<strong>Acute</strong> <strong>Care</strong> UnitNURSES’ BACKGROUND• 26 patients - all ages and conditions• 6 patients per nurse• Average length <strong>of</strong> patient stay is 3-5 days• Majority <strong>of</strong> patients are there for a “tune-up”• 25% <strong>of</strong> day spent doing charting and documentationStaff consists <strong>of</strong>:• Charge nurses• Registered Nurses• Licensed Nurse Practitioners• Certified Nurse AssistantsTraining• Most <strong>of</strong> training is in school not in the workplace• Orientation course for lifting techniques• Yearly updates• Post-injury counseling and trainingDEA470/670 2003, © <strong>Cornell</strong> <strong>University</strong>
A Typical Nurse’s DayNURSES’ BACKGROUND3 Different work shifts:• 8 hour day shifts ie. 7am to 3:30 pm• 12 hour day night shifts ie. 7am to 7pm• 12 hour evening shifts ie. 7pm to 7amDaily ScheduleFirst 2 hours: Arrive and begin patient care, rounds with doctors1 hour: Charting/computer work2 hours: Second round <strong>of</strong> medication, x-rays etc1 hour: Charting/computer work2 hours: Rounds/patient careDEA470/670 2003, © <strong>Cornell</strong> <strong>University</strong>

Computer Workstations• Workstation design is sufficient• Change to downward sloping keyboards• Offer training in proper and safe computer use• A great amount <strong>of</strong> force is needed to adjust height -change to an easier grip and reduce resistanceSUGGESTIONSDEA470/670 2003, © <strong>Cornell</strong> <strong>University</strong>
Sliding patient to headboardSUGGESTIONSOptions:• “Conveyer belt” sheet that cycles around the bedby pressing a button or using a crank• Install handles on existing sheets• Use same system but step to head <strong>of</strong> bed instead<strong>of</strong> swinging body• Hold person and lift to headboard instead <strong>of</strong> usingthe sheet and personMost important changeis to have a better gripDEA470/670 2003, © <strong>Cornell</strong> <strong>University</strong>
Changing IV BagOptions:• Have a chair-like foot pump to raise and lower theheight <strong>of</strong> the IV bag• Install an up and down button for adjusting heightSUGGESTIONSThe current stands are height adjustable, but it takestoo long and requires too much effort. A simpler, easiersystem would encourage proper use and reduceinjuries.DEA470/670 2003, © <strong>Cornell</strong> <strong>University</strong>
A few more suggestions…CONCLUSIONS• Emphasize importance <strong>of</strong> properly using equipment• Mechanical changes are easy but staff behaviorsmust be changed in order to really reduce thenumber and severity <strong>of</strong> injuries• Offer more, mandatory training• Create a reward system for attending trainingsessions and using techniques learned• Have random evaluations <strong>of</strong> techniquesIn general, the current situation is acceptable. The lowstaff to patient ratio and higher level <strong>of</strong> physical andmental functioning <strong>of</strong> the patients makes the tasks lessstrenuous.DEA470/670 2003, © <strong>Cornell</strong> <strong>University</strong>
