The Association between the Alcohol Biomarker Phosphatidylethanol (PEth) and Self-Reported Alcohol Consumption among Russian and Norwegian Medical Patients.

AIMS: Valid measures to identify harmful alcohol use are important. Alcohol Use Disorders Identification Test (AUDIT) is a validated questionnaire used to self-report harmful drinking in several cultures and settings. Phosphatidylethanol 16:0/18:1 (PEth) is a direct alcohol biomarker measuring alcohol consumption levels. The aim of this study was to investigate how PEth levels correlate with AUDIT-QF and weekly grams of alcohol consumed among patients in two urban hospitals. In addition, we wanted to investigate the predictive value of PEth in identifying harmful alcohol use as defined by AUDIT-QF and weekly grams of alcohol cutoffs. METHODS: A cross-sectional study comprising acute medically ill patients with measurable PEth levels (≥0.030 µM) admitted to two urban hospitals in Oslo, Norway (N = 931) and Moscow, Russia (N = 953) was conducted using PEth concentrations in whole blood, sociodemographic data and AUDIT-QF questionnaires. RESULTS: PEth levels from patients with measurable PEth were found to be positively correlated with AUDIT-QF scores, with PEth cutpoints of 0.128 µM (Oslo) and 0.270 µM (Moscow) providing optimal discrimination for harmful alcohol use defined by AUDIT-QF (the difference between cities probably reflecting different national drinking patterns in QF). When converting AUDIT-QF into weekly grams of alcohol consumed, the predictive value of PEth improved, with optimal PEth cutpoints of 0.327 (Oslo) and 0.396 (Moscow) µM discriminating between harmful and non-harmful alcohol use as defined in grams (≥350 grams/week). CONCLUSIONS: By using PEth levels and converting AUDIT-QF into weekly grams of alcohol it was possible to get an improved rapid and sensitive determination of harmful alcohol use among hospitalized patients.

Prevalence of psychoactive substance use among acutely hospitalised patients in Oslo and Moscow: a cross-sectional, observational study.

OBJECTIVES: The use of psychoactive prescription medication is increasing in the general population. This is a cause for concern, particularly among the elderly, where physiological changes related to senescence increase the risk for adverse effects. While previous studies regarding psychoactive substance use have generally been population based, we sought to determine the frequency of such use among acutely hospitalised patients. SETTING: Two emergency departments (EDs), one in Oslo and one in Moscow, admitting patients to Departments of Internal Medicine. PARTICIPANTS: 5583 patients aged ≥18 years participated, distributed evenly between genders and study locations. Patients unable to give informed consent were excluded. The study sites did not admit patients with surgical conditions and/or injuries. PRIMARY AND SECONDARY OUTCOMES: The presence of psychoactive substances was determined through blood analysis using liquid chromatography-mass spectrometry. Secondary outcomes comprised demographic data (including age, gender, employment and marital status), degree of psychological distress, concurrent alcohol use, and self-reported alcohol, psychoactive drug and illicit substance use. RESULTS: 32.3% in Oslo and 12% in Moscow were positive for one or more psychoactive medicinal drugs (benzodiazepines, z-hypnotics, opioids or barbiturates). In Oslo, medicinal drug use was associated with being aged 61 to 70 years (OR 2.40, 95% CI 1.61 to 3.58) compared with 18 to 40 years, and psychological distress (OR 2.61, 95% CI 2.06 to 3.30). In Moscow, psychoactive medicinal drug use was also associated with psychological distress (OR 1.68, 95% CI 1.18 to 2.39), and was less common among patients aged 41 to 60 years (OR 0.62, 95% CI 0.43 to 0.88) than among patients aged 18 to 40 years. CONCLUSION: A significant proportion of admitted patients used one or more psychoactive medicinal drugs, in particular benzodiazepines (Oslo and Moscow) and opiates (Oslo). We suggest formalised screening for inappropriate prescription drug use and increased adherence to clinical prescription guidelines.

Predictors of tobacco smoking among acutely ill patients in a Moscow hospital: A cross-sectional study.

INTRODUCTION: Tobacco smoking is a major preventable risk factor for non-communicable diseases. The aim of this study was to investigate predictors of tobacco smoking among acute medically ill patients admitted to a Moscow hospital, and the association between smoking and alcohol use. METHODS: Patients admitted to the V. P. Demikhov hospital in Moscow from November 2016 through December 2017 were asked to participate in this study (inclusion criteria were acute medically ill patients aged ≥18 years). Sociodemographic data were collected, in addition to questionnaires on mental distress (Hopkins Symptom Checklist 5), alcohol use (Alcohol Use Disorder Identification Test 4, AUDIT-4) and smoking (Fagerström Test for Nicotine Dependence). RESULTS: A total of 3009 patients were recruited to the study. Using a binary logistic regression model adjusted for all variables, it was found that living without a partner resulted in a higher risk of smoking tobacco compared to being married or living with a partner (odds ratio, OR=1.60 for divorced, p=0.001; and OR=1.62 for single, p=0.002), and being economically non-active resulted in a higher risk compared to being economically active (OR=1.47; p=0.003). Harmful alcohol use (AUDIT-4 score ≥5 [for females] / 7 [for males]) resulted in a higher risk of smoking compared to those without harmful alcohol use (OR=4.04; p<0.001). CONCLUSIONS: Smoking was highly prevalent and associated with other adverse sociodemographic and lifestyle factors such as harmful alcohol use.
