Data on length of parathyroidectomy surgery and intraoperative parathyroid hormone (PTH) assay turnaround times following a switch in the location for intraoperative PTH testing from near point-of-care to central laboratory

Intraoperative monitoring of parathyroid hormone (PTH) is commonly used during parathyroidectomies. There are a number of practical challenges in achieving rapid turnaround time (TAT) for intraoperative PTH testing, whether the testing is performed point-of-care, near point-of-care, or in a central clinical laboratory. In the related research article, we analyzed a decade of data from 3025 intraoperative PTH tests on 897 unique patients. Of these, 1787 tests on 514 unique patients (375 female, 139 male) occurred while intraoperative PTH measurement was done as near point-of-care testing; the remaining 1238 tests on 383 unique patients (282 female, 101 male) occurred after a switch to intraoperative PTH measurement by the hospital central laboratory. The data in this article provides the patient age, gender, location of surgery (main operating rooms vs. ambulatory surgery center), incision to close time for surgery, and operation start to end times. For the central laboratory testing, additional data are provided for the intraoperative PTH TAT. The analyzed data is provided in the supplementary tables included in this article. Plots of operation start and end times are also included. The dataset reported is related to the research article entitled “Evaluation of Switch from Satellite Laboratory to Central Laboratory for Testing of Intraoperative Parathyroid Hormone” [D. Jacob, G. Lal, D.R. Voss, T. Bebber, S.R. David, J. Kulhavy, S.L. Sugg, A.E. Merrill, M.D. Krasowski, Evaluation of Switch from Satellite Laboratory to Central Laboratory for Testing of Intraoperative Parathyroid Hormone, Pract. Lab. Med. (2020) 22: e00176] [1]

Value of the Data
• The data provided is of value as intraoperative PTH measurements present multiple practical challenges.
• Clinicians, other researchers, or personnel in clinical laboratories might find this data useful as a reference for comparison. • There are limited published data sets that include intraoperative PTH turnaround time.
• The data is of value as there is very limited published data on impact of intraoperative PTH testing on the length of parathyroidectomy surgeries. • The data provide information for 3025 measurements in 897 unique patients undergoing parathyroidectomy.

Data Description
In this retrospective study, we assembled data on 3025 intraoperative PTH measurements on 897 unique patients who had parathyroid surgery. There are many practical challenges that impact TAT for intraoperative PTH [2][3][4][5][6][7][8][9][10] . These include geographic location of operating rooms, transport of samples to testing location, analysis time, and method of reporting of results to the surgical team. Fig. 1 shows operation start and end times for parathyroidectomies performed before and after switch from near point-of-care to central laboratory measurement of intraoperative PTH. The related research article [1] shows plots for incision to close times, a measure of surgery time less affected by other factors unrelated to intraoperative PTH measurement. The raw data are included in Supplementary file 1 (satellite laboratory performing near point-of-care intraoperative PTH testing) and Supplementary file 2 (central laboratory performing testing).
• Supplementary file 1: Data for 1787 intraoperative PTH measurements on 514 unique patients (375 female, 139 male) undergoing parathyroidectomies in which intraoperative PTH was monitored by near point-of-care testing. Specific data fields include: test type (baseline intraoperative PTH measurement versus measurements after gland removal), age in years, birth sex, location of surgery (main operating room versus more distantly located ambulatory surgery center), incision to close time (mins), and operating start to end times (mins). • Supplementary file 2: Data for 1238 intraoperative PTH measurements on 383 unique patients (282 female, 101 male) undergoing parathyroidectomies in which intraoperative PTH testing was performed in the central laboratory. Specific data fields include: test type (baseline intraoperative PTH measurement versus measurements after gland removal), specimen collect to received in laboratory time (mins), specimen received to result verified time (mins), total TAT (mins), age in years, birth sex, location of surgery (main operating room versus ambulatory surgery center), incision to close time (mins), and operating start to end times (mins).

Experimental Design, Materials, and Methods
The data were collected as part of a retrospective study approved by the University of Iowa Institutional Review Board (protocol # 201903764) covering the time frame from May 1, 2009 to February 21, 2019. The electronic health record (EHR) for the institution is Epic (Epic, Inc., Madison, WI). Epic Reporting Workbench (RWB), a reporting tool within the electronic medical record, was used to capture all intraoperative PTH orders in the retrospective time period [11] . Data fields that were accessible in RWB further extracted parathyroidectomy incision and close times and operation start to end times for all parathyroidectomies associated with intraoperative PTH measurements. For the data where intraoperative PTH was measured in the central laboratory, additional data fields were pulled to include specimen collection time, specimen received in central laboratory time, and time of verified result in the electronic medical record. Intraoperative PTH TAT was not available for the near point-of-care data as this was not routinely captured.
