Screening, isolation, and decolonisation strategies in the control of meticillin resistant Staphylococcus aureus in intensive care units : cost effectiveness evaluation

Objective: To assess the cost-effectiveness of screening, isolation and decolonisation strategies in the control of methicillin-resistant Staphylococcus aureus (MRSA) in intensive care units (ICUs). Design: Economic evaluation. Setting: England and Wales. Population: ICU patients. Main outcome measures: Infections, deaths, costs, quality adjusted life years (QALYs), incremental cost-effectiveness ratios for alternative strategies, net monetary benefits (NMBs). Results: All strategies using isolation but not decolonisation improved health outcomes but increased costs. When MRSA prevalence on admission to the ICU was 5% and the willingness to pay per QALY gained was between £20,000 and £30,000, the best such strategy was to isolate only those patients at high risk of carrying MRSA (either pre-emptively or following identification by admission and weekly MRSA screening using chromogenic agar). Universal admission and weekly screening using polymerase chain reaction (PCR)-based MRSA detection coupled with isolation was unlikely to be cost-effective unless prevalence was high (10% colonised with MRSA on admission to the ICU). All decolonisation strategies improved health outcomes and reduced costs. While universal decolonisation (regardless of MRSA status) was the most cost-effective in the short-term, strategies using screening to target MRSA carriers may be preferred due to reduced risk of selecting for resistance. Amongst such targeted strategies, universal admission and weekly PCR screening coupled with decolonisation with nasal mupirocin was the most cost-effective. This finding was robust to ICU size, MRSA admission prevalence, the proportion of patients classified as high-risk, and the precise value of willingness to pay for health benefits. Conclusions: MRSA control strategies that use decolonisation are likely to be cost-saving in an ICU setting provided resistance is lacking, and combining universal PCR-based screening with decolonisation is likely to represent good value for money if untargeted decolonisation is considered unacceptable. In ICUs where decolonisation is not implemented there is insufficient evidence to support universal MRSA screening outside high prevalence settings.

Waves for change : the role of the South Tarawa-based women's interests program in the decolonisation process of the Gilbert Islands

This thesis has created a space for women in the history of the decolonisation of the Gilbert Islands. It traces the historical development of the national women's interests program in the Republic of Kiribati (formerly of the Gilbert and Ellice Islands Colony (GEIC)) as it was implemented through a network of women's clubs during the 1960s and 1970s. This thesis has provided the first history and interpretation of the Indigenous women's interests movement as it impacted the Gilbert Islands. It offers a narrative of the movement in terms of three overlapping waves of women leaders, based on an analysis of fieldwork, archival research and interviews conducted on South Tarawa, Kiribati.

Efficacy of a standard meticillin-resistant Staphylococcus aureus decolonisation protocol in routine clinical practice

Summary

Decolonisation may reduce the risk of meticillin-resistant Staphylococcus aureus (MRSA) infection in individual carriers and prevent transmission to other patients. The aims of this prospective cohort study were to determine the long-term efficacy of a standardised decolonisation regimen and to identify factors associated with failure. Patients colonised with MRSA underwent decolonisation, which was considered to be successful if there was no growth in three consecutive sets of site-specific screening swabs obtained weekly post treatment. If patients were successfully decolonised, follow-up cultures were performed 6 and 12 months later. Of 137 patients enrolled, 79 (58%) were successfully decolonised. Of these 79, 53 (67%) and 44 (56%) remained decolonised at 6 and 12 months respectively. Therefore only 44/137 (32%) patients who completed decolonisation were MRSA negative 12 months later. Outcome was not associated with a particular strain of MRSA. Successful decolonisation was less likely in patients colonised with a mupirocin-resistant isolate (adjusted odds ratio: 0.08; 95% confidence interval: 0.02–0.30), in patients with throat colonisation (0.22; 0.07–0.68) and in patients aged >80 years (0.30; 0.10–0.93) compared with those aged 60–80 years. These findings suggest that although initially successful in some cases, the protocol used did not result in long-term clearance of MRSA carriage for most patients.

'Against the tide': Australian government attitudes to decolonisation in the South Pacific, 1962-1972

This article is a study of the attitudes of Australian government ministers and officials towards the decolonisation of the Pacific island colonial territories in the decade from 1962 to 1972. It argues that the Australian state was very slow to recognise and understand that the winds of change would also sweep through the South Pacific and see the emergence of many new island nations by 1980.

Men Between: The Role of Zambian Broadcasters in Decolonisation

This article traces the history of a group of Zambian broadcasters who established the first radio station in the country and made their mark on broadcasting for years to come. It describes their contribution to modern Zambian culture and to nationalist mobilisation. African broadcasters developed formats, ways of presenting and choices of music that appealed to Zambian listeners and established new, authentically local styles. While radio quickly established itself as an integral part of everyday life and culture in the colony, its effect was highly ambivalent. Broadcasters at the same time undermined and enforced the colonial project of using the medium as a transmitter of modernisation ideology. The article explores Thomas Turino’s characterisation of this team as ‘cosmopolitans’ and shows how they were influenced by BBC ideas of journalism and modernisation ideology. To do so, it analyses the relationships African broadcasters had with Europeans in senior positions and with colonial and postcolonial governments. This shared value system brought these Zambian broadcasters into conflict with the post-independence government and its plans to bureaucratise radio, despite their nationalist commitment and strong support for the United National Independence Party (UNIP) before independence.

Moving and dancing towards decolonisation in education: An example from an Indigenous Australian performance classroom

This paper explores the special type of thinking, moving and dancing place which is opened up for decolonisaton when students engage in an embodied pedagogical practice in Indigenous education. The author examines what decolonisation means in this context by describing the ways in which the curriculum, the students and teacher, and more generally the discipline of ethnomusicology itself, undergo a process to question, critique, and move aside the pedagogical script of colonialism in order to allow Indigenous ways of understanding music and dance to be presented, privileged and empowered. Key questions are: What is the relationship between embodiment and disembodiment and decolonisation and colonisation? In what ways is embodiment more than, or other than, the presence of moving bodies? In what ways is performativity an aspect of power/knowledge/subject formations? How can it be theorised? What could the pedagogical scripts of decolonisation look like?

The Reverend Setareki Tuilovoni: mobile pacific leader in the decolonisation era

Setareki Tuilovoni was made the first Indigenous president of the Fijian Methodist church in 1964. This paper gives a biographical account with particular focus on his experiences overseas and how these shaped his approach to creating a united Methodist church at home, and a united Christian fellowship throughout the Pacific by means of regional church bodies. Because Tuilovoni had been present in America and Africa at pivotal points in the struggles for civil rights and decolonisation, his ideas were shaped by his mobility, and this in turn influenced his work to redefine the church in a decolonising Pacific, paving the way for moderate voices in the postcolonial church.
