GNK-PIMS Score: A Predictive Model for Success of External Cephalic Version

Objective To determine association of GNK-PIMS score vs Newmann Peacock score with success of external cephalic version (ECV). Materials and methods This comparative cross-sectional analysis was carried out at MCH center Unit I, PIMS, Islamabad, from 1st January 2006 to 31st December 2009. Characteristics of 166 breech versions performed during study period were integrated into both Newmann Peacock score and GNK-PIMS score. Association of the two scoring systems with success of ECV was determined using Student t-test, correlation coefficient, Chi-square test and Cox and Snell test. The individual characteristics of two scores were also evaluated by stepwise linear regression model. Results The success rate of ECV was 49.9%. Newman Peacock score had weaker correlation with success of ECV (r = 0.234, p = 0.001) than GNK-PIMS score (r = 0.716, p = 0.000). The success rate was 6.3% at a score of 8 with Newmann Peacock score while that with GNKPIMS score was nil at a score of 8. All individual parameters of the GNK-PIMS score had significant association with success of ECV compared to only three variables of Newman Peacock score. Conclusion GNK-PIMS score is stronger predictor of ECV success than Newman Peacock score. Larger randomized controlled trials should be conducted based on this scoring system.
