Multicenter Study Observational StudyPrevalence and predictors of opioid use before orthopaedic surgery in an Australian setting: A multicentre, cross-sectional, observational study.
Opioid analgesics are commonly used by patients awaiting orthopaedic surgery, and preoperative opioid use is associated with a greater burden of postoperative pain, suboptimal surgical outcomes and higher healthcare costs. This study aimed to examine the prevalence of total opioid use before elective orthopaedic surgery with a focus on regional and rural hospitals in New South Wales, Australia. This was a cross-sectional, observational study of patients undergoing orthopaedic surgery conducted between April 2017 and November 2019 across five hospitals that included a mix of metropolitan, regional, rural, private and public settings. ⋯ Rates of preoperative opioid use ranged from 20.6% (13/63) at a metropolitan hospital to 48.8% (21/43) at an inner regional hospital. Multivariable logistic regression showed that the inner regional setting was a significant predictor of opioid use before orthopaedic surgery (adjusted odds ratio 2.6; 95% confidence interval 1.0 to 6.7) after adjusting for covariates. Opioid use prior to orthopaedic surgery is common and appears to vary by geographical location.

Multicenter Study Observational StudyPrevalence and predictors of long-term opioid use following orthopaedic surgery in an Australian setting: A multicentre, prospective cohort study.
Opioid analgesics prescribed for the management of acute pain following orthopaedic surgery may lead to unintended long-term opioid use and associated patient harms. This study aimed to examine the prevalence of opioid use at 90 days after elective orthopaedic surgery across major city, regional and rural locations in New South Wales, Australia. We conducted a prospective, observational cohort study of patients undergoing elective orthopaedic surgery at five hospitals from major city, regional, rural, public and private settings between April 2017 and February 2020. ⋯ Opioid use at 90 or more days after orthopaedic surgery was reported by 15.8% (57/361; 95% confidence interval (CI) 12.2-20%) of all participants and ranged from 3.5% (2/57) at a major city location to 37.8% (14/37) at an inner regional location. Predictors of long-term postoperative opioid use in the multivariable analysis were surgery performed at an inner regional location (adjusted odds ratio 12.26; 95% CI 2.2-68.24) and outer regional location (adjusted odds ratio 5.46; 95% CI 1.09-27.50) after adjusting for known covariates. Long-term opioid use was reported in over 15% of patients following orthopaedic surgery and appears to be more prevalent in regional locations in Australia.

Supply of opioids and information provided to patients after surgery in an Australian hospital: A cross-sectional study.
Opioids are commonly prescribed to manage pain after surgery. However, excessive supply on discharge can increase patients' risk of persistent opioid use and contribute to the reservoir of unused opioids in the community that may be misused. This study aimed to evaluate the use of opioids in Australian surgical patients after discharge and patient satisfaction with the provision of opioid information after discharge. ⋯ However, the majority (51.5%; 34/66) did not recall receiving any information about the signs of opioid toxicity and interactions between opioids and alcohol. In conclusion, around 40% of patients had more than half of their opioid supply remaining after they ceased taking their opioid. Although most patients recalled receiving information about their opioids, more than half did not recall receiving any information about the signs of opioid toxicity or interactions between opioids and alcohol.

Perioperative pain management in thoracic surgery: A survey of practices in Australia and New Zealand.
There are few data on current trends in pain management for thoracic surgery in Australia and New Zealand. Several new regional analgesia techniques have been introduced for these operations in the past few years. Our survey aimed to assess current practice and perceptions towards various modalities of pain management for thoracic surgery among anaesthetists in Australia and New Zealand. ⋯ If representative of anaesthetists in Australia and New Zealand more widely, this trend may result in less exposure of junior anaesthetists to the insertion and management of thoracic epidurals, potentially resulting in reduced familiarity and confidence in the technique. Furthermore, it demonstrates a notable reliance on surgically or intraoperatively placed paravertebral catheters as the primary analgesic modality, and suggests the need for future studies assessing the optimal method of catheter insertion and perioperative management. It also gives some insight into the current opinion and practice of the respondents with regard to formalised enhanced recovery after surgery pathways, acute pain services, opioid-free anaesthesia, and current medication selection.
