Avoid the Hospital in July

Why? New doctors and nurses report to work for the first time

En español l July is upon us so you might want to avoid the hospital if at all possible.

Why? On or around July 1, newly graduated interns, residents, nurses and other new health care workers first report to work at many of the nation's hospitals, eager to start practicing medicine — on you. No surprise then, that quality of care in hospitals plummets, and medical errors increase, during the following month.

In the most recent study on the so-called "July Effect" — published earlier this year in the Journal of Neurosurgery: Spine — Mayo Clinic researchers analyzed outcomes of 1 million spinal surgery patients admitted to 1,700 hospitals across the country during July over an eight-year period. Roughly half got surgery at a teaching hospital with newly minted medical students, while the others were treated at nonteaching facilities.

Their conclusion: Patients at teaching hospitals fared only slightly worse — a "negligible effect," wrote the researchers — on criteria such as in-hospital death rates and negative reactions to implanted devices.

"But they also found that compared to others, July patients had higher rates of discharge to other long-term care facilities, as well as post-operative infection and surgical stitches failing," notes David Sherer, M.D., a practicing anesthesiologist and past director of risk management for a large insurance provider, who wrote the book Dr. David Sherer's Hospital Survival Guide.

"Those are three significant outcomes that certainly don't convince me the July Effect doesn't exist," adds Sherer, who was not involved in the Mayo analysis. "And the fact that researchers keep looking into this, asking, 'Is it real?' makes you believe that there's good reason to believe it is. Based on my own experience and speaking with other doctors and patients, I'm convinced the July Effect exists."

Which hospitals are riskiest?

When analyzing the research, it turns out "where" may be even more important than "when." Most studies indicating patients problems during July find higher rates at teaching hospitals — those typically affiliated with a medical school where newly minted medical students get their first on-the-job training.

You may get more personal attention, but the skill level isn't there, explains Sherer. "You have newcomers arriving at hospitals — often placed in a sink-or-swim situation — and they don't know where anything is or how anything is done."

Although as a group these newbies are universally supervised, "from day one, residents are writing medication orders and doing certain procedures and diagnostic tests with relatively little direct supervision, so there's always an opportunity for something to slip through the safety net," adds Christopher Landrigan, M.D., who teaches at Harvard Medical School and oversees residents at Boston Children's Hospital.

That's not to say that midsummer is the only time for potential problems. After all, some 100,000 Americans die from hospital medical errors each year — thousands every month. "But there is good evidence that errors are somewhat more common when residents first begin to work," notes Landrigan.

One study, published three years ago in the Journal of General Internal Medicine, reviewed 62 million death certificates issued between 1979 and 2006 and found that fatal medication errors consistently spiked in July by about 10 percent in U.S. counties with many teaching hospitals — and then subsided in August to levels on par with other months. Yet there was no measurable increase in counties with facilities that didn't employ residents, such as community hospitals.

"We were looking for all causes of death occurring in hospitals," explained study leader David P. Phillips of the University of California, San Diego, "and found no increase in death from surgical errors, hospital-acquired infection or other causes in any type of facility — only in fatal medication errors at teaching hospitals."

Another study, published in 2011 in the Annals of Internal Medicine, also suggests it's best to avoid teaching hospitals during July.

After reviewing data from 39 previous studies, it found death rates increased 4 to 12 percent — and patients endured longer hospital stays and more time in surgery — during July, when teaching hospitals "experience a massive exodus of highly experienced physician trainees" as rookies take their place, said study lead John Q. Young, M.D., of the University of California, San Francisco.

How to better avoid potential problems

1. Bring your own health records (including a Personal Medication Record). To reduce the risk of dangerous drug interactions, bring several copies of a list of everything you currently take — prescriptions as well as over-the-counter products, vitamins and herbal supplements — with their correct spelling, specific dosages and the reason for their use.

2. Ask a friend, relative or other health advocate to stay with you. Like you, advocates should also ask "why" when a drug or procedure is given. This will help ensure your day-to-day care is correct and provide an extra set of eyes and ears to understand the "big plan" of your treatment.

3. To lessen the chance of mix-ups, state your name to anyone providing you with care.

4. Know the name of the doctor who is ultimately in charge of your care. This lead provider should be (and usually is) an experienced primary attending physician — not a resident or intern — although that "primary" may change throughout your stay.
