Agencies look to prevent transmission
Methicillin-resistant Staphylococcus aureus (MRSA) is common in most hospitals, but a recent study shows that almost 13% of patient discharged from the hospital to home health care are infected with MRSA.1
"There has been an increase in the number of patients coming to home health with MRSA," admits Marcia R. Patrick, RN, MSN, CIC, director of infection control for Multicare Health Systems in Tacoma, WA. "In 2000, we typically saw about 7% of patients admitted from hospitals to home health colonized with MRSA; now we see 12%," she says.
The most common patients to have MRSA are patients who are considered "frequent fliers," Patrick says. "Patients with a lot of hospital admissions are more likely to be exposed to MRSA and are more likely to have medical conditions that put them at risk for infection," she explains.
In general, home health agencies are not screening new admissions for MRSA or other multidrug-resistant organisms (MDROs), says Patrick. "At our hospital system, patients discharged from the intensive care unit are screened as are other high-risk patients, so we do know if they have MRSA when admitted," she says. "Other patients who don't receive screening in the hospital are not screened unless we have a problem such as a wound that does not heal."
The difficulty in selecting which patients might require screening at admission is that about half of patients who are colonized with MRSA do not have any symptoms or risk factors, she says.
Although some hospitals do have MRSA screening programs, they don't address all patients, just patients in high-risk areas such as intensive care, says Irena L. Kenneley, PhD, APRN-BC, CIC, professor at Case Western University in Cleveland.
The Association for Professionals in Infection Control and Epidemiology (APIC) Scientific Research Council funded a study to find out the national prevalence of MRSA at U.S. health care facilities in the form of a survey sent to infection control professionals across the country.2 "The APIC MRSA inpatient survey found that the MRSA colonization and infection prevalence in U.S. health care facilities is 46.3 per 1,000 inpatients, which is eight to 12 times higher than previous estimates," Kenneley says. "What has important implications for home health care is that it was also found that 67% of MRSA identified were on medical services, suggesting that MRSA is not focused just in ICU or surgical patients. As for active surveillance cultures, only 28% of the respondents performed them."
Patrick says, "We really can't do a thorough risk assessment for MRSA unless we screen, but implementing a screening program in home health presents some challenges." Not only is reimbursement for the cost of test an issue, but also additional training would be required to ensure that the screening test is conducted properly, she says. "The most commonly used method, swabbing the nose, still requires proper technique to obtain accurate results," Patrick says.
Although her agency does not conduct routine screenings for MRSA or other MDROs upon admission, Judie Truelsen, RN, BSN, interim co-director of Northwest Community Home Care in Arlington Heights, IL, will contact physicians for orders to culture wounds that are not healing to check for MRSA and other organisms, she says.
In the absence of thorough MRSA screening programs for hospitals and home health agencies, the best way to protect patients, family members, and staff members from transmission of MRSA is to assume that everyone is potentially infected, suggests Truelsen. "We teach our staff members to use standard precautions in all patients' homes to prevent the spread of MRSA and any other infection," she says.
Rather than single out MRSA in infection control practices, it works best to expect standard precautions to be followed all of the time, Truelsen says. "This is the best way to develop good habits and practices and makes it much easier to remember what should be done to prevent the spread of any infection," she adds.
Although MRSA patients can be decolonized after initial exposure, they are at risk for contracting MRSA again, Patrick says. "Once MRSA, always MRSA," is the rule followed by her staff. "A patient with MRSA contaminates his or her home, so some areas can't be disinfected," she adds. "A kitchen and bathroom are easy to disinfect, but sofas, chairs, and rugs can't be disinfected so remove all traces of MRSA," Patrick explains. This is another reason that Patrick emphasizes the use of standard precautions in all homes.
Kenneley says, "We will not fix the problem of increasing rates of infection and colonization caused by MDROs overnight." The solutions are not simple given the complex health care delivery system, she says. "Solutions will require increased support for ownership of infection control and prevention not only in home health, but also throughout the entire health care delivery system."
