Questionnaires are better than laboratory tests to screen for current alcohol abuse or dependence in a male inpatient population

Lay counsellors' experiences of administering the AUDIT-C as a brief screening tool in a South African township

BACKGROUND

South Africa presents one of the riskiest patterns of alcohol consumption, with per capita consumption above the African regional average. Globally, there has been an increased focus on the potential of appointing lay counsellors to administer alcohol intervention strategies in resource-limited contexts. Given the increasing need for relevant and efficient intervention strategies in response to high-risk alcohol consumption, screening instruments such as the AUDIT-C have gained increased attention.

METHODS

This paper explores the experiences of 15 lay counsellors in response to the training received on how to administer the AUDIT-C instrument, as well as provide interventions such as brief advice or an appropriate referral, in the resource-limited South African township of Alexandra, Johannesburg. A focus group was facilitated for this purpose and, thereafter, a thematic content analysis was applied to identify the themes most central to the lay counsellors' experiences.

RESULTS

The research findings suggest that the lay counsellors perceived the training to be adequate in preparing them for administrating the AUDIT-C and for providing any relevant interventions, and that their confidence in administering the instrument developed as the project progressed. However, recruitment and administration challenges were experienced in primary healthcare and community settings, and lay counsellors perceived home visits to be more appropriate with respect to issues related to confidentiality and stigmatisation.

CONCLUSION

Overall, while lay counsellors feel that the training they received on the tool and the tool itself is useful for effectively implementing the AUDIT-C in low-resource communities, the availability and efficiency of alcohol treatment services in Alexandra Township need to be improved.

The effect of maternal alcohol and drug abuse on first trimester screening analytes: a retrospective cohort study

Background

The purpose of this study was to determine whether first trimester trisomy screening (FTS) parameters are affected by alcohol and drug use.

Methods

A routine combined FTS including measurements of maternal serum levels of free β-human chorionic gonadotropin subunit (free β-hCG) and pregnancy-associated plasma protein A (PAPP-A) were measured at 9–11 weeks of gestation, and fetal nuchal translucency thickness (NTT) at 11–13 weeks of gestation. In total 544 women with singleton pregnancies [71 alcohol and drug abusers, 88 smokers, 168 non-smokers delivering a small for gestational age (SGA) child, and 217 unexposed control women] were assessed.

Results

Free β-hCG levels were higher in alcohol and drug abusing than in unexposed pregnant women [mean 1.5 vs. 1.2 multiples of medians (MoM); P = 0.013]. However, stepwise multiple linear regression analyses suggested that smoking could explain increased free β-hCG. Additionally, we observed lower PAPP-A levels in the smoking mothers (0.9 vs. 1.2 MoM; P = 0.045) and in those giving birth to an SGA child compared to the controls (1.1 vs.. 1.2 MoM; P < 0.001). Fetal NTT did not differ significantly between any of the groups.

Conclusions

The present study shows increased free β-hCG levels in alcohol and drug abusers, but maternal smoking may explain the result. Maternal serum PAPP-A levels were lower in smoking than non-smoking mothers, and in mothers delivering an SGA child. However, FTS parameters (PAPP-A, free β-hCG and NTT) seem not to be applicable for the use as alcohol biomarkers because of their clear overlap between alcohol abusers and healthy controls.

The associations of interpersonal sensitivity with mental distress and trait aggression in early adulthood: a prospective cohort study

BACKGROUND

To explore the longitudinal associations of interpersonal sensitivity (IS) with mental distress and trait aggression among participants passing through adolescence into adulthood.

METHODS

A total of 306 participants were recruited at baseline and received a 24-month follow-up. Questionnaires investigating sociodemographics; IS; depression, anxiety, and stress; and trait aggression were used. Univariable and multivariable logistic regression and cross-lagged analyses were also performed.

RESULTS

At base, 22.5%, 18.3%, 24.2%, and 9.2% of the participants reported higher levels of IS, depressive, anxious, and stressful symptoms. IS at baseline was a partial risk factor for new problems, including anxiety, stress, and anger at follow-up. Newly developed or persistent IS was significantly associated with ongoing symptoms. Discontinued IS, however, only resolved the association with stress and anxiety symptoms. Similarly, newly developed or persistent IS was significantly associated with increased persistence of some problems (anxiety symptoms and physical aggression), while the discontinuation of IS was associated with a lessening of these outcomes. Cross-lagged analyses revealed bidirectional associations of IS with anxiety symptom and stress symptom.

LIMITATIONS

All subjects were recruited from one medical college, which could limit applicability. This study had a relatively small sample size. Self-reported questionnaires can lead to recall bias. Further research is needed to test causality.

CONCLUSIONS

IS can predict adolescents' newly developed partial mental distress and aggression. Our findings highlight the crucial role of early recognition of both higher levels of interpersonal sensitivity and associated behavioral problems.

Factors associated with discontinuation of methadone maintenance therapy (MMT) among persons who use alcohol in Vancouver, Canada

BACKGROUND

We sought to examine the factors associated with discontinuation of MMT among persons on methadone who use alcohol.

METHODS

We evaluated the impact of drug-related and other factors on discontinuation of MMT among persons enrolled in MMT and who reported any use of alcohol versus those who were enrolled in two community-recruited prospective cohorts of people who use illicit drugs (PWUD). Extended Cox models with time-dependent variables identified factors independently associated with time to first MMT discontinuation.

RESULTS

Between December 2005 and 2015, 823 individuals on MMT who also reported using alcohol at least once were included in these analyses. During the study period, 391 (47.5%) discontinued methadone. Daily heroin injection (Adjusted Hazard Ratio [AHR] = 2.67, 95% Confidence Interval [CI]: 2.10-3.40) and homelessness (AHR = 1.42, 95% CI: 1.10-1.83) were positively associated with MMT discontinuation, whereas receiving other concurrent addiction treatment in addition to MMT (AHR = 0.07, 95% CI: 0.05-0.08), as well as >60 mg methadone dose (AHR = 0.48, 95% CI: 0.39-0.60), Hepatitis C virus seropositivity (AHR = 0.65, 95% CI: 0.47-0.90), and HIV seropositivity (AHR = 0.72, 95% CI: 0.57-0.91) were negatively associated with MMT discontinuation. Any/heavy alcohol use was not independently associated with MMT discontinuation.

CONCLUSIONS

This study reinforces the known risks of continued heroin injection and homelessness for MMT discontinuation among individuals who also consume alcohol and highlights the protective effect of both MMT dose and receipt of concurrent addiction treatment.

Prevalence of Heavy Alcohol Use Among People Receiving Methadone Following Change to Methadose

BACKGROUND

A recent switch in methadone formulation from methadone (1 mg/mL) to Methadose (10 mg/mL) in British Columbia (BC), Canada, was associated with increased reports of opioid withdrawal and increases in illicit opioid use. Impacts on other forms of drug use have not been assessed. Since alcohol use is common among people receiving Medication-Assisted Treatment (MAT), we assessed if switch was associated with increased prevalence of heavy alcohol use.

METHODS

Drawing on data from two open prospective cohort studies of people who inject drugs in Vancouver, BC, generalized estimating equations (GEE) model examined relationship between methadone formulation change and heavy alcohol use, defined by National Institute for Alcohol Abuse and Alcoholism (NIAAA). A sub-analysis examined relationship with heavier drinking defined as at least eight drinks per day on average in last six months.

RESULTS

Between June 2013 and May 2015, a total of 787 participants on methadone were eligible for the present analysis, of which 123 (15.6%) reported heavy drinking at least once in last six months. In an unadjusted GEE model, Methadose use was not significantly associated with an increased likelihood of heavy drinking [Odds Ratio (OR) = 1.03; 95% Confidence interval (CI) = 0.87-1.21]. Methadose use was not significantly associated with an increased likelihood of drinking at least eight drinks daily on average (OR = 1.09, 95% CI = 0.72-1.65).

CONCLUSIONS

Despite reported changes in opioid use patterns coinciding with the change, there appeared to be no effect of the methadone formulation change on heavy drinking in this setting.

Mental health problems in college freshmen: Prevalence and academic functioning

BACKGROUND

Mental health problems in college and their associations with academic performance are not well understood. The main aim of this study was to investigate to what extent mental health problems are associated with academic functioning.

METHODS

As part of the World Mental Health Surveys International College Student project, 12-month mental health problems among freshmen (N = 4921) was assessed in an e-survey of students at KU Leuven University in Leuven, Belgium. The associations of mental health problems with academic functioning (expressed in terms of academic year percentage [or AYP] and grade point average [GPA]) were examined across academic departments.

RESULTS

Approximately one in three freshman reports mental health problems in the past year, with internalizing and externalizing problems both associated with reduced academic functioning (2.9-4.7% AYP reduction, corresponding to 0.2-0.3 GPA reduction). The association of externalizing problems with individual-level academic functioning was significantly higher in academic departments with comparatively low average academic functioning.

LIMITATIONS

Limited sample size precluded further investigation of interactions between department-level and student-level variables. No information was available on freshman secondary school academic performance.

CONCLUSIONS

Mental health problems are common in college freshman, and clearly associated with lower academic functioning. Additional research is needed to examine the potentially causal nature of this association, and, if so, whether interventions aimed at treating mental health problems might improve academic performance.

Using the AUDIT-PC to predict alcohol withdrawal in hospitalized patients

BACKGROUND

Alcohol withdrawal syndrome (AWS) occurs when alcohol-dependent individuals abruptly reduce or stop drinking. Hospitalized alcohol-dependent patients are at risk. Hospitals need a validated screening tool to assess withdrawal risk, but no validated tools are currently available.

OBJECTIVE

To examine the admission Alcohol Use Disorders Identification Test-(Piccinelli) Consumption (AUDIT-PC) ability to predict the subsequent development of AWS among hospitalized medical-surgical patients admitted to a non-intensive care setting.

DESIGN

Retrospective case–control study of patients discharged from the hospital with a diagnosis of AWS. All patients with AWS were classified as presenting with AWS or developing AWS later during admission. Patients admitted to an intensive care setting and those missing AUDIT-PC scores were excluded from analysis. A hierarchical (by hospital unit) logistic regression was performed and receiver-operating characteristics were examined on those developing AWS after admission and randomly selected controls. Because those diagnosing AWS were not blinded to the AUDIT-PC scores, a sensitivity analysis was performed.

PARTICIPANTS

The study cohort included all patients age ≥18 years admitted to any medical or surgical units in a single health care system from 6 October 2009 to 7 October 2010.

KEY RESULTS

After exclusions, 414 patients were identified with AWS. The 223 (53.9 %) who developed AWS after admission were compared to 466 randomly selected controls without AWS. An AUDIT-PC score ≥4 at admission provides 91.0 % sensitivity and 89.7 % specificity (AUC=0.95; 95 % CI, 0.94–0.97) for AWS, and maximizes the correct classification while resulting in 17 false positives for every true positive identified. Performance remained excellent on sensitivity analysis (AUC=0.92; 95 % CI, 0.90–0.93). Increasing AUDIT-PC scores were associated with an increased risk of AWS (OR=1.68, 95 % CI 1.55–1.82, p<0.001).

CONCLUSIONS

The admission AUDIT-PC score is an excellent discriminator of AWS and could be an important component of future clinical prediction rules. Calibration and further validation on a large prospectivecohort is indicated.

Early data from Project Engage: a program to identify and transition medically hospitalized patients into addictions treatment

Background

Patients with untreated substance use disorders (SUDs) are at risk for frequent emergency department visits and repeated hospitalizations. Project Engage, a US pilot program at Wilmington Hospital in Delaware, was conducted to facilitate entry of these patients to SUD treatment after discharge. Patients identified as having hazardous or harmful alcohol consumption based on results of the Alcohol Use Disorders Identification Test-Primary Care (AUDIT-PC), administered to all patients at admission, received bedside assessment with motivational interviewing and facilitated referral to treatment by a patient engagement specialist (PES). This program evaluation provides descriptive information on self-reported rates of SUD treatment initiation of all patients and health-care utilization and costs for a subset of patients.

Methods

Program-level data on treatment entry after discharge were examined retrospectively. Insurance claims data for two small cohorts who entered treatment after discharge (2009, n = 18, and 2010, n = 25) were reviewed over a six-month period in 2009 (three months pre- and post-Project Engage), or over a 12-month period in 2010 (six months pre- and post-Project Engage). These data provided descriptive information on health-care utilization and costs. (Data on those who participated in Project Engage but did not enter treatment were unavailable).

Results

Between September 1, 2008, and December 30, 2010, 415 patients participated in Project Engage, and 180 (43%) were admitted for SUD treatment. For a small cohort who participated between June 1, 2009, and November 30, 2009 (n = 18), insurance claims demonstrated a 33% ($35,938) decrease in inpatient medical admissions, a 38% ($4,248) decrease in emergency department visits, a 42% ($1,579) increase in behavioral health/substance abuse (BH/SA) inpatient admissions, and a 33% ($847) increase in outpatient BH/SA admissions, for an overall decrease of $37,760. For a small cohort who participated between June 1, 2010, and November 30, 2010 (n = 25), claims demonstrated a 58% ($68,422) decrease in inpatient medical admissions; a 13% ($3,308) decrease in emergency department visits; a 32% ($18,119) decrease in BH/SA inpatient admissions, and a 32% ($963) increase in outpatient BH/SA admissions, for an overall decrease of $88,886.

Conclusions

These findings demonstrate that a large percentage of patients entered SUD treatment after participating in Project Engage, a novel intervention with facilitated referral to treatment. Although the findings are limited by the retrospective nature of the data and the small sample sizes, they do suggest a potentially cost-effective addition to existing hospital services if replicated in prospective studies with larger samples and controls.

The fast alcohol screening test (FAST) is as good as the AUDIT to screen alcohol use disorders

This study was aimed at assessing the psychometric qualities of the fast alcohol screening test (FAST), and at comparing these qualities to those of the alcohol use disorders identification test (AUDIT) in three samples of Brazilian adults: (i) subjects attended at an emergency department (530); (ii) patients from a psychosocial care center (40); and (iii) university students (429). The structured clinical interview for diagnosis (SCID)-IV was used as gold standard. The FAST demonstrated high test-retest and interrater reliability coefficients, as well as high predictive and concurrent validity values. The results attest the validity and reliability of the Brazilian version of the FAST for the screening of indicators of alcohol abuse and dependence.

Is the full version of the AUDIT really necessary? Study of the validity and internal construct of its abbreviated versions

BACKGROUND

This study was aimed at assessing the psychometric qualities of the abbreviated versions of the Alcohol Use Disorders Identification Test (AUDIT-3, AUDIT-4, AUDIT-C, AUDIT-PC, AUDIT-QF, FAST, and Five-Shot) and at comparing them to the 10-item AUDIT and the CAGE in 2 samples of Brazilian adults.

METHODS

The validity and internal consistency of the scales were assessed in a sample of 530 subjects attended at an emergency department and at a Psychosocial Care Center for Alcohol and Drugs. The Structured Clinical Interview for DSM-IV was used as the diagnostic comparative measure for the predictive validity assessment. The concurrent validity between the scales was analyzed by means of Pearson's correlation coefficient.

RESULTS

The assessment of the predictive validity of the abbreviated versions showed high sensitivity (of 0.78 to 0.96) and specificity (of 0.74 to 0.94) indices, with areas under the curve as elevated as those of the AUDIT (0.89 and 0.92 to screen for abuse and 0.93 and 0.95 in the screening of dependence). The CAGE presented lower indices: 0.81 for abuse and 0.87 for dependence. The analysis of the internal consistency of the AUDIT and its versions exhibited Cronbach's alpha coefficients between 0.83 and 0.94, while the coefficient for the CAGE was 0.78. Significant correlations were found between the 10-item AUDIT and its versions, ranging from 0.91 to 0.99. Again, the results for the CAGE were satisfactory (0.77), although inferior to the other instruments.

CONCLUSIONS

The results obtained in this study confirm the validity of the abbreviated versions of the AUDIT for the screening of alcohol use disorders and show that their psychometric properties are as satisfactory as those of the 10-item AUDIT and the CAGE.

Performance of screening instruments for alcohol use disorders in emergency department patients in Argentina

The performance of the Alcohol Use Disorders Identification Test (AUDIT), CAGE, Brief Michigan Alcohol Screening Test (Brief MAST), Rapid Alcohol Problems Screen (RAPS), Rapid Alcohol Problems Screen-Quantity and Frequency (RAPS4-QF), and TWEAK was evaluated against a diagnosis of alcohol dependence and harmful drinking or alcohol abuse from ICD-10 and DSM-IV criteria. Data were collected from a probability sample of 779 patients admitted to the emergency department of a public general hospital in Mar del Plata, Argentina, during the year 2001. The majority of the patients sampled were male. The age range was 18 to 89 years, with a mean value of 36 years and a median of 31 years. Almost half of the sample had an elementary school education or less. All instruments were more sensitive for alcohol dependence than for harmful drinking or abuse and more sensitive for men than for women. Findings suggest the RAPS4 and RAPS4-QF may be preferred when screening for alcohol use disorders in the emergency department in Argentina. The study's limitations are noted.

Carbohydrate-deficient transferrin (CDT) as a marker of alcohol abuse: a critical review of the literature 2001-2005

The diagnosis of alcohol abuse based on objective data is a necessary requirement in both clinical and forensic environments. Among the different biomarkers of chronic alcohol abuse, carbohydrate-deficient transferrin (CDT) is world wide recognized as the most reliable indicator. However, several problems about the real meaning of CDT and the reliability of its use for the diagnosis of alcohol abuses are still open, as reported by numerous research articles and reviews. The present article presents a critical review of the literature on CDT appeared in the period from 2001 to 2005 (included). The article is organized in the following sections: (1) introduction, (2) definition and structure of human serum CDT, (3) pathomechanisms of the ethanol-induced CDT increase, (4) preanalysis, (5) analysis, (6) data interpretation, (7) review papers, (8) conclusions. As many as 127 papers appeared in the international literature and retrieved by the search engines PubMed and Scopus are quoted.

EFNS guideline on the diagnosis and management of alcohol-related seizures: report of an EFNS task force

Despite being a considerable problem in neurological practice and responsible for one-third of seizure-related admissions, there is little consensus as to the optimal investigation and management of alcohol-related seizures. The final literature search was undertaken in September 2004. Consensus recommendations are given graded according to the EFNS guidance regulations. To support the history taking, use of a structured questionnaire is recommended. When the drinking history is inconclusive, elevated values of carbohydrate-deficient transferrin and/or gammaglutamyl transferase can support a clinical suspicion. A first epileptic seizure should prompt neuroimaging (CT or MRI). Before starting any carbohydrate containing fluids or food, patients presenting with suspected alcohol overuse should be given prophylactic thiamine parenterally. After an alcohol withdrawal seizure (AWS), the patient should be observed in hospital for at least 24 h and the severity of withdrawal symptoms needs to be followed. For patients with no history of withdrawal seizures and mild to moderate withdrawal symptoms, routine seizure preventive treatment is not necessary. Generally, benzodiazepines are efficacious and safe for primary and secondary seizure prevention; diazepam or, if available, lorazepam, is recommended. The efficacy of other drugs is insufficiently documented. Concerning long-term recommendations for non-alcohol dependent patients with partial epilepsy and controlled seizures, small amounts of alcohol may be safe. Alcohol-related seizures require particular attention both in the diagnostic work-up and treatment. Benzodiazepines should be chosen for the treatment and prevention of recurrent AWS.

The value of the CAGE in screening for alcohol abuse and alcohol dependence in general clinical populations: a diagnostic meta-analysis

OBJECTIVE

To perform a meta-analysis to assess diagnostic characteristics of the CAGE in screening for alcohol abuse or dependence in a general clinical population and to test a new method for pooling of ROC curves.

METHODS

Medline search performed over the period 1/1/1974 to 31/12/2001.

MEASUREMENT

Calculation of diagnostic values.

RESULTS

We identified 35 articles using the DSM criteria as the gold standard to test the diagnostic value of the CAGE. Only 10 studies could be included for the meta-analysis. With a cutoff point > or =2, the pooled sensitivity is far better in inpatients (0.87) than in primary care patients (0.71) or ambulatory patients (0.60). The pooled specificity also differs for each group. The likelihood ratios seem to be relatively constant over the populations (overall LR+:3.44;LR-:0.18). We calculated a pooled AUC of 0.87 (95% CI 0.85-0.89). At low specificity values, the sensitivity was homogeneous over the studies, and at a low sensitivity, the specificity was heterogeneous.

CONCLUSION

The diagnostic value of the CAGE is of limited value using this test for screening purposes at his recommended cutpoint of > or =2.
