Does a combination of fractional order shape index ratio and fuzzy colour relation analysis detect venous needle dislodgement during haemodialysis?
A novel model combining fractional order shape index ratio and fuzzy colour relation analysis may be useful for detecting life-threatening venous needle dislodgement during haemodialysis.
May enable automated detection of venous needle dislodgement in haemodialysis; leaves open prospective validation before clinical use.
Venous needle dislodgement (VND) is a life-threatening complication during haemodialysis (HD) treatment. When VND occurs, it only takes a few minutes for blood loss in an adult patient. According to the ANNA (American Nephrology Nurses' Association) VND survey reports, VND is a concerning issue for the nephrology nurses/staff and patients. To ensure HD care and an effective treatment environment, this Letter proposes a combination of fractional order shape index ratio (SIR) and fuzzy colour relation analysis (CRA) to detect VND. If the venous needle drops out, clinical examinations show that both heart pulses and pressure wave variations have a low correlation at the venous anatomic site. Therefore, fractional order SIR is used to quantify the differences in transverse vibration pressures (TVPs) between the normal condition and meter reading. Linear regression shows that the fractional order SIR has a high correlation with the TVP variation. Fuzzy CRA is designed in a simple and visual message manner to identify the risk levels. A worst-case study demonstrated that the proposed model can be used for VND detection in clinical applications.

Lin et al. (2015) conducted a letter in Venous needle dislodgement during haemodialysis. Fractional order shape index ratio and fuzzy colour relation analysis was evaluated on Detection of venous needle dislodgement. A proposed model combining fractional order shape index ratio and fuzzy colour relation analysis demonstrated the ability to detect venous needle dislodgement during haemodialysis in a worst-case study.
