OBJECTIVE:  To provide accurate and timely diagnoses of diseased tissues removed at the Interim LSU Hospital.

DIAGNOSTIC AND CONSULTATIVE SERVICES
All surgical specimens on human tissues removed in the Hospital must be sent to the Pathology Department where they will be properly processed, examined and reported.

Material received in the Surgical Pathology Laboratory is assigned to either the LSU or Tulane service based on admission demographics. Medical school designations cannot be arbitrarily changed; each specimen becomes the responsibility of the designated school service.

All specimens must be identified with the patient's name, clinic or ward, hospital number, and the type of tissue submitted. Clinical diagnoses, relevant history, and operative findings should be included on the pathology request slip. The submitting physician must sign the slip. In case of any apparent incorrect labeling or mix-up in the identification of a biopsy specimen, such specimen will not be processed by the laboratory until resolved. Specimens should be transported directly from the operating room or the treatment room to the Pathology Laboratory.

The proper identification of the specimen and the care and preservation of the specimen are the responsibility of the attending physician until the specimen is received in the Pathology Laboratory.

Surgical specimens must not be removed from the hospital prior to the examination by the Pathologist. Special research techniques or surgical materials are never indicated as a primary procedure. If a positive diagnosis has been made on biopsy material, additional biopsies may subsequently be taken for special research techniques.

Diagnostic studies on tissue processed by routine histopathology techniques are required by hospital rules. Deviations from this standard procedure will be referred to the Director of Surgical Pathology who will notify the appropriate clinician for resolution. It is the responsibility of the clinician to alert the pathologist to the need for bacteriologic studies. Material to be cultured should be submitted in a sterile container and should be kept separate from material submitted for histopathology study. If a question arises regarding the techniques for obtaining and handling tissue for culture, the clinician should consult with the Pathology Laboratory. 

SLIDES FROM OTHER HOSPITALS
If it is necessary to request slides from private hospitals or from other institutions on individuals who are presently patients at Interim LSU Hospital, please submit your request for these slides through the Histopathology office. The letter should be signed by the requesting physician. Similarly, requests for consultation from outside institution/physician’s office will be processed likewise. As soon as the slides arrive, they will be assigned a special number and examined by the appropriate surgical pathology service. A copy of the report will be generated and sent to the requesting physician, and transmitted to the patient’s electronic health record.

CONSULTATIONS
Consultations between the pathology laboratories of the two local medical schools should be handled in a formal manner. The clinician who desires the consultation should request that the slides be sent to the consultant by the responsible pathologist. A verbal report which results from an informal consultation cannot be used to legally justify a particular type of treatment and is not recognized by Interim LSU Hospital.

SLIDE CHECK OUT
Slides which are needed for conference directly concerned with medical care may be checked out of the files at the Interim LSU Hospital, but should be promptly returned. Physicians who do not comply with this rule will lose their privileges in the Pathology Laboratory. Problem cases will be referred to the Chief on the respective service. Lack of cooperation at this level will result in the loss of privileges for the respective service. These cases will be referred to the Hospital Director.

The slide becomes part of the permanent hospital record of the patient. The paraffin block is also part of the permanent record and should be preserved in anticipation of the need for additional studies. Wet gross tissue is saved for a one month period of time following the final interpretation of the histopathology preparations. This wet gross tissue is available to the two medical schools for preparations of study sets or for additional studies.

Sections prepared from paraffin blocks of surgical pathology material at either of the two medical schools should be given Interim LSU Hospital labels and should be returned to the files at Interim LSU Hospital following completion of indicated studies. It is not the responsibility of the Pathology Laboratory to furnish slide sets to residents in training. Abuses of the files in the Pathology Laboratory will be referred to the Director of the Laboratory.

 Gross surgical specimens are dissected and described every day in the Histopathology Laboratory. The house staff is invited to review the gross specimens by arranging a convenient time with the Pathology residents on each service (903-2417)). No surgical specimen is to be dissected by anyone other than a member of the Pathology staff without specific approval of the responsible pathologist.

In cases where the surgeon wishes to see the specimen dissected in the operating room, a member of the pathology staff assigned to frozen sections should be called to assist in or perform this service.

The material received in the Laboratory must correspond to that indicated by the surgeon in his description of the operative findings and of the specimens removed. Discrepancies will be referred to the Senior Resident of the responsible LSU or Tulane pathology service and the Director of Surgical Pathology.

FROZEN SECTION CONSULTATION
 Frozen section consultation should be scheduled when the operation is scheduled. A frozen section generally is indicated when there is a need for an immediate therapeutic decision. Occasionally, a frozen section is indicated to shorten the patient's hospital stay or to qualify the patient for an emergency status on the operative schedule. Frozen sections are not indicated for the personal convenience of the surgeon when an immediate therapeutic decision is not involved.

Request for frozen section consultations should be accompanied by a pathology request slip with adequate documentation of the need for frozen section. The concept behind the frozen section is that of consultation between physicians. A pathologist will be on call for emergency frozen section consultations in any cases in which a frozen section has not been scheduled, and can be reached via the paging operator.
