Background: Lung function is assessed in multiple ways following transplantation. Understanding how objective measures align with how a patient feels is an important factor to obtain a comprehensive picture of a lung transplant recipient’s (LTR) health status. In viewing how well objective measures and self-reported perceived measures are as predictors of one another, and how psychological distress impacts this relationship, we can view respiratory health from a bigger picture. The aim of this essay is to examine this relationship to better understand both clinical and subclinical lung function. missing mention of psychological distress
Methods: Secondary analysis of baseline data from a sample of 65 LTRs enrolled in the LTGO study (R01NR017196-01A1) including an objective measure of lung function (Pulmonary Function Tests (PFTs), perceived measure of lung function (SGRQ), and symptoms of psychological distress (SCL-90 Short form). Pearson’s correlation and linear regression were used to identify the relationship between objective and perceived measures of lung function. One-sided paired T-tests were performed to analyze the impact of psychological distress on each measure of lung function.
Results: Among the 65 participants, the mean FEV1 % was 77.58 (SD=23.23), SGRQ symptom score was 38.75 (SD=19.82) and SGRQ total score 31.18 (SD=19.82). There were 26 participants (40%) with evidence of clinically significant psychological distress. The relationship between objective and perceived lung function had a weak negative correlation (r=-0.1473, p-0.32), yet the inverse, objective lung function is statistically significant when adjusting for confounders (p=0.007). When analyzed individually with symptoms of psychological distress, objective measures of lung function were not statistically significant based on distress status (p=0.544) while perceived lung function was statistically significant (p=0.0005).
Conclusion: A difference was found between the objective and perceived measures of lung function. Participants with significant psychological distress were more likely to report higher SGRQ symptom and total scores resulting in poorly perceived respiratory health and quality of life. Understanding how each of these factors are involved has direct public health relevance by viewing mental and physical health in unison to improve overall health and well-being for an at-risk population.
