Background And Objectives: Patient and family violent outbursts toward staff, caregivers, or through self-harm, have increased during the ongoing behavioral health crisis. These health care-associated violence (HAV) episodes are likely under-reported. We sought to assess the feasibility of using nursing notes to identify under-reported HAV episodes.

- - 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.
Electronic surveillance of patient safety events using natural language processing.

Objective: We describe our approach to surveillance of reportable safety events captured in hospital data including free-text clinical notes. We hypothesize that a) some patient safety events are documented only in the clinical notes and not in any other accessible source; and b) large-scale abstraction of event data from clinical notes is feasible.
Materials And Methods: We use regular expressions to generate a training data set for a machine learning model and apply this model to the full set of clinical notes and conduct further review to identify safety events of interest.
We hypothesized that children with low socioeconomic status (SES) had disproportionately fewer eye care visits during the early COVID-19 pandemic and that these children would be less likely to use synchronous provider-to-patient telemedicine eye care visits. This study investigated changes in patient demographics at a large, academic pediatric eye center before and after the pandemic. A retrospective review of all visits from March 18, 2019, to May 31, 2019 (pre-COVID period) and of the same date range in 2020 (COVID period) was performed.

Design: Retrospective, cohort study.
