Clinical trials

Over the past two decades, the rapid advancement of critical care medicine has significantly reduced short-term mortality among critically ill patients. However, a growing number of intensive care unit (ICU) survivors experience persistent physical, cognitive, and psychological impairments after hospital discharge, a syndrome termed post-intensive care syndrome (PICS). Although PICS has gained increasing attention in recent years, existing studies still have multiple limitations. Given the continuously increasing number of ICU survivors in China and the marked heterogeneity in critical care delivery models across different regions and healthcare institutions, there is an urgent need for large-scale multicenter observational studies to systematically characterize the epidemiological features, multidimensional functional impairment profiles, and clinical impact of PICS in Chinese patients, thereby providing an evidence-based foundation for the development of a scientific post-ICU continuum of care.

This study aims to compare the efficacy and safety of the Speaking Valve trial versus the traditional Capping trial as indicators for tracheostomy decannulation in stroke patients. The trial is a prospective, multicenter, randomized, parallel-group, outcomes-assessor-blinded study with an exploratory crossover design.

Post-intensive care syndrome (PICS) is characterized by persistent physical, cognitive, and psychological impairments among survivors of critical illness. Although advances in intensive care medicine have reduced mortality, a large proportion of ICU survivors experience long-term functional impairments after discharge. High-dependency units (HDUs) serve as transitional care settings between intensive care units and general wards. Many critically ill survivors who cannot directly return home are transferred to HDU for continued treatment and rehabilitation. However, evidence regarding systematic multidisciplinary rehabilitation interventions in HDU settings remains limited. This prospective single-center interventional study aims to evaluate the effects of an integrated multidisciplinary rehabilitation model implemented in the HDU on physical, cognitive, and psychological outcomes among patients with post-intensive care syndrome. All enrolled patients will receive standardized integrated medical, nursing, and rehabilitation interventions. Multidimensional functional assessments will be conducted at baseline, during hospitalization, and before discharge from the HDU.

Background: International studies have proposed a cough peak flow (CPF) of ≥160 L/min as a reference threshold for safe decannulation. However, this measurement requires prior removal of the tracheostomy tube, which is often difficult for Chinese patients and their families to accept due to cultural and safety concerns. Additionally, there is a lack of rapid, user-friendly, and widely applicable quantitative tools in clinical practice within ICUs or rehabilitation specialties in China. Moreover, the heterogeneity among domestic patient populations with different underlying conditions (such as neuromuscular diseases, spinal cord injuries, stroke, and respiratory failure) makes it challenging to apply a single foreign-derived indicator. In our center's prospective study from 2019 to 2022(Respiratory Research 2024;25:128), the investigators proposed and preliminarily validated that a cough flow measured with tracheostomy tube and speaking valve (CFSV) \>100 L/min could serve as a threshold for safe decannulation. Among 193 patients with long-term tracheostomy tubes, 105 were decannulated based on this threshold, with a success rate of 98.1%. Only two cases required reintubation within 48 hours (1.9%), and the six-month reintubation rate was 2.9%, which is significantly better than previously reported domestic and international data (reintubation rates of 5-15%). For patients with insufficient CFSV, after an average of 26 days of individualized cough enhancement rehabilitation, 91% achieved the threshold and ultimately succeeded in decannulation. This suggests that 100 L/min may be a more physiologically appropriate threshold for Chinese (and even East Asian) populations with indwelling tracheostomy tubes, and that CFSV combined with systematic rehabilitation interventions can significantly improve decannulation rates. However, these conclusions are derived from single-center data with a limited sample size, and the diversity of diseases and regional variations in medical standards may affect generalizability. Therefore, there is an urgent need for multicenter, large-sample prospective studies to validate the effectiveness, accuracy, and feasibility of CFSV \>100 L/min as a quantitative standard for safe decannulation.
