‘Missed Results’ ProblemMishandling of abnormal results & no follow-up
(Wahls, 2007)
Most common missing information: lab test results (Dovey, 2002)
Delay in care, time/financial loss, pain/suffering, adverse clinical consequence (Hickner, 2008)

Test Process Steps1. Pre-analytic
a. Ordering the testb. Implementing the test
2. Analytica. Performing the test
3. Post-analytica. Reporting results to the clinicianb. Responding to the resultsc. Notifying the patients of the resultsd. Following-up to ensure the patient took the appropriate
action based on test results

Approach for Reducing Missed Results
Model user actions within workflow specificationAssign temporal responsibility
Derive an interactive display from the modelFrom order time to until all follow-up actions are
takenSupport actor action sheets as part of tracking
Provide retrospective analyses for manager to identify common problems and compare performance

Actions, Groups, and Values
Evaluation Plans for ASAP Iterative Design Reviews with Medical Professionals
Usability Test 10 subjects, 25 tasks (1 hour) Inform design Feedback: Interview, Questionnaire
Controlled Experiment Test whether ASAP reduces the amount of missed and
delayed results Busy simulation environment where multiple distracting
factors are in place Compare to a plain list ordered by time of arrival 20 participants, 50 tasks (2 hours)
April 21, 2023 19
SummaryModel user actions within workflow specification
Allow actions as part of display
Integrate review of results with possible actor actions from within same screen
Tracking shows how much time has passed since last action
