ORLANDO – Preoperative electrocardiograms (EKGs) had no effect on management or perioperative complications in women undergoing benign hysterectomy over a 12-month period at a single medical center, according to a review of records.
Of 587 patients included in the review, 182 (31%) underwent EKG as part of their preoperative evaluation, and the majority of those were indicated according to institutional criteria (166; 28%) or National Institute for Health Care Excellence (NICE) guidelines (177; 30%), Nemi M. Shah, MD, reported at the annual scientific meeting of the Society of Gynecologic Surgeons.
“EKG was indicated in 91% of these patients according to institutional criteria, and in 97% of patients per NICE criteria,” said Dr. Shah, a third-year resident at the University of Texas Southwestern Medical Center, Dallas.
By institutional criteria, hypertension was the most common indication (68% of cases), and by NICE criteria, American Society of Anesthesia class 2 physical status was the most common indication (80% of cases), she noted, adding that obesity, which was present in 70% of patients, was the most common comorbidity classifying patients with American Society of Anesthesia class 2 or above.
Of the 182 EKGs performed, findings were abnormal in 89, but further workup was pursued in only 16 patients, and included repeat EKG, echocardiogram, and/or stress testing and cardiology consultation. Surgical delays of 1 and 4 months occurred in 2 patients as a result of the additional workup, and ultimately, all planned hysterectomies were completed by the primary surgical team without changes in management, she said.
Perioperative complications occurred in two patients, and included nonspecific postinduction EKG changes that led to surgery being aborted in one patient who had left ventricular hypertrophy on the preoperative EKG, and failed extubation in a patient with airway edema whose preoperative EKG showed a nonacute inferior infarct.
For the first, cardiology was consulted and determined the findings to be benign; the patient underwent hysterectomy at a later date without complications. The second patient was taken to the surgical intensive care unit for management, Dr. Shah said.
“Preoperative testing for benign hysterectomy is variable as there is no single standard of care,” she explained. “Though tests such as EKG are commonly ordered, there are no data linking study results to surgical outcomes.”
The current study was conducted to evaluate the rate of preoperative EKG performed in concordance with institutional and NICE guidelines, and to assess implications for management and perioperative complications.
Patients included in the review were adult women who underwent scheduled benign hysterectomy during 2016. Women who underwent emergency surgery or whose surgery was performed by gynecologic oncologists were excluded.
Subjects were primarily Hispanic, and had a mean age of 45 years, Dr. Shah noted.
Though limited by the single-center design and retrospective nature of the study, the findings suggest that preoperative EKG has little clinical utility.
“We found that practice patterns were highly concordant with institutional and NICE guidelines. However, EKG resulted in minimal impact on perioperative management, and no association between abnormal EKG and perioperative complications was found,” she said. “EKG may not accurately stratify perioperative cardiopulmonary risk, and alternative methods for preoperative evaluation should be considered.”
Dr. Shah reported having no disclosures.
