The study shows that carefully written nurse-driven protocols targeted at specific patient groups can result in improved time to test or medication, and in some cases, cut length of stay in the ER.
Implementing procedures where nurses start the diagnosis or treatment before patients are treated by a physician or nurse practitioner have been suggested as a possible way to improve the flow of patients in the emergency room (ER).
The new Canadian study, published in the Annals of Emergency Medicine, describes how nurse-driven protocols cut ER lengths of stay for patients with fever, chest pain, hip fractures, and vaginal bleeding during pregnancy.
Lead author Matthew Douma, clinical nurse educator at Royal Alexandra Hospital in Edmonton, Alberta, says:
"Nurse-driven protocols are not an ideal solution, but a stop-gap measure to deal with the enormous problem of long wait times in emergency departments especially for patients with complex problems."
Protocols cut ER time in busy, inner-city hospital
For their study, Douma and colleagues carried out a controlled evaluation of six nurse-initiated protocols in a busy, crowded, inner-city emergency room.
They measured a number of outcomes, including length of stay in the ER, time to diagnostic test, time to treatment, and time to consultation.
The results showed that nurse-driven protocols:
- Reduced the median time taken to administer acetaminophen to emergency patients with pain or fever by over 3 hours (186 minutes)
- Decreased average time to troponin testing for emergency patients with chest pain suspected to be heart attack by 79 minutes
- Cut average length of stay for patients with suspected hip fractures and patients with vaginal bleeding during pregnancy by nearly 4 hours (224 and 232 minutes, respectively).
"Given the long waits many emergency patients endure prior to treatment of pain," says Douma, "the acetaminophen protocol was a quick win."
Need for 'broad and creative strategies' to cut ER time
The researchers conclude that implementing carefully written nurse-driven protocols targeted at specific patient groups can result in improved time to test or medication, and in some cases, cut length of stay in the ER.
They also note that, "A cooperative and collaborative interdisciplinary group is essential to success."
According to the Centers for Disease Control and Prevention (CDC), around one in five American adults visited the ER one or more times in 2014, the most recent year for which full data is available.
In 2011, there were nearly 136.3 million visits to the ER in the United States, and 27 percent of patients were seen in under 15 minutes.
A number of approaches are being tried and used to improve patient flow through the ER. These include: extending the chain, decreasing and smoothing variation, matching capacity to demand, scheduling the discharge, and pull systems.
An example of a pull system is the "Be a Bed Ahead" scheme of pulling patients from the ER to the inpatient unit.
"Emergency department crowding will continue to require broad and creative strategies to ensure timely care to our patients."
