Addition of Efficiency Measures to Current Accuracy Measures in the Vascular Laboratory Can Be Used for Future Accreditation and Payment Models.
Annals of vascular surgery(2020)
Abstract
BACKGROUND:The Medicare Access and CHIP Reauthorization Act (MACRA) brings with it increased regulatory requirements not traditionally addressed by standard vascular laboratory accreditation, which is based on accuracy. The new quality improvement project of the Intersocietal Accreditation Commission (IAC) may satisfy an improvement activity (IA) of the MACRA. We hypothesize that other IAs in the MACRA such as timeliness of test results or patient care quality performance requirements can be met by analyzing data already being collected by the vascular laboratory. After a process improvement strategy, we chose to review progress in our vascular laboratory related to time to interpretation (TI), patient check-in to study completion (study time), wait time for first available outpatient venous duplex scan (wait time), technologist productivity, and critical results reporting.
METHODS:Data from our hospital-based vascular laboratory were collected from 2010 to 2016. TI was collected through our reporting software VascuPro (Consensus Medical), and study time and wait time were obtained from electronic medical records (EMR) (Epic). Technologist productivity was calculated by commercially available productivity tools, and compliance with critical results reporting was calculated quarterly as per our quality assurance program. Appropriateness of carotid duplex scan testing was performed by expert review of International Classification of Disease codes used to request the test.
RESULTS:TI analysis comprised 91,352 studies with a mean of 3.3 hr between test completion and final interpretation. The TI improved from 5.0 to 2.1 hr on weekdays and was longer on weekends (4.9 hr; P < 0.001). The study time improved from 29.8 to 27.2 min and was 14.9 min shorter on the weekends (P < 0.001). The wait time ranged from a mean of 1-2.08 days. Technologist productivity improved from 90.7% to 93.6%. Critical results reporting quarterly audits showed a 100% compliance rate. On expert review, the International Classification of Disease code on carotid duplex scan requests in the EMR was deemed inaccurate in 17.4% of cases.
CONCLUSIONS:TI and study time improved; wait time and critical results reporting remained steady. Most of the data are readily available in a vascular laboratory standard EMR. The plan-do-study-act (PDSA or Shewhart Cycle) principle is critical to process improvement and needed as we transition from traditional accreditation mostly based on test accuracy to one demanding efficiency, timeliness, patient satisfaction, productivity, accountability, and appropriateness of testing. Process improvement studies will improve patient care and satisfaction, increase efficiency and throughput, while satisfying changing IAC standards and preparing for upcoming regulatory requirements of the MACRA.
