People with CF treated with IV antibiotics for a pulmonary exacerbation (PEx) frequently fail to recover to baseline FEV1. The long-term impact of these events has not been studied. To determine if a patient’s spirometric recovery after a PEx is associated with time to next PEx within 1 year, the spirometric recovery after the next PEx, and/or the number of PEx episodes in the next 3 years. We used data from the CF Foundation Patient Registry from 2004–2011. We randomly selected one PEx per patient that met inclusion/exclusion criteria. Patients were defined as Non-Responders if their best FEV1 (in liters) recorded in the 3 months after the PEx was <90% of the best FEV1 (in liters) in the 6 months before the PEx. We compared Responders and Non-Responders using multivariable regression models. We randomly chose 13,954 PEx episodes that met inclusion/exclusion criteria. 2,762 (19.8%) patients were classified as Non-Responders. Non-Responders had a shorter median time to the next PEx, 235 (95% CI 218, 252) days, versus >365 days for Responders. Thirty-four percent of Non-Responders at the initial PEx were also Non-Reponders at the next PEx, versus 20% of Responders at the initial PEx. Non-Responders had more PEx episodes over the next 3 years, 4.99 (95% CI 4.84, 5.13), than Responders, 3.46 (95% CI 3.41, 3.51). Poor recovery after a PEx is associated with a shorter time to the next PEx, increased risk of poor recovery at a second PEx, and more frequent subsequent PEx treatments.
