Readability of patient-reported outcome measures for chronic rhinosinusitis and skull base diseases.

OBJECTIVE

Outcome measures in healthcare that presume a higher level of patient health and overall literacy may inadequately estimate the disease experiences of less-educated patients and further disadvantage them. Patient-Reported Outcome Measures (PROMs) are widely used communication tools for clinical practice and are often used to evaluate and guide management for chronic rhinosinusitis (CRS) and skull base diseases. However, their readability and subsequent incomprehensibility for patients have not been assessed. The aim of this study is to evaluate the readability of commonly used PROMs for these conditions and whether they meet recommended readability levels.

METHODS

Three readability measures, Gunning Fog, Simple Measure of Gobbledygook (SMOG), and FORCAST were used in the evaluation of commonly used PROMs for CRS and skull base disease. PROMs with sixth-grade readability level or lower were considered to meet health literacy experts' recommendations.

RESULTS

A total of 11 PROMs were reviewed (8 CRS, 3 skull base). Gunning Fog consistently estimated the easiest readability, whereas FORCAST the most difficult. One hundred percent of CRS and 67% of skull base PROMs were above National Institutes of Health and health literacy experts' recommended reading levels. PROMs developed more recently had easier readability.

CONCLUSION

PROMs are important clinical tools in otolaryngology that help guide management of disease for improved patient-centered care. Like many other fields of medicine, those used in otolaryngology are beyond recommended reading levels. Development of PROMs in the future should meet recommended readability levels to fully assess the disease experience of our patients.
