<p>PowerPoint Presentation</p> <p>Peter P. Mitchell, Ph.D., CHFPErgo Research, LLC</p> <p>I wonder if the People + Technology contract is changingThe analogy: John Locke and the social contractIn both, one gives up some of their individualism</p> <p>But, let us talk about patient safety</p> <p>Who Should Be In Charge?</p> <p>The concept: People can be shielded from harm through a well-conceived deal with technology. Alarms.</p> <p>These are good, but are reactive. Thinking conceptually, what would be the next step?</p> <p>I would like to offer an example.</p> <p>An intrathecal infusion pump.</p> <p>Shielded from Harm, Are Patients? </p> <p>The Pump is Surgically Implanted</p> <p>Drug Flow Rate is Controlled By:</p> <p>When delivered from factory saline in the tubing.</p> <p>User sets a very high flow rate: 1,000 units per hour get all of the saline out.</p> <p>After approximately 20 minutes change to the patient dosage, 3 units per hour (never higher than 20).</p> <p>A doctor designated to change flow, all of his attention resources = on surgery. Did not make the change.</p> <p>Need to Drain Saline Solution</p> <p>The result: patient gets 1,000 units per hour, not 3 units.</p> <p>In the Root Cause Analysis that was done, focus was on the people part of the equation.</p> <p>Wait, this is simple. We are making it harder than it is.</p> <p>The machine knows 1,000 units per hour is wrong. Use your (anthropomorphism) head do something.Patient Receives 1,000 Units/Hr. </p> <p>So our social contract: People + Machines = changing.</p> <p>Technology is saying: Not only can I address things that occurred previously, I am now going to look into the future.</p> <p>What if medical devices knew of errors in the future?Its a New Dawn Anticipate Future</p> <p>Better Error Avoidance than Medicine</p> <p>So this machine sees errors two cars ahead.</p> <p>Medical devices that see into the future?</p> <p>What is the implication for human factors and the user experience?</p> <p>And what does this say about the social contract between machines &amp; humans?Is This Right?</p>
