study conducted at Christian Medical\nCollege (CMC) Teaching Hospital, Vellore, India on 14th August\n2014 to assess the accuracy of clinically estimated foetal weight upon\nlabour admission. Estimating foetal weight is a crucial factor in\nassessing maternal and foetal complications during and after labour.\nMedical notes of ninety-eight postnatal women who fulfilled the\ninclusion criteria were studied to evaluate the correlation between\ntheir recorded Estimated Foetal Weight (EFW) on admission and\nactual birth weight (ABW) of the newborn after delivery. Data\nconcerning maternal and foetal demographics was also noted.\nAccuracy was determined by absolute percentage error and\nproportion of estimates within 10% of ABW. Actual birth weights\nranged from 950-4080g. A strong positive correlation between EFW\nand ABW (r=0.904) was noted. Term deliveries (\u226540 weeks) in the\nnormal weight range (2500-4000g) had a 59.5% estimation accuracy\n(n=74) compared to pre-term (\u0026lt;40 weeks) with an estimation\naccuracy of 0% (n=2). Out of the term deliveries, macrosomic babies\n(\u0026gt;4000g) were underestimated by 25% (n=3) and low birthweight\n(LBW) babies were overestimated by 12.7% (n=9). Registrars who\nestimated foetal weight were accurate in babies within normal weight\nranges. However, there needs to be an improvement in predicting\nweight of macrosomic and LBW foetuses.

14th August\n2014 to assess the accuracy of clinically estimated foetal weight upon\nlabour admission. Estimating foetal weight is a crucial factor in\nassessing maternal and foetal complications during and after labour.\nMedical notes of ninety-eight postnatal women who fulfilled the\ninclusion criteria were studied to evaluate the correlation between\ntheir recorded Estimated Foetal Weight (EFW) on admission and\nactual birth weight (ABW) of the newborn after delivery. Data\nconcerning maternal and foetal demographics was also noted.\nAccuracy was determined by absolute percentage error and\nproportion of estimates within 10% of ABW. Actual birth weights\nranged from 950-4080g. A strong positive correlation between EFW\nand ABW (r=0.904) was noted. Term deliveries (\u226540 weeks) in the\nnormal weight range (2500-4000g) had a 59.5% estimation accuracy\n(n=74) compared to pre-term (\u0026lt;40 weeks) with an estimation\naccuracy of 0% (n=2). Out of the term deliveries, macrosomic babies\n(\u0026gt;4000g) were underestimated by 25% (n=3) and low birthweight\n(LBW) babies were overestimated by 12.7% (n=9). Registrars who\nestimated foetal weight were accurate in babies within normal weight\nranges. However, there needs to be an improvement in predicting\nweight of macrosomic and LBW foetuses.

at Christian Medical\nCollege (CMC) Teaching Hospital, Vellore, India on 14th August\n2014 to assess the accuracy of clinically estimated foetal weight upon\nlabour admission. Estimating foetal weight is a crucial factor in\nassessing maternal and foetal complications during and after labour.\nMedical notes of ninety-eight postnatal women who fulfilled the\ninclusion criteria were studied to evaluate the correlation between\ntheir recorded Estimated Foetal Weight (EFW) on admission and\nactual birth weight (ABW) of the newborn after delivery. Data\nconcerning maternal and foetal demographics was also noted.\nAccuracy was determined by absolute percentage error and\nproportion of estimates within 10% of ABW. Actual birth weights\nranged from 950-4080g. A strong positive correlation between EFW\nand ABW (r=0.904) was noted. Term deliveries (\u226540 weeks) in the\nnormal weight range (2500-4000g) had a 59.5% estimation accuracy\n(n=74) compared to pre-term (\u0026lt;40 weeks) with an estimation\naccuracy of 0% (n=2). Out of the term deliveries, macrosomic babies\n(\u0026gt;4000g) were underestimated by 25% (n=3) and low birthweight\n(LBW) babies were overestimated by 12.7% (n=9). Registrars who\nestimated foetal weight were accurate in babies within normal weight\nranges. However, there needs to be an improvement in predicting\nweight of macrosomic and LBW foetuses. We have suggested the use\nof an amended version of the Johnson\u0027s formula for the Indian\npopulation for improvement and a need to re-audit once\nimplemented.", "identifier": "https://doi.org/10.5281/zenodo.1110023", "inLanguage": {"@type": "Language", "alternateName": "eng", "name": "English"}, "keywords": "Clinical palpation, estimated foetal weight, pregnancy, India, Johnson\u0027s formula.", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "name": "Evaluating Accuracy of Foetal Weight Estimation by Clinicians in Christian Medical College Hospital, India and Its Correlation to Actual Birth Weight: A Clinical Audit", "publisher": {"@type": "Organization", "name": "Zenodo"}, "size": "181.43 KB", "url": "https://zenodo.org/records/1110023", "version": "10002899"}</script> <script src="/static/dist/js/invenio-app-rdm-landing-page-theme.9b56690388e335810f04.js"></script> <script src="/static/dist/js/9945.e11a5a6ff50535c72070.js"></script> <script src="/static/dist/js/1357.4e237807ffba81b213b0.js"></script> <script src="/static/dist/js/1644.2b2007bc83e4beeabfaf.js"></script> <script src="/static/dist/js/8962.cfabe841decd009221fd.js"></script> <script src="/static/dist/js/9300.a81535ba51a38f1472fe.js"></script> <script src="/static/dist/js/9693.dac033d778162b60d96f.js"></script> <script src="/static/dist/js/invenio-app-rdm-landing-page.024f3c02bb324ddef007.js"></script> <script src="/static/dist/js/previewer_theme.77f20174699c7786038a.js"></script> <script src="/static/dist/js/zenodo-rdm-citations.f6ca22bc7712ee9b03f7.js"></script> <div class="ui container info message cookie-banner hidden"> <i class="close icon"></i> <div> <i aria-hidden="true" class="info icon"></i> <p class="inline">This site uses cookies.
