Abstract
Background: Cystic fibrosis is the most common incurable hereditary disease in the US. Persistent respiratory infection is the leading cause of morbidity and mortality in cystic fibrosis patients. Objective: This study aimed to review the literature on economic and quality of life outcomes and treatment compliance associated with antibiotic therapies for cystic fibrosis patients. Methods: A systematic literature review was conducted using keyword searches of the MEDLINE® database and selected conference abstracts. The review covered studies published between January 1990 and May 2007. Results/conclusions: Evidence suggests that inhaled tobramycin, a key chronic suppressive therapy, can reduce other healthcare costs. The main determinants of the cost of care include disease severity and respiratory infection. Costs vary widely by country. There is evidence that inhaled tobramycin and oral azithromycin improve quality of life and that treatment setting and patient convenience may also impact on quality of life. Antibiotic treatment compliance varied significantly and depended on the method of measurement, with more subjective measures tending to be higher. This review concludes by offering directions for future research.
