It was over a quarter of a century ago that I first started talking about "the missing statistic"--those people who die from complications from their hospital visit, but not during the visit itself. If someone is treated for heart problems at a hospital, for example, and is sent home only to die later at home as a result of what happened in the hospital, it doesn't count against the hospital's record for treating the disease--even if the patient dies in the ambulance on their way back to the hospital, as long as they don't actually die in the hospital itself. This means that there are many more people dying as a result of their hospital visits than tally in the statistical sheets.
Over the last few years, there's been some attempt to address this issue, or at least a subset of it--those who are treated for a disease and sent home, only to be readmitted to the hospital at a later date as a result of their original visit, even if not for the original cause. If you die at home, you're still among the great uncounted. But now at least, if you make it back in, it counts. It may not sound like much, but it actually is since it at least acknowledges the connection between the original visit and the readmission, even if the reason for readmission might seem initially unrelated. This is a big deal since it identifies yet another set of dangers related to hospital stays that was previous ignored--except by those who actually died as a result. A bit later we'll explore the entire panoply of dangers typically found in hospitals, but for now, we'll focus on this latest discovery, which is called post-hospital syndrome.
The essence of post-hospital syndrome is very simple. A hospital stay, especially if traumatic, can make some patients susceptible to new health problems, unrelated to the initial problem. For example, nearly one fifth of Medicare patients discharged from a hospital -- approximately 2.6 million seniors -- have an acute medical problem within the subsequent 30 days that necessitates another hospitalization.1 These recently discharged patients have heightened risks for a whole range of conditions, many of which, as mentioned a moment ago, appear to have little in common with the initial diagnosis. For example, among patients admitted for treatment of heart failure, pneumonia, or chronic obstructive pulmonary disease (COPD), the cause of readmission is the same for only 37%, 29%, and 36%, respectively. The causes of readmission, regardless of the original admitting diagnosis, commonly include heart failure, pneumonia, COPD (which are the same as the three original admitting conditions, although not always matched up)--but also, infection, gastrointestinal conditions, mental illness, metabolic derangements, and trauma. (As we will discuss later, the same principle applies not just to seniors but also to the very young and, most likely, all categories of patients to varying degrees.)
Professor Harlan Krumholz examined both this study and the concept of seemingly unrelated readmissions in a perspective article published in the New England Journal of Medicine in January of this year.2 He was also part of a research team that published the results of their study of the same issue in the Journal of the American Medical Association that was released around the same time.3 Professor Krumholz is a cardiologist and Professor of Medicine and Epidemiology and Public Health at the Yale University School of Medicine. The original intent of Professor Krumholz and his research team was to focus on the hospital admissions rate of patients with cardiovascular disease; but after looking at what was happening to patients after their release from the hospital, they began to see something unexpected. They named this phenomenon: post-hospital syndrome--a temporary period of increased vulnerability to all sorts of risks, from falls to heart attacks. According to Professor Krumholz, patients initially hospitalized for pneumonia, for example, might become so weakened after a hospital stay that when they were back home, they'd fall and fracture a bone. Historically, these would be recorded as two isolated, independent incidents, when in truth they are anything but.
As the research team stated, "They [the patients] come into the hospital with one thing, but they leave with another. Maybe what is going on is that people, through the hospitalization, are acquiring a new condition, something that makes them susceptible to a whole range of problems." According to the researchers' analysis of more than 3 million hospitalizations, among readmitted patients, 90% of those initially diagnosed with a heart attack came back with a different problem. So did 65% of the heart failure patients and 78% of the pneumonia patients. According to Krumholz and his fellow researchers, this period of risk is the result of the cumulative stressors on patients during hospitalization that can increase their susceptibility to adverse health events. These include:
It's important to understand that post-hospital syndrome is not about medical errors and hospital-acquired infections, both of which can jeopardize patients' lives. Those are tallied separately--again assuming the patient doesn't die outside of the hospital. What we're talking about here is not poor hospital care or medical mistakes, but "the routine difficulties of being a patient," says Krumholz.
Krumholz goes on to say that hospitals should try to address these issues, both before patients leave the hospital and in follow-up visits. In some cases, he says, it may be better for a patient to get a good block of sleep, rather than be awakened at 3 a.m. in order to administer a medication at the appropriate interval. In analyzing the reasons why patients are readmitted, he says, "we haven't thought enough about the hospitalization, and how to make it less toxic, more healing and more soothing." Professor Krumholz also recommends teaching patients about post-hospital syndrome and taking the time to warn them about the implications of the associated mental and physical impairment. Patients should be encouraged to find someone to help them with post-discharge instructions, to resume daily activities, and to be safe by recognizing their risk for falls and accidents.
The problem for the medical community is that the further away from the hospital discharge you go, the harder it is to connect the dots. That's why Krumholz and his team stuck with 30 days. But that's not to say there aren't more drawn out connections.
For example: according to a study performed at Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) in Boston and just presented last month at the American Society of Pediatric Hematology Oncology in Miami, nearly two-thirds of children receiving stem cell transplants returned to the hospital within six months for treatment of unexplained fevers, infections, or other problems.5 Children who received donor cells were twice as likely to be readmitted as children who received their own stem cells. The key point, as Leslie E. Lehmann, MD, clinical director of pediatric stem cell transplantation at DF/CHCC, pointed out is that, "No one had ever looked at these data in children."
In other words, until this study made the connection, the original treatment in the hospital and the subsequent readmission appeared to be unrelated. The dots were not connected.
And then there was the British Medical Journal, Quality & Safety observational study published last year that found a direct link between nursing staff ratios and hospital readmissions for children with common medical and surgical conditions.6 Specifically, the study concluded that children with common conditions treated in hospitals in which nurses care for fewer patients each are significantly less likely to experience readmission between 15 and 30 days after discharge. How less likely? The study found that children who are treated in hospitals that meet the current California mandated staffing ratio of four or fewer pediatric patients per nurse have a 63% reduced risk of readmission.
Over the years, we have discussed many of the reasons you might want to avoid checking into a hospital. As it turns out, there are many dangers (dots) that exist in isolation and never get connected in terms of the total risk you face. It's important to understand that the whole is greater than the sum of its parts. When looked at one at a time, the risk factors at first seem almost manageable. It's not until you look at them in their totality that you realize how great a risk you face. Some of these risks that have not already been discussed include:
But these things we already knew. What the new studies tell us, though, is that it's even worse than the medical community thought. It turns out that you can take all the numbers cited above and ramp them up because a lot of deaths have not been getting connected to what actually caused them--the original hospital stay. And, as I mentioned at the top of the newsletter, it's even worse than the new studies suggest since they're only talking about those people who are readmitted to the hospital and thus get included in the statistics. What about those who develop a problem as a result of their hospital stay and die at home? As I discussed previously, no one's connecting their deaths to their hospital stays. How many are we talking about? It's more than zero, and whatever the number is, it's not included in the hospitals' statistics.
Well, the first and most obvious thing is to start correcting some of those things that now lead to post-hospital syndrome…and ultimately to hospital readmissions and death. You can start with the things Krumholz points out.
But it doesn't stop there.
Hospitals need to adopt common reporting formats and definitions so that data is easily understood as patients enter different facilities. Surprisingly, that is not yet the case, which means doctors in one facility may not understand what has been done for a patient in a previous facility…and that can be deadly.
Patients need better guidance when being discharged and better follow up once they are home. You're pretty much handing out a death sentence to a patient when you quickly give instructions to a drug addled, exhausted, confused patient just before you discharge them and don't follow up with them shortly after they get home to see if they actually understood what they need to do. And seniors, if they do not have a family member working as an advocate for them, need special attention both when being discharged and when making sure they are following proper protocols once home. Many are fully capable of taking care of themselves, but many are not.
And hospitals need to adopt checklists for all procedures, especially surgical procedures--much like a pilot's checklist before taking off in a plane--to make sure everything is A-OK before commencing.8
Don't be afraid of hospitals and don't avoid them unnecessarily. On the other hand, recognize the dangers and think of hospitals as a last resort. If you can avoid checking into one, you avoid exposure to a huge amount of collateral risk. If you can be treated on an outpatient basis, in most cases, that's a better way to go. If you can avoid taking pharmaceutical drugs and deal with your condition using natural remedies and dietary modifications and lifestyle changes, then you're miles ahead of the game doing so. (Think Baseline of Health.) On the other hand, if you can't control your condition using natural means, then don't be a martyr. Use the pharmaceutical drugs, but:
And if your doctor won't work with you, find another doctor who will. Sometimes hospitals are necessary. If you're in a major automobile accident, you want a hospital, not a chiropractor's office (at least initially). But just because hospitals are sometimes necessary doesn't mean that they are ever completely safe. Know the risks and protect yourself as best you can. Don't become a hidden statistic.
