Self-reported intimate partner violence among men who have sex with men at an urban Australian sexual health clinic.

BACKGROUND: In Australia, 17% of women and 6% of men have experienced intimate partner violence (IPV). Although most IPV research has focused on heterosexual partnerships, studies suggest that men who have sex with men (MSM) may experience IPV at similar or higher rates than those documented among women. IPV may also take different forms among MSM and have different health and social impacts. This study aims to assess the utility of a screening tool for identifying and responding to IPV among MSM attending a sexual health clinic in Sydney, Australia. METHODS: Between 1 June 2020 and 30 June 2022, MSM clients were screened using standardised questions to identify IPV experienced within the preceding 12months. Answers to the screening questions were correlated with data collected routinely at the initial clinic visit, including age, employment, country of birth, drug and alcohol use, sexual partner numbers, and any history of sex work, pre-exposure prophylaxis use and HIV status, as well as any bacterial STI diagnosed at the initial visit. RESULTS: There were 2410 eligible clients and of these, 2167 (89.9%) were screened during the study period. A total of 64 men (3.0%) (95% CI 2.3-3.8%) reported experiencing physical violence or intimidation in the past 12months. Controlling for age, men who were born in Australia were 2.03 (95% CI: 1.04-3.01) times more likely to report IPV, and men who had Medicare were 2.43 (95% CI: 0.95-3.90) times more likely to report IPV than those who did not. Those who had ever injected drugs were 5.8 (95% CI: 1.87-9.73) times more likely to report IPV, and men with sexualised drug use were 4.11 (95% CI: 2.03-6.19) times more likely. Those that were employed or studying were 72% (95%CI: 0.13-0.42) less likely to report IPV. CONCLUSIONS: The prevalence of reported IPV in our study was lower than that reported by others, which may be due to differences in recruitment methods and questions asked. Associations between IPV in MSM and injecting drug use and sexualised drug use highlight that clinicians should be aware of the impact and potential for IPV particularly in those with risk factors.

Haematoma block is the most efficient technique for closed forearm fracture reduction: a retrospective cohort study.

BACKGROUND: Forearm fractures are a common ED presentation. This study aimed to compare the resource utilisation of three anaesthetic techniques used for closed forearm fracture reduction in the ED: haematoma block (HB), Bier's block (BB) and procedural sedation (PS). METHODS: A retrospective multicentre cohort study was conducted of adult patients presenting to either Port Macquarie Base Hospital ED or Kempsey District Hospital ED in New South Wales, Australia, from January 2018 to June 2021. Patients requiring a closed reduction in the ED were included. ED length of stay (LOS) was compared using a likelihood ratio test. Successful reduction on the first attempt and the number of ED specialists present for each method were both modelled with a linear regression. Staff utilisation by the level of training, cost of consumables and complications for each group were presented as descriptive statistics. RESULTS: A total of 226 forearm fractures were included. 84 used HB, 35 BB and 107 PS. The mean ED LOS was lowest for HB (187.7 min) compared with BB (227.2 min) and PS (239.3 min) (p=0.023). The number of ED specialists required for PS was higher when compared with HB and BB (p=0.001). The cost of consumables and a total number of staff were considerably lower for HB compared with PS and BB methods. PS had the highest proportion of successful reductions on the first attempt (94.4%) compared with BB (88.6%) and HB (76.2%) (p=0.006). More patients experienced complications from PS (17.8%) compared with BB (14.3%) and HB (13.1%). CONCLUSIONS: In this study, the HB method was the most efficient as it was associated with a shorter ED LOS, lower cost and staff resource utilisation. Although PS had a significantly greater proportion of successful reductions on the first attempt, HB had fewer complications than BB and PS. EDs with limited resources should consider using HB or BB as the initial technique for fracture reduction with PS used for failed HB or when regional blocks are contraindicated.

Intraoperative methadone for day-case gynaecological laparoscopy: A double-blind, randomised controlled trial.

Optimal pain relief in day-case surgery is imperative to patient comfort and timely discharge from hospital. Short-acting opioids are commonly used for analgesia in modern anaesthesia, allowing rapid recovery after surgery. Plasma concentration fluctuations from repeated dosing of short-acting opioids can cause patients to oscillate between analgesia with potential adverse effects, and inadequate analgesia requiring rescue dosing. Methadone's unique pharmacology may offer effective and sustained analgesia with less opioid consumption, potentially reducing adverse effects. Using a double-blind, randomised controlled trial, we compared post-anaesthesia care unit opioid consumption between day-case gynaecological laparoscopy patients who received either intravenous methadone (10 mg), or short-acting opioids intraoperatively. The primary outcome was post-anaesthesia care unit opioid consumption in oral morphine equivalents. Secondary outcomes included total opioid consumption, discharge opioid consumption, pain scores (0-10) until discharge, adverse effects (respiratory depression, postoperative nausea and vomiting, excess sedation), and rate of admission. Seventy patients were randomly assigned. Patients who received methadone consumed on average 9.44 mg fewer oral morphine equivalents in the post-anaesthesia care unit than the short-acting group (18.02 mg vs 27.46 mg, respectively, 95% confidence interval 0.003 to 18.88, P = 0.050) and experienced lower postoperative pain scores at every time point, although absolute differences were small. There was no evidence of lower hospital or discharge opioid consumption. No significant differences between the methadone and short-acting groups in other outcomes were identified: respiratory depression 41.2% versus 31.4%, Padjusted >0.99; postoperative nausea and vomiting 29.4% versus 42.9%, Padjusted >0.99; overnight admission 17.7% versus 11.4%, Padjusted >0.99; excess sedation 8.82% versus 8.57%, Padjusted >0.99. This study provides evidence that, although modestly, methadone can reduce post-anaesthesia care unit opioid consumption and postoperative pain scores after day-case gynaecological laparoscopy. There were no significant differences in any secondary outcomes.

Predictors of opioid use for rib fractures in a regional Australian hospital.

BACKGROUND: Rib fractures (RFs) are the leading type of single serious injury in New South Wales trauma patients. Uncontrolled pain drives the sequelae of atelectasis, pneumonia, respiratory failure, and death in severe cases. Opioids are the mainstay of management; however, they carry numerous adverse effects. Understanding patient or injury factors which predict opioid requirement is important to tailor management. Existing evidence is limited to metropolitan trauma centres (MTCs). METHODS: We conducted an observational, retrospective, single-centre cohort study of all admissions to Albury Wodonga Health diagnosed with one or more RFs and discharged between January 1st, 2017, and December 31st, 2022, inclusive. Data collected included demographics, injury characteristics, and management, including analgesia. LASSO regression was performed to determine predictors of average daily opioid use for the first five days of admission in oral morphine equivalents (mg). R2 and root mean square error (RMSE) were calculated to assess model performance. RESULTS: We included 624 patients. LASSO selected number of RFs, fracture displacement score, pulmonary contusion, new injury severity score, age, chest tube use, chronic pain history, opioid history and upper or middle lateral RF location categories as predictors. Sex, middle anterior, middle posterior, and lower RF location categories were excluded by LASSO. The out of sample R2 was 28.6 %. On the scale of log OME, the RMSE was 1.08. CONCLUSION: The model is effective at identifying predictors of opioid use in this regional centre, which are similar to those described in evidence from MTCs. However, the low R2 with wide prediction intervals limits its utility on an individual level.

Glaucoma severity at first presentation to an ophthalmologist and risk factors for late presentation in rural Australia: the S1P study.

CLINICAL RELEVANCE: Well-targeted referrals and timely commencement of treatment are essential to limiting vision loss in glaucoma. Optometrists, primary care providers, and public health policymakers can utilise predictors of late to identify and target at-risk populations. BACKGROUND: This study, which aimed to evaluate glaucoma severity at first presentation to an ophthalmologist in a rural Australian population, is the first of its kind in an Australian population. METHODS: Patient records from a large ophthalmology clinic in Port Macquarie, NSW were retrospectively reviewed using the Fight Glaucoma Blindness registry to identify patients who were first diagnosed with glaucoma at an ophthalmology practice in 2020 or 2021. Associations with glaucoma severity at presentation, measured with visual field index (VFI), were analysed using a beta-regression model. Retinal nerve fibre layer measurements were evaluated as a secondary outcome measure using linear regression. RESULTS: From 3548 new patients seen, 110 cases of glaucoma were diagnosed, 95 of whom met inclusion criteria. These comprised 41.8% primary open-angle glaucoma, 32.7% normal-tension glaucoma, 11.8% secondary open-angle glaucoma, 12.7% primary angle closure glaucoma, and 0.9% secondary angle closure glaucoma. The median VFI at presentation was 94.5%, and 71.9% of patients had a VFI ≥ 90%. However, 6.3% of patients presented with a VFI below 50%. Older age, higher intraocular pressure, and worse visual acuity were significantly associated with severity at presentation. No associations were found for remoteness, sex, family history, or glaucoma type. CONCLUSIONS: Glaucoma appears to be diagnosed relatively early in this population. Severity at presentation was associated with age, intraocular pressure, and visual acuity, but not influenced by the social determinants assessed. These findings underscore the importance of frequent comprehensive eye examinations in older patients. Replication in other Australian populations is recommended as the generalisability of these findings is limited.
