Abstract:

Aim: To design and evaluate a clinical decision support system (CDSS) to support cardiovascular risk prevention in type 2 diabetes. Methods: A preliminary requirements specification and three prototype CDSS interface designs were developed. Seven patients and seven clinicians conducted `usability tests' on five different task scenarios with the CDSS prototypes to test its effectiveness, efficiency and `user-friendliness'. Structured, qualitative questions explored their preferences for the different designs and overall impressions of clinical usefulness. Results: Patients and clinicians were enthusiastic about the CDSS and used it confidently after a short learning period. Some patients had difficulty interpreting clinical data, but most were keen to see the CDSS used to help them understand their diabetes, provided a clinician explained their results. Clinicians' main concern was that the CDSS would increase consultation times. Changes suggested by users were incorporated into the final interface design. Conclusion: We have successfully incorporated patients' and clinicians' views into the design of a CDSS, but it was an arduous process.
