Assessing Health Related Quality of Life in Hypersensitivity Pneumonitis

Weill Medical College of Cornell University60 enrolled

Overview

The objective of this study is to administer and validate a disease specific health related quality of life (HRQOL) survey for patients with Chronic Hypersensitivity Pneumonitis (CHP).

The objective of this study is to administer and validate a disease-specific health related quality of life (HRQOL) survey for patients with Chronic Hypersensitivity Pneumonitis (CHP). The survey items have been developed and revised from prior qualitative research with CHP patients. Potential participants will be recruited from WCMC, the Pulmonary Fibrosis Foundation (PFF) Registry and outside physician referral for the study. Participants will be asked to sign informed consent. At the initial visit participants will be asked to complete the survey and two additional PROs needed for concurrent validity testing. Participants will then be asked to complete the HRQOL survey under study a second time 2 weeks after the initial visit for test-re-test reliability testing. Pulmonary function testing and six minute walk test results will be collected. Pertinent demographic and clinical information will be collected from the patients and their medical records or registry data (if a PFF Registry participant). All information will be entered into a REDCap database for secure data management and storage. Psychometric testing will be performed on the overall survey instrument and the individual items in order to test validity and reliability. The goal is that the survey developed will be a reliable and valid measurement tool for use in both clinical practice and research settings.

Outcomes

Primary Outcomes

Validation of a health-related quality of life instrument for patients with Chronic Hypersensitivity Pneumonitis

The newly developed survey that is being validated consists of 42 items that assess the impact that Hypersensitivity Pneumonitis has on daily life for those who have the disease.

Time frame: Day 0

Validation of a health-related quality of life instrument for patients with Chronic Hypersensitivity Pneumonitis by administering the Short Form (SF-12) Survey

This survey will be used to assess the validity of the newly developed health-related quality of life instrument. This survey consists of 12 items. The average score for this survey has been calibrated to 50 with scores below 50 indicating a below average score and scores above 50 indicating an above average score.

Time frame: Day 0

Validation of a health-related quality of life instrument for patients with Chronic Hypersensitivity Pneumonitis by administering the King's Brief Interstitial Lung Disease Questionnaire

This survey will be used to assess the validity of the newly developed health-related quality of life instrument. This survey consists of 15 items and is scored from 0-100 with 100 indicating good health.

Time frame: Day 0

Change in Health-related Quality of Life Assessment Score

The newly developed survey will be administered again in 2 weeks following the first assessment.

Time frame: 2 weeks following Day 0
