Designing and Evaluating a Patient-Driven Application for Patients with Primary Brain Tumors
From the time of diagnosis through treatment and follow-up, patients with primary brain tumors and their caregivers face a multitude of challenges and uncertainties. Many of these challenges and uncertainties have been attributed to the complexities of these rare and deadly tumors, coupled with the fact that there is still ...
On Biological Network Visualization: Understanding Challenges, Measuring the Status Quo, and Estimating Saliency of Visual Attributes
Biomedical research increasingly relies on the analysis and visualization of a wide range of collected data. However, for certain research questions, such as those investigating the interconnectedness of biological elements, the sheer quantity and variety of data results in rather uninterpretable—this is especially true for ...
What Difference Does a Form Make: Redesign and Evaluation of a Form for Documenting In-Hospital Cardiac Arrest
(2013-07-23)
The real-time documentation of medications and procedures is an essential part of managing patient care during in-hospital "code blue" cardiac arrest emergencies. Care providers have voiced dissatisfaction with the existing code blue documentation form. To address this problem, a mixed-methods needs assessment was used to ...
Supporting collaborative clinical trial protocol writing through an annotation design
(2005)
Clinical trial protocols are important documents that guide clinical research. Modern protocol development requires collective expertise from a group of Loosely-Coupled protocol writers, who work across distances and time zones. Email has been the primary communication tool for these protocol writers. Unfortunately, it ...
Performance evaluation of a natural language processing tool to extract infectious disease problems
(2013-11-14)
Use of a complete problem list can benefit patient care, quality improvement initiatives, and research activities. However, it can be time consuming for physicians to enter the correct encoded problem from a standardized terminology. I evaluated Discern nCode, the natural language processing (NLP) system embedded in Cerner ...
Evaluation of a Computer-Based System using Cell Phones for HIV positive people in Peru
(2012-09-13)
HIV is one of the biggest infectious killers worldwide. To prevent disease progression and avoid development of resistant strains to HIV, people living with HIV must adhere to complicated antiretroviral therapy (ART). Yet, in Peru, where ART has recently been introduced, adherence to HIV treatment has not yet been addressed ...
Forecasting Medical Patient Length of Stay at Presentation in an Emergency Department Using Machine Learning
Emergency Department (ED) overcrowding has become common across the globe. Among many proposed measures, ED length of stay (LOS) remains the most commonly reported outcome resulting from overcrowding. Predicting patients’ ED LOS, especially as early as at presentation, could provide valuable information for both patients and ...
Using personal health records to promote patient activation in the homebound older adult population
Patient activation, or an individual’s willingness and ability to take actions to maintain their health and wellness, is a primary component of the patient-centered health system. Activated patients are more likely to report positive experiences with their medical providers, have better health outcomes, and spend less on ...
Creating a Smartphone Application for Image-Assisted Dietary Assessment among Older Adults with Type 2 Diabetes
In the United States, the population of those aged 65 or over numbered 44.7 million in 2013 and is anticipated to reach approximately 74 million people by 2030. More than one in four people in the United States aged 65 years and older have diabetes. For diabetes care, medical nutrition therapy (MNT) is recommended as a ...
Extraction of Clinical Timeline from Discharge Summaries using Neural Networks
Discharge summaries are a concise representation of the most important bits of information about a patient’s time in the hospital. Converting the free-text into a clinical timeline can facilitate accurate assimilation of information by physicians and the structured data can be used to populate knowledge bases, in clinical ...
