BACKGROUND Supportive oncology practice can be enhanced by the integration of a brief and validated electronic patient‐reported outcome assessment into health record (EHR) clinical workflow. METHODS Six hundred thirty‐six women receiving gynecologic outpatient care received instructions to complete assessments through Epic MyChart, an EHR patient communication portal. Patient Reported Outcomes Measurement Information System (PROMIS) computer adaptive tests (CATs) were administered assess...

Background Routine cognitive screening is essential in the early detection of dementia, but time constraints primary care settings often limit clinicians’ ability to conduct screenings. MyCog Mobile a newly developed system that patients can self-administer on their smartphones before visit, which help save clinics’ time, encourage broader practices, and increase decline. Objective The goal this pilot study was examine feasibility, acceptability, initial psychometric properties Mobile....

Abstract Objective: The ability to remotely monitor cognitive skills is increasing with the ubiquity of smartphones. Mobile Toolbox (MTB) a new measurement system that includes measures assessing Executive Functioning (EF) and Processing Speed (PS): Arrow Matching, Shape-Color Sorting, Number-Symbol Match. purpose this study was assess their psychometric properties. Method: MTB were developed for smartphone administration based on constructs measured in NIH Toolbox® (NIHTB). Psychometric...

Introduction Annual cognitive screening in older adults is essential for early detection of impairment, yet primary care settings face time constraints that present barriers to routine screening. A remote screener completed on a patient’s personal smartphone before visit has the potential save clinics time, encourage broader practices and increase decline. MyCog Mobile promising new smartphone-based app settings. We propose combined construct clinical validation study Mobile. Methods...

Background: Patient-reported outcomes are increasingly utilized in routine orthopedic clinical care. Computer adaptive tests (CATs) from the Patient-Reported Outcomes Measurement Information System (PROMIS) offer a brief and precise assessment that is well suited for collection within busy environments. However, software apps support administration scoring of CATs, provide immediate access to patient-reported outcome (PRO) scores, minimize clinician burden not widely available.

Early identification of cognitive impairment (CI), including Alzheimer's disease and related dementias (ADRD), is a top public health priority. Yet, CI/ADRD often undetected underdiagnosed within primary care settings, in disparate populations. The MyCog paradigm an iPad-based, self-administered, validated assessment based on the National Institutes Health (NIH) Toolbox Cognition Battery coupled with clinician decision-support tools that specifically tailored for detection diverse, settings....

Abstract Validation of the Mobile Toolbox Faces and Names associative memory test is presented. Ninety‐two participants self‐administered in‐person; 956 remotely but took convergent measures in person; 123 twice, 14 days apart. Internal consistency (.76–.79) test–retest reliability (ICC = .73) were acceptable. Convergent validity with WMS‐IV Verbal Paired Associates was satisfactory (immediate .54; delayed .58). The findings suggest administered a reliable instrument.

Objectives: To help promote early detection of cognitive impairment in primary care, MyCog Mobile was designed as a screener that can be self-administered remotely on personal smartphone. We explore the potential utility care by comparing to commonly used screener, Mini-Cog. Methods: A sample 200 older adults 65+ years (mean age = 72.56 years), completed Mini-Cog and Mobile, which includes 2 memory measures executive functioning measures. logistic regression model conducted predict failing...

Air pollutants concentrations reach high levels in developing countries. However, due to the lack of measurements, too often, this problem remains unseen. In Ecuador, top-down inventories classify on-road vehicles as main source air pollution, well cities Ecuador. order unveil importance these sources we developed a detailed vehicular emission for Ecuador at province and monthly level.

Abstract Background Early identification of cognitive impairment (CI), including Alzheimer’s disease and related dementias (ADRD), is a top public health priority. Yet in primary care settings that manage the most community‐dwelling older adults, less than half patients with any CI are detected and/or diagnosed. Among community centers serve marginalized patients, rates detection may be far lower. To address this, we sought to test care‐based strategy (‘MyCog’) improve as part an...
