ObjectiveEating disorders (EDs) comprise a range of illnesses characterised by disordered eating, distressing thoughts, and changes in weight. EDs in the perinatal period are a growing concern. Maternity staff receive little training in this area and often report feeling ill-equipped to recognise or respond to presentations of ED during this time. The study aimed to develop and evaluate an online educational module for clinicians and support workers to improve knowledge of EDs in the perinatal period.MethodEducation modules were developed using a co-design process with consumer advocates, peer support workers, clinicians, and experts. Consumer perspectives, evidence-based videos, activities, and text relating to screening, management, monitoring and referral of perinatal individuals with EDs were included in the module. Quantitative and qualitative data from pre- and post- surveys were used to evaluate changes in knowledge and confidence before and after completing the module, and to assess staff satisfaction, usability, and obtain feedback for improvement.ResultsUse of the online education module significantly increased staff knowledge of EDs in the perinatal period. Participants also felt more confident in discussing the topic with patients, screening, supporting, and referring a person with ED in the perinatal period. Participants also reported the module was engaging and easy-to-use.ConclusionsFindings indicate that the ED online education module is an engaging and easy-to-use tool for improving the knowledge and skills of the healthcare workforce, thereby improving patient care and health outcomes. The development of additional online resources for clinicians would be beneficial for increasing staff capability and improving patient services. Eating disorders (ED) in pregnancy and after birth are a serious and growing concern for maternity services. Few educational and training options currently exist to support clinicians to identify and manage EDs during this time. The authors co-designed an online education module with lived experience consumers, peer workers, and clinicians, designed to improve identification, management, and referral of women experiencing ED's. Evaluation of the modules using online surveys showed that the online module was acceptable and engaging for users, and increased staff knowledge and confidence in identifying and managing these presentations. Online modules are a cost-effective resource that could improve staff capabilities and patient care in the long term.
