Design and development of the BD Odon Device TM TM : a human factors evaluation process

摘要

Objective To (1) determine how intended users interact with and use theBD Odon Device in simulation, (2) use these findings to alter progressively the design of theBD Odon Device and (3) validate that these changes have improved the ability of practitioners to use theBD Odon Device.Design Human factors evaluation study. Setting Simulation suite designed to mimic delivery room. Population or sample Three hundred and ninety simulated operative births, performed by 100 practising clinicians. Methods Simulated operative vaginal births performed using theBD Odon Device and the deviceInstructions for use were subjected to three formative human factors evaluations and one human factors validation test. Following each evaluation, findings were reviewed and the design of theBD Odon Device and Instructions for use were modified.Main outcome measures Successful performance of an operative vaginal birth using theBD Odon Device in accordance with provided training andInstructions for use .Results Using version two of theBD Odon Device, and following exposure to facetoface training and written instructions, 25% of accouchers were able successfully to perform a simulated operative vaginal birth. In the final evaluation, following device design and training material alterations, all accouchers were able successfully to perform a simulated operative vaginal birth using version four of theBD Odon Device.Conclusions Human factors evaluations have enabled a multiprofessional device and training materials design team to alter the design of theBD Odon Device and theInstructions for use in an evidencebased fashion. This process has resulted in a device which has a predictable and likely safe pattern of use.Tweetable abstract Human Factors evaluations help make the BD Odon Device safe and usable for clinical practice.
