Objective: To assess the efficacy of a multimodal, centrally coordinated, multisite hand hygiene culture‐change program (HHCCP) for reducing rates of methicillin‐resistant Staphylococcus aureus (MRSA) bacteraemia and disease in Victorian hospitals. Design, participants and setting: A pilot HHCCP was conducted over a 24‐month period (October 2004 to September 2006) in six Victorian health care institutions (4 urban, 2 rural; total beds, 2379). Subsequently, we assessed the efficacy of an identical program implemented throughout Victorian public hospitals over a 12‐month period (beginning between March 2006 and July 2006). Main outcome measures: Rates of hand hygiene (HH) compliance; rates of MRSA disease (patients with bacteraemia and number of clinical isolates per 100 patient discharges [PD]). Results: Mean HH compliance improved significantly at all pilot program sites, from 21% (95% CI, 20%–22%) at baseline to 48% (95% CI, 47%–49%) at 12 months and 47% (95% CI, 46%–48%; range, 31%–75%) at 24 months. Mean baseline rates for the number of patients with MRSA bacteraemia and the number of clinical MRSA isolates were 0.05/100 PD per month (range, 0.00–0.13) and 1.39/100 PD per month (range, 0.16–2.39), respectively. These were significantly reduced after 24 months to 0.02/100 PD per month for bacteraemia (P = 0.035 for trend; 65 fewer patients with bacteraemia) and 0.73/100 PD per month for MRSA isolates (P = 0.003; 716 fewer isolates). Similar findings were noted 12 months after the statewide roll‐out, with an increase in mean HH compliance (from 20% to 53%; P < 0.001) and reductions in the rates of MRSA isolates (P = 0.043) and bacteraemias (P = 0.09). Conclusions: Pilot and subsequent statewide implementation of a multimodal HHCCP was effective in significantly improving HH compliance and reducing rates of MRSA infection.

Objectives: To report the quarterly incidence of hospital‐identified Clostridium difficile infection (HI‐CDI) in Australia, and to estimate the burden ascribed to hospital‐associated (HA) and community‐associated (CA) infections. Design, setting and patients: Prospective surveillance of all cases of CDI diagnosed in hospital patients from 1 January 2011 to 31 December 2012 in 450 public hospitals in all Australian states and the Australian Capital Territory. All patients admitted to inpatient wards or units in acute public hospitals, including psychiatry, rehabilitation and aged care, were included, as well as those attending emergency departments and outpatient clinics. Main outcome measures: Incidence of HI‐CDI (primary outcome); proportion and incidence of HA‐CDI and CA‐CDI (secondary outcomes). Results: The annual incidence of HI‐CDI increased from 3.25/10 000 patient‐days (PD) in 2011 to 4.03/10 000 PD in 2012. Poisson regression modelling demonstrated a 29% increase (95% CI, 25% to 34%) per quarter between April and December 2011, with a peak of 4.49/10 000 PD in the October–December quarter. The incidence plateaued in January–March 2012 and then declined by 8% (95% CI, − 11% to − 5%) per quarter to 3.76/10 000 PD in July–September 2012, after which the rate rose again by 11% (95% CI, 4% to 19%) per quarter to 4.09/10 000 PD in October–December 2012. Trends were similar for HA‐CDI and CA‐CDI. A subgroup analysis determined that 26% of cases were CA‐CDI. Conclusions: A significant increase in both HA‐CDI and CA‐CDI identified through hospital surveillance occurred in Australia during 2011–2012. Studies are required to further characterise the epidemiology of CDI in Australia.

A 'decision ecology' model that acknowledges the wider social context, individual narratives and emphasises trust between professionals and patients may support decision-making at end of life. Such a model must support autonomy not just at the level of wider decisions around care choice but also at the level of everyday care.

BackgroundIn recent year, national bodies have been actively addressing the increasing concern on the spread of healthcare-associated infections (HAIs). The current study measures the knowledge, intentions and beliefs of third-year Australian nursing students on key infection prevention and control (IPC) concepts.MethodsA cross-sectional study of final-year undergraduate nursing students from Schools of Nursing at six Australian universities was undertaken. Students were asked to participate in an anonymous survey. The survey explored knowledge of standard precautions and transmission based precautions. In addition intentions and beliefs towards IPC were explored.Results349 students from six universities completed the study. 59.8% (95% CI 58.8–60.8%) of questions were answered correctly. Significantly more standard precaution questions were correctly answered than transmission-based precaution questions (p < 0.001). No association was found between self-reported compliance with IPC activities and gender or age. Certain infection control issues were correlated with the percentage of correctly answered transmission-based precaution questions. The participants were most likely to seek infection control information from an infection control professional.ConclusionKnowledge on transmission-based precautions was substandard. As transmission-based precautions are the foundation of IPC for serious organisms and infections, education institutions should reflect on the content and style of educational delivery on this topic.Electronic supplementary materialThe online version of this article (doi:10.1186/s12912-014-0043-9) contains supplementary material, which is available to authorized users.
