Developing Data Model for Electronic Health Record System

IntroductionThe ability to utilize the electronic health record (EHR) without compromising the doctor-patient relationship (DPR) is an essential skill of all physicians and trainees, yet little time is spent on educating or assessing learners on needed techniques. To address this gap, we developed a conventional OSCE station coupled with a simulated patient chart within the Epic program in order to assess our students' skills utilizing the EHR during a patient encounter.MethodsOf third-year medical students, 119 were given full access to the patient's simulated chart 24 hours in advance of their OSCE to review clinical data. During an in-person OSCE with a standardized patient (SP), students performed a focused history and physical, using the EHR to verify allergies and medications. Students completed an electronic patient note graded by faculty. SPs evaluated the students on communication and interpersonal skills with specific rubric elements. Faculty graded the students' notes to evaluate their expression of clinical reasoning in the assessment and plan.ResultsTraining SPs and faculty to assess students on EHR skills was feasible. After implementation of a comprehensive curriculum focused on EHR and DPR, there was a significant difference on EHR-related communication skills (M = 76.4, SD = 17.6) versus (M = 37, SD = 28.9) before curriculum enhancement t (117.9) = −12.4, p <.001.DiscussionThe EHR OSCE station provided a standardized method of assessing students' EHR skills during a patient encounter. Challenges still exist in the technological requirements to develop and deliver cases in today's EHR platform.

BackgroundClinicians’ use of electronic health record (EHR) systems while multitasking may increase the risk of making errors, but silent EHR system use may lower patient satisfaction. Delaying EHR system use until after patient visits may increase clinicians’ EHR workload, stress, and burnout.ObjectiveWe aimed to describe the perspectives of clinicians, educators, administrators, and researchers about misses and near misses that they felt were related to clinician multitasking while using EHR systems.MethodsThis observational study was a thematic analysis of perspectives elicited from 63 continuing medical education (CME) participants during 2 workshops and 1 interactive lecture about challenges and strategies for relationship-centered communication during clinician EHR system use. The workshop elicited reflection about memorable times when multitasking EHR use was associated with “misses” (errors that were not caught at the time) or “near misses” (mistakes that were caught before leading to errors). We conducted qualitative analysis using an editing analysis style to identify codes and then select representative themes and quotes.ResultsAll workshop participants shared stories of misses or near misses in EHR system ordering and documentation or patient-clinician communication, wondering about “misses we don’t even know about.” Risk factors included the computer’s position, EHR system usability, note content and style, information overload, problematic workflows, systems issues, and provider and patient communication behaviors and expectations. Strategies to reduce multitasking EHR system misses included clinician transparency when needing silent EHR system use (eg, for prescribing), narrating EHR system use, patient activation during EHR system use, adapting visit organization and workflow, improving EHR system design, and improving team support and systems.ConclusionsCME participants shared numerous stories of errors and near misses in EHR tasks and communication that they felt related to EHR multitasking. However, they brainstormed diverse strategies for using EHR systems safely while preserving patient relationships.

Usability problems do not heal by themselves: National survey on physicians’ experiences with EHRs in Finland

IntroductionAccurate identification of Aged Care residents accessing hospital services is challenging due to multiple hospital Electronic Health Record (EHR) systems and entry points resulting in inconsistent addresses and coding. Improving accuracy and completeness of addresses is crucial for cohort identification and data linkage. ObjectiveDevelop methods to validate cross-sectoral data linkages to improve identification of aged care residents within EHR systems. ApproachAmong individuals aged ≥65 years (or ≥50 identifying as Aboriginal or Torres Strait Islander) between January 2013 to December 2023 within our Data Platform, we first used data items mandated by the Department of Health to identify aged care residency. Data quality was enhanced using a residential address index derived from Australian Geocoded National Address File (G-NAF). We evaluated sensitivity, specificity, and Positive Predictive Values (PPVs) of recorded addresses against the Australian Institute of Health and Welfare (AIHW) aged care services list. ResultsAmong 409,677 addresses extracted, 55.4% (raw) had sufficient data for validation. This increased to 89.9% (enhanced) with G-NAF. Among 79,028 admitted and 88,876 emergency patients, 22.7% and 18.4% respectively were aged care residents. We compared performance of raw vs enhanced comparisons were: sensitivity (admission: 34.1% vs 73.8%), (emergency: 42.6% vs 66.2%); specificity (admission: 96.2% vs 90.9%), emergency (96.8% vs 95.2%); Positive Predictive Value (admission: 61.3% vs 58.8%), (emergency: 64.2% vs 65.3%). Conclusions and ImplicationsOur approach significantly increased sensitivity without sacrificing specificity, enhancing Aged Care resident identification in EHR data. It also improved linkage with external datasets and Statistical Area Level 1 (SA1) mapping.

This paper presents the impact of the Electronic Health Records (EHRs) systems jointly in the Spanish Primary Public Health System. Different EHRs that exist in each of the Spanish regions are discussed. Moreover, other purpose of this analysis is to identify the current state of knowledge about health information systems adoption in primary care in Spain. For the analysis and study of EHRs systems in Spain we have relied on the use of different sources, mostly items related to the study of EHRs systems in different areas. We will analyze some technical aspects of these and some of their major implications, both positive and negative. Moreover, we have resorted to make direct contact with the organizations that have implemented the EHRs systems. The result of this study leads to a main idea, the need for interoperability between different systems. We will delve into how we have reached this conclusion and that is the key to EHRs systems homogenization of Spanish territory. EHR systems used in different regions of Spain offer the access to medical information as well as provide a clinical analysis of each patient more quickly. The adoption of health information systems is seen world wide as one method to mitigate the widening health care demand and supply gap.

The geo-spatial database is a new technology in database systems which allow storing, retrieving and maintaining the spatial data.In this paper, we seek to design and implement a geo-spatial database for managing the traveler's demand with the aid of open-source tools and object-relational database package.The building of geo-spatial database starts with the design of data model in terms of conceptual, logical and physical data model and then the design has been implemented into an object-relational database.The geo-spatial database is developed to facilitate the storage of geographic information (where things are) with descriptive information (what things are like) into the vector model.The developed vector geo-spatial data can be accessed and rendered in the form of map to create the awareness of existence of various services and facilities for prospective travelers and visitors.

BackgroundThe natural language processing (NLP) algorithm for predetermined asthma criteria (NLP-PAC) was successfully developed and validated for automatically ascertaining pediatric asthma from electronic health record (EHRs) systems. A scalable, efficient, and automated tool for ascertaining adult asthma status from EHRs remains nonexistent.ObjectiveWe validated NLP-PAC enabling ascertainment and early identification of adult asthma status in their EHRs.MethodsWe applied the validated NLP-PAC to EHRs of a convenient sample (adult cohorts who participated in our previous population-based studies) in which a reference standard (ie, asthma status defined by manual chart review) is available. The performance of NLP-PAC was assessed by determining criterion validity against manual chart review and construct validity before and after the new EHR (Epic) system was implemented in 2018.ResultsThe cohort consisted of 1,898 subjects, with 43% male and a median age at time of last follow-up of 65 years (interquartile range, 55-76). Manual chart review and NLP-PAC identified 97 (5.1%) and 98 (5.1%) subjects with asthma, respectively, with 89 subjects commonly identified by both methods. The sensitivity, specificity, positive predictive value, and negative predictive value of NLP-PAC were 92%, 99%, 91%, and 99%, respectively, before the new EHR system was implement, which remained similar after introducing the system (95%, 88%, 96%, and 85%, respectively). The risk factors for asthma identified either by NLP-PAC or manual chart review were similar.ConclusionAutomatic asthma ascertainment for adults based on EHR data is feasible with our NLP algorithm, offering immense scientific and clinical value for large-scale clinical research and population management for adult asthma care.

Nurses are one of the largest user groups of the electronic health record (EHR) system, relying on its tools to support patient care and nursing workflows. Recent studies suggested that the redesign of nursing documentation may reduce the time spent in the EHR system and improve nurse satisfaction. We aimed to assess nurses' perceptions of the redesigned EHR, evaluate the impact of documentation interventions, and identify future improvement needs. Guided by the American Nursing Informatics Association's Six Domains of Burden conceptual framework, this multimethod project combined both qualitative and quantitative approaches. Registered nurses across the academic health system were recruited via email invitations to participate in focus group discussions. The focus groups were conducted via a web conference and ranged from 60 to 90 minutes in duration. The focus group discussions were transcribed and analyzed through thematic analysis. The EHR vendor's time data were used to analyze nurses' time spent in documentation. In total, 20 registered nurses participated in the focus group discussions, and 17 nurses completed the demographic survey; 88% (15/17) of participants had ≥3 years of EHR experience at the academic health system, and 53% (9/17) self-reported being competent in the EHR system. The following six themes emerged: positive feedback, usability and workflow opportunities, nuisance, training and education, communication, and time spent in the system. EHR vendor time data revealed that the time spent in flowsheets averaged 31.11% per 12-hour shift. Overall, participants reported a positive experience and that the EHR supported patient care. There are opportunities to further reduce redundancies in documentation and implement programs that support continuous learning about EHR and health technology tools. Specific suggestions include optimizing the oral health assessment tool. Analyzing frontline nursing perspectives in the redesign of EHR workflows is imperative for identifying interventions that support nurses' satisfaction with the EHR.

BackgroundThe implementation of Electronic Health Record (EHR) systems is a critical challenge, particularly in low-income countries, where behavioral intention plays a crucial role. To address this issue, we conducted a study to extend and apply the Unified Theory of Acceptance and Use of Technology 3 (UTAUT3) model in predicting health professionals' behavioral intention to use EHR systems.MethodsA quantitative research approach was employed among 423 health professionals in Southwest Ethiopia. We assessed the validity of the proposed model through measurement and structural model statistics. Analysis was done using SPSS AMOS version 23. Hypotheses were tested using structural equation modeling (SEM) analysis, and mediation and moderation effects were evaluated. The associations between exogenous and endogenous variables were examined using standardized regression coefficients (β), 95% confidence intervals, and p-values, with a significance level of p-value < 0.05.ResultsThe proposed model outperformed previous UTAUT models, explaining 84.5% (squared multiple correlations (R2) = 0.845) of the variance in behavioral intention to use EHR systems. Personal innovativeness (β = 0.215, p-value < 0.018), performance expectancy (β = 0.245, p-value < 0.001), and attitude (β = 0.611, p-value < 0.001) showed significant associations to use EHR systems. Mediation analysis revealed that performance expectancy, hedonic motivation, and technology anxiety had significant indirect effects on behavioral intention. Furthermore, moderation analysis indicated that gender moderated the association between social influence, personal innovativeness, and behavioral intention.ConclusionThe extended UTAUT3 model accurately predicts health professionals' intention to use EHR systems and provides a valuable framework for understanding technology acceptance in healthcare. We recommend that digital health implementers and concerned bodies consider the comprehensive range of direct, indirect, and moderating effects. By addressing personal innovativeness, performance expectancy, attitude, hedonic motivation, technology anxiety, and the gender-specific impact of social influence, interventions can effectively enhance behavioral intention toward EHR systems. It is crucial to design gender-specific interventions that address the differences in social influence and personal innovativeness between males and females.

BackgroundOne of the primary obstacles to the widespread adoption of openEHR methodology is the lack of practical persistence solutions for future-proof electronic health record (EHR) systems as described by the openEHR specifications. This paper presents an archetype relational mapping (ARM) persistence solution for the archetype-based EHR systems to support healthcare delivery in the clinical environment.MethodsFirst, the data requirements of the EHR systems are analysed and organized into archetype-friendly concepts. The Clinical Knowledge Manager (CKM) is queried for matching archetypes; when necessary, new archetypes are developed to reflect concepts that are not encompassed by existing archetypes. Next, a template is designed for each archetype to apply constraints related to the local EHR context. Finally, a set of rules is designed to map the archetypes to data tables and provide data persistence based on the relational database.ResultsA comparison study was conducted to investigate the differences among the conventional database of an EHR system from a tertiary Class A hospital in China, the generated ARM database, and the Node + Path database. Five data-retrieving tests were designed based on clinical workflow to retrieve exams and laboratory tests. Additionally, two patient-searching tests were designed to identify patients who satisfy certain criteria. The ARM database achieved better performance than the conventional database in three of the five data-retrieving tests, but was less efficient in the remaining two tests. The time difference of query executions conducted by the ARM database and the conventional database is less than 130 %. The ARM database was approximately 6–50 times more efficient than the conventional database in the patient-searching tests, while the Node + Path database requires far more time than the other two databases to execute both the data-retrieving and the patient-searching tests.ConclusionsThe ARM approach is capable of generating relational databases using archetypes and templates for archetype-based EHR systems, thus successfully adapting to changes in data requirements. ARM performance is similar to that of conventionally-designed EHR systems, and can be applied in a practical clinical environment. System components such as ARM can greatly facilitate the adoption of openEHR architecture within EHR systems.

Electronic Health Record (EHR) systems are the cornerstone of the healthcare industry. Looking through the combined theoretical lens of value co-creation (VCC) and the relational view, this article uses the qualitative case study methodology to get an in-depth understanding of value co-creation in EHR systems. The spirit of this study is discovery. Value co-creation perspectives of different business-unit heads within an extensive hospital system were gathered to identify: (1) the key values reciprocally co-created and recognized in a multi-unit EHR environment, and (2) critical challenges facing the implementation of EHR systems in such multi-unit environments. Based on the study results, a conceptual framework is proposed highlighting five VCC dimensions of EHR in multi-unit environments: systems & data, information, processes, relationships, and regulations.

Patients engaged in self-care through information technology can potentially improve the quality of healthcare they receive. This study aimed to examine how electronic health record (EHR) system functionalities help hospitals mediate the impact of patient engagement on quality outcomes-notably, readmission rates. A pooled cross-sectional study design employed data containing 3,547 observations from general acute care hospitals (2014-2018). The breadth of patient engagement functionalities adopted by a hospital was used as the independent variable and the degree of EHR presence was used as the mediating variable. Mean time to readmission for acute myocardial infarction (AMI), pneumonia, and heart failure were the dependent variables. The Baron and Kenny method was used to test mediation. Patient engagement was associated with reduced AMI readmission rates both directly and via EHR system presence. Mediation effects were present, in that a 1-unit increase in patient engagement through EHR system presence was associated with a 0.33% decrease in AMI readmission rates (p <.05). For other disease categories (heart failure and pneumonia), a significant effect was not found. For hospitals with a comprehensive EHR system, patient engagement through information technology can potentially reduce readmission rates for some diseases. More research is needed to determine which specific clinical conditions are amenable to quality improvement through patient engagement. Synergies between patient engagement functionalities and an EHR system positively affect quality outcomes. Therefore, practitioners and hospital managers should leverage hospital investments made in their EHR system infrastructure and use it to engage patients in self-care.

BackgroundThe increasing adoption of electronic health record (EHR) systems enables automated, large scale, and meaningful analysis of regional population health. We explored how EHR systems could inform surveillance of trauma-related emergency department visits arising from seasonal, holiday-related, and rare environmental events.MethodsWe analyzed temporal variation in diagnosis codes over 24 years of trauma visit data at the three hospitals in the University of Washington Medicine system in Seattle, Washington, USA. We identified seasons and days in which specific codes and categories of codes were statistically enriched, meaning that a significantly greater than average proportion of trauma visits included a given diagnosis code during that time period.ResultsWe confirmed known seasonal patterns in emergency department visits for trauma. As expected, cold weather-related incidents (e.g. frostbite, snowboarding injury) were enriched in the winter, whereas fair weather-related incidents (e.g. bug bites, boating accidents, bicycle accidents) were enriched in the spring and summer. Our analysis of specific days of the year found that holidays were enriched for alcohol poisoning, assaults, and firework accidents. We also detected one time regional events such as the 2001 Nisqually earthquake and the 2006 Hanukkah Eve Windstorm.ConclusionsThough EHR systems were developed to prioritize operational rather than analytic priorities and have consequent limitations for surveillance, our EHR enrichment analysis nonetheless re-identified expected temporal population health patterns. EHRs are potentially a valuable source of information to inform public health policy, both in retrospective analysis and in a surveillance capacity.

Background:The Electronic Health Record (EHR) system is a systematic collection of health information based on electronics and integrated with information systems in the hospital network. The use of the EHR system is very important in a comprehensive strategy to improve the quality of health and patient safety, especially in the operating room. Purpose: to find out the benefits of using EHR on operating room efficiency which includes treatment costs, OR efficiency metrics, turn over time, documentation time and nursing quality. Method: This literature review was searched through relevant evidence-based studies usingdatabase at PROQUEST, Science Direct, Scopus, Elsevier from 2017-2021. Results:The EHR system has a cost-saving impact on the average operating room cost of 36-37 dollars per minute and can reduce costs during pre, intra and post surgery. For the FPIR value from the data of 27,403 cases after post-implementation to 9,630 cases, it means that there are no missing patients to enter the operating room, while at the time of delay the FCOTSin pre-implementation of EHR was 1972 cases or (7.20%) and post-implementation 377 cases (3.91%). Meanwhile, the turn over time (TOT) after post implementation showed a significant increase of 53 minutes, p &lt; 0.001. The introduction of the EHR also had an impact on increasing documentation time for nurses from 23% to 35%. In addition, it also provides benefits to the quantity and quality of nursing. Conclusion: The usefulness of the EHR system contributes to increasing the efficiency of the operating room so that it can provide effectiveness in service and quality of care. Nurses are expected to be able to input the EHR system and service agencies can implement these technological developments

An Electronic Health Record (EHR) system is a computerised medical information system that collects, displays, and stores a patient’s information. It is an evidence base that addresses issues associated with patients’ paper records. Implementing such a system will have a high positive impact on healthcare quality and healthcare services. For example, an EHR is an electronic record that sequentially stores any resident’s health data from nearly the first month of gestation until death, and can bring those records anytime and to any authorised physician. The objectives of this study are to investigate the present status of EHR implementations around the world, and to identify best practice solutions. Additionally, the study focuses on how to adopt best practices in Australia. The methodology of this paper involved an academic research consisting of 250 articles and over 100 websites. All of the information in this paper was obtained through a search strategy—using PubMed, Google Scholar, and Google—of the best practices applied in many countries, including the US, Canada, and several nations in Western Europe. With 30 references used that provided the recommendations to adopt the best practice solutions for Australian My Health Record system while implementation. This paper has further exposed the problems with EHR systems as implemented worldwide. The recommendations can be summarised as follows: improve the overall awareness of the stakeholders, conduct training sessions for stakeholders on My Health Record system, reward physicians for using the system, achieve ongoing technical and systems security integrity and compliance, implement a response plan in the event of a breach of the EHR system, and implement a simple graphical user interface to facilitate access to stakeholders. Further results as recommendations are provided in the results section. The research concluded that by adopting these best practice solutions, Australia will be able to achieve a stable healthcare system, which will ensure a higher level of healthcare quality to patients and healthcare alike. This paper will give stakeholders a clear vision to determine the original cause that hinders satisfying results while implementing My Health Record system in Australia.
