PatientOS is a free healthcare information management system designed for hospitals and healthcare practitioners. This software is for physicians, nurses, pharmacist, the laboratory, and eventually all hospital departments and clinicians.
This version adds major scheduling functionality. Appointment types can be defined in batches, double, or any number of overbooking predefined on the schedule with all appointments defined with a custom color. Appointments can be rescheduled. Multiple resources can be viewed by day or week. Custom work schedules and blocking out of schedules were added.
