Student finds superbug & # 39; in hands or nostrils of patients staying in the hospital

For decades, hospitals have been working to get doctors, caregivers and others to wash their hands and prevent the spread of microscopes.

But a new study suggests that they also want to expand their efforts for their patients.

Fourteen percent of 399 hospital candidates in the study were "superbug" antibiotic resistant bones on their hands or nostrils very fruit in their hospital stay, the study finds. And almost a third of tests for such bacteria on objects that reach the patients often in their rooms, such as the button knob, positive positive.

Another six percent of those who have no multi-drug resistant organisms, or MDROs, on their hands at the start of their hospitalization, are positive for their hands in their stay test. One-fifth of the objects that were discussed in their rooms also had the same superbugs.

The research team expects that the presence of MDROs on patients or objects in their rooms does not mean that patients are being treated with antibiotic-resistant bacteria. And they notice that healthcare providers are still the primary mode of micro-alignment to patients.

"Hand hygiene story has focused mainly on doctors, nurses and other personnel companies, and all policy and performance issues have focused, and so well," says Lona Mody, MD, M.Sc., University of Michigan geriatrician, epidemiologist and syndrome investigator you lead the research team. "But make our findings an argument for addressing the transfer of MDROs in a way that does not have patients."

Studying the distribution

Mody and her colleague report in the new paper Clinical Infectious Diseases That of six patients in their study who developed an infection with a superbug called MRSA in & # 39; a hospital, all had positive tests for MRSA on their hands and hospital rooms.

In addition to MRSA, short for methicillin-resistant Staphylococcus aureus, the study for superbugs called VRE (vancomycin-resistant enterococcus) and a group called RGNB, sought for resistant Gram-negative bacteria. Because of the addition of antibiotics, these bacteria have developed the ability to keep claims to treat infections with drugs they once killed.

Mody argues that the study suggests that many are viewed as & # 39; view patients also in their rooms in & # 39; a stay where & # 39; t suggests that room transfer is fast. They control prevalence infection in the aging research group at the U-M medical school and the VA Ann Arbor Healthcare System.

In addition, many patients in the hospital come to the emergency room, and can get tests in other areas before they enter their hospital, it is important to keep MDRs ecology in those areas. also to study, she says.

"This research examines the importance of handwashing and environmental environments, especially in a care facility where patient care services are interested," says infectious hospitalist Katherine Reyes, MD, lead author for Henry Ford Health System researchers. # 39; t in & # 39; a study is involved. "This step is important not only for health insurers, but also for patients and their families." T Germs are on our hands, you shouldn't look to believe it, and they travel if they are not washed from person to person make person and objects ill to person and people. "

More about the study

The team made more than 700 visits to the rooms of general medical patients in two hospitals, who worked to enroll their studies and samples of their bodies and often calculated agreements as much as possible in their stay. nobody. They were unable to test rooms before the patients arrived and no patients had surgery, or in intensive care or other types of units.

With genetic fingerprint drawings, they sought to see if the MRSA bacterial strains were at & # 39; The patients were the same as in their rooms. They matched the two in almost all cases – suggesting transfer to and from one patient. The technique is unable to distinguish the direction of transmission, whether it is from patient to objects in the room, or from those objects to patients.

Patient care procedures between patients, particularly if a patient is diagnosed with MDRO infection, have improved over the years, says Mody, and research has shown that they are being used effectively as being used consistently. Removing contaminants from past patients cannot have been an important factor.

But the question of exactly where patients include MDROs that were found on their bodies and handed them over to their surfaces in their rooms is not determined by current study and would be an important next step based on these results.

Why MDRO's business

Also important, says Mody, is the fact that central patients do not only stay in their rooms – current practice encourages them to go up and go in the end as part of their repetition of many illnesses, and they can be transported to other areas of the hospital for testing and procedures.

When traveling, they can retrieve messages from other patients and employees and leave them at the areas they reach.

So even if a relatively healthy person has an MDRO on their skin, and their immune system can do it in its body, a more vulnerable person in the same hospital can catch and get sick. The researchers are investigating the research of MDROs on patients in other types of partnerships, which can be prone to infections.

Patients and staff can also be colonized with MDROs in patient care settings that have become so much of American health care, including urgent care centers, freestanding imaging and surgical centers, and others.

Mody and colleague's present new data on MDROs in their qualified nursing facilities at an infectious conference in Europe in the coming days. They see that privacy curtains – often used to earn patches in the same room, or to see patients looking or looking – are often colonized with superbugs.

"Infection prevention is every business," says Mody, a professor's internal medicine at the U-M medical school. "We are all in & # 39; together, and where you are, in a care or not, this study is a good reminder to often use your hands, using good techniques – especially for and after food to eat, before eating, using a toilet, and for and after one's food, it's sick – to protect yourself and others.
