Operating theater books contain detailed records of surgical procedures and patients, which are used for planning and ordering supplies. These confidential records provide information on patient care journeys. Traditional paper-based operating theater books included patient names, ages, addresses, diagnoses, attending medical staff, dates and times of operations, and anesthetics used. While some organizations still use handwritten records, computer-based systems provide more secure, efficient access to records for medical staff in emergencies. Computer networks allow records to be easily accessed from any location in the hospital and save medical personnel time retrieving files. Computerized records also improve patient care, safety, and decision making.
