Train the Trainer Curriculum to Scale up AI Supported Echo for RHD Screening in a Public Health System

A four-day training program taken over the course of two weekends will include materials on RHD and RHD echocardiographic screening using focused artificial intelligence navigational guided echocardiographic acquisition to identify patients who are screen positive or screen negative for RHD. The echo protocol will be limited to the parasternal long axis-view (2D and color Doppler) focusing on mitral and aortic valve morphology and function and a single 2D apical 4 chamber view for auto EF. The curriculum package will include online modules, instructor delivered PowerPoint presentations, and hands on practice on volunteers with and without RHD.

A pre- and post-training test on RHD knowledge and diagnosis will be administered. A rapid competency assessment, including obtaining imaging on volunteers with or without RHD and an online test with pre-recorded cases of RHD, LV dysfunction and Pericardial effusions, will be utilized at the end of the 4-day training sessions. Trainees will be monitored by trained study personnel and at the end of the practicum training, the expert users will blindly review and assess the quality of each study using the standardized scale and competency scorecard provided below. Additionally, they will be asked to pass the knowledge quiz (80% or better). If competency is not achieved, an additional weekend of training can be added.

"Following certification, the certified MOH nurses will integrate echocardiographic screening into the routine workflow at the 4 HCIII/IV clinics with each nurse carrying out screening at the assigned HC on patients (aged 5-40) presenting to the health center for routine care.~Screening will be done daily over a period of one month. A minimum total of 400 participants will be screened during this period; each nurse will screen as many patients as they can, with a minimum of 100 participants (at least 5 participants per day). At the end of each screen, the trainees will interpret the screen as screen negative or screen positive. They will go ahead to refer participants identified as screen positives to the district hospital (LRRH) for a confirmatory echo.~At the end of each screening day, all images will be uploaded to a cloud server for a confirmatory review by a cardiology fellow or cardiology attending physician, within in 1 - 2 weeks."

Each Primary Trained MOH Nurse will train 3 other nurses from their Health Center using pre-recorded PowerPoints.

The secondarily trained nurses will be assessed and certified by the nurse trainer.
