Scale for Total Assisted-Patients (STAP): Development, Reliability, Validity, and Prediction of Pressure Sore Risk

Abstract

Objective: To develop the scale can evaluate change of condition of Total-Assisted Patients, and to explore its validity, reliability, and usefulness for predicting pressure sore risk.
Methods: We first developed the Scale for Total-Assisted Patients (STAP). The analysis was conducted as follows: the correlation and Mann-Whitney U Test of STAP score and FIM score, change of STAP score for 3 months and factor analysis, explore the reliability by intraclass correlation (ICC) and kappa, logistic regression was used to calculate the odds ratio (OR) with 95% confidence interval (CI) for assess the pressure sore risk.
Results: STAP was more suitable for total-assisted patients than FIM, 63.7% of patients with FIM 18 were observed STAP score change. Three factor were extracted from the factor analysis, “Limb range of motion”, “Amount of assistance with postural change”, “Consciousness”. Inter-rater reliability was ICC = 0.86, kappa = 0.95~0.99, OR = 0.83 (95% CI: 0.68–0.99, p=0.04).
Conclusion: STAP was more sensitive to change of condition of total-assisted patients than FIM, and STAP has high inter-rater reliability. Moreover STAP total score may be useful for predicting pressure sore risk.
