To identify characteristics associated with the hospitalisation and death of people with COVID-19 living in residential aged care facilities (RACFs).Retrospective cohort study.All confirmed (polymerase chain reaction testing) or probable SARS-CoV-2 infections (rapid antigen tests) in residents of the 86 RACFs in the Metro South Hospital and Health Service area (southeast Queensland), 13 December 2021 - 24 January 2022.Hospitalisation within 14 days or death within 28 days of COVID-19 diagnosis.Of 1071 RACF residents with COVID-19, 151 were hospitalised within 14 days and 126 died within 28 days of diagnosis. Likelihood of death increased with age (per five years: adjusted odds ratio [aOR], 1.38; 95% confidence interval [CI], 1.21-1.57), but not that of hospitalisation. Men were more likely to be hospitalised (aOR, 1.7; 95% CI, 1.2-2.4) or die (aOR, 2.5; 95% CI, 1.7-3.6) than women. The likelihood of hospitalisation was greater for those with dementia (aOR, 1.9; 95% CI, 1.2-3.0), heart failure (aOR, 1.7; 95% CI, 1.1-2.7), chronic kidney disease (aOR, 1.7; 95% CI, 1.1-2.5), or asthma (aOR, 2.2; 95% CI, 1.2-3.8). The likelihood of death was greater for residents with dementia (aOR, 2.2; 95% CI, 1.3-3.7), diabetes mellitus (aOR, 1.9; 95% CI, 1.3-3.0), heart failure (aOR, 2.0; 95% CI, 1.1-3.3), or chronic lung disease (aOR, 1.7; 95% CI, 1.1-2.7). The likelihood of hospitalisation and death were each higher for residents who had received two or fewer vaccine doses than for those who had received three doses.Most characteristics that influenced the likelihood of hospitalisation or death of RACF residents with COVID-19 were non-modifiable factors linked with frailty and general health status. Having received three COVID-19 vaccine doses was associated with much lower likelihood of hospitalisation or death.

The aim of this study was to quantify culturable microorganisms on needleless connectors (NCs) attached to peripheral intravenous catheters in hospitalized adult medical patients. Half (50%) of 40 NCs were contaminated with microorganisms commonly found on the skin or mouth. Staphylococcus capitis and Staphylococcus epidermidis were most commonly isolated. Emergency department insertion and higher patient dependency were statistically associated with positive NC microorganism growth. These results reaffirm the need for NC decontamination prior to access.

To the Editor: Since the introduction in the early 1990s of a needleless connector (NC) on vascular access devices to minimize the risk of needle stick injuries to healthcare workers, their use is now well established. Unfortunately, intermittent reports from facilities have shown an increase in bloodstream infections (BSIs) thought to be associated with NC use.

It is well accepted that good hand hygiene practice is important in reducing health care–associated infection and therefore saving lives.Despite the intense research effort that has been undertaken over decades, a level of hand hygiene compliance that results in reduction in health care–associated infection has never been established.The World Health Organization program, My 5 Moments for Hand Hygiene, has resulted in an internationally accepted manner of observation and reporting of hand hygiene compliance.

Background Needlestick injury (NSI) with hollow-bore needles remains a significant risk of bloodborne virus acquisition in health care workers. The impact on NSI rates after substantial replacement of conventional hollow-bore needles with the simultaneous introduction of safety-engineered devices (SEDs) including retractable syringes, needle-free intravenous (IV) systems, and safety winged butterfly needles was examined in an 800-bed Australian university hospital. Methods NSIs were prospectively monitored for 2 years (2005-2006) after the introduction of SEDs and compared with prospectively collected preintervention NSI data (2000-2004). Results Preintervention hollow-bore NSI rates over 10 years persisted at a constant rate between 3.01 and 3.77 per 100 full-time equivalent employees (FTE) ( P = .31). Rates for 2005 (1.93; 95% CI: 1.48-2.47 per 100 FTE) and 2006 (1.50; 95% CI: 1.11-1.97 per 100 FTE) were significantly lower than the average rate for the preintervention years (3.39; 95% CI: 2.7-4.24 per 100 FTE, P = .00004). This represents a fall of 49% (43.1%-55.7%) in hollow-bore NSI, contributed to by the virtual elimination of NSI related to accessing IV lines. More importantly, high-risk injuries were also reduced 57% by retractable syringe use with an overall budgetary increase of approximately US $90,000 per annum. Conclusion Introduction of SEDs results in an impressive fall in NSI with minimal cost outlay.

We evaluated three markers of ethanol intake [whole blood associated acetaldehyde (WBAA), serum beta-hexosaminidase, and gamma-glutamyl transpeptidase (GGT)] in four groups of subjects: teetotalers (n = 104), random insurance applicants or "normals" (n = 1,010), subjects enrolling in an alcohol treatment program or "alcoholics" (n = 31), and subjects attending outpatient drug/alcohol treatment follow-up clinics (n = 128). Significant differences (p < 0.004 for each assay and each comparison) were found in the mean values between teetotalers and normals and normals and alcoholics. Male teetotalers and normals had significantly (p < 0.002) higher levels of WBAA than females of the same group. Male normals had significantly higher levels of GGT than females (p < 0.001). GGT increased with age in the normal population into the fifth decade and decreased thereafter. WBAA was the most sensitive assay with 97% of alcoholics having values above the 99th percentile for the teetotaler population (vs. 66% for serum beta-hexosaminidase and 70% for GGT). None of the alcoholic subjects had values for all three assays below the 99th percentile for teetotalers compared with 21% of those in follow-up and 72% of normals. We conclude that WBAA appears to be the best of the three markers studied and that measurement of multiple markers for ethanol use appears clinically useful and incremental.
