A usability study to improve a clinical decision support system for the prescription of antibiotic drugs

Abstract: ObjectiveA clinical decision support system (CDSS) for empirical antibiotic treatment has the potential to increase appropriate antibiotic use. Before using such a system on a broad scale, it needs to be tailored to the users preferred way of working. We have developed a CDSS for empirical antibiotic treatment in hospitalized adult patients. Here we determined in a usability study if the developed CDSS needed changes.MethodsFour prespecified patient cases, based on real life clinical scenarios, were evaluated … Show more

“…Most (n = 17/29) of the problems were cosmetic problems or minor problems. Eighteen (out of 29) of the usability categories could have an ordering error as a result [ 27 ]. To improve this the system was redesigned by enlarging information icons, introducing calculators, retrieving more patient information automatically from the hospital information system and introducing new options, such as the option to review the culture history in the final screen when an antibiotic advice is generated.…”

“…In addition we also included several infectious diseases on request of physicians. We performed a usability study as part of the development and evaluation phase [ 27 ], resulting in stakeholders being engaged in the further development and fine-tuning of the CDSS. The results of the usability study enabled us to make the CDSS more specific to users’ needs (for example by adding calculators).…”

“…A convenience sample of intervention participants was invited to participate in an accompanied shopping trip whereby the lead author observed them doing their usual supermarket shopping, using the think-aloud method that attempts to access and record participants’ inner speech, the transformation of thought processes into words [ 45 ]. The think-aloud method has been widely used in the design and evaluation of digital interventions [ 46 , 47 ] and to explore consumers’ food choice behaviors [ 48 - 51 ]. The accompanied shopping trip was followed by a one-on-one interview about the participants’ experiences of the intervention.…”

“…It is not easy to display the recommended antibiotics and their properties in a readily usable interface [16,17]. In the context of antibiotic treatment, several kinds of interface have been used, including textual formats [18,19], tables [19], diagrams [20], hypertextual links [21], and tick boxes [18]. Outside the domain of medicine, e-commerce interfaces (such as those used by e-commerce organizations like Booking, eBay, and Amazon) are widespread and make it possible for consumers to compare particular parameters between products.…”
