Objectives:
Quantification of academic productivity relies on bibliometric measurements, such as the Hirsch index (h-index). The National Institutes of Health (NIH) recently developed the relative citation ratio (RCR), an article-level, citation-driven metric that compares researchers with others within their respective fields. Our study is the first to compare the usage of RCR in academic otolaryngology.
Study Design:
Retrospective Database Review.
Methods:
Academic otolaryngology residency programs were identified using the 2022 Fellowship and Residency Electronic Interactive Database. Demographic and training data were collected for surgeons using institutional websites. RCR was calculated using the NIH iCite tool, and h-index was calculated using Scopus. Mean RCR (m-RCR) is the average score of the author's articles. Weighted RCR (w-RCR) is the sum of all article scores. These derivatives are a measure of impact and output, respectively. The career duration of a physician was categorized into the following cohorts: 0-10, 11-20, 21-30, and 31+ years.
Results:
A total of 1949 academic otolaryngologists were identified. Men had higher h-indices and w-RCRs than women (both p less than 0.001). m-RCR was not different between genders (p = 0.083). There was a difference in h-index and w-RCR (both p less than 0.001) among the career duration cohorts, but there was no difference in m-RCR among the cohorts (p = 0.416). The faculty rank professor was the greatest for all metrics (p < 0.001).
Conclusion:
Critics of the h-index argue that it is reflective of the time a researcher has spent in the field, instead of impact. The RCR may reduce historic bias against women and younger otolaryngologists.

01:20Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
