This study aimed to examine the interrater agreement of Critical-Care Pain Observation Tool-Neuro (CPOT-Neuro) scores as a newly developed tool for pain assessment in patients with critical illness and brain injury between raters using two methods of rating (bedside versus video) during standard care procedures (i.e., non-invasive blood pressure and turning). The bedside raters were research staff, and the two video raters had different backgrounds (health and non-health disciplines). Raters received standardized 45 min training by the principal investigator. Video recordings of 56 patient participants with a brain injury at different levels of consciousness were included. Interrater agreement was supported with an Intraclass Correlation Coefficient (ICC) > 0.65 for all pairs of raters and for each procedure. Interrater agreement was highest during turning in the conscious group, with ICCs ranging from 0.79 to 0.90. The use of video recordings was challenging for the observation of some behaviors (i.e., tearing, face flushing), which were influenced by factors such as lighting and the angle of the camera. Ventilator alarms were also challenging to distinguish from other sources for the video rater from a non-health discipline. Following standardized training, video technology was useful in achieving an acceptable interrater agreement of CPOT-Neuro scores between bedside and video raters for research purposes.

Background: The Modified Rush Video‐Based Tic Rating Scale (MRVS) is the most widely used video‐based scale for assessing tic severity in patients with Tourette syndrome (TS). However, shortcomings of the MRVS, including a lack of clear instructions, a time‐consuming recording procedure, and weak correlations with the gold standard for tic assessment, the Yale Global Tic Severity Scale‐Total Tic Score (YGTSS‐TTS), limits its use in research settings, although video assessments are generally considered objective, reliable, and time‐saving measurements. Objectives: We aimed to revise the MRVS (MRVS‐R) to simplify and standardize the assessment procedure and improve the correlation with the YGTSS‐TTS. Methods: We used 102 videos of patients with TS or persistent motor tic disorder filmed according to the MRVS. We compared the tic frequency assessed by MRVS with frequencies according to MRVS‐R based on a 5‐min (instead of a 10‐min) video to investigate whether reducing the recording time leads to significant changes. In addition, we adapted the MRVS to the YGTSS and defined new anchor values for motor and phonic tic frequency based on frequency distributions as assessed in our sample. Finally, we compared the MRVS‐R and MRVS regarding psychometric properties and correlation with the YGTSS‐TTS. Results: Cutting video recording time in half did not significantly affect assessments of motor and phonic tic frequencies. Psychometric properties were acceptable. Most important, proposed revisions of the MRVS improved correlation with the YGTSS‐TTS. Conclusions: The MRVS‐R is a simplified version of the MRVS with comparable psychometric qualities, but higher correlations with the YGTSS‐TTS. [ABSTRACT FROM AUTHOR]

This document is a reply to a letter to the editor regarding the Rush Video-Based Tic Rating Scale-Revised (MRVS-R). The authors respond to critiques and suggestions made by Becker et al. They explain that they do not favor adding explicit instructions to patients not to suppress their tics, as it may draw attention to the tics. They also clarify that the instructions for determining blink rate do not suppress eye tics. The authors address other concerns raised by Becker et al and emphasize the importance of a practical and standardized protocol for assessing tics. [Extracted from the article]
