Atypical pressure ulcers (APU) occur in 21% of all pressure ulcers, often linked to spasticity, medical devices, or bony deformities. Early recognition and multidisciplinary team intervention are key for healing and prevention.
Area of Science:
- Wound Care
- Dermatology
- Rehabilitation Medicine
Background:
- Atypical pressure ulcers (APU) are distinct from common pressure ulcers (PU) due to unique locations and causes, yet their occurrence and characteristics are often overlooked.
- Understanding APU is crucial for effective patient management and preventing complications.
Purpose of the Study:
- To analyze the incidence of atypical pressure ulcers (APU).
- To investigate the circumstances contributing to APU causation.
- To highlight the importance of a multidisciplinary team approach for APU prevention and treatment.
Main Methods:
- A 3.5-year prospective cohort study involving 174 patients.
- Implementation of weekly staff meetings focused on wound assessment and multidisciplinary patient reviews.
- Systematic documentation of wound location, etiology, and treatment outcomes.
Main Results:
- Atypical pressure ulcers (APU) accounted for 21% of all acquired pressure ulcers (PU) over the study period.
- Severe spasticity (knees, elbows, palms), medical devices (neck, penis, nostrils), and bony deformities (shoulder blades, spine) were the primary causes.
- Wounds associated with severe spasticity presented the greatest treatment challenges.
Conclusions:
- Atypical pressure ulcers (APU) are a significant subset of pressure ulcers requiring specific recognition.
- Effective identification, prevention, and treatment of APU are achievable.
- A multidisciplinary team plays a pivotal role in managing atypical pressure ulcers.
