In The ER: Fatal Overcrowding
Vincent Lam, National Post
I didnt say it quite like that.
I told Mr. A that the largest artery in his body was bleeding into his abdomen, that this carried a fifty percent mortality with surgery; a certainty of death without surgery, and I could not find a vascular surgeon for him.
Both of our hospitals vascular surgeons were operating, we had no Intensive Care beds free to take care of Mr. A after an operation, even if we could get him one, and the provincial emergency transfer service, Criticall, searched desperately but found no available surgeon and bed for my patient in Ontario. The Criticall coordinator told me, Ive got nothing. Youre on your own.
Nowadays we, front-line Emergency Medicine providers, are often on our own with nothing to give a patient. In front of our triage desk, where patients explain why they have come to hospital, there was once one chair. Then two, then five, and now there are ten chairs in two rows, filled with those waiting to be triaged. This is not the waiting room. The waiting room, burst to overflowing, is where people go to endure their pain along with fifteen to thirty other members of the public for six, eight, twelve hours with no medical attention after triage. Next to the triage desk, there are three to six ambulance crews waiting for hours to deliver their orange-wrapped patients. The Toronto District Ambulance Service has announced that this offload delay problem is a crisis. They are frequently unable to respond to emergency calls because they are marooned in hospital ERs.
It would be nice if we could point to one issue, such as ambulance offload delays, or packed ER waiting rooms, and say thats the problem fix that! The reality is not so simple. These problems are only the highly visible tip of the iceberg which is health cares now-dysfunctional lack of capacity. During the past decade, there has been a 40% decrease in inpatient bed funding in Canada. With an aging population that needs increasingly complex care, the result is that hospitals are literally overflowing just check the ambulance parking lot in front of any Canadian hospital.
It goes like this: The ambulances cannot offload, because the ER beds are full. The ER is full, because the ER beds are regularly occupied by admitted patients who are supposed to go to the wards. Across Canada, 10-25% of the wards beds are filled with patients who need to be placed in rehabilitation, nursing homes, or palliative care facilities, but there are no places to send them in the community.
It gets more tricky: Some hospital beds are needed for patients to recover from elective procedures. If these beds are used for emergency admissions, elective procedures are cancelled. When elective procedures are canceled, patients medical problems deteriorate, and they wind up in the ER. Also, the wards are under intense pressure to discharge patients. If they keep patients too long, they prevent other patients from coming to the ward from the ER. If they discharge them too early, the discharged patients quickly become ill again and return to the ER.
Every day in the ER, patients and families are understandably frustrated by long waits, either bearing their pain and indignity stoically, or harassing the ER staff. The ER staff are helpless to assist those who wait politely, and abused by those who shout at them. The never-ending task of explaining ten times per hour why there is such a long delay, why an important test cant be performed yet, or why a patient hasnt had an operation, robs time and energy from delivering health care, and accelerates the burnout and departure of skilled emergency nurses and physicians.
Economic pressures and hospital bed closures are the direct cause of the increasing numbers of patients log-jammed in ERs. Between 1990 and 2000, the number of acute care beds in Canada fell from 4.0 to 3.3 per 1000 citizens, putting us well below the OECD average of 3.8 per 100. New Zealand and Germany both have over twice the number of hospital beds per capita, and we are also bested by France and Australia. In Ontario, with 2.7 beds per 1000 citizens, bed occupancy jumped from 85.6% in 1994/95 to 93% in 1999/2000. Hospitals are forced to target occupancy rates of over 90%. This sounds very efficient, but health care is an enterprise in which demand for vital services fluctuates wildly and unpredictably. Studies have demonstrated that occupancy rates above 85% pose discernible risks to patients, and above 90% a hospital is in a state of regular bed crisis. Running at high occupancy means that most people will be reasonably cared for most of the time, but if Mr. A is bleeding to death and there is no capacity in the system, well you better hope youre not Mr. A.
A convenient political maneuver is to off-load responsibility to the public by saying ERs are crowded because people are going there inappropriately. This is false. The vast majority of ER patients are there out of necessity. Why else would someone wait eight hours to see a doctor? If a fraction of patients use ERs for problems that could be dealt with elsewhere, they do not clog the system. Simple problems are quickly dealt with: a physician treats an ankle sprain in two minutes, or sews up a cut in five minutes, and then the patient leaves the hospital. In contrast, a patient with chest pain requires a bed, a cardiac monitor, an intravenous, complex assessments and treatments, time-consuming tests, multiple electrocardiograms, and a high level of observation for hours or days. Each patient in the ER waiting to go to the ward, results in 2-4 patients per hour being stuck in the waiting room. Meanwhile, to discourage people from seeking care because it is their fault that the system is overcrowded only results in patients not receiving medical care at times when it is crucial for them to receive it. Patients often dont know whether their problems are minor or major thats why we have doctors to sort that out.
Conjuring up the myth of inappropriate use of the system diverts the discussion from the more difficult real issue, which is the lack of systemic inpatient capacity. This is an unattractive political and societal problem, because having more beds means spending more public money, which means collecting more taxes. Over the past fifteen years, inefficiencies have already been tightly wrung out of our health care system by cutting administration, axing extra programs, shifting care to outpatient settings wherever possible, streamlining bulk purchasing of supplies, de-listing services, and merging or closing hospitals. On a percentage of GDP basis, Canada spends just over two thirds of what the US spends, and I might add, still beats the US in life expectancy, infant mortality, and most other standard measures of health outcome. Canadians are getting good value for money. Canadian health care is now lean and sleek, or perhaps bordering on starving and cachectic. At this point, relieving our systems tragic human congestion means creating more bed capacity, which means spending more taxpayer money. Thats your money, and theres no squirming out of it.
When I informed our vascular surgeons that no one in the province would be able to help Mr. A, they rose to the occasion. Somehow, they squeezed Mr. A into an operating room although they were both in the midst of surgeries. With no ICU bed available, Mr. A was cared for after his operation in the surgical recovery room which borrowed and jerry-rigged the resources needed to save his life. A few days later, I heard that he made a good recovery.
This is commendable, but disturbing. Our health care is now reliant upon the improvisational abilities of health care workers, who often lack the basic resources needed to care for patients. This is wrong. With our health care system in a state of constant capacity crisis, some will now find that the line between death and life, between suffering and dignity, is simply whether services are already occupied-to-capacity when they need them.
Mr. A is not unique. Any ER doctor or nurse can tell you about narrow misses, patients almost killed by the ongoing shortage of resources, and who survived by our juggling and conjuring when there was nothing else to do. The same doctors and nurses can tell you, in hushed tones, about patients like Mr. A dying in the ambulances, and in the waiting rooms of our very efficient and cost-effective health care system.
Who would like to be Mr. A?
