A Clinician-Centered Evaluation of the Usability of AHLTA and Automated Clinical Practice Guidelines at TAMC
Abstract
The subject of this investigation pertains to usability and automated clinical practice guidelines (aCPGs) in AHLTA, the military health system s (MHS) electronic health record (EHR). The purpose of the study is to examine critical usability issues in AHLTA, redesign and test these functions, and design and evaluate aCPGs by incorporating the improvements in usability. Four aims guide the work: (1) Determine critical AHLTA usability issues and develop a new AHLTA prototype by redesigning these AHLTA functions based upon user-centered design principles; (2) In a laboratory setting, compare clinicians performance using the current version of AHLTA and the redesigned functions in an AHLTA prototype derived from aim 1; (3) Using the existing Veteran s Administration and Department of Defense (VA/DoD) asthma clinical practice guideline as a foundation, convert it to an aCPG in AHLTA using user-centered design principles; and (4) In a laboratory setting, compare clinicians performance using the current asthma aCPG alternate input mode (AIM) form in AHLTA with the newly designed aCPG in an AHLTA prototype derived from aims 1 and 3.
