Objectives: Implement a connected network between two Tele-ICU programs to support staffing and rounding during the first wave of the coronavirus disease 2019 pandemic in the United States.

Design: Proof of Concept model.

Setting: Northwell Health; a 23 Hospital, 40 ICU (500 ICU beds) healthcare organization serving the downstate NY area.

Objective: To determine whether rapid administration of a crystalloid bolus of 30 mL/kg within 3 hours of presentation harms or benefits hypotensive patients with sepsis with a history of congestive heart failure (CHF).

Patients And Methods: A retrospective cohort study using Medicare claims data enhanced by medical record data from members of the High Value Healthcare Collaborative from July 1, 2013, to June 30, 2015, examining patients with a history of CHF who did (fluid bundle compliant [FBC]) or did not (NFBC) receive a volume bolus of 30 mL/kg within 3 hours of presentation to the emergency department. A proportional Cox hazard model was used to evaluate the association of FBC with 1-year survival.

Background: Current patient satisfaction assessment results are delayed and obtained from select patient surveys. As a result, these assessments may not represent the experience of the entire patient population. This study developed a method to measure and evaluate all patients' experiences while they are within the care episode and link it to processes within the organisation.

Background: Differences between hospital-presenting sepsis (HPS) and emergency department-presenting sepsis (EDPS) are not well described.

Objectives: We aimed to (1) quantify the prevalence of HPS versus EDPS cases and outcomes; (2) compare HPS versus EDPS characteristics at presentation; (3) compare HPS versus EDPS in process and patient outcomes; and (4) estimate risk differences in patient outcomes attributable to initial resuscitation disparities.

Design: Retrospective consecutive-sample cohort.

Objectives: The prevalence of responsiveness to initial fluid challenge among hypotensive sepsis patients is unclear. To avoid fluid overload, and unnecessary treatment, it is important to differentiate these phenotypes. We aimed to 1) determine the proportion of hypotensive sepsis patients sustaining favorable hemodynamic response after initial fluid challenge, 2) determine demographic and clinical risk factors that predicted refractory hypotension, and 3) assess the association between timeliness of fluid resuscitation and refractoriness.

Objectives: The objectives of this study were to 1) assess patterns of early crystalloid resuscitation provided to sepsis and septic shock patients at initial presentation and 2) determine the association between time to initial crystalloid resuscitation with hospital mortality, mechanical ventilation, ICU utilization, and length of stay.

Design: Consecutive-sample observational cohort.

Setting: Nine tertiary and community hospitals over 1.

Objective: To compare the association of 3-h sepsis bundle compliance with hospital mortality in non-hypotensive sepsis patients with intermediate versus severe hyperlactemia.

Methods: This was a cohort study of all non-hypotensive, hyperlactemic sepsis patients captured in a prospective quality-improvement database, treated October 2014 to September 2015 at five tertiary-care centers. We defined sepsis as 1) infection, 2) ≥2 SIRS criteria, and 3) ≥1 organ dysfunction criterion.

Objectives: To determine mortality and costs associated with adherence to an aggressive, 3-hour sepsis bundle versus noncompliance with greater than or equal to one bundle element for severe sepsis and septic shock patients.

Design: Prospective, multisite, observational study following three sequential, independent cohorts, from a single U.S.

Study Objective: We evaluate the association of intravenous fluid resuscitation initiation within 30 minutes of severe sepsis or septic shock identification in the emergency department (ED) with inhospital mortality and hospital length of stay. We also compare intravenous fluid resuscitation initiated at various times from severe sepsis or septic shock identification's association with the same outcomes.

Methods: This was a review of a prospective, observational cohort of all ED severe sepsis or septic shock patients during 13 months, captured in a performance improvement database at a single, urban, tertiary care facility (90,000 ED visits/year).

Background: As part of a zero-tolerance approach to preventable deaths, North Shore-LIJ Health System (North Shore-LIJ) leadership prioritized a major patient safety initiative to reduce sepsis mortality in 2009 across 10 acute care hospitals (an 11th joined later). At baseline (2008), approximately 3,500 patients were discharged with a diagnosis of sepsis, which ranked as the top All Patient Refined Diagnosis-Related Group by number of deaths (N = 883). Initially, the focus was sepsis recognition and treatment in the emergency departments (EDs).

Objective: To examine whether a supplemental remote intensive care unit (ICU) care program, implemented by an integrated delivery network using a commercial telemedicine and information technology system, can improve clinical and economic performance across multiple ICUs.

Design: Before-and-after trial to assess the effect of adding the supplemental remote ICU telemedicine program.

Setting: Two adult ICUs of a large tertiary care hospital.
