Most healthcare-associated urinary tract infections (HAUTIs) including catheter associated urinary tract infections (CAUTIs) are potentially preventable through implementation of effective strategies. To provide the foundation for a national point prevalence study of HAUTIs including CAUTIs, a three phase project was developed. This study reports the findings of Phase II which aimed to (1) pilot an online process including online database for conducting point prevalence survey of HAUTIs and CAUTIs and (2) determine the point prevalence of HAUTIs and CAUTIs in acute and aged care facilities

Background: In the past decade the policy and practice context for infection control in Australia and New Zealand has changed, with infection control professionals (ICPs) now involved in the implementation of a large number of national strategies. Little is known about the current ICP workforce and what they do in their day-to-day positions. The aim of this study was to describe the ICP workforce in Australia and New Zealand with a focus on roles, responsibilities, and scope of practice.

Methods: A cross-sectional design using snowball recruitment was employed. ICPs completed an anonymous web-based survey with questions on demographics; qualifications held; level of experience; workplace characteristics; and roles and responsibilities. Chi-squared tests were used to determine if any factors were associated with how often activities were undertaken.

Results: A total of 300 ICPs from all Australian states and territories and New Zealand participated. Most ICPs were female (94%); 53% were aged over 50, and 93% were employed in registered nursing roles. Scope of practice was diverse: all ICPs indicated they undertook a large number and variety of activities as part of their roles. Some activities were undertaken on a less frequent basis by sole practitioners and ICPs in small teams.

Conclusion: This survey provides useful information on the current education, experience levels and scope of practice of ICPs in Australia and New Zealand. Work is now required to establish the best mechanisms to support and potentially streamline scope of practice, so that infection-control practice is optimised.

This quarterly surveillance report provides an overview of the Tasmanian acute public hospitals healthcare associated infection surveillance. The TIPCU website (www.dhhs.tas.gov.au/tipcu) contains details of the surveillance program and the methodologies used in data collection, validation and analysis. These details are not contained in this report but are freely available online should further information be required.

The purpose of this review is to describe some of the main methodologies currently used in assessing environmental cleanliness as well as document current local, national and international practices.

The objective of this study was to examine the effect of self-reported breakfast size, daily eating, and other health habits on body mass index (BMI). We hypothesized that a consumption of a substantial breakfast compared with skipping or small breakfasts would be associated with lower BMI. Three independent, cross-sectional, screening surveys were conducted by Sydney Adventist Hospital in 1976, 1986, and 2005 in the surrounding community. The archived survey forms of 384 men and 338 women in 1976, 244 men and 229 women in 1986, and 270 men and 62 women in 2005 were randomly selected. Body mass index was determined from height and weight measured by hospital staff. The reported amount consumed at breakfast was one of several eating habits that predicted BMI for men but not women. It explained 5% to 6% of the variance in male BMI in all 3 years examined. As the reported breakfast amount increased, men's BMI decreased. Lifestyle confounders including vegetarianism and physical activity did not affect this relationship. However, the consumption of breakfast was significantly positively associated with consumption of cereals, bread, fruit, and spreads, while coffee consumption was significantly associated with smaller breakfasts or breakfast skipping. The consumption of relatively large breakfasts may influence BMI in men, and its promotion may help reduce the prevalence of obesity in Australia and elsewhere.

On 8 April 2011, the Communicable Disease Prevention and Control Unit (CDPCU) of the Victorian Department of Health was advised that three adolescents from the same family had been admitted to a metropolitan hospital for treatment of dehydration secondary to diarrhoea. Other symptoms included fever and vomiting. Initial enquires suggested that the adolescents may have become infected after eating fried eggs for breakfast at their aunt’s home over three consecutive days, or dinner at a Chinese restaurant. Six days later two more notifications of salmonellosis were received by CDPCU; both cases had eaten at the same Chinese restaurant. Also on this day, the Department was notified that Salmonella spp. was isolated from two of the original adolescent’s faecal specimens.

An investigation was initiated to characterise the outbreak, identify the source and possible cause of the infection and to prevent ongoing transmission of the infection.

Cryptosporidiosis is a protozoan parasitic infection that most commonly presents as gastroenteritis and less commonly infects the respiratory and biliary tracts. Enteric symptoms usually include diarrhoea, bloating, cramping, abdominal pain, vomiting and fever. The disease is usually mild and self-limiting but in immunocompromised individuals is prolonged and can lead to death. The infective dose in humans is low and the incubation period ranges from one to 12 days, with an average of seven days. The infectious period lasts from the onset of symptoms, as the oocysts are excreted in the stool, until several weeks after symptoms resolve.

The oocysts are widespread and may remain infective outside the body for two to six months, particularly if the environment is moist. They are highly resistant to standard levels of chemical disinfection of water such as chlorine. Outbreaks have been reported in day care centres, and been associated with drinking water, recreational water (waterslides, swimming pools and lakes) and consumption of contaminated beverages. In Australia, increases in notifications tend to occur in the warmer months and over irregular cycles, with more than 3000 cases notified in Australia in 2002, 2005 and 2006.

Cryptosporidiosis became notifiable in both Australia and Victoria in 2001, with more than 15,000 cases notified between 2002 and 2009. The aim of this study was to describe the epidemiology of notified cases of cryptosporidiosis in Victoria for the period 2001 to 2009 in terms of age, sex, location and season.

Surveillance of healthcare-associated infections is central to healthcare epidemiology and infection control programmes and a critical factor in the prevention of these infections. By definition, the term ‘infection prevention’ implies that healthcare-associated infections may be preventable. The purpose of surveillance is to provide quality data that can be used in an effective monitoring and alert system and to reduce the incidence of preventable healthcare-associated infections. This article examines the purpose of surveillance, explains key epidemiological terms, provides an overview of approaches to surveillance and discusses the importance of validation.
