'Mock' drills boost child resuscitation skills in 'failing' adult emergency rooms

Following up on a study that found widespread failures in simulated child resuscitation among emergency room staff, a research team from the Johns Hopkins Childrens Center and Duke University Medical Center reports that it doesnt take much more than a mock trauma drill to diagnose the shortcomings and brief refreshers to get ER workers performance sharp again. Their report appears in the November issue of Pediatric Emergency Care.

The investigators note that both studies involved adult ERs in community hospitals and adult trauma centers rather than pediatric ER teams who specialize in child resuscitation. Of the 20 million children injured in the United States each year, only 20 percent end up in specialized pediatric ERs or pediatric trauma centers.

The lesson learned is that improvements in ER trauma resuscitation and other critical care given to children can be seen after brief performance tests and refresher programs, the researchers say.

The bad news is that failures are widespread, but the good news is that fairly simple refreshers based on quick analysis of what isnt working could be really helpful, says lead investigator Elizabeth Hunt, M.D., M.P.H., a critical-care specialist at Hopkins Childrens. Its encouraging to see that in most cases, merely raising a red flag and telling the staff heres what you did wrong and heres how it should be done, helped them see their own shortcomings and do better the next time.

In their report, the research team recalled its 2005 study, which found that one-third of North Carolinas 106 ERs failed in crucial areas while stabilizing a critically injured child during a mock emergency drill. The team then returned to 18 of the 35 ERs, armed with an analysis of what went wrong and refreshed the staffs knowledge on 44 tasks, including ones specific to child resuscitation, such as weight-based dosing of drug treatments, blood sugar assessments and placement of IVs through the bone, a critical alternate route for delivering fluids to children whose veins have constricted due to blood loss or other injury.

In the current study, the team made surprise visits to18 ERs six months later and found that scores on 37 of the 44 tasks improved, and scores on 11 of the most important ones, such as accessing circulation through the bone or performing head examinations, improved significantly.

For example, following the refresher, the number of ERs properly estimating a childs weight nearly doubled; the number of ERs correctly assessing consciousness in a child nearly quadrupled; twice as many ER teams properly started an IV through the bone; more than twice as many ordered the correct antiseizure medications; and more than twice as many correctly prepared a child for transport to CT scanners or operating rooms, a critical time when many problems can occur.

Our findings would seem to offer a practical recipe for running a quick diagnostic test of ER skills related to resuscitating children from catastrophe and improving them, Hunt says.

In situ, or on-location, disaster simulations are already a monthly happening at Hopkins Childrens, where trauma teams rate their own performance and diagnose problems in each other.

Researchers note that some tasks on their list of 44 still need improvement, including assessing for neurological and spine injuries, delivering proper weight-based and timely doses of dextrose to stop life-threatening drops in blood sugar and correctly administering IV fluids. Failures on these tasks can also have catastrophic results, the investigators say, and more research is needed to understand why staff continued to perform poorly. The researchers caution that failures during mock drills do not necessarily reflect performance during a genuine emergency, when trauma teams experience adrenaline surge and ultra-sharp focus on the patient, and actual patients provide constant feedback to the teams actions, prompting more appropriate responses. You cant exactly duplicate an actual trauma, Hunt says.

Trauma is the number-one cause of death in children under 14 years of age.
