Insights
The Procedural Restraint Intensity in Children (PRIC) scale was metrologically validated for measuring restraint intensity during pediatric procedures. This new scale shows high reliability and validity, offering a standardized tool for clinical use.
Area of Science:
- Pediatric healthcare
- Clinical assessment tools
- Patient safety
Background:
- Restraint is frequently employed during pediatric procedures.
- A validated scale to quantify restraint intensity was lacking.
- This study addresses the need for a reliable measurement tool.
Purpose of the Study:
- To validate the metrological criteria of the Procedural Restraint Intensity in Children (PRIC) scale.
- To assess the reliability and construct validity of the PRIC scale.
- To establish a standardized method for measuring restraint intensity in children.
Main Methods:
- Seven healthcare professionals evaluated 20 videos of pediatric procedures.
- Inter-rater and test-retest reliability were assessed using intra-class correlation coefficients.
- Construct validity was determined by correlating the PRIC scale with a numerical rating scale.
Main Results:
- High inter-rater reliability (0.98) and test-retest reliability (0.98) were observed.
- A strong positive correlation (Spearman coefficient 0.93) was found between the PRIC scale and a numerical rating scale.
- 140 measurements were completed, supporting the scale's robustness.
Conclusions:
- The PRIC scale demonstrated metrological validity for measuring restraint intensity in children.
- While limitations exist due to the absence of a gold standard and experimental conditions, the PRIC scale is the first of its kind with metrological validation.
- Future research will focus on validating the PRIC scale in real-world clinical settings.
Purpose:
Restraint is often used when administering procedures to children. However, no metrologically scale to measure the restraint intensity had yet been validated. This study validated the metrological criteria of a scale measuring the restraint intensity, Procedural Restraint Intensity in Children (PRIC), used during procedures in children.
Design And Methods:
The PRIC scale performance was measured by a group of 7 health professionals working in a children's hospital, by watching 20 videos of health care procedures. This group included 2 physicians, 1 pediatric resident, and 4 nurses. The intra-class correlation coefficients were calculated to evaluate the inter-rater and test-retest reliability and the construct validity with the correlation between PRIC scale and a numerical rating scale.
Results:
One hundred and forty measurements were made. Inter-rater and test-retest correlation coefficients were 0.98 and 0.98, respectively. The 2 scales were positively correlated with a Spearman coefficient of 0.93.
Conclusions:
This study validated the Procedural Restraint Intensity in Children (PRIC) scale in metrological terms with some limitation. However, there is not gold standard scale to precisely validate the reliability of this tool and this study has been conducted in "experimental" conditions. Nevertheless, this is the first scale measuring the intensity of physical restraint with a metrological validation. The next step will be to validate it in real clinical situations.
