Reducing Unnecessary Type and Screens Prior to Thoracic Surgery: A Quality Improvement Initiative

Abstract

Introduction: Previous work identified that routine preoperative type and screen (T&S) testing before elective thoracic surgery is overutilized. We hypothesized that instituting a quality improvement (QI) initiative to change practice would significantly reduce this unnecessary testing, reduce costs, and improve healthcare efficiency.

Materials and methods: A QI initiative was developed at a single, academic center to reduce empiric T&S ordering before elective anatomic lung resections. Two interventions were implemented: 1) education based on current institutional data and 2) an electronic medical record order set modification. Utilization of T&S testing, blood transfusion data, and perioperative outcomes were tracked and compared between a preintervention group (2015-2018) and a postintervention group (2020-2021). Cost data were derived from institutional charges and Centers for Medicare & Medicaid Services fee schedules.

Results: Of the 553 patients included: 420 were in the preintervention group and 133 were in the postintervention group. The rate of routine T&Ss significantly dropped after implementing the QI initiative (97 versus 20%, P ≤ 0.001). Additionally, no difference in blood transfusion rate was observed (4.3 versus 2.3%, P = 0.29), and there were no differences noted in postoperative complications (P = 0.82), 30-day readmission (P = 0.29), or mortality (P = 0.96). Based on current volumes of ∼200 anatomic lung resections/year, estimated cost savings from reducing T&S testing from 97 to 20% would be at least $40,000 a year.

Conclusions: Our QI initiative significantly reduced the use of routine T&S testing. This practice change was achieved while maintaining excellent outcomes demonstrating routine preoperative T&S testing can be safely reduced in most elective thoracic surgery.
