Goodbye waiting room

No Comments
To beat the waiting room gridlock, rethink your entrance strategy

You’ve just started working the 7a – 7p shift in your ED and you get the rundown from the overnight physician and the charge nurse on duty. It’s a typical morning, but you expect the chaos to really begin around lunchtime as it always does. Sure enough, by 1pm, the ED is bustling and every time you turn around, there is another patient coming in from the waiting room.
Are you surprised to see that these patients who have been brought into the ED to be evaluated come with a nasty look of frustration and an attitude to match? When subjected to unnecessary delays that relate to ED front end intake processes, patients can be fuming and the worst part is, you may spend a significant portion of your shift “catching up” to the constant influx of patients.
In many cases this “lunchtime rush” actually traces back to delays related to the ED front end processes that started a couple of hours before and will impede patient flow for hours afterwards. Queuing theory helps to explain why this happens.

Minding Your Ps and Qs (Patients and Queues)

Queuing theory is the mathematical study of waiting lines, and looks at variables such as the arrival rate of customers and the rate at which they can be served. If the arrival rate is greater than the service rate, a queue (waiting line) will form. Let’s say a triage exam takes an average of 8 minutes to complete and there is a queue of 5 patients. The unlucky patient who is at the end of that queue will wait about 40 minutes just to get to triage (unless they balk the queue and leave without being seen). So, even if they received a full registration taking 10 minutes and then wait another 10 to be brought into the ED, it will be at least 1 hour of waiting before they see the physician!

ED Front End Improvement Practices

However, there are several practices which can be implemented to reduce or eliminate front end bottlenecks in your ED that will minimize arrival to bed placement time, satisfy your patients and create a manageable stream of patients into the ED. Some require an investment in staffing or equipment and others require no investment at all as they simply represent process redesign. The following are some of these practices and pros and cons of each:

Computerized Kiosk Sign In

Upon arrival, patients enter their name, date of birth, age and the reason they have come to the ED in a computer terminal kiosk. This information interfaces with the electronic tracking system so the triage nurse knows the number of patients in the waiting room that have to be triaged and some background information.
Pros: Helps the triage nurse manage the number of waiting patients and those in the ED to be aware of what the waiting room looks like.
Cons: Language barriers, computer illiteracy and physical/emotional state of patients may prevent them from accurately completing the form or using it at all.


Demographic information is collected from individuals in the community in advance from to create medical records for a potential ED visit in the future. If/when they arrive to the ED, most of the registration is already completed.
Pros: Eliminates much of the time spent registering patients prior to going to an ED bed. Excellent marketing tactic to increase ED volume.
Cons: Requires substantial investment in set up/management costs as well as planning and coordination with hospital marketing department.
Quick Registration
Minimum amount of information needed from patients (name, date of birth, sex, social security number, reason for ED visit) to create a hospital account is collected during registration. Bedside registration occurs later in the ED visit to collect the remaining information (i.e. insurance).
Pros: Reduces registration cycle times and allows labs and diagnostics to be ordered directly after, due to creation of medical record number.
Cons: Requires consistent training across registration staff and possible modification of registration system to support this function.


Dedicated registrar staff located at walk in entrance who conducts a quick registration (see above) upon arrival.
Pros: Allows standing triage protocols to be executed, due to creation of medical record number. Greeter can provide other information and assistance to arriving patients which can improve patient satisfaction.
Cons: Requires additional investment for staffing and computer and possibly for recongifuration of waiting room.

Physician/PA in Triage

Physician or PA placed in triage to quickly begin evaluation/treatment of patients.
Pros: Large patient satisfier with quick provider contact. Rapid treatment and disposition of low acuity patients

Cons: Unproven model which can compromise and complicate the triage process and create friction with nursing staff. Additional provider staffing costs.
The “Waitless” ED

Waiting room chairs are for family members as the patient has a quick registration upon arrival and is brought directly to a bed afterwards.
Pros: Expedited arrival to bed time and tremendous patient satisfaction initiative.
Cons: Requires significant planning, process redesign and financial investment to ensure effective processes and appropriate ED bed and staffing capacity exist.

From Here to Where?

Unsure of which strategies are best for your emergency department? Here are some starting points:
Determine the waiting room bottlenecks. Assess your front end operation to determine in which queue patients are waiting the longest: triage, registration or bringing patients to a bed. Find out during what time of day each of these queues begin to develop and when they attain maximum values.
How big is too big? In order to streamline the front end process and minimize arrival to bed time, those staff performing the triage, registration and charge function need to be aware of their respective patient queues and when they exceed their ability to manage them. Once these queues reach this threshold, processes should be in place to identify additional help (i.e. double triage rooms, pulling a registrar from another area) in order to decrease the queue length.
So the next time you find yourself caught up in the midday crunch in the ED, imagine what it would be like to experience patient flow with manageable constant arrivals as opposed to inconsistent boluses of patient caravanning from the waiting room. Adoption of one or more of the aforementioned practices may help achieve this and transform your waiting room into simply an “arrival room”.
