Abstract
The solid product of wastewater treatment plants is commonly used as a fertiliser to increase sustainability and waste reuse. It has undergone extensive treatment to remove high nutrient loads, pathogens and heavy metals but the extensive matrix of household chemicals, pesticides and pharmaceuticals remains, untargeted by most treatment technologies. These compounds, particularly pharmaceuticals, have been detected in biosolids with there being evidence of uptake by plants. With the current opioid pandemic in North America and overprescription, a simple method is required for the extraction of opioids from a solid medium as to ascertain the concentrations the environment is exposed to. A sonication-liquid-liquid extracted method was developed where biosolids were suspended in water and extracted using ethyl acetate before analysis on LC MS/MS. Sodium and potassium chloride were compared along with acidic and alkaline conditions. The optimised method utilised NaCl at a pH of 12 and was validated for 17 opioids, achieving linearity >0.987, 86-113% matrix effect and 0.1-10 μg/kg limits of detection. Upon analysis of biosolids destined for agriculture, 14 opioids were detected across all samples in a concentration range of 1-289 μg/kg.

Restriction of oxycodone in the emergency department (ROXY-ED): A randomised controlled trial. Br J Pain 2023; 17:491-500.

Abstract
Background The prescription of opioids in emergency care has been associated with harm, including overdose and dependence. The aim of this trial was to assess restriction of access to oxycodone (ROXY), in combination with education and guideline modifications, versus education and guideline modifications alone (standard care) to reduce oxycodone administration in the Emergency Department (ED). Methods An unblinded, active control, randomised controlled trial was conducted in an adult tertiary ED. Participants were patients aged 18-75 years who had analgesics administered in the ED. The primary intervention was ROXY, through removal of all oxycodone immediate release tablets from the ED imprest, with availability of a small supply after senior clinician approval. The intervention did not restrict prescription of discharge medications. The primary outcome measure was oxycodone administration rates. Secondary outcomes were administration rates of other analgesic medications, time to initial analgesics and oxycodone prescription on discharge. Results There were 2258 patients eligible for analysis. Oxycodone was administered to 80 (6.1%) patients in the ROXY group and 221 (23.3%) patients in the standard care group (relative risk (RR) 0.26; 95% CI: 0.21 to 0.33; p < .001). Tapentadol was prescribed more frequently in the ROXY group (RR 2.17; 95% CI: 1.71-2.74), while there were no differences in prescription of other analgesic medications. On discharge, significantly fewer patients were prescribed oxycodone (RR 0.51; 95% CI: 0.39-0.66) and no differences were observed in prescription rates of other analgesic medications. There was no difference in time to first analgesic (HR 0.94; 95% CI: 0.86-1.02). Conclusions Restricted access to oxycodone was superior to education and guideline modifications alone for reducing oxycodone use in the ED and reducing discharge prescriptions of oxycodone from the ED. The addition of simple restrictive interventions is recommended to enable rapid changes to clinician behaviour to reduce the potential harm associated with the prescribing of oxycodone in the ED.

Abstract
Introduction Patients with chronic pain (CP) are frequent users of general practitioners (GPs). Aim This study aimed to assess factors associated with the rate of GP visits related to pain in patients with CP. Methods This study used data collected by adult specialist pain management services (SPMS) that participated in the electronic Persistent Pain Outcomes Collaboration (ePPOC) in Australia. Adult patients (18 years or older) with CP (duration greater than 3 months) who were referred to SPMS from the calendar year 2015-2021 were included (N = 84 829). Results Patients who reported severe anxiety, stress, pain, pain interference, pain catastrophising and severely impaired pain self-efficacy were more likely to seek help from a GP. Patients with longer pain duration had a lower rate of GP visits. The rate of GP visits was 1.22 (IRR = 1.22, 95% CI: 1.19, 1.26) times higher in patients with severe pain severity, compared to patients with mild pain severity. Patients who used opioids were more likely to visit a GP (IRR = 1.32, 95% CI: 1.30, 1.34) than those who were not using opioids. Discussions More than half of the adult CP patients had greater than three GP visits in the 3 months before referral. This study would indicate that some patients may attend their GP to seek an opioid prescription. Given the rising use of opioids nationally, future study is required on opioid users' GP visitation practices. Additionally, the inverse association between pain duration and the rate of GP visits warrants further exploration.
