There are wide variations in the gender makeup of speakers at national pediatric emergency medicine (PEM) conferences with no significant change in recent years. ⋯ Compared to NCE, women are underrepresented as speakers at APEMA, but not at SOEM. Abstract presenters are more likely to be women compared to invited speakers. While awards appear equally distributed, recipients do not mirror the proportion of women in PEM. Conference organizers and leaders in PEM should ensure gender equity in national recognition.

Clinical prediction models are created to help clinicians with medical decision making, aid in risk stratification, and improve diagnosis and/or prognosis. With growing availability of both prehospital and in-hospital observational registries and electronic health records, there is an opportunity to develop, validate, and incorporate prediction models into clinical practice. However, many prediction models have high risk of bias due to poor methodology. ⋯ There are eight steps that should be followed when developing and internally validating a prediction model: (1) problem definition, (2) coding of predictors, (3) addressing missing data, (4) ensuring adequate sample size, (5) variable selection, (6) evaluating model performance, (7) internal validation, and (8) model presentation. Subsequent steps include external validation, assessment of impact, and cost-effectiveness. By following these steps, researchers can develop a prediction model with the methodological rigor and quality required for prehospital and EM research.
