed using ATLAS.ti. Two investigators independently coded transcripts using the constant comparative method, and an integrative, team-based process was used to identify themes. Results. Six major themes emerged: 1) patients felt their only choice was to undergo an invasive procedure; 2) patients placed a high level of trust and gratitude toward physicians; 3) patients wanted to be more informed about the procedures they underwent; 4) for cardiologists, patients’ age was not a major contraindication to intervention, while cognitive impairment and functional limitation were; 5) while cardiologists intuitively understood the concept of SDM, interpretations varied; and 6) cardiologists considered SDM to be useful in the setting of non-ST elevated myocardial infarction (NSTEMI) but not ST-elevated myocardial infarction (STEMI). Conclusions. Patients viewed intervention as “the only choice,” whereas cardiologists saw a need for balancing risks and benefits in treating older adults post-NSTEMI. This discrepancy implies there is room to improve communication of risks and benefits to older patients. A decision aid informed by the needs of older adults could help to better convey patient-specific risk and increase choice awareness.
Undergraduate students participating in the UCLA Undergraduate Research Consortium for Functional Genomics (URCFG) have conducted a two-phased screen using RNA interference (RNAi) in combination with fluorescent reporter proteins to identify genes important for hematopoiesis in Drosophila. This screen disrupted the function of approximately 3500 genes and identified 137 candidate genes for which loss of function leads to observable changes in the hematopoietic development. Targeting RNAi to maturing, progenitor, and regulatory cell types identified key subsets that either limit or promote blood cell maturation. Bioinformatic analysis reveals gene enrichment in several previously uncharacterized areas, including RNA processing and export and vesicular trafficking. Lastly, the participation of students in this course-based undergraduate research experience (CURE) correlated with increased learning gains across several areas, as well as increased STEM retention, indicating that authentic, student-driven research in the form of a CURE represents an impactful and enriching pedagogical approach.
Background: Many patients hospitalized with non-ST elevation myocardial infarction (NSTEMI) are older adults (age 75 and older), in whom invasive coronary angiography confers potential benefits but also higher risks than the general population. Our goal was to therefore develop a patient decision aid (PtDA) to assist with shared decision making between cardiologists and older adults with this condition.
Methods: We followed International Patient Decision Aid Standards to develop the NSTEMI Decide PtDA. The initial prototype was based on structured interviews from 20 patients and 20 clinicians. Risks and benefits of invasive coronary angiography were derived from the available literature in older adults, with an emphasis on findings from randomized trials. The PtDA was then revised through an iterative, user-centered design approach with rapid prototyping using input from both clinician and patients to meet the needs of both stakeholders.
Results: The PtDA went through 8 iterations. The final decision aid was 11 pages and included background information (6 pages), explanation of benefits and risks (4 pages), and a summary (1 page). Large font (≥26 point) was used to accommodate visual difficulties. Language was tailored to an 8th grade reading level. Based on the best available literature, we included benefits of invasive coronary angiography (recurrent myocardial infarction, repeat revascularization) and risks (stroke, bleeding, acute kidney injury). The final PtDA was converted to a mobile health application to increase usability on portable digital devices in the clinical setting.
Conclusions: We developed the first PtDA tailored to older adults hospitalized with NSTEMI. This PtDA will be prospectively tested to evaluate dimensions including feasibility of use, satisfaction with care, medical knowledge, and decisional conflict.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
