    Abstract:
    OBJECTIVES: Although the current coronavirus disease 2019 pandemic demonstrates the urgent need for the integration of tele-ICUs, there is still a lack of uniform regulations regarding the level of authority. We conducted a systematic review and meta-analysis to evaluate the impact of the level of authority in tele-ICU care on patient outcomes. DATA SOURCES: We searched MEDLINE, EMBASE, CENTRAL, and Web of Science from inception until August 30, 2020. STUDY SELECTION: We searched for randomized controlled trials and observational studies comparing standard care plus tele-ICU care with standard care alone in critically ill patients. DATA EXTRACTION: Two authors performed data extraction and risk of bias assessment. Mean differences and risk ratios were calculated using a random-effects model. DATA SYNTHESIS: A total of 20 studies with 477,637 patients (ntele-ICU care = 292,319, ncontrol = 185,318) were included. Although "decision-making authority" as the level of authority was associated with a significant reduction in ICU mortality (pooled risk ratio, 0.82; 95% CI, 0.71-0.94; p = 0.006), we found no advantage of tele-ICU care in studies with "expert tele-consultation" as the level of authority. With regard to length of stay, "decision-making authority" resulted in an advantage of tele-ICU care (ICU length of stay: pooled mean difference, -0.78; 95% CI, -1.46 to -0.10; p = 0.14; hospital length of stay: pooled mean difference, -1.54; 95% CI, -3.13 to 0.05; p = 0.06), whereas "expert tele-consultation" resulted in an advantage of standard care (ICU length of stay: pooled mean difference, 0.31; 95% CI, 0.10-0.53; p = 0.005; hospital length of stay: pooled mean difference, 0.58; 95% CI, -0.04 to 1.21; p = 0.07). CONCLUSIONS: In contrast to expert tele-consultations, decision-making authority during tele-ICU care reduces mortality and length of stay in the ICU. This work confirms the urgent need for evidence-based ICU telemedicine guidelines and reveals potential benefits of uniform regulations regarding the level of authority when providing tele-ICU care.
