RESUMO
Introduction: The Society of Critical Care Medicine Tele-Critical Care (TCC) Committee has identified the need for rigorous comparative research of different TCC delivery models to support the development of best practices for staffing, application, and approaches to workflow. Our objective was to describe and compare outcomes between two TCC delivery models, TCC with 24/7 Bedside Intensivist (BI) compared with TCC with Private Daytime Attending Intensivist (PI) in relation to intensive care unit (ICU) and hospital mortality, ICU and hospital length of stay (LOS), cost, and complications across the spectrum of routine ICU standards of care. Methods: Observational cohort study at large health care system in 12 ICUs and included patients, ≥18, with Acute Physiology and Chronic Health Evaluation (APACHE) IVa scores and predictions (October 2016-June 2019). Results: Of the 19,519 ICU patients, 71.7% (n = 13,993) received TCC with 24/7 BI while 28.3% (n = 5,526) received TCC with PI. ICU and Hospital mortality (4.8% vs. 3.1%, p < 0.0001; 12.6% vs. 8.1%, p < 0.001); and ICU and Hospital LOS (3.2 vs. 2.4 days, p < 0.001; 9.8 vs. 7.2 days, p < 0.001) were significantly higher among 24/7 BI compared with PI. The APACHE observed/expected ratios (odds ratio [OR]; 95% confidence interval [CI]) for ICU mortality (0.62; 0.58-0.67) vs. (0.53; 0.46-0.61) and Hospital mortality (0.95; 0.57-1.48) vs. (0.77; 0.70-0.84) were significantly different for 24/7 BI compared with PI. Multivariate mixed models that adjusted for confounders demonstrated significantly greater odds of (OR; 95% CI) ICU mortality (1.58; 1.28-1.93), Hospital mortality (1.52; 1.33-1.73), complications (1.55; 1.18-2.04), ICU LOS [3.14 vs. 2.59 (1.25; 1.19-1.51)], and Hospital LOS [9.05 vs. 7.31 (1.23; 1.21-1.25)] among 24/7 BI when compared with PI. Sensitivity analyses adjusting for ICU admission within 24 h of hospital admission, receiving active ICU treatments, nighttime admission, sepsis, and highest third acute physiology score indicated significantly higher odds for 24/7 BI compared with PI. Conclusion: Our comparison demonstrated that TCC delivery model with PI provided high-quality care with significant positive effects on outcomes. This suggests that TCC delivery models have broad-ranging applicability and benefits in routine critical care, thus necessitating progressive research in this direction.

INTRODUCTION: Remotely tele-mentored ultrasound (RTMUS) involves the real-time guidance of US-naïve providers as they perform point-of-care ultrasound (POCUS) by remotely located, US-proficient providers via telemedicine. The concordance between RTMUS and POCUS in the evaluation of critically ill patients has not been reported. This study sought to evaluate the concordance between RTMUS and POCUS for the cardiopulmonary evaluation of patients in acute respiratory insufficiency and/or shock. METHODS: Ultrasound-naÏve nurses performed RTMUS on critically ill patients. Concordance between RTMUS and POCUS (performed by critical care fellows) in the evaluation of the heart and lungs was reported. The test characteristics of RTMUS were calculated using POCUS as a gold standard. Concordance between RTMUS and available transthoracic echocardiography (TTE) and computed tomography (CT) scans was also reported. RESULTS: Twenty patients were enrolled. Concordance between RTMUS and POCUS was good (90%-100%) for left ventricle function, right ventricle (RV) dilatation/dysfunction, pericardial effusion, lung sliding, pulmonary interstitial syndrome, pleural effusion, and fair (80%) for lung consolidation. Concordance between RTMUS and TTE or CT was similar. RTMUS was highly specific (88%-100%) for all abnormalities evaluated and highly sensitive (89%-100%) for most abnormalities although sensitivity for the detection of RV dilatation/dysfunction (33%) and pulmonary interstitial syndrome (71%) was negatively impacted by false negatives. CONCLUSIONS: RTMUS may be a reasonable substitute for POCUS in the cardiopulmonary evaluation of patients with acute respiratory insufficiency and/or shock. These findings should be validated on a larger scale.

BACKGROUND: Nurses and other non-physician providers have demonstrated proficiency at obtaining images in the tele-ultrasound system. However, use of this skill requires comfort with the procedure and willingness to incorporate it into practice. OBJECTIVES: To assess 1) level of comfort of non-physician providers performing tele-ultrasound before and after brief training and 2) feasibility of implementing an educational programme that improves level of comfort. METHODS: Feasibility study including a brief training session followed by hands-on tele-ultrasound. The pilot cohort performed tele-ultrasound on a healthy volunteer. The clinical cohort performed tele-ultrasound on criticalli ill patients with shock or respiratory failure. Remote intensivists provided real-time guidance via tele-medicine technology. Each participant completed a survey assessing training experience and level of comfort before and after training. RESULTS: Sixteen non-physician providers participated. All participants agreed that the training session prepared them for image acquisition and that the training experience was positive. The number of participants comfortable with ultrasound improved significantly (before vs. after training: 5/16 [31%] vs. 16/16 [100%], mean Likert score 2.7 vs. 4.8, pâ¯=â¯0.001). CONCLUSIONS: After brief training, participants could comfortably perform tele-ultrasound and were more willing to incorporate it into tele-ICU-directed care. Results support conducting a larger-scale trial of tele-US to assess clinical utility.

PURPOSE: Remote telementored ultrasound (RTMUS) systems can deliver ultrasound (US) expertise to regions lacking highly trained bedside ultrasonographers and US interpreters. To date, no studies have evaluated the quality and clinical utility of US images transmitted using commercially available RTMUS systems. METHODS: This prospective pilot evaluated the quality of US images (right internal jugular vein, lung apices and bases, cardiac subxiphoid view, bladder) obtained using a commercially available iPad operating FaceTime software. A bedside non-physician obtained images and a tele-intensivist interpreted them. All US screen images were simultaneously saved on the US machine and captured via a FaceTime screen shot. The tele-intensivist and an independent US expert rated image quality and utility in guiding clinical decisions. RESULTS: The tele-intensivist rated FaceTime images as high quality (90% [69/77]) and could comfortably make clinical decisions using these images (96% [74/77]). Image quality did not differ between FaceTime and US images (97% (75/77). Strong inter-rater reliability existed between tele-intensivist and US expert evaluations (Spearman's rho 0.43; P<.001). CONCLUSION: An RTMUS system using commercially available two-way audiovisual technology can transmit US images without quality degradation. For most anatomic sites assessed, US images acquired using FaceTime are not inferior to those obtained directly with the US machine.

PURPOSE: Intensive care unit telemedicine (tele-ICU) uses audiovisual systems to remotely monitor and manage patients. Intensive care unit ultrasound can augment an otherwise limited bedside evaluation. To date, no studies have utilized tele-ICU technology to assess the quality and clinical use of real-time ultrasound images. We assessed whether tele-intensivists can instruct nonphysicians to obtain high-quality, clinically useful ultrasound images. METHODS: This prospective pilot evaluated the effectiveness of a brief educational session of nonphysician "ultrasonographers" on their ability to obtain ultrasound images (right internal jugular vein, bilateral lung apices and bases, cardiac subxiphoid view, bladder) with real-time tele-intensivist guidance. All ultrasound screen images were simultaneously photographed with a 2-way camera and saved on the ultrasound machine. The tele-intensivist assessed image quality, and an independent ultrasound expert rated their use in guiding clinical decisions. RESULTS: The intensivist rated the tele-ICU camera images as high quality (70/77, 91%) and suitable for guiding clinical decisions (74/77, 96%). Only bilateral lung apices demonstrated differences in quality and clinical use. All other images were rated noninferior and clinically useful. CONCLUSION: Tele-intensivists can guide minimally trained nonphysicians to obtain high-quality, clinically useful ultrasound images. For most anatomic sites, tele-ICU images are of similar quality to those acquired directly by ultrasound.

Telemedicine has been increasingly used in the intensive care unit setting (Tele-ICU) for providing care. Given the shortage of qualified intensivists and critical care nurses in the United States and the ever-increasing demand for intensive care services, Tele-ICU has been proposed as a strategy to bridge this supply/demand gap. The Tele-ICU staffing model provides for many important outcome benefits that have been evaluated over the years by several studies. In this review, the authors summarize the existing evidence and identify areas where further evaluation is warranted.
