Real-time prescription monitoring: helping people at risk of harm.

Misuse of opioid analgesics and other psychoactive medicines is a serious and increasing problem in Australia. Measures are being taken to try and prevent this progressing to a public health crisis like the opioid overdose epidemic seen in the USA One measure is real-time prescription monitoring. This provides real-time information about the patient's supply of psychoactive medicines which have a high risk of being misused Having identified a patient at risk, many factors may delay appropriate management or result in the patient being discharged from care. These factors include subconscious negative stereotyping, a focus on preventing 'doctor shoppers' diverting psychoactive medicines, and a fear of sanction by regulators The Medical Board of Australia provides guidance about good practice. Patients should be treated with respect, free from bias and discrimination, and without prejudicing care because of the belief that their behaviour has contributed to their problems

Recent increase in detection of alprazolam in Victorian heroin-related deaths.

OBJECTIVES: To examine the rate of detection of alprazolam among cases of heroin-related death (HRD) in Victoria, including the relationship between alprazolam supply and HRDs. DESIGN AND SETTING: Population-based study of community alprazolam supply in Victoria and HRDs reported to the Victorian coroner from January 1990 to December 2010. MAIN OUTCOME MEASURES: Number of prescriptions for alprazolam supplied; defined daily dose (DDD) per 1000 population per 04 of alprazolam; number of cases of HRD in which alprazolam was detected through postmortem toxicological testing. RESULTS: Alprazolam supply increased by 1426%, from 0.42 DDD/1000/04 in 1990, to 6.41 in 2010. For every 1 unit increase in DDD/1000/04, the proportion of cases of HRD in which alprazolam was detected increased at an incidence rate ratio of 2.4 (95% CI, 2.1-2.8; P < 0.001). Alprazolam was detected among increasing proportions of HRDs, from 5.3% in 2005 to a peak of 35.3% in 2009. CONCLUSION: The increase in detection of alprazolam among cases of HRD, particularly since 2005, and the disproportionate increase in prescribing of the high-dose 2 mg formulation compared with other formulations suggest a need to examine alprazolam prescribing and to identify inappropriate prescribing and the circumstances of diversion from licit to illicit use.

What are the research priorities for optimising the safe and effective use of opioids in Australian general practice?

INTRODUCTION: Persistent high rates of prescription opioid use and harms remain a concern in Australia, Europe and North America. Research priority setting can inform the research agenda, strategic responses and evidence-based interventions. The objective of this study was to establish research priorities related to the safe and effective use of prescription opioids in general practice. METHODS: Consumers, clinicians and policy makers were invited to participate in a structured consensus workshop in May 2021. A modified nominal group technique was used to explore research priorities for the safe and effective use of opioids in Australian general practice. Research priorities were identified, consolidated and prioritised using a structured process. RESULTS: Seventeen consumer, medical, pharmacy, nursing, allied health and policy participants generated 26 consolidated priorities across three domains: (i) consumer-focused priorities; (ii) clinician and practice-focused priorities; and (iii) system and policy-focused priorities. The highest ranked research priorities in each of the domains were consumer characteristics that influence opioid prescribing and outcomes, opioid deprescribing strategies, and system-level barriers to prescribing alternatives to opioids, in the consumer, clinician and practice, and system and policy domains, respectively. DISCUSSION AND CONCLUSION: The priorities reflect opportunities for research priority setting within Australian general practice. The priorities provide a map for future qualitative and quantitative research that will inform safe and effective opioid prescribing.

Increasing deaths involving oxycodone, Victoria, Australia, 2000-09.

OBJECTIVE: In light of an emerging epidemic identified in the United States and Canada, to identify trends in fatal drug toxicity involving oxycodone and the demographic characteristics and indicators of socioeconomic disadvantage of the deceased. STUDY DESIGN: Population-based observational study in Victoria, Australia. POPULATION: Decedents whose death was reported to the Victorian Coroner between 2000 and 2009 and where oxycodone was detected. MAIN OUTCOME MEASURES: Association between supply of oxycodone and deaths. Demographic characteristics of decedents. Rate ratios of the rural or metropolitan location and socioeconomic indicators of disadvantage of the deceased. RESULTS: Supply to Victoria has increased nine-fold from 7.5 mg per capita in 2000 to 67.5 mg per capita in 2009. Detection of oxycodone in deaths reported to the Victorian Coroner has increased from 4 (0.08/100,000 population) in 2000 to 97 (1.78/100,000 population) in 2009-a 21-fold increase in deaths. Of the 320 cases described, 53.8% (172) were the result of drug toxicity. Of these, 52.3% were unintentional and 19.8% intentional self-harm; the remaining 27.9% are either still under investigation by the coroner or intent is unknown. Drug toxicity deaths were overrepresented in both rural areas and areas indexed with high levels of disadvantage. CONCLUSIONS: The substantial increase in the number of deaths involving oxycodone is strongly and significantly associated with the increase in supply. Most drug toxicity deaths involving oxycodone were unintentional. This newly identified trend in fatalities in Victoria supports concerns that a pattern of increasing deaths involving oxycodone is emerging globally.

Chronic pain medication management of older populations: Key points from a national conference and innovative opportunities for pharmacy practice.

OBJECTIVE: Inappropriate use of pain medication has serious consequences for older populations. Experts in the field have noted an increase in opioid prescriptions, and opioid-related hospitalisations and deaths among this vulnerable population. In the pursuit of educating pharmacists, physicians, allied healthcare professionals, researchers, academics and the public facing the challenges of chronic pain medication management, 'The Inaugural Monash University School of Public Health and Preventive Medicine (SPHPM) Best Practice in Chronic Pain Medication Management Day Conference' was held in December 2016 at the Alfred Medical Research and Education Precinct (Melbourne, Australia). METHODS: Fifteen experts presented on aspects of chronic pain epidemiology and current analgesic use in older Australians, and discussed current practice and associated challenges. RESULTS: Presenters highlighted the dramatic increase in opioid prescribing, development of tolerance and withdrawal symptoms, problems with abuse and addiction, increased risk of death from overdose or suicide, potentiation of sedative effects with concurrent use of anxiolytics/hypnotics, and medication diversion. CONCLUSIONS: Pharmacists are very accessible to patients and are crucial members of medication management teams. They have the necessary medication expertise to review medication regimens and provide patient education. Towards addressing chronic pain medication management of older populations, pharmacists can contribute in several ways, such as being aware of relevant guidelines and completing further training, contributing to policy and guideline development, participating in multidisciplinary panels, working groups and pain management teams, collaborating on research projects, and educating the community. With regards to opioid medication management, pharmacists are in an ideal position to: monitor prescription dispensing and potential misuse, provide education about overuse, and, if appropriate, provide access to naloxone. In order to fulfil these roles and responsibilities, allied healthcare professionals should be educated and informed, and opportunities for continuing professional education should be available and utilised. Pharmacists should have the necessary knowledge and skills to optimise chronic pain management, and to both deliver and inform policies and guidelines on pharmacological management of chronic pain in older people.

Unintentional mortality associated with paracetamol and codeine preparations, with and without doxylamine, in Australia.

INTRODUCTION: Misuse of paracetamol, codeine and doxylamine combination analgesics may lead to addiction and mortality. This study aimed to (1) identify unintentional deaths in Australia associated with use of combination analgesic products containing paracetamol, codeine and doxylamine; (2) describe cases characteristics, including demographics and additional medication use; and (3) identify common factors associated with misuse and mortality of these medicines in Australia. DESIGN: This retrospective case series analysed National Coronial Information System data to identify cases of unintentional death attributable to paracetamol, codeine and doxylamine products between 2002 and 2012. SETTING: Three Eastern Australian states: New South Wales, Queensland, Victoria, comprising a population of approximately 18.6 million people. RESULTS: 441 unintentional deaths attributed to paracetamol/codeine products were identified; doxylamine was detected in 102 cases (23%). Overall unintentional death rates rose from 0.9-per-million in 2002 to 3.6-per-million in 2009, declining to 1.9-per-million in 2012. Median age at time of death was 48, half of all cases occurred between 35-54 years of age, and 57% were female. Concomitant medication use was detected in 79% of cases, including benzodiazepines, other opioids, psychiatric medications, alcohol and illicit drugs. Behaviours consistent with drug misuse including doctor/pharmacy shopping, excessive dosages and extended use, were identified in 24% of cases. CONCLUSIONS: This study identified 441 deaths associated with codeine-combination analgesic products across three Australian states; with an average of 40 deaths per year. Death commonly involved multiple substance use and abuse behaviours indicative of misuse and dependence.

Buprenorphine diversion and injection in Melbourne, Australia: an emerging issue?

AIMS: To examine indicators of buprenorphine diversion and injection among injecting drug users in Melbourne, Australia and to determine the factors associated with buprenorphine injection. DESIGN: Melbourne arm of the 2002 Illicit Drug Reporting System (IDRS) cross-sectional study. SETTING: Five Needle and Syringe Programme sites in Melbourne, Australia. PARTICIPANTS: A total of 156 current injecting drug users (IDU). Study eligibility criteria were at least monthly injection during the previous 6 months, and Melbourne residence for at least the preceding 12 months. MEASUREMENTS: Structured questionnaire covering demographic characteristics, drug use history, the price, purity and availability of drugs, criminal activity, risk-taking behaviours, health-related issues and general drug use trends. FINDINGS: Over one-third (37%) of the study sample reported injecting buprenorphine in their life-time and 33% reported injecting the drug in the last 6 months. Recent buprenorphine injection was associated with the injection of other drug types (i.e. polydrug injectors), opioid substitution treatment, injection-related health problems and involvement in crime. Almost half (47%) of those who reported recent buprenorphine injection reported obtaining the drug illicitly at least once during that time. CONCLUSIONS: Given the significant health harms associated with intravenous buprenorphine use (e.g. vein damage, abscesses and infections, precipitated withdrawal, blood-borne virus transmission, hospitalization and death), routine monitoring of the misuse of buprenorphine in Melbourne is warranted. These results suggest the need for development of effective countermeasures to address diversion and injection of buprenorphine in this setting.

Association of benzodiazepine injection with the prescription of temazepam capsules.

Temazepam capsules have become a popular choice for benzodiazepine injection by injecting drug users, and serious vascular and tissue damage leading to ulcers and gangrene can result. We compared the self-reported benzodiazepine injecting behaviour of 91 heroin users with their Pharmaceutical Benefits Schedule (PBS) records for the preceding 5 years. We found that individuals prescribed PBS temazepam capsules were more likely to report injecting benzodiazepines than individuals who had either not been prescribed PBS temazepam capsules or had been prescribed PBS temazepam tablets. These results provide empirical support for the argument to limit the prescription and supply of temazepam capsules in Australia.

Regulatory responses to over-the-counter codeine analgesic misuse in Australia, New Zealand and the United Kingdom.

OBJECTIVE: Analysis of the policy response by Australia's National Drugs and Poisons Schedule Committee (NDPSC) and comparison with recommendations by expert advisory committees in New Zealand and the United Kingdom. METHODS: Analysis of public policy documents of relevant regulatory authorities was conducted. Data were extracted regarding changes to over-the-counter (OTC) codeine analgesic scheduling, indications, maximum unit dose, maximum daily dose, maximum pack size, warning labels, consumer medicine information and advertising. Where available, public submissions and other issues considered by the committees and rationale for their recommendations were recorded and thematically analysed. RESULTS: Expert advisory committees in Australia, NZ and the UK defined the policy problem of OTC codeine misuse and harm as small relative to total use and responded by restricting availability. Pharmacist supervision was required at the point-of-sale and pack sizes were reduced to short-term use. CONCLUSIONS: Comparison with recommendations by expert advisory committees in NZ and the UK suggests the NDPSC's actions in response to OTC codeine misuse were appropriate given the available evidence of misuse and harm, but highlights opportunities to utilise additional regulatory levers. IMPLICATIONS: Framing policy problems as matters of public health in the context of limited evidence may support decision makers to implement cautionary incremental policy change.

Beyond the paper trail: using technology to reduce escalating harms from opioid prescribing in Australia.

OBJECTIVE: The paper highlights the extent of pharmaceutical drug misuse problems in Australia and explores how pharmaceutical opioid misuse could be reduced by implementation of a technological tool: a prescription co-ordination program (PCP). The paper explores how enhancements to existing computer-assisted clinical decision support systems through real-time, on-line information to prescribers, pharmacists and regulators could address drug-seeking and improve the quality use of medicines. APPROACH: Trends in national and international prescription opioid use and related harms are examined with attention directed to drug-seeking behaviour and intentional misuse. The international literature concerning PCPs is reviewed and implications for technological advances in Australia are outlined. CONCLUSION: Australia has a burgeoning problem associated with the misuse of pharmaceutical opioids. There is increased recognition of a range of iatrogenic harms. A number of factors limit Australia's response capacity including lack of technological capacity to provide on-line, real-time information for prescribers and pharmacists. IMPLICATIONS: Providing prescribers, pharmacists and regulators with on-line, real-time information about patients' prescription opioid use will improve the quality use of medicines. A national system is required to co-ordinate data on Pharmaceutical Benefits Scheme, Repatriation Pharmaceutical Benefits Scheme and unsubsidised medicines, including private prescriptions. Pharmaceutical opioids are not the only medicines subject to misuse and therefore the need to capture data on other relevant medicines is also addressed.

Increasing the benefits and reducing the harms of prescription opioid analgesics.

ISSUES: Consumption of prescription opioid analgesics (POAs) in Australia has increased steadily in recent years, raising concerns of increasing harms including overdose and dependence, as has occurred in the USA. APPROACH: Exposition of the Royal Australasian College of Physicians Prescription Opioid Policy with reference to the published literature, drawing out principles for harm reduction for psychoactive pharmaceutical drugs. KEY FINDINGS: Complex professional, patient, regulatory and market factors influence health professionals balancing the benefits and harms of POAs. Owing to the potential for diversion, overlapping markets probably exist for pharmaceutical opioids used for populations with cancer pain, chronic non-cancer pain, and people dependent on pharmaceutical and illicit opioids (including those needing opioid substitution treatment). Attempts to reduce or restrict supply in one area may increase demand in others. There is a need to consider new harm reduction strategies for people with problematic pharmaceutical opioid use. These people are demographically not well characterised, and may be distinct from the more familiar population of injection drug users. IMPLICATIONS: Harm reduction is a valid approach for POAs. However, the role of health professionals as gatekeepers of opioid supply, the need to optimise health benefits of POAs, and the likely interplay of complex market forces among populations consuming opioids have no close parallel in harm reduction for other substances. This poses fundamentally different challenges. CONCLUSIONS: Reducing inappropriate supply and demand for POAs while maximising their benefits and minimising their harms may improve health outcomes.

Over-the-counter codeine analgesic misuse and harm: characteristics of cases in Australia and New Zealand.

AIM: To describe the characteristics of clients addicted to over-the-counter (OTC) codeine analgesics presenting to an Auckland open-access clinic, and to compare them to clients admitted to a New Zealand detoxification unit, and in the Australian community. METHOD: Cross-sectional study of clients presenting to a regional, open-access detoxification clinic covering the Greater Auckland area between 1 January and 31 March 2010. RESULTS: Fifteen clients were analysed, and compared to 77 similar clients identified in Victoria and five other Australian States, and 7 clients admitted to a New Zealand detoxification unit. Cases in each cohort were consistent with those in the published literature, and appear to be similar to each other both demographically and in terms of the high average tablets consumption (49-65 tablets per day), the serious non-steroidal anti-inflammatory drug (NSAID) adverse drug reactions identified, and the long duration of misuse. Many had a history of alcohol or other drug use and mental health disorder. CONCLUSIONS: This study has identified that controls on OTC codeine analgesics in both countries were not sufficient to limit non-medical use of these products. As a result, cases identified in these two countries escalated the number of self-administered tablets taken daily for misuse, resulting in codeine dependence and serious NSAID toxicity secondary to this dependence.

Serious morbidity associated with misuse of over-the-counter codeine-ibuprofen analgesics: a series of 27 cases.

OBJECTIVE: To investigate morbidity related to misuse of over-the-counter (OTC) codeine-ibuprofen analgesics. DESIGN AND SETTING: Prospective case series collected from Victorian hospital-based addiction medicine specialists between May 2005 and December 2008. MAIN OUTCOME MEASURES: Morbidity associated with codeine-ibuprofen misuse. RESULTS: Twenty-seven patients with serious morbidity were included, mainly with gastrointestinal haemorrhage and opioid dependence. The patients were taking mean daily doses of 435-602 mg of codeine phosphate and 6800-9400 mg ibuprofen. Most patients had no previous history of substance use disorder. The main treatment was opioid substitution treatment with buprenorphine-naloxone or methadone. CONCLUSIONS: Although codeine can be considered a relatively weak opioid analgesic, it is nevertheless addictive, and the significant morbidity and specific patient characteristics associated with overuse of codeine-ibuprofen analgesics support further awareness, investigation and monitoring of OTC codeine-ibuprofen analgesic use.
