| Summary: | Introduction: Delay in turnaround time (TAT) of blood delivery
for transfusion is an important administrative problem in
hospitals. Time and motion study for a definite root cause
analysis (RCA) is valuable to identify the root causes of
problems in the operating events.
Aim: The study was undertaken to observe TAT and the
causes of increased TAT of blood delivery for transfusion to the
admitted patients on an emergency basis at hospital and to
formulate plans to rectify them.
Materials and Methods: This descriptive longitudinal study
was performed on 50 randomly selected admitted patients
requiring emergency blood transfusion during a period of
six months and were not assisted by volunteers. Another 50
control patients were incorporated, who were accompanied
by volunteers who assisted them in getting the blood. RCA of
the delays in TAT was done. Time intervals of TAT in the two
groups were compared by 2 tailed t-tests for equality of means.
The data was analysed using Epi-info 7 and SPSS version
16. A ‘p-value’ of less than 0.05 was taken to be statistically
significant.
Results: All the time intervals were high in the study group
in comparison to the control group and in most cases they
were statistically significant (p< 0.05) within a 95% confidence
interval of the difference. The maximum time needed in both
groups was in D7 (mean 89.70 and 83.50 minutes in cases
and controls respectively) i.e. the interval between the relative
reaching regional blood transfusion centre with blood sample
and donor (T7) and patient’s blood sample being processed for
grouping and cross matching (T8).
Conclusion: The study revealed that certain easy to implement
administrative steps would help to reduce the TAT significantly |
