Development of Medical Device-Related Pressure Injury Risk Assessment Scale

This study aimed to develop a valid and reliable measurement tool to assess the risk of medical device-related pressure injuries (MDRPIs) in patients. A methodological design was employed to evaluate the validity and reliability of the Medical Device-Related Pressure Injury Risk Assessment Scale (MDRPI Scale).

The study was conducted with 200 patients who were undergoing care and treatment involving the use of medical devices. Data were collected using the Patient Descriptive Characteristics Form, the MDRPI Scale, and the Braden Risk Assessment Scale. Analyses focused on evaluating the MDRPI Scale's validity and reliability.

The content validity index of the MDRPI Scale was 0.87, and its Cronbach α coefficient was 0.73. The scale's items, which explained 47.063% of the total variance, were grouped under 2 factors: Factor 1-General Condition of the Patient, and Factor 2-Effect of the Medical Device on the Contact Area. The model fit indices obtained from the Confirmatory Factor Analysis (CFA) supported the 2-factor structure (χ 2 / df =2.091). No problematic items were identified within the final 8-item version of the scale.

This study presents the first comprehensive and systematic scale specifically developed to identify MDRPI risk and to evaluate the integrity of skin and mucosa in patients exposed to medical devices. The findings demonstrate that the MDRPI Scale, consisting of 8 items and 2 factors, is a valid and reliable tool for assessing the risk of MPRPIs in clinical settings.
