Cystic fibrosis mortality: registry data of cystic fibrosis

Area of Science:

• Medical research
• Genetics
• Public health

Background:

• Cystic Fibrosis Foundation has collected patient data since 1966 from over 100 U.S. centers.
• Cystic fibrosis is a severe autosomal recessive genetic disorder impacting multiple body systems.
• Disability and premature mortality are common complications of cystic fibrosis.

Purpose of the Study:

• To compare mortality data from recent years (1994-1995) with historical registry data (1966-1972).
• To analyze age-specific mortality trends in cystic fibrosis patients.
• To assess the impact of medical treatment improvements on patient survival.

Main Methods:

• Utilized data collected by the Cystic Fibrosis Foundation Registry.
• Compared observed mortality in 1994-1995 with expected mortality in the general U.S. population.
• Age-matched historical data (1966-1972) for comparative analysis.

Main Results:

• Excess mortality rates showed a significant decrease between the two study periods.
• Mortality reduction ranged from 96% at ages 0-1 to 52% at ages 20-25.
• Comparative mortality was presented in four detailed tables.

Conclusions:

• Marked decrease in excess mortality observed over the study period.
• Improvements in medical treatment are credited for the observed reduction in mortality.
• Positive trends indicate enhanced survival rates for cystic fibrosis patients.
