Idiopathic Pulmonary Fibrosis, Progressive Pulmonary Fibrosis
Conditions
Brief summary
This is a cross-sectional study that will be conducted across Japan using an online patient-reported outcome questionnaire. This study tries to find out the attitudes toward and experiences of the emotional and/or social impact of side effects associated with antifibrotic (AF) treatment among Japanese patients with Idiopathic Pulmonary Fibrosis (IPF)/Progressive Pulmonary Fibrosis (PPF), and how are these attitudes associated with patients' individual characteristics.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean (95% CI) scores for the PESaM side effects sub-domain in the overall population | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The score of patient experiences and satisfaction with medications (PESaM) side effects sub-domain ranges from 0-4, with higher scores indicating a lower burden of side effects and a more positive (favorable) patient experience. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between PESaM side effects sub-domain and SDM-Q-9 | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The score of of PESaM side effects sub-domain ranges from 0-4, with higher scores indicating a lower burden of side effects and a more positive (favorable) patient experience. The 9-Item SDM-Q-9 score is derived as a sum of the nine items, each rated on a 6-point Likert scale from 0 (completely disagree) to 5 (completely agree) and it ranges from 0 to 45. A higher score indicates a greater degree of patient involvement in the shared decision-making process (reflecting better shared decision-making). |
| Descriptive statistics of patient background in high- and low-score groups for the PESaM side effects sub-domain | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The score of PESaM side effects sub-domain ranges from 0-4, with higher scores indicating a lower burden of side effects and a more positive (favorable) patient experience. The following descriptive statistics will be reported: * Sex * Age |
| Clinical characteristics in high- and low-score groups for the PESaM side effects sub-domain | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The score of PESaM side effects sub-domain ranges from 0-4, with higher scores indicating a lower burden of side effects and a more positive (favorable) patient experience. The following clinical characteristics will be reported: * Lung diseases group * AF treatment in use * Disease duration * Severity/use of oxygen therapy |
| Mean (95% CI) scores for the PESaM side effects sub-domain by IPF/PPF group, and by AF treatment | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The score of of PESaM side effects sub-domain ranges from 0-4, with higher scores indicating a lower burden of side effects and a more positive (favorable) patient experience. |
| Mean (95% CI) scores for the EQ-5D-5L | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The quality of life (Qol) 5 dimensions 5-level (EQ-5D-5L) index score ranges from less than 0 (states valued as worse than death, with a minimum of -0.025 based on the Japanese tariff) to 1 (perfect health). Higher scores indicate a better health-related quality of life. |
| Mean (95% CI) scores for the SDM-Q-9 | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The 9-Item Shared Decision-Making Questionnaire (SDM-Q-9) score is derived as a sum of the nine items, each rated on a 6-point Likert scale from 0 (completely disagree) to 5 (completely agree) and it ranges from 0 to 45. A higher score indicates a greater degree of patient involvement in the shared decision-making process (reflecting better shared decision-making). |
| Validity (correlation with EQ-5D-5L) of PESaM side effects sub-domain | Assessed once at survey completion (approximately 20 minutes after survey initiation). | The score of of PESaM side effects sub-domain ranges from 0-4, with higher scores indicating a lower burden of side effects and a more positive (favorable) patient experience. EQ-5D-5L index score ranges from less than 0 (states valued as worse than death, with a minimum of -0.025 based on the Japanese tariff) to 1 (perfect health). Higher scores indicate a better health-related quality of life. |
| Reliability (Cronbach's α) of PESaM side effects sub-domain | Assessed once at survey completion (approximately 20 minutes after survey initiation). | To evaluate the reliability of the PESaM side effects sub-domain, Cronbach's alpha will be calculated. |
