Rapid deployment of virtual ICU support during the COVID-19 pandemic

Flow-Sizing Critical Care Resources

OBJECTIVES

To describe the factors affecting critical care capacity and how critical care organizations (CCOs) within academic centers in the U.S. flow-size critical care resources under normal operations, strain, and surge conditions.

DATA SOURCES

PubMed, federal agency and American Hospital Association reports, and previous CCO survey results were reviewed.

STUDY SELECTION

Studies and reports of critical care bed capacity and utilization within CCOs and in the United States were selected.

DATA EXTRACTION

The Academic Leaders in the Critical Care Medicine Task Force established regular conference calls to reach a consensus on the approach of CCOs to "flow-sizing" critical care services.

DATA SYNTHESIS

The approach of CCOs to "flow-sizing" critical care is outlined. The vertical (relation to institutional resources, e.g., space allocation, equipment, personnel redistribution) and horizontal (interdepartmental, e.g., emergency department, operating room, inpatient floors) integration of critical care delivery (ICUs, rapid response) for healthcare organizations and the methods by which CCOs flow-size critical care during normal operations, strain, and surge conditions are described. The advantages, barriers, and recommendations for the rapid and efficient scaling of critical care operations via a CCO structure are explained. Comprehensive guidance and resources for the development of "flow-sizing" capability by a CCO within a healthcare organization are provided.

CONCLUSIONS

We identified and summarized the fundamental principles affecting critical care capacity. The taskforce highlighted the advantages of the CCO governance model to achieve rapid and cost-effective "flow-sizing" of critical care services and provide recommendations and resources to facilitate this capability. The relevance of a comprehensive approach to "flow-sizing" has become particularly relevant in the wake of the latest COVID-19 pandemic. In light of the growing risks of another extreme epidemic, planning for adequate capacity to confront the next critical care crisis is urgent.

Feasibility Study of a Fully Synchronous Virtual Critical Care Elective Focused on Learner Engagement

Background: The COVID-19 pandemic disrupted clinical education for medical students. With the rise of variants, meaningful in-person clinical experiences remain threatened. This report describes the design, implementation, and evaluation of a fully synchronous virtual critical care elective for medical students focused on learner engagement.

Methods: The two-week elective was offered during June and July 2020 in the COVID-19 extracorporeal membrane oxygenation (ECMO) unit. Medical students remotely participated in multidisciplinary rounds with the attending physician connected from the bedside via a head-mounted camera providing the first-person video view. Other team members connected outside the negative pressure area. Learners electronically completed daily intensive care unit (ICU) goals sheet (GS) for each patient. The daily completion percentage of the GS assessed the learner engagement, and the learners evaluated the experience with a five-point Likert scale survey.

Results: Nine medical students participated in two separate cohorts. Cohort A had 53 patient encounters, and Cohort B had 45 patient encounters totaling 301.5 total hours of supervised virtual patient interaction. The mean completion percentage of the daily ICU GS for the combined cohorts was 77.8%, (with a standard deviation of 9.6%), with sustained or increased completion from start to finish for all learners. All medical students agreed that the daily ICU GS was helpful for following rounds, organizing patient assessments and plans, and participating in patient care. The majority (88.9%) agreed that the elective increased their comfort in caring for critically ill patients.

Conclusions: During the COVID-19 pandemic, a fully synchronous virtual critical care elective successfully utilized the first-person view and daily ICU GS to promote and assess learner engagement.

Telemedicine Intensive Care Unit (Tele-ICU) Implementation During COVID-19: A Scoping Review

Telemedicine intensive care unit (Tele-ICU) programs entail command centers staffed with intensivists and critical care nurses who electronically aid with and deliver real-time information to frontline clinicians. The benefits of Tele-ICU are numerous, but the barriers to it often prove insurmountable, accounting for slow adoption in rural and underserved areas where it is needed the most. Remote monitoring can quickly detect patient deterioration, while consultation provided by a remote intensivist expands the capabilities of smaller facilities. The emergence of the coronavirus disease 2019 (COVID-19) pandemic has brought about a sense of urgency, paving the way for the successful adaptation of tele-intensive care concepts. The goal of this scoping review is to map out the available published data regarding healthcare professionals’ experiences with implementing Tele-ICU modalities during the COVID-19 pandemic. A primary literature search was performed on PubMed/MEDLINE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases from October 2020 to October 2021. Of the 1,083 records screened, 19 were identified as meeting our inclusion criteria and selected for the final scoping review. Five major areas of Tele-ICU use were identified: teleconsultation, telerounding, telemonitoring, family visitation via teleconference, and changing of hospital infrastructure. A heterogeneous mix of improvised Tele-ICU platforms emerged with a common theme of interdisciplinary and family collaboration in the care of critically ill patients. Existing Tele-ICU systems were expanded, and novel programs were launched. A groundbreaking national network in the U.S. (NETCCN) will standardize the deployment of Tele-ICU and expand its reach. Future research should focus on determining accurate costs and the most reliable forms of remote communication, physician compact agreement licensure, the practical composition of Tele-ICU teams, and standardized access to the electronic health record.

Developing an Innovative System of Open and Flexible, Patient-Family-Centered, Virtual Visiting in ICU During the COVID-19 Pandemic: A Collaboration of Staff, Patients, Families, and Technology Companies

Few challenges of the COVID-19 pandemic strike at the very core of our humanity as the inability of family to sit at the bedside of their loved ones when battling for their lives in the ICU. Virtual visiting is one tool to help deal with this challenge. When introducing virtual visiting into our ICU, we identified 5 criteria for a sustainable system that aligned with patient-family-centered care: virtual visiting needed to (1) simulate open and flexible visiting; (2) be able to accommodate differences in family size, dynamics, and cultural practices; (3) utilize a video conferencing platform that is private and secure; (4) be easy to use and not require special teams to facilitate meetings; and (5) not increase the workload of ICU staff. There is a growing body of literature demonstrating a global movement toward virtual visiting in ICU, however there are no publications that describe a system which meet all 5 of our criteria. Importantly, there are no papers describing systems of virtual visiting which mimic open and flexible family presence at the bedside. We were unable to find any off-the-shelf video conferencing platforms that met all our criteria. To come up with a solution, a multidisciplinary team of ICU staff partnered with healthcare technology adoption consultants and two technology companies to develop an innovative system called HowRU. HowRU uses the video conferencing platform Webex with the integration of some newly designed software that automates many of the laborious and complex processes. HowRU is a cloud based, supported, and simplified system that closely simulates open and flexible visiting while ensuring patient and family privacy, dignity, and security. We have demonstrated the transferability of HowRU by implanting it into a second ICU. HowRU is now commercially available internationally. We hope HowRU will improve patient-family-centered care in ICU.

Inpatient Telemedicine and New Models of Care during COVID-19: Hospital Design Strategies to Enhance Patient and Staff Safety

The challenges of the COVID-19 pandemic have led to the development of new hospital design strategies and models of care. To enhance staff safety while preserving patient safety and quality of care, hospitals have created a new model of remote inpatient care using telemedicine technologies. The design of the COVID-19 units divided the space into contaminated and clean zones and integrated a control room with audio-visual technologies to remotely supervise, communicate, and support the care being provided in the contaminated zone. The research is based on semi-structured interviews and observations of care processes that implemented a new model of inpatient telemedicine at Sheba Medical Center in Israel in different COVID-19 units, including an intensive care unit (ICU) and internal medicine unit (IMU). The study examines the impact of the diverse design layouts of the different units associated with the implementation of digital technologies for remote care on patient and staff safety. The results demonstrate the challenges and opportunities of integrating inpatient telemedicine for critical and intermediate care to enhance patient and staff safety. We contribute insights into the design of hospital units to support new models of remote care and suggest implications for Evidence-based Design (EBD), which will guide much needed future research.

Telemedicine Implementation in COVID-19 ICU: Balancing Physical and Virtual Forms of Visibility

Objective:

This case study examines the implementation of inpatient telemedicine in COVID-19 intensive care units (ICUs) and explores the impact of shifting forms of visibility on the management of the unit, staff collaboration, and patient care.

Background:

The COVID-19 crisis drove healthcare institutions to rapidly develop new models of care based on integrating digital technologies for remote care with transformations in the hospital-built environment. The Sheba Medical Center in Israel created COVID-19 ICUs in an underground structure with an open-ward layout and telemedicine control rooms to remotely supervise, communicate, and support the operations in the contaminated zones. One unit had a physical visual connection between the control room and the contaminated zone through a window, while the other had only a virtual connection with digital technologies.

Methods:

The findings are based on semistructured interviews with Sheba medical staff, telemedicine companies, and the architectural design team and observations at the COVID-19 units during March–August 2020.

Results:

The case study illustrates the implications of virtual and physical visibility on the management of the unit, staff collaboration, and patient care. It demonstrates the correlations between patterns of visibility and the users’ sense of control, orientation in space, teamwork, safety, quality of care, and well-being.

Conclusions:

The case study demonstrates the limitations of current telemedicine technologies that were not designed for inpatient care to account for the spatial perception of the unit and the dynamic use of the space. It presents the potential of a hybrid model that balances virtual and physical forms of visibility and suggests directions for future research and development of inpatient telemedicine.
