J. S. Choi is a physician of internal medicine and clinical informatics.

Employment

Kettering Medical Center
Internal Medicine Residency

After graduation, Joshua has been practicing medicine, as a resident physician under the supervision of attending physicians at Kettering Medical Center, Sycamore Medical Center, and in the Sycamore Primary Care Clinic. His residency program gives in-depth postgraduate training, as a requirement to obtaining an unrestricted license to practice medicine in the United States.

Education

Saint Louis University College of Medicine
Doctor of Medicine

First extra academic year was voluntarily requested from school, to gain further bioinformatics research and elective clinical rotations, before deciding on speciality for residency for Psychiatry. Second extra year was voluntarily requested from school: after soliciting faculty feedback that suggested a mismatch with Psychiatry, specialty was pivoted to Internal Medicine. Extra year was composed of continuous Internal Medicine rotations of direct patient care, followed by successful NRMP match for Internal Medicine in 2018.

University of Arizona College of Medicine
Bachelor of Science

Major in Physiology • Double minor in Computer Science and Chemistry.
Magna cum laude. GPA 3.98.

Research

Memorine: Spaced-repetition software using annotated educational literature is a highly interactive intervention for persistent medical knowledge

Fred Buckhold, III, MD • SLU SOM Department of Internal Medicine, Division of General Internal Medicine

An essential component of medical competency is declarative medical knowledge. However, much of medical education’s value is nullified by the natural exponential decay of that knowledge. Cognitive psychology has well established that simply testing active recall may be more effective at maintaining declarative knowledge than passive didactics, study, reading, and review. This testing effect is strengthened even further by spaced repetition. However, testing with spaced repetition has several factors that make it difficult to effectively implement in medical education. These hinderances could be mitigated by applying properly designed spaced-repetition software (SRS) to the existing corpus of high-quality medical literature published on the web.

Such an SRS is being developed for physicians’ academic use. Codenamed Memorine, the software will be first privately released as an alpha-stage minimum viable product, in the form of a web-browser extension. It is hoped that, as highly interactive educational interventions, Memorine and its successors will serve as useful adjuncts to existing medical-educational methods, alleviate the burden of knowledge maintenance on physicians, and improve clinician performance and patient outcomes.

Practice guidelines of BPSD pharmacologic management: a review

George T. Grossberg, MD • SLU SOM Department of Neurology & Psychiatry

A systematic literature review was performed over recently published practice guidelines on the pharmacologic management of behavioral and psychiatric symptoms of dementia. The publication process was placed on hold following pivot from Psychiatry to Internal Medicine.

Patient-data displays: visual presentation and design

David Burroughs, PhD • 
SLU Center for Outcomes Research

This project compiled existing information on the visual design of patient-data displays. Information included methods of presentation and visualization of patient data to healthcare providers and how these methods affect clinical decision making, diagnosis, medical errors, and medical outcomes. The project culminated in an audiovisual presentation.

Meaningful-use standards for pediatric electronic health record systems

Feliciano B. Yu, Jr., MD • Washington University in St. Louis • St. Louis Children’s Hospital


This project consolidated several standards of meaningful-use requirements for electronic medical records’ user interfaces into a single database. It focused on requirements from the Children’s EHR Format, HL7, and NIST 7865 standards.


Patient electronic-health-record programmatic data analysis

Allan Wachter, MD

Data analysis was performed on longitudinal patient data on behalf of A. Wachter in an retrospective study for predicting asthma with the United States Navy. A computer program was developed to clean, normalize, and combine heterogenous patient data from several independent sources: the US Navy, the US Department of Veterans Affairs, and several pharmaceutical companies.
