In 2008, Army Medical Command initiated a plan to standardize behavioral health (BH) care practices across all Army installations. The current electronic medical record was not capable of meeting the standardized practice needs of BH clinics. Therefore, the Behavioral Health Data Portal (BHDP) was developed to help standardize BH clinical data collection and outcome tracking. As BHDP implementation was accelerated, determining the current BH provider usability and acceptance of BHDP was imperative so implementation plans and future enhancements of BHDP could be smartly shaped. A usability survey was developed and sent to 1871 BH providers using BHDP and 442 completed the survey (24.7%). Three hypotheses were tested: (1) Provider characteristics and computer familiarity would affect usability levels; (2) Amount of BHDP use and proportion of clinical care using BHDP will affect usability scores; and (3) BHDP use will positively affect targeted clinical actions.
