A retrospective cohort study of age-based differences in the care of hospitalized patients with sudden clinical deterioration.
The proportion of elderly patients is increasing, but it is unknown if there are age-based differences in care of hospitalized patients with sudden clinical deterioration. We sought to examine the relation between patient age and care for hospitalized patients experiencing sudden clinical deterioration. ⋯ Patient age is associated with care for hospitalized patients with sudden clinical deterioration, suggesting that strategies to guide care of elderly patients during MET activation may be beneficial.

Observational StudyMortality in chronically critically ill patients: Expanding the use of the ProVent score.
The purpose of the study is to look at the performance of the Prognosis for Prolonged Ventilation (ProVent) score with a short-term outcome as well as when used earlier during the course of prolonged mechanical ventilation (MV). ⋯ The ProVent score can be used for short-term prognosis (mortality in the ICU) and earlier in the evaluation of CCI patients.

Indexation of cardiac output to biometric parameters in critically ill patients: A systematic analysis of a transpulmonary thermodilution-derived database.
Cardiac output (CO) (liters per minute) is usually normalized (ie, indexed) to the patient's body surface area (BSA) resulting in the hemodynamic variable cardiac index (CI) (liters per minute per square meter). We aimed (1) to evaluate the impact of different body weight-based CO indexations on the resulting CI values and (2) to identify biometric parameters independently associated with CO in critically ill patients. ⋯ The indexation of CO to BSA is highly dependent on the body weight estimation formula used to calculate BSA. Cardiac output is independently associated with the biometric factors age, height, and BWact. These factors might be considered for indexation of CO.

Observational StudyPatient-ventilator asynchrony affects pulse pressure variation prediction of fluid responsiveness.
During partial ventilatory support, pulse pressure variation (PPV) fails to adequately predict fluid responsiveness. This prospective study aims to investigate whether patient-ventilator asynchrony affects PPV prediction of fluid responsiveness during pressure support ventilation (PSV). ⋯ Patient-ventilator asynchrony affects PPV performance during partial ventilatory support influencing its efficacy in predicting fluid responsiveness.

Development and validation of electronic surveillance tool for acute kidney injury: A retrospective analysis.
Timely detection of acute kidney injury (AKI) facilitates prevention of its progress and potentially therapeutic interventions. The study objective is to develop and validate an electronic surveillance tool (AKI sniffer) to detect AKI in 2 independent retrospective cohorts of intensive care unit (ICU) patients. The primary aim is to compare the sensitivity, specificity, and positive and negative predictive values of AKI sniffer performance against a reference standard. ⋯ Acute kidney injury can reliably and accurately be detected electronically in ICU patients. The presented method is applicable for both clinical (decision support) and research (enrollment for clinical trials) settings. Prospective validation is required.
