Purpose: Electrocardiography (ECG)-derived machine learning models can predict echocardiography (echo)-derived indices of systolic or diastolic function. However, systolic and diastolic dysfunction frequently coexists, which necessitates an integrated assessment for optimal risk-stratification. We explored an ECG-derived model that emulates an echo-derived model that combines multiple parameters for identifying patient phenogroups at risk for major adverse cardiac events (MACE).

Methods: In this substudy of a prospective, multicenter study, patients from 3 institutions (n = 727) formed an internal cohort, and the fourth institution was reserved as an external test set (n = 518). A previously validated patient similarity analysis model was used …

A Physical Therapy Mobility Checkup For Older Adults: Feasibility And Participant Preferences From A Discrete Choice Experiment, Dalerie Lieberz, Hannah Borgeson, Steven Dobson, Lindsey Ewings, Karen Johnson, Kori Klaysmat, Abby Schultz, Rachel Tasson, Alexandra L. Borstad

Journal of Patient-Centered Research and Reviews

Purpose: Physical performance measures, like walking speed, identify and predict preclinical mobility disability but are rarely used in routine medical care. A preventive model of care called Mobility Checkup is being designed to reduce mobility disability in older adults. This study had two purposes: 1) determine feasibility and outcomes of the Mobility Checkup, and 2) identify preferences of older adults regarding this model of care using a discrete choice experiment.

Methods: Adults over 55 years of age were recruited from the community. In the study’s first phase, participants completed a Mobility Checkup, with feasibility evaluated using 6 criteria. In the …

Preprocedure Covid-19 Testing In Early Phase Of Pandemic, Renuka Jain, Bradley Kruger, Robert Citronberg, Stacie Kroboth, Ana Cristina Perez Moreno, Bijoy K. Khandheria

Journal of Patient-Centered Research and Reviews

The COVID-19 pandemic led to a nationwide shutdown of elective medical procedures. Upon resumption of services, preprocedure nasopharyngeal swab testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was introduced for all patients requiring surgical or other aerosol-generating procedures. We investigated preprocedure COVID-19 testing in one of the largest U.S. health systems. Patients included in this retrospective, observational study were asymptomatic and scheduled for a procedure or surgery. All patients underwent a nasopharyngeal swab test for SARS-CoV-2 performed 24–72 hours prior to a planned procedure. Clinical demographics, type of procedure, test results, and subsequent procedure status were evaluated. Of 38,608 …

Seroprevalence Of Sars-Cov-2 Antibody In Echocardiography And Stress Laboratory, Renuka Jain, Stacie Kroboth, Denise Ignatowski, Bijoy K. Khandheria

Journal of Patient-Centered Research and Reviews

Purpose: Transesophageal echocardiography is an aerosol-generating procedure, and exercise stress testing is a potentially aerosol-generating activity. Concern has been raised about heightened risk of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among health care personnel participating in these procedures. We aimed to investigate the prevalence of past coronavirus disease 2019 (COVID-19) infection in echocardiography and stress laboratory staff.

Methods: All staff who worked in the echocardiography and stress laboratories of one high-traffic urban hospital from March 15, 2020, to June 15, 2020, were asked to voluntarily participate. Those willing to participate were consented, and past COVID-19 infection was …

Listening To The Patient: A Typology Of Contextual Red Flags In Disease Management Encounters, Amy E. Binns-Calvey, Gunjan Sharma, Naomi Ashley, Brendan Kelly, Frances M. Weaver, Saul J. Weiner

Journal of Patient-Centered Research and Reviews

Purpose: Patients send clues, often unwittingly, when they are grappling with a life challenge that complicates their care. For instance, a patient may lose control of a previously well-managed chronic condition or start missing appointments. When explored, these clues help clinicians uncover the life circumstance impacting the individual’s ability to manage their health and health care. Such clues are termed “contextual red flags.” Effective care requires recognizing them, asking about them, and customizing the care plan where feasible. We sought to develop a typology of contextual red flags by analyzing audio recordings along with the medical records of encounters between …

Use Of Urine Antigen Testing For Blastomyces In An Integrated Health System, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Purpose: Blastomycosis, an endemic fungal infection, mimics many other diseases. We explored the use of Blastomyces urine antigen (BuAg), reportedly the most sensitive noninvasive test, in clinical practice and compared it to other noninvasive tests.

Methods: A total of 836 BuAg tests performed on unique patients (first test only) at one large integrated health system from June 2013 to May 2016 were retrospectively reviewed to examine test characteristics and demographic features. Of these, 100 cases from 2015, a year containing a large local blastomycosis outbreak, were randomly selected for detailed analysis.

Results: Demographics for the BuAg-tested population: mean age 54.9 …

Relative Associations Of Age, Height, And Weight On Sinus Of Valsalva And Mid-Ascending Aorta: An Imaging And Epidemiology Study, Mirza Nubair Ahmad, Syed Haris Pir, Mirza Mujadil Ahmad, Sharmeen Hussaini, Bijoy K. Khandheria, A. Jamil Tajik, Khawaja Afzal Ammar

Journal of Patient-Centered Research and Reviews

Background: Prior studies show ascending aorta diameter varies with age, height and weight, but they did not evaluate relative influence of these variables on aortic diameter. Since height is genetically determined, and genetic disorders like Marfan syndrome are predominantly associated with sinus of Valsalva (SOV) dilation, we hypothesized height may have stronger association with SOV.

Purpose: Based on anecdotal observation, since age, weight and obesity are acquired attributes, we hypothesized age, weight and body mass index may have greater association with mid-ascending aorta (MAA) diameter, even in normal patients.

Methods: We evaluated echocardiographic studies of patients ≥ 15 years old …
