Regulating antimicrobial use within hospitals: A qualitative study. Infect Dis Health 2024; 29:81-90. [PMID: 38216402 DOI: 10.1016/j.idh.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 11/30/2023] [Accepted: 12/06/2023] [Indexed: 01/14/2024]
Abstract
OBJECTIVES To examine how regulatory structures and processes focused on antimicrobial stewardship and antimicrobial resistance are experienced by hospital managers and clinicians. METHODS Forty-two hospital managers and clinicians working within accreditation and antimicrobial stewardship teams in three Australian hospitals participated in individual in-depth interviews. Thematic analysis was performed. RESULTS Thematic analysis revealed participants' experiences of hospital antimicrobial regulation and their perceptions of what would be required for meaningful antimicrobial optimisation. Theme 1: Experience of regulation of antimicrobials within hospitals: Participants described an increased profile of antimicrobial resistance with inclusion in regulatory requirements, but also the risks of bureaucratic manoeuvring to meet standards rather than governance-inducing systemic changes. Theme 2: Growth of accreditation processes and hospitals over time: Both regulatory requirements and hospitals were described as evolving over time, each manoeuvring in response to each other (e.g. development of short notice accreditation). Theme 3: Perceived requirements for change: Participants perceived a need for top-down buy-in, resource prioritisation, complex understanding of power and influence on clinician behaviour, and a critical need for medical engagement. CONCLUSIONS This study around antimicrobials shows the tension and dynamic relationship between regulatory processes and hospital responses, bringing to light the enduring balance of a system that positions itself to meet regulatory requirements and emerging "demands", without necessarily addressing the key underlying concerns. Antimicrobial resistance-related solutions are perceived as likely to require further resourcing and buy-in across multiple levels, engagement across professional streams and require strategies that consider complex systems change in order for regulatory structures to have potency.

To swab or not to swab? A qualitative study of pathology testing, interpretation, and value in diabetes-related foot ulceration. Infect Dis Health 2024; 29:39-50. [PMID: 38016843 DOI: 10.1016/j.idh.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/30/2023] [Accepted: 10/01/2023] [Indexed: 11/30/2023]
Abstract
BACKGROUND Diagnostic testing has been proposed as a key strategy to tackle escalating antimicrobial resistance (AMR). However, effectiveness of testing is limited by the complexities of the hospital environment, including human factors. OBJECTIVES To examine swab-testing in diabetes-related foot infections as a case study of the factors impacting microbiology testing use, efficacy, and antimicrobial resistance. METHODS Seventeen clinicians involved in the management of diabetes-related foot infections, including podiatrists, nurses, and doctors, participated in in-depth individual interviews conducted by a qualitative researcher on the investigation and management of diabetes-related foot infections. Thematic analysis was performed. RESULTS The multilayered and evolving features of the human-diagnostic interface were described by participants as potential barriers to effective swab-testing in clinical care, including diagnostic training and interpretation deficits; communication difficulties; interpretation deficits and diagnostic assumptions; the influence of inter-professional dynamics; and flow-on consequences for patient decisions and care. CONCLUSIONS Swab-testing has been used for over 100 years, and yet there remain substantial factors that limit their effective use in clinical practice as demonstrated by this study. A focus on upscaling diagnostic testing, particularly with escalating AMR, without considering complex implementation and human factors is likely to have limited impact on practice improvement. This study identified vulnerability points in the human-diagnostic interaction which should be considered in the implementation of other microbiological tests. This study on the simple wound swab has implications for future diagnostic upscaling and investment, including its role in address antimicrobial resistance.

Abstract
OBJECTIVES Australia has made significant progress towards achieving the UNAIDS's 95-95-95 cascade targets including HIV viral suppression. To investigate the burden of HIV viraemia, we assessed viral blips, low-level viraemia (LLV) and virologic failure (VF) in an Australian cohort. METHODS We studied the proportion of people with viral suppression, viral blips, LLV and VF in the Australian HIV observational database (AHOD) between 2010 and 2021. The association between blips or LLV, and VF was investigated using Cox regression, and predictors of viral blips and LLV were assessed using repeated-measured logistic regression. RESULTS Among 2544 AHOD participants who were in follow-up and on antiretroviral therapy (ART) from 1 January 2010 (88.7% male), 444 had experienced VF (incidence rate: 2.45 [95% CI: 2.23-2.69] per 100 person-years [PY]) during 18,125 PY of follow-up (a median of 7.6 years). The proportion of people with VF decreased over time, whereas rates of blips and LLV remained stable. Participants with blips (hazard ratio, 2.89; 95% CI: 2.31-3.61) and LLV (4.46; 95% CI: 3.38-5.89) were at increased risk of VF. Hepatitis B co-infection, longer documented treatment interruption duration, younger age and lower CD4 at ART initiation, and protease inhibitors-based initial regimen were associated with an increased risk of VF. Common predictors of blips and LLV such as higher HIV-1 RNA and lower CD4 at ART initiation, longer treatment interruption, more VL testing and types of care settings (hospitals vs. sexual health services) were identified. CONCLUSIONS Blips and LLV predict subsequent VF development. We identified important predictors of HIV viraemia including VF among individuals on INSTI-based regimens to help direct HIV management plans.

Nursing experiences in antimicrobial optimisation in the intensive care unit: A convergent analysis of a national survey. Aust Crit Care 2023; 36:769-781. [PMID: 36404269 DOI: 10.1016/j.aucc.2022.09.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Revised: 09/08/2022] [Accepted: 09/08/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Recent evidence highlights the need for an interdisciplinary approach to antimicrobial stewardship (AMS). Nursing involvement in optimising antimicrobials in the intensive care unit (ICU) remains understudied. OBJECTIVE The objective of this study was to explore nurses' perceptions and experiences of antimicrobial optimisation or stewardship in ICUs in Australia. METHODS An anonymous web-based survey was deployed nationally in early 2021 through two ICU nursing networks. Associations between survey responses were analysed descriptively and by using nonparametric tests (with statistical significance established at p ≤ 0.05). Free-text survey responses underwent qualitative thematic analysis. Interpretation and reporting of quantitative and qualitative data were integrated. RESULTS A total of 226 ICU nurses completed the survey. The majority (197/226; 87%) responded that lack of education limits engagement in AMS. Only 13% (30/226) reported the presence of AMS education and training for nurses in their ICUs. Only about half (108/226; 48%) of the nurses were confident to question prescribers when they considered that the antimicrobial prescribed was unnecessary, with nurses in senior roles more likely to do so than nurses providing bedside care (p < 0.05). Gaps in education (including unfamiliarity with AMS roles), noninclusive antimicrobial discussions, moral distress, and potential workload burden were seen as potential barriers/challenges to engagement. CONCLUSION The multifactorial barriers identified that inhibit nurses from performing AMS tasks could be addressed by strengthening interprofessional education at all levels and by applying practical AMS interventions that are inclusive for nursing participation. A purposeful culture change that fosters psychological safety and collaborative practice is paramount to supporting nurses in these roles.

Multidisciplinary team meetings in prosthetic joint infection management: A qualitative study. Infect Dis Health 2023; 28:145-150. [PMID: 36788048 DOI: 10.1016/j.idh.2023.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 11/30/2022] [Accepted: 01/15/2023] [Indexed: 02/16/2023]
Abstract
BACKGROUND Prosthetic joint infections (PJIs) cause substantial morbidity to patients and are extremely challenging for clinicians. Their management can include multiple operations, antibiotics, and prolonged hospital admissions. Multidisciplinary team meetings (MDTM) are increasingly used for collaborative decision-making around the management of PJIs, but thus far there has been no examination of the role of MDTM in decisions and management. This study aimed to examine interactions in a PJI MDTM to identify the dynamics in decision-making, and inter-specialty relationships more broadly. METHODS Twelve MDTMs over 7 months at an Australian tertiary referral hospital were video recorded, transcribed, and thematic analysis was performed. RESULTS Thematic analysis revealed four key areas of collaborative discussion 1. Achieving Inter-specialty Balance: The role of the multidisciplinary team discussion in providing balance between specialty views, and traversing the barriers between specialty interactions. 2. Negotiating Grey zones: there was frequent discussion of the limits of tests, interpretation of symptoms, and the limits of proposed operative strategies, and the resultant tensions of balancing ideal care vs pragmatic decision-making, and divergent goals of care. 3. Tailoring Treatment: identification of individual patient factors (both physiological and behavioural) and risks into collaborative decision-making. 4. Affording Failure: creating affordances in communication to openly discuss 'failure' to eliminate infection and likely negative outcomes. CONCLUSIONS MDTM in the management of prosthetic joint infections serve multiple functions including: achieving interdisciplinary balance; effective grey zone management, tailoring reconfigured care; and most critically, recognition of 'failure' to eliminate infection, a communicative affordance most likely leading to better care.

Abstract
Coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus is likely to remain endemic globally despite widespread vaccination. There is increasing concern for myocardial involvement and ensuing cardiac complications due to COVID-19, however, the available evidence suggests these risks are low. Pandemic publishing has resulted in rapid manuscript availability though pre-print servers. Subsequent article retractions, a lack of standardised definitions, over-reliance on isolated troponin elevation and the heterogeneity of studied patient groups (i.e. severe vs. symptomatic vs all infections) resulted in early concern for high rates of myocarditis in patients with and recovering from COVID-19. The estimated incidence of myocarditis in COVID-19 infection is 11 cases per 100,000 infections compared with an estimated 2.7 cases per 100,000 persons following mRNA vaccination. For substantiated cases, the clinical course of myocarditis related to COVID-19 or mRNA vaccination appears mild and self-limiting, with reports of severe/fulminant myocarditis being rare. There is limited data available on the management of myocarditis in these settings. Clinical guidance for appropriate use of cardiac investigations and monitoring in COVID-19 is needed for effective risk stratification and efficient use of cardiac resources in Australia. An amalgamation of national and international position statements and guidelines is helpful for guiding clinical practice. This paper reviews the current available evidence and guidelines and provides a summary of the risks and potential use of cardiac investigations and monitoring for patients with COVID-19.

Abstract
BACKGROUND Patients undergoing haemodialysis colonised with multi-drug resistant organisms (MDROs) are commonly managed with transmission-based precautions (TBP) to prevent nosocomial transmission. TBP have been linked to mixed effects on patient psychological well-being and clinical care. This study was designed to report the lived experience of dialysis patients managed with TBP. METHODS A qualitative study of 15 patients undergoing haemodialysis managed with TBP was performed. Participants took part in individual semi-structured interviews. Data was analysed utilising an interpretive phenomenological approach. RESULTS Four themes were identified. 1. Communication of what MDRO screening meant, the results, and implications of MDRO positivity was perceived by many patients as insufficient and inconsistent. 2. Experiences of care in isolation were described, with both positive (privacy) and negative (reduced interaction) experiences identified. 3. Psychosocial and emotional responses including concern about health implications and stigma were reported, but also screening was described by some as increasing their perception of being cared for by health care workers, as they felt all health risks were being managed. 4. Confusion around perceived inconsistencies of management, particularly across different environments (eg hospital vs home) and staff. CONCLUSION TBP have complex positive and negative impacts on patients which should be considered when developing MDRO management policy and communication around such policy. Strategies to improve communication, patient and staff education, and remove (or explain) perceived inconsistencies of practice may reduce the negative consequences of TBP leading to improved delivery of quality, person-centred care.

"One minute it's an airborne virus, then it's a droplet virus, and then it's like nobody really knows…": Experiences of pandemic PPE amongst Australian healthcare workers. Infect Dis Health 2022; 27:71-80. [PMID: 34836839 PMCID: PMC8610373 DOI: 10.1016/j.idh.2021.10.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 10/05/2021] [Accepted: 10/31/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND The SARS-CoV-2 pandemic has challenged health systems globally. A key controversy has been how to protect healthcare workers (HCWs) using personal protective equipment (PPE). METHODS Interviews were performed with 63 HCWs across two states in Australia to explore their experiences of PPE during the SARS-CoV-2 pandemic. Thematic analysis was performed. RESULTS Four themes were identified with respect to HCWs' experience of pandemic PPE: 1. Risk, fear and uncertainty: HCWs experienced considerable fear and heightened personal and professional risk, reporting anxiety about the adequacy of PPE and the resultant risk to themselves and their families. 2. Evidence and the ambiguities of evolving guidelines: forms of evidence, its interpretation, and the perception of rapidly changing guidelines heightened distress amongst HCWs. 3. Trust and care: Access to PPE signified organisational support and care, and restrictions on PPE use were considered a breach of trust. 4. Non-compliant practice in the context of social upheaval: despite communication of evidence-based guidelines, an environment of mistrust, personal risk, and organisational uncertainty resulted in variable compliance. CONCLUSION PPE preferences and usage offer a material signifier of the broader, evolving pandemic context, reflecting HCWs' fear, mistrust, sense of inequity and social solidarity (or breakdown). PPE therefore represents the affective (emotional) demands of professional care, as well as a technical challenge of infection prevention and control. If rationing of PPE is necessary, policymakers need to take account of how HCWs will perceive restrictions or conflicting recommendations and build trust through effective communication (including of uncertainty).

Experiences of the SARS-CoV-2 pandemic amongst Australian healthcare workers: from stressors to protective factors. J Hosp Infect 2022; 121:75-81.

Abstract
BACKGROUND The SARS-CoV-2 pandemic has critically challenged healthcare systems globally. Examining the experiences of healthcare workers (HCWs) is important for optimizing ongoing and future pandemic responses. OBJECTIVES In-depth exploration of Australian HCWs' experiences of the SARS-CoV-2 pandemic, with a focus on reported stressors vis-à-vis protective factors. METHODS Individual interviews were performed with 63 HCWs in Australia. A range of professional streams and operational staff were included. Thematic analysis was performed. RESULTS Thematic analysis identified stressors centred on paucity of, or changing, evidence, leading to absence of, or mistrust in, guidelines; unprecedented alterations to the autonomy and sense of control of clinicians; and deficiencies in communication and support. Key protective factors included: the development of clear guidance from respected clinical leaders or recognized clinical bodies, interpersonal support, and strong teamwork, leadership, and a sense of organizational preparedness. CONCLUSIONS This study provides insights into the key organizational sources of emotional stress for HCWs within pandemic responses and describes experiences of protective factors. HCWs experiencing unprecedented uncertainty, fear, and rapid change, rely on clear communication, strong leadership, guidelines endorsed by recognized expert groups or individuals, and have increased reliance on interpersonal support. Structured strategies for leadership and communication at team, service group and organizational levels, provision of psychological support, and consideration of the potential negative effects of centralizing control, would assist in ameliorating the extreme pressures of working within a pandemic environment.

Abstract
OBJECTIVES Despite escalating antimicrobial resistance (AMR), implementing effective antimicrobial optimisation within healthcare settings has been hampered by institutional impediments. This study sought to examine, from a hospital management and governance perspective, why healthcare providers may find it challenging to enact changes needed to address rising AMR. DESIGN Semistructured qualitative interviews around their experiences of antimicrobial stewardship (AMS) and responsiveness to the requirement for optimisation. Data were analysed using the framework approach. SETTING Two metropolitan tertiary-referral hospitals in Australia. PARTICIPANTS Twenty hospital managers and executives from the organisational level of department head and above, spanning a range of professional backgrounds and in both clinical and non-clinical roles, and different professional streams were represented. RESULTS Thematic analysis demonstrated three key domains which managers and executives describe, and which might function to delimit institutional responsiveness to present and future AMR solutions. First, the primacy of 'political' priorities. AMR was perceived as a secondary priority, overshadowed by political priorities determined beyond the hospital by state health departments/ministries and election cycles. Second, the limits of accreditation as a mechanism for change. Hospital accreditation processes and regulatory structures were not sufficient to induce efficacious AMS. Third, a culture of acute problem 'solving' rather than future proofing. A culture of reactivity was described across government and healthcare institutions, precluding longer term objectives, like addressing the AMR crisis. CONCLUSION There are dynamics between political and health service institutions, as well as enduring governance norms, that may significantly shape capacity to enact AMS and respond to AMR. Until these issues are addressed, and the field moves beyond individual behaviour modification models, antimicrobial misuse will likely continue, and stewardship is likely to have a limited impact.

Abstract
The COVID-19 pandemic continues to highlight both global interconnectedness and schisms across place, context and peoples. While countries such as Australia have securitised their borders in response to the global spread of disease, flows of information and collective affect continue to permeate these boundaries. Drawing on interviews with Australian healthcare workers, we examine how their experiences of the pandemic are shaped by affect and evidence ‘traveling’ across time and space. Our analysis points to the limitations of global health crisis responses that focus solely on material risk and spatial separation. Institutional responses must, we suggest, also consider the affective and discursive dimensions of health-related risk environments.

Abstract
OBJECTIVES To assess an intervention for surgical antibiotic prophylaxis (SAP) improvement within surgical teams focused on addressing barriers and fostering enablers and ownership of guideline compliance. DESIGN The Queensland Surgical Antibiotic Prophylaxis (QSAP) study was a multicentre, mixed methods study designed to address barriers and enablers to SAP compliance and facilitate engagement in self-directed audit/feedback and assess the efficacy of the intervention in improving compliance with SAP guidelines. The implementation was assessed using a 24-month interrupted time series design coupled with a qualitative evaluation. SETTING The study was undertaken at three hospitals (one regional, two metropolitan) in Australia. PARTICIPANTS SAP-prescribing decisions for 1757 patients undergoing general surgical procedures from three health services were included. Six bimonthly time points, pre-implementation and post implementation of the intervention, were measured. Qualitative interviews were performed with 29 clinical team members. SAP improvements varied across site and time periods. INTERVENTION QSAP embedded ownership of quality improvement in SAP within surgical teams and used known social influences to address barriers to and enablers of optimal SAP prescribing. RESULTS The site that reported senior surgeon engagement showed steady and consistent improvement in prescribing over 24 months (prestudy and poststudy). Multiple factors, including resource issues, influenced engagement and sites/time points where these were present had no improvement in guideline compliance. CONCLUSIONS The barriers-enablers-ownership model shows promise in its ability to facilitate prescribing improvements and could be expanded into other areas of antimicrobial stewardship. Senior ownership was a predictor of success (or failure) of the intervention across sites and time periods. The key role of senior leaders in change leadership indicates the critical need to engage other specialties in the stewardship agenda. The influence of contextual factors in limiting engagement clearly identifies issues of resource distributions/inequalities within health systems as limiting antimicrobial optimisation potential.

Abstract
There is an urgent and recognized need for an interprofessional collaborative approach to support global action in addressing antimicrobial resistance (AMR). Antimicrobial stewardship (AMS) refers to systematic approaches for antimicrobial optimization within healthcare organizations. In areas with high antimicrobial utilization such as intensive care units (ICUs), specific roles for nurses in AMS are not clearly defined. This review aimed to identify and to critically evaluate primary studies that examined knowledge, perspectives and experiences of nurses associated with antimicrobial use and optimization in ICUs. A systematic search of Medline, CINAHL, PsychINFO, EMBASE, PubMed, SCOPUS, Cochrane Library and Web of Science databases for primary studies published from 1st January 2000 to 20th March 2020 was performed. A convergent synthesis design was used to synthesize quantitative and qualitative data. Of the 898 studies initially screened, 26 were included. Most (18/26) studies were quantitative. All qualitative studies (6/26) were of high methodological quality. Studies where interventions were used (10/26) identified significant potential for ICU nurses to reduce antimicrobial use, time-to-antibiotic administration, and error rates. Barriers to nursing engagement included knowledge deficits in antimicrobial use, interprofessional dissonance and the culture of deference to physicians. Enhancing education, technology utilization, strong nursing leadership and robust organizational structures that support nurses were perceived as enablers to strengthen their roles in optimizing antimicrobial use. This review showed that nursing initiatives have significant potential to strengthen antimicrobial optimization in ICUs. Barriers and enablers to active engagement were identified.

Abstract
India and the global community are facing a critical crisis of antimicrobial resistance (AMR), significantly contributed to by on-going and increasing antimicrobial misuse. Information as to what drives misuse of antimicrobials within India is essential to inform strategies to address the crisis. This papers aims to identify perceived influences on antimicrobial use in Hyderabad, India. We conducted semi-structured qualitative interviews conducted with thirty participants (15 doctors, 15 pharmacists) around their experiences of antimicrobials in Hyderabad, India. Thematic analysis was performed and four themes identified around (1) Perceptions of the problem of resistance and antimicrobial use; (2) Social pressures to prescribe/dispense; (3) Financial pressures driving antimicrobial over-use; and (4) Lack of regulation around training and qualifications. We conclude that antimicrobial use within India is embedded with, and occurs as a result of, complex social and economic factors including issues of resource limitation, structural/governance limitations and social relationships. Strategies to address misuse without acknowledging and addressing the critical driving forces of use will be unlikely to induce significant change.

OBJECTIVES This study responds to calls for greater focus on nursing roles, and the need for nursing integration within the antimicrobial optimisation agenda. The objective of this study was to explore Australian hospital nurses' views on antimicrobial resistance and antimicrobial stewardship (AMS) in a hospital setting, in order to better understand the opportunities for and challenges to integration of nursing staff in antimicrobial optimisation within hospital settings. DESIGN Qualitative one-on-one, semistructured interviews. Interview transcripts were digitally audio-recorded and transcribed verbatim. Data were subject to thematic analysis supported by the framework approach and informed by sociological methods and theory. SETTING Four hospitals (three public and one private), across metropolitan, regional and remote areas, in two Australian states. PARTICIPANTS 86 nurses (77 females, 9 males), from a range of hospital departments, at a range of career stages. RESULTS Findings were organised into three thematic domains: (1) the current peripheral role of nurses in AMS; (2) the importance of AMS as a collaborative effort, and current tensions around interprofessional roles and (3) how nurses can bolster antimicrobial optimisation within AMS and beyond. CONCLUSION Nursing staff are central to infection management within the hospital and are thus ideally located to enhance antibiotic optimisation and contribute to AMS governance. However, without increased interprofessional cooperation, education and integration in the AMS agenda, as well as addressing organisational/resource constraints in the hospital, the nursing role in stewardship will remain limited.

The drivers of antimicrobial use across institutions, stakeholders and economic settings: a paradigm shift is required for effective optimization. J Antimicrob Chemother 2020; 74:2803-2809. [PMID: 31169902 DOI: 10.1093/jac/dkz233] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Revised: 05/02/2019] [Accepted: 05/02/2019] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVES Significant antimicrobial overuse persists worldwide, despite overwhelming evidence of antimicrobial resistance and knowledge that optimization of antimicrobial use will slow the development of resistance. It is critical to understand why this occurs. This study aims to consider the social influences on antimicrobial use within hospitals in Australia, via an in-depth, multisite analysis. METHODS We used a qualitative multisite design, involving 222 individual semi-structured interviews and thematic analysis. Participants (85 doctors, 79 nurses, 31 pharmacists and 27 hospital managers) were recruited from five hospitals in Australia, including four public hospitals (two metropolitan, one regional and one remote) and one private hospital. RESULTS Analysis of the interviews identified social relationships and institutional structures that may have a strong influence on antimicrobial use, which must be addressed concurrently. (i) Social relationships that exist across settings: these include the influence of personal risk, hierarchies, inter- and intraprofessional dynamics and sense of futility in making a difference long term in relation to antimicrobial resistance. (ii) Institutional structures that offer context-specific influences: these include patient population factors (including socioeconomic factors, geographical isolation and local infection patterns), proximity and resource issues. CONCLUSIONS The success of antimicrobial optimization rests on adequate awareness and incorporation of multilevel influences. Analysis of the problem has tended to emphasize individual 'behaviour improvement' in prescribing rather than incorporating the problem of overuse as inherently multidimensional and necessarily incorporating personal, interpersonal and institutional variables. A paradigm shift is urgently needed to incorporate these critical factors in antimicrobial optimization strategies.

Aerosol-generating procedures and infective risk to healthcare workers from SARS-CoV-2: the limits of the evidence. J Hosp Infect 2020; 105:717-725. [PMID: 32497651 PMCID: PMC7263217 DOI: 10.1016/j.jhin.2020.05.037] [Citation(s) in RCA: 83] [Impact Index Per Article: 20.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 05/26/2020] [Indexed: 01/12/2023]
Abstract
The transmission behaviour of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is still being defined. It is likely that it is transmitted predominantly by droplets and direct contact and it is possible that there is at least opportunistic airborne transmission. In order to protect healthcare staff adequately it is necessary that we establish whether aerosol-generating procedures (AGPs) increase the risk of transmission of SARS-CoV-2. Where we do not have evidence relating to SARS-CoV-2, guidelines for safely conducting these procedures should consider the risk of transmitting related pathogens. Currently there is very little evidence detailing the transmission of SARS-CoV-2 associated with any specific procedures. Regarding AGPs and respiratory pathogens in general, there is still a large knowledge gap that will leave clinicians unsure of the risk to themselves when offering these procedures. This review aimed to summarize the evidence (and gaps in evidence) around AGPs and SARS-CoV-2.

Abstract
Coxiella burnetii infection is not known to involve directly the kidneys. Kidney injury associated with Q fever usually manifests in the setting of chronic infection or endocarditis with development of immune complex deposition. Acute kidney injury (AKI) in the context of acute Q fever infection may be more pathologically heterogeneous. We describe two cases of severe AKI secondary to acute Q fever infection, each with marked differences in pathological characteristics, and clinical course.

Abstract
Diarrhoea that occurs during or after recent travel is predominantly infectious in nature; however, in atypical or prolonged cases a broader range of aetiologies for diarrhoea must be considered, and a careful history and examination may reveal clues to more sinister causes of diarrhoea. We report two cases in which a recent travel history and a positive stool culture or polymerase chain reaction testing for bacterial pathogens delayed the diagnosis of ulcerative colitis. As a result of severe inflammatory bowel disease, colectomy was the final result in both cases. Early consideration of causes other than infection for traveller's diarrhoea may prevent unnecessary morbidity in young patients.

Why is optimisation of antimicrobial use difficult at the end of life? Intern Med J 2019; 49:269-271.

Abstract
The antibiotic optimisation imperative is now ubiquitous, with national policy frameworks in Organisation for Economic Co-operation and Development (OECD) countries incorporating the requirement for antimicrobial stewardship within healthcare services. Yet in practice, the optimisation agenda often raises complex ethical- and practice-based dilemmas. Antibiotic use at the end of life is multidimensional. It includes balancing complex issues, such as accuracy of prognostic estimates, benevolence to the individual versus the broader public health, personalised value judgement of time and quality of life and the right to treatment versus the right to die. It also occurs in an emotional context where the clinician and patient (and their family) collectively confront mortality. This provides a scenario where amplification of the already strong social and behavioural forces that drive overuse of antibiotics in many other clinical settings may occur. It therefore offers an important case for illustrating how antibiotic optimisation may be limited by social, value-based and ethical dilemmas.

Abstract
Abstract
A multilaboratory study was conducted to compare the automated BAX® system and the standard cultural methods for detection of Listeria monocytogenes in foods. Six food types (frankfurters, soft cheese, smoked salmon, raw, ground beef, fresh radishes, and frozen peas) were analyzed by each method. For each food type, 3 inoculation levels were tested: high (average of 2 CFU/g), low (average of 0.2 CFU/g) and uninoculated controls. A total of 25 laboratories representing government and industry participated. Of the 2335 samples analyzed, 1109 were positive by the BAX system and 1115 were positive by the standard method. A Chi square analysis of each of the 6 food types, at the 3 inoculation levels tested, was performed. For all foods, except radishes, the BAX system performed as well as or better than the standard reference methods based on the Chi square results.

Abstract
BACKGROUND Australia has unrestricted access to direct-acting antivirals (DAA) for hepatitis C virus (HCV) treatment. In order to increase access to treatment, primary care providers are able to prescribe DAA after fibrosis assessment and specialist consultation. Transient elastography (TE) is recommended prior to commencement of HCV treatment; however, TE is rarely available outside secondary care centres in Australia and therefore a requirement for TE could represent a barrier to access to HCV treatment in primary care. OBJECTIVES In order to bridge this access gap, we developed a community-based TE service across the Sunshine Coast and Wide Bay areas of Queensland. DESIGN Retrospective analysis of a prospectively recorded HCV treatment database. INTERVENTIONS A nurse-led service equipped with two mobile Fibroscan units assesses patients in eight locations across regional Queensland. Patients are referred into the service via primary care and undergo nurse-led TE at a location convenient to the patient. Patients are discussed at a weekly multidisciplinary team meeting and a treatment recommendation made to the referring GP. Treatment is initiated and monitored in primary care. Patients with cirrhosis are offered follow-up in secondary care. RESULTS 327 patients have undergone assessment and commenced treatment in primary care. Median age 48 years (IQR 38-56), 66% male. 57% genotype 1, 40% genotype 3; 82% treatment naïve; 10% had cirrhosis (liver stiffness >12.5 kPa). The majority were treated with sofosbuvir-based regimens. 26% treated with 8-week regimens. All patients had treatment prescribed and monitored in primary care. Telephone follow-up to confirm sustained virological response (SVR) was performed by clinic nurses. 147 patients remain on treatment. 180 patients have completed treatment. SVR data were not available for 19 patients (lost to follow-up). Intention-to-treat SVR rate was 85.5%. In patients with complete data SVR rate was 95.6%. CONCLUSION Community-based TE assessment facilitates access to HCV treatment in primary care with excellent SVR rates.

Antimicrobial use in patients at the end of life in an Australian hospital. Infect Dis Health 2019; 24:92-97.

Abstract
BACKGROUND Antimicrobial resistance is increasing and there is an urgent international imperative to optimise use within hospitals. Antibiotic use at the end of life is frequent in the hospital setting, but data on use in Australian hospitals in this context is limited, and optimisation is complicated by clinical/diagnostic, ethical and humanistic considerations. As yet there is little data available on baseline use in hospital end of life settings, an empirical gap we sought to begin to fill here. METHODS A retrospective review of antibiotic use in patients who died in a Queensland hospital between January 2015 and July 2015. RESULTS One hundred and thirty-seven patients were included, of which 73 were male (53.3%) and the median age was 81 years. Of these patients, 86 received antibiotics at the end of life. The most common antibiotic prescribed was piperacillin/tazobactam (41.9%). The most common site of infection was pulmonary (32.8%). Of 86 patients prescribed antibiotics, 29 patients (33.7%) received antibiotics after futility was documented. 83 patients (96.5%) were administered their antibiotics intravenously. CONCLUSION Antimicrobial use at the end of life is frequent, with greater than one third of the patients who died in hospital having their antibiotics continued after discussion of futility. Antimicrobial use in this setting is complex with significant clinical, social and ethical considerations which need to be addressed if antibiotic optimization in this area (and more broadly in the hospital) is to be achieved.

Abstract
UNLABELLED Background Gender differences vary across geographical settings and are poorly reported in the literature. The aim of this study was to evaluate demographics and clinical characteristics of participants from the Australian HIV Observational Database (AHOD), and to explore any differences between females and males in the rate of new clinical outcomes, as well as initial immunological and virological response to antiretroviral therapy. METHODS Time to a new clinical end-point, all-cause mortality and/or AIDS illness was analysed using standard survival methods. Univariate and covariate adjusted Cox proportional hazard models were used to evaluate the time to plasma viral load suppression in all patients that initiated antiretroviral therapy (ART) and time to switching from a first-line ART to a second-line ART regimen. RESULTS There was no significant difference between females and males for the hazard of all-cause mortality [adjusted hazard ratio: 0.98 (0.51, 1.55), P=0.67], new AIDS illness [adjusted hazard ratio: 0.75 (0.38, 1.48), P=0.41] or a composite end-point [adjusted hazard ratio: 0.74 (0.45, 1.21), P=0.23]. Incident rates of all-cause mortality were similar between females and males; 1.14 (0.61, 1.95) vs 1.28 (1.12, 1.45) per 100 person years. Virological response to ART was similar for females and males when measured as time to viral suppression and/or time to virological failure. CONCLUSION This study supports current Australian HIV clinical care as providing equivalent standards of care for male and female HIV-positive patients. Future studies should compare ART-associated toxicity differences between ART-associated toxicity differences between men and women living with HIV in Australia.

Abstract
PURPOSE Surgical antibiotic prophylaxis (SAP) is a common area of antimicrobial misuse. The aim of this study was to explore the social dynamics that influence the use of SAP. METHODS 20 surgeons and anaesthetists from a tertiary referral hospital in Australia participated in semi-structured interviews focusing on experiences and perspectives on SAP prescribing. Interview data were analysed using the framework approach. RESULTS Systematic analysis of the participants' account of the social factors influencing SAP revealed four themes. First, antibiotic prophylaxis is treated as a low priority with the competing demands of the operating theatre environment. Second, whilst guidelines have increased in prominence in recent years, there exists a lack of confidence in their ability to protect the surgeon from responsibility for infectious complications (thus driving SAP over-prescribing). Third, non-concordance prolonged duration of SAP is perceived to be driven by benevolence for the individual patient. Finally, improvisation with novel SAP strategies is reported as ubiquitous, and acknowledged to confer a sense of reassurance to the surgeon despite potential non-concordance with guidelines or clinical efficacy. CONCLUSIONS Surgical-specific concerns have thus far not been meaningfully integrated into antimicrobial stewardship (AMS) programmes, including important dynamics of confidence, trust and mitigating fear of adverse infective events. Surgeons require specific forms of AMS support to enact optimisation, including support for strong collaborative ownership of the surgical risk of infection, and intra-specialty (within surgical specialties) and inter-specialty (between surgery, anaesthetics and infectious diseases) intervention strategies to establish endorsement of and address barriers to guideline implementation.

Abstract
BACKGROUND Antimicrobial therapy for intra-abdominal infections is often inappropriately prolonged. An intervention addressing factors influencing the duration of intravenous antibiotic use was undertaken. This study reports the antibiotic prescribing patterns before and after the intervention and a qualitative analysis of the experience of the intervention. METHODS Quantitative: A retrospective audit of patients with complicated intra-abdominal infection before and after a multifaceted persuasive intervention was performed. Qualitative: Semi-structured interviews were performed to evaluate which elements of the intervention were perceived to be effective. RESULTS An intervention including collaborative inter-specialty and inter-professional educational meetings, and education of all professional streams was undertaken. Quantitative: Twenty-three patients before and 22 patients after the intervention were included. The total duration of antibiotics decreased significantly following the intervention (9.2 versus 6.6 days P = 0.02). The duration of intravenous antibiotics did not change significantly (5.4 versus 4.5 days, P = 0.06). Qualitative: Eighteen health-care professionals participated. Thematic analysis indicated that a collaborative approach between senior surgical and infectious disease specialists in the pre-intervention stage led to perceived ownership and leadership of the intervention by the surgical team, which was thought critical to the success of the intervention. Conversely, the ability of nurses and pharmacists to influence antibiotic practice was considered limited and a poster promoting the intervention was perceived as ineffective. CONCLUSION Consultant leadership and specialty ownership of the process were perceived to be critical in the success of the intervention. Antibiotic stewardship programs which address social factors may have greater efficacy to optimize antimicrobial prescribing.

Abstract
Given the global crisis of antimicrobial resistance, the continued misuse of antibiotics is perplexing, particularly despite persistent attempts to curb usage. This issue extends beyond traditional "wastage" areas, of livestock and community medicine, to hospitals, raising questions regarding the current principles of hospital practice. Drawing on five focus group discussions, we explore why doctors act in the ways they do regarding antibiotics, revealing how practices are done, justified, and perpetuated. We posit that antibiotic misuse is better understood in terms of social relations of fear, survival and a desire for autonomy; everyday rituals, performances, and forms of professional etiquette; and the mixed obligations evident in the health sector. Moreover, that antibiotic misuse presents as a case study of the broader problematic of defensive medicine. We argue that the impending global antibiotic crisis will involve understanding how medicine is built around certain logics of practice, many that are highly resistant to change.

Abstract
We are likely moving rapidly toward a post-antibiotic era, as a result of escalating antimicrobial resistance, rapidly declining antibiotic production and profligate overuse. Hitherto research has almost exclusively focused on doctors' prescribing, with nurses' roles in antibiotic use remaining virtually invisible. Drawing on interviews with 30 nurses, we focus on nurses as brokers of doctors' antibiotic decisions, nursing capacity to challenge doctors' decisions, and, "back stage" strategies for circumnavigating organizational constraints. We argue that nurses occupy an essential and conscious position as brokers within the hospital; a subject position that is not neutral, facilitates (short-term) cohesion, and involves the pursuit of particular (preferred) nursing outcomes. Illustrating how authority can be diffuse, mediated by institutionalized praxis, and how professionals evade attempts to govern their practice, we challenge the reification of physician prescribing power, arguing that it may work against the utilization of nurses as important stakeholders in the future of antibiotics.

Abstract
Antibiotic resistance poses a significant global threat, yet clinically inappropriate antibiotic use within hospitals continues despite the implementation of abatement strategies. Antibiotic use and the viability of existing antibiotic options now sit precariously at the nexus of political will, institutional governance and clinical priorities ‘at the bedside’. Yet no study has hitherto explored the perspectives of managers, instead of focusing on clinicians. In this article, drawing on qualitative interviews with hospital managers, we explore accounts of responding to antimicrobial resistance, managing antibiotic governance and negotiating clinical and managerial priorities. We argue that the managers’ accounts articulate the problematic nexus of measurement and accountability, the downflow effects of political will, and core tensions within the hospital between moral, managerial and medical authority. We apply Bourdieu’s theory of practice to argue that an understanding of the logics of practice within the ‘hospital management classes’ will be critical in efforts to protect antibiotics for future generations.

Abstract
BACKGROUND Antibiotic optimization in hospitals is an increasingly critical priority in the context of proliferating resistance. Despite the emphasis on doctors, optimizing antibiotic use within hospitals requires an understanding of how different stakeholders, including non-prescribers, influence practice and practice change. AIM This study was designed to understand Australian hospital managers' perspectives on antimicrobial resistance, managing antibiotic governance, and negotiating clinical vis-à-vis managerial priorities. METHODS Twenty-three managers in three hospitals participated in qualitative semi-structured interviews in Australia in 2014 and 2015. Data were systematically coded and thematically analysed. FINDINGS The findings demonstrate, from a managerial perspective: (1) competing demands that can hinder the prioritization of antibiotic governance; (2) ineffectiveness of audit and monitoring methods that limit rationalization for change; (3) limited clinical education and feedback to doctors; and (4) management-directed change processes are constrained by the perceived absence of a 'culture of accountability' for antimicrobial use amongst doctors. CONCLUSION Hospital managers report considerable structural and interprofessional challenges to actualizing antibiotic optimization and governance. These challenges place optimization as a lower priority vis-à-vis other issues that management are confronted with in hospital settings, and emphasize the importance of antimicrobial stewardship (AMS) programmes that engage management in understanding and addressing the barriers to change.

Abstract
OBJECTIVES Escalating antimicrobial resistance worldwide necessitates urgent optimization of antimicrobial prescribing to preserve antibiotics for future generations. Early intravenous (iv) to oral switch campaigns are one strategy that hospital-based antimicrobial stewardship programmes can incorporate to minimize inappropriate antibiotic use. Yet, iv antibiotics continue to be offered for longer than is clinically indicated, increasing hospital length of stay, increasing costs and placing patients at risk (e.g. cannula-related infections). This study aims to identify why this inappropriate prescribing trend continues. METHODS Twenty doctors (9 females and 11 males) working at a teaching hospital in north-east England participated in semi-structured interviews about their experiences of antibiotic use. NVivo10 software was used to conduct a thematic content analysis of the full interview transcripts driven by the framework approach. Results are reported according to COREQ guidelines. RESULTS Decisions around the choice of iv over oral antibiotics were influenced by three key issues: (i) consumerism, i.e. participants were concerned about the risk of litigation or complaints if patient expectations were not met; (ii) hierarchy of the medical team structure limited opportunities for de-escalation of antibiotics; and (iii) iv antibiotics were perceived as more potent and having significant mythical qualities, which participants acknowledged were not necessarily evidence based. CONCLUSIONS The iv to oral switch interventions should tailor strategies to demystify iv versus oral antibiotic efficacy, engage consumers around the negative effects of iv antibiotic overuse and examine strategies to streamline team decision-making. Addressing these issues has the potential to reduce inappropriate antibiotic use and resistance.

Barriers to uptake of antimicrobial advice in a UK hospital: a qualitative study. J Hosp Infect 2016; 93:418-22. [PMID: 27130526 DOI: 10.1016/j.jhin.2016.03.011] [Citation(s) in RCA: 57] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2015] [Accepted: 03/03/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND The role of infectious diseases (ID) and clinical microbiology (CM) in hospital settings has expanded in response to increasing antimicrobial resistance, leading to widespread development of hospital antimicrobial stewardship (AMS) programmes, the majority of which include antibiotic approval systems. However, inappropriate antibiotic use in hospitals continues, suggesting potential disjunctions between technical advice and the logics of antibiotic use within hospitals. AIM To examine the experiences of doctors in a UK hospital with respect to AMS guidance of antibiotic prescribing, and experiences of a verbal postprescription antibiotic approval process. METHODS Twenty doctors in a teaching hospital in the UK participated in semi-structured interviews about their experiences of antibiotic use and governance. NVivo10 software was used to conduct a thematic content analysis systematically. FINDINGS This study identified three key themes regarding doctors' relationships with ID/CM clinicians that shaped their antibiotic practices: (1) competing hierarchical influences limiting active consultation with ID/CM; (2) non-ID/CM consultants' sense of ownership over clinical decision-making and concerns about challenges to clinical autonomy; and (3) tensions between evidence-based practice and experiential-style learning. CONCLUSIONS This study illustrates the importance of examining relations between ID/CM and non-ID/CM clinicians in the hospital context, indicating that AMS models that focus exclusively on delivering advice rather than managing interprofessional relationships may be limited in their capacity to optimize antibiotic use. AMS and, specifically, antibiotic approval systems would likely be more effective if they incorporated time and resources for fostering and maintaining professional relationships.

A qualitative study of hospital pharmacists and antibiotic governance: negotiating interprofessional responsibilities, expertise and resource constraints. BMC Health Serv Res 2016; 16:43. [PMID: 26852016 PMCID: PMC4744423 DOI: 10.1186/s12913-016-1290-0] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2015] [Accepted: 01/29/2016] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Antibiotic treatment options for common infections are diminishing due to the proliferation of antimicrobial resistance (AMR). The impact of Antimicrobial Stewardship (AMS) programs seeking to preserve viable antibiotic drugs by governing their use in hospitals has hitherto been limited. Pharmacists have been delegated a critical role in antibiotic governance in AMS teams within hospitals but the experience of pharmacists in influencing antibiotic use has received limited attention. In this study we explore the experiences of pharmacists in antibiotic decision-making in two Australian hospitals. METHODS We conducted 19 semi-structured interviews to explore hospital-based pharmacists' perceptions and experiences of antibiotic use and governance. The analysis was conducted with NVivo10 software, utilising the framework approach. RESULTS Three major themes emerged in the pharmacist interviews including (1) the responsibilities of pharmacy in optimising antibiotic use and the interprofessional challenges therein; (2) the importance of antibiotic streamlining and the constraints placed on pharmacists in achieving this; and (3) the potential, but often under-utilised expertise, pharmacists bring to antibiotic optimisation. CONCLUSIONS Pharmacists have a critical role in AMS teams but their capacity to enact change is limited by entrenched interprofessional dynamics. Identifying how hospital pharmacy's antibiotic gatekeeping is embedded in the interprofessional nature of clinical decision-making and limited by organisational environment has important implications for the implementation of hospital policies seeking to streamline antibiotic use. Resource constraints (i.e. time limitation and task prioritisation) in particular limit the capacity of pharmacists to overcome the interprofessional barriers through development of stronger collaborative relationships. The results of this study suggest that to enact change in antibiotic use in hospitals, pharmacists must be supported in their negotiations with doctors, have increased presence on hospital wards, and must be given opportunities to pass on specialist knowledge within multidisciplinary clinical teams.

Abstract
OBJECTIVE To understand Australian hospital pharmacists' accounts of antibiotic use, and the potential role of pharmacy in antibiotic optimisation within a tertiary hospital setting. DESIGN, SETTING AND PARTICIPANTS Qualitative study, utilising semistructured interviews with 19 pharmacists in two hospitals in Queensland, Australia in 2014. Data was analysed using the framework approach and supported by NVivo10 qualitative data analysis software. RESULTS The results demonstrate that (1) pharmacists' attitudes are ambivalent towards the significance of antibiotic resistance with optimising antibiotic use perceived as low priority; (2) pharmacists' current capacity to influence antibiotic decision-making is limited by the prescribing power of doctors and the perception of antibiotic use as a medical responsibility; and, (3) interprofessional and organisational barriers exist that prevent change in the hospital setting including medical hierarchies, limited contact with senior doctors and resource constraints resulting in insufficient pharmacy staffing to foster collaborative relationships and facilitate the uptake of their advice. DISCUSSION While pharmacy is playing an increasingly important role in enhanced antibiotic governance and is a vital component of antimicrobial stewardship in Australia, role-based limitations, interprofessional dynamics and organisational/resource constraints in hospitals, if not urgently addressed, will continue to significantly limit the ability of pharmacy to influence antibiotic prescribing.

Abstract
This study aimed to document the vitamin D status of HIV-infected individuals across a wide latitude range in one country and to examine associated risk factors for low vitamin D. Using data from patients attending four HIV specialist clinics across a wide latitude range in Australia, we constructed logistic regression models to investigate risk factors associated with 25(OH)D < 75 nmol L(-1). 1788 patients were included; 87% were male, 76% Caucasian and 72% on antiretroviral therapy. The proportion with 25(OH)D < 50 nmol L(-1) was 27%, and <75 nmol L(-1) was 54%. Living in Melbourne compared with Cairns (adjusted odds ratio (aOR) 3.30; 95% CI 2.18, 4.99, P < 0.001) and non-Caucasian origin (aOR 2.82, 95% CI 2.12, 3.75, P < 0.001) was associated with an increased risk, while extreme UV index compared with low UV index was associated with a reduced risk (aOR 0.33; 95% CI 0.20, 0.55, P < 0.001) of 25(OH)D < 75 nmol L(-1). In those with biochemistry available (n = 1117), antiretroviral therapy was associated with 25(OH)D < 75 nmol L(-1); however, this association was modified by serum cholesterol status. Location and UV index were the strongest factors associated with 25(OH)D < 75 nmol L(-1). Cholesterol, the product of an alternative steroid pathway with a common precursor steroid, modified the effect of antiretroviral therapy on serum 25(OH)D.

Abstract
LighterLife Total is a very low calorie diet total dietary replacement weight reduction programme that provides Foodpacks, behavioural change therapy and group support appropriate for people with a body mass index of 30 kg m(-2) or above. A model was built to assess the cost-effectiveness of LighterLife Total, compared with (i) no treatment, Counterweight, Weight Watchers and Slimming World, as a treatment for obesity in those with a body mass index of 30 kg m(-2) or above, and (ii) no treatment, gastric banding and gastric bypass in those with a body mass index of 40 kg m(-2) or above. Change in body mass index over time was modelled, and prevalence of comorbidities (diabetes, coronary heart disease and colorectal cancer) was calculated. Costs (of intervention and treatment for comorbidities) and quality-adjusted life years were calculated. LighterLife Total was cost-effective against no treatment, Counterweight, Weight Watchers and Slimming World in the 30+ kg m(-2) group (incremental cost-effectiveness ratios: £11 895, £12 453, £12 585 and £12 233, respectively). In the 40+ kg m(-2) group, LighterLife Total was cost-effective against no treatment (incremental cost-effectiveness ratio: £4356), but less effective than gastric banding and bypass.

Abstract
BACKGROUND Effective weight loss treatment is important as obesity has severe health and socioeconomic repercussions. Emerging evidence suggests that rapid initial weight loss results in better long-term weight loss maintenance. This remains controversial and contradicts current recommendations for slower weight loss. AIM To determine the effect of a very low calorie diet (VLCD) with group-based behaviour therapy on weight loss and long-term weight management by means of a retrospective database analysis. METHODS Data for this retrospective analysis included participants who embarked on the LighterLife Total VLCD programme between 2007 and 2010, and whose weights at baseline and at least 12 months were available (n = 5965). RESULTS Data were available for 5965 individuals at 1 year, 2044 at 2 years and 580 at 3 years. At baseline, the majority of individuals were Caucasian (n = 5155), female (n = 5419), ≥ 40 years old (n = 4272), 49% were within the body mass index (BMI) range of 30-35 kg/m(2) while 51% had a BMI > 35 kg/m(2) . The average initial weight of the whole cohort was 99.1 kg (SD 16.6). Initial weight and BMI at entry onto programme, as well as numbers of weeks of weight loss were all significantly associated with weight loss achieved on the first weight loss attempt. Weight lost during the initial weight loss phase was the only factor, which was significantly associated with percentage weight loss maintenance for years 1, 2, and 3. CONCLUSION The findings of this retrospective analysis suggest that provided a longer term weight loss management programme is adhered to, large amounts of initial weight loss can result in important longer term weight loss maintenance in motivated individuals.

Long-term survival in HIV positive patients with up to 15 Years of antiretroviral therapy. PLoS One 2012; 7:e48839. [PMID: 23144991 PMCID: PMC3492258 DOI: 10.1371/journal.pone.0048839] [Citation(s) in RCA: 60] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2012] [Accepted: 10/01/2012] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Life expectancy has increased for newly diagnosed HIV patients since the inception of combination antiretroviral treatment (cART), but there remains a need to better understand the characteristics of long-term survival in HIV-positive patients. We examined long-term survival in HIV-positive patients receiving cART in the Australian HIV Observational Database (AHOD), to describe changes in mortality compared to the general population and to develop longer-term survival models. METHODS Data were examined from 2,675 HIV-positive participants in AHOD who started cART. Standardised mortality ratios (SMR) were calculated by age, sex and calendar year across prognostic characteristics using Australian Bureau of Statistics national data as reference. SMRs were examined by years of duration of cART by CD4 and similarly by viral load. Survival was analysed using Cox-proportional hazards and parametric survival models. RESULTS The overall SMR for all-cause mortality was 3.5 (95% CI: 3.0-4.0). SMRs by CD4 count were 8.6 (95% CI: 7.2-10.2) for CD4<350 cells/µl; 2.1 (95% CI: 1.5-2.9) for CD4 = 350-499 cells/µl; and 1.5 (95% CI: 1.1-2.0) for CD4≥500 cells/µl. SMRs for patients with CD4 counts <350 cells/µL were much higher than for patients with higher CD4 counts across all durations of cART. SMRs for patients with viral loads greater than 400 copies/ml were much higher across all durations of cART. Multivariate models demonstrated improved survival associated with increased recent CD4, reduced recent viral load, younger patients, absence of HBVsAg-positive ever, year of HIV diagnosis and incidence of ADI. Parametric models showed a fairly constant mortality risk by year of cART up to 15 years of treatment. CONCLUSION Observed mortality remained fairly constant by duration of cART and was modelled accurately by accepted prognostic factors. These rates did not vary much by duration of treatment. Changes in mortality with age were similar to those in the Australian general population.
