Hospital census prediction has well-described implications for efficient hospital resource utilization, and recent issues with hospital crowding due to CoVID-19 have emphasized the importance of this task. Our team has been leading an institutional effort to develop machine-learning models that can predict hospital census 12 hours into the future. We describe our efforts at developing accurate empirical models for this task. Ultimately, with limited resources and time, we were able to develop simple yet useful models for 12-hour census prediction and design a dashboard application to display this output to our hospital's decision-makers. Specifically, we found that linear models with ElasticNet regularization performed well for this task with relative 95% error of +/- 3.4% and that this work could be completed in approximately 7 months.

Urban traffic accidents in Isfahan city: a study of prehospital response time intervals.
Int J Emerg Med
December 2024
Department of Neurosurgery, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran.
Introduction: Traffic accidents are a major public health concern worldwide, resulting in significant injuries, fatalities, and economic costs. In urban zones, traffic accident dynamics can vary significantly due to population density, infrastructure, and emergency response capabilities. The present study was conducted to determine the time intervals of prehospital emergencies in traffic accidents by separating the 15 zones of Isfahan city, Iran.

Eur J Emerg Med
February 2025
AP-HP, Département de santé publique, Hôpital universitaire Henri Mondor.
Background And Importance: Prolonged emergency medical services' response times (EMS-RT) are associated with poorer outcomes in out-of-hospital cardiac arrest (OHCA). The patient access time interval (PATI), from vehicle stop until contact with patient, may be increased in areas with low socioeconomic status (SES).
Objectives: The objective of this study is to identify predictors of prolonged EMS-RT intervals, and to evaluate associations with clinical outcomes in OHCAs occurring in the largest metropolitan area in France.
Article Synopsis
- This study explores patterns of functional impairment in New Zealand, focusing on how it differs based on factors like non-communicable diseases (NCDs), age, sex, ethnicity, and living conditions.
- Using a national database from 2018, researchers found that about 29% of the population had at least one NCD, with significant increases in activity limitations linked to the number of NCDs a person had.
- Individuals with conditions like dementia and stroke experienced the highest activity limitations, especially among Māori and Pacific peoples, highlighting the need for better NCD prevention and disability support.
The mental health care system for children and adolescents in Greece: a review and structure assessment.
Front Health Serv
December 2024
Child and Adolescent Mental Health Initiative (CAMHI), Stavros Niarchos Foundation & Child Mind Institute, Athens, Greece.
Background: The mental health system in Greece faces challenges to complete its transition to a community-oriented model, having significant concerns for child and adolescent care due to lower coverage and service gaps. This component of the mental health system has not been comprehensively evaluated.
Methods: We conducted a review of the mental health care system for children and adolescents in Greece.
Socio-Economic Inequities in the Age-Specific Burden of Severe Respiratory Syncytial Virus (RSV) in Canada, 2016-2019.
J Infect Dis
December 2024
Public Health Ontario, Toronto, ON, Canada.
Background: Socio-economic status (SES) is an important determinant of severe respiratory infections. Despite being a leading cause of hospitalization, limited attention has been given to social inequities in respiratory syncytial virus (RSV), particularly outside of childhood and beyond neighbourhood-level measures. This study aimed to quantify the burden of severe RSV disease across the age continuum by individual-level SES indicators.
