OBJECTIVE
To assess
the impact of lifetime continuous care within the John Hunter Hospital
cystic fibrosis (CF) clinics on growth and lung function.
DESIGN
A cross
sectional survey of variables affecting nutritional status in CF was
undertaken for 1993 and 1997. Data were retrieved from medical records
and grouped into 5 year age bands.
MAIN OUTCOME
MEASURES
Change in height z-score, weight centile,
and forced expiratory volume in one second (FEV1) between
patient cohorts receiving specialised care for different lengths of time.
RESULTS
Improved mean
height z-score (
0.880 v
0.047) and
weight centile (28.3% v 48.1%) for the
10-15 year age group in 1997, who had received continuous lifetime
care within the clinic, compared with the same age group in 1993, for
whom continuous medical care started at an older age. There was no
corresponding improvement in FEV1, as an indicator of lung
function, in this group (81.6% predicted v
89.5% predicted).
CONCLUSIONS
This study
suggests that lifetime continuous care within a specialised CF centre
is associated with improved growth but not improved lung function.
