‘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)

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
