AbstractThis article presents an overview of a research project concerning the consultation of medical narratives in the electronic medical record (EMR). It describes an analysis of user needs, the design and implementation of a prototype EMR system, and the evaluation of the ease of consultation of medical narratives when using this system. In a questionnaire survey, 85 hospital physicians judged the quality of their paper-based medical record with respect to data entry, information retrieval and some other aspects. Participants were more positive about the paper medical record than the literature suggests. They wished to maintain the flexibility of data entry but indicated the need to improve the retrieval of information. A prototype EMR system was developed to facilitate the consultation of medical narratives. These parts were divided into labeled segments that could be arranged source-oriented and problem-oriented. This system was used to evaluate the ease of information retrieval of 24 internists and 12 residents at a teaching hospital when using free-text medical narratives divided at different levels of detail. They solved, without time pressure, some predefined problems concerning three voluminous, inpatient case records. The participants were randomly allocated to a sequence that was balanced by patient case and learning effect. The division of medical narratives affected speed, but not completeness of information retrieval. Progress notes divided into problem-related segments could be consulted 22% faster than when undivided. Medical history and physical examination divided into segments at organ-system level could be consulted 13% faster than when divided into separate questions and observations. These differences were statistically significant. The fastest divisions were also appreciated as the best combination of easy searching and best insight in the patient case. The results of our evaluation study suggest a trade-off between searching and reading: too much detailed segments will delay the consultation of medical narratives. Validation of the results in daily practice is recommended.

Abstract Objectives Given the importance of onboarding education in ensuring the safety and efficiency of medical users in the electronic medical record (EMR), we re-designed our EMR curriculum to incorporate adult learning principles, informed and delivered by peers. We aimed to evaluate the impact of these changes based on their satisfaction with the training. Methods A single site pre- and post-observational study measured satisfaction scores (four questions) from junior doctors attending EMR onboarding education in 2018 (pre-implementation) compared with 2019 (post-implementation). An additional four questions were asked in the post-implementation survey. All questions employed a Likert scale (1–5) with an opportunity for free-text. Raw data were used to calculate averages, standard deviations and the student t-test was used to compare the two cohorts where applicable. Results There were a total of 98 respondents in 2018 (pre-implementation) and 119 in 2019 (post-implementation). Satisfaction increased from 3.8/5 to 4.5/5 (p < 0.0001) following implementation of a peer-delivered curriculum in line with adult learning practices. The highest-rated factors were being taught by other doctors (4.9/5) and doctors having the appropriate knowledge to deliver training (4.9/5). Ninety-two percent of junior doctors were motivated to engage in further EMR education and 90% felt classroom support was adequate. Conclusion EMR onboarding education for medical users is a critical ingredient to organizational safety and efficiency. An improvement in satisfaction ratings by junior doctors was demonstrated after significant re-design of the curriculum was informed and delivered by peers, in line with adult learning principles.

The controlled vocabulary versus the free text approach to information retrieval is reviewed from the mid 1960s to the early 1980s. The dominance of the free text approach following the Cranfield tests is increasingly coming into question as a result of tests on existing online data bases and case studies. This is supported by two case studies on the Coffeeline data base. The differences and values of the two approaches are explored considering thesauri as semantic maps. It is suggested that the most appropriate evaluatory technique for indexing languages is to study the actual use made of various techniques in a wide variety of search environments. Such research is becoming more urgent. Economic and other reasons for the scarcity of online thesauri are reviewed and suggestions are made for methods to secure revenue from thesaurus display facilities. Finally, the promising outlook for renewed develop ment of controlled vocabularies with more effective online display techniques is mentioned, although such development must be based on firm research of user behaviour and needs.

Background and Purpose The literature demonstrates how utilizing evidence-based, standardized stroke care can improve patient outcomes; however, the contribution of electronic medical record (EMR) systems may also impact outcomes by ensuring utilization and compliance with established stroke performance measures, facilitating and improving documentation requirements, and standardizing approach to care. In 2008, documentation in patients’ medical records was done in combination of paper and a template free EMR. Originally, the EMR was used for order entry, then transitioned to full electronic documentation in 2009. At that time we implemented our stroke templates and performance measures based on regulatory standards. We hypothesized that the stroke template implementation would help us achieve performance measure criteria above state benchmarks as set out by the New York State Department of Health (NYS DOH). Methods Implementation was phased in [over 18 months], initially using a template that only included neurological assessment and free text fields for stroke measures. By July 2010, existing templates were modified and additional stroke templates were implemented to meet new regulatory requirements and meaningful use criteria. Retrospective data review was conducted for performance comparison between 2008 -- one year prior to EMR/template implementation -- and 2010. In Quarter 1 of 2011 EMR was also implemented in the Emergency Department (ED). Data was reviewed for compliance with stroke measures. Results Documentation compliance substantially improved between 2008 and Quarter 1 2011: Compliance for these measures has been maintained ≥ 85% since November 2010, ≥ 90% Q1 2011 Conclusions The EMR implementation of stroke templates and performance measures can produce substantial improvement in performance measure compliance. Future steps will include automated documentation alerts to retrieve information and real time discovery of missing documentation for concurrent quality review and improvement

The present form of the medical record evolved when patient care was primarily a single physiciansingle patient relationship. However, in recent decades, there have been radical changes in the needs and patterns of health care delivery, and this scrap-book format for a medical record is grossly deficient.The largest portion of the medical record consists of narrative or free text which is hand-written in relatively unstructured, and often illegible, prose. Although the computer can be used for medical record processing by the unmodified entry of data in prose form, there are very critical limitations in such applications. A more challenging approach is to collect the information in an interactive, conversational technique between the user and the computer, where there is a predetermined branching structure of the data and a fixed vocabulary. The information is entered by the user selecting the desired items from a list on a display screen. The presentation of the particular display by the computer is determined by all the previous choices made by the user. This style of collecting information not only insures clear and unambiguous data, but also facilitates continuing medical education, medical audit, and clinical investigation.

The Facilitated Access File, described herein, has proved to be an acceptable, relatively simple, yet feasible strategy for general medical record information retrieval at a university hospital clinic. Physicians record physical examination data in free-text mode, then through a rapid exercise of judgment, create an index to these data which is computer-stored. Such an index file provides future investigators facilitated access back to the original handwritten data and permits a variety of statistical studies. The system has been in use for over a year and has proved to be of value in clinical research and student teaching.

In this paper the existing functions of, and a number of future requirements for, information retrieval systems are dis cussed. Two basic requirements for free text information retri eval systems have been identified; one for a more general information modelling language and the other for a simple user interface for complex ad-hoc queries. The paper describes some existing and proposed hardware and software methods for implementing free text information retrieval systems. Emphasis is placed on methods of improving the functionality of the system rather than on methods of increasing the performance. It is suggested that considerable improvements can be achieved by a more imaginative use of existing hardware, though it is realised that special purpose architectures will play an increas ingly important role in information systems. The paper con cludes with a design for a new information retrieval system based on the use of the Binary Relationship Model for infor mation storage and retrieval, and an interactive graphical dis play for the user interface.

BACKGROUND Since the creation of the Problem Oriented Medical Record, the building of problem lists has been the focus of many researches. To this day, this issue is not well resolved, and building an appropriate contextualized problem list is still a challenge. OBJECTIVE This paper presents the process of building a shared multi-purpose common problem list at the University Hospitals of Geneva, a consortium of all public hospitals and 30 outpatient clinics of the state of Geneva. This list aims at bridging the gap between clinicians’ language expressed in free text and secondary usages requiring structured information. METHODS The strategy focuses on the needs of clinicians by building a list of uniquely identified expressions to support their daily activities. In a second stage, these expressions are connected to additional information, building a complex graph of information. A list of 45,946 expressions manually extracted from clinical documents has been manually curated and encoded in multiple semantic dimensions, such as ICD-10, ICPC-2, SNOMED-CT or dimensions dictated by specific usages, such as identifying expressions specific to a domain, a gender, or an intervention. The list has been progressively deployed for clinicians with an iterative process of quality control, maintenance and improvements, including addition of new expressions, or dimensions for specific needs. The problem management of the electronic health record allowed to measure and correct the encoding based on real-world usage. RESULTS The list was deployed in production in January 2017 and was regularly updated and deployed in new divisions of the hospital. In 4 years, 684,102 problems were created using the list. The proportion of free text entries reduced progressively from 37.47% (8,321/22,206) in December 2017 to 18.38% (4,547/24,738) in December 2020. In the last version of the list, over 14 dimensions were mapped to expressions, among them 5 international classifications and 8 other classifications for specific usages. The list became a central axis in the EHR, being used for many different purposes linked to care such as surgical planning or emergency wards, or in research, for various predictions using machine learning techniques. CONCLUSIONS This work breaks with common approaches primarily by focusing on real clinicians’ language when expressing patient’s problems and secondly by mapping whatever is required, including controlled vocabularies to answer specific needs. This approach improves the quality of the expression of patients’ problems, while allowing to build as many structured dimensions as needed to convey semantics according to specific contexts. The method is shown to be scalable, sustainable and efficient at hiding the complexity of semantics or the burden of constraint structured problem list entry for clinicians. Ongoing work is analyzing the impact of this approach at influencing how clinicians express patient’s problems.

This study presents an intelligent information retrieval system that will effectively extract useful information from breast cancer datasets and utilized that information to build a classification model. The proposed model will reduce the missed cancer rate by providing a comprehensive decision support to the radiologist. The model is built on two datasets, Wisconsin Breast Cancer Dataset (WBCD) and 365 free text mammography reports from a hospital. Effective pre-processing techniques including filling missing values with regression, an effective Natural Language Processing (NLP) Parser is developed to handle free text mammography reports, balancing the dataset with Synthetic Minority Oversampling (SMOTE) was applied to prepare the dataset for learning. Most relevant features were selected with the help of filter method and tf-idf scores. K-NN and SGD classifiers are optimized with optimum value of k for K-NN and hyper tuning the SGD parameters with grid search technique.
