AI Article Synopsis
- - The study aimed to evaluate how effective nursing handoff notes are in identifying underreported cases of hospital-acquired pressure injuries (HAPI) in a pediatric hospital setting.
- - Researchers developed a workflow, using natural language processing and machine learning models, to analyze over 70,000 nursing notes, achieving high sensitivity and providing accurate identification of HAPI events.
- - Their findings indicate that this method of surveillance for HAPI is not only feasible but also effective, identifying a notable incidence of injuries that may otherwise go unreported.
Article Abstract
Objective: This study assessed the feasibility of nursing handoff notes to identify underreported hospital-acquired pressure injury (HAPI) events.
Methods: We have established a natural language processing-assisted manual review process and workflow for data extraction from a corpus of nursing notes across all medical inpatient and intensive care units in a tertiary care pediatric center. This system is trained by 2 domain experts. Our workflow started with keywords around HAPI and treatments, then regular expressions, distributive semantics, and finally a document classifier. We generated 3 models: a tri-gram classifier, binary logistic regression model using the regular expressions as predictors, and a random forest model using both models together. Our final output presented to the event screener was generated using a random forest model validated using derivation and validation sets.
Results: Our initial corpus involved 70,981 notes during a 1-year period from 5484 unique admissions for 4220 patients. Our interrater human reviewer agreement on identifying HAPI was high ( κ = 0.67; 95% confidence interval [CI], 0.58-0.75). Our random forest model had 95% sensitivity (95% CI, 90.6%-99.3%), 71.2% specificity (95% CI, 65.1%-77.2%), and 78.7% accuracy (95% CI, 74.1%-83.2%). A total of 264 notes from 148 unique admissions (2.7% of all admissions) were identified describing likely HAPI. Sixty-one described new injuries, and 64 describe known yet possibly evolving injuries. Relative to the total patient population during our study period, HAPI incidence was 11.9 per 1000 discharges, and incidence rate was 1.2 per 1000 bed-days.
Conclusions: Natural language processing-based surveillance is proven to be feasible and high yield using nursing handoff notes.

Background: We aimed to identify the central lifestyle, the most impactful among lifestyle factor clusters; the central health outcome, the most impactful among health outcome clusters; and the bridge lifestyle, the most strongly connected to health outcome clusters, across 29 countries to optimise resource allocation for local holistic health improvements.
Methods: From July 2020 to August 2021, we surveyed 16 461 adults across 29 countries who self-reported changes in 18 lifestyle factors and 13 health outcomes due to the pandemic. Three networks were generated by network analysis for each country: lifestyle, health outcome, and bridge networks.

The cortex and cerebellum are densely connected through reciprocal input/output projections that form segregated circuits. These circuits are shown to differentially connect anterior lobules of the cerebellum to sensorimotor regions, and lobules Crus I and II to prefrontal regions. This differential connectivity pattern leads to the hypothesis that individual differences in structure should be related, especially for connected regions.

The digital infrastructure has profoundly changed people's daily lives and health outcomes. However, the causal effect of digital infrastructure on cognitive health remains unclear. The study employs the "Broadband China" policy as a reliable proxy for digital infrastructure, using the China Health and Retirement Longitudinal Study (CHARLS) five waves panel data from 2011 to 2020 and a staggered difference-in-differences (DID) method to investigate the causal impact of digital infrastructure construction on the cognitive health in Chinese older adults.

Background: Bias in letters of recommendation may have an impact on assessment of the cardiothoracic surgical applicant. Letters written for fellowship candidates might differ on the basis of the applicant's gender, although prior investigations have not explored this population. We aimed to evaluate gender differences in letters of recommendation written for cardiothoracic surgery applicants.
