Bates-Jensen Wound Assessment Tool
Also known as: BJWAT, Bates-Jensen Assessment Tool, Pressure Ulcer Scale for Healing
The Bates-Jensen Wound Assessment Tool (BJWAT), originally developed as the Pressure Sore Status Tool, is a comprehensive instrument for objectively assessing pressure ulcer characteristics and monitoring healing progress. Created by Barbara M. Bates-Jensen, the tool evaluates 13 distinct wound dimensions including size, depth, tissue type, and exudate. It provides quantitative assessment of wound severity and is useful for tracking changes over time and evaluating treatment effectiveness.
Key highlights
- Comprehensive assessment of multiple wound dimensions rather than single measurement
- High validity and reliability for assessing and tracking pressure ulcer healing
- Provides objective scoring that reduces subjective interpretation
- Sensitive to both improvements and deterioration in wound status
- Useful for research, outcome measurement, and treatment evaluation
- Facilitates interdisciplinary communication regarding wound status

When to use it
Apply the BJWAT when a pressure ulcer has been identified to establish baseline severity and create a standardized monitoring system. Assess weekly or more frequently if changes are occurring. Use when communicating wound status to other healthcare providers, documenting for reimbursement purposes, and evaluating treatment response. Continue assessment throughout the ulcer's trajectory until healed.
Strengths & limitations
- Comprehensive assessment of multiple wound dimensions rather than single measurement
- High validity and reliability for assessing and tracking pressure ulcer healing
- Provides objective scoring that reduces subjective interpretation
- Sensitive to both improvements and deterioration in wound status
- Useful for research, outcome measurement, and treatment evaluation
- Facilitates interdisciplinary communication regarding wound status
- Time-consuming to complete, requiring 10-15 minutes of assessment and documentation
- Requires training and experience for consistent and accurate scoring of subjective items
- Does not account for all wound assessment considerations (e.g., pain, infection bioburden)
- Scoring subjective dimensions may vary between assessors without standardized training
- Difficult to implement in settings with limited time or resources for detailed assessment

Frequently asked
How often should the BJWAT be completed?
Most commonly weekly, though frequency may increase to every 2-3 days if the wound is changing rapidly or treatment is being adjusted. Frequency should be consistent to enable meaningful trend analysis.
Who should complete the BJWAT assessment?
Any qualified clinician can use the BJWAT, though consistency in assessor is preferred. Nurses, wound care specialists, and physicians are common users. Training ensures accurate and reliable scoring.
What does a BJWAT score indicate about healing?
Lower scores indicate better healing and less severe wounds. Generally, scores below 12-15 suggest significant healing. Increasing scores indicate deterioration. Serial scoring tracks the trajectory of healing or deterioration.
Can the BJWAT be used for non-pressure wounds?
While designed for pressure ulcers, the BJWAT has been adapted and used for assessing other chronic wounds including diabetic foot ulcers, venous ulcers, and surgical wounds. However, some dimensions may be more relevant than others depending on wound type.
