These "central line-associated" infections - along with a less serious, but more common variety that arises after the insertion of a urinary catheter - were once seen as an inevitable consequence of being in the hospital. Now the goal is prevention, amid evidence that a mix of common-sense sanitary measures can make a difference.
An Inquirer analysis of data from intensive-care patients on Medicare suggests that area hospitals are making progress.
Of the 42 facilities for which data were available, 11, including Cooper, did better than predicted at preventing infections related to central lines. These widely used plastic tubes are inserted into a large vein, typically in the neck or chest, to deliver fluids and medicine.
The predicted infection numbers were determined by a Centers for Disease Control and Prevention formula that takes into account hospital size and types of intensive-care units, among other factors.
Five area hospitals did worse than predicted at preventing infections associated with urinary catheters, though several said their numbers had improved since then. And just two local hospitals, Hahnemann University Hospital and Temple University Hospital, were better than predicted at preventing both kinds of infections.
The efforts are driven partly by pressure from insurers to cut costs. Medicare no longer pays for treatment of these infections, along with other conditions deemed to be caused by the hospital. An added penalty was proposed this month: Medicare would cut payments to hospitals whose rates of these infections are too high.
Amid the scrutiny, the numbers have dropped. The CDC estimates that central-line infections fell 41 percent from 2008 to 2011, though an exact comparison is tricky because more hospitals are now reporting.
Hospitals in the eight-county Philadelphia region reported 254 central-line infections in Medicare intensive-care patients from mid-2011 to mid-2012, and 263 urinary-catheter associated infections in the first half of 2012.
Data for prior years were unavailable, because Medicare recently switched from analyzing billing records to clinical data, which is considered more accurate.
Yet, because the infections are reported by the hospitals themselves, some experts suspect that not all cases are submitted. Many states do not audit the data, though Pennsylvania and New Jersey have done so. In California, a review of 100 hospitals found more than one-third of central-line infections were not reported, in some cases due to confusion.
Still, there is real improvement, said Peter J. Pronovost, a Johns Hopkins University researcher who put the issue in the national spotlight by helping Michigan hospitals to slash infection rates.
Pronovost cites what happened in Michigan, where the ICU mortality rate fell 10 percent, compared with 11 states that had yet to adopt broad anti-infection measures.
"Moving mortality in a whole state is unheard of," he said.
So how are local hospitals doing it? Among the tools are:Transparent dressings on central lines, so nurses can check for redness and other signs of infection at the insertion site; Alcohol-infused caps to cover central-line ports that are not in use; Sterile kits that contain all needed equipment, so no one needs to go hunting for supplies; Automated alerts to remove catheters when no longer needed, meaning less time for infections to set in.
Temple and Hahnemann, the two local facilities with good numbers for both infections, also credit committees that review every infection to find out what went wrong.
Some hospitals use catheters with antimicrobial agents, though they cost more, and not everyone thinks they help. Hahnemann uses them.
"You give me a belt, I'll also wear the suspenders," chief medical officer George Amrom said. "It may help."
Just one local hospital, Cancer Treatment Centers of America, did worse than predicted on central-line infections, with six cases instead of the predicted 1.5. Hospital officials note that cancer patients tend to have weak immune systems. Indeed, starting this year the CDC is treating cancer ICUs as a separate category, which may mean such facilities will fare better against national benchmarks.
Above all, Pronovost and local hospitals say success comes from taking responsibility. Take Cooper, where Fluehr-Heinkel says doctors are willing to listen when a nurse points out something is amiss.
With the ventilator patient, she got the doctor to insert a new catheter on the other side of his neck. And it was done right away - whereas in the old days, a doctor would typically wait until finishing his rounds to fix such a problem.
If it was done at all.
