2.1 Scientific Background and Gaps The literature has shown that patients with dermatologic conditions may not receive appropriate management by PCPs. Dermatologic conditions are common, affecting 20-36% of patients in PCP offices; however PCPs report diagnostic and management uncertainty.1,2 PCPs have been shown to prescribe either inappropriately high-potency TCS or, conversely, inappropriately low-potency TCS.3 In addition, it was recently found that drug costs may be higher if multiple small tubes are dispensed over the treatment course.4 Thus, there are opportunities to reduce cost by prescribing larger units, when indicated; however PCPs may not have the knowledge to effectively and cost-efficiently prescribe TCS. Teaching this information is not sufficient, since most (71%) medical schools provided nine or fewer hours of instruction in the first two years.5 Importantly, mobile devices and apps provide significantly increased access to point-of-care tools and, with use by providers, demonstrate better clinical decision-making and improved patient outcomes.6,7 Thus, our goal is to develop a point-of-care decision support app to educate PCPs while facilitating evidence-based care and lower health care costs.
