An audit of the use of manual handling equipment and their microbiological flora--implications for infection control

The fall and rise of cleanliness in British healthcare and the nursing contribution

This paper discusses the term ‘cleanliness’ and applies it to healthcare. Ways of achieving cleanliness in premises where healthcare is delivered are explored. It is concluded that although once a world-leader in infection control practice and research, the United Kingdom is now lagging behind other countries. Traditionally hands have been regarded as the main vectors of healthcare-associated infection. However, hands can never be rendered entirely free of micro-organisms, so it is inevitable that healthcare-associated infection will always be a challenge. Decontamination of the healthcare environment, its fixtures, fittings and clinical equipment are also of pivotal importance in maintaining cleanliness, controlling infection and regaining consumer confidence in healthcare. Nurses play a major role in ensuring that appropriate decontamination processes and procedures are in place to meet required standards. To do so they must receive the appropriate education and training.

Prevention of endemic healthcare-associated Clostridium difficile infection: reviewing the evidence

OBJECTIVES

Clostridium difficile is the most common infectious cause of healthcare-associated diarrhea. Because of the increasing incidence and severity of endemic C. difficile infection (CDI), interventions to prevent healthcare-associated CDI are essential. We undertook a systematic review of interventions to reduce healthcare-associated CDI.

METHODS

We searched multiple computerized databases, and manually searched for relevant articles to determine which interventions are useful in preventing CDI. Studies were required to be controlled in design and to report the incidence of endemic CDI as an outcome. Data on the patient population, intervention, study design, and outcomes were abstracted and reviewed using established criteria.

RESULTS

Few randomized controlled trials exist in the area of CDI prevention. The interventions with the greatest evidence for the prevention of CDI include antimicrobial stewardship, glove use, and disposable thermometers. Environmental decontamination also may decrease CDI rates, although the level of evidence is not as strong as for the other proven interventions. Treatment of asymptomatic carriage of C. difficile is not recommended. There is insufficient evidence to make a recommendation for or against the use of probiotics. In cases of known or suspected CDI, hand hygiene with soap and water is preferred over use of waterless alcohol hand rub. Many nonrandomized trials included in our analysis used multiple interventions concurrently, making the independent role of each preventive strategy difficult to determine. We chose to include only studies that focused on endemic CDI because studies of outbreaks have used multiple strategies, making it difficult to measure the relative efficacy of each strategy. Environmental disinfection and probiotics need to be studied further to evaluate their roles in the prevention of CDI. Although there have been no studies assessing the utility of isolation and cohorting for the prevention of endemic CDI specifically, it is a widely used intervention for containment of this and other similar multidrug-resistant pathogens.

CONCLUSIONS

Antimicrobial stewardship, glove use, hand hygiene, and disposable thermometers should be routinely used for the prevention of CDI. Environmental disinfection and probiotics should be studied further for their role in reducing CDI.

Clostridium difficile-associated disease: update and focus on non-antibiotic strategies

Clostridium difficile-associated disease (CDAD) is a problem of especially the frail elderly. Changes in virulence of prevalent strains in the early years of the new century saw mortality and morbidity increase from historical levels. This article explores non-antibiotic strategies including the use of probiotics. A number of avenues of ongoing research appear to have potential future clinical application. Evidence exists linking acid-inhibiting drugs to an increased risk of CDAD, and the adjunctive use of Saccharomyces boulardii and infection control measures in the treatment of CDAD.

Comparison of cumulative low back loads of caregivers when transferring patients using overhead and floor mechanical lifting devices

BACKGROUND

Mechanical lifting devices are recommended as an important intervention for reducing lifting injuries among nursing personnel; previous research suggests that spinal loads are not minimized for all device types. The purpose of this study was to describe the spinal loading pattern while performing a bed to chair transfer comparing Overhead and Floor powered lifting devices.

METHODS

A Latin Square design was employed to evaluate five lifting devices while performing a heavy patient transfer. The primary outcomes were spinal compression, and anterior shear (across median and cumulative loading conditions), and ratings of perceived exertion. An inverse dynamic approach was used to calculate the net joint forces and moments about the L5/S1 spinal level. The transfer was partitioned into seven distinct phases for biomechanical analysis.

FINDINGS

The proportion of time spent and the mean loads sustained in each phase of the transfer were described. Significant differences in loads were observed between the differing lifting devices, particularly during the transport phases for the Overhead devices. Nurse subjects consistently ranked Overhead lifting devices as most preferred.

INTERPRETATION

A large proportion of the time to complete the transfer and cumulative loads occurred during phases that involved only the sling and not the mechanical component of the device. Overhead lifting devices were shown to have lower spinal loads during the transport phases. The results of this study have implications for the use and selection of mechanical lifting devices as part of a strategy to reduce back injuries.

Advantages of low-cost mobility aids in health-care settings

Rope bed ladders, hand blocks and transfer boards have been available for years in a number of health-care settings. They are recommended for clients with some mobility, who would otherwise need manual assistance, yet research indicates that they are an underused resource.

This article sets out to promote awareness of these and similar ‘low-tech’ aids by identifying the advantages of promoting independence by equipping and educating clients to move themselves.

The use of hand blocks, bed ladders, lifting poles (‘monkey poles’) and transfer boards are examined. The type of patients for whom they may be helpful, the assessment of the clients and contraindications are considered and recommendations are made for the provision of these aids.

Bacterial contamination of uniforms

Microbiological sampling of nurses' uniforms was undertaken using a Casella slit sampler. Staphylococcus aureus, Clostridium difficile and vancomycin-resistant enterococci were detected on uniforms both before and after a span of duty. Recommendations for provision and changing of nurses' uniforms are made.
