Robotic surgical telepathology between the Iron Mountain and Milwaukee Department of Veterans Affairs Medical Centers: a 12-year experience.

摘要

Since mid-1996, we have operated a diagnostic robotic telepathology (TP) system at the Iron Mountain, MI, Department of Veterans Affairs Medical Center (VAMC) from the Milwaukee, WI, VAMC, located some 220 miles away. No on-site pathologist is present in Iron Mountain. Instead, an experienced, well-trained pathologist assistant, under direction of pathologists located in Milwaukee, is responsible for tissue grossing and sectioning. The pathologist assistant places slides onto the stage of the robotic microscope, which is then controlled by pathologists in Milwaukee. Each case read by TP is subsequently read by light microscopy (LM) by the same pathologist. Three distinct phases of TP have been recognized. Our experience during phase I (mid-1996 to early 1999) has been published previously. During phase II (early 1999 to mid-2004), 1 of the 2 senior telepathologists in phase I retired, and 3 junior pathologists were hired. During phase III (mid-2004 to June 2008), 2 new junior pathologists were hired, and ASAP Imaging (Apollo Telemedicine, Inc., Falls Church, VA) was implemented. The number of TP case opportunities in phases I, II, and III was 2200, 5841, and 3512, respectively, resulting in a total of 11 553. A total of 1834 cases were deferred to LM for a variety of reasons. The number of TP diagnoses rendered in phases I, II, and III was 2144, 4636, and 2939, respectively, resulting in a total of 9719. The major discordance rates in phases I, II, and III were 0.33%, 0.45%, and 0.20%, respectively, with an overall rate of 0.35%. Pathologist-specific discordance rates were not significantly different and ranged from a low of 0.12% to a high of 0.77%, whereas case deferral rates were significantly different (P < .0001) and ranged from 2.5% to 28.7%. In general, no relationship between deferral rate and discordance rate was noted. Iron Mountain clinicians have expressed great satisfaction with the services provided by their off-site pathologist colleagues.
