Objectives: The objective of this study was to determine the association between ertapenem and antipseudomonal carbapenem use and carbapenem resistance in Pseudomonas aeruginosa in 12 hospitals in Queensland, Australia.
Methods: Data on usage of ertapenem and other antipseudomonal carbapenems, measured in defined daily doses per 1000 occupied bed-days, were collated using statewide pharmacy dispensing and distribution software from January 2007 until June 2011. The prevalence of unique carbapenem-resistant P.
Objective: To describe monitoring of four years' isolated coronary artery bypass surgery outcomes and complications at The Prince Charles Hospital, Brisbane, Australia.
Methods: Analysis of Cardiac Surgical Register database using tabulations, funnel plots and random-effects (Bayesian shrinkage) analysis for aggregated data. Combined CUSUM and cumulative observed minus expected (modified VLAD) charts and combined CUSUM and cumulative funnel plots used for individual observation sequential data and binomial control charts and generalised additive models (GAMs) for quarterly sequential data.
Objective: To present healthcare-acquired infection surveillance data for 2001-2005 in Queensland, Australia.
Design: Observational prospective cohort study.
Setting: Twenty-three public hospitals in Queensland.
Objective: To report complication incidence to identify outliers more reliably, to provide feedback on performance, and to generate more timely alerts.
Design: Data from a retrospective entire-population study was used as an example for the charting methods.
Participants: The Western Australian (WA) Data Linkage System identified all cataract or lens-related procedures undertaken in WA and those operations complicated with endophthalmitis over 20 years from 1980.
Factors associated with health care-acquired urinary tract infection.

Background: Health care-acquired urinary tract infection is common, and the risk factors should be understood by those who manage hospitalized patients and researchers interested in interventions and programs designed to reduce rates.
Methods: We used multivariable logistic regression to identify factors that demonstrated a statistical association with infection.
Results: The incidence rate for infection was 1.
Present-day public hospitals are often lacking in humanity, costing more and doing less, and run by executive staff with minimal clinical knowledge.

Methods: Screening swabs were examined using the current laboratory protocol of direct culture on mannitol salt agar supplemented with oxacillin (MSAO-direct). The PCR method involved pre-incubation in broth for 4 hours followed by a multiplex PCR with primers directed to mecA and nuc genes of MRSA.
Background: The Melbourne Vascular Surgical Association (Melbourne, Australia) undertakes surveillance of mortality following aortic aneurysm surgery, patency at discharge following infrainguinal bypass and stroke and death following carotid endarterectomy. Quality improvement protocol employing the Deming cycle requires that the system for performing surgery first be analysed and optimized. Then process and outcome data are collected and these data require careful analysis.
