Emergence of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infection in Queensland, Australia

Objectives: To investigate the incidence and epidemiology of non-multiresistant methicillin-resistant Staphylococcus aureus (nmMRSA) infection in south-east Queensland, Australia. Study design: A retrospective survey was done of hospital records of all patients who had non-multiresistant MRSA isolated at Ipswich Hospital (a 250-bed general hospital, 40 km south-west of Brisbane, Queensland, Australia) between March 2000 and June 2001. Laboratory typing of these isolates was done with antibiogram, pulsed-field gel electrophoresis, bacteriophage typing and coagulase gene typing. Results: There were 44 infections caused by nmMRSA. Seventeen infections (39%) occurred in patients from the south-west Pacific Islands (predominantly Samoa, Tonga and New Zealand). Laboratory typing showed that the isolates in Pacific Islanders were Pacific Island strains, and 16/17 of these infections were community acquired. Twenty-three infections (52%) occurred in Caucasians. Eleven of the isolates from Caucasians (48%) were a new predominantly community-acquired strain that we have termed the ‘R’ pulsotype, nine (39%) were Pacific Island strains, and three (13%) were health care institution-associated strains. Four infections occurred in patients who were not Caucasians or Pacific Islanders. Overall, 34 of all 44 infections (77%) were community' acquired. Conclusions: Non-multiresistant MRSA infection, relatively frequently observed in Pacific Islanders in south-east Queensland, is now a risk for Caucasians as well, and is usually community acquired. Clinicians should consider taking microbiological specimens for culture and antimicrobial susceptibility testing in patients with suspected staphylococcal infections who are not responding to empirical therapy with β-lactam antibiotics.

Acceptability and feasibility of a community-based screening programme for melanoma in Australia

The evaluation of a community-based screening programme for melanoma (SkinWatch) in 18 regional communities (total adult population >30 years 63 035) in Queensland, Australia is described. The aim of the SkinWatch programme was to promote whole-body skin screening for melanoma by primary care physicians. The programme included community education, education and support for local medical practitioners and open-access skin screening clinics. Programme delivery was achieved through assistance of local volunteers. All programme activities and resources were recorded for process evaluation. A baseline telephone survey (n = 3110) and a telephone survey four months after programme launch (n = 680) assessed community awareness of the SkinWatch programme and, 37 face-to-face interviews with community members, doctors and community leaders were conducted to assess satisfaction with the programme. A sample of 1043 of 16 383 residents who attended the skin screening clinics provided as part of the programme were interviewed to assess reasons for attending, and positive and negative aspects of SkinWatch programme. Community awareness of the SkinWatch programme increased by over 30% (p < 0.001) within four months of the start of the programme. Interview participants described the SkinWatch programme as a useful service for the communities and 90% stated they would revisit the clinics. A total of 43% of all attendees were over 50 years old, and nearly 50% were men. These findings demonstrate the acceptability and feasibility of a community-based screening programme for melanoma in rural areas. Volunteers were instrumental in increasing community ownership of and involvement in the SkinWatch programme.

Genetic diversity among community methicillin-resistant Staphylococcus aureus strains causing outpatient infections in Australia

Increasing reports of the appearance of novel nonmultiresistant methicillin-resistant Staphylococcus aureus MRSA (MRSA) strains in the community and of the spread of hospital MRSA strains into the community are cause for public health concern. We conducted two national surveys of unique isolates of S. aureus from clinical specimens collected from nonhospitalized patients commencing in 2000 and 2002, respectively. A total of 11.7% of 2,498 isolates from 2000 and 15.4% of 2,486 isolates from 2002 were MRSA. Approximately 54% of the MRSA isolates were nonmultiresistant (resistant to less than three of nine antibiotics) in both surveys. The majority of multiresistant MRSA isolates in both surveys belonged to two strains (strains AUS-2 and AUS-3), as determined by pulsed-field gel electrophoresis (PFGE) and resistogram typing. The 3 AUS-2 isolates and 10 of the 11 AUS-3 isolates selected for multilocus sequence typing (MLST) and staphylococcal chromosomal cassette mec (SCCmec) analysis were ST239-MRSA-III (where ST is the sequence type) and thus belonged to the same clone as the eastern Australian MRSA strain of the 1980s, which spread internationally. Four predominant clones of novel nonmultiresistant MRSA were identified by PFGE, MLST, and SCCmec analysis: ST22-MRSA-IV (strain EMRSA-15), ST1-MRSA-IV (strain WA-1), ST30-MRSA-IV (strain SWP), and ST93-MRSA-IV (strain Queensland). The last three clones are associated with community acquisition. A total of 14 STs were identified in the surveys, including six unique clones of novel nonmultiresistant MRSA, namely, STs 73, 93, 129, 75, and 80sIv and a new ST. SCCmec types IV and V were present in diverse genetic backgrounds. These findings provide support for the acquisition of SCCmec by multiple lineages of S. aureus. They also confirm that both hospital and community strains of MRSA are now common in nonhospitalized patients throughout Australia.

Neoliberalism, individualisation and community: Regional restructuring in Australia

Since the early 1980s, Australian governments have embraced neoliberal policies as a means of improving the nation’s global economic competitiveness. The impacts of such policies in regional areas have been quite profound, leading to socio-economic polarisation, population loss, and the growth of anti-globalisation sentiments. In this paper, we examine the process of regional restructuring that arises from this trajectory in Australia, and examine current policy responses to change under the neoliberal regime. We argue that while many such responses are individualistic, and based upon policies of personal responsibility, self-advancement and entrepreneurship, others are imbued with the language of community, social capital and collective action. The existence of individualism and community within the same policy agenda may appear contradictory, yet it is suggested that neoliberalism brings together these two opposing discourses through a process of what Nikolas Rose calls ‘governing through community’. We explore how neoliberalism underpins community approaches to regional development in Australia, arguing that such strategies do little to counter the negative forces of globalisation in non-metropolitan parts of the country.

A framework of issues in large process modeling projects

As process management projects have increased in size due to globalised and company-wide initiatives, a corresponding growth in the size of process modeling projects can be observed. Despite advances in languages, tools and methodologies, several aspects of these projects have been largely ignored by the academic community. This paper makes a first contribution to a potential research agenda in this field by defining the characteristics of large-scale process modeling projects and proposing a framework of related issues. These issues are derived from a semi -structured interview and six focus groups conducted in Australia, Germany and the USA with enterprise and modeling software vendors and customers. The focus groups confirm the existence of unresolved problems in business process modeling projects. The outcomes provide a research agenda which directs researchers into further studies in global process management, process model decomposition and the overall governance of process modeling projects. It is expected that this research agenda will provide guidance to researchers and practitioners by focusing on areas of high theoretical and practical relevance.
