Illustration of two-step approach to screening mothers for CPD. Step one: simple screening with a tape measure and smartphone application to calculate tape measure-based risk score. If the tape measure risk score shows low risk, the mother follows best local labour and delivery practice. If the tape measure risk score shows moderate or high risk, the mother receives additional screening via the 3D camera-based tool. Mothers that score as moderate or high risk are referred to a hospital with emergency C/S capabilities; low-risk mothers follow best local labour and delivery practice.
