Does texting ER wait times affect patient care?

On our recent road trip I was amazed by the number of billboards (from several health care systems and hospitals) advertising texting for emergency room (ER) wait times. My first thought was, “if you can text, how emergent is it?” This was quickly followed by the concern that the option/advertising of texting about wait times might make the ER seem, well, less for acute care and more for convenient care.

Should I be concerned?

There are about 130 million ER visits a year in the United States accounting for 4% of health care spending. The total number of ER visits has ballooned since 1995 when there were 97 million visits. A 30% increase is pretty significant, especially when you realize emergencies have not increased by 30%. Then factor in the fact that the number of emergency departments has declined by 11%.

The math only means one thing, 11% fewer places to go but 30% more visits = longer waits. The average wait time to be seen in an American ER is about 55 minutes, which seems long at first blush (and really long if you have a broken leg or have appendicitis) so it is easy to see why texting to find the shortest wait might be attractive.

But let’s back up a bit. Not everyone who goes to the ER needs (medical speaking) to be seen emergently. According to the CDC this is how visits to the ER break down acuity wise (2010 data):

  • Level 1: Should be seen in < 1 minutes – 1% of visits
  • Level 2: Should be seen in 1-14 minutes – 10% of visits
  • Level 3: Should be seen within 15-60 minutes – 43% of visits
  • Level 4: Should be seen within 61-120 minutes – 33% of visits
  • Level 5: Should be seen within 121 minutes to 24 hours – 7% of visits

(The numbers don’t add up to 100% because 5-6% of ER don’t have a triage system so can’t contribute to the stats this way)

What is most important to know is that 25% of patients presenting to the ER are seen within 15 minutes but 11% meet the criteria of needing to be seen within 15 minutes, so that is good math. Another 42% are seen between 15 minutes and an hour, matching up nicely with the level 3 needs. Basically, ERs are currently doing a good job at what they are designed to do. Care for people who have emergent and urgent needs in a timely fashion. (Of course there are stories of people waiting and dying, but that is typically because they were triaged incorrectly and no one realized how sick they were. That is a different, albeit still serious, issue).

But 40% of people who go to the ER do not medically speaking need immediate care and many could be seen elsewhere. Many health care systems, doctor’s offices, and hospitals have weekend and evening hours as well as injury centers and urgent care clinics for this very purpose. A bleeding diaper rash does need to be seen and an ear infection probably needs treatment and that ankle you twisted pretty badly probably should be evaluated to make sure it’s not a break, but the doctor’s office or an urgent care clinic would do just fine. These are medical issues, but they are not emergent issues. Even if you cut your finger and need stitches an injury clinic and in many cases your primary care doctor is a great option.

Just speaking with a nurse or doctor can help. Many people also just don’t know what can wait. There are many times when my kids were sick that I received invaluable advice from the amazing 24 hour nurse line at the Children’s Hospital in Denver. I didn’t even know there was an acute care clinic until I called the advice line.

Does texting ER wait times affect patient care?

Phone advice and other options for care could probably prevent many unnecessary ER visits. In fact 48% of people who go to the ER do so because their doctor’s office isn’t open and 46% because they had nowhere else to go. This tells us that many people know the ER isn’t the best place, but their options are limited. The answer to that problem seems to be improving access to the needed services, not to offer texting as a work around.

So does advertising about texting increase non-urgent use of the ER? If the wait is short might it give someone the idea of just getting things checked out in the ER instead of waiting until the next day? Will it encourage people to just go to the ER when it’s clearly not emergent (because if you can text, it’s not likely a true emergency) instead of calling to speak with the doctor on call or the advice nurse? And what if you really are emergently sick and instead of heading to the closest ER because the texting service gave you a 40 minute wait there (but in reality you would have been seen much sooner because you are urgently ill), you drive further away for a presumably shorter wait but your condition deteriorates en route? Average wait times are just that, average. A true emergency will (if triaged correctly) almost always have less than a 15 minute wait.

Texting is clearly aimed at non-emergent and urgent patients, people who could probably (and many who should probably) be seen in less acute/more appropriate settings. The cynic in me wonders if this texting option it’s just another way to artificially boost Press Ganey scores (I fear many hospital administrators care less about the quality of care and more about the survey results). I’m all for satisfaction, but if it comes at the expense of sending more non-urgent cases to the ER then it’s a concern. Wouldn’t a better solution for ER wait times be more advice nurses/doctors and after hours clinics?

Just a thought.

    I have never been at an ER where the wait-time was short. That’s probably because ERs in South Africa are generally overflowing all the time. So in our case, probably if people knew how long they would wait to be seen, they might just come in to a regular clinic appointment instead. Which could mean that I wouldn’t have to send twenty people home with little more than “here’s an appointment for our clinic next week” during my 24 hour calls when we are already running around resuscitating critical patients.

    The problem is that all the docs offices say if its an emergency go to the ER. Not everyone knows what an emergency is, or the doc will say we don’t treat emergencies, go to the ER anyway. Urgent cares can do so much or they’ll send you there also.

    The last paragraph sums it up it a nutshell… I no longer consider where I work an “emergency department”.. We are a walk-in clinic that is capable of handling emergencies. And our hospital lives and dies by our Press Ganey’s. Provider’s PAY is based on it.
    If the insurance companies and government welfare offices ever woke up and decided to base what they pay hospitals for EMERGENCY visits based on whether it was actually an emergency or not, we are screwed.
