MRSA research round-up: hospitals, vitamins, pets

By Leave a Comment

Because I’ve been so behind, there’s so much to cover! So let’s dive in:

In today’s Archives of Surgery, researchers from Seattle’s Harborview Medical Center report that one simple addition to the routine of caring for trauma patients made a significant difference to the patients’ likelihood of acquiring a hospital-associated infection: bathing them once a day with the antiseptic chlorhexidine (in an impregnated wipe). Patients who were bathed with the antiseptic wipe, compared with patients wiped down with an inert solution, had one-fourth the likelihood of developing a catheter-related bloodstream infection and one-third the likelihood of ventilator-associated MRSA pneumonia. Cite: Evans HL et al. Effect of Chlorhexidine Whole-Body Bathing on Hospital-Acquired Infections Among Trauma Patients. Arch Surg. 2010;145(3):240-246.

How important are hospital-acquired infections? Here’s a piece of research from a few weeks ago that I sadly failed to blog at the time: Just two categories of HAIs, sepsis and pneumonia, account for 48,000 deaths and $8.1 billion in health care costs in a single year. Writing in the Archives of Internal Medicine, researchers from the nonprofit project Extending the Cure analyzed 69 million hospital-discharge records issued in 40 states between 1998 and 2006. Hospital charges and number of days that patients had to stay in the hospital were 40% higher because of those infections, many of which are caused by MRSA — and all of which are completely preventable. Cite: Eber, MR et al. Clinical and Economic Outcomes Attributable to Health care-Associated Sepsis and Pneumonia. Arch Intern Med. 2010; 170(4): 347-53.

 What else could reduce the rate of MRSA infections? How about Vitamin D? South Carolina scientists analyze data from the NHANES (National Health and Nutrition Examination Survey 2001-2004), a massive database overseen by the CDC, and find an association between low blood levels of Vit. D and the likelihood of MRSA colonization. More than 28% of the population is Vitamin D deficient. MRSA colonization is increasing in the US. Can giving Vit. D decrease MRSA carriage? More research needed. Cite: Matheson EM et al. Vitamin D and methicillin-resistant Staphylococcus aureus nasal carriage. Scand J Infect Dis. 2010 Mar 8. [Epub ahead of print]

And finally: Who else carries MRSA? Some unlucky pet owners have found that animals can harbor human strains, long enough at least to pass the strain back to a human whose colonization has been cleared. So it makes sense to ask whether humans who spend time with pets are carrying the bug. Last month’s Veterinary Surgery reports that the answer is Yes. Veterinarians are carrying MRSA in very significant numbers: 17% of vets and 18% of vet technicians at an international veterinary symposium held in San Diego in 2008. Cite: Burstiner, LC et al. Methicillin-Resistant Staphylococcus aureus Colonization in Personnel Attending a Veterinary Surgery Conference. Vet Surg. 2010 Feb;39(2):150-7.

Recommending: Consumer Reports on hospital infections

By Leave a Comment

Constant readers, the magazine Consumer Reports has done an extended, state-by-state analysis of which hospitals do well, or very badly, in preventing one important category of infections: central line-associated bloodstream infections, or CLABSIs (pronounced klab-sees). It’s a comprehensive package in easily understandable language. It’s based on the state reporting data that some activists have managed to persuade states to disclose, along with another set of data that some hospitals voluntarily tender to the nonprofit firm The Leapfrog Group.

From the Consumer Reports story:

Poorly performing hospitals included some major teaching institutions. For instance, New York University Langone Medical Center in New York City reported 39 infections in 10,119 central-line days in 2008, roughly twice the national average for its mix of ICUs. The University of Virginia Medical Center in Charlottesville didn’t do much better, reporting 77 infections in 18,572 days for the 15 months ending in September 2009, also about two times the national average.

More encouragingly, nationwide, we counted 105 hospitals whose most recent public reports tallied zero central-line infections. They ranged from modest rural institutions to urban giants such as the University of Pittsburgh Medical Center Presbyterian hospital, which reported no infections among patients who were on central lines a total of 13,596 days in 2008.

It’s well worth reading, and checking to see whether a hospital you may have used, or may be considering using, is on the good list or the bad list. Take a look.

Bad news from California: MRSA quadrupled

By Leave a Comment

Via the Fresno Business Journal and the Torrance Daily Breeze come reports of a new study by California’s Office of Statewide Health Planning and Development: Known MRSA cases in the state’s hospitals increased four-fold between 1999 and 2007, from 13,000 to 52,000 cases per year.

From the Torrance paper:

The good news is that the percentage of people who die of MRSA has decreased, from about 35 percent in 1999 to 24 percent in 2007. The raw number of deaths, however, more than doubled to about 12,500. (Byline: Melissa Evans)

From the Fresno paper (no byline):

Fresno, Kings, Madera and Tulare counties were among 38 counties in California that had 61 to 80% of patients with staph infections.
Only one county, Sierra, fared worse. Eight-one to 100% of patients ended up with staph infections in that county’s hospitals.
In 1999, Kings and Madera counties were in the 0 to 20% range and Fresno and Tulare counties were in the 21 to 40% range.

100%??



My guest-post elsewhere: Bad news on hospital error rates

By Leave a Comment

It’s been 10 years since the publication of the pathbreaking Institute of Medicine report, “To Err is Human,” which for the first time focused policy attention on medical errors. The Interdisciplinary Nursing Quality Research Initiative has been running a two-week special series of posts to mark the occasion, and they very kindly asked me to contribute.

Here’s a link to my guest-post, “Hospital Error Rates — Still a Long Way To Go,” looking at a recent paper and editorial in the Journal of the American Medical Association that reported very discouraging results in rates of infections in ICUs worldwide. (And, umm, yes, that is what I look like.)

While you’re there, please take a look also at another guest post by my good friend Nancy Shute, former staff writer and now blogger for US News & World Report, who discusses the difficulty of speaking up as a patient, based on her own experience in the hospital last summer. It’s very worth a read.

One more set of recommendations

By Leave a Comment

… and then next week I’ll be back to analyzing the medical literature: A stack of interesting new journal articles is threatening to topple and bury my computer.

For the moment, though:

First, the Hearst newspapers chain has conducted a nationwide investigation into medical errors that should be required reading for anyone who wonders why hospitals can’t do a better job controlling hospital-acquired infections. It is a 7-part series focusing on the 5 states (New York, Texas, California, Connecticut, Washington) where there are Hearst papers, and hosted on the site of the San Francisco Chronicle. The introductory article says:

Ten years ago, a highly publicized federal report called the death toll shocking and challenged the medical community to cut it in half — within five years.
Instead, federal analysts believe the rate of medical error is actually increasing.
A national investigation by Hearst Newspapers found that the medical community, the federal government and most states have overwhelmingly failed to take the effective steps outlined in the report a decade ago.
… in five states served by Hearst newspapers — New York, California, Texas, Washington and Connecticut — only 20 percent of some 1,434 hospitals surveyed are participating in two national safety campaigns begun in recent years.
Also, a detailed safety analysis prepared for Hearst Newspapers examined discharge records from 1,832 medical facilities in four of those states. It found major deficiencies in patient data states collect from hospitals, yet still found that a minimum of 16 percent of hospitals had at least one death from common procedures gone awry — and some had more than a dozen. (Byline: Cathleen F. Crowley and Eric Nalder)

From that opening statement, the investigation goes on to explore many patient stories that individually are tragedies and collectively — as we here know all to well — are a scandal.

There is just one notable MRSA story in the mix, the death of a retired hospital president who contracted the bug in his own hospital. But they are all worth reading.

Second, an executive and apparently new writer named David Goldhill has written for The Atlantic a passionate and well-thought out piece on his father’s death from a hospital-acquired infection and on what needs to change for such deaths to never happen again. “My survivor’s grief has taken the form of an obsession with our health-care system,” he writes:

My dad became a statistic—merely one of the roughly 100,000 Americans whose deaths are caused or influenced by infections picked up in hospitals. One hundred thousand deaths: more than double the number of people killed in car crashes, five times the number killed in homicides, 20 times the total number of our armed forces killed in Iraq and Afghanistan. Another victim in a building American tragedy.

You may not agree with his conclusions, but it is worth reading through to the end to experience how one intelligent citizen from outside health care understands and attempts to re-think our broken system.

Infections rise, but hospital budgets – and infection control – shrink

By Leave a Comment

Bad news from the Association of Professionals in Infection Control and Epidemiology (APIC): In a survey of almost 2,000 of their 12,000 members, 41% say that their hospitals’ infection-prevention budgets have been cut due to the down economy.

According to the survey, conducted March 2009 and released Tuesday morning:

Three-quarters of those whose budgets were cut experienced decreases for the necessary education that trains healthcare personnel in preventing the transmission of healthcare-associated infections (HAIs) such as MRSA and C. difficile.
Half saw reductions in overall budgets for infection prevention, including money for technology, staff, education, products, equipment and updated resources.
Nearly 40 percent had layoffs or reduced hours, and a third experienced hiring freezes.

As we know here, there are (by CDC estimate) 1.7 million hospital-acquired infections and 99,000 deaths as a result of them, each year. These are numbers we are supposed to be trying to reduce. That is going to be less likely if less money flows toward what may already be an underfunded goal:

A third of survey respondents say that cuts in staffing and resources have reduced their capacity to focus on infection prevention activities.
A quarter of respondents have had to reduce surveillance activities to detect, track and monitor HAIs.

Disturbingly, at a time when electronic health records are such an important part of the health-reform debate, “Only one in five respondents have data-mining programs – electronic surveillance systems that allow infection preventionists to identify and investigate potential infections in real time.” (APIC press release)

The full report is here.

10 years but little progress on patient safety

By Leave a Comment

Constant readers, I’ve been away for a week — trying to get my breath back now that the chaos of the novel H1N1/swine flu is diminishing — and so I’ve missed a lot of news. Over this week, I’ll try to catch you up on it.

First up: Some of you know that, 10 years ago, the nonpartisan, Congressionally-chartered Institute of Medicine (IOM) published a groundbreaking report called To Err is Human (html here, pdf here) that jump-started examination of medical quality in the United States. That report said:

Health care in the United States is not as safe as it should be–and can be. At least 44,000 people, and perhaps as many as 98,000 people, die in hospitals each year as a result of medical errors that could have been prevented…
Preventable medical errors in hospitals exceed attributable deaths to such feared threats as motor-vehicle wrecks, breast cancer, and AIDS. …
Beyond their cost in human lives, preventable medical errors exact other significant tolls. They have been estimated to result in total costs (including the expense of additional care necessitated by the errors, lost income and household productivity, and disability) of between $17 billion and $29 billion per year in hospitals nationwide. (To Err is Human, executive summary)

The report prompted a huge groundswell of legislative interest and patient advocacy that led, years later, to the successful passage of state laws insisting on public reporting of hospital infections and more recently on disclosure of hospital-acquired MRSA.

And yet: Despite all that scrutiny and activism, we are nowhere near as far as we should be in reducing medical errors. Just in the area of hospital infections, which is our greatest interest here, there is not mandatory reporting in all states, and there is no nationwide reporting.

So says the Safe Patient Project of Consumers Union, which has produced an update to the IOM report called To Err is Human — To Delay is Deadly. They conclude:

Ten years later, we don’t know if we’ve made any real progress, and efforts to reduce the harm caused by our medical care system are few and fragmented. With little transparency and no public reporting (except where hard fought state laws now require public reporting of hospital infections), scarce data does not paint a picture of real progress.
Based on our review of the scant evidence, we believe that preventable medical harm still accounts for more than 100,000 deaths each year — a million lives over the past decade. This statistic by all logic is conservative. For example, the Centers for Disease Control and Prevention (CDC) estimates that hospital-acquired infections alone kill 99,000 people each year.

The project finds that many of the reforms recommended by the IOM in 1999 have not been created:

  • Few hospitals have adopted well-known systems to prevent medication errors and the FDA rarely intervenes.While the FDA reviews new drug names for potential confusion, it rarely requires name changes of existing drugs despite high levels of documented confusion among drugs, which can result in dangerous medication errors. Computerized prescribing and dispensing systems have not been widely adopted by hospitals or doctors, despite evidence that they make patients safer.
  • A national system of accountability through transparency as recommended by the IOM has not been created. While 26 states now require public reporting of some hospital-acquired infections, the medical error reporting currently in place fails to create external pressure for change. In most cases hospital-specific information is confidential and under-reporting of errors is not curbed by systematic validation of the reported data.
  • No national entity has been empowered to coordinate and track patient safety improvements.Ten years after To Err is Human, we have no national entity comprehensively tracking patient safety events or progress in reducing medical harm and we are unable to tell if we are any better off than we were a decade ago. While the federal Agency for Healthcare Research and Quality attempts to monitor progress on patient safety, its efforts fall short of what is needed.
  • Doctors and other health professionals are not expected to demonstrate competency.There has been some piecemeal action on patient safety by peers and purchasers, but there is no evidence that physicians, nurses, and other health care providers are any more competent in patient safety practices than they were ten years ago.

The entire report is well worth reading. Its lamentable but well-supported conclusion:

We give the country a failing grade on progress on select recommendations we believe necessary to create a health-care system free of preventable medical harm.


How hospitals are like cockpits

By Leave a Comment

We’ve talked a couple of times about the growing push for checklists in surgery and elsewhere in hospitals, promoted by Hopkins professor and MacArthur “genius” grant-winner Dr. Peter Provonost and modeled on the use of checklists in aviation. (This stuff interests me not just because it offers so much promise for MRSA reduction but because, as constant readers will remember, I am a pilot and am married to an avionics engineer.)

Provonost and colleagues have a very interesting piece in the current Health Affairs that takes another aviation concept — the Commercial Aviation Safety Team (CAST) — and applies it to medical errors. CAST is a public-private partnership from across the aviation spectrum — government, airlines, labor, manfacturers — that came together in the wake of several terrible accidents to do system-wide analyses of fail points. Provonost proposes that health care could vastly reduce errors by implementing a CAST model.

An inside look at combating HAIs

By Leave a Comment

I’ve been moving my RSS feeds over to a new reader and so am behind in reading things. That’s my lame excuse for not noticing an excellent story in the Washington Post Tuesday, a first-person account tracing the “conversion” of one skeptical physician to the cause of reducing hospital infections.

The story was highlighted at the New Health Dialogue, a must-read health-reform blog, by my friend and former fellow Kaiser fellow, Joanne Kenen.

HAI money in the stimulus bill

By Leave a Comment

Constant readers, for those of you who are following the back-and-forth over the economic stimulus bill, I wanted to let you know that the Association of Professionals in Infection Control (APIC) is saying that the compromise may cut money for state programs to reduce hospital-associated infections.

Here is APIC’s alert:

ACT NOW TO PRESERVE HAI AND PUBLIC HEALTH FUNDING IN STIMULUS BILL

Your urgent action is needed now to preserve public health funding related to HAIs in the stimulus bill pending in Congress.
The stimulus bill passed by the House of Representatives includes $3 billion in funding for overall public health, prevention and wellness programs. Part of this funding includes $150 million for carrying out activities to implement a national action plan to prevent healthcare-associated infections, $50 million of which would be provided to states to implement HAI reduction strategies.
Because of the fast-moving action on this legislation, and the fact that an agreement has been reached to remove prevention and wellness from the Senate stimulus bill, your Members of Congress need to hear from you today as the House and Senate prepare to confer over a final version of the bill. We need them to support the House-passed provisions for public health, prevention and wellness and the HAI language in the stimulus bill (the American Recovery and Reinvestment Act of 2009).

I apologize that, being deep in book production, I don’t know the details of the HAI-reduction programs they are talking about, whether it means support for new mandatory reporting programs or some other thing. (I’ll ask some of the HAI-focused organizations to weigh in back-channel if they can.)

But if you are concerned about the recent new initiatives in various states to report, track and control HAIs, this is probably worth looking at.
