研究目的
To describe the initial experiences with an alternative light source (ALS) for enhancing visual inspection and early detection of deep tissue pressure injury (DTPI) in clinical cases.
研究成果
The use of an alternative light source (ALS) enhanced visual inspection of skin, revealing nuances not visible to the unaided eye, such as darker and more distinct areas of compromised tissue. This allowed for more accurate identification of deep tissue pressure injuries and adjustments in care plans. However, additional research is required to confirm its efficacy in early detection and prevention of pressure injuries.
研究不足
The study is limited by its small sample size of only three cases, which may not be representative of broader populations. The ALS technology's effectiveness for early DTPI detection was not definitively proven, and further research is needed. Additionally, in one case, it was unclear whether observed hyperpigmentation was due to pressure injury or natural skin variation, highlighting potential issues in interpretation.
1：Experimental Design and Method Selection:
A multiple case series design was used to describe the application of ALS technology in clinical skin assessment. The ALS technique, originally developed for forensic investigation, was employed to enhance visual inspection by utilizing light interactions such as fluorescence, absorption, and oblique lighting.
2：Sample Selection and Data Sources:
Three cases were selected from patients in an acute care facility. Participants were African American adults with various skin conditions, including hyperpigmentation and pressure injuries. Informed consent was obtained from each participant.
3：List of Experimental Equipment and Materials:
An alternative light source (ALS) device was used, though specific model and brand are not detailed in the paper. Other materials included standard wound care products such as silicone-based barrier creams and specialty mattresses.
4：Experimental Procedures and Operational Workflow:
Certified wound, ostomy, and continence nurses (CWOCNs) performed visual skin assessments under ambient lighting and then used the ALS to illuminate the skin areas. Observations were made on how compromised skin appeared under ALS compared to unaided inspection. Care plans were adjusted based on findings.
5：Data Analysis Methods:
Qualitative analysis was conducted based on visual observations and clinical judgments. No statistical analysis was performed as it was a descriptive case series.
