COVID-19 outbreak management in a mental healthcare setting.

Since the beginning of the novel coronavirus disease pandemic (COVID-19), inadvertent exposure of hospitalised patients and healthcare workers has been a major concern. Patients in inpatient settings with mental illnesses have also been impacted by the restrictions the pandemic has caused, with many having experienced the confines and loss of liberties that COVID-19 has brought. This article identifies the infection prevention and control measures required in a mental health setting during an outbreak of COVID-19. The focus is on the challenges of working in a mental health setting and identifies the difficulties in containing the infection within this ill-designed built environment and includes the additional pressures of managing this complex and diverse group of patients. Current guidance on outbreak measures is given with particular attention applied to the patients, the practices and the environment.

Strategies to reduce Gram-negative infections: a community perspective.

Infections caused by Gram-negative bacteria continue to be on the rise, despite efforts by the Government and health service to curb their numbers. Most of these infections arise in the community. The case for targeting community-onset healthcare-associated infections is stark and requires a shift in focus from traditionally providing increased efforts in the hospital setting to a diversion of attention to the community. This article describes the challenges faced with increasing Gram-negative bloodstream infections and explores measures being taken to reduce transmission. As recent guidance has highlighted a proliferation within the community setting this article particularly focuses on a three-point plan for primary care. The strategies laid out are to reduce urinary tract infections, improve hydration and control antibiotic usage. Adopting these strategies will assist in reducing infection and targeting efforts where they are needed most.

Do training and needle-safety devices prevent needlestick injuries? A systematised review of the literature.

This systematised review was undertaken to appraise research on the effects of training and the use of needle-safety devices (NSDs) on the prevention of needlestick injuries (NSIs) among health workers, focusing on a European perspective. A literature search from 2007 to 2017 was performed, which identified six studies that investigated the introduction of training and NSDs and their affect on NSIs. The six chosen studies identified that training, as well as the adoption of NSDs, has an impact on preventing NSIs. However, further information is required on the content and mode of delivery of training and on which types of NSDs are most effective at preventing injuries. This will help healthcare workers to understand and implement the most effective strategies to prevent injuries. This article provides a critique of the research approaches used in the six studies.

Infection prevention and control practitioners: improving engagement.

Every healthcare worker plays a vital part in minimising the risk of cross infection. Infection prevention and control (IPC) practitioners have the skills and competencies to assist organisations in improving engagement among staff and play a vital part in achieving this. IPC practitioners have skills in clinical practice, education, research and leadership, and these skills ensure high-quality care for patients and support strategies for engaging staff. This article highlights how IPC practitioners' skills and competencies are required for preventing infection and improving staff engagement. Engaged staff generate positive outcomes for both patients and staff, which is a welcome result for all healthcare organisations.

The role of healthcare strategies in controlling antibiotic resistance.

In an interview in March 2013, the Chief Medical Officer described antibiotic resistance as a 'ticking time bomb' and ranked it along with terrorism on a list of threats to the nation. Her report Infections and the Rise of Antimicrobial Resistance (Department of Health, 2011) highlighted that, while a new infectious disease has been discovered nearly every year over the past three decades, there have been very few new antibiotics developed, leaving our armoury nearly empty. Antibiotic resistance is a universal problem that needs to be tackled by a wide variety of strategies and players. Our approach to tackling resistance to antibiotic agents must therefore also be dynamic. As well as reducing environmental use, we also need to lower antibiotic use in the healthcare setting. Healthcare workers have a huge role to play in combating antibiotic resistance. This article focuses on several issues related to antibiotic resistance, including antibiotic modes of action and the properties that confer resistance on bacteria. It includes information on antibiotic usage and describes current healthcare strategies we can adopt to help reduce the development of resistance.

Improving influenza vaccine uptake in frontline staff.

Influenza is a highly contagious upper respiratory tract disease causing significant morbidity and mortality among high-risk groups. Immunization of frontline healthcare workers (HCWs) in the NHS is thought to be beneficial in reducing subclinical infection, staff sickness absences and protects patients. Each year Public Health England launches the Seasonal Flu Campaign to help reduce influenza transmission by reinforcing the message that it is vital that frontline HCWs get vaccinated. Public Health produces figures on frontline workers who have been vaccinated annually. The 2011/2012 campaign showed uptake figures of the influenza vaccine was averaging 44.6% nationally. The efforts of an NHS trust to increase staff uptake of the annual seasonal flu vaccination programme has been highly commended as it achieved an impressive 68.7% uptake against a target of 70%. This article shows how the trust worked hard to improve uptake on flu vaccinations for HCWs during the 2012/2013 flu season. Recognised as a Top Improver by NHS Employers (2013) for vaccination uptake, the Trust identifies how measures can be adopted to improve vaccination rates and what barriers can prevent total compliance. High rates of HCW vaccination can benefit staff, patients and the communities within which they work and live.

Subcutaneous injections: preventing needlestick injuries in the community.

Community nurses provide care to patients in a variety of settings, for example health centres, community hospitals, patients' homes, residential and nursing homes. Administering subcutaneous injections to patients in the community is an everyday activity for many nurses in clinical practice. Many problems related to being 'sharps safe' are common to both community nurses and hospital staff. The majority of subcutaneous injections administered in the community are for patients with diabetes. Reducing needlestick injuries after the administration of subcutaneous injections in the community remains paramount to all NHS staff. This article provides information on what national standards to employ when administrating subcutaneous injections and what safety practices should be undertaken for good sharps management. Staff administering subcutaneous injections in the community need to ensure that they are updated on the latest developments in safety needle devices in order to prevent needlestick injuries and provide safe, effective and individualised care for their patients.

Reducing needlestick injuries: a review of a community service.

Community nurses provide care to patients in a variety of settings; for example, health centres, community hospitals, patients' homes, and residential and nursing homes. Administering intramuscular (IM)injections to patients in the community is an everyday activity for many nurses in clinical practice. A great deal of problems related to being 'sharps safe' are common to both community nurses and hospital staff. There had been a reported six needlestick injuries (NSIs) from community clinics administering depot IM injections, which required a review. An audit of practice was undertaken in clinics administering depot injections. The audit was undertaken to monitor compliance in sharps management and investigated how community nurses were administering IM injections. The review highlighted a lack of resources, gaps in knowledge and training deficits. The infection prevention and control nurses worked hard to improve practices and procedures. After a year, there had been a significant reduction in NSIs.

Mattress cleanliness: the role of monitoring and maintenance.

A clean and tidy environment provides the right setting for good patient care. It is fundamental in preventing and/or controlling the spread of healthcare-associated infections (HCAI). Cleanliness is an essential component for the comfort and dignity of patients, particularly those for whom a hospital is home for any length of time. Patients spend a lot of their time in bed so it is important for them to be provided with well maintained and clean mattresses. Beds, and especially the mattresses, should be cleaned and inspected regularly so patients know they are being cared for in a clean and safe environment. To prolong the life of the mattress and reduce infection risks, inspections for damage and contamination must take place on a regular basis. Assessment criteria for the audit of a mattress can include a visual inspection, a cover permeability test and a foam support surface test. These assessments will ensure the mattress is compliant with current standards and identify whether or not they require condemning. Mattress care can be improved by adopting unified good practices that can be standardized and audited regularly.

Managing outbreaks of norovirus in an NHS hospital.

Noroviruses are highly infectious and easily transmitted by contact with contaminated surfaces and objects, as airborne particles and by contact between individuals. While illness caused by norovirus is usually self-limiting, it can be serious in very young and elderly people, or in those who are debilitated or have a serious illness; they may require hospital treatment. Norovirus outbreaks in hospitals create significant disruption to patient care. They also have huge cost implications for NHS trusts through staff absence and ward closures, which are extremely disruptive and increase pressures on bed demand. The three most important actions during an outbreak of norovirus are effective hand hygiene, isolation of affected patients and enhanced cleaning of the environment. This article outlines how to identify norovirus infection and outbreaks, and describes how an acute trust managed outbreaks of norovirus and the procedures it adopted.

Cannulae and infection control in theatre.

Healthcare-associated infections (HAIs) are those that are not present or incubating when an individual enters hospital, but are acquired while in hospital. At any one time, 8% of patients have an infection acquired in hospital (Department of Health (DH), 2008). On average, an infection adds 3-10 days to the length of a patient's stay in hospital. It can cost pound4000- pound10 000 more to treat a patient with an infection than one without an infection (DH, 2008). It is not surprising, then, that attention has been focused on tackling HAIs and, in particular, in-dwelling devices such as cannulae that have a potential for causing infections.

Sternal wound infections: improvements made to reduce rates.

Wound infections from surgical sites account for 15% of all healthcare-associated infections (National Institute for Health and Clinical Excellence (NICE), 2008). There is evidence that the care provided before and after the operation is paramount to minimize the risk of surgical site infection. Sternal wound infections lengthen hospital stays (or prompt readmission) and carry a high mortality rate. In August 2009 a Manchester Hospital discovered a cluster of three patients with sternal wound infections. A review of clinical data for patients having cardiac surgery from 1 December 2008 and 9 October 2009 revealed an increased incidence of patients with sternal wound infections. The data did not reveal a significant problem, but one that should be kept under observation. During the investigation no single pathogen had been identified as responsible and no obvious source of environmental infection was identified. Implementing additional infection prevention and control practices helped the hospital team to improve the care given to patients. A host of factors, ranging from providing more information on wound care to patients, improving audit scores, and adhering to NICE guidelines, contributed to the reduction in this type of surgical site infection.

Improving peripheral IV cannula care: implementing high-impact interventions.

Infection prevention and control measures have been recognized as effective in minimizing the risk of infection from peripheral intravenous (IV) cannulas. However, this relies on health professionals' compliance with guidelines for the care of patients with IV catheters and at times it may be that practice is inconsistent with guidelines. This article discusses the care required for peripheral cannulas and shows how implementing the high-impact interventions can improve peripheral IV catheter care on insertion and its management afterwards.

Clostridium difficile infection: A critical analysis of the guidance.

A recent report by the Department of Health, Clostridium Difficile Infection: How to deal with the problem - a board to ward approach, is a revised set of guidelines based on best practice and key recommendations for the NHS to ensure the control of Clostridium difficile infection (CDI). It takes into account a national framework for clinical governance which did not previously exist, a framework that gives significant weight to infection control as a matter of patient safety, and highlights that all clinicians have a personal responsibility for infection prevention and control. It puts the onus on Trust management and PCTs to ensure that measures are in place to prevent and manage CDI according to best evidence. However, the report fails to explain how these measures will have an impact on finance and resources on an already burdened system. The author explains how much of the report is comparable with the one published in 1994, and highlights many of its limitations within the busy hospital setting. Reducing CDI is achievable, as many hospitals are showing large reductions in their CDI rates. Healthcare workers must be applauded for their success in reducing CDI, but there is more to be done.

C. difficile infection - a tool for improving practice and reducing rates.

Clostridium difficile infection (CDI) is a recognized health-care-acquired infection (HAI) and as such it is vital that hospitals do more to reduce the rates of infection. Patients, especially older people, become particularly susceptible to CDI after treatment with antibiotics. Mention of CDI on death certificates is increasing and surveillance, especially when accompanied by feedback to clinicians, has long been established as an effective tool to lower HAIs. In February 2008, a Manchester hospital began to pilot the Root Cause Analysis (RCA) tool for all patients confirmed with a CDI. After receiving feedback from clinicians on its appropriateness and suitability, the RCA tool was amended accordingly and then implemented into practice. The RCA tool has significantly improved practice and collaborative working - it has enhanced teamwork and ultimately reduced infection. This article examines how the tool was embedded in the Trust, how the change process has been managed and ultimately, how patient care has benefited as a result.

Sharps management in hospital: an audit of equipment, practice and awareness.

The safe handling and disposal of needles and other sharp instruments forms part of an overall strategy to protect staff, patients and visitors from exposure to blood-borne pathogens. As with many infection prevention and control policies, the assessment and management of the risks associated with the use of sharps is paramount, and safe systems of work and engineering controls must be in place to minimize any identified risks. The use of sharps in hospitals should be avoided where possible; when their use is essential, particular care is required in handling and disposal - if possible, use safer sharps devices. An audit of sharps management was undertaken to observe equipment, practice and awareness. The audit reported very positive results. However, some areas needed further review to improve practice. The infection control team implemented an action plan as a result of the audit and set about initiating measures for training and awareness. It is necessary to audit sharps management routinely to have an accurate assessment of current practice and prevent occupational exposure to blood-borne pathogens.

Tunable Nanoscale Cages from Self-Assembling DNA and Protein Building Blocks.

Three-dimensional (3D) cages are one of the most important targets for nanotechnology. Both proteins and DNA have been used as building blocks to create tunable nanoscale cages for a wide range of applications, but each molecular type has its own limitations. Here, we report a cage constructed from both protein and DNA building blocks through the use of covalent protein-DNA conjugates. We modified a homotrimeric protein (KDPG aldolase) with three identical single-stranded DNA handles by functionalizing a reactive cysteine residue introduced via site-directed mutagenesis. This protein-DNA building block was coassembled with a triangular DNA structure bearing three complementary arms to the handles, resulting in tetrahedral cages comprising six DNA sides capped by the protein trimer. The dimensions of the cage could be tuned through the number of turns per DNA arm (3 turns ∼ 10 nm, 4 turns ∼ 14 nm), and the hybrid structures were purified and characterized to confirm the three-dimensional structure. Cages were also modified with DNA using click chemistry and using aldolase trimers bearing the noncanonical amino acid 4-azidophenylalanine, demonstrating the generality of the method. Our approach will allow for the construction of nanomaterials that possess the advantages of both protein and DNA nanotechnology and find applications in fields such as targeted delivery, structural biology, biomedicine, and catalytic materials.

Pandemic influenza: implications for infection control in hospital.

The World Health Organization states that immediate action is needed to prevent a repeat of the 1918 flu pandemic, which killed an estimated 40 million people globally. The infection control team in hospitals are given responsibilities to implement plans to deal with an event if one should occur. Many healthcare facilities belonging to primary care Trusts and particularly hospitals have been ordered to release a pandemic influenza policy. It is a policy that states the clinical features attributable to avian influenza, its possible transmission and information on general infection control precautions. It is necessary for hospitals to be prepared in its management for a potential influenza outbreak and have the necessary resources to execute infection control practices. This article outlines the infection control precautions that need to be implemented in hospitals in the event of pandemic influenza, and the various practices to adopt when coming into contact with patients with signs and symptoms of influenza. Only by adopting the recommended infection control practices can we be assured that transmission will be minimized.
