Socio-demographic and -economic factors associated with 30-day readmission for conditions targeted by the hospital readmissions reduction program: a population-based study

BMC Public Health, 2021
Background Early hospital readmissions remain common in patients with conditions targeted by the CMS Hospital Readmission Reduction Program (HRRP). There is still no consensus on whether readmission measures should be adjusted based on social factors ...

Assessing the Estimands and Estimates of Hospitalization Rates in Health Economics and Clinical Medicine

Health Economics, Volume 35, Issue 9, Page 1397-1405, September 2026.
ABSTRACT Even though data on hospital admissions are widely used in health research, hospitalization‐related estimands measured using these data are not always clearly conceptualized. Consequently, estimators of these quantities can have unclear rationales and undesirable properties.

Adaptively Segmenting Angular Sectors for Radar HRRP Automatic Target Recognition

EURASIP Journal on Advances in Signal Processing, 2008
In this paper the manifold geometry in radar high-resolution range profile (HRRP) is firstly explored, and then, according to the characteristics of target pose sensitivity, a method of adaptively segmenting the aspect sectors is proposed for HRRP ...

Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

The Effect of Rural Versus Urban Residence on Risk of Unplanned Readmission and Death in Older Veterans Discharged From VA Hospitals

The Journal of Rural Health, Volume 42, Issue 3, Summer 2026.
ABSTRACT Purpose Evidence suggests that rural‐residing adults—compared with urban—may be at greater risk of readmission and mortality. Operational leaders within the Department of Veterans Affairs (VA) Geriatric Learning Health System (GLHS) sought to understand the effects of rural residence on readmission and mortality risk for older Veterans ...

Rates of 30‐Day Emergency Department Visits and Readmissions in Adults After Tracheostomy

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 2, April 2026.
ABSTRACT Objective To quantify 30‐day emergency department (ED) visits and hospital readmissions post‐tracheostomy—distinguishing between tracheostomy and non‐tracheostomy‐related causes—and to identify revisit risk factors. Methods Retrospective cohort study of adult patients undergoing all‐cause tracheostomy within the system between April 1, 2018 ...

Machine Learning‐Based Risk‐Adjusted CUSUM Control Chart for Monitoring Readmission Rate Following PTBD Catheter Placement

Quality and Reliability Engineering International, Volume 42, Issue 3, Page 933-949, April 2026.
ABSTRACT Percutaneous transhepatic biliary drainage (PTBD) catheter placement is known to have a high readmission rate. This work focuses on monitoring the change in readmission rate after a new clinical paradigm for post‐procedural care is implemented for the PTBD procedures.
