Objective: The purpose of this study was to investigate the risk factors associated with postoperative pulmonary complications(PPCs) in critically ill patients transferred to intensive care unit(ICU) after abdominal surgery and develop a predictive model for this disease.

Methods: Data for 3716 patients who were admitted to ICU after abdominal surgery in Peking University People's Hospital between January 2015 and December 2020 were retrospectively collected and analyzed to identify the risk factors and develop a nomogram prediction model. Data for patients admitted to ICU following abdominal surgery at Peking University People's Hospital from March 2021 to December 2022 were prospectively collected as a validation set to validate and assess the model.

Article Synopsis
  • The study investigates postoperative pulmonary complications (PPCs) in critical patients after hepatectomy, aiming to identify risk factors and develop a predictive nomogram.
  • Data from 503 patients were analyzed using multivariate logistic regression, revealing independent risk factors such as advanced age, higher body mass index, lower preoperative serum albumin levels, and first-day ICU infusion volumes.
  • The resulting nomogram demonstrated a satisfactory predictive ability with an AUC of 0.713, indicating its potential utility in predicting PPCs for at-risk patients.

The rate of intensive care unit (ICU) mortality in patients with hematologic malignancies is high. The risk factors for this were inconsistent across several previous studies, and there is currently no accepted consensus around risk factors for these patients. We aimed to identify which prognostic factors were associated with ICU mortality in critically ill patients with hematologic malignancies, nearly half of which were allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients.

Article Synopsis
  • - The study investigated the incidence and outcomes of Sepsis-3 in Yuetan sub-district, Beijing, aiming to estimate the disease burden in China, as data from middle-income countries are limited post the introduction of Sepsis-3.
  • - From July 2012 to June 2014, researchers reviewed medical records and found that of 21,191 hospitalized patients, 935 had Sepsis-3, leading to an annual incidence rate of 363 cases per 100,000 people.
  • - The study concluded that Sepsis-3 has a high case fatality rate of 32.0%, with males, the elderly, and those with more health issues being at higher risk; it estimated around 700

Article Synopsis
  • * A study analyzed ICU data from a tertiary-care hospital in China over two periods: no screening (2015-2016) versus targeted screening (2016-2017) based on patient risk factors.
  • * Results showed a significant decrease in CRE infection rates during the targeted screening period, with individualized surveillance associated with a lower infection rate, while other factors like APACHE II score and prior antimicrobial use were also identified as independent risks.

Background: In 2007, the Saline versus Albumin Fluid Evaluation-Translation of Research Into Practice Study (SAFE-TRIPS) reported that 0.9% sodium chloride (saline) and hydroxyethyl starch (HES) were the most commonly used resuscitation fluids in intensive care unit (ICU) patients. Evidence has emerged since 2007 that these fluids are associated with adverse patient-centred outcomes.

Background: Urine output (UO) is an essential criterion of the Kidney Disease Improving Global Outcomes (KDIGO) definition and classification system for acute kidney injury (AKI), of which the diagnostic value has not been extensively studied. We aimed to determine whether AKI based on KDIGO UO criteria (KDIGOUO) could improve the diagnostic and prognostic accuracy, compared with KDIGO serum creatinine criteria (KDIGOSCr).

Methods: We conducted a secondary analysis of the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a 2-month prospective cohort study (July 1, 2009 to August 31, 2009) involving 3063 patients in 22 tertiary Intensive Care Units in Mainland of China.

Background: Self-report pain assessment scales may be inappropriate when critically ill patients are incapable of adequate communication because of sedation or mechanical ventilation. The Behavioral Pain Scale (BPS, for intubated patients) and the BPS-non intubated (BPS-NI, for non-intubated patients) measure objective behavioral indicators of pain in non-communicating critically ill patients.

Objectives: To develop a Chinese version of the BPS combining the original version of the BPS and BPS-NI suitable for pain assessment among critically ill patients and to determine its reliability and validity.
