It seems miraculous that US Airways Flight 1549 from New York City landed without loss of life in the Hudson River. The Jewish Talmud says, "Expect miracles, but don't count on them." The airplane designers apparently relied on this in their design of key safety features which enabled a skilled airplane crew to land the plane safely. Seven of their life-saving practices reveal life-saving suggestions for hospitals.
1. Captain Chesley Sullenberger III remembered from his training that if a plane has to ditch, it should be done near a vessel. So he landed the plane near a boat that he saw on that stretch of the Hudson. Other boat captains saw the first boat captain head toward the plane, and they followed, rescuing the passengers promptly.
Lesson for hospitals: Train doctors and nurses on what to do in case of errors as rare as needing to ditch a plane in the water.
2.The plane's first officer, Jeffrey Skiles, was in control of the plane at take-off. But as soon as the plane ran into the flock of birds and both engines quit at about the same time, the more experienced Captain Sullenberger announced, "My aircraft," using the standard phrasing and protocol drilled into airline crews during training. "Your aircraft," Mr. Skiles responded. The airline industry explicitly trains pilots how to manage the change of command of the plane, and the appropriate terse ways to communicate that. This hand-off of authority was clear, immediate, and was automatically documented in the black box recorder. Trainers also teach crew members to routinely "say back" oral orders to ensure they have been correctly understood.
Lessons for hospitals: Create ways to hand off responsibility for patients that are clear, immediate, efficient, reliable, and verified.
3. After Captain Sullenberger took command of the plane, he, First Officer Skiles, and the air traffic controller discussed returning to La Guardia Airport, but decided against it. The pilot didn't decide alone; the three people took time to have a brief discussion, even in the midst of their extremely urgent looming disaster. Airlines have long trained pilots to perform such "crew resource management" (often now called "crisis resource management" in healthcare).
Lesson for hospitals: Train your clinicians to quickly, promptly and routinely discuss critical options for treatment, while driving out subordinates' fear that a higher-ranking surgeon or doctor will punish them for speaking up.
4. A passenger in the exit row was able to correctly remove the emergency exit door because he had taken a minute at that time to "readthelaminatedsafetycardofinstructionsintheseatpocketinfrontofyou." The airline had taken the time to prepare instructions for this very rare event of a water landing and place them where they could be snatched and understood promptly.
Lesson for hospitals: Patients are your partners. Help them by placing a laminated card of instructions in patients' rooms on how and when to call a Rapid Response Team. (It's now a state law in Massachusetts, and perhaps other places, for hospitals to have Rapid Response Teams to reply promptly upon the unexpected sudden deterioration in a patient's condition.)
5. After Captain Sullenberger took command of the plane, he set his co-pilot to work at moving through a three-page checklist of procedures for restarting the plane's engines. Note that the detailed checklist had been developed well in advance precisely for this exceedingly rare event. It was in the cockpit, i.e., it was immediately accessible, and didn't require the co-pilot to have memorized the procedures.
In this case, the checklist wasn't helpful, since it was intended for planes in distress at much higher altitudes, which allows for more time to restart the engines.
Lesson for hospitals: Sometimes you'll get lucky, and the patient will live despite your lack of a checklist. But you should, of course, have checklists for handling the most common errors. Expect laws soon to require the checklists.
6. The plane's force at impact would determine how many would live or die. It was critical to slow the plane. The pilots had to lower the flaps (movable devices on the wing) to slow the plane. But the flaps run on hydraulic power, driven by the now-useless bird-stuffed engines. The Airbus A320 has a "ram air turbine," essentially a little propeller, that drops down into the wind automatically in certain conditions, and produces electricity to provide the energy that allowed the crew to lower the flaps. With this automatic backup at work, the crew was able to slow the plane enough to make what felt like a hard landing, rather than a crash.
Lesson for hospitals: You may have generators that come into automatic use when the electricity fails. Perform a Failure Mode Effects Analysis to identify the failures that are most common and life-threatening, and ascertain where you need other automatic backups.
7. The Army Corps of Engineers is now searching the Hudson River for an engine, which may provide evidence on whether the plane really hit the birds. In effect, the government is helping to determine the cause of the accident.
Lesson for hospitals: Outsiders may be willing to help you find the causes of accidents. Let them partner with you.
