The PICU Essentials app was designed as a practical handbook for rotating residents, advanced practice providers and fellows. It is based on 20 years of PICU practices. While much of the content describes practices or protocols at UF Health Shands Children’s Hospital, it could be applied in most settings. All content is peer-reviewed, and new content is added frequently. All subscription fees go directly to the maintenance of the app. For questions regarding the app please contact Charlene Pringle email@example.com.
