CLD was defined as patients with known diagnosis of asthma, COPD, bronchiectasis, OSA, ILD,PE, lung cancer and pulmonary hypertension.Methods: We reviewed notes for the patients with Influenza (A&B) positive swab results between October 2017 till April 2018. Patients were categorised according to age.Results: A total of 668 patients were identified with influenza A&B, 218(32.6%) had CLD. The difference in hospital stay for those with and without CLD was 11.88 vs 12.5 days (p=0.29).27 patients were admission to ICU. 3.2%(n=7) of patients with CLD were admitted to ICU, 4.4%(n=20) without CLD were admitted to ICU (p=0.3). There was a 13.3% mortality rate in patients with CLD, compared to a 11% mortality rate for non-CLD. The median length of stay in those dying was 15.7 days for CLD and 12.6 days for non-CLD. The readmission rate at 30 days was 15.8% for CLD, and 9.5% for non-CLD patients.Conclusion: Influenza with CLD is associated with longer length of stay in under 50’s compared to non-CLD. Readmission and mortality were higher in CLD patients.View this table:Table 1.
