Abstract
OBJECTIVES To describe and map what is known about unconventional uses of paracetamol through a scoping review of published literature by adopting adopted a PRISMA systematic approach methodology. KEY FINDINGS Four themes for unconventional uses of paracetamol emerged: (a) use of paracetamol in sleep (a-1) positive effect of paracetamol on sleep (n = 9) or (a-2) neutral or negative effect of paracetamol on sleep (n = 9); (b) use of paracetamol in sport (n = 13); (c) mixing paracetamol with drinks, waterpipe and illicit drugs (n = 5); and (d) miscellaneous uses (n = 4). Forty records were reviewed and charted. Available literature supports concern around the potential of harmful or non-medical use of paracetamol, especially among patients with a history of substance use, parents of young children or athletes. SUMMARY Paracetamol (acetaminophen) is one of the most popular and widely used drugs for the treatment of pain and fever. It is considered remarkably safe if used within instructions. However, there is growing evidence that paracetamol, is sometimes used outside approved indications or abused (i.e. used for non-medical reasons). This review highlights the need for enhanced pharmacovigilance and surveillance of non-medical paracetamol use and raising general public awareness of its potential dangers especially in higher than recommended doses.

Abstract
BACKGROUND AND AIM Paracetamol is the most frequently used analgesic in Australia and can be purchased without a prescription. We aimed to investigate the epidemiology and outcome of paracetamol overdoses occurring in Victoria, Australia. METHODS The Victorian admitted episode dataset was examined for all patients who had a diagnosis of paracetamol poisoning (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification [ICD-10-AM]: T39.1) or paracetamol adverse effect in therapeutic use (Y45.5) from July 1, 2000 to June 30, 2007. Data extracted included all ICD-10 codes related to their admissions, gender, age range, date of admission, and cause of death (if applicable). RESULTS Over 7 years, there was a total of 14,662 hospital admissions for paracetamol overdose with a mean of 2095 cases per year. Accidental overdoses comprised 15% (n = 2149) of cases. The overdose rate fell from 46 cases per 100,000 in 2001 to 39 cases per 100,000 in 2006 (P < 0.001). Most overdoses occurred in women (71%), and patients between 15 and 50 years old comprised 78% of all cases. Complications and mortality were relatively uncommon, with only 26 deaths directly attributable to paracetamol overdose over the 7 years. No child under 15 years old died from their overdose. CONCLUSION Admission to Victorian hospitals with paracetamol overdose presents an enormous and in many cases preventable health-care burden. Fortunately, there has been a gradual fall in admissions, and most cases appear relatively benign. Further reductions in overdose could be achieved with increased awareness by physicians and the general public regarding the potential for accidental overdose, and increasing funding for mental health initiatives.

Abstract
BACKGROUND To examine (a) numbers of alcohol and drug-related hospital separations, 1999-2005; (b) demographics of these separations; (c) principal diagnoses co-occurring with drug-related problems; (d) length of hospital stay. METHODS Data from the National Hospital Morbidity Database (NHMD) were analysed. Hospital separations where alcohol, opioids, amphetamine, cannabis, cocaine, other drugs (such as sedatives and hypnotics) and pharmaceutical poisoning were mentioned were examined. RESULTS Numbers per million persons were highest for alcohol, followed by other drugs, particularly sedatives and hypnotics. Alcohol and opioid-related problems were prominent among older age groups, whereas cannabis and pharmaceutical poisoning problems had greater proportions among 15-24 year olds. Opioid-related separations were relatively high in number within the context of prevalence of use, and often accompanied by principal diagnoses of physical or general health problems. Almost half of amphetamine and cannabis-related separations were accompanied by principal diagnoses of mental health problems. CONCLUSIONS This research highlights the complexities of drug-related hospital presentations, indicating the need for thorough assessment of physical and mental problems, as well as a drug use history at the time of admission. Continued development of integrated models of care, targeting both mental health and drug use are essential. Consistent with the international literature, many of these separations are preventable, particularly those for pharmaceutical poisoning. Finally, ongoing efforts to reduce the significantly greater harms related to opioid use, as well as increasing treatment opportunities for opioid-dependent people in Australia is an important public health priority.

Abstract
AIMS To describe how changes in legislation to restrict paracetamol sales have affected overdose discharges and death associated with the drug in Scotland. METHODS A descriptive analysis of routine death and hospital discharge data for the entire Scottish population between 1995 and 2004. Patients in Scotland participated who were discharged from hospital with a diagnosis of poisoning; deaths in Scotland from diagnosis of poisoning 1995-2003 were also analysed. Outcome measures were changes in mortality and overdose due to poisoning involving paracetamol. A comparison was made of in-hospital and out-of-hospital mortality in fatalities involving paracetamol. RESULTS The majority of paracetamol-associated deaths were due to co-proxamol. Deaths associated with paracetamol alone or with ethanol occurred principally in hospital and were a minority of deaths overall. The proportion of in-hospital deaths attributed to paracetamol increased (post/pre ratio 1.347; 95% confidence interval 1.076, 1.639; P = 0.013). Overall numbers of cases discharged with poisoning fell. The proportion of these involving paracetamol in any form increased significantly in all groups except young men aged 10 to <20 years. CONCLUSIONS Legislation has not reduced mortality or proportional use of paracetamol in overdose, both of which appear to have increased in Scotland since pack-size limitations. Other approaches are necessary to reduce the death rate from overdoses involving paracetamol.

Abstract
In September 1999, several Canadian provinces had place-of-sale restrictions lifted that had limited the sale of acetaminophen >325 mg and packages >24 tablets (any strength) to pharmacies only. This allowed the sale of all strengths of immediate-release acetaminophen in all package sizes in nonpharmacy locations. This study's purpose was to explore the effect that lifting restrictions on acetaminophen place of sale may have had on reported hospitalizations in Canada related to acetaminophen overdose toxicity. Using hospital discharge data, provinces with no preexisting restrictions on place of sale were compared with those in which restrictions were lifted in September 1999. Cases of reported APAP overdose included ICD-9/9-CM code 965.4, ICD-9 code E850.2, or ICD-9-CM code E850.4. Cases with reported acute liver toxicity included ICD-9/9-CM codes 570, 572.2, 572.4, V42.7, or procedure code 50.5. There were no significant differences between the 1.5-year periods pre- and post-September 1999 in annual incidence rates per 100,000 persons ages >/=12 years of hospitalizations reported with acetaminophen overdose, either overall or limited to those with death as an outcome, or in hospitalization reports with both acetaminophen overdose and acute liver toxicity, either overall (provinces with no restrictions: pre = 0.70, post = 0.80, P = 0.6328; provinces with restrictions lifted in September 1999: pre = 0.49, post = 0.47, P = 0.8649) or limited to those with death as an outcome (provinces with no restrictions: pre = 0.22, post = 0.12, P = 0.3030; provinces with restrictions lifted in September 1999: pre = 0.13, post = 0.09, P = 0.3589). In conclusion, the decision to lift Canadian place-of-sale restrictions increased acetaminophen availability and did not increase the rate of reported hospitalizations related to acetaminophen overdose toxicity.

Abstract
The use of analgesics increases with age and on any given day 20-30% of older adults take an analgesic medication. Over-the-counter (OTC) analgesics are generally well tolerated and effective when taken for brief periods of time and at recommended dosages. However, their long-term use, use at inappropriately high doses, or use by persons with contraindications may result in adverse effects, including gastrointestinal haemorrhage, cardiovascular toxicity, renal toxicity and hepatotoxicity. Many OTC drugs are also available through a prescription, for a broader range of indications and for longer durations of use and wider dose ranges, under the assumption that healthcare providers will help patients make safe choices about analgesics. Safe and effective use of medications is one of the greatest challenges faced by healthcare providers in medicine. More than 60% of people cannot identify the active ingredient in their brand of pain reliever. Additionally, about 40% of Americans believe that OTC drugs are too weak to cause any real harm. As a result of a recent US FDA policy, the conversion of prescription to OTC medications will result in a 50% increase of OTC medications. To reduce the risks of potential adverse effects from OTC drug therapy in older adults, we propose that the use of analgesics will be enhanced through the use of patient and healthcare provider education, as well as improved labelling of OTC analgesics. Improved labelling of OTC analgesics may help consumers distinguish common analgesic ingredients in a wide variety of preparations and facilitate informed decisions concerning the use of OTC drugs.

Abstract
BACKGROUND There is controversy as to whether compulsory community treatment for psychiatric patients reduces hospital admission rates. AIMS To examine whether community treatment orders (CTOs) reduce admission rates, using a two-stage design of matching and multivariate analyses to take into account socio-demographic factors, clinical factors, case complexity and previous psychiatric and forensic history. METHOD Survival analysis of CTO cases and controls from three linked Western Australian databases of health service use, involuntary treatment and forensic history. We used two control groups: one matched on demographic characteristics, diagnosis, past psychiatric history and treatment setting, and consecutive controls matched on date of discharge from in-patient care. RESULTS We matched 265 CTO cases with 265 matched controls and 224 consecutive controls (total n=754). The CTO group had a significantly higher readmission rate: 72% v. 65% and 59% for the matched and consecutive controls (log-rank chi(2)=4.7, P=0.03). CTO placement, aboriginal ethnicity, younger age, personality disorder and previous health service use were associated with increased admission rates. CONCLUSIONS Community treatment orders alone do not reduce admissions.

Abstract
OBJECTIVE To examine the number of hospital discharges and 30-day case fatalities due to drug poisoning based on data from a Danish County Hospital Discharge Registry from 1979 to 2002. METHODS All patients with a hospital discharge diagnosis of drug poisoning were identified and separated into groups taking: (1) opioid analgesics; (2) non-opioid analgesics; (3) anxiolytics; (4) antidepressants; (5) antipsychotics; or (6) non-specified. Paracetamol and salicylate were analysed separately. From 1994 to 2001, the total amount of drugs sold in the county was identified from a national drug database. RESULTS A total of 13,432 patients with a median age 41.5 years at discharge of whom 59% were females accounted for 20,249 discharges for drug poisoning. The overall number of discharges remained essentially stable around 170 discharges per 100,000 inhabitants per year. From the mid-1990's, paracetamol became the most frequently used drug in poisoning with the largest increase in female teenagers. Thirty-day case fatality in poisoning with opioids was 3.6% compared with around 1% in other drug categories. For most drug categories, a sale of around 80,000 defined daily doses was associated with one hospital discharge due to drug poisoning. CONCLUSION The overall number of hospital discharges remained stable and seems primarily related to amount of drugs available. With almost 10 years delay, the easier access to paracetamol was followed by an increase in hospitalisation due to poisoning with paracetamol. However, although the majority of hospitalisations were found in the younger age group, the highest mortality was seen among the elderly.
