RISING CAESAREAN SECTION RATE

Abstract

Objective: Compare indications for caesarean section in Military Hospital Rawalpindi in the year 1999 with the year 2005, sixyears apart, with an aim to identify areas where caesarean section rates could be decreased. Study design: Prospective Survey of caesareansection using information provided by doctors/midwives entering data in labour ward /theater registers. Methods: The study was designed asa process evaluation. Indication for caesarean section, parity, previous caesarean section, emergency / elective, labour / pre labour, presenceof previous caesarean section scar, induced or spontaneous labour were noted. Data was plotted into 2 separate classifications and indicationscompared across the 2 years 1999 versus 2005. Statistical significance was calculated and value of <0.05 was considered significant. Results:Overall section rates rose from 16.9% to 34.6% which showed almost doubling of rates in a span of 6 years. The chief contributors to risingrates were as follows. Caesarean section rate rose from 132 (2.2%) to 355 (4.6%) for previous one Caesarean section (p<0.001), from 172(2.9%) to 383 (5% )for previous >1 caesarean (p<0.001), that for nullipara increased from 203 (3.3%) to 632 (8.3%), prelabour or induced labour(p<0.001) and for dystocia from 150(2.5%) to 490 (6.4%) which was again significant (p<0.001) . Increase in section rate for antepartumhaemorrhage, diabetes, previous infertility and intrauterine growth restriction was insignificant. Conclusion : A decrease in the number ofcaesarean sections may be achieved by reducing the number of primary caesarean section and/or encouraging more patients to take a trialof scar. A decrease in induction rates may also lead to lowering of caesarean section rates.
