A new study from the USA highlights how low temperature sterilisation can jeopardise effective cleansing of medical tools and lead to transmission of dangerous bacteria to patients. Steam sterilisation was shown to be the most effective and robust sterilisation technology. However, the researchers, working at the University of North Carolina, also showed that vaporised hydrogen peroxide (VHP)…

In the hustle and bustle of a hospital, properly disinfecting all surfaces in a patient room can be a challenging and time-consuming task. Now, in times of the coronavirus pandemic, it can also be life-threatening. To minimize the risk for their staff, hospitals are utilizing disinfection robots to sanitize surfaces and rooms.

Resistance to antibiotics has become a serious public health problem. Hospital infections, prostheses or surgical implants that become infected and do not respond to treatment are a real challenge to the research community, which has been seeking alternatives for effectively eliminating these bacteria for years. In 2012 the researchers from the Department of Chemical Engineering of the…

Light microscope for viewing microorganisms such as bacteria and fungi are commonly found in scientific laboratories. A research team from Furtwangen University, the University of Tübingen and Carl Zeiss Vision International GmbH, Aalen, examined more closely their role as potential vectors of infectious pathogens. „Very little was known about this until now," explains the head of the…

Despite the use of personal protective equipment (PPE), reports show that many health care workers contracted the coronavirus disease (COVID-19), which raises substantial concerns about the effectiveness of the PPE.

The COVID-19 pandemic is putting extra pressure on radiology services. Radiographers are particularly at risk of catching and spreading the disease. This is why they must follow strict cleaning and disinfection protocols, according to Pablo Valdés Solís, President of the Spanish Society of Radiology (SERAM), who has just published new guidelines on how to protect staff and patients, as the…

Countries where people do not have a habit of washing their hands automatically tend to have a much higher exposure to coronavirus, a new study reveals. University of Birmingham researchers have discovered that at least 50% of people do not have a habit of automatic handwashing after using the toilet in China (77%), Japan (70%), South Korea (61%) and the Netherlands (50%). These countries are…

The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine. The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three…

How long can coronavirus persist on surfaces such as door handles or hospital nightstands? How can the virus be destroyed effectively? A research team from Greifswald and Bochum, Germany, collected the answers scientists can currently offer to these and other pertinent questions and published them in the Journal of Hospital Infection.

WHO Chief Adhanom Ghebreyesus has declared the novel coronavirus (SARS-CoV-2) a global health emergency. He said the decision was reached not because of the situation in China, but because of, “what is happening in other countries.” On Feb. 17, the number of infections totaled around 71,000 globally based on data of the WHO. COVID-19 – the official shorthand name of the novel corona virus…

Modern healthcare without hand hygiene? Inconceivable – particularly in the operating room (OR). But what happens when it is not the surgeon who handles the scalpel, but a robot? Robotic surgery, just like surgery performed by humans, always carries a risk of microbial transmission to the patient, says Professor Johannes K-M Knobloch of University Hospital Hamburg-Eppendorf (UKE). A specialist…

In practice, the drying of the endoscope is often underestimated and therefore a possible pitfall for hygiene and reprocessing steps. As the importance of endoscopic retrograde cholangio-pancreatography (ERCP) procedures and their impact on patients’ lives remains unwavering, the medical community is continuously looking for ways to improve this field of expertise. What better way to learn more…

Nosocomial infections cause more deaths than traffic accidents – a stunning discovery made in a recent German study. Worse: infectious diseases long thought eradicated in Europe, such as measles, tuberculosis (TB) and, more recently, syphilis, are also implicated. The increasing number of patients places an additional financial burden on healthcare. But – and this might be the good news –…

‘Electronic monitoring systems are proven to assist healthcare institutions to make sustained improvements in hand hygiene compliance.’ [Scheithauer S, et al. Do WiFi-based hand hygiene dispenser systems increase hand hygiene Compliance? American Journal of Infection Control (2018)]. ‘Using these systems,’ adds the manufacturer Ophardt Hygiene, ‘a continuous stream of objective data is…

A robot which encourages kids to wash their hands has helped pupils at a remote Indian primary school take a fresh approach to hygiene. The hand-shaped robot, dubbed ‘Pepe’, is the product of a collaboration between researchers from the University of Glasgow in Scotland and Amrita Vishwa Vidyapeetham University in India. Pepe was mounted to the wall above a handwashing station at the Wayanad…

Nosocomial infections present enormous challenges for medical facilities, involving huge hygiene efforts from staff, on patients as well as medical and non-medical products. At MedtecLIVE 2019, in Nuremberg, Susanne Harpel (Dipl. Ing), Deputy Head of the Institute for Hygiene and Environmental Medicine at Giessen/Marburg University Hospital, presented desirable contamination efforts during the…

Bacteria are becoming increasingly resistant to common antibiotics. Often, resistance is mediated by resistance genes, which can simply jump from one bacterial population to the next. It’s a common assumption that the resistance genes spread primarily when antibiotics are used, a rationale backed up by Darwin's theory: only in cases where antibiotics are actually being used does a resistant…

In view of the increase of multidrug-resistant organisms (MDRO), the WHO has declared antibiotic resistance one of the biggest threats to global health. MDROs have become a major problem particularly in hospitals. Professor Dr Georg Häcker from the Institute for Microbiology and Hygiene at the University Hospital Freiburg, explains some strategies to prevent hospital-acquired infections (HAIs).

In endoscope reprocessing, time and storage space are always limited. During the ESGE Days in Prague the IKEM hospital facilitated the live procedures and had to deal with an exceptionally high demand for endoscope reprocessing. Hana Kubecova, head nurse of their endoscopy department, explains how a new solution, the PlasmaTYPHOON, helped her team to deal with this high work load whilst still…

Recent publications have stated that several outbreaks have been caused by insufficient drying of duodenoscopes. Due to their complex design, duodenoscopes have been long recognized to require thorough processes and precise execution to properly disinfect. Read more to understand how Pentax Medical is tackling hygiene as both a challenge and priority within endoscopy.

Sixty-two percent of Germans fear antibiotic resistance, according to a survey recently conducted by the German Federal Institute for Risk Assessment. ‘Patients colonised by multi-resistant pathogens are particularly scared. But many of these fears are rooted in misunderstandings,’ explained Professor Mathias Pletz at the Congress for Infectious Diseases and Tropical Medicine (KIT).

Hospital hygiene and how Germany compares in a European survey is somewhat divisive. Some believe Germany does well, whilst others emphasise the need to improve and for a stronger alignment with countries such as the Netherlands. As hygiene specialist Professor Petra Gastmeier, at the Institute of Hygiene and Environmental Medicine in Charité University Medical Centre Berlin, pointed out:…

Insufficient knowledge of infection control, resulting in insufficient compliance, increases the risk of hospital acquired infections (HAIs) and multiresistant pathogens that put patients at risk. At the 2019 Annual General Meeting of the German Society for Hygiene and Microbiology e.V. (DGHM) in Göttingen, Professor Frauke Mattner, Senior Consultant at the Institute of Hygiene, Kliniken der…

Antiseptic soap, mouthwash, and nose ointment after hospital discharge reduced infections and infection-associated hospitalizations due to MRSA in high-risk patients.
