Service Data

Objective: Amphetamine use and availability have increased in Australia and there are concerns that this has led to more frequent hospital admissions with amphetamine-related psychosis. This study examines whether amphetamine-related admissions to mental health units are more common at times of greater amphetamine availability. Methods: We conducted an ecological study using aggregate crime and health service data for NSW, Australia, from January 2000 to March 2015. Amphetamine-related criminal incidents (arrests or cautions for possession or use) were used as an indirect measure of amphetamine availability. Semiparametric time series analysis was used to compare monthly arrest rates to monthly hospitalisation rates for (1) amphetamine abuse or dependence, (2) amphetamine-related psychosis and (3) any psychosis. Results: Amphetamine-related admissions to NSW mental health units have increased four- to fivefold since 2009 and comprised approximately 10% of all admissions to these units in early 2015. There was a significant association between arrests and amphetamine-related admissions. After adjustment for seasonal variation, this effect demonstrated a time lag of 1–2 months. There was no relationship between amphetamine arrests and overall admissions for psychosis. Conclusion: Greater amphetamine availability significantly predicts admissions for amphetamine use disorders and amphetamine-related psychosis. Better treatment strategies are needed to break the nexus between drug availability and drug-related harm.

The Impact

AbstractBackgroundDuring the coronavirus disease 2019 (COVID-19) pandemic, there have been health concerns related to alcohol use and misuse. Therefore, the World Health Organization cautioned that alcohol consumption during the pandemic might have a negative impact. The aim of this study was to examine the population-level change in cases of alcohol-related liver disease and pancreatitis that required admission during the COVID-19 outbreak.MethodsWe included patients aged 18 years or older who were hospitalized between July 2018 and June 2020 using Diagnostic Procedure Combination data, an administrative database in Japan, and counted the admission cases whose primary diagnosis was alcohol-related liver disease or pancreatitis. We defined the period from April 2020, when the Japanese government declared a state of emergency, as the beginning of the COVID-19 outbreak. The rate ratio (RR) of admissions with alcohol-related liver disease or pancreatitis per 1,000 admissions was tested using interrupted time series analysis. In addition, excess admissions for alcohol-related liver disease or pancreatitis were calculated.ResultsOverall admissions were 3,026,389 cases, and a total of 10,242 admissions for alcohol-related liver disease or pancreatitis occurred from 257 hospitals. The rate of admissions per 1,000 admissions during the COVID-19 outbreak period (April 2020 to June 2020) had a 1.2 times increase compared with the pre-outbreak period (July 2018 to March 2020) for cases of alcohol-related liver disease or pancreatitis (RR: 1.22, 95%Confidence interval [CI]: 1.12 to 1.33). The COVID-19 pandemic caused about 214.75 (95%CI: 178.78 to 249.72) excess admissions for alcohol-related liver disease or pancreatitis based on predictions from our model.ConclusionThe COVID-19 outbreak might have resulted in increased hospital admissions for alcohol-related liver disease or pancreatitis.
