Real-Time Electronic Patient Portal Use Among Emergency Department Patients

Importance

Patients with inequitable access to patient portals frequently present to emergency departments (EDs) for care. Little is known about portal use patterns among ED patients.

Objectives

To describe real-time patient portal usage trends among ED patients and compare demographic and clinical characteristics between portal users and nonusers.

Design, Setting, and Participants

In this cross-sectional study of 12 teaching and 24 academic-affiliated EDs from 8 health systems in California, Connecticut, Massachusetts, Ohio, Tennessee, Texas, and Washington, patient portal access and usage data were evaluated for all ED patients 18 years or older between April 5, 2021, and April 4, 2022.

Exposure

Use of the patient portal during ED visit.

Main Outcomes and Measures

The primary outcomes were the weekly proportions of ED patients who logged into the portal, viewed test results, and viewed clinical notes in real time. Pooled random-effects models were used to evaluate temporal trends and demographic and clinical characteristics associated with real-time portal use.

Results

The study included 1 280 924 unique patient encounters (53.5% female; 0.6% American Indian or Alaska Native, 3.7% Asian, 18.0% Black, 10.7% Hispanic, 0.4% Native Hawaiian or Pacific Islander, 66.5% White, 10.0% other race, and 4.0% with missing race or ethnicity; 91.2% English-speaking patients; mean [SD] age, 51.9 [19.2] years). During the study, 17.4% of patients logged into the portal while in the ED, whereas 14.1% viewed test results and 2.5% viewed clinical notes. The odds of accessing the portal (odds ratio [OR], 1.36; 95% CI, 1.19-1.56), viewing test results (OR, 1.63; 95% CI, 1.30-2.04), and viewing clinical notes (OR, 1.60; 95% CI, 1.19-2.15) were higher at the end of the study vs the beginning. Patients with active portal accounts at ED arrival had a higher odds of logging into the portal (OR, 17.73; 95% CI, 9.37-33.56), viewing test results (OR, 18.50; 95% CI, 9.62-35.57), and viewing clinical notes (OR, 18.40; 95% CI, 10.31-32.86). Patients who were male, Black, or without commercial insurance had lower odds of logging into the portal, viewing results, and viewing clinical notes.

Conclusions and Relevance

These findings suggest that real-time patient portal use during ED encounters has increased over time, but disparities exist in portal access that mirror trends in portal usage more generally. Given emergency medicine's role in caring for medically underserved patients, there are opportunities for EDs to enroll and train patients in using patient portals to promote engagement during and after their visits.

Atypical Presentation of Carbon Monoxide Poisoning With Aphasia

We present a patient with carbon monoxide poisoning with a single focal neurological deficit. The patient was found by emergency medical services (EMS) to be resting in his truck with a generator running nearby. On arrival, the patient was hemodynamically stable. The patient was aphasic but did not exhibit any other focal or lateralizing deficits. He was able to communicate by writing clearly and coherently on a sheet of paper. His initial carboxyhemoglobin was 29%, confirming the diagnosis of carbon monoxide poisoning. He was treated with 100% O₂ via a non-rebreather mask and regained his speech during his ED (emergency department) course. The patient was ultimately hospitalized for continued oxygen treatment and serial examinations. This case highlights the varied presenting symptoms of carbon monoxide poisoning as well as the importance of including a broad differential diagnosis while working up patients with a focal neurologic deficit.

An Uncontrollable, Aggressive Patient at a Free-Standing Emergency Department

We present the case of an aggressive male patient who was unable to be successfully sedated with conventional medications in the ED and ultimately required intubation to ensure the safety of the patient himself and the staff. After admission to the ICU, he was found to have atrophy of the frontal and bilateral lobes secondary to a traumatic brain injury (TBI) 19 years prior. Managing the patient required collaboration with the intensivist, hospitalist, and psychiatry and neurology teams for 10 months, and he was refused admission to multiple psychiatric facilities due to safety concerns because of his high level of aggression and unpredictability. An out-of-state, high-security facility eventually accepted the patient. The second challenge was finding a highly trained medical team willing to transport the patient. This case illustrates the difficulty and safety concerns with regard to managing an aggressive patient with previous TBI when the commonly used medications do not produce the desired effect. A literature search did not reveal a standard protocol or consensus on managing these types of patients in emergent situations.

A Model Curriculum for an Emergency Medicine Residency Rotation in Clinical Informatics

Audience

This curriculum is designed for emergency medicine residents at all levels of training. The curriculum covers basic foundations in clinical informatics for improving patient care and outcomes, utilizing data, and leading improvements in emergency medicine.

Length of Curriculum

The curriculum is designed for a four-week rotation.

Introduction

The American College of Graduate Medical Education (ACGME) mandated that all Emergency Medicine (EM) residents receive specific training in the use of information technology.1,2 To our knowledge, a clinical informatics curriculum for EM residents does not exist. We propose the following standardized and reproducible educational curriculum for EM residents.

Educational Goals

The aim of this curriculum is to teach informatics skills to emergency physicians to improve patient care and outcomes, utilize data, and develop projects to lead change.3 These goals will be achieved by providing a foundational informatics elective for EM residents that follows the delineation of practice for Clinical Informatics outlined by the American Medical Informatics Association (AMIA) and the American Board of Preventive Medicine (ABPM).4-6.

Educational Methods

The educational strategies used in this curriculum include asynchronous learning via books, papers, videos, and websites. Residents attend administrative sessions (meetings), develop a project proposal, and participate in small group discussions.The rotation emphasizes the basic concepts surrounding clinical informatics with an emphasis on improving care delivery and outcomes, information systems, data governance and analytics, as well as leadership and professionalism. The course focuses on the practical application of these concepts, including implementation, clinical decision support, workflow analysis, privacy and security, information technology across the patient care continuum, health information exchange, data analytics, and leading change through stakeholder engagement.

Research Methods

An initial version of the curriculum was introduced to two separate institutions and was completed by three rotating resident physicians and one rotating resident pharmacist. A brief course evaluation as well as qualitative feedback was solicited from elective participants by the course director, via email following the completion of the course, regarding the effectiveness of the course content. Learner feedback was used to influence the development of this complete curriculum.

Results

The curriculum was graded by learners on a 5-point Likert scale (1=strongly disagree, 5 = strongly agree). The mean response to, "This course was a valuable use of my elective time," was 5 (sd=0). The mean response to, "I achieved the learning objectives," and "This rotation helped me understand Clinical Informatics," were both 4.75 (sd=0.5).

Discussion

Overall, participants reported that the content was effective for achieving the learning objectives. During initial implementation, we found that the preliminary asynchronous learning component worked less effectively than we anticipated due to a lower volume of content. In response to this, as well as resident feedback, we added significantly more educational content.In conclusion, this model curriculum provides a structured process for an informatics rotation for the emergency medicine resident that utilizes the core competencies established by the governing bodies of the clinical informatics specialty and ACGME.

Topics

Clinical informatics key concepts, including definitions, fundamental terminology, history, policy and regulations, ethical considerations, clinical decision support, health information systems, data governance and analytics, process improvement, stakeholder engagement and change management.

Atypical Presentation of Boerhaave Syndrome With Hypoxia and Unresponsiveness

The following case discusses the atypical presentation of a spontaneous esophageal rupture that presented as acute hypoxic respiratory failure in the emergency department. The patient initially arrived by ambulance with a chief complaint of non-radiating chest pain for approximately one hour. Within minutes after arrival, the patient became hypoxic and bradycardic, requiring supplemental oxygen. A computed tomography (CT) angiogram of the chest showed a pneumothorax, pneumomediastinum, and left lower lobe consolidations concerning for pneumonia. The patient was resuscitated in the emergency department, and a chest tube thoracostomy was performed. Upon admission to the hospital, an esophagogram with contrast showed an esophageal leak at the gastroesophageal junction with the contrast extending into the left pleural space which required surgical intervention. This case highlights the complicated nature and variable presentations of Boerhaave syndrome and the importance of stabilizing the airway, breathing, and circulation in a decompensating patient even when the etiology is not clear at the time of presentation.

Acute Cauda Equina Syndrome Caused by Epidural Steroid Injection in the Setting of a Spinal Dural Arteriovenous Fistula

We present a case of acute cauda equina syndrome caused by an epidural steroid injection in the setting of a previously undiagnosed spinal dural arteriovenous fistula (SDAVF). Our patient was a 61-year-old man who presented to the emergency department with low back pain, inability to walk, paresthesias of his bilateral lower extremities, bowel and bladder incontinence, and saddle anesthesia. Physical examination revealed weakness and decreased sensation of the lower extremities as well as poor rectal tone and urinary retention. Magnetic resonance imaging (MRI) revealed evidence of spinal cord edema in the T9-10 region and a probable SDAVF with secondary distal thoracic cord ischemia. This case highlights the importance of prompt recognition of cauda equina syndrome in the emergency department, expedient imaging, and efficient transfers of care, which allowed this patient to quickly undergo necessary surgery that led to an almost complete recovery. It also highlights the importance of recognizing subtle changes on lumbar MRI.

A Case Report on Gastric Remnant Intussusception

We present a case of intussusception of a gastric remnant in a patient years after undergoing a Billroth II procedure that was treated with esophagogastroduodenoscopy. Although rare in adults, intussusception has been documented with increasing frequency in adult patients who have undergone Billroth II, mini-gastric bypass, and Roux-en-Y gastric bypass surgery. Timely management can decrease damage due to ischemia.

Consensus Development of a Modern Ontology of Emergency Department Presenting Problems-The Hierarchical Presenting Problem Ontology (HaPPy)

OBJECTIVE

Numerous attempts have been made to create a standardized "presenting problem" or "chief complaint" list to characterize the nature of an emergency department visit. Previous attempts have failed to gain widespread adoption as they were not freely shareable or did not contain the right level of specificity, structure, and clinical relevance to gain acceptance by the larger emergency medicine community. Using real-world data, we constructed a presenting problem list that addresses these challenges.

MATERIALS AND METHODS

We prospectively captured the presenting problems for 180,424 consecutive emergency department patient visits at an urban, academic, Level I trauma center in the Boston metro area. No patients were excluded. We used a consensus process to iteratively derive our system using real-world data. We used the first 70% of consecutive visits to derive our ontology, followed by a 6-month washout period, and the remaining 30% for validation. All concepts were mapped to Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT).

RESULTS

Our system consists of a polyhierarchical ontology containing 692 unique concepts, 2,118 synonyms, and 30,613 nonvisible descriptions to correct misspellings and nonstandard terminology. Our ontology successfully captured structured data for 95.9% of visits in our validation data set.

DISCUSSION AND CONCLUSION

We present the HierArchical Presenting Problem ontologY (HaPPy). This ontology was empirically derived and then iteratively validated by an expert consensus panel. HaPPy contains 692 presenting problem concepts, each concept being mapped to SNOMED CT. This freely sharable ontology can help to facilitate presenting problem-based quality metrics, research, and patient care.

Health Information Exchange in Emergency Medicine

Emergency physicians often must make critical, time-sensitive decisions with a paucity of information with the realization that additional unavailable health information may exist. Health information exchange enables clinician access to patient health information from multiple sources across the spectrum of care. This can provide a more complete longitudinal record, which more accurately reflects the way most patients obtain care: across multiple providers and provider organizations. This information article explores various aspects of health information exchange that are relevant to emergency medicine and offers guidance to emergency physicians and to organized medicine for the use and promotion of this emerging technology. This article makes 5 primary emergency medicine-focused recommendations, as well as 7 additional secondary generalized recommendations, to health information exchanges, policymakers, and professional groups, which are crafted to facilitate health information exchange's purpose and demonstrate its value.

Delphi consensus on the feasibility of translating the ACEP clinical policies into computerized clinical decision support

Clinical practice guidelines are developed to reduce variations in clinical practice, with the goal of improving health care quality and cost. However, evidence-based practice guidelines face barriers to dissemination, implementation, usability, integration into practice, and use. The American College of Emergency Physicians (ACEP) clinical policies have been shown to be safe and effective and are even cited by other specialties. In spite of the benefits of the ACEP clinical policies, implementation of these clinical practice guidelines into physician practice continues to be a challenge. Translation of the ACEP clinical policies into real-time computerized clinical decision support systems could help address these barriers and improve clinician decision making at the point of care. The investigators convened an emergency medicine informatics expert panel and used a Delphi consensus process to assess the feasibility of translating the current ACEP clinical policies into clinical decision support content. This resulting consensus document will serve to identify limitations to implementation of the existing ACEP Clinical Policies so that future clinical practice guideline development will consider implementation into clinical decision support at all stages of guideline development.

International emergency medicine: a review of the literature from 2006

The field of international emergency medicine (IEM) has grown rapidly over the past several decades, with a rise in the number of IEM fellowship positions, sustained growth in the international sections of major emergency medicine organizations, and an increase in the range of topics included under its rubric. One of the greatest obstacles to the continued growth of IEM remains the lack of a high-quality, consolidated, and easily accessible evidence base of literature. In response to this perceived need, members of the Emergency Medicine Residents' Association IEM Committee, in conjunction with members of the Society for Academic Emergency Medicine International Health Interest Group, embarked on the task of creating a recurring review of IEM literature. This article reviews 25 IEM research articles published in 2006. Research articles were selected for the review according to explicit, predetermined criteria that included both methodological quality and perceived impact of the research. It is the authors' hope that this annual review will act as a forum for disseminating best practices while also stimulating further research in the field of IEM.

Internet-based standardized patient simulation with automated feedback

There exist many modalities for teaching and testing medical students. One method being explored is computer-based patient simulation. Traditionally, exposure to a variety of patients has been achieved through years of training under the supervision of experts in the field. Computerized patient simulation has been proposed as a method of creating a standardized patient care experience through algorithms and predefined patient findings. One study reported that after experience with computer-based simulation, 80% of students and mentors felt that it should be a mandatory part of medical education. Access to effective simulations with high-yield cases can be costly. Internet-based tools enjoy easy distribution and centralized maintenance. Simulations distributed via the Internet have proven successful in selected medical fields. Automated scoring of patient interactions has also been proposed as a way to eliminate the effort required for mentor evaluation.
