Medina is a company based in the Netherlands that specialise in provision of anaesthesia in medical operations. We worked with Medina to specify and build a specialist iPad and iPhone application to do pre-operative screenings of patients. Patients are guided through the process, filling out a questionnaire on an iPad in the clinic and watching a video informing them of the procedures they will be going through. From this point the application manages the requirements for information and communication between the clinic, patient and anaesthesiologist in a secure way to the point where the operation can be booked. A back-end web function lets Medina manage the questionnaire and consent process.
