TL;DR: Clinicians and researchers involved in MDI evaluation and education should be trained to achieve consistency and include at least two evaluators to assess MDI technique or take other measures to show and report reliability.

TL;DR: To assess the intra‐ and inter‐rater reliability of different ultrasound measures of the lumbar multifidus muscle in subjects with and without chronic low back pain, 3 different ways to enhance reliability are tested by testing different tasks, using a template, and averaging trials within or between days.
Abstract: Objective To (1) assess the intra- and inter-rater reliability of different ultrasound (US) measures of the lumbar multifidus muscle in subjects with and without chronic low back pain and (2) test 3 different ways to enhance reliability, that is, by testing different tasks, using a template, and averaging trials within or between days. Design Cross-sectional repeated-measures design. Setting Laboratory setting. Patients Fifteen subjects with chronic low back pain and 15 control subjects. Methods Subjects (n = 30) performed contralateral arm lifting and contralateral leg lifting while in the prone position. Two 7-second videos of the lumbar multifidus (from rest to contraction) were collected with and without a template (transparency) to reposition the transducer on the skin. One of the two raters repeated the testing 7 to 14 days later to assess intrarater reliability in addition to inter-rater reliability. Reliability was assessed with the generalizability theory as a framework. Main outcome measurements US imaging measures of the lumbar multifidus thickness were obtained in patients at rest and during standardized contractions (hereafter called primary measures) at 2 vertebral levels and on both sides. These primary measures were used to calculate different, potentially useful US parameters (hereafter called derived measures). Results Intrarater reliability was better than inter-rater reliability, and primary measures were more reliable than derived measures. The tasks investigated showed comparable reliability results, and the use of the transducer position template was not effective to increase reliability. Averaging the measures of 3 images increased reliability substantially. Conclusions Optimal reliability requires the use of a single rater and the averaging of at least 3 images per visit. In these conditions, primary measures reach acceptable levels of reliability, which was more difficult to achieve for most derived measures. Arm or leg lifting tasks showed similar reliability, and thus the arm-lifting task is recommended for comparisons with previous studies. The use of a transducer position template is not recommended.

TL;DR: The I-4L triage model shows a good inter-rater and intrarater reliability for rating triage acuity and for accuracy in patient admission and prediction of a reference standard's triage code.
Abstract: Objectives To measure the reliability and predictive validity of a four-level triage system (I-4L). Methods This observational study was conducted in an urban hospital. Five nurses were randomly selected to assign a triage level to 246 paper scenarios, using the I-4L model. The I-4L model is a four-level triage system: urgency category (UC) 1 requires immediate response; UCs 2, 3 and 4 require assessment within 20, 60 and 120 min, respectively. Weighted κ statistics were used to measure the inter-rater and intrarater reliability of the triage tool and the validity of the model was assessed based on the accuracy in predicting admission and in predicting a reference standard9s triage code. Results The I-4L model9s inter-rater reliability was κ=0.73 (95% CI 0.67 to 0.79), and the intrarater reliability was κ=0.82 (95% CI 0.67 to 0.96). Its accuracy of triage rating for admission and for prediction of a reference standard9s triage code was good: 79% (95% CI 73% to 86%) and 93% (95% CI 89% to 96%), respectively. The percentages of patients admitted per triage level using the I-4L model was: 100% UC 1; 42% UC 2; 6% UC 3; and 2% UC 4. Conclusions The I-4L triage model shows a good inter-rater and intrarater reliability for rating triage acuity and for accuracy in patient admission and prediction of a reference standard9s triage code.
