Primary Outcomes

Adherence Trajectories to Nintedanib Among Idiopathic Pulmonary Fibrosis (IPF) Patients

The number of IPF patients per adherence trajectories to nintedanib is presented. The first claim for nintedanib was used for defining the initiation date. For each 30-day month (12 months) following the nintedanib initiation date, the Proportions of Days Covered (PDC) were calculated as the sum of days with supply divided by 30, the monthly nintedanib proportion of days covered was then calculated. The twelve 30-days PDC values were used as outcomes in the Group-based trajectory model (GBTM), the probabilities that a given individual is in each of the latent clusters was calculated by the GBTM estimation procedure using the monthly binary PDC ≥ 0.8 indicators as outcomes. The reported types of trajectories to nintedanib were: * Highly adherent (PDC ≈ 0.9) * Medium adherent (PDC ≈ 0.4-0.6) - Gradual decliners (PDC bottoms out by month 11) * Intermediate decliners (PDC bottoms out by month 8) * Rapid decliners (PDC approaches zero by month 4)

Time frame: Up to 1 year

Secondary Outcomes
