ABSTRACT
EXECUTIVE SUMMARY: Timely access to services is the gateway to patient safety and quality, and scheduling is foundational to providing access to highly reliable care. An effective and efficient scheduling strategy is dependent on an evidence-based approach that focuses on critical drivers of the scheduling system related to patient safety and quality as well as access. As part of a continuing effort to improve access, the Veterans Health Administration (VHA) completed a direct causation analysis (2015-2020) using an evidence-based framework and comprehensive measurement plan. The analysis, described here, validates access benefits realized specialty by specialty and facility by facility, identifies opportunities for improvement, and acknowledges limitations of the change from the Veterans Information Systems and Technology Architecture scheduling system to the Medical Appointment Scheduling System.This analysis of the assessments illustrates business validation structures, drivers, processes, and outcomes that can support leadership decision-making related to access. We drew our assessments of people, processes, policies, and technology from on-site interviews, over-the-shoulder observations, large-group discussions, and data from the VHA Support Service Center and facility data systems; we also mapped process steps, keystrokes, and workflow. Our assessments provided support for the VHA's decision to implement the stand-alone Cerner scheduling system at one site while continuing to implement the Cerner Millennium electronic health record platform that includes the Cerner scheduling system at other VHA sites. The VHA experience provides lessons learned for healthcare leaders who seek highly reliable efforts to improve access to care.
