Study Notes
Decubitus Ulcers Overview
- Also known as bed sores, rooted in Latin meaning "lying down."
- Frequently occur at bony joints or areas with high pressure.
Affected Populations
- Common in chronically debilitated individuals, diabetics, and elderly adults (aged over 70).
- Includes diabetic foot infections (DFIs).
Microbial Characteristics
- Mild cases are usually monomicrobial.
- More severe sores can be polymicrobial, affecting up to 60% of hospitalized patients.
Complications
- Untreated decubitus ulcers and DFIs can lead to osteomyelitis.
Pressure Sore Staging
- Stages indicate severity and depth of infection:
- Stage 1: Affects both dermis and epidermis (monomicrobial).
- Stage 2: Extends into subcutaneous skin tissue and fat.
- Stage 3: Involves muscle and fascia.
- Stage 4: Affects bone (polymicrobial).
Treatment Approaches
- Sore wound cleansing with possible debridement recommended for treatment.
- Mild cases: Deep culture biopsy or needle aspiration at wound base for antimicrobial susceptibility testing (AST).
- Moderate cases: Require antibiotics alongside culture biopsy from wound base.
- Severe cases: Also need antibiotics in addition to bone culture biopsy for AST.
