Whitepaper - MedNexus for Physicians

Physicians are overwhelmed by the large volume of new medical information being published. If a physician wanted to keep up with primary care literature, it would require 29 hours of reading per week. Current search tools are ill-suited for finding relevant medical information due to the high volume of results. MedNexus proposes a solution using a semantic search engine and machine learning to deliver the most pertinent results tailored to a physician's specialty, cutting through the noise. MedNexus aims to save physicians time by providing a centralized platform to access medical journals, guidelines and other sources.

Physician and Medical Information Overload What is the solution?
1 Medicine is evolving quickly and online resources have become increasingly important to medical professionals and patients. A 2006 study by MaxMD found that US physicians spend at least 50 minutes per night online researching disease information, drug information, and to a lesser degree, continuing medical education information1 . Online medical resources are now a central component of healthcare delivery. "Online medical resources are now a central component of healthcare delivery." Nine out of ten physicians believe that enhanced access to online medical information has improved quality of care2 . MedNexus Whitepaper: Physicians and Information Overload
Problem: Information Overload "Physicians, like patients, are inundated with information and find it difficult to keep up with the important developments in their field." The main source of new relevant medical findings is the rapidly expanding research literature. According to a study published in the Journal of Medical Library Association in 2004, if a physician was to keep up on the latest findings in primary care, it would require 29 hours of reading a week3 . This problem has only gotten worse in the intervening years, especially as new scientific research is being published at an exponential rate. To illustrate this trend, PubMed - the National Library of Medicine’s database -now indexes over 1 million articles a year. With new discoveries are Question: How often do you use the following sources to gain information used to diagnose, treat and care for patients?6 made at an exponential rate, the half-life of medical information being seven years. Physicians do not have enough time to parse the volume of published research and often resort to educating themselves through dispersed and unreliable channels, such as Pubmed, Google searches and marketing material from Life Science companies5 . Current popular search tools are ill-suited for finding medical information due to the high volume and lack of relevance of the search results. 2 Wolters Kluwer Health 2013 Physician Outlook Survey.

What is the solution? Get the information you need when you need it: MedNexus Whitepaper: Physicians and Information Overload 3 A semantic search engine that captures the user’s intent. An application that delivers the most pertinent and important content. The application would personalize the results to the physician’s profile. The application can cut through the noise of the abundantly available medical information while maintaining diversity of sources. Allows physicians to most efficiently use their existing journal subscriptions in one platform 1. 2. 3. 4. 5.
A semantic search engine is a smart search engine. It uses the context and the definition of the search term to bring more relevant results to the physician. Essen- tially, the semantic search engine discerns a physi- cian's intent in searching for a medical case or concept. For example, if the user has combined their search with the terms “symptoms” or “treatment”, it can discern that the person has a specific medical case in mind. However, if a person has been searching for a rare protein, this is more likely a research question. "A semantic search engine that captures the user’s intent." keyword search MedNexus Whitepaper: Physicians and Information Overload 4 CONTEXT SEMANTICS
To help physicians quickly access the most relevant information, an application would rely on models that assess the clinical impact of medical research and generate a ranking, much like Google PageRank. This ranking would allow the physician to find the most relevant results first — saving them valuable time. The application has a complete body of information. The model sifts through “features” of published research - qualitative ones such as the title, abstract, authors, and quantitative ones such as citations, downloads - and searches for patterns that indicate clinical usefulness. The application tracks the latest research develop- ments and their corresponding clinical relevance. The application would take new publications from the top journals and run them through the model to determine the work’s clinical relevance. The application finds the most relevant information for physicians quickly. The application would deter- mine the most relevant search results by combining the degree of matching on the user's input along with the clinical relevance score of the content item. “An application that delivers the most pertinent and important content.” MedNexus Whitepaper: Physicians and Information Overload 5
The application takes into account the physician’s background to deliver the most relevant results. For example, if a physician self-identifies as an Emergen- cy Physician, we would provide content that is tailored to Emergency Medicine and refine the search results based on crowdsourced data from other Emergency Physicians. The application can identity which material many physicians find useful. Out of the returned results for a search, which results would a roomful of physicians think are the most useful? The model would simulate how they would do this without having them all in the same room. The application would have crowd-sourcing capabil- ities. The platform would track various user actions such as expands, bookmarks, shares, removes, opens and even implicit actions like the length of time spent on a screen or an entry. These actions can then be used to boost or demote content for each search term, community, or person. For example, a search for “heart attack treatment” where everyone clicks on the 4th item displayed would boost the 4th item upwards towards 1st, and the 1st item downwards. “The application would personalize the results to the physician’s profile.” MedNexus Whitepaper: Physicians and Information Overload 6
Along with medical and scientific journals, clinical guidelines, videos and medical blogs are important sources of real-time information for physicians and also, their patients. The application lets physicians optimize the time spent finding information. Physicians with existing journal subscriptions should not have to use dispersed channels to find published research. They would be able to access and search those journals efficiently through one centralized application, saving time. The application should also provide physicians with trending and important developments based on their search history and profile. In addition, physicians would be able to easily share and receive relevant material with their colleagues and patients. “The application can cut through the noise of the abundantly available medical information while maintaining diversity of sources.” MedNexus Whitepaper: Physicians and Information Overload 7 VIDEOSCLINICAL GUIDELINES MEDICAL/ SCIENTIFIC JOURNALS BLOGS ONE PLATFORM
MedNexus is the solution. MedNexus is a semantic search engine for Healthcare professionals and patients - think "Google for Medi- cine". We are the first to leverage machine learning and crowdsourcing to deliver relevant content based on the user’s interests. Our ranking system is based on novel machine learning algorithms that vet the clini- cal impact and relevance of published research using a variety of metrics. Search results are dynamically updated based on crowdsourced data from other similar users. The platform allows physicians to look up articles, reviews, guidelines and other high quality medical content on specific topics at point-of-care and get quick answers based on the latest medical research. It will enhance their knowledge of standards of care and new advances in their field of specialty, which will translate into better care delivery. Our tool serves not only as a clinical reference for practicing physi- cians and medical students, but will also act as an educational resource for health consumers who want to gather information on a topic they don’t know much about.
