It is imperative that we properly identify all films. This is extremely important in comparison studies, follow-up examinations, and for medicolegal cases. The proper identification should include the following information:
- Patient's name
- Patient's age or date of birth and gender
- Date of study
- Location where the study was performed
- Markers are essential to designate right and left
Other information that is not essential but suggested:
- Name of referring physician: If you are taking x-rays for another doctor, be sure the referring doctor's name is on the films, otherwise you may be liable for a patient you never examined.
- Identification number, case number or social security number of the patient. Larger institutions use a number system for filing films.
- It is strongly recommended that markers be utilized to designate patient position and special projections, i.e., upright, recumbent, left anterior oblique, etc.
If you are not presently labeling your films with this information, start now. There are numerous methods available for marking x-rays. Translucent identification cards are the most common. The information is typed onto the card. Please don't write the information by hand; it is much easier to identify the patient's films if the information is legible. This information is transferred photographically to the x-ray film using a film identification printer.
An older method but still just as efficient is the aluminum marker plate which has grooves for the placement of lead numbers and letters for labeling the film when the exposure is performed on the patient.
The most recent advanced method to date is with an identification camera in conjunction with cassettes. The cassette is inserted into the camera, a slide cover on the cassette is open and the identification exposure is made. The exposure is automatically timed so that you can never over or underexpose the marker.
The time spent performing the task of identifying your films will save you the embarrassment of criticism in the courthouse and will better protect your patients.
