3) shows that all interactions were brief, with the longest <strong>of</strong> those taking place in the<br />

patient room, but lasting less than two minutes in duration. Of the <strong>communication</strong><br />

tasks, “Being Taught” had the longest average time (1m 35s) followed by “Discussing<br />

Patient Care” <strong>and</strong> “Providing Assistance” (43s each), “Seeking Advice” <strong>and</strong> “Social”<br />

(39s each), <strong>and</strong> “Validation” (30s) (See Figure 22). Table 3 shows that, on average,<br />

over three hours are spent in the patient room in an 8-hour shift, <strong>and</strong> over two hours<br />

are spent in non-interactive tasks. Walking on the unit (the most frequently occurring<br />

task) accounted for nearly an hour <strong>of</strong> an 8-hour shift, yet each “In Transit” event<br />

averaged only 20s.<br />
