Article Synopsis
  • - The study focuses on improving prediction of hospital-acquired pressure injuries (HAPIs) in intensive care units (ICUs) by developing an artificial intelligence (AI) risk-assessment model that addresses the limitations of traditional tools, which often miss critical ICU-specific data.
  • - Researchers used clinical data from over 28,000 ICU patients to create an ensemble AI model that achieved a predictive accuracy of 0.80 and developed an explainer dashboard to visualize the model's findings, making it easier for clinicians to understand.
  • - The resulting AI risk-assessment system aims to provide transparent and interpretable insights for healthcare providers, potentially leading to better preventive measures for HAPIs in ICU settings.

Objective: To compare movement associated with position changes among nursing home residents who remain in lying versus upright positions for more than 2 hours and among residents living with obesity, dementia, or neither condition.

Methods: The authors conducted a descriptive exploratory study using secondary data (N = 934) from the Turn Everyone And Move for Ulcer Prevention (TEAM-UP) clinical trial to examine transient movements (<60 seconds) within prolonged periods of 2 to 5 hours without repositioning.

Results: Nursing home residents exhibit significantly more episodic transient movements when upright than lying.

Pressure injury (PrI) prevention guidelines recommend 2-h repositioning intervals in healthcare settings, requiring significant nursing time investment. We analysed the cost-effectiveness of PrI prevention protocols with 2-, 3- and 4-h repositioning intervals in US nursing homes according to 'Turn Everyone and Move for Ulcer Prevention' (TEAM-UP) randomized controlled trial findings. Markov modelling compared 2-, 3- and 4-h repositioning intervals, controlling for other practice guidelines, to prevent PrIs in nursing home residents from a US health sector perspective over one year using TEAM-UP trial data for model structure, sampling and parameterization.

Background: Cardiothoracic surgery patients have an increased risk for aspiration and may require enteral access for nutrition.

Local Problem: In a cardiothoracic intensive care unit, feeding start times were delayed because of scheduling conflicts with support services. An electromagnetic device (Cortrak 2 Enteral Access System, Avanos Medical) was introduced to allow advanced practice providers (nurse practitioners and physician assistants) to independently establish postpyloric access and reduce dependence on ancillary services.

Nursing staff assessment to accurately identify pressure injury (PrI) risk is a hallmark in PrI prevention care. Risk scores from the Braden Scale for Predicting Pressure Sore Risk (hereafter Braden), a commonly used tool for assessing PrI risk, signal the need for preventative care. Braden Mobility, Activity, and Sensory Perception subscale subgroups associated with repositioning movement features help identify preventative strategies that minimize pressure intensity and duration.

Article Synopsis
  • The study analyzed movement patterns in nursing home residents using 28 days of accelerometer data from 1,100 individuals in a clinical trial focused on ulcer prevention.
  • Findings showed that residents changed positions for longer durations (prolonged events) nearly three times per hour, while shorter movements (transient events) occurred almost eight times an hour, with the least activity during night shifts.
  • The results highlight complex movement behaviors in residents, providing valuable insights for understanding pressure injury prevention and how residents naturally move in their daily lives.

Article Synopsis
  • Nurses in busy critical care settings often struggle with keeping up with routine repositioning schedules for patients at risk of pressure injuries.
  • A study tested the effectiveness of wearable sensors that provide visual cues to improve compliance with a two-hour repositioning protocol in a medical ICU.
  • Results showed compliance jumped from 55% to 89% with the use of the sensors, indicating that visual cueing significantly helps nurses to meet repositioning needs and improves teamwork.

Objective: To investigate the clinical effectiveness of three nursing-home-wide repositioning intervals (2-, 3-, or 4-hour) without compromising pressure injury (PrI) incidence in 4 weeks.

Methods: An embedded pragmatic cluster randomized controlled trial was conducted in nine nursing homes (NHs) that were randomly assigned to one of three repositioning intervals. Baseline (12 months) and 4-week intervention data were provided during the TEAM-UP (Turn Everyone And Move for Ulcer Prevention) study.

Compression of the soft tissue between a support surface and a bony prominence has long been the accepted primary mechanism of pressure injury (PrI) formation, with the belief that said compression leads to capillary occlusion, ischemia, and tissue necrosis. This explanation presupposes an "outside-in" pathophysiologic process of tissue damage originating at the local capillary level. Despite advances in prevention protocols, there remains a stubbornly consistent incidence of severe PrIs including deep-tissue injuries, the latter usually evolving into stage 4 PrIs with exposed bone or tendon.

Background: Hospital-acquired pressure injuries (HAPrIs) are areas of damage to the skin occurring among 5-10% of surgical intensive care unit (ICU) patients. HAPrIs are mostly preventable; however, prevention may require measures not feasible for every patient because of the cost or intensity of nursing care. Therefore, recommended standards of practice include HAPrI risk assessment at routine intervals.

Purpose: Community-acquired pressure injuries (CAPIs) are present among approximately 3% to 8% of patients admitted to acute care hospitals. In the critical care population, little is known about hospital-acquired pressure injury (HAPI) development among patients with CAPIs because most studies exclude patients with CAPIs. The purpose of our study was to determine the incidence of HAPI development and the associated risk factors among surgical critical care patients with CAPIs.
