Background: This retrospective audit was undertaken to compare the efficacy of home intravenous (i.v.) antibiotic therapy, hospital i.v. antibiotic therapy and a combination of these 2 approaches, as determined by spirometric measures of lung function in cystic fibrosis (CF) patients, each with an acute respiratory exacerbation.
Methods: Pulmonary function, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), forced expiratory flow rate between 25 per cent and 75 per cent of vital capacity (FEF25-75), and peak expiratory flow rate (PEFR) were compared between groups at the beginning and at the end of an IV antibiotic course.
Results: Treatment of exacerbations resulted in a significant improvement (p < 0.05) in lung function irrespective of where patients were treated. The percentage improvement in FEV1, FVC, and FEF25-75, were significantly greater in patients treated in hospital compared to those who had home i.v. treatment (p < 0.05).
Conclusion: Hospital i.v. antibiotic therapy resulted in greater improvements in FEV1, FVC and FEF25-75 than home i.v. antibiotic therapy in CF patients with an acute respiratory infection.
