The hospital must employ an internal survey system in place to be able to manage the procedure. At this stage, usually more information needs to be gathered and improvements need to be made before the official survey report can be carried out. Depending on the size and complexity of the hospital, a big or small survey team extensively investigates the hospital environment for a couple and up to five days. The team is granted full access to all areas and full cooperation of all employees. A draft survey report and action plan identifies the improvements that the hospital needs to make in order to qualify for accreditation. Once improvements are made and checked, the survey report goes to the College for Quality Certificates, a body that judges the qualification. After four years the accreditation cycle repeats itself.
