Patient Transport Module: Stroke PTM Feasibility Study Report
Co-Author: Marco Steinberg, Harvard University Graduate School of Design, 2003
Over 700,000 strokes are estimated to occur every year in the US with projected lifetime costs over $30B. For strokes caused by vessel obstruction, flow must be restored within a therapeutic time window, or irreversible tissue deaths results. Many external factors delay patients from seeking health care, and thus limit treatment within this time window. Therefore, once the patient has arrived in the emergency room, time is immensely important. However, 20 to 40 minutes can be lost prior to start of treatment with patient transfers between bed and radiologic device tables.
Reduce time to treatment by introducting new technology, the Stroke Patient Transport Module (PTM). The goal of the PTM is to improve the efficiency of workflow and to reduce or eliminate non-value-added interactions that delay start of treatment. The PTM would enable a stroke patient to proceed on a single, moveable surface designed to 'dock' with existing radiologic imaging equipment and to accomodate monitoring or treatment needs along the care route. The minutes saved through its use should have measurable impact on infarct volume and patient outcomes, thus changing the overall economic impact of stroke.
This first-phase study consisted of: (1) a detailed needs analysis, including analysis of existing patient benchmark data, to define performance requirements, and (2) identification of design strategies and workflow models based on these proposals.
