Background: This study evaluates the characteristics and outcome of patients admitted to the ICU following bariatric surgery.
Methods: Descriptive study. A review of a prospectively collected database of our bariatric surgery procedures from 2003 until 2006 was performed. The study was performed in a tertiary level, mixed medical and surgical, adult ICU of a large referral hospital.
Results: Of the 265 patients undergoing bariatric surgery (mainly gastroplasties and Roux-en-Y gastric bypasses), 22 (8%) were admitted to the ICU, of which 14 (64%) were on an elective basis and eight (36%) emergently. Hospital length of stay (LOS) for all patients was 4.5 days and ICU LOS was 12 days. Most elective admissions were standard procedure because of obstructive sleep apnea (OSA) or super obesity, with a median ICU stay of 1 day. Emergent admissions were mainly done after emergent surgery due to surgical complications and had a median ICU stay of 8 days. Only two patients needed intensive care for more than 3 days. There were no deaths during ICU stay.
Conclusions: The ICU admission rate in our report is 8%. This study showed that 32 ICU days are needed per 100 diverse bariatric procedures. Most patients are admitted to the ICU for only a few days and the majority of the admissions is planned.

Unsupervised machine learning analysis to identify patterns of ICU medication use for fluid overload prediction.
Pharmacotherapy

Department of Clinical and Administrative Pharmacy, University of Georgia College of Pharmacy, Athens, Georgia, USA.
Background: Fluid overload (FO) in the intensive care unit (ICU) is common, serious, and may be preventable. Intravenous medications (including administered volume) are a primary cause for FO but are challenging to evaluate as a FO predictor given the high frequency and time-dependency of their use and other factors affecting FO. We sought to employ unsupervised machine learning methods to uncover medication administration patterns correlating with FO.

Background: Medical mistrust may worsen communication between ICU surrogate decision-makers and intensivists. The prevalence of and risk factors for medical mistrust among surrogate decision-makers are not known.
Research Question: What are the potential sociodemographic risk factors for high medical mistrust among surrogate decision-makers of critically ill patients at high risk of death?
Study Design And Methods: In this pilot cross-sectional study conducted at a single academic medical center between August 2022 and August 2023, adult patients admitted to the medical ICU and their surrogate decision-makers were enrolled.
Real-time estimated Sequential Organ Failure Assessment (SOFA) score with intervals: improved risk monitoring with estimated uncertainty in health condition for patients in intensive care units.
Health Inf Sci Syst

Department of Cardiac, Thoracic and Vascular Surgery, National University Hospital, Singapore, Singapore.
Purpose: Real-time risk monitoring is critical but challenging in intensive care units (ICUs) due to the lack of real-time updates for most clinical variables. Although real-time predictions have been integrated into various risk monitoring systems, existing systems do not address uncertainties in risk assessments. We developed a novel framework based on commonly used systems like the Sequential Organ Failure Assessment (SOFA) score by incorporating uncertainties to improve the effectiveness of real-time risk monitoring.
