NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note “no longer under consideration” will appear above).
Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a “Peer-Review Me” button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed “version of record” (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
An algorithm for monitoring childbirth in settings where tracking all parameters in the WHO partograph is not feasible: design and expert validation
After determining the key childbirth monitoring items from experts in childbirth, we designed an algorithm to represent the experts’ suggestions and we validated it.
In this paper we describe the abridged algorithm for labour and delivery (LaD) management and use theoretical case to compare its performance to human childbirth experts.
The LaD algorithm encompasses the tracking of six of the 12 childbirth parameters monitored using the World Health Organisation partograph. It has recommendations on how to manage a patient when parameters are outside the normal ranges. We validated the algorithm with purposively selected experts selecting actions for a stratified sample of patient case scenarios. The experts’ selections were compared to get pairwise sensitivity and false positive rates (FPR) between them and the algorithm.
The mean weighted pairwise sensitivity among experts was 68.2% (StD. 6.95; CI. 59.6, 76.8) while that between the experts and LaD algorithm was 69.4% (StD. 17.95; CI. 47.1, 91.7). The pairwise FPR amongst the experts ranged from 12% to 33% with a mean of 23.9% (CI. 12.6, 35.2) and that between the experts and the algorithm ranged from 18% to 43% (mean 26.3%; CI. 13.3, 39.3). The was a correlation (mean of 0.67) in the actions selected by the expert pairs for the different patient cases with a reliability coefficient 0.91.
The LaD algorithm was more sensitive but with a higher FPR than the childbirth experts, although the differences were not statistically significant. An electronic tool for childbirth monitoring with fewer than WHO-recommended parameters may not be inferior to human experts in labour and delivery clinical decision support.
