Background: Several reports have demonstrated the
usefulness of daily home spirometry for early detection of
graft rejection and opportunistic infections after lung
transplantation. Direct report of spirometry through the
Internet may improve patient care and result in better
preservation of lung function.
Methods: We retrospectively reviewed the spirometry of
16 patients for a period of six months after lung transplant.
Eight patients were followed by routine clinic visits and
bronchoscopy scheduled at regular intervals; the other eight
patients were followed by home spirometry and the results were
reported daily via modem to a central service (Datalog Inc.)
where the data were converted into a spreadsheet format and
reported to us via the World Wide Web for daily review.
Results: At 6 months post transplant the control group
had a mean FVC%, FEV1% and FEF35-75% of predicted of 60%; 46%;
and 27% respectively. The values for the group monitored with
daily spirometry were 81%, 80% and 80% respectively. The
percentage of change from the baseline at one month after
transplant for FVC%, FEV1%, and FEF25-75% was 32%, 19% and –6%
for the control group and 31%, 23% and 0% for the study group.
Conclusion: After six months post lung transplant there
was no difference in the improvement in the spirometry between
patients who were followed by regular pre-scheduled visits Vs
those followed with daily home spirometry via the Internet.
