| Popis: | Objective.—To profile physicians' practices, utilization, and understanding of human immunodeficiency virus type 1 RNA (viral load) testing and the laboratory's role in this testing. Design.—Cross sectional study using a 34-item self-report survey mailed to physicians identified as requesting viral load testing, with follow-up mailings to nonresponders. Participants.—A sampling of US physicians specializing in infectious diseases, internal medicine, and family practice associated with high, medium, and low human immunodeficiency virus/acquired immunodeficiency syndrome incidence areas. Results.—Most respondents using viral load results were infectious diseases specialists practicing in urban areas. The reasons most frequently given for requesting viral load testing were (1) to assist in patient follow-up or monitoring (75.4%), and (2) to initiate/guide therapy (62.5%). Respondents indicated that the interpretation and use of viral load results presented difficulty in the areas of patient treatment and in determining what change from baseline was clinically significant. Few respondents used the testing laboratory pathologist as a resource for interpreting viral load test results. Conclusions.—Our study indicates that physicians have questions about (1) the meaning of viral load tests, (2) how often to monitor the viral load, and (3) what change from baseline of the viral load is significant. Few physicians avail themselves of the expertise available in the laboratory for testing viral loads and interpreting such results. |
