Abstract
Purpose: To explore the measurement of a
scale of caesarean (C-section) risk factors and degree
of risk contribution in different health facilities and
to determine a suitable graphical representation (image)
of caesarean cases.
Methods: Based on seventeen indicators, a
composite index was computed for each respondent and
classified into three groups using Beta distribution of
first kind. For the analysis of contribution of risk
factors between private and public patients, principal
component analysis (PCA) was also used. An attempt was
made to visualise a suitable graphical representation of
caesarean cases by independent component analysis (ICA).
Results: The selected risk factors were more
contributory to public hospital patients than to those
in private hospitals on the basis of higher estimated
value of range (R = 0.134) but a higher proportion of
C-section occurred in private (93.4 %) than in public
hospitals (30.3 %). On the other hand, PCA showed that
the contribution of selected risk factors accounts for
approximately 60.0 % and 68.5 % in private and public
hospitals, respectively. Furthermore, from the various
graphical representation, the numbers of private
patients were more interlinked by ICA but not of the
other graphical representations of PCA.
Conclusion: We had expected the rate of
C-section would be higher among public hospital patients
than private hospital patients but the results obtained
indicate the reverse. It seems that the combination of
the propensity of private practice doctors to carry out
C-section and the financial benefits on the part of
private hospitals may be contributory factors to the
caesarean section rates in private health facilities.
