Background:
Guided
self-management is
an important
component of asthma
care. Most trials
have evaluated
paper-based
strategies. The
effectiveness of new
communication
technologies remains
uncertain.
Objectives:
To compare the
feasibility and
clinical outcomes of
a standard
paper-based asthma
self-management
strategy with
web-based
strategies.
Methods: In a
crossover trial, 21
patients using
inhaled
corticosteroids and
long-acting
ß2-agonists (mean
[SD] age 29 [10]
years) were randomly
assigned to use a
sequence of
web-based and
paper-based diary
and action plan.
Quality of life,
asthma control, lung
function, and airway
inflammation were
assessed using the
Asthma Life Quality
Questionnaire (ALQ),
Asthma Control
Questionnaire
(ACQ-5), Mini Asthma
Quality of Life
Questionnaire (Mini
AQLQ), and office
spirometry. The
ratio of forced
expiratory volume in
the first second of
expiration (FEV1) to
peak expiratory fl
ow (PEF) rate
(PiKo-1) and
fraction of exhaled
nitric oxide (FENO)
were monitored. The
main clinical
outcomes were asthma
control and FENO.
Quality of data and
adherence to
monitoring tools
were the main
process outcomes.
Results:
Significant
improvements were
observed in the AQL
and ACQ scores,
although lung
function did not
change. FENO was
significantly
reduced only after a
web-based strategy
but a significant
period effect
occurred (P=.006).
There were no
differences in
clinical outcomes
between web-based
and paper-based
management. No
intervention-related
adverse effects were
observed. Adherence
seemed higher with
the paper-based
strategy (P<.001).
However, paper data
were unreliable when
compared to
automatic daily
electronic FEV1/PEF
records. Twelve
patients were very
interested in
continuing
self-management with
the web-based
approach compared
with 2 in using
paper tools
(P=.002).
Conclusions:
Web-based management
was feasible, safe,
and preferred by
patients. Short-term
outcomes were at
least as good, and
data quality was
improved.
Key words:
Asthma. Crossover.
Internet.
Self-management.
