Increasing dependability in collaboration work among health professionals will directly improve patient outcomes, and re- duce healthcare costs. Our research examines the develop- ment of a shared visual display to facilitate data entry and val- idation of an electronic record during multidisciplinary team meeting discussion, where specialists discuss patient symp- toms, test results, and image findings. The problem of gen- erating an electronic record for patient files that will serve as a record of collaboration, communication and a guide for later tasks is addressed through use of the shared visual display. Shortcomings in user-informed designed, structured data-entry screens became evident when in actual use. Time constraints prompt the synopsis of discussion in acronyms, free text, abbreviations, and the use of inferences. We demon- strate how common ground, team cohesiveness and the use of a shared visual display can improve dependability, but these factors can also provide a false sense of security and increase vulnerability in the patient management system.
