Purpose:
The purpose of this study was to investigate whether voice-related patient-reported outcome measures (PROMs) developed and validated since 2011 meet the recommendation by health literacy experts that such materials be written at a fifth-to-sixth grade reading level.
Method:
A readability analysis of eight voice-related PROMs was conducted. Readability formulas utilized were the Coleman-Liau index, Flesch-Kincaid reading ease, FORCAST, simple measure of Gobbledygook index, and Gunning-Fog score.
Result:
Three-fourths of the PROMs exceeded the recommended fifth- to sixth-grade reading level.
Conclusion:
Although awareness of health literacy has grown, voice-related PROMs continue to be developed without full consideration of their reading grade level. Researchers should consider revising or developing PROMs with consideration to reading grade level as well as other features to enhance readability.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
Assessment 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:
Physical Assessment of the Respiratory Tract IV: Auscultation
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
Assessment 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.
Critical Guidelines for Assessing Ventilation:
Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
