Hospital-Acquired Pressure Ulcers and Long-Term Motor Score Recovery in Patients With Acute Cervical Spinal Cord...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Clinical Research

Background:

• Pressure ulcers (PUs) are common complications following spinal cord injury (SCI).
• PUs can elevate systemic inflammation and impede neurological recovery.
• The impact of PUs acquired during initial hospitalization on long-term SCI outcomes is not fully understood.

Purpose of the Study:

• To investigate the association between PUs acquired during initial hospitalization and long-term neurological, functional, and survival outcomes after SCI.
• To determine if PUs represent a modifiable risk factor influencing recovery after SCI.

Main Methods:

• A multicenter cohort study utilizing data from the SCI Model Systems (SCIMS) Database.
• Inclusion of patients with acute traumatic cervical SCI and motor impairment (ASIA impairment scale A, B, C) from 1996-2006.
• Analysis of motor recovery (ASIA score) and functional independence (FIM score) at 1 year, and mortality up to 10 years, using mixed-effects models and Cox regression.

Main Results:

• Of 1282 SCI patients, 45.7% acquired PUs during initial hospitalization.
• PUs were associated with significantly impaired motor recovery (-9.1 ASIA points) and functional independence (-8.3 FIM points) at 1 year post-SCI.
• PUs were identified as a risk marker for increased mortality up to 10 years (HR 1.41).

Conclusions:

• PUs acquired during initial hospitalization are independently associated with poorer long-term neurofunctional outcomes after SCI.
• PUs represent a modifiable factor contributing to worse long-term disability and elevated mortality in SCI survivors.
• Early management and prevention of PUs are crucial for optimizing recovery and survival post-SCI.
