Core Outcome Measures in Chronic Rhinosinusitis With Nasal Polyps: In Practice and Research

Assessment of chronic rhinosinusitis with nasal polyps: Development of the Nasal Polyp Patient Assessment Scoring Sheet tool

Background

Chronic rhinosinusitis (CRS) is a heterogeneous disorder with a wide range of validated subjective and objective assessment tools to assess disease severity. However, a comprehensive and easy-to-use tool that integrates these measures for determining disease severity and response to treatment is still obscure. The objective of this study was to develop a standardized assessment tool that facilitates diagnosis, uniform patient monitoring, and comparison of treatment outcomes between different centers both in routine clinical practice and in research.

Methods

To develop this tool, published literature on assessment tools was searched on various databases. A panel of 12 steering committee members conducted an advisory board meeting to review the findings. Specific outcome measures to be included in a comprehensive assessment tool and follow-up sheet were then collated following consensus approval from the panel. The tool was further validated for content and revised with expert recommendations to arrive at the finalized Nasal Polyp Patient Assessment Scoring Sheet (N-PASS) tool.

Results

The N-PASS tool was developed by integrating the subjective and objective measures for CRS assessment. Based on expert opinions, N-PASS was revised to be used as an easy-to-use guidance tool that captures patient-reported and physician-assessed components for comprehensively assessing disease status and response to treatment.

Conclusion

The N-PASS tool can be used to aid in the diagnosis and management of CRS cases with nasal polyps. The tool would also aid in improved monitoring of patients and pave the way for an international disease registry.

The Impact of Ambient and Wildfire Air Pollution on Rhinosinusitis and Olfactory Dysfunction

PURPOSE OF REVIEW

With increasing industrialization, exposure to ambient and wildfire air pollution is projected to increase, necessitating further research to elucidate the complex relationship between exposure and sinonasal disease. This review aims to summarize the role of ambient and wildfire air pollution in chronic rhinosinusitis (CRS) and olfactory dysfunction and provide a perspective on gaps in the literature.

RECENT FINDINGS

Based on an emerging body of evidence, exposure to ambient air pollutants is correlated with the development of chronic rhinosinusitis in healthy individuals and increased symptom severity in CRS patients. Studies have also found a robust relationship between long-term exposure to ambient air pollutants and olfactory dysfunction. Ambient air pollution exposure is increasingly recognized to impact the development and sequelae of sinonasal pathophysiology. Given the rising number of wildfire events and worsening impacts of climate change, further study of the impact of wildfire-related air pollution is a crucial emerging field.
